Description

Tourniquet for dialysis

Technical Field

The utility model belongs to the field of medical appliances, especially, relate to a hemodialysis is with pressing arteries and veins area.

Background

Hemodialysis is one of the kidney replacement treatment modes of patients with acute and chronic renal failure. The vascular access is a life line for hemodialysis patients to maintain dialysis, and the autologous arteriovenous internal fistula is the preferred vascular access of the patients. The internal arteriovenous fistula is characterized in that an artery of a blood vessel of a limb of a patient at the far end of an arm is anastomosed with an adjacent vein by using an operation method, partial arterial blood of the artery flows into the anastomosed vein, and the vein is arterialized. When each dialysis treatment is finished, the puncture blood vessel of a patient with arteriovenous internal fistula needs to be subjected to compression hemostasis. Aiming at different patients, due to the different sizes of the binding parts, the proper binding is realized, the hemostatic effect can be achieved, the blood vessels are not compressed excessively, and the blood flow is reduced.

At present, ordinary tourniquets are commonly used in China to perform compression hemostasis, gauze is generally placed at a puncture part, then the tourniquets are used for fixing the compression hemostasis, an operator determines the tightness of binding according to the experience of medical staff, whether bleeding exists or not through visual observation and the subjective feeling tightness degree judgment of a patient, the tightness and the applied pressure cannot be quantized, the accuracy is low, the error is large, the degree of grasp is more discounted greatly, meanwhile, the adjustment process is very complicated and time-consuming, and the experience of the patient is very poor; also, there are differences between different operators, resulting in unstable patient comfort. Set up on some tourniquets now and press and detain, replace the gauze to strengthen hemostatic effect, nevertheless it is harder to press and detain relative gauze to stanch, and it is poor to bind for a long time and press the comfort level.
