Novel radial artery hemostatic device

Abstract

The invention relates to a novel radial artery hemostatic device. The novel radial artery hemostatic device comprises a hemostatic mechanism and a bandage, wherein the hemostatic mechanism comprises an outer casing; an electronic liquid crystal panel and watch strap rods are arranged on the outer casing; a screw rod penetrates through the outer casing, a retaining disc is fixedly arranged at the upper end of the screw rod, a worm gear is sheathed on the screw rod in a spiral matching way, and is engaged with a worm, and one end of the worm extends out of the outer casing; a strip-shaped key groove is formed in the screw rod, and a key is arranged on the outer casing, and is clamped into the key groove; the lower end of the screw rod is fixedly provided with a connecting shaft; a gasket is fixedly arranged on the connecting shaft, and a silicon rubber casing is sheathed on the gasket; a pressure sensor is arranged in the gasket, and is connected with the electronic liquid crystal panel; the bandage is penetrated and sheathed on the watch strap rods. The novel radial artery hemostatic device has the advantages that the distance of the screw rod can be more accurately adjusted by the worm gear and the worm, and the worm gear and the worm form self-locking; by arranging the pressure sensor in the gasket, the pressure value of pressing on the gasket can be clearly displayed, so as to avoid the injury to subcutaneous tissues by pressing force and the breaking of the connecting shaft.

Description

technical field [0001] The invention relates to the medical equipment industry, in particular to a novel radial artery hemostatic device. Background technique [0002] With the increasing number of patients with cardiovascular disease and the rapid development of interventional medicine, the application of interventional examination or treatment of cardiovascular disease has become more and more extensive. After the treatment or examination is completed, it is necessary to pressurize the puncture point to stop bleeding. There are two types of manual compression and the use of hemostats. Manual compression is labor-intensive, and the pressure is not easy to maintain stable, and it is easy to press the ulnar artery, resulting in bleeding at the puncture point or distal tissue ischemia; some use hemostats, but these Most of the hemostats are only matched with studs and nuts, the self-locking performance is not perfect, and the height adjustment is imprecise. [0003] For examp...

AI Technical Summary

Problems solved by technology

Due to the direct cooperation between the stud and the rotating nut, the device cannot finely adjust the height of the screw

The rubber head of the ball head cannot be rotated, and it is easy to shift, and the device judges the size of the pressure through intuitive observation and is prone to deviation
