Arterial-puncture positioning assisting device

Abstract

The invention discloses an arterial-puncture positioning assisting device. The arterial-puncture positioning assisting device comprises a shell and a detecting structure, wherein the detecting structure comprises a positioning rod fixedly connected at the bottom of the shell, a fixing pressing block is slidingly arranged on sliding grooves in the two sides of the positioning rod, limiting assemblies are arranged between the sliding grooves and the fixing pressing block, and a puncture through groove is formed in one long edge of the fixing pressing block; a V-shaped groove is formed in the bottom of the positioning rod, a laser lamp is arranged at the groove bottom of the V-shaped groove, vibrating sensors are arranged at the bottoms of all the side walls of the V-shaped groove, and pulsereminding modules are correspondingly embedded into the groove balls of the V-shaped groove in the corresponding positions of all the vibrating sensors. The arterial-puncture positioning assisting device is simple in structure and convenient and fast in operation, the two vibrating sensors are simultaneously used for detecting arterial pulse signals, when arterial pulse signals with large intensity are detected through the two vibrating sensors, arteries between the two vibrating sensors are puncture parts, projection points between the two vibrating sensors of the laser lamp are striking puncture points, and the arterial positioning success rate is increased.

Description

technical field [0001] The invention relates to medical equipment, in particular to an auxiliary positioning device for arterial puncture. Background technique [0002] Arterial blood pressure monitoring and blood gas analysis are important monitoring means to grasp the condition of critically ill patients in real time, so arterial puncture is usually required clinically for critically ill patients. Before arterial puncture, it is usually necessary to find the location of superficial arteries (such as radial artery, brachial artery, dorsalis pedis artery, femoral artery, etc.), and then puncture the target location. The traditional arterial search method is based on the doctor’s experience by feeling the pulse. Because the artery is often accompanied by the vein of the same name, it is easy to slip, and the blood circulation speed of critically ill patients is slow, and the pulse of the blood vessel is weak. Needle can be inserted in patient's artery only by puncturing, and...

AI Technical Summary

Problems solved by technology

Although the auxiliary positioning pen has improved the speed of arterial search to a certain extent, it only has the function of finding. When puncturing, the positioning pen needs to be picked up and then punctured. Therefore, the positioning pen still cannot overcome the traditional touch search. Fixed technical issues, there are still problems with repeated multiple piercings during the actual piercing process
