Abstract
Some embodiments of the invention provide a single apparatus that is suitable for both spectroscopic and biosensor measurement of a fluid sample. Once the fluid is transferred to the apparatus, the apparatus can be inserted into a slot in a diagnostic measurement instrument for rapid fluid analysis. Because the apparatus is small and no pretreatment of the fluid is necessary, the diagnostic measurement instrument may be in the form of an inexpensive hand-held instrument, which could be used at the site of patient care. In some very specific embodiments, the apparatus is provided with two independent flow paths for analysis of the fluid. One flow path includes an optical chamber and the second flow path includes at least one biosensor.
Claims18
A fluid measurement apparatus comprising:
- a housing;
- an inlet within the housing for receiving a fluid to be tested;
- a first flow path for receiving the fluid from the inlet, wherein the first flow path comprises an optical chamber having at least one optical window for performing spectrometry on the fluid;
- a second flow path for receiving the fluid from the inlet, wherein the second flow path comprises a biosensor chamber having at least one biosensor for performing tests on the fluid;
- and
- a vent for facilitating airflow out of the first flow path and the second flow path when the inlet receives the fluid.
