Wound surface therapeutic apparatus

The invention discloses a wound surface therapeutic apparatus according to the principle of the negative pressure and a biological electric field to promote the wound surface repair. The wound surface therapeutic apparatus comprises a supporting cover, a one-way vent valve, electrode plates, a telescopic electrode probe, a power positive and negative electrode contact handle and guide lines. A base of the supporting cover is flat and soft, the electrode plates are installed in the base of the supporting cover and embedded into the base of the supporting cover, the exposed surfaces of the electrode plates are used for making contact with a wound surface, the electrode plates are connected in series through one guide line, and the supporting cover can properly deform according to the contact radian of the wound surface. The electrode plates are connected with the power positive and negative electrode contact handle on the base of the supporting cover through the guide line; the telescopic electrode probe is installed on the side wall of the center of the supporting cover; the electrode probe is externally connected with the power positive and negative electrode contact handle on the outer side wall of the supporting cover through one guide line. The side wall of the supporting cover is provided with the one-way vent valve which is externally connected with a negative pressure generation device. According to the wound surface therapeutic apparatus, negative pressure is formed in the supporting cover through the negative pressure suction, the wound surface therapeutic apparatus is externally connected with a power source to form a biological electric field in the area of the supporting cover, and therefore the healing of the wound surface is promoted rapidly.
