Background

At present, radial puncture is a common treatment mode, and after a radial catheter is pulled out, a wound needs to be pressed to stop bleeding. The existing radial artery hemostasis methods include an artificial pressing method, a gauze pressurization bundling method and a compressor hemostasis method, and all can play a role in hemostasis. The manual pressing method comprises the following steps: the clinical medical staff continuously presses the radial artery for 15-20 min to stop bleeding. However, this method often causes the hand of the user to be stiff, and if the user presses the hand halfway, complications such as hematoma and limb ischemia may occur due to the difference in the pressing position and the pressure applied. A compression hemostat: hemostasis is compressed by screwing. The hemostat is fixed by a fixing band, and is loosened frequently in use to influence the hemostasis effect. Pressurizing and bandaging with gauze: namely, the pressure is increased by winding multiple layers of gauze, and the method is mostly used clinically at present. However, the tightness of the wrapping method is difficult to control, and hand swelling, numbness, bleeding of puncture parts and the like are often caused; in addition, the dressing area is too large, so that the bleeding condition of the puncture part is difficult to observe; finally, when the pressure of the patient is relieved, the patient is difficult to master the specific pressure by the feeling of medical staff, and the patient may be too loose, so that the puncture part bleeds again. Some instruments for radial artery hemostasis appear in the existing market, some compress hemostasis with gasbag, water pocket, spiral etc. make the operator can't observe bleeding point position and use back hemostasis effect because of its opaque invisible state when using, still bleed, and lead to causing patient secondary injury to the local pressure is too big.
