Title:
高精度投薬装置、システム及び方法
Document Type and Number:
Japanese Patent JP2005504384
Kind Code:
A
Abstract:
A liquid dispensing system increases the precision, reliability, and safety of dispensing medications and other liquids. An electronic brake grounds a power terminal of a pump motor to absorb the kinetic energy of the motor and other mechanically coupled components. The electronic brake reduces overage and overage variation in the dispensing of liquids at very little cost or complexity. A watchdog circuit monitors a controller heartbeat signal and disables the motor in the absence of a regular beat. The watchdog circuit along with redundant power switches greatly reduce the possibility of motor runaway in the event of component failure. A controller begins or ends each dispensing cycle with a diagnostic which determines whether the liquid dispensing system is fully operational. If not, the controller may disable the motor, emit an alarm tone, and display an alarm message.
