Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an RFID evacuation induction attenuator which can be used for a long time,

The present invention relates to an RFID evacuation guiding respirator that can be used for a long time. More particularly, the present invention relates to an RFID evacuation guiding respirator that can remove a portion of carbon dioxide from a user's exhalation by using soda lime, .

In general, gas masks are used to protect the human body from toxic gases and harmful substances and are usually used by soldiers, police, and workers working in harmful environments.

In addition, the gas mask is provided in various places such as subways, high-rise apartments, large buildings, hotels, etc. for easy use by the public. At this time, the gas mask to be used by the general public is worn only during the time of evacuation in case of fire or in case of emergency, so that it is manufactured differently from the gas masks for soldiers, police, and workers working in harmful environments.

The simplified gas mask is divided into three parts: an oxygen supply part for storing a predetermined amount of oxygen, a suction part for preventing the toxic gas and harmful substances from entering the user's nose and mouth, And a lens unit connected to an upper portion of the suction unit to protect the eyes from toxic gases and harmful substances.

However, this conventional simplified gas mask has a problem in that the user sucks a large amount of oxygen at a time at the time of first use and thus the oxygen supply portion is collapsed and the respiration is obstructed.

In addition, the user exhales carbon dioxide through the suction unit. After that, the user breathed through the oxygen supply unit where only carbon dioxide and a small amount of oxygen are present, which makes it difficult to effectively breathe.

In addition, since it is difficult to obtain a visual field due to smoke and power failure occurring in a fire or in case of emergency, there is only a lens part for protecting the user's eyes. Thus, it is urgent to provide an additional method for increasing the survival rate of the user.

For example, Korean Utility Model Registration No. 20-0261803 discloses a simple respiratory mask, which is a synthetic resin respiratory hood which can completely cover the head and neck, and the inner and outer surfaces of the respiratory mask hood communicate with each other at positions corresponding to oral heights And a neck locking band for binding the hood of the respiratory mask at a position corresponding to the throat. The neck hood of the present invention is characterized by comprising:

However, the present invention has a problem in that the locking band for fixing the hood may be a method of tightening the neck, which may cause a problem of the user's breathing, and a configuration for securing the view is not provided.

In addition, even if the lens unit is formed in the invention, there is a problem that it is difficult to mount the lens unit on the user's eyes because it is shaken by the wind around the periphery of the gas mask, which is a synthetic resin material, which is not fixed.

1 is a perspective view of an RFID evacuation-inducing respirator that can be used for a long time according to an embodiment of the present invention.

As shown in FIG. 1, the present invention can be used for protecting a human body from toxic gases and harmful substances by being worn in a fire or in the case of a subway, a high-rise apartment, a large building and a hotel, RFID evacuation guided respirator.

The RFID evacuation-inducing respirator 100 according to the present invention is composed of three parts: a face part 110, a circulation part 120, and an oxygen supply part 130. The RFID evacuation masquerade 100, which can be used for a long time, can remove some carbon dioxide from the user's exhalation by using soda lime and recycle it to the user's breath.

The face portion 110 includes a lens portion 111 for protecting the user's eyes, a band portion 112 extending to both sides of the lens portion 111 and fixed to the back of the user, A speaker unit 113 having a member 113a therein and a purifier 114 positioned at the lower end of the lens unit 111 when worn to prevent toxic gases and harmful substances from entering the nose and mouth .

The band portion 112 may be securely fixed to the back of the user so that the band portion 112 can be sized to fit around the user's head after fastening so that the band portion 112 is not shaky.

The communication member 113a guides a user to an exit through a signal, and the rescue team grasps the location and the situation of the user so that an RFID (Radio Frequency Identification), an Ultra High Frequency (UHF) Communication) or USN (Ubiquitous Sensor Network).

The circulation unit 120 includes a carbon filter 121 coupled to a lower end of the purifying unit 114 to allow oxygen to be sucked by the user through the carbon filter 121, A filter 122 and an oxygen pouch 123 in which oxygen is circulated in combination with the carbon filter 121 and the soda filter 122.

The carbon filter 121 and the soda filter 122 are detachably connected to the oxygen pouch 123 to separate the oxygen pouch 123 when oxygen in the plurality of oxygen pipes 131 to be described later is exhausted. And the purifying function of the carbon filter 121 itself can be utilized.

At this time, the carbon filter 121 refers to an aggregate of amorphous carbons activated by a substance containing carbon or carbon, which has a large internal surface area and is very strong in adsorption force. The carbon filter 121 can be used in air purification, purification, and wastewater treatment devices for the purpose of removing taste, odor, and color, or in the chemical and pharmaceutical industries such as purification of raw materials and gas removal.

The soda filter 122 is a filter containing soda lime, which is a white granular solid made by heating a quick lime immersed in a concentrated solution of sodium hydroxide, and is used as an absorber of carbon dioxide, an organic synthesis, and an absorber of water. It can absorb and remove some carbon dioxide from exhalation.

Silica gel 123a may be contained in the oxygen pouch 123 to remove moisture present in oxygen through which the carbon dioxide has been removed through the soda filter 122.

The silica gel (123a) is a silicate particle of a sturdy net structure formed by the reaction of sulfuric acid and sodium silicate, and is used as a desiccant because it has a very large surface area and is excellent in the ability to absorb water, alcohol, 122 may remove moisture that is present in the oxygen absorbed by some of the carbon dioxide.

The oxygen supply unit 130 is configured to store oxygen that is mixed with a preliminary oxygen cylinder 131a in which oxygen consumed during the initial breathing is stored and oxygen that is partially removed from the carbon dioxide gas through the soda filter 122 after the initial breathing A plurality of oxygen cylinders 131 including the compressed oxygen cylinders 132b and a valve 132 connecting the plurality of oxygen cylinders 131 and the oxygen pockets 123.

Since the precious oxygen cylinder 131a sucks a larger amount of oxygen when the user wears the gas mask and sucks the first oxygen, the spare oxygen used at the first breathing is stored separately from the oxygen used after the first breathing .

The RFID evacuation masquerade, which can be used for a long time according to the present invention, can remove some carbon dioxide from the user's exhalation by using soda lime and can recycle the user's breath.

Also, according to the present invention, a long-time use RFID evacuation-guiding respirator for use in the present invention includes a speaker that emits a beep by using an RFID system to guide a user to an exit, and a rescue team recognizes a user's position and situation through a USN system, .

In the following, the required compressed oxygen amount is calculated by limiting the weight to 80 kg, the time required for 20 minutes, and the energy required per day to 2500 kcal / day.

The energy required for 20 minutes is given by Equation 1 below.

When the fat is assumed to be 9 kcal / g, the required fat mass is given by the following equation (2).

Fat is composed of (CH₂) n, and CH ₂ = 14 g / mole, the required fat content is given by the following equation (3).

Oxidation of 0.28 moles of fat requires 1.5 times the oxygen.

Finally, the required oxygen amount is given by the following equations (4) to (5).

Volume of 1 mole of oxygen = 22.4 L,

FIGS. 2A and 2B are illustrations showing the use of the RFID evacuation-inducing respirator of FIG. 1 which can be used for a long time. Hereinafter, an RFID evacuation-inducing respirator that can be used for a long time will be described with reference to FIGS. 2A and 2B.

The band part 112 is fixed to the back of the user in the event of a fire or a fire in the first subway, a high-rise apartment, a large building, a hotel or the like, so that the gasket 100 is prevented from entering the eyes, nose, mouth, The preliminary oxygen stored in the preliminary oxygen cylinder 131a is sucked through the carbon filter 121 after the valve 132 is opened.

At this time, a strap (not shown) capable of being detachably attached to the user's neck may be formed at the top of the oxygen pocket 123 so that the respiratory mask 100 can be stably mounted to the user. In addition, the oxygen bag 123 may be formed of a flame retardant material so as not to burn easily in the event of a fire.

The carbon dioxide contained in the user's exhalation is partially removed while passing through the soda filter 122 and is dehumidified by the silica gel 123a of the oxygen bag 123 and mixed with the compressed oxygen stored in the compressed oxygen cylinder 131b, And can be sucked to the user through the filter 121.

FIGS. 3A and 3B are usage diagrams showing another embodiment of the RFID evacuation-inducing respirator that can be used for a long time in FIG. Hereinafter, another embodiment of an RFID evacuation-inducing respirator that can be used for a long time will be described with reference to FIGS. 3A and 3B.

When the compressed oxygen is exhausted by using all of the compressed oxygen stored in the compressed oxygen cylinder 131b by wearing the gas mask 100 in the event of a fire such as a subway, a high-rise apartment, a large building and a hotel, 122 and the oxygen bag 123 connected thereto.

Accordingly, the purifying function of the carbon filter 121 itself can purify the outside gas, and the purified oxygen can be sucked.
