Fluid line occlusion detection system and methods


The systems, methods and articles described herein are directed to at least one pressure sensor along a downstream fluid line which senses fluid pressure and assists an occlusion detection feature in determining the presence of occlusions in the downstream fluid line. In addition, the system can dynamically adapt the occlusion detection feature based on a delivery of fluid, such as a bolus, in order to prevent the system from creating a false alarm regarding an occlusion of the downstream fluid line..

Mattress, pressure sensor calibration method, and bed device


When pressure detected by a pressure sensor connected to a calibration standard cell has continuously fallen within a regulated pressure range at calibration for a regulated duration at calibration, zero-adjustment is performed based on the pressure value detected by the pressure sensor. Then, communication between the plurality of cells is created to perform internal pressure adjustment of the plurality of cells to a predetermined internal pressure value, based on the pressure value detected by the pressure sensor connected to the calibration standard cell and calibrate each of pressure sensors connecting to the plurality of cells, based on the adjusted internal pressure.
