28025 - Mouse Ventilator

Mouse Ventilator Mouse Ventilator

The 28025 Mouse Ventilator is a positive pressure pump (according to Starling's ventilation method), designed for the use with Mice, but also suitable for perinatal Rats and small birds. 

It consists of a variable-speed geared motor linked by a novel variable stroke mechanism to an interchangeable cylinder/piston assembly (1 or 0.5 ml).

The 28025drive consists of a variable speed geared motor linked by a novel variable stroke mechanism to easily interchangeable cylinder/piston assemblies. Their precisely regulated geared-motor, and the special materials of the ventilator kynematics provides the most accurate and reliable stroke rate control of any respirator available.

Motor speed is controlled by an electronic feedback-controlled drive, thus providing the most accurate and reliable stroke rate control of any respirator available. Electronic noise broadcasting is negligible, and the pumps are also quiet to the ear.

The 28025 can be equipped with 0.1 or 1ml cylinder/piston assembly. The back of the 28025 cabinet provides a flat surface where the operating table can be positioned, as close to the animal as possile, to minimize dead spaces. 

The operation of the ventilator may be "paused" by an external TTL logic signal (optional feature). Synchronised START/STOP feature available as optional (series 28125).

    Artificial ventilation, also called artificial respiration is any means of assisting or stimulating respiration in a subject which is not breathing or is not making sufficient respiratory effort on its own.

    Mechanical ventilation is a method to mechanically assist or replace spontaneous breathing: this involves a machine called a ventilator.
