Claims

1. Bag (1 ) made of a flexible wall, which bag is fitted with an inlet fluid line for introducing dissolution water, and with an outlet fluid line for extracting a solution obtained, characterised in that the inside of the bag has a lower edge (13, 132) in the overall shape of a V, the point (132) of the V being further away from the centre of the bag than the arms of the V, the outlet fluid line opening into the bag as close as possible to the point of the V.

2. Bag (1 ) according to the preceding claim, characterised in that the joining area (132) between the two arms of the V (13) is rounded.

3. Bag (1 ) according to one of the preceding claims, characterised in that, the two arms of the V (13) have the same inclination and/or the joining area (132) between the two arms of the V (13) is located at the centre of the lower edge (13, 132).

4. Bag (1 ) according to one of the preceding claims, characterised in that the angle (a) between the two arms of the V (13) is comprised between 65° and 75°.

5. Bag (1 ) according to one of the preceding claims, characterised in that the arms of the V (13) are obtained by welding the bag onto itself.

6. Bag (1 ) according to one of the preceding claims, characterised in that the lower edge (13, 132) extends after each arm of the V (13), on the opposite side to the point of the V, by an intermediate area (15) made up

- of a concave shoulder (151 ), of which the gradient at the junction with the arms of the V (13) is less than the gradient of the arms of the V (13), and of which the gradient at its opposite end is close to vertical, and/or

- of a constriction nose (152) projecting towards the centre of the bag to form an elbow.

7. Bag (1 ) according to one of the preceding claims, characterised in that the bag is made of two panels joined together via their outer edges, preferably by welding.

8. Bag (1 ) according to one of the preceding claims, characterised in that the inside of the bag has an upper edge (11 a), a V-shaped lower edge (13, 132) and two lateral edges (1 1 b, 1 1 d) each one connecting one end of the lower edge to the corresponding end of the upper edge, if appropriate with the interposition of an intermediate area between the V-shaped lower edge and the lateral edges, if appropriate with the interposition of an intermediate area (15) between the V-shaped lower edge (13, 132) and the lateral edges (1 1 b, 1 1 d).

9. Bag (1 ) according to the preceding claim, characterised in that the bag has a rectangular overall shape, the point of the V being located in the middle of one of the short sides of the rectangle, the bag extending beyond the V-shaped lower edge, on each side of the V, to an external lower edge (1 1 c) parallel to the upper edge (1 1 a), the external lower edge (1 1 c) preferably being at least partially coincident with the lower edge (13, 132) at the point of the V (132), the lateral edges (1 1 b, 1 1 d) preferably extending to the external lower edge (1 1 c).

10. Bag (1 ) according to one of the preceding claims, characterised in that the inlet fluid line opens into the bag opposite the point of the V.

1 1 . Bag (1 ) according to one of the preceding claims, characterised in that the outlet fluid line comprises a tube (121 ) a first end of which is fitted with a filter (121 ), the tube being dimensioned to allow the filter to be positioned as close as possible to the point of the V (132).

12. Bag (1 ) according to one of the preceding claims, characterised in that the bag is fitted with a connector (12) for connecting it to a haemodialysis generator, the connector being crossed by the inlet fluid line and a first portion of the outlet fluid line, which first portion preferably being located opposite the point of the V, and which first portion is extended by a tube (121 ) fitted at its opposite end with a filter (122) positioned as close as possible to the point of the V (134).

13. Bag (1 ) according to the preceding claim, characterised in that the connector (12) is inserted into an edge of the bag some distance away from the V-shaped lower edge (13, 132), preferably into an upper edge (1 1 a) opposite the V-shaped lower edge, or in that the connector is inserted into the wall of the bag some distance away from the V-shaped lower edge (13, 132).

14. Bag (1 ) according to one of the preceding claims, characterised in that the bag contains bicarbonate for the production of a saturated solution for dialysis.
