Combined protection device for hemodialysis

Abstract

The invention relates to the technical field of medical devices, and specifically discloses a combined protective device for hemodialysis, which includes an arm resting base, an arm shield, and a bed body clamping mechanism, and one side of the arm resting base and the arm shield is rotationally connected by a hinge , the front end of the arm shield is provided with two straps, and a fixing device is arranged between the straps and the front side of the base where the arm is placed; the present invention uses the connection mode between the movable rod and the vertical slider and the horizontal slider, The base for placing the arm can be cushioned to a certain extent; the fixing device is a buckle at the lower end of the strap and a buckle sleeve arranged on the front side of the base for placing the arm. When the patient's arm is fixed for hemodialysis, the angle position of the arm can be adjusted according to the actual situation, which can prevent the paralysis caused by the long-term fixed arm, and because of the clamping effect between the arm base and the arm shield, it will not It affects the clamping effect on the arm and can effectively protect the arteriovenous internal fistula.

Description

Technical field [0001] The present invention relates to the technical field of hemodialysis, specifically discloses a combined protection device for hemodialysis. Background technique [0002] Hemodialysis is acute or chronic renal failure patients with renal replacement therapy one way. It does this by draining the blood out of the body, through a dialyzer of hollow fibers consisting of numerous root, like the body containing the blood concentration of the electrolyte solution (dialysate) inside and outside the hollow fibers in a root, by diffusion, ultrafiltration, adsorption and convection principle of material exchange, gets rid of metabolic waste, maintain electrolyte and acid-base balance; at the same time to remove excess water in the body, and through the entire process of purifying blood transfusion is called hemodialysis. [0003] During hemodialysis patients, which is a prerequisite for establishing vascular access its implementation, for each time a hemodialysis treat...

Problems solved by technology

[0003] In the process of hemodialysis, the establishment of vascular access is the prerequisite for its implementation. During each hemodialysis treatment, the patient's dialysis time is as long as 4 hours or more. During the dialysis process, it is easy for the patient to fall asleep, sit up or do other involuntary activities. Causes needles to be removed and blood vessels to be punctured, which brings pain to patients and increases the work difficulty of medical staff

At the same time, the commonly used part of hemodialysis is generally the arteriovenous fistula of the upper limbs. If the patient's arm is not protected by a good protective device, when the patient's arm is pressed by a quilt or touched by other foreign objects, the corresponding fistula may be touched. The corresponding internal fistula puncture needle may puncture the patient's arteriovenous blood vessels and cause subcutaneous hematoma, which will bring pain to the patient.

[0004] The utility model with the patent number CN208525522U discloses a combined protective device for hemodialysis, including a base, a rotating shaft, a cam, a gear sleeve, a gear, a baffle, a spring, a supporting plate, an auxiliary rotating plate, a guide sleeve, and an arc-shaped sliding bar , jacks, bolts, positioning hooks, protective covers, fixing rings, and slings; although the combined protective device for hemodialysis can fix the arm during hemodialysis and protect the arteriovenous fistula, there is little dust in the fixing process. Immobility, long-term fixation may easily cause arm paralysis, which is not conducive to hemodialysis. In addition, the connection between the device and the bed is inconvenient, and it is easy to move, causing the whole device to fall off
