Description

Disposable self-destruction type needlestick prevention dispensing device Technical Field The utility model relates to the technical field of medical equipment, in particular to a disposable self-destroying type needlestick preventing medicine dispenser. Background In the dispensing process, the dispenser or the injector is repeatedly used, residual liquid medicine in the instrument cannot be ensured, different medicines can be extracted by repeatedly using the dispenser, physical and chemical reactions such as neutralization, hydrolysis, failure damage and the like can occur, even the patient can be caused to have drug anaphylactic reaction, and infusion particles can be accumulated by repeatedly using the dispenser, the infusion particles refer to non-metabolic particle impurities in infusion liquid, when the needle head repeatedly penetrates through the rubber bottle stopper of the medicine bottle, the infusion particles are more likely to be caused, and if a large amount of liquid of insoluble particles is infused by the patient, phlebitis, vascular embolism, infarction, granuloma, heat source reaction and the like can be caused. To this end, the present inventors have found a method for solving the above-mentioned problems through beneficial studies and studies, and the technical solutions to be described below are made in this context. Disclosure of utility model The utility model aims to solve the technical problems of the prior art by providing a disposable self-destroying type needlestick preventing medicine dispenser to solve the problems The technical problems to be solved by the utility model can be realized by adopting the following technical scheme: A disposable self-destructive anti-needlestick dispenser, comprising: A slidable upper cover; An upper needle arranged at one end of the upper cover and used for puncturing the penicillin bottle; The elastic piece is arranged on the upper cover and used for exciting self-destruction to the upper needle; a lower cover for sliding fit of the upper cover; A lower needle arranged at one end of the lower cover and used for puncturing another penicillin bottle; And the recovery cavity is arranged on the lower cover and used for recovering the upper needle head. When the medical device is used, the upper needle of the upper cover pierces the upper penicillin bottle, the lower needle of the lower cover pierces the lower penicillin bottle, then the liquid medicine in the upper penicillin bottle flows into the lower needle through the upper needle to enter the lower penicillin bottle for contact mixing, after the mixing is finished, the upper cover is slid, the upper needle is stimulated to be pushed to form a self-destruction effect when the position of the elastic piece reaches the recovery needle cavity of the lower cover, at the moment, the upper penicillin bottle is aligned to the waste medical device storage box, when the self-destruction is stimulated, the upper penicillin bottle automatically falls due to the recovery of the upper needle, after the self-destruction is stimulated, the liquid medicine is gently shaken and mixed, and the mixed liquid medicine is extracted by a nurse. In a preferred embodiment of the utility model, the other end of the upper cover is provided with a handle which is convenient to push and pull. In a preferred embodiment of the utility model, one end of the upper cover is also provided with a platform for the penicillin bottle to be horizontally placed and positioned at the puncture position of the upper needle. In a preferred embodiment of the utility model, the other end of the lower cover is provided with a luer fitting for the syringe to be docked. In a preferred embodiment of the utility model, one end of the lower cover is further provided with a sealing assembly. In a preferred embodiment of the utility model, the sealing assembly is an O-ring fitted over the lower cover. In a preferred embodiment of the utility model, the bottom of the lower cover is provided with a hoop for fixing the penicillin bottle. In a preferred embodiment of the utility model, the elastic member is a spring. In a preferred embodiment of the present utility model, the upper needle and the lower needle are molded by non-metal injection. The utility model has the beneficial effects that the needle is prevented from being pierced by disposable use and adopting the nonmetallic needle to replace the metallic needle, and when the utility model is used, a nurse pushes the upper cover and then excites the spring, the upper needle is sprung into the recovery cavity of the lower cover through the spring, meanwhile, the nurse can extract mixed liquid medicine by using the injector, and the O-shaped sealing ring can also well play a sealing role between the upper cover and the lower cover.
