A urine analysis device for bed side monitoring of a patient, comprising:

a drip chamber having an inlet in fluid communication with a urine collecting tube for receiving urine from a patient;
a rotating mechanical assembly adapted to periodically turn a plurality of measuring members within the drip chamber below the inlet such that falling drops, generated from the urine received from the patient and falling from said inlet along said drip chamber are intercepted by said rotating mechanical assembly, bringing into contact a respective one of the plurality of measuring members positioned under said inlet with said falling drops, wherein the plurality of measuring members are sequentially placed in a drop zone of said falling drops, by said rotating;
wherein each of the plurality of measuring members provides at least one of an indication of presence and a measurement of concentration of a different urine constituent in the urine.

A method of operating a urine analysis device for bed side monitoring of a patient, comprising:

providing a drip chamber having an inlet in fluid communication with a urine collecting tube for receiving urine from a patient;
and
instructing a rotating mechanical assembly to periodically turn a plurality of measuring members within the drip chamber below the inlet such that falling drops, generated from the urine received from the patient and falling from said inlet along said drip chamber are intercepted by said rotating mechanical assembly, bringing into contact a respective one of the plurality of measuring members positioned under said inlet with said falling drops, wherein the plurality of measuring members are sequentially placed in a drop zone of said falling drops, by said rotating;
wherein each of the plurality of measuring members provides at least one of an indication of presence and a measurement of concentration of a different urine constituent in the urine at each event of a multiple sequential events.
