Technical Field

[0001] The utility model relates to a fixing device, in particular to a radial artery puncture fixing device. Background Art

[0002] Radial artery puncture is commonly used for puncture and blood sampling during interventional treatment of coronary heart disease and invasive blood pressure monitoring and arterial blood gas analysis in the anesthesiology department. In clinical medicine, the radial artery is thin and difficult to puncture. When performing radial artery puncture, the patient needs to lie flat on the bed with his arms naturally extended and his palms facing up. At this time, a doctor uses manual pressure to fix the patient's arm and hand, and then another doctor performs the puncture operation. At present, there are a large number of patients who need radial artery puncture in the hospital every day. The method of doctors fixing the patient's arm and wrist by manpower requires a lot of physical strength, which will lead to high work intensity for doctors. In addition, when using the above method for radial artery puncture, the hand and arm are in a horizontal state, and the radial artery cannot be clearly exposed, which seriously affects the success rate of radial artery puncture. Utility Model Content
