The invention relates to a medical
warming blanket. The medical
warming blanket comprises a power supply section, a controller and a
heating pad. The
heating pad consists of 7
layers of structures which include a medical multilayer composite non-
woven fabric coating layer, a composite cotton heat insulating layer, an insulating non-
woven fabric layer, a net carbon
fiber heating body layer, an insulating non-
woven fabric layer, a composite cotton heat insulating layer and a medical multilayer composite non-woven fabric
coating layer in sequence from top to bottom. Carbon
fiber heating bodies are made of
carbon fibers and 100% cotton fibers in a
spinning mode, multiple strands of carbon
fiber heating bodies are regularly arranged into a planar net structure, and the two ends of each carbon fiber heating body are connected to a heating circuit of the
heating pad through
copper sheets. The net carbon fiber heating bodies are combined in a hot melting mode by the two insulating non-woven fabric
layers to form a whole heating layer. Three paths of independent over-temperature alarm protection devices are arranged in the controller and the heating pad. The surface of a temperature sensor and the surfaces of two paths of heat protectors are both tightly attached to the whole heating layer through a piece of heat-conducting
aluminum foil or
copper sheet, wherein the whole heating layer is formed by the net carbon fiber heating bodies and the two insulating
nonwoven fabric layers in a hot-melting combination mode. The modular
integrated circuit design is adopted for the controller. With the refreshing frequency of 0.5 second and the
temperature control precision of 0.1 DEG C, the intelligent real-
time control and display of the temperature of the heating pad are realized.
