Description

Flexible self-sealing medical mask

Technical Field

The utility model relates to the technical field of medical health, in particular to a flexible self-sealing medical mask.

Background

The medical mask is suitable for protecting medical staff and people from respiratory tract infectious diseases transmitted by air, is a self-absorption filtering type medical protective article requiring sealing property, and belongs to a disposable product. To meet the protection requirements of wearing masks, the medical protective mask (GB 19083-2010) item 4.1 specifies that "the mask should cover the nose and mouth of the wearer and have good facial fit".

The medical surgical mask (YY 0469-2011) clause 3.1 specifies that the medical surgical mask is used for covering the nose and the jaw of a user and providing a physical barrier for preventing pathogenic microorganisms, body fluid, particles and the like from directly permeating, so that the purpose of medical protection is realized for the mask user. The medical masks have the shapes of arch, butterfly, binding, ear hanging and the like.

When a user wears the mask, the mask surface body covers the mouth and nose parts of the user in a binding or ear hanging mode. No matter the ligature is worn, or the ear is hung and is worn, the atress direction of the mask face body all stretches out towards the head back along the face to both sides, based on the three-dimensional type characteristic structure of people's face, under this kind of atress condition, because of protruding formation space between the mask face body and the facial nasolabial sulcus of user's nose, and make the mask face body and the back side of the two cheeks in user's mouth angle form the space, make medical protective facial mask become "gas leakage mask" in fact, finally lose the safeguard function to viruses such as respiratory infectious disease.

Compared with the cheek of a user, the traditional mask body has insufficient softness, and when the mask user wears the mask for a long time, the mask body easily abrades the skin of the cheek of the user to cause wound to the user.

In view of the above, an improved flexible self-sealing medical mask is now devised.
