US20060079809A1 - Blood Monitoring System - Google Patents
U.S. Pat. No. 4,919,596, assigned to IVAC Holdings describes a fluid supply monitoring and management apparatus for use in a medicine infusion system. What can also be needed is a affected person fluid infusion delivery system and blood monitoring machine whereby the blood measurement unit is positioned near the infusion pump, for ease of use in a critical care or surgical setting. Each single use sensor is advanced sequentially and positioned for direct contact with a blood sample by an development means, whereby the advancement means includes a blood optical sensor for sensing the arrival and departure of undiluted blood inside the sensor cassette. Subsequently, the control unit robotically resumes regular operation of infusion of the exterior BloodVitals insights infusion fluid delivery system. Further nonetheless, the mixed measurement improves the accuracy of predicting whole blood glucose level from measured plasma glucose degree. FIGS. 3 a - three d illustrate a sensor tape, as utilized in FIGS.
FIGS. Four a - 4 d illustrate a sensor tape, as used in FIGS. FIG. 6 a is an illustration of a sensor cassette as used within the automated blood evaluation gadget of the present invention. FIG. 6 c is an isolated and expanded illustration of the drum construction of a sensor cassette as used within the automated blood analysis system of the present invention. FIG. 6 d is an isolated illustration of the take a look at strip dealing with mechanism of the sensor cassette as used within the automated blood analysis device of the current invention. FIGS. 6 e and 6 f are expanded illustrations of the blood pattern delivery operation as used within the as used in the automated blood evaluation gadget of the present invention. FIGS. 6 g and 6 h are illustrations of the tubing cleansing operation as used within the automated blood analysis gadget of the present invention.
FIGS. 10 a and 10 b illustrate various strategies for controlling the stream of fluids in connection to the automated blood analysis device of the present invention, as proven in FIGS. FIG. 12 illustrates a desk of blood bolus volumes in cubic centimeters in keeping with the tube diameter in mm and its length in cm. FIG. 14 illustrates an automatic blood evaluation gadget, such as that shown in FIGS. FIG. 15 illustrates a system similar to that described with reference to FIGS. FIG. 18 depicts another elective embodiment of the automated blood analysis machine, whereby a saline bag is added to the system for self-flushing. "clean" and undiluted blood pattern. If related in parallel to an infusion fluid supply system, the system routinely resumes normal infusion operation till the next blood chemistry reading is desired. Optionally, the system disposes of all the blood sample and merely resumes normal infusion operation.
Either single lumen or BloodVitals insights multiple lumen tubing constructions are connected to the catheter connected to the vascular access point.
