Detailed Description

The utility model provides a semi-automatic follicle washing and ovum taking device which comprises an injector needle head 1, an injector injection tube 2, an injector push rod 3, a liquid inlet valve 4, a water pipe 5, a control panel 6, a limit switch 7, a pressure sensor 8, an injector piston 9, a miniature water pump 10, a battery 11, a transparent lower shell front cover 12, a stepping motor 13, a lead screw 14, a thrust rubber ring 15, an upper shell 16, a transparent lower shell rear cover 17, a coupler 18 and a motor balance frame 19. The injector injection tube 2 is fixed in the transparent lower shell front cover 12, the injector push rod 3 is fixedly connected with the injector piston 9, one end is inserted into the injector injection tube 2, the other end is fixedly connected with the motor balancing frame 19, the motor balancing frame 19 is connected with the lead screws 14 at the two ends, one end of each lead screw 14 is connected with the thrust rubber ring 15, the other end is connected with the stepping motor 13 through the shaft coupling 18, the two stepping motors have motion synchronism to ensure the balance stability of the motion of the injector push rod, the micro water pump 10 is connected with the liquid inlet valve 4 through the water tube 5, the liquid inlet valve 4 is arranged on the lower side wall of the injector injection tube 2, the limit switch 7 is arranged on the upper side wall of the injector injection tube 2 to position the upper gap and the lower gap of the injector push rod 3 in motion, the pressure sensor is arranged on the lower bottom surface of the injector injection tube 2, the battery 11 supplies power to the micro water pump 10, the stepping motor 13 and the control panel 6, and the control panel 6 is connected with the limit switch 7, A stepping motor 13, a pressure sensor 8, a micro water pump 10 and a liquid inlet valve 4.

The operation flow of the semi-automatic follicle washing and ovum taking device in the embodiment is as follows: when the disposable puncture needle is used under the aseptic condition, the transparent shell is held by hand under the guidance of ultrasonic waves, and the needle head 1 punctures to the position near a follicle through a vagina and then penetrates into the follicle cavity at an accelerated speed; when the ovum can be sucked into the injector once, the controller 6 starts to accumulate the pulse number sent to the stepping motor by opening the start button of the stepping motor 13, the stepping motor 13 drives the screw rod 14 to rotate, the motor balancing stand 19 on the screw rod 14 drives the injector push rod 3 to slowly move backwards at a uniform speed to slowly suck the target ovum, so that the ovum is prevented from being sucked too fast to cause ovum swelling or transparent band rupture to damage the ovum, the ovum and the soaking liquid are sucked into the injector injection tube 2 along with the needle head and are immediately suspended to suck, thereby the follicle in the ovary at one time is sucked, and the transparent lower cover is favorable for observing the sucking state in the injector.

When the ovum can not be sucked into the injector at one time, the follicle cavity needs to be washed, namely, the micro water pump 10 is started to start the button, the liquid inlet valve 4 is opened immediately, the stepping motor 13 is in a locked state at the moment, the micro water pump 10 injects constant-temperature follicle washing liquid into the follicle through the needle head 1 for washing, the pressure sensor 8 in the injector injection tube 2 monitors the pressure in the tube, the controller 6 calculates the follicle tension, an emergency starting point is set, the washing is stopped, the washing speed is generally controlled to be 4-5 seconds, 5 milliliters of follicle washing liquid is injected at a constant speed, after the washing is finished, the micro water pump 10 is closed to stop the button, the ovum sucking action is repeated, and the ovum sucking is finished.
