Description

[Detailed Description of the Invention] [Technical Field] This invention is applicable to emergency medical treatment for accidents such as fire, oxygen deficiency, generation of harmful gases, difficulty in breathing due to illness, etc.
The present invention relates to an oxygen generator used for respiratory support after sports.

[Background technology]

BACKGROUND OF THE INVENTION Conventionally, cylinders filled with oxygen have been generally used for emergency medical treatment for accidents such as fire, oxygen deficiency, generation of harmful gases, difficulty in breathing due to illness, and for respiratory support after sports. However, this is large, not easy to use, and expensive. For this reason, an oxygen generator that can be easily used is desired.

A device that meets this requirement is disclosed in Japanese Unexamined Patent Publication No. 54-93896. This method generates oxygen using a chlorate mixture, and has the advantage of being easier to use than the method using an oxygen cylinder. However, in this oxygen generating device, it is necessary to remove impurities such as harmful chlorine gas, and in order to ensure the safety of the device, the device becomes complicated and expensive.

On the other hand, JP-A-54-26990 discloses sodium peroxycarbonate (NazCO, 3/2uz.

It has been shown that oxygen can be generated by bringing 2) into contact with a suspension or aqueous solution of a catalyst. This method has the characteristics of being much easier to use than the above-mentioned oxygen cylinders and chlorate mixtures, as well as being safe, reliable, and inexpensive. However, if the alkaline aqueous solution comes into direct contact with the skin or enters the eyes, it may cause irritation or irritation, and disposal of the alkaline aqueous solution becomes a problem when the container is discarded after use. There is.

[Purpose of the invention]

This invention has been made in view of the above problems, and aims to provide an oxygen generator that can easily process an aqueous solution after oxygen generation [Disclosure of the Invention] To achieve the above objects. This invention contains water, a drug that generates oxygen when it comes into contact with the water, and a water-absorbing polymer compound that absorbs the aqueous solution after oxygen generation and becomes gel-like. The gist of the oxygen generator is an oxygen generating device in which at least water among the above components is separated and built in so that it does not come into contact with other components.

Hereinafter, one embodiment of the present invention will be explained based on FIGS. 1 to 4.

As shown in FIG. 1, water 3 containing an aromatic agent is stored in a first container 2, which is the bottom of a container 1 made of a material such as polypropylene or polyethylene.

Although an aromatic agent is not necessarily necessary for this invention, if the water 3 is scented with this aromatic agent, the user's mood can be eased. The method of adding the fragrance is not particularly limited, but for example, a method of impregnating urethane foam with a fragrance and making it solid is placed in water 3, or a method of dissolving the fragrance in a hydrophilic solvent such as alcohol. , and mixing this with water 3, or other commonly used methods can be used. By the method described above, it is possible to add aromas to the water 3 according to the purpose, such as citrus, menthol, or forest scents.

A catalyst 4, which is a chemical that generates oxygen, is located above the storage part 2.
and peroxycarbonate 5, and a water-absorbing polymer compound 6 that becomes gel-like by absorbing the aqueous solution after oxygen generation,
They are housed separately in respective housing parts 7 and 8 that are provided in the container 1 by welding or gluing.

In this example, as shown in FIG. It may be accommodated in the accommodating section 7, or may be further accommodated in a dedicated accommodating section provided separately. In short, when unused, this water-absorbing polymer compound 6
or the drug peroxycarbonate 5 or the catalyst 4
It is sufficient that the water is housed so that it does not come into contact with the water 3. Furthermore, in this embodiment, a case is shown in which the agent that generates oxygen upon contact with water 3 is composed of two components, the above-mentioned peroxy carbonate 5 and catalyst 4, but in the oxygen generating device of this invention, This drug may be one component or may be composed of three or more components as long as it generates oxygen when it comes into contact with water 3, and the number of drug storage compartments will be adjusted accordingly. That's all you need.

The peroxycarbonate used in this example is a compound having the general formula Mz Cz Oh, which decomposes to generate carbonate and oxygen when brought into contact with water in the presence of a catalyst. It is. Representative examples include sodium peroxycarbonate and potassium peroxycarbonate. Furthermore, examples of catalysts having the above-mentioned properties include manganese dioxide, the following metals, and compounds thereof, but the catalysts that can be used in the present invention are not limited to these.

iron, copper, nickel, cobalt, manganese, chromium, lead,
Vanadium, tungsten and their compounds.

The above metals or their compounds are encapsulated in a water-soluble polymer compound that gradually disintegrates and used as a catalyst. The reason why the catalyst is wrapped in a water-soluble polymer compound is to gradually bring the catalyst into contact with the peroxycarbonate and cause the reaction to occur.By doing this, oxygen can be generated for a certain period of time. This is because it can be done. Therefore, when a large amount of oxygen is suddenly required, it may be used without being wrapped in a water-soluble polymer compound.

Partition walls 9 and 10 are provided between each storage part 2 and 7.8, and when not in use, each component 4 and 5.6 is separated by these partition walls 9 and lO as shown in FIG. It is separated and built in so as not to come into contact with at least the water 3.

The partition walls 9 and 10 are made of a material such as aluminum foil or a double-layer material of PET film and aluminum, and can be broken through by pushing down the bar-shaped opening means 11 provided at the top of the container 1. It has become.

When the partition walls 9 and 10 are pierced by the opening means 11, as shown in FIG. The peroxycarbonate and the catalyst contact the water to initiate a reaction that generates oxygen. The oxygen generated by the reaction is transferred to the storage section 7, which is now a single space.
, 8, and is led out of the container 1 through a filter 12 provided at the top of the container 1 in connection with an opening means 11. This filter 12 is used to remove the mist produced when oxygen is generated and to prevent the contents from coming out when the container is tipped over.

In this embodiment, a mask 13 is provided at the top of the container 1 so as to be openable and closable, although this is not necessarily required for the present invention. When the mask 13 is not in use, it is folded up to serve as a lid for the filter 12, and when in use, it is opened to introduce oxygen to the user. The user first removes the film 1a covering the container 1 and the mask 13, as shown in FIG. Next, after opening this mask 13 and pushing down the filter 12 and generating oxygen as described above by the opening means 11 connected to this filter 12, as shown in FIG.
Put the mask 13 on your face and inhale oxygen. In addition,
In the figure, reference numeral 14 indicates a vent hole for supplementing the insufficient intake air with generated oxygen alone, and reference numeral 15 indicates a notch to prevent the user's nose from touching it.

The water-absorbing polymer compound 6, which is added to the water 3 together with the peroxycarbonate 5, which is an oxygen-generating agent, and the catalyst 4 absorbs almost no water when it is initially added to the water 3 (3 to 5 minutes after being added). Instead, gradually increase the amount of water absorbed over time (approximately 10% after 10 to 20 minutes), and at the stage when the reaction has finished and the generation of oxygen has stopped (30 to 4 minutes after adding water).
It is preferable that almost the entire amount of the aqueous solution after reaction be absorbed and gelled within 0 minutes). This is because if gelation is completed immediately after oxygen generation starts, sufficient oxygen generation will not be possible. Examples of water-absorbing compounds having the property of gradually absorbing water include, but are not limited to, the following compounds.

Starch polyacrylate, isobutylene-maleic anhydride copolymer, etc.

Such a compound is used in the oxygen generator of the present invention in the form of a spherical powder or a pellet of thermoplastic elastomer.

In this embodiment, only the structure shown in FIG. 1 has been described, but the structure of the oxygen generator of the present invention is not limited to this. That is, in this example, the storage portions for each component were provided adjacent to each other with one partition wall interposed therebetween, but they may be provided independently at completely separate locations within the container. In that case, each component may be mixed by a method other than the opening means. Further, the water-absorbing polymer compound does not need to be added to the water at the same time as the peroxycarbonate drug and the catalyst, and may be mixed with the water after the generation of oxygen is completed. In this case, the water-absorbing polymer compound does not need to be of a type that gradually increases its water absorption (although it may be of a type that rapidly absorbs water and turns into a gel).

As described above, in the oxygen generating device of the present invention, the aqueous solution becomes completely gel-like after oxygen generation is completed;
After that, even if the entire container is disposed of, this aqueous solution will not leak out of the container during processing such as incineration or landfilling, and for example, as in this example, the aqueous solution after the reaction will become alkaline. Even if it is harmful, it can be easily disposed of.

〔Effect of the invention〕

The oxygen generator of the present invention is configured as described above, and the aqueous solution after oxygen generation is absorbed by the water-absorbing polymer compound and becomes gel-like, so it can be easily disposed of. ing.
