Description

Technical Field

[0001] This utility model relates to the field of dressing technology, specifically to a dressing with good extensibility and wrinkle prevention. Background Technology

[0002] Dressings are a type of medical product similar to "band-aids." They are commonly used medical consumables for cleaning and bandaging various wounds, promoting wound healing, and are frequently used in modern life.

[0003] For example, patent document CN215652019U discloses an improved dressing, including a dressing body, a first fixation mechanism, and a second fixation mechanism. A thin film is attached to the top of the dressing body, with rounded corners on the four sides. A square opening is provided in the center of the thin film. The fixing tape is X-shaped. The central venous catheter is placed in the center, and the area where the thin film is attached is completely exposed to the air. At this time, medical staff pass a thin tube catheter through the circular opening and fix the catheter with two fixing tapes. The heparin cap of the central venous catheter is fixed by the first and second fixation components, which greatly improves the fixation effect of the central venous catheter and effectively avoids the occurrence of accidental catheter removal.

[0004] The aforementioned device primarily relies on the adhesion between the thin film and the patient's skin to attach the device to the wound surface. However, the adhesive area of ​​the thin film attached to the device is relatively large, and the film is square with multiple corners. Furthermore, the film is a single unit. During use, when medical staff peel off the dustproof paper attached to the adhesive area of ​​the film and then adhere the film to the skin, the large adhesive area of ​​the film makes it easy for local areas to stick together and wrinkle if not handled properly. This reduces the adhesion between the device and the skin. Therefore, we propose a dressing with good elasticity and wrinkle prevention. Utility Model Content

[0005] The purpose of this invention is to provide a dressing with good elasticity and wrinkle resistance to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a dressing with good extensibility and wrinkle resistance, comprising a PU film and a wound dressing assembly, wherein the front end of the PU film is cut with a dividing line, and dustproof paper one is pasted on both sides of the rear end of the PU film, and dustproof paper two is connected to the upper and lower sides of the rear end of the PU film, and the wound dressing assembly is connected to the middle of the rear end of the PU film.

[0007] Furthermore, four dividing lines are provided, mainly for dividing the PU film into four parts.

[0008] Furthermore, the wound dressing assembly includes a dressing layer and an absorbent and breathable cotton layer, and the dressing layer is wrapped inside the absorbent and breathable cotton layer to absorb tissue fluid exudated from the wound.

[0009] Furthermore, a plastic sheet is adhered to both the upper and lower front sides of the PU film to provide a handhold for the user when the PU film is torn.

[0010] Furthermore, plastic sheets two are adhered to both the upper and lower front sides of the PU film, and the cross-section of the plastic sheets two is rectangular.

[0011] Furthermore, a fixing adhesive sticker is adhered to one side of the front end of the PU film, and the cross-section of the fixing adhesive sticker is viewed as a rectangle.

[0012] Furthermore, a spare fixing sticker is attached to the center of the front end of the PU film, and a ventilation hole is provided on the inner side of the front end of the PU film.

[0013] Furthermore, the ventilation holes are provided in multiple locations to allow the skin to breathe and enhance comfort.

[0014] This utility model provides a highly elastic and wrinkle-resistant dressing with the following beneficial effects: The highly elastic and wrinkle-resistant dressing uses dividing lines, allowing the user to tear along these lines during use, thus dividing the PU film into four parts. Each part of the divided PU film is small in size and has fewer rounded corners and edges, making it easier for the user to apply and preventing wrinkles. The absorbent and breathable cotton layer has good absorbency, effectively absorbing tissue fluid exudated from the wound, while the vents allow for ventilation.

[0015] 1. With this utility model, the user can divide the PU film into four parts along the four dividing lines, and a dustproof paper is separately pasted behind each part. Because the pasting area of ​​the divided PU film is small and there are fewer rounded corners and edges, it is easier to control and flatten during the pasting process, thus avoiding wrinkles. At the same time, the absorbent and breathable cotton layer has a certain water absorption property, which can effectively absorb tissue fluid oozing from the wound.

[0016] 2. After using this utility model dressing, the user wraps the dressing layer inside with PU film and then uses adhesive tape to fix the crumpled dressing, making it easy to discard. The dressing is mainly composed of PU film, dustproof paper one, dustproof paper two, and wound dressing components. After the dressing is pasted on the patient's wound, the vent holes allow for ventilation. The PU film is a prior art technology and has good extensibility. Attached Figure Description

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, a stretchable and wrinkle-resistant dressing includes a PU film 1 and a wound dressing component 5. The front end of the PU film 1 is cut with dividing lines 2, and dustproof paper 3 is pasted on both sides of the rear end of the PU film 1. Dustproof paper 4 is attached to the upper and lower sides of the rear end of the PU film 1. The wound dressing component 5 is connected to the middle of the rear end of the PU film 1. There are four dividing lines 2, which are mainly used to divide the PU film 1 into four parts. During use, the user can divide the PU film 1 into four parts along the four dividing lines 2, and a dustproof paper is pasted on the back of each part. The user can then paste them one by one. Because the paste area of ​​the divided PU film 1 is small and there are fewer curved corners and edges, it is easier to control and flatten during the paste process, thus effectively avoiding wrinkles.

[0023] like Figure 1-3 As shown, the wound dressing assembly 5 includes a dressing layer 501 and an absorbent and breathable cotton layer 502. The dressing layer 501 is wrapped with the absorbent and breathable cotton layer 502, which is used to absorb tissue fluid exuded from the wound. The absorbent and breathable cotton layer 502 has a certain water absorption capacity. After the dressing is attached to the outer surface of the wound, it can absorb the tissue fluid exuded from the wound.

[0024] Plastic sheets 6 are glued to the top and bottom sides of the front end of PU film 1 to provide a handhold for the user when PU film 1 is torn. Plastic sheets 9 are glued to the top and bottom sides of the front end of PU film 1, and the cross-section of plastic sheet 9 is rectangular.

[0025] A fixing adhesive patch 7 is attached to one side of the front end of the PU film 1, and the cross-section of the fixing adhesive patch 7 is rectangular. After the dressing is used, similar to existing ones, the rear end of the PU film 1 is provided with medical pressure-sensitive adhesive, which has a certain degree of stickiness. When the dressing is torn off, the stickiness of the medical pressure-sensitive adhesive will decrease. At this time, the user uses the PU film 1 to wrap the dressing layer 501 inside, and then uses the fixing adhesive patch 7 to fix the crumpled dressing, which makes it easy to discard the dressing.

[0026] A spare fixing patch 8 is attached to the middle of the front end of the PU film 1, and a ventilation hole 10 is opened on the inner side of the front end of the PU film 1. Multiple ventilation holes 10 are opened to allow the skin to breathe and enhance comfort. The dressing is mainly composed of PU film 1, dustproof paper 1 3, dustproof paper 2 4 and wound dressing component 5. After the dressing is pasted on the patient's wound, the ventilation holes 10 can play a role in ventilation. At the same time, PU film 1 is existing technology and has good extensibility, which makes it easy to paste.

[0027] In summary, this stretchable and wrinkle-resistant dressing should be used according to... Figure 1 , Figure 3 and Figure 4 As shown, the dressing mainly consists of a PU film 1, a first dustproof paper 3, a second dustproof paper 4, and a wound dressing assembly 5. The PU film 1 has a medical pressure-sensitive adhesive at its rear end, providing a certain degree of stickiness. During use, the user tears along the four dividing lines 2 to separate the PU film 1 into four parts, which can then be pasted one by one. Each time a part is pasted, the dustproof paper at the back is removed, allowing the corresponding PU film 1 to be pasted, thus effectively preventing wrinkles. During use, the absorbent and breathable cotton layer 502 absorbs tissue fluid exudated from the wound, while simultaneously... Figure 2 As shown, the ventilation holes 10 also serve to allow for ventilation. Similar to existing PU film dressings, the PU film 1 also has good extensibility. After the dressing is used, as with existing dressings, the user wraps the dressing layer 501 inside the PU film 1 and then uses the adhesive tape 7 to fix the crumpled dressing, making it easy to discard the dressing.
