Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a special film for an infusion port. Background Art

[0002] The infusion port is a closed infusion device that is completely implanted in the human body. It includes a catheter part with the tip located in the superior vena cava and an injection seat buried subcutaneously. When the infusion port is infused, a layer of film needs to be attached to the skin surface to protect the wound and fix the butterfly needle.

[0003] After searching, the patent number is CN219743546U, and the name is a utility model of a special film for infusion port needle placement, which includes a first film, a first release paper arranged under the first film, and a ring-shaped non-woven fabric arranged at the center of the first film. Through research and analysis, it is found that although it has advantages such as easy use during use, it still has the following disadvantages to a certain extent.

[0004] For example, the film does not have a limiting function. During use, the tail end of the infusion needle cannot be limited and fixed, which causes the tube of the infusion needle to easily move inside the film when the patient moves, thereby affecting the adhesion of the film and causing the film to easily fall off. In order to solve the above technical problems, we have designed a special film for the infusion port. Utility Model Content

[0005] The utility model aims to provide a special film for an infusion port, which has the advantages of limiting function and wear-resistant function, and solves the problem that the existing film cannot limit and fix the tail end of the infusion needle during use, and the wear resistance of the film surface is poor and it is easy to wear.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a special film for an infusion port, comprising a protective film and a first medical tape, wherein a wear-resistant layer is laminated to the top of the protective film, a second medical tape is sewn to the right side of the first medical tape, a rubber block is fixedly connected to the bottom of the second medical tape, and a tube groove is provided at the bottom of the rubber block.

[0007] Preferably, the wear-resistant layer comprises a polyester film layer, the polyester film layer is bonded to the top of the protective film, the top of the polyester film layer is bonded to a TPU film layer, and the top of the TPU film layer is bonded to a nylon film layer.

[0008] Preferably, a first release film is attached to the bottom of the first medical tape, and the bottom of the protective film is attached to the first release film.

[0009] Preferably, a second release film is attached to the bottom of the second medical tape, and the edge of the protective film is fixedly connected to the first medical tape.

[0010] Preferably, an adhesive layer is bonded to the inner wall of the tube groove, and a third release film is bonded to the bottom of the adhesive layer.

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

[0012] 1. The utility model has the advantage of a limiting function through the cooperation of the second medical tape, the rubber block and the tube groove. The third release film and the second release film are peeled off, and the bottom of the adhesive layer is bonded to the pipeline. At this time, the pipeline is located in the inner cavity of the tube groove, and then the second medical tape is bonded to the patient's skin surface. Under the action of the rubber block and the tube groove, the pipeline can be limited and fixed to avoid displacement.

[0013] 2. The utility model has the advantage of strong wear resistance through the cooperation of the polyester film layer, the TPU film layer and the nylon film layer. When friction occurs between the surface of the protective film and foreign objects, the polyester film layer, the TPU film layer and the nylon film layer protect the protective film, making it less likely to be worn, thereby improving the protective effect on wounds.

[0020] See also Figure 1-Figure 5A special film for an infusion port includes a protective film 1 and a first medical tape 2. A wear-resistant layer 3 is attached to the top of the protective film 1. A second medical tape 4 is sewn to the right side of the first medical tape 2. A rubber block 5 is fixedly connected to the bottom of the second medical tape 4. A pipe groove 6 is opened at the bottom of the rubber block 5.

[0021] See also Figure 1 and Figure 2 The wear-resistant layer 3 includes a polyester film layer 7, which is bonded to the top of the protective film 1. A TPU film layer 8 is bonded to the top of the polyester film layer 7, and a nylon film layer 9 is bonded to the top of the TPU film layer 8. The material of the polyester film layer 7 is polyester film, the material of the TPU film layer 8 is TPU film, and the material of the nylon film layer 9 is nylon film. By providing the nylon film layer 9, the wear resistance of the surface of the protective film 1 can be improved, making it less susceptible to wear, thereby increasing the protective effect on wounds.

[0022] See also Figure 3 The bottom of the first medical tape 2 is adhered to the first release film 10, and the bottom of the protective film 1 is adhered to the first release film 10. By setting the first release film 10, the bottom of the first medical tape 2 and the protective film 1 can be protected from dust to prevent dust from sticking and affecting their bonding performance.

[0023] See also Figure 3 A second release film 11 is attached to the bottom of the second medical tape 4 , and the edge of the protective film 1 is fixedly connected to the first medical tape 2 .

[0024] See also Figure 4 The inner wall of the pipe groove 6 is bonded with an adhesive layer 12, and the bottom of the adhesive layer 12 is bonded with a third release film 13. By providing the adhesive layer 12 and the third release film 13, the pipeline can be bonded and fixed, further improving the limiting effect of the pipeline.

[0025] During use, the butterfly needle is inserted into the surface of the injection seat, and then the first release film 10 is peeled off, and the first medical tape 2 and the protective film 1 are attached to the patient's skin surface. At this time, the protective film 1 and the wear-resistant layer 3 are located on the top of the butterfly needle. Then the third release film 13 and the second release film 11 are peeled off, and the bottom of the adhesive layer 12 is bonded to the connecting pipe of the butterfly needle. At this time, the pipe is located in the inner cavity of the tube groove 6, and then the second medical tape 4 is bonded to the patient's skin surface. Under the action of the rubber block 5 and the tube groove 6, the pipe can be limited and fixed to prevent it from displacement. Since there is a butterfly needle at the bottom of the protective film 1, the protective film 1 is in a raised state. When friction occurs between the protective film 1 and the clothing, the polyester film layer 7, the TPU film layer 8 and the nylon film layer 9 have excellent puncture resistance and wear resistance. Under the action of the polyester film layer 7, the TPU film layer 8 and the nylon film layer 9, the protective film 1 can be protected to prevent the surface of the protective film 1 from being worn.

[0026] In summary: the special film for the infusion port, through the cooperation of the second medical tape 4, the rubber block 5, the tube groove 6, the polyester film layer 7, the TPU film layer 8 and the nylon film layer 9, solves the problem that the existing film cannot limit and fix the tail end of the infusion needle during use, and the wear resistance of the surface of the film is poor and it is easy to wear.
