Problems solved by technology

It takes an average of 1-1.5 hours to complete a smell test for a patient with anosmia, which is very labor-intensive and increases the chance of misjudgment
In addition, different smelling agents are easy to spread to the surrounding air, which affects the accuracy of the inspection
Blindfolding the subject for a long time can easily cause discomfort and intolerance to the subject

Embodiment 1

[0067] In this embodiment, 10 patients with olfactory impairment and 10 normal sense of smell volunteers were selected to perform manual and automated olfactory tests and scoring systems for standardized smell stick tests, and the results are shown in the following table:

[0068] Anosmia (artificial) Normal sense of smell (artificial) total Olfaction (system) 10 0 10 normal sense of smell (system) 1 9 10 total 11 9 20

[0069]The results show that when using the automated olfactory test and scoring system of the present invention to test, 10 people had olfactory disorders as a result of manual testing and system testing, and 9 people had normal sense of smell as a result of manual testing and system testing. For olfactory disorder and the system test result is 1 person with normal sense of smell, there is no case where the manual test result is normal smell and the system test result is olfactory disorder. Therefore, compared with th...

The system comprises a smell stick box and a control panel, wherein a plurality of smell stick units are arranged in the smell stick box, a test zone is arranged at one end, close to a testee, of the smell stick box, each smell stick unit comprises a shell body, a cover is arranged at one end, close to the testee, of eachshell body, a propeller is arranged at the other end of each shell body, a smell stick is accommodated in each shell body, all smell sticks contain snuffs of different smells, the smell sticks can beexposed to the test zone under the pushing of the propellers, and the control panel is used for controlling operating of the smell stick box and inputting a test result.

Description

technical field [0001] The invention relates to an automatic olfactory test and scoring system and its application, and is especially suitable for population olfactory census and judgment of hyposmia degree of patients with clinical olfactory disorders. Background technique [0002] Smell is the perception of smell, which plays an important role in people's social interaction and daily life. Anosmia can affect people's quality of life, social interaction, nutrient intake, and even threaten life safety. The self-reported prevalence of olfactory disorders ranges from 1.4% to 40.0%, while the prevalence rate of olfactory disorders obtained by olfactory psychophysical tests is 4.7% to 27.0%; the self-reported prevalence of olfactory disorders in China is 2.4%. Data on the prevalence of anosmia on psychophysical tests are lacking. The prevalence rate of self-reported olfactory disorder among residents aged 60 and over in China was 8.49%, and it increased with age. [0003] Olf...
