Abstract: A fluid handling cassette (24), such as that useable with an APD cycler device or other infusion apparatus, may include a generally planar body having at least one pump chamber (181) formed as a depression in a first side of the body and a plurality of flowpaths for fluid that includes a channel. A patient line port may be arranged for connection to a patient line (34) and be in fluid communication with the at least one pump chamber via at least one flowpath, and an optional membrane (15) may be attached to the first side of the body over the at least one pump chamber. In one embodiment, the membrane may have a pump chamber portion (151) with an unstressed shape that generally conforms to the pump chamber depression in the body and is arranged to be movable for movement of fluid in the useable space of the pump chamber. One or more spacers (50) may be provided in the pump chamber to prevent a pump membrane from contacting an inner wall of the pump chamber. Patient, drain (28) and/or heater bag lines (26) may be positioned to be separately occludable in relation to one or more solution lines (30) that are connectable to the cassette.

Abstract: A medical treatment system, such as peritoneal dialysis system, may include control and other features to enhance patient comfort and ease of use. For example, a peritoneal dialysis system may include patient line state detector for detecting whether a patient line is primed before it is to be connected to the patient. The patient line state detector can also the ability to detect whether a patient line has been properly mounted for priming. Both patient line presence/absence and fill state can be determined using an optical system, e.g., one that employs a single optical sensor.

Abstract: Un oclusor, y métodos para oclusión, que utiliza primer y segundo miembros de oclusión opuestos asociados uno con otro, un miembro de contacto con el tubo conectado a, o que comprende por lo menos una porción de, por lo menos uno del primer y segundo miembros de oclusión, y un accionador de fuerza construido y ubicado para aplicar una fuerza a por lo menos uno del primer y segundo miembros de oclusión; la aplicación de la fuerza por el accionador de fuerza puede causar que el miembro de contacto con el tubo se mueva entre una posición de oclusión de tubo y una posición abierta; un miembro de liberación puede estar configurado y ubicado para permitir a un operador mover manualmente el miembro de contacto con el tubo de la posición de oclusión del tubo a la posición abierta incluso sin fuerza aplicada al miembro de oclusión por el accionador de fuerza; en una modalidad, el accionador de fuerza puede aplicar una fuerza suficiente para doblar tanto el primer como el segundo miembros de oclusión, de modo que bajo aplicación de la fuerza por el accionador de fuerza (tal como una vejiga de aire), el primer y segundo miembros de oclusión (v.gr., placas de resorte pivotalmente conectadas en extremos opuestos) se doblan y el miembro de contacto con el tubo puede moverse entre una posición de oclusión de tubo y una posición abierta.

Abstract: The present application provides a fluid handling cassette for use with a peritoneal dialysis system. The cassette comprises a generally planar body, at least one pump chamber in a first side of the body, and a plurality of flowpaths for fluid; a spike located at a first end of the body for engagement with a dialysate solution line, and in fluid communication with the at least one pump chamber via at least one flowpath and comprising a distal tip and a lumen. The distal tip of the spike can be positioned at or near the longitudinal axis of the spike and the lumen can be positioned off the longitudinal axis of the spike, which runs along the geometric center of the spike. The positioning of the spike tip may help ease alignment tolerances when engaging the spike with a corresponding solution line, and for puncturing a septum or membrane.

Abstract: A medical treatment system, such as peritoneal dialysis system, may include control and other features to enhance patient comfort and ease of use. For example, a peritoneal dialysis system may include a control system that can adjust the volume of fluid infused into the peritoneal cavity to prevent the intraperitoneal fluid volume from exceeding a predetermined amount. The control system can adjust by adding one or more therapy cycles, allowing for fill volumes during each cycle to be reduced. The control system may continue to allow the fluid to drain from the peritoneal cavity as completely as possible before starting the next therapy cycle. The control system may also adjust the dwell time of fluid within the peritoneal cavity during therapy cycles in order to complete a therapy within a scheduled time period. The cycler may also be configured to have a heater control system that monitors both the temperature of a heating tray and the temperature of a bag of dialysis fluid in order to bring the temperature of the dialysis fluid rapidly to a specified temperature, with minimal temperature overshoot.
