Abstract

The invention discloses a medical electronic nose gas concentrating system, and a method. The medical electronic nose gas concentrating system comprises a flow rate control unit, a temperature control unit, and an adsorption tube containing a mixed adsorbent. The mixed adsorbent is selected from CarbopackTMB and Tenax GR based on the adsorption capacity of gases; OD1 / 4inch, 7inch Length standard adsorption tube is adopted; and the adsorption tube contains the mixed adsorbent with a thickness ranging from 120 to 150mm; and a first grade Peltier cooling system is adopted by the mixed adsorbent. A gas concentration system is adopted by the medical electronic nose gas concentrating system, so that the detection capacity and capacity of resisting disturbance of the medical electronic nose with the gas concentrating system are both improved, a problem of the prior art that electronic noses can not be directly applied to respiratory gas disease diagnosis because of poor gas sensor detectability is solved, development of olfactory analogue technology of the state is promoted, the gap between the prior art and international advanced level is narrowed, disease early diagnosis is realized, and great practical significance is achieved.

Description

technical field [0001] The invention belongs to the technical field of electronic noses, in particular to a medical electronic nose gas concentration system and method. Background technique [0002] Smell is a physiological response of the biological olfactory system to molecules of a certain gas or volatile substance. The weak signals generated by the olfactory cells in response to the stimulation of odor molecules are transmitted through the olfactory nerve to the olfactory glomeruli, mitral cells, granular cell layer, and finally to the brain center. The biological olfactory system is the biological basis of the artificial olfactory system. Imitating the olfactory system of humans and mammals, the artificial olfactory system (electronic nose) consists of the following parts: sensor array, signal preprocessing, pattern recognition algorithm, and gas collection device and corresponding interface circuit. Functionally, the gas sensor array is equivalent to the olfactory se...
