Description

Portable oxygen respirator

The present invention relates to a portable oxygen respirator. More specifically, by connecting a small-capacity oxygen tank to the decompression regulator, and implementing an oxygen respirator with a simple structure by connecting an air part and a mouthpiece or a mask to the decompression regulator to inhale it, it lowers the manufacturing cost and maximizes portability. In case of fire, it can be easily used by children or the elderly, and by forming a micro flow path in the decompression regulator to change the flow direction repeatedly to reduce the oxygen to a constant pressure so that an appropriate amount of oxygen can be continuously supplied. By forming an exhaust port in the air part, combining the discharge cover with the discharge port formed in the lower part of the exhaust port, and inserting a suction barrier film between the exhaust port and the discharge cover, the exhaust port is closed during inhalation, the outside contaminated air To prevent it from entering inside, and at the time of exhalation It relates to a portable oxygen respirator which is opened to allow exhalation to be discharged to the outside.

As an oxygen supply device, an oxygen cylinder of an oxygen inhaler used for emergency use in a hospital is typical, and an oxygen cylinder is provided in a workplace where dust or smoke is severe so that an operator can inhale fresh oxygen at any time.

However, such oxygen supply means is oxygen is accommodated in a large container is impossible for the individual to carry. Therefore, when a severe exercise or hiking, emergency breathing due to fire, etc. is required, especially in a dusty or smoke-rich workplace, such as a simple portable device that can inhale fresh air from time to time.

There are few portable oxygen masks that can be used in situations where toxic gases are generated, such as fires. Gas masks on subways are effective in chemical warfare, but they cannot solve the lack of oxygen that is the basis of asphyxiation. As they do not generate oxygen, they cannot be a solution to suffocation. In particular, if the toxic gas can be avoided between the first three to five minutes in the event of fire, it is possible to reduce the human injury caused by asphyxiation.

On the other hand, in the case of the oxygen mask has a very high pressure inside the oxygen cylinder containing the oxygen, there is a problem that the injection is very strong when oxygen is discharged is inappropriate for human inhalation and somewhat dangerous.

The present invention has been made to solve the above problems, in particular to lower the manufacturing cost and to maximize portability to facilitate the use of children or the elderly in the event of a fire, etc., and continue to supply an appropriate amount of oxygen The purpose of the present invention is to provide a portable oxygen respirator that prevents external polluted air from entering the air unit during inhalation and exhales to the outside during exhalation.

Portable oxygen respirator according to the present invention devised to achieve the above object has a pressure reducing regulator having at least one oxygen inlet on one side, the oxygen outlet on the other side; An oxygen cylinder accommodating oxygen therein and connected to the oxygen inlet; And an empty space therein, and including an air portion coupled to the oxygen outlet.

In addition, a microchannel may be formed inside the decompression regulator to be bent a plurality of times to reduce the pressure of oxygen by changing the flow direction of oxygen.

In addition, an exhaust port may be provided at one side of the air part, a discharge cover having a plurality of discharge ports may be coupled to an outer surface of the region where the exhaust port is formed, and a suction barrier layer may be inserted between the exhaust port and the discharge cover.

According to the present invention by connecting a small-capacity oxygen tank to the pressure reducing regulator, and by implementing an oxygen respirator with a simple structure by connecting the air portion and the mouthpiece or mask to the pressure reducing regulator to inhale this, to lower the manufacturing cost and maximize portability In the event of a fire, it is effective to make it easier for children or the elderly to use.

In addition, according to the present invention by forming a micro flow path in the pressure-reducing regulator repeatedly by changing the flow direction there is an effect that can be supplied to the appropriate oxygen continuously by reducing the pressure to a constant pressure.

In addition, according to the present invention, by forming an exhaust port in the air portion, engaging the discharge cover formed with the discharge port in the lower portion of the exhaust port, and inserting the suction barrier film between the exhaust port and the discharge cover, the exhaust port is closed during inhalation and the external pollution The air is prevented from entering the inside of the air portion, and during exhalation has an effect that the exhalation is opened to the outside to exhale.

The pressure reducing regulator 10 has at least one oxygen inlet 12 on one side and an oxygen outlet 14 on the other side. For example, FIG. 2 illustrates an example in which a pair of left and right oxygen inlets 12 are provided.

The pressure regulator 10 has a fine flow path formed therein. The micro-channel is bent a plurality of times to change the flow direction of oxygen serves to reduce the pressure of the oxygen discharged from the oxygen cylinder (30). The pressure reduction regulator 10 may be formed of a metal material, and the pressure reduction regulator 10 is not limited thereto.

The decompression regulator 10 depressurizes the oxygen discharged from the oxygen cylinder 30 in which the compressed oxygen is stored at a constant pressure so that appropriate oxygen can be continuously supplied for a predetermined time.

The coupling member 20 combines the oxygen cylinder 30 and the oxygen inlet 12 to maintain airtightness, thereby preventing the oxygen discharged from the oxygen cylinder 30 from leaking to the outside. The coupling member 20 may be formed of an elastic material such as silicon, but the material of the coupling member 20 is not limited thereto.

The oxygen cylinder 30 accommodates oxygen therein and is connected to the oxygen inlet 12 of the pressure reducing regulator 10.
