Description

Technical Field

[0001] The utility model relates to the technical field of radial artery puncture, in particular to a radial artery puncture stand which is easy to operate. Background Art

[0002] Radial artery puncture is commonly used for interventional treatment of coronary heart disease and invasive blood pressure monitoring in the anesthesia department, and blood sampling during arterial blood gas analysis. In the conventional puncture method, the patient's arm is usually placed naturally on the hand support board, and the medical staff holds the needle with the right hand and the index finger of the left hand needs to touch the radial artery pulse, and then the patient's arm is punctured. The conventional puncture method only uses the hand support board as an auxiliary support for the arm. Although radial artery puncture can be achieved, there are shortcomings. If for some bedridden patients, medical staff often bend over and squat when performing radial artery puncture, which tests the physical strength and endurance of medical staff, and the operation is inconvenient. The radial artery is easy to slide during puncture, increasing the risk of repeated punctures or puncture failures. For some patients who can sit for puncture, due to the difference in height of the patients (such as adults or children), it is also very troublesome for patients of different heights to place their arms flat on the table for puncture. Often, a small table needs to be found for children to use, which is also very inconvenient to operate.

[0003] At present, some radial artery puncture auxiliary frames have also appeared in clinical practice, such as the patent name disclosed in the Chinese Patent Library: A radial artery puncture auxiliary frame, patent number: ZL202121790869.2, announcement date: March 22, 2022, the disclosure content mainly includes a frame, an adjustment seat, a support plate and a fixing member; the adjustment seat is arranged on the frame and can move in the up and down direction on the frame, the fixing member is arranged between the adjustment seat and the frame, the fixing member is used to fix the adjustment seat on the frame, and the support plate is connected to the adjustment seat and is arranged horizontally. The auxiliary frame can be adjusted in height according to different usage conditions, which makes the puncture operation more convenient to a certain extent, but it is still not convenient enough. The overall structural design of the auxiliary frame is not ideal. For example, when the patient's arm is placed flat on the pillow, the arterial pulsation at the puncture position of the arm is often not obvious enough, and it is not exposed enough during puncture. Especially for some patients with vascular collapse or luminal stenosis, it is easy to cause puncture difficulties and inconvenience for medical staff to perform radial artery puncture operations.
