Description
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.

when the collection bottle 32 in the storage device 3 is full, the medical staff will close the second control switch 8, thereby, a new collection bottle 32 is replaced to collect the suction liquid, and the suction liquid sucked out by the first drainage tube 2 is temporarily stored in the transition bottle 31, when the liquid in the transition bottle 31 reaches a certain amount, it may be sucked into the negative pressure pump 4 along with the tube, causing damage to the negative pressure pump 4, but during the entire aspiration process, in order to improve the working efficiency and shorten the egg taking time, the negative pressure pump 4 is not selected to be switched off, therefore, in order to protect the negative pressure pump 4, the present application also provides a negative pressure pump protection device 7 between the negative pressure pump 4 and the storage device 3, when the liquid in the transition bottle 31 reaches a certain amount, it will enter the second drainage tube 71, and the second drainage tube 71 enters the transfer bottle 72 for storage, and the transfer bottle 72 can adopt a container with larger volume.
Further definition with respect to the first draft tube 2 and the second draft tube 71:
the end of the first drainage tube 2 located in the transition bottle 31 is tightly attached to the body of the transition bottle 31.
The end of the second drainage tube 71 located in the transfer bottle 72 is tightly attached to the body of the transfer bottle 72.
Two drainage tubes in this application are equallyd divide and are hugged closely corresponding body respectively, consequently, 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 down cause the possibility of damage to the ovum cell.
Further definition with respect to the transfer bottle 72:
the body of the transfer bottle 72 is provided with a scale 11. The scale 11 of body can make things convenient for medical personnel to carry out real time monitoring to the interior liquid of bottle.
Further definition with respect to the boot 51:
the front end of the protective cover 51 is of a circular arc structure. In this application, the front end of safety cover 51 is the design of circular arc line type, and consequently, safety cover 51's tip is more level and smooth, can avoid getting the ovum in-process, and safety cover 51 produces unnecessary injury to the patient.
In the description of the present application, it is to be understood that the terms "center", "longitudinal", "lateral", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are used merely for convenience in describing the present application and for simplifying the description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed in a particular orientation, and be operated, and therefore should not be construed as limiting the scope of the present application.
The foregoing is directed to embodiments of the present invention, which are not limited thereto, and any simple modifications and equivalents thereof according to the technical spirit of the present invention may be made within the scope of the present invention.
