Description

Technical Field

[0001] The invention belongs to the technical field of medical auxiliary equipment, and in particular relates to a radial artery puncture arm support device. Background Art

[0002] Radial artery puncture is a procedure between internal medicine and surgery, and is a new discipline. Radial artery puncture is increasingly used in clinical practice. For patients with hypoxia and respiratory failure, rapid and accurate collection of arterial blood and blood gas analysis can objectively reflect the nature and degree of the patient's respiratory failure, and is a reliable method for clinical judgment of patients' hypoxia and carbon dioxide retention. In monitoring the direct arterial pressure of critically ill patients or patients undergoing large and medium-sized surgeries, extracting arterial blood gas, etc., radial artery puncture and catheterization are required first. In interventional surgery, especially coronary angiography or stent implantation, successful radial artery puncture is the prerequisite for establishing radial artery access and smoothly performing radial artery interventional operations. The first point of radial artery puncture is to expose the radial artery well.

[0003] When radial artery puncture is performed on patients during clinical surgery, the patient's wrist needs to be elevated, the wrist joint is kept in a hyperextended state, and the fingers are in an extended state to keep the skin at the puncture site taut and the radial artery fixed; then use the fingertips to feel the pulsation of the radial artery to be punctured, and the area where the operator feels the pulsation should be reduced as much as possible to narrow the puncture range, which is conducive to improving the success rate of radial artery puncture.

[0004] At present, in actual clinical operation, homemade items are usually placed under the patient's wrist to raise the patient's wrist. This method has the following disadvantages:

[0005] (1) The support angle and height are relatively fixed and cannot be adjusted, so it is not suitable for patients of different ages and body shapes;

[0006] (2) After radial artery puncture surgery, the patient's hand and forearm will swell and hurt. The patient's hand and forearm need to be fixed at a certain angle and height to improve venous return and relieve local pain and swelling. However, the angle and height of the postoperative support pad currently used in clinical practice cannot be adjusted according to the patient's needs;

[0007] (3) Patients may still experience unconscious movements after surgery, and the support pads currently used in clinical practice do not have the function of effectively fixing the hands and forearms.

[0008] Therefore, there is a need for a support device that can adjust the support angle and height, and can fix the hand and forearm, and is suitable for intraoperative and postoperative radial artery puncture surgery. Summary of the invention

[0009] In order to solve the above technical problems, the present invention provides a radial artery puncture arm support device, which includes a base, a support plate, and an adjustment device.

The adjustment device supports the palm support plate, and the angle and height of the forearm support plate and the palm support plate can be adjusted by moving the adjustment device. After the base locks the movement of the adjustment device, the support angle can be fixed; fixing belts are arranged on the upper parts of the forearm support plate and the palm support plate, which can be used to restrain and fix the patient's palm and forearm, and are suitable for use during and after radial artery puncture surgery.
