Compact and reliable Mouse Ventilator

BIO-28025 Mouse Ventilator is a mechanically unique positive pressure pump, according to Starling’s ventilation method, designed for use with mice, but also suitable for very small birds, perinatal rats, etc., which features:

    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.
