Abstract
An apparatus for proportioning solutions from at least first and second constituent solutions connected to separate inlet ports of the apparatus first detects which constituent solution is being supplied to which port and then properly proportions the finished solution from the constituent solutions irrespective of which constituent solution is connected to which inlet port.
Claims25
An apparatus for proportioning solutions from water and at least first and second concentrates comprising,
- a. proportioning apparatus having at least first and second inlet ports;
- b. means for supplying water to said apparatus;
- c. at least one source of said first concentrate in fluid connection with said first inlet port and at least one source of said second concentrate in fluid connection with said second inlet port;
- d. means for separately determining which concentrate is supplied to each of said inlet ports and adapting said apparatus to properly compound said solution according to predetermined parameters from said concentrates and said water irrespective of the particular inlet port to which each said concentrate is connected from said respective sources.
An apparatus for proportioning finished solutions from at least first and second constituent solutions, said first constituent solution having a low conductivity and said second constituent solution having a high conductivity, said apparatus comprising,
- a. a compounding apparatus having at least first and second inlet ports;
- b. a first source of said first constituent solution in fluid connection with said first inlet port and a second source of said second constituent solution in fluid connection with said second inlet port;
- d. means for separately detecting which solution is supplied to each of said inlet ports and adapting said machine to properly proportion said finished solution according to predetermined parameters from said first and second constituent solutions irrespective of the particular inlet port to which each is supplied from said respective sources.
An apparatus for proportioning dialysis solutions from water and at least first and second concentrates comprising,
- a. a proportioning machine having at least first and second inlet ports;
- b. at least one source of water connected to said apparatus;
- c. a least one source of said first concentrate in fluid connection with said first inlet port and at least one source of said second concentrate in fluid connection with said second inlet port;
- d. means for separately detecting which concentrate is supplied to each of said inlet ports and adapting said apparatus to properly proportion said solution from said concentrates and said water irrespective of the particular inlet port to which each is connected from said respective sources,
In a dialysis machine having multiple inlet ports and means for proportioning dialysis solutions from at least two concentrates and water supplied to different of said inlet ports, the improvement comprising in combination;
- means for detecting which concentrate is supplied to each said inlet port and for automatically adapting said machine to properly proportion said solutions from said concentrates and said water regardless of which concentrate is supplied to which inlet port.
A method for proportioning dialysis solutions from water and at least first and second concentrates comprising the steps of:
- providing a source of water;
- providing a source of first concentrate;
- providing a source of second concentrate;
- coupling the source of water to a water inlet of a proportioning apparatus that also includes at least first and second inlets;
- coupling the first source of first concentrate to either the first inlet or the second inlet;
- coupling the second source of second concentrate to the other inlet;
- determining automatically which concentrate is coupled to which inlet;
- and
- causing the proportioning apparatus to properly compound a solution, according to predetermined parameters, from the concentrates and the water irrespective of the inlet port to which the concentrates are connected.
A method of providing dialysis to a patient comprising the steps of:
- providing a dialysis machine having multiple inlet ports and means for proportioning dialysis solutions from at least two concentrates and water supplied to different of said inlet ports;
- allowing the dialysis machine to automatically detect which of the at least two concentrates is supplied to each of the inlets;
- and
- automatically adapting the machine to properly proportion the solutions from said concentrates and said water regardless of which concentrate is supplied to which inlet port.
A method of providing dialysis to a patient comprising the steps of:
- providing a dialysis machine having multiple inlet ports and means for proportioning dialysis solutions from at least two concentrates and water supplied to different of said inlet ports;
- allowing the patient to couple the at least two concentrates to either of at least two inlet ports;
- allowing the dialysis machine to automatically detect which of the at least two concentrates is supplied to each of the inlet ports;
- and
- automatically adapting the machine to properly proportion the solutions from said concentrates and said water regardless of which concentrate is supplied to which inlet port.
