Description

Technical Field

[0001] The utility model relates to the technical field of indwelling needle film, in particular to a disposable tension-reducing transparent film. Background Art

[0002] An indwelling needle is a medical device that is inserted into the patient's body for long-term retention. The use of an indwelling needle can reduce the pain caused by repeated venous punctures and the patient's fear of injections. In order to improve the placement stability of the indwelling needle, it is necessary to use a film to stick and fix the indwelling needle. However, the following disadvantages exist in the process of fixing the indwelling needle with an existing transparent film: 1. The film of the intravenous indwelling needle is prone to curling and looseness during the fixation process; 2. The stop clamp causes blood reflux in the catheter due to its distance from the puncture point when clamped. Utility Model Content

[0022] See also Figure 1-4 , the utility model provides a technical solution:

[0023] A disposable tension-reducing transparent film comprises a release paper 4, the left end of which is fixedly connected to a hand-peeling paper 6, the upper end of which is coated with a waterproof layer 5, the upper end surface of which is provided with a skin-friendly layer 2, the upper end surface of which is coated with an adhesive glue 3, the release paper 4 is adhered to an indwelling needle fixing structure 1 by the adhesive glue 3, and the front end left portion of the indwelling needle fixing structure 1 is fixedly connected to a fixed flow-stopping clip structure 7.

[0024] In this embodiment, the indwelling needle fixing structure 1 includes a lower film 11, the upper end surface of the lower film 11 is provided with a breathable layer 12, the middle part of the upper end of the lower film 11 is inserted and fixedly connected with an adhesive component 13, the adhesive component 13 includes a transparent film 131, the upper left part of the transparent film 131 is provided with a tension relief opening 133 with a front end passing through, the upper end of the transparent film 131 is pasted with a marking paper 132, the lower end of the transparent film 131 is fixedly connected with a sterile gauze 134, the transparent film 131 is fixedly connected to the middle part of the upper end of the lower film 11, and the lower end of the sterile gauze 134 is tightly connected to the upper end surface of the peeling paper 4. Sticking; by providing an indwelling needle fixing structure 1, a forty-five-degree tension relief opening 133 is obliquely opened at the front of the upper end of the transparent film 131, and the lower sticking film 11 can be pasted to the puncture point of the indwelling needle through the adhesive glue 3, so that the transparent film 131 can be tightly attached to the puncture center point of the indwelling needle, and the indwelling needle hose passes through the tension relief opening 133. The transparent film 131 can be smoothed by hand, and the air in the transparent film 131 can be discharged through the tension relief opening 133, so that curling will not occur during the process of sticking the film on the indwelling needle, and the indwelling needle can be tightly fixed on the arm.

[0025] In this embodiment, the fixed stop-flow clip structure 7 includes a skin-friendly tape 71, the lower end of the skin-friendly tape 71 is provided with an arc-shaped opening 72, the lower end of the skin-friendly tape 71 is provided with an adhesive layer 73, the skin-friendly tape 71 is fixedly connected to the left front end of the lower film 11, and the skin-friendly tape 71 is located on the left side of the tension relief opening 133; by setting the fixed stop-flow clip structure 7, the skin-friendly tape 71 is fixed to the left front end of the lower film 11, and the skin-friendly tape 71 is located on the left side of the tension relief opening 133. When the skin-friendly tape 71 is used in conjunction with the adhesive layer 73, the skin-friendly tape 71 can adhere and fix the stop-flow clip on the indwelling needle to the skin, and close to the tension relief opening 133, so as to avoid the occurrence of catheter blood reflux due to the distance from the puncture point when the stop-flow clip is clamped.

[0026] It should be noted that the utility model is a disposable tension-reducing transparent film. When using the film, the peeling paper 4 can be torn off from the adhesive glue 3 by holding the edge of the peeling paper 6, so that the marking paper 132 marked on the transparent film 131 is aligned with the needle eye position of the indwelling needle, and then the lower film 11 is adhered to the skin through the adhesive glue 3, so that the transparent film 131 is attached to the puncture site of the indwelling needle. At this time, the person can pinch and smooth the transparent film 131 attached to the indwelling needle, so that the gas in the transparent film 131 can be discharged through the tension-reducing opening 133, so that the indwelling needle can be tightly fixed to the skin, and the tension-reducing opening can be opened. The opening 133 can prevent the indwelling needle from curling and becoming loose when the film is applied during the fixing process. In addition, a fixed stop-flow clip structure 7 is fixed to the left part of the front end of the lower film 11. The fixed stop-flow clip structure 7 is provided with a skin-friendly tape 71, an arc-shaped opening 72 and an adhesive layer 73. The skin-friendly tape 71 is located on the left side of the tension relief opening 133. After the indwelling needle hose passes through the tension relief opening 133, one end of the stop-flow clip outside the indwelling needle can be fixed to the skin with the cooperation of the skin-friendly tape 71, which can prevent the blood in the catheter from reflux due to the stop-flow clip being too far away from the puncture point when clamped, thereby increasing the safety of the indwelling needle.
