Description

Technical Field

[0001] The utility model relates to the technical field of medical dressings, and specifically refers to a deep vein catheter removal dressing. Background Technique

[0002] Clinical deep vein catheter removal is an important medical operation, mainly involving safely removing the deep vein catheter (such as CVC catheterization, PICC catheter, infusion port, etc.) inserted into the patient's body from the blood vessel. Clinical deep vein catheter removal is a medical process that requires highly professional skills and strict aseptic operation. The dressing treatment after deep vein catheter removal is a link in deep vein catheterization nursing, aiming to reduce the risk of infection and promote the healing of the puncture site.

[0003] The CVC catheter can generally be indwelled for 2 - 4 weeks, while the PICC catheter can be indwelled for up to one year for patients. Due to the long indwelling time, there may be the formation of a fistula tract. After directly removing the deep vein, it is impossible to prevent air from entering the deep vein after pressing with a cotton swab for 15 minutes, and there is a risk of air embolism. When the patient washes the skin near the puncture site after removing the deep vein, there may be water leakage to the puncture site, and there is a risk of infection. Some existing medical dressings do not have a transparent hydrogel dressing, do not have the function of promoting the healing of the puncture site, cannot be directly used during removal, have general adhesiveness and are prone to curling during use, and cannot observe the situation of the puncture site. Moreover, the dressing replacement cost is high, does not have a compression function, is prone to soaking the wound during use, and is not suitable for use after the patient is discharged. Content of the Utility Model

[0004] The utility model provides a deep vein catheter removal dressing to solve the problems that the above-mentioned traditional medical dressings are not suitable for use after deep vein catheter removal, have a high dressing replacement cost, do not have a compression function, are not conducive to the healing of the puncture site, and are not suitable for use after the patient is discharged.

[0005] To solve the above technical problems, the technical solution provided by the utility model is: a deep vein catheter removal dressing, which sequentially includes a waterproof transparent film layer, a silica gel patch, a gel layer, and a release layer from the outside to the inside. The gel layer is a transparent hydrogel dressing, which can promote wound healing, absorb exudate, and have an antibacterial effect while facilitating the observation of the wound condition. Both the silica gel patch and the gel layer have a certain thickness, and can play a certain compression role during use, enabling the wound to heal better, preventing air from entering, and avoiding the formation of air embolism. The waterproof transparent film layer has the same shape as the silica gel patch and is fixed on the upper surface of the silica gel patch. The release layer is bonded to the lower surfaces of the silica gel patch and the gel layer. A round groove is provided under the silica gel patch, and the gel layer is bonded in the round groove and protrudes from the lower surface of the silica gel patch. An air-permeable mechanism is provided inside the silica gel patch to discharge the gas between the silica gel patch and the gel layer and maintain the air permeability between the silica gel patch and the skin. A pressure-increasing mechanism for assisting in pressing and stopping bleeding is provided between the silica gel patch and the gel layer.

[0006] As an improvement, the silicone patch has a special-shaped structure, and the four corners of the silicone patch extend outward. The area of the release layer is larger than the bonding coverage area of the silicone patch.

[0007] As an improvement, the ventilation mechanism includes a number of through holes that communicate with each other. The through holes are evenly distributed on the side surface of the silicone patch. A number of air holes communicating with the through holes are provided under the silicone patch. Part of the air holes are circumferentially distributed outside the circular groove, and the other part of the air holes are distributed at the intersections of the through holes. On the one hand, the air holes can discharge the air existing due to the thickness difference between the silicone patch and the gel layer during the fixing process of the silicone patch. On the other hand, the air holes can maintain the breathability of the silicone patch and improve the comfort of the skin.

[0008] As an improvement, the pressurizing mechanism includes a pressing plate fixed under the silicone patch. The pressing plate is a transparent plastic shell. The pressing plate is located at the center of the circular groove. A groove is provided on the upper surface of the gel layer, and the pressing plate is snap-fitted in the groove.

[0009] The advantages of the present utility model are as follows: 1. From the outside to the inside, there are a waterproof transparent film layer, a silicone patch and a gel layer. After the deep vein is removed, only the transparent hydrogel dressing of the dressing needs to be pressed with the puncture point as the center, and there is no need to use a cotton swab. The gel layer composed of the transparent hydrogel dressing can promote wound healing, absorb exudate, and play an antibacterial role while facilitating the observation of the wound condition;

[0010] 2. The silicone patch and the gel layer have a certain thickness and can play a certain pressing role during use. The provided hard disk can further increase the pressure of the silicone patch on the wound, so that the wound heals better. The gel layer can prevent air and water from entering the wound, and can prevent the occurrence of air embolism and wound infection;

[0011] 3. The provided air holes can, on the one hand, discharge the air existing due to the thickness difference between the silicone patch and the gel layer during the fixing process of the silicone patch. On the other hand, the air holes can maintain the breathability of the silicone patch and improve the comfort of the skin. BRIEF DESCRIPTION OF THE DRAWINGS
