Description

Position of radial artery checkout gear and method

Technical field

The present invention relates to the artery position detection range.

Background technology

Radial artery injection is an a kind of important medical procedure of importing blood medicinal liquids such as (or) anesthesia to patient.The radial artery puncturing technology also is one of important channel of medical science chemical examination, is usually used in the collection of patient artery blood gas analysis specimen, the blood-letting treatment of polycythemia of newborn, the aspects such as exchange transfusion of hyperbilirubinemia of newborn.

Radial artery is a brachial artery branch, between brachioradialis and pronator ters, descending along forearm oar side companion radial nerve,superficial, going between brachioradialis tendon and flexor carpi radialis muscle tendon above the radiocarpal joint, the artery position table is shallow, radial artery goes to the back of the hand through the processus styloideus radii far-end, wears the first metacarpal bone gap to the dark face of palm, coincide into deep palmar arch with metacarpal artery,volar,deep.At the processus styloideus radii facies palmaris, radial artery branch bank is in different directions, herein radial artery diameter average out to 0.27 (0.22 ~ 0.23) cm.

By the anatomic characteristic of above-mentioned radial artery as can be known, radial artery pulse wider range is difficult for the location.At present, medical personnel mainly determine the position of radial artery by the finger fingertip digital palpation for examination of trauma, and the dependence experience is selected the inserting needle position.Because the finger contact area is big, its sensitivity is not high, thereby causes the inserting needle success rate to reduce, and brings very big misery to the patient.Hospital presses for a kind of intelligent easy measuring instrument that can accurately indicate position of radial artery.
