Abstract

A non-invasive penile erection device has a constricting ring designed to abut the base of a male genitalia or penis and a diaphragm seal forming a substantially air-tight seal against the constricting ring. The constricting toroid is designed to comfortably and reliably engage the base of the penis. The substantially air-tight seal allows the pump to generate a vacuum pressure in excess of 17 inches of mercury. The constricting toroid is placed at the base of the penis and the greater vacuum pressure achieved by the device draws the base of the penis into the constricting toroid, so that a more natural erection is achieved and maintained after the vacuum tube is removed.

Description

penile erection device

The utility model relates to a non-invasive penile erection device.

There are a wide variety of non-invasive, vacuum-type penile dilatation devices available on the market. These expansion devices use external vacuum pressure to replace the body's natural ability to inflate the male genitalia or penis. These devices generally utilize a cylindrical vacuum tube to accommodate the penis, a diaphragm to seal the open end of the vacuum tube around the penis, and a pump to evacuate or remove air from the vacuum tube. When the air is removed from the tube, the reduction in pressure causes blood to enter the penis and cause it to expand. After dilation of the penis, a constriction ring is generally placed around it to maintain the dilation of the penis when the vacuum is removed. These devices are shown in U.S. Patent No. 4,641,638 to Perry, U.S. Patent No. 4,753,227 to Yanuck Jr., U.S. Patent No. 4,856,498 to Osbon, U.S. Patent No. 5,125,890 to Merrill, and U.S. Patent No. 5,344,389 to Walsdorf Examples, the contents of which are incorporated by reference.

A disadvantage of conventional penile dilatation devices is that the diaphragm does not form a sufficiently airtight seal to generate the desired amount of vacuum pressure within the tube. Even when a gel lubricant is applied to the diaphragm and penis to improve the seal, air can leak between the diaphragm and the penis. This air leak reduces the amount of vacuum pressure achieved within the tube, as well as the amount of expansion and firmness of the male genitalia. The conventional penis expansion device reaches about 14 to 16 inches of mercury column vacuum pressure, and fully inflated, the effective erection usually requires about 17 to 22 inches of mercury column vacuum pressure.

Another disadvantage of the prior art is that the expansion device does not expand and maintain the penis in an erect and coaptive position. Conventional shrink rings are designed to fit over and secure to the actual flat shaft portion of the penis. The rings are not intended to fit around the base of the penis, which is of increasing diameter, located against the groin of the individual, especially when inflated. The widening of the base creates an incline that causes the constriction ring to slide off the base and onto the shaft of the penis. Conventional constriction rings are also not designed to allow the root of the penis protruding into the individual's groin to be drawn into the constriction ring. When the vacuum tube is removed, only the portion of the penile shaft downstream of the constriction ring remains inflated. The base and root of the penis remain or return to a weak state, and the penis cannot reach and maintain the natural erection position.

A further problem with the prior art is that the weak base and root of the penis upstream of the constriction ring create a "joint" around which the inflated shaft portion may bend. Manipulation of the inflated part of the penis must be done by hand, which may be particularly difficult for paraplegics and quadriplegics or their spouses.

Another problem with the prior art is that the known constriction rings used in various expansion devices are painful due to their narrow width and generally "rubber-like" shape. The edge of the constriction ring pokes into the individual's skin and causes considerable pain.

A further problem with known designs is the difficulty in positioning the constriction ring at the base or root of the male genitalia after it is placed on the penis. The user must grasp the edge of the narrow rubber-like constriction ring to adjust the constriction ring and try to maneuver it to the base after it is initially placed on the shaft of the penis. This is difficult when the edge of the constriction ring is poked into the skin.

Another problem with conventional designs is that the lubricant used to help form the seal between the diaphragm and the male genitalia becomes dirty. The lubricant must be spread throughout the expansion device, the individual's hands and body, and surrounding clothing.

Yet another problem with the prior art is that the diaphragm and shrink ring do not fit all individuals with equal comfort and equal effect. Different individuals require different sizes of shrink rings and diaphragms. The trial and error method of obtaining the correct size shrink ring and diaphragm can be inconvenient and embarrassing given the nature of the products involved.

Another problem with prior art components is that manufacturing costs can be prohibitive. The cost and number of components making up the penile erection device should be kept to a minimum. Erectile devices should also work with existing vacuum tube and pump designs where possible to avoid costly and time consuming manufacturing modifications.

The present work is provided to solve these and many other problems.

The purpose of this utility model is to provide a non-invasive penile erection device, which can make the contraction ring close to the base of the male genitalia or penis, and seal with a diaphragm to form a practical airtight seal against the contraction ring. The shrink ring is designed to fit comfortably and securely around the base of the penis. The virtually airtight seal enables the pump to generate a vacuum pressure of 17 inches above mercury. The placement of the constriction ring at the base of the penis, and the greater vacuum pressure achieved by the device, will draw the root of the penis into the constriction ring, resulting in a more natural erection after removal of the vacuum tube.

The technical scheme of the utility model is:

A penile erection device comprising a vacuum tube having an open end and an interior suitable for receiving a male genitalia; characterized in that it also includes

a flexible diaphragm seal having an inner end and an outer end that seals around the open end of the vacuum tube; and

A constriction ring is placed over the male genitalia, and the diaphragm-sealed inner end is sealed around the constriction ring.

The penile erection device is characterized in that the diaphragm abuts and seals around the male genitalia before vacuum pressure is applied to the interior of the vacuum tube, and the contraction ring seals against the diaphragm when vacuum pressure is applied to the interior of the vacuum tube.

The penile erection device is characterized in that: the diaphragm has an outer and inner surface, and wherein when a first predetermined amount of vacuum pressure is reached in the vacuum tube, the inner surface of the diaphragm abuts against the constriction ring and reaches a second predetermined amount in the vacuum tube. When a certain amount of pressure is applied, the diaphragm inverts to form an "S" shape and the outer surface of the diaphragm seals against the shrink ring.

The penile erection device is characterized in that: the contraction ring has an inner surface and inner and outer ends, and the outer end has an inner surface with a predetermined diameter, and the inner diameter continuously increases from the outer end to the inner end.

The penile erection device is characterized in that: the constriction ring has a tapered portion located near the inner end of the constriction ring, and the constriction ring has a tubular portion located near the outer end of the constriction ring.

The penile erection device is characterized in that: the inner and outer ends of the inner surface of the contraction ring are circular, and wherein the contraction ring has an outer surface, and the outer end of the outer surface of the contraction ring is circular.

The penile erection device is characterized in that: the constriction ring includes a plurality of protrusions extending from the inner end of the constriction ring.

The penile erection device is characterized in that the lugs extend from the tapered portion of the contraction ring at an open position between the tapered portions to form an expansion joint between the lugs at the tapered portion.

The penile erection device is characterized in that: the diaphragm is sealed with a handle integrally molded to the outer end of the diaphragm.

The penis erection device is characterized in that it also includes a device for removing air from the vacuum tube.

The penile erection device is characterized in that the penile erection device achieves a vacuum pressure of at least about 17 inches of mercury.

The utility model has the following advantages:

One of the advantages of this creation is its ability to swell the shaft, base and root of the male genitalia. The constriction ring is designed to fit the base of the penis reliably, and when vacuum pressure is applied to the vacuum tube, a part of the root of the penis is sucked into the constriction ring. Expansion of the base and base of the penis causes the penis to rise to a more natural erect position. The constriction ring also keeps the penis in an erect position after the vacuum tube is removed.

An added advantage of this creation is that the individual's hands remain free because the base of the penis does not become weak after removal of the vacuum tube, forming a "joint" around which the body of the penis may bend.

Yet another advantage of the present invention is that the constriction ring is designed to be easily positioned to the base of the male genitalia, with the tab of the ring abutting the individual's groin. The tabs of the constriction ring allow the individual to reliably maneuver the ring to an enlarged diameter or angled shape of the male genital base. The shrink ring is shaped to have an enlarged inner diameter along the length of the ring, moving from the outer edge of the tubular portion to the inner end of the tapered portion. The increased inner diameter keeps the ring fixed at the base of the penis both during expansion and during use.

Another advantage of the present invention is that the inner and outer ends of the constriction ring are rounded to help prevent the constriction ring from poking into the individual's skin, thereby providing a comfortable fit.

Yet another advantage of the present invention is that the diaphragm is designed to form a practical airtight seal against the shrink ring. The tubular portion of the shrink ring has a predetermined diameter that increases slightly from the outer end to the inner end of the shrink ring. The inner end of the septum has a thick rounded end with a predetermined diameter substantially equal to the diameter of the outer end of the tubular portion of the constriction ring. As air is removed from the vacuum tube, the tubular portion of the shrink ring slides into the diaphragm opening, forming a relatively airtight seal. This seal allows the vacuum pump to achieve a sufficient level of vacuum pressure to inflate the penis and draw a portion of the root of the penis into the constriction ring. This allows the penis to achieve a more natural erection both with the tube in use and after the tube has been removed.

Yet another advantage of the present invention is that no dirty lubricant is required to form the seal between the shrink ring and the diaphragm.

Yet another advantage of the invention is its reliability and ease of use. This creation provides a mount for placing the ring on the base of the penis. The tabs allow an individual to slide the ring from the narrow receiving end, along the length of the carrier, to its wider open end. After the penis is inserted into the open end of the cartridge, the individual can grasp the tabs and pull the loop off the cartridge and onto the base of the penis. The tabs also allow the individual to advance the ring further along the base of the penis, allowing a portion of the root of the penis to expand during use. Individuals can easily position the constriction ring at the base of the penis, helping to ensure a more natural erection with each use.

Yet another advantage of the present invention is that many different sizes of diaphragm seals and shrink rings can be provided in one complete kit including all penile erection device components. Individuals can choose the diaphragm and shrink ring that best fit them for the privacy of their own home, with a comfortable fit that produces good results according to individual needs. The inconvenience and embarrassment of visiting a doctor or shop is unnecessary.

Yet another advantage of this creation is its inexpensive component cost, and its relative ease of manufacture. For example, less expensive conventional plastic tubes can be used to control the vacuum tubes of this case. Flexible diaphragms and shrink rings can be effectively incorporated into conventional vacuum tube and pump designs, thereby avoiding expensive and time-consuming manufacturing costs.

From the following detailed description, in conjunction with the following drawings, will understand many other characteristics and advantages of this creation.

Detailed description:

Although this creation allows many different forms of embodiments, it is shown in the accompanying drawings, and a preferred embodiment of this creation will be described in detail in this text, and please understand that this case disclosure is regarded as an example of this creation principles and are not meant to limit the broad aspects of the invention to the illustrated embodiments.

As shown in Fig. 1, this creation is about a vacuum type penile erection device provided with a male genitalia 5 with an integral stem 6, a base 7 and a part 8. Erectile device 10 includes a vacuum tube 20 for insertion of the penis 5, a hand pump 40 for evacuating or removing air from the tube, a flexible diaphragm 50 to form a seal around the penis, and a vacuum tube for use after removal of the vacuum tube. Constriction ring 70 that holds the penis in the erect position.

Vacuum tube 20 is a conventional, generally cylindrical tube having a main closed end 22, an open end 24 about two inches in diameter and an inner surface 25 for receiving a male genitalia. Tube 20 is preferably made of a rigid clear plastic about 0.1 inches thick. Tube 20 is designed to retain its shape when a vacuum pressure of at least about 24 inches of mercury is achieved within the tube. An outwardly projecting lip 26 is formed around the periphery of the open end 24 . The lip 26 is approximately 0.25 inches in height and its edges are rounded for comfort. The main closed end 22 of the tube 20 has a teat opening 26 through which air is removed from the tube 20 . Tube 20 is sized and shaped to suit the male genitalia of a variety of individuals.

A pump 40 is used to evacuate or remove air from the vacuum tube 20 through the teat opening 28 . A flexible hose 42 connects the teat opening 28 to the pump 40 . The pump 40 should be capable of achieving a vacuum pressure of 24 inches above mercury. The pump 40 should also have a relief valve or vacuum limiter (not shown) set to open at 24 inches of mercury to prevent harmful vacuum pressure from being transmitted to the individual during use. In this way, the pump 40 can experience a reduction in attainable vacuum pressure due to wear over time without affecting the performance of the device 10 . While FIG. 1 shows a conventional manually operated pump 40 for removing or evacuating air from the tube 20, it will be appreciated that other evacuation means, such as electric pumps, may be used without departing from the present invention.

As shown in Figure 2, the diaphragm seal 50 is made of a single piece of soft, durable and flexible rubber to allow for comfortable bending and stretching during use. While diaphragm seal 50 is preferably made of synthetic or natural rubber, it should be understood that other materials with similar properties could be used. Da Goang Assorted Co.Ltd, Taipei City, Republic of China, has a product similar to the diaphragm seal 50 used in this invention.

As shown in FIG. 2, diaphragm seal 50 has a generally tubular shape when in its relaxed position. Diaphragm seal 50 has an inner end 52 , an intermediate portion 54 , and an outer end 56 . Inner end 52, intermediate portion 54 and outer end 56 are integrally formed and have a substantially uniform thickness in the relaxed state. The inner and outer ends 52 and 56 of the diaphragm seal 50 are respectively formed with inner and outer openings having predetermined diameters. The diameter of the opening within the inner end 52 seals against the shrink ring 70 as discussed below. The diameter of the outer opening is sized such that the stretchable outer end 56 fits and seals against the lip 26 of the vacuum tube 20 . The inner and outer ends 52 and 56 each have an integral tail end having a substantially circular cross-sectional area at 64 and 66 respectively. The walls of the tail ends 64 and 66 are thicker than the walls of the inner and outer ends 52 and 56 and are more resistant to stretching.

As shown in FIGS. 4-7 , the outer end 56 of the diaphragm seal 50 is folded over the lip 26 of the open end 24 of the vacuum tube 20 . Handles 58 are integrally formed with and extend outwardly from opposite sides of the outer end 56 of the diaphragm seal 50 . The thicker and more stretch resistant outer tail 66 helps maintain an airtight seal between the outer end 56 of the diaphragm seal 50 and the lip 26 of the vacuum tube 20 . The handle 58 allows the person using the device to easily release the septum seal 50 from the vacuum tube 20 after the male genitalia has inflated to the erect position as will be discussed later.

The shrink ring 70 is a whole piece of soft, durable and flexible rubber, so that it can be easily and comfortably bent and stretched during use. While the shrink ring is preferably made of synthetic or natural rubber, it is understood that other materials with similar characteristics may be used.

As best shown in FIGS. 3 and 10-12, the shrink ring 70 has a tubular portion 72 located near its outer end 73, a tapered portion 74 located near its inner end 75, and a plurality of tapered portions extending from the inner end of the tapered portion toward the inner end 75. The protruding tab 76. Tubular portion 72 has a length of about 0.50 inches and a thickness of about 0.045 inches. Tapered portion 74 has a length of approximately 0.25 inches and a varying thickness due to its circular inner surface 80 . Tapered portion 74 is generally larger than tubular portion 72 . Tubular portion 72 defines an opening at outer end 73 with a predetermined diameter of approximately one inch for receiving male genitalia 5 .

The inner and outer ends 75 and 73 of the shrink ring 70 are rounded for comfort and ease of use. The inner surface 80 of the inner end 75 is rounded to a radius of about 0.25 inches to provide a snug fit and to accommodate the generally thicker diameter of the base 7 of the male genitalia 5 . Although the inner surface 80 of the inner end 75 is illustrated as being circular, it will be appreciated that the inner surface may have a different arc. The outer surface 82 of the tapered portion 74 is chamfered at an angle of approximately 45 degrees. The outer end 73 of the shrink ring 70 is rounded to a radius of about 0.01 inches on both its inner and outer surfaces 80 and 82 . The inner surface 80 of the outer end 73 is rounded to provide a comfortable fit. The outer surface 82 of the outer end 73 is rounded to facilitate sliding abutment of the inner trailing end 64 of the diaphragm seal 50 in use, as discussed later. The inner surface 80 of the tubular portion 72 increases slightly in inner diameter and continues away from the outer end 73 towards the inner end 75 . The increase in inner diameter is more pronounced at tapered portion 74 due to the rounding of inner surface 80 of inner end 75 as discussed above. The continuously increasing diameter of the inner surface 80 enables the individual to fit the shrink ring to the base 7 of the penis 5 and helps keep the ring in this position during use. The continuously increasing diameter of the inner surface 80 also helps to form a gas-tight seal between the diaphragm 50 and the shrink ring 70 . Although the shrink ring 70 is shown as having a tapered portion 74 with a chamfered outer surface 82 meeting the tubular portion 72 at a 45 degree angle, it will be appreciated that the tapered and tubular portion outer surface 82 may form a continuous arc or round. As shown in Figure 13.

As best shown in FIGS. 10-12 , the tabs 76 of the shrink ring 70 are equally spaced apart from each other by a predetermined distance and have a predetermined width around the tapered portion 74 . Tabs 76 prevent tapered portion 74 of shrink ring 70 from stretching during use. The area between the tabs 76 forms an "expansion joint" at the tapered portion 74 which stretches more easily when vacuum is applied to the vacuum tube 20 and the base 7 of the male genitalia 5 expands. The tabs 76 are ribbed on their outer surface 82 to provide a more grippable surface.

The present invention provides a tubular carrier 100 with an open end 102 to facilitate placement of the shrink ring around the male genitalia 5 . The shrink ring 70 is inserted around the narrow end 104 of the cartridge 100 . The individual can then grasp the tab 76 of the shrink ring 70 and slide the shrink ring along the length of the cartridge to the open end 102 . The larger diameter of the open end 102 stretches the diameter of the tapered and tubular portions 74 and 72 of the constriction ring 70 to facilitate placement at the base 7 of a flaccid penis. The cartridge 100 may have grooves 106 formed therein to help reduce the force required to slide the shrink ring along the length of the cartridge. Operation of the device

While the operation of the invention should be understood from the above description, the following description is provided to more easily explain the operation of device 10 . The device 10 may be provided in the form of a complete kit that an individual may purchase and take to the privacy of his or her home. The kit includes - a vacuum tube 20, a manual or automatic pump 40 with a corresponding flexible hose 42, a number of diaphragm seals 50 each having an inner opening of a different diameter, and a number of shrink rings 70 each having a different inner diameter to cooperate with one of the diaphragms Outer end 73 . Individuals can then select a cooperative diaphragm seal 50 and constriction ring 70 that comfortably and effectively fit their male genitals.

As shown in FIG. 3 , an appropriate shrink ring 70 is inserted into the cartridge 100 and slid down to its open end 102 . A dry powder, such as baby powder, can be used to help reduce the force required to slide the shrink ring along the loader 100 . The flaccid penis is then inserted into the open end 102 of the holder 100 and the shrink ring 70 is slid off the holder and onto the penis 5 as close to its base 7 as possible. The individual can use the tabs 76 to manipulate the constriction ring 70 as far down the base 7 of the penis 5 as possible.

The tip of the penis 5 is then aligned and positioned against the opening on the inner end 52 of the septum seal 50 as shown in FIG. 4 . A diaphragm seal has been secured to the open end 24 of the vacuum tube 20 . The pump 40 is then activated and the pumping of air from the tube 20 begins. This causes the male genitalia 5 to be sucked into the tube 20 as shown in FIG. 5 . Initially, the diaphragm seal 50 rests against the shaft 6 of the penis 5 . This seal enables the pump to achieve an intermediate amount of vacuum pressure within vacuum line 20. The penis starts to expand through the intermediate amount of vacuum pressure and starts to suck the base 8 of the penis 5 towards the constriction ring 70 . The vacuum pressure also causes the shrink ring to move toward the inner end 52 of the diaphragm 50 . The deeper the shrink ring 70 is secured into the diaphragm seal 50, the better the seal will be due to its conical shape and greater shrink force.

When the vacuum chamber 20 reaches a first predetermined amount of vacuum pressure, the inner surface 60 of the inner tail end 64 of the diaphragm 50 abuts the outer end 73 of the shrink ring 70 and slides up to and seals against the shrink ring as shown in FIG. 6 The outer surface 82 of the tubular portion 72 . This creates a virtually airtight seal and enables pump 40 to generate a greater amount of vacuum pressure within vacuum tube 20 . The greater vacuum pressure may be in the range of about 17 to 24 inches of mercury below atmospheric pressure. The greater vacuum pressure causes the penis to reach a more inflated state and draws the base 8 of the penis 5 into the constriction ring 70 . It is believed that greater vacuum pressure also causes some portions of the base 8 of the penis 5 to expand. Expansion of the base 7 and root 8 of the penis 5 causes the shaft 6 of the penis to lift to produce a more natural and functional erection as shown in FIG. 7 .

After the diaphragm 50 seals against the shrink ring 70 and the vacuum tube 20 reaches a second predetermined amount of vacuum pressure, the inner end 52 of the diaphragm 50 can be inverted so that the diaphragm forms an "S" shape as shown in FIG. After inverting into the "S" shape, the outer surface 62 of the inner tail end 64 of the diaphragm 50 contacts and seals against the outer surface 82 of the shrink ring 70 . The amount of vacuum pressure required to achieve the first and second predetermined pressures will vary from person to person depending on various factors such as the size, shape and characteristics of the male genitalia 5, diaphragm 50 and constriction ring 70.

The pump 40 is then turned off and the flexible hose 42 is detached from the teat opening 28 of the vacuum tube 20, allowing the vacuum pressure to be released from the tube 20. The individual then uses the handle 58 to detach the septum seal 50 from the vacuum tube 20 as shown in FIG. 8 . The diaphragm 50 is crimped against and held in the shrink ring 70 . The penis 5 remains in its natural erect position after removal of the vacuum tube 20 because it is believed that some portion of the base 8 has been sucked into the constriction ring 70 causing blood to remain in the expanded base.

Please understand that this creation can be embodied in other specific forms without departing from the spirit or central characteristics of this creation. The examples and embodiments of the creation are to be considered in all respects illustrative rather than restrictive, and the creation is not limited to the details set forth herein.
