In the illustrated example, a diffusion fan 176 is provided on the first flow path 174 and the second flow path 175 , respectively.

Chlorine dioxide is applied to have a concentration that is not harmful to the human body, and when sprayed, it can sterilize surface bacteria, airborne bacteria, dropping bacteria and even bacteria with a HEPA filter in the body 110 .

When the active light source 177 and the diffusion fan 176 are operated, the chlorine dioxide ejection unit 170 is a first flow path 174, a gas generating space 173, The sterilization process is performed while air is circulated along the circulation path leading to the second flow path 175 and the accommodation space 112 .

The human body detection sensor 181 is installed in the receiving space 112 of the main body 110 to detect whether there is a human body in the receiving space 112 and provide it to the control unit 200 .

The human body detection sensor 181 is installed to detect the distance from the opposite wall of the body 110, and a distance sensor that detects a human body by a change in a measured distance value depending on the presence or absence of a human body, or a human body by detecting infrared rays radiated from the human body. It can be applied in various ways, such as a method of detecting presence or absence.

Reference numeral 183 denotes an exit button that is pressed when exiting the room.

The collection glove 190 extends from the outside of the main body 110 to the inside of the receiving space 112 so that it is possible to manually collect a sample from the subject while maintaining a shielding state with the outside of the receiving space 112. have.

The collection glove 190 has elasticity like a rubber material and is formed so as to be able to perform work by hand in a state in which both hands of the human body are inserted.

Reference numeral 194 denotes a protective door that shields the collecting gloves 190 from being exposed to the outside when not in use, so that the collecting gloves 190 installation area can be opened and closed to the outside. In addition, reference numeral 184 is a see-through window made of a transparent material so that the inside of the main body 110 can be seen through the upper portion of the protective door.

The shelf 196 is installed in a position adjacent to the collection gloves 190, and a sample container or kit for collecting samples is temporarily placed to accommodate the samples collected from the inside of the nose or throat of the subject with a cotton swab for sample collection. It provides an area for space.

The sterilizing water supply unit 220 is configured to supply sterilizing water to the surface of the collecting gloves 190 for sterilization. The sterilizing water supply unit 220 is constructed as a reservoir 222 in which the sterilized water is stored and a jet container 224 that temporarily stores the sterilized water supplied from the reservoir 222 and discharges the sterilized water by operating the lever 224a. have. A valve (not shown) for controlling the supply of sterilizing water is mounted on the sterilizing water supply passage leading from the reservoir 222 to the jetting vessel 224 . A level sensor that detects the amount of stored sterilizing water and provides it to the control unit 200 may be mounted in the jetting container 224 .

The control unit 200 controls the operation of the locking unit 121 , the negative pressure unit 150 , and the chlorine dioxide ejection unit 170 .

In addition, when a human body is detected by the human body sensor 181 , the control unit 200 outputs an announcement to guide the sample collection process through the speaker 185 mounted inside the body 110 .

Here, the announcement may be constructed to reproduce the recorded audio file corresponding to the set sample collection process.

When the sample collection process is completed and a signal that the exit button 183 is manipulated is received from the subject, the control unit 200 processes the lock unit 121 to be unlocked, and the body detects the body from the signal received from the sensor 181 . When it is determined that there is no human body in 110, the sterilization mode is performed by controlling the combustion of chlorine dioxide to be ejected into the body 110 from the chlorine dioxide ejection unit 170.

The display unit 187 is installed on the upper part of the main body, and a green lamp 187a for emitting green, a yellow lamp 187b for emitting yellow, and a red lamp 197c for emitting red are applied.

The display unit 187 is controlled by the control unit 200, so that the green lamp 187a is turned on when it is usable, the yellow lamp 187b is turned on when a sample is being collected, and the red lamp 187c is turned on when it is being sterilized. processed

Reference numeral 240 is provided to make a call with the outside through the intercom.

The emergency button 250 is provided on the outside of the main body 110 and the inside of the main body 110 , respectively.

The emergency button 250 is applied to instruct to forcibly unlock the door while the door is locked by the lock 121 of the main body 110, and is applied when it is determined that protective measures for the subject are necessary. .

The control unit 200 processes the lock unit 121 to be unlocked when the emergency button 250 is operated.

Unlike the illustrated example, the emergency button 250 may be provided only outside the main body 110, of course.

On the other hand, the sample collecting worker who collects the sample from the subject collects the sample using the test kit provided in the main body 110 using the collecting glove 190, and when the body sampling operation is completed, the sterilizing water supply unit 220 is ejected. It is enough to sterilize the collecting gloves 190 with the sterilized water supplied through the container 224 .

According to the booth for collecting samples for patients with respiratory infections, it is possible to safely collect a sample from a subject using a collection glove and provides the advantage of increasing the sample collection efficiency.
