Pressing hemostasis device used after angiocardiography

Abstract

The device comprises a shell and a rubber bag, the top face of the shell protrudes to form a barrel, the rubber bag is arranged in the shell, the position, right opposite to the barrel, of the rubber bag protrudes to form an extrusion part, the extrusion part is inserted into the barrel, and an adjusting mechanism for adjusting the strength of the rubber bag is installed at the upper end of the barrel. A through hole is formed in the side, located on the cylinder, of the shell, a liquid injection pipe is installed at the position, right opposite to the through hole, of the rubber bag, the upper end of the liquid injection pipe penetrates through the through hole and is provided with a valve, and hemostatic cotton is arranged on the bottom face of the rubber bag. The device is simple in structure, the shell can be rapidly fixed to an arm through the male hook-and-loop fastener and the female hook-and-loop fastener, the pressure acting on a wound can be adjusted through the adjusting mechanism according to the bleeding degree, discomfort caused by too large pressure is avoided; meanwhile, cold water can be injected into the rubber bag, the flowing speed of blood at the wound is reduced in a cold water ice compress mode, and the bleeding amount is reduced.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a pressure hemostasis device after angiography. Background technique [0002] Coronary arteries are blood vessels that supply myocardial blood. There are two branches, left and right, which directly open into the left and right aortic sinuses at the root of the aorta. It is also opaque and overlaps with the heart, so when atherosclerotic plaque or stenosis occurs in the blood vessel cavity, it cannot be seen under ordinary X-rays. Cardiovascular angiography is to use a specially designed cardiac catheter to percutaneously puncture the femoral artery of the lower extremity and go retrograde along the descending aorta to the root of the ascending aorta. Movie camera or tape video, so that the main trunk of the left or right coronary artery and the vascular lumen of its branches can be clearly displayed, and it is possible to know whether there are stenosis lesions in th...

AI Technical Summary

Problems solved by technology

[0003] After the percutaneous puncture of the angiography, the hemostasis of the puncture site is generally adopted when the radial artery is extubated and after the extubation. Although the purpose of hemostasis can be achieved, the medical staff usually press continuously for more than 30 minutes. The labor intensity is very high, which increases the difficulty of work for medical staff
