Definitions

  • the field of the disclosure relates generally to peristaltic pumps. More specifically, the disclosure relates to cassettes that are readily attached and detached from the pump.
  • Peristaltic pumps have been known for many years, and are commonly used for medical and research purposes. Peristaltic pumps move a liquid through a tube without any part of the pump ever touching the liquid. As a result, it is possible to pump liquids, such as blood, which are sensitive to external contamination. Typically, a pump comprises rotating rollers that compress a part of the flexible tube as they move, which propels the liquid through the tube.
  • the pump in the aforesaid document includes removable cassettes that each include a tube and a means for securing the cassettes to the pump frame so that the tube is held against the rollers to ensure good contact between tube and rollers.
  • the means described for securing the cassettes include a notch and cam arrangement which requires two hands to operate a release lever to unlock the cassette from the pump. Additionally, a second hand simultaneously holds the cassette to prevent it from jumping off of the frame What is needed is a peristaltic pump cassette which may be easily mounted to and dismounted from a peristaltic pump using a single-hand.
  • a mechanism for mounting and dismounting a removable cassette from a peristaltic pump is provided.
  • the removable cassette is easily mounted to a pump frame of the peristaltic pump using a single-hand of a user. Additionally, a similar motion both mounts the cassette to the pump frame and dismounts the cassette from the pump frame.
