Simple wearable filtering positive-pressure ventilation device

Abstract

The invention relates to a simple wearable filtering positive-pressure ventilation device. The simple wearable filtering positive-pressure ventilation device is characterized in that the simple wearable filtering positive-pressure ventilation device mainly comprises a gas generating component, a filtering component, a positive pressure collecting component and a protective equipment interface component; the gas generating component comprises a shoe-shaped pedal type plastic air pump and a unidirectional air inlet / air outlet valve (hole); the filtering component comprises a 3M-level filtering fabric and an anti-deformation plastic negative pressure pipe; the positive pressure collecting component comprises a gas input valve (access hole), an elastic air bag, a filtering element, a positivepressure gas output element and a pressure sensitive element; the protective equipment interface component comprises a positive pressure output interface, and the positive pressure output interface can abut against a poison preventing mask, a protective head cover and a sealing protective garment; by means of the simple wearable filtering positive-pressure ventilation device, external air can be introduced into the air bag for storage through walking or stepping, and particulate matters and harmful gas in the air are blocked by the filtering element; three layers of dirt-preventing filtering fabrics are arranged in the air bag, the pressure of the air bag is kept by a pressure reducing valve, and the air bag is combined with protective equipment to supply breathing cleaning air.

Description

technical field [0001] The invention relates to labor protection articles, in particular to a simple and wearable filter positive pressure ventilation device. Background technique [0002] Occupational respirable dust and outbreaks of pathogenic microorganisms in medical research have long threatened the health of practitioners, and there is an urgent need for a safer and more reliable protective equipment to reduce risks. [0003] Common respiratory products are masks. The existing masks on the market are all self-priming masks, whose filtration coefficient, breathing resistance and air tightness cannot meet the needs of consumers, and masks are divided into many specifications according to the protection requirements. There are as many as dozens of types of protective to cold-proof masks, which often lead to consumers misusing and buying fake products, which are difficult to identify. [0004] As a higher level of protection, protective clothing is often used together wit...

The protection validity period of this kind of dust respirator will change due to the dust concentration, and it will only last for a few hours under high concentration dust. Zero, while pneumoconiosis is a long-term and chronic deposition process of inhaled dust in the lungs from quantitative to qualitative changes, which is difficult to detect in the early stage and can easily cause paralysis
