Abstract
A pumping system for infusing fluids into a patient. The pumping system includes a pump and a controller constructed to control operation of the pump. The controller has a hold condition in which it deactivates the pump. The controller also has a timer subsystem having a variable duration. A magnitude control operable by a human is connected to the controller, the magnitude control being constructed to alter the variable duration of the timer subsystem of the controller. The pumping system further includes an alarm connected to the controller, the controller constructed to activate the alarm upon expiration of the variable duration of the timer subsystem.
