This device has been constructed for use in testing a ventilator prior to use on a patient. With its anatomical design and two 'lungs' the device works to simulate the function of the ventilator on a human lung.

Made from high performance plastic and rubber silicone the device has been made to last and can be used again and again, and with its lightweight and compact design it is both easy to use and easy to store when not in use.

The device comes  with optional airway resistors to simulate the effects of the ventilator on a variety of lungs.
