1. A hemodialysis system, comprising:
- a blood circuit tube having an interior;
a dialyzer in fluid communication with the interior of the blood circuit tube; and
not more than one substantially biochemically inert disposable sensor unit including at least one disposable sensor device in fluid communication with the interior of the blood circuit tube, wherein the at least one disposable sensor device is configured to sense one or more physical or chemical parameters of contents of the blood circuit tube;
wherein the not more than one substantial biochemically disposable sensor unit is operatively placed one of;
upstream of the dialyzer;
or within the dialyzer.

Abstract
The invention is a hemodialysis system in which at least one disposable sensor is combined with a dialysis circuit, in combination with an optional transceiver, to provide real-time or near-real-time patient data. Sensors for any or all of blood pressure, conductivity, temperature, oxygenation, sodium levels, calcium levels, phosphorus levels, urea levels, potassium levels, without limitation, may be included in the blood circuit. Preferably, the sensors are MEMS or ISFET sensors and are positioned in the overall system upstream of, or within the upstream portion of, the dialyzer.
