[0003] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It involves draining blood from the body and passing it through a dialyzer composed of numerous hollow fibers. The blood exchanges substances with an electrolyte solution (dialysis fluid) containing a concentration similar to that in the body through diffusion / convection inside and outside the hollow fibers, removing metabolic waste and maintaining electrolyte and acid-base balance. In the automated production process of dialysis tubing, the tubing must be kept safe and clean, and human contact should be minimized.

[0028] An automatic dialyzer feeding mechanism proposed in this application includes: a alignment component 1, which includes a conveyor belt, a first bracket 11, a light sensor, a cylinder 12, and a pressure plate 13. The first bracket 11 is located at the end of the conveyor belt, and cylinders 12 are located at both ends of the first bracket 11. The output end of the cylinder 12 is fixed to the pressure plate 13, and the light sensor is located on the first bracket 11; and a robotic arm component 2, which includes a Y-axis transmission component 21, a Z-axis transmission component 22, a connecting rod 24, and an adsorption-rotation component 23. The Y-axis transmission component 21 includes a first guide rail 211, a first slider 212, and a first motor 213. The first slider 212 moves along the first guide rail 211, and the output shaft of the first motor 213 is fixedly connected to the first slider 212. The connecting rod 24 is fixedly connected to the first slider 212. The Z-axis transmission component 22 includes a second guide rail 221, a first guide rail 222, a first guide rail 23, a second guide rail 24, a third guide rail 25, a fourth guide rail 26, a fifth guide rail 27, a sixth guide rail 28, a seventh guide rail 29, a 10-degree angle rod 20, a 11-degree angle rod 212, a 11-degree angle rod 212, a 12 ... The assembly consists of two sliders 222 and a second motor 223. A second guide rail 221 is mounted on a connecting rod 24. The second slider 222 moves along the second guide rail 221. The output shaft of the second motor 223 is fixedly connected to the second slider 222. The adsorption rotation assembly 23 includes a rotary motor 231, a vacuum device 232, a bracket 233, and a suction nozzle 234. The vacuum device 232 is fixedly connected to the second slider 222 via a connector. The rotary motor 231 is fixed below the vacuum device 232. The output shaft of the rotary motor 231 is connected to the bracket 233. The suction nozzle 234 is fixed below the bracket 233. The vacuum device 232 is connected to the suction nozzle 234 via a connecting pipe. A main conveyor line 3 includes a frame, a belt, rotating rollers, a second bracket, and a drive motor. Rotating rollers are located at both ends of the belt and are fixedly connected to the drive motor. The second bracket is mounted on the belt. Figure 1 As shown in this embodiment, an automatic dialyzer feeding mechanism is proposed. The first bracket 11 in the alignment component 1 is used to receive the dialysis tubing conveyed by the conveyor belt. After the photosensitive sensor at the bottom of the first bracket 11 receives a signal, the controller controls the cylinder 12 to move, and the pressure plate 13 adjusts the position of the dialysis tubing. Through the alignment component 1, the contact position between the suction nozzle 234 of the robotic arm component 2 and the dialysis tubing on the first bracket 11 is kept consistent each time, thus achieving a higher degree of standardization and normalization.
[0029] The robotic arm component 2 includes a Y-axis transmission component 21 that drives the connecting rod 24 to move along the Y-axis. A Z-axis transmission component 22 is mounted on the connecting rod 24, which drives the adsorption rotation component 23 to move along the Z-axis. After the vacuum device 232 operates, the suction nozzle 234 adsorbs and grasps the dialysis tube. Then, the rotary motor 231 drives the support 233 to rotate. The rotation angle is adjustable according to the orientation of the main conveyor line 3. Figure 1In the process, the main production line is oriented along the X-axis, so the rotation angle of the rotary motor 231 is 90°, realizing the transformation of the dialysis tube from moving along the Y-axis to moving along the X-axis.
[0030] In some embodiments of this application, the automatic feeding mechanism further includes an auxiliary bracket 4. The auxiliary bracket 4 has a connecting frame 41, a third guide rail 42, a third slider 43, a bracket support plate 44, a third bracket 45, and a third motor. The connecting frame 41 is fixedly connected to both ends of the frame. The third guide rail 42 is arranged on the connecting frame 41 along the Z-axis. The output shaft of the third motor is fixedly connected to the third slider 43, and the third slider 43 moves along the third guide rail 42. The bracket support plate 44 is fixedly connected to the third slider 43, and the third bracket 45 is arranged on the bracket support plate 44. The auxiliary bracket 4 uses the third bracket 45 of the bracket support plate 44 to receive the dialysis tubes transmitted from the robotic arm assembly 2. Driven by the third motor, the bracket support plate 44 can move up and down along the Z-axis, placing the dialysis tubes from the third bracket 45 to the second bracket. The auxiliary bracket 4 performs fixed-point delivery of the dialysis tubes, resulting in a high degree of automation of the entire device.
[0031] Specifically, there is a gap in the center of the belt, which allows the bracket support plate 44 to enter the belt gap. By adjusting the height of the third bracket 45, when the height of the third bracket 45 is lower than the height of the second bracket, the dialysis tube is placed on the second bracket. At this time, the controller controls the drive motor to work, the belt moves forward, and the third motor works to lift the bracket support plate 44 upward, completing one transfer of the dialysis tube.
[0032] Specifically, the belt consists of two belts arranged parallel to each other along the length of the frame, with a gap between them. The second brackets are evenly distributed on the belts. The second brackets are evenly spaced on the belts. In this application, the first bracket 11, the second bracket, and the third bracket 45 are all arranged in a pair, with a certain distance maintained between adjacent second brackets. This allows the auxiliary brackets 4 to have sufficient spacing during positioning, placement, and removal, ensuring the safe transfer of the dialysis tubing.
[0033] Among them, the second bracket is arranged in multiple parallel rows above the belt along the X-axis.
[0034] The length of the third bracket 45 is less than the length of the second bracket, and the width of the bracket support plate 44 is less than the width of the gap. To ensure better cooperation between the third bracket 45 and the second bracket, the length of the third bracket 45 is designed to be less than the length of the second bracket. This ensures that after the third bracket 45 moves downward, both ends of the dialysis tube cooperate with the second bracket. As the bracket support plate 44 moves downward, the third bracket 45 separates from the dialysis tube. At this time, the drive motor works, the second bracket moves forward, and the third motor works to lift the bracket support plate upward, completing one transfer of the dialysis tube.
[0035] The width of the bracket support plate 44 is smaller than the width of the gap, which is to facilitate the smooth entry of the bracket support plate 44 into the gap and provide support for the cooperation between the third bracket 45 and the second bracket.
[0036] Specifically, a position sensor is provided above the belt and at the bottom of the bracket support plate 44. The position sensor helps to position the third bracket 45 on the auxiliary bracket 4 relative to the second bracket on the belt. The position sensor can also be located at the connecting frame 41, depending on actual working requirements and ease of installation. Once the position sensors are in position, the drive motor stops driving the belt to move, at which point the second bracket on the belt and the third bracket 45 on the auxiliary bracket 4 are perpendicular to each other.
[0037] Furthermore, the automatic feeding mechanism also includes a power supply and a controller. The power supply is electrically connected to the light sensor, cylinder 12, first motor 213, second motor 223, third motor, rotary motor 231, vacuum device 232, drive motor, and position sensor. The controller is used to receive electrical signals from the light sensor and position sensor, and to control the operation of the cylinder 12, first motor 213, second motor 223, third motor, rotary motor 231, vacuum device 232, and drive motor.
[0038] In use, the first bracket 11 in the alignment component 1 is used to support the dialysis tubes conveyed by the conveyor belt. After the photosensitive sensor at the bottom of the first bracket 11 receives a signal, the controller controls the cylinder 12 to move, and the pressure plate 13 is used to adjust the position of the dialysis tube. In the robotic arm component 2, after the vacuum device 232 is working, the suction nozzle 234 adsorbs and grasps the dialysis tube. The Y-axis transmission component 21 can drive the connecting rod 24 to move along the Y-axis, and the connecting rod 24 is equipped with a Z-axis transmission component 22. The Z-axis transmission component 22 can drive the adsorption rotation component 23 to move along the Z-axis. Then, the rotary motor 231 drives the support 233 to rotate, so as to realize the cooperation between the dialysis tube and the third bracket 45. The auxiliary bracket 4 uses the third bracket 45 of the bracket support plate 44 to receive the dialysis tube transferred from the robotic arm assembly 2. The third motor works, and the bracket support plate 44 can move up and down along the Z-axis, placing the dialysis tube from the third bracket 45 to the second bracket. The auxiliary bracket 4 is used to place the dialysis tube at a fixed point. After the transfer is completed, the third motor lifts the bracket support plate 44 upward, the rotary motor 231 returns to its position, and under the drive of the Y-axis transmission assembly 21 and the Z-axis transmission assembly 22, the adsorption rotary assembly 23 grabs the dialysis tube again. The device has a high degree of automation.
[0039] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
