Sensor assembly for measuring analytes in fluids
First Claim
Patent Images
1. Sensor assembly for measuring analytes in fluids comprising:
- a syringe having a body portion with a piston slidable therein, said syringe having a distal end with an outlet port formed therein;
a housing that is a flow through cell having a proximate end with a port formed therein and a distal end with another port formed therein, where the proximate end of the housing engages with and connects to the distal end of the syringe so that a sample of fluid can be drawn through the housing by the syringe, the distal end of the housing adapted for engagement with means for withdrawing a sample of fluid;
sensing means disposed within said housing as an electrode assembly having at least one microsensor prepared by thick film processing for sensing at least one analyte in the sample of fluid including means for connecting said sensing means into a circuit and transmitting a signal to monitor means which measures and displays the value of the analyte sensed by the sensing means.
