Medical drainage hole plaster

Abstract

The invention provides an elliptical medical drainage hole plaster with a concave-convex surface layer design. The plaster is composed of a water absorbing core, a semitransparent backing layer and an annular adhesive layer, wherein the water absorbing core is made of a strong water-absorbing material; the center of the medical drainage hole plaster is provided with a circular bulge; the outer periphery of the medical drainage hole plaster is provided with an annular leakage-preventing groove; the water absorbing core is composed of two layers; one layer, facing to skin, of the water absorbing core is arranged longitudinally, and contains drugs for promoting skin repairing and inhibiting bacterial growth; one layer, close to the backing layer, of the water absorbing core is designed transversely, and contains an ingredient which changes color under the condition of being in contact with water. The medical drainage hole plaster disclosed by the invention has the advantages that the contradiction among quick absorption, prevention of transverse diffusion and increment of water storage volume is solved, the characteristic of being suitable for radian of a human torso is obtained, the blocking effect is good, the air permeability is also good at the same time, the medical drainage hole plaster is prevented from being adhered to the skin, the advantages of promoting quick healing of a drainage hole and giving a warning on drainage hole exudate in a color developing manner are obtained at the same time, and a patient is prompted to change the plaster timely.

Description

technical field [0001] The invention relates to a medical dressing which has good absorbency for the exudate at the drainage hole, can maintain a sterile and breathable environment at the drainage hole for a long time, and promotes the rapid healing of the drainage hole. Background technique [0002] Drainage tubes are used in clinical surgery to guide pus, blood, and fluid accumulated between human tissues or in body cavities to the outside of the body, but the drainage holes after the drainage tubes are taken out are not easy to heal, and gauze, sponges, etc. are generally used clinically, and most of them pass through the drainage holes The exudate will dry the drainage hole and then heal. Since the drainage hole will leak out, new auxiliary materials need to be replaced frequently, which not only increases the frequency of operation, but also easily causes postoperative infection.

Problems solved by technology

[0002] Drainage tubes are used in clinical surgery to guide pus, blood, and fluid accumulated between human tissues or in body cavities to the outside of the body, but the drainage holes after the drainage tubes are taken out are not easy to heal, and gauze, sponges, etc. are generally used clinically, and most of them pass through the drainage holes The exudate will dry out the drainage hole and then heal. Since the drainage hole will leak out, new auxiliary materials need to be replaced frequently, which not only increases the frequency of operation, but also easily causes postoperative infection.

[0003] In recent years, the following problems have been found in the dry healing of the drainage hole: 1) local dehydration of the drainage hole, forming scabs, which hinders the crawling of epithelial cells; 2) loss of bioactive substances in the drainage hole, and slow healing speed; 3) frequent dressing changes , so that the local temperature of the drainage hole drops, resulting in slow cell division and proliferation; 4) There is no barrier between the drainage hole and the outside world, and the chance of infection increases; 5) The healing time of the drainage hole is long; 6) The dressing and the new granulation tissue of the drainage hole stick connected, resulting in re-injury every time the dressing is changed, causing pain to the patient

These dressings have the following problems in the drainage hole healing: 1) the dressing with good air permeability cannot continuously absorb the exudate; 2) although the hydrocolloid dressing can absorb the exudate, it is easy to leave a gelatinous substance in the drainage hole, which needs to be replaced. 3) Some dressings have no adhesion and need to be applied with auxiliary adhesive tape; 4) Some dressings are too adhesive and stick to the skin when replaced, which is not only painful, but also causes loss of regenerated skin; 5) Cannot heal the drainage hole Provides a sterile and growth-promoting ideal environment

[0006] Therefore, there is no specific dressing for the drainage port, which can meet the multiple factors of rapid healing of the drainage port at the same time, including: maintaining a closed but breathable environment, being sticky but not sticking to the skin of the drainage port, ensuring sterility and promoting drainage Ideal environment for oral skin growth
