Rescue breathing device

Abstract

The present invention relates to a rescue breathing device which can be kept in mouth for breathing during the process of rescue for a fire and so on and has a simple structure. The rescue breathing device comprises: a container (2) having the size that can be held by one hand; a plurality of filter materials (10) (11) (13) (14) filled in the container (2) and an air suction valve (16) arranged therein; an air suction port (9) formed at a lower part of the container (2); a shield (17) combined with an upper part of the container (2); a mouth piece (4) arranged at one side of the shield (17); an air exchange room (33) formed inside the shield (17); an exhaust valve (26) formed at the other side of an upper part of the shield (17); a case (6) for performing separation and combination at the upper part of the container (2); and a cover (7) for performing separation and combination at the lower part of the container (2), therefore, the rescue breathing device has the effects that the rescue breathing device can be kept in mouth for breathing during the process of rescue for a fire and so on to minimize casualties, and a whistle can automatically respond during the process of breathing to diffuse a distress signal around.

Description

technical field [0001] The present invention relates to an escape respirator with a simple structure that can be contained in the mouth and breathed during emergency rescue such as a fire. Background technique [0002] In general, large and small fires or disasters occur every year, resulting in a large number of fatal accidents. In particular, fires generate extremely high temperatures and pitch-black toxic gases that burn all surrounding objects, and spread and permeate the surroundings instantly. [0003] The types of burns and deaths caused by fire include death caused by physical injury, death caused by external burns, death caused by inhalation and burns, etc., and death caused by inhalation and burns, that is, death caused by inhalation of the temperature at the place where the fire occurs The high-temperature toxic gas produced at 250°C to 1100°C can cause respiratory tract burns and damage to internal organs, and most of them will cause death, which is the most fata...

Problems solved by technology

However, in the past, gas masks or dust masks have the characteristics of covering the entire head, the entire face, and the entire mouth to isolate the external air, which makes the volume and weight of the product larger. Therefore, in various fires or biological and chemical weapons warfare, In emergency disasters such as wartime, there are problems such as being inconvenient to carry and not being able to put on quickly. Therefore, it has the following problems: it is impossible to breathe safely even if it temporarily inhales hot smoke, fire, poisonous gas, etc. Evacuate to safety

[0005] In addition, although conventional gas masks have good anti-virus performance, they have the following disadvantages: difficulty in breathing, chest tightness due to covering the entire head, poor wearing experience due to sweat and moisture, and high price, bulky and heavy, etc.

[0006] In addition, although the conventional dust mask is easy to breathe, it has the following disadvantages: it is made of a single cloth or pad, so the dustproof effect is extremely poor, and it cannot isolate toxic gas in a fire or poisonous place

[0008] In addition, even if there is a gas mask, it is difficult to wear it for children, women, the elderly, those with special facial features, long hair, etc., because it has not been developed to make it convenient for the elderly and patients with poor respiratory organs. Products that are worn and can protect or treat the respiratory organs at ordinary times have various problems such as being difficult to find urban life full of pollution and pollutants
