a tourniquet

Abstract

Provided is a tourniquet matched with a PICC for use. When operations of the PICC are conducted, an operator can directly and timely control contraction and looseness of the tourniquet through indications of a contraction indicator light and a looseness indicator light which have different colors of the indication or one indicator light, assistance of an assistant is not needed, the manpower consumption is reduced, and meanwhile the situation that a sterile area is polluted due to the fact that the assistant ties or loosens an occluding cuff is avoided. In addition, due to the fact that the tourniquet is loosened in time, a ward is polluted due to spill of blood of a patient is avoided. The tourniquet matched with the PICC for use is convenient to use and easy to operate, the outer layer of the tourniquet can be disinfected by being scrubbed through ethyl alcohol, therefore, the tourniquet can be reused, and the cost is low.

Description

technical field [0001] The invention relates to a medical auxiliary tool, in particular to a tourniquet used in conjunction with a PICC. Background technique [0002] PICC is a kind of catheter inserted into the central vein through peripheral venous puncture, punctured by peripheral veins (basilic vein, median cubital vein, and cephalic vein), and the tip is positioned in the superior vena cava or subclavian vein. It can provide patients with medium and long-term intravenous infusion and chemotherapy drugs, reduce the pain of repeated puncture, reduce the stimulation of drugs on blood vessels, simplify the process of central vein puncture, reduce the risk of central vein puncture and infection probability, and prolong the service life of the catheter. residence time. Because of its advantages of convenient operation, safety and reliability, simple maintenance, and long-term indwelling, it has been widely used in clinical practice. [0003] However, during the operation of...

Problems solved by technology

This not only makes the operation cumbersome and increases manpower consumption, but also easily destroys the sterile field and increases the risk of infection for patients; in addition, if the assistant does not release the cuff in time, it will easily lead to blood spillage of the patient, causing inconvenience in operation and contamination of the ward

[0004] In the prior art, there are automatic tourniquets that are not purely aimed at PICCs, which can realize the automation of venous tourniquets, but there are also some defects, such as existing tourniquet devices, including housings, rubber hoses, runners, motors, sensors, and control units. system, etc., the hose is fixed on two wheels, and there is also a collection point indicator light set outside the tourniquet shell, so that the operator cannot control the contraction or release of the tourniquet in time, and the overall tourniquet Large size, inconvenient to operate
