A composite wound dressing apparatus promotes healing of a wound via the use of a micropump system. The micropump system includes a micropump that applies a subatmospheric pressure to the wound to effectively draw wound fluid or exudate away from the wound bed, or deliver fluids to the wound bed, without the need for a cumbersome external pressure (e.g. vacuum) source. Hence, the wound dressing and micropump system is portable which allows the patient mobility that is unavailable when an external vacuum source is used.
一种复合伤口敷料装置通过使用微泵系统促进伤口愈合。微泵系统包括一个微泵,可对伤口施加亚大气压,从而有效地将伤口液体或渗出物从伤口床吸走,或将液体输送到伤口床,而不需要笨重的外部压力(如真空)源。因此,伤口敷料和微型泵系统是便携式的,病人可以移动,而使用外部真空源时则无法移动。
