Abstract
Description
Technical Field
[0001] This invention relates to the field of medical supplies technology, specifically to a detachable bedside drainage tube fixing device with a sliding rail. Background Technology
[0002] Following surgery, drainage tubes are often required, such as various wound drainage tubes (e.g., pelvic drainage tubes, renal fossa drainage tubes), and stoma tubes (e.g., nephrostomy tubes, cystostomy tubes). These drainage tubes typically need to be left in place for 2-10 days, sometimes longer, up to several months. Ensuring the smooth and secure placement of these drainage tubes post-surgery is often crucial for surgical success. Dislodgement of the drainage tubes can have serious consequences, ranging from the need for re-placement and increased patient suffering to, in severe cases, endangering the patient's life.
[0003] Currently, in clinical practice, drainage tubes are usually simply secured to the bedside with pins or ties. However, the position of the pins is not calculated or measured, and the pins may come loose, potentially injuring the patient or caregivers. Furthermore, there is no clear area for the patient to turn over, which can easily cause the catheter to be pulled or dislodged, leading to wound bleeding, accidental tube removal, and other complications that could delay treatment. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a detachable bedside drainage tube fixation device with a sliding rail. This device overcomes the deficiencies of existing technologies, is reasonably designed, and can effectively avoid the problem of needlestick injuries caused by using sharp instruments for fixation. It also allows for adaptive adjustment of the fixation position of the drainage tube, thereby effectively avoiding the problem of accidental tube removal or bleeding caused by traction on the drainage tube.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A detachable bedside drainage tube fixing device with a slide rail includes a linear slide rail and a triangular sliding frame. The linear slide rail is fixedly installed on the side of the bed. The triangular sliding frame has a triangular sliding groove. A fixed bearing is installed at one corner of the triangular sliding frame. A rotating shaft is installed in the middle of the fixed bearing. The end of the rotating shaft passes through the triangular sliding frame and is equipped with a sliding component. The sliding component is movably installed in the linear slide rail.
[0007] A sliding bearing is slidably connected inside the triangular sliding groove. A positioning ball is installed inside the sliding bearing. A bowl-shaped notch is opened on the surface of the positioning ball. The drainage tube first enters the sliding bearing from the inner side of the triangular sliding frame, passes through the bowl-shaped notch, circles around the bowl-shaped notch, and then exits from the inner side of the triangular sliding frame and is implanted into the human body.
[0008] Preferably, the sliding element is a pulley, and the linear slide rail has a guide groove, with the pulley slidably connected within the guide groove.
[0009] Preferably, the slider is an inverted L-shaped slider, and a limiting groove is provided below the inner wall of the linear slide rail, and the vertical section of the inverted L-shaped slider is slidably connected in the limiting groove.
[0010] Preferably, a gap is reserved between the linear slide rail and the triangular sliding frame to allow the drainage tube to pass through.
[0011] Preferably, multiple sliding bearings are provided, and each sliding bearing is slidably connected in a triangular sliding groove.
[0012] Preferably, the triangular sliding groove has a circular groove at one end near the fixed bearing, and the inner diameter of the circular groove is larger than the outer diameter of the sliding bearing.
[0013] This invention provides a detachable bedside drainage tube fixation device with a sliding rail. It offers the following advantages: by wrapping the drainage tube around the surface of the positioning ball along a bowl-shaped notch, the position of the drainage tube is fixed, thus avoiding needlestick injuries caused by sharp objects used in existing technologies; by controlling the sliding of the sliding member within the linear rail, the position of the entire triangular sliding frame along the length of the bed can be adjusted; furthermore, the sliding connection of the sliding bearing within the triangular sliding groove allows for adjustment of the position of the entire sliding bearing on the triangular sliding frame; and since the entire triangular sliding frame can rotate around its own axis, when the patient turns over or other movements causing traction, the triangular sliding frame itself can rotate, and the sliding bearing can also adaptively slide within the triangular sliding groove, allowing for adaptive adjustment of the drainage tube's fixation position. This effectively avoids accidental tube removal or bleeding due to traction on the drainage tube. It ensures the safety of drainage tubes in clinical care and reduces the incidence of adverse events caused by drainage tube dislodgement. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0025] Example 1, as Figure 1-7 As shown, a detachable bedside drainage tube fixing device with slide rail includes a linear slide rail 1 and a triangular sliding frame 2. The linear slide rail 1 is fixedly installed on the side of the bed. The triangular sliding frame 2 has a triangular sliding groove 3. A fixed bearing 4 is installed at one corner of the triangular sliding frame 2. A rotating shaft 5 is installed in the middle of the fixed bearing 4. The end of the rotating shaft 5 passes through the triangular sliding frame 2 and is equipped with a sliding member 6. The sliding member 6 is movably installed in the linear slide rail 1.
[0026] A sliding bearing 7 is slidably connected inside the triangular sliding groove 3. A positioning ball 8 is installed inside the sliding bearing 7. A bowl-shaped notch 9 is opened on the surface of the positioning ball 8. The drainage tube first enters the sliding bearing 7 from the inner side of the triangular sliding frame 2, and then passes through the bowl-shaped notch 9. After circling around the bowl-shaped notch 9, it passes out from the inner side of the triangular sliding frame 2 and is implanted into the human body.
[0027] Working principle:
[0028] In use, the drainage bag 13 is first fixed in a suitable position next to the bed. The drainage tube 14 can be inserted into the sliding bearing 7 from the inner side between the triangular sliding frame 2 and the linear slide rail 1, and then wrapped around the surface of the positioning ball 8 along the bowl-shaped notch 9. Finally, it is passed out from the inner side between the triangular sliding frame 2 and the linear slide rail 1 to limit the position of the drainage tube 14, thereby avoiding the needle stick injury caused by the use of sharp objects for fixation in the prior art. The drainage tube is then implanted into the lesion site such as human fluid accumulation, abscess, or necrosis. During use, the position of the entire triangular sliding frame 2 along the length of the bed can be adjusted by controlling the sliding of the sliding part 6 in the linear slide rail 1.
[0029] Furthermore, through the sliding connection of the sliding bearing 7 within the triangular sliding groove 3, the position of the entire sliding bearing 7 on the triangular sliding frame 2 can be adjusted. Since the sliding element 6 is mounted on the rotating shaft 5, and the rotating shaft 5 is rotatably connected to the triangular sliding frame 2 via the fixed bearing 4, the entire triangular sliding frame 2 can also rotate around the rotating shaft 5. Therefore, when the patient performs actions such as turning over and causing traction, such as... Figure 5-6 As shown, the triangular sliding frame 2 can rotate, and the sliding bearing 7 can also be adaptively adjusted within the triangular sliding groove 3. This allows the sliding bearing 7 to be closer to the patient, enabling adaptive adjustments to the fixing position of the drainage tube. This effectively avoids traction on the drainage tube, preventing accidental dislodgement or bleeding. It ensures the safety of the drainage tube in clinical care and reduces the incidence of adverse events caused by drainage tube dislodgement.
[0030] Specifically, when the patient is lying flat, there is no traction on the drainage tube. At this time, the triangular sliding frame 2 will be in a position similar to... Figure 7 The image shows the natural hanging state; when the patient performs actions such as turning over, causing traction, it first moves the entire triangular sliding frame 2 along the linear slide rail 1 to the appropriate position; at the same time, it also moves the sliding bearing 7 to slide within the triangular sliding groove 3. After sliding to one corner of the triangular sliding groove 3, as shown... Figure 5 As shown, the pulling force will cause the triangular sliding frame 2 to rotate around the rotating axis 5, which in turn causes the angle of the sliding bearing 7 in the triangular sliding groove 3 to rotate upward, so that the sliding bearing 7 can be closer to the patient, so that the fixed position of the drainage tube can be closer to the patient.
[0031] In Example 2, as a further preferred embodiment of Example 1, the sliding member 6 is a pulley, and a guide groove is provided in the linear slide rail 1, with the pulley slidably connected within the guide groove. Through the sliding connection of the pulley within the guide groove of the linear slide rail 1, the stability of the entire triangular sliding frame 2 when sliding along the linear slide rail 1 can be effectively ensured.
[0032] In Example 3, as a further preferred embodiment of Example 1, the slider 6 is an inverted L-shaped slider, and a limiting groove is provided on the lower inner wall of the linear slide rail 1. The vertical section of the inverted L-shaped slider is slidably connected within the limiting groove. Therefore, during use, the triangular sliding frame 2 can be hooked onto the linear slide rail 1 via the inverted L-shaped slider, and the limiting groove on the lower inner wall of the linear slide rail 1 can be used to limit the movement of the slider 6. After use, the slider 6 can be directly removed from the linear slide rail 1 for disinfection and storage.
[0033] In Example 4, as a further preferred embodiment of Example 1, a gap is provided between the linear slide rail 1 and the triangular sliding frame 2 to allow the drainage tube to pass through. In this embodiment, the length of the portion of the rotating shaft 5 extending beyond the triangular sliding frame 2 can be increased, allowing the triangular sliding frame 2 to move away from the linear slide rail 1. This provides sufficient space for the drainage tube to move as it enters and exits from the inner side between the triangular sliding frame 2 and the linear slide rail 1, thus avoiding the problem of the drainage tube being squeezed by the triangular sliding frame 2 and the linear slide rail 1.
[0034] In Example 5, as a further preferred embodiment of Example 1, multiple sliding bearings 7 are provided, each sliding bearing 7 being slidably connected within a triangular sliding groove 3, and each sliding bearing 7 having a positioning ball 8 installed within it. Thus, when multiple drainage tubes are needed, each drainage tube can be respectively wound around the corresponding bowl-shaped notch 9 on the surface of the positioning ball 8 within each sliding bearing 7, thereby defining the position of each drainage tube. Furthermore, by arranging the sliding bearings 7 side-by-side within the triangular sliding groove 3, the drainage tubes can be neatly arranged side-by-side, effectively avoiding the problem of mutual entanglement between the drainage tubes.
[0035] In Example 6, as a further preferred embodiment of Example 5, a circular slot 11 is formed near the lower end of the fixed bearing 4 in the triangular sliding slot 3. The inner diameter of the circular slot 11 is larger than the outer diameter of the sliding bearing 7. This allows the sliding bearing 7 to be directly removed from the circular slot 11. Therefore, the same number of sliding bearings 7 can be selected according to the required number of drainage tubes, and the sliding bearing 7 can be directly inserted into the triangular sliding slot 3 from the circular slot 11 and then slid into the triangular sliding slot 3.
[0036] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
