Blood testing and therapeutic compound delivery system
First Claim
1. A method for determining intravenous blood levels of a target compound contained in a blood vessel of a patient, comprising the steps of:
- detecting concentrations of the target compound within a patient'"'"'s blood using a sensor device configured to optically test blood at a location within the blood vessel;
calculating a measured amount of a therapeutic compound to administer into the patient'"'"'s bloodstream based on concentrations of the target compound detected in the blood; and
pumping a measured amount of therapeutic compound through a catheter into the patient'"'"'s blood.

Abstract
A system and method are provided for determining intravenous blood levels of a target compound contained in a blood vessel of a patient. The method includes the operation of detecting concentrations of the target compound within a patient'"'"'s blood using a sensor device configured to optically test blood at a location within the blood vessel. Another operation is calculating a measured amount of a therapeutic compound to administer into the patient'"'"'s bloodstream based on the concentrations of the target compound in the blood. The measured amount of therapeutic compound may then be pumped through the catheter into the patient'"'"'s blood.

6. A device for responsively delivering therapeutic compounds into a bloodstream, comprising:
-
an intravenous catheter inserted into a blood vessel of a patient;
a detector in optical communication with blood within the blood vessel via the intravenous catheter, the detector being configured to detect at least one target compound in the patient'"'"'s bloodstream;
a processing unit configured to receive detector measurements from the detector and calculate a concentration of the target compound in the patent'"'"'s bloodstream; and
a pump configured to deliver an amount of a therapeutic compound directly into the bloodstream as calculated by the processing unit. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)

16. A device for responsively delivering therapeutic compounds into a bloodstream, comprising:
-
an intravenous catheter inserted into a blood vessel of a patient;
an optical fiber, supported by the intravenous catheter, the optical fiber being configured to deliver optical energy into the blood vessel;
an optical sensor coupled to the optical fiber and configured to receive optical backscatter radiation via the optical fiber in order to detect at least one target compound in the patient'"'"'s bloodstream;
a processing unit configured to receive optical sensor measurements and to calculate the concentration of the target compound in the patent'"'"'s bloodstream; and
a pump configured to deliver an amount of a therapeutic compound directly into the bloodstream as calculated by the processing unit. - View Dependent Claims (17, 18, 19, 20, 21)
