Description

Technical Field

[0001] This utility model relates to the technical field of medical consumables, and in particular to a sterilizable, open-window dressing fixation device with an exudate pad. Background Technology

[0002] In clinical practice, patients frequently experience exudation problems from various wounds, including those at catheter puncture sites. Improper management of wound exudation can easily lead to complications such as skin inflammation and wound infection, causing pain and burden for patients.

[0003] In the existing field of wound dressings, various functional dressings for absorbing exudate have been developed, including hydrocolloid dressings, alginate dressings, polyurethane foam dressings, etc., which solve the problem of exudate to varying degrees, keep the wound dry, and reduce the risk of complications such as infection and dermatitis.

[0004] For wounds with significant exudate, such as lymphatic leakage after PICC catheterization, some medical staff use clever window-opening techniques on dressings and then layer targeted dressings for care. There are also window-opening dressing fixation devices that allow dressing changes to be performed directly through the window opening. Among these, the window-opening dressing change method is more suitable for wounds with large and continuous exudate. A small window is made in the middle of the dressing, and the puncture point is covered with a material or dressing that can absorb the exudate. When changing the dressing, medical staff do not need to remove the dressing; they can change the dressing through the small window, which avoids repeated tearing of the dressing and damage to the skin, and is more convenient for medical staff.

[0005] However, the open-window dressing method is prone to causing seepage that wets the skin at the edges of the open-window dressing. When disinfecting the window, the disinfectant solution can also easily wet the edges of the dressing, which can easily cause dermatitis around the window or cause the dressing to fall off.

[0006] In view of this, the inventors have specifically designed a sterilizable, open-window dressing fixation device with an exudate pad, which leads to this invention. Utility Model Content

[0007] The purpose of this invention is to provide a sterilizable windowed dressing fixation device with an exudate pad. This invention solves the problems of existing windowed dressings being prone to leakage, causing skin damage or dressing loosening, as well as the cumbersome operation of cutting windowed dressings by oneself.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A sterilizable, open-window dressing fixation device with an exudate pad includes a basement membrane dressing layer, an exudate pad layer, a waterproof material layer, and two release papers; the inner side of the basement membrane dressing layer is adhesive and has an opening in the middle; the exudate pad layer is fixedly disposed on the opening in the middle of the basement membrane dressing layer and also has an opening in the middle; the waterproof material layer is fixedly disposed on the outer side of the basement membrane dressing layer and also has an opening in the middle; the opening in the middle of the waterproof material layer communicates with the opening in the middle of the exudate pad layer; the two release papers cover the inner sides of the basement membrane dressing layer and the exudate pad layer.

[0010] Furthermore, the waterproof material layer is annular in shape.

[0011] Furthermore, the waterproof material layer is thicker at the edges and thinner in the middle.

[0012] Furthermore, the number of release papers is two.

[0013] Furthermore, the release paper symmetrically covers the inner side of the base film dressing layer and the permeation pad layer.

[0014] Furthermore, the outer edge of the release paper is larger than the outer edge of the base film dressing layer.

[0015] Furthermore, the edge of the opening in the middle of the seepage pad layer is aligned with the edge of the opening in the middle of the waterproof material layer.

[0016] Furthermore, the outer edge of the basement membrane dressing layer is rectangular.

[0017] After adopting the above technical solution, the present invention has the following beneficial effects:

[0018] 1. This utility model consists of four parts: a basement membrane dressing layer, an exudate pad layer, a waterproof material layer, and two release papers. The basement membrane dressing layer has an opening in the middle and an adhesive inner side for adhering to the skin; the exudate pad layer is fixed at the opening of the basement membrane dressing layer to absorb fluid oozing from the wound; the waterproof material layer is located on the outermost side and also has an opening corresponding to the exudate pad layer, which serves to prevent external liquid from entering and keep the inside dry.

[0019] 2. Compared to traditional self-cut windowed dressings, this invention offers the advantages of simple and quick operation. The inner seepage pad of this windowed dressing enhances its leak-proof effect, keeping the local skin dry. The innovative micro-recessed design of the outer waterproof material facilitates disinfection and makes it easier to fill and secure the dressing at the window. In terms of design, compared to various windowed dressing devices, this dressing is simple in structure and easy for medical staff to operate. This invention can also be cleverly combined with different functional dressings for targeted care of seepage wounds.

[0020] 3. In this utility model, two release papers are symmetrically covered on the inner side of the base film dressing layer and the permeation pad layer, and the outer edge of the release paper is larger than the outer edge of the base film dressing layer, which facilitates the operation when removing the release paper.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] It should be noted that in this utility model, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element of this utility model must have a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] Please see Figures 1 to 4A sterilizable, ventilated dressing fixation device with an exudate pad includes a basement membrane dressing layer 1, an exudate pad layer 2, a waterproof material layer 3, and release paper 4. The basement membrane dressing layer 1 has an adhesive inner side and an opening in the middle, serving as a framework for the central structure. The exudate pad layer 2 is fixedly disposed on the opening in the middle of the basement membrane dressing layer 1 and also has an opening in the middle. The exudate pad layer 2 absorbs exudate from the window to keep the skin dry and reduce the possibility of dressing loosening. The waterproof material layer 3 is fixedly disposed on the outer side of the basement membrane dressing layer 1 and has an opening in the middle. The waterproof material layer 3 serves to prevent exudate from flowing out and to provide dressing filling. The opening in the middle of the waterproof material layer 3 communicates with the opening in the middle of the exudate pad layer 2, and the communication between the two openings is used for alignment and adhesion to the wound. The release paper 4 covers the inner sides of the basement membrane dressing layer 1 and the exudate pad layer 2, and the release paper 4 is used to protect the adhesive surface of the basement membrane dressing layer 1.

[0030] Preferably, the waterproof material layer 3 is annular, with an opening in the middle of the annulus for aligning with the wound.
