Heating device

A system comprising:

• a heating device for wound healing, the heating device having:
• a wearable layer conformable to a part of a user's body;
• a heat source attached to the wearable layer for applying heat to a region of a user's body;
• one or more blood flow sensors attached to the wearable layer configured to detect a parameter indicative of blood flow in or adjacent to the region of the user's body and generate a signal indicative thereof;
• and
• one or both of:
• (i) a processor in electrical communication with the one or more blood flow sensors for determining the blood flow in or adjacent to the region of the user's body based upon the signal;
• or
• (ii) a transmitter for transmitting the signal to a remote device,
• wherein the heating device is a bra cup, or an insert for inserting into a bra cup, and the heating device and the one or more blood flow sensors are arranged to generally surround, in use, a user's areola,
• wherein either:
• the processor (i);
• or
• a separate processor in communication with the one or more blood flow sensors, is configured to compare the blood flow to a threshold value and generate a notification if the blood flow is less than the threshold value.

A method of heating a region of a user's body comprising the steps of:

• providing a heating device, the heating device comprising:
• a wearable layer conformable to a part of a user's body;
• a heat source attached to the wearable layer for applying heat to a region of a user's body;
• one or more blood flow sensors attached to the wearable layer configured to detect a parameter indicative of blood flow in or adjacent to the region of the user's body and generate a signal indicative thereof;
• and
• one or both of:
• (i) a processor in electrical communication with the one or more blood flow sensors for determining the blood flow in or adjacent to the region of the user's body based upon the signal;
• or
• (ii) a transmitter for transmitting the signal to a remote device, wherein the heating device is a bra cup, or an insert for inserting into a bra cup, and the heating device and the one or more blood flow sensors are arranged to generally surround, in use, a user's areola;
• placing the wearable layer on a user's body so that the heating device is in thermal contact with a user's body;
• activating the heat source to apply heat to a region of the user's body;
• and
• using the blood flow sensors to detect blood flow in the region of the user's body.
