Publication number: 20220280706Abstract: 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.Type: ApplicationFiled: May 23, 2022Publication date: September 8, 2022Applicant: DEKA Products Limited PartnershipInventors: Jason A.

Patent number: 8197439Abstract: A volume of fluid moved by a pump, such as a pump in an APD system, may be determined without direct measurement of the fluid, such as by flow meter, weight, etc. For example, a volume of a pump chamber (181) (having a movable element that varies the volume of the pump chamber) may be determined by measuring pressure in the pump chamber and a reference chamber, both while the two chambers are isolated from each other, and after the two chambers are fluidly connected so that pressures in the chambers may equalize. Equalization of the pressures may be assumed to occur in an adiabatic way, e.g., a mathematical model of the system that is based on an adiabatic pressure equalization process may be used to determine the pump chamber volume.Type: GrantFiled: January 23, 2009Date of Patent: June 12, 2012Assignee: DEKA Products Limited PartnershipInventors: Tien-Shoe Wang, David W.

Publication number: 20110092893Abstract: 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 cycler device (14) may include a heater bag receiving section (142) and a lid (143) mounted to cover and uncover the heater bag receiving section, potentially enabling faster heating of dialysate. A user interface (144) may be moveable to be received into the receiving section and covered by the Hd, if desired. The system may detect anomalous conditions, such as tilting of the system housing, 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 (30) 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.Type: ApplicationFiled: January 23, 2009Publication date: April 21, 2011Applicant: Deka Research & DevelopmentInventors: Jason A.
