The purpose of this study was to evaluate the effect of carrier particle size and simulated inspiratory flow increase rate on emptying from dry powder inhalers (DPIs). Several flow rate ramps were created using a computer-generated voltage signal linked to an electronic proportioning valve with a fast response time. Different linear ramps were programmed to(More)
Engine vibrations have been one of the major problems for the engine manufacturers in the world. The engine excitation forces, arising from the gas pressure and unbalance forces are the sources of vibrations.Anti Vibration Mounts(AVMs) are the structures used to absorb the vibrations and dampen the harm causing forces. Mount result in a system which is(More)
Metered-dose inhalers (MDIs) are an effective means of generating drug-containing aerosols targeted for delivery to intrapulmonary airways. Many problems associated with incorrect patient use of MDIs are mitigated by adding a valved spacer device to the inhaler mouthpiece. This in vitro study compared the efficiency of drug output through a new spacer(More)
