Description

Technical Field

[0001] The utility model relates to the technical field of wound dressing auxiliary pads, and specifically relates to a disposable sterile auxiliary pad for wound dressing. Background Technique

[0002] When a wound and stoma specialist nurse performs a dressing change operation on a patient, it is often necessary to use hemostatic forceps, tweezers, and blades to pick up necrotic tissue, blood clots, surgical sutures, dead skin cutin, etc. from the patient's wound surface. In the past, nurses usually had the following three methods:

[0003] Lay a piece of gauze beside the wound surface. After the tissue forceps are soiled by picking up tissue from the wound surface, wipe them clean on the gauze piece and then continue the operation;

[0004] However, due to the patient's movement or the position of the wound itself, the gauze piece cannot be fixed and is easy to fall off. The nurse needs to hold the gauze with one hand, wipe the soiled tissue forceps clean on the gauze piece after picking up the tissue, and use hemostatic forceps or tweezers with the other hand to operate. Only one hand can be used to handle the wound. Wiping the instrument with one hand while holding the gauze violates the aseptic principle; the nurse wipes or discards the soiled tissue, exudate, removed sutures, and skin staples on the disposable dressing waste tray on the treatment cart beside, resulting in frequent back-and-forth trips during the operation and lack of energy conservation.

[0005] Therefore, a disposable sterile auxiliary pad for wound dressing is proposed. Content of the Utility Model

[0006] The purpose of the utility model is to provide a disposable sterile auxiliary pad for wound dressing to solve the problems raised in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A disposable sterile auxiliary pad for wound dressing, including a pad body,

[0008] The pad body is in the shape of a rectangular pocket;

[0009] The pad body is composed of a lower covering pad and an upper covering pad;

[0010] The area of the upper covering pad is half of that of the lower covering pad, and the right ends of the lower covering pad and the upper covering pad are aligned.

[0011] Preferably, both the lower covering pad and the upper covering pad are of a three-layer structure from the outside to the inside, namely a surface layer, an adsorption layer, and a bottom film layer.

[0012] Preferably, the bottom surface of the lower covering pad is provided with an adhesive. The three contact positions of the lower covering pad and the upper covering pad are hermetically connected. There is a low-viscosity adhesive at the bottom of the lower covering pad, which can be adhered to the clothes around the patient's wound or the intact skin, and can be gently torn off without damaging the normal skin tissue.

[0013] Preferably, the opening of the upper covering pad is designed in an arc shape, and the radian of the opening of the upper covering pad is between 30° and 140°, which is convenient for placing the debrided tissue of the patient.

[0014] Preferably, the bottom film layer is composed of a waterproof film, the thickness of the bottom film layer is 0.1 mm, and the waterproof film is a breathable and waterproof film.

[0015] Preferably, the adsorption layer is composed of sterile medical cotton, the thickness of the adsorption layer is 0.4 mm, and it can absorb the debrided blood, tissue fluid, etc. of the patient.

[0016] Preferably, the surface layer is composed of sterile medical gauze, and the thickness of the surface layer is 0.2 mm.

[0017] Preferably, the bottom film layer, the adsorption layer and the surface layer are bonded with hot melt adhesive.
