A vapor sensor comprises a housing with an inlet opening in fluid communication with a sensor element within the housing. Standoff member(s) are positioned to maintain a gap between the inlet opening and a skin site. An operating circuit is in electrical communication with the sensor element and communicatively coupled to an output member. In use, the output member generates a sensory output indicative to an operator regarding concentration of alcoholic vapor in the ambient atmosphere proximate the skin site upon receiving communication from the operating circuit.

The present invention relates to apparatus and methods for storing moisture-sensitive products such as moisture-curable orthopedic splinting/casting product, in flexible, preferably elongated, pouches. The product is folded into a repeating series of discrete sections where each section has at least one segment that extend along the pouch length. By configuring the product in this way, it can be efficiently packaged, stored, and dispensed. Other embodiments of the invention include closure systems that permit sealing the pouch opening when product is not being dispensed and substantially sealing the pouch around the product during dispensing.
