Description

Olfactory nerve measuring system and its olfactory material injection device {Measurement system for olfactory nerve function and Apparatus for injecting olfactory material}

The present invention relates to a olfactory nerve measurement system and a device for injecting olfactory substances used in the system, in particular, by administering olfactory substances into the nasal cavity and analyzing the brain waves according to the olfactory nerves to objectively check the state of the olfactory nerve. A measurement system and an olfactory material injection device.

In general, the olfactory device is a device for objectively examining the functions of the olfactory nerve and the trigeminal nerve, and may be applied to the field of measurement of taste or inspection of pollutants.

In recent years, pollution has become serious with the development of the industry, and various problems have occurred accordingly. An example is the olfactory nerve damage of the human body, which is the part that performs the function of smelling and taste. Thus, damage to the olfactory nerve can interfere with normal human activity.

Damage to the olfactory nerves can be caused by continuous exposure to strong olfactory substances or direct destruction of the nerve tissues. In the former case, people living near sources of pollutants, or strong olfactory substances, such as around garbage dumps, Occurrence of olfactory nerves or intranasal diseases are occurring in people. In the latter case, the olfactory nerve is damaged by an injury such as a traffic accident.

Since most of the smell is performed by the olfactory nerve when the person ingests food, the damage of the olfactory nerve causes various problems in the daily life of the person, thereby causing damages. At this time, another dispute arises because there is no device for objectively checking the degree of damage to the olfactory nerve.

In the conventional case, as a method of checking the degree of damage to the olfactory nerve, a doctor of a reliable hospital injects a specific olfactory substance into the nasal cavity of the subject while changing the concentration, and asks the subject to answer the question of the degree of damage to the olfactory nerve. Judging. However, since the result of the method is determined by the testee's answer, the authenticity of the test result may be deteriorated even when the testee answers the falsity with a malice.

The present invention has been made to solve the above problems, the object is to inject a specific olfactory material into the nasal cavity of the subject and to detect the brain waves in response to it to determine the degree of damage of the olfactory nerve to improve the reliability of the test results It is to provide an olfactory neurometry system.

In addition, the present invention by making a database of the measurement results and test results for a number of human body to determine the degree of damage to the olfactory nerve by the comparison operation between the normal EEG response to the olfactory substance and the measurement result after the detection of brain waves It is to provide an olfactory nerve measurement system that can perform an olfactory neurological examination quickly and at the same time an objective and quantitative analysis.

Another object of the present invention is used in the olfactory nerve measurement system to provide an olfactory material injection device that can be selected by injecting the olfactory material air or adjust the concentration, humidity, temperature of the injected material as necessary to the human body to measure the olfactory nerve It is.
