A medical pump including an electromagnetic emitter and detector is provided. The emitter emits electromagnetic radiation of a predetermined wavelength. A pump set that is compatible with the medical pump modifies the emitted electromagnetic radiation when properly installed in the pump. The detector receives electromagnetic radiation, and a filter circuit excludes electromagnetic radiation having a wavelength other than the predetermined wavelength. The pump monitors the filtered signal to determine whether the received electromagnetic radiation corresponds to the emitted electromagnetic radiation as modified by a properly loaded, compatible pump set and determines whether a compatible pump set is properly loaded in the pump as a function thereof.

Pump set and pump with electromagnetic radiation operated interlock

An apparatus for selectively enabling power including a power supply, and a device having a controller and an input activated by a user. The controller is selectively powered by the power supply. While the device is in a sleep state, a sensing circuit senses activation of the input by the user and enables the power supply to provide power to the controller in response to the sensed activation of the input by the user. A latch circuit causes the power supply to continue to provide power to the controller. The controller is responsive to the sensed activation of the input by the user for enabling the latch circuit and for disabling the latch circuit, thereby reentering the device into a sleep state.

Ultra low power wake-up circuit

A medical pump including an electromagnetic emitter and detector is provided. The emitter emits electromagnetic radiation of a predetermined wavelength. A pump set that is compatible with the medical pump modifies the emitted electromagnetic radiation when properly installed in the pump. The detector receives electromagnetic radiation, and a filter excludes electromagnetic radiation having a wavelength other than the predetermined wavelength. The pump monitors the filtered signal to determine whether the received electromagnetic radiation corresponds to the emitted electromagnetic radiation as modified by a properly loaded, compatible pump set and determines whether a compatible pump set is properly loaded in the pump as a function thereof.
