Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical supplies technology, and more specifically, it relates to an infusion port patch. Background Technology
[0002] An infusion port is a completely implanted closed infusion device that consists of a catheter tip located in the superior vena cava and an injection port implanted under the skin. After surgically installing and fixing the infusion port under the patient's skin, a specially designed non-invasive needle is inserted into the port to provide a long-term venous access. Compared to traditional injection methods, infusion ports effectively reduce the number of vascular punctures, lowering the risk of infection and protecting blood vessels, thus preventing complications such as vasculitis. During the use of an infusion port, a transparent membrane should be applied to keep the wound and injection port area clean and dry, avoiding friction against the skin around the port, which could thin or even break the skin, exposing the port and catheter and causing infection or catheter damage.
[0003] Existing transparent films are typically adhered directly to the skin outside the infusion port. During adhesion, excessive air bubbles may form on the film, weakening its protective effect. Therefore, this paper studies and improves upon existing structures and shortcomings to provide an infusion port film with greater practical value. Utility Model Content
[0004] The purpose of this invention is to provide an infusion port dressing, in which the foam dressing layer is adhered to the skin around the infusion port through an outer adhesive film and an inner adhesive film to elevate it, thus avoiding bulging caused by excessive protrusion of the infusion port from the surrounding skin during the adhesion of the transparent film.

[0006] As a preferred technical solution, the foam dressing layer is made of polyester foam or polyurethane foam and has several air pores.
[0007] As a preferred technical solution, the upper surface of the foam dressing layer is provided with a mesh pattern.
[0008] As a preferred technical solution, the foam dressing layer is provided with a buckle for fixing the infusion tube, and the foam dressing layer has a notch in the part corresponding to the buckle for the infusion tube to extend out and be snapped into the buckle.
[0009] As a preferred technical solution, the foam dressing layer, the outer adhesive film, and the inner adhesive film are all provided with an opening slit, and the buckle is divided into a left buckle and a right buckle, which are located on the foam dressing layer on the left and right sides of the opening slit, respectively.
[0010] One of the further technical solutions of this utility model is that the opening is opened along the radius of the foam dressing layer, the outer adhesive film and the inner adhesive film, and is located on the same radius.
[0011] A further technical solution of this utility model is: the opening slit is opened along the diameter of the foam dressing layer, the outer adhesive film and the inner adhesive film, and is located on the same diameter, which divides the foam dressing layer, the outer adhesive film and the inner adhesive film into a two-part structure.
[0012] As a preferred technical solution, the upper surface of the foam dressing layer is provided with a tearable protective film.

[0026] Example 1:
[0027] As attached Figure 1 To be continued Figure 4 As shown, this utility model provides an infusion port dressing, including a frustum-shaped foam dressing layer 1, with a through hole 2 at the center of the foam dressing layer 1 to expose the infusion port, an outer adhesive film 3 connected to the outer periphery of the bottom end of the foam dressing layer 1, and an adhesive layer covering the lower surface of the outer adhesive film 3; an inner adhesive film 4 connected to the inner periphery of the bottom end of the through hole 2, and an adhesive layer covering the lower surface of the inner adhesive film 4.
[0028] In this embodiment, the lower surfaces of the foam dressing layer 1, the outer adhesive film 3, and the inner adhesive film 4 are all provided with a tearable release paper 5. The release paper 5 can protect the outer adhesive film 3 and the inner adhesive film 4, preventing them from losing their adhesiveness due to contact with the outside world when the foam dressing layer 1 is not in use.
[0029] In this embodiment, the foam dressing layer 1 is made of polyester foam or polyurethane foam, which has several pores and good breathability, allowing the skin in contact with the foam dressing layer 1 to breathe better.
[0030] In this embodiment, the upper surface of the foam dressing layer 1 is provided with a tearable protective film 4 to prevent dust and other foreign objects from entering the vent holes when the foam dressing layer 1 is not in use.
[0031] In this embodiment, the upper surface of the foam dressing layer 1 is provided with a mesh pattern, which makes it easy to peel the protective film and the transparent film off the foam dressing layer 1.
[0032] In this embodiment, the foam dressing layer 1 is fitted with a buckle 6 for fixing the infusion tube. The foam dressing layer 1 has a notch 7 in the part corresponding to the buckle 6 for the infusion tube to extend out and be snapped into the buckle. This design facilitates the stable fixing of the infusion tube.
[0033] The foam dressing layer 1, the outer adhesive film 3, and the inner adhesive film 4 are all provided with an opening slit 8. The opening slit 8 is opened along the radius of the foam dressing layer 1, the outer adhesive film 3, and the inner adhesive film 4, and is located on the same radius.
[0034] The buckle 6 consists of a left buckle 601 and a right buckle 602, which are located on the foam dressing layer 1 on the left and right sides of the opening slit 8, respectively. This design increases the convenience of securing the infusion tube.
[0035] The working principle of this embodiment is as follows: When the infusion port dressing is needed, firstly, the release paper 5 on the bottom side and the protective film on the top side are peeled off. Then, the foam dressing layer 1 is adhered to the skin around the infusion port through the outer adhesive film 3 and the inner adhesive film 4, so that the infusion port is located in the through hole 2. Then, the infusion tube is passed through the opening slit 8, protrudes from the notch 7 and is secured in the buckle 7. Then, a transparent film is adhered to the outer surface of the infusion port dressing to complete the use of the infusion port dressing.
[0036] Example 2:
[0037] like Figure 5 and Figure 6As shown, unlike Embodiment 1, the opening slit 8 is formed along the diameter of the foam dressing layer 1, the outer adhesive film 3, and the inner adhesive film 4, and is located on the same diameter, dividing the foam dressing layer 1, the outer adhesive film 3, and the inner adhesive film 4 into a two-part structure. This design facilitates more flexible bonding during use.
[0038] In this invention, the foam dressing layer 1 is adhered to the skin around the infusion port by the outer adhesive film 3 and the inner adhesive film 4 to elevate it, thus avoiding bulging caused by excessive protrusion of the skin around the infusion port during the adhesion of the transparent film.
[0039] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
