Problems solved by technology

In this scheme, only the change and control of different odors can be realized, but due to the lack of quantitative feedback, it is impossible to determine the intensity of the same odor when the patient breathes, so the goal of quantitative analysis cannot be achieved

Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 3 As shown, a quantitative olfactory detection device includes a host computer, a control core module and an olfactory diffusion chamber. The host computer is connected to the control core module through a network port, a USB port or other communication ports, and the host computer and the control core The control command information is bidirectional interactive transmission, and the status information is fed back to the host computer by the control core module one-way. The control core module and the olfactory diffusion chamber are connected by two air paths. The olfactory diffusion chamber mainly performs gas path switching and odor mixing according to the control core control instructions, and feeds back the concentration and pressure of odor molecules to the control core module. .

Abstract

The invention discloses a quantitative olfactory detection device which comprises an upper computer, a control core module and an olfactory diffusion chamber. The upper computer is connected with thecontrol core module by a communication port; the control core module is connected with the olfactory diffusion chamber by a gas path; the control core module comprises a control unit, a main gas pumpand an olfactory gas pump; the control unit is respectively connected with the main gas pump and the olfactory gas pump by a speed controller; a gas outlet of the main gas pump is connected with a main gas path flow sensor by a main gas path, and then is connected to a pressure sensor by a mixed gas path; a gas outlet of the olfactory gas pump is connected with an inlet of an olfactory bottle by astimulation gas path; after being sequentially connected to a stimulation gas path flow sensor and a concentration sensor by gas paths, an outlet of the olfactory gas is connected to the pressure sensor by the mixed gas path; and mixed gas is conveyed to a tested object after passing through the pressure sensor. According to the invention, volume concentration of odor molecules can be accuratelyfed back so as to achieve a quantitative olfactory stimulation function.

Description

technical field [0001] The invention relates to a quantitative smell detection device, which belongs to the field of medical detection. Background technique [0002] According to the survey, the prevalence of allergic rhinitis in China is about 17.6%, that is, about 250 million patients are troubled by allergic rhinitis. During the onset of allergic rhinitis, patients may experience symptoms such as paroxysmal sneezing, clear watery nasal discharge, nasal congestion and nasal itching, and some patients may be accompanied by symptoms of hyposmia. Allergic rhinitis may also cause various diseases including asthma, conjunctivitis, chronic rhinosinusitis, adenoid hypertrophy, and secretory otitis media. Therefore, it is of great social significance to do a good job in the diagnosis of allergic rhinitis. [0003] At present, the conventional diagnostic methods for allergic rhinitis are clinical observation, skin prick allergy test and serum specific IgE detection to comprehensi...
