Description

Disposable medical mask

Technical Field

The utility model relates to a disposable medical mask, which belongs to the technical field of medical appliances.

Background

The common disposable medical mask is generally composed of a rectangular mask body and elastic bands sewn on the left side and the right side of the mask body. The mask body is generally in a rectangular shape formed by sewing three layers of non-woven fabrics (a skin-friendly layer, an isolating layer and a filtering layer from inside to outside), and three transverse creases are formed in the middle. The upper side edge of the mask body is sewed with a strip-shaped framework which is made of plastic materials. When the mask is used, three folds of the mask surface body are longitudinally pulled open to form a round bag shape to cover the mouth and nose, the nose clip is pressed above the nose tip, and then the two elastic bands are tensioned and then sleeved on the back of the two ear roots.

The medical mask is simple and practical, low in price and strong in air permeability, has a remarkable filtering effect on most harmful dust and viruses, and is very widely applied clinically. However, the mask is fixed by tightening the elastic band and then fixing the elastic band at the back of the ear root, the ears of a person are usually higher than the mouth, and in practical use, the elastic band hung on the ear root has upward pulling force on the mask surface body, so that the mask surface body gradually moves upwards after the mask is worn for a long time, the sight is blocked, and a user has to frequently pull the mask surface body downwards for resetting. Particularly, when the user is talking or operating with his head down, the mask body is displaced upward more significantly, which seriously affects the viewing and wearing comfort of the user.

Disclosure of Invention

In order to improve the wearing comfort and the good experience of the mask, the utility model provides a disposable medical mask which is reformed based on the original disposable medical mask and can effectively avoid the influence on the sight line caused by the upward movement of the mask surface body.

The purpose of the utility model is realized through one of following technical scheme at least.

A disposable medical mask comprises a mask body 7 and elastic bands 6 on both sides of the mask body. The mask surface body 7 is provided with an arc nose clip 2, a double arc groove 3, a fold layer 4, a wave framework sewing hole 5 and a wave framework 1; the double arc-shaped grooves 3 are arranged on the upper side of the mask surface body 7; a seaming channel is seamed below the double-arc-shaped groove 3 along the edge of the upper side of the mask body 7 by using a thread, a wavy framework 1 is seamed in the seaming channel, a seaming hole 5 of the wavy framework is arranged at one end of the seaming channel, and the part of the wavy framework 1 protruding upwards is an arc-shaped nose clip 2; the middle part of the mask surface body 7 is provided with a wrinkled layer 4.

Further, the wavy framework 1 is made of deformable plastic materials with the width of 1 mm-3 mm, is long-strip-shaped before being inserted, and is deformed into the wavy framework after being inserted into the seaming channel from the wavy framework seaming hole 5.

Further, the double-arc-shaped grooves 3 are two arc-shaped grooves with the width of 4 cm-6 cm and the depth of 1.5 cm-2.5 cm.

Furthermore, the arc nose clip 2 is a part protruding upwards in the middle of the wavy framework 1, and is symmetrically attached to two sides of the nose wing of a human body, so that the mask is natural and attractive to wear.

Furthermore, the mask surface body 7 is formed by sewing three layers of non-woven fabrics together, and comprises a skin-friendly layer, an isolation filter layer and an antibacterial layer from inside to outside.

Further, the wavy framework seam hole 5 is used for inserting the wavy framework 1 into the seam channel below the double-arc-shaped groove 3 from the wavy framework seam hole 5.

Compared with the prior art, the utility model have following advantage:

the mask is comfortable to wear and good in experience, and the influence on the sight of a wearer due to the upward movement of the mask body can be effectively avoided.
