Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a medical sheet that exhibits a function of suppressing or killing bacterial growth.
[0002]
[Prior art]
It is well known that a photocatalytic semiconductor such as titanium oxide is excited by ultraviolet rays having a relatively long wavelength and exhibits a bactericidal function by its oxidation and reduction action, and is used in the medical field. For example, Japanese Patent Laid-Open No. 3-94762 proposes a method of sending a photocatalytic semiconductor to an affected part of a living body and irradiating it with ultraviolet light to excite it. Methods for reducing the infectious value have been proposed.
[0003]
However, we can find examples where the disinfection function of photocatalytic semiconductors is used to protect cuts, burns, artifacts, affected areas after surgery, or affected skin areas (hereinafter collectively referred to as traumatic affected areas) from suppuration. Absent. In order to sterilize and protect the affected area, a disinfectant is exclusively used. However, depending on the condition of the affected area, there are cases where the medicinal effect is too strong or cannot be used due to the relationship with a drug to be used later.
[0004]
Further, in order to keep the medical device after sterilization clean, it is necessary to store it in a clean room or box which is a sterilization space, or put it under irradiation of a sterilization lamp. However, it is cumbersome to put things that will be used immediately into the clean room, and even if it is a short distance in the same hospital, it cannot be placed under the sterilization lamp during transportation.
[0005]
[Problems to be solved by the invention]
The present invention relates to a material for sterilizing human skin and mucous membranes and preventing suppuration. For example, it is an object of the present invention to provide a means capable of easily performing emergency suppuration treatment for traumatic lesions and preventing contamination of clean medical devices by bacteria. To do.
[0006]
[Means for Solving the Problems]
The sheet material is loaded with a photocatalytic semiconductor to form a covering portion for the traumatic lesion.
The sheet material must be harmless even when it first comes into contact with the human body, be flexible, and be transparent to ultraviolet rays. Natural fibers such as cotton, hemp, wool, polyolefin, acetate, polyester, Mainly woven fabric, non-woven fabric, or knitted fabric made of synthetic fibers such as nylon and acrylic. Besides this, paper and synthetic leather can also be used. In any case, a texture that is soft and gentle to the affected area is preferable.
[0007]
Photocatalytic semiconductors include TiO2, ZnO, SrTiO3, CdS, CdO, CaP, InP, In2O3, CaAs, BaTiO3, K2NbO3, Fe2O3, Ta2O5, WO3, SaO2, Bi2O3, NiO, Cu2O, Si. , MoS2, MoS3, InPb, RuO2, and CeO2.
[0008]
Of these, TiO2 (titanium oxide) is commercially available, is harmless to the human body, is inexpensive, and is easy to use. "ST-01" (trade name: Ishihara Sangyo Co., Ltd.) is provided as a powder, and "TO sol" (trade name: Tanaka Transcription Co., Ltd.) and "STS-01" (trade name: Ishihara Sangyo Co., Ltd.) are provided in sol form. Has been. The particle size of TiO2 constituting the powder or sol is 7 to 20 nm and very fine.
[0009]
Various means such as spraying, coating, dipping, and sputtering can be employed for fixing (fixing) the photocatalytic semiconductor to the sheet material, and the method is selected according to the type of the sheet material. In the case of TiO2, the fixing temperature is 50 ° C. to 500 ° C. and is relatively wide. There is also a method of applying a paste-like material kneaded into a viscous material to one side of the sheet.
[0010]
The sterilization patch sheet formed in this way sterilizes bacteria adhering to the surface by oxidizing and reducing action by exciting the photocatalytic semiconductor carried by receiving ultraviolet rays of indoor fluorescent lamps or ultraviolet rays of sunlight. The sterilization patch sheet can be various in size from a wide and long one to a small one of about 1 cm ² , and the shape is also free. For example, those having a width of 30 cm and a length of 50 cm are used for wrapping a surgical instrument after sterilization and storing it for a short time, or for carrying a short distance. In this case, the internal space wrapped in the sterilization patch sheet is kept clean by the sterilization action of the sheet.
[0011]
A relatively small sterilized patch sheet is used by directly covering the wound site. In order to maintain the applied state, a bandage is wound from the upper side of the sterilization patch sheet, fastened with a band, or medical adhesive tape is used.
[0012]
Although this sheet alone does not have the ability to heal wounds, it can be used in the early stages of scratching to prevent the photocatalytic semiconductor excited by ultraviolet rays from invading bacteria from the outside, or to the wound surface. Effective in killing bacteria that have adhered. Highly effective when used outdoors with strong UV rays.
[0013]
In addition to the photocatalytic semiconductor, an ultraviolet emitter may be supported on a sheet material as a covering portion.
There are two types of ultraviolet emitters: spontaneous and phosphorescent. The spontaneous ultraviolet emitter (spontaneous luminescent ceramic) is a substance that emits light by consuming internal energy and uses the radiation decay of radium and promethium. The emission spectrum has an ultraviolet region. At present, crushed fine particles obtained by re-pulverizing a hardened rock powder containing such components are used. The particle size is 20-50 μm.
[0014]
A phosphorescent ultraviolet radiator (phosphorescent luminescent ceramic) is a substance that takes in and stores external energy and emits light while releasing the energy, and also has an ultraviolet region in the emission spectrum. Commercially available products include “Luminoba” (trade name: Nemoto Special Chemical) and “Kiplus” (trade name: Next Eye Co., Ltd.). These are mainly composed of strontium aluminate (SrAl2 O2) containing components such as high purity alumina, strontium carbonate, europium and dysprosium. Among these commercially available products, there is a product whose luminous performance is greatly deteriorated due to moisture absorption, so that it is used by being encapsulated in microcapsules of glass or synthetic resin. Ceramic type “Kiplus” has relatively strong characteristics against moisture.
[0015]
In order to support the ultraviolet emitter on the sheet material, the same means as the photocatalytic semiconductor can be used. The amount carried is, for example, about 100 mg / cm ² . In the case where synthetic resin fibers that are easily decomposed into ultraviolet rays are used as the material of the sheet, it is preferable to previously form a block layer such as silicon on the surface of the material of the sheet. In addition, in the case of a sheet material made of another synthetic resin, except for a material that is sensitive to ultraviolet rays, such as a vinyl chloride resin, an ultraviolet radiator may be mixed in the material. In the case of using a vinyl chloride resin, it is possible to weaken the material itself from being decomposed by ultraviolet rays by mixing the ultraviolet absorbing material together.
[0016]
In addition to the photocatalytic semiconductor, the sterilized patch sheet in which an ultraviolet emitter is carried on the sheet material as the coating part self-supplies the ultraviolet light necessary for excitation of the photocatalytic semiconductor inside the coating part, so that the nighttime and bandages are wound thickly. When there is no UV supply from the outside or when it is difficult, the sterilizing function can be exhibited and maintained.
[0017]
When stored for 4 to 30 minutes under a sufficiently strong external ultraviolet ray, the phosphorescent ultraviolet radiator saturates the absorption of external energy for light emission, and continues to emit light for about 1000 minutes even after the external energy is cut off. Supply ultraviolet light to the photocatalytic semiconductor. For example, the wavelength peak of absorbed ultraviolet light is 360 nm, and the wavelength peak of emitted ultraviolet light is 440 to 530 nm.
[0018]
In addition, the photocatalyst semiconductor can change the wavelength (absorption band) of ultraviolet rays necessary for exhibiting the photocatalytic function by adjusting the composition by adding an inorganic pigment or a metal or adjusting the heat treatment in the manufacturing process. . For example, when a small amount of CrO3 is added to TiO2, the absorption band moves to the long wavelength side. This makes it possible to match the photocatalytic semiconductor with these ultraviolet emitters by matching the absorption wavelength of the photocatalytic semiconductor with the emission spectrum characteristics of the phosphorescent ultraviolet emitter or the spontaneous ultraviolet emitter.
[0019]
As described above, the pasteurized patch sheet is basically provided with a photocatalytic function, and preferably has an ultraviolet radiation function. However, each sheet material is provided with a separate sheet material and used as a covering portion. May be used in combination (overlapping). With this configuration, the sheet material having the ultraviolet radiation function can be used only when necessary, or the photocatalytic function sheet material can be used by replacing the sheet material having the ultraviolet radiation function. .
[0020]
With respect to the covering portion in which the ultraviolet radiation body is supported on the sheet material, an ultraviolet reflecting layer may be provided on the opposite side of the covering portion to the surface of the human body.
The ultraviolet reflection layer is mainly formed of a metal foil such as aluminum or a film on which a metal is deposited, but may be formed by directly depositing a metal on one surface of the sheet material. In the case of a metal foil or a film, it can be used as needed for a sheet material having other functions, or can be used after being exchanged. In either case, it is prohibited to make the reflecting surface hard, and in the case of metal foil, the thickness is 7 to 12 μm.
With this configuration, the ultraviolet rays that are radiated to the outside from the covering portion can be reflected and used effectively, and the sterilization performance can be enhanced.
[0021]
A cover sheet may be integrally attached to the covering portion. The cover sheet is formed of a strong film such as polyethylene, a woven fabric, a non-woven fabric, or the like, and a covering portion is provided on the inner surface thereof. As described above, the covering portion is obtained by supporting a photocatalytic semiconductor and an ultraviolet emitter on a sheet material. The size and shape of the cover sheet differ depending on the purpose of use of the cover part and the affected part, and the cover sheet is sized so that the ends of the cover sheet can be tied together so that the object can be maintained after wrapping the target object in the cover part. Something is possible, from the size that can rotate the torso to the size that can rotate the little finger. In other words, in order to maintain the covering portion made only of the sheet material in a wrapped state or a state where the covering portion is applied to the affected part, it is necessary to provide other parts such as a bandage, a band, and a tape. The cover sheet has this function.
[0022]
The cover sheet is not required to transmit ultraviolet rays. However, when the cover sheet is formed of a film, at least the covering portion is punched so as to be breathable so that the affected portion does not get steamed.
[0023]
In the case of having a cover sheet, the ultraviolet radiation function and the photocatalytic function of the covering part can be separated and formed on the ultraviolet radiation layer on the cover sheet side and the photocatalytic functional layer that becomes the skin or mucous membrane sticking part. The ultraviolet radiation layer is a layer formed by a woven fabric carrying the phosphorescent ultraviolet radiator or the spontaneous ultraviolet radiator or a film kneaded with these radiators, and the photocatalytic functional layer is a photocatalyst such as TiO2. It is a layer of paste in which a photocatalytic semiconductor is kneaded into a woven fabric, a film or a substrate that is harmless to the human body and is viscous. Except in the case of paste, the ultraviolet radiation layer and the photocatalytic semiconductor layer are integrated with, for example, a vinyl acetate emulsion-based adhesive as necessary.
[0024]
With this configuration, since the ultraviolet radiation layer and the photocatalytic functional layer are separated, each layer has only to be created independently, and the respective functions are not affected by the mutual influence at the time of creation. In addition, phosphorescent ultraviolet emitters and spontaneous ultraviolet emitters are still expensive and when disposable is uneconomical, the ultraviolet radiation layer and the photocatalytic semiconductor layer are not integrated, and the cover sheet and the ultraviolet radiation layer are not integrated. The photocatalytic semiconductor layer can be exchangeable. The fiber sheet constituting the photocatalytic semiconductor layer is, in principle, disposable in terms of hygiene, but it can be washed and reused as necessary for those used for the protection of medical devices.
[0025]
In the case of having a cover sheet, the covering portion can be a pasty coexisting layer in which both the ultraviolet emitter and the photocatalytic semiconductor are kneaded into a viscous base material. Manufacture is easy and the thickness of the covering portion can be reduced. The thickness of the coexistence layer is about 500 μm.
[0026]
In any of the sterilization patch sheets using these cover sheets, an ultraviolet reflection layer may be provided on the opposite side of the covering portion to the human body. As described above, the ultraviolet reflecting layer is formed of a metal foil such as aluminum, or a metal directly deposited on a film or sheet material on which these metals are deposited. In the covering portion, the ultraviolet rays supplied by the ultraviolet radiator can be used efficiently, and the sterilization performance by the photocatalytic function is improved.
[0027]
In the sterilization sticking sheet using a cover sheet, an adhesive part may be further formed at a position in contact with the human body on the inner surface of the cover sheet. The adhesive portion is a portion where a pressure sensitive adhesive mainly composed of synthetic rubber or natural rubber is applied, and has no particular effect on the skin for a short period. This structure is adopted for a small sterilization sticking sheet, and separate paper is stuck on the entire surface including the adhesive part or the covering part. It is convenient to carry and effective for first aid treatment of small wounds on limbs. The separate paper is preferably made of a material transparent to ultraviolet rays so that ultraviolet rays can be easily applied to the ultraviolet radiator from the outside.
[0028]
In addition, in the sterilization sticking sheet using a cover sheet, the ultraviolet reflecting layer may basically be provided in the region of the covering portion, but may be in a wider range. In some cases, aluminum may be deposited on the entire back surface of the cover sheet material to provide a reflective surface.
[0029]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a sterilization sticking sheet 1 of a type to be wrapped and used in the first example. The entire 30 cm × 50 cm cotton woven fabric 2 (sheet material) is immersed in “TO sol”, and after excess sol is squeezed out, it is placed in an oven at about 80 ° C. for 10 minutes, dried and fixed with photocatalytic semiconductor particles 3.

The cover sheet 6 is a strong material made of a polyethylene sheet having a thickness of 30 μm, a width of 20 cm and a length of 60 cm. The covering portion 7 is 20 cm × 20 cm and is relatively large, and is disposed in the substantially central portion of the cover sheet 6, and uses a polyolefin-based porous net as the sheet material 2, but has the same structure as the sterilized patch sheet shown in Example 3 Have That is, it has a photocatalytic function, an ultraviolet radiation function, and an ultraviolet reflection function. The covering portion 7 is fixed to the inner surface of the cover sheet 6 with an adhesive. In this example, the ultraviolet reflecting layer 5 of the aluminum foil is only the region of the covering portion 7, but it may be larger than this region, and the reflecting layer 5 is formed on the entire inner surface of the cover sheet 6 by means of aluminum vapor deposition means. May be.
Reference numeral 8 denotes a vent hole, which is provided on the entire surface of the cover portion of the cover sheet 6.

The photocatalytic functional layer 9 is in contact with the affected area, and the photocatalytic semiconductor particles contained in this layer are in contact with the affected area. These particles are excited by the ultraviolet rays received from the ultraviolet radiation layer 10 on the outside thereof, and perform a bactericidal action.
An anti-inflammatory agent or antibiotic can also be kneaded into the paste of the photocatalytic function layer 9.
[0040]
FIG. 6 is a sixth example similar to the fifth example, but is configured as a coexistence layer 11 in which the photocatalytic semiconductor and the ultraviolet emitter coexist in one layer in the covering portion 7. The ultraviolet emitter is previously mixed in a flexible resin, and the photocatalytic semiconductor is fixed to the surface of the resin forming the layer by coating or pressure bonding. This is one of the coexistence forms of an ultraviolet emitter and a photocatalytic semiconductor. The usage is substantially the same as in the fifth example, but the overall thickness is small and the flexibility is high.
