Pump with programmable hold
First Claim
1. A pumping system for infusing fluids into a patient, said pumping system comprising:
- a pump;
a controller constructed to control operation of said pump, said controller having a hold condition in which said controller deactivates said pump, said controller further including a timer subsystem having a variable durationa magnitude control operable by a human, said magnitude control connected to said controller and constructed to alter said variable duration of said timer subsystem of said controller andan alarm connected to said controller, said controller constructed to activate said alarm upon expiration of said variable duration of said timer subsystem.

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.
