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, in JP-A-54-26990, sodium peroxycarbonate (NazCOs・3/2H202
) and a suspension or aqueous solution of the catalyst have been shown to generate oxygen. This method, compared to the oxygen cylinder and chlorate mixture mentioned above,
It is much easier to use, is safer and more reliable, and is inexpensive.

For this reason, there is a demand for an oxygen generating device that is inexpensive and simple in structure and operation, using the peroxycarbonate, a safe chemical such as a catalyst, and water. However, since the above chemicals are hygroscopic, they may become unusable if stored for a long time, and if the entire oxygen generator is thrown away after each use, no matter how cheap it is, , there will be a lot of wasted parts.

[Purpose of the invention]

This invention was made in view of the above problems, and the purpose is to provide an oxygen generator that is inexpensive, simple in operation and structure, and can be used any number of times over a long period of time. [Disclosure of the Invention] In order to achieve the above object, a container containing water,
A cartridge having a drug accommodating portion in which a drug that reacts with water to generate oxygen is housed is replaceably connected, and the drug accommodating portion of the cartridge is formed to face the inside of the container in which the water is accommodated. The oxygen generator is provided with an opening means for breaking the partition wall, and a sealing means is provided at the connection between the container and the cartridge.

Hereinafter, one embodiment of the present invention will be explained in detail based on the accompanying drawings. In the examples below, a two-component agent consisting of peroxycarbonate and a catalyst is used as a chemical that reacts with water to generate oxygen, but it is also possible to use a chemical with component (1) or one with three or more components. is also possible.

First, the embodiments shown in FIGS. 1(a) and 2(b) and FIG. 2 will be described.

The container 1 is made by blow molding or the like using a material such as polypropylene or polyethylene, and water 3 is accommodated in the container interior space 2 . container 1
has a cylindrical shape with an opening at the upper end, and a cap 4 is connected and fixed by screws 5 so as to cover the opening. On the other hand, the cartridge 6 formed in a cylindrical shape
is provided with a flange 7 directed outward at its upper end, and this flange 7 is sandwiched between the opening periphery 8 of the container and the cap 4, thereby connecting the cartridge 6 and the container 1. ing. A gasket 9, which is a sealing means, is provided at this connection part in order to prevent oxygen from leaking from this part.

Inside the cartridge 6 formed by injection molding or the like, there is a first space 11 containing an oxygen generating agent IO made of peroxycarbonate that reacts with the water 3 to generate oxygen, and at the center thereof, A cylindrical body 13 is provided as a guide for an operating rod 12 serving as an opening means, into which the operating rod 12 is inserted. On the other hand, a hole 14 is provided at one end of the cartridge 6, and a film 15 serving as a partition is pasted to cover the hole. Inside this film 15, a cap-shaped partition member 16 is locked by a locking means 17 consisting of a protrusion and a groove in such a way that the central protrusion 16a is inserted into the cylindrical body 13. The space between the film 15 and the partition member 16 is a second space 1 in which the catalyst 18 is accommodated.
It is 9. Although the material of the film 15 is not particularly limited, preferred films for this invention include polyethylene terephthalate polyethylene, aluminum foil, and laminates thereof.

There are no particular limitations on the method of filling the cartridge with the oxygen generating agent or the catalyst as in the illustrated embodiment, but the cartridge can be easily filled with the chemicals by using the following process. That is, first, the filter holder 21 to which the filter 20 is welded is welded to one end of the cartridge 6. Next, the cartridge 6 is turned upside down, and after filling the oxygen generating agent 1o through the hole 14, the restriction member 16 is pushed in until it is locked by the locking member 17. After that, the catalyst 8 is filled here, and the film 15 is attached to the hole 14 by heat welding, thereby completing the filling of the drug.

When using the oxygen generator of this example, first,
The mask 22, which also serves as a cap, is removed and the upper end of the operating rod 12 is pushed into the container. Then, the operating rod 12 pushes out the partition member 16 toward the hole. The extruded cutting member 16 first touches the hole 1 with its blade-shaped tip 16b.
The film 15 attached to the container 4 is pushed out and the second space 19 and the container inner space 2 are communicated with each other. Therefore,
Catalyst 18 falls into water 3. When the diaphragm member 16 is further pushed out, it falls off from the cartridge 6, so the first space 11 and the container interior space 2 are communicated, and the oxygen generating agent 10 falls into the water 3, starting a reaction. oxygen is generated.

The peroxycarbonate used in this example is a compound with the general formula M z Cz Oh, which decomposes to generate carbonate and oxygen when brought into contact with water in the presence of a catalyst. It is something. 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.

t, i, nickel, cobalt, manganese, chromium 1 lead, vanadium, tungsten and their compounds.

The above metals or their compounds are used as catalysts by enveloping them in a water-soluble polymer compound that gradually disintegrates in water. 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.

After pushing in the operating rod 12 completely, attach the mask 22 that was previously removed on top of it in the opposite direction as shown in FIG. Place your face on the oxygen generated by the reaction, as shown by the arrows in the figure.

4 is a vent hole to compensate for the lack of intake air from generated oxygen alone, 25 is a notch to prevent the user's nose from touching it, 1
Reference numeral 2a denotes an operating rod locking ring that prevents the operating rod from falling out or getting stuck.

As described above, in this embodiment, by simply removing the cap 4, the cartridge 6 containing at least the oxygen generating agent 10 and the catalyst 18 can be easily replaced.

Therefore, if you prepare a large number of these cartrinshiro,
When the drug becomes useless after not using it for a long time, or when
Even after multiple uses, the other parts (e.g., container 1, cap 4, operating rod 12, mask 22, etc.) can be used again by simply replacing the cartridge 6 and discarding the used liquid. become. For this reason, for example, a picture or a pattern as shown in FIG. 2 can be drawn on the surface of the container 1. Further, in this embodiment, the operating rod 12, the mask 22° discharge port 23, etc. can be removed together with the cap 4, so these parts can be used again.

Next, another embodiment is shown in FIGS. 3(a) and 3(b).

In the illustrated embodiment, the connection between the container 1 and the cartridge 6,
The internal structure of the cartridge 6 is different from the previous embodiment. First, the connection between the container and the cartridge will be explained.

As shown in the figure, the container 1 is formed into a cylindrical shape with an opening provided at its upper end and a tapered portion. The cartridge 6 has a knockout part 2, which is a partition, on the bottom surface of the cartridge 6.

The cylindrical portion 27 is extended. Then, this cylindrical portion 27 and the opening peripheral edge 8 of the container are fitted, and the connection is fixed by the attractive force of a magnet 28 provided at this portion,
It can be easily removed.

This connection portion is also provided with a seal 9, which is a sealing means, as in the previous embodiment.

The inside of the cartridge 6 is a first space 11 that accommodates the oxygen generating agent 10, and in the center thereof, a cylindrical body 13 that is a guide for an operating rod 12 that is an opening means is connected to a knockout part 26 that is a partition wall. It is provided so as to face the user, and the operating member 12' is inserted therein.

This embodiment differs from the previous embodiment in that when the operating rod 12' is pushed, its tip directly pierces the knockout portion 2G. The operating rod 12' has a cylindrical shape with an opening at one end facing the knockout portion 26, and a second space 19 is formed inside the operating rod 12'. An isolation film 29 is attached to one end of the cylindrical body 13 on the side opposite to the knockout part 26 so as to cover the opening thereof, and the second space 1 in the operating rod 12' is closed.

When using the oxygen generator of this example, first,
To prevent the operating bar 12' from being pushed inadvertently, the stopper 12b is removed, and the operating bar 12' is pushed into the container. Pushed-in operating rod 12'
first breaks through the isolation film 29 attached to one end of the cylindrical body 13, and then breaks through the knockout portion 26. When the isolation film 29 and the knockout part 26 are pierced, the container inner space 2 and the first. The second space 11.19 is communicated with each other, the oxygen generating agent 10 and the catalyst 18 fall into the water 3, a reaction is started, and oxygen is generated. After this, as shown in FIG. 3(b), if you put your face on the mask 22 fixed to the upper end of the cartridge 6,
Oxygen can be inhaled. Note that the arrows in the figure are the same as in FIG. 1(b) (indicating the flow of oxygen).

In the above embodiment, the container 1 and the cartridge 6 were connected and fixed by the attraction force of the magnet 29.
As in the previous embodiment, the connection may be fixed by screwing. The partition wall may also be made of a hole and a film covering the hole, instead of the knockout portion 26, as in the previous embodiment. Further, in this embodiment, the mask 22 has a shape in which a cylindrical body having a ventilation hole 24 is cut diagonally, and this
Although it was fixed to the upper end of the cap, it may also have a shape that also serves as a cap, as in the previous embodiment.

Yet another embodiment is shown in FIGS. 4(a) and 4(b).

Also in this embodiment, the connection between the container 1 and the cartridge 6,
The internal structure of the cartridge is different from the first embodiment.

As shown in the figure, the container 1 has a cylindrical shape with an opening at its upper end. The cartridge 6 is provided with a cylindrical skirt 30 projecting around its body. Then, the opening periphery 8 of the container 1 is inserted into the gap 31 between the skirt 30 and the body, and by the attraction force of the magnet 28 provided in this part, the embodiment shown in FIG. Similarly, the connection is fixed and can be easily removed. In this embodiment as well, the connection and fixation of the container 1 and the cartridge 6 may be performed by screwing together. This embodiment is also similar to the previous two embodiments in that the connecting portion is provided with a seal 9 serving as a sealing means.

As shown in the diagram, the structure inside the cartridge is such that the partition wall has hole 1.
The embodiment is the same as the embodiment shown in FIG. Therefore, when using the oxygen generator of this embodiment, the same operation as in the embodiment of FIG. 3(a) may be performed. First, remove the stopper 12b that locks the operating rod 12' to prevent it from being pushed inadvertently, and push the operating rod 12' toward the inside of the container. The tip breaks through the isolation film 29 attached to one end of the cylindrical body 13. Subsequently, the film 15 pasted so as to cover the hole 14 of the cartridge 6 is pierced by the operation R12', and the inner space of the container and the first. communicates with the second space,
The oxygen generating agent 10 and the catalyst 8 are put into the water 3, a reaction is started, and oxygen is generated. The generated oxygen passes through the cartridge 6, the filter 20, and the discharge port 23, as shown by the arrow in FIG. and inhaled.

It should be noted that in this embodiment as well, the shape of the mask 22 used in the embodiment of FIG. 1(a) can be used, as in the embodiment of FIG. 3(al). Alternatively, a third partition wall may be added to the embodiment shown in FIG. 1(a).
It is also possible to use a knockout, such as the embodiment in figure (a). This also applies to other parts; for example, if a cartridge has a connection part as shown in FIG. 3(a) or FIG. 4(a), the implementation of FIG. You can also combine the internal structures of the examples and vice versa.

Up to now, the oxygen generator of the present invention has been explained based on the above three embodiments, but the structural shape of the present invention is not limited to the embodiments shown in the figures. For example, the container may have a structure in which a partition wall, an operating rod, a discharge port, a mask, etc. are provided, and the shape of the container or cartridge does not have to be cylindrical as shown in the figure. The opening means for breaking the partition wall is not limited to the operating rod, and any shape or method depending on the structure of the partition wall can be used. In these Examples, the agent that generates oxygen upon contact with water is composed of two components, the peroxy carbonate and the catalyst, but in the oxygen generator of the present invention, the agent is As long as it generates oxygen when it comes into contact with water, it may be one component or one that consists of three or more components, and the number of spaces for accommodating the drug may be the same. good. Even if the drug has two components as in the above example, one component can be wrapped in a water-soluble film and placed in the same space as the other component. , only one space is required. Further, in the above three embodiments, the cartridge was provided above the container, but the positional relationship between the container and the cartridge may be reversed, that is, the container containing water may be provided above the cartridge. . At least, if the cartridge containing the oxygen-generating agent is replaceable, other parts, such as the operating rod, mask, filter, etc., are likely to be replaced at the same time as the cartridge. may also continue to be used without being replaced.

In short, other configurations are not particularly limited as long as the cartridge containing the oxygen-generating agent is replaceable.

As described above, the oxygen generating device of the present invention is easy to operate because oxygen can be generated by simply pushing the operating rod that is the opening means for opening the partition wall.
The internal structure is also simple. Moreover, the cartridge containing the oxygen-generating agent can be easily replaced. Therefore, when the drug becomes unusable after being stored for a long time, or even after one use, it can be used again by replacing the cartridge and discarding the used solution, making it inexpensive. Moreover, it is possible to obtain an oxygen generating device with less waste (those used only once and then thrown away).

〔Effect of the invention〕

The oxygen generator of the present invention is configured as described above, and can generate oxygen simply by opening the partition wall, which simplifies the structure and operation. Since the cartridge containing the drug can be easily replaced, it can be used many times over a long period of time, resulting in an inexpensive and waste-free product.
