KIT FOR TESTING OLFACTORY ABILITY AND METHOD FOR TESTING OLFACTORY ABILITY USING SAME Russian patent published in 2025 - IPC A61B5/381 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment, specifically to a kit for testing olfactory ability and a method for testing olfactory ability using same. Kit consists of two bearing panels with 45 glass bottles with caps, containing brushes for substance application on disposable paper blotters, disposable paper blotters and application instruction. First bearing panel contains 25 consecutively numbered glass bottles with n-butanol with increasing dilutions of n-butanol in concentrations from 0.0930% in a glass bottle with a first serial number to 7.178% in a glass bottle with a twenty-fifth serial number, for testing threshold capacity for smell. Second bearing panel contains 20 consecutively numbered glass bottles with olfactants with 20 aromas, one aroma in each of the glass bottles, in the form of substances: coffee, orange, garlic, mint, tangerine, onion, strawberry, lemon, apple, alcohol, fish, mowed grass, chocolate, banana, rose, melon, cucumber, raspberry, vanilla, watermelon, for testing of identification capacity of sense of smell. Instructions for use include a point scale for testing threshold capacity of smell from 0 to 25 points, where the score corresponds to the serial number of the glass bottle with n-butanol, 80 pictures with captions and a score scale for testing the olfactory identification capacity from 0 to 20 points, where the score corresponds to the correct selection of the picture with captions, wherein the instruction for use comprises 20 numbered pages, with four pictures with captions on each. One of four pictures with a signature corresponds to the substance contained in the glass bottle of the second bearing panel, and the serial number of each page of the instruction for use corresponds to the serial number of the glass bottle of the second bearing panel. In the method, at the stage of testing threshold capacity of olfaction, a substance of the first order number of the glass bottle with n-butanol diluted 0.0930 % is applied on a disposable paper blotter using a brush on the cover of a glass bottle with n-butanol. Further, a disposable paper blotter is brought to the nose of the person being tested at distance of 1-2 cm for 3 seconds, containing substance of 1st order number of a glass bottle with n-butanol diluted 0.0930%. Then disposable paper blotters are brought to the nose of the person being tested at 1-2 cm for 3 seconds with substances from glass bottles with n-butanol from 2 to 25 serial numbers. If the test subject smells the substance on the disposable paper blotter, then the test subject is brought a disposable paper blotter coated with the substance of the next index number of a glass bottle with n-butanol until the test subject reports that he smelled the substances on two disposable paper blotters from two glass bottles with n-butanol with consecutive serial numbers, and points are assigned corresponding to the last serial number of the glass bottle with n-butanol, the smell of the substance of which was smelled by the test subject. If the person being tested does not smell the substance on the disposable paper blotter, the disposable paper blotter coated with a substance from a glass bottle with n-butanol with a serial number is brought through one glass bottle with n-butanol which is greater than the serial number of the previous glass bottle with n-butanol. Then, at the stage of olfactory identification capacity testing, the disposable paper blotters, one aroma each, are coated with substances with a brush on the cover of a glass bottle with an olfactant with an aroma, from glass bottles on the second bearing panel. Then the person being tested opens a page of the instruction for use containing 20 numbered pages with four pictures with captions on each one. Further, a disposable paper blotter is brought to the nose of the person being tested at 1-2 cm for 3 seconds, and the person being tested selects one of four pictures with a signature. For each correctly selected picture with captions, a point is assigned, and the obtained points for the test stage of the identification ability of smell are summed up. That is followed by summing up the total score at the stage of the threshold olfactory capacity test and the total score at the stage of the test of the identifying olfaction capacity of the person being tested. If total score makes 0, anosmia is diagnosed. If total score makes 0 to 34 points, hyposmia is diagnosed. If total score is more than 34 points, normosmia is diagnosed.

EFFECT: more effective evaluation of olfactory capacity.
