Description

Distal end radial artery compression hemostat

Technical Field

The utility model belongs to the field of medical equipment, concretely relates to is applied to coronary heart disease patient through distal end radial artery intervention postoperative, carries out interim hemostasis by compression device to distal end radial artery puncture position.

Background

At present, the incidence of coronary heart disease is increasing year by year, seriously threatening human health. In the aspect of coronary heart disease treatment, Percutaneous Coronary Intervention (PCI) has quick response and high success rate, and has become a main means for treating coronary heart disease. The PCI puncture access is mainly realized by a radial artery puncture mode, and is specifically divided into a conventional radial artery puncture mode and a distal radial artery puncture mode. The conventional radial artery puncture point is located at the position of the proximal 1cm radial artery pulse of the inner side of the right radial styloid process. The radial artery is adjacent to the radial nerve and is surrounded by the carpal tunnel, and partial patients feel distending pain and discomfort in the wrist and even the forearm after receiving the conventional radial artery puncture intervention, and serious patients can cause irreversible damage to the hand function. In addition, when the right side conventional radial artery fails to puncture (spasm or hematoma), or the bilateral radial artery needs to be punctured due to a special lesion (coronary bypass or chronic occluded blood vessel), the left side radial artery needs to be punctured. When conventional left side radial artery puncture, the patient often feels uncomfortable because the hand needs to keep the outward turning posture for a long time, and the operation degree of difficulty also can increase because of the art person needs to operate on patient's right side simultaneously. In view of this, a distal radial puncture should be made. The far-end radial artery puncture point is positioned on the left extensor hallucis longus tendon, the extensor hallucis brevis tendon and an extensor support band to form a concavity, namely a snuff bottle area, the radial artery at the position is used for supplying blood to both sides and is roughly fixed, the pulsation is not easy to disappear, and the puncture success rate is higher. In addition, the hand of the patient is in a comfortable position in the PCI process, long-time operation can be endured, and the operation of an operator is more convenient. Thus, distal radial artery puncture is becoming more and more popular. The main complications of the distal radial artery puncture are hemorrhage and hematoma, so the compression hemostasis of the puncture point is particularly important. At present distal end radial artery puncture hemostasis by compression adopts gauze bandage or conventional radial artery to press the puncture compressor and oppress, but the gauze bandage dynamics of oppressing is limited to snuff bottle district has certain gradient, and is difficult for fixing, and conventional radial artery puncture hemostasis by compression ware slips easily, thereby causes distal end radial artery puncture point to take place when bleeding, consequently the effectual distal end radial artery hemostasis by compression ware of research and development is imperative.

The three elastic belts wind and fix the compressor on the wrist part according to different directions.

Distal end radial artery hemostasis by compression ware include following beneficial effect:

(1) the spiral compression mode is adopted, the compression force is obviously enhanced compared with the compression of a common gauze bandage, and the hemostatic effect is reliable;

(2) the three elastic belts fix the pressurizing device from three directions, so that the stability of the compressor is obviously improved while the compression effect is enhanced, and the compressor is not easy to slip;

(3) the compressor does not obviously limit the movement of fingers and wrists, has good comfort for patients, does not completely block the blood flow of the wrists, does not influence the venous return of the hands, and does not cause the swelling and pain of the hands.
