Abstract

An olfactory quantification device and system with improved accuracy are disclosed. According to one aspect of the present embodiment, an olfactory quantification system for objectifying and quantifying what kind of scent a subject smells is perceived as, comprising: a testing device attached to or mounted on a pre-set part of the subject to test the functional activity of the left and right prefrontal lobes; and an olfactory quantification device that analyzes the results of the testing device to quantify the type of scent perceived by the subject, wherein the olfactory quantification device comprises a power supply unit, a control unit, an analysis unit, a memory unit, and an adjustment unit.

  1. In an olfactory quantification system that objectifies and quantifies how a subject smelling a scent perceives it, A testing device that is attached to or mounted on a pre-set area of a subject to test the functional activity of the left/right prefrontal cortex; and It includes an olfactory quantification device that analyzes the results of the inspection device described above and quantifies the type of scent perceived by the subject, The above-mentioned olfactory quantification device is an olfactory quantification system characterized by including a power supply unit, a control unit, an analysis unit, a memory unit, and an adjustment unit.
  2. In paragraph 1, The above analysis unit is, An olfactory quantification system characterized by deriving the concentrations of oxyhemoglobin and deoxyhemoglobin after the scent is provided, based on the results of an inspection by the above inspection device.
  3. In paragraph 2, The above analysis unit is, An olfactory quantification system characterized by analyzing the degree and pattern of activation of both prefrontal cortexes based on each derived hemoglobin concentration.
  4. In paragraph 2, The above analysis unit is, An olfactory quantification system characterized by comparing the degree and pattern of activation of both prefrontal cortexes with those stored in the memory unit to quantify what kind of scent the subject perceives the currently provided scent as.
  5. In paragraph 1, The above memory unit is, An olfactory quantification system characterized by storing the degree and pattern of prefrontal cortex activation when humans perceive each scent.
  6. In paragraph 5, The above adjustment unit is, Specifically, an olfactory quantification system characterized by determining whether the degree of activation of both prefrontal cortexes exhibits a pattern stored in the memory unit.

Description

Olfactory Quantification Apparatus and System with Improved Accuracy The present embodiment relates to an olfactory quantification device and system that quantifies the scent perceived by a subject by quantifying the brain pattern of the subject smelling a scent, while improving the accuracy of the quantification. The content described in this section merely provides background information regarding the present embodiment and does not constitute prior art. There are often cases where it is necessary to determine whether a subject's sense of smell is intact, such as when identifying a dementia patient or determining whether a worker's loss of olfactory function constitutes an industrial accident. Typically, the integrity of olfactory function is assessed by providing a specific scent to the subject and listening to their response regarding what kind of scent they smelled. However, conventional methods have a problem in that the reliability of the subject's response is low. There may be cases where the subject intentionally answers with a different scent even though they have smelled and recognized the scent accurately with a specific purpose, or cases where they answer with a scent that matches the provided scent by accidentally giving a different answer even though they have recognized a scent different from the provided scent. In the past, when it was necessary to objectively determine whether a subject's sense of smell was intact, inaccurate judgments were inevitable because the determination of whether the subject had lost their sense of smell had to rely on the subject's answers.
