ABSTRACT:
An automatic syringe drive assembly and disposable heat exchanger cassette are used in combination to provide an improved thermodilution technique and apparatus. The automatic syringe drive assembly includes replaceable connecting rods on a slider crank mechanism which permit easy and accurate adjustment of the syringe injection volume. The drive assembly supports an insulated syringe for use in making the injection. The heat exchanger cassette includes a heat transfer plate and a thermoformed plastic labyrinth adhesively connected and used in combination with a thermoelectric chiller to provide a cold bolus of injectate.
