Description

Technical Field

[0001] The utility model relates to an arterial puncture auxiliary device, and more specifically, to a glove-type inflatable and adjustable radial artery puncture stent. Background Art

[0002] Radial artery catheterization is one of the most common clinical procedures in anesthesiology. The primary purposes of radial artery puncture are to sample blood and monitor arterial pressure. Arterial blood gas testing is an important component of pulmonary function testing. Real-time arterial pressure measurement is widely used during critical, complex, and prolonged surgeries.

[0003] Currently, when performing radial artery puncture and cannulation, the patient's wrist is typically elevated and the palm arched downward to clearly palpate the arterial pulse. Radial artery puncture positioning devices have undergone numerous improvements, including folded cotton yarn, gauze bandages, glass infusion bottles, pillow-shaped gauze mesh, 500ml infusion bags, and gel-based positioning pads. Currently, the most common clinical practice involves folding a sheet into a tube or placing a 500ml infusion bag under the wrist to help elevate the patient's wrist. The puncture site is then elevated at the wrist joint, and the five fingers of the hand are taped together and downwardly fixed to a handrest for puncture and cannulation. However, in practice, this has been found to be inconvenient, ineffective, and resource-wasting, and the tape is required to secure the patient's fingers to the handrest. Its shortcomings are summarized as follows: 1. The wrist is partially suspended in the air when placed, which does not conform to the principle of body placement; 2. The puncture angle between the palm and wrist is different for different patients, and the small pillow is a fixed shape and cannot be adjusted according to the patient's actual angle, thus affecting the success rate; 3. It is easy to contaminate the cloth sheet or the outer bag of the infusion bag. Utility Model Content

[0004] An object of the present invention is to solve at least the above problems and to provide at least the advantages to be described below.

[0005] Another object of the present invention is to provide a glove-type, inflatable, adjustable radial artery puncture stent that is easy to wear and can be operated with one hand. Adjusting the internal pressure of the support air cushion can adjust the angle of the patient's wrist kyphosis to achieve an optimal puncture angle. When not in use, the stent can be folded and attached for easy storage.

[0006] In order to achieve these purposes and other advantages according to the present invention, a glove-type inflatable adjustable radial artery puncture stent is provided, comprising:
