Patent Images
1. A device for periodically monitoring at least one predetermined parameter of blood from a patient, comprising:
- access device for gaining access to said blood with a catheter;
a pump to withdraw blood from the patient in a predetermined time schedule;
a dispenser to dispense a small amount of blood and provide a blood sample;
at least one sensor in contact with said blood sample;
a controlled volume pump for transporting fluid through the system; and
a signal processor to measure a signal produced by the at least one sensor upon contact with the blood sample where the signal is indicative of said at least one predetermined parameter.

Abstract
The present invention is directed towards apparatuses and methods for the automated measurement of blood analytes and blood parameters for bedside monitoring of patient blood chemistry. Particularly, the current invention discloses a programmable system that can automatically draw blood samples at a suitable programmable time frequency (or at predetermined timing), can automatically analyze the drawn blood samples and immediately measure and display blood parameters such as glucose levels, hematocrit levels, hemoglobin blood oxygen saturation, blood gases, lactate or any other blood parameter.
