Unless otherwise specified, "plurality" means two or more.

[0016] Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0017] like Figure 1 to Figure 2 As shown, a medical warming blanket comprises a blanket main body and a power cord 1 connected to the blanket main body, the blanket main body comprises a waterproof outer layer 2 and a carbon fiber heating layer 3 installed inside the waterproof outer layer 2, a comfortable buffer layer 4, and a thermal insulation layer 5, wherein the waterproof outer layer 2 is made of medical grade silicone or TPU or nylon material, and its edges are designed to be seamless or hot-pressed sealed to prevent moisture, blood or other liquids from penetrating, ensuring complete waterproofness and easy cleaning; the carbon fiber heating layer 3 is made of highly conductive and high-toughness carbon fibers woven into a mesh structure, which is evenly distributed in the entire blanket main body area; the power cord 1 is made of A medical-grade wear-resistant and fold-resistant power cord 1 is used, and an insulating protective layer is covered on the outside to ensure safe use. An NTC sensor is provided on the carbon fiber heating layer 3. One end of the power cord 1 is connected to an external power supply, and the other end is divided into two paths, which are respectively connected to the carbon fiber heating layer 3 and the NTC sensor. The carbon fiber heating layer 3 is powered by the power cord 1 to produce a far-infrared radiation heating effect. A control module is also provided inside the power cord 1. The control module receives the electrical signal from the NTC sensor and adjusts the current output to the carbon fiber heating layer 3 according to the difference between the set temperature and the actual temperature, thereby achieving precise temperature control.

[0018] In this embodiment, three NTC sensors are provided and evenly distributed on the carbon fiber heating layer 3. Each NTC sensor is connected to the control module of the power cord 1 through a wire, converts the temperature signal into an electrical signal for transmission, and monitors the temperature of each area in real time. When the NTC sensor detects that the temperature in a certain area is too high, the control module will automatically reduce the current output of the area or completely cut off the power to prevent safety accidents such as burns.

[0019] Specifically, the upper end of the carbon fiber heating layer 3 is connected to the thermal insulation layer 5, and the lower end of the carbon fiber heating layer 3 is connected to the comfort buffer layer 4. The thermal insulation layer 5 is located above the carbon fiber heating layer 3, and adopts high-efficiency thermal insulation materials such as polyester fiber to effectively prevent heat from dissipating downward and improve heating efficiency. The comfort buffer layer 4 is a fluffy memory foam structure, which is located below the carbon fiber heating layer 3 and adopts memory foam material to form a soft and elastic support surface, which not only provides comfort but also disperses pressure points and reduces the pressure on the patient's skin caused by long-term surgery. The upper end of the carbon fiber heating layer 3 is tightly connected to the thermal insulation layer 5 by hot melt or adhesive to ensure that heat can be effectively transferred and maintained inside the mat main body. The lower end is connected to the comfort buffer layer 4 by hot melt or adhesive in the same way to ensure the elasticity and stability of the comfort buffer layer 4. The joints are waterproofed to enhance the waterproof performance of the entire mat main body.

[0020] The principle of the implementation mode of the present application is as follows: the main body of the carpet comprises a waterproof outer jacket layer 2 and a carbon fiber heating layer 3, a comfortable buffer layer 4, and a thermal insulation layer 5 installed inside the waterproof outer jacket layer 2; an NTC sensor is arranged on the carbon fiber heating layer 3; a power cord 1 is respectively connected to the carbon fiber heating layer 3 and the NTC sensor; when the external power supply is turned on, the current flows through the power cord 1 inside the main body of the carpet to generate heat; the heat causes the carbon fiber heating layer 3 to generate far-infrared radiation, thereby heating the surface of the carpet; in this process, the NTC sensor can monitor the temperature of the surface of the main body of the carpet in real time and transmit the signal to the control system; the control system obtains the signal from the temperature sensor by heating the carpet; The temperature of the patient's body surface is adjusted by the control of the element. When the control system determines that the patient's body surface temperature is too low, it will send a heating signal to the heating element to generate heat energy. Through the heating effect of the heating element, the temperature of the patient's body surface is increased, thereby achieving the purpose of controlling the patient's body temperature. When the temperature sensor detects that the temperature in a certain area is too high, the control system will automatically reduce the current output of the area or completely cut off the power to prevent safety accidents such as burns. The overall modular design is highly comfortable and easy to disassemble and assemble. All components are made of wear-resistant and corrosion-resistant materials, and their surfaces can be directly wiped with alcohol for disinfection. It is not only convenient and can be reused many times, but also effectively reduces costs.

[0021] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
