Abstract

The invention discloses a device and a method for detecting the position of a radial artery, which relate to the field of detecting positions of arteries and solve the problem that the position of the radial artery detected by the existing method for detecting the position of the radial artery is inaccurate. The device comprises an imaging module and a lighting module, wherein the imaging module images an imaging surface of a probe array; the lighting module provides an auxiliary light source for the imaging module; and a signal output end of the imaging module is connected with a signal input end of a signal processing and displaying module. The method comprises the following steps of: closely contacting detection surface of the probe array with a wrist skin; during a set time period, continuously imaging the lateral surface of the probe array; comparing all the acquired images; analyzing discrete points formed by detection ends of all probes in each image; searching the discrete points having the maximum displacement changes; and determining the probes in the probe array, which correspond to the discrete points having the maximum displacement changes, and the position of the wrist skin contacted by the probes is the position of the radial artery. The device and the method are suitable for occasions for detecting the position of the radial artery.

Description

technical field [0001] The invention relates to the field of arterial position detection. Background technique [0002] Radial artery injection is an important medical method to infuse blood (or anesthesia and other medicinal solutions) into patients. The radial artery puncture technique is also one of the important ways of medical testing, which is often used in the collection of samples for arterial blood gas analysis, bloodletting treatment for neonatal polycythemia, and exchange transfusion therapy for neonatal hyperbilirubinemia. [0003] The radial artery is a branch of the brachial artery, between the brachioradialis muscle and the pronator teres, along the radial side of the forearm with the superficial branch of the radial nerve descending, above the radiocarpal joint between the brachioradialis tendon and the flexor carpi radialis tendon, the artery The location is superficial. The radial artery passes through the distal end of the radial styloid process to the ba...
