Description

In the present invention, for example, the presence or absence of infection with the so-called new coronavirus (COVID-19) can be easily confirmed, and a safe collection operation is performed in a state of being isolated from the subject to be inspected. Regarding the booth device for sample collectors such as infectious diseases that made it possible to carry out.

Conventionally, it has been generally practiced to prevent the spread of infection to the surroundings by isolating a patient suffering from an infectious disease. In addition, whether or not the patient is infected is determined by culturing a part of the body of the subject, for example, a part of the secretion collected from the body, or confirming by a predetermined determination method using the test kit. In order to prevent infection, it is necessary to detect the infected person at an early stage, and to take appropriate measures such as hospitalization isolation, follow-up, and other appropriate measures according to the symptoms of infection.

Therefore, even if it is necessary to collect a part of the mucous membrane / secretion in the oral cavity from the subject in order to confirm the presence or absence of infection and the situation of the subject, the collector will be in direct contact with the subject. You may be infected. If the collector himself is infected in this way, the risk of spreading the infection, such as infecting an uninfected subject, is further increased.

In particular, when the infectivity is strong and it is necessary to avoid physical contact or approach with the subject, it is necessary for the collector to wear a state in which infection protection measures are taken, for example, infection protection clothing. .. Even if you wear an infection protection suit, you need to be very careful when putting it on and taking it off, and you may be infected by contact with bacteria or viruses that have adhered to the outside of the infection protection suit. Moreover, such infection protective clothing is expensive, and even if it is replaced every time it is collected, it is troublesome to dispose of it, which is a heavy burden.

In order to prevent such an infection risk, for example, a sterile room shown in Patent Document 1, a unit-type examination room shown in Patent Document 2, a portable unit-type examination room shown in Patent Document 3, and the like have been proposed. The aseptic chamber of Patent Document 1 purifies the sterile chamber formed by partitioning the chamber, sucks air from the outside of the sterile chamber, and keeps the sterile chamber at a positive pressure. In the unit-type examination room of Patent Document 2, the patient information acquisition unit acquires patient information regarding the patient's condition, and the preparation information generation unit generates examination preparation information necessary for examination based on the patient information. The portable unit type examination room of Patent Document 3 is configured to be used independently by transporting and installing an examination room equipped with a medical diagnostic device and a power supply device to a disaster area or the like by means of transportation.

However, the sterile room of Patent Document 1 merely sterilizes the living space of the patient who receives treatment and nursing all day, and considers the safety of the collector when collecting various samples from the patient in this sterile room, for example. It's not a thing. In the unit-type examination room of Patent Document 2, even if patient information is acquired, it does not prevent infection to the collector by collecting a sample from the patient and making a diagnosis. In the portable unit type examination room of Patent Document 3, even if it is convenient to carry out independent examination work in a disaster area where transportation is installed, it is not possible to safely collect samples from the subject. do not have.

In any case, for example, in the case of the new coronavirus (COVID-19), which has particularly strong infectivity, there is a risk that physical contact with the subject and inhalation of droplets and other substances emitted from the subject may occur. be. In order to prevent this, even if the collector wears infection protection clothing, etc., he or she often lives temporarily with the subject in a certain space at the time of collection, and in addition, contact with the person when putting on and taking off infection protection clothing, etc. The reality is that it cannot be completely removed.

Therefore, the present invention was created in view of the above-mentioned conventional circumstances, and when a sample is collected from a subject who is suspected of having an infection, the safety of the person who collects the sample is improved.
