Description
Technical field
The utility model relates to a kind of medical apparatus field, particularly to a kind of preventing hand pricking disposable syringe with protection formula needle cap.
Background technology
Disposable syringe is widely used in medicinal work, serves indispensable effect.The needle cap of the syringe owing to commercially returning is directly to be locked on pintle, when either doctor or nurse use clinically, often because sleeve structure designed between common pintle and needle cap is excessively tight, it is difficult to open, so can draw back one's hand when causing firmly excessive, and imprudence is pricked in one's hands, there is very big medical security risks.
In presently disclosed patent document, disclosing a kind of syringe, it is, at the outer wall of pintle, the described inwall protecting needle cap is provided with the screw thread being mutually matched.It is prevented to a certain extent when medical personnel pull out needle cap because of overexert and by needle stick injury, but owing to pintle is to be sleeved on nipple, when pintle with when protecting needle cap overtorquing, during Unscrew needle cap, pintle rotates together also with protecting needle cap, be difficult to by pintle with protect needle cap and open and separate.
Content of the invention
The technical problems to be solved in the utility model is: provide one when can effectively prevent medical personnel from pulling out needle cap because of overexert and by needle stick injury; quickly needle cap can be taken off from pintle again, the convenient and practical preventing hand pricking disposable syringe with protection formula needle cap, solve above-mentioned prior art exist problem.
The technical scheme solving above-mentioned technical problem is: a kind of preventing hand pricking disposable syringe with protection formula needle cap; including needle cap, pintle and nipple; described needle cap end is provided with internal thread; pintle end is provided with external screw thread; needle cap is threaded connection with pintle, and described pintle is sleeved on nipple and is fixed by bayonet socket.
Described bayonet socket includes the positioning ring set being provided with on N number of boss that pintle top is provided with and nipple, and locating ring puts and has N number of groove coordinating with boss, and boss is positioned at groove clamping, and the value of N is 1～6.
The utility model in needle cap end, pintle end be provided with screw thread, needle cap is threaded connection with pintle, pintle and syringe nipple pass through bayonet connection simultaneously, i.e. pintle top is provided with boss, nipple is provided with the groove coordinating with boss, after pintle is fixed by bayonet socket with nipple, even if when pintle and when pulling it green of needle cap, due to the fixation of bayonet socket, during rotating needle cap, pintle will not rotate, therefore quickly can take off needle cap from pintle.
The beneficial effects of the utility model are: convenient and practical, user only need to rotate when fetching needle cap and turn, set bayonet socket is to assist completing of operation, the chance accidentally pricked the hand is made to greatly reduce, improve the medical safety of health care workers, it also avoid needle cap simultaneously and rotate the situation generation being difficult to take off together with pintle, be conducive to improving operating efficiency.
Below, in conjunction with the accompanying drawings and embodiments the technical characteristic of a kind of preventing hand pricking disposable syringe with protection formula needle cap of the utility model is further described.
