Description

Technical Field

[0001] The invention relates to the technical field of reproductive medicine medical equipment, and in particular to an artificial insemination transplantation tool. Background Art

[0002] Artificial insemination refers to an assisted reproductive technology that artificially injects sperm into the female reproductive tract, allowing the sperm to pass through the uterine cavity to the fallopian tube and combine with the egg to form a fertilized egg. The fertilized egg returns to the uterine cavity under the peristalsis of the fallopian tube and the swing of cilia, and then implants and becomes pregnant. After artificial insemination, the patient is generally required to lie quietly for half an hour, one is to prevent the spillage of semen, and the other is to allow the semen to swim into the fallopian tube as much as possible. There are many ways and channels for artificial insemination to deliver sperm to different parts of the female reproductive tract to help sperm reach the female reproductive tract smoothly. In the existing technology, most of them use a combination of a speculum and a pipette to assist in completing artificial insemination.

[0003] However, the above-mentioned artificial insemination and transplantation tools still have certain disadvantages in certain usage situations.

[0004] 1. The overall structural design of the above-mentioned artificial insemination transplantation tool is relatively simple. Since the infusion hose needs to be inserted into the female's cervix to complete fertilization, a longer infusion hose is required, and the infusion hose needs to have a certain degree of flexibility to ensure its curvature. This makes it difficult for the infusion hose to enter the cervix through the cervical opening, and the operation is more troublesome. In addition, the infusion hose is likely to touch the inner wall of the reproductive tract, causing the infusion hose to bring the liquid on the inner wall of the reproductive tract into the cervical opening, which is easy to cause infection and cause gynecological diseases.

[0005] 2. The above-mentioned artificial insemination transplantation tool cannot prevent the overflow of semen. After completing the artificial insemination steps, when the infusion hose is taken out from the female reproductive tract, semen is likely to flow out from the cervix, greatly reducing the success rate of sperm and egg combination, and the artificial insemination effect is not ideal enough.

[0006] Therefore, a more professional artificial insemination transplantation tool is urgently needed to solve the above-mentioned defects. Summary of the invention

[0014] In a preferred embodiment of the present invention, a plurality of assembly holes are provided at one end of the pipette, and baffle rods are provided in each of the assembly holes.

[0018] In a preferred embodiment of the present invention, one side of the elastic airbag is fixedly connected to a reel-in rope, the other end of the reel-in rope is wound around a reel-in wheel, and the reel-in wheel is disposed inside the pipette cylinder.

[0019] The present invention solves the defects existing in the background technology and has the following beneficial effects.

[0020] (1) The present invention protects the infusion hose by an arc-shaped cover plate, so that one end of the infusion hose is always wrapped by the arc-shaped cover plate before reaching the cervical opening. When the front end of the pipette reaches the cervical opening, the arc-shaped cover plate is opened to allow the infusion hose to slowly enter the cervix, effectively preventing the infusion hose from touching the inner wall of the reproductive tract and improving the prevention effect of gynecological diseases. In addition, the infusion hose is arranged in the pipette, which reduces the length of the infusion hose. The infusion hose will not be bent during the process of entering the cervix, making it easier to enter the cervix and the operation process more precise.

[0021] (2) The elastic airbag provided at the end of the pipette of the present invention pushes the piston baffle to move toward the front end of the pipette, and the gas in the first closed cavity enters the elastic airbag through the second closed cavity, so that the elastic airbag expands and blocks the cervical opening, effectively preventing the semen from overflowing after being injected into the cervix, and effectively improving the success rate of sperm and egg combination. At the same time, by utilizing the friction between the elastic airbag and the reproductive tract, the elastic airbag remains at the cervical opening when the pipette leaves, and the elastic airbag attached to the outer wall of the pipette will continue to expand and fit each other, continue to block the cervical opening, prevent the semen from overflowing from the cervical opening, and make the semen stay in the cervix as much as possible, further improving the success rate of sperm and egg combination.

[0022] (3) In the present invention, when the gas in the first closed cavity passes through the second closed cavity and enters the elastic airbag, the gas in the first closed cavity simultaneously supports the piston sliding block after entering the second closed cavity, and the piston sliding block supports the force plate through the push rod, thereby opening the arc cover plate, that is, the expansion of the elastic airbag and the opening of the arc cover plate are carried out simultaneously, which effectively improves work efficiency.

[0023] (4) In the present invention, after the piston baffle contacts one side, under the action of the fixed piston column, the infusion hose leaves the piston baffle and continues to move until the engaging groove and the baffle rod engage with each other, so that the infusion hose can extend as far as possible from the pipette tube into the cervix. On the other hand, after the fixed piston column contacts the piston baffle, the push block will push the assembly block out, so that the movable piston column can smoothly push the semen in the liquid storage bottle through the piston baffle and the infusion hose into the uterine cavity.

[0024] (5) The present invention prevents the gas in the elastic airbag from leaking out by setting a one-way air valve on the inner side of the elastic airbag, so that the elastic airbag is always kept in an expanded state, effectively ensuring that the elastic airbag can continue to block the cervical opening. On the other hand, the elastic airbag is connected with a reel to facilitate the elastic airbag to be pulled out of the reproductive tract after a period of time, thereby avoiding the elastic airbag from being retained in the reproductive tract for a long time and causing discomfort to the patient. The overall operation process is safer and the operation process is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0039] like Figure 1 , Figure 2 and Figure 3As shown, an artificial insemination transplantation tool comprises: a propulsion assembly and a protection assembly arranged on a pipette 1, the propulsion assembly comprising: a liquid storage bottle 2 detachably arranged at one end of the pipette 1, a fixed piston column 3 is arranged at the front end of the liquid storage bottle 2, a movable piston column 4 is arranged at the rear end of the liquid storage bottle 2, the front end of the liquid storage bottle 2 is embedded in the pipette 1, an infusion hose 5 is arranged in the pipette 1, a piston baffle 6 is arranged at one end of the infusion hose 5 near the liquid storage bottle 2, the piston baffle 6 and the pipette 1 form a first closed cavity 7, and a protection assembly is arranged at the end of the pipette 1.

[0040] like Figure 4 and Figure 6 As shown, the protection component includes: a second closed cavity 8 arranged at the end of the pipette 1, the second closed cavity 8 is connected to the first closed cavity 7 through a ventilation tube 9, an elastic air bag 10 is sleeved on the outer peripheral side of the end of the pipette 1, a plurality of one-way air valves 11 are arranged on the inner side of the elastic air bag 10, the elastic air bag 10 is connected to the second closed cavity 8, a piston sliding block 12 is arranged in the second closed cavity 8, the piston sliding block 12 is movably connected to an arc cover plate 14 through a plurality of push rods 13, and the arc cover plate 14 is hingedly connected to the end of the pipette 1.

[0041] In a preferred embodiment of the present invention, the infusion hose 5 is protected by the arc cover plate 14, so that one end of the infusion hose 5 is always wrapped by the arc cover plate 14 before reaching the cervical opening. When the front end of the pipette 1 reaches the cervical opening, the arc cover plate 14 is opened to allow the infusion hose 5 to slowly enter the cervix, effectively preventing the infusion hose 5 from touching the inner wall of the reproductive tract, thereby improving the prevention effect of gynecological diseases. In addition, the infusion hose 5 is arranged in the pipette 1, which reduces the length of the infusion hose 5, and does not bend during the process of entering the cervix, making it easier to enter the cervix, and the operation process is more accurate.

[0042] like Figure 5 and Figure 6 As shown, by the elastic airbag 10 arranged at the end of the pipette 1, when the piston baffle 6 is pushed to move toward the front end of the pipette 1, the gas in the first closed cavity 7 enters the elastic airbag 10 through the second closed cavity 8, so that the elastic airbag 10 expands and blocks the cervical opening, effectively preventing the semen from overflowing after being injected into the cervix, and effectively improving the success rate of sperm and egg combination. At the same time, by utilizing the friction between the elastic airbag 10 and the reproductive tract, the elastic airbag 10 remains at the cervical opening when the pipette 1 leaves, and the middle part of the elastic airbag 10 attached to the outer wall of the pipette 1 will continue to expand and fit each other, completely blocking the cervical opening, preventing the semen from overflowing from the cervical opening, and allowing the semen to be retained in the cervix as much as possible, further improving the success rate of sperm and egg combination.

[0043] In a preferred embodiment of the present invention, a flexible gasket 41 is arranged between the arc-shaped cover plate 14 and the pipette cylinder 1, and the flexible gasket 41 is made of silicone material, so that the arc-shaped cover plate 14 and the pipette cylinder 1 are tightly connected, and at the same time, the relative movement of the arc-shaped cover plate 14 and the pipette cylinder 1 is not affected, so as to avoid the arc-shaped cover plate 14 from scratching the inner wall of the reproductive tract when moving, and at the same time, the elastic airbag 10 is smoother and easier to fall off.

[0044] like Fig. 9 As shown, a piston ball 34 is provided at one end of the infusion hose 5 near the piston baffle 6, and the piston ball 34 is fixed to the inner side of the infusion hose 5 by a plurality of connecting springs 35. After the piston baffle 6 contacts the side of the first closed cavity 7, under the pushing action of the fixed piston column 3, the gas pressure will still produce a certain supporting force on the infusion hose 5, thereby pushing the infusion hose 5 as a whole to move toward the front end of the pipette cylinder 1 until the engaging groove 33 and the blocking rod 30 are engaged with each other.

[0045] like Figure 6 As shown, a mounting groove 25 is provided at the end of the pipette 1, and a rotating shaft is provided in the mounting groove 25. The rotating shaft is connected to the side of the mounting groove 25 through a torsion spring 26. An arc-shaped cover plate 14 is fixedly sleeved on the rotating shaft. A force plate 15 is integrally provided at one end of the arc-shaped cover plate 14. The force plate 15 and the push rod 13 are connected with each other. When the gas in the first closed cavity 7 passes through the second closed cavity 8 and enters the elastic airbag 10, the gas in the first closed cavity 7 simultaneously supports the piston sliding block 12 after entering the second closed cavity 8. The piston sliding block 12 supports the force plate 15 through the push rod 13, so that the arc-shaped cover plate 14 is opened, that is, the expansion of the elastic airbag 10 and the opening of the arc-shaped cover plate 14 are carried out simultaneously, which effectively improves the working efficiency.

[0046] like Figure 4 and Figure 6 As shown, a plurality of assembly holes are provided at one end of the pipette 1, and baffle rods 30 are provided in the plurality of assembly holes. A connecting rope 31 is provided at the end of the baffle rod 30, and the other end of the connecting rope 31 is fixedly connected to a rotating ring 32, and the rotating ring 32 is movably sleeved on the circumferential side of the pipette 1; a clamping groove 33 is provided at one end of the infusion hose 5 close to the piston baffle 6, and the baffle rod 30 and the clamping groove 33 cooperate with each other. In the initial state, the baffle rod 30 extends out of the assembly hole under the action of a spring, and the baffle rod 30 can be clamped with the clamping groove 33. By rotating the rotating ring 32, the baffle rod 30 can be pulled into the assembly hole, thereby controlling the baffle rod 30 to loosen the infusion hose 5. It should be noted that the part of the infusion hose 5 located in the clamping groove 33 is made of a harder material, preferably medical PVC material.

[0047] In a preferred embodiment of the present invention, after the piston baffle 6 contacts one side, under the action of the fixed piston column 3, the infusion hose 5 leaves the piston baffle 6 and continues to move until the engaging groove 33 and the baffle rod 30 engage with each other, so that the infusion hose 5 extends as far as possible out of the pipette 1 into the cervix. On the other hand, after the fixed piston column 3 contacts the piston baffle 6, the top block 37 will push out the assembly block 38, so that the movable piston column 4 can smoothly push the semen in the liquid storage bottle 2 through the piston baffle 6 and the infusion hose 5 into the uterine cavity.

[0048] like Figure 7 As shown, a transition cavity 27 is arranged in the middle part of the fixed piston block 28, and a piston block 28 is arranged in the transition cavity 27. The piston block 28 is connected to the side of the transition cavity 27 through a return spring 29. Through the cooperation between the piston block 28 and the transition cavity 27, when the semen in the liquid storage bottle 2 is not subjected to the pushing pressure of the moving piston column 4, the semen in the liquid storage bottle 2 will not flow out, thereby playing a certain sealing role on the liquid storage bottle 2. When the semen in the liquid storage bottle 2 begins to be subjected to the pushing pressure of the moving piston column 4, the piston block 28 moves relative to the transition cavity 27, connects the liquid storage bottle 2 and the piston baffle 6, and further connects the infusion hose 5.

[0049] In a preferred embodiment of the present invention, a plurality of push rods 36 are arranged on the side of the fixed piston column 3, and a push block 37 is arranged at the end of the plurality of push rods 36. An assembly block 38 is arranged in the middle of the piston baffle 6. The assembly block 38 is connected to the piston baffle 6 through a plurality of tension springs 39, and the push block 37 cooperates with the assembly block 38. When the fixed piston column 3 contacts the piston baffle 6, the push block 37 pushes the assembly block 38 to move relative to the piston baffle 6, further connecting the inside of the liquid storage bottle 2 to the infusion hose 5, connecting the liquid storage bottle 2 and the infusion hose 5, and the semen in the liquid storage bottle 2 can smoothly enter the infusion hose 5, and thus smoothly enter the uterine cavity.

[0050] like Fig.10 As shown, a one-way air valve 11 is arranged on the inner side of the elastic airbag 10. The one-way air valve 11 is formed by splicing a plurality of arc-shaped fan pieces, which all protrude outward and are recessed inward. The one-way air valve 11 will open to allow gas to enter under the action of external air pressure, but will not open due to excessive internal air pressure, thereby effectively preventing the gas in the elastic airbag 10 from leaking out, always maintaining an expanded state, and effectively ensuring that it can continue to block the cervical opening.

[0051] In a preferred embodiment of the present invention, one side of the elastic airbag 10 is fixedly connected to the winding rope 40, and the other end of the winding rope 40 is wound on the winding wheel. The winding wheel is arranged inside the pipette tube 1. The winding rope 40 is used to connect the elastic airbag 10, so that the elastic airbag 10 can be pulled out of the reproductive tract after a period of time to avoid being retained in the reproductive tract for a long time and causing discomfort to the patient. The overall operation process is safer and the operation process is more convenient.

[0052] like Figure 8As shown, a driving handle 16 is provided at the tail end of the pipette 1, a pressing rod 17 is provided at one side of the driving handle 16, a primary piston plate 18 is provided inside the driving handle 16, the pressing rod 17 is connected to the primary piston plate 18, the primary piston plate 18 is connected to the secondary piston plate 19 through a plurality of primary support springs 23, and the secondary piston plate 19 is connected to the inner side of the driving handle 16 through a plurality of secondary support springs 24. The primary piston plate 18 and the secondary piston plate 19 form a first air pressure chamber 20, the secondary piston plate 19 and the inner side of the driving handle 16 form a second air pressure chamber 21, a stopper 22 is provided on the side of the secondary piston plate 19 located in the first air pressure chamber 20, a matching hole is provided on the surface of the stopper 22, the matching hole is connected to a plurality of air pressure telescopic rods 44 through a first air pressure tube 42, and the plurality of air pressure telescopic rods 44 are connected to the tail end of the liquid storage bottle 2; the second air pressure chamber 21 is connected to the inside of the liquid storage bottle 2 through a second air pressure tube 43.

[0053] The working principle of the present invention is as follows: human body lubricating oil is applied to the pipette 1, the elastic airbag 10 and the arc-shaped cover plate 14, so that the pipette 1 enters the female reproductive tract until the arc-shaped cover plate 14 contacts the cervical opening; the pressing rod 17 is pushed to squeeze the primary piston plate 18, and the primary piston plate 18 squeezes the first air pressure chamber 20, and the gas in the first air pressure chamber 20 passes through the first air pressure tube 42 and enters the air pressure telescopic rod 44, and the air pressure telescopic rod 44 is extended to drive the liquid storage bottle 2 to move forward as a whole, and the fixed piston column 3 located at the front end of the liquid storage bottle 2, the fixed piston column 3 uses air pressure to hold the piston baffle 6 , until the piston baffle 6 contacts one end face of the first closed cavity 7, the piston baffle 6 squeezes the gas in the first closed cavity 7 into the second closed cavity 8, the air pressure in the second closed cavity 8 increases, and a part of the gas enters the elastic airbag 10, causing the elastic airbag 10 to expand and block the cervical opening. At the same time, under the action of the air pressure in the second closed cavity 8, the piston sliding block 12 moves forward, and supports multiple force plates 15 at the same time through the push rod 13. The force plates 15 rotate clockwise, driving the corresponding arc cover plates 14 to open, that is, the expansion of the elastic airbag 10 and the opening of the arc cover plates 14 are carried out simultaneously.

[0054] Continue to push the pressing rod 17, press the fixed piston column 3 gradually close to the piston baffle 6, and further push the infusion hose 5 out of the pipette 1 until the clamping groove 33 on the infusion hose 5 cooperates with the baffle rod 30, and the infusion hose 5 enters the cervix to the maximum extent. At the same time, the top block 37 pushes the assembly block 38 away from the piston baffle 6. At this time, the first-level piston plate 18 contacts the baffle 22, and the air pressure in the first air pressure chamber 20 remains unchanged. Continue to push the pressing rod 17 to start squeezing the secondary piston plate 19, and the gas in the second air pressure chamber 21 enters the liquid storage bottle 2 through the second air pressure tube 43, so that the movable piston column 4 gradually pushes the semen in the liquid storage bottle 2 into the infusion hose 5, and enters the cervix through the infusion hose 5 to complete artificial insemination; pull the driving handle 16 to pull out the pipette 1 as a whole, and use the friction between the elastic air bag 10 and the reproductive tract to leave the elastic air bag 10 at the cervical opening when the pipette 1 leaves, and at the same time, the elastic air bag 10 attached to the outer wall of the pipette 1 will continue to expand and fit each other, and continue to block the cervical opening. When the pipette 1 leaves the elastic air bag 10, the winding rope 40 gradually stretches until the pipette 1 leaves the reproductive tract, leaving one end of the winding rope 40 outside the reproductive tract, so that the elastic air bag 10 is conveniently pulled out of the reproductive tract after a period of time.

[0055] It should be noted that the total elastic coefficient of the secondary support springs 24 located in the second air pressure chamber 21 is greater than the total elastic coefficient of the primary support springs 23 located in the second air pressure chamber 21, and before the primary piston plate 18 contacts the stopper 22, the secondary piston plate 19 is always in a stationary state relative to the driving handle 16. On the other hand, in the initial state, the elastic airbag 10 is attached to the circumferential side of the front end of the pipette 1 as a whole, and the multiple arc-shaped cover plates 14 are in a closed state. When the primary piston plate 18 contacts the stopper 22, the elastic airbag 10 is in an expanded state, and the multiple arc-shaped cover plates 14 are in an open state. The clamping groove 33 on the infusion hose 5 cooperates with the stopper rod 30, and the infusion hose 5 enters the cervix to the maximum extent. The top block 37 holds the assembly block 38 away from the piston baffle 6, so that the liquid storage bottle 2 is connected to the inside of the cervix through the piston baffle 6 and the infusion hose 5.

[0056] It should be noted that the second air pressure tube 43 is made of rubber material and has a certain deformation ability, so that the second air pressure tube 43 can always maintain connection with the liquid storage bottle 2 during the overall movement of the liquid storage bottle 2.
