Description
Technical field
This utility model relates to a kind of integration Anti-stabbing hemodialysis puncture needle, belongs to medical instruments field.
Background technology
Hemodialysis is the treatment means of Maintenance Hemodialysis Patients, and sound affectionately internal fistula is the conventional vascular access of dialysis patient.Human body is connected by puncture needle and dialysis pipeline when hemodialysis.
Existing hemodialysis puncture needle includes hollow tube, plastic union pipe, the pin wing, syringe needle, needle cap.Clinically after hemodialysis terminates, generally pin internal fistula hemostasis by compression on the other hand, extract puncture needle on the other hand, then puncture needle is positioned over home, after patient's internal fistula wrapping has processed, being abandoned in the lump in sharp instrument box by puncture needle, this process generally there are following problem: how puncture needle is placed safely after pulling up；Two open ends of puncture needle easily have blood to throw away, and it is that infection risk increases that some patient suffers from infectious disease, medical worker or workman at cleaning environment；Nurse loses back at hand-held puncture needle and causes what patient or medical worker stabbed to have a big risk in the process of sharp instrument box；Medical worker or workman easily stab when clearing up sharp instrument box.
The medical product having official seal pricking wound used clinically is separate configurations separately, and cost improves, and operation easier is bigger.CN201420241896.8 discloses a kind of hemodialysis puncture needle component, is wounded by stabbing infection although it can be prevented effectively from health care workers to a certain extent, but there is baroque defect.
How to design one to be easy to medical worker's one hand and independently operate, effectively stop that medical personnel are needled wound, the risk infected and science, medical product conveniently, safely are those skilled in the art's problem demanding prompt solutions.
Utility model content
The purpose of this utility model is in that to overcome the defect of prior art, it is provided that a kind of reasonable in design, and simple in construction is easy to use, the integrated Anti-stabbing hemodialysis puncture needle that safety is high.
To achieve these goals, the technical scheme that this utility model is taked is as follows:
A kind of integration Anti-stabbing hemodialysis puncture needle, it includes hollow tube, syringe needle, connect the connecting tube of described syringe needle and hollow tube, it is placed on the connection pipe box on described connecting tube outer circumference surface, it is arranged at the pin wing that described connecting tube puts and for protecting the exterior ring cap of syringe needle, described exterior ring cap generally groove-like structure, the rear and front end of described exterior ring cap is respectively arranged with outer shroud running-on, described exterior ring cap is internally provided with interior collar, the front end of described exterior ring cap or rear end are connected with the described pipe box that is connected by contiguous block, the outer circumference surface of the front end of described connection pipe box is fixedly installed the annular dop 8 for locking described interior collar, described exterior ring cap can stir along described contiguous block.
Further improving as this utility model, the opening of described hollow tube is provided with plug, and described plug is connected with described hollow tube by connection strap.
Further improve as this utility model, described hollow tube is equipped with flow-stopping clip.
Compared with prior art, having the beneficial effect that acquired by this utility model:
The exterior ring cap of integration Anti-stabbing hemodialysis puncture needle provided by the utility model can overturn, after upset, the direct retaining ring of exterior ring cap is connecting the outside of pipe box and syringe needle, it is to avoid syringe needle is exposed, effectively reduces medical personnel's risk by needle sting and infection.
This utility model is provided with plug in hollow tube rear end, it is to avoid the blood of hollow tube rear end flows out, and has effectively blocked the propagation of blood born diseases.
This utility model overall structure is simple, and design science is reasonable, and exterior ring cap just can be overturn by medical personnel's one hand, is effectively increased work efficiency, and ensure that the safety and sanitation of operation.
