The
Harvard Apparatus Starling 'Ideal' ventilator features negligible
dead space, low noise, low wear and high reliability. The
rate is indicated on a LED display or alternatively at the
press of a button the stroke/volume may be displayed.
Both
the rate and stroke can be changed whilst the ventilator is
running. The fine pitch of the stroke control allows the stroke
to be accurately set and the actual stroke is clearly displayed
on a static pointer scale, not on the side of the piston,
or moving scale.
The
ventilator has been recently revised and now features a comprehensive
alarm system as standard. In the event of a power failure
or a mechanical failure the alarm will sound for several minutes
and also provide a visual indication.
Three
different sizes are available: 0.25 to 2.5 ml, 1.0 to 10 ml
and 3.0 to 30 ml. All air drawn into the pump is expelled
on each stroke. The negligible dead space feature ensures
that the piston reaches the end of the cylinder at the top
of every stroke.
The
speed of the motor is continuously monitored and regulated
to maintain a constant stroke rate. The precision-machined
valve assembly has four ports which provide maximum air channelling
flexibility. The input may be room air or non-explosive gas
mixtures. The exhaust air can be partially or completely recycled,
or collected for analysis.
