Description

[Detailed Description of the Invention] The present invention relates to a heating pad that is placed on or wrapped around the body to perform heating treatment on affected areas of the body.

FIG. 1 is a perspective view showing a conventional heating pad. FIG. 2 is a cross-sectional view of FIG. 1, and the conventional heating pad has a resin-coated heating wire, ie, a heater 5 like a cord heater, arranged between two sheet members 3 and 4. , sheet member 3,
a heating pad 1 in which a heater 5 is sealed and fixed;
In order to use the heating pad 1 by placing it on or wrapping it around the affected part of the body, it is necessary to make the heating pad 1 stick closely to the body, so on one side of the heating pad 1,
This is to fix the pressure pad 2.

Since the pressure pad 2 applies pressure, a lead plate 6 or a liquid is used to pressurize the heating pad 1 into close contact with the body.
When using a heating pad, although it has flexibility, it is difficult to pressurize the entire surface of the heating pad. In other words, the lead plate 6 cannot be bent unless force is applied to it, and has the disadvantage of poor restorability, and the pressure applied to one surface of the heating pad is not constant, making it difficult to heat the body. There is uneven adhesion of pad 1. In addition, if the lead plate 6 is used instead of a liquid, the liquid is stored in a bag-shaped resin sheet, so when it is placed along the affected part of the body, the liquid moves and applies uniform pressure. If this is not possible and the bag-shaped resin sheet is damaged, there is a risk of liquid leaking.

The heating pad of the present invention is a heating pad devised to eliminate the above-mentioned drawbacks, and FIG. 3 is a perspective view showing an embodiment of the heating pad of the present invention. FIG. 4 is a sectional side view of FIG. 3. FIG. 5 is a plan sectional view of the pressure pad 8.

Referring to the above drawings, a heater 18 such as a cord heater or a heat-generating bare wire is disposed between sheet members 14 and 15 such as a cloth sheet, a waterproof cloth sheet, or a resin sheet. , a heating pad 7 is formed in a sealed manner within the sheet members 14 and 15. In the embodiment, a temperature detection wire 19 is provided along the heater 18, and the lead wire 9 led out from the heating pad 7 is connected to the temperature controller 10, and the power cord 13 is connected from the temperature controller 10. The temperature controller 10 is provided with a temperature control knob 11 and a timer knob 12. The heater 18 of the heating pad 7 is connected to the sheet member 1
4, 15, if the heater 18 is a cloth sheet or a waterproof sheet,
Alternatively, there is a means of sewing and fixing the resin sheet to the sheet members 14 and 1, such as a waterproof sheet.
5, the sheet members 14 and 15, such as vinyl chloride sheets, are welded together using a high frequency welding machine,
A cylindrical space for housing the heater 18 is formed,
Means for arranging and fixing the heater 18 inside the cylindrical space is well known. In the above heating pad 7,
Since the sheet members 14 and 15 and the heater 18 are flexible, they are bendable. On one side of this heating pad 7, a passage 21 is formed between sheet members 16 and 17, such as a cloth sheet, a waterproof sheet, or a resin sheet.
In this passage 21 a pressure pad 8 with a chain-like member 20 is provided. The chain member 20 is, for example, a chain made of a metal material, a ball chain, a plate chain, chain mail, etc., and when the sheet members 16 and 17 are cloth sheets or waterproof cloth sheets,
The passage 21 is formed by stitching, and the sheet members 16, 1 are made of a resin sheet such as a vinyl chloride sheet.
7, the passage 21 is formed by thermal welding and is provided within the passage 21. The chain member 20 is arranged in a chain, and the passage 2
1, or the chain members 20 are disposed intermittently within the passage 21, and the individual chain members 20 are fixed within the passage 21. . The above-mentioned pressure pad 8 has flexibility because the sheet members 16 and 17 and the chain member 20 are bendable.
This pressure pad 8 is provided with a velvet fastener 22 on the surface facing the heating pad 7,
The heating pad 7 and the pressure pad 8 are fixed together by connecting and fixing the heating pad 7, or by using a hook, button, or other locking member.

As described above, in the heating pad of the present invention, when the heater 18 is energized from the power source, the heating pad 7 is heated and the affected part of the body is heated, and at the same time, the pressure pad 8 is moved in the direction of the affected part of the body. , because it is pressurized, it is possible to perform heating treatment on the entire affected part of the body, and as an effect, since the chain member 20 is used, the heating pad 7 can be pressurized on average to the affected part of the body, and after use, Since it is bendable, it is easy to store, and when used again, the pressure pad 8 will not be bent or wrinkled due to bending, and will always be able to pressurize the body in a flexible state. be.

Further, the chain member 20 includes the sheet member 16,
This makes point contact with the inner surface of the heating pad 7, thereby reducing heat conduction from the heating pad 7, and creating an air layer inside the passage 21, which provides a heat insulating effect. Therefore, since the conduction of heat from the heating pad 7 to the pressure pad 8 can be reduced, the temperature of the heating pad 7 can be rapidly increased, and the treatment time can be shortened.
