Abstract
A method for monitoring blood/tissue gases, blood pH, and other elements of blood and tissue chemistry is described that uses a sensor tip that is placed adjacent to the conjunctiva of a patient to be monitored. Monitors and sensor using optical fiber sensors for performing the monitoring are also described.
Claims58
A method for monitoring blood and tissue gas or pH of a patient, comprising
- placing an optical blood and tissue gas monitor sensor tip adjacent the conjunctiva of said patient, wherein said sensor tip comprises at least one optical sensor fiber for detecting at least one blood and tissue gas or blood and tissue pH and said sensor tip is connected with analysis and display components of a blood monitor system;
- determining patient blood and tissue gas or pH values or both with said monitor system;
- and
- recording or displaying said patient blood and tissue gas or pH values or both.

A conjunctival monitor, comprising
- a sensor comprising a sensor tip with a detection length of 2 cm or less adapted to fit adjacent the conjunctiva of a patient's eye, comprising at least one optical sensor fiber.
A disposable sensor for a conjunctival monitor, comprising
- a sensor tip comprising at least two of a pH sensor fiber or electrode, a PCO2 sensor fiber or electrode, and a PO2 sensor fiber or electrode, wherein said sensor tip has a thickness of 0.5 mm or less;
- a sterile packaging enclosing at least the portion of said sensor tip that contacts the conjunctiva of a patient during use;
- and
- a written indication for use of said sensor for conjunctival monitoring.
