Problems solved by technology

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

Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings. The embodiments are only preferred embodiments of the present invention, and should not limit the scope of the present invention. That is, all equivalent changes and modifications made according to the scope of the patent application of the present invention should still fall within the scope covered by the patent of the present invention.

[0011] Please refer to Fig. 1, shown in Fig. 2, dressing 1 of the present invention, by: wound contact layer 2, diversion layer 4, absorbing layer 5, and air-permeable layer 6 overlap each other successively or carry out dot-matrix glue to be bonded in peripheral heat fusion 7 in one, with various sizes of different specifications of sterile packaging (not shown in the figure), in order to cooperate with the use of wounds of different sizes. Wherein, the wound contact layer 2 is a suitable film, which is covered with conical holes 3....

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...
