Description

Technical Field

[0001] The utility model relates to the technical field of arterial puncture stents, in particular to an adjustable arterial puncture stent structure. Background Art

[0002] Continuous intra-arterial pressure monitoring has the advantages of sustainability, dynamism, and timeliness, and is widely used as the gold standard for invasive monitoring in clinics. It is now increasingly widely used in clinics and is suitable for continuous monitoring of arterial blood pressure in perioperative patients, blood gas analysis, and interventional surgery for special examinations or treatments such as angiography and hemodialysis. Critically ill patients need to retain arterial catheters for a long time during the perioperative period due to their condition, which places high demands on the patient's fixed position during the operation of this technology and the retention of the catheter after the operation.

[0003] The radial artery is the first choice for arterial puncture and catheterization. The patient's arm is stretched out 20 to 30 degrees, with the palm facing up and the fingers pointing to the puncturist. A small plastic pillow is placed on the patient's wrist to make the wrist joint in a hyperextension state. The puncture point is 0.5 cm proximal to the radial styloid process, that is, at the second wrist transverse line. The plastic pillow currently used is generally a fixed structure. When in use, it can only produce a fixed hyperextension angle on the patient's wrist. When the patient's wrist angle needs to be changed, the plastic pillow cannot be used for operation. Therefore, we have introduced a new adjustable arterial puncture stent structure. Utility Model Content
