A proportioning-type dialysis machine is disclosed for preparing dialysis solution from water and dialysis concentrate, delivering fresh dialysis solution to a dialyzer and discharging spent dialysis solution. The machine includes inlet means through which water enters the machine from an external source, a reservoir for receiving and holding liquid, outlet means through which spent dialysis solution exits the machine, and a heat exchanger and heater for heating said water to a predetermined physiological temperature. The heat exchanger is positioned downstream of the inlet means and upstream of the reservoir and the heater and is constructed to permit flow therethrough of water flowing from the inlet means to the reservoir and heater. The heat exchanger is also positioned and constructed to permit flow therethrough of warm spent dialysis solution flowing from a dialyzer to said outlet means, and so as to maximize the transfer of heat from the spent dialysis solution to the entering water. |
