摘要： A method of performing a dialysis treatment includes using a pump and a dialysate supply line to transport peritoneal dialysis fluid, the supply line having a proximal end into which peritoneal dialysis fluid is supplied and from which spend dialysate is withdrawn, and a distal end which is connected to a patient's peritoneal access. The method further includes generating proximal and distal pressure signals using pressure detectors located at both the proximal and distal ends, respectively, of said supply line. During a drain cycle in which spent dialysate is pumped from the patient, the method includes, responsively to the proximal and distal pressure signals, detecting a characteristic of a pressure difference between the distal and proximal ends whose magnitude is determined by a predicted change in dialysate properties, and responsively to the characteristic, generating a signal indicating the change in dialysate properties.

摘要： A peritoneal dialysis (“PD”) system having an air-aided pumping sequence is disclosed herein. In an example, a PD system includes a housing, a PD fluid pump housed by the housing, an airtrap, a fluid line extending from the airtrap, a fluid line valve positioned and arranged to operate with the fluid line, a gas line extending from an upper portion of the airtrap, and a gas line valve positioned and arranged to operate with the gas line. The system also includes a control unit configured to cause the fluid line valve to close, the gas line valve to open, and the PD fluid pump to pump gas from the airtrap into the gas line after a patient drain to create a pocket of gas in the fluid line and push residual used PD fluid towards a drain line.

摘要： In one aspect, a peritoneal dialysis (PD) system includes a housing that receives a disposable cassette, a plurality of pinch valves that receive respective sections of fluid tubing of the disposable cassette, an air port that forms an airtight seal with an air line of the disposable cassette, an air pump that alternatingly pushes air out of the air port and pulls air in from the air port, and a computer processor that controls the plurality of pinch valves and the air pump such that the cassette performs a dwell phase in which the diaphragm pump pumps fresh dialysate from a dialysate bag to a heater bag, a fill phase in which the diaphragm pump pumps the fresh dialysate from the heater bag to a patient line, and a drain phase in which the diaphragm pump pumps spent dialysate form the patient to a drain.

摘要： An apparatus peritoneal dialysis (1) comprising an automated peritoneal dialysis cycler (3) programmed to run a treatment session including a plurality of cycles, each cycle including a fill phase, a dwell phase and a drain phase of a peritoneal cavity of a patient (P), the treatment session lasting at most 720 min; the cycler (3) has a patient line (54) in communication with the patient (P), a source (S) of treatment fluid which includes an osmotic agent, a pump (5) to circulate the treatment fluid and a control system (74) configured to drive the cycler (3) to deliver the treatment session. The control system (74) is programmed to run a fill phase of a first cycle delivering a first treatment fluid to the patient, the first treatment fluid having a first concentration of the osmotic agent; subsequently to the first cycle, to run a fill phase of a second cycle delivering a second treatment fluid to the patient, the second treatment fluid having a second concentration of the osmotic agent different from the concentration of the first treatment fluid; subsequently to the second cycle, to run a fill phase of a third cycle delivering a third treatment fluid to the patient, the third treatment fluid having a third concentration of the osmotic agent different from the concentration of the second treatment fluid. The second concentration of the osmotic agent is lower than the first concentration of the osmotic agent and the third concentration of osmotic agent is higher than the second concentration of osmotic agent.

摘要： A disposable cassette and system for dialysis are disclosed. An example disposable cassette includes a rigid portion, a fluid source inlet configured to be placed in fluid communication with a fluid source, and a fluid pumping receptacle placed in fluid communication with the fluid source inlet. The fluid pumping receptacle is configured to operate with a fluid pump actuator to pump fluid from the fluid source. The example disposable cassette also includes a dampening chamber formed as part of the rigid portion and in fluid communication with the fluid pumping receptacle. The dampening chamber is sized and arranged to reduce pressure fluctuations in the fluid delivered from the fluid pumping receptacle. The example disposable cassette further includes an outlet in fluid communication with the dampening chamber. The outlet provides dialysis fluid for a dialysis treatment.
