Description

The present invention is designed to prevent tingling and coughing caused by the gag reflex of the subject when performing oral or nasal endoscopy targeting the upper gastrointestinal tract (esophagus, stomach, duodenum), pancreas, biliary tract, etc. This invention relates to medical infection protection equipment that protects healthcare workers from exposure to infectious disease agents caused by dispersed droplets.

In January 2020, the World Health Organization announced that the new coronavirus was the cause of an outbreak of pneumonia, and in the same year it rapidly spread to countries around the world, causing many infections and deaths.

Because the virus can be transmitted even during the asymptomatic stage after infection, it is difficult to contain it, unlike past coronaviruses such as SARS, which are transmitted only after symptoms develop, especially among medical workers who come into contact with sick and sick people on a daily basis. If infected, there is a problem that not only does it pose a risk of secondary infection, but it can also impede the provision of medical care and lead to medical collapse.

On the other hand, there is an increasing number of cases in which patients who should have been treated by the virus are refraining from going to medical institutions due to fear of being infected with the virus, and the symptoms of those who should have been treated are getting worse.We are developing measures to suppress concerns about infection. This has become an important issue.

Regarding the infection route of the virus, droplet infection from respiratory secretions is considered to be the most important route of infection, but considering the cases of infection, the possibility of airborne infection cannot be ruled out, so there is no clear conclusion. However, medical institutions are taking various infection prevention measures to prevent in-hospital infections, such as disinfecting the hospital, wearing masks and protective clothing, and isolating treatment routes for patients suspected of being infected with the virus. We are taking measures.

In order to prevent secondary infection with the virus, it is necessary to isolate infected people and prevent the virus from spreading to the surrounding area, but since it can be transmitted even when the virus is asymptomatic after infection, it is expensive and expensive for medical institutions. There are many treatment tools that cannot be easily transported, making it difficult to apply them to all patients.

In order to solve the above problems, Patent Document 1 discloses that it is possible to expand the entire sheet into a plate-like sheet, the material of the sheet is translucent plastic, and the sheet indicates the part where the sheet is folded. It is equipped with a linear bending guide, and when it is bent and installed between the user and the person facing the person, it has a substantially rectangular front surface that blocks the user and the person facing each other, and a front surface as seen from the user. The bending guide further includes a left side having a substantially rectangular shape that is continuously connected to the left side, and a right side having a substantially rectangular shape that is continuously connected to the right side of the front surface as viewed from the user. Droplet infection prevention shields are listed on the left and right sides.

However, the medical infection protection device described in Patent Document 1 has the effect of preventing droplet infection when a medical worker and patient are face-to-face, but it is effective for preventing oral or nasal infection when the patient is lying down. This is not the case in endoscopy; even if the subject has no symptoms of coughing, if the endoscopy scope touches the pharynx or base of the tongue, tingling may occur due to the gag reflex. This poses a problem in that medical workers such as doctors and caregivers may be exposed to the air as they choke and cough, causing droplets to fly.
