Novel radial artery hemostat

Abstract

The invention relates to a novel radial artery hemostat which comprises a hemostatic mechanism and a bandage, wherein the hemostatic mechanism comprises an outer frame, an electronic liquid crystal panel is mounted at the upper end of the outer frame, a screw rod penetrates through the outer frame, threads on the screw rod are set into threads I and threads II, and the rotating directions of the threads I and the threads II are opposite, a spirally-matched sliding block is arranged on each thread, and a guide rod is fixedly mounted on the sliding block, is clamped in a groove formed in the outer frame and can slide in the groove; a connecting rod is movably connected to the guide rod and is movably connected with a supporting block, a pressure sensor is arranged in the supporting block, a silicon rubber shell is mounted on the supporting block in a sleeving manner, and the pressure sensor is connected with the electronic liquid crystal panel; a through hole is formed in each of the two sides of a frame, and the bandage is tied on the through hole. As a connecting rod mechanism of the novel radial artery hemostat has a telescopic function, the novel radial artery hemostat is compact in design, does not need to occupy a large space and is comfortable in wearing. As the electronic liquid crystal panel covers the upper end surface of the outer frame, a pressure value can be clearly displayed, so that the harm to patients and the damage to the novel radial artery hemostat caused by overpressure are prevented.

Description

technical field [0001] The invention relates to the medical equipment industry, in particular to a novel radial artery hemostat. Background technique [0002] With the increasing number of cardiovascular diseases and the rapid development of interventional medicine, the application of interventional examination and treatment of cardiovascular diseases is becoming 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 kinds of manual pressing and using a hemostat. Manual pressing is labor-intensive, and the pressing force is not easy to maintain stability. It is also easy to press the ulnar artery, causing bleeding at the puncture point or remote tissue ischemia; Most of the hemostats only use studs and nuts, the self-locking performance is not very perfect, and the height adjustment is not accurate. [0003] For example, the authorized notification number is CN202589600 U Chi...

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
