Description

Tampon Assembly, Use Of A Tampon Assembly, Method, And Use Of Ά Compressed Gas Container

The invention relates to a tampon assembly comprising an absorbent body and a vibration generator that is connected thereto . The invention further relates to a use of a tampon assembly, to a method for absorbing body fluids in a vagina and/or for applying a vibration to a female body in the area of the vagina , and to a use of a pressure container.

Vibrating tampon assemblies are known, e.g. from the

reference ΞΡ1231885 Bl . This arrangement serves for

relieving menstrual pain and comprises an electrically operated vibration generator arranged in a tampon and an energy supply unit that is connected to the tampon by a cable and in which are arranged an energy source and an operating element in the form of a push button that controls the electric connection between the electric energy source and the vibration generator . Although the voltage used for the operation of the vibration generator is relatively low, e.g. 1.35 volt , and all electric components are electrically insulated, many potential users are reluctant to lead electric current into their body .

On the background of this prior ar , it is the obj ect of the invention to provide a tampon assembly comprising a

vibration generator that is connected to a tampon and where no electric current is lead to the tampon in operation .

According to the invention, this obj ect is achieved in that the tampon assembly comprises a flow generator for a fluid that is operatively connected or operatively connectable to the vibration generator by a fluid duct . By a pressure variation and/or a fluid flow in the fluid duct , the vibration generator and thus also the absorbent body can be set into vibration .

The use of a fluid as a means of energy transport allows operating the vibration generator without electric current . Depending on the design of the components conducting the fluid, the latter may be a gas or a liquid . The term "flow generator" is meant to include any means that is apt to generate a flow in the fluid . Thus , the flow generator may be a pum , more particularly a pump having reversible suction and pressure directions , a blower, a compressor, a turbine , etc . Thus , in a very general manner, the flow generator may be a fluid energy machine and/or a fluid pressure generator as described below .

The tampon assembly may comprise the flow generator - optionally in the form of a separate component from the absorbent body . However, the invention also encompasses tampon assemblies that do not comprise the flow generator but whose vibration generator is merely operatively

connectable to a flow generator by the fluid duct .

The fluid duct preferably has a length of at least 20 mm, preferably at least 50 mm . Such a length allows arranging the flow generator, or the energy supply unit containing the flow generator, respectively, outside the body of the person who is wearing the tampon assembly .

To allow an easy handling and to ensure the best possible wearing comfort , according to a preferred variant of the invention, the flow generator may be contained in the energy supply unit that forms a constructional unit together with the flow generator. Alternatively, however, the flow generator and the energy supply unit may be two distanced components that are connectable or connected to each other by a duct . The length of this duct may be at least 20 mm, preferably at least 50 mm .

According to an embodiment of the invention that has a very compact design and a high efficiency regarding the

generation of a fluid flow, the flow generator forms a constructional unit with the absorbent body and the

vibration generator . An energy supply unit may be arranged at a distance of at least 20 mm from the absorbent body . According to an embodiment of the invention that

distinguishes itself by a very reliable operation and a simple construction, the low generator may comprise a fluid pressure generator . According to a particularly advantageous development of this variant that distinguishes itsel f by a particularly easy handling, the fluid pressure generator may comprise or consist of a pressure container that is

pref illed with a pressure fluid, e.g. a compressed gas cartridge . According to a development of this variant of the inven ion, the fluid pressure generator may also comprise a refillable pressure container . An advantage of this variant is that the fluid may flow back, into the ref illable pressure container when the flow direction is reversed.

A modular construction that allows an easy and quick

exchange of individual components can be realized in that the fluid pressure generator and/or the pressure container can be coupled to the flow generator and/or to the vibration generator by a quick-lock coupling .

In order to avoid excessive pressures and to ensure maximum safety in use, a preferably adjustable pressure reducing and/or pressure relief valve may be provided between the fluid pressure generator and the pressure container .

According to an advantageous variant of the invention, an additional fluid duct is connected to the vibration

generator . This variant allows e.g. real izing a closed fluid circuit : The fluid may flow into the vibration generator through the first fluid duct according to the invention and flow out through the additional fluid duct .

An easy replacement of the fluid duct can be achieved in that the fluid duct is equipped with releasable coupling means at its end that is connected to the flow generator and/or at its end that is connected to the vibration

generator .

According to a variant of the invention that also

distinguishes itself by a simple design, the vibration generator comprises at least one body that can be set into rotation by a fluid flow . In this regard it has been found to be advantageous if guiding means for guiding the body on an orbit are provided .

Alternatively to the last mentioned variant it may also be advantageous , however, that the body is rotatably arranged on an axle or a shaft . This is advantageous particularly when the shaft is connected to a turbine . To ensure a reliable vibration, the vibration generator may comprise at least one body to which an oscillating movement can be imparted by a compressed fluid. In this regard it has been found to be advantageous if the body is in the form of a piston that is guided inside a cylinder, or of a lamella .

According to a further variant of the invention, the

vibration generator may comprise an elastic hollow body to which a fluid pressure can be applied.

To ensure an easy removal of parts of the tampon assembly that are located inside the body, at least a preferably flexible removal member, more particularly a pulling element such as a thread or a string, may be fastened to the

vibration generator and/or to the absorbent body .

An easy replacement of the fluid pressure generator or of the pressure container, respectively, can be achieved in that the fluid pressure generator and/or the pressure container is apt to be coupled to the flow generator and/or to the vibration generator by a quick-lock coupling .

To allow an easy replaceability of the absorbent body or of the vibration generator, respectively, and a reusability of the other components , the absorbent body and the vibration generator and/or the flow generator may be provided with cooperating coupling parts .

To avoid any contact between the coupling means of the absorbent body and the interior of the body, the coupling part of the absorbent body may be located inside a hollow space that is at least partly and preferably entirely enclosed in the absorbent body. A further aspect of the invention relates to the use of a tampon assembly as described above for absorbing body fluids in a vagina and/or for applying a vibration to a female body in the area of the vagina . According to the invention, the absorbent body that is connected to the vibration generator is introduced into the vagina . The flow generator can be removably attached to the surface of the body and/or to a garment . It may e.g. be fastened to the surface of the body by means of an adhesive bandage . The garment may e.g. be a slip . Alternatively thereto, it may also be fastened to a user ' s panty liner.

Yet a further aspect of the invention relates to a method for absorbing body fluids in a vagina and/or for applying a vibration to a female body in the area of the vagina by means of an absorbent body introduced into the vagina . The vibration generator is to be connected to a flow generator and optionally also to an energy source . Vibrations can be applied at least intermittently to the vibration generator by the flow generator . After a presettable duration, the absorbent body including the vibration generator can be removed and disposed of . By a pressure variation and/or a fluid flow, the vibration generator and thus also to the absorbent body can be set into vibration .

Furthermore , the invention also relates to the use of a pressure container, more particularly a compressed gas cartridge , as a flow generator in a tampon assembly, more particularly a tampon assembly as described above .

Particular embodiments of the invention are described in the dependent claims. Exemplary embodiments of the invention will be explained in more detail hereinaf er by way of examples with reference to the accompanying drawings . The latter schematically show

Figure 1 shows an exemplary embodiment of a tampon assembly 1 according to the invention in a schematic illustration . The assembly comprises a tampon-like absorbent body 2 of an absorbent material and a vibration generator 3 that is arranged in a housing 4.

Hereinafter, the structure of tampon assembly 1 will be briefly discussed, the following explanations regarding the structure of tampon assembly 1 of the invention and the features mentioned therein being combinable individually or in any combination with the different embodiments and the features in the following exemplary embodiments .

The present tampon or tampon-like absorbent body 2 ,

respectively, has a proximal end 60 and a distal end 61. A flexible removal member 65, e.g. a thread, a string, or a flexible connection, may be arranged at the proximal end 60. More particularly, removal member 65 may also be formed by the fluid duct 5 as described below . As used hereinafter, the term "proximal end" 60 refers to those portions of the assembly and of its components that are situated farthest from the body of a user when tampon-like absorbent body 2 is inserted into a body ori fice , e.g. into the vagina . The term "distal end" 61 refers to those portions of the assembly and of its components that are situated nearest to the body of a user when absorbent body 2 is inserted. Consequently, as used hereinafter, the terms "proximal " or "distal " indicate that a particular part or structure of the assembly or of its components is nearer to proximal end 60 or distal end 61, respectively, of the assembly or of its components . In a similar way, the terms "proximal direction" or "distal direction" refer to the directions toward proximal end 60 or distal end 61 of tampon- like absorbent body 2, respectively. Tampon- like absorbent body 2 comprises an elongated main section having a distal insertion end, a proximal withdrawal end and a middle section 63 extending therebetween .

Furthermore , tampon- like absorbent body 2 has a longitudinal axis 62 and an outer side of an absorbent resp . hygroscopic material . Tampon- like absorbent body 2 or at least the middle section 63 of absorbent body 2 may have a

substantially cylindrical or hollow cylindrical shape that may be a simple geometrical shape of a cylindrical envelope that comes nearest to the overall shape of tampon- like absorbent body 2 or at least of its middle section 63. On its outer side, tampon-like absorbent body 2 may be provided with ribs or grooves , or its outer side may be substantially smooth .

The maximum outside diameter 64 of tampon-like absorbent body 2 or of its middle section 63 may be substantially constant in the longitudinal direction, or it may vary. The portion of tampon-like absorbent body 2 near its proximal end 60 may e.g. have a greater maximum outside diameter than its middle section 63. This thickening at proximal end 60 of tampon-like absorbent body 2 reduces the risk that body liquids may flow out when tampon-like absorbent body 2 is being placed in the vagina .

Tampon-like absorbent body 2 differs from conventional tampons in that the known tampons consist of a solid body of absorbent material. Moreover, the absorbent material is highly compacted, particularly in the area of grooves or indentations .

In contrast thereto, the tampon- like absorbent bodies 2 that are used in connection with a vibration generator 3 have an interior hollow space 66. Accordingly, absorbent body 2 is hood-shaped or hollow cylindrical , at least one of the two front ends of the hollow cylinder preferably being closed by an end wall 67 in the area of distal end 61. Furthermore , the opposite proximal front end 60 may be open or likewise closed by an end wall 68, e.g. by an insert 69 such as a plug . Alternatively, a preferably openable resp . extensible and closable opening may be provided in end wall 68.

The extent of compaction of tampon-shaped absorbent body 2 and thus the mass of fibers 70 and threads 71 to which - Il

liquid may adhere can be selected according to the different embodiments of vibration generator 3. Thus, as in the embodiment illustrated in Figures 1 and 2, the hollow cylindrical tampon-like absorbent body 2 may exhibit a very high inherent rigidity against bending stresses acting transversally to longitudinal axis 62. In this manner, a better transmission of the vibrations , e.g. with a lower attenuation, is advantageously achieved .

On the other hand, however, in the case of vibration

generators 3 formed by bodies whose volume varies , absorbent body 2 may exhibit a certain tensile elasticity at least in the radial direction . To this end, the middle section 63 between the two end walls 67, 68 may preferably comprise weakened or wrinkled portions in the hollow cylindrical envelope that may extend in the longitudinal direction, i.e. in parallel to longitudinal axis 62 of the hollow cyl inder, in the form of grooves or incisions . According to another embodiment variant it is also possible , however, that the weakened areas form radially arranged circumferential zones in a plane extending transversally or obliquely to the longitudinal axis 62 of absorbent body 2.

According to another further development it is also

possible , however, to design absorbent body 2 so as to be capable of an elastic self-recovery when deformed . To this end, elastic threads extending in the longitudinal and/or transverse direc ion relative to longitudinal axis 62 of absorbent body 2 may be incorporated in the material of the absorbent body or integrated into or applied to the inner wall of absorbent body 2 that delimits hollow space 66. It is also possible , however, to provide absorbent body 2 externally with a radially pretensioned, elastically deformable and self-restoring envelope or dome or with rings .

For the manufacture of the assembly of vibration generator 3 and tampon-like absorbent body 2 , vibration generator 3 may be wrapped resp . covered with an absorbent fiber material that forms tampon-like absorbent body 2. Vibration generator 3 may e.g. be sewn into the material of absorbent body 2 or alternatively be prevented from slipping out of absorbent body 2 by the retaining elements mentioned in the

introduction . However, a large number of other measures for connecting vibration generator 3 to tampon-like absorbent body 2 are alternatively possible . Thus , after wrapping vibration generator 3 with tampon-like absorbent body 2 , the proximal end 60 of absorbent body 2 might be tightly

compressed so that this compressed section prevents a withdrawal of vibration generator 3.

Absorbent fiber materials for tampon-like absorbent body 2 may comprise any absorbent materials having acceptable absorbent properties and properties regarding the modulus of elasticity and which are capable of absorbing and/or

retaining liquids . The absorbent structure can be produced in a large diversity of sizes and shapes from a large number of liquid absorbent materials . Of course it is desirable to use absorbent materials having a minimal content of soluble materials as the product is to remain in the body for a certain time period. Foreign substances that are retained may represent a safety risk if they are toxic, irritating or sensitive .

A representative , non-limiting list of suitable materials comprises cellulosic materials such as e.g. rayon, cotton, cellulose , cellulose wadding, tissue , laminated tissue , sphagnum and chemically reinforced, modified, or cross - linked cellulose fibers ; synthetic materials such as e.g. polyester fibers, polyolefin fibers, absorbent foam

materials , e.g. an elastically resilient polyurethane foam, absorbent sponges , extremely absorbent polymers , absorbent gelling materials ; treated fibers such as e.g. capillary channel fibers and multi-limbed fibers ; synthetic fibers or an equivalent material , or combinations of materials or mixtures thereof .

Alternatively, absorbent body 2 may be produced from a synthetic foam material , e.g. a polyurethane foam. This synthetic foam preferably comprises a large proportion of open cells as it is schematically indicated in the sectioned portion of Figure 24. The advantage of using such synthetic foam materials is that when extended, e.g. by the vibrations or by vibration generators consisting of inflatable

elements , they assist the contraction back to the initial position in the radial direction after the extension, i.e. the self-acting elastic recovery, due to their high

elasticities .

If such synthetic foam materials are used, it is also possible, e.g. by adjusting the temperature during the production of the absorbent bodies, to seal the outer skin, i.e. to achieve a closed outer surface in the outer regions due to a partial temperature impact . In this manner, an outflow of liquid absorbed in the foam structure can be further reduced or prevented . Such a structure may be advantageous particularly in the proximal end section 60 of absorbent body 2.

For the purposes of the invention, absorbent body 2 may be produced from the most diverse materials which under the conditions in the area of the vagina res . of the uterus, i.e. at body temperature and a pH value of appro . 4 , remain stable over a prolonged period and do not emit any toxic substances or solutions or the like that might harm the mucosa . Mainly flexible polyurethane foams having a very low volumetric weight and a preponderantly open-celled structure can be advantageously used .

A further advantage of such foam structures is that either in the delivered state or prior to the introduction into the vagina, the open cells can be filled with medicines and/or lubricants that can be released to the mucosa of the vagina resp . of the uterus in the inserted condition. In addition, this release can be assisted by the vibration effect of the vibration generators .

Furthermore it is advantageous if the materials being used are biodegradable and e.g. consist of PLA or other

biodegradable synthetic materials or material mixtures , threads , or fibers . Likewise , housing parts , supporting elements , or guiding elements or also rotating parts of vibration generator 3 and/or of a flow generator 72 may also be formed of biodegradable materials , e.g. of compressed fibers or threads , biodegradable synthetic materials such as PLA, or of recycled synthetic materials such as R-PP, R-PET or the 1 ike , possibly in different mixtures or as multilayer parts from these materials .

In the illustrated exam le according to Figures 1 and 2, vibration generator 3 of tampon assembly 1 comprises a small turbine 13 that serves as drive 73 of vibration generator 3 and will be described in more detail below with reference to Figure 2. To operate turbine 13 , a fluid is supplied thereto by a fluid duct 5 that is advantageously flexible . The other end of fluid duct 5 is connected via a coupling 11 to an energy supply unit 74. In the illustrated exemplary

embodiment , the latter includes an energy source 9, e.g. a current source that may be a battery or a rechargeable battery, for supplying a flow generator 72 that may e.g. be a pump 8. Pump 8 and/or energy source 9 is arranged in a housing 10 and supplies a fluid to turbine 13.

A length 75 of fluid duct 5 between flow generator 72 and housing 10 of energy supply unit 74 is advantageously greater than 20 mm, preferably greater than 50 mm. Usually this length 75 is determined such that energy supply unit 74 and/or flow generator 72 can be attached to a garment , e.g. a slip, or to a panty liner of the user of tampon assembly 1 and a tension-free or loose connection to absorbent body 2 is possible .

Furthermore , in this example , energy supply unit 74 resp . flow generator 72 comprises a pressure container 7. Pressure container 7 may have an arbitrary shape, but it is

preferably in the form of a cylindrical compressed gas cartridge and consists e.g. of metal or a synthetic

material .

The example according to Figure 1 is illustrated as an open system where a gas or a gas mixture is used as the fluid. The expanded gas coming from drive 73 of vibration generator 3 is discharged through an additional fluid duct 6 that preferably ends outside the body of the person who is wearing tampon assembly 1 and releases the gas into the environment . Suitable gases are any gases that are non-toxic for the skin and the mucosa , such as air, C0₂ (carbon dioxide) or N₂0 (nitrous oxide) . In a modification of the embodiment according to Figures 1 and 2 , tampon assembly 1 may al ernatively form a closed system where additional fluid duct 6, rather than opening into the environment , returns the expanded fluid to pump 8 , preferably also via coupling 11. In this case , the fluid may also be a liquid, e.g. water .

In a further modification of the embodiment according to Figures 1 and 2 , pump 8 and energy source 9 may be omitted and pressure container 7 may be so dimensioned that its pressure and content are sufficient for operating drive 73 of vibration generator 3 during a desired time . For

controlling and regulating vibration generator 3, at least one valve that is not shown here may be provided that allows adjusting the quantity and/or the pressure of the pressure fluid being supplied to drive 73 , which in this case is preferably a gas or a gas mixture , in order to vary the frequency and/or the intensity resp . the amplitude of the vibration by means of the valve .

This valve may advantageously be integrated in coupling 11 or connected or connectable thereto . Thus , for example, coupling 11 may include a needle , more particularly a hollow needle , which in order to operate tampon assembly 1 is movable through a thread and pierces a membrane that is e.g. arranged on pressure container 7 , thus allowing the gas flow through fluid duct 5. A releasable coupling 11 of any type is advantageously connected to a nonreturn val e (not shown) resp . to a quick- lock coupling that automatically closes when released or attached, thereby preventing gas from being discharged from pressure container 7 when the latter still contains compressed gas while coupling 11 is being released . Furthermore an embodiment may be contemplated where pressure container 7 is empty in the delivered state and is only filled by means of a pressure generator when needed. The pressure generator may be arranged in housing 10 , as illustrated in Figure 1. Alternatively, however, it may be designed as a stationary unit that is separate from tampon assembly 1 and to which pressure container 7 can be coupled when required in order to be filled. Also, flow generator or pressure generator 72 need not necessarily be a pump but may alternatively be a means generating a pressure , more

particularly a gas pressure , by means of a chemical process , e.g. a small explosive charge as it is known from airbags in transportation means .

Figure 2 shows the tampon of Figure 1 in an enlarged view . The mentioned turbine 13 is received in housing 4. The pressure fluid from the first fluid duct 5 flows through turbine 13 in the direction of arrow 12 , the turbine

rotatively driving a shaft 14 in the direction of arrow 16. A weight 15 is eccentrically arranged on shaft 14 and generates vibrations when rotated . If necessary, a reduction gear may be arranged between shaft 14 and shaft 14 carrying weight 15.

The fluid that has expanded in turbine 13 flows through an exhaust duct 17 in the direction of arrow 18 and leaves tampon-like absorbent body 2 through an additional fluid duct 6. As mentioned, additional fluid duct 6 may end in a location that is situated outside the body of the wearer when absorbent body 2 is being worn as intended . In this case , in order to reduce noise caused by the pressure fluid, here a gas , the free end of additional fluid duct 6 may be provided with a silencer 76 (see Figure 1 ) . Fluid duct 5 and additional fluid duct 6 are preferably in the form of flexible tubes . The latter may also be combined in a two- chamber tube as they are commercially available .

Alternatively, each tube may be designed as a spiral tube .

In contrast to the illustrations of Figure 1 and 2 , where vibration generator 3 is arranged in a hollow space 66 inside absorbent body 2 , Figures 3 and 4 show possible exemplary arrangements of vibration generator 3 on tampon- like absorbent body 2.

In this embodiment , absorbent body 2 is provided with a passage for fluid duct 5. According to Figure 2, an

elastically extensible and self-restoring balloon-like expansion body acting as a vibration generator 3 is held resp . supported in the area of the distal end of absorbent body 2. Embodiments of such an expansion body are

illustrated in Figures 14 , 19, and 20. The expansion and contraction of the expansion body may be achieved by del iberate positive and negative fluid impulses resp .

pressure pulses , e.g. by supplying a pressure fluid and releasing the pressure fluid, possibly accompanied by the creation of a vacuum in the interior of the expansion body, or sup lied pressure pulses , whereas the recovery and the recirculation of the fluid from expansion body 78 may be achieved by the restoring force resulting from the elastic self-acting recovery of the balloon of expansion body 78 to its initial position. Expansion body 78 rests on distal end 61 resp . on the recess in absorbent body 2.

Figure 4 shows a similar arrangement as Figure 3 , however with a vibration generator according to Figure 9.

Figure 5 shows another embodiment of vibration generator 3 in a hollow space 66 of an absorbent body 2. In a housing 21 , a hollow space and fluid ducts are arranged such that a body 19 arranged in the hollow space is spun around in the direction of arrow 16 by a fluid flow (arrow 22) entering into the hollow space . Body 19 may e.g. be a ball or a cylinder . The forces transmitted to housing 21 during the movement of body 19 along the inner wall of the hollow space cause the housing to vibrate . The fluid leaves the hollow space in the direction of arrow 23. In the exemplary embodiment of vibration generator 3

illustrated in Figure 6, a rotation-asymmetrical body 20 is mounted freely rotatably on an axle 24 in the hollow space of housing 21 according to Figure 5. When a pressure fluid flows against body 20 according to arrows 25 , the latter will be set into rotation according to arrow 16 and produce vibrations due to its imbalance . The surface against which the fluid flows may be inclined relative to axle 24. A substantial advantage of this embodiment is that both the actuation and the vibration generation are achieved by one and the same body 20.

The embodiment of vibration generator 3 illustrated in

Figure 7, which may be incorporated in a hollow space 66 of an absorbent body 2, is based on an assembly of a cylinder 28 and a piston 27 that is displaceable therein by fluid pressure . Piston 27 has ducts arranged such that in the position of piston 27 shown in Figure 7, the fluid flowing in according to arrow 22 is led into the closed space above piston 27 , whereby piston 27 is pressed down against the force of a spring 29. During this downward movement of piston 27 , the duct that supplies the pressure fluid is closed and a duct that discharges the pressure fluid

according to arrow 23 is opened so that piston 27 is moved upwards by the force of spring 29. Therefore, piston 27 can move up and down according to double arrow 26 and thus produce a vibration .

A similar arrangement as in Figure 7 is shown in Figure 8 where a piston 27 is again movable back and forth in a cylinder 28 according to a double arrow 26 and thus produces vibrations . In operation, the fluid flows through a tube 34 in the direction of arrow 22 , the tube ending in a recess 35 in piston 27. By the fluid pressure, piston 27 is moved to the left in the figure against the force of a spring 33 until piston 27 has reached a position in which tube 34 no longer enters into recess 35 in piston 27. The fluid now flows past piston 27 into cylinder 28 and leaves the latter in the direction of arrows 23 until piston 27 is moved back towards tube 34 by the force of spring 33. The rhythmic repetition of this piston movement produces vibrations . This vibration generator 3 with its cylinder 28 may also be inserted in a hollow space 66 of absorbent body 2. It is also possible , however, that e.g. spring 33 is

directly arranged in hollow space 66 of absorbent body 2 and movable piston 27 also moves inside this hollow space 66. Instead of a thick cylinder wall of cylinder 28 it is also possible, however, to ensure the required pressure

resistance for the guidance of movable piston 27 by a very thin outer wall of cylinder 28 that is supported by the compacted areas of absorbent body 2.

The following Figures 9 to 13 show vibration generators 3 that may be inserted in a hollow space 66 of an absorbent body 2 of tampon assembly 1 , possibly in a housing .

Figure 9 shows a further embodiment of a vibration generator 3 where again a fluid is supplied according to an arrow 22 and flows off in the direction of an arrow 23. A spring 33 arranged in a housing 36 biases a ball 37 towards a seat so that ball 37 blocks the inflow of fluid. As the fluid pressure in the inlet duct increases , ball 37 is lifted off from its seat, whereby the pressure of the inflow again decreases . This sequence is rhythmically repeated and produces vibrations that are transmitted to absorbent body

2. Figure 10 shows another embodiment of vibration generator 3. A body 30 is fastened to a spring 31 inside a space . When a fluid flows into the space in the direction of arrow 22 and leaves the space in the direction of arrow 23 , this will cause body 30 to oscillate in the direction of double arrow 26, which is already perceived as a vibration by itself . In the case of stronger excursions, the body will strike the inner wall of the space , thereby increasing the vibrations .

The vibration generator 3 according to Figure 11 is based on a flexible tube 39 one side of which is fixed in a housing 38 and through which a fluid under pressure is supplied according to arrow 22. The outflowing fluid causes random movements of the free end of tube 39 in the manner of a water hose that is loose . The fluid leaves housing 38 in the direction of arrow 23. To amplify the vibrations produced by the movements of the free end of flexible tube 39 , the free end of flexible tube 39 may be provided with an additional weight 40. Also, the individual components may be so

designed that the free end of flexible tube 39 and/or weight 40 arranged thereon strike housing 38 in their movements and thus amplify the vibration impulses.

Figure 12 shows a further embodiment of vibration generator

3 that is particularly suitable for being operated by a gas or a gas mixture . A gas flow entering into a space according to arrows 25 causes a lamella 32 arranged at the exit of the space to oscillate in the direction of double arrow 26. It is also possible to make lamella 32 oscillate by a gas flowing in the opposite direction, similarly to the

operation of a woodwind instrument . The vibrations are produced by the oscillations of lamella 32 and its impacts on the wall that delimits the space .

Figure 13 shows a special embodiment of a vibration

generator 3. In a housing 41, a space filled with a liquid 43 is limited by two membranes 42 that are permeable to gases but not to liquids . When a gas is supplied according to arrow 22 , bubbles 44 are created in liquid 43 which produce vibrations similarly as it is known from whirlpools . After its passage through liquid 43 and membrane 42 arranged on the left in the figure, the gas is discharged in the direction of arrow 23.

Figure 14 shows a schematic illustration of a further embodiment of a tampon assembly 1. In tampon-like absorbent body 2, a vibration generator 3 of a very simple design is arranged which consists of a balloon-like, rubber-elastic expansion body 78 and rhythmically expands and collapses due to a pulsating fluid. For this purpose , only a single fluid duct 5 is required which is connected to a pump 8 arranged in a housing 10 , preferably by an easily releasable coupl ing 11. Alternatively, coupling 11 might be arranged on the side of tampon 2. In the depicted example , pump 8 is supplied with electric energy by a current source 9. Since this is a closed system, a liquid can be used as the fluid .

Furthermore, a liquid is advantageous in this embodiment as it provides a better transmission of pressure pulses from pump 8 to vibration generator 3 than a gas due to its incompressibility .

In some tampon-like absorbent bodies 2 it is advantageous if the resistance against a deformation of absorbent body 2 in the radial direction is lower than the expansion force acting due to vibration generator 3 in the radial direction . The recovery of the absorbent body or of parts of the absorbent body that are deformed by the radial force, respectively, may be achieved by a restoring force that is produced by vibration generator 3, e.g. by the action of a vacuum. To this end, there is advantageously a motional connection to absorbent body 2 or to movable parts of absorbent body 2, respectivel . However, as will be

explained in detail below with reference to the embodiments according to Figure 22 , it is also possible to design the absorbent body in such a manner that absorbent body 2 or movable or deformable parts of absorbent body 2 produce an elastic self-recovery.

This may be achieved by restoring elements that are

incorporated in absorbent body 2 , wrap around the latter or are connected thereto, such as tensioning elements 91

(Figure 22) , elastic threads , inserts or sheaths which produce self-acting elastic restoring forces in the radial direction. Usually, these restoring forces should be

dimensioned so as to be smaller than the radial expansion forces of vibration generator 3 but greater than the

resistance of vibration generator 3 , more particularly of an expansion element that is expansible by a fluid, during the recovery to its relieved initial position .

In this regard it may be advantageous if the restoring force is so dimensioned that e.g. the fluid contained in the expansion body, more particularly a gas such as air, is discharged to the free atmosphere or to a pressure- free tank . Three further embodiments of vibration generators 3 are illustrated in Figures 15 to 17 and are also suitable for use in a tampon assembly 1 according to the invention. To this end, at least a part of absorbent body 2 has to be incorporated into hollow space 66. A piston 46 is imparted a reciprocating movement according to double arrow 26 in a cylinder 45 by a pulsating fluid supplied by means of a duct 5 according to double arrow 49.

In the embodiment according to Figure 15 , on the side of piston 46 opposite fluid duct 5 , a closed space 47 is provided which is advantageously filled with a gas that acts on piston 46 like a spring . Alternatively, according to Figure 16 , space 47 may contain a spring 48 acting on piston 46. In this case it is advantageous if space 47 communicates with the environment through a small opening (not shown) to avoid the formation of an unwanted fluid cushion .

In the embodiment according to Figure 17 , space 47 is connected to additional fluid duct 6 which, as described above , may open into the environment or lead back to pump 8.

In the embodiment according to Figure 18 , instead of a

piston, an elastic membrane 50 that separates space 47 is provided. The membrane supports an additional weight 51 in order to amplify the impulses of the vibrations .

Vibration generators 3 according to Figures 19 and 20 are based on elastic hollow bodies 52 and 55 , respectively, that may be directly embedded in a tampon- like absorbent body 2. They are also intended to be actuated by a pulsating fluid pressure according to double arrow 49. Hollow body 52 according to Figure 19 includes a corrugated portion 53 that performs a rhythmic expansion and contraction in the

longitudinal direction according to double arrow 54 under the action of a fluid with a pulsating pressure . Hollow body 55 according to Figure 20 has circumferential portions 56 of reduced wall thickness so that these portions 56 expand and contract in the direction of double arrows 57 when a fluid pressure is applied .

A further embodiment variant is shown in Figure 21. In this embodiment variant , absorbent body 2 of tampon assembly 1 has a hood- shaped configuration and its distal end 61 with end wall 67 is dome-shaped, e.g. in the shape of a spherical calotte or of a conical section with a rounded ape . In the opposite area of proximal end 60, absorbent body 2 may be provided with closure lobes 80, 81 proj ecting towards its longitudinal axis that are outwardly deformable to such an extent that they approximately extend in the longitudinal direction of the longitudinal wall of hollow cylindrical middle section 63 of absorbent body 2, as indicated by dotted lines. In this manner, a hollow space 66 is created in absorbent body 2 that is accessible from the exterior by closure lobes 80 and 81.

A vibration generator 3 , possibly together with a flow generator 72 , can thus be inserted in this hollow space 66 and fastened therein . This fastening may be achieved by proj ections or anchoring members arranged on the housing of vibration generator 3 and/or of flow generator 72 or, as schematically indicated on a portion of hollow space 66 , by a Velcro strip 82 , or alternatively by bonding .

Alternatively it may be sufficient if the proximal end wall 60, as indicated in the area of closure lobe 80 , is

completely closed after the insertion of vibration generator 3 and/or flow generator 42 by means of a disk 83 , e.g. from a foil , so that the components arranged in hollow space 66 are also fastened.

This disk 83 , which may have a passage for at least one duct 5 , 6 , may e.g. be formed of an aluminum foil , a piece of fabric or knit fabric, or a plastic film, which may be connected to end wall 60 by bonding, hot sealing or the like.

In the present case, absorbent body 2 has a uniform wall thickness 84 , 85 in its middle section 63. However, the wall thicknesses 84 , 85 may vary over the circumference in order to allow different degrees of deformation of absorbent body 2. In the present case, absorbent body 2 consists of threads and/or fibers 70 , 71 , as schematically illustrated in a part thereof .

When a vibration generator 3 as e.g. described with

reference to the foregoing Figures 1 and 2 and 5 to 13 is inserted, it is advantageous if absorbent body 2 is very highly compacted and allows a relatively low elastic

deformation in the radial direction, i.e. of the wall thicknesses 84 , 85 , during the vibrations produced by vibration generator 3. In this manner, the vibrations produced by vibration generator 3 are transmitted to the neighboring body parts of the user with a relatively low amplitude loss .

Above all it is advantageous if in middle section 63 the elastic deformability of absorbent body 2 with regard to a reduction of its wall thickness requires a higher force expenditure than the radial force component produced by vibration generator 3. As the case may be, however, it can also be advantageous if the radial force produced by vibration generator 3 is slightly greater than the

deformation force in the direction of wall thickness 84 and 85 of absorbent body 2 as under certain circumstances an elastic recovery and movement of the outer surf ce and of the outer layers of absorbent body 3 relative to the adj acent body parts may thus be achieved in a certain region. This may be helpful for the delivery of medicines, gels , or liquids provided in parts of the surface of absorbent body 2 or also for an improved uptake of body fluids from the directly adj acent body parts or for drawing body fluids from the interior of the body into the region of absorbent body 2.

According to one variant of the present embodiment , when the radial forces of vibration generator 3 are e.g. situated near proximal end 60, as indicated by dotted lines , e.g. several weakened portions , i.e. in which a wall thickness 87 is smaller than in the neighboring areas , extending in the direction of longitudinal axis 62 may be distributed over the circumference of absorbent body 2. In this manner it is possible that absorbent body 2 is more elastic towards its proximal end 60 and that the individual elements of

absorbent body 2 , as indicated by dotted lines also, may yield and vibrate , e.g. during the vibration movement , in order to thus transmit vibrations of a higher amplitude to the body. Furthermore , this excursion of the side walls of cylindrical middle section 63 of absorbent body 2

facilitates the integration of vibration generator 3 or flow generator 72 , respectively . In this case it may be

advantageous to omit the disk for the closure of hollow space 66 or to manufacture it from a very easily extensible material .

Figures 22 and 23 illustrate a further embodiment of the tampon assembly according to the invention . In absorbent body 2, several hollow spaces 66 are arranged which are distributed over its circumference and extend in the direction of longitudinal axis 62 of tampon assembly 1 in a tubular shape . Hollow spaces 66 are arranged between

longitudinal axis 62 and the outer side of middle section 63 of absorbent body 2. Hollow spaces 66 may also be connected to form a common hollow space . In each of these hollow spaces 66 , tubular expansion bodies 78 are supported on a highly compacted inner part of absorbent body 2 or on one another .

In this case, a pulsating fluid is supplied to tubular expansion bodies 78 incorporated in these very slim hollow spaces 66. To this end, each hollow space 66 can be supplied with the fluid by a fluid duct 5 separately . Alternatively thereto, the fluid may flow through hollow spaces 66 in direct succession or in different orders , e.g. also in an overlapping manner . Whenever fluid is inj ected, expansion body 78 expands . As a result , the portions of absorbent body 2 having a smaller wall thickness 87 , as indicated by dotted lines, are outwardly deformed by a distance 89.

This deformation may be further assisted in that adj acent to hollow spaces 66 , weakened portions , i.e. channels or grooves 90 are provided, as shown in the top view of Figure 23. The recovery of these elements resp . of the wall

portions of absorbent body 2 can be achieved by the

corresponding application of a sufficient negative pressure via fluid duct 5. Alternatively, as indicated by dotted lines also, the recovery may be achieved by elastic

tensioning elements 91, e.g. incorporated rubber threads or rings or other elastic tensioning means . In this manner it is only necessary to supply expansion bodies 78 with pressure medium impulses whereas the compression of

expansion bodies 78 and the ej ection of the fluid from their interior is achieved by tensioning elements 91 through a self-acting elastic recovery of absorbent bodies 2. It is e.g. also possible, inter alia, to compact those portions of absorbent body 2 particularly strongly where no channels or grooves 90 or portions of smaller wall thickness 87 are provided in order to achieve a high absorption capacity for liquids, on one hand, and furthermore a high stiffness , so that a directed expansion of the flexible portions of absorbent body 2 is enabled.

In Figure 24 an embodiment variant is depicted where

absorbent body 2 of tampon assembly 1 is formed by an open- celled foam, more particularly an open-celled synthetic foam 92 , or a foam- like rubber body, as symbolically indicated in a part of the hatched area . In this case , hollow space 66 provided inside absorbent body 2 can be closed by a closure cap 93 that is integrally formed directly on middle section 63 of absorbent body 2 after the introduction of vibration generator 3 resp . flow generator 72. To lead through at least one duct 6, a slot is provided in closure cap 93.

Furthermore it is shown in this exemplary embodiment that when an expansion body 78 is used as vibration generator 3, in addition to weakening the wall thickness , wall thickness 84 , 85 may be reduced to a smaller wall thickness 87 in at least one , preferably more areas that are spaced apart and distributed over the circumference of absorbent body 2. This may be achieved by the partial formation of grooves 90 formed on part of the thickness of absorbent body 2 and proj ecting from the outside toward longitudinal axis 62. In addition, in order to achieve a higher elasticity, the hollow cylindrical middle section 63 may be sectioned or cut in order to attain an ever higher flexibility.

Advantageously, by using a foam-shaped absorbent body 2 , a higher moisture absorption can be achieved. In addition, a higher suction can be achieved by the pulsating

pressurization of the foam . It is understood, however, that it is also possible to operate absorbent bodies 2 according to Figures 21 to 24 with vibration generators 3 according to Figures 1 , 2 and 5 to 13 and 15 to 18. However, they are also advantageously used in combination with vibration generators 3 as they are depicted in Figures 14 and 19 resp . 20.

Figure 25 schematically shows the placement of a tampon assembly 1 in the region of the vagina . Fluid ducts 5 and 6 leading away from the proximal end 60 of tampon assembly 1 are schematically indicated and in the present example extend between a body surface 94 and a garment, e.g. a slip 95. Of course it is also possible that fluid duct 5 or fluid duct 5 , 6 is incorporated into slip 95 or arranged on the side of slip 95 facing away from body surface 94. To this end, slip 95 may also be provided with corresponding

openings or apertures .

On slip 95, advantageously in the region of an elastic band or on a fabric part of slip 95 , a housing 10 may be attached e.g. by means of Velcro strips or other closure or snap elements , in which energy supply unit 74 and possibly flow generator 72 may be arranged . It follows that the length 75 of fluid ducts 5 , 6 should be adapted to the corresponding garments and more particularly to the manner in which housing 10 with energy source 9 resp . flow generator 72 is fastened . Therefore it may be advantageous to realize fluid ducts 5 , 6 as highly flexible spiral ducts for different applications . On the other hand, however, it is also possible to preequip the garments with fluid duct 5 , 6 in a corresponding manner so that only energy source 9 and housing 10 , possibly together with flow generator 72 , need to be connected on one side, and absorbent body 2 with vibration generator 3 at the other end.

Therefore , the length of fluid duct or fluid ducts 5 , 6 may be comprised between 20 mm and 150 mm, preferably between 20 mm and 100 mm - depending on the size of the garment , more particularly of slip 95.

Advantageously, the fluid ducts are dimensionally stable in the radial direction but extensible in the longitudinal direction. In this manner, an adjustment to the different desired lengths is easily obtained .

The individual embodiments depicted in the figures can also form the subj ect matter of independent solutions according to the invention . The obj ectives and solutions according to the invention relating thereto can be taken from the

illustrated but instead the individual variants may be used in different combinations with one another and these

possible variations lie within the reach of the person skilled in this technical field given the disclosed

technical teaching . Accordingly, all conceivable embodiment variants which can be obtained by combining individual details of the embodiment variants described and illustrated are possible and fall within the scope of the invention .
