Description

Detailed Description of the Invention (Field of Application of Industry-1-) The present invention relates to a portable urine collection bag and an ostomy bag, and more specifically, the present invention relates to a portable urine collection bag and ostomy bag. The present invention relates to a bag that can be reliably filled with water without leaking, and that can be thrown away together with the bag in a flush toilet or the like when discarded.

(Prior art) Most of the filth bags currently on the market, such as portable urine collection bags, solidify excreted water-containing filth with a superabsorbent polymer, etc., and store it in a bag made of water-impermeable material. It holds solidified filth. As for how to dispose of it, should you throw away the used waste bag along with the solidified waste as general garbage?

Or, dump the &J, which is solidified filth, into the toilet.

Garbage bags are disposed of by being disposed of as regular garbage.

In addition, regarding the male 1 me bag, the conventional ostomy
The bags are made of films such as low-density polyethylene and soft polyvinyl chloride that do not dissolve or disperse in water. And the used male) me bag is -
It is treated as garbage that is collected on a weekly basis.

For example, Japanese Patent Application Laid-Open No. 63-181758 describes a colostomy budge that can be disposed of in running water, and one layer of laminate 1 is made of hot water-soluble and durable tissue material. It is not dispersing and has a negative impact on the functioning of the toilet.

(Problems to be Solved by the Invention) The currently commercially available filth bags such as the portable urine collection hack and the male 1-me bag described above are excellent in retaining filth and leak-proofing, but are not leak-proof. Since the materials used are polymers such as polyethylene, which are insoluble in water, it is expected that if they are disposed of in a flush toilet, it will have a negative effect on the drainage system. The problem was that the process was cumbersome.

The present invention can hold waste for a relatively long time,
Another object of the present invention is to provide a portable urine collection bag and a male to me bag that can be disposed of in a flush toilet.

(Means for Solving the Problems) The inventors of the present invention have conducted extensive research to achieve the following objectives: -1.The inventors have discovered the gel formation mechanism of polyvinyl alcohol and the water repelling function of water repellent agents. By combining these, the water impermeability of one side of the film is dramatically increased, and when the film is disposed of in water, it can be dissolved or dispersed in water in a short time, making it suitable for portable urine collection bags and ostomy bags. Headline 2 found to be useful as
This has led to the present invention.

Zunawara 2 The gist of the present invention is as follows.

(1) A film J made of polyvinyl alcohol with a degree of saponification of 70 to 98% and a polyvinyl alcohol gelling promoter, and one side of which is coated with a water repellent; the surface coated with the water repellent. A portable urine collection bag that is shaped so that the inside is inside.

(2) A film made of polyvinyl alcohol with a degree of saponification of 70 to 98% and a gelling promoter of polyvinylalnyl, one side of which is coated with a water repellent; A male 1-me bag shaped so that the side faces inside.

Two aspects of the present invention will be described in detail below.

Mass, polyvinyl alcohol refers to polyvinyl alcohol or a derivative thereof. Polyvinyl alcohol is
1 by a known method such as producing polyvinyl acetate by polymerizing vinyl acetate, that is, by deaceticating it.
I am floored. In this process, the degree of hydrolysis is called the degree of saponification, and the degree of saponification is a measure of how many of the monomer units of polyvinyl alcohol have been deacetated. For example, a degree of saponification of 100% means
It means that all the acetate residues of polyvinyl acetate have been hydrolyzed to hydroxyl groups, and polyvinyl alcohol with a degree of saponification of 95% means polyvinyl acetate in which 95% of the monomer units have been substituted with hydroxyl groups. .

The polyvinyl alcohol used in the present invention is.

The degree of saponification is 70 to 98%, and the polyvinyl alcohol is not particularly limited to 6 years as long as it dissolves, swells, or disperses in water at a temperature of about 40° C. or less. Furthermore, there is no limit to the molecular weight of polyvinyl alcohol, that is, the degree of polymerization; for example, it is also possible to use a blend of polyvinyl alcohol with a low degree of polymerization and a polyvinyl alcohol with a high degree of polymerization. Furthermore, about 4
If it dissolves, swells, or disperses in water at temperatures below 0°C, it is a binary, ternary, or quaternary copolymer containing a monomer that can be copolymerized with vinyl acetate as a polyvinylalnylene monomer. It doesn't matter if there is.

Examples of monomer components that can be copolymerized include 1,000 polymers having a double bond in one molecule.

- Methylvinyleral, styrene, vinyl chloride, allyl alcohol, acrylic acid and its esters, tutaacrylic acid and its esters, acrylonitrile, vinylpyrrolidone, to name a few.

Examples include chloroprene, butadiene, isoprene, ethylene, propylene, and the like.

The polyvinyl alcohol gelation promoter used in the present invention refers to salts that have a coagulating effect on polyvinyl alcohol, substances that can form diol-type chemical bonds with polyvinyl alcohol, and the like. The salts preferably used in the present invention include:

Sulfates such as sodium sulfate, magnesium '6N acid, aluminum sulfate, ammonium sulfate, potassium sulfate, sulfuric acid nitrate, ammonium nitrate J1. Examples include nitrates such as aluminum nitrate, phosphates such as sodium phosphate, and chromates such as potassium chromate J. In addition, substances that can form the above chemical bond with polyvinyl alcohol include boric acid and borates.

Borax, copper, aluminum, titanium, zirconium.

Examples include compounds such as tin and vanadium.

The ratio of these gelling promoters to polyvinyl alcohol varies depending on the gelling ability of each gelling promoter to the monomer unit of polyvinyl alcohol.
The content is preferably 0.1 to 30 mol%, preferably 0.1 to 20 mol%. If the gelling agent concentration is lower than 0.1 mol%, the water impermeability required of the film will be poor, and if it exceeds 30 mol%, the film will not have sufficient water solubility, and the desired The desired film performance cannot be obtained.

The film containing the gelling agent and polyvinyl alcohol in the present invention can be produced by various methods. Preferably, the polyvinyl alcohol is
After dissolving, swelling or dispersing in water at an appropriate temperature by a known method, an aqueous solution or dispersion of a gelling accelerator is added, and the gelation promoter is dissolved, swollen or dispersed in water at an appropriate temperature. It can be manufactured through the steps of mixing with stirring, casting, and drying. A heat treatment step may be added to increase the film strength.

The film used in the present invention is obtained by applying a water repellent to one side of a polyvinyl alcohol film containing a gelling promoter obtained under the following conditions using a known method such as coating or spraying. Te: Obtained by 1-ting.

In general, water repellent agents are called water repellent finishing, which means adding properties to the film surface to resist wetting (wetting) by water.
Refers to the drug used for this purpose.

Water repellents are commonly used for surface treatment of textile products, especially textiles. To make the surface water repellent.
