<p>Dialysis apparatus is arranged to enable convenient measuring of ultrafiltration rate from liquid, such as blood, that is to be dialyzed. Dialyzer can have, downstream of a dialysis chamber, a dialyzate passageway through which the ultrafiltration flow rate can be readily measured as by introducing a gas bubble into the dialyzate and timing its movement through the passageway. An air-injection attachment can be fitted to the dialyzer or to a dialyzate supply system, to inject the gas bubble for such measurement. Bubble injection can also be effected in a flow rate measuring passageway downstream of the dialyzer. Flow rates of dialyzate into and out of dialyzer can be compared to show ultrafiltration while dialyzing.</p> |
