Description

TECHNICAL FIELD The present invention relates to a medical oxygen mask, and more specifically, it has an opening in a portion corresponding to the user's mouth when worn by the user, and a door provided in the opening is opened and closed so that the mouth is closed. It relates to a medical oxygen mask that can expose the

In the medical field, a medical oxygen mask is used that is worn on the face of a user such as a patient to administer oxygen. Such a medical oxygen mask is disclosed in Patent Document 1, for example. A medical oxygen mask generally covers a user's nose bridge, lower chin, left and right cheeks, is worn in close contact with the user's face, and is connected to a tube that supplies oxygen. Therefore, for example, it is extremely troublesome to remove the mask each time a user eats or drinks, or a medical worker performs a medical procedure such as sucking sputum.

As sanitary masks other than medical oxygen masks, masks with openable lids and fasteners have been proposed. Patent Literature 2 proposes a mask including an opening provided in the central portion of the mask body (the portion corresponding to the user's mouth) and a cover piece that covers the mask body so that it can be opened and closed from the front side. Further, Patent Document 3 proposes a mask having an opening in a mask body for covering at least part of a user's face. This opening can be opened and closed with a fastener.

These masks are used by healthy people to prevent pollen and to catch colds. Breathing can be improved without removing the mask, and it is possible to eat small foods and use straws, but for inpatients who have difficulty moving their bodies freely, opening and closing the lid , it is difficult to hold the open lid piece in that state. Also, since it is not a medical oxygen mask, it is not designed to be used for medical procedures such as suctioning sputum.
