Abstract: An access disconnection system includes an extracorporeal circuit; first and second contacts provided in the extracorporeal circuit; a current source communicating with the first contact and configured to generate a current within fluid flowing through the extracorporeal circuit; and an apparatus positioned to apply a signal at multiple points along a path from the extracorporeal circuit, the signals tending to prevent at least a portion of the current from traveling through a ground path in parallel to the extracorporeal circuit.

Abstract: An apparatus for detecting dislodgement of a needle inserted into a patient includes a sensor for detecting wetness due to blood and a sensor holder to secure the sensor to the patient such that the sensor detects wetness due to blood loss from the patient upon dislodgement of the needle. Methods and apparatuses for detecting, monitoring and/or controlling blood loss from a patient due to needle dislodgement are also provided.

Abstract: A flow rate measurement system and method suitable for monitoring filtrate flow in a hemodialysis apparatus, provides a pair of flow meters (12,14) in series at the input of a dialyzer (10) for producing electrical signals indicative of dialysate flow rate and a pair of flow meters (16, 18) in series at the output of the dialyzer (10) for producing electrical signals indicative of dialysate plus filtrate flow rate. A computer (30) receives the flow rate signals and is programmed to calibrate each flow meter during a calibration phase to correct for any variations in each pair to thereby produce corrective scale factors. During an operational phase of the apparatus, the program monitors the flow meters and provides an alarm if any changes between the readings of either of the pairs of flow meters (12,14/16,18) occurs.

Abstract: Un sistema de desconexión de acceso que comprende: un circuito (35) extracorpóreo; unos contactos (24, 22) arterial y venoso proporcionados en el circuito (35) extracorpóreo; unos aparatos (36) de acceso del paciente arterial y venoso; una fuente (160) de señales que comunica con al menos uno de los contactos (24, 22) arterial y venoso y configurada para generar una señal dentro de un fluido que fluye a través del circuito (35) extracorpóreo; y un aparato de detección (254) configurado para detectar una primera parte de la señal indicativa de una primera impedancia (RDA, RDV) producida por un fluido que fluye a través de una primera parte del circuito (35) extracorpóreo; en el que al menos uno de los contactos (24, 22) arterial y venoso está colocado suficientemente cerca de un aparato (36) de acceso del paciente arterial y venoso respectivo de tal manera que una segunda parte de la señal indicativa de una segunda impedancia (RUV) producida por un fluido que fluye a través de una segunda parte del circuito (35) extracorpóreo aumenta en relación con la primera impedancia (RDA, RDV) hasta el punto de que pueden ignorarse los efectos de un circuito cerrado de tierra paralelo (250).

Abstract: An improved conductivity based servo-proportioning system for hemodialysis machines. The servo-proportioning system calculates the actual conductivity contributions of the individual chemical components of the concentrate being utilized, to determine the conductivity set points. If an Acidified and Bicarb operation is being performed, then the servo-proportioning system calculates a conductivity set point at both an intermediate and final stage of the servo-proportioning system. If only acetate is being performed, then only the acetate individual chemical components are calculated. If the Na and/or Bicarb concentrations are to be varied, then the conductivity is calculated for the changed Na and/or Bicarb concentrations.
