CPC A61G 7/05769 (2013.01) [A61G 7/05707 (2013.01); A61F 2007/006 (2013.01); A61F 2007/0063 (2013.01); A61G 2203/34 (2013.01)] | 10 Claims |
1. Dynamic support apparatus comprising:
an actuator defining a volume configured to receive fluid;
a pump;
a manifold in fluid communication with said pump comprising:
a fluid flow path;
a flow path valve associated with said fluid flow path; and
a manifold port for said actuator;
a pressure sensor configured to monitor pressure at said manifold port and generate a pressure data signal; and
a processor configured to:
generate a pump command to which said pump is responsive;
generate a manifold command that governs a position of said valve wherein fluid communication is established between said pump and said manifold port;
monitor the pressure data signal;
collect a pressure data sample from the pressure sensor after a wait period has elapsed; and
determine if a pressure at said manifold port is above a first pressure; if so, then:
generate a deflation command that governs the position wherein said manifold port is in fluid communication with an atmosphere;
monitor the pressure data signal while said manifold port is in communication with the atmosphere to determine if the pressure is within a range of a second pressure; and
collect a vented pressure data sample after generation of the deflation command and compare the vented pressure data sample to a sum of a target pressure and a dead band pressure range, less an additional margin.
