Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gauze for protecting wounds such as burns and trauma from bacterial infection, clothing for preventing infection, underwear, socks, gloves, etc. The present invention relates to a silver fiber woven body used for an adhesive bandage, a bandage, a mask, a shime, and the like.

[0002]

2. Description of the Related Art Conventionally, gauze used for medical treatment as in the above-mentioned example is made of fine ceramics impregnated with a bactericide or having silver ions attached thereto in order to prevent bacteria from growing on the gauze itself. There is a gauze knitted by kneading particles into fibers.

[0003]

However, since the above-mentioned gauze is mounted in close contact with the wound of a patient, the skin tissue to be regenerated bites into the fiber of the gauze, and when the gauze is replaced, the skin tissue is regenerated. Because of the exfoliation along with the gauze, the wound often bleeds, slowing healing. In addition, there is a problem that pain is given to the patient every time the gauze is peeled off.

[0004] Gauze absorbs body fluids (eg, blood) oozing from the wound, so that the nutrients can be used as a source of nutrients to grow bacteria, so that suppuration often occurs in the wounds, resulting in foul odors. The gauze must be changed regularly, as this will cause it. In addition, when the gauze is used many times, the gauze must be sterilized and disinfected each time, so that it is troublesome.

[0005] In the case of sterilization without using gauze, there is a method of spraying a bactericide (spray type) onto the wound to sterilize the wound. However, since the wound surface is covered with the bactericide and the wound is fixed, the wound is internally fixed. The infection can progress and sometimes become severe.

[0006] When a disinfectant is used, a temporary bactericidal effect can be obtained, but it is not persistent and the bactericidal effect is immediately reduced, so that reinfection cannot be prevented.

In view of the above problems, the present invention attaches a woven material in which silver fibers are woven to an arbitrary portion, so that the woven material itself and the portion to which the woven material is attached are sterilized, and the growth of bacteria can be suppressed. . Further, it is an object of the present invention to provide a silver fiber woven body capable of obtaining a bactericidal action and an antibacterial action for a long period of time.

[0008]

According to the first aspect of the present invention,
It is a silver fiber woven body formed by knitting a yarn made of silver fibers in an arbitrary ratio into a woven material knitted in an arbitrary weave.

According to a second aspect of the present invention, in addition to the first aspect, the silver fiber woven body is a silver fiber woven body in which the yarn made of the silver fiber is used for a warp and / or a weft constituting the woven fabric. Features.

According to a third aspect of the present invention, in addition to the first or second aspect, the silver fiber is a silver fiber woven body formed by coating an arbitrary fiber surface with silver plating. And

[0011] The invention described in claim 4 is the first and second claims.
Or, in combination with the constitution described in 3, a silver fiber woven body knitted with the silver fiber and a yarn obtained by twisting an arbitrary fiber is characterized.

[0012] The fifth aspect of the present invention is directed to the first and second aspects.
Or in combination with the configuration of 3, a yarn made of the silver fiber,
It is characterized by being a silver fiber woven body formed by knitting yarns of arbitrary fibers by twisting.

According to a sixth aspect of the present invention, in addition to the configuration of the first aspect, the woven fabric is a silver fiber woven body formed by knitting yarns made of chemical fibers.

[0014]

According to the silver fiber woven body of the first aspect, since the yarn made of silver fiber is woven into a woven fabric knitted in an arbitrary weave, the woven fabric itself and the woven fabric are attached by the sterilizing action and the antibacterial action of silver itself. The part is sterilized, the growth of bacteria can be suppressed, and a clean and sanitary state can be maintained.

In the woven silver fiber body according to the second aspect, the yarn made of silver fiber is used for the warp and / or the weft in addition to the operation of the first aspect. Therefore, the number, interval, and thickness of the yarn ( By changing the denier, and weaving it to an arbitrary density and area, the effect of the silver fiber can be set to an arbitrary strength, and the area and portion where the effect is exerted can be arbitrarily set.

In the silver fiber woven body according to the third aspect, silver fibers are formed by silver plating coating of arbitrary fibers (for example, chemical fibers) in addition to the function of the first or second aspect. Has a strong fixing force and is hard to peel off, so that a bactericidal action and an antibacterial action can be obtained for a long period of time.

According to the fourth aspect of the present invention, the silver fiber woven body is knitted by a silver fiber and a yarn obtained by twisting an arbitrary fiber together with the operation of the first, second or third aspect. The bending strength and the tensile strength are increased, and the durability of the woven fabric is improved.

According to the fifth aspect of the present invention, the silver fiber woven body is knitted by a yarn obtained by alternately twisting a yarn made of a silver fiber and a yarn made of an arbitrary fiber, in addition to the operation of the first, second or third aspect. Therefore, the bending strength and the tensile strength are increased, the durability of the woven fabric is improved, and the silver fibers are exposed, so that the same effect as when only the silver fibers are woven is obtained.

In the silver fiber woven body according to the sixth aspect, since the woven fabric is knitted by the yarn made of the water-repellent chemical fiber in combination with the configuration according to the first aspect, it hardly absorbs moisture, Since the rate is low, the liquid exuding from, for example, a wound (wound) does not penetrate, and the exfoliation exchange can be easily performed.

[0020]

According to the present invention, the woven material in which the silver fibers are woven is mounted on an arbitrary portion, so that the germ itself and the portion on which the woven material is mounted are sterilized by the sterilizing action and the antibacterial action of silver itself. Since the growth of bacteria is suppressed, it is possible to maintain a clean and hygienic condition, for example, to prevent the wound healing from being delayed by bacterial infection and to regenerate the skin tissue so that scars do not remain. it can.

Moreover, the growth of bacteria is suppressed by the sterilizing effect and catalytic effect of silver itself, and odor elements such as sweat and body odor are decomposed, thereby preventing generation of bad odor. A comfortable environment is obtained without causing discomfort to surrounding people.

Silver has the highest conductivity among metals and suppresses the amount of static electricity charged during use. Therefore, body potential can be adjusted, activation of body functions is promoted, and skin tissue is activated. It can promote regeneration and healing.

Further, since the yarn made of silver fiber is used for the warp and / or weft, the number, interval and thickness of the yarns are changed to be woven into an arbitrary density and area, so that the effect of the silver fiber can be adjusted to an arbitrary value. The strength can be set, and the area and portion where the effect is exhibited can be set arbitrarily.

Furthermore, since silver fibers coated with silver plating are used, the antibacterial agent has a stronger adhesion to silver and is harder to peel off than post-processing or kneading the antibacterial agent as in the conventional example. Even if the laundry is washed, the effect of the silver fiber is not deteriorated or reduced, and the bactericidal effect and the antibacterial effect can be obtained for a long time.

Furthermore, since a yarn formed by twisting a silver fiber and another fiber or a yarn formed by alternately twisting a silver yarn made of a silver fiber and a yarn made of another fiber is used, the bending strength and tensile strength of the silver fiber are increased. The strength is increased, and the durability of the woven silver fiber body is improved.

Further, a chemical fiber having water repellency,
Since it is knitted by a thread made of silver fiber having a bactericidal effect, the area of contact with the skin of the wound is smaller than that of the conventional cotton gauze, and it does not absorb liquids such as moisture and body fluids. Is not soaked in the fiber, the peeling and replacement of the silver fiber woven body can be easily performed, and the pain given to the user can be reduced.

The warp yarn 11 includes natural fibers (for example, cotton fibers,
Hemp fibers, wool fibers, silk fibers or other natural fibers) are used, but for example, yarns obtained by twisting chemical fibers may be used. You may use the thread which mixes or mixes at a ratio and twists.

The weft yarn 12 is composed of a silver fiber 13 of about 40 denier obtained by coating a chemical fiber (for example, nylon fiber) with silver plating, and another chemical fiber (for example, polypropylene fiber, polyester fiber or other chemical fiber). A yarn obtained by twisting the fibers 14 of about 100 denier at an arbitrary ratio and ratio is used. For example, a yarn obtained by twisting the same chemical fiber may be used.

Further, a yarn obtained by mixing or compounding silver fibers 13 made of chemical fibers and fibers 14 made of natural fibers at an arbitrary ratio and twisting them may be used.

The silver fibers 13 are formed as shown in FIGS.
The entire surface of the nylon fiber 13a formed into an arbitrary cross-sectional shape (for example, a cross-sectional shape such as a round shape, an ellipse, and a flat shape) is uniformly plated with silver 13b having an arbitrary purity (for example, 100% purity) (for example, by applying, coating). Vapor deposition etc.)
Then, the yarn is twisted to an arbitrary thickness (for example, about 30 denier to about 40 denier). The silver fibers 13 and the fibers 14
May be changed to an arbitrary ratio and an arbitrary thickness (denier).

In the embodiment, the silver fiber woven body 10 is knitted by a plain weaving method, but knitted by other weaving methods (for example, lattice weave, twill weave, satin weave, entangled weave, pile weave, non-woven). Also, any knitting method (for example, mirrors knitting,
The knitting may be performed by a vertical knitting such as a cord knitting, an atlas knitting, a tricot knitting, or a horizontal knitting knitting such as a pearl knit, a tack knitting, a double-sided knitting, a floating knitting, a lace knitting, and a perrin knitting.

When knitting the silver fiber woven body 10 described above, the warp yarn 11 formed by twisting natural fibers and / or chemical fibers is used.

Weft yarns 12 formed by twisting silver fibers 13 and fibers 14 are woven in parallel to the horizontal direction at predetermined intervals, and the warp yarns 11 are formed.
And the weft yarns 12 are knitted in an open gauze shape at an arbitrary interval. The warp 11 and the weft 12
May be changed to an arbitrary weaving interval and the number of weaving.

With respect to the total weight of the silver fiber woven body 10,
By weaving the silver fiber 13 coated with silver plating in the range of about 10 wt% to about 20 wt%, inflammation due to bacterial infection can be prevented. The silver fibers 13 may be changed to an arbitrary weaving amount (weight ratio = wt%).

Since the weft 12 formed by twisting the silver fibers 13 and the fibers 14 is uniformly woven in the silver fiber woven body 10, the bactericidal effect and the antibacterial effect of the silver fibers 13 are reduced to the wound of the patient. Can be applied uniformly.

The silver fiber 13 may be woven into an arbitrary portion of the silver fiber woven body 10, and the effect of the silver fiber 13 can be given to a specific portion.

The warp yarn 11 constituting the silver fiber woven body 10 may be a yarn formed by twisting a chemical fiber and / or a natural fiber, a yarn formed by twisting silver fibers 13 and 14, or a silver fiber 13. Alternatively, only a yarn formed by twisting the fibers 14 or the yarn formed by twisting the silver fibers 13 may be used.

The weft yarn 12 has silver fibers 13 and fibers 14
May be woven alternately (for example, every other one) at an arbitrary number and at an interval using a yarn formed by twisting a chemical fiber and / or a natural fiber.

In the above embodiment, the silver fiber woven body 10
As the warp yarn 11 and the weft yarn 12 constituting the yarn, a yarn formed by twisting silver fibers 13 and fibers 14 is used. As shown in FIGS. 6 (a) and 6 (b), the silver fibers 13 and fibers 14 are twisted. It is also possible to use a yarn obtained by cross-twisting (spirally winding) a core yarn 16 formed by twisting a chemical fiber and / or a natural fiber with the silver yarn 15 formed as described above.

The silver yarn 15 is made of silver fiber 13 coated with silver plating, and a fiber 1 made of chemical fiber and / or natural fiber.
4 may be used, and silver fiber 13 may be used.
May be used alone.

In the embodiment, the silver yarn 15 is wound around the core yarn 16 and twisted. Alternatively, a yarn made of a chemical fiber or a natural fiber may be wound around the silver yarn 15 and twisted. The twisting may be performed by other twisting methods (for example, twine yarn, wall yarn, helical yarn, sabori yarn, chain yarn, curl yarn, etc.).

The warp yarn 11 and / or the weft yarn 12 may be used in combination with a yarn formed by twisting silver fibers 13 and fibers 14 and a yarn formed by alternately twisting silver yarn 15 and core yarn 16. May be changed to an arbitrary weaving interval and the number of weaving.

Instead of the above-mentioned chemical fibers, chemical fibers made of synthetic resin such as rayon, cupra, acetate, vinylon, vinylidene, polyvinyl chloride, acrylic, polyethylene, polyurethane, or cotton,
Natural fibers such as cotton, hemp, wool, and silk may be used, or fibers obtained by compounding or mixing chemical fibers and natural fibers may be used.

The illustrated embodiment is configured as described above, and the silver fiber woven body 10 is hereinafter referred to as the abdomen Aa of the patient A,
The state of being attached to the arm Ab will be described. First, as shown in FIG. 7, when the silver fiber woven body 10 is mounted on a wound (for example, a burn or a wound) formed on the abdomen Aa and the arm Ab of the patient A, the size and shape of the wound are covered. The silver fiber woven body 10 and the patient A are attached by separating (cutting) and mounting the silver fiber woven body 10 formed in a predetermined size, and by the sterilizing action and antibacterial action of silver itself.
Wounds are sterilized, bacterial growth can be suppressed, and a clean and hygienic condition can be maintained.

The woven silver fiber body 10 may be fixed (for example, bandage, string, hook-and-loop fastener, etc.) so that the wound formed on the abdomen Aa and the arm Ab is covered. The patient A may be attached to a wound formed on another body part (for example, a head, a back, a foot, a waist, a finger, etc.) of the patient A except for the abdomen Aa and the arm Ab. The same operation and effect as those described above can be obtained.

Since the silver fiber 13 has a high conductivity, the silver fiber woven body 10 is attached to a wound (eg, a burn or a wound) of the patient A, and then a weak pulse current supplied from a current supply device (not shown). Is applied to the silver fiber woven body 10, activation of body functions is promoted, and regeneration and healing of skin tissue can be promoted.

As shown in FIG. 8, a silver fiber woven body 10 knitted in a band shape is folded and loaded on a mouthpiece Ba (filter part) constituting a mask B for preventing infection, or a predetermined size. After the silver fiber woven bodies 10 are formed in a stack, the mask B loaded with the silver fiber woven bodies 10 is mounted so that the mouth and nose of the user are covered, Since the straps Bb attached to the both side edges of the abutting portion Ba are used by hanging the ears of the user, the mask B
By sucking in through the silver fiber woven body 10 loaded in the mouthpiece Ba of the above, the bacteria floating in the air are sterilized by the silver fibers 13 woven into the silver fiber woven body 10, and the user can remove the bacteria from the bacteria. Infection can be reliably prevented.

Further, since the breath is exhausted from the mouth and nose of the user via the silver fiber woven body 10 loaded in the mouthpiece Ba of the mask B, the silver woven in the silver fiber woven body 10 is exhausted. Bacteria contained in breath are sterilized by the fibers 13, and it is possible to reliably prevent a person other than the user from being infected with the bacteria. Note that the entire mask B may be formed of the silver fiber woven body 10.

As a comparative example of the test piece A in which the silver fiber 13 is woven as described above and the test piece B knitted only with the cotton fiber,
Test the bactericidal effect over time against pathogenic E. coli or other bacteria under the same conditions.

As a test method, a test bacterium was inoculated on a normal agar medium and cultured at about 37 ° C. for about 24 hours.
The colony is inoculated into a normal broth medium and cultured at about 37 ° C for about 16
Incubate for about 18 hours to about 18 hours. In addition, all the bacteria cultured in the ordinary broth medium are adjusted to 108 cfu / ml.

When preparing a specimen, the specimen and the test pieces A and B (squares each having a side of about 20 mm) are placed in a petri dish and sterilized by high-pressure steam.

In the test operation, a specimen and test pieces A and B were set as a set, and 100 μl of the test bacterial culture was impregnated into all test pieces A and B, and the test pieces were chronologically (eg, 5, 1).
0, 15, 20, 30, 45, 60, 120, 180,
Every 240 minutes), the number of bacteria in test pieces A and B is measured.

When measuring the viable cell count, 1 ml of a sterilization buffer is added to a sterilization test tube containing the sample, and about 3 ml is added to the mixture using a blender.
After stirring for 0 second, the bacteria present in the test pieces A and B were extracted. 100 μl of this extract is inoculated on a normal agar medium,
As a result of culturing at about 37 degrees for about 24 hours to about 48 hours and measuring the number of viable cells, a test result as shown in FIG. 9 is obtained. Since the woven test piece A requires a shorter time for sterilization and the number of bacteria decreases in a short time, it is clear that the silver fiber woven body 10 has more excellent sterilizing and antibacterial effects. Also,
The same effect as described above can be obtained against Klebsiella pneumoniae, Pseudomonas aeruginosa, staphylococci, fungi and other bacteria.

As described above, since the silver fiber woven body 10 in which the silver fibers 13 are woven is mounted on the wound of the patient A or as the mask B for preventing infection, the bactericidal action of the silver itself and the antibacterial effect By the action, the wound portion of the silver fiber woven body 10 and the wound of the patient A to which the silver fiber woven body 10 is mounted and the intake air are sterilized, the growth of bacteria can be suppressed, and a clean and hygienic state can be maintained. In addition, the healing of the wound can be prevented from being delayed by bacterial infection, and the skin tissue can be regenerated without leaving scars.

Further, the growth of bacteria is suppressed by the sterilizing effect and catalytic effect of silver itself, and odor elements such as sweat and body fluids are decomposed, so that generation of offensive odor can be prevented. A comfortable environment is obtained without causing discomfort to surrounding people.

The silver 13b of the silver fiber 13 has the highest conductivity among metals and suppresses the amount of static electricity charged during use, so that the body potential can be adjusted and the activation of body functions is promoted. It can promote regeneration and healing of skin tissue. In addition, silver 13b is a safe metal with less irritation to the skin than other metals, and thus can be used in medical or other fields.

Further, since the silver fibers 13 always release a small amount of silver ions on the wound surface in a lubricated state, while the silver fiber woven body 10 is mounted on the wound of the patient A,
A bactericidal effect is always provided, and recurrence of inflammation and the like due to re-infection can be prevented.

When used for mild trauma, the time required for healing is shorter than that of a bandage using gauze impregnated with a normal disinfectant, and the wound is healed in a short period of time without frequent replacement.
Further, even if the user takes a bath with the silver fiber woven body 10 attached, the germicidal effect of the silver fibers 13 is not deteriorated or reduced, and the bacteria are not infected.

Further, since a yarn formed by twisting silver fibers 13 and fibers 14 or a yarn formed by alternately twisting silver yarn 15 and core yarn 16 is used, the number, interval and thickness of the yarns are changed. By weaving into an arbitrary density and area, the effect of the silver fiber 13 can be set to an arbitrary strength, and the area and portion where the effect is exerted can be arbitrarily set according to the application and the situation.

Furthermore, since the silver fiber 13 coated with silver plating is woven, the adhesive strength of silver is stronger than that of post-processing or kneading the antibacterial agent as in the conventional example.
Because it is difficult to peel off, the effect of the silver fiber 13 does not deteriorate or decrease even after washing many times (for example, about 50 times).
The effect is maintained for a long time or semi-permanently, and there is no need to perform a sterilization treatment as in the conventional example, and the frequency of replacement can be reduced.

Further, the warp 11 and / or the weft 12
And a yarn or silver yarn 5 formed by twisting silver fibers 13 and 14
Since the yarn formed by twisting the core yarn 6 and the core yarn 6 is used, the bending strength and the tensile strength of the silver fiber 13 are increased, and the durability of the silver fiber woven body 10 is improved.

Further, a chemical fiber having water repellency,
Since the knitting is performed using the silver fibers 13 having a bactericidal effect, the contact area with the hygroscopic fibers in contact with the skin is reduced to about half (for example, about 50%) as compared with the cotton gauze as in the conventional example. The fiber woven body 13 can be easily peeled and replaced,
The pain given to the patient A can be reduced.

Further, since the knitting is performed using the warp yarns 11 and the weft yarns 12 made of chemical fibers, the air permeability is better than that of cotton gauze, and the time required for drying is about 1/3, so that the handling is easy. .

In the correspondence between the structure of the present invention and the above-described embodiment, the woven fabric of the present invention corresponds to the silver fiber woven body 10 of the embodiment, and similarly, the yarn made of the silver fiber corresponds to the silver fiber 13 Warp 11 and weft 1 obtained by twisting fibers 14
2. Although corresponding to the silver thread 15, the present invention is not limited to only the configuration of the above-described embodiment.

The above-described silver fiber woven body 10 is used to sew, for example, clothing, underwear, socks, gloves, and squeezes for preventing infection, or as a medical tool such as an adhesive plaster or a bandage, or the like. It can also be used for nursing care and nursing of the handicapped, etc., and the application is not limited only to the medical field described above.
