摘要:
In an embodiment, the invention relates to methods, apparatus, computer programs and computer program products for estimating a dry weight of a dialysis patient comprising the steps of determining a first fluid status of the patient between treatment sessions in a first stage, determining a second fluid status of the patient during treatment sessions in a second stage and estimating the dry weight based on the second fluid status.

An apparatus configured for carrying out CRRT on patients weighing up to about 20 kg incorporates a control unit having a blood pump and a plurality of fluid pumps mounted thereon, and a controller configured for operating the blood pump and fluid pumps, and an interactive operator control system including an operator interface screen operatively connected to the controller, the controller including software configured to operate the apparatus in response to operator input selections. The interactive operator control system includes operator inputs for setting patient weight, blood pump flow rate and fluid pump flow rates and the controller is configured to calculate and display maximum allowable fluid gain or loss based solely on patient weight settings between zero kg and about 20 kg and trigger warnings and alarms for selected or calculated levels of patient fluid gain or loss and stop operation of the pumps or termination of CRRT in response to patient fluid gain or loss in excess of the maximum.

An apparatus for extracorporeal blood treatment comprises a sensor (10) for emitting a signal indicating a variation in blood volume of an individual (7) subjected to extracorporeal blood treatment and a sensor (14) for emitting a signal indicating a weight loss of the individual. A control unit (20) receives the signals, compares the relation between the relative variation of blood volume (”BV%) and the relative variation of weight loss (”WL%) of the individual with a desired value, and controls the weight loss of the individual on the basis of the comparison. The apparatus enables automatically controlling a dialysis, preventing some complications due to hypotension.
摘要:
An apparatus for extracorporeal treatment of fluid and a process of setting up a medical apparatus for the delivery or collection of fluids are disclosed. According to the apparatus and the process, a control unit (10) is configured calculate set values of two or more of the fluid flow rates by imposing that an emptying time of containers of fresh fluid (16, 20, 21, 26) and/or a filling time of a waste container is substantially same as, or multiple of, the emptying time of one or more of the other containers of fresh fluid.

Eine Gewichtserfassungseinrichtung zur Ermittlung eines Patientengewichts für eine Dialysebehandlung beinhaltet eine Patientenwaage (4), die dazu angeordnet ist, einen Wiegevorgang durchzuführen und dadurch ein Ist-Gewicht eines sich auf der Waage befindenden Patienten zu erfassen, vorzugsweise einen Netzwerkanschluss, der dazu angeordnet ist, zumindest eine Information und/oder Daten betreffend die Ermittlung des Patientengewichts und/oder den Wiegevorgang erzeugende Komponente der Gewichtserfassungseinrichtung mit einem Datennetzwerk (2) zu verbinden, eine Ausgabeeinrichtung, die dazu angeordnet ist, das erfasste Ist-Gewicht des Patienten an der Patientenwaage (4) ablesbar und/oder in einem vorbestimmten Datenformat in das Datennetzwerk (2) auszugeben, zumindest eine Bildinformationsaufnahmeeinrichtung (4a, 6a), die ein Sichtfeld auf die Patientenwaage (4) zur visuellen Erfassung von Wiegevorgängen aufweist und dazu angeordnet ist, innerhalb des Sichtfelds einen Ablauf des Wiegevorgangs derart aufzuzeichnen, dass eine Ursache einer im Verlauf der Dialysetherapie auftretenden Änderung des Ist-Gewichts aus zumindest einer entsprechenden Aufzeichnung zumindest eines Wiegevorgangs ermittelbar ist. Ein vernetztes Dialysetherapiesystem beinhaltet eine solche Gewichtserfassungseinrichtung.
摘要:
A dialysis system (100, 100a, 100b, 100c, 100d) is described comprising a dialysis machine (10); and at least one of a patient weight sensor (WS) and a blood pressure sensor (BP) in wireless communication with the dialysis machine. The dialysis machine is a wireless slave to the at least one of the wireless master weight sensor and the blood pressure sensor such that the dialysis machine is discoverable by the at least one sensor when either the at least one sensor is powered.
摘要:
A multipurpose hemofiltration system (10) and method are disclosed for the removal of fluid and/or soluble waste from the blood of a patient. The system (10) continuously monitors the flow rates of drained fluid, blood, and infusate. When necessary, the pumping rates of the infusate, drained fluid and blood are adjusted to remove a preselected amount of fluid from the blood in a preselected time period. A supervisory controller (160) can monitor patient parameters, such as heart rate (120) and blood pressure (130), and adjust the pumping rates accordingly. The supervisory controller (160) uses fuzzy logic to make expert decisions, based upon a set of supervisory rules, to control each pumping rate to achieve a desired flow rate and to respond to fault conditions. An adaptive controller (162) corrects temporal variations in the flow rate based upon an adaptive law and a control law.
