Abstract
A dialysis apparatus, comprising an elongated flow passage with a water inlet and a brine outlet end, a pump at the outlet end for draining brine from the passage, a reservoir of brine concentrate in the passage, means for diluting the brine with water and adjusting salinity of the brine solution in the passage, a heater in the passage downstream of the reservoir for heating the brine solution after its salinity has been stabilized, a deaerator in the passage for breaking up the brine bubbles and removing air therefrom, a blood dialysis unit connected to the passage for purifying the blood of a patient whose bloodstream is connected to the unit, and pressure adjustment means connected to the passage for adjusting the pressure of brine passing to the unit.
Claims9
A dialysis apparatus comprising:
- an elongated flow passage having a water inlet at one end and a fluid discharge at the other end;
- a reservoir containing a brine concentrate said reservoir communicating with portions of said passage downstream of said water inlet so that water enters said reservoir to force said brine concentrate out of said reservoir and into said passage;
- a water inlet tube connected between said passage and said reservoir and in direct communication with said brine concentrate in said reservoir;
- a brine outlet tube connected to said reservoir and to said passage downstream of said water inlet tube;
- a restrictor means in said passage between said water inlet tube and said brine outlet tube for permitting water to flow therethrough at a pressure lower than the water pressure applied to said water inlet tube whereby said brine concentrate entering said passage from said brine outlet tube will be diluted by the water passing through said restrictor means to form a brine solution;
- a conductivity detector means in said passage downstream of said brine outlet tube for detecting changes in the conductivity of said brine solution;
- valve means in said brine outlet tube operable by said conductivity detector means for controlling flow of said brine concentrate through said brine outlet tube;
- spaced inlet and outlet tubes connected to said passage downstream from said conductivity detector means for connecting a blood dialyzer device to said passage;
- and
- a pump downstream of said dialyzer device having an inlet connected to said passage for drawing said brine solution through said dialyzer and an outlet for discharging said brine solution to a drain.
