DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention effectively prevents and relieves pressure ulcers (so-called bedsores) which tend to occur in patients such as the elderly who are unable to act on their own and who are unable to act on their own (hereinafter referred to simply as patients). For sanitary materials that can be.

[0002]

2. Description of the Related Art A pressure ulcer is a risk factor for the onset of perception and cognitive ability of a patient, the degree of skin moistness, activity, mobility, nutritional status, as well as friction and slippage between the skin and objects in contact with the skin. The evaluation method of the factors is the Braden scale (Bra
den scale).

[0003] A method for preventing pressure ulcers is to change the body position at regular intervals by a caregiver to remove pressure on a fixed portion over a long period of time, to clean the skin with hot water or massage, etc.
It is said to promote drying and blood circulation, reduce friction with the skin using hygroscopic bedding, do not cause trauma, and improve the nutrition of the whole body. In addition, the treatment method is effective in the initial stage, disinfection, the application of a hydrocolloid dressing material after wiping is effective, after the middle stage, in addition to removal of necrotic tissue by surgical debridement, silver sulfadiazine preparation, purified sucrose, An external preparation such as an ointment containing povidone-iodine is effective, and when there is a large amount of exudate, a cadoxomer iodine preparation, a dextran polymer preparation, or the like can be used. In the final stage, besides tretinointocopheryl ointment, lysozyme chloride ointment, etc., sodium bucladesin ointment, hydrocolloid dressing and the like are used.

[0004] It should be noted that pressure ulcers are injuries that are extremely difficult to treat because there are no drugs that can be used in common at each stage.
It is a well-known place.

[0005]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to prevent pressure ulcers by using a carbonaceous material having a broad antibacterial spectrum against various bacteria of pressure ulcers in view of the state of the prior art. An object of the present invention is to provide a sanitary material that can be used effectively for treatment.

[0006]

The gist of the present invention to achieve the above object is to form a sheet and have a carbon-based material.

[0007] The carbon-based material may be activated carbon.

[0008] Further, the carbon-based material may be any of powdery, granular, and fibrous.

The carbon-based material can be provided with an inner surface material and an outer surface material.

[0010]

According to the constitution of the present invention, the carbonaceous substances include standard strains of Staphylococcus aureus Smith strain, S. pyogenes Streptococcus cook strain, Escherichia coli, Pseudomonas aeruginosa and Candida, as well as methicillin-sensitive Staphylococcus aureus and methicillin resistant. Staphylococcus aureus, Streptococcus pyogenes, group B hemolytic streptococci, enterococci, Escherichia coli, deformed bacteria, bacterium-like bacteria, multidrug-resistant strains of Pseudomonas aeruginosa, Altophilia, microaerobic streptococci, anaerobic gram Positive cocci, C. perfringens, anaerobic gram-positive bacilli,
Shows broad antibacterial properties against pressure ulcer-derived bacteria such as anaerobic gram-negative bacilli and yeast-like fungi. That is, it was newly found that the carbonaceous material has a broad antibacterial spectrum against many of the pressure ulcer-derived bacteria. In addition, the antibacterial activity test of carbon-based

Method) and the viable cell count over time by the shake flask method.

[0011] The carbon-based substance referred to here is charcoal,
Bamboo charcoal, coconut shell charcoal, bone charcoal, and other white coal, black charcoal, dry carbonized coal, and other natural fibers such as cotton, raw silk, and hemp, phenolic, rayon, acrylic, and pitch-based carbon fibers. That is, the carbon-based material may be powdery, granular, or fibrous, and in the former case, it may be stored in a thin bag to form a planar structure, and in the latter case, May itself be formed into a planar structure such as a woven fabric, a knitted fabric, or a nonwoven fabric, or may be formed into a planar structure by randomly filling thin bags. However, it is preferable that the bag at this time does not leak the carbon-based material and has excellent air permeability and water permeability.

[0012] The carbon-based material is formed into a planar structure and applied to a site where a pressure ulcer is likely to occur, thereby keeping the patient's skin clean and dry and reducing friction between the bedding and the skin. The occurrence of pressure sores can be prevented. Also,
By placing the pressure ulcer on a site where a pressure ulcer is actually generated, bacteria from the pressure ulcer can be adsorbed to eliminate the bacteria, prevent proliferation, and improve the therapeutic effect.

Activated carbon uses a reactive gas such as steam,
It can be produced by activating and firing a carbon-based material in an inert atmosphere such as nitrogen. Activated carbon is porous, so it has excellent adsorptivity and can achieve better antibacterial properties. The fibrous carbon-based material may be formed into a planar structure such as a woven fabric, a knitted fabric, or a non-woven fabric before the active carbonization, and may be entirely activated carbonized. It may be formed.

[0014] If the inner material is attached to the carbon-based material, the carbon-based material can contact the skin via the inner material and soften the hit. In addition, as the inner surface material, in addition to a thin cloth material such as cotton and silk, a nonwoven fabric made of a chemical fiber such as polypropylene or polyethylene that does not give a feeling of shrinkage, a porous film of polyethylene, or the like is preferable. In addition, the inner surface material is formed of a nonwoven fabric made of alginic acid or a water-retentive gel having a suitable moisture retention and air permeability in order to keep the site where the pressure sore is actually in a moderately moist state. You may.

[0015] If the carbon material is provided with an external material, the external material effectively prevents the exudate, pus, etc. from the pressure sore from leaking to the outside. The outer surface material is preferably a thin cloth material such as cotton or silk, or a thin and impermeable water-impervious material. For example, a material obtained by laminating a polyethylene film on a non-woven fabric of polyethylene is preferable.

However, when the carbon-based material is powdery, granular or fibrous and is stored in a thin bag, the bag itself may be used as an inner surface material or an outer surface material.

[0017]

BEST MODE FOR CARRYING OUT THE INVENTION A sanitary material has a carbon-based material 1, an inner surface material 2 and an outer surface material 3 attached thereto, and is formed in a planar shape (FIG. 1).

The carbon-based material 1 is, for example, carbon fiber, and is formed in a planar structure such as a woven fabric or a nonwoven fabric.
The inner surface material 2 and the outer surface material 3 are integrally provided on the lower surface and the upper surface of the carbon-based material 1.

The sanitary material is cut into an arbitrary shape and size, and the inner surface material 2 is brought into contact with the skin as a patch, a bandage, a pad or the like equivalent to a gauze.
Can be used for prevention and treatment of pressure ulcers. In addition, the hygiene material may be used as a whole or a part of a patient's bedding, bed sheets, or the like. However, for the sanitary material, one or both of the inner surface material 2 and the outer surface material 3 may be deleted depending on the application.

When the hygiene material is used as the bed sheet S of the patient M (FIG. 2), the drying air may be blown upward from below the bed B (directions of arrows A, A... In the figure). The dry air dries the area where the pressure ulcer easily occurs or the pressure ulcer itself, and can further improve its preventive effect and therapeutic effect. The sanitary materials at this time are:
At least the outer surface material 3 is removed to have sufficient air permeability. In addition, instead of using the sanitary material for the entire bed sheet S, it is used only locally at a predetermined position,
Dry air may also be jetted locally only to that position. However, the hygiene material may be used as a bed sheet for the patient M instead of the bed sheet S.

[0021]

[Other Embodiments] The carbon-based material 1 may be any of granular, powdery and fibrous (FIG. 3). Note that the carbon-based material 1 at this time is filled in a thin bag A formed from the inner surface material 2 and the outer surface material 3, and the bag A is bonded or heat-bonded to the outer peripheral portion and the intermediate portion at an appropriate pitch. By fusion, they are divided into small-volume unit bags Aa, Aa.

In the above description, the carbon-based material 1 may be activated carbon. Further, the bag A may be formed of a general cloth material having excellent air permeability and water permeability. Note that one or both of the inner surface material 2 and the outer surface material 3 may be deleted.

[0023]

As described above, according to the present invention, by forming a sheet and having a carbon-based material,
Carbon-based substances adsorb and remove bacteria from pressure ulcers and have a wide antibacterial property against many of them. Therefore, they are effective for the prevention and treatment of pressure ulcers as patches, bandages, pads, sleepwear, bed sheets, etc. It has an excellent effect that it can be used.
