Intelligent tourniquet device

Abstract

The invention discloses an intelligent tourniquet device which comprises a nylon belt, a thin film pressure sensor, a controller and nickel-titanium alloy wires, wherein a plastic female opening and aplastic male opening are formed in the front end and the rear end of the nylon belt respectively, the nickel-titanium alloy wires are sewn on one surface of silica gel cloth in a parallel uniform arrangement mode, the other surface of the silica gel cloth is attached to the front surface of the nylon belt, the controller is installed on the front surface of the nylon belt, and the thin film pressure sensor is installed on the back surface of the nylon belt; and through holes are formed in the nylon belt at the plastic male opening end at equal intervals, one end of each nickel-titanium alloywire is connected with the controller, and the other end of each nickel-titanium alloy wire penetrates through the two through holes and returns to be connected with the controller.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an intelligent tourniquet device. Background technique [0002] The traditional tourniquet is made of medical polymer material natural rubber or special rubber, which has strong stretchability and achieves the purpose of hemostasis by compressing blood vessels and restricting blood flow movement. It is suitable for medical emergency hemostasis and various surgical operations, and is also suitable for daily life. Emergency hemostasis for middle limb bleeding and wild snake and insect bite bleeding. If the tourniquet can be used correctly during the operation, it can effectively stop the bleeding, ensure that the wound does not ooze, facilitate the operation and effectively shorten the operation time, reduce the chance of infection and reduce the pain of the patient. It is especially important in limb surgery. . [0003] When the traditional tight tourniquet is used, the tourni...

AI Technical Summary

Problems solved by technology

The pneumatic tourniquet is inflated during the operation, and automatically adjusted according to the preset pressure value, continuously inflated and deflated, so as to realize the control of the hemostatic pressure, but the operation of the pneumatic tourniquet is cumbersome during the inflation and deflation process. The control structure is bulky, has high requirements for the control of the inflatable motor, and requires a large power supply. It is difficult to realize strict monitoring and control of pressure, the degree of intelligence and reliability is low, and it is impossible to realize wearable
