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.
