Description

Oxygen Inhaler for Emergency

(Technology)

The present invention relates to an emergency oxygen respirator, and more particularly, by supplying oxygen to inhale oxygen until a dangerous person, such as oxygen deficiency or toxic gas suffocation, arrives at a safe situation. It relates to an emergency oxygen respirator to prevent the.

(Background)

In the event of a fire, most of the accidents are caused by toxic gas, not by fire. 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 used as an emergency oxygen respirator (oxygen supply) capable of supplying oxygen in an emergency, some desirable conditions are required as follows.

First, in order to be able to use it for emergency use by individuals in various environments such as apartments, residential buildings, factories, public buildings such as subway stations, and various vehicles including electric cars and passenger cars, the size must be It is desirable to be small and compact. 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 a large amount of oxygen in the early stage (2 cm2) and the supply in the second half is less than the amount required for breathing.

The inventor proposed a utility model registration No. 338192 (registered Dec. 30, 2003) that satisfies the above conditions for oxygen supply in such an emergency, and the design of '192 is a screw type method. When the knob is turned, the oxygen can is drilled to release oxygen.

It is an object of the present invention to provide an emergency oxygen respirator, which allows a fugitive person to inhale a high concentration of oxygen while escaping from an emergency such as oxygen deficiency or toxic gas suffocation that may occur due to a fire or the like.

Another object of the present invention is to provide various types of residential buildings, factories, public buildings such as subway stations, and other vehicles including electric cars and passenger cars, so that the storage occupied area is not large and the size is compact so as not to damage the surrounding aesthetics. Yet, it is intended to provide an emergency oxygen respirator, which is convenient to operate and hardly causes leakage or breakdown of oxygen even during long term storage.

Another object of the present invention is to provide an oxygen respirator capable of uniformly supplying oxygen for a time sufficient to evacuate to a safe place in the event of an emergency.

Hereinafter, with reference to the accompanying drawings will be described in detail the emergency oxygen respirator according to the present invention. The following embodiments are merely illustrative of the emergency oxygen respirator of the present invention, it is not intended to limit the scope of the present invention.

1 to 4, the emergency oxygen respirator 1 according to the present invention basically includes a housing 10, a perforation part 20, an operation part 30 and an oxygen outlet 40. .

The housing 10 is a skeletal member of the oxygen respirator 1 of the present invention to which the oxygen can 2 filled with high pressure oxygen is mounted, and its appearance is not limited to the shape of FIG. 1.

The oxygen can mounting part 11 to which the oxygen can 2 is mounted is formed in the lower side of the housing 10. The oxygen can mounting unit 11 is not particularly limited as long as the oxygen can mounting unit 11 can be firmly and hermetically mounted in the high pressure environment.

In the illustrated embodiment, a hole in which the spout 2A of the oxygen can 2 is inserted is formed in the lower end of the housing 10, and the screw 11A and the oxygen can spout 2A of the oxygen can mounting portion 11 are formed. The structure in which the screw 2B is tightly fastened by screwing is illustrated, whereby the oxygen can 2 is firmly held in the oxygen can mounting part 11 even under a high pressure environment.

As the oxygen can 2 is detachably mounted to the housing 10 by screwing, the emergency oxygen respirator 1 according to the present invention can be used repeatedly by replacing the used oxygen can 2.

As the oxygen can 2 applied to the present invention, for example, a small can made of a high strength aluminum alloy (eg, AL6051) may be used to have a volume of about 200 cc in a size of about 220 mm in height and about 50 mm in diameter. . For example, the oxygen can 2 can be filled with 40 L of oxygen having a concentration of 95% or more at a pressure of 200 kgf / cm 2, and the seal 2C of the spout 2A can be a copper plate having a thickness of about 1 mm. The size of the oxygen can 2, the amount of oxygen to be filled, the pressure, and the like can be appropriately selected and adjusted according to the place of use of the oxygen respirator 1 of the present invention, the required amount of oxygen, its discharge duration, and the like.

Preferably, the housing 10 may be provided with a ring 12 through which the cord 13 may be hooked so that the oxygen respirator 1 may be hung around the neck.

The housing 10 is equipped with a perforation 20. The perforation section 20 is mounted to the housing 10 so as to be movable up and down, and preferably includes a perforation protrusion 21 that can perforate the seal 2C of the spout 2A of the oxygen can 2.

The perforation protrusion 21 is located adjacent to the spout 2A of the oxygen can 2 in the state where the oxygen can 2 is mounted on the oxygen can mounting portion 11, but in a general state (for example, the oxygen respirator of the present invention). In the unused storage state), the spout 2A of the oxygen can 2 is located in a place where the spout 2A of the oxygen can 2 is not perforated, and when the external force acts and descends, the spout 2A of the oxygen can 2 is perforated at that time.

Preferably, the perforation protrusion 21 may be provided with a vent 22 along the center thereof, and oxygen from the perforated oxygen can 2 passes through the vent 22. In the illustrated embodiment, the air passage 22 is connected to the oxygen outlet 40 via the decompression unit 50.

The operating unit 30 is mounted to the housing 10. The operation unit 30 is a member for operating the oxygen can 2 when the oxygen respirator 1 is intended to inhale oxygen. When the operation unit 30 is operated, the drilling unit 20 descends and drills. The projection 21 punctures the spout 2A of the oxygen can 2. The operating part 30 is mounted against the oxygen can 2, that is, the operating part 30 is mounted to face the oxygen can 2 with the perforation part 20 therebetween.

According to a feature of the present invention, the operating unit 30 is mounted to the housing 10 to be moved up and down, and thus, pressing the operating unit 30 by hand or pressing against a hard object, the operating unit 30 Press the perforated part 20 while descending, whereby the perforated part 20 is moved to the oxygen can 2 to perforate the oxygen can 2.

That is, the operation unit of the oxygen respirator of the above-mentioned utility model registration No. 338192 is screw type, so that the oxygen can is perforated by turning the handle, and the oxygen respirator 1 according to the present invention does not turn the operation unit 30, but immediately. It is a push type (or impact type) to press and punch.

In the illustrated embodiment, the actuating portion 30 acts with the pressing piece 31 protruding outward from the housing, the acting piece 32 for transmitting a force to the perforation 20, and the pressing piece 31. It includes a stem 33 connected between the pieces 32 and extending through the inside and outside of the housing 10. Reference numeral 34 denotes a cushioning for absorbing the shock when the operating portion 30 rises by the pressure of oxygen.

Thus, according to the organic configuration of the housing 10, the perforation 20 and the operation unit 30, by pressing the pressing piece 31 of the operation unit 30 by hand or by pressing against a hard place (for example, a wall) In addition, while the operation unit 30 descends, the punching unit 20 is lowered, whereby the punching protrusion 21 drills the spout 2A of the oxygen can 2.

Oxygen released from the spout 2A of the oxygen can 2 is discharged to the outside through the oxygen outlet 40 formed in the housing 10, the released oxygen is a hood 70 or a mask (as illustrated later) 80) and so on.

As the oxygen as it is discharged from the oxygen can 2 is irregular in accordance with the pressure state of the oxygen can 2, the oxygen is excessively discharged in excess of the amount necessary for breathing at the beginning of use, and breathing at the end of use. In short, oxygen may be released in small amounts.

In consideration of this point, the emergency oxygen respirator 1 according to the present invention may include a decompression unit 50 which uniformly decompresses the high pressure oxygen discharged from the oxygen can 2 to a pressure suitable for respiration. have. The pressure reduction part 50 can apply the well-known structure which can reduce the pressure by the said area ratio by passing oxygen from a relatively narrow area to a large area.

In the illustrated embodiment, the decompression unit 50 connects the oxygen inflow passage 51 and the orifice 51A, which are connected downstream of the air passage 22 of the punching protrusion 21 and have an orifice 51A formed at their ends. A valve 52 having a tapered portion 52A for selectively opening and closing, a first spring 53 for pressing the valve 52 toward the closing of the orifice 51A, and a cylinder extended space downstream of the orifice 51A ( 54, the piston 55 mounted so as to be movable in the cylinder 54 and in contact with the end of the valve 52, and the piston 55 so that the valve 52 is forced to move toward the opening of the orifice 51A. It shows an example made of a configuration including a second spring 56 for pressing ().

According to the structure of such a decompression part 50, the high pressure oxygen which flowed in from the oxygen can 2 into the oxygen inflow path 51 through the air flow passage 22 passes from the narrow orifice 51A to the wide cylinder 54. It is decompressed to a pressure suitable for inhalation as it passes.

The valve 52 of the pressure reduction part 50 is the oxygen of the cylinder 54 with respect to the sum of the pressure of the oxygen acting from the oxygen can 2 through the oxygen inflow path 51 and the elastic force of the first spring 53. Moves up and down in accordance with the equilibrium state of the pressure acting on the tapered portion 52A and the elastic force of the second spring 56 to keep the oxygen passing amount constant.

Therefore, the orifice 51A, the valve 52, the first spring 53, the cylinder 54, and the second spring of the oxygen inflow passage 51 are adapted to the oxygen respiration amount and discharge time required when evacuating from an emergency. By properly determining the specification of (56), it is possible to ensure that a certain amount of oxygen is uniformly supplied for a certain time.

Preferably, the decompression unit 50 may be formed to move up and down in conjunction with the perforation unit 20. That is, as described above, the perforation part 20 is a structure that moves up and down according to the operation of the operation part 30, and the arrangement of the pressure reducing part 50 is designed regardless of the vertical movement of the perforation part 20. It may not be desirable to compact the housing 10.

For this reason, in the illustrated embodiment, the perforated part 20 and the decompression part 50 are structurally positioned in one block so that the decompression part 50 also interlocks up and down together in the shanghai-dong of the perforated part 20. will be. Connection of the decompression unit 50 and the oxygen outlet 40 may use a flexible pipe 41 to accommodate the vertical movement of the decompression unit 50.

As shown in FIG. 3, when the oxygen can 2 is perforated, high pressure oxygen is released to exert pressure on the perforation part 20, so that the perforation part 20 and the operation part 30 are naturally pushed upward. It will be in its original position when not pressed. After the oxygen can 2 has been drilled, the up and down positions of the perforations 20 do not affect the operation of the oxygen respirator 1, but the pressure reducing unit 50 and the oxygen outlet 40 are connected to the pipe 41. It is preferable that the outlet 57 of the decompression unit 50 and the oxygen discharge port 40 are at the same level in the state where the perforated part 20 is pushed up so that the connection is structurally stable. Reference numeral 58 denotes sealings that prevent oxygen from leaking out if there is oxygen leaking out through the vent 22.

Oxygen discharged from the oxygen can 2 is discharged out of the housing 10 through the oxygen discharge port 40. In particular, the oxygen passing through the decompression unit 50 is discharged to the outside through the oxygen outlet 40 after being decompressed to a pressure suitable for inhalation, and the user inhales the oxygen exiting through the oxygen outlet 40.

The oxygen outlet 40 is equipped with equipment for conveniently and easily supplying oxygen to the user in an emergency. As such equipment, the tube 60 and the hood 70 can be preferably used.

The tube 60 is connected to the oxygen outlet 40, and is made of, for example, a flame retardant flexible material. The length of the tube 60 is of sufficient length (eg, about 1M) to allow the user to wear or hold the housing 10 while wearing the hood 70.

Preferably, the hood is formed of a breathable flame-retardant flexible material to be worn on the face 71, a transparent viewing window 72 formed on the hood 71 to see the outside, the hood 71 And a one way valve (73) formed in the hood (71) to block the air inflow from the outside to the hood (71) but the air is discharged from the hood (71). It can be configured to include a tube connector (74) to which the tube 60 is connected, and a drawstring (75, or elastic cord) to eliminate the gap between the hood (71) and the human body. Preferably the see-through window 72 is anti-fog. The hood 71 may be made of, for example, a flame retardant urethane having a size of about 460 mm × 550 mm and a thickness of 0.24 mm.

According to the application of the hood 70 as described above is discharged to the oxygen can (2) and oxygen through the housing 10 is supplied into the hood 71 through the tube 60, so that the user emergency situation such as fire At high concentrations of oxygen can be supplied for a period of time without exposure to toxic gases.

In the illustrated embodiment, an example in which the tube 60 and the hood 70 are connected to the oxygen outlet 40 is illustrated, but it is obvious that the mask 80 may also be connected.

In the above, the oxygen respirator 1 of the present invention has been mainly described in the case of using an emergency in which toxic gas is released, such as a fire. It can be used naturally as well.

The emergency oxygen respirator 1 according to the present invention described above is exposed to toxic gas by uniformly supplying high concentrations of oxygen during the time until the fugitive becomes a safe state in the event of various oxygen deficiency emergencies such as a fire or By not allowing oxygen deficiency, various types of residential buildings, factories, public buildings such as subway stations, and various vehicles including electric cars and passenger cars can be used for emergency purposes, and the number of life loss due to lack of oxygen is greatly reduced. It is expected to be widely useful as a life preserver.

In addition, the oxygen respirator of the present invention is compact in size and easy to store in residential buildings, offices, factories, public buildings, vehicles, etc., and it is convenient to operate and there is little fear of oxygen leakage or breakdown during storage. It also works.

In particular, since the oxygen respirator 1 according to the present invention is a push type (impact type) in which the oxygen can is perforated when the operating part is pressed by hand or hitting the wall, the oxygen respirator 1 can be operated very easily in an emergency situation in which the danger of being confused is difficult. It can be effective.
