Positioning auxiliary device for peripheral arteriovenous puncture indwelling catheter

Abstract

The invention provides a positioning auxiliary device for a peripheral arteriovenous puncture indwelling catheter. The positioning auxiliary device for the peripheral arteriovenous puncture indwelling catheter comprises a bottom plate, a support and a positioning structure; and the positioning structure is arranged on one side of the support. According to the positioning auxiliary device for the peripheral arteriovenous puncture indwelling catheter provided by the invention, the positioning structure is arranged and can be used in cooperation with the puncture indwelling catheter; the positioning auxiliary device serves as an auxiliary positioning structure of the puncture indwelling catheter; assistance is provided for practice medical staff; the puncture indwelling catheter is effectively positioned when arteries of a patient are punctured; the practice medical personnel only need to push the puncture indwelling catheter to move; the puncture indwelling catheter does not need to be held by hands to move all the time; then, the direct contact area of the hand and the puncture indwelling catheter is greatly reduced; even if the conditions of hand shaking, hand slipping and the like due to tension occur, the influence on the puncture indwelling catheter can be reduced to the minimum; and therefore, the puncture indwelling catheter always moves in a relatively stable state, so that the puncture success rate is greatly improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a positioning auxiliary device for peripheral arteriovenous puncture and catheter placement. Background technique [0002] Peripheral veins refer to superficial veins with relatively fixed anatomical positions on the body surface, mainly located in upper or lower extremities, such as basilic vein, cephalic vein, median cubital vein, great saphenous vein, jugular vein, scalp vein, etc. Arteriovenous puncture catheter is a medical device used to take arterial blood samples. For critically ill patients, the condition is in an unstable state, and there is always the possibility of danger. Therefore, real-time monitoring of blood pressure is required. By using arterial The puncture and catheterization technology can monitor the patient's arterial and venous blood pressure in real time and dynamically, and take blood samples for venous blood gas analysis, and the premise of this technolo...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides a positioning auxiliary device for peripheral arteriovenous puncture and catheterization, which solves the problem that the existing arterial puncture and catheterization operation is relatively difficult to get started, and it is easy to cause hand shaking and hand shaking due to other external factors such as tension. Slippery, weak hands, etc., may lead to operation failure, and it cannot meet the needs of intern medical staff.
