Femoral artery compressor and control method of femoral artery compressor

Abstract

The invention discloses a femoral artery compressor and a control method of the femoral artery compressor. The femoral artery compressor comprises a rotary disc, a first motor, an electric cylinder, a compression transverse rod, a second motor, a compression head and a control system. The first motor is used for driving the rotary disc to rotate, the electric cylinder stands on the rotary disc and comprises a piston and a third motor, the compression transverse rod is connected with the piston and is of a stretchable structure, the second motor is used for driving the compression transverse rod to be stretched, the compression head is fixed to the free end of the compression transverse rod, and the control system comprises a camera, a single-chip microcomputer, three motor drivers, an infrared ray transmitter and an infrared ray receiver. The femoral artery compressor and the control method have the advantages that automatic compression on a femoral artery puncture point is achieved, and the proper intensity of compression on a patient is achieved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a femoral artery compressor and a control method thereof. Background technique [0002] In clinical practice, femoral artery puncture is often used to collect arterial blood samples or some special examinations, pressurized blood transfusion in emergency, and used for regional chemotherapy. After the blood transfusion or blood draw is over, the needle should be pulled out quickly. Usually, three to five sterile cotton swabs or gauze should be used locally to press the femoral artery puncture point for more than 15 minutes. After the operation, the patients were scarce and had no strength to press the femoral artery puncture point for a long time. However, if the femoral artery puncture point was not pressed in time, a large amount of blood would flow out of the body, threatening the patient's life.

AI Technical Summary

Problems solved by technology

But this femoral artery compression hemostat also needs others to fix the support base plate on the human body, which is inconvenient to operate, and when adjusting the distance between the compression head and the support base plate, it is only known that the adjustment compression head has touched the femoral artery puncture point, and the pressure is not known. Severity, if the compression is too heavy, the human body will be over-extruded, and the human body will feel uncomfortable; if the compression is too light, the compression force will be insufficient, and blood will overflow at the puncture point of the femoral artery
