Abstract: A peristaltic pump has a pump rotor (292) rotatable about an axis. The pump rotor carries a pump roller (300). An actuating rod (308) extends along the axis of rotation. The rod has a distal end and a proximal end. An actuator mechanism (310) is coupled to the proximal rod end for advancing the rod along the axis of rotation in a forward direction toward the pump rotor and in a rearward direction away from the pump rotor. A linkage mechanism (314, 322) is coupled to the distal rod end for converting advancement of the actuating rod along the axis of rotation in response to the actuator mechanism (310) into movement of the pump roller (300) radially of the axis of rotation between a retracted position free of contact with pump tubing and an extended position making operative contact with pump tubing (134, 136).

Abstract: A peristaltic pumping apparatus (100) includes a pump rotor (116) carrying a roller and a drive mechanism for rotating the rotor. The drive mechanism includes a carrier (128) for holding the pump rotor. The apparatus includes a release pin mechanism carried on the pump rotor and exposed to access by a user. The release pin mechanism is movable by the user between a first position that connects the pump rotor to the carrier and a second position that disconnects the pump rotor from the carrier. Placing the release pin mechanism in the second position allows quick separation of the pump rotor from the drive mechanism.

Abstract: A peristaltic pump includes a pump race for receiving a flexible tubing. A rotatable pump rotor (292) carries at least one roller (300) for contacting the tubing (134/136). A roller locating mechanism (306) moves the pump roller between a retracted position for free contact with the tubing and an extended position making operative contact with the tubing. A controller (246) operates the pump (i) in a pumping mode, during which the rotor (292) is rotated with the roller (300) located in its extended position, and (ii) in a valving mode, during which rotation of the rotor is terminated and the roller is selectively moved between its extended position to block fluid flow through the tubing and its retracted position to permit fluid flow through the tubing. The pump thus provides a peristaltic pump pumping function, as well as serving as a valve element.

Abstract: A self-loading peristaltic pumping apparatus includes a pump race (296) for receiving a tubing loop, a pump rotor (298) carrying a roller (300), and a drive mechanism for rotating the rotor within the pump race. The apparatus also includes a roller locating mechanism (306) that moves the pump roller between a retracted position, free of contact with the received tubing loop (134, 136), and an extended position, at least partially within the pump race for operative contact with the received tubing loop. The apparatus includes at least one tubing guide element (304) carried by the rotor. The guide element extends from the rotor at least partially into the pump race. The guide element serves during rotation of the rotor with the roller in its retracted position, for contacting the received tubing loop (134, 136) to orient the tubing loop within the pump race.

Abstract: A compact pump assembly includes a plurality of axially aligned peristaltic pumps (112-118) for activating the flow of liquids through the conduits (44). A housing containing the pumps is provided with a removable cover (14) for retaining the pumps in the housing when the cover is closed, and for permitting removal of the pumps when the cover is opened. A reversible motor (132, 134) is mounted outside of the housing for driving each of the pumps. The pumps may be independently inactivated by individual release mechanisms provided on the common closure cover.

Abstract: A peristaltic pump tube holder has a body having first and second pump tube connectors extending outside of it. The pump tube connectors extend at an acute angle relative to a surface of the body to receive a flexible tubing loop and orient the tubing loop for engagement with an external peristaltic pump rotor.
