Description
Technical field:
This utility model relates to technical field of medical, a kind of specifically transfusion and blood transfusion pin that has the safety self-destruct structure, particularly its mechanical connecting structure.
Background technology:
At present, traditional transfusion and blood transfusion pin is by needle stand, needle tubing and flexible pipe constitute, after transfusion finishes, the nurse can pull out transfusion needle for the patient, the needle point of the transfusion needle of extracting is exposed to the outside all the time, be easy to stab the related work personnel in the processing procedure afterwards, and patient's blood is easy to remain in the needle tubing surface, therefore the blood that contains virus can cause unnecessary malpractice, cause the diffusion of all kinds of infectious disease, and some illegal retailers can reclaim those used disposable infusion needles in a large number, use to the patient once more after the repacking, brought great harm for the medical safety of entire society.
So be badly in need of a kind of transfusion and blood transfusion pin that has the safety self-destruct structure of exploitation, make transfusion needle after being used to complete, just can realize forcing disposable safety self-breaking, reduce the incidence rate of malpractice, effectively stop the incident that the transfusion needle secondary uses.
Summary of the invention:
The purpose of this utility model is to provide a kind of transfusion and blood transfusion pin that has the safety self-destruct structure, its in transfusion needle needle stand outer setting the safety self-destruct box, after transfusion is finished, the operator only needs to press pressing piece, just can be with the needle stand post-tensioning, because the size of safety self-destruct box is to calculate well, so whole needle stand and needle tubing all can be drawn in the safety self-destruct box, enter the moment of safety self-destruct box when syringe tip, the slope of flexible tab and needle stand matches, needle stand is firmly stuck in the safety self-destruct box, realize perfect safety self-destruct effect, overcome the shortcoming and defect that exists in the prior art.
To achieve these goals, the technical solution of the utility model is: a kind of transfusion and blood transfusion pin that has the safety self-destruct structure, it mainly comprises needle stand, be provided with needle tubing in the cavity of needle stand one end, the other end of needle stand is socketed with flexible pipe, it is characterized in that: described needle stand outside is provided with the safety self-destruct box, needle stand is set in the safety self-destruct box, described needle stand one side outer wall place is provided with elastic arm, one end of elastic arm is fixed on the needle stand outer wall, the other end of elastic arm props up the step at safety self-destruct box inwall place, step one side is provided with pressing piece, described needle stand opposite side outer wall place is provided with slope wide at the top and narrow at the bottom, and the safety self-destruct box inwall place of this side of slope is provided with flexible tab.
The utility model discloses a kind of transfusion and blood transfusion pin that has the safety self-destruct structure, product adopts needle stand retracting type structure, its characteristics are after the operator extracts transfusion needle, the flicking pressing piece just can pull back needle stand, take advantage of a situation needle tubing is brought in the safety self-destruct box, realize safe effect, enter the moment of safety self-destruct box when syringe tip, the flexible tab at safety self-destruct box inwall place can firmly be blocked needle stand, make needle stand again can't be subjected to displacement forward, cause transfusion needle to be used once more, realize the effect of forced self-destruction, this product integral layout is reasonable, project organization is ingenious, and the most estimable is easy to assembly, has reduced the difficulty of die sinking, effectively reduce the cost of Development and Production, and improved production efficiency, and product job stability height, safety self-destruct is effective, overcome all technical problems that exist in the prior art fully, had outstanding substantive distinguishing features and obvious improvement in terms of existing technologies.
