Abstract
Provided herein is a device for measuring puff topography generated by a human user of a smoking device and methods for using the same. The device may be used for research on puffing behavior of tobacco product users in both clinical and non-clinical settings.
Claims6
A puff topography apparatus for providing puff topographical information, comprising:
- a holder comprising a flow sleeve wherein an electronic smoking device is received, wherein the holder has a tubular structure of a size suitable for said electronic smoking device and wherein each end of said electronic smoking device extends beyond said holder;
- a means for applying a seal around said electronic smoking device at each end of said tubular structure;
- an air inlet to permit air intake into said tubular structure;
- a flow sensor for measurement of air flow into said tubular structure;
- a means for data acquisition;
- and
- a power supply.
4 more elements
A method for measuring puff topography of a subject smoking an electronic smoking device, comprising the steps of:
- placing said electronic smoking device within a holder comprising a flow sleeve operably connected to an air inlet and a flow sensor, wherein each end of said electronic smoking device extends beyond said holder;
- sealing the ends of said flow sleeve around said electronic smoking device, wherein airflow is channeled through a single inlet;
- providing said electronic smoking device arranged in said holder to said subject for smoking;
- measuring flow rate of air entering said air inlet and passing through said electronic smoking device for each puff performed during said smoking step;
- and
- acquiring and analyzing flow rate associated with at least one puff performed in said smoking step.
