After the SARS epidemic situation in 2003, medical protective masks are widely used in the medical and health field to protect the personal health of medical workers from infection by viruses and bacteria that can be transmitted through air, spray, or blood splash during operation. The requirement for wearing a medical protective mask is that the mask must be in close contact with the face to some extent. If the face shape does not conform to the shape of the mask, a close fit cannot be achieved, and failure of respiratory protection may result, leading to exposure of medical workers to occupational risk.
At present, the current effective regulations have relevant requirements on the tightness between the mask and the face, such as: the importance of the tightness is clearly indicated in 3.1.25, 3.1.26, 3.1.27 and 3.1.28 of GB/T18664-2002 respiratory protection articles; the requirements of 3.2 and 3.3 of GB 19083-2010 medical protective mask technical requirements are also provided for the sealing degree of the medical protective mask.
At present, the medical protective mask legally sold in China is not of various types, and the medical protective mask purchased by disease prevention and control institutions and medical institutions at all levels mainly takes imported products as main materials. However, the development and the development of imported products are separated from the characteristic facial features of Chinese people. For example, a brand of N95 medical protective mask has a market share of over 50%, but the shape of the mask was developed according to the face store provided by the united states military in the 70 s. In addition, research and development of medical protective masks produced by domestic manufacturers lack strict development basis, and most of the medical protective masks do not refer to any face type library of recognized authority level. The reasons directly lead to that the medical protective mask on the market can effectively fit the face shape of the Chinese to achieve the airtight proportion in the practical application and is not high; in addition, the medical protective mask produced in quantity is relatively fixed in size and cannot be completely and effectively matched with all face shapes. The applicant has found from recent studies that the sealing efficiency of the currently used main stream medical protective mask to the face is not more than 60%.
The prior art is blank on how to improve the fit between the mainstream medical protective mask and the face of the user. As an end user who purchases a medical protective mask in the market, there is no good method to increase the adhesion between the mask and the face shape on the premise that the shape and structure of the medical mask sold in the market in the prior art cannot be changed.
There is a need for improvement.

Detailed Description
Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1 to 4, the special densification ring for a medical protective mask provided by the invention comprises an annular densification ring body 1 sleeved on the edge of a medical protective mask 2, and the outer periphery 10 of the densification ring body 1 is matched with the edge 20 of the medical protective mask in shape. The densifying ring body is attached to the nose and cheek of the user, and the densifying ring body can be made of various suitable soft adhesives, such as TPU, TPE, TPR, TPV, TPES, CPE, EVA, POE, soft PVC, soft silica gel, etc. In view of comfort and safety of wearing, the mask is preferably made of silica gel and is injection molded according to the shape of the medical protective mask. The densifying ring body 1 comprises a first body 11 for being attached to the outer surface edge of the medical protective mask 2, and a second body 12 arranged on the inner surface edge of the medical protective mask and used for being attached to the face of a user, wherein the outer periphery of the first body is connected with the outer periphery of the second body, and the inner periphery of the first body and the inner periphery of the second body are separated from each other.
The middle area between the inner periphery and the outer periphery of the second body is an arc-shaped protruding part 13, a positioning notch 15 used for being attached to the nose bridge of a user is arranged on the inner periphery of the second body 12, and protruding parts 16 used for being attached to the two sides of the nose bridge of the user are arranged on the two sides of the positioning notch 15 on the second body. When in use, the convex part 13 with the arc-shaped middle area between the inner periphery and the outer periphery of the second body 12 has a three-dimensional shape, so that the tightness of the face is increased; in addition, the positioning notch 15 is just clamped on the nose bridge, and the bulge 16 has a three-dimensional shape and is tightly attached to the two sides of the nose bridge, so that the tightness between the bulge and the nose bridge and between the bulge and the two sides of the nose bridge is improved.
As shown in fig. 4, the second body 12 is provided with a rib 18 extending from the outer periphery to the intermediate region, and the second body 12 has a larger thickness at the portion where the rib is provided, and the second body 12 has the same thickness at the portion other than the rib portion. The ribs 18 support the middle region convex part 13, and further increase the adhesion between the densifying ring and the face.
Preferably, the width of the first body 11 (i.e. the radial distance between the inner periphery and the outer periphery of the first body) is greater than or equal to 0.5cm.
The inner periphery of the first body is provided with 4 second positioning notches 14 at positions corresponding to the head band nodes of the medical protective mask, and the positions of the 4 second positioning notches 14 are matched with the 4 head band nodes 21 of the medical protective mask. The densifying ring reserves positions at the 4 positions to avoid the joint of the head belt, so that the fitting of the silica gel component and the outer surface of the mask is tight, and the accidental entry of pollutants is avoided.
Two transverse blocking belts 17 are arranged on the first body 11 so as to prevent the mask from overflowing or shifting outwards in the wearing process. And the first body 11 with the blocking tape should be positioned on the outer surface of the mask to remind the user not to reverse the packing of the densifying ring. The length of the blocking tape 17 is adapted to the shape of the mask.
When the medical mask is used, the positioning notch 15 of the densifying ring is aligned with the nose bridge part of the medical mask, the densifying ring is entirely sleeved on the edge of the medical mask (the mask is plugged in from a gap between the inner periphery of the first body and the inner periphery of the second body, the densifying ring can be conveniently sleeved on the mask due to the fact that the densifying ring is made of soft rubber), the head bands of the medical mask are arranged, the positions of the limiting notch 14 and the head band node 21 are adjusted again, the positioning notch 15 is well matched with the nose bridge part of the medical mask, and then the medical mask provided with the densifying ring is put on. The outer surface of the original medical protective mask is provided with a metal nose clip 22, and the metal nose clip 22 is covered by a densifying ring. Because the densifying ring is soft, the nose clip 22 can still be pressed by hand to adjust the sealing of the nose bridge part, and pressing the metal nose clip 22 can also increase the fitting degree of the densifying ring to the face.
