HSE Minivent (Type 845) Manual
These operating instructions describe the function and use of the mouse ventilator Type 845. The MiniVent mouse ventilator is a respirating pump for mouse ventilation. It operates at constant volume on the principle of the Starling pump. Unlike conventional Starling pumps the MiniVent works on the so-called nutating plunger principle in which the plunger movement determines the ventilation volume and in addition functions as the control valve. During each ventilating cycle the plunger simultaneously makes a displacement and a rotation. Suitably arranged bores and channels in plunger and cylinder operate inspiration and expiration through the plunger movement. The power supply for the pump is provided by a separate mains adapter (12V DC, 0.5A) which is supplied with it. The ventilation pump is intended for use in a laboratory environment in physiological and/or pharmacological research.
