Slow releasing solution and absorption type dressing

Abstract

An absorbable dressing able to slowly release solution is composed of a skin-contacting layer with multiple conic holes, an absorbing layer containing the water-soluble antibacterial agent, ferment and growth factor powder, a guide layer for guiding the exudate from wound to absorbing layer, where it becomes hydrogel, and an air permeable layer.

Description

technical field [0001] The present invention relates to an absorbent dressing for slow release of solutions. Background technique [0002] At present, when medical institutions treat external wounds of the human body, such as cuts, surgical incisions, ulcers or burns, etc., it is usually necessary to cover or bandage the wounds with sterilized dressings to prevent infection by external bacteria. Looking at the dressings commonly used in medical institutions at present, most of them are still gauze or cotton pads made of sterilized cotton sandwiched between two layers of gauze. The dressing is covered or bandaged on the wound. Although it has the effect of absorbing wound exudate, However, it will seep back to corrode the skin around the wound, easily cause infection or the absorbed exudate is easy to volatilize and make the gauze hard and hurt the wound. When changing the dressing, the gauze is stuck to the wound, and taking it off not only causes pain to the patient, but al...

Looking at the dressings commonly used in medical institutions at present, most of them are still gauze or cotton pads made of sterilized cotton sandwiched between two layers of gauze. The dressing is covered or bandaged on the wound. Although it has the effect of absorbing wound exudate, However, it will seep back to corrode the skin around the wound, easily cause infection or the absorbed exudate is easy to volatilize and make the gauze hard and hurt the wound. When changing the dressing, the gauze is stuck to the wound, and taking it off not only causes pain to the patient, but also hurts the wound It is necessary to try to solve the lack of new inner bud tissue, etc.

Although there is the No. 590763 patent announced in Taiwan, China, it directly contacts the wound surface with an active gel layer, and uses the top sheet that has covered the outer layer of the absorbent layer to prevent the wound fluid from flowing back to the wound surface , and its absorbent layer releases a high level of medicament to the wound surface when it is wet. The preparation of the hydrogel layer, regardless of whether the wound surface is dry or wet, is in direct contact with the preparation. the timing is not ideal
