Automatic radial artery positioning device

Abstract

The invention discloses an automatic radial artery positioning device which is characterized by comprising a fixing device, a movement module, a measurement module and a control module, and the movement module, the measurement module and the control module are arranged on the fixing device and fixed to the radial artery of the wrist through the fixing device. The control module is connected with the movement module and the measurement module, the control module controls the movement module carrying the measurement module to move, and the measurement module collects pressure and jumping amplitude of different positions of the radial artery and transmits the pressure and the jumping amplitude to the control module. The control module judges whether the current position is the optimal position for measuring the radial artery or not according to the pressure and beating amplitude signals collected by the measuring module, and then the optimal position for measuring the radial artery is positioned. The time for a doctor to manually search for the radial artery can be greatly shortened, meanwhile, non-invasive blood pressure detection equipment with the device has wider application, and a good clinical effect is achieved.

Description

technical field [0001] The invention relates to a device for automatically locating a radial artery, which belongs to the technical field of medical instruments. Background technique [0002] As one of the most frequently used monitoring methods in the medical industry, non-invasive blood pressure measurement has been troubled by the problem of inaccurate or continuous detection. The most common non-invasive blood pressure measurement is the cuff method, but this method needs to inflate and deflate the cuff to achieve blood pressure measurement, and it is bound to be unable to achieve continuous measurement, and short-term blood pressure changes are very important in many scenarios of. Therefore, a method for continuously and accurately detecting blood pressure is needed. [0003] In human anatomy, the radial artery originates from the bifurcation of the brachial artery in the antecubital fossa. It extends from the front end of the forearm to the distal end and is the main...
