Description

Be used for prosthetic subsides of burn surface of a wound to apply device Technical Field The invention belongs to the technical field of burn plaster laying and preparation, and particularly relates to a plaster device for repairing burn wounds. Background After the skin of a burn patient is damaged, the wound surface needs to be covered by a dressing to maintain the moist environment of the wound surface so as to isolate external infection and promote healing. The ideal burn dressing can continuously and uniformly release the medicine, avoid secondary damage caused by frequent replacement, and has good air permeability, fit and medicine absorption efficiency so as to accelerate the wound repair process. At present, the traditional gauze or fixed application is often adopted for the application mode of burn patients, and the traditional gauze or fixed application needs to be removed integrally when changing the medicine, so that new tissues are easily involved, and pain and secondary wounds are caused. In addition, the existing dressing often lacks a sustained drug release mechanism, which causes uneven drug absorption and residual drug stains to affect the new drug effect, and most of the dressing cannot be flexibly cut and attached according to the shape of a wound surface, so that the convenience and the treatment effect of clinical use are reduced. Therefore, there is an urgent need for a burn repair dressing device that can change the dressing without uncovering the dressing, recover the last residual drug that has not been absorbed during dressing change, and adapt to different wound morphologies. Disclosure of Invention Aiming at the situation, in order to solve the defects that the applied medicine needs to be frequently replaced, the cured medicine remains, the application suitability is poor and the like in the treatment of burn patients, the invention provides an application device for repairing burn wound surfaces, and the problems that the traditional application is easy to cause secondary wounds when being replaced, the replacement frequency of the application is fast, the wound recovery is not facilitated, the body surface residual medicine is cured, and the application of wound surfaces of different shapes is difficult to attach are effectively solved. The technical scheme adopted by the invention is that the dressing device for repairing the burn wound comprises a body surface dressing layer, a reagent limiting release layer and a medicine storage layer, wherein the body surface dressing layer is clung to burn skin, net-shaped small holes are formed in the body surface dressing layer and are beneficial to medicine permeation and absorption by the skin, the reagent limiting release layer is arranged above the body surface dressing layer, the body surface dressing layer is fixedly connected with the reagent limiting release layer, the medicine storage layer is connected with the reagent limiting release layer, and the medicine storage layer is clamped and installed on the reagent limiting release layer to realize the design effect that medicine is released from the medicine storage layer and absorbed by the skin. Further, the medicine storage layer includes upper cover membrane, upper bleeder vent, medicine fixed cover, presses the arch, the upper cover membrane covers on the upper wall of the spacing release layer of reagent, the upper cover bleeder vent sets up on the upper cover membrane, the fixed cover of medicine is fixed to be set up on the central point of upper cover membrane, press the fixed diapire that sets up on the upper cover membrane of protruding, press the protruding medicine that can be between the spacing release layer of reagent and the body surface subsides coating downwards to press, promote the absorption efficiency of medicine and skin, the fixed cover of medicine has elasticity. Further, the medicine storage layer further comprises a liquid storage tank, a sliding limiting layer and a wound covering soft plate, wherein the sliding limiting layer is connected with the liquid storage tank through a bracket in a clamping way, the wound covering soft plate is fixedly arranged on the bottom wall of the sliding limiting layer, and the liquid storage tank, the sliding limiting layer and the wound covering soft plate are combined into a cylindrical structure; The outer wall of slip spacing layer comprises four fan-shaped stands that the shape is the same, the both ends of fan-shaped stand are equipped with draw-in groove and fixture block respectively, all be equipped with the latch on the fixture block, be equipped with the block groove that is used for the latch in the draw-in groove, be favorable to four groups fan-shaped stand keep the stable in structure of slip spacing layer when constituteing a set of cylindricality structure, the centre of a circle department of slip spacing layer is equipped with the stand spout, be equipped with the gliding hydraulic column of bl
