Claim Text:
1. A disc pump system comprising: a pump body having a substantially cylindrical shape defining a cavity for containing a fluid, the cavity being formed by a side wall closed at both ends by substantially circular end walls, at least one of the end walls being a driven end wall having a central portion and a peripheral portion extending radially outwardly from the central portion of the driven end wall; an actuator operatively associated with the central portion of the driven end wall to cause an oscillatory motion of the driven end wall thereby generating displacement oscillations of the driven end wall in a direction substantially perpendicular thereto with an annular node between the center of the driven end wall and the side wall when in use; an isolator operatively associated with the peripheral portion of the driven end wall to reduce damping of the displacement oscillations, the isolator comprising a flexible printed circuit material; an electrochemical detection system coupled to conductive paths in the isolator, the electrochemical detection system being operable to detect the presence of a target gas in fluid that flows through the pump body; a first aperture disposed at any location in either one of the end walls other than at the annular node and extending through the pump body; a second aperture disposed at any location in the pump body other than the location of the first aperture and extending through the pump body; and, a valve disposed in at least one of the first aperture and second aperture; whereby:
