Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a care mat, and more particularly to a mat suitable for a bed mat of a long-term care worker.
[0002]
[Prior art]
Beds and underlay mats have been developed to prevent wrinkles easily for long-term care recipients in bed. For example, a water bet is said to be less susceptible to wrinkles because the weight of the caregiver is evenly distributed throughout the body and the weight is not concentrated locally. In addition, a double raschel warp knitted fabric having a three-dimensional network structure is highly air permeable, so that it is difficult for wrinkles to occur due to stuffiness. Alternatively, mats laminated with far-infrared rays or magnetic field radiation materials are effective in preventing sputum because their electromagnetic waves promote blood circulation.
[0003]
[Problems to be solved by the invention]
Spiders are stimulated not only by weight concentration, sweating, or stuffiness, but also by fungi that frequently use waste from incontinence and dirt as a nutrient source. However, these points are not taken into consideration in conventional bets and mats. For example, a water bed has a waterproof structure, so that it is easy to cause phlegm due to stuffiness, is expensive and large as a device, is not easy to clean, and cannot be used simply. Double raschel warp knitted fabric is highly breathable and difficult to stuffy, but does not disperse body weight throughout the body. And in the mat | matte which laminated | stacked far-infrared rays and the magnetic field radiation | emission material, the wrinkle by a stuffiness occurs easily.
[0004]
OBJECT OF THE INVENTION
Therefore, the present invention can always be kept hygienic, fungi do not easily propagate, there is no odor from waste products attached due to sweating, incontinence, dirt, etc. The purpose is to obtain a care mat that is rich in nature and does not give a feeling of stuffiness and is effective in preventing wrinkles.

A non-woven fabric 17 having antibacterial and deodorizing properties may be interposed between the double raschel warp knitted fabric 10 and the far infrared radiation fabric 13. The antibacterial and deodorant nonwoven fabric 17 is composed of water-containing oxalic acid compounds such as sepiolite, silotile, rafrinite, falconite, and palygorsite containing antibacterial metal ions such as silver ions, zinc ions, and tin ions, and water of zirconium and cerium. It can be constituted by a synthetic fiber in which an antibacterial mineral powder such as oxide, alumina, aragonite, zinc oxide, titanium oxide, magnesium oxide, zeolite, serpentine, and amphibolite is kneaded. Further, the antibacterial and deodorant nonwoven fabric 17 is composed of these antibacterial mineral powders, 3-4-4′-trichlorocarbanilide, dimethyl adipate, diethyl adipate, diisobutiadipate, dimethyl fumarate, diisobutyl fumarate, 2- 4-4-trichloro-2'-hydroxyphenyl ether, 2-2'-methylenebis (3-4-4'-trichlorophenol), 2-2'-bisthio-4-6-dichlorophenol, α-bromocin An antibacterial deodorant compound such as a namic aldehyde, a carboxyphthalocyanine metal complex, ferrous-L-ascorbic acid, or an amide phosphazene compound may be applied to the nonwoven fabric together with a binder. Preferably, the antibacterial and deodorant nonwoven fabric 17 in which monovalent copper ions are adsorbed on the nonwoven fabric (17) and treated with an aqueous thiosulfate ion solution to convert the monovalent copper ions into copper sulfide is used.
[0014]
An antibacterial fabric 15 may be overlaid on the far infrared radiation fabric 13. The antibacterial fabric 15 is configured in the same manner as the antibacterial deodorant nonwoven fabric 17 described above. That is, since the mineral, copper sulfide, and the like have an antibacterial function and a deodorizing function, they can be applied to both the deodorant nonwoven fabric 17 and the antibacterial fabric 15 that are superimposed on the upper and lower sides of the far-infrared radiation fabric 13. It can also be applied to the double raschel warp knitted fabric 10 and the far-infrared radiating fabric 13, and when the overlay fabric 16 is superposed on the antibacterial fabric 15 for both surface protection and decoration, The present invention can also be applied to the overlay fabric 16.
[0015]
These fabrics (10, 13, 15, 17, 16) are made of synthetic fibers, preferably original synthetic fibers, in particular, low hygroscopic polyester fibers or polyolefin fibers, and air permeability (JIS-L-1018). Is adjusted to 10 cc / cm ² / sec or more. A quilting sewing machine is used for stitching by the perforated line 18 and the sewing machine is applied at regular intervals over the entire surface of the overlapped fabrics (10, 13, 15, 17, 16).

【The invention's effect】
The far-infrared radioactive material emits far-infrared rays that are heated to 30 ° C. or more depending on body temperature, which penetrates to a depth of 40 to 50 cm in the skin, promotes the body's ionization action, activates cells, and promotes blood circulation. Acupuncture is prevented. In the care mat of the present invention, when it is used as an underlay mat for a care bed, the part where the weight is concentrated and wrinkles are generated is in close contact with the far-infrared radioactive material, and the far-infrared ray The coating film (14) of the paint containing the radioactive mineral powder forms fine undulations corresponding to the fabric of the fabric 13, and the surface area of the coating film (14) is increased by the undulations. The rate increases, far infrared rays act strongly, and the effect of wrinkle prevention increases.
[0017]
In the care mat of the present invention, a double raschel warp knitted fabric 10 having a large gap and abundant breathability and cushioning properties is interposed under the far-infrared radiation fabric 13, and the laminated fabric (10, 13, 15, 17, Since the perforated line 18 for stitching 16) forms a vent hole penetrating up and down the care mat, high air permeability is ensured throughout the care mat. Further, in the present invention, the far-infrared radioactive substance-containing paint 14 is partially applied, so that the air permeability of the entire nursing care mat is not hindered, and steaming and wrinkles are promoted using the nursing care mat. There is nothing wrong. And even if the double raschel warp knitted fabric 10 gives a feeling of unevenness due to the difference in thickness due to the presence of the connecting yarns connecting the upper and lower knitted fabrics 11 and 12 in a net shape, the surface Since the (upper side) is covered with the far-infrared radiation fabric 13, overlay fabric 16, antibacterial fabric 15, and deodorant nonwoven fabric 17, the concavo-convex sensation is felt as being finely dispersed throughout the care mat, lying down During use, a moderate feeling of acupressure is transmitted from the care mat to promote a good night's sleep.
[0018]
Furthermore, nursing mats composed of polyester fibers and polyolefin fibers can be quickly dried after washing, and nursing mats composed of synthetic fibers with the original synthetic fibers and antibacterial / deodorant components inside. Dye and antibacterial / deodorant do not directly touch or ooze the skin, and on the care mat with antibacterial deodorant fabric (15/17), micro-organisms such as fungi and mites propagate. Always kept clean. As described above, according to the present invention, a nursing mat that is effective in preventing wrinkles and is suitable for a bed sheet for a nursing bed is obtained.
