a) The tidal volume, in the range 0.1 - 1 ml (or 0.05 -
0.5 when the smaller cylinder/piston is installed)
can be selected via its knob either while the pump
is running or at a standstill. The stroke volume
scale is ample and provided with precise engraved
marks.
b) The rate, selected by a knob is indicated by a 3-digit
solid state display, in the range 60- 300
strokes per minute.
c) Suitable channels and ports, machined in the
mobile and stationary plates of the oscillating
cylinder set- up, provide the switching of the air
flow, with practically no dead space.
d) A unique variable stroke linkage mechanism, very
similar in principle to the one embodied in the well
known Ventilators 7025 and 6025 of our make,
operates the piston.
The reciprocating motion is adjusted and
transmitted to the piston by rods and articulated
joints only, which leads to minimal wear, no
backlash, silent operation and exact stroke
reproducibility.
The instrument is compact and light, 20x13x18.5 cm
and 2.5 Kg, see picture, and it is self- contained: in
other words, it embodies its power supply which feeds
the geared motor, its feedback controller and the rate
display.
START/STOP MODEL
For electrophysiological recording, X- ray and imaging,
it is beneficial if not essential to minimize any
extraneous movement of the anesthetized animal during
a procedure.
A Mouse Ventilator version is available, Cat. 28125, in
which a START/STOP function is embodied in the
circuit. This function gives the operator a means to stop
and restart the respi rator at “full lungs” point, via an
external trigger pulse.
