    • A tissue treatment apparatus includes a bandage that is transparent to, or transmissive of, energy in a predetermined range of the infrared (IR) portion of the electromagnetic spectrum. The bandage includes a layer that acts as a bandpass filter, permitting IR radiation in the range of wavelengths between 3 and 30 &mgr;m to pass through the bandage to tissue against which the bandage is disposed. A heater is used to generate heat, including IR radiation, and an attachment device retains the heater over or on the bandpass bandage layer. The bandage and heater together have a low profile so as to be convenient for a patient, and are flexible so as to conform to the shape of a wound and to contours of the skin near the wound. The bandage is provided with an adhesive pattern for maintaining moisture at the wound site. The heater may maintain a normothermic condition at subdermal regions of the wound treatment area. A controller may be provided for cycling the temperature of the heater in order to maintain the normothermic condition.
    • 组织处理装置包括对电磁光谱的红外(IR)部分的预定范围内的能量透明或透射的绷带。 绷带包括用作带通滤光器的层,允许在3至30μm之间的波长范围内的IR辐射通过绷带传递到组织,绷带布置在组织上。 加热器用于产生热量,包括红外线辐射,并且连接装置将加热器保持在带通绷带层上或上。 绷带和加热器一起具有低轮廓,以便于患者,并且是柔性的,以便符合伤口的形状和伤口附近的皮肤轮廓。 绷带设置有用于在伤口部位保持水分的粘合剂图案。 加热器可以在伤口治疗区域的皮下区域保持正常的体温状态。 可以提供控制器来循环加热器的温度以便保持正常的体温条件。
