Description

Technical Field

[0001] This utility model relates to an infusion set coil device. Background Technology

[0002] An infusion set refers to a disposable infusion set, a common medical consumable. It is sterilized and establishes a channel between a vein and the medication for intravenous infusion. It generally consists of eight connected parts: an intravenous needle or injection needle, a needle cap, an infusion tubing, a medication filter, a flow regulator, a drip chamber, a stopper puncture device, and an air filter. Some infusion sets also include an injection port and a medication dispensing port.

[0003] The infusion tubing and other parts of the infusion set are assembled using infusion set assembly equipment. This equipment has multiple assembly stations. Once the infusion tubing is assembled with one station, it is moved to the next station by a feeding device until the entire infusion set is assembled. Since the main body of the infusion set is the infusion tubing, it is very easy for it to become tangled and twisted. To avoid this, the assembled infusion set needs to be coiled into a regular loop shape. This prevents the infusion tubing from deforming or being damaged due to its own tangling. However, the coiling of the infusion set is usually done manually by workers. The speed of manual coiling is extremely limited, and as the coiling time increases, workers inevitably become fatigued, leading to a further decrease in coiling speed. This makes it impossible to maintain high coiling efficiency. At the same time, the diameter of the loop structure formed by each coil cannot be consistent, affecting the coiling quality and hindering subsequent packaging work. Summary of the Invention

[0030] The upper end face of the front tensioning wheel 35 and the rear tensioning wheel 34 are each provided with an upper groove 36 at the center, and the lower end face of the front tensioning wheel 35 and the rear tensioning wheel 34 are provided with a lower groove 37 at the center; the center of the bottom of the upper groove 36 and the center of the bottom of the lower groove 37 are connected by a shaft hole 38; a matching axle 39 is provided in the shaft hole 38; the upper end of the axle 39 extends upward to the outside of the upper groove 36 and is provided with a limiting head 40; a lower screw hole 41 is provided at the center of the lower end face of the axle 39; an upper screw hole 42 is provided at the center of the upper surface of the limiting head 40.

[0031] The upper rear surface of the seat plate 1 is provided with symmetrical guide plates 43 on both sides; the front side wall of the guide plate 43 is provided with a slide rail 44; the rear side wall of the lifting plate 4 is provided with sliders 45 that match the slide rail 44 on both sides.

[0032] A fixing plate 46 is provided on the rear side wall of the guide plate 43; the fixing plates 46 on the left and right sides are connected by a connecting plate 47; the left and right sides of the rear side wall of the connecting plate 47 are provided with symmetrical upper cylinders 48; the upper end of the piston rod of the upper cylinder 48 is provided with an upper plate 49; the upper surface of the upper plate 49 is provided with a matching locking bracket 50.

[0033] The method of using this utility model is as follows:

[0034] After the infusion set is assembled, it will be moved by the feeding device of the infusion set assembly equipment to the top of the positioning frame 50. At this time, the drip chamber 5101 of the disposable infusion set 51 faces forward, while the infusion tubing 5102 is straightened from front to back. When the feeding device moves the drip chamber 5101 of the infusion set 51 to the top of the positioning frame 50, the upper cylinder 48 is activated. The piston rod of the upper cylinder 48 will drive the upper plate 49 to move upward, thereby realizing the upward movement of the positioning frame 50. As the positioning frame 50 moves upward, the drip chamber 5101 is just inserted into the matching positioning groove 5001 on the positioning frame 50, thereby lifting the drip chamber 5101. At this time, the clamping mechanism on the feeding device releases the drip chamber 5101, and then uses other corresponding clamping mechanisms to clamp the drip chamber 5101 stuck in the positioning groove 5001 and move it towards the position of the second pneumatic finger 14.

[0035] Once the dripper is moved directly above the second pneumatic finger 14, the lifting cylinder 2 can be activated. The piston rod of the lifting cylinder 2 will drive the lifting plate 4 to move upward. As the lifting plate 4 moves upward, the second pneumatic finger 14 also moves upward. When the second pneumatic finger 14 moves to the required height, the middle part of the dripper 5101 held by the clamping mechanism is exactly between the clamping arms 15 on the gripper of the second pneumatic finger 14. In order for the clamping arms 15 to better grip the dripper 5101, an arc-shaped groove 1501 can be provided on the opposite side of the left and right clamping arms 15. When the gripper of the second pneumatic finger 14 drives the left and right clamping arms 15 to move closer and close together, the dripper 5101 is just clamped in the arc-shaped groove 1501 on the left and right clamping arms 15. At this time, the clamping mechanism releases the dripper 5101 and resets, so as not to interfere with the subsequent coil operation.

[0036] When the drip chamber 5101 is clamped by the gripper arm 15 on the second pneumatic finger 14, part of the infusion tubing 5102 is positioned on the upper right surface of the support plate 23. Lifting the infusion tubing 5102 allows for adjustment of the front-to-back distance between the front support rod 18 and the rear support rod 22 before actual coiling. This effectively controls the diameter of the infusion set after coiling into a ring structure. To adjust the distance between the front support rod 18 and the rear support rod 22, simply activate the first pneumatic finger 10. When the first pneumatic finger 10 controls the grippers on its front and rear sides... As they approach each other, the distance between the front plate 11 and the rear plate 12 decreases. When the first pneumatic finger 10 controls the grippers on its front and rear sides to move away from each other, the distance between the front plate 11 and the rear plate 12 increases. The front movable plate 17 moves synchronously with the front plate 11, and the rear movable plate 21 moves synchronously with the rear plate 12, thereby realizing the movement of the front support rod 18 and the rear support rod 22. This effectively changes the front-to-back distance between the front support rod 18 and the rear support rod 22. The greater the front-to-back distance between the front support rod 18 and the rear support rod 22, the larger the diameter of the infusion set 51 after it is coiled into a ring structure.

[0037] After the distance between the front support rod 18 and the rear support rod 22 is adjusted, the motor can be started. At this time, the motor shaft of the motor 31 will drive the drive wheel 32 to rotate. The drive wheel 32 is connected to the driven wheels 16 distributed on the left and right sides below the lifting plate 4 through the synchronous belt 33. When the drive wheel 32 rotates, the driven wheels 16 rotate accordingly. The driven wheels 16 are located on the lower end of the rotating shaft 7. Therefore, when the driven wheels 16 rotate, the rotating shaft 7 rotates synchronously. The rotating shaft 7 will drive the first pneumatic finger 10 located on the upper surface of the rotating plate 9 to rotate, thereby realizing the rotation of the front support rod 18 and the rear support rod 22. At the same time, The second pneumatic finger 14 rotates synchronously with the first pneumatic finger 10 via the fixed base 13. When the drip chamber 5101 is clamped by the second pneumatic finger 14, it is equivalent to one end of the infusion set 51 being fixed. As the front support rod 18 and the rear support rod 22 rotate, the infusion set 51 will continuously coil around the outer ring of the front support rod 18 on the left and right sides in front and the rear support rod 22 on the left and right sides behind, eventually coiling into a ring structure. During the coiling process, the support plate 23 and the support sleeve 19 can both provide support and lift the infusion set 51, effectively preventing the infusion set 51 from falling during the coiling process and affecting the quality of the coil.

[0038] After the coiling is completed, the motor 31 stops running, and the gripper of the second pneumatic finger 14 controls the gripper arm 15 to release the drip pot 5101. Then, the infusion set 51, which is coiled into a ring structure, can be removed using the subsequent clamping device. After the subsequent clamping device clamps the infusion set after the coiling is completed, the lifting cylinder 2 is activated. The piston rod of the lifting cylinder 2 drives the lifting plate 4 to move down, thereby realizing the active downward movement of the front support rod 18 and the rear support rod 22, so that the front support rod 18 and the rear support rod 22 can directly disengage from the ring structure formed by the infusion set, which is conducive to the subsequent transfer of the infusion set.

[0039] In summary, this utility model can fix one end of the infusion set 51 by using the second pneumatic finger 14, and then use the rotation of the front support rod 18 distributed on the front left and right sides and the rear support rod 22 distributed on the rear left and right sides to coil the infusion set 51 with one end fixed, so that the infusion set 51 continuously rotates around the front support rod 18 and the rear support rod 22, and finally coils into a ring structure, achieving the effect of automatic coiling. The automatic coiling method does not require manual intervention, can always maintain high coiling efficiency, and the diameter of the ring structure formed after each coiling is consistent, which is beneficial for subsequent packaging.

[0040] The outer wall of the support sleeve 19 has a front screw hole 20 that communicates with its internal space. Simply tighten the screw into the front screw hole 20, and the end of the screw will press against the outer wall of the front support rod 18, thereby fixing the support sleeve 19. If the height of the support sleeve 19 needs to be adjusted, the screw in the front screw hole 20 can be loosened. As long as the end of the screw is no longer pressed against the outer wall of the front support rod 18, the support sleeve 19 can move smoothly up and down along the trajectory of the front support rod 18, thereby adjusting the position of the support sleeve 19.

[0041] The support plate 23 has sliding holes 24 on its left and right sides that match the rear support rod 22. The support plate 23 also has longitudinal cuts 25 on its left and right sides corresponding to the positions of the sliding holes 24. The front end of the longitudinal cut 25 is located on the front sidewall of the support plate 23. The rear end of the longitudinal cut 25 communicates with the right side of the sliding hole 24 through a transverse cut 26. The support plate 23 has countersunk holes 27 on its left and right sides that communicate with the transverse cuts 26. The countersunk holes 27 are adjacent to the longitudinal cuts 25. The rear inner wall of the transverse cut 26... The rear threaded hole is coaxial with the countersunk hole 27. When it is necessary to fix the support plate 23 and the rear support rod 22, the screw can be passed through the countersunk hole 27 and the transverse cut 26 in sequence and screwed into the rear threaded hole. When it is necessary to change the vertical position of the support plate 23, simply loosen the screw. The elasticity formed by the transverse cut 26 and the longitudinal cut 25 allows the support plate 23 to move up and down along the rear support rod 22 through the sliding hole 24, thereby changing the position of the support plate 23. After the position adjustment is completed, tighten the screw.

[0042] The lower rear surface of the lifting plate 4 is provided with symmetrical rear tensioning rollers 34 on both sides, and the lower front surface of the lifting plate 4 is provided with a front tensioning roller 35 at the center. Both the front tensioning roller 35 and the rear tensioning roller 34 are in contact with the outer wall of the synchronous belt 33. The presence of the front tensioning roller 35 and the rear tensioning roller 34 can effectively ensure the tension of the synchronous belt and avoid the situation where the synchronous belt 33 is loose and the driving wheel 32 cannot drive the driven wheel 16 to rotate synchronously.

[0043] The upper end face of both the front tensioning wheel 35 and the rear tensioning wheel 34 is provided with an upper groove 36, and the lower end face of both the front tensioning wheel 35 and the rear tensioning wheel 34 is provided with a lower groove 37. The center of the bottom of the upper groove 36 and the center of the bottom of the lower groove 37 are connected by a shaft hole 38. A matching axle 39 is provided in the shaft hole 38. The upper end of the axle 39 extends upward to the outside of the upper groove 36 and is provided with a limiting head 40. The center of the lower end face of the axle 39 is provided with a lower screw hole 41, and the center of the upper surface of the limiting head 40 is provided with an upper screw hole 42. The upper screw hole 42 can be used to screw in screws. The lifting plate 4 can be provided with a round hole 401 or an oblong hole 402 corresponding to the position of the upper screw hole 42, so that the screw can pass through. The round hole 401 or the oblong hole 402 is then screwed into the upper screw hole 42, and the head of the screw presses against the upper surface of the lifting plate 4 to fix the wheel axle 39. The presence of the oblong hole 402 allows for the adjustment of the position of the wheel axle 39, thereby changing the position of the front tensioning wheel 35 or the rear tensioning wheel 34. When the timing belt 33 is loose, the front tensioning wheel 35 or the rear tensioning wheel 34 can use its own position change to restore the timing belt to the tensioned state. At the same time, the lower screw hole 41 can also be used to screw in the screw. The head of the screw and the limiting head restrict the up and down movement of the front tensioning wheel 35 and the rear tensioning wheel 34, so that the front tensioning wheel 35 and the rear tensioning wheel 34 can only rotate around the wheel axle 39.

[0044] The upper rear surface of the seat plate 1 is provided with symmetrical guide plates 43 on the left and right sides. The front side wall of the guide plate 43 is provided with a slide rail 44. The left and right sides of the rear side wall of the lifting plate 4 are provided with sliders 45 that match the slide rail 44. The existence of the slide rail 44 can play a guiding role when the lifting plate 4 moves up and down, further ensuring the stability when the infusion set is coiled.
