Description

Technical Field

[0001] This invention relates to the field of pipeline management technology, and in particular to a pipeline management device for an anti-tangle positive pressure ventilator. Background Technology

[0002] In the current technology, the tubing of positive pressure ventilators often faces many problems in clinical and home use due to the lack of effective management and fixation methods.

[0003] First, ventilator tubing is usually long and directly exposed, making it very easy for it to become tangled and twisted due to messy stacking when patients move, equipment is moved, or it is placed in a daily environment.

[0004] Tube entanglement not only restricts the patient's range of motion and affects their comfort, but may also lead to accidental dislodgement, kinking, or compression of the tube, thereby seriously affecting the stability of airflow delivery and the safety of treatment, and even causing treatment interruption.

[0005] Secondly, traditional tubing management methods mostly involve manual bundling or simple hanging, making it difficult to flexibly plan and adjust the support path of the tubing according to the actual usage scenarios such as patient position and equipment layout. This results in rigid tubing support paths that cannot adapt to diverse clinical and home care environments.

[0006] Furthermore, for longer pipelines, there is a lack of a mechanism to dynamically and orderly guide and control their extension and retraction, making it easy for the pipelines to get caught on surrounding objects or become tangled when the equipment is moved or stored, increasing the difficulty of management and time costs.

[0007] Therefore, there is a need for a conduit that can effectively prevent pipe tangling, flexibly adapt to different usage scenarios, and dynamically and orderly manage pipes. Summary of the Invention

[0019] Compared with the prior art, the beneficial effects of the present invention are: 1. The anti-tangling positive pressure ventilation machine tubing arrangement device provided by this invention achieves overall adjustment of the machine's position through a movable plate and support rods. It innovatively features an adjustable support structure on both sides of the support rods, consisting of a mounting plate, a T-shaped slide table that can slide along a first sliding groove, and a first support plate, a second support plate, and a third support plate connected in sequence. The left and right side tubing are respectively arranged inside these support plates. The angle and relative position between the support plates can be flexibly adjusted according to the actual routing requirements of the tubing, creating a smooth and orderly support path for the tubing. Combined with the cooperation between the tubing and the inner surfaces of the support plates, it fundamentally solves the problem of messy tangling caused by haphazard placement of tubing, ensuring smooth operation of the positive pressure ventilation machine tubing and treatment safety.

[0020] 2. The device of this invention uses a T-shaped slide table to slide within the mounting plate groove, thereby adjusting the horizontal and vertical positions of the entire adjustable support structure. This greatly improves the device's adaptability to pipelines of different lengths and spatial layouts. Simultaneously, the rotating connection structure between the support plates allows the device to be folded and stowed when not in use, significantly reducing space occupation and facilitating flexible placement, carrying, and storage in wards, treatment rooms, or home environments. This effectively solves the problems of poor flexibility and difficulty in adapting to diverse usage scenarios inherent in traditional pipeline management methods.

[0021] 3. The present invention provides a conveyor belt system with a limiting slide and a first convex groove on the inner side of the support structure. The conveyor belt is driven by a drive gear and a toothed shaft, which can pull the pipeline to move smoothly and orderly along a preset path. This design provides a reliable mechanism for the dynamic management of long pipelines, solves the problem of lack of active and orderly guidance for pipelines in the prior art, avoids the pipeline from hooking with external objects or getting tangled when the equipment is moved or adjusted, and improves the efficiency and stability of pipeline management.

[0022] 4. This invention achieves stable fixation and precise positioning of the first and second pipelines by setting precise clamping and limiting components such as an installation tube, a clamping plate, a first clamping slide, a second clamping slide, a first arc-shaped limiting buckle, and an L-shaped clamping buckle on the support plate. Through the coordinated work of the components, the adjustable support structure, and the conveyor belt system, it ensures that the pipelines are subjected to uniform force and accurate positioning throughout the entire process of arrangement, movement, and fixation. This further avoids the risk of pipeline damage and entanglement caused by excessive local pulling or positional displacement, and comprehensively improves the reliability, durability, and overall safety of positive pressure ventilation therapy.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1 to 13 The present invention provides a technical solution: A positive pressure ventilator piping straightening device for preventing tangling includes a movable plate 1. Movable wheels are rotatably mounted at the corners of the lower end face of the movable plate 1 for adjusting its position. A support rod 2 is fixedly mounted on the upper end face of the movable plate 1, and a working machine 7 is fixedly mounted on the top of the support rod 2. Figure 2 As shown.

[0028] Therefore, during operation, the moving plate 1 can adjust the position of the support rod 2 by means of the moving wheels, and then the support rod 2 moves the position of the working machine 7.

[0029] Mounting plates 201 are fixedly installed on both the left and right sides of the support rod 2. Symmetrical first sliding grooves 202 are formed inside both sides of the mounting plates 201. T-shaped sliding tables 203 are slidably installed inside each of the first sliding grooves 202. One end of the T-shaped sliding table 203 extends to the outside of the first sliding groove 202, and a first U-shaped plate 204 is fixedly installed on its outer side. Figure 3 and Figure 4 As shown.

[0030] A servo motor 205 is fixedly installed inside the T-shaped slide 203, and symmetrical support plates 207 are fixedly installed inside the first U-shaped plate 204. Drive gears 208 are rotatably mounted on the outer sides of the support plates 207, with a fixed connection between the two drive gears 208. A chain 206 is rotatably mounted on the circumferential surface of the central rotating shaft and the circumferential surface of the servo motor 205. Furthermore, a first toothed shaft 209 is rotatably mounted on the inner edge of the first U-shaped plate 204, and the first toothed shaft 209 and the drive gears 208 are meshed and rotate in mutual rotation. Figure 4 As shown.

[0031] Therefore, during use, when the servo motor 205 is started, its output shaft drives the two front and rear drive gears 208 to rotate synchronously through the chain 206. The drive gears 208 mesh with the first toothed shaft 209, thereby driving the first toothed shaft 209 to rotate at the edge of the first U-shaped plate 204.

[0032] By controlling the forward and reverse rotation and speed of the servo motor 205, the rotation angle and speed of the first toothed shaft 209 are adjusted, allowing the pipeline to be installed orderly on the conveyor belt 5. Combined with other structures, the pipeline is limited and fixed, effectively preventing entanglement caused by messy stacking and ensuring smooth operation of the positive pressure ventilation system. Simultaneously, the T-shaped slide 203 can slide up and down along the first slide groove 202, driving the first U-shaped plate 204 and related components to adjust their horizontal and vertical positions, further adapting to pipeline requirements of different lengths and layouts, and improving the flexibility and practicality of the device.

[0033] Secondly, a first support plate 3 is rotatably mounted inside the end of the first U-shaped plate 204 away from the T-shaped slide table 203; a first rotating plate 301 is rotatably mounted on the outer side of the end of the first support plate 3 away from the first U-shaped plate 204; a first adjusting plate 302 is rotatably mounted on the inner side of the end of the first rotating plate 301 away from the first support plate 3; and a second rotating plate 303 is rotatably mounted on the outer side of the end of the first adjusting plate 302 away from the first rotating plate 301. Figure 8 As shown.

[0034] A second support plate 304 is rotatably mounted on the inner side of the end of the second rotating plate 303 away from the first adjusting plate 302. A third rotating plate 305 is rotatably mounted on the outer side of the end of the second support plate 304 away from the second rotating plate 303. A second adjusting plate 306 is rotatably mounted on the inner side of the end of the third rotating plate 305 away from the second support plate 304. A fourth rotating plate 307 is rotatably mounted on the outer side of the end of the second adjusting plate 306 away from the third rotating plate 305. A third support plate 308 is rotatably mounted on the inner side of the end of the fourth rotating plate 307 away from the second adjusting plate 306. A second U-shaped plate 309 is rotatably mounted on the outer side of the end of the third support plate 308 away from the fourth rotating plate 307. A second toothed shaft 310 is rotatably mounted inside the second U-shaped plate 309. Figure 7 As shown.

[0035] Therefore, during the operation, the operator can flexibly adjust the angle between the first support plate 3, the second support plate 304 and the third support plate 308 by rotating the first rotating plate 301, the third rotating plate 305 and other components according to the actual route requirements of the pipeline. At the same time, the operator can use the extension and retraction characteristics of the first adjusting plate 302 and the second adjusting plate 306 to adapt to the changes in the length of the pipeline.

[0036] In summary, the aforementioned structure allows the first support plate 3, the second support plate 304, and the third support plate 308 to rotate and fold, thus enabling flexible adjustment of the tubing support path and effectively preventing tangling caused by excessive tubing length or disordered placement. When storage is required, the support plates can be folded and stowed, significantly reducing space occupation and facilitating daily carrying and storage. In actual use, medical personnel or users can adjust the angles of the rotating and adjusting plates according to the actual routing, length, and usage scenario of the positive pressure ventilation system tubing, ensuring the tubing remains in a smooth and orderly state. This reduces the impact of tubing twisting on airflow efficiency and prevents tubing wear or accidental pulling due to tangling, improving the stability and safety of positive pressure ventilation therapy. Furthermore, the rotating connections are made of highly wear-resistant engineering plastic material, combined with a smooth rotating shaft structure, ensuring stable rotational performance even with frequent adjustments over a long period, further enhancing the device's practicality and durability, meeting diverse needs for clinical and home use. Additionally, the rotating connections do not compress the tubing when folded. Then, conveyor belts 5 are rotatably mounted on both ends of the first toothed shaft 209 and the second toothed shaft 310. Thus, during use, the drive gear 208 drives the first toothed shaft 209 to rotate, the first toothed shaft 209 rotates with the conveyor belt 5, and the conveyor belt 5 rotates with the second toothed shaft 310, thereby enabling the first pipeline 506 and the second pipeline 603 to move in subsequent operations.

[0037] Secondly, limiting slides 501 are fixedly installed on the outer side of the conveyor belt 5, and the limiting slides 501 are slidably installed inside the first convex groove 4. The first convex groove 4 is located at the upper and lower edges of the inner sides of the first U-shaped plate 204, the first support plate 3, the first rotating plate 301, the second rotating plate 303, the second support plate 304, the third rotating plate 305, the fourth rotating plate 307, the third support plate 308, and the second U-shaped plate 309. Figure 8 As shown.

[0038] Therefore, during use, the conveyor belt 5 is restricted by the limiting slide 501, preventing vibration and loosening after folding. Furthermore, during operation, the conveyor belt 5 can smoothly pull the first pipeline 506 and the second pipeline 603 along the preset path. The precise cooperation between the limiting slide 501 and the first convex groove 4 not only restricts the lateral displacement of the conveyor belt 5, but also guides it to maintain a regular arrangement during the folding or unfolding of the device, effectively preventing the pipeline from getting tangled or twisted due to positional deviation.

[0039] Meanwhile, this structural design ensures that the pipeline is subjected to uniform force during movement, avoiding damage caused by excessive local stretching, and further improving the reliability and service life of the device. In addition, when the device is folded, the limiting slide 501 will slide synchronously along the first convex slide groove 4 to ensure that the conveyor belt 5 and the pipeline it carries are always in an orderly state and there will be no mutual squeezing or jamming, thereby ensuring the efficiency and stability of pipeline arrangement.

[0040] Then, an installation tube 502 is fixedly installed on the right edge of the two left conveyor belts 5. The inside of the installation tube 502 is provided with an annular groove 503. Springs 504 are evenly fixedly installed in an annular array inside the annular groove 503. Four springs 504 are arranged in a group, and an arc-shaped clamping plate 505 is fixedly installed at one end inside. There is a certain gap between each clamping plate 505. Thus, after one end of the first pipe 506 slides into the inside of the installation tube 502, the first pipe 506 is clamped by the clamping plate 505 under the action of the spring 504.

[0041] It should be noted that the left side of the clamping plate 505 has a sloping structure, which facilitates the sliding of the first pipe 506 and avoids the clamping plate 505 obstructing the first pipe 506.

[0042] Secondly, second convex grooves 401 are provided on the upper surfaces of the first support plate 3, the second support plate 304, the third support plate 308, and the second U-shaped plate 309. First clamping slides 402 are slidably installed inside each of the second convex grooves 401, and first arc-shaped limiting buckles 403 are rotatably installed inside each first clamping slide 402. Figure 12 As shown.

[0043] It should be noted that the first arc-shaped limiting buckle 403 can rotate under the action of the internal driving device. Also, after the first support plate 3, the second support plate 304, and the third support plate 308 are folded, the first arc-shaped limiting buckle 403 will not obstruct or interfere with the subsequent pipeline folding operation.

[0044] Secondly, a hollow column 602 is fixedly installed on the upper left side of the right conveyor belt 5. The internal structure of the hollow column 602 is the same as that of the mounting pipe 502, and the working effect is the same. Therefore, a second pipe 603 is slidably installed inside the hollow column 602, such as... Figure 13 As shown.

[0045] Then, a second clamping slide 6 is slidably installed inside the second convex slide groove 401 on the right side. An L-shaped clamping buckle 601 is rotatably installed inside the upper end of the second clamping slide 6. The L-shaped clamping buckle 601 can rotate under the action of the internal driving structure, thereby clamping and limiting the second pipeline 603.

[0046] Therefore, under the combined effect of the above-mentioned structure, it is possible to achieve comprehensive and dynamic management and limiting of positive pressure ventilator tubing. Whether it is a complex scenario with multiple tubing running in parallel in clinical departments or a simple need in home care, the device can ensure that the tubing always remains in a smooth and tangle-free state by flexibly adjusting the support path and precisely controlling the speed and position of tubing movement.

[0047] Medical staff only need to adjust the angle of each rotating plate according to actual needs and control the operation of the conveyor belt 5 through the servo motor 205 to quickly complete the arrangement and fixation of the pipeline, which greatly reduces the time cost of pipeline management.

[0048] Meanwhile, the device adopts a modular design for each component, which facilitates daily cleaning and maintenance. When a component is damaged, it can be replaced individually, reducing the cost of use.

[0049] In addition, the device is made of lightweight materials and features convenient mobility with casters, making it easy to adapt to different environments. Whether in wards, treatment rooms or home bedrooms, it can be flexibly placed and used, truly achieving a perfect combination of practicality and convenience, and providing reliable pipeline support for the smooth implementation of positive pressure ventilation therapy.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; 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 or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
