Description

Technical Field

[0001] The utility model relates to the technical field of a multi-balloon clamp and a batch of drug balloon coating equipment, and more particularly, to a multi-balloon clamp and a batch of drug balloon coating equipment. Background Art

[0002] In the current medical device manufacturing industry, the production and coating processes of drug-eluting balloons face a series of technical challenges that need to be addressed urgently. These problems not only affect production efficiency but may also have potential negative impacts on product quality.

[0003] First of all, the existing drug balloon coating equipment generally has the problem of low efficiency. Most equipment still uses a single balloon spraying method, which is particularly limited in large-scale production. Only one balloon can be processed at a time, which means that the entire production process becomes lengthy and time-consuming, which not only reduces the overall production efficiency, but also increases production costs. What is more worrying is that the existing technology generally relies on manual operation to tighten the balloon. This manual operation is not only time-consuming and labor-intensive, but also introduces uncertainty caused by human factors. The operator's skill level and fatigue level may affect the tension of the balloon, and thus affect the uniformity and quality of the coating. Long-term repetitive work may also cause occupational health problems for the operator. This manual dependence not only reduces production efficiency, but also increases labor costs and the difficulty of quality control.

[0004] Secondly, existing drug application equipment generally has problems with simple structure and poor adaptability. Most devices are designed with only balloons of fixed sizes in mind and lack the flexibility to adapt to balloons of different diameters. This structure severely limits the application range of the equipment. In actual production, the size of drug balloons may vary in response to different clinical needs. Fixed-structure equipment cannot meet such diverse production needs, which may result in the production line needing to frequently replace equipment or make complex adjustments, which not only increases production costs but may also extend the production cycle.

[0005] To address the above issues, some manufacturers have attempted to develop clamping devices that can adapt to balloons of different diameters. However, these improved devices still have obvious shortcomings. Although they can theoretically clamp balloons of different sizes, their structural designs are often too simple to provide a stable and reliable clamping effect. This instability may cause serious problems in the actual production process. When the balloon is subjected to external pressure, vibration or impact, these simple clamping devices are prone to loosening and may even cause the balloon to fall off completely, which will not only interrupt the production process, but may also cause product damage or contamination, seriously affecting product quality and production efficiency.

[0017] (3) Beneficial effects

[0018] Compared with the existing technology, the present invention provides a multi-balloon clamp and a batch drug balloon coating device, which has the following beneficial effects:

[0019] 1. The coating device realizes the function of simultaneous coating of multiple balloons through the ingenious combination of components such as the base, the lead screw and the movable seat. The motor drives the lead screw to rotate, driving the movable seat to move smoothly on the slide rail, ensuring the uniform stretching of the balloon. This design not only greatly improves production efficiency, but also ensures the consistency of the coating process. The coordination of the slide rail and the slider ensures the stability and accuracy of the movement of the movable seat, effectively avoiding jitter and deviation during the coating process. This automated coating method not only reduces manual operation, but also significantly improves the consistency of product quality.

[0020] 2. The clamping device realizes flexible clamping of the balloon through the precise coordination of the clamping sleeve, matching sleeve, movable block, sliding sleeve and guide sleeve. The movable block can automatically adjust the clamping position according to the diameter of the balloon through the sliding of the movable plate in the movable groove. The design of the push spring and the clamping plate ensures a soft and firm clamping of the balloon and avoids damage to the balloon. The coordination of the guide sleeve and the guide block further enhances the accuracy and stability of the clamping. This adjustable clamping mechanism not only adapts to balloons of different specifications, but also ensures the consistency and reliability of the clamping process.

[0021] 3. The design of the limiting mechanism further enhances the stability and reliability of the clamping device. Through the ingenious cooperation of the limiting frame, limiting sleeve, rotating plate, limiting plate, limiting groove, giving groove, spring, limiting rod and conical spring, the precise locking of the clamping position is achieved. The design of the rotating plate and the giving groove allows the operator to flexibly adjust the position of the limiting sleeve when needed, thereby contacting the limiting of the mating sleeve, and providing a stable lock during normal use. The cooperation of the limiting rod and the limiting groove ensures that the position of the mating sleeve is fixed, preventing loosening due to external vibration or impact during the application process. This multiple locking mechanism not only prevents the accidental loosening or falling off of the clamping part, but also ensures stability after long-term use. BRIEF DESCRIPTION OF THE DRAWINGS

Due to the rounded structural design at the end of the limit rod 17 and the edge of the limit groove 14, and the conical spring 18 only provides a weak reset force, the side wall of the limit groove 14 squeezes the side wall of the limit rod 17, so that one end of the limit rod 17 slides out of the limit groove 14, and at the same time, the other end of the limit rod 17 drives the conical spring 18 to stretch. At the same time, since the inner wall of the rotating sleeve and the outer side of the sliding sleeve 8 are movably connected by threads, and the longitudinal groove 23 limits the fixed rod 24, the sliding sleeve 8 will drive the fixed rod 24 to slide along the longitudinal groove 23, and then the fixed rod 24 drives the guide sleeve 9 to slide, and the guide sleeve 9 drives the movable block 7 to move through the guide block 26 and the guide groove 25, and then the movable The movable block 7 will drive the movable plate 22 to slide along the movable groove 21. Due to the inclined structural design of the movable groove 21 and the movable plate 22, the movable plate 22 will drive the movable block 7 to spread outward while sliding. At the same time, the movable block 7 will drive the push spring 19 and the clamping plate 20 set on the other side to move outward, and then the two ends of the balloon will be respectively sent into the inner sides of the two clamping sleeves 5, and then the matching sleeve 6 is rotated in the opposite direction. The matching sleeve 6 drives the fixed rod 24 to reset along the longitudinal groove 23 through cooperation with the sliding sleeve 8, and then the fixed rod 24 drives the guide sleeve 9 to move, and then the guide sleeve 9 drives the movable block 7 to move through the guide block 26 and the guide groove 25.

At the same time, the movable block 7 will drive the push spring 19 and the clamping plate 20 to move, and then the clamping plate 20 will be close to the balloon. Then the movable block 7 will squeeze the push spring 19, so that the clamping plate 20 clamps the two ends of the balloon, and then the rotation of the matching sleeve 6 is stopped. Then the rotating plate 12 is rotated again, so that the rotating plate 12 drives the yield groove 15 to move to the position corresponding to the limit plate 13, and then the spring 16 pushes the limit sleeve 11 to drive the limit frame 10 and the limit plate 13 to reset. When the spring 16 is fully reset, the inner wall of the limit sleeve 11 limits the outer side of the limit rod 17 again to prevent the limit rod 17 from moving, and then the limit rod 17 and the limit groove 14 cooperate to limit the matching sleeve 6.Prevent the matching sleeve 6 from rotating, and then rotate the rotating plate 12 again, which drives the clearance groove 15 to move to a position that does not correspond to the limit plate 13, so that the limit plate 13 and the limit frame 10 cooperate to limit the limit sleeve 11, preventing the limit sleeve 11 from moving, thereby ensuring a stable clamping function.

[0038] See also Figure 1-2 As a further embodiment of the medicine applicator: a mounting seat 27 is provided on both the fixed seat 1 and the movable seat 4, and the mounting seat 27 is detachably mounted on the top of the fixed seat 1 and the movable seat 4 respectively by bolts.

[0040] A bracket 31 is provided on the outside of the fixing seat 1 , and a medicine applicator assembly 32 is movably provided on the bracket 31 .

[0041] More specifically, when the device needs to be used, first clamp the multiple balloons separately and stably, then turn on the motor 28, the motor 28 drives the screw 3 to rotate, and then the movable seat 4 drives the slider 30 to slide along the slide rail 29. At the same time, the movable seat 4 will drive the clamping device installed above to move and tighten the balloon, and then turn off the motor 28, and use the external delivery device to deliver the drug to the coating assembly 32 installed on the bracket 31, and then turn on the external driving device to drive the coating assembly 32 to move, so that the coating assembly 32 completes the coating process on the balloon.

[0042] In summary, when the entire device is in use or running: when the balloon needs to be stably clamped, first rotate the rotating plate 12, and then the rotating plate 12 will drive the give way slot 15 to move. When the give way slot 15 moves to the position corresponding to the limit plate 13, push the limit sleeve 11, and the limit sleeve 11 drives the limit frame 10 and the limit plate 13 to move. At the same time, the limit sleeve 11 will cooperate with the rotating plate 12 to squeeze the spring 16. When the spring 16 is squeezed to the limit, the corresponding limit plate 13 just passes through the give way slot 15 and moves to the side of the rotating plate 12. Then rotate the rotating plate 12 again, and the rotating plate 12 drives the give way slot 15 to move to a position that does not correspond to the limit plate 13, so that the limit sleeve 11 is engaged with the rotating plate 12 through the limit frame 10 and the limit plate 13. On one side, at the same time, the outer side of the limiting rod 17 loses the limit of the limiting sleeve 11, and then the matching sleeve 6 is rotated, and the matching sleeve 6 drives the limiting rod 17 to move. Due to the rounded structural design at the end of the limiting rod 17 and the edge of the limiting groove 14, and the conical spring 18 only provides a weak reset force, then the side wall of the limiting groove 14 squeezes the side wall of the limiting rod 17, so that one end of the limiting rod 17 slides out of the limiting groove 14, and at the same time, the other end of the limiting rod 17 drives the conical spring 18 to stretch. At the same time, since the inner wall of the rotating sleeve and the outer side of the sliding sleeve 8 are movably connected by threads, and the longitudinal groove 23 limits the fixed rod 24, then the sliding sleeve 8 will drive the fixed rod 24 to slide along the longitudinal groove 23, and then the fixed rod 24 drives the guide sleeve 9 to slide, and the guide sleeve 9 passes through the guide block 26 and The guide groove 25 drives the movable block 7 to move, and then the movable block 7 drives the movable plate 22 to slide along the movable groove 21. Due to the inclined structural design of the movable groove 21 and the movable plate 22, the movable plate 22 drives the movable block 7 to spread outward while sliding. At the same time, the movable block 7 drives the push spring 19 and the clamping plate 20 set on the other side to move outward, and then the two ends of the balloon are respectively sent into the inner sides of the two clamping sleeves 5, and then the matching sleeve 6 is rotated in the opposite direction. The matching sleeve 6 drives the fixed rod 24 to reset along the longitudinal groove 23 through cooperation with the sliding sleeve 8, and then the fixed rod 24 drives the guide sleeve 9 to move, and then the guide sleeve 9 drives the movable block 7 to move through the guide block 26 and the guide groove 25, and the movable block 7 drives the movable plate 22 to reset along the movable groove 21, and then the movable When the movable plate 22 moves along the movable groove 21, it drives the movable block 7 to gather inward, and then the movable block 7 will drive the guide block 26 to slide along the guide groove 25. At the same time, the movable block 7 will drive the push spring 19 and the clamping plate 20 to move, and then the clamping plate 20 will be close to the balloon, and then the movable block 7 will squeeze the push spring 19 so that the clamping plate 20 clamps the two ends of the balloon, and then the rotation of the matching sleeve 6 is stopped, and then the rotating plate 12 is rotated again, so that the rotating plate 12 drives the yield groove 15 to move to the position corresponding to the limit plate 13, and then the spring 16 pushes the limit sleeve 11 to drive the limit frame 10 and the limit plate 13 to reset. When the spring 16 is fully reset, the inner wall of the limit sleeve 11 limits the outer side of the limit rod 17 again to prevent the limit rod 17 from moving.Then, the limiting rod 17 and the limiting groove 14 cooperate to limit the mating sleeve 6, preventing the mating sleeve 6 from rotating. Then, the rotating plate 12 is rotated again, and the rotating plate 12 drives the giving groove 15 to move to a position that does not correspond to the limiting plate 13. Therefore, the limiting plate 13 and the limiting frame 10 cooperate to limit the limiting sleeve 11, preventing the limiting sleeve 11 from moving, thereby ensuring a stable clamping function.
