Abstract
A system includes a cuvette including a cuvette body forming a substantially planar exterior surface and having a sensor window defined within the substantially planar exterior surface. The cuvette further includes a probe retention structure extending from the cuvette body. The system includes a probe with a probe body and a protrusion that is removably coupled to the probe retention structure.
Claims20
A cuvette comprising:
- a cuvette body having a first end, a second end, an aperture positioned between the first end and the second end, and a central bore extending from the first end to the second end to permit blood flow therethrough, wherein the aperture extends through a side wall of the cuvette body;
- and
- a sensor window formed separate from the cuvette body and thereafter being positioned within the aperture of the cuvette body, the sensor window providing visual and/or sensor access to blood within the central bore while preventing blood flow through the aperture;
- wherein the sensor window includes a fluorescent coating sensitive to blood oxygen partial pressures.

A system comprising:
- a cuvette comprising:
- a cuvette body including a first cuvette end, a second cuvette end, an aperture positioned between the first cuvette end and the second cuvette end, and a central bore extending from the first cuvette end to the second cuvette end to permit blood flow therethrough, wherein the aperture extends completely through a side wall of the cuvette body;
- a sensor window formed separate from the cuvette body and thereafter being positioned within the aperture of the cuvette body, the sensor window providing visual and/or sensor access to blood within the central bore while preventing blood flow through the aperture;
- a first probe retention structure positioned near the first cuvette end;
- and
- a second probe retention structure extending from the cuvette body and positioned near the second cuvette end;
- wherein the sensor window includes a fluorescent coating sensitive to blood oxygen partial pressures;
- and
- a probe comprising:
- a probe body having a first probe end and a second probe end;
- a first cuvette engaging structure near the first probe end capable of removably engaging the first probe retention structure;
- and
- a second cuvette engaging structure near the second probe end capable of engaging the second probe retention structure.
