Abstract
Disclosed is a sensor assembly 100 including a sensor body having a flow channel therein configured to receive a test liquid, such as a bio-liquid, one or more moveable walls defining one or more wall portions of the flow channel, the one or more moveable walls configured to be moveable, such as to a first position, a second position, or even an intermediate position, to change a volume of the flow channel 102, and one or more sensor elements positioned in the flow channel. Volume in the flow channel may be minimized for testing neonatal specimens. Liquid testing apparatus and methods of testing test liquids are provided, as are other aspects.
Claims18
A sensor assembly, comprising:
- a gas pressure source;
- a sensor body having a flow channel configured to receive a test liquid therein, one or more moveable walls that continuously define at least one sidewall of the flow channel along a length of the flow channel, the one or more moveable walls configured to be moveable via pressurized gas provided by the gas pressure source to displace the sidewall itself and change a volume of the flow channel;
- and
- one or more sensor elements positioned in the flow channel.
