Medical anesthetic gas concentration monitoring system

Abstract

The invention discloses a medical anesthetic gas concentration monitoring system. The system comprises a single-chip microcomputer software system and an upper computer test software system. Hardwarecircuits of all parts are controlled by the single-chip microcomputer software system; and the single-chip microcomputer software system also controls a power switch, controls the automatic gain control of a preamplifier, carries out A / D acquisition, performs negative feedback control of an air pump and processes anesthetic gas concentration data. The single-chip microcomputer software is compiledbased on a quasi 32-bit single-chip microcomputer SIC33209 of EPSON. The upper computer test software system mainly realizes waveform display and data post-processing, upper computer software is realized in a VC+ environment, the whole software realizes detection and display of sensor signals, and on the basis, a new software algorithm is developed to identify the type of anesthetic gas and calculate the concentration.

Description

technical field [0001] The invention relates to the field of medical related products, in particular to a medical anesthetic gas concentration monitoring system. Background technique [0002] Monitoring the content of anesthetic gas in the patient's breathing gas during gas anesthesia is of great clinical significance. Anesthesiologists can safely adjust the amount of anesthetic gas input into the patient's body according to the monitoring results, so as to prevent the patient from inhaling anesthetics. Excessive and insufficient lead to life-threatening, anesthesia gas monitoring devices based on the principle of infrared absorption are commonly used clinical instruments. [0003] However, there is a lack of domestic research on this. The anesthetic gas concentration monitoring modules used in domestic medical monitoring products basically rely on foreign imports, which are expensive and limited in promotion. It is urgent to develop a domestic anesthetic gas concentration d...

[0003] However, there is a lack of research on this in China. The anesthetic gas concentration monitoring modules used in domestic medical monitoring products basically rely on foreign imports, which are expensive and limited in promotion. It is urgent to develop a domestic anesthetic gas concentration detection system.
