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.
Claims20
A sample pump comprising:
- an inlet port configured to draw an air sample into the sample pump;
- a bellows assembly configured to expand and compress;
- a trigger assembly comprising a wire trigger structure and a bi-stable trigger spring, wherein the trigger structure is configured to transform into a predetermined shape in response to a first current being applied to the trigger structure, wherein the trigger structure, upon transforming into its predetermined shape, is configured to exert a force on the bi-stable trigger spring and cause the bellows assembly to expand;
- and
- a retraction assembly comprising a first wire element and a second wire element, wherein the first wire element and the second wire element are composed of a first shape memory alloy, wherein the first wire element and the second wire element are configured to compress in response to a second current and cause the bellows assembly to compress.
