Definitions

  • the disclosed embodiments relate generally to a pump to pump fluids, and more particularly to a peristaltic pumping devices, methods, and systems that have favorable properties in many applications, particularly in applications for a compact and/or portable devices.
  • Peristaltic pumps are used for transferring various fluids including gases, viscous liquids, and mixed phase fluids such as gas/liquid and solid/liquid combinations, in various applications where sanitary conditions apply and where the fluid-carrying tubing has to be changed frequently.
  • Peristaltic pumps are common in many different fields such as the medical, pharmaceutical, chemical, and environmental industries, as well as other fields where the purity of the fluid during transmission needs to be maintained.
  • a peristaltic pump typically includes a rotary assembly (rollers) which compels the movement of a fluid by peristaltic compression of the resilient tubes containing the fluid against a rigid surface of the pump known as the pump occlusion. The intersection between the rollers and the occlusion region is known as the operating area of the pump. In operation, the rotating rollers exert pressure on the flexible tubing to propel the fluid, and the negative pressure formed when the tubing returns to its normal position sucks the fluid from a fluid source and forces the fluid to travel continuously through the tubing.
  • peristaltic pumps may provide a mechanism for regulating the pinching force of the rollers exerted on the tubing.
  • the environment of compact and light weight devices and systems creates a need for improvements in the design of peristaltic pumps that provides advantages in terms of usability, reliability, and addresses the other requirements of peristaltic pumps such as maintenance and regulation such as those mentioned above.
  • a peristaltic pump with a removable pump race module has guiding channels for receiving at least a portion of a flexible fluid-carrying tubing and an adjusting device for displacing a flexible inner portion of the removable pump race module to change the compression on the fluid-carrying tubing.

  • a distal end plate 40 provided with screws 41 for attachment to the support base 20.
  • the outer pump race module 10 has at least one pump race arch 16 (shown in Fig. 15A) that partially surrounds a roller carriage 50 (shown in Fig. 7) positioned in the working area 70 of the pump so that the outer pump race module 10 together with the support base 20 and the distal end plate 40 effectively enclose the working area 70 of the pump.
  • the removable pump race module 10 can be securely mounted on the support base 20 using any suitable fasteners 11 , such as, bolts, screws, cap screws, rivets, etc, inserted in corresponding support guides 12.
  • the support guides 12 help to ensure alignment of the race module 10 with respect to the base 20, however a broad mating surface on race module 10 that adjoins a mating surface on the base 20 could be used for this purpose as well as other mechanisms.

  • the adjusting screw 13B exerts a force to separate a race portion 16B and support portion 16A of the pump race arch 16 thereby opening and closing the gap 10G in the pump race module 10. Since the support portion 16A is fixed relative to the pump and roller carriage 50, this adjustment determines the force applied by the pump race surface 17 of the pump race portion 16B against the tubing and compensated by the pump roller carriage 50.

  • the drive shaft 31 rotates a pump roller carriage 50 with an array of equidistant and circumferentially spaced compression rollers 52.
  • Each of the compression rollers 52 rotate about respective shafts 53 which are rotatably secured at respective ends thereof to rotor end plates 51.
  • the rotor end plates 51 are configured to engage a flat 31 A of the drive shaft 31 so that they are rotated by the motor 30 (see Figs. 12-14).
  • the rotation of the drive shaft 31 drives the compression rollers 52, which selectively compress a fluid-carrying tube 60 (see Fig. 15B) so as to effect peristaltic pumping.

  • the roller carriage 50 is secured at one end to the mounting plate 22 of the support base 20, and at the other end to the end plate 40.

By moving the lower curved portion 16B closer to the roller carriage 50, the fluid-carrying tubing 60 positioned in the guiding channels 18 is further compressed. When the pressure on the contact surface of the lower curved portion 16B is released, the curved portion 16B moves back to its original position, releasing compression on the fluid-carrying tubing 60. Changing compression on the tubes 60 incorporating the fluid effectively controls the fluid pressure and fluid flow in the tubing 60.
  • the pump race force adjuster 13 can include, for example, a threaded liner 13A with adjusting screw13B so that the fluid pressure and fluid flow is controlled by turning the screw head.
