Abstract: A wasting station for receiving a wasted medication from a medication dispenser is provided. The wasting station includes a base and a locking mechanism. The base includes a weight sensor to measure a weight of a waste container supported by the base. The wasting station can determine, based on the measured weight, a volume of the wasted medication positioned within the waste container. The locking mechanism includes a first end coupled to the base. The locking mechanism also includes a second end coupled to the waste container when the locking mechanism is in a first position and decoupled from the waste container when the locking mechanism moves from the first position to a second position, thereby allowing for removal of the waste container.

Abstract: The present invention pertains to an apparatus for determining cardiac performance in a patient. The apparatus comprises a conductance catheter which can be excited with multiple frequencies for measuring instantaneous volume of a heart chamber. The apparatus comprises a mechanism for measuring instantaneous pressure of the heart chamber. The apparatus comprises a mechanism for processing the instantaneous volume and the pressure of the heart chamber to identify mechanical strength of the chamber and for automatically producing a plurality of desired waveforms at desired frequencies for the conductance catheter. The processing mechanism is connected to the pressure measuring mechanism and the volume measuring mechanism. The present invention pertains to a method for determining cardiac performance in a patient. The method comprises the steps of applying automatically multifrequencies to a conductance catheter. Then there is the step of measuring the instantaneous volume of a heart chamber of the patient.
