Description

Timed deflation type radial artery compression hemostasis instrument

Technical Field

The utility model belongs to the technical field of medical instruments, and particularly relates to a timing deflation type radial artery compression hemostasis instrument.

Background

The radial artery was about 21.2cm long with an outside diameter of about 0.3cm at the beginning. After the brachial artery is divided, the patient goes outward and downward, passes through the brachial radial muscle and the circular pronator, then is positioned between the flexor of the radial wrist and the brachial radial muscle, and enters the nasopharynx fossa for pars plana after the lower end of the radius obliquely passes through the tendon deep surface of the extensor hallucis longus and the extensor hallucis brevis to the back of the hand, enters the deep part of the palm after penetrating the 1 st metacarpal gap, and is anastomosed with the deep branch of the ulnar artery to form the deep arch of the palm after dividing the main artery of the thumb.

Coronary angiography is performed by passing through a radial artery through a specific cardiac catheter, delivering the cardiac vascular access to the root of an aorta through a femoral artery if radial puncture is difficult, inserting a small amount of contrast agent into a left coronary artery port and a right coronary artery port, and observing the stenotic condition and the stenotic part of each coronary artery under continuous radiography. Coronary angiography typically requires compression for 3 hours or more to prevent bleeding clinically. The compression pressure needs to be adjusted in time in the compression stage, so that the problems of hand edema, bluish purple, necrosis and the like of the patient caused by too long compression and too large pressure are prevented while bleeding is prevented. Therefore, it is very important to adjust the pressure at the radial artery compression site in time. Generally, a nursing staff is required to perform pressure reduction operation for several times at regular time, the nursing staff is required to pay attention to the oppressed time point in the process to perform the operation, the time of the nursing staff is greatly occupied, and sometimes the nursing staff is busy in other work and careless, so that related complications are caused. In the daily radial artery, a radial artery puncture mode is often adopted to collect blood samples of patients in the treatment steps of blood sampling inspection, puncture, transfusion and the like. However, in the radial artery puncture procedure, a large number of capillaries are formed between the radial artery and the skin, so that the capillaries are easily punctured, and the capillaries bleed. Because the pressing time is long, bleeding and subcutaneous blood stasis at a puncture point are often caused by improper hemostasis, and swelling and pain of tissues at the blood sampling position also occur occasionally. Many patients can stop bleeding by pressing for effective time after the puncture or some patients are inconvenient to press by themselves, so that the blood vessel can continuously bleed due to short pressing time, and psychological stress and pain are caused to the patients. In addition, the artificial pressing of the needle eye part through the sterilized cotton ball or the sterilized cotton swab to stop bleeding is inconvenient for the patient, and the comfort of the patient is greatly reduced.

The utility model aims at the problems and provides a timed deflation type radial artery compression hemostatic device.
