JP3004351B2 - Portable urine collection bag and ostomy bag - Google Patents

Description

Description: TECHNICAL FIELD The present invention relates to a portable urine collection bag and an ostomy bag, and more particularly, to a portable urine collection bag and an ostomy bag without leakage of urine and filth discharged from a stoma during use. The present invention relates to a bag that can be stored in a bag and can be discarded together with the bag in a flush toilet at the time of disposal.

(Prior art) At present, many of the filth bags, such as portable urine bag, which are commercially available, solidify excreted water-containing filth with a high-absorbency polymer or the like, and solidify in a bag made of a water-impermeable material. It retains the converted waste. The disposal method is to dispose of used waste bags as general garbage together with solidified waste, or to dump only solidified waste into toilets and dispose of the waste bags as ordinary garbage. .

As for the ostomy bag, a film that does not dissolve or disperse in water, such as low-density polyethylene and soft polyvinyl chloride, is used for the conventional ostomy bag. The used ostomy bags are disposed of as garbage collected on a daily or weekly basis.
For example, Japanese Patent Application Laid-Open No. 63-181758 describes a colostomy pouch that can be dumped in running water in which one layer of laminate is made of hot water soluble and durable tissue paper, but is not dispersed in toilet water. ， Is affecting the function of the toilet.

(Problems to be Solved by the Invention) Currently available portable urine collection bags as described above,
Although filth bags such as ostomy bags are excellent in retaining and leak-proofing filth, they are discarded in flush toilets because water-insoluble materials such as polyethylene are used as leak-proof materials. If this occurs, it is expected that the drainage equipment will be adversely affected, and the bag cannot be discarded in the flush toilet, and there is a problem that the treatment is troublesome.

An object of the present invention is to provide a portable urine collection bag and an ostomy bag that can retain waste for a relatively long time and can be disposed of in a flush toilet.

(Means for Solving the Problems) The inventors of the present invention have conducted intensive studies to achieve the above objects, and found that the combination of a polyvinyl alcohol gel formation mechanism and a water repellent function of a water repellent is combined. As a result, the water impermeability of one side of the film is dramatically improved, and when the film is dumped in water, it can be dissolved or dispersed in water in a short time, which is useful as a portable urine bag and ostomy bag. This has led to the present invention.

 That is, the present invention has the following points.

(1) A film comprising a polyvinyl alcohol having a degree of saponification of 70 to 98% and a gelling agent of polyvinyl alcohol, wherein the film is coated on one side with a water repellent, and the surface coated with the water repellent is on the inside. A portable urine bag that is shaped to be.

(2) A film comprising a polyvinyl alcohol having a degree of saponification of 70 to 98% and a gelling agent of polyvinyl alcohol having a water-repellent agent coated on one side of the film, with the water-repellent agent coated on the inner side An ostomy bag shaped to be.

 Hereinafter, the present invention will be described in detail.

First, polyvinyl alcohol refers to polyvinyl alcohol or a derivative thereof. Polyvinyl alcohol can be obtained by a known method such as hydrolysis of polyvinyl acetate obtained by polymerizing vinyl acetate, that is, production by deacetic acid. In this process, the degree of hydrolysis is called a degree of saponification, and the degree of saponification is an amount indicating the amount of deacetic acid in the polyvinyl alcohol monomer unit. For example, a saponification degree of 100% means that all the acetate residues of polyvinyl acetate have been hydrolyzed to hydroxyl groups, and a polyvinyl alcohol having a saponification degree of 95% means that the polyvinyl acetate monomer unit is 95%. % Substituted with a hydroxyl group.

The polyvinyl alcohol used in the present invention has a saponification degree of 70 to 98%, and the polyvinyl alcohol has a saponification degree of about 40%.
There is no particular limitation as long as it can be dissolved, swelled or dispersed in water at a temperature of not more than ° C. The molecular weight of polyvinyl alcohol, that is, the degree of polymerization is not limited. For example, polyvinyl alcohol having a low degree of polymerization and a high degree of polymerization may be blended and used. Furthermore, if it is soluble, swells or disperses in water at about 40 ° C or lower, it is a binary, ternary or quaternary copolymer containing a monomer capable of copolymerizing with vinyl acetate as a monomer of polyvinyl alcohol. It does not matter. Examples of the copolymerizable monomer component include a monomer having a double bond in the molecule. For example, methyl vinyl ether, styrene, vinyl chloride, allyl alcohol, acrylic acid and its ester, methacrylic acid and its ester,
Acrylonitrile, vinylpyrrolidone, chloroprene,
Butadiene, isoprene, ethylene, propylene and the like.

The gelation accelerator for polyvinyl alcohol used in the present invention refers to salts having a coagulation effect on polyvinyl alcohol, substances capable of forming a diol-type chemical bond with polyvinyl alcohol, and the like. Salts preferably used in the present invention include sulfates such as sodium sulfate, magnesium sulfate, aluminum sulfate, ammonium sulfate and potassium sulfate, nitrates such as sodium nitrate, ammonium nitrate and aluminum nitrate, phosphates such as sodium phosphate, and chromic acid. Chromates such as potassium are exemplified. Examples of the substance capable of chemically bonding with polyvinyl alcohol include boric acid, borate, borax, and compounds such as copper, aluminum, titanium, zirconium, tin, and vanadium.

The ratio of these gelling accelerators to polyvinyl alcohol varies depending on the gelling ability of each gelling accelerator with respect to the monomer unit of polyvinyl alcohol, but may be 0.1 to 30 mol%, preferably 0.1 to 20 mol%. Is better. If the gelling agent concentration is lower than 0.1 mol%,
The water impermeability required for the film deteriorates.
On the other hand, when the content exceeds 0 mol%, the film is not sufficiently water-soluble, and the desired film performance cannot be obtained.

The film comprising the gelling agent and polyvinyl alcohol in the present invention can be produced by various methods. Preferably, polyvinyl alcohol is dissolved, swelled, or dispersed in water at an appropriate temperature by a known method, and then an aqueous solution or dispersion of a gelling agent is added, mixed with stirring, cast, and dried. It can be manufactured through a process. A heat treatment step may be added to increase the film strength.

The film used in the present invention is obtained by coating a water repellent on one surface of a polyvinyl alcohol film containing a gelling agent obtained under the above conditions by a known method such as a coating method or a spray method. Is obtained by

In general, a water repellent is a treatment that gives the film surface the performance of resisting the wetting (wetting) of the film with water.
Refers to the drug used for this. Water repellents are generally used for surface treatment of textiles, especially textiles. In order to impart water repellency to the surface, a substance that repels water is required, and compounds having a lower surface energy tend to repel water. If Shimese in chemical structure, -CF _3> -CF _2> -CH

It is generally known as a part that imparts water repellency. Further, a fluorine compound having a perfluoroalkyl group has both water repellency and oil repellency repelling an oily substance.

Typical examples of the water repellent used in the present invention include reactive silicone compounds and pyridinium which are mainly composed of paraffin, aluminum stearate, zirconium stearate, silicone resin or methylhydropolysiloxane, and which are reticulated by a catalyst. Reactive long-chain saturated hydrocarbon compounds such as salt-type cationic surfactants, methylol stearamide, octadecylethylene urea, and polyfluoroalkyl acrylates having perfluoroalkyl groups on the side chains And compounds containing fluorine in the main chain. A water repellent containing a compound having a perfluoroalkyl group having a property of repelling water and oil is preferably used, but other water repellents may be selected according to the application. Further, there is no limitation on the amount of coating and the heat treatment method after coating.

Water repellents such as those described above are prepared by emulsifying a water-repellent compound in water using a small amount of a surfactant or dispersing and dissolving in a solvent on a film surface by a known method such as a coating method. Can be coated with
Drying and heat treatment may be performed according to the application.

The thickness of the film of the present invention is not particularly limited.
A thickness of 250250 μm is preferably used.

In order to improve the flexibility of the film, a plasticizer may be added to such an extent that the performance of the film is not impaired. As the plasticizer, glycols are generally used. For example, ethylene glycol, trimethylene glycol, tetramethylene glycol, pentamethylene glycol,
Hexamethylene glycol, propylene glycol, glycerin, 2,3-butanediol, 1,3-butanediol,
Examples thereof include diethylene glycol and triethylene glycol.

Further, in order to color the film layer mainly composed of polyvinyl alcohol, a coloring agent or a dye may be added to such an extent that the performance and strength of the film are not impaired. For example, Benzopurpurine4B
