Description

  The present invention relates to an artificial respirator mask used particularly for medical purposes, and more particularly, when the mask is held and attached to a sick person, the mask is accurately grasped to surround the nose and mouth of the sick person. The present invention relates to an artificial respirator mask that can be securely crimped onto a mask.

  Conventionally, many artificial respiration masks have been proposed for assisting breathing for a sick person whose breathing has stopped due to illness or accident. A general respirator mask is formed in a substantially dome-shaped cross section (or a substantially elliptical cross section) so as to airtightly cover the vicinity of the nose tip and the nasal bone, and both cheeks and the mouth. Is provided with a supply / exhaust hose connection port to be connected to a pump hose (see Patent Document 1).

  Also, such a conventional artificial respirator mask is a rubber-like elastic material for soft and good adhesion to the victim's face when worn on the face around the mouth and nose of the victim. And is devised to further reduce air supply leakage.

By the way, many of the current artificial respirator masks are designed on the premise that they are used by medical professionals in the medical field or in an ambulance. Therefore, when an ordinary person wears an artificial respirator mask and attaches it to an injured person in an emergency, it is slippery if it is troublesome, accidentally worn, sweated, etc. The present situation is that the structure is not necessarily effective for the victim and the general user.
