摘要：
A patient-controlled switch-operated drug delivery device, comprising: a device switch (102, 302) configured to be operated by a user, which provides a switch signal to a switch input of a device controller (104 , 300) when operated by a user； having the device controller, said switch input (308) operatively connected to the switch, and configured to receive the switch signal from the switch, the device controller being configured to operate the device when the user activates the switch at least twice inside of a predetermined period of time and separated by a period of rebound suppression； and a switch integrity check subcircuit, which is configured to detect a fault or a precursor of a breaker failure, whereby the controller executes a switch failure subroutine when a fault is detected or a precursor to a fault ； in which the device controller is configured to check the switch integrity using the switch integrity check subcircuit during the period of rebound suppression between button presses establishing circuit parameters and testing voltages or changes in voltage and comparing them with the default values indicative of a normally functioning circuit.Un dispositivo de administración de fármacos controlado por paciente operado por interruptor, que comprende: un interruptor de dispositivo (102, 302) configurado para operarse por un usuario, que proporciona una señal de interruptor a una entrada de interruptor de un controlador de dispositivo (104, 300) cuando se opera por un usuario； teniendo el controlador de dispositivo, dicha entrada de interruptor (308) conectada operativamente al interruptor, y configurada para recibir la señal de interruptor del interruptor, estando el controlador de dispositivo configurado para accionar el dispositivo cuando el usuario activa el interruptor al menos dos veces dentro de un período predeterminado de tiempo y separado por un período de supresión de rebotes； y un subcircuito de comprobación de integridad de interruptor, que est
