Description

Technical Field

[0001] The invention relates to an erection aid for assisting male penis erection. Background Art

[0002] Statistics show that about 5%-10% of men aged 18-40 have experienced erectile dysfunction to varying degrees, about 10%-20% of men aged 40-49 have erectile dysfunction to varying degrees, about 20%-40% of men aged 50-59 have erectile dysfunction, and more than 50% of men over 60 have erectile dysfunction.

[0003] The structure of the penis Figures 1 to 3 As shown, it includes a penis body and a scrotum 0-2, the upper side of the penis body is connected to the mons pubis 0-1 at the penis root line 1, the root of the penis body is provided with a urethral bulb 0-4, the lower side of the penis body has a urethral corpus cavernosum 4 and a left corpus cavernosum 3-1 and a right corpus cavernosum 3-2 located on the left and right sides of the urethral corpus cavernosum. The corpus cavernosum has a corpus cavernosum artery that supplies blood to the corpus cavernosum, and the corpus cavernosum has a corpus cavernosum artery that supplies blood to the corpus cavernosum. The upper side of the penis body is also distributed with a superficial dorsal penis vein, a deep dorsal penis vein, and a penis renal artery, etc. The blood vessels on the upper side of the penis body are also called dorsal penis blood vessels, which are mainly used to maintain the nutrition supply of the penis body. Item 0-3 in the figure represents the foot of the penis.

[0004] For the problem of erectile dysfunction, it is necessary to use appropriate drugs to assist erection or physical devices to assist erection. From the mechanism of penile erection, penile erection is a process of congestion and expansion of the corpus cavernosum of the penis and the corpus cavernosum of the urethra. Therefore, the principle of physical assistance to erection is nothing more than to achieve congestion of the corpus cavernosum of the penis and the corpus cavernosum of the urethra through physical means.

[0005] The existing physical erection aid includes a penis sleeve for being sleeved on the penis body. When in use, the penis sleeve is evacuated to maintain a negative pressure environment in the penis sleeve, thereby ensuring the blood supply state of the penis corpus cavernosum and the urethral corpus cavernosum to assist the penis erection. However, the problem with this erection aid is that although the long-term negative pressure state can achieve congestion of the corresponding corpus cavernosum, the negative pressure makes the blood in the penis position basically in a stagnant state. Long-term blood stagnation will cause certain damage to the penis, which is manifested in the penis appearing black and purple; in addition, the blood supply pressures required for the penis corpus cavernosum and the urethral corpus cavernosum are different. The erection pressure of the urethral corpus cavernosum is basically half of the erection pressure of the penis corpus cavernosum. If the erection pressure of the penis corpus cavernosum is low, it will cause the penis to lose erection hardness; if the erection pressure of the urethral corpus cavernosum is high, it will cause the urethral corpus cavernosum to swell too much, resulting in abnormal visual expression of the urethral corpus cavernosum. The existing technology cannot distinguish the blood supply pressure, so it is impossible to truly achieve penis assisted erection. Summary of the Invention

[0006] The object of the present invention is to provide an erection assisting device capable of distinguishing the erection pressures of the corpus spongiosum urethrae and the corpus cavernosum penis.

[0007] To solve the above technical problems, the technical solution of an erection assisting device in the present invention is as follows: An erection assisting device includes a C-shaped base body for being placed under the penis body during use. The length direction of the C-shaped base body is the same as the reverse of the length of the penis body. Inside the C-shaped base body, there are three groups of left pressing groups, middle pressing groups, and right pressing groups arranged in sequence along the circumferential direction of the C-shaped base body. The left pressing group is used to press the left corpus cavernosum penis, the middle pressing group is used to press the corpus spongiosum urethrae, and the right pressing group is used to press the right corpus cavernosum penis. Each pressing group includes a first corpus cavernosum pressing head, a second corpus cavernosum pressing head, and a third corpus cavernosum pressing head that can act independently and are arranged in sequence along the blood flow direction of the arterial blood vessels in the corresponding corpus cavernosum. Each corpus cavernosum pressing head presses the target blood vessel by expanding with a medium filled inside, or the corpus cavernosum pressing head presses the target blood vessel by moving up and down.

[0008] Furthermore, a limiting ring for sleeving on the root of the penis is provided at the front end of the C-shaped base body. A limiting ring pressing head for pressing the blood vessels on the upper side of the penis body is provided on the inner side of the upper end of the limiting ring. The limiting ring pressing head presses the target blood vessel by expanding with a medium filled inside, or the limiting ring pressing head presses the target blood vessel by moving up and down.

[0009] Furthermore, an upper suction cup is connected to the limiting ring, and a lower suction cup is connected to the end of the C-shaped base body far from the limiting ring.

[0010] Furthermore, for each pressing group, the length of the second corpus cavernosum pressing head is greater than the length of the first corpus cavernosum pressing head, and the length of the second corpus cavernosum pressing head is greater than the length of the third corpus cavernosum pressing head.

[0011] Furthermore, each corpus cavernosum pressing head is a sac-like structure made of an elastic material, and each corpus cavernosum pressing head presses the target blood vessel by expanding with a medium filled inside.

[0012] Furthermore, a medium inlet and outlet is provided on each corpus cavernosum pressing head, and a switching valve is connected to the medium inlet and outlet.

[0013] Furthermore, the height of the second corpus cavernosum pressing head in the left pressing group and the right pressing group is higher than the height of the second corpus cavernosum pressing head in the middle pressing group.

[0014] Furthermore, the pressing force of the second corpus cavernosum pressing head in the left pressing group and the right pressing group is greater than the pressing force of the second corpus cavernosum pressing head in the middle pressing group.

[0015] The beneficial effects of the present invention are as follows: The first sponge press head and the third sponge press head serve as valve structures for blood vessels, and their main function is to close the target blood vessels. The second sponge press head serves as a pumping pressure for blood vessels. When in use, the limiting ring is sleeved on the root of the penis. The function of the third sponge press head is to close the downstream position of the pressed section of the target blood vessel by pressing the target blood vessel. The function of the first sponge press head is to close the upstream position of the pressed section of the target blood vessel by pressing the target blood vessel. Each sponge press head in the left pressing group presses the arterial blood vessels in the left corpus cavernosum penis, each sponge press head in the right pressing group presses the arterial blood vessels in the right corpus cavernosum penis, and each sponge press head in the middle pressing group presses the corpus spongiosum urethrae. During specific operation, when the corresponding third sponge press head does not press the target blood vessel, the first sponge press head presses the target blood vessel, and the second sponge press head works to press the target blood vessel between the first sponge press head and the second sponge press head, so that the blood in this section of blood vessel obtains a certain pressure, and the blood will flow to the corresponding corpus cavernosum under the action of the pressure, thereby realizing the erectile assistance effect of corpus cavernosum congestion. Each pressing group is independently controlled, so the erectile pressure of the corpus spongiosum urethrae and the corpus cavernosum penis can be controlled. Description of the Drawings

Detailed implementation manners

[0017] For the convenience of understanding the present invention, the present invention will be described in more detail below with reference to the accompanying drawings and specific embodiments. The preferred embodiments of the present invention are given in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure content of the present invention more thorough and comprehensive.

[0018] It should be noted that unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not used to limit the present invention.

[0019] An embodiment of an erection assist device in the present invention is as follows Figures 1 to 12 as shown: Before introducing the structure of this erection assist device, a brief introduction to the structure of the penis is made first, as Figures 1 to 3 shown: The penis includes the penis body and the scrotum 0-2. The connection position between the upper side of the penis body and the mons pubis 0-1 is the penile root line 1. The root of the penis body is provided with the bulb of the urethra 0-4. The lower side of the penis body has the corpus spongiosum urethrae 4 and the left corpus cavernosum penis 3-1 and the right corpus cavernosum penis 3-2 on the left and right sides of the corpus spongiosum urethrae. There is the corpus cavernosum artery that supplies blood to the corpus cavernosum penis in the corpus cavernosum penis, and there is the corpus spongiosum artery that supplies blood to the corpus spongiosum urethrae in the corpus spongiosum urethrae. The upper side of the penis body is also distributed with the superficial dorsal vein of the penis, the deep dorsal vein of the penis, and the renal artery of the penis, etc. The blood vessels on the upper side of the penis body are also called the dorsal blood vessels of the penis 5, which are mainly used to maintain the nutritional supply of the penis body. Item 0-3 in the figure represents the crus of the penis.

[0020] The structure of the erection assist device in the present invention is as Figures 4 to 12 shown: It includes a C-shaped base body 6 for being placed under the penis body during use. The length direction of the C-shaped base body 6 is consistent with the length direction of the penis body. The front end of the C-shaped base body 6 is provided with a limiting ring 7 for sleeving and connecting to the root of the penis. An upper suction cup 8 is connected to the limiting ring. The left and right sides at the rear end of the C-shaped base body are connected with lower suction cups 10. The upper suction cup 8 is used for adsorbing and connecting to the lower side part of the patient's lower abdomen, and the lower suction cups 10 are used for adsorbing and connecting to the left and right sides of the patient's perineum. The upper suction cup is provided with an upper suction cup suction port 9, and the lower suction cup is provided with a lower suction cup suction port 11.

[0021] Inside the C-shaped base body, there are three groups of left pressing groups 12, middle pressing groups 13, and right pressing groups 14 arranged in sequence along the circumferential direction of the C-shaped base body. The left pressing group 12 is used for pressing the left corpus cavernosum penis 3-1, the middle pressing group 13 is used for pressing the corpus spongiosum urethrae 4, and the right pressing group 14 is used for pressing the right corpus cavernosum penis 3-2. Each pressing group includes a first corpus cavernosum pressing head 15, a second corpus cavernosum pressing head 16, and a third corpus cavernosum pressing head 17 that can independently act and are arranged in sequence along the blood flow direction of the artery blood vessels in the corresponding corpus cavernosum. Each corpus cavernosum pressing head presses the target blood vessel by expanding with the medium filled inside, or the corpus cavernosum pressing head presses the target blood vessel by moving up and down. Specifically, each corpus cavernosum pressing head of the left sponge group is used for pressing the corpus cavernosum artery in the left corpus cavernosum penis; each corpus cavernosum pressing head of the right sponge group is used for pressing the corpus cavernosum artery in the right corpus cavernosum penis, and each corpus cavernosum pressing head of the middle sponge group is used for pressing the corpus spongiosum artery in the corpus spongiosum urethrae.

[0022] On the inner side of the upper end of the limiting ring, there is a limiting ring pressing head 18 for pressing the blood vessels on the upper side of the penile body. The limiting ring pressing head 18 presses the target blood vessels by expanding with a medium filled inside, or the limiting ring pressing head presses the target blood vessels by moving up and down.

[0023] In this embodiment, for each pressing group, the length of the second corpus cavernosum pressing head is greater than the length of the first corpus cavernosum pressing head, and the length of the second corpus cavernosum pressing head is greater than the length of the third corpus cavernosum pressing head.

[0024] In this embodiment, for each pressing group, the length of the second corpus cavernosum pressing head is greater than the length of the first corpus cavernosum pressing head, and the length of the second corpus cavernosum pressing head is greater than the length of the third corpus cavernosum pressing head.

[0025] The limiting ring pressing head 18 and each corpus cavernosum pressing head are both sac-like structures made of elastic materials. The limiting ring pressing head and each corpus cavernosum pressing head press the target blood vessels by expanding with a medium filled inside. The medium in this embodiment is preferably gas. In other embodiments of the present invention, this medium can also be a liquid medium.

[0026] Each corpus cavernosum pressing head is provided with a medium inlet and outlet, and a switching valve is connected to the medium inlet and outlet. The medium inlet and outlet connected to the limiting ring pressing head is called the medium inlet and outlet 38 of the limiting ring pressing head. The medium inlets and outlets corresponding to the corpus cavernosum pressing heads of the left pressing group are respectively called the medium inlet and outlet 29 of the first corpus cavernosum pressing head of the left pressing group, the medium inlet and outlet 33 of the second corpus cavernosum pressing head of the left pressing group, and the medium inlet and outlet 31 of the third corpus cavernosum pressing head of the left pressing group; the medium inlets and outlets corresponding to the corpus cavernosum pressing heads of the right pressing group are respectively called the medium inlet and outlet 30 of the first corpus cavernosum pressing head of the right pressing group, the medium inlet and outlet 34 of the second corpus cavernosum pressing head of the right pressing group, and the medium inlet and outlet 32 of the third corpus cavernosum pressing head of the right pressing group; the medium inlets and outlets corresponding to the corpus cavernosum pressing heads of the middle pressing group are respectively called the medium inlet and outlet 35 of the first corpus cavernosum pressing head of the middle pressing group, the medium inlet and outlet 36 of the second corpus cavernosum pressing head of the middle pressing group, and the medium inlet and outlet 37 of the third corpus cavernosum pressing head of the middle pressing group.

[0027] In this embodiment, the left corpus cavernosum and the right corpus cavernosum of the penis need to obtain a greater erection pressure than the corpus spongiosum urethrae. Therefore, the pressing force of the second corpus cavernosum pressing head in the left pressing group and the right pressing group is greater than the pressing force of the second corpus cavernosum pressing head in the middle pressing group. In other embodiments of the present invention, the difference in this erection pressure can also be controlled by the height of the second corpus cavernosum pressing head in different pressing groups. For example, the height of the second corpus cavernosum pressing head in the left pressing group and the right pressing group is higher than the height of the second corpus cavernosum pressing head in the middle pressing group.

[0028] The erection aid further includes a gas supply device, which includes an air pump 19. A gas supply pipeline 21 is connected to the air outlet of the air pump, and a gas return pipeline 22 is connected to the air return port of the air pump.

[0029] The gas supply device further includes a two-position two-way valve 20, a first two-position three-way valve 23, a second two-position three-way valve 24, a third two-position three-way valve 25, a pressure regulating solenoid valve group 26, a fourth two-position three-way valve 27, and a fifth two-position three-way valve 28.

[0030] One gas port of the two-position two-way valve 20 is connected to the gas return pipeline, and the other gas port of the two-position two-way valve is communicated with the external atmospheric pressure, so as to ensure that the gas return pipeline can be quickly depressurized.

[0031] Two gas ports of the first two-position three-way valve 23 are respectively connected to the gas supply pipeline and the gas return pipeline, and the other gas port of the first two-position three-way valve is connected to the medium inlets and outlets 29 and 30 of the first sponge pressing head of the left pressing group and the medium inlets and outlets 30 of the first sponge pressing head of the right pressing group.

[0032] Two gas ports of the second two-position three-way valve 24 are respectively connected to the gas supply pipeline and the gas return pipeline, and the other gas port of the second two-position three-way valve is connected to the medium inlets and outlets 31 of the third sponge pressing head of the left pressing group and the medium inlets and outlets 32 of the third sponge pressing head of the right pressing group.

[0033] Two gas ports of the third two-position three-way valve 25 are respectively connected to the gas supply pipeline and the gas return pipeline, and the other gas port of the third two-position three-way valve is connected to the medium inlets and outlets 33 of the second sponge pressing head of the left pressing group and the medium inlets and outlets 34 of the second sponge pressing head of the right pressing group.

[0034] The pressure regulating solenoid valve group 26 is composed of seven two-position two-way valves. The connection relationship of these seven two-position two-way valves is as Figure 12 shown. Four of the two-position two-way valves are respectively connected to the medium inlets and outlets 35 of the first sponge pressing head of the middle pressing group, the medium inlets and outlets 36 of the second sponge pressing head of the middle pressing group, the medium inlets and outlets 37 of the third sponge pressing head of the middle pressing group, and the medium inlets and outlets 38 of the limiting ring pressing head. The output air pressure can be reduced through the pressure regulating solenoid valve group, so that the erection pressure of the urethral sponge body is lower than the erection pressure of the corpus cavernosum of the penis.

[0035] One gas port of the fourth two-position three-way valve 27 and the fifth two-position three-way valve 28 is communicated with the atmosphere, the other gas port is communicated with the gas return pipeline, and the remaining gas port is respectively connected to the upper suction port 9 and the lower suction port 11.

[0036] When in use, the fiber loop can be connected to the root of the penis. The scrotum is moved to the left and right sides of the C-shaped base, with the lower suction cup corresponding to the perineum and the upper suction cup corresponding to the lower abdomen. Through the negative pressure of the upper and lower suction cups, the C-shaped base can be firmly fixed to the lower side of the patient's penis. In other embodiments of the present invention, the bottom of the C-shaped base can also be entirely located above the scrotum.

[0037] The first cavernous body pressing heads of each pressing group act synchronously, the second cavernous body pressing heads of each pressing group act synchronously, and the third cavernous body pressing heads of each pressing group act synchronously. The limiting ring pressing head can act periodically to avoid long-term blockage of the blood vessels on the back of the penis and ensure the blood supply to the penis.

[0038] The first cavernous body pressing head and the third cavernous body pressing head are mainly used to press and seal the ends of the corresponding target blood vessel segments through pressing. The second cavernous body pressing head is mainly used to pump blood by pressing the target blood vessel segment between the first cavernous body pressing head and the third cavernous body pressing head.

[0039] As Figure 11 shown, the working principle of the erectile assist device of the present invention is introduced by taking the use process of the middle pressing group as an example. Figure 11 Item 39 in the figure represents the cavernous artery in the corpus spongiosum urethrae. The single arrow indicates the flow direction of blood in the cavernous artery of the corpus spongiosum urethrae. When in use, the first cavernous body pressing head inflates to press the lower end of the target blood vessel segment, and the lower end of the target blood vessel segment is sealed. Subsequently, the second cavernous body pressing head inflates to press the target blood vessel segment. Since the lower end of the target blood vessel segment is sealed by the first cavernous body pressing head, under the pressing action of the second cavernous body pressing head, the blood in the target blood vessel segment can be pumped upward directionally, promoting blood pumping into the corpus spongiosum urethrae. Subsequently, the third cavernous body pressing head inflates to press and block the upper end of the target blood vessel segment. Then, the first cavernous body pressing head and the second cavernous body pressing head deflate, and the target blood vessel segment is filled with blood. Then, the first cavernous body pressing head inflates and the third cavernous body pressing head deflates, and so on in a cycle to achieve assisted blood pumping towards the corresponding corpus cavernosum.
