Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a medical sterile dressing film. Background Technology

[0002] Medical sterile dressings are typically soft, elastic films made with a water-soluble polymer matrix, an inner polyurethane hydrogel, and an outer medical nonwoven fabric. They are coated with medical pressure-sensitive adhesive and may include absorbent, insulating, and protective layers to ensure sterility and functionality.

[0003] Existing sterile medical dressings are designed for single-use application, requiring complete removal for replacement. The adhesive method of attaching the dressing to the skin causes discomfort during removal. Furthermore, frequent changes and removal of existing sterile medical dressings can exacerbate skin discomfort, especially when the patient's wound requires frequent care. Therefore, we propose a new sterile medical dressing. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a medical sterile dressing film to solve the technical problem that current sterile dressing films need to be frequently torn and replaced during wound cleaning, causing patient discomfort and affecting use.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a medical sterile dressing film, comprising an outer pressure plate, a skin patch, and a dressing sheet. The skin patch has a wound opening in the middle, and a skin adhesive layer is provided on the outer side of the lower surface of the skin patch. A plastic film is adhered to the lower side of the skin patch through the skin adhesive layer. A dressing layer is fixed in the middle of the lower surface of the dressing sheet, and the dressing layer corresponds to the wound opening. A breathing port is provided on the inner side of the outer pressure plate, and an inner pressure ring is provided inside the breathing port.

[0006] In use, the plastic film is torn off and the skin patch is adhered to the patient's skin surface through the lower adhesive layer, aligning the wound with the surgical site. Then, the dressing is adhered to the skin patch through the outer adhesive layer, passing through the wound and fitting the patient's surgical site. When debridement is required, the outer pressure sheet is torn off, and then the dressing is torn outwards. The outer adhesive layer connecting the dressing is adhered to the skin patch. Tearing off the dressing does not cause discomfort to the patient's skin. When frequent debridement is required, this device can effectively reduce patient discomfort. The outer pressure sheet is attached to the upper side of the dressing, and the felt and wool pads are fastened with Velcro. The inner pressure ring presses down on the dressing to ensure a proper fit. The breathing port allows outside air to pass through the non-woven fabric structure of the dressing, maintaining normal gas flow to the wound site and preventing secondary damage caused by complete sealing. Simultaneously, the inner pressure ring presses down on the dressing to ensure a secure connection.

[0007] Preferably, the four corners of the skin patch are arrayed with felt blocks, the four corners of the lower surface of the outer pressing piece are arrayed with prick felt blocks, and the prick felt blocks and the felt blocks form a magic tape.

[0008] Preferably, the lower surface of the dressing piece is provided with an outer adhesive layer, the outer adhesive layer is annular in design, and the outer adhesive layer is attached to the upper surface of the skin patch.

[0009] Preferably, the inner pressing ring is made of rubber material, and the inner pressing ring presses and adheres to the upper surface of the dressing piece.

[0010] Preferably, the dressing piece is composed of a non-woven fabric layer and a breathable waterproof layer, and the material of the non-woven fabric layer is polyurethane adhesive, and the material of the breathable waterproof layer is polyurethane film.

[0011] Compared with the prior art, the utility model has the beneficial effects that:

[0012] 1. The skin patch is designed, the plastic film is torn to adhere the skin patch to the surface of the skin of the patient through the lower skin adhesive layer, the wound part is corresponded to the wound, then the dressing piece is adhered to the skin patch through the outer adhesive layer, the dressing layer passes through the wound to adhere to the wound part of the patient, when debridement is needed, the outer pressing piece is torn, then the dressing piece is torn outward, the outer adhesive layer of the dressing piece is adhered to the skin patch, and tearing does not cause discomfort of the surface of the patient, when the patient needs frequent debridement, the discomfort of the surface of the patient can be effectively reduced by adopting the mechanism.

[0013] 2. The outer pressing piece is designed, the outer pressing piece is adhered to the upper side of the dressing piece, the prick felt blocks and the felt blocks form a magic tape, the inner pressing ring is pressed downward to ensure the adhesion of the dressing piece, the breathing part can make the air of the outside pass through the non-woven fabric structure of the dressing piece, the normal gas circulation of the wound part is maintained, secondary damage of the wound part caused by complete sealing is avoided, and the inner pressing ring is pressed downward to ensure the stable connection of the dressing piece.
