Characterization and/or detection of structural characteristics associated with syringes and/or automatic injection devices based on acoustics

摘要

Disclosed is a system (1) for characterising a syringe (5) based on structural characteristics of the syringe (5). The system (1) comprises a transducer (3), a receiver (4) and a syringe characterization unit (6). The transducer (3) is configured to vibrate at one or more frequencies. The receiver (4) detects a syringe response to vibrations of the transducer (3). The syringe characterisation unit (6) is configured to characterise the response detected by the receiver (4). At least one of the transducer (3) or the receiver (4) is configured to physically contact the syringe (5).
