[0016] Please see the attached Figure 1 -Attached Figure 3 The embodiment of the present invention proposes a multi-point constant temperature hot compress instrument, which includes: a controller 1; and a plurality of hot compress bags 2 that can be arranged independently, each hot compress bag 2 is provided with an independently working temperature sensor 3 and a heating plate 4; wherein, the temperature sensor 3 and the heating plate 4 of each hot compress bag 2 are electrically connected to the controller 1, and the controller 1 can control each heating plate 4 to generate heat separately.

[0017] Based on the above technical solution, the utility model includes a controller 1 and a plurality of hot compress packs 2 that can be arranged independently. Each hot compress pack 2 is provided with an independently working temperature sensor 3 and a heating plate 4. The temperature sensor 3 and the heating plate 4 of each hot compress pack 2 are electrically connected to the controller 1. The controller 1 can independently control the heating of the heating plate 4 and accurately control the heating temperature of the heating plate 4 through the corresponding temperature sensor 3. Therefore, the hot compress pack 2 of the utility model can be applied to any part of the user's body, and the controller 1 can simultaneously control multiple hot compress packs 2 to accurately heat up and automatically maintain a constant temperature, so that it can simultaneously perform hot compresses of different temperatures on different parts of the user's body according to their needs.

[0018] The number of the hot compress packs 2 of the present invention is 2-4, which can be 2 or 4. The outer dimensions of these hot compress packs 2 vary, for example, the length x width is: 40cm x 60cm, 50cm x 90cm, 100cm x 200cm, etc. They are light, thin and compact, can meet the needs of hot compress users, and do not affect the normal work and life of users at all.

[0019] The hot compress pack 2 of the present invention includes an inner layer 5, a temperature sensor 3, a heating plate 4, and an outer thermal insulation layer 6; the inner layer 5, the temperature sensor 3, the heating plate 4 and the outer thermal insulation layer 6 are stacked in sequence, the inner layer 5 is configured to contact human skin, the temperature sensor 3 is arranged between the inner layer 5 and the heating plate 4, and the heating plate 4 is arranged between the temperature sensor 3 and the outer thermal insulation layer 6.

[0020] The heating control circuit 10 inside the controller 1 can control the heating plate 4 to generate heat. The heating plate 4 will heat up the heat pack 2. The heat pack 2 is attached to the user's skin - the inner layer 5 is close to the user's skin, and the heat is transferred to the part of the user that needs hot compress.

[0021] In addition, the present application sets the temperature sensor 3 near the inner layer 5, and the inner layer 5 is close to the user's skin. In this way, the temperature sensor 3 can accurately collect the skin temperature of the user's part to be heated, which can facilitate setting the specific heating temperature to achieve the best heating effect.

[0022] The heating sheet 4 can be made of materials such as graphene and carbon fiber. The heating sheet 4 is designed to be lighter and smaller. When used, it can be used with a headgear, hat, gloves, elbow pads, knee pads, socks, a vest, pants, or a special elastic bandage, etc., and clamped close to the skin to achieve efficient hot compress.

[0023] In order to ensure that heat is not lost and the temperature of the hot compress pack 2 is constant, the outer insulation layer 6 is made of beautiful, durable and lightweight insulation cotton cloth.

Here, you can refer to the materials that meet the above requirements in the existing technology, and select and process the inner layer 5 and the outer insulation layer 6 of the hot compress pack 2 accordingly.

[0027] Generally, the temperature required for hot compress is between 40℃ and 48℃. In fact, the temperature change threshold can be set to 0.1℃. For a certain hot compress pack, if it increases by 0.1℃ in one unit time, it must decrease by 0.1℃ in the next unit time. In this way, the temperature of the entire hot compress process will be constant at the set temperature point within 40℃-48℃ to ensure that the user is given the best hot compress during the entire hot compress process.

[0028] The temperature sensor 3 of the utility model adopts a thermistor temperature probe, which can achieve a resolution of 0.1°C, monitor and refresh the sensed temperature in real time, and adjust the heating power of the heating plate 4 according to the set temperature.

[0032] As mentioned above, the number of hot compress packs 2 of the present invention can be 2-4, for example, 2 or 4, but sometimes, the user does not use all the hot compress packs, and the remaining hot compress packs can be removed and left idle to avoid affecting the user's hot compress; in the present invention, the connection method between the power supply male end and the power supply female end can be a plug-in connection method.
