Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, and particularly relates to a PORT pump dressing. Background Art

[0002] In the medical field, long-term intravenous infusion therapy is a common treatment method for many chronic disease patients, cancer patients, and patients in need of continuous nutritional support therapy. The traditional intravenous infusion method often requires frequent punctures of the patient's skin, which not only increases the patient's pain but also may cause risks such as skin damage and infection due to repeated punctures. To solve this problem, PORT pumps (implantable venous infusion ports) have emerged, which allow long-term indwelling in the body and achieve drug infusion through an injection port under the skin and a venous catheter system.

[0003] When using a PORT, a special right-angle needle is required for puncture and infusion. The special design of the right-angle needle allows it to remain indwelling for up to one week after puncture, providing great convenience for long-term treatment. However, after the right-angle needle is inserted, it usually needs to be fixed with a covering film dressing, resulting in long-term compression and friction of the needle wings on both sides of the right-angle needle against the patient's skin, which easily causes skin damage and discomfort, bringing additional pain to the patient. Summary of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a PORT pump dressing to solve the technical problems mentioned in the above background art.

[0005] The utility model provides a PORT pump dressing, which includes a gasket. The gasket is provided with a central hole and a slit. The central hole is located at the center of the gasket.

[0023] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present utility model are given in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present utility model more thorough and comprehensive.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used herein in the description of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0026] Please refer to Figures 1 to 4 , the PORT pump dressing in the first embodiment of the present utility model includes a gasket 10. A central hole 11 and a slit 12 are provided on the gasket 10. The central hole 11 is located at the center of the gasket 10. One end of the slit 12 communicates with the central hole 11, and the other end penetrates through the side edge of the gasket 10. A cover piece 20 is provided on the gasket 10. The cover piece 20 is located on one side of the slit 12. The cover piece 20 can be folded relative to the gasket 10 to cover or expose the slit 12.

[0027] By folding the cover piece 20 of the gasket 10 to expose the slit 12 and clamping it at the lower edge of the right-angle needle, when the position of the central hole 11 is aligned with the puncture point position, the cover piece 20 is reset, so that the gasket 10 is located between the right-angle needle and the patient's skin, effectively relieving the discomfort caused by the long-term compression of the needle wings on both sides of the right-angle needle on the patient's skin.

[0028] Preferably, in this embodiment, the gasket 10 is rectangular in shape, with dimensions of 12*12 cm and is made of medical foam. While effectively relieving the needle wing compression, it also ensures breathability, making it difficult for patients to have allergic reactions. At the same time, the medical foam contains chlorhexidine, which is a disinfectant for reducing catheter-related bloodstream infections, increasing the antibacterial ability of the skin around the puncture point and reducing catheter-related infections in cancer patients.

[0029] It should be noted that in this embodiment, the shape of the gasket 10 can be adjusted as needed to a circular shape or the like. This embodiment is only an example and not a limitation.

[0030] The specific usage method of the PORT pump dressing in this embodiment is as follows: When the medical staff inserts the right-angle needle into the infusion port of the patient, lift the cover piece 20 of the gasket 10 to expose the slit 12, and snap it in from the lower edge of the right-angle needle until the center hole 11 of the gasket 10 is aligned with the puncture point. Then, reset the cover piece 20 so that the gasket 10 is located between the needle wings of the right-angle needle and the patient's skin, blocking the needle wings of the right-angle needle and preventing them from directly contacting the patient's skin for a long time, which may cause discomfort. After the gasket 10 is laid, attach the fixing film 50 to the patient's skin in a tension-free manner, thereby fixing the right-angle needle on the gasket 10. When it is necessary to pull out the right-angle needle, gradually tear the fixing film 50 upward from the lower edge of the right-angle needle, and then remove the gasket 10.

[0031] Further, referring to Figure 2 , in an implementation manner of this embodiment, a hook-and-loop fastener rough surface 31 is provided on the surface of the cover piece 20 facing the gasket 10, and a hook-and-loop fastener hook surface 32 corresponding to the hook-and-loop fastener rough surface 31 is provided on the gasket 10. It can be understood that by cooperating the hook-and-loop fastener rough surface 31 with the hook-and-loop fastener hook surface 32, the cover piece 20 can be adhered to the gasket 10, so that the cover piece 20 and the gasket 10 are combined to form an integral closed loop, effectively preventing the gasket 10 from cracking and wrinkling at the slit 12 when the patient moves, ensuring the overall flatness of the gasket 10, and further ensuring that the needle wings of the right-angle needle are flatly fixed on the gasket 10.

[0032] Further, in another implementation manner of this embodiment, a first adhesive layer is provided on the surface of the cover piece 20 facing the gasket 10, and a first release paper is provided on the first adhesive layer. It can be understood that after tearing off the first release paper, the cover piece 20 can be adhered to the gasket 10 through the first adhesive layer, so that the cover piece 20 and the gasket 10 are combined to form an integral closed loop, achieving the same technical effect as the above-mentioned hook-and-loop fastener.

[0033] Further, referring to Figure 3 , the spacing of the slit 12 gradually increases outward from the center hole 11, presenting a V shape, which is convenient for the slit 12 of the gasket 10 to be aligned and snapped into the lower edge of the right-angle needle.

[0034] Further, referring to Figure 4, the PORT pump dressing further includes a fixing film 50, and a transparent area 51 adapted to the shape of the gasket 10 is provided on the fixing film 50. It can be understood that the fixing film 50 is used to cover the right-angle needle and the gasket 10 and bond them to the patient's skin, ensuring that the right-angle needle and the gasket 10 will not be displaced or fall off due to the patient's activities. Among them, the transparent area 51 is aligned with the gasket 10, facilitating medical staff to observe the puncture point in real time, so as to take nursing measures in time when bleeding, redness and swelling occur.

[0035] Furthermore, a perforation 52 is provided on the fixing film 50. The perforation 52 is used for the catheter of the right-angle needle to pass through, playing a limiting role and improving the fixing effect on the catheter of the right-angle needle.

[0036] It should be noted that when applying the fixing film 50, medical staff should first pass the catheter of the right-angle needle through the perforation 52 and then tear off the release film on the fixing film 50.

[0037] In summary, for the PORT pump dressing in the above embodiment of the present utility model, the covering piece 20 of the gasket 10 is turned over to expose the slit 12, and is clamped from the lower edge of the right-angle needle. When the position of the central hole 11 is aligned with the puncture point position, the covering piece 20 is reset, so that the gasket 10 is located between the right-angle needle and the patient's skin, effectively relieving the discomfort caused by the long-term compression of the needle wings on both sides of the right-angle needle on the patient's skin.

[0038] Please refer to Figure 5 , which shows the PORT pump dressing in the second embodiment of the present utility model. The difference between the PORT pump dressing in this embodiment and the PORT pump dressing in the first embodiment is that: two needle wing fixing bands 40 are symmetrically provided on the gasket 10. A second adhesive layer is provided on the surface of the needle wing fixing band 40, and a second release paper is provided on the second adhesive layer. It can be understood that after the gasket 10 is laid under the right-angle needle, the second release paper is torn off, and the needle wing fixing band 40 is wound around the needle wings of the right-angle needle and bonded to the gasket 10 to strengthen the right-angle needle, ensuring that the two needle wings of the right-angle needle are fixed evenly and stably.
