Publication number: 20160228631Abstract: A system for controlling the position of a diaphragm in a diaphragm-containing pressure pod, is provided. The system can include a peristaltic pump, a pressure pod having a flow-through fluid side and a gas side that are separated by a diaphragm, and a pressure sensor operatively connected to the gas side. The pressure sensor is configured to sense pulses of pressure resulting from movement of the diaphragm and caused by the action of the peristaltic pump. A gas source and a valve can be in fluid communication with the gas side of the pressure pod and can be configured to provide gas to, or vent gas from, the gas side. A controller receives pressure signals from the pressure sensor and controls the valve in response, and in so doing, controls the position of the diaphragm. Methods for positioning the diaphragm are also included.Type: ApplicationFiled: November 25, 2014Publication date: August 11, 2016Applicant: FRESENIUS MEDICAL CARE HOLDINGS, INC.Inventors: Martin CRNKOVICH, Lee TANENBAUM, Michael Emmanuel KOTSOS, Fei WANG, Alex BROWN

Publication number: 20150008183Abstract: A dialysis machine useful in hemodialysis can process or treat a reverse osmosis water flow received through the machine to prepare a dialysate. The machine can include an additive source to introduce an additive, such as bicarbonate, to the reverse osmosis water flow. The machine can include a sensor in fluid communication with the additive introduction point that can measure the conductivity or similar characteristic of the solution. During a first time period when additive is actively introduced to the reverse omosis water flow, the sensor can measure a relatively high conductivity value. During a second time period when additive is not introduced to the reverse osmosis water flow, the sensor can measure a relatively low conductivity value. The dialysis machine can include a controller that processes these measurements to assist control and operation of the machine.Type: ApplicationFiled: July 2, 2013Publication date: January 8, 2015Inventors: Martin Crnkovich, Aiyuan Wang, Fei Wang

Patent number: 8632485Abstract: The invention provides apparatus and methods for home or other remote delivery of health care that gather subjective and objective measures of patient health and treatment, analyzing them (e.g., correlating them with one another and/or with norms) and reporting them to aid in on-going patient diagnosis and treatment (both on acute and chronic bases), as well as to aid physicians, nurses and other caregivers in decision support, monitoring treatment compliance, facilitating regulatory compliance, billing, and so forth. Thus, for example, in some aspects a health care delivery device comprising a medical treatment apparatus, such as a home hemodialysis or home peritoneal dialysis unit, that is coupled to a processor. The processor generates patient queries in connection with treatments rendered by the dialysis equipment (or other treatment apparatus).Type: GrantFiled: November 5, 2009Date of Patent: January 21, 2014Assignee: Fresenius Medical Care Holdings, Inc.Inventors: Christian Schlaeper, Martin Crnkovich, Jeffrey J.

Publication number: 20130211206Abstract: The invention provides a health care delivery system comprising a plurality of health care delivery devices (e.g., via the Internet, etc.), which can disposed in treatment centers ranging from patient homes to commercial health care facilities such as hospitals, dialysis centers and so forth. Reporting functionality can, instead of or in addition to identifying (and reporting on) discrepancies in the raw and/or analyzed data from the delivery devices, infer (and report) on possible causes of those discrepancies and, in some aspects of the invention, remedy those causes, thereby, providing automated operations support for the treatment centers.Type: ApplicationFiled: February 15, 2012Publication date: August 15, 2013Inventors: Jeffrey J. Sands, Josè Diaz-Buxo, Christian Schlaeper, Martin Crnkovich

Patent number: 7973667Abstract: The present invention relates to a wetness detector system that rapidly detects the presence of wetness due to a liquid leak in a system. The wetness detector system contains a reusable wetness sensor that is able to accurately detect the presence of wetness and, in the case of an extracorporeal blood treatment, the presence of blood. The wetness detector system can quickly alert both a user and medical personnel that a liquid leak has been detected in a treatment system and, if necessary, halt the removal of liquids and/or blood from the patient. If a liquid leak is not detected for a period of time, the wetness sensor can enter a low power state, extending the life of the device. The wetness detector system can monitor a number of wetness sensors simultaneously, which would, for example, eliminate the need for medical personnel to continuously inspect numerous patients visually for potentially fatal blood leaks due to needle dislodgement during an extracorporeal blood treatment.Type: GrantFiled: September 10, 2009Date of Patent: July 5, 2011Assignee: Fresenius Medical Care Holdings, Inc.Inventors: Martin Crnkovich, Peter Christensen, Roland Levin

Publication number: 20070106198Abstract: A chamber is described for use in an extracorporeal fluid system. The chamber has a bottom entry port and a bottom exit port. A microporous filter at the top of the chamber allows air in the fluid to vent from the chamber. In use, the chamber is filled with saline. Blood is then introduced into the chamber. A layer of saline is above a layer of blood in the chamber. The saline stagnates as the blood flows through the chamber. The saline keeps the blood from contacting the filter and depositing protein on the filter.Type: ApplicationFiled: October 21, 2005Publication date: May 10, 2007Inventors: Thomas Folden, Martin Crnkovich, Christian Schlaeper, Lynn Jensen, Mohsen Reihanifam
