Tourniquet used for hemodialysis patients and capable of monitoring pressure and errhysis

Abstract

The invention discloses a tourniquet used for hemodialysis patients and capable of monitoring pressure and errhysis and relates to the technical field of medical equipment. The tourniquet comprises adial, wherein a pressure display is clamped on the front side of the dial, an errhysis alarm is clamped on the front side of the dial, a sound damping button is arranged on the upper surface of the dial, a pressure detector is clamped on the back side of the dial, two blood leaking induction pieces are clamped on the back side of the dial, and the pressure detector is located between the two bloodleaking induction pieces. According to the tourniquet used for hemodialysis patients and capable of monitoring pressure and errhysis, under the joint action of the pressure detector, the blood leaking induction pieces, a processor, the errhysis alarm and the pressure display, an operator can clearly know the pressure condition of artery and vein puncture parts, operation of the operator is facilitated, the errhysis condition is reduced, and the operator can further know whether the errhysis condition occurs at artery and vein puncture parts of internal fistula conveniently under the action ofthe blood leaking induction pieces.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a cuff that can monitor pressure and blood seepage for hemodialysis patients. Background technique [0002] Arteriovenous fistulas are the most commonly used long-term vascular access for patients with maintenance hematopoiesis and the most important lifeline for dialysis patients. After the end of dialysis, the arterial and venous ends of the internal fistula are often pressurized and hemostasis is performed clinically. The traditional tourniquet is sewn with a loose elastic band and snap buttons, and is easy to operate. However, due to the subjective assessment and the differences in the patient's vascular conditions, the operator cannot objectively understand the pressure of the blood vessel when hemostasis is applied, resulting in differences in the pressure acting on the puncture site, which often causes bleeding due to too little pressure. Excessive pressure lea...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a cuff that can monitor pressure and blood seepage for hemodialysis patients, which solves the problem that the existing cuff is not highly intelligent and cannot provide operators with Objective pressure values ​​can easily lead to leakage of blood due to too low pressure and blockage of pressure internal fistula due to excessive pressure, which increases the pain and burden of patients, and cannot monitor bleeding and alarm, thus failing to reduce the risk of use by patients
