Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a CVC tube external fixation component. Background Technology

[0002] CVC, or central venous catheter, is a commonly used interventional device in medicine. It is mainly used to provide patients with long-term or short-term venous access to facilitate various medical procedures such as infusion, blood transfusion, hemodialysis, central venous pressure monitoring, and drug administration. It is usually inserted into a central vein such as the superior vena cava or inferior vena cava to ensure that drugs or fluids can be distributed quickly and accurately throughout the body.

[0003] The adhesive tape commonly used to fix CVC tubes is prone to falling off due to factors such as patient activity, sweat, or skin oils, leading to instability in the CVC tube's position and potentially causing safety risks. At the same time, transparent adhesive dressings are prone to curling and falling off at the edges after prolonged use. This not only affects the fixation's firmness but may also irritate the patient's skin due to the curling edges, causing discomfort. Furthermore, traditional adhesive fixation methods can easily trigger skin allergic reactions such as redness, swelling, and itching after prolonged contact with the skin, causing additional pain to the patient.

[0024] Reference Figures 1 to 6 In this embodiment of the present invention, an external fixation assembly for a CVC tube includes: a fixation assembly 1 and a fixation assembly 2. The fixation assembly 1 is applied to the CVC tube wound, and the fixation assembly 2 is used to fix the CVC tube in the neck. The CVC tube is snapped into the lower support plate 3. The support plate 3 is made of silicone material. The support plate 3 not only provides necessary support for the CVC tube, but also has a groove in the middle to facilitate the fixation of the CVC tube body, and also ensures its stability during use. The silicone plate 4 fixedly installed on the side of the support plate 3, with its soft and conforming characteristics, fits tightly to the CVC tube wound, effectively preventing the tube from sliding and falling off, and also providing additional comfort for the patient. The reflective strip 5 fixedly attached above the silicone plate 4 can clearly show the position of the CVC tube under light, which greatly facilitates the operation of medical staff.

[0025] The breathable dressing layer 6 below the silicone pad 4 ensures that the skin can maintain good breathability even after being fixed for a long time, avoiding discomfort caused by prolonged pressure on the skin. In addition, the pipe fixing component 7 set in the middle of the upper part of the silicone pad 4 provides additional protection for the fixation of the CVC tube, ensuring its stability under various conditions.

[0026] The support rod 71 serves as a fixing point, securely positioned above the silicone plate 4, providing support for the spring 72 below. The elastic design of the spring 72 allows the clamping plate 73 to automatically adjust the clamping force according to the size of the CVC tube, ensuring that CVC tubes of different sizes can be securely fixed. The pull rod 74, fixed in the middle of the upper part of the clamping plate 73, provides convenience for the user. When it is necessary to adjust the CVC tube, pulling the pull rod 74 will release the clamping plate 73, thereby easily completing the replacement or adjustment of the pipeline, improving work efficiency, and ensuring the simplicity and safety of operation.

[0027] At the other end of the CVC tube, the fixing component 2 is tightly connected to the connecting plate 9 via a fixed sleeve movable buckle 8. The connecting plate 9, as the core of the binding system, is fixedly connected to a breathable elastic bandage 10 on one side and a breathable elastic bandage 11 on the other side. The design of these two bandages not only ensures the stable binding of the CVC tube at the patient's neck, but also provides good comfort for the patient through the selection of breathable materials. The locking hole 13 above the breathable elastic bandage 10 and the locking bar 15 below the breathable elastic bandage 11 combine to achieve quick and firm binding. At the same time, the arc-shaped patch 12 below the connecting plate 9 ensures that the binding system can closely fit the curve of the patient's neck, further improving the stability of the fixation and the patient's comfort. The sanitary pad 14 below the breathable elastic bandage 10 provides the patient with additional skin protection and reduces the discomfort that may be caused by prolonged binding.

[0028] The working principle of this utility model is as follows:

[0029] First, the tray 3 is placed on the patient's skin. Because the tray 3 is made of silicone and has a groove in the middle, CVC tubes of different sizes can be stably placed in the groove on the top of the tray 3. The silicone adhesive plates 4 on both sides of the tray 3 are tightly attached to the CVC tube wound through the breathable adhesive layer 6 to ensure fixation while keeping the skin breathable. The reflective strip 5 set on the top of the silicone adhesive plate 4 can provide visibility under light, making it easy for medical staff to quickly identify the position of the CVC tube.

[0030] At the center above the silicone plate 4, the pipe fixing assembly 7 further stabilizes the CVC tube. Specifically, the spring 72 fixed below the support rod 71 can provide appropriate elasticity according to the size of the CVC tube, so that the clamping plate 73 tightly clamps the CVC tube. When it is necessary to adjust or replace the CVC tube, the clamping plate 73 can be temporarily loosened by pulling the pull rod 74 for easy operation.

[0031] In addition, the other end of the CVC tube is fixedly connected to a fixing component 2, which includes a movable buckle 8. The movable buckle 8 fixes the CVC tube, and the connecting plate 9 below the movable buckle 8 is bound to the patient's neck by a breathable elastic band 10 and a breathable elastic band 11. The design of the breathable elastic band 10 and the breathable elastic band 11 not only ensures the stability of the fixation, but also takes into account the patient's comfort. The locking bar 15 on the breathable elastic band 11 can be locked into the locking hole 13 on the breathable elastic band 10 to achieve quick and firm binding. At the same time, the arc-shaped patch 12 below the connecting plate 9 ensures that the binding fits the curve of the patient's neck, increasing the stability of the fixation and the patient's comfort. The sanitary pad 14 below the breathable elastic band 10 provides additional skin protection and reduces the discomfort that may be caused by prolonged binding.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
