Abstract
Systems, methods and devices are disclosed for monitoring sobriety using a hand-held breath testing device. The hand-held breath testing device comprises a sample pump which utilizes a bellows assembly to draw an air sample through an inlet port and into the sample pump. The sample pump comprises a bi-stable spring and nitinol-based structures which cause the pump to actuate and allow the bellows to expand and compress. The sample pump can be utilized with other sampling devices, including but not limited to medical devices, wherein a sampling of a measured volume of gas is desired.
