Dish-electrode concentration meter with detachable transducer
First Claim
1. An improved dish-electrode concentration transducer unit of the type including a dish-defining structure of thermally conductive material forming a dish into which a quantity of blood on the order of 20-50 microliters is dropped and including a concentration transducer, the improvement comprising a transducer housing of insulating material accommodating the thermally conductive dish-defining structure and forming a transducer compartment in which the transducer is accommodated;
- means pressing the concentration transducer into thermal engagement with the thermally conductive material of the dish-defining structure;
quick-disconnect electrical connectors on the transducer housing for electrically connecting the concentration transducer to a power supply and to an indicator unit and including leads connected to the quick-disconnect electrical connectors and extending away from the transducer housing.

Abstract
A dish-electrode concentration transducer unit of the type into whose dish one or a few drops of blood, on the order of 20-50 microliters, is dropped. The dish-defining structure of the transducer unit is thermally conductive, and both it and the transducer of the unit are thermostatically temperature-controlled, in order that the transducer and the blood being investigated be maintained at requisite temperature. The transducer is, in assembled condition of the transducer unit, held in place pressed against the thermally conductive dish-defining structure so as to be in thermally conductive engagement therewith. Accordingly, the transducer of the unit can be replaced with involvement of the heating element or temperature sensor of the thermostatic system of the transducer unit, and certainly without accompanying replacement of the temperature sensor.
