The present invention relates to a fever-heating mattress for medical assistance, and more particularly, to a fever-heating mattress for applying direct current power to keep the mattress warm.

In general, the electric bedding for thermal insulation is nitric wire is generally used due to the characteristics that it does not oxidize well at high temperature, is resistant to corrosion, has good workability, and maintains shape well. However, when producing bedding using the existing nichrome wire, because of the characteristics of the bedding or cushioning material is common, such electric bedding has a problem of low flexibility and durability.

And due to the nature of the nichrome wire is installed at a wide interval when installed inside the mattress for insulation, there is a problem that a lot of power to be applied for the insulation due to the wide interval arrangement.

 In addition, since a high voltage AC power is directly used as an applied power supply, there is a risk of an electric shock, an electric leakage or an electric shock caused by an induced current. And when the mattress is overheated during the heating process there is a problem in terms of safety because there is no separate control device.

In order to achieve this purpose, the present invention improves flexibility and durability due to bending by installing a filamentary heating element made of filamentary heating yarn in place of nichrome wire, and by applying a low voltage DC power supply, a short circuit, an electric shock, or an induction current is applied. It is to provide a fever heat insulating mattress to prevent adverse effects on the body.

In order to achieve the above object, the present invention provides a transformer 50 for converting and applying an AC power source to a DC power source, a filamentary heating yarn 24 for generating heat by using an applied DC power source, and the filamentary heating yarn 24. Copper wire spaced at predetermined intervals for applying power to the weft yarn 20 consisting of the first auxiliary yarn 22 positioned between the filamentous heat generating yarns 24 so as to be spaced at a predetermined interval, and the filamentary heat generating yarn 24. It characterized in that it comprises a filamentary heating element (10) consisting of a slope (30) with a built-in (32), a mattress (40) in which the filamentary heating element (10) is embedded, and a temperature controller (70).

Hereinafter, with reference to the accompanying drawings will be described in detail the preferred embodiment of the present invention.

1 shows the filamentary heating element 10 mounted on the thermal insulation mattress 40 and serves to generate heat. The filamentary heating element 10 is a warp yarn 30 having a weft yarn 20 including filamentary heat yarns 24 arranged at predetermined intervals and a copper wire 32 plated with tin to which power is applied at predetermined intervals. It is composed of

The filamentary heating yarn 24 of the weft yarn 20 of the present invention is a filamentary heating yarn 24 having a predetermined resistance value made by coating a resin suspension prepared by mixing a synthetic resin solution with natural fibers or synthetic fibers. At this time, the natural fiber or synthetic fiber used as a heating element, it is preferable to use a thermoplastic resin of the synthetic fiber to maintain a stable physical state for a long time. This is because the thermoplastic resin has good heat resistance and low moisture resistance, and therefore has good chemical resistance and acts as a fuse to cut off power when melting at a certain temperature.

In the filamentary heating element 10 of the present invention, the filamentary heating yarn 24 is capable of high temperature heat generation with high heat radiation efficiency, and there is no fear of overheating due to constant temperature heat generation. . That is, in the case of the filamentary heating element 10 made of carbon heating yarn, far infrared rays which are beneficial to the human body are generated, and the emissivity was found to be 0.883 at 60 ° C.

The copper wire 32 of the inclination 30 of the present invention allows power to be applied to the filamentary heating yarn 24 having a constant resistance. Since tin serves to prevent oxidation and corrosion of the metal, it is preferable to use copper plated with tin.

2A and 2B show the filamentary heating element 10 viewed from the side and the front, respectively.

The filamentary heat generating yarn 24 is preferably arranged in parallel. This is because when the filamentary heating yarns 24 are arranged in series, the thermal insulation function of the entire mattress is lost when any part of the short circuit occurs. That is, arranging the filamentary heating yarns 24 in a parallel form in parallel so as not to affect other heating lines when a short circuit occurs in any one portion.

Accordingly, as shown in FIG. 2A, the weft yarns 20 arranged in the horizontal direction of the filamentary heating element 10 have a first auxiliary yarn 22 coupled between the filamentary heat yarns 24 arranged in parallel to each other. 24) are woven to maintain a constant interval. At this time, the spacing of the fever heat yarn 24 is adjusted in consideration of the area of the mattress, the power consumption. In addition, when the weaving spacing of the filamentary heating yarn 24 becomes dense, the heat distribution is even, and the maximum heat generating effect can be achieved with less power.

2B illustrates an arrangement state of the inclination 30 arranged in the vertical direction of the filamentary heating element 10. The second auxiliary yarn 34 of the inclination 30 serves to fix the weft yarn 20 formed of the filamentary heating yarn 24 and the first auxiliary yarn 22. This function of the inclination 30 is preferably arranged on the upper and lower surfaces of the weft yarn 20. In addition, as shown in FIG. 1, the weft yarn 20 and the warp yarn 30 may be woven in any form as long as they maintain the function of the second auxiliary yarn as well as the vertical weave.

It is preferable to use polyester yarn which is excellent in heat resistance as said 1st auxiliary yarn 22 and the 2nd auxiliary yarn 34. As shown in FIG. If the heat resistance is low, it is impossible to fix the filamentary heat yarn at a constant interval, that is, not to be parallel, so that a uniform temperature distribution cannot be expected.

The filamentary heating element 10 manufactured as described above is preferably coated with an insulator 90 for insulation on both sides.

4 shows a state after wiring to the filamentary heating element 10. A low voltage DC power supply (for example, DC 24V) is applied to the power supply unit 35, and the effect of the electromagnetic field can be reduced by applying the DC power supply. Electromagnetic fields can adversely affect the body, particularly those sensitive to the external environment, such as patients. Therefore, by applying the low-voltage DC power supply of the present invention, it is possible to protect the body from electromagnetic fields and to cope safely in case of short circuit or electric shock.

In this case, the copper wire part 32 is preferably connected to one end of the first copper wire 41 and the third copper wire by a negative pole (-pole) when one end of the first copper wire 41 and the third copper wire are connected to the positive pole (+ pole). Do. Since the flow of current is opposite to each other, the direction of the magnetic field and the electric field formed around the first copper wire 41, the second copper wire 42, and the third copper wire 43 are reversed to each other, and the effect is canceled. Therefore, in addition to the effect of applying the DC power source can be expected to reduce the emission of electromagnetic waves separately.

Figure 5 shows an embodiment of a fever heating mattress using a DC power source equipped with a filamentary heating element (10). The filamentary heating element 10 is mounted on the marble mattress 40, and then a flame retardant sponge 60 is added. And the mattress cover 80 covers the entire mattress and finishes. The mattress cover 80 may be artificial leather or the like.

 Thereafter, the filamentary heating element 10 is connected to a transformer 50 for converting AC power into DC power, and is equipped with a temperature controller 70 for temperature control.

The temperature controller 70 preferably uses a small and inexpensive thermistor. The temperature controller may be configured to control mainly at 30 ° C to 60 ° C to obtain the effect of heat retention, and if necessary to obtain the effect of heat retention, is also controllable in other temperature ranges.

At this time, in addition to the marble mattress 40, other types of mats can be used in the present invention, as well as the part in contact with the body is any material that can withstand heat generated from the filamentary heating element 10 in addition to the flame retardant sponge 60. It is obvious that also possible.

In addition, the electric bedding according to the present invention can be used not only when used for medical purposes, but also as a mat for a driver traveling for a long time.

As described in detail above, the filamentary heat insulating mattress having a filamentary heating element and a DC power source according to the present invention has an advantage of excellent flexibility and flexibility. And it does not need to remove the mattress and put the heating element has the advantage of convenience in terms of production.

In particular, the use of the carbon heating element has the effect of exposing patients to far infrared rays as well as the warming effect. In addition, by applying a DC power source instead of a normal high-voltage AC power supply to prevent the generation of induction current, by using a low voltage (for example, DC 24V) to protect the patient from the risk of electric shock or short-circuit, it is difficult to respond immediately in case of emergency It is particularly useful for patients.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it will be readily apparent to those skilled in the art that various other modifications and variations are possible without departing from the spirit and scope of the present invention. All belong to the scope of the utility model claims attached.
