The invention discloses a portable treatment device of
electric field coupled with negative pressure for promotion of
wound healing. The device comprises a main part, a sandwich-shaped foam dressing, a first biocompatible transparent membrane,
anode and
cathode patches and a sucker-type drainage tube containing wires; the main part provides negative pressure and direct-
current electric field; the sandwich-shaped foam dressing is a negative pressure drainage material for a wound, and meanwhile is used for providing
electric field for the wound; the first biocompatible transparent membrane is used for covering the dressing and
normal skin around the wound, so that the wound is sealed; the
anode and
cathode patches are used for being connected with a power supply, and are attached to
anode and
cathode carbon
fiber foam dressings respectively; the sucker-type drainage tube containing the wires has dual effects of drainage and electric conduction, one end of the drainage tube is connected with the foam dressing and the anode and cathode patches, and the other end of the drainage tube is connected with the main part. According to the portable treatment device, negative pressure and direct-
current electric field can be applied on the wound synchronously, organic
synergy of sealed negative pressure drainage and direct-
current electric field technologies for promotion of
wound healing is achieved, healing of various acute and chronic wounds is obviously accelerated.
