Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a dressing for fixing a catheter for HAIC treatment. Background Art

[0002] Hepatic arterial infusion chemotherapy (HAIC) is a form of interventional therapy for liver cancer. It involves a catheter inserted through a femoral artery puncture, where chemotherapy drugs are continuously infused into the tumor's blood supply artery over a long period of time. Simply put, HAIC involves injecting chemotherapy directly into the hepatic artery. It offers the advantages of minimally invasiveness, safety, high efficacy, and high reproducibility, as well as high local tumor control rates and minimal systemic side effects.

[0003] Compared to traditional infusion management, HAIC places more stringent demands on medical staff for line care due to its continuous drug delivery method. There is also a lack of standardized care methods in HAIC line management. Currently, traditional methods generally use a combination of dressings and tape to fix the lines. Traditional HAIC treatment involves multiple interventional treatment methods, such as femoral artery and radial artery. Different medical staff also have differences in operation, resulting in inconsistent line management and, consequently, differences in HAIC care outcomes.

[0004] In this regard, the inventors propose a catheter-fixed dressing for HAIC treatment that can achieve standardized operations, so as to provide standardized and standardized operating conditions for clinical nurses, aiming to eliminate or reduce the nursing differences caused by differences in experience and skills among clinical nurses.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0022] See also Figure 1-Figure 5 This embodiment provides a HAIC treatment catheter fixing dressing, including a dressing body 101. The back of the dressing body 101 is provided with an adhesive layer and a release layer.

[0023] The dressing body 101 is provided with a concave area 102 defined as a puncture area, and a first secondary patch 103 is provided on the upper side of the concave area 102 for attaching the catheter sheath to the skin and fixing it;

[0024] At least two tear lines are arranged in parallel and laterally spaced on the lower side of the dressing body 101, and at least one tear line is arranged laterally to the left of the tear line on the lower side on the upper side of the dressing body 101.

[0025] This product is used to standardize catheter fixation during HAIC treatment, thereby reducing the confusion caused by different medical staff using traditional multiple sets of dressings and adhesive tapes to fix the catheter. Specifically:

[0026] The adhesive layer is divided into several independent adhesive areas by the transverse division of the tear line and the regional division of the first secondary patch 103, and each independent adhesive area is provided with an independent release layer. In this embodiment, two tear lines are provided on the lower side of the dressing body 101, and one tear line is provided on the lower side. Figure 2 As shown, five groups of areas AE are formed.

[0027] For example, in the HAIC pipeline of the femoral artery, this product is used. First, the release layer of the A and C areas is torn off to determine the puncture site. The concave part is set at the puncture site. The product is pasted in the A, C, and D areas. Then the concave area 102 is punctured. After the puncture is completed, when the catheter is fixed in an S-shape: the second tear line 104 on the lower side is torn to a suitable width, and the catheter is bent and inserted into the bottom layer. At this time, the release layer of the E area is torn off and pasted to the skin to achieve the fixation of the first curved pipe section. Similarly, the second curved pipe section is fixed in the B area. Figure 3 shown.

[0028] At the same time, since at least two tear lines are set on the lower side, it can be adapted to the interventional fixation of the HAIC microcatheter, so that the catheter and the microcatheter can be coiled and fixed. According to the above, similarly, the first tear line 103 and the second tear line 104 on the lower side are torn to a suitable width (the D area is not adhered in advance), and after the catheter and the microcatheter are coiled, they are inserted through one tear line, and the head of the complete catheter protrudes and is exposed to the other tear line, and the D and E areas are pasted to fix the coiled catheter and the microcatheter. After tearing the third tear line 105 in the B area to a suitable width, the catheter head end is inserted into the lower side through the third tear line 105 and inserted out from the upper edge, and the release layer in the B area is torn off and pasted to complete the fixation of the HAIC pipeline with the microcatheter. Figure 4 shown.

[0029] Similarly, when performing HAIC interventional catheter fixation of the radial artery, for example, when the exposed catheter is fixed in a U-shape, the first bend section is fixed as described above, and then the third tear line 105 is torn to a suitable width, and the catheter tip is inserted into the lower side through the third tear line 105 and then inserted out from the upper edge, and the release layer in the B area is torn off and pasted, thus completing the fixation of the exposed pipeline. Figure 5 shown.

[0030] After the exposed pipeline is fixed as described above, the catheter sheath is further covered and fixed with a first secondary patch 103 to ensure the fixation of the catheter sheath and prevent it from moving and falling off.

[0031] As can be seen from the above, the product can realize various fixation methods of the radial artery and femoral artery under ordinary catheters or microcatheters in HAIC pipeline fixation care. The pipeline can also be set in various ways such as U-shape, S-shape and curved coiling. In practice, medical staff can select the fixation method based on the actual training needs of the hospital and the actual needs of the patients, which is convenient for standardized management of in-hospital care. Compared with the traditional method of combining multiple sets of elastic dressings and adhesive tapes, it is more unified in pipeline fixation, nursing methods, and operation positioning management, and is more convenient for standardized medical training and pipeline care operations.

[0032] In this embodiment, since HAIC is a long-term interventional treatment, the time for inserting the tube is relatively long, so there may be bleeding at the puncture site. Therefore, in this product, the first sub-patch 103 is provided with a hole 107, and the hole 107 is used to be set in the puncture point position area so that the puncture point can be exposed. A second sub-patch 108 is provided on the lower side of the concave area 102, and the end of the second sub-patch 108 is provided with a plurality of tear lines (fourth tear lines 109) set at intervals. An independent release layer is provided in the area between the interval tear lines. Sterile gauze can be fitted under the second sub-patch 108 to fit in the hole 107 area and contact the puncture point position to achieve adsorption care for bleeding. In this structure, due to the plurality of tear lines set at intervals, an independent release layer is provided in the area between the interval tear lines, which can be torn off from the release layer at the end in turn. When the sterile gauze needs to be replaced, the tear line at the end is torn off, and the adhesive area of ​​a group of positions is used for pasting, thereby realizing multiple replacement care of the gauze.

[0033] In this embodiment, the dressing patch main body 101 is provided with a covering patch 110 for covering the exposed pipeline on the upper layer. The covering patch 110 is provided with a tear line (fifth tear line 111) for exposing the pipe joint to the outside. As in the above-mentioned S-shaped pipeline fixing method, the pipe joint is passed through the sixth tear line to the outside to further fix the exposed pipeline.

[0034] In this embodiment, the dressing body 101 and the cover patch 110 are both made of transparent material. One side of the cover patch 110 is fused and adhered to one side of the dressing body 101, and the other side protrudes from the side of the dressing body 101.

[0035] The above contents described in this specification are merely examples of the present invention. Those skilled in the art of the present invention may make various modifications, additions, or substitute similar methods to the specific embodiments described, as long as they do not deviate from the contents of this specification or exceed the scope defined by the claims, and shall fall within the scope of protection of the present invention.
