Description

Medical protective mask with filter material grade of N95 type

Technical Field

The utility model relates to the field of medical supplies, in particular to a medical protective mask with a filter material grade of N95 type.

Background

The mask is a sanitary article, is generally worn at the mouth and nose part for filtering air entering the mouth and nose so as to achieve the purpose of preventing harmful gas, smell and spray from entering and exiting the mouth and nose of a wearer, is made of gauze or paper and the like, has a certain filtering effect on air entering the lung, and has a very good effect when the mask is worn in operation in an environment polluted by dust and the like when respiratory infectious diseases are prevalent.

The mask which is considered most effective at present is the mask which is prepared by the American disease control bureau during SARS period and is in accordance with SARS epidemic situation diffusion, and people who contact with suspected SARS cases should wear the mask which conforms to the national Institute of economic Safety and health N95 standard filter material, and the filter material of the mask is divided into three grades: one is 95 grade, which means the lowest filtration efficiency is more than or equal to 95 percent; the second is 99 grades, which means that the minimum filtration efficiency is more than or equal to 99 percent; the third is a grade of 100, which represents that the minimum filtration efficiency is more than or equal to 99.97 percent; such products are only effective at filtering aerosols or pathogens, as indicated by the industry mask product labels according to the U.S. NIOSH and eu standards.

The general design of ordinary gauze mask shape is planar, the molding is rectangular usually, there is three folded layer in the middle of the gauze mask, in using, it makes the laminating of gauze mask body at user's nose to expand the folded layer, oral cavity and face, mainly used separation oral cavity and nasal cavity expired splash, disposable health care under the general medical environment of being used for, the protection level is minimum, be applicable to general health care activity, such as sanitary cleanness, join in marriage liquid, clean bed unit etc. or the separation or the protection of granule such as pollen etc. outside the pathogenic microorganism, the nose that the line can not make gauze mask laminating uplift well is moulded to the nasal part of ordinary gauze mask simultaneously, cause to produce the clearance between gauze mask and the nasal part, reduce the protective effect of gauze mask, the gas of exhalation produces the fog through the clearance easily on the user's of glasses the lens.

The shape of the N95 type medical protective mask is generally designed into a foldable type or a cup type, the grade of filter material is N95, the requirement on the filtering effect of non-oily particles is more than or equal to 95%, the N95 type medical protective mask is provided with a nose clip or a plastic nose strip, the scalability of an ear band is obviously stronger than that of a common mask, the circumference of the N95 type medical protective mask can be ensured to be tightly attached to the positions of the nose, the face and the like of a user, the breathing gas completely passes through the mask surface of the mask, and the protection grade, the production cost and the design shape of the mask are all obviously different from those of the common mask.

Medical N95-grade mask belongs to the medical protective mask that the high-grade protective filter material grade is N95 type, when the doctor uses at the respiratory tract infectious disease of treatment hospital, need to dress and keep apart the clothing, wear behaviors such as mask, wear ear-hanging N95 mask for a long time, cause easily to the ear and draw pressure, cause the discomfort of ear, influence medical staff's work, and simultaneously, difficult adjustment when ear belt N95 type medical protective mask uses, so it is necessary to provide a new technical scheme.
