Abstract

A mobile dialysis fluid generation system includes a cargo unit configured to be transported by a vehicle; a cleanroom located inside the cargo unit; water purification equipment; at least one dialysis fluid preparation unit located inside the cleanroom; and at least one area provided outside the cleanroom but inside the cargo unit for storing at least one of a raw material or containers filled with dialysis fluid. The at least one dialysis fluid preparation unit includes at least one concentrate, a mixing device configured to receive purified water from the water purification equipment and to mix the purified water with the at least one concentrate to form dialysis fluid, and a tubing set for transfer of the dialysis fluid from the mixing device to a container positioned and arranged to receive the dialysis fluid.

First claim

The invention claimed is:

1 . A mobile dialysis fluid generation system comprising:
a cargo unit configured to be transported by a vehicle; a cleanroom located inside the cargo unit; water purification equipment; at least one dialysis fluid preparation unit located inside or outside the cleanroom, the at least one dialysis fluid preparation unit including
at least one concentrate,
a mixing device configured to receive purified water from the water purification equipment and to mix the purified water with the at least one concentrate to form a dialysis fluid,
a tubing set for transfer of the dialysis fluid from the mixing device to a container positioned and arranged inside the cleanroom to receive the dialysis fluid; and
at least one area provided outside the cleanroom but inside the cargo unit for storing at least one of a raw material or containers filled with dialysis fluid.

2 . The mobile dialysis fluid generation system of claim 1 , wherein the cleanroom includes a laminar flow hood positioned and arranged to direct purified air in a laminar manner to a location at which the dialysis fluid is received by the container.

3 . The mobile dialysis fluid generation system of claim 2 , which includes a plurality of the containers configured to receive dialysis fluid from at least one dialysis fluid preparation unit, and wherein the laminar flow hood includes a tilted tray for holding and angling one of the plurality of the containers upwardly for connecting to a filling line delivering the dialysis fluid.

4 . The mobile dialysis fluid generation system of claim 3 , wherein the tilted tray is configured to swivel so that the container angled by the tilted tray may be directed upwardly to an open filling line extending from one or more of mixing device.

5 . The mobile dialysis fluid generation system of claim 1 , wherein the water purification equipment is located inside the cleanroom and includes at least one form of purification selected from the group consisting of: reverse osmosis (“RO”), ultraviolet (“UV”) radiation, electrodeionization, ultrafiltration, ion-exchange resins, heat disinfection, distillation, and forward osmosis.

6 . The mobile dialysis fluid generation system of claim 1 , which includes a conveyor leading from inside the cleanroom to outside the cleanroom.

7 . The mobile dialysis fluid generation system of claim 1 , wherein the mixing device includes a dialysis machine configured to receive purified water from the water purification equipment and to mix the purified water with the at least one concentrate to form dialysis fluid.

8 . The mobile dialysis fluid generation system of claim 7 , wherein the dialysis machine is operated in a non-treatment mode while receiving purified water from the water purification equipment and mixing the purified water with the at least one concentrate to form dialysis fluid.

9 . The mobile dialysis fluid generation system of claim 8 , which includes a recirculation container in recirculation fluid communication with the dialysis machine to enable operation of the dialysis machine in the non-treatment mode.

10 . The mobile dialysis fluid generation system of claim 7 , wherein the tubing set is provided with a filter downstream of the dialysis machine and upstream from the container, the filter provided with at least one connector blocked so that dialysis fluid delivered from the dialysis machine to the filter is forced through pores of a plurality of membranes housed by the filter for filtration of the dialysis fluid.

11 . The mobile dialysis fluid generation system of claim 10 , wherein the tubing set includes an outlet line leading from the filter to the container, and wherein the outlet line includes at least one additional filter.

12 . The mobile dialysis fluid generation system of claim 1 , wherein the tubing set includes a plurality of containers positioned and arranged to receive the dialysis fluid, and which includes a filter located upstream and/or downstream of the plurality of containers.

13 . The mobile dialysis fluid generation system of claim 12 , wherein the filter is (i) a reusable filter including an ultrafilter or dialyzer or (ii) a sterile sterilizing grade filter packaged with the tubing set.

14 . The mobile dialysis fluid generation system of claim 12 , wherein the filter is packaged and presterilized with the plurality of containers.

15 . The mobile dialysis fluid generation system of claim 12 , which includes a tilted tray for holding and angling the filter upwardly for connecting to a filling line delivering the dialysis fluid.

16 . The mobile dialysis fluid generation system of claim 1 , which includes at least one of a weigh scale or a timer for controlling an amount of dialysis fluid received by plurality of the containers.

17 . The mobile dialysis fluid generation system of claim 1 , wherein the at least one concentrate is configured to prepare dialysis fluid for a blood treatment or peritoneal dialysis, or an intravenous fluid including saline, an NaCl fluid or a nutritional fluid.

18 . A mobile medical fluid generation system comprising:
a cargo unit configured to be transported by a vehicle; a cleanroom located inside the cargo unit; water purification equipment located inside the cargo unit; at least one medical fluid preparation unit located inside or outside the cleanroom, the at least one medical fluid preparation unit including:
at least one concentrate located inside the cargo unit;
a mixing device configured to receive purified water from the water purification equipment and to mix the purified water with at least one concentrate to form a medical fluid, the mixing device being located inside the cargo unit;
a container positioned and arranged inside the cleanroom to receive the medical fluid, and
a tubing set configured to transfer of the medical fluid from the mixing device to the container; and
at least one area provided outside the cleanroom but inside the cargo unit for storing at least one of a raw material including multiple tubing sets or containers filled with medical fluid.

19 . The mobile medical fluid generation system of claim 18 , wherein the medical fluid is a blood treatment dialysis fluid, a peritoneal dialysis fluid, or an intravenous fluid including saline, lactated ringers, an NaCl fluid or a nutritional solution.

20 . The mobile medical fluid generation system of claim 18 , wherein one or more of the water purification equipment, the at least one concentrate, and the mixing device is located inside the cleanroom.

21 . The mobile medical fluid generation system of claim 18 , wherein the tubing set includes at least one sterile sterilizing grade filter for further filtering the medical fluid before reaching the container.

22 . A medical fluid generation system including a modular cleanroom for generating dialysis fluid, the modular cleanroom comprising:
water purification equipment; at least one container positioned and arranged to receive the dialysis fluid; at least one dialysis fluid preparation unit including:
