RMR062791 PATENT 0143R Docket No. 91H987 A filter having a microporous hydrophilic membrane is utilized in a thermodilution set up wherein the filter is positioned downstream from the injectate reservoir, the syringe and most of the fittings through which bacteria or other harmful materials could enter the bolus of injectate. The filter thus traps bacteria and particulates and prevents the material that may have inadvertently entered the injectate stream from being introduced into the patient. The filter is relatively inexpensive and is commercially available having a pore size of about 0.2 um while allowing typical thermodilution injactate flows of about 150 cc/min.
