Description

Technical Field

[0001] The utility model belongs to the technical field of postoperative dressing, and specifically relates to a special dressing film assembly for HAIC postoperative use. Background Technique

[0002] HAIC mainly utilizes the principle of arterial chemotherapy to directly insert a catheter into the blood supply vessel of the tumor, continuously inject chemotherapy drugs into the tumor through the catheter, and then kill the tumor with the chemotherapy drugs. The specific operation method of HAIC treatment has the following steps: puncture the radial artery or femoral artery to establish a small tunnel, and then insert a catheter through this femoral artery or radial artery into the hepatic artery. At this time, angiography is performed in the hepatic artery to observe the blood vessel distribution in the liver; according to the arterial blood supply of the tumor, the catheter is selectively placed into the tumor blood supply artery; chemotherapy drugs are injected through the catheter. According to the medication principle of HAIC, the chemotherapy drugs can be injected into the patient's body for several days continuously, which can significantly increase the total dose of chemotherapy drugs and prolong the time of "killing cancer cells" with high-concentration chemotherapy drugs, producing a high-efficiency anti-cancer effect.

[0003] After the operation, it is necessary to retain the femoral artery sheath and catheter, and a microcatheter may be indwelled if necessary, and the patient is taken back to the ward for chemotherapy drug injection treatment. After the patient returns to the ward, chemotherapy drug injection will be given to the patient through the catheter for several hours or even longer. Therefore, the dressing of the arterial sheath tube after the operation is very important for ensuring the patency of the subsequent pipeline and the safe use of chemotherapy drugs. The existing dressing methods generally use transparent dressings or surgical dressings for pasting and fixing, usually using 3 to 4 transparent dressings or surgical dressings, which increases the consumption cost of surgical materials. In addition, there are problems such as the sheath tube, catheter, and microcatheter pipelines being in a mess, the fixed dressing being unstable and easy to fall off, and the dressing storage effect being limited and unable to effectively store the catheter, resulting in catheter folding or twisting, affecting the patency of the catheter and increasing the risk of catheter damage and blockage.

[0004] Some patents of postoperative sterile dressing films are disclosed in the prior art. Among them, the invention patent with the publication number of CN116019635A discloses a special sterile dressing film kit for HAIC postoperative use, including a fixed dressing applied to the puncture site and a storage dressing for storing the catheter. The fixed dressing pastes and fixes the blood vessel sheath and the blood vessel sheath connecting tube on the human body surface, and a storage cylinder for winding the catheter on its surface is fixedly installed on the storage dressing. Although it solves the problems of increasing the consumption cost of surgical materials and the catheter being in a mess and easy to fall off, there are still problems such as the sheath tube, catheter, microcatheter, etc. being exposed to the outside, still being prone to catheter displacement or damage caused by clothes or external forces, the displaced catheters being in a mess, and the amount of dressings used being relatively large.

[0005] In view of this, the inventor of the present invention has conducted in-depth research on the need to facilitate operation and prevent the fixed catheter from being contacted and rubbed by clothes and other objects, thus resulting in this case. Summary of the Utility Model

[0006] To overcome the problems in the prior art that the catheter after postoperative fixation is cumbersome to operate and may be displaced, damaged or detached due to contact with clothes and / or external forces, the present utility model provides a special dressing film assembly for HAIC postoperative use, which includes a sterile dressing applied to the puncture site after HAIC operation on the human body surface and a concave protective cover integrally connected to the sterile dressing. The protective cover is connected to the long side of the sterile dressing, and a demarcation groove is provided at the connection between the protective cover and the sterile dressing. The protective cover can be opened and closed with the sterile dressing along the demarcation groove, and the protective cover can completely cover the sterile dressing.

A protective cover is provided above the sterile dressing to prevent the catheter and connector placed above the sterile dressing from being affected by clothes or external forces during subsequent chemotherapy, resulting in catheter displacement or damage. A demarcation groove is provided between the sterile dressing and the protective cover to ensure smooth opening and closing between the two. When the two are closed, the sterile dressing below will not be lifted by the protective cover, ensuring stable fixation between the sterile dressing and the skin. In addition, the sterile dressing is only composed of a fixed dressing and a storage dressing. After the operation, only one dressing film is needed to complete the subsequent treatment of the puncture site, with simple operation, fewer dressing films used compared to the prior art, no need to waste more dressing films for pasting, saving costs, and providing a better nursing and treatment experience for postoperative patients.
