Description

Automatic radial artery haemostat of decompression

Technical Field

The invention relates to the technical field of medical instruments, in particular to an automatic pressure-reducing radial artery hemostat.

Background

The radial artery is one of the terminal branches of the brachial artery and is slightly smaller than the ulnar artery. 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 downwards and outwards, passes through between the brachioradialis muscle and the circumflex muscle, then is positioned between the flexor carpi radialis and the brachioradialis muscle, and enters the nasopharynx fossa of the 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, passes through the gap of the 1 st metacarpal bone and enters the deep part of the palm, and is divided out of the main artery of the thumb, and then is anastomosed with the deep branch of the ulnar artery to form the deep. The radial artery is shallow between the lower end of the radius and the flexor carpi radialis tendon, and is an ideal site for palpating the pulse and performing a puncture. The radial artery has a constant two-vein tracing. Drawing a straight line from 2.5cm below the center of the antecubital fossa to the inner side of the styloid process of the radius, and taking the straight line as the body surface projection of the radial artery.

Coronary intervention is a non-surgical treatment of minimally invasive coronary heart disease. Coronary intervention (TFI) via the femoral artery approach is gradually replaced by radial artery approach intervention (TRI) due to its postoperative complications such as hematoma at the puncture site, vasovagal reflex, venous thrombosis of the lower extremities, arteriovenous fistula, pseudoaneurysm, etc. TRI is a novel interventional therapy method, has small operative wound, few complications and no need of position limitation after operation, is easier to be accepted by doctors and patients, and needs to stop bleeding in time when secondary bleeding is easy to occur after radial artery operation.

At present, a radial artery compression hemostat is widely adopted when hemostasis is carried out on a radial artery; the self-adhesive hemostatic bandage mainly comprises a spiral handle assembly, a pressing plate, a base and a self-adhesive non-woven bandage, and is used for artery compression hemostasis; when in use, a doctor needs to rotate the spiral handle to release pressure. However, in most cases, due to the fact that doctors are heavy in affairs, it is difficult to perform the rotation pressure releasing operation in a timely manner, so that the pressure cannot be released in a timely manner, hands of patients swell, and the occurrence rate of pressure injury is high.
