BEST MODE FOR CARRYING OUT THE INVENTION The present invention is directed to a portable sterilization bag which is excellent in ease of handling and which is lightweight and can be subjected to a sterilization treatment which can be moved. When we adopted bags, we found that we could solve these problems at once. That is, the portable sterilization bag of the present invention can further impart functions such as water repellency, bacteriostatic properties, deodorant properties, and antifouling properties. Home treatment
It is excellent for easy use in medical treatment. The portable sterilization bag of the present invention does not require a special space unlike conventional installation-type equipment and can be manufactured at low cost, so that it has excellent versatility.

The planar heating element of the present invention is planar and
There is no particular limitation as long as it can generate an exothermic temperature in the range of 70 to 200 ° C. Known planar heating elements having such a function include, for example, electric carpets, floor heating,
A heating element widely used for a snow melting apparatus, a ceramic fan heater, a heating heater for a pipe or a tank, or the like can be used.

[0008] A heating element (heater) of the sheet heating element.
The structure of the part is composed of a heating part, a temperature control part and a safety device part.

As the heater portion of the sheet heating element, the following eight types can be roughly classified.

1) A sheet or wire formed by uniformly dispersing conductive particles such as carbon black in a thermoplastic resin such as polyester, polyethylene, or polyolefin. Since the carbon particles are in physical contact with each other, the resistance value is small and conduction is obtained. The body thermal expansion coefficient of carbon and thermoplastic resin, which are conductive particles, is extremely large for the resin, and the resin exhibits a larger thermal expansion coefficient at or above the glass transition point.
The interval between the dispersed carbon particles expands with an increase in temperature, and the expansion is accelerated above the glass transition point, so that the resistance value increases and a remarkable PTC (positive resistance-temperature characteristic) characteristic is exhibited. No current flows through the heating element before and after, and it has a self-temperature control characteristic (positive characteristic thermistor). Products that make use of this include electric blankets and hot carpets.

2) By adding the special semiconductor fine particles and the carbon particles to the thermoplastic resin described in the above item 1, a heating element having a higher temperature characteristic (PTC) than the above-described carbon particles alone can be obtained, Can have a self-temperature control characteristic. Utilizing this, it is used for floor heating, road snow melting heaters, and anti-freezing heaters for tanks and piping.

3) A mixture of conductive particles mixed with a silicone resin or frit glass, mixed with an organic vehicle, applied on a heat-resistant insulating substrate, and baked. For example, Japanese Patent Publication No. 58-159
No. 13 discloses the contents of the publication,
Graphite powder, organic solvent, silicone resin varnish
A method is described in which a fluidity modifier is mixed, coated on a heat-resistant insulating substrate, and baked at 250 to 450 ° C. for 3 hours to produce a sheet-like heating element having a surface temperature of 200 to 360 ° C. It is shown that it can be made, and it is specified that the stability of the resistance value is good.

4) The fired body itself is a heating element, and P
Barium titanate-based devices having TC temperature characteristics (positive resistance-temperature characteristics) have a unique temperature resistance characteristic in which the resistance value rises extremely at temperatures above the Curie point of the device (rapid temperature change). And its Curie point can be controlled from room temperature to about 300 ° C. by partially replacing barium in barium titanate with strontium, calcium or lead. For this reason, it is widely used for various heat sources such as a washing dryer, a futon dryer, and a hot air heater.

5) A thin stainless steel sheet or aluminum thin film formed on an aluminum plate or an enameled substrate subjected to insulation treatment by etching or mechanical pressing to form a thin line-width pattern, and then formed into a silicone resin or inorganic adhesive. The one that was attached with is used as an auxiliary heater for digging kotatsu.

6) A sheet heater having no PTC characteristics obtained by coating a resin such as polyurethane with conductive carbon particles added onto a polyester film or the like in a sheet form and drying the sheet is used for electric blankets and the like. ing.

[0016] 7) There is a heater in which a conventionally used nichrome wire is sewn to a fabric.

8) A PT wherein the core yarn is made of a spun yarn of polyester and the circumferential portion (sheath) is made of a resin containing conductive carbon particles.
There is a planar heating element made by weaving a thread-like heating element having no C characteristics into a weft yarn during weaving, and is used for an electric blanket, a health insulation mat, a car seat insulation mat, and the like.

When the substrate is used in such a planar heating element, it is made of a flexible woven or knitted fabric, a non-woven fabric, or a fiber cloth or an insulating film and a fiber cloth for use in a bag state. Is preferably used.

It can be used everywhere, especially for portable use.
Those having a range of １０００1000 g / m ² are preferred. The shape may be any shape as long as it is a bag-like shape, but is more preferably a circular cylindrical bag-like shape, and is preferably a size that is portable. In addition, it is more preferable that a string, a handle, or the like is provided so that it can be hooked somewhere.
FIG. 1 is a schematic diagram of the shape.

The fibrous structure of the present invention is not particularly limited, and the fineness of a single fiber is 0.1 to 11
Fibers in the range of dTex and made of a woven or knitted fabric or a nonwoven fabric are preferably used. Among them, those composed of at least one selected from polyester fibers and polyamide fibers are more preferably used. Further, fluorinated fibers, aramid fibers, and glass fibers, which are flame-retardant fibers, can also be preferably used.

As such polyester fibers, polyethylene terephthalate, polypropylene terephthalate, polybutylene terephthalate, polyhexamethylene terephthalate and the like are preferably used, but those obtained by copolymerizing the third component can also be used. Further, nylon 66, nylon 610, nylon 12, and the like are preferably used as the polyamide fibers. Also, aramid fibers can be used, and in that case, either para-based or meta-based fibers may be used. When such a fiber structure is used, a material obtained by impregnating a fiber cloth with a substance to be a heating element or coating one or both surfaces thereof can be used. FIG. 2 shows, by way of example, a schematic cross-sectional view of a woven fabric impregnated with a heating element.

When a film is used as the base of the heating element, a synthetic film is used as the base. Such a film may be broken if the thickness is too small, and the texture may be hard if the thickness is too large.
Those having a thickness in the range of 100 μm are preferred. When such a film is used, it can be obtained by coating a material to be a heating element on one side of the film. FIG. 3 as an example
FIG.

Among such planar heating elements, a planar one obtained by impregnation or coating generates less eddy current than a linear heating element by alternating current, so that almost no electromagnetic waves are generated. It can be said that it is a heating element that is convenient especially for people with weak body.

The covering fiber cloth used in the present invention may be any of ordinary natural fibers, semi-synthetic fibers and synthetic fibers, or may be a mixture of natural fibers and synthetic fibers. Among them, a woven or knitted fabric or a nonwoven fabric mainly composed of synthetic fibers having a single fiber fineness in the range of 0.1 to 11 dTex is preferably used. Among them, those composed of at least one selected from polyester fibers and polyamide fibers are more preferably used. Further, it is preferable to use flame-retardant fibers such as fluorinated fibers, aramid fibers, and glass fibers.

As the polyester fiber, polyethylene terephthalate, polypropylene terephthalate, polybutylene terephthalate, polyhexamethylene terephthalate and the like are preferably used. As the third component, isophthalic acid, 5-sulfoisophthalic acid, methoxypolyoxy Those obtained by copolymerizing ethylene glycol or the like can also be used. Further, nylon 66, nylon 610, nylon 12, and the like are preferably used as the polyamide fibers. Also, as the aramid fiber, either a para-based or a meta-based fiber may be used.

In general, water is easily permeated into a fiber cloth, and therefore, water repellency is preferable also from the viewpoint of preventing permeation of water-based dirt and preventing electric leakage. JIS states that fiber fabrics have water repellency
Water repellency measured based on L-1092 refers to a material having a performance of 70 points or more. A known process may be used as the water repellent process for imparting such water repellency.
In order to provide durable water repellency, processing using a fluorine-based water repellent in combination with a melamine compound, an isocyanate compound or the like is preferably employed.

As the fiber fabric of the present invention, a fabric having antibacterial properties is preferably used. Here, that the fiber cloth has antibacterial properties means one having a certain level or more of antibacterial properties in the antibacterial evaluation method described later. As such antibacterial processing, ordinary antibacterial processing may be used. As an example, a method in which an inorganic antibacterial agent such as silver, copper or zinc is kneaded in the spinning step of synthetic fibers, and a method in which an organic antibacterial agent represented by a quaternary ammonium salt is applied by spraying or padding. There is a processing method. On the other hand, there is a method in which a pyridine-based antibacterial agent having a specific molecular weight is exhausted into fibers by dry heat treatment or wet heat treatment. The unified test method was adopted for the evaluation method of antibacterial properties, and MRSA clinical isolates were used as test cells.

As the fiber cloth of the present invention, a cloth having a deodorizing property is preferably used. The fact that the fiber cloth has a deodorizing property refers to a processed cloth having a deodorizing effect on an undeodorized unprocessed product, and the deodorizing is a state in which an odor is hardly attached to the cloth itself (an odor preventing effect), Or the smell of the atmosphere is reduced.

As the deodorizing process, specifically, for example, a deodorant is kneaded into a yarn, applied in a spinning process, and applied at the time of dyeing and after dyeing. As a deodorant, an inorganic deodorant such as activated carbon, silica, zeolite, and calcium phosphate. Examples include an amine compound, an organic deodorant having a carboxylic acid group or a sulfonic acid group, and an anatase type titanium oxide having a photocatalytic function.

As the fiber cloth of the present invention, a cloth having antifouling properties is preferably used. Here, the term “fiber cloth having antifouling properties” refers to a processed cloth in which dirt hardly adheres to an antifouling unprocessed product and dirt is easily removed during washing. As a specific antifouling method, for example, there is a method of treating a fiber cloth with a water and oil repellent comprising a fluorine compound or a silicone compound, or a method of treating the fiber cloth with a hydrophilic resin such as polyethylene glycol. There is a method of treating dark stains in the atmosphere with a highly inorganic processing agent such as a modified organosilicate. The optimum processing agent and processing method can be selected and used depending on the type of dirt.

It is preferable that the fiber fabric of the present invention is removably attached. Here, that the fiber cloth is detachably attached means that it can be easily separated from the heating element. Specifically, the release portion is provided so as to be closed with a fastener, a hook-and-loop fastener, a button, a hook, a string, and the like, whereby the fiber cloth (cover) can be easily removed by hand,
It is intended to make washing easy.

Since the present invention is intended for sterilization,
It is essential to use a heating element that produces an exothermic temperature in the range of 70-200 ° C. Also, since the heat generation temperature is high,
The fiber fabric to be coated preferably has a heat-resistant filling. The batting may be anything as long as it has heat resistance, but one composed of at least one selected from fluorine fiber, aramid fiber and glass fiber is more preferably used. Such batting plays an insulating role, which is convenient for safety.
