## Abstract

An autonomous treatment unit (10, 200) for treating at least a plurality of patients by hemodialysis. The unit being an individual construction comprising at least one care room equipped with a dialysis generator to prepare treatment solutions of at least one of sodium chloride, potassium chloride, calcium chloride, and magnesium chloride with hemodialysis water for each individual patient. The treatment unit is a housing structure grouping of a plurality of elementary modules built substantially in a same way, juxtaposed and arranged internally, individually or in a combination, to form a first group of service rooms (210) assigned for hemodialysis treatment of patients, reception of patients, administrative follow-up of patients and medical follow-up of patients. A second group of rooms (250) for preparation and storage of the concentrates, the fluids used in the care rooms and/or the reprocessing and/or disposal of the residual and effluents generated treatments generated by the treatment.

## Claims

### Claim 1

An autonomous treatment unit (10, 200) for treating at least a plurality of patients by hemodialysis, the unit (10, 200) being an individual construction comprising:
at least one care room equipped with a dialysis generator, and the dialysis generator being arranged to prepare treatment solutions adapted to treat each individual patient of the plurality of patients, and
at least one care room containing the treatment solutions which are prepared by dilution of at least one concentrate, made of at least one solid water-soluble compound, with hemodialysis water, and the solid water-soluble compound comprising at least one of sodium chloride (NaCl), potassium chloride (KCl), calcium chloride (CaCl2), and magnesium chloride, (MgCl2),
wherein treatment unit (10, 200) is built into a housing structure grouping a plurality of elementary modules built substantially in a same way, arranged juxtaposed and in a combination, to form a first group of service rooms (210) assigned to provide for a hemodialysis treatment of each one of the plurality of patients, with the first group of service rooms having dedicated rooms arranged for reception of the plurality of patients, administrative follow-up of the plurality of patients and medical follow-up of the plurality of patients,
a second group of technical rooms (250) for preparation and storage of the concentrates, for preparation and control of the fluids used in the at least one care room and/or the reprocessing and/or disposal of residual and effluents generated during treatments of the plurality of patients, and
each of the elementary modules forming the housing structure comprises a parallelepipedic shape container which comprises a rigid frame, the rigid frame supports at least one side wall, a bottom floor and a roof with a ceiling located adjacent but spaced from the roof, an insulating material is accommodated within the space located between the roof and the ceiling, and a false ceiling is located vertically below the ceiling for accommodating at least one of a forced air circulation network, electrical wiring, air conditioning and conduit, and a trough which contains at least a hemodialysis water supply, a dialysis concentrates supply, and a hemodialysis liquid outlet pipe for discharging fluid.

### Claim 2 (depends on 1)

The autonomous treatment unit (200) according to claim 1, wherein each elementary module has a rigid support located in each corner thereof which is connected with the bottom floor, the roof, the ceiling and the false ceiling.

### Claim 3 (depends on 1)

The autonomous treatment unit (200) according to claim 1, wherein the rigid frame has a metal beam in each corner and at least one metal beam located between a pair of metal beam located in opposite corners of the container.

### Claim 4 (depends on 1)

The autonomous treatment unit (200) according to claim 1, wherein the technical room (210) comprises a removal unit (212), weighing means (213), a preparation unit for the patient's treatment solutions (214), a filtration unit (215) and a unit (216) for filling the containers intended for concentrates storage.
