Description

Technical Field

[0001] The present invention relates to the technical field of artificial insemination devices, and in particular to a home-use insemination and pregnancy-assisting device and method. Background Art

[0002] At present, it is common in clinical practice that sexual dysfunction due to physical illness or mental and psychological factors leads to the inability of the couple to have normal sexual intercourse, or the man cannot complete ejaculation in the vagina during sexual intercourse, resulting in inability to get pregnant normally. Now, for these couples, the Reproductive Medicine Center can inject the treated sperm suspension into the female uterine cavity through a medical intrauterine artificial insemination tube in the hospital for treatment after evaluating the patency of the fallopian tube and the male's semen analysis. However, the treatment process requires the patient to actively seek medical treatment and cooperate, which requires a certain amount of medical expenses, and women need to undergo invasive examinations and treatments before treatment, such as gynecological examinations and salpingography for women whose hymen has not been ruptured. Due to factors such as fear and tension, women often find it difficult to cooperate during the examination and treatment process and may need to undergo mental and psychological stimulation. At the same time, since sexual dysfunction involves very private issues, there are still many couples who are conservative or ashamed to go to the hospital for treatment in the future, but because the semen cannot be ejaculated into the vagina, they cannot get pregnant normally for many years, and they suffer great pressure and pain, and even family breakdown. In fact, if the semen cannot enter the vagina simply because of sexual intercourse or ejaculation disorders, couples can try vaginal insemination at home in order to get pregnant. The operation is relatively simple, can effectively solve this problem, and is private.

[0003] However, currently, there is no dedicated device that can be used for self-insemination at home. The female vagina is relatively sensitive, and women with sexual dysfunction often experience contraction and closure of the vaginal opening or vaginal wall due to tension and fear. If an ordinary syringe is used, it is difficult to insert directly due to its diameter and shape, and it is easy to damage the vagina, reducing the comfort of insemination; the length of the existing syringe does not match the length of the vagina, and the semen cannot be properly delivered to the vaginal vault, and it requires manual ejaculation of semen, which is inconvenient for one person to operate, reducing the convenience and success rate of insemination, and also greatly reducing the success rate of conception. Therefore, a home self-service insemination assisted pregnancy device and method is proposed. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that there is currently no special device that can be used for self-insemination at home. In order to invent a home self-help device that is easy to operate, matches the vaginal structure, avoids damage to the vaginal wall, is highly comfortable, and can help patients adapt to normal sexual intercourse, overcome fear and lose confidence, thereby achieving the treatment of sexual dysfunction and infertility.

[0033] Embodiment 1:

[0034] Reference Figure 1-Figure 8 , an insemination and pregnancy-assisting device, including an insemination tube 1, and the insemination tube 1 is made of a transparent and relatively soft material, the top of the insemination tube 1 is fixedly connected to a mounting seat 2, and an injection hole 21 is opened at the bottom of the insemination tube 1, and also includes: a cap 3 threadedly connected to the mounting seat 2, the cap 3 is provided with a piston part for extracting semen, and the cap 3 is provided with a power storage part for promoting rapid injection of semen; an elastic bag 4 attached to the surface of the insemination tube 1, the mounting seat 2 is provided with an inflation part for driving the elastic bag 4 to reciprocately expand, and the mounting seat 2 is provided with an unlocking part for releasing semen.

[0035] Reference Figure 1 , Figure 2 and Figure 4 , which also includes a sperm collection cup 9, the end of the sperm collection cup 9 is threadedly connected to a storage cover 91, and a storage groove 92 is opened in the middle of the storage cover 91, and the storage groove 92 is inserted into the outer wall of the insemination tube 1; the piston part includes a piston rod 5, the piston rod 5 passes through the cap 3 and is slidably connected thereto, the bottom end of the piston rod 5 is fixedly connected to a piston push block 51, the piston push block 51 fits and slides with the inner wall of the insemination tube 1, and the top of the piston rod 5 is fixedly connected to a push-pull piece 52; an arc slide 22 is arranged between the injection hole 21 and the inner cavity of the insemination tube 1, the arc slide 22 is arranged in an inverted "eight" shape, and the inner diameter of the inlet end of the arc slide 22 is larger than the inner diameter of the output end, the inner diameter of the inlet end of the arc slide 22 is the same as the inner diameter of the insemination tube 1, and the inner diameter of the outlet end of the arc slide 22 is the same as the inner diameter of the injection hole 21, and the bottom of the piston push block 51 is adapted to the inner cavity of the arc slide 22.

[0036] Through the arrangement of the above structure, semen is collected into the semen collection cup 9, and then the cap 3 is threadedly fixed on the mounting seat 2, and the push-pull piece 52 is pressed to push the piston rod 5 and the piston push block 51 to move toward the bottom of the inner cavity of the insemination tube 1, and finally the piston push block 51 is inserted into the arc-shaped slideway 22; then the bottom end of the insemination tube 1 is inserted into the semen collection cup 9, so that the injection hole 21 enters the semen, and then the push-pull piece 52 is pulled upward to drive the piston rod 5 and the piston push block 51 to move upward, thereby generating negative pressure suction in the insemination tube 1, so that the semen in the semen collection cup 9 is sucked into the insemination tube 1, In this way, the extraction of semen is completed; and due to the setting of the arc-shaped slide 22, the aperture of the semen discharge becomes smaller, thereby accelerating the ejection speed and impact of the semen, so that the semen can smoothly reach the uterus and improve the success rate of conception; and after the insemination is completed, the various components are disassembled and cleaned, and finally the various components are assembled, and the semen collection cup 9 and the storage cover 91 are threadedly fixed and sleeved on the bottom outer wall of the insemination tube 1, so as to block the inside of the insemination tube 1 and prevent external dust and bacteria from entering the insemination tube 1, reducing the difficulty of cleaning when it is used again and improving the convenience of use.

[0037] Reference Figure 2 , Figure 4 and Figure 6 The force storage part includes a force storage spring 6, which is sleeved on the piston rod 5 between the cap 3 and the piston push block 51, and the two ends of the force storage spring 6 are respectively fixedly connected to the cap 3 and the piston push block 51, and a limiting part for fixing the piston rod 5 is provided on the mounting seat 2; the limiting part includes a positioning rod 61, which is fixed to the top of the mounting seat 2, and the positioning rod 61 is symmetrically arranged with two groups along the central axis of the piston rod 5, and a rotating ring 62 is rotatably connected to the positioning rod 61, and the outer surface of the rotating ring 62 is A locking rod 621 and a paddle 622 are fixedly connected to the wall respectively, and locking grooves 63 are provided on both sides of the piston rod 5. The end of the locking rod 621 is movably connected to the locking groove 63. A limiting guide groove 64 is provided in the cap 3, and a limiting slide bar 641 is slidably connected in the limiting guide groove 64. The top end of the limiting slide bar 641 is rotatably connected to the paddle 622, and a locking spring 642 is fixedly connected to the outer wall of the limiting slide bar 641 located between the limiting guide groove 64 and the paddle 622.

[0038] Through the arrangement of the above structure, when the piston rod 5 is pulled upward to extract semen, the force storage spring 6 will be compressed, and when the piston rod 5 moves upward, the locking groove 63 will move to the locking rod 621. At this time, the locking rod 621 will be engaged with the locking groove 63 under the rebound action of the locking spring 642 (the locking spring 642 is in a compressed state in the initial state), thereby locking the piston rod 5, so that the piston push block 51 is fixed after obtaining the rebound potential energy, so as to carry out subsequent operations, thereby improving the convenience of insemination.

[0039] When the piston rod 5 wants to move downward smoothly, the piston rod 5 should be turned downward to pass the locking groove 63. When the piston rod 5 wants to move downward smoothly, the limit slide bar 641 should be pulled up by the paddle 622. However, the bottom of the limit slide bar 641 has reached the top of the groove at the bottom end of the limit guide groove 64, so that the piston rod 5 can no longer rotate downward and can only rotate upward, thereby realizing the limit of the limit slide bar 641 and completing the locking of the piston rod 5.

[0040] Reference Figure 4 , Figure 8 The inflation portion includes an inflation groove 7, which is provided in the mounting seat 2, and the side wall of the inflation groove 7 is fixed and connected with an inflation tube 71, and the other end of the inflation tube 71 is fixed and connected with an elastic ball 72. Expansion grooves 73 are provided on the outer wall of the insemination tube 1 at equal intervals, and the elastic bag 4 is fixed in the expansion groove 73, and multiple groups of expansion grooves 73 on the same axis are connected through an air guide groove 731, and the end of the air guide groove 731 is connected with the inner cavity of the inflation groove 7.

[0041] By setting the above structure, the elastic ball 72 is pressed while the insemination tube 1 is inserted into the vagina, so that the gas inside the elastic ball 72 enters the inflation groove 7 along the inflation tube 71, and then enters each group of expansion grooves 73 along the air guide groove 731, so that the elastic bag 4 expands outward, and then the elastic ball 72 is released. Under its rebound effect, the gas will flow back, so that the elastic bag 4 will shrink and reset. This reciprocating process will make the elastic bag 4 continuously expand and shrink in the vagina, simulating the process of the penis repeatedly expanding the vagina during sexual intercourse, achieving a massage effect on the vagina, thereby relaxing the sphincter and pelvic floor muscles around the vagina, so that the insemination tube 1 can be smoothly inserted into the vagina, effectively reducing the damage to the vagina, improving the comfort of insemination, and helping women with sexual dysfunction to reduce their fear of sexual intercourse, helping them to adapt to and establish a normal sex life, and achieving the purpose of treatment. Moreover, when the internal muscles of the vagina are subjected to reciprocating expansion and contraction, it can induce a neuroendocrine response in the body, promote the secretion of vaginal secretions, peristalsis of the endometrium and fallopian tube mucosa, and uterine contraction, which is beneficial for sperm to enter the uterine cavity from the vagina and then move quickly to the fallopian tube, thereby increasing the success rate of conception.

[0042] Reference Figure 4-Figure 6, wherein the unlocking part includes a bearing ring 8, which is rotatably connected to the outer wall of the insemination tube 1 located in the inflation groove 7, and a pneumatic impeller 81 is fixedly connected to the outer wall of the bearing ring 8. The output end of the inflation tube 71 faces the outer wall of the pneumatic impeller 81, and an unlocking slide groove 82 is provided on the mounting seat 2. The unlocking slide groove 82 is communicated with the inner cavity of the inflation groove 7, and an unlocking ring 821 is slidably connected in the unlocking slide groove 82. The unlocking ring 821 penetrates into the inflation groove 7 and is fixedly connected to the outer wall of the bearing ring 8, and magnetic blocks 822 are fixedly connected to both sides of the top of the unlocking ring 821, and the magnetic blocks 822 and the bottom end of the limiting slide bar 641 are magnetically attracted; the inner diameter center of the unlocking slide groove 82 is aligned with the central axis of the limiting guide groove 64, and the magnetic attraction between the magnetic block 822 and the limiting slide bar 641 is greater than the pulling force required for the locking spring 642 to retract.

[0043] Through the arrangement of the above structure, the airflow entering the inflation groove 7 along the inflation tube 71 will also drive the pneumatic impeller 81 to rotate. When the massage reaches a certain number of times, the unlocking ring 821 will move to the bottom of the limiting slide bar 641 with the magnetic block 822. At this time, under the attraction between the magnetic block 822 and the limiting slide bar 641, the limiting slide bar 641 will move downward, thereby pulling the paddle 622 to rotate downward, and at this time the locking rod 621 will rotate upward and finally disengage from the locking groove 63. At this time, under the rebound action of the force storage spring 6, the piston push block 51 will be pushed to reset quickly, thereby pushing the semen into the vagina. At this time, the semen will produce a certain accelerated injection effect under the thrust of the elastic potential energy conversion, so that the semen can smoothly enter the uterus, effectively improving the success of conception.

[0044] It needs to be explained that due to the effect of friction, each pressing of the elastic ball 72 will only cause the pneumatic impeller 81 to rotate at a small angle. In this way, the pneumatic impeller 81 can be rotated to a corresponding angle only after sufficient massage. While ensuring the massage effect, it also realizes the self-ejection of semen, effectively improving the convenience of use.

[0045] In addition, it should be noted that the multiple elastic bags 4 distributed in an annular shape may also be an integral expansion bag. Thus, when the expansion bag expands and retracts back and forth, it can be like the penis erecting as a whole, thus better simulating the process of the penis repeatedly expanding the vagina during sexual intercourse, thereby effectively improving the pregnancy rate.

[0046] Reference Figure 1-Figure 8In the present invention, when in use, first collect the semen into the semen collection cup 9, then screw the cap 3 onto the mounting seat 2, and press the push-pull sheet 52 to push the piston rod 5 and the piston push block 51 to move toward the bottom of the inner cavity of the insemination tube 1, and finally make the piston push block 51 plug into the arc-shaped slideway 22; then insert the bottom end of the insemination tube 1 into the semen collection cup 9, so that the injection hole 21 enters the semen, and then pull the push-pull sheet 52 upward to drive the piston rod 5 and the piston push block 51 to move upward , while compressing the storage spring 6, negative pressure suction is generated in the insemination tube 1, so that the semen in the sperm collection cup 9 is sucked into the insemination tube 1, and in the process of the piston rod 5 moving upward, the locking groove 63 will move to the locking rod 621. At this time, the locking rod 621 will be locked into the locking groove 63 under the rebound action of the locking spring 642, thereby locking the piston rod 5, so that the piston push block 51 is fixed after obtaining the rebound potential energy, so as to carry out subsequent operations, thereby improving the convenience of insemination.

[0047] Then, the insemination tube 1 is inserted into the vagina, and the elastic ball 72 is pressed at the same time, so that the gas inside the elastic ball 72 enters the inflation groove 7 along the inflation tube 71, and then enters each group of expansion grooves 73 along the air guide groove 731, so that the elastic bag 4 expands outward, and then the elastic ball 72 is released. Under its rebound effect, the gas will flow back, so that the elastic bag 4 will shrink and reset. This reciprocating process will cause the elastic bag 4 to continuously expand and shrink in the vagina, simulating the process of the penis repeatedly expanding the vagina during sexual intercourse, achieving a massage effect on the vagina, thereby relaxing the sphincter and pelvic floor muscles around the vagina, so that the insemination tube 1 can be smoothly inserted into the vagina, effectively reducing the damage to the vagina, improving the comfort of insemination, and helping women with sexual dysfunction to reduce their fear of sexual intercourse, helping them to adapt to and establish a normal sex life, and achieving the purpose of treatment. Moreover, when the internal muscles of the vagina are subjected to reciprocating expansion and contraction, it can induce a neuroendocrine response in the body, promote the secretion of vaginal secretions, peristalsis of the endometrium and fallopian tube mucosa, and uterine contraction, which is beneficial for sperm to enter the uterine cavity from the vagina and then move quickly to the fallopian tube, thereby increasing the success rate of conception. The airflow entering the inflation groove 7 along the inflation tube 71 will also drive the pneumatic impeller 81 to rotate. When the massage reaches a certain number of times, the unlocking ring 821 will move with the magnetic block 822 to the bottom of the limiting slide bar 641. At this time, under the attraction between the magnetic block 822 and the limiting slide bar 641, the limiting slide bar 641 will move downward, thereby pulling the paddle 622 to rotate downward, and at this time the locking rod 621 will rotate upward and eventually disengage from the locking groove 63. At this time, under the rebound action of the force storage spring 6, the piston push block 51 will be pushed to quickly reset, thereby pushing the semen into the vagina. At this time, the semen will produce a certain accelerated injection effect under the thrust of the elastic potential energy conversion, so that the semen can smoothly enter the uterus, effectively improving the success rate of conception.

[0048] Embodiment 2:

[0049] Reference Figure 1-Figure 8 , which is basically the same as the first embodiment, and on the basis of the first embodiment, a method for assisted pregnancy through insemination is proposed, and the specific steps are as follows:

[0050] Step 1, sucking the semen in the semen collection cup 9 into the insemination tube 1: collect the semen into the semen collection cup 9, then screw the cap 3 on the mounting seat 2, and press the push-pull piece 52 to push the piston rod 5 and the piston push block 51 to move toward the bottom of the inner cavity of the insemination tube 1, and finally make the piston push block 51 plug into the arc slide 22; then insert the bottom end of the insemination tube 1 into the semen collection cup 9, so that the injection hole 21 enters the semen, and then pull the push-pull piece 52 upward to drive the piston rod 5 and the piston push block 51 to move upward, thereby generating negative pressure suction in the insemination tube 1, so that the semen in the semen collection cup 9 is sucked into the insemination tube 1, thereby completing the extraction of semen.

[0051] Step 2: slowly insert the insemination tube 1 into the vagina and simultaneously perform expansion massage on the vagina: press the elastic ball 72 so that the gas inside the elastic ball 72 enters the inflation groove 7 along the inflation tube 71, and then enters each group of expansion grooves 73 along the air guide groove 731, so that the elastic bag 4 expands outward, and then releases the elastic ball 72. Under its rebound effect, the gas will flow back, so that the elastic bag 4 will shrink and reset. This reciprocating process will cause the elastic bag 4 to continuously expand and shrink in the vagina, thereby achieving a massage effect on the vagina, thereby relaxing the sphincter and pelvic floor muscles around the vagina, so that the insemination tube 1 can be smoothly inserted into the vagina.

[0052] Step 3, push the semen in the insemination tube 1 into the vagina to complete insemination: the airflow entering the inflation groove 7 along the inflation tube 71 will also drive the pneumatic impeller 81 to rotate. When the massage reaches a certain number of times, the unlocking ring 821 will move the magnetic block 822 to the bottom of the limit slide bar 641. At this time, under the attraction between the magnetic block 822 and the limit slide bar 641, the limit slide bar 641 will move downward, thereby pulling the paddle 622 to rotate downward, and at this time the locking rod 621 will rotate upward and eventually disengage from the locking groove 63. At this time, under the rebound action of the storage spring 6, the piston push block 51 will be pushed to quickly reset, thereby pushing the semen into the vagina. At this time, the semen will produce a certain accelerated injection effect under the thrust of the elastic potential energy conversion, so that the semen can smoothly enter the uterus.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
