摘要:
A peritoneal dialysis system includes a control unit configured to (i) store a sleep state pattern for the patient, (ii) begin a patient drain followed by a patient fill when at least one sensor indicates that the patient is in a deep sleep state, (iii) extend a dwell period if the sleep state pattern indicates that the patient will enter a subsequent deep sleep state within a first time duration after a programmed dwell period, and (iv) shorten the dwell period if the sleep state pattern indicates that the patient will leave the deep sleep state within a second time duration after an end of the programmed dwell period. The system alternatively or additionally assesses or records a stress level of and/or a fluid/caloric intake by the patient and takes actions accordingly.

A mobile dialysis therapy cart includes a top shelf; a cycler compartment positioned below the top shelf, the cycler compartment sized and shaped to house an APD cycler; a fluid bag management compartment sized and shaped to house at least two fluid bags; a drain compartment positioned below the fluid bag management compartment; and a plurality of wheels. The cart may include a heating device associated with the fluid bag management compartment and/or a sanitizing light source for sanitizing a location of a disposable set associated with the fluid bags.

An airtrap for a medical or physiological fluid in one embodiment includes a conical housing having a radius that increases from its top to its bottom when the housing is positioned for operation; a medical or physiological fluid inlet located at an upper portion of the conical housing; a medical or physiological fluid outlet located at a lower portion of the conical housing, the inlet and the outlet positioned and arranged so that medical or physiological fluid spirals in an increasing arc around an inside of the conical housing downwardly from the inlet to the outlet; and a gas collection area located at an upper portion of the conical housing. In another embodiment, the airtrap is shaped like a seahorse having a head section and a tail section. Any of the airtraps herein may be used for example in blood sets, peritoneal dialysis cassette tubing, and drug delivery sets.

Processing systems and methods comprise a separation device that, in use, performs a separation process including separation of red blood cells from blood or a suspension containing red blood cells. The systems and methods include an outlet line (104) coupled to the separation device to remove red blood cells from the separation device, at least in part, while the separation process occurs. A sensor (148) associated with the outlet line (104) senses hematocrit of red blood cells removed from the separation device and generates a sensed hematocrit output. A controller is coupled to the separation device to control removal of red blood cells from the separation device based, at least in part, upon the sensed hematocrit.

A renal treatment fluid priming method includes priming an extracorporeal circuit (30) connected to a patient with a physiologically compatible fluid, the extracorporeal circuit including an arterial line, a venous line and blood compartment of a blood filter (34); and pumping from a renal treatment fluid line in communication with the blood filter (i) pulling blood from the patient through the arterial line to flush the physiologically compatible fluid through the arterial line and the blood filter compartment into the renal treatment fluid line and (ii) pulling blood from the patient through the venous line to flush the physiologically compatible fluid through the venous line and the blood filter compartment into the renal treatment fluid line, such that a greater volume of blood is pulled from the patient via (i) and (ii) than a volume of the extracorporeal circuit.

A dialysis system includes a dialyzer (34); a blood pump (18c) coupled operably to a dialyzer; a dialysate inlet pump (18a) coupled operably to a dialysate inlet of the dialyzer; a dialysate outlet pump (18b) coupled operably to a dialysate outlet of the dialyzer; a first non-invasive fluid velocity sensor (40a) positioned to sensor of inlet flowrate of dialysate pumped to the dialysate inlet by the dialysate inlet pump; and a second non-invasive fluid velocity sensor (40b) positioned to sense an outlet flowrate of dialysate pumped from the dialysate outlet by the dialysate outlet pump.
摘要:
A medical fluid system includes a medical fluid pump; a container holding a fluid to be pumped by the medical fluid pump, the fluid at a first time having a first conductivity, the fluid at a second time having a second conductivity; and a radio frequency level sensor positioned in operable relation with the container, the radio frequency operation of the level sensor configured so as to be (i) indicative of a level of the fluid in the container and (ii) at least substantially independent of whether the fluid has the first conductivity or the second conductivity. The medical fluid system can determine the level of medical fluid by measuring the resistance, impedance or phase shift seen by the sensor.

An optical sensing assembly (46) is adapted for use in association with a separation device having a separation zone associated with umbilicus (100) in which red blood cells and plasma are separated from blood. The assembly (46) comprises a controllercommunicating with and having different, selectable functions for operating first optical sensing unit (506A, 508A) associated with a red blood cell outlet path (104) that removes red blood cells. The controller also communicates with a second optical sensing unit (506B, 508B) associated with a plasma outlet path (106) for removing plasma.
