Description

Self-adhesion closed medical mask

Technical Field

The utility model relates to a gauze mask technical field, concretely relates to medical gauze mask of self-adhesion closed.

Background

The mask is a sanitary article, and is generally a tool which is worn at the mouth and nose part and is used for filtering air entering the mouth and nose so as to prevent harmful gas and spray from entering and exiting the mouth and nose of a wearer. The mask has a certain filtering function on air entering the lung, and has a very good effect when being worn in respiratory infectious diseases and working in environments polluted by dust and the like. The protective mask is a respiratory protection article aiming at preventing the transmission of some respiratory infectious microorganisms and protecting the health. The material for filtering the particles comprises mineral fibers, natural fibers or synthetic fibers, and the filter material fibers have five mechanisms of filtering the particles in the air, specifically comprising a settling effect, an inertia impact effect, an interception effect, a diffusion effect and an electrostatic effect, which can comprehensively play a role. The main factors influencing the effectiveness of the mask are two, namely the filtering efficiency of the filtering material and the suitability of protective articles and users. If the protective article can not be tightly combined with the face of a user, harmful substances in the air can enter the inside of the inlet cover from the leakage position, and the filter material grade is higher. The current medical protective facial mask realizes and the laminating between the face through the nose clip, leads to the humid and hot gas that the user exhaled to drench glasses and gauze mask easily, simultaneously because gauze mask both sides and below do not laminate with patient's face well, leads to the protective effect of gauze mask not good.

Patent document with application number CN201020104727.1 discloses a novel medical surgical mask, which is composed of a mask, non-woven fabric, melt-spraying cloth, a pressure-sensitive adhesive tape and release paper, wherein the inner layer of the non-woven fabric is clamped with one layer of melt-spraying cloth, the pressure-sensitive adhesive tape with the length of about 7 centimeters is adhered to the middle position of the upper end of the mask close to the face, the release paper is adhered to the lower half part of the inner layer of the pressure-sensitive adhesive tape, and the whole mask has four ear belts. Can be on medical personnel's the bridge of the nose to the gauze mask adhesion, make during steam directly gets into the air through non-woven fabric, the hot-air of having avoided people's exhalation gets into the air from the top of gauze mask and leads to the lens fuzzy, but when breathing in, because the both sides of gauze mask, the laminating is limited between below and the human face, lead to in the outside air still can follow the both sides and the below of gauze mask and enter into the oral cavity cover, the protective effect is not good, and the gauze mask can still be moisturized to the moist hot-air of human exhalation, influence the travelling comfort of using.
