Analysis device

A piston head for a syringe pump comprises a barrier portion () for driving fluid through a syringe pump barrel (), wherein a peripheral section () of the barrier portion () is shaped to seal against the syringe pump barrel (); and a re-silent member () arranged to resist deformation of the shaped peripheral section () of the barrier portion ().

Piston seal

A pump for use in low-profile applications comprises a barrel for holding fluid; and a piston that converts a rotational driving force into a longitudinal driving motion within the barrel. The pump provides space saving advantages by reducing the need for external equipment and mechanisms around the pump for providing actuation or moving the actuating mechanism.

Pump

A one-way valve, comprises a valve housing; a valve member provided within the valve housing, the valve member being operative to open and close the valve and comprising a diaphragm with a central orifice to allow fluid to pass from one side of the diaphragm to the other; a valve inlet provided on a first side of the diaphragm; and a valve outlet provided on a second side of the diaphragm; wherein the configuration of the diaphragm and the valve housing biases the diaphragm to seal the inlet at rest.
