Medical warming blanket

Abstract

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.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to electric heating equipment, in particular to a medical heating blanket. Background technique [0002] Medical warming blanket is a device used for warming up and keeping warm for surgical or non-surgical patients. The medical warming blanket exchanges heat through the contact between the surface of the heating pad and the patient's body, so as to achieve precise control of the patient's body temperature and effectively maintain the normal body temperature of the patient during the perioperative period. [0003] Body temperature is one of the important vital signs of the human body. Maintaining a constant normal body temperature is a necessary condition to ensure the normal progress of human metabolism and life activities. During the operation, due to the low ambient temperature in the operating room (24±2°C), the patient has poor thermal protection, rapid body surface heat dissipa...

Problems solved by technology

This structure determines that it has a large congenital safety hazard. First, the heating of the blanket body is uneven, and the actual temperature of the heating wire needs to be much higher than the set temperature to achieve the effect of heating the entire blanket body. And it is easy to cause local burns on the corresponding parts of the patient where the heating wire is laid, thus causing medical accidents and disputes

Secondly, this structure and the placement position of the temperature sensor and temperature limiter cause the controller to not accurately reflect the actual temperature of the blanket body, causing the blanket body to overheat locally at the position where the heating wire is laid, and the data of the temperature sensor is too low or too high. If the temperature is too high, the controller will give an incorrect heating signal, causing the temperature of the blanket to be out of control, and it is easy to cause a medical accident that causes the patient's overall burn
