The WRD unit controls a pump/manifold assembly used to regulate
pressure of four individual sections in a patented air mattress
system. The system gently rolls a bedridden patient to the right
or left through a 60-degree arc to alter their position in order
to prevent and/or treat pressure ulcers. Programmable dwell time
for any given position ranges from one minute up to two hours.
Excellent cost-to-performance ratio
Manufacturer used prototype with RS-232 interface
to monitor, in real time, mattress PSI and establish
proper roll angles based on patient weights
Controls and monitors programmable PSI in each mattress section
Three dedicated and one custom operating mode
Reads two pressure sensors and controls pressure to +/-.01 0
PSI using standard pneumatic pump and
valves RS-232 interface to remote computer
Backlighted LCD display and front panel switches allow operator
to select or program a patient's specific roll
Mattress sensor interface is designed using 'smart sensor"
technology; all mattresses and controls are
Internal self-diagnostics aid in troubleshooting mattress systems
in the field FDA, UL, and CSA approved
