Background

The IVF-ET (In Vitro Fertilization-Embryo Transfer) In Vitro Fertilization-Embryo Transfer technology is also called tube infant, is one of the main technical means for solving infertility In contemporary medicine, and refers to a technology for achieving the purpose of conception by taking out ovum and sperm from human body, fertilizing In Vitro, developing into Embryo, and then transferring into mother uterus.

In the whole complete cycle of IVF-ET, the egg taking link behind the trigger becomes one of the key links in the whole process, because the number of the taken eggs in the link directly influences the number of the embryos cultured in the subsequent laboratory embryo culture link. However, in the process of ova aspiration, the number and quality of ova obtained finally are greatly reduced due to the poor growth of follicles of patients, too few mature follicles and empty follicles caused by various factors, and meanwhile, ova are difficult to aspirate because some ova do not flow down along with follicular fluid and are attached to ovarian tissues, and in the operation process of most reproductive centers, many defects and deficiencies still exist in the aspects of patient protection, process control, puncture protection of medical staff, protection of negative pressure devices, protection of aspiration fluid and the like.

The beneficial effect of this application:

(1) this application can make things convenient for the nurse of washing hand to carry out real time control to the whole link of getting the ovum on the operating table when using. Firstly, the storage device is in a split type design, the upper end of the storage device is a transition bottle, the lower end of the storage device is a collection bottle, a hand washing nurse achieves control over intercommunication of the transition bottle and the collection bottle by operating a third control switch, when the collection bottle at the lower end is fully loaded, the hand washing nurse turns off the third control switch, and turns on the switch after replacing a new collection bottle, so that the suction liquid can be continuously collected, and the suction liquid can be transferred by replacing the collection bottle in time, so that waste and pollution of the suction liquid caused by overflow of the suction liquid after the storage device is fully loaded can be avoided; secondly, according to whether the negative pressure is needed or not in the current link, the hand washing nurse can also correspondingly control the negative pressure in the whole egg taking process by operating the second control switch and the fourth control switch.

(2) In this application, get the ovum needle body and go up the cover and be equipped with telescopic puncture protection device, puncture protection device comprises safety cover and locking mechanical system. In-process that the ovum needle body of getting that will overlap at medical personnel was put in patient's vagina with the cover, the syringe needle point-end parcel that the ovum needle body will be got to the safety cover is inside, consequently, under the guard action of safety cover, the syringe needle point-end of getting the ovum needle body can not stab patient's vagina because of the operation is not good, so not only safe in utilization has also alleviateed patient's injured probability simultaneously, and the device is when not using, medical personnel can also be protected to the safety cover, prevent that medical personnel from being stabbed by the syringe needle point-end of getting the ovum needle body.

(3) In this application, be provided with washing unit on the first drainage tube, under washing unit's effect, can wash down the egg cell of attaching to on the ovary tissue to in being inhaled the collecting bottle along with the suction liquid together, consequently, can be as much as possible obtain the ovum, promote the success rate in the supplementary reproduction laboratory fertilization link.

(4) In this application, adopt threaded connection's mode to dismantle between transition bottle and the receiving flask and be connected, consequently, in the in-service use process, it is more convenient and swift when medical personnel change the receiving flask.

(5) In this application, be provided with negative pressure pump protection device between storage device and the negative pressure pump, negative pressure pump protection device comprises transfer bottle and second drainage tube, thereby the design of transfer bottle can avoid causing negative pressure machine to damage because the staff observes the suction liquid that leads to not in place and gets into negative pressure machine along with the pipeline, suction liquid pollutes and patient infects etc. simultaneously can also avoid because the suction liquid that leads to after the receiving flask is fully loaded overflows, thereby the egg cell that leads to runs off.

(6) In this application, the body of transition bottle and the body of transfer bottle are hugged closely respectively to first drainage tube and second drainage tube, can play buffer liquid velocity of flow, control flow direction to reach the effect of drainage, can prevent that liquid from directly leaving the possibility that causes the splash from the eminence, also can reduce simultaneously because liquid from eminence splash and cause the possibility of damage to the egg cell down.

(7) In this application, the design has the scale on the body of well commentaries on classics bottle, consequently, can make things convenient for medical personnel to carry out real time monitoring to liquid in the bottle.

(8) In this application, the front end of safety cover is the design of circular arc line type, and consequently, the tip of safety cover is more level and smooth, can avoid getting the ovum in-process, and the safety cover produces unnecessary injury to the patient.

(9) In this application, the syringe inner wall is provided with the round dog along circumference near afterbody position department, can prevent effectively that the piston part of push rod from being pulled out the syringe by the operator.
