1. An automated urinary output monitoring system for determining a urine output from a patient supported by a bed surface, comprising:
a urine collection assembly comprising:
a urinary catheter, a distal tip thereof configured to pass through an insertion site to be disposed inside the patient;
an interim collection container in fluid communication with the urinary catheter by way of a first drainage tube and configured to be placed adjacent the insertion site on the bed surface, the interim collection container defining a height from the bed surface that is less than 10% of a width or a length of the interim collection container to facilitate positioning a fluid surface disposed within the interim collection container below the insertion site, the interim collection container configured to prevent collapse when a crushing force is applied; and
a final collection container formed of a rigid material and fluidly coupled with the interim collection container via a second drainage tube;
a scale console comprising:
a frame configured to be coupled to a bed rail of the patient and defining a shelf to support a lower-most surface of the final collection container disposed thereon;
a scale disposed between the final collection container and the shelf and configured to determine a change in weight of the final collection container; and
one or more processors and non-transitory computer readable medium having logic stored thereon that, when executed by the one or more processors, performs scale operations including:
i) receiving weight data from the scale;
ii) determining a volume of urine collected within the final collection container; and
iii) wirelessly communicating the volume of urine to a system module; and
a pump configured to draw air from an outlet port disposed in a top-most surface of the final collection container and cause urine to flow from the interim collection container to the final collection container via the second drainage tube.
