Description

  The present invention relates to a carbon dioxide treatment device in which carbon dioxide is brought into direct contact with the skin and mucous membrane of a living body.

Conventionally, carbon dioxide (carbon dioxide: CO ₂ ) permeates the living body's skin and mucous membranes to penetrate the living body's subcutaneous and submucosal membranes, and has the effect of improving blood circulation by expanding the blood vessels at the site of penetration. It has been known. The vasodilatory action and blood circulation promoting action exert various physiological effects such as lowering blood pressure, improving metabolism, and promoting the elimination of pain substances and waste products. It also has normalization of skin and mucous membrane, anti-inflammatory and antibacterial effects due to blood circulation promoting action. Therefore, in recent years, carbon dioxide gas has attracted widespread attention not only for medical purposes but also for health promotion and beauty promotion.

  Carbon dioxide in living tissues has a function of releasing oxygen transported by binding to hemoglobin in red blood cells. At high carbon dioxide concentrations, red blood cells release more oxygen. Thus, the supply of oxygen to cells by red blood cells is mainly controlled by carbon dioxide. In other words, without carbon dioxide, hemoglobin remains in an oxygen-bound state, and the cells cannot receive oxygen. In this way, carbon dioxide tends to appear as a waste product resulting from cell activity, but in fact it plays a very important role in the body, so it can treat injuries, gangrene, frostbite, etc. Carbon dioxide has also been used.

In the treatment of injuries, gangrene, frostbite, etc., a method of percutaneously absorbing carbon dioxide gas by covering the affected area locally is generally employed. As techniques for absorbing carbon dioxide gas in a relatively narrow part of a living body, the following have been disclosed so far.
(1) A device that mounts a hermetic simple cover locally on a human body and introduces carbon dioxide gas into the simple cover to perform a carbon dioxide bath (for example, see Patent Document 1).
(2) A device that inserts a local part of a human body into a sealable container (or attaches a sealable container to a local part of the human body) and introduces carbon dioxide into the container to perform a carbon dioxide bath (for example, Patent Documents) 2).
(3) A hermetic envelope comprising a bag, a cylindrical body, a partially opened container, etc., is attached to the local area of the human body, and an absorption auxiliary material that assists percutaneous absorption of carbon dioxide gas is sealed in the hermetic envelope. A device for sealing and performing a carbon dioxide bath by introducing carbon dioxide into the hermetic enclosure (see, for example, Patent Document 3).
(4) In order to flow a pressurized gas such as carbon dioxide from the delivery conduit to the patient interface, a diffusion member made of a porous material is provided to release the pressurized gas provided on the annular surface of the central orifice to the atmosphere. A ventilation adapter for treating respiratory pressure (see, for example, Patent Document 4).
(5) A cosmetic device that discharges carbon dioxide gas supplied from a gas storage unit in a state of being divided from a porous gas discharge unit (see, for example, Patent Document 5).

Japanese Patent Laid-Open No. 07-171189 JP 2007-252871 A Republished patent WO2004 / 002393 Special table 2018-53124 JP 2017-086213 A

  However, the conventional apparatus for a carbon dioxide gas bath described in the above-mentioned known literatures 1 to 3 uses a carbon dioxide gas cylinder or the like in order to introduce carbon dioxide from the outside into a container or bag body containing carbon dioxide. A carbon dioxide supply device must be connected, and the equipment becomes large, which hinders the free movement of the patient and makes it unusable. Moreover, in order to put the device into practical use, if the volume of the container or bag body is increased to some extent so that it can accommodate various body shapes of the user, the carbon dioxide gas There was a problem that a large amount of was consumed. In addition, in order to form a closed space for containers, bags, etc., even a small one has a large capacity and requires a large amount of carbon dioxide.

  Further, the above-mentioned known document 4 and known document 5 merely use the porous material as a flow rate / pressure adjusting member, a filter member in a gas flow path, or a gas diffusion member, and a large amount of gas is used. From the porous material as the contained gas storage body, the gas was not gradually released and utilized.

  In view of the above-described conventional problems, an object of the present invention is to provide a carbon dioxide treatment device that is not required to be connected to a carbon dioxide supply device and is downsized.

  The present invention relates to a carbon dioxide treatment device that absorbs carbon dioxide into the living body from the skin of a living body, and includes a cover having an adhesive portion that adheres to the skin, and a pad that covers the cover so as to face the skin. A carbon dioxide gas holding body that is provided on the pad and is made of a porous material containing carbon dioxide gas in the pores, and the carbon dioxide released from the carbon dioxide gas holding body is brought into contact with the skin. And

  At this time, if the porous material is, for example, a porous metal complex, it is possible to artificially design the pore structure, the specific surface area, the form, etc. in the process of producing the carbon dioxide gas holding body. The amount of gas adsorption can be improved.

  Further, when the porous metal complex is formed from a metal fiber as a raw material, in one embodiment, the porous metal complex is formed of a porous metal complex made from an iron fiber as a raw material, and the pad has a reaction aid for an oxidation reaction. Add agent. As a result, the carbon dioxide holding body has a function of warming the affected part by the heat generated by oxidation of iron in addition to the function of releasing carbon dioxide. Since the circulation of the affected area is improved by warm heat, carbon dioxide gas binds to hemoglobin in erythrocytes and effectively releases oxygen carried, thereby improving the therapeutic effect.

  As another embodiment of the carbon dioxide treatment device that also has a thermal effect in this way, a sheet-like heating element that generates heat by the oxidation action of iron powder may be provided on the pad.

  Furthermore, in another embodiment, the cover is configured to adhere to the skin with a space between the skin and the carbon dioxide holding body. By providing the space part, there is an effect of moisturizing the affected part.

According to the present invention, a carbon dioxide gas generator is not provided outside by holding the carbon dioxide gas with a large number of pores of the porous material. And since the structure which permeate | transmits a carbon dioxide gas to skin by sticking a pad, the member which forms closed spaces, such as a container and a bag body, is not required. The carbon dioxide treatment device according to the present invention has the following various effects.
(1) Since the internal pressure of the cylinder is not high and the cylinder can be made of carbon fiber reinforced plastic, etc., it is lightweight, easy to carry and safe (no risk of explosion / explosion), and can be used safely in medical institutions and homes. it can.
(2) Since the pressure of the gas or gas mist contained in the cylinder is not high, a complicated mechanism such as a pressure control mechanism (regulator or the like) is not required.
(3) The particle size of the gas or gas mist ejected from the cylinder is as it is and is nano-sized, and a mechanism for making fine particles such as gas mist is not necessary. Nano-sized gas and gas mist have extremely excellent permeability to the skin.
(4) The gas or gas mist stored at body temperature is not produced because the gas or gas mist is not rapidly compressed and stored in a cylinder at a high pressure, and the gas is not blown out into the atmosphere at once. The temperature does not drop significantly after ejection.

The perspective view of the carbon dioxide treatment device of the present invention is shown. AA sectional drawing of FIG. 1 is shown. The perspective view of a carbon dioxide gas holding body is shown. The structure of a heat generating body is shown with the side view of a partial cross section.

  FIG. 1 is a perspective view showing a configuration of a carbon dioxide treatment device 1 according to an embodiment of the present invention. FIG. 2 is a cross-sectional view of the carbon dioxide treatment device 1 taken along line AA in FIG. The carbon dioxide treatment device 1 is configured by covering a pad 2 with a cover 3 made of a breathable film member.

  The pad 2 is configured by stacking a flat carbon dioxide gas holding body 4 and a heating element 5 vertically with an adhesive layer 6 interposed therebetween. As shown in FIG. 3, the carbon dioxide holding body 4 is made of a porous material having a large number of pores, and takes in and holds carbon dioxide in the pores. As the porous material, a porous metal complex which is a structure in which a pore structure is formed by accumulation of metal complex molecules is preferable. Although porous materials such as zeolite and activated carbon can be used, it is difficult to produce these materials by precisely controlling the pore structure and specific surface area. However, if a porous metal complex is used, it is possible to artificially design the pore structure, specific surface area, morphology, etc. by accurately incorporating coordination bonds into the molecular design. Can be improved.

A porous metal complex can be obtained by applying a very high pressure to a web made of metal fibers made of a porous molded body to plastically deform the metal fibers to produce a molded body and sintering the molded body. . Examples of the material of the metal fiber that is the source of the metal complex include copper, copper alloy, titanium, titanium alloy, and the like. However, the types of materials constituting these are not particularly limited. Metal fibers having any fiber diameter can be used, but those having a large fiber diameter are difficult to be uniformly deformed, and are preferably 500 μm or less, and the optimum fiber diameter is between 10 μm and 150 μm.

  Here, as a first example of a porous metal complex having a gas adsorption action, at least one compound selected from dicarboxylic acids represented by HOOC-R-COOH, a ruthenium metal salt, and a halogen ion are used. There are known structures of dicarboxylic acid metal halide complexes that are inexpensive, have high gas adsorption capacity per volume, and have good repetitive characteristics and gas storage performance (for example, Japanese Patent Application Laid-Open No. 2000-109493). Publication).

  As a second example, the paddle wheel has a paddle wheel structure represented by [CuX] n, in which two units in which copper ions are coordinated to four carboxyl groups are vertically coordinated. Are connected by an isophthalic acid derivative to form a kagome structure composed of a six-membered ring and a three-membered ring, and a structure in which the kagome structure is laminated is known (for example, Japanese Patent No. 5646789). Publication).

  By placing such a porous metal complex in a sealed space and supplying carbon dioxide gas having a high concentration and high pressure to the sealed space, a large amount of carbon dioxide gas is contained and accumulated in the porous metal complex. .

  As shown in FIG. 4, the heating element 5 is configured by inserting a heating agent 9 containing a reaction aid containing iron powder as a main material in a flat bag 8 and sealing the peripheral side of the bag 6 8 a. It is known as a so-called disposable body warmer that utilizes an exothermic reaction by supplying oxygen (air).

  Carbon dioxide gas is gradually released from the porous metal complex containing a large amount of carbon dioxide gas by the action of body heat generated by the human body due to the heat energy generated by the heating element 5, and subcutaneously inside the body. It will be absorbed and used.

  The cover 3 has a storage portion 3a in which the pad 2 can be accommodated, and an adhesive portion 3b to be attached to the skin is provided on the peripheral portion of the storage portion 3a by applying an adhesive. The pad 2 is stored in the cover 3 with the heating element 5 bonded to the top surface of the storage portion 3a. The height to the top surface of the storage portion 3a is set to be larger than the thickness of the pad 2, and when the cover 3 is attached to the skin with the adhesive portion 3a, there is a space between the pad 2 and the skin. 7 is formed. This space 7 becomes a gap for moisturizing the skin.

  The cover 3 is sealed in the storage portion 3a with a release film 10 such as a polyethylene film that adheres to the adhesive portion 3b. Therefore, after the pad 2 is sterilized and sterilized, it is stored in the storage portion 3a and sealed with the release film 10. As shown in FIG. 1, the carbon dioxide treatment device 1 is hermetically sealed and packaged in an outer bag 11 made of a non-breathable sheet, with the cover 3 being sealed with a release film 10. The gas is stored sealed.

  When the outer bag 11 is broken and taken out when the carbon dioxide treatment tool 1 is used, the heating element 5 generates heat when oxygen in the air passes through the cover 3 and reacts with the heating agent 9. Then, the release film 10 is peeled off from the cover 3, and the carbon dioxide released from the carbon dioxide holding body 4 is percutaneously absorbed into the affected part by attaching the pad 2 to the skin with the adhesive part 3b so that the pad 2 faces the affected part. Will be. At this time, the blood vessels in the affected area are expanded by the heat generated from the heating element 5 and blood circulation is improved, so that the oxygen transported by the carbon dioxide gas released from the carbon dioxide holding body 4 being bound to the hemoglobin in the red blood cells is transferred to the affected area. Effectively released, the therapeutic effect is enhanced.

  In the above embodiment, the pad 2 is constituted by the carbon dioxide holding body 4 and the heating element 5, but the pad 2 including only the carbon dioxide holding body 4 may be used.

  Furthermore, as another embodiment, the carbon dioxide gas holding body 4 can be constituted by using a porous metal complex made of iron as a raw material and adding a reaction aid for the oxidation reaction. In the pad 2 having such a structure, the carbon dioxide holding body 4 has a thermal action by generating heat by oxidizing itself in addition to the release of the carbon dioxide. In addition, since the pores are deteriorated by oxidation at this time, the carbon dioxide gas is easily released, and the carbon dioxide gas can be effectively brought into contact with the affected part in a short time. In this embodiment, since the carbon dioxide holding body 4 also generates heat, the pad 2 may not include the heating element 5, but the thermal effect is improved by further including the heating element 5. Needless to say.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment, Based on the meaning of this invention, various deformation | transformation are possible, These are excluded from the scope of the present invention. is not.

  The present invention relates to a carbon dioxide treatment device for improving blood circulation by directly contacting carbon dioxide with the skin and mucous membrane of a living body, and has industrial applicability.
