Point of care device

Apparatus and methods in accordance with one or more preferred embodiments of the present invention are used to measure nitric oxide in a fluid, and each includes a sample injection port; a pump; a measurement chamber; an electromagnetic radiation source; one or controls and user interfaces; and a cartridge. The cartridge includes a sample chamber; an electromagnetic radiation and heat chamber; and a gas permeable membrane. The cartridge preferably is single-use and disposable. Further apparatus and methods in accordance with other alternative embodiments, and additional inventive aspects and features, are disclosed related to measuring nitric oxide in a fluid.

Measuring nitric oxide in fluid

A device includes a first sensor coupler that is configured to receive a first input signal from a first sensor. The first input signal corresponds to a first physiological parameter and is based on optical excitation of a tissue. The device includes a processor coupled to the first sensor coupler. The processor is configured to generate an output signal based on the first input signal. The first physiological parameter is encoded in the output signal. The output signal differs from the first input signal. The device includes an output coupler configured to communicate the output signal to a remote device.

Oximetry with remote display

An exemplary apparatus for measuring nitric oxide in a fluid includes a sample injection port; a pump and reservoir; a valve; a measurement chamber; an electromagnetic radiation source; controls and user interface; and a cartridge. The cartridge includes a sample chamber a mix chamber; a sample degassing chamber; and a planar reaction chamber. The cartridge preferably is single-use and disposable. Furthermore, additional inventive aspects and features are disclosed related to measuring nitric oxide in a fluid.

Methods and apparatus for measuring nitric oxide in fluid

A system for operating at least first and second amperometric sensors includes a cartridge and a control device. The cartridge includes a first amperometric sensor and a second amperometric sensor. The first amperometric sensor is in fluid flow communication with a liquid sample inlet and includes a first electrode. The second amperometric sensor is in fluid flow communication with a liquid sample and includes a second electrode. The control device sets the first and second electrodes to about the same potential such that the first and second amperometric sensors can be operated simultaneously.

Apparatus and method for analytical determinations using amperometric techniques

An apparatus and method for measuring conductance are provided. The method and apparatus are particularly well adapted for use with a removable or replaceable cartridge in a blood analysis system. The apparatus generally involves providing a system having a first, unfiltered, conductance measurement cell and a second, filtered, conductance measurement cell. The preferred method involves relating values measured in the two cells for a whole blood sample and for a known calibrant together, to obtain a value, for example hematocrit, for the unknown whole blood sample.
