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.

Peritoneal dialysis system having air-aided pumping sequences

A peritoneal dialysis ('PD') system includes a housing; a dialysis fluid pump housed by the housing; a dual lumen patient line extending from the housing; a filter set including a final stage filter located along a first line, and which includes a second line in parallel with the first line, the first line in fluid communication with a first lumen of the dual lumen patient line, and the second line in fluid communication with a second lumen of the dual lumen patient line; a pressure sensor located within the housing and positioned so as to sense a static or substantially static PD fluid pressure in the second lumen while fresh PD fluid is pumped through the first lumen and the final stage filter; and a control unit configured to use the sensed static or substantially static pressure in a pressure control routine for the dialysis fluid pump.

Peritoneal dialysis system and method having intraperitoneal pressure sensing

A peritoneal dialysis system includes a housing; a dialysis fluid pump housed by the housing; a patient line extendable from the housing; and a hose reel located within the housing, the hose reel configured to coil the patient line when disconnected from a patient. The patient line may be a dual lumen patient line, wherein the dual lumen patient line is coiled about the hose reel during a disinfection sequence for disinfecting the dual lumen patient line and the dialysis fluid pump.

Peritoneal dialysis system having disinfection fluid pumping and pathway

Systems and methods for monitoring the presence of blood in an extracorporeal blood circuit are disclosed. A control unit, which is connected to a blood detector and to one or several pressure sensors, determines whether blood is present in the membrane device based on the differential pressure there over and generates a signal if the presence of blood as detected by the blood detector and the presence of blood as determined based on the differential pressure value do not coincide with each other.

Apparatus for extracorporeal blood treatment and method of operation

A machine () for extracorporeal blood treatment comprises a device () for ultrafiltration of a liquid through a semi-permeable membrane () of a blood treatment device (), a first sensor () for ultrafiltration rate through the membrane, a second group of sensors () for measuring a trans-membrane pressure, an infusion line () with an infusion pump () and a programmed controller () for calculating a maximum infusion rate as a function of the transmembrane pressure. The machine is suitable for kidney failure treatments, such as hemofiltration and hemodiafiltration. In a relatively short time the machine enables a large quantity of corporeal blood to be removed from the patient.

Methods and apparatus are disclosed for testing differential pressure sensors. The method includes applying a pressure of predetermined value to the reference side of the differntial pressure sensors, measuring the output values from the measurement sides of the differential pressure sensors, and comparing the measured output values. The disclosed apparatus includes a pump for simultaneously applying a pressure of a predetermined value to the reference side of a number of differential pressure sensors.

Method and apparatus for checking sensors

Methods and apparatus are disclosed for monitoring an infusion pump utilized in a dialysis machine for hemodiafiltration or hemofiltration. The apparatus includes a first flow circuit for a dialysis solution, including a flow meter, a second flow circuit for blood, the dialysis apparatus including a first chamber connected to the first flow circuit, a second chamber connected to the second flow circuit, and a semipermeable membrane separating the first and second chambers, a third flow circuit for withdrawing an infusion solution from the first flow circuit and delivering the infusion solution to the second flow circuit, the third flow circuit including the infusion pump, and a first valve for disconnecting the dialysis apparatus from the first flow circuit and connecting the infusion pump in series with the flow meter in the first flow circuit whereby the expected flow through the infusion pump can be compared with the measured flow through the flow meter.
