Description

Technical Field

[0001] This utility model relates to the field of indwelling needle film technology, specifically an indwelling needle patch. Background Technology

[0002] Currently available indwelling needle films, also known as indwelling needle dressings or transparent indwelling needle dressings, are medical supplies specifically designed to cover and protect indwelling needles (a type of long-term intravenous infusion device). Their main function is to maintain the sterility of the indwelling needle, prevent external contamination, and provide some protection against friction or damage during patient movement. However, in existing indwelling needle films, because the extension tube and the indwelling needle are not aligned, the end of the extension tube needs to be tucked in after application. This can easily lead to edge lifting of the indwelling needle film, resulting in a loose fit and compromised sealing. Furthermore, separating the base layer from the film layer during use is difficult with the fingers, often making it impossible to separate the base layer and film layer in one go. Summary of the Invention

[0003] Therefore, the purpose of this utility model is to provide an indwelling needle patch. Through the indwelling needle patch component, the user can freely choose the opening length of the indwelling needle patch to form an opening without having to wrap the end of the extension tube inside, reducing the probability of the indwelling needle patch peeling off, so that the indwelling needle patch can fit better. Furthermore, through the set misalignment component, it is convenient for the user to use their fingers to separate the base layer from the film layer in one go, making it easy to peel off and use without having to try multiple times.

[0004] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: an indwelling needle dressing, comprising:

[0005] An indwelling needle membrane assembly includes an indwelling needle membrane base layer, an indwelling needle membrane layer adhered to the surface of the indwelling needle membrane base layer, an annular adhesive tape layer adhered to the surface of the indwelling needle membrane layer, and a first tear-resistant line formed on the surface of the indwelling needle membrane layer.

[0006] The misalignment component includes a first connecting piece connected to the side of the annular adhesive tape layer, a first easy-tear line formed on the surface of the first connecting piece, a second connecting piece connected to the side of the indwelling needle film layer, and a second easy-tear line formed on the surface of the second connecting piece.

[0007] In a preferred embodiment of the indwelling needle patch described in this utility model, the first connecting piece and the second connecting piece are staggered and distributed, and the first connecting piece and the second connecting piece are broken by a first tear line and a second tear line, respectively.

[0008] As a preferred embodiment of the indwelling needle patch described in this utility model, it further includes a separation component, which includes a second easy-tear tear line and a third easy-tear tear line formed on the surface of the annular adhesive paper layer;

[0009] The second and third easy-tear fracture lines are of the same length.

[0010] As a preferred embodiment of the indwelling needle patch described in this utility model, it further includes an adhesive component, which includes a substrate adhered to the bottom surface of the indwelling needle patch base layer and an arc-shaped edge disposed at the front end of the substrate.

[0011] In a preferred embodiment of the indwelling needle patch described in this utility model, the substrate is bonded to the indwelling needle patch base layer by adhesive, and the arc-shaped edge is separated from the indwelling needle patch base layer.

[0012] In a preferred embodiment of the indwelling needle patch described in this utility model, the indwelling needle patch layer and the first tear line are transparent.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] With the designed indwelling needle membrane component, users can freely choose the opening length of the indwelling needle membrane to form an opening without having to wrap the end of the extension tube inside, reducing the probability of the indwelling needle membrane peeling off and allowing for better adhesion. In addition, the designed misalignment component makes it easy for users to use their fingers to separate the base layer from the membrane layer in one go, making it easy to peel off and use without having to try multiple times.

[0015] The separation components make it easy to peel off the ring-shaped adhesive layer, and the adhesion components make it easy to stick all the waste scraps together after the film is peeled off, making it easy to dispose of them in one place. This avoids the problem of scraps scattering when thrown into the trash can and having to be picked up and disposed of again, making it more hygienic to use. Attached Figure Description

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] This utility model provides an indwelling needle patch. With the indwelling needle patch component, the user can freely choose the opening length of the indwelling needle patch to form an opening without having to wrap the end of the extension tube inside, reducing the probability of the indwelling needle patch peeling off and allowing the indwelling needle patch to fit better. In addition, the staggered component makes it easy for the user to use their fingers to separate the base layer from the film layer in one go, making it easy to peel off and use without having to try multiple times.

[0026] Figures 1-3 The diagram shown is an overall structural schematic of one embodiment of an indwelling needle patch according to this utility model. Please refer to [link / reference]. Figure 1-3 The main structure of this embodiment includes: an indwelling needle membrane assembly and a misalignment assembly;

[0027] The indwelling needle membrane assembly is designed for better adhesion. Specifically, the indwelling needle membrane assembly includes an indwelling needle membrane base layer 11, an indwelling needle membrane layer 12 adhered to the surface of the indwelling needle membrane base layer 11, an annular adhesive tape layer 13 adhered to the surface of the indwelling needle membrane layer 12, and a first easy-tear tear line 14 formed on the surface of the indwelling needle membrane layer 12.

[0028] In practical use, the user separates the indwelling needle film base layer 11 from the indwelling needle film layer 12 and covers the indwelling needle on the patient's hand with the indwelling needle. During the application process, the user directly tears a long opening through the first easy-tear tear line 14 to facilitate the wiring of the extension tube. This allows the indwelling needle film layer 12 to better adhere to the skin without having to wrap the end of the extension tube inside, reducing the probability of the indwelling needle film peeling off.

[0029] The misaligned component makes it easy for users to peel it off with their hands. Specifically, the misaligned component includes a first connecting piece 21 connected to the side of the annular adhesive tape layer 13, a first easy-tear line 22 formed on the surface of the first connecting piece 21, a second connecting piece 23 connected to the side of the indwelling needle film layer 12, and a second easy-tear line 24 formed on the surface of the second connecting piece 23.

[0030] In actual use, the user pinches the second connecting piece 23 with their fingers and pulls it upward to separate the indwelling needle membrane base layer 11 from the indwelling needle membrane layer 12, making it easy to apply force. After the indwelling needle membrane layer 12 is attached, the user pinches the first connecting piece 21 with their fingers and pulls it upward to peel off the annular adhesive paper layer 13, thus completing the use.

[0031] Furthermore, the separation component facilitates the peeling and separation of the annular adhesive layer 13, and the adhesion component facilitates the adhesion of all waste scraps after the film is peeled off, making it easy to dispose of them in a centralized manner. This avoids the problem of scraps scattering when thrown into the trash can and needing to be picked up and disposed of again, making it more hygienic to use.

[0032] Specifically, it also includes a separation component, which includes a second tear line 31 and a third tear line 32 formed on the surface of the annular adhesive tape layer 13;

[0033] Among them, the second tear line 31 and the third tear line 32 are of the same length;

[0034] In practical use, depending on usage habits, some users are accustomed to peeling off the annular adhesive tape layer 13 directly from the middle. At this time, the second easy-tear tear line 31 and the third easy-tear tear line 32 are distributed to facilitate the user to peel off the annular adhesive tape layer 13 from the middle, thus improving the convenience of use.

[0035] Specifically, it also includes an adhesive component, which includes a substrate 41 adhered to the bottom surface of the indwelling needle membrane base layer 11 and an arc-shaped edge 42 disposed at the front end of the substrate 41.

[0036] The film 41 is bonded to the indwelling needle membrane base layer 11 by adhesive, and the arc-shaped edge 42 is separated from the indwelling needle membrane base layer 11.

[0037] After use, the user can directly peel off the base film 41 through the curved edge 42. After peeling it off, the adhesive area on the bottom surface of the needle-retaining film base 11 will be exposed. At this time, the user can pinch the peeled-off ring-shaped adhesive paper layer 13 and the base film 41 together, and then wrap and stick all the remaining waste materials through the adhesive area on the bottom surface of the needle-retaining film base 11. The user can simply wrap it all up and stick it together, making it easy to discard together and avoiding the situation where it is scattered and cannot be thrown into the trash can at once, making it convenient to use.

[0038] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
