U.S. Pat. No. 4,919,596, assigned to IVAC Holdings describes a fluid supply monitoring and BloodVitals management apparatus for use in a medication infusion system. What is also needed is a affected person fluid infusion supply system and blood monitoring device whereby the blood measurement unit is located close to the infusion pump, for ease of use in a critical care or surgical setting. Each single use sensor BloodVitals health is advanced sequentially and positioned for direct contact with a blood sample through an advancement means, wherein 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 automatically resumes normal operation of infusion of the external infusion fluid delivery system. Further nonetheless, BloodVitals SPO2 device 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 BloodVitals health tape, as utilized in FIGS.



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



FIGS. 10 a and BloodVitals health 10 b illustrate various strategies for BloodVitals health controlling the movement of fluids in connection to the automated blood analysis device of the present invention, as shown in FIGS. FIG. 12 illustrates a desk of blood bolus volumes in cubic centimeters based on the tube diameter in mm and its size in cm. FIG. 14 illustrates an automatic blood analysis device, similar to that proven in FIGS. FIG. 15 illustrates a gadget just like that described with reference to FIGS. FIG. 18 depicts one other optionally available embodiment of the automated blood evaluation system, wherein a saline bag is added to the system for self-flushing. "clean" and undiluted blood sample. If related in parallel to an infusion fluid delivery system, the system routinely resumes normal infusion operation till the subsequent blood chemistry studying is desired. Optionally, the system disposes of your entire blood sample and simply resumes normal infusion operation.



Either single lumen or a number of lumen tubing buildings are attached to the catheter connected to the vascular entry level. CL ⁇ , Mg, Ca); blood gases (pO 2 , pCO 2 , pH); cholesterol; bilirubin stage; and various different parameters that may be measured from blood or plasma samples. 1 is a device for robotically measuring blood analytes and blood parameters. Automated blood analysis device 1 is linked to a catheter or a venflon (not proven) resulting in the affected person 2 , with a view to routinely collect blood samples and mechanically measure required blood parameters. 1 comprises main unit three ; sensor cassette 5 , which is preferably disposable; waste container 7 ; fluid container 9 ; first infusion pump eleven ; and second infusion pump thirteen . Eleven and second infusion pump 13 are volumetric infusion pumps as are effectively-recognized in the artwork to be used in intravenous fluid administration methods, home SPO2 device although other sorts of pumps similar to peristaltic pumps, piston pumps, BloodVitals health or syringe pumps will also be used.



Also, BloodVitals health however not restricted to such uses, it is most well-liked that first infusion pump 11 is used to regulate the move within the fluid supply line from fluid container 9 and second infusion pump thirteen is used to manage the flow in line 16 used for drawing blood samples to sensor cassette 5 . Automated blood evaluation system 1 also comprises a sequence of tubes, together with line sixteen , which are described in further element under. 1 contains a primary automated three-approach stopcock 15 for controlling the circulation inside line 16 and a second automated three-approach stopcock 17 for controlling the circulation of fluids to and from the exterior tubing and/or exterior units. 15 and second stopcock 17 is ideally totally automated and controlled by predominant unit three . An automatic sampling interface mechanism 18 described in additional element under, allows a blood pattern to be introduced robotically from line sixteen to sensor 19 within sensor cassette 5 .
