Description

[Detailed explanation of the invention] A. Purpose of the invention [Field of industrial application] The invention is intended for medical bedding, such as mattresses, comforters, sheets, blankets, pillows, pine tresses, bed pads, and the like. Regarding covers etc.

[Conventional technology]

Traditionally, medical bedding has been made of the same materials as general bedding, such as cotton, silk, etc.
Various natural fibers such as panya, various synthetic fibers such as polyester, such fiber fabrics such as woven fabrics, knitted fabrics, non-woven fabrics, laminates of such fabrics and other sheet materials or layered materials, etc. In many cases, general bedding is used as medical bedding.

[Problem that the invention attempts to solve]

By the way, in recent years, various types of medical equipment (medical equipment, ME equipment) have been highly integrated into electronic circuits, and are capable of processing minute electrical signals, etc.
High-precision products have been developed and are now in use.

However, as such, electrical external noise,
For example, it is susceptible to adverse effects on functionality and accuracy due to static electricity, AC induced hum from power lines, broadcast radio waves, electromagnetic noise from electric scalpels, automobiles, etc.
Therefore, with regard to medical bedding, static electricity and external noise penetration into the bedding have become issues.

For example, bedding made of chemical fibers is particularly susceptible to static electricity, and the electric blanket 4 (Fig. 1) generates strong electromagnetic noise when energized; Patients wearing oscillators, electroencephalogram measurement oscillators, etc. should avoid or cannot use them.

Therefore, regarding medical electric blankets/blankets, insulating treatment is applied to both or one side on the top surface of electric blankets/blankets or in an encircling manner for the purpose of preventing electrical noise from being generated in medical measuring devices such as electrocardiographs when electricity is applied. A structure has been proposed in which a conductor is coated with aluminum foil or copper mesh, and the conductor is grounded.
Publication No.).

However, bedding containing aluminum foil or copper mesh as a constituent material lacks flexibility, lightness, washing resistance, breathability (in the case of aluminum foil), moisture absorption, etc. have a problem

This invention has the same good properties as regular cloth, such as flexibility, lightness, drapability, breathability, moisture and water absorption, feel, washing resistance, and sewing properties, and also has sufficient electromagnetic shielding properties. The purpose of the present invention is to provide medical bedding that is more practical in terms of usability.

B. Structure of the invention [Means for solving the problems] The present invention is based on conductive fibers made by applying metal coating to base fibers such as polyester, or conductive woven fabrics or conductive knitted fabrics using the fibers. , or medical bedding made from conductive nonwoven fabrics.

[Effect]

A very thin metal coating such as nickel (0.01
~0.5 μm) coated conductive fibers or fiber fabrics (woven fabrics, knitted fabrics, non-woven fabrics) have a surface specific electrical resistance of 10 ^-2 to ^{10 6} Ω/□, good antistatic effect (self-discharge property) ), good electromagnetic shielding effect (more than 30 to 40 dB in frequency band 1 MHz to 30 GHz)
has. Therefore, bedding made from such conductive fibers or conductive fabrics is substantially free of static electricity due to the conductivity (self-discharge properties) of the material, and also has a good electromagnetic shielding effect. Therefore, it is possible to use the electronic ME equipment M, which is easily affected by static electricity and electromagnetic noise, without any problem.

In addition, the inherent flexibility, lightness, and drapability of cloth
It has sufficient properties such as breathability, moisture absorption, water absorption, feel, washability, and sewing properties, so it can be used comfortably as bedding, and due to its washability, it can be kept clean at all times.

〔Example〕

Therefore, the present invention uses the above-mentioned conductive fibers or conductive fabrics as stuffing materials, outer covering materials, etc. to create pine mattresses 1, bed pads 2, bed sheets 3, blankets 4, etc.
It constitutes the bedding such as the comforter 5 and the pillow 6, or the covers thereof, thereby making the bedding and cover non-static and electromagnetic shielding.
It also becomes resistant to dust and dirt due to electrostatic action.

Even if the blanket 4 is an electric blanket, by covering it with a cover 7 made of conductive fabric, the electromagnetic noise generated when electricity is applied is well shielded, and the electronic equipment M can be attached and used without problems. becomes. 8 is a discharge wire provided on the blanket cover 7, and is provided as necessary.

The cover 7 of the electric blanket 4 may be configured such that both of the fabrics covering the upper surface side and the lower surface side of the blanket are made of conductive fabric, or only the fabric on the lower surface side may be made of conductive fabric. Further, as shown in the second figure, the fabrics 7a and 7b on the upper and lower sides of the cover 7 are made of cotton fabric, for example, and there is conductivity between the lower side of the electric blanket 4 housed in the cover 7 and the lower fabric 7b of the cover 7. It may also be configured in such a manner that the fabric 7c is interposed therebetween. The periphery of the conductive fabric 7c is sewn to the periphery of the lower fabric 7b of the cover 7.
Alternatively, the surface of the lower fabric 7b may be laminated in advance. 7d is a cover opening/closing chuck portion.

C. Effects of the invention As described above, the bedding of the invention allows electronic ME equipment to be used without problems due to its good electromagnetic shielding properties, and because it has the same cloth characteristics as ordinary cloth. It can be used comfortably at all times, and because of its wash resistance, it can always be used cleanly, making it effective and suitable as medical bedding.
