Description

Wound auxiliary healing device Technical Field The utility model relates to the technical field of healing devices, in particular to a wound auxiliary healing device. Background A wound healing device is a device or material for promoting wound healing that can accelerate the healing process of a wound by providing appropriate environments and conditions. Common healing devices generally cover a wound with a patch portion to promote wound healing, and are wrapped with medical gauze through a protective face layer. However, when the auxiliary healing device is attached to the wound, body fluid at the wound is extruded and flows out, the patch part is filled with the body fluid after being contacted with the body fluid for a long time, the adsorption effect on the body fluid is poor, the body fluid is easy to flow to the bonding part, the sealing stability of the auxiliary healing device is reduced, and the healing effect on the wound is also reduced. Disclosure of utility model (One) solving the technical problems Aiming at the defects of the prior art, the utility model provides a wound auxiliary healing device, which solves the problems that when the auxiliary healing device is attached to a wound, body fluid at the wound is extruded and flows out, the patch part is filled with the body fluid after being contacted with the body fluid for a long time, the adsorption effect on the body fluid is poor, the body fluid easily flows to an adhesive part, the sealing stability of the auxiliary healing device is reduced, and the healing effect on the wound is also reduced. (II) technical scheme In order to achieve the above purpose, the utility model provides a technical scheme that the wound auxiliary healing device comprises: The surface of the patch part is provided with a negative pressure device, and a drainage tube is inserted into the surface of the negative pressure device; the protective surface layer is arranged at the bottom of the patch part, a first sealing strip is arranged at the bottom of the patch part, and a second sealing strip is arranged on the surface of the protective surface layer; The rubber limiting strips are arranged on two sides of the upper surface of the patch part, and medical gauze is wrapped between the rubber limiting strips. Preferably, the first sealing strip and the second sealing strip are both in a shape of a circle, the second sealing strip is arranged on the periphery of the protective surface layer, and the shape of the circle can enable the first sealing strip and the second sealing strip to seal the contact part of the patch part and the skin, so that external pollution can be prevented. Preferably, the adhesive layer is installed at the bottom of the first sealing strip, the first release paper is adhered to the bottom of the adhesive layer, and the first release paper is taken out, so that the first sealing strip can be adhered to the surface of the skin through the adhesive layer. Preferably, the bottom of paster portion has seted up fluting, the fluting of paster portion and the position looks adaptation of negative pressure device, and negative pressure device can be through the liquid extraction of fluting with the wound, can discharge the liquid or the gas in the wound, promotes wound healing. Preferably, the bottom of the second sealing strip is adhered with a second release paper, the second release paper covers the bottom of the patch part, and the second release paper is taken out to expose the contact part of the bottom of the second sealing strip, so that the second sealing strip is in close contact with the skin. Advantageous effects Compared with the prior art, the utility model provides a wound auxiliary healing device, which comprises the following components The beneficial effects are that: This auxiliary wound healing device can carry out sealing treatment through the edge of first sealing strip to paster portion, can prevent that external air from getting into in the paster portion, thereby can avoid receiving external pollution, and tie up in the surface of paster portion through medical gauze, can extrude paster portion, thereby can drive the surface of second sealing strip to skin and extrude, utilize extruded mode to seal wound, can cover wound promotion wound healing through the protection surface course, simultaneously can take unnecessary body fluid out through negative pressure device, can prevent that body fluid from excessively having reduced auxiliary healing device's sealing stability, thereby can improve the healing effect to the wound.
