Protective device for allergic rhinitis patient

Abstract

The invention discloses a protective device for the allergic rhinitis patient. The protective device comprises a protective nasal mask, wherein the protective nasal mask comprises a plastic shell, installation rings installed on the two sides of the plastic shell, bandages fixedly connected to the installation rings and non-woven fabric arranged on the rear side of the plastic shell, and the non-woven fabric is matched with the plastic shell; the non-woven fabric is composed of a dry breathable layer, a water absorption layer and an anti-allergic layer, the water absorption layer is located between the dry breathable layer and the anti-allergic layer, an installation pipe is embedded in the front side of the plastic shell, and a detachable multi-stage filtering and heating mechanism is arranged in the installation pipe. The protective device is advantaged in that the protective device is reasonable in design, the risk that gas particles and harmful gas are inhaled by people is reduced through multiple times of filtering and adsorption, inhaled gas can be heated in cold weather, the breathing comfort degree is improved, non-woven fabric can be rapidly taken down to be replaced, the attaching performance in the wearing process can be improved through the arrangement of the springs, and the mask is convenient to use and high in practicability; The protective device is convenient for people to use.

Description

technical field [0001] The invention relates to the technical field of protective devices, in particular to a protective device for patients with allergic rhinitis. Background technique [0002] Nasal mask generally refers to a device worn on the nose to filter the air in and out of the nostrils, so as to block harmful gases, odors, and droplets from entering and exiting the wearer's mouth and nose. Patients with allergic rhinitis usually wear a nasal mask when going out to prevent dust from entering the nostrils and causing discomfort to personnel; [0003] Most of the existing nasal masks are used to block dust particles in the air by making multiple layers of protective cloth. The filtering and blocking effect is relatively poor, and it usually does not have a good effect on tiny particles and harmful gases such as smog. Blocking effect, does not have the function of heating the inhaled gas. In cold weather, the gas is mostly cold. Patients with rhinitis who directly bre...
