【発明の詳細な説明】
本発明は腰，肩，腕頭の人体患部に装着して温
熱治療を行なう温熱パツドに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heating pad that is attached to the affected areas of the human body such as the waist, shoulders, and armpits to perform thermal treatment.
一般に、温熱パツドは使用中に汗などの湿気が
発熱体へ侵入することが多く、このため発熱体を
被包し防水することが必要であり、特に発熱体か

水袋５とを高周波溶着して電源コード６の周囲を
密閉していた。 Generally, when using a heating pad, moisture such as sweat often enters the heating element, so it is necessary to encapsulate and waterproof the heating element, especially around the power cord extending from the heating element. It is important to completely seal the power cord 6, and conventionally, as shown in Figs. The periphery of the power cord 6 was sealed by high-frequency welding with the bag 5.
ところが、かかる方法では第１図に斜線で示す

した場合には電源コード６の芯線の絶縁性能が劣
化する危険性があつた。 However, with this method, it is necessary to increase the welding area as shown by diagonal lines in FIG.
In addition, since there is a large difference in the coating thickness of the power cord 6 and the sheet thickness of the waterproof bag 5, the power cord 6 and the waterproof bag 5 cannot be reliably welded together.
There is a problem in that the welded portion of the power cord 6 comes off and moisture intrudes, and if the pressure during welding is increased to further increase the welding force, there is a risk that the insulation performance of the core wire of the power cord 6 will deteriorate.

A heater element 2 formed in a zigzag shape is housed in a fixed sheet 1 made of two synthetic resin sheets, and the synthetic resin sheets between adjacent linear parts of the heater element 2 are welded to form a planar heating element 3. Then, after placing a heat insulating sheet 4 on one side of the planar heating element 3 and storing it in a waterproof bag 5 made of a synthetic resin sheet such as vinyl chloride, the opening of the waterproof bag 5 is welded and sealed. Moisture is prevented from entering the sheet heating element 3.

A synthetic resin bushing 9 having a sheet-like flange 8 is integrally formed on the outer periphery of the power cord 6.
is welded to the periphery of the cord outlet 7 of the waterproof bag 5. When welding, as shown in FIG. 6, a plurality of protrusions 10 are formed to prevent the welded part from elongating due to heat and pressure during welding, and the protrusions 10 are approximately parallel to the thickness direction of the waterproof bag 5. By forming it in the perpendicular direction, it is made easier to bend in the thickness direction, and the thickness of the waterproof bag 5 at the welded portion is prevented from increasing. Furthermore, in order to improve the waterproof performance between the power cord 6 and the bushing 9, the shaded part C in FIG.
are pressure welded.

恐れもなくなるのである。 As described above, in the present invention, a planar heating element to which a power cord for feeding power to a heater element is attached is housed in a waterproof bag made of a synthetic resin sheet, a cord outlet is formed in the waterproof bag, and a cord outlet is formed in the waterproof bag. The power cord extends outside from the outlet, a synthetic resin bushing having a sheet-like flange is integrally formed on the power cord, and the flange and the periphery of the cord outlet of the waterproof bag are welded. Since the parts are welded together, the sheets are reliably welded and waterproof performance is improved, and unlike the conventional example, the power cord is not welded to itself, so there is no risk of deterioration of the insulation performance of the core wire.
