All-around early-warning protective frame for internal fistula puncture bleeding

Abstract

The invention discloses an all-around early-warning protective frame for internal fistula puncture bleeding. The structure is ingenious, and functions are powerful. Firstly, through action of the protective frame, all-around supporting and protecting action on an internal fistula puncture portion of a patient can be achieved; secondly, through cooperative action of liquid detection and a warning mechanism, not only can bleeding detection and warning for the internal fistula puncture portion of the patient be achieved, but also bleeding detection and warning for loose connection of a joint of an internal fistula puncture needle and a joint of a central venous indwelling catheter can be achieved, so that it is convenient to protect the puncture portion of the patient from pressing of quilt strips, and observation is convenient; meanwhile, a medical worker finds bleeding of the patient and conducts emergency treatment on the patient in time, so that complications of the patient are avoided; finally, in the way, not only is safety of the patient improved, but also the burden of the medical worker is reduced, and accordingly clinical application and popularization are promoted.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an all-round internal fistula puncture bleeding warning protection frame. Background technique [0002] As we all know, arteriovenous fistula is the lifeline for maintaining dialysis patients, and good vascular access is an important guarantee for improving the survival rate and quality of life of dialysis patients. Currently clinical hemodialysis patients are prone to mistakenly press the arteriovenous fistula, hemodialysis tubing and fistula puncture needle during sleep, resulting in blockage of blood flow in the fistula, insufficient dialysis blood flow, bleeding, and blockage of the internal fistula; or the patient is restless, Failure to cooperate with the treatment will cause bleeding at the puncture site of the internal fistula or at the site of the venous catheter, which not only brings great safety hazards to the patient's treatment, but also requires re-ostomy, ...

AI Technical Summary

Problems solved by technology

Currently clinical hemodialysis patients are prone to mistakenly press the arteriovenous fistula, hemodialysis tubing and fistula puncture needle during sleep, resulting in blockage of blood flow in the fistula, insufficient dialysis blood flow, bleeding, and blockage of the internal fistula; or the patient is restless, Failure to cooperate with the treatment will cause bleeding at the puncture site of the internal fistula or at the site of the venous catheter, which not only brings great safety hazards to the patient's treatment, but also requires re-ostomy, which not only increases the pain of the patient but also increases the economic cost of the patient. Burden, not conducive to clinical promotion and application

[0003] According to the above, the internal fistula puncture protection device in the current clinical prior art generally has simple structure and single function, such as Chinese patent / CN2014206048419 (hemodialysis internal fistula protection stent), although it has the function of partially protecting the patient's internal fistula puncture site , but the bleeding alarm at the puncture site of the internal fistula cannot be realized, which leads to the inability of the medical staff to deal with the bleeding site of the patient in time, increases the hidden danger of treatment, and easily causes disputes between doctors and patients. In view of the above defects, it is necessary to design an all-round internal fistula Puncture bleeding warning protection frame
