Arteriopuncture catheterization auxiliary device

Abstract

Disclosed is an arteriopuncture catheterization auxiliary device comprising a pressurized inflation rubber ball, the air outlet end of the pressurized inflation rubber ball fixedly communicates with a first air inlet pipe, a second air inlet pipe and a third air inlet pipe, one end of the first air inlet pipe fixedly communicates with an annular arm ring, and one end of the second air inlet pipe fixedly communicates a wrist pressurized air cushion. two sides at the top end of the wrist pressurized air cushion are fixedly equipped with fixing parts. Arms of a patient can be rapidly fixed, the wrist pressurization air cushion is rapidly inflated through the pressurization inflation rubber ball so that the back of the palm can be bent to a certain angle, then the ulnar artery and the radial artery can be fully exposed, clinical operation is facilitated. The invention is convenient and economical to use, capable of fully exposing the ulnar artery and the radial artery to assist the Allen experiment, capable of rapidly deflating, safe and reliable, the inflation amount of the wrist pressurizing air cushion can be adjusted according to the arm circumference, and the invention is suitable for wider crowds.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an auxiliary device for arterial puncture and catheterization. Background technique [0002] In clinical anesthesia monitoring and critical illness rescue, it is necessary to closely monitor the patient's blood pressure changes, and even to repeatedly take arterial blood samples for blood gas analysis and electrolyte measurement during the operation, to control the patient's vital signs, and to implement some special examinations and treatments (selective arterial And ventriculography, intra-arterial injection of chemotherapy drugs). Invasive arterial puncture catheter pressure measurement (IABP) is a very important monitoring method in clinical work. It can directly and objectively reflect the changes of arterial systolic pressure and diastolic pressure, and provide objective information for modern clinicians to diagnose diseases and judge disease transitions. The digital basis i...
