U.S. Pat. No. 4,919,596, assigned to IVAC Holdings describes a fluid supply monitoring and control apparatus to be used in a remedy infusion system. What is also wanted is a patient 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 crucial care or BloodVitals experience surgical setting. Each single use sensor is advanced sequentially and positioned for direct contact with a blood sample by way of an advancement means, BloodVitals experience whereby the advancement means includes a blood optical sensor for sensing the arrival and departure of undiluted blood within the sensor cassette. Subsequently, the control unit mechanically resumes regular operation of infusion of the external infusion fluid delivery system. Further nonetheless, the combined measurement improves the accuracy of predicting entire blood glucose degree from measured plasma glucose degree. FIGS. Three a - 3 d illustrate a sensor tape, as used in FIGS.

FIGS. 4 a - four d illustrate a sensor tape, as utilized in FIGS. FIG. 6 a is an illustration of a sensor cassette as used in the automated blood analysis gadget of the present invention. FIG. 6 c is an isolated and expanded illustration of the drum structure of a sensor cassette as used in the automated blood analysis device of the present invention. FIG. 6 d is an isolated illustration of the check strip handling mechanism of the sensor cassette as used in the automated blood evaluation machine of the present invention. FIGS. 6 e and 6 f are expanded illustrations of the blood sample supply operation as used within the as used within the automated blood evaluation machine of the current invention. FIGS. 6 g and 6 h are illustrations of the tubing cleansing operation as used in the automated blood evaluation machine of the current invention.

FIGS. 10 a and 10 b illustrate alternative strategies for controlling the stream of fluids in connection to the automated blood analysis system of the current invention, as proven in FIGS. FIG. 12 illustrates a table of blood bolus volumes in cubic centimeters in accordance with the tube diameter in mm and its length in cm. FIG. 14 illustrates an automated blood analysis machine, akin to that shown in FIGS. FIG. 15 illustrates a device much like that described with reference to FIGS. FIG. 18 depicts one other optionally available embodiment of the automated blood analysis system, whereby a saline bag is added to the system for self-flushing. "clean" and undiluted blood sample. If related in parallel to an infusion fluid supply system, the system robotically resumes normal infusion operation until the following blood chemistry reading is desired. Optionally, the system disposes of the complete blood sample and simply resumes normal infusion operation.

Either single lumen or a number of lumen tubing constructions are connected to the catheter hooked up to the vascular entry level. CL ⁇ , Mg, Ca); blood gases (pO 2 , pCO 2 , pH); cholesterol; bilirubin level; and numerous other parameters that can be measured from blood or plasma samples. 1 is a system for automatically measuring blood analytes and blood parameters. Automated blood analysis machine 1 is related to a catheter or a venflon (not proven) leading to the affected person 2 , in order to mechanically accumulate blood samples and mechanically measure required blood parameters. 1 comprises most important unit 3 ; sensor cassette 5 , which is ideally disposable; waste container 7 ; fluid container 9 ; first infusion pump eleven ; and BloodVitals experience second infusion pump thirteen . Eleven and BloodVitals monitor second infusion pump 13 are volumetric infusion pumps as are properly-known within the artwork to be used in intravenous fluid administration systems, though different sorts of pumps similar to peristaltic pumps, piston pumps, or syringe pumps can also be used.

Also, BloodVitals experience but not restricted to such makes use of, it is most well-liked that first infusion pump eleven is used to regulate the movement within the fluid supply line from fluid container 9 and second infusion pump 13 is used to regulate the stream in line 16 used for drawing blood samples to sensor cassette 5 . Automated blood analysis device 1 also includes a series of tubes, including line 16 , that are described in further detail below. 1 contains a first automated three-means stopcock 15 for controlling the flow inside line sixteen and a second automated three-way stopcock 17 for controlling the move of fluids to and from the exterior tubing and/or exterior devices. 15 and second stopcock 17 is ideally absolutely automated and managed by principal unit 3 . An automatic sampling interface mechanism 18 described in additional detail under, enables a blood pattern to be introduced automatically from line sixteen to sensor 19 within sensor cassette 5 .
