Description

Upper arm supporting and fixing device for radial artery puncture

Technical Field

The utility model relates to an upper arm supporting and fixing device for radial artery puncture, and belongs to the field of medical appliances.

Background

Coronary atherosclerotic heart disease (coronary heart disease for short) is the most common cardiovascular disease in clinic, and if the coronary atherosclerotic heart disease cannot be effectively treated for a long time, myocardial infarction and even sudden death can be caused. Therefore, the coronary artery (coronary artery for short) is required to be confirmed by coronary artery angiography examination, and when the coronary artery stenosis reaches a certain degree, the coronary artery stent implantation is required to be completed synchronously so as to achieve the purpose of recovering the smooth blood flow of the coronary artery.

At present, the popular way at home and abroad is to use the radial artery puncture approach as the approach of a coronary angiography catheter. The radial artery puncture method is convenient for hemostasis, can obviously reduce the time for a patient to lie in bed after operation and relieve the pain of the patient, and is the first choice of the vascular puncture method for coronary angiography examination and coronary stent implantation. However, during a radial artery puncture procedure, patient coordination is required to abduct the upper arm and maintain that position throughout the interventional procedure. Now, a simple flat plate is usually placed under the cushion of the digital subtraction angiography examining table to help the patient keep the upper arm abducted, but the following defects exist:

critical coronary heart disease patients often have abnormal consciousness state, can not match with radial artery puncture requirements, can not independently place the upper arm on the pressing plate, and keep the upper arm abducted all the time in the intervention process. At present, a method of fixing the upper arm of a patient by a binding belt is generally adopted, but the binding belt and a digital subtraction angiography examination bed are not matched. More importantly, the bound part is often overlapped with the radial artery puncture part on the wrist of the patient, so that the difficulty of the radial artery puncture and intervention process is increased, and the risk of unpredictable medical accidents is caused.
