Inflatable fixing bracket for hemodialysis catheter of nephrology department

Abstract

The invention discloses an inflatable fixing bracket for a hemodialysis catheter of nephrology department, comprising a fixing plate, an air pump is fixedly connected to the right side of the bottom of the inner cavity of the fixing plate, an air inlet pipe of the air pump penetrates the fixing plate and extends to the outside of the fixing plate, and an air outlet pipe of the air pump is communicated with a connecting pipe. The air pump, C-type airbag, the second inflatable tube and the inflatable cushion are arranged, the fixation effect of the arm of the patient is achieved, through the fixture. Threaded holes, lifting plates, threaded shank and fixing block are arranged, the invention achieves the effect that the device is convenient for medical personnel to fix the device on the bed board. As a result, the problem that the sleeping, sitting up and involuntary movement of the patient during the dialysis process can easily lead to the falling off of the dialysis tube, the needle iseasily displaced to cause the phenomenon of puncturing blood vessels, and the normal hemodialysis is affected, which not only causes pain to the patient, but also may cause other unpredictable results, and at the same time, increases the working difficulty of the medical personnel.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an inflatable fixing bracket for a hemodialysis catheter in the department of nephrology. Background technique [0002] Hemodialysis is the most effective treatment for patients with chronic renal failure and acute drug poisoning. At present, clinically, the needles are mainly punctured in the patient's upper limbs. During use, the patient is fixed in a semi-recumbent position and cannot change the position at will. The patient's dialysis time is more than four hours. During the dialysis process, the patient sleeps, sits up and involuntarily All activities are likely to cause the dialysis tube to fall off, the needle is easy to shift and cause blood vessel puncture, which affects the normal hemodialysis, not only causing pain to the patient, but also may cause other unpredictable results, and increase the difficulty of work for the medical staff.
