Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an assisted reproductive device. Background Technology

[0002] Assisted reproductive technology refers to techniques that use medical assistance to help infertile couples conceive, including artificial insemination, gamete transfer, in vitro fertilization, embryo transfer, and in vitro fertilization. For many ordinary families who cannot conceive naturally, assisted reproduction is a way to realize their "dream of having children".

[0003] For example, CN221180578U discloses an assisted reproductive device. With the cooperation of an electric push rod, a connecting rod can be moved, which in turn moves a push plate. The movement of the push plate can move a sealing ring, thus facilitating the injection of sperm into the uterus or the retrieval of eggs. The cooperation of the tube cap and the injection tube can increase the injection path, allowing sperm to be injected directly into the uterus. With the cooperation of the probe, medical staff can easily locate the cervical opening, thereby improving the accuracy of the injection.

[0004] However, this device first injects semen into the uterus, and then uses an airbag to seal the cervix. After the operation, in order to keep the airbag outside the cervix, the tube needs to be placed in the patient's body for a long time. This not only easily causes discomfort to the patient, but also makes it inconvenient for the patient to move freely, such as to meet necessary physiological needs like going to the toilet. Utility Model Content

[0027] Please see Figure 1-5As shown, an assisted reproductive device includes a fixed rod 1. The fixed rod 1 facilitates the installation and positioning of a push rod 2, allowing for smooth sliding of the push rod 2. The push rod 2 is slidably connected inside the fixed rod 1. The push rod 2 facilitates the movement of a limiting plate 7 and pushes it onto a connecting seat 34, separating the connecting seat 34 from the injection cylinder 31. An injection assembly 3 is fixedly connected to one side of the fixed rod 1. The injection assembly 3 includes an injection cylinder 31 fixedly connected to one side of the fixed rod 1. The injection cylinder 31 facilitates the collection of semen. A push rod 32 is connected inside the injection cylinder 31, facilitating connection to… The pressure plate 33 moves the rubber piston 5 within the syringe 31 when the pressure plate 33 is pushed. One end of the push rod 32 is fixedly connected to the pressure plate 33, facilitating the movement of the push rod 32. One end of the syringe 31 is connected to a connecting seat 34, allowing for easy connection and assembly. An injection catheter 35 is embedded inside the connecting seat 34, enabling direct insertion of semen into the uterus. One end of the injection catheter 35 is fixedly connected to a probe 36, allowing the doctor to observe the position of the injection catheter 35 within the patient's body. The device is positioned to facilitate accurate movement of the injection catheter 35 into the uterus. An indwelling assembly 4 is located on one side of the connecting seat 34. The indwelling assembly 4 includes a positioning plate 41, which facilitates positioning of one side of the balloon 42. The balloon 42 is connected to one side of the positioning plate 41, allowing it to be easily fixed in the patient's vagina, thus improving the stability of the balloon 45 at the cervical os. One side of the balloon 42 abuts against the positioning plate 43, which, in conjunction with the positioning plate 41, facilitates positioning of both sides of the balloon 42. One side of the positioning plate 43 is fixed... A mounting plate 44 is fixedly connected to the positioning plate 43, which facilitates the connection between the positioning plate 43 and the airbag 45. The airbag 45 is fixedly connected to one side of the mounting plate 44, which facilitates the contact of the airbag with the cervix and reduces the outflow of semen from the uterus. An air guide tube 46 is connected to one side of the airbag 45, which facilitates the inflation of the airbag 42 and the airbag 45. An air guide connector 47 is fixedly connected to the outside of the air guide tube 46, which facilitates the connection with an inflation device to inflate the airbag 42 and the airbag 45.

[0028] refer to Figure 2 and Figure 3As shown, there are two sets of fixed rods 1 and push rods 2, symmetrically arranged on both sides of the syringe 31. One end of the push rod 32 is provided with a rubber piston 5. By providing the rubber piston 5, the syringe 31 can easily absorb semen or export the semen in the syringe 31. The outer circumference of the rubber piston 5 is tightly attached to the inner wall of the syringe 31. One end of the push rod 2 is fixedly connected with a push plate 6. By providing the push plate 6, the push rod 2 can be easily moved in the fixed rod 1. The other end of the push rod 2 is fixedly connected with a limiting plate 7. By providing the limiting plate 7, the push rod 2 can be prevented from falling out of the fixed rod 1 and can move to abut against the connecting seat 34 to separate the connecting seat 34 from the syringe 31. When the push rod 2 moves in the fixed rod 1, the limiting plate 7 abuts against the connecting seat 34.

[0029] refer to Figure 2 and Figure 5 As shown, the syringe 31 is embedded inside the connecting seat 34. The connecting seat 34 has a through hole for accommodating the injection catheter 35. The injection tube at the end of the syringe 31 is embedded inside the connecting seat 34 and communicates with the injection catheter 35. A rubber stopper 8 is embedded in the through hole inside the connecting seat 34. The rubber stopper 8 has multiple fan-shaped parts inside. The rubber stopper 8 can be connected and sealed in the injection tube at the end of the syringe 31. At the same time, after the injection tube at the end of the syringe 31 is removed from the rubber stopper 8, the fan-shaped parts inside the rubber stopper 8 can slowly spring back and reposition themselves to block the through hole inside the connecting seat 34, thereby reducing the amount of semen flowing out of the vagina through the connecting seat 34.

[0030] refer to Figure 2 and Figure 4 As shown, positioning plate 1 41 and positioning plate 2 43 are located on both sides of airbag 1 42, and a connecting post 9 is fixedly connected between positioning plate 1 41 and positioning plate 2 43. The connecting post 9 can connect positioning plate 1 41 and positioning plate 2 43 to each other, keeping their positions stable. The connecting post 9 is cylindrical and passes through the inside of airbag 1 42. Airbag 2 45 is trumpet-shaped. The injection catheter 35 passes through the center of airbag 2 45, mounting plate 44, positioning plate 1 41, connecting post 9 and positioning plate 2 43. The injection catheter 35 is fixedly connected to airbag 2 45, mounting plate 44, positioning plate 1 41, connecting post 9 and positioning plate 2 43. Airbag 1 42 can be connected to the patient's vagina after inflation, thereby supporting airbag 2 45 and maintaining its stability. After airbag 2 45 is inflated, it can press against the cervix of the patient, reducing the outflow of semen from the uterus to the vagina.

[0031] refer to Figure 1As shown, a branch conduit 10 is provided on one side of the air duct 46. By providing the branch conduit 10, it is easy to connect the air duct 46 to the first airbag 42 and inflate the first airbag 42. One end of the branch conduit 10 is connected to the first airbag 42. A locking buckle 11 is provided on the side of the air duct connector 47 adjacent to the outside of the air duct 46. By providing the locking buckle 11, it is easy to lock and seal the air duct 46 to prevent the air in the first airbag 42 and the second airbag 45 from leaking out. The locking buckle 11 is slidably connected to the outside of the air duct 46.

[0032] Working principle: First, insert the syringe 31 into the rubber stopper 8 in the connector 34. Then, pull the pressure plate 33. The pressure plate 33 drives the rubber piston 5 to move inside the syringe 31 and generate negative pressure to absorb the semen. After moving the injection catheter 35 and syringe 31 into the patient's body, observe the position of the injection catheter 35 through the probe 36, so that the doctor can quickly find the patient's cervix. After the injection catheter 35 is inserted into the patient's uterus, push the pressure plate 33 to inject the semen in the syringe 31 into the patient's uterus. After the injection is completed, connect the inflation device to the air connector 47, and then inflate the first airbag 42 and the second airbag 45. The inflated airbag 42 can support the patient's vagina, thus allowing the second airbag to be inflated. Support 45 to keep the second airbag 45 stable. After the second airbag 45 is inflated, it can press against the patient's cervix to reduce the outflow of semen from the uterus. Because the air tube 46 is relatively long, a part of the air tube 46, the locking buckle 11, and the air connector 47 can remain outside the patient's vagina. Then, the locking buckle 11 is locked outside the air tube 46. Then, push the push plates 6 on both sides of the syringe 31 respectively. The push plates 6 drive the top rod 2 to move and make the limiting plate 7 press against the connecting seat 34. At this time, continue to push the push plates 6 to separate the syringe 31 from the connecting seat 34. After waiting for a certain period of time, open the locking buckle 11 to deflate the first airbag 42 and the second airbag 45. Then, slowly pull the air tube 46 to pull the first airbag 42, the second airbag 45, and the connecting seat 34 out of the patient's vagina.
