Radial artery hemostatic device

Abstract

The invention discloses a radial artery hemostatic device which comprises a fixing belt, a fixing plate, a positioning ring, a threaded rod and a compression head. The fixing belt is connected to the two ends of the fixing plate to form a closed ring shape. The positioning ring is located in the center of the fixing plate opposite to the fixing belt. The threaded rod perpendicularly penetrates through the fixing plate through the positioning ring. The compression head is arranged at the portion, at one end of the fixing belt, of the threaded rod. Two movable cloth rings winding around the fixing belt are arranged on the fixing belt. A soft rubber pad is arranged on one face, in the direction of the center surrounded by the fixing belt and the fixing plate, of the movable cloth rings. After the hemostatic device is improved, unblocked venous return can be effectively supported and ensured, artery punctures can be effectively compressed, arm circulation is not affected, extravasated blood, errhysis, edema, swelling and bleeding are effectively reduced, and a patient does not have the feeling of numbness after an operation.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a radial artery hemostat, which can help patients to stop bleeding after radial artery puncture and interventional operation. Background technique [0002] In today's society, coronary heart disease has become the first killer of human beings, and percutaneous transluminal coronary angioplasty (PTCA) has been called one of the main means of coronary heart disease treatment. There are two kinds of puncture approaches: femoral artery and radial artery. Femoral artery puncture has many inconveniences and disadvantages; radial artery puncture is better. After coronary angiography and stent implantation, patients need to take anti-platelet aggregation drugs (Plavix, Aspirin), anticoagulant drugs (heparin), etc. These drugs can affect the patient's blood coagulation function, prolong the bleeding time, and easily cause puncture. The site is bleeding. After the abo...

Problems solved by technology

However, while the device compresses the radial artery, it also obstructs the venous return of the patient's distal arm, resulting in edema, congestion, bleeding, and swelling of the distal arm at the puncture site, as well as scattered bleeding points caused by capillary rupture, causing serious damage to the patient. pain, and affected the patient's life and postoperative observation

Increase the number of days of hospitalization of patients, that is, increase the cost of hospitalization
