Publication number: 20220409789Abstract: A medical treatment system is configured to output a predefined test pattern and to receive the signal by way of a microphone in order to test the volume and quality of the audio output in order to ensure the output audio signals effective to wake a sleeping patient. The failure of a processor to confirm the volume and fidelity of the audio output as well as the timeliness of the test pattern causes the processor to deny the resumption of a treatment and to generate an error signal.Type: ApplicationFiled: November 19, 2020Publication date: December 29, 2022Applicant: NxStage Medical, Inc.Inventors: Mark T.

Publication number: 20220313884Abstract: A system for preparing a medicament for use by a medicament user includes a proportioning machine with a controller and pumping and clamping actuators to engage a fluid circuit having pumping and clamping portions that engage with respective actuators of the proportioning machine. The fluid circuit includes a mixing container that is initially empty and later filled with two different concentrated medicaments from different concentrate containers and with purified water. The proportioning machine is configured to receive purified water and to mix it with the concentrated medicaments to produce a medicament and to output the medicament to a medicament consumer in such a way that to the medicament consumer the medicament appears to be provided from a bag of medicament. Custom mini batches of medicament may be produced by varying the amount of the concentrates and water.Type: ApplicationFiled: March 30, 2022Publication date: October 6, 2022Applicant: NxStage Medical, Inc.Inventors: Goetz FRIEDERICHS, Gregory YANTZ

The fluid circuit includes a mixing container that is initially empty and later filled with two different concentrated medicaments from different concentrate containers and with purified water. The circuit may include one or more pre-connected fluid quality sensors, such as conductivity sensors, in fluid communication with the mixing container. A single sterilizing filter is fluidly connected to two different medicament concentrates and the concentrates pass through the sterilizing filter. The sterilizing filter is tested to ensure its integrity. Little or no mixed fluid is lost during conductivity testing and custom mini batches of medicament may be produced by varying the amount of the concentrates and water.Type: ApplicationFiled: March 25, 2022Publication date: September 29, 2022Applicant: NxStage Medical, Inc.Inventors: Goetz FRIEDERICHS, Gregory YANTZ

Publication number: 20220126005Abstract: A proportioning device includes a proportioning machine with a temperature-compensating conductivity sensor, a controller, and pump actuator. A fluid circuit is engageable with the pump actuator, has connections for a source of water and one or more medicament concentrates, and includes a mixing container. The controller is configured to mix contents of the mixing container at a first time and to sample fluid from the mixing container, to pass the samples from the mixing container through the temperature-compensating conductivity sensor at different points in time as the fluid flows from the mixing container. The controller is further configured to mix contents of the mixing container a second time if the conductivities differ by a predefined magnitude.Type: ApplicationFiled: October 19, 2021Publication date: April 28, 2022Applicant: NxStage Medical, Inc.Inventors: Goetz FRIEDERICHS, Gregory YANTZ
