    摘要： The present invention involves, in some embodiments, mechanisms and methods of occluding collapsible tubing with an occluder to prevent fluid flow therethrough. In some embodiments, a tube occluding mechanism is disclosed that includes a bendable occluding member for creating a force that can be applied to a collapsible tube to occlude the tube. In some embodiments, the collapsible tube can be an inlet/outlet tube on a removable pumping cartridge that is coupled to a reusable pump drive component when the system is in operation. In such embodiments, the occluding mechanism can be attached to the reusable component and can be used to block fluid flow to and from the pumping cartridge. In some embodiments, the occluding member can comprises a spring plate which can create a force to occlude tubing when in a relaxed, unbent configuration, and which can be bent to unocclude the tubing. In some preferred embodiments, in a default configuration of the tube occluder mechanism (when no external force is applied to the occluding member) the tubes are occluded, so that the tube occluder mechanism provides a fail-safe configuration preventing fluid flow to and from a pumping cartridge to which the tubes can be connected.

    摘要： The present invention is directed toward a vial-loading mechanism for a system that prepares and delivers one or more IV drugs to a patient. The vial-loading mechanism is used to load a vial onto a cassette spike and includes a vertical support member located adjacent to the spike. A holding assembly holds at least one vial. The holding assembly is mounted to the support member so as to be positionable between an upper position for loading a vial and a lower position for piercing the vial with a spike. The holding assembly has an arcuate-shaped holding member for holding the vial. A catch is provided with an engagement unit for securing the holding assembly in the lower position. This arrangement provides an easy way to add, retain, and remove vials from the system and protects the clinicians that do this from contacting the spikes and hurting themselves.

    摘要： Pumping mechanisms for performing peritoneal dialysis and the like employ a pumping mechanism comprising a diaphragm that operate in response to applied fluid pressure. Flexible tubing is attached to the pumping mechanism for carrying liquid to and from the patient's peritoneal cavity. An actuating station for pumping mechanism receives the pumping mechanism and attached tubing. A pressure transfer element conveys fluid pressure to the diaphragm for moving liquid through the cassette. An occluder element contacts and crimps closed the tubing attached to the cassette. A first reservoir inflates with positive fluid pressure for contacting the pressure transfer element to hold it in operative contact against the diaphragm. A second reservoir inflates with positive fluid pressure for contacting the occluding element to hold it away from crimping contact with the tubing. At least one of the first and second reservoirs also transports fluid pressure to the pressure transfer element for conveyance to the diaphragm.

    摘要： Systems and methods for peritoneal dialysis establish flow communication between a patient's peritoneal cavity and a drain through a pump chamber having generally vertically spaced upper and lower regions andt a diaphragm. The systems and methods operate the pump chamber, with the upper and lower regions oriented generally vertically, by applying fluid pressure to the diaphragm. The systems and methods direct liquid to the patient's peritoneal cavity only from the lower region of the pump chamber. In this way, the improved systems and methods collect air in the upper region of the vertically oriented pump chamber, while isolating the patient's peritoneal cavity from air in the pump chamber.
