A recently filed patent (Publication Number: US20230301824A1) describes a medical heating device designed to heat a person. The device consists of an electronic control unit that can be recycled and a flexible heating blanket that partially shields the person from the surrounding environment. The heating blanket is designed to be separable from the control unit without being destroyed and can be regularly replaced as a disposable item. The heating layer of the blanket is made up of a carrier layer of polymeric material and a resistance layer of electrically conductive material, which converts electrical energy into heat. The device also includes a plurality of temperature sensors that control the heating layer.

The heating blanket in the device may have multiple heating elements, allowing for more efficient and targeted heating. Additionally, the temperature sensors may only measure a portion of the heating element, providing more precise control over the heating process. The heating layer itself may consist of multiple heating elements with a common polymeric carrier layer, and some of the temperature sensors may be arranged in a band-like and flexible sheet structure along the longitudinal axis of the blanket. This arrangement allows the sensors to detect the temperature in the heating element. The sensor connecting conductors may have deflections along the course of the blanket, and the sensor field may be an integral part of the resistance layer, using the carrier layer as a sensor carrier.

In summary, the patent describes a medical heating device that includes a recyclable electronic control unit and a disposable, separable heating blanket. The blanket is designed to shield the person from the environment and is made up of a heating layer with multiple heating elements. The device also includes temperature sensors for precise control over the heating process. The patent further details the arrangement of the heating elements, temperature sensors, and sensor connecting conductors within the blanket.
