Abstract

A method of prolonging the life of a peristaltic pump, including setting a timer for a predetermined rest time after the peristaltic pump is used, transmitting a micro pulse to a motor of the peristaltic pump after the predetermined rest time has elapsed, and shifting a motor roller from an initial position to a second position so that a pinch point of a tube of the peristaltic pump is formed in the second position. Further, a non-transitory computer readable storage medium storing instructions that cause the one or more computers to set a timer for a predetermined rest time after the peristaltic pump is used, transmit a micro pulse to a motor after the predetermined rest time has elapsed. and shift a motor roller from an initial position to a second position so that a pinch point of a tube of the peristaltic pump is formed in the second position.

  5. 5. The method of any one of Claims 1-4, wherein the method further comprises: resetting a second timer for a rotation time a predetermined number of times; transmitting a micro pulse of a plurality of micro pulses to the motor each time the rotation time elapses; and shifting the motor roller to a new position so that a pinch point of the tube of the peristaltic pump is formed in the new position each time the micro pulse of the plurality of micro pulses is received by the motor.
  6. 6. The method of any one of Claims 1-5, wherein the method further comprises: setting a second timer for a rotation time; after the rotation time has elapsed, transmitting a second micro pulse to the motor; and shifting the motor roller from the second position to a third position so that a pinch point of the tube of the peristaltic pump is formed in the third position.
  7. 7. The method of Claim 6, wherein the third position is offset at an angle relative to the second position.
  8. 8. The method of Claim 7, wherein the angle is about 30 degrees.
  9. 9. The method of any one of Claims 6-8, wherein the method further comprises: resetting the second timer a predetermined number of times; transmitting a micro pulse of a plurality of micro pulses to the motor each time the rotation time elapses; and shifting the motor roller from the third position to a new position so that a pinch point of the tube of the peristaltic pump is formed in the new position each time the micro pulse of the plurality of micro pulses is received by the motor.
  10. 10. The method of any one of Claims 1-9, wherein the peristaltic pump is integrated into a device.
  11. 11. The method of any one of Claims 1-10, wherein the micro pulse is transmitted by a controller of the device.
  12. 12. A non-transitory computer readable storage medium storing instructions that, when executed by one or more computers, cause the one or more computers to: set a timer for a predetermined rest time; transmit a micro pulse to a motor of the peristaltic pump after the predetermined rest time has elapsed; and shift a motor roller from an initial position to a second position so that a pinch point of a tube of the peristaltic pump is formed in the second position.
  13. 13. The non-transitory computer readable storage medium of Claim 12, wherein the predetermined rest time is about 12 hours.
  14. 14. The non-transitory computer readable storage medium of Claim 12 or Claim 13, wherein the second position is offset at an angle relative to the initial position.
  15. 15. The non-transitory computer readable storage medium of Claim 14, wherein the angle is about 30 degrees.

Description

PINCHING CONTROL OF PERISTALTIC PUMPS CROSS-REFERENCES TO RELATED APPLICATIONS [0001] This application claims the benefit of U.S. Patent Application No. 18/930517, filed October 29, 2024, and French Patent Application No. 2413663, filed December 9, 2024; the contents of which are hereby incorporated by reference in their entirety for all purposes. SUMMARY [0002] In one aspect, disclosed herein is a method of prolonging the life of a peristaltic pump, the method including setting a timer for a predetermined rest time after the peristaltic pump is used, transmitting a micro pulse to a motor of the peristaltic pump after the predetermined rest time has elapsed, and shifting a motor roller from an initial position to a second position so that a pinch point of a tube of the peristaltic pump is formed in the second position. [0003] In some embodiments, the predetermined rest time is about 12 hours. [0004] In some embodiments, the second position is offset at an angle relative to the initial position. In some embodiments, the angle is about 30 degrees. [0005] In some embodiments, the method further includes resetting a second timer for a rotation time a predetermined number of times, transmitting a micro pulse of a plurality of micro pulses to the motor each time the rotation time elapses, and shifting the motor roller to a new position so that a pinch point of the tube of the peristaltic pump is formed in the new position each time the micro pulse of the plurality of micro pulses is received by the motor. [0006] In some embodiments, the method further includes setting a second timer for a rotation time, after the rotation time has elapsed, transmitting a second micro pulse to the motor, and shifting the motor roller from the second position to a third position so that a pinch point of the tube of the peristaltic pump is formed in the third position.
