摘要： A fluid handling cassette, such as that useable with an automated peritoneal dialysis (APD) cycler device or other infusion apparatus, may include a generally planar body having at least one pump chamber formed as a depression in a first side of the body and a plurality of flowpaths for a fluid that includes a channel. A patient line port may be arranged for connection to a patient line and be in fluid communication with the at least one pump chamber via at least a first one of said flowpaths, and an optional membrane 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 with an unstressed shape that generally conforms to the depression of the at least one pump chamber in the body and is arranged to be movable for movement of the fluid in a useable space of the at least one pump chamber. One or more spacers may be provided in the at least one pump chamber to prevent the membrane from contacting an inner wall of the at least one pump chamber. The patient line, a drain line, and/or a heater bag line may be positioned to be separately occludable in relation to one or more solution lines that are connectable to the cassette.

摘要： In one example embodiment, an apparatus may include a panel with integrated fluid channels, wherein the panel and the fluid channel consist only of surfaces that can be manufactured with a straight-pull mold. A port may also be integrated into the panel to facilitate coupling the fluid channel to pneumatic components in an assembly. A seal may be secured to the panel over the fluid channel to form an integrated fluid conductor. The seal is preferably an adhesive label that can also be used for product labeling. Such an apparatus may be used in a control unit of a therapy system, employing several integrated fluid conductors. A method of manufacturing may include molding a panel, wherein the mold forms a channel integral to the panel. The panel and the channel preferably consist of surfaces that can be molded with a straight-pull mold.

摘要： A medical treatment system, such as a peritoneal dialysis system, may include a control and other features to enhance patient comfort and ease of use. For example, a cycler device may include a heater bag receiving section and a lid mounted to cover and uncover the heater bag receiving section, potentially enabling faster heating of a dialysate. A user interface may be moveable to be received into the receiving section and covered by the lid, if desired. The system may detect anomalous conditions, such as tilting of a housing of the system, and automatically recover without terminating a treatment. The system may include noise reduction features, such as porting pneumatic outputs to a common chamber, and others. The system may also automatically detect any one of several different solution lines connected to the system, and control operation accordingly, e.g., to mix solutions provided by two or more lines and form a needed dialysate solution. A cassette control surface may be arranged to have one or more ports that can detect a presence of a liquid, e.g., to identify if a cassette is leaking or has otherwise been compromised.

摘要： A method and a device for activating a function of a device, preferably of a medical device. The method includes the steps of: detecting an actual state of the device using a camera, preferably an AR device, which is preferably AR glasses; comparing the actual state of the device with a desired state of the device using a CPU connected to the camera; transmitting, on the basis of the comparison, a command for starting the function of the device or a function test, preferably a function test, from the CPU to the device; and activating the function or the function test of the device on the basis of this command.
