When the heat collecting bag 11 is in the unfolding state, the first surfaces of all the sub heat bags are coplanar, and the second surfaces of all the sub heat bags are coplanar; when the heat collecting bag 11 is in a folded state, the first face of the sub-heat bag is attached to the first face of the adjacent sub-heat bag, the second face of the sub-heat bag is attached to the second face of the adjacent sub-heat bag, the sub-heat bags are parallel to each other, the edges of the sub-heat bags are cut on the same virtual face, and the sub-sheet bodies are attached to the adjacent sub-sheet bodies with different groups.

Preferably, a magnetic attraction piece is arranged on one side of the sheet-shaped body 12 away from the heat collecting bag 11, specifically, at least two magnetic attraction pieces which are uniformly distributed are arranged on one surface of each sub-sheet-shaped body away from the heat collecting bag of the same group, and the distance between the two magnetic attraction pieces which are farthest apart on the same sub-sheet-shaped body is greater than or equal to half of the length of the sub-sheet-shaped body. Under the folding state, the magnetic attraction pieces on the two sub-sheet bodies which are attached are oppositely arranged and attracted with each other and are used for positioning the sub-sheet bodies and the sub-heat bags fixedly connected with the sub-sheet bodies.

Further preferably, one surface of the two sub-sheet bodies which are attracted with each other is provided with a convex edge, the other surface of the sub-sheet bodies is provided with grooves corresponding to the convex edges one by one, the magnetic attraction pieces are arranged on the convex edges and in the grooves, when the heat collection assembly 1 is in a folding state, the convex edges slide into the grooves, the magnetic attraction pieces are attracted with each other, positioning is realized, and the cross section shape of the convex edges is preferably semi-elliptic or triangular.

It should be noted that, in order to avoid that the phase change material affects the folding of the heat collecting pouch 11 in the low temperature phase, the phase change material should be small particles and wrap the material having a melting point greater than the use temperature around the particles, or the phase change material should be foldable in the low temperature state.

Referring to fig. 3, the light emitting assembly 2 includes a substrate 21 and light emitting chips 22, and the light emitting chips 22 are arrayed or equidistantly distributed on a surface of the substrate 21 away from the heat collecting bag 11.

In this embodiment, the substrate 21 includes a multi-stage sub-substrate, which is a hard substrate such as the BT resin substrate 21 and ABF thin composite substrate 21.

Preferably, the back of the sub-substrate is provided with a heat conducting fin in a bonding manner, and the heat conducting fin stretches into the sub-heat bag so as to increase the heat conducting effect.

It should be noted that the technical effect of the present application is to guide the heat inevitably generated in the operation of the light-emitting component 2 to the heat-collecting bag 11 to facilitate the subsequent hot compress, besides, the light is not only absorbed by the patient, but also the rest light is converted into heat, and the conversion amount can be flexibly adjusted according to the actual situation. Specifically, the sheet-shaped body 12 extends outwards, so that more light can be converted into heat while the distance from the light generated by the light-emitting component 2 to the body surface of the patient is increased; the white paint or the high-reflection film is coated on the side of the sheet-shaped body 12 close to the heating component, so that the absorption of the sheet-shaped body 12 to light rays can be reduced, and the heat generation can be reduced. In case the power of the light emitting assembly 2 is too high to adjust the reduction, a suitable conversion of light energy into heat energy is also a conceivable balancing scheme.

The implementation principle of the embodiment 1 is as follows:

when the heat collecting bag 11 is in a folded state, adjacent non-same groups of sub-sheet bodies are attached, the opening of each accommodating space 13 forms a complete light emitting surface, and the LED light-emitting device for physiotherapy is configured to be in a phototherapy state. The light emitting component 2 works, and the light emitting chip 22 with the corresponding wavelength is started according to the treatment requirement, on one hand, the work of the light emitting component 2 can enable the temperature of the substrate 21 and the temperature of the light emitting chip 22 to rise, and the generated heat is conducted into the heat collecting bag 11; on the other hand, most of the light generated by the light emitting component 2 is reflected by the sheet-shaped body 12 to be irradiated on the affected part, and the small part is absorbed and converted into heat energy, and then is conducted to the heat collecting bag 11. The cooling liquid in the heat collecting bag 11 absorbs heat to raise temperature, or the phase change material absorbs heat to raise temperature to the phase change temperature, and then phase change occurs, so that the heat energy is absorbed and converted into intermolecular potential energy for storage under the condition of unchanged temperature.

Specific light effects are compatible with the condition, for example: the neonatal jaundice is treated with blue light with a wavelength of 470nm, fat-soluble bilirubin is converted into water-soluble bilirubin, and jaundice deposited on the skin is discharged from the body through stool.

After the phototherapy is finished, the sheet-shaped body 12 is cooled slightly, and after the temperature of the sheet-shaped body is close to that of the heat collecting bag 11, the heat collecting bag 11 is unfolded and laid on the region to be fomented by the patient. The cooling liquid outputs heat to the affected part to realize hot compress; or the phase change material is subjected to phase change by a high Wen Xiangxiang low-temperature phase, intermolecular potential energy is converted into heat output, and the constant-temperature hot compress is carried out by the LED light-emitting device for physiotherapy.

It should be noted that, in order to prevent low-temperature scald, the LED light emitting device for physiotherapy, especially the sheet-shaped body 12, should be prevented from directly contacting the skin, or a layer of padding such as wool felt should be added outside the device.

Example 2

Referring to fig. 4 and 5, the difference between this embodiment and embodiment 1 is that the substrate 21 in this embodiment is a flexible circuit board, the sheet 12 is also a flexible material, and the substrate 21 is attached to one side of two opposite sheet 12, which is close to the heat collecting bag 11.

Referring to fig. 6, it is preferable that two substrates 21 are disposed opposite to each other in the accommodating space 13, and the two substrates 21 are attached to the sides of the two sheet-like bodies 12 near the heat collecting cells 11, respectively.

Alternatively, the substrate 21 is connected in multiple segments.

The implementation principle of the embodiment 2 is as follows: the flexible circuit board and the flexible sheet 12 can be bent along with the heat collecting bag 11, and the heat collecting bag 11 is folded without conforming to the division of the sub-substrate and the sub-sheet, so that various shapes and sizes of the light emitting surface can be folded more flexibly.

It should be noted that, in the present embodiment, if the shape of the light emitting surface is flexibly adjustable while the magnetic attraction pieces are provided, the magnetic attraction pieces on the same sheet 12 should be distributed equidistantly, and the adjacent magnetic attraction pieces have different poles.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
