Description
DESCRIPTION:
This transducer is designed to perform the bronchospasm test on the guinea pig. The Transducer is also a useful research tool for screening substances inducing the opposite effect, both those causing active bronchodilation in basal conditions and those with antagonize test drugs such as histamine, bradykinin etc.
SECTORS OF USE:
Student and chemical research laboratories
MAIN FEATURES:
The whole device is a compact unit made entirely of Perspex, mounted on a base along with its own power supply and controls. The system operates as follows. When aerodynamic alterations take place in the bronchi, inspiration pressure pulses acting on the water in column C change their intensity and air is exhausted through nozzle N into the atmosphere at differing rates via the air flow meter. The unit enables the research worker to evaluate the spasm inducing effect of drugs having a very wide range of action, not necessarily intended to act on respiratory dynamics. When bronchodilations are administered, pressure pulses are reduced to below normal breathing values. When bronchoconstrictions are administered and bronchospasm occurs, an actual quantity of air delivered by the pump and not accepted by the lungs, finds its way out via the by-pass connection.
