Technical Field

The application relates to the technical field of medical instruments, in particular to a suck-back prevention single-cavity ovum taking needle with a puncture protection device.

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. At present, in the stage of IVE-ET ovum taking, in order to ensure the quantity and quality of ovum taking, most of the reproductive centers mostly adopt imported single-cavity ovum taking needles, but the ovum taking needles still have more defects and shortcomings in the aspects of patient protection, process control, puncture injury protection of medical staff, negative pressure device protection, aspiration liquid protection and the like.

Disclosure of Invention

In order to overcome the problems and the defects existing in the prior art, the single-cavity ovum-taking needle has the advantages that the single-cavity ovum-taking needle has a protective effect on patients and medical care personnel, can also control the process in real time in the whole ovum-taking process, and avoids the situations of negative pressure device damage, aspiration liquid pollution and the like.

In order to achieve the above object, the technical solution of the present application is as follows:

the utility model provides a prevent that suck-back single chamber gets egg needle with puncture protection device, includes the ovum needle body of getting, first drainage tube, storage device and the negative pressure pump that connect gradually, get and be provided with puncture protection device on the ovum needle body, puncture protection device is rectangular structure, including safety cover and locking mechanical system, the both ends of safety cover have the opening, and establish on getting the ovum needle body through the opening cover, its length is less than the length of getting the ovum needle body, the safety cover is kept away from that the ovum needle body syringe needle point that gets the ovum needle point that the one end symmetry is provided with and is controlled the handle, locking mechanical system includes that one end is articulated with controlling the handle and is connected the connecting piece, set up at the reference column of the other end of connecting piece and set up first fixing base and the second fixing base on the handle, and be provided with; a first control switch is arranged on the first drainage tube; and a negative pressure pump protection device is also arranged between the storage device and the negative pressure pump.

Preferably, the storage device is of a split structure and comprises a transition bottle and a collecting bottle, the top end of the transition bottle is connected with the first drainage tube, the bottom end of the transition bottle is of an open structure and is provided with an external thread, the top opening of the collecting bottle is provided with an internal thread matched with the external thread of the transition bottle, the transition bottle is in threaded connection with the collecting bottle, and a second control switch is further arranged at the tail position of the transition bottle.

Preferably, the negative pressure pump protection device includes second drainage tube and transit bottle, and the one end and the storage device of second drainage tube are connected, and the other end is connected with the transit bottle, and the negative pressure pump passes through the negative pressure pipe to be connected with the transit bottle, is provided with third control switch on the negative pressure pipe.

Preferably, the end of the first drainage tube located in the transition bottle is tightly attached to the body of the transition bottle.

Preferably, the end of the second drainage tube positioned in the transfer bottle is tightly attached to the body of the transfer bottle.

Preferably, the body of the transfer bottle is provided with scales.

Preferably, the front end of the protective cover is of a circular arc structure.

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 in the application adopts a split structure design, the upper end is a transition bottle, the lower end is a collecting bottle, when eggs are taken, a nurse of washing hands controls the intercommunication of the transition bottle and the collecting bottle by operating a second control switch, when the collecting bottle at the lower end is fully loaded, the nurse of washing hands closes the second control switch, and the sucking liquid can be continuously collected by opening the switch after a new collecting bottle is replaced, and the sucking liquid is transferred by replacing the collecting bottle in time, so that waste and pollution of the sucking liquid caused by overflow of the sucking liquid after the storage device is fully loaded can be avoided; secondly, according to the need of negative pressure in the current link, the hand washing nurse can also correspondingly control the negative pressure in the whole egg taking process by operating the first control switch and the third 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, 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.

(4) 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.

(5) 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.

(6) 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.

(7) 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.
