Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, specifically to a disposable sterile protective sleeve for the tail wire of a radiofrequency ablation electrode catheter and its connection structure. Background Technology

[0002] In my country, over 1.6 million cardiac interventional procedures are performed annually, half of which are cardiac electrophysiological diagnostic / ablation procedures. Cardiac interventional nursing care is a prerequisite for ensuring the safety and effectiveness of cardiac interventional treatments and a key to reducing the incidence of various complications; its quality is closely related to patient safety.

[0003] Each electrophysiological diagnostic / ablation procedure requires the connection of 1-3 electrode catheters and electrode tail wires. The tail wire interface is connected to the external electrophysiological system via a cable. The electrode tail wire is not disposable and is a contaminated part of the equipment used during the procedure. Currently, the disposable plastic sterile protective sleeves used are not dedicated to the electrode catheters and tail wires. Two people are required to work together to put on the protective sleeves. Because the cables are long, they need to be put on section by section, which is cumbersome and time-consuming. Furthermore, the loose and tight ties do not easily secure the sterile ends, affecting the operator's catheter manipulation. All of these aspects have weak quality control points, posing a risk of nosocomial infection. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the above-mentioned technologies by providing a disposable sterile protective sleeve for the tail wire of a radiofrequency ablation electrode catheter and its connection structure. This sleeve can properly fix the sterile end, solve the problem of cumbersome and time-consuming connection of the tail wire of the electrode catheter during cardiac electrophysiological diagnosis / ablation, and reduce the risk of nosocomial infection.

[0005] To achieve the above objectives, the disposable sterile protective sleeve for the tail wire of the radiofrequency ablation electrode catheter involved in this utility model includes a ring-shaped stacked sterile protective film. One end of the sterile protective film is provided with a ring-shaped fixing sleeve, and the other end is provided with a handle.

[0006] Preferably, an inwardly rolled adhesive layer is adhered to the inner wall of the fixing sleeve.

[0007] Preferably, the fixing sleeve is provided with a secondary fixing adhesive strip.

[0008] Preferably, one end of the handle strip is fixed to the end of the sterile protective film, and the other end extends outward.

[0009] A connection structure for a disposable sterile protective sleeve for the tail wire of the radiofrequency ablation electrode catheter, wherein the sterile protective film is sleeved on the tail wire and the fixing sleeve is fixedly connected to the end of the electrode catheter handle.

[0010] Preferably, an inwardly rolled adhesive layer is adhered to the inner wall of the fixing sleeve, and the fixing sleeve is adhered and fixed to the end of the electrode conduit handle by the inwardly rolled adhesive layer.

[0011] Preferably, the fixing sleeve is provided with a secondary fixing adhesive strip, and the fixing sleeve is fixed to the end of the electrode conduit handle by the secondary fixing adhesive strip.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] 1. It can properly fix the sterile end, avoiding and eliminating the disadvantage of the protective sleeve currently used in clinical practice that requires ties, and solving the problem of cumbersome and time-consuming connection of electrode catheter tail wires in cardiac electrophysiological diagnosis / ablation procedures;

[0014] 2. By pulling the handle strip, the sterile protective film can be placed on the tail line, which will not cause contamination and reduces the risk of nosocomial infection;

[0015] 3. The grabbing and docking operations are simple and quick, saving time and effort, and easy to replace. Moreover, it has a wide range of applications and strong practicality. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, a disposable sterile protective sleeve for the tail wire of a radiofrequency ablation electrode catheter includes a ring-shaped stacked sterile protective film 1, one end of which is provided with a ring-shaped fixing sleeve 2, and the other end is provided with a handle strip 3.

[0023] In this embodiment, the sterile protective film 1 is placed on the tail wire, and the fixing sleeve 2 is fixedly connected to the end of the electrode catheter handle.

[0024] If the inner wall of the fixing sleeve 2 is covered with an inwardly rolled adhesive layer 4, the fixing sleeve 2 is fixed to the end of the electrode conduit handle by the inwardly rolled adhesive layer 4. If the fixing sleeve 2 is provided with a secondary fixing adhesive strip 5, the fixing sleeve 2 is fixed to the end of the electrode conduit handle by the secondary fixing adhesive strip 5.

[0025] The fixing sleeve 2 can also be fixed to the end of the electrode conduit handle by means of the inner rolled adhesive layer 4, and at the same time by means of the secondary fixing adhesive strip 5, so that the structure is more stable.

[0026] Specifically, when using the product, the operator opens the packaging, picks up the sterile protective sleeve, and places the end with the handle strip 3 towards themselves. The electrode catheter tail wire is placed inside the sterile protective film 1. At this time, the fixing sleeve 2 is pinched tightly, and the fixing sleeve 2 is fixedly connected to the end of the electrode catheter handle by the inner roll adhesive layer 4. Then, the handle strip 3 is pulled to unfold the sterile protective film 1 to the position where the cable needs to be protected.

[0027] In addition, when fixing the fixing sleeve 2, it can also be reinforced by using the secondary fixing adhesive strip 5.

[0028] In this embodiment, the inner roll adhesive layer 4 adopts a medical-grade adhesive design, and the sterile protective film 1 is made of polyethylene film material. Various models and specifications can be designed according to needs. The commonly used model is 5cm in diameter and 150cm in length, which is suitable for most electrode catheters and tail wires.

[0029] This invention relates to a disposable sterile protective sleeve and its connection structure for the tail wire of a radiofrequency ablation electrode catheter. It can properly fix the sterile end, avoiding and eliminating the disadvantage of the need for ties required for the protective sleeves currently used in clinical practice. This solves the problem of cumbersome and time-consuming connection of the electrode catheter tail wire in cardiac electrophysiological diagnosis / ablation procedures. By pulling the handle strip 3, the sterile protective film 1 can be put on the tail wire without causing contamination, reducing the risk of nosocomial infection. The grasping and docking operations are simple and quick, saving time and effort, and are easy to replace. Moreover, it has wide applications and strong practicality.
