Description

Technical Field

[0001] This utility model relates to the field of medical care products technology, specifically to an infusion port puncture patch with a catheter connector fixing device. Background Technology

[0002] Treatment for hematological malignancies primarily involves chemotherapy. While chemotherapy drugs are effective in treating the disease, they also damage the patient's veins. In recent years, infusion ports have become increasingly popular among cancer patients due to their ability to reduce vascular damage from chemotherapy drugs and their ease of routine maintenance, making them one of the most important central venous catheters in clinical practice. When using an infusion port, a specialized butterfly-shaped atraumatic needle is required for insertion and infusion. Infusion port bases come in various sizes, and because the base is located subcutaneously at varying depths, nurses often struggle to pinpoint the location during insertion, leading to multiple punctures, increased consumable usage, patient discomfort and pain, and potential conflicts between medical staff and nurses. After insertion, the butterfly needle can remain in place for up to a week, during which time a protective dressing is used to isolate the puncture site from air and reduce the risk of infection or even retrograde infection. However, prolonged pressure and friction from the needle wings on the skin can easily cause skin damage and discomfort. Therefore, gauze needs to be placed under the needle wings after insertion to reduce local skin irritation and increase patient comfort. In clinical practice, this is usually done by manually cutting the gauze and placing it under the needle wings. Cutting can result in excessive lint, incorrect size, and other issues. Manual cutting also increases operation time and nurses' workload. It is also detrimental to routine local observation of non-traumatic needle puncture sites. Utility Model Content

[0003] This invention provides an infusion port puncture patch with a catheter connector fixing device, which can solve the problem that existing puncture patches usually only have simple fixing and protection functions, cannot effectively fix the catheter connector, and are prone to butterfly needle dislodgement and displacement, increasing the risk of infection and affecting patient comfort.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a port-of-care puncture dressing with a catheter connector fixing device, comprising a substrate, a first dressing layer disposed on one side of the substrate, and a connector fixing assembly disposed on the upper side of the substrate; a transparent antibacterial layer and a first adhesive layer disposed at the bottom of the first dressing layer, the transparent antibacterial layer being made of chlorhexidine gluconate, and a puncture hole for a butterfly needle to pass through the transparent antibacterial layer; graduation marks corresponding to various sizes of port-of-care dressings disposed on the upper side of the first dressing layer; and a second dressing layer disposed on the first dressing layer. On one side of the dressing layer, after the butterfly-shaped needle is aligned with the infusion port, the second dressing layer covers and secures the butterfly-shaped needle. The connector fixing assembly includes a fixing seat that is attached to the upper side of the substrate. One end of the fixing seat is rotatably provided with a strap for fixing the infusion tube connector. The upper surface of the strap is provided with snap teeth. The other end of the fixing seat is provided with an elastic buckle corresponding to the strap. This effectively fixes the catheter connector, reduces skin irritation, lowers the risk of infection, improves patient comfort and nursing efficiency, and has significant clinical application value.

[0005] Preferably, a second adhesive layer is provided on one side of the second dressing layer, which allows the second dressing layer to cover the butterfly needle head and adhere to the skin. A recording label for recording the time is provided on the other side of the second dressing layer, which is used to record the replacement time for easy subsequent maintenance.

[0006] Preferably, the bottom of the elastic buckle is provided with a buckle channel that engages with the buckle teeth, and the top of the elastic buckle is provided with a curved part, which facilitates operation by medical staff to open the elastic buckle and the strap buckle.

[0007] Preferably, the first dressing layer and the second dressing layer are transparent films, and the area of ​​the second dressing layer is larger than that of the first dressing layer, which secures the butterfly needle, reduces the frequency of replacement, and reduces the nursing burden.

[0008] Preferably, the diameter of the puncture hole is 5 mm.

[0009] Preferably, the first dressing layer is provided with a through hole that matches the puncture hole, so as to facilitate puncture by medical staff.

[0010] Preferably, the transparent antibacterial layer is a gel-like substance with a jelly-like texture, which is breathable and soft. It is placed under the butterfly wing needle tip to reduce the pressure and friction of the needle wing on the skin, avoid skin damage, and improve patient comfort.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] With a simple structure and convenient operation, this device features a transparent antibacterial layer beneath the first dressing layer, providing cushioning protection below the butterfly needle wings. This reduces pressure and friction on the skin, preventing skin damage and improving patient comfort. The transparent antibacterial layer, made with chlorhexidine gluconate, has antibacterial properties and effectively prevents puncture site infection, especially suitable for cancer patients with decreased white blood cell counts after chemotherapy, reducing the risk of retrograde infection. The first dressing layer has graduations corresponding to various infusion port sizes, helping nurses quickly and accurately locate the puncture point, reducing the possibility of multiple punctures and minimizing patient discomfort. A catheter connector fixing device securely fixes the infusion tubing connector, preventing it from dislodging or shifting due to patient movement or external pulling. This addresses the problem that existing puncture dressings typically only provide simple fixation and protection, failing to effectively secure the catheter connector, leading to butterfly needle dislodgement or shifting, increased infection risk, and reduced patient comfort.
