Description

Technical Field

[0001] The present invention relates to the technical field of artificial insemination instruments, and in particular to an artificial insemination device for reproductive medicine. Background Art

[0002] Artificial insemination refers to the use of non-sexual intercourse to inject selected sperm into the female reproductive tract (vagina or cervix or uterine cavity), which is an assisted reproductive technology. The artificial insemination currently performed is intrauterine artificial insemination. At present, the injection of sperm through an artificial insemination catheter will cause some sperm to remain, and some sperm will overflow from the uterine cavity when the artificial insemination tube is taken out. For example, when the artificial insemination tube is injecting sperm, the piston inside the syringe has been pushed to the very end, but there may still be residues inside the syringe and the catheter. At this time, it is not appropriate to reconnect or aspirate. Therefore, those skilled in the art have redesigned the syringe to achieve a more thorough injection of residual semen into an artificial insemination device for reproductive medicine. Summary of the invention

[0036] Refer to the instruction manual Figure 6 As shown: the front end port of the syringe 11 is fixedly connected with an injection nozzle 112, and a branch pipe 111 is connected to the right side surface of the injection nozzle 112, and a rotating shaft 19 is rotated inside the branch pipe 111, and the end of the rotating shaft 19 located in the inner cavity of the injection nozzle 112 is fixedly connected with a silicone ball 17, and the end of the rotating shaft 19 located outside the branch pipe 111 is fixedly connected with a knob 110.

[0037] Refer to the instruction manual Figure 6As shown: the outer surface of the silicone ball 17 is in close contact with the inner cavity side wall of the injection nozzle 112, a round hole for the branch tube 111 to pass through is opened on the right surface of the injection nozzle 112, and a round hole for the air supply tube 14 to pass through is opened on the left surface of the injection nozzle 112.

A round hole 113 coaxial with the injection nozzle 112 and the syringe 11 is opened in the central position of the silicone ball 17, and the two ports of the round hole 113 are in close contact with the inner cavity side wall of the injection nozzle 112 after the silicone ball 17 is turned 90 degrees. The front end port of the injection nozzle 112 is connected to the rear end end of the insemination catheter 15 through a joint.

[0038] According to the above-mentioned preferred technical solution, the workflow of the technical solution is described as follows:

[0039] After rotating the knob 110 counterclockwise by 90 degrees, the limit rod 18 changes from the original horizontal position to the vertical position. At this time, the silicone ball 17 is turned 90 degrees under the pulling and rotating action of the knob 110 and the rotating shaft 19, and the port of the round hole 113 changes from the original contact state with the inner wall of the injection nozzle 112 to the coaxial position with the injection nozzle 112. In addition, the joint through which the air supply pipe 14 passes on the left side of the injection nozzle 112 is blocked, and the piston 12 and the piston rod 13 are pulled away from the syringe 11, and the semen to be injected is drawn into the inner cavity of the syringe 11 under the action of negative pressure.

[0040] Then, the piston 12 and the piston rod 13 are pushed in the opposite direction, forcing the semen in the syringe 11 to enter the insemination catheter 15 along the syringe 11, the circular hole 113 and the injection nozzle 112, and then injected into the human body through the insemination catheter 15. After the piston rod 13 moves to the end of the syringe 11, the joint of the air supply pipe 14 on the side of the injection nozzle 112 is connected to the air pipe 14, and the knob 110 is rotated 90° clockwise to make the two ports of the circular hole 113 inside the silicone ball 17 contact with the inside of the injection nozzle 112 again, thereby isolating the injection nozzle 112 space from the syringe 11 space.

[0041] At this time, the driving motor 27 is used to drive the turbofan 23 to rotate inside the lower end cover 22 and the upper end cover 24. After the air is filtered by the filter plate 32 and the air filter element 33, it is transported to the inside of the trachea 14 by the air outlet pipe 25, and then the trachea 14 guides the air into the front area of ​​the inner cavity of the injection nozzle 112, and the airflow is used to discharge the semen remaining in the injection nozzle 112 and the insemination catheter 15.

[0042] The turbofan 23 driven by the above-mentioned drive motor 27 can also be replaced by a manual crank, that is, the crank is shaken to drive the turbofan 23 to rotate inside the lower end cover 22 and the upper end cover 24. After the air is filtered by the filter plate 32 and the air filter element 33, it is transported to the inside of the trachea 14 by the air outlet pipe 25, and then the trachea 14 guides the air into the front side area of ​​the inner cavity of the injection nozzle 112, and the airflow is used to discharge the semen remaining in the injection nozzle 112 and the insemination catheter 15.
