摘要： Described are fluid pumping and fluid handling systems, which may be suitable for use in medical devices, such as artificial or extracorporeal blood pumping systems. The systems can include a dual housing configuration for pneumatic actuation comprising a main housing containing a pump cassette comprising a pneumatically actuated pump and pneumatically actuated valves. The pump can include a pump actuation chamber and pump pneumatic port, and the valves can each include a valve actuation chamber and valve pneumatic port. Connecting tubes can be used to fluidly connect the pump actuation ports and valve actuation ports to a tube-support housing having a first side receiving one end of each connecting tube and a second side providing a pneumatic interface arranged to connect to an array of pneumatic receptacles on a base unit of the system to facilitate easy, compact and accurate pneumatic interconnection between the pump cassette and the base unit.

摘要： Improvements in fluid volume measurement systems are disclosed for a pneumatically actuated diaphragm pump in general, and a peritoneal dialysis cycler using a pump cassette in particular. Pump fluid volume measurements are based on pressure measurements in a pump control chamber and a reference chamber in a two-chamber model, with different sections being modeled using a combination of adiabatic, isothermal and polytropic processes. Real time or instantaneous fluid flow measurements in a pump chamber of the diaphragm pump are also disclosed, in this case using a one-chamber ideal gas model and using a high speed processor to obtain and process pump control chamber pressures during fluid flow into or out of the pump chamber. Improved heater control circuitry is also disclosed, to provide added or redundant safety measures, or to reduce current leakage from a heater element during pulse width modulation control of the heater element. Improvements are also disclosed in an application of negative pressure during a drain phase in peritoneal dialysis therapy, and to control an amount of intraperitoneal fluid accumulation during the therapy. Improvements in efficiency are also disclosed in movement of fluid into and out of a two-pump cassette and a heater bag of the peritoneal dialysis cycler, and in synchronization of operation of two or more pumps in the peritoneal dialysis cycler or other fluid handling devices using a multi-pump arrangement.

摘要： A fluid-handling cassette comprising a plurality of diaphragm valves and pumps is configured to have its actuation ports located along a thin or narrow edge of the cassette. Actuation channel % within the cassette lead from the actuation ports to actuation chambers of the valves and pumps in a space between plates that comprise the cassette. The individual plates have a nominal thickness that is sufficient to provide a rigid ceiling for the actuation channels, but sufficiently thin to minimize the overall thickness of the cassette. The cassette can be plugged into or unplugged from an actuation receptacle or a manifold by its narrow edge. A plurality of such cassettes can be stacked together or spaced apart from each other to form a cassette assembly, providing for a convenient way to install and remove the cassette assembly from its actuation receptacle. The arrangement allows for an improved way of connecting a complex cassette assembly to its associated pressure distribution manifold without the use of a plurality of flexible connecting tubes between the two.

摘要： A medical infusion fluid handling system, such as an automated peritoneal dialysis system, may be arranged to de-cap and connect one or more lines (such as solution lines) with one or more spikes or other connection ports on a fluid handling cassette. This feature may reduce a likelihood of contamination since no human interaction is required to de-cap and connect the one or more lines and the one or more spikes. For example, the automated peritoneal dialysis system may include a carriage arranged to receive the one or more lines each having a connector end and a cap. The carriage may move along a first direction so as to move the connector ends of the one or more lines along the first direction, and a cap stripper may be arranged to engage with the caps on the one or more lines on the carriage. The cap stripper may move in a second direction transverse to the first direction, as well as to move with the carriage along the first direction.

摘要： A method for aiding in the diagnosis of a physiological abnormality resulting in detectable, measurable variations in contents of breathed air. The system includes a handheld unit defining an airway, wherein the airway includes a plurality of sensors adapted to measure a plurality of parameters related to the presence of a physiological abnormality. The system further includes a control unit remotely connected to the handheld unit. The control unit includes a controller adapted to receive input signals from the handheld unit and remit output signals in response thereto. The output signals are usable by a user in determining the presence or absence of a physiological abnormality. The control unit further also can include a display adapted to display the output signals to a user thereby easing the determination of the physiological abnormality. The system further includes a mouthpiece selectively connectable to the handheld unit. The mouthpiece can include a filter adapted to substantially prohibit the passage of germs into the airway of the handheld unit.
