Description

Treatment head for gynaecological and hygienic devices

The subject of the invention is a treatment head for gynaecological and hygienic devices, which is suitable for intake of medication for the efficient and careful hygienic and therapeutical treatment of the vagina.

Circulating douches to be joined to the tap have been widespread since the early 1940s. Their basic characteristics is, that the medication, the active material was sent to the place of healing with a suitable device with mixing with tap water of drinking water quality. Different versions of these devices have been formed as the techniques developed and the range of raw materials to be used widened.

In the state of the art there are various solutions to treat locally gynaecological problems. One of the well-known wide-spread devices is the douche with pump, suitable to put the treating solution of healing effect, mixed in advance to the place of treatment. The drawback in this case is the risk of infection, as the pump could suck back the liquid already discharged, and in case of inappropriate cleaning of the device there is the danger of infection again. Another disadvantage is, that only 1-2 dl liquid could be squeezed out, so the cleaning effect of such stream is moderate.

In the state of the art a cleaning device is described in patent US 6 156 017. It can be used for personal hygiene, can be joined to the shower-head directly. The device has a streamlined house, that can be directly connected to any ordinary shower joint. This house has an end, which can be rotated. The house has a flow-leading pushing element placed in the connecting part.

The deficiency of the solutions in the state of the art and those generally used is, that they do not properly protect the human organism from unpleasant effects. The well- known devices are provided with a smooth surface and perpendicular discharging openings for the rinsing water. Therefore during douche unwanted overpressure is produced within the vagina, especially near the cervix. In given case it involves spread of the bacterial infection in the vagina resulting in the increase of risk factor of inflammations in the small pelvic. An additional drawback of the well-known devices of smooth surface is, that there is no back-flow duct on their surface in any of the cases, which might result in the blowing up of the vagina in case the muscles of the bar close.

When working out the solution according to the invention we aimed to create a material of hygienic purpose and healing effect as well as a device suitable for use as a healing auxiliary, which has a form suitable for appropriate douching of the vagina in households provided with tap water, in given case suitable for the intake of multiple active materials, furthermore it is of safe and well- thought out structure.

When working out the solution according to the invention we realized, that in case a treating head of lengthwise form, slightly arched and curved can be shaped, and at one end of the treatment head there is a joining part, at the other end there is a rounded tip, and the treatment head has lengthwise exterior flow ducts connecting to the joining hollow of the joining part and has an interior flow duct connecting to the joining hollow as well, and discharging openings formed on the outer surface of the treatment head join the flow ducts and furthermore there is a back-flow duct in the bottom of the treatment head, then the set aim can be achieved.

The invention is a treatment head for gynaecological and hygienic devices, which has flow ducts and discharging openings for circulation of liquid, which is characterized by that, there is a joining part at one end of the lengthwise, slightly arch-like, curved treatment head and there is a rounded tip at the other end, and the treatment head has lengthwise exterior flow ducts connecting to the joining hollow of the joining part, and has as well an interior flow duct connecting to the joining hollow as well, and discharging openings formed on the outer surface of the treatment head join the flowing ducts and furthermore there is a back-flow duct in the bottom of the treatment head.

In a preferred embodiment of the treatment head according to the invention the discharging openings of the exterior flow duct are formed on the outer surface of the treatment head between the half and the one-fifth of the length of the treatment head, whereas the discharging openings of the interior flow duct are formed near the tip of the treatment head.

In a further preferred embodiment of the treatment head according to the invention the discharging openings starting from the exterior flow ducts are formed in the lengthwise grooves slantwise/at an angle to the radius, preferably in the direction of the tangent of the lengthwise ribs running beside them.

In a further preferred embodiment of the treatment head according to the invention the discharging openings of the interior flow duct are formed in the direction of the factor of the cone-mantle, in the direction of the lengthwise grooves.

In a further preferred embodiment of the treatment head according to the invention the back-flow duct formed in the bottom of the treatment head is bordered with brims on the side and ends in front of the conical neck of the joining part with an outlet surface.

In a further preferred embodiment of the treatment head according to the invention the exterior flow duct joins preferably the inflow groove formed in the bottom of the joining hollow in the inside of the joining part, whereas the interior flow duct preferably joins the interior joining stump protruding into the middle of the joining hollow in the inside of the j oining part.

In a further preferred embodiment of the treatment head according to the invention the treatment head is formed preferably with a bayonet-joint joining part and joins a device dispensing active material or medication. In a further preferred embodiment of the treatment head according to the invention the joining eyes of the connection with bayonet joint are formed in the inside of the joining part, furthermore a sealing ring nest is formed in the bottom of the joining hollow. hi a further preferred embodiment of the treatment head according to the invention the material of the treatment head is injection moulded plastic, preferably polyethylene, polypropylene, made by injection moulding.

One of the exterior flow ducts 5 placed lengthwise in the treatment head 1 can be seen in section in Fig 1, as well as the interior flow duct 6. The exterior flow duct 5 joins the inflow groove 14 formed in the bottom of the joining hollow 3 in the inside of the joining part 2. In given case the interior flow duct 6 joins the interior joining stump 10 protruding into the middle of the joining hollow 3 in the inside of the 2 joining part 2. Furthermore the joining eye 11 of the connection with bayonet-joint is in given case formed in the inside of the joining part 2.

The discharging openings 12 of the exterior flow duct 5 are formed on the outer surface of the treatment head 1 relating from the tip 4 between the half and one-fifth of the length of the treatment head 1. The discharging openings 13 of the interior flow duct 6 are formed at the tip 4 of the treatment head 1, at a 120°angle to the axis of the treatment head 1. In the bottom of the treatment head 1 is formed the back-flow duct 7 bordered with brims 8, 9 with rims folding back, ending with outlet surface 16 in front of the conical neck 15 of the joining part 2. The task of the back-flow duct 7 is to ensure safe disposal of the liquid in the vagina, even if the vagina walls or bar stretch on the outside surface of the treatment head 1. The back-flowing liquid is led from the back-flow duct 7 to the outer space by the outlet surface 16.

Fig 2 shows the cross-section of the treatment head 1 according to the invention in the A section of the form to be seen in Fig 1 near the joining part 2 of the treatment head 1. hi the Figure the four pieces of exterior flow ducts 5 can be seen in section, as well as the interior flow duct 6 running in the middle, as well as the back-flow duct 7 formed in the bottom of the treatment head 1 bordered with brims 8, 9 with rims folding back.

The figure furthermore shows the inflow groove 14 formed in the bottom of the joining hollow 3 connecting to exterior flow ducts 5 as well as the sealing ring 19.

The interior joining stump 10 makes possible to send active materials of different composition through exterior flow ducts 5 and interior flow duct 6 depending on the dispensing device applied. It makes possible as well, that dispensing of the active material take place in different length of time and composition in different parts of the treatment head 1. Fig 7 shows the joining part 2 from top view. The exterior flow ducts 5 starting from the bottom of the joining hollow 3 of the joining part 2 can be seen in the figure, as well as the ulterior flow duct 6 starting from the ulterior joining stump 10. Furthermore the joining eyes 11 resulting from the bayonet-joint as well as the inflow groove 14 formed in the bottom of the joining hollow 3 and the sealing ring nest 19.

The application and functioning of the treatment head 1 according to the invention is as follows:

The treatment head 1 according to the invention is of lengthwise, slightly curved form and in its inside there are five pieces of flow ducts 5,6 as well as a back-flow duct 7 open towards the exterior. The cross-section of the treatment head 1 is such, that there are ribs 17 and grooves 18 on the outer surface of the exterior flow ducts 5. They are formed to hinder locking and partly to ensure free outflow. The lower back-flow duct 7 runs lengthwise in the bottom of the treatment head 1 and is open downwards. The back-flow duct 7 is bordered from the side by brims 8,9 folding back.

On the exterior surface of the treatment head 1 there are lateral discharging openings 12,13 joining each flow duct, in given case three pieces each duct. The discharging openings 13 of the interior flow duct 6 running in the middle, are formed at the end of the treatment head 1, and are situated along a cone-mantle in 120°angle each slantwise towards the exterior. The diameter and calibration of discharging openings 12,13 ensure uniform pressure of discharging liquid.

In case of intake of active materials of multiple phase, the task of the middle interior flow duct 6 is double, in the first, rinsing phase ensures discharge of the solution containing the active material, whereas in the second, post-treatment phase it ensures intake of gel-like active material.

The exterior flow ducts 5 have a role in the rinsing phase only, as the water-soluble active material flows through these together with the water and flows out slantwise, laterally to the axis of the treatment head 1 and those of the flow ducts 5. The reason for this is, that the exterior ribs 17 of the treatment head 1 tighten to the inner wall of the vagina, or touch them. So discharge of the water in perpendicular direction is more difficult, limited, because the tissues would block this discharging direction. The formation of the lateral discharging openings 12 ensure, that the liquid discharging from the treatment head 1 comes to the grooves 18 next to the rib 17, from where it flows further to the possible directions.

On the surface of the treatment head 1 the angle of the discharging opening 12,13 ensures, that inside the vagina there is a certain spiral flow of liquid, resulting in the appropriate rinsing and washing effect. The liquid in the inside of the vagina is discharged between the ribs 17 and through the back-flow duct 7.

In case of a possible embodiment of the solution according to the invention the shape and measurements of the treatment head 1 conform with the anatomical shape of the vagina. The length of the treatment head 1 is in given case 10-15 cm, its diameter is 2-4 cm. The material of the treatment head is injection moulded plastic, preferably polyethylene, polypropylene, or other organism-friendly medically approved plastic. In case of given form each flow duct 5,6 has three discharging openings 12,13 and they are placed hi case of exterior flow ducts 5 between the half and one-fifth of the length, spaced out evenly, whereas at the ulterior flow duct they are sectioned near the tip 4, along the factors of a cone-mantle spaced out hi 120° angle.

The advantage of the solution according to the invention is that the measurement of all the openings is calibrated so, from safety point of view, that the liquid can be discharged from the vagina without overpressure through the safety flow-back duct along the ribs. It is important, because all the other devices have smooth surface and perpendicular discharging openings and works by creating an overpressure within the vagina, especially at the cervix. It involves spreading of a bacterial infection and results hi the increased risk factor of inflammations in the small pelvic, hi case of the other devices of smooth surface none of the cases can we find a back-flow duct.

The joining end of the treatment head according to the invention is provided with a bayonet-joint and the flow-ducts are formed in a way, that the exterior four flow-ducts are formed to receive and forward only the rinsing liquid and the flow-ducts are connected with a common inflow groove 14. The middle flow-duct is in the middle axis of the joining end of the treatment head 1 and it is preferably provided with an ulterior joining stump, which makes possible the intake different from other devices.

The advantage of the treatment head according to the invention is, that it makes possible the intake of an active material of two phases, as the intake ducts - the exterior 4, and the middle fifth — can be fed separately from each other. But the treatment head can be operated as a douche head hi case of an active material of one phase. At the joining stump of the treatment head an O ring is placed for the sake of safe locking, which separates the middle flow duct from the exterior flow duct 4.

A further advantage of the solution according to the invention is, that it promotes the intake of medications in simple, efficient way. The slightly curved form of the douche head conforms with the anatomical shape of the vagina, so its introduction and application do not cause any inconvenience or discomfort.
