Description

  The present invention relates to a protective device used for diagnosis and diagnosis of infectious diseases such as influenza (including new types).

  As countermeasures against infectious diseases such as influenza, when personal specialists such as doctors in medical and public health contact with patients, personal protective equipment (PPE) such as gloves, gowns, head covers or hats, masks, For example, the National Institute of Infectious Diseases Information Center for Infectious Diseases has information on the selection and attachment / removal of appropriate PPE.

  Such personal protective equipment is assumed to be worn by a doctor or the like who comes into contact with the patient, and is not supposed to be worn by the patient at the time of examination. That is, if the patient wears a mask or the like at the time of medical examination, the doctor cannot observe the redness of the mucous membrane of the patient's throat and cannot collect the specimen as described later.

  By the way, the presence or absence of influenza infection is determined by collecting nasal wiping liquid, pharyngeal wiping liquid or nasal aspirate from a patient as a specimen and examining it with a diagnostic kit.

  At this time, in the case of the nasal wiping solution, a cotton swab is inserted into the back of the nose, the mucosal epidermis is collected by rubbing the turbinate several times, and the throat cleaning solution is inserted into the back of the throat. The mucosal epidermis is collected by rubbing several times. On the other hand, the nasal aspirate is collected by inserting a suction tube into the back of the nose.

  When collecting such a specimen, especially when collecting a nasal wipe, the swab will tickle the mucous membrane of the nose, so the patient is likely to sneeze due to sneezing reflexes. In this case, the sneezing droplets are applied to doctors or scattered indoors, so if the patient is infected with influenza, the virus will scatter, which is very problematic in preventing infection. Become.

  Thus, doctors can prevent adhesion to their bodies by wearing personal protective equipment as described above against splashes from patients infected with influenza. The scattered droplets may lead to infection of the patient or the like who enters the room next time, and in order to prevent this, some removal processing must be performed, which is very troublesome.

  On the other hand, in order to protect pollen and dust from entering the eyes and nose, for example, in Patent Document 1 and Patent Document 2, air is blown by a fan to the front of a hat, a sun visor, etc. A protective device has been described which previously formed an air curtain with air.

  However, even if a doctor uses such a protective device in a medical examination / diagnosis room or the like, the problem of the process of removing the splashes scattered in the room cannot be solved.

  The problem to be solved by the present invention is, for example, in the diagnosis / diagnosis of infectious diseases such as influenza, such as prevention of adhesion of droplets from a patient to a doctor, and droplets scattered in a room from a patient or the like. There has been no proposal of means for performing the processing.

  In order to solve the above problems, in the present invention, a protection device body provided with an annular pipe can be supported at an appropriate height by a supporting means, and an air ejection portion is formed in an arc shape at a lower portion on the front side of the annular pipe. The upper surface of the annular pipe is covered with an air blocking sheet, and the air blocking sheet is suspended downward from the annular pipe so that an opening is formed on the front side. We propose a protective device for diagnosis and diagnosis that has a system that connects a series of air supply ducts and cleans and circulates the indoor air in which the protective device is installed.

  The present invention also proposes a diagnostic / diagnostic protective device having an indoor air suction part for sucking indoor air and circulating it in the above configuration at the lower part of the front side of the lower part of the protective device body. .

  The present invention also proposes a diagnosis / diagnosis protective device in which the air blocking sheet is transparent in the above-described configuration.

  In the present invention, when a doctor examines or diagnoses an infectious disease such as influenza, the annular pipe constituting the body of the protective device is positioned above the doctor's head, and the doctor blocks the air from the body hanging from the annular pipe. Enter the space surrounded by the seat and operate the clean air supply device.

  On the other hand, the patient sits in front of the opening of the air-blocking sheet on the front side of the protective device main body and receives a medical examination / diagnosis by a doctor.

  During the examination / diagnosis, the clean air supplied to the annular pipe from the clean air supply device through the air supply duct is ejected downward from the arc-shaped air ejection part to form an air curtain in front of the doctor's face.

  Therefore, even if the patient sneezes or coughs and splashes forward, the splash can be prevented from being blocked by the air curtain and hitting the doctor.

  On the other hand, the air in the room for diagnosis / diagnosis is sucked from the indoor air suction part, and at least a part of the air circulates and is cleaned by a cleaning means such as a HEPA filter or a ULPA filter in the clean air supply device. Again, an air curtain is formed in front of the doctor's face by ejecting downward from the air ejection portion of the annular pipe.

  Thus, since the air in the examination / diagnosis room is sucked from the room air suction unit and cleaned, the splashes scattered from the patient are discharged from the room together with the air and do not remain in the room.

  For this reason, there is no possibility that the spray splashed into the room from the previous patient will remain in the room and lead to infection to the doctor, the patient who entered the room next time, and the like.

  If the indoor air suction part for sucking indoor air and circulating it is provided in the lower part on the front side of the lower part of the protective device body, it is effective to remove the splashes scattered from the patient to the room by the downflow of air Can be done.

  If the air blocking sheet is transparent, it will not block the doctor's view.
