Odor conduction smell test instrument and control method thereof

Abstract

The invention discloses an odor conduction smell test instrument and a control method thereof. The odor conduction smell test instrument adopts the structure that the input interface of a main controller is connected with an experimental subject, and the output interface is connected with medical equipment; the main controller is electrically connected with allocation controllers; a gas source is connected with two flow controllers through a purifier and a filter, wherein the first flow controller enters an odor transmission pipeline through a humidifier, and the second flow controller is connected with the allocation controllers respectively; the allocation controllers are connected with odor sources respectively; the odor sources are connected with the odor transmission pipeline; the odor transmission pipeline is connected with the experimental subject through a transmission guide pipe; and a power supply supplies power for the test instrument. The odor conduction smell test instrument has the benefits that the odor sources can be directly conveyed into the medical equipment where the experimental subject is placed and is released in a manner of being matched with the breathing of a human body, so that an accurate reflection image of the brain of a human body can be obtained. The instrument has the advantages of simple structure, high integration level, complete functions, low cost, high efficiency, high safety and reliability, long service life and simplicity and convenience in operation.

Description

technical field [0001] The invention relates to a tester; in particular, to an odor conduction olfactory tester and a control method thereof. Background technique [0002] There are many instruments and equipment for the detection, research and analysis of physiological changes in brain functional areas, such as nuclear magnetic resonance, electroencephalography, nuclear medicine functional imaging and other equipment, which provide valuable clinical information for the diagnosis and treatment of human diseases; At present, scientists at home and abroad have widely studied the physiological changes in the brain functional areas of humans and animals after they are stimulated by external odors; especially after different odors are reflected to the corresponding olfactory functional areas of the brain, according to different reflection areas, it is possible to Many diseases can be effectively judged, but because people's sense of smell stays in the brain for only about 6 secon...

[0002] There are many instruments and equipment for the detection, research and analysis of physiological changes in brain functional areas, such as nuclear magnetic resonance, electroencephalography, nuclear medicine functional imaging and other equipment, which provide valuable clinical information for the diagnosis and treatment of human diseases; At present, scientists at home and abroad have widely studied the physiological changes in the brain functional areas of humans and animals after they are stimulated by external odors; especially after different odors are reflected to the corresponding olfactory functional areas of the brain, according to different reflection areas, it is possible to Many diseases can be effectively judged, but because people's sense of smell stays in the brain for only about 6 seconds, without the effective help of accurate auxiliary testing equipment, the brain signals generated by the sense of smell are difficult to be detected by the current MRI, brain Electrograms, functional imaging of nuclear medicine and other equipment can capture them regularly and quantitatively. Therefore, at present, symptom diagnosis can only be made through memory tests, genetic tests, and brain scans. However, medical experts believe that odor discrimination tests are still the most effective method. one
