通常,如果伤口愈合不好,需要进行手术去除腐烂组织以帮助健康新生组织生长。然而,一旦用常规创可贴覆盖伤口后,医生很难了解伤口愈合情况。如果频繁撕开创可贴观察伤口则会给患者带来痛苦,还会增加感染的风险。虽然已有探针式的设备可以测量损伤组织的氧气水平,但该方法只能在开放伤口上实施。新的创可贴涂上含有荧光分子的溶液,溶剂挥发后会形成密封薄膜。这种创可贴含有的荧光分子能感应 Often, if the wound does not heal well, surgery is required to remove the decayed tissue to help healthy new tissue to grow. However, once the wound is covered with a conventional band-aid, it is hard for the doctor to understand the wound healing. If you frequently tear open the bandage to observe the wound will give patients pain, but also increase the risk of infection. Although probe-type devices are available to measure oxygen levels in injured tissue, this method can only be performed on open wounds. The new Band-Aid is coated with a solution containing a fluorescent molecule that evaporates to form a sealed film. This band-aid contains fluorescent molecules that sense
