Pneumex is the original developer of Pneumatic Unweighting. The first PneuWeight was built for the
Seattle Supersonics 25 years ago
Because of the
design of analog gauges we can pick a gauge from a 0 to 30 psi up to a 0 to 150
psi to monitor our system. Each has its own good points.
0 to 30
psi gauge would monitor up to 60 pounds but would only be accurate and easy to
read in the under 60 pound range.
0 to 100
psi gauge would monitor up to 200 pounds. It is accurate and easy to read
up to 200 pounds.
0 to 150
psi gauge would let us monitor up to 300 pounds but is much less precise and
harder to read in any range.
The gauge we have chosen to use for
unweighting was selected to be user friendly.
The range of weight that is normally taken off the average individual is
one third to one half their body weight, approximately 40 – 150 pounds. We therefore want to monitor this range with
the highest degree of accuracy
That being said the PneuWeight™ is still
capable of lifting 300 pounds and safety tested to 1200 pounds. The 0-100 psi gauge lets us monitor up to 200
pounds, still allowing us more than the 200 unmonitored to help lift a patient
upright. Once the patient is on their
feet and we have the lift we are looking for, the monitor is dialed back to the
desired weight bearing load, significantly under 200 pounds.
