Telemetry recording system for measuring of gastrointestinal contractile activity in unrestrained animal(macaques,dogs)

Measuring of gastrointestinal contractile activity is easily influenced by the measurement condition such as anesthesia and stress.
Therefore, measurement should be performed in conscious and unrestrained state. Gastrointestinal contractile activity in conscious and unrestrained animal (macaques, dogs) can be observed in real time and the effects of drugs can be evaluated by force transducers installed on gastrointestinal tract and analysis equipment receiving the signal of gastrointestinal contractile activity.
Several transducers installed on several parts of tract make it possible to measure different gastrointestinal contractile activity simultaneously.
