Description

Composite dressing for preventing phlebitis Technical Field The invention relates to the technical field of dressing, and particularly provides a composite dressing for preventing phlebitis. Background Therapeutic venous injury is a chemical reaction caused by local skin swelling and pain, even tissue necrosis, and the like, due to intravenous infusion of high-concentration and strong-irritation medicaments or due to long-term placement in veins and large-irritation plastic catheters. The toxicity of the chemotherapy medicine can damage blood vessels, and the aseptic technique operation in the transfusion process is not strict, so that phlebitis can be induced. The existing treatment method for the chemotherapeutic vein injury mainly comprises cold compress, hot compress, magnesium sulfate wet compress, local sealing therapy, external application of traditional Chinese medicine and the like. However, the external application of traditional Chinese medicines is mostly temporarily formulated into paste or powder, which has the problems of unstable dosage form, difficult fixation, easy pollution to clothes and difficult synchronization with cold compress, and has poor use experience. Disclosure of Invention The invention provides a composite dressing for preventing phlebitis, which is used for solving the problems that the traditional Chinese medicine external application dosage form is unstable, is not easy to fix and pollute clothes, and cannot be synchronous with cold compress, so as to improve the use experience of the dressing. The technical scheme of the invention is as follows: The utility model provides a prevent complex dressing of phlebitis, includes inlayer, cold blanket layer and skin, cold blanket layer and inlayer and skin contact, the cold blanket layer sets up between inlayer and skin, the inlayer includes substrate and traditional chinese medicine composition of intermixing, the substrate includes the hydrogel, traditional chinese medicine composition mixes the inlayer that forms layered structure with the hydrogel, the cold blanket layer includes the refrigeration portion, the skin includes fixed part. In order to solve the problem that the refrigerating part causes discomfort of skin near the vein and the use experience of a user is poor, the cold compress layer comprises a plurality of refrigerating parts, and the refrigerating parts are distributed in an array mode. In the scheme, the refrigerating part can be activated along the trend of the vein, so that cold compress is accurately performed on the vein, discomfort of skin near the vein is reduced, and use experience is improved. The refrigerating part comprises two mutually isolated chambers, the two chambers are respectively filled with a phase change material and an activating material, the activating material is used for activating the phase change material, and the phase change material absorbs heat after being contacted with the activating material. The refrigerating part also comprises an isolation structure for separating two chambers, or one chamber is a vesicle, the vesicle is positioned in the other chamber, the vesicle is filled with an activating material, and the other chamber is filled with a phase change material. The second aspect of the invention is used for solving the problem of low utilization rate of the traditional Chinese medicine components in the composite dressing, and for this purpose, the refrigerating part further comprises a slow release structure, the slow release structure is used for separating the phase change material and the activating material, and the slow release structure is dissolved in the activating material. The slow release structure can delay the activation of the refrigerating part, so that the traditional Chinese medicine components are fully absorbed before the refrigerating part is activated, and the utilization rate of the traditional Chinese medicine components is improved. The shape of the isolation structure is sheet-shaped, the isolation structure is configured with a curved surface, and the concave side of the curved surface faces the inner layer. Preferably, the outer layer is provided with a receiving groove for receiving a refrigerating part, and the refrigerating part is disposed in the receiving groove. In this scheme, set up the holding tank and hold the refrigeration portion, be equivalent to the clearance between the refrigeration portion and fill by the lateral wall of holding tank, ensure that the cold compress layer bottom that the refrigeration portion formed is level and smooth to evenly contact with the inlayer, thereby ensure that the heat conduction effect is even stable. According to the invention, the problem of infection at a puncture site caused by sweat or external liquid infiltrating into an inner layer is solved, and therefore, the outer layer comprises edges which are adhered to the skin, a drainage groove is arranged at the position where the outer layer is
