The present invention relates to a hood for oxygen respirator to remove the carbon dioxide contained in the hood of the hood when breathing wearing a hood to form a hood for oxygen respirator so that breathing is comfortable while wearing the hood.

As is well known, most of the accidents at the time of a fire are not ignited, but suffocated by toxic gases.

Statistics show that more than 60% of fire deaths are asphyxiated by gas and smoke, and only about 20% are burned.

Therefore, if a person exposed to oxygen deficiency or toxic asphyxiation due to a fire can receive fresh air (i.e. oxygen) for a long time away from this risk, the suffocation of human life due to asphyxiation will be greatly reduced. For this purpose, an emergency oxygen respirator (oxygen supply device) that can be used for personal purposes may be considered.

In order to be able to be used as an emergency (emergency oxygen respirator) capable of supplying oxygen in an emergency such as a fire, some desirable conditions are required as follows.

First of all, in order to be provided for emergency use by individuals, it is small and compact in order to be kept in an environment where there is a possibility of fire, such as various residential buildings including offices, offices, factories, public buildings, and various vehicles including electric cars and passenger cars. One is preferable. In other words, if the large size occupies a lot of space and affects the beauty of the surroundings, no matter how excellent the oxygen supply ability, people will be reluctant to use the oxygen respirator as a first-aid supply, practically low utility.

Second, there should be no leakage or breakdown of oxygen during long-term storage periods until unexpected emergencies occur and use, and it should be easy to operate even in emergency situations where the fugitive is embarrassed. This is because if it is stored for a long period of time, oxygen leaks, breaks down, or is difficult to operate, it can be useless in an emergency situation.

Third, in the event of an emergency such as a fire, it should be possible to supply and inhale a certain amount of oxygen uniformly during the time until evacuation to a safe place (eg within 5 minutes). In other words, it is limited to increase the size of the oxygen can for the compact size, and this causes a small amount of oxygen to be charged and thus insufficient oxygen supply or high pressure (eg, 200kgf / There should be no problems such as the release of large quantities of oxygen in cm 2) at the beginning and the supply below the amount needed for breathing.

In order to solve the above problems, the present inventor has been registered for the "emergency oxygen respirator" (application number: No. 20-2003-0031647).

However, the hood 71 used for the user's face in the hood 70 used in connection with the emergency oxygen respirator 1 and the tube 60 in the "emergency oxygen respirator" is located in the inner space according to the user's breathing. There was a drawback that the concentration of carbon dioxide is generated due to the user's breath is loaded.

That is, when the user breathes for 10 minutes or more while receiving oxygen from the emergency coral respirator 1 while wearing the hood 71, the concentration of carbon dioxide is loaded in the air of the hood inside the space by 10% or more. The headache was felt, and thus the user was unable to quickly and smoothly evacuate, causing a large accident.

The present invention is to solve the above disadvantages, to provide a coral respirator hood for the purpose of preventing the carbon dioxide generated during respiration is loaded into the hood of the hood to increase its concentration.

In order to achieve the above object, the present invention provides a hood for an oxygen respirator hood that is used by connecting with an emergency oxygen respirator and a tube; One end is fixed to the inside of the hood and has a shape having a shape through which air flows in and out, and further comprises a carbon dioxide adsorbent (not shown).

The reservoir has a cylindrical shape in which the lower surface is fused on the inner surface of the hood and the upper end is open, and a plurality of vents are formed in the cylinder, and a male thread part is formed at the outer periphery and the lower end is open in the cylindrical shape. A plurality of vents are formed, a female threaded portion for fastening is formed at the inner circumference, and a cover is formed at the center of the upper surface.

The vents formed in the case and the cover are formed to correspond to each other in a state in which the case is covered with a cover.

It is preferable to further include a silicon cover to protect the user's mouth on the outer periphery of the tube.

The reservoir is fixed to the inner surface of the hood so that the tip of the tube is located on the front side of the user's mouth while the hood is bitter.

Hereinafter, with reference to FIGS. 1,2,3,4 attached to the correct embodiment of the present invention will be described in detail.
