Heat transfer device: seal and thermal energy contact units
A device has four fundamental components: an enclosure, a soft seal, a vacuum system and a thermal energy system having a thermal energy contacting element. The device provides thermal energy therapy and negative pressure therapy device simultaneously and/or in conjunction to a patient. The device has a thermal energy system that is more efficient in thermal energy transfer and the soft seal decreases tissue interface pressure to obtain the desired soft seal effect.
