ENTERAL FEEDING PUMP MOTOR UNIT AND METHOD OF USE

摘要

An enteral feeding pump motor unit (10) and method of use are disclosed. The motor unit (10) uses optical sensors (54) to monitor the rotational period and position of a platen (22) of the motor unit (10). If the rotational period is different from a predetermined desired period, a controller in communication with the optical sensors (54) and the platen (22) changes the rate at which the platen rotates so as to effectuate movement of a desired amount of fluid through a delivery set passing through the motor unit (10). In accordance with one aspect of the invention, the optical sensors (54) are disposed in an asymmetrical pattern to enable self-testing and to avoid ambiguous readings.
