Abstract
A sensor assembly for a bodily fluid analyzer includes a reference electrode container containing a reference electrode, a membrane capable or configured to be in fluid communication with the reference electrode container; and a wicking member capable or configured to be in fluid communication with the reference electrode container. The wicking member is configured to draw a reference fluid contained in the reference electrode container towards the membrane when the membrane and the wicking member are exposed to the reference fluid.
Claims28
A sensor assembly for a bodily fluid analyzer, comprising:
- a reference electrode container containing a reference electrode, wherein the reference electrode container is configured to house a reference fluid;
- a membrane configured to be in fluid communication with the reference electrode container;
- and
- a wicking member configured to be in fluid communication with the reference electrode container, wherein the wicking member is configured to draw the reference fluid towards the membrane when the membrane and the wicking member are exposed to the reference fluid.
A fluid analyzer, comprising:
- a sample receiving assembly having a sample probe with a fluid inlet and a fluid outlet;
- a fluid waste assembly;
- and
- a sensor assembly in fluid communication with the sample receiving assembly and the fluid waste assembly, the sensor assembly comprising:
- a reference electrode container containing a reference electrode, wherein the reference electrode container is configured to house a reference fluid;
- a membrane configured to be in fluid communication with the reference electrode container;
- and
- a wicking member configured to be in fluid communication with the reference electrode container, wherein the wicking member is configured to draw the reference fluid towards the membrane when the membrane and the wicking member are exposed to the reference fluid.
