Definitions

  • ABSTRACT I301 Forelgn Apphcauoni pnomy Data A system for supplying a blood dialyser with dialysing M111. 14, I972 Great Blltkllli onnections enabling the ystem to be connected with the dialyser blood compartment, so that [52] U.S. Cl. 134/22 R, 134/22 C, 134/26, fte a di l ing treatment, the supply system can be 134/42, 210/22, 210/321 used to supply washing and sterilizing liquid both to [51] int.
  • the blood compartment of a dialyser to the dialysate production and supply system of the machine and utilize the system to supply liquid to both the blood and dialysate compartments of the dialyser for washing and/or sterilizing purposes.
  • dialysate production and supply system of an artificial kidney machine with connections enabling the system to be connected with a blood circuit of a dialyser so that liquid from the supply system can be delivered to the dialyser blood compartment for washing and/or sterilizing purposes after completion of adialysis treatment.
  • the machine comprises a dialysate production and delivery system A and a dialyser B which may be of the parallel flow, coil or capillary type.
  • System A includes a dialysate production arrangement 1 not shown in detail in the drawing but comprising conventional mainswater and dialysate mixing and concentration control means 1 and conventional mixture heating means 1', the arrangement 1, 1' supplying dialysate to the base of a first header tank 2 from where the dialysate circulates through a de-aerating conventional circuit 3 and is pumped into a second header tank 4 linked to the first tank as shown. (Tanks 2 and 4 could be combined into a single partitioned tank).
  • Tank 4 has an overflow 5 leading into a third tank 6 on a lower level, tank 6 itself having an overflow 7 going to drain.
  • a connection 8 from tank 4 leads to the dialysate compartment or compartments of the dialyser and during a dialysis treatment, dialysate is constantly drawn through the dialyser from tank 4 by a pump 9 and discharged to the drain, the dialysate supply being continuously replenished by the production system, which is run so that tanks 2, 4 and 6 are all kept flushed with liquid.
  • the blood compartment or compartments of the dialyser continuously receive blood from a patient through a blood circuit comprising an intravascular needle fitting, a supply line 10 and blood pump 11, the blood being returned to the patient from the dialysis through a further blood line 12 and needle fitting.
  • dialysate is continuously pumped through the dialysate compartment(s) of the dialyser while a patients blood is continuously circulated by the blood circuit, through the blood compartment(s) of the dialyser.
  • the circuits can be charged with a sterilizing medium, by the introduction of a sterilizing conce'ntrate such as formalin concentrate from a supply 15 to the tank 2 by the operation ofa pump 16 and continued operation of pumps 9 and 11 for a time sufficient fully to circulate the sterilizing mixture.
  • a sterilizing medium such as formalin concentrate from a supply 15 to the tank 2 by the operation ofa pump 16 and continued operation of pumps 9 and 11 for a time sufficient fully to circulate the sterilizing mixture.
  • the sterilizing medium may be introduced by venturi means and it could be introduced into the line 1 instead of into the tank 2.
  • the invention provides an in situ method of washing both the blood and dialysate compartments of the dialyser utilizing the dialysate supply system of the machine. Moreover, the invention provides a method of distributing a concentrated toxic sterilizing solution, such as a formalin-solution, after dilution, to the dialyser without the necessity of handling the concentrated solution and without the effects of having toxic vapours from the solution within the system environment. This is of particular importance for individuals with sensitive skins.
  • a concentrated toxic sterilizing solution such as a formalin-solution
  • a method as recited in claim 1 wherein the step of connecting the blood compartment of said dialyser to said dialysate supply system is accomplished by connecting ends of ablood circuit, said ends previously having been attached to a patients blood supply, containing said blood compartment and a blood pump to said dialysate supply system so that said blood pump circulates liquid from said supply system through said blood circuit.
  • a method as recited in claim 3 wherein the method comprises the additional step of washing both said compartments of said dialyser with pure heated and deaerated water from said supply system after said washing with dialysate.
  • a method as recited in claim 1 wherein the method comprises the additional step of providing a sterilizing medium to said supply system to supply said sterilizing medium to both said compartments of said dialyser after said washing of said compartments.
  • a dialysate supply system for an artificial kidney machine with a dialyser having a blood circuit including blood supply lines and blood and dialysate compartments said supply system comprising means for producing dialysate by mixing water with metered quantities of dialysate concentrate and heating and deaerating the mixture, and connection means for connecting said supply system with said dialyser blood circuit so that after a blood dialysate treatment liquid from said supply system can be delivered to said dialyser blood compartment for washing said compartment.
  • one of said tanks is an overflow tank from the other of said tanks.
