Description

Mask

Technical Field

The utility model relates to the technical field of medical equipment, in particular to mask.

Background

The medical mask is an indispensable two-way protective article for medical staff. Medical masks must be worn prior to medical procedures, even during rounds. The protective effect of the medical mask is good and bad, and is directly related to the selection of the medical mask, whether the medical mask is worn correctly or not and the attaching degree of the mask and the face. Particularly in the case of preventing the spread of infectious diseases, wearing protective gear for a long time causes the following problems: 1. facial pressure trauma (nose and cheek location); 2. the posterior auricle may also cause trauma due to the pulling and friction of the mask strap.

The traditional medical mask consists of a mask body and a tightening belt, wherein the mask body is divided into an inner layer, a middle layer and an outer layer, the inner layer is made of a skin-friendly material (common sanitary gauze or non-woven fabric), the middle layer is an isolation filter layer (superfine polypropylene fiber melt-blown material layer), and the outer layer is a special material antibacterial layer (non-woven fabric or ultrathin polypropylene melt-blown material layer). The method is divided into the following steps according to performance characteristics and application range: medical protective masks, medical surgical masks, and ordinary medical masks. The requirements of different products of the mask are different according to related national or industrial standards, and because the mask is provided with the nose clip which is made of bendable plastic materials (the length of a bone clip of the medical protective mask is more than 8.5cm, and the length of the nose clip of the medical surgical mask is more than 8.0cm), and the nose clip is made of full plastics, iron wires or aluminum strips and the like, when the infectious disease epidemic situation is resisted, a front-line medical worker wears the medical mask for a long time, and the pressure of the nose bridge strip at the position of the nose clip on the face for a long time causes pressure damage to the positions at two sides of the nose and the cheekbone.

The tension band of the existing medical mask is generally designed as an ear band or a self-binding band, and the medical mask is hung behind ears or fixed on the head by the self-binding band when being worn. And the convenience probably leads to during the in-service use not enough, appears wearing to tighten when protecting for a long time especially and takes fixed behind the ear, leads to behind the auricle also can cause the wound because of the pulling force and the frictional force of gauze mask area.

SUMMERY OF THE UTILITY MODEL

For solving at least one among the above-mentioned technical problem, alleviate facial pressure damage, the utility model provides a gauze mask, the technical scheme who adopts as follows:

the utility model provides a gauze mask includes the gauze mask face body and taut subassembly, the gauze mask face body includes outer bacteriostasis layer, middle level filter layer, inlayer close skin layer and bridge of the nose strip, inlayer close skin layer is corresponding hydrogel layer has been arranged to bridge of the nose strip's position.

Further, the width of the hydrogel layer is at least twice the width of the nose bridge strip.

Further, the length of the hydrogel layer is greater than the length of the nose bridge strip.

Further, the thickness of the hydrogel layer is greater than or equal to 1.5 mm.

Furthermore, the thickness of the middle part of the hydrogel layer corresponding to the nose bridge strip is thicker, and the thickness of the rest parts of the hydrogel layer is thinner.

Furthermore, the tensioning assembly comprises two tensioning belts connected with the mask body, and the two tensioning belts are fixed on the back side of the head.

Furthermore, the two tensioning belts are fixed through magic tapes.

Further, the tightening strap has elasticity.

Has the advantages that: the mask body is provided with the hydrogel layer corresponding to the position of the nose bridge strip in the inner layer skin-friendly layer, so that the nose bridge strip directly presses the facial skin when the mask body is worn, and the hydrogel layer helps to relieve the pressure on the face. The utility model can be widely applied to the technical field of medical instruments.

Detailed Description

The present invention will be further described with reference to fig. 1 to 2.

The utility model relates to a mask, it includes the mask face body 11 and taut subassembly, and the mask face body 11 includes outer antibacterial layer, middle level filter layer, inlayer close skin layer and bridge of the nose strip 12, and the mask face body 11 adopts stacked structure, can pull open the enlarged area in order to cover the oronasal completely and extend to the chin position during the use. The outer bacteriostatic layer is made of non-woven fabric with water repellency, and can block splashed liquid. The middle filtering layer is made of melt-blown non-woven fabric, and the superfine fibers with unique capillary structures increase the number and the surface area of the fibers in unit area, so that the melt-blown non-woven fabric has good filtering property, shielding property, heat insulation property and oil absorption property. The inner skin-friendly layer has good hygroscopicity and can absorb moisture in mouth and nose.

The inner skin-friendly layer is provided with a hydrogel layer 13 at a position corresponding to the nose bridge strip 12, and the hydrogel mainly comprises deionized water, a plurality of high molecular copolymers, a cross-linking agent and the like.

The width of the hydrogel layer 13 is at least twice the width of the nose bridge strip 12, and the length of the hydrogel layer 13 is larger than that of the nose bridge strip 12, so that the pressure of hydrogel on the face when the mask is worn is reduced. The thickness of the middle part of the hydrogel layer 13 corresponding to the nose bridge strip 12 is thicker, the thickness of the rest parts of the hydrogel layer 13 is thinner, and the hydrogel layer 13 presents downhill amplitude distribution. To the design of hydrogel layer 13 structure, can provide effective protection for bridge of the nose strip 12 position, hydrogel layer 13 is as isolation structure because of its moist, soft feel, makes bridge of the nose strip 12 can not direct and facial skin contact, avoids causing pressure and leading to skin red, impression, broken skin scheduling problem to facial skin appearance.

Because the deionized water content in the hydrogel layer 13 is more than 90%, the hydrogel layer 13 becomes thin due to the gradual volatilization of the moisture when the hydrogel layer is in contact with the air, and therefore the thickness of the designed hydrogel layer 13 is more than or equal to 1.5mm, and the moisture of the hydrogel layer 13 of the mask which is worn for a long time can not be completely volatilized.

The hydrogel is rich in moisture, can reduce the temperature of a wound surface, relieve pain, prevent the wound surface from deepening and accelerate wound healing, has a unique polymer reticular structure, can effectively block bacteria and prevent infection, has good biocompatibility, can ensure that the wound is not adhered, and has good fitting property. As a material of the mask, the mask has a prevention effect on facial pressure injury which is easy to appear after long-term wearing, can further improve the existing problems of skin redness, impression, skin breakage and the like, and is convenient for rapid wound healing.

The tightening assembly comprises two tightening straps 14 connected with the mask body 11, the tightening straps 14 have elasticity, and the two tightening straps 14 are fixed on the back side of the head. When the novel ear pad is worn, the novel ear pad does not cause pulling force and friction force behind the ear, and can effectively bring about the wound caused by long-time wearing and use.

For convenient use, the two tightening straps 14 are fixed by a magic tape.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
