System and method for providing sterile fluids for admixed solutions in automated peritoneal dialysis

A method for mixing fluids during delivery to a peritoneal cavity of a patient, the method comprising the steps of:

• providing a first container holding a first fluid;
• providing a second container holding a second fluid;
• connecting the first container to a first pumping means and a second pumping means such that either pumping means may pump fluid from said first container;
• such that either pumping means may pump fluid from said first container
• connecting the second container to the first pumping means and the second pumping means;
• connecting the first and second pumping means to an intermediate container;
• automatically withdrawing the first fluid and the second fluid from their respective containers with the first and second pumping means sequentially or simultaneously and pumping the first fluid and second fluid to the intermediate container;
• mixing the first fluid and the second fluid forming a mixed solution in the intermediate container;
• and
• directly delivering the mixed solution from the intermediate container to the peritoneal cavity of the patient following mixing.

A method for direct infusion of a plurality of fluids to a peritoneal cavity of a patient, the method comprising the steps of:

• providing at least two containers including a first container and a second container;
• filling the first container with a first one of the plurality of fluids;
• directly pumping the first one of the plurality of fluids to the peritoneal cavity of the patient with one of a first pumping means or a second pumping means;
• filling the second container with a second one of the plurality of fluids;
• and
• directly pumping the second one of the plurality of fluids to the peritoneal cavity of the patient with one of the first pumping means or the second pumping means.

A system for infusion of a plurality of solutions to a peritoneal cavity of the patient, the system comprising:

• means for storing each of the plurality of solutions in a plurality of separate containers;
• input means for inputting an amount of each of the plurality of solutions required for delivery to the peritoneal cavity of the patient;
• and
• pumping means for pumping each of the plurality of solutions directly to the peritoneal cavity of the patient including first and second pumping means each being connected to each of the plurality of containers in such a manner that either pumping means may be used to pump fluid from at least on of said containers.
