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.

Abstract

The invention provides a positioning aid device for peripheral arterial and venous puncture and cannulation. The positioning aid device for peripheral arteriovenous puncture and cannulation comprises: a bottom plate and a support; and a positioning structure, wherein the positioning structure is arranged on one side of the support. The invention provides a positioning aid for peripheral arterial and venous puncture and cannulation. By setting a positioning structure, it can be used in conjunction with puncture and cannula. As an auxiliary positioning structure for puncture and cannula, it provides assistance for medical practitioners. During puncture, the puncture cannula can be effectively positioned. The medical practitioners only need to push the puncture cannula to move, and they do not need to hold the puncture cannula to move all the time, which greatly reduces the direct contact area between the hand and the puncture cannula. In the event of nervousness and tremors, slippage, etc., the impact on the puncture cannula can be minimized, so that the puncture cannula can always move in a relatively stable state, thereby greatly improving the puncture success rate.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a positioning aid device for peripheral arteriovenous puncture and cannulation. Background technique [0002] Peripheral veins refer to superficial veins with relatively fixed anatomical positions on the surface of the body, mainly located in the upper or lower limbs, such as the noble veins, cephalic veins, median cubital veins, saphenous veins, jugular veins, scalp veins, etc. Arterial and venous puncture catheter is a medical tool for taking arterial blood samples. For critically ill patients whose condition is in an unstable state, there is always the possibility of danger, so it is necessary to monitor their blood pressure in real time. 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. In this case, it will increase the difficulty of c...
