Abstract: A fluid treatment plant has a filter module including at least a first filter and a second filter connected in series and connectable to a supply of fluid. A pump is fluidly connected to the filter module and a controller with a fluid quality sensor is connected to detect a quality of the fluid between the first filter and the second filter. A filter module detector is connected to the controller configured to uniquely detect a filter module connected to the pump, and the controller is controls the pump responsively to a signal from the fluid quality sensor and the module detector. The controller is configured to continue pumping based on output of the quality sensor and/or based on output from the filter module detector.

Abstract: A needle assembly withdraws medicine from a vial having a rubber septum and injects the medicine into a port in a patient while not endangering the caregiver with an accidental stick with a contaminated used needle. The needle assembly includes a sharp hollow needle for penetrating a septum of a vial and a blunt cannula for injecting into an injection port. The needle can be of any type including intramuscular. The blunt cannula concentrically surrounding the sharp hollow needle, forms a liquid-tight seal with the sharp hollow needle, and extends relative to the sharp hollow needle in a locked position.

Abstract: An apparatus for safely removing a needle from a subcutaneous septum, comprising a pair of blades, each having corresponding first and second ends, pivotally jointed together at their first ends whereby the blades are pivotal between a closed position in which the blades are substantially overlapped and an open position in which the second ends of the blades are spaced apart; and a concave groove in an edge of each blade at the second ends thereof positioned such that each groove is directly opposite the other in a mirrored relationship when the blades are in the open position.
