Devices and methods for administering a medication in fluid form, the systems and methods including a basal flow path and a bolus flow path in parallel to the basal flow path. The bolus flow path includes a combined piston pump and rotatable valve. The piston pump is configured to prevent partial dosing of a bolus dose.

An example breath collection and sampling device disclosed herein comprises a cartridge housing having a breath capture module, and a rotary valve operatively coupling a mouthpiece with the breath capture module. The rotary valve can have an open position where breath of a user can pass through the rotary valve, across capture sites of the breath capture module, and into a vacuum port, and a closed position for sealing the breath capture module from fluid passing through the rotary valve, while allowing the breath capture module to be exposed to a reagent for subsequent analysis of contents within the captured breath.

Systems and techniques for detecting a target substance, such as THC, in a breath constituent sample are provided.

An apparatus for tissue ablation using radiofrequency energy comprises a housing extending from a first end to a second end. One or more pipes extend from the first end and each of the one or more pipes terminates at a tip. Each tip includes a light source operable to provide light. The apparatus further comprises a probe extending from some of the one or more pipes. Each probe is operable to deliver RF energy and to extend from or retract into the tip.

Devices and methods for administering a medication in fluid form, the systems and methods including a basal flow path and a bolus flow path in parallel to the basal flow path. The bolus flow path includes an inlet check valve, a first outlet check valve downstream of the inlet check valve, and a piston pump disposed between the inlet check valve and the first outlet check valve. The piston pump is configured to prevent partial dosing of a bolus dose.

Chemical compositions and methods provide labeling, detection and measurement of target substances in exhaled human breath, and can be implemented in connection with a handheld device&#x2014;much like a Breathalyzer portable breath testing unit for alcohol&#x2014;to support rapid quantification of levels of cannabinoid compounds, such as tetrahydrocannabinol (THC), of suspected users at the roadside.

An x-ray collimator can be constructed from multiple subassemblies, which at least includes a first subassembly that reduces the leakage of x-ray radiation between adjacent apertures and a second subassembly that reduces the spill of x-ray radiation around the detector face. Each of these subassemblies has numerous apertures. In the first subassembly these apertures correspond to focal spots on an x-ray source, and in the second subassembly, these apertures are shaped such that the dimensions increase from smaller entrances to larger exits.
