Medical protective mask

Abstract

The invention relates to a medical protective mask. The mask comprises a mask body and adjustable fixing bands penetrating out of the two sides of the mask body. The mask body comprises an upper piece, a body and a lower piece which are sequentially connected and are narrow on the two sides and wide in the middle. A nose wire is arranged at the upper edge in the upper piece. The adjustable fixingbands are arranged on the upper edge of the interior of the upper piece in a tight fit and penetrating manner, penetrate out to the outer side of the upper piece from the positions, which do not exceed the length direction of the nose wire, of the two ends of the upper piece, and penetrate through positioning belt buckles arranged in the middle of the outer side of the upper piece and corresponding to the nose wire in position. The overall filtering structure and mounting structure are more reasonable, the mask body is attached to the face outline, and reasonable stress included angles are formed between the mask body and the adjustable fixing bands in the up-down direction, so that the sealing performance of the mask body is protected, the size of the dead space is small enough, the gas exchange area during breathing is enlarged, and the mask is safe and comfortable to use.

Description

technical field [0001] The invention relates to a medical protective equipment, in particular to a medical protective mask. Background technique [0002] At present, the common types of masks on the market usually have two structures. One is the flat type. Ergonomic cutting, as well as high-tension adjustable fixing straps and other fixing methods, achieve better protection effects, and are often used in high-demand occasions such as hospitals. [0003] The common flat masks on the market have failed to solve the problem of air tightness, especially at the bridge of the nose. It is difficult for the mask body to fit closely with the skin on the bridge of the nose, making it easy for outside air to pass through the gap between the bridge of the nose without filtering. be inhaled. Planar masks are usually equipped with plastic nose clips to reduce the gap at the bridge of the nose, but the effect of tight fit is still not achieved. The nose clip of a flat mask is usually th...

Problems solved by technology

[0007] It can be seen that the above common masks all have shortcomings such as simple design, poor protective effect, and poor long-term use experience.

In medical occasions that require high protection efficiency and long-term use of masks, the above-mentioned masks cannot meet the ideal use requirements
