Problems solved by technology

The structural principle of the semiconductor strain gauge pressure sensor is that the semiconductor strain gauge or bridge should be pasted on the elastic metal beam, the volume and shape are greatly restricted, and the cost is high and the life is short (easy to break).
Infrared transmissive (finger pulse) sensors have large blood flow waveform distortion due to too many arteriovenous capillaries at the end of the limbs (blood flow phase superimposition and overlap), and the non-standard waveform is not suitable for blood flow parameter analysis, and the relatively narrow range of use

Abstract

The invention discloses a reflective infrared arteriogram collector and sensor, belonging to a field of medical apparatus. The reflective infrared arteriogram collector comprises a shell with a detecting window, a circuit board, an infrared transmitting tube, an infrared receiving tube and a resistance. The infrared transmitting tube and the infrared receiving tube are arranged at the same side of the circuit board. The infrared transmitting tube and / or the infrared receiving tube are connected with a resistance. The invention has the advantages of low production cost, that the infrared reflex sensor for artery and blood stream can accurately collect the blood blow waves of a plurality of parts of a human body like a digital artery, a radial artery, a cerebral artery, a temple and even a palm and a lip part and has an extremely wide application, is a major human evangel for controlling and quickly diagnosing the human cardiocerebriovascular diseases.

Description

technical field [0001] The invention relates to a reflective infrared arterial waveform collector and sensor, belonging to the field of medical instruments. Background technique [0002] Traditional non-invasive blood flow parameter collectors mostly use semiconductor strain gauge pressure sensors to extract radial artery blood flow information. The structural principle of the semiconductor strain gauge pressure sensor is that the semiconductor strain gauge or the bridge is pasted on the elastic metal beam, the volume shape is greatly restricted, and the cost is high and the life is short (easy to break). Infrared transmission (finger pulse) sensors have large blood flow waveform distortion due to excessive transmission of arteriovenous capillaries at the extremity extremities (superposition and overlap of blood flow phases), and non-standard waveforms are not suitable for blood flow parameter analysis, and their relatively narrow use range.
