Description
Technical Field
The invention relates to the field of medical health care products, in particular to a self-heating patch.
Background
Self-heating patches, also known as warming babies, are usually applied to the surface of the body to continuously heat when people feel sore and aversion to cold locally, so as to promote local blood circulation and relieve discomfort symptoms. However, when the self-heating patch is directly attached to the skin surface, the skin surface is easily scalded due to the continuous accumulation of heat, and if the self-heating patch is attached to the outer side of underwear, the heat is difficult to transfer to the skin, and the position of the self-heating patch is difficult to fix along with the movement of the body, so that the heating effect is very limited.
Disclosure of Invention
In view of the above problems, an object of the present invention is to provide a scald preventing self-heating patch, which can prevent a scald on the skin when directly attached to the surface of the skin.
The technical scheme adopted by the invention for solving the technical problems is as follows: the scald-preventing self-heating sticker comprises a sheet-shaped heat storage bag, wherein a heating material is arranged in the heat storage bag, the heat storage bag is made of an air-impermeable material, an air vent area is formed in the upper surface of the heat storage bag, and a removable protective film is covered on the air vent area; an application patch made of a heat-conducting material is arranged on the lower side of the heat storage bag, and the periphery of the application patch is connected with the heat storage bag through a breathable soft material; a thermal deformation bimetallic strip is lined between the heat storage pack and the application sheet; when the temperature of the thermal deformation bimetallic strip is higher than 42 ℃, the thermal deformation bimetallic strip deforms and arches towards the direction orthogonal to the heat storage pack so as to jack the distance between the heat storage pack and the application sheet to be more than 5 mm; and when the thermal deformation bimetallic strip is below 40 ℃, the distance between the heat storage bag and the application sheet is smaller than 2mm due to the deformation and arching amplitude.
Preferably, the upper surface of the thermal storage pack is made of a heat insulating material, so that heat generated by the thermal storage pack is dissipated downward as much as possible.
Preferably, the thermally deformable bimetal is formed of bimetal strips arranged in parallel at equal intervals so as to be uniformly separated and attached everywhere between the heat storage pack and the application plate.
Preferably, two ends of the thermal deformation bimetallic strip are connected with the heat storage bag through heat insulation materials, and the thermal deformation bimetallic strip is arched towards the patch when being heated; after the heat storage pack is separated from the application patch, the thermal deformation bimetallic strip is difficult to cool and restore due to the thermal contact with the heat storage pack.
Preferably, the thermally deformable bimetal is composed of a high manganese alloy layer having a relatively high thermal expansion coefficient and an iron-nickel alloy layer having a relatively low thermal expansion coefficient.
The invention has the beneficial effects that: when the anti-scald self-heating patch is used, the patch is directly pasted on the surface of the skin, when the temperature of the patch is lower, the thermal deformation bimetallic strip only has weak deformation, so that the thermal storage bag and the patch can be close to each other, most of the heat generated by the thermal storage bag is transferred to the patch, and the surface of the skin is heated; when the temperature of the application patch is higher, the thermal deformation bimetallic strip is promoted to generate larger deformation, so that the heat storage pack and the application patch are far away from each other, the heat generated by the heat storage pack is less transferred to the application patch, and the application patch can dissipate heat until the temperature is reduced to the level of preventing the skin from being scalded; therefore, the self-heating patch can be directly attached to the surface of the skin to keep a higher heating temperature, and meanwhile, the skin is not scalded.

Detailed Description
The invention is further illustrated with reference to the following figures and examples:
in the embodiment shown in fig. 1 to 3, the anti-scald self-heating patch comprises a sheet-shaped heat storage bag 1, wherein a heating material 11 is arranged in the heat storage bag 1, and the heating material 11 can continuously oxidize and generate heat after contacting with air. The heat storage bag 1 is made of an air-tight material, the upper surface of the heat storage bag is provided with an air vent area, and the air vent area is covered with a removable protective film 2; an application patch 3 made of a heat-conducting material is arranged on the lower side of the heat storage bag 1, and the periphery of the application patch 3 is connected with the heat storage bag 1 through a breathable soft material; and the thermal deformation bimetallic strip is lined between the heat storage pack 1 and the application patch 3, in the embodiment, the bimetallic strip 41 is mainly arranged in parallel at equal intervals, when the temperature of the bimetallic strip 41 is higher than 42 ℃, the bimetallic strip is deformed towards the direction orthogonal to the heat storage pack 1 and is arched towards the application patch 3, so that the distance between the heat storage pack 1 and the application patch 3 is pushed to be more than 5 mm; and when the bimetal strip 41 is below 40 ℃, the deformation and arching are of such a magnitude that the distance between the thermal storage pack 1 and the application sheet 3 is less than 2 mm.
It is noted that generally, when the skin surface contact temperature is above 42℃, for a slightly longer duration, burning will be noticeable, while below 40℃, substantially no burning will be felt.
In addition, two ends of the bimetal strip 41 can be connected with the heat storage bag 1 through heat insulation materials, and the bimetal strip arches towards the pasting piece 3 when being heated and deformed; to avoid the bimetal strip 41 being continuously heated by the thermal storage pack 1 after the thermal storage pack 1 is separated from the applicator sheet 3. In addition, the upper surface of the thermal storage pack 1 is made of a heat insulating material, so that the heat generated by the thermal storage pack 1 is dissipated downward as much as possible.
When the anti-scald self-heating patch is used, the anti-scald self-heating patch can be directly attached to the surface of the skin, the bimetallic strip 41 is in contact with the application patch 3, when the temperature on the application patch 3 is higher, the bimetallic strip 41 can be deformed by itself to enable the heat storage bag 1 to be far away from the application patch 3, so that the temperature of the application patch 3 is reduced, skin burn is prevented, when the temperature of the area where the bimetallic strip 41 is located is reduced, the original state can be restored, the application patch 3 can be continuously heated, therefore, the temperature of the application patch 3 is balanced to be about 40 ℃, and the skin can feel obvious heat and cannot be burnt.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
