Abstract
A measurement cell (3) for measuring at least one constituent of a liquid sample, in particular blood, includes a reception space (9) for receiving the sample includes a measurement system (8) having at least one sensor electrode (10) exposed within the reception space; a first heat supply equipment (12) extending over a first area (91); a second heat supply equipment (14) extending over a second area (93), the first and second heat supply equipment being arranged to heat the sample within the reception space (9), wherein the second area (93) is larger than the first area (91).
Claims19
Measurement cell for measuring at least one constituent of a liquid sample, the measurement cell including:
- a reception space for receiving the sample;
- a measurement system having at least one sensor electrode exposed within the reception space;
- a first heat supply equipment extending over a first area;
- a second heat supply equipment extending over a second area, the first and second heat supply equipment being arranged to heat the sample within the reception space, wherein the second area is larger than the first area;
- a sample supply system attached to an inlet to allow supply of a liquid sample into the reception space, wherein the sample supply system includes a supply needle connected at one end to the inlet, the supply needle having a lumen in communication with the reception space;
- and
- a trail engagement portion.
Method for manufacturing a measurement cell for measuring at least one constituent of a liquid sample, the method comprising:
- arranging a first heat supply equipment extending over a first area on a first insulating layer;
- arranging a second heat supply equipment extending over a second area on a second insulating layer, the second area being larger than the first area;
- arranging at least one sensor electrode of a measurement system on a top insulating layer;
- stacking the first layer on top of the second layer;
- stacking the top layer on top of the first layer;
- and
- forming a reception space for receiving the sample above the top layer by attaching a cover portion onto the top layer such that the sensor electrode is exposed within the reception space.
