The invention relates to a medical bag which is intended for the infusion of a medicament by means of gravity. The inventive bag comprises: at least two compartments, namely a first compartment (1) containing a medicament in the form of a solution and a second compartment (2) containing a rinsing solution; and means for separating/communicating the compartments, which prevent the rinsing solution from automatically entering the medicament compartment except at the end of the infusion period. The rinsing solution ends the infusion, by rinsing the medicament bag and the infusion line, such as to prevent any risk of contamination or leakage of residual medicament from the bag or line.

What is claimed is: 1. A bag for medical use for infusing medication by gravity, comprising: at least a first compartment and a second compartment, the first compartment configured to contain medication in the form of a solution and the second compartment configured to contain a rinsing solution, a
What is claimed is: 1. A bag for medical use for infusing medication by gravity, comprising: at least a first compartment and a second compartment, the first compartment configured to contain medication in the form of a solution and the second compartment configured to contain a rinsing solution, a separation/communication portion that separates the first compartment and the second compartment, and a breakable device disposed between the first compartment and the second compartment, wherein the separation/communication portion further comprises a communication channel disposed at a first end of the bag above the second compartment when the bag is suspended vertically, and an access port for an infusion line disposed at a second portion of the bag that is disposed at a bottom portion of the first compartment when the bag is suspended vertically, wherein the breakable device prevents communication between the first compartment and the second compartment when not broken, and the breakable device allows communication between the first compartment and the second compartment via the communication channel when broken, wherein the first compartment and the second compartment are juxtaposed, wherein if the breakable device is broken, the rinsing solution is capable of flowing into the first compartment via the communication channel and flowing into an infusion line after the first compartment is almost emptied, the communication channel having an output side disposed at a height that substantially prevents the rinsing solution from entering the first compartment until after the first compartment is almost emptied of the medication solution, and wherein the separation/communication portion is configured to allow the rinsing solution to automatically flow into the first compartment via the communication channel when a pressure in the first compartment becomes negative with respect to a pressure in the second compartment under a siphon effect created by a fluid column height in the infusion line. 2. The bag according to claim 1, wherein the second compartment comprises a narrow area at the top of the bag. 3. The bag according to claim 1, further comprising means for preventing the flow path of the rinsing solution from being sealed completely when the bag flattens. 4. The bag according to claim 3, wherein said means for preventing the flow path of the rinsing solution from being sealed completely comprises a roughening of the surface of at least one of the faces of the bag. 5. The bag as claimed in claim 3, wherein said means for preventing the flow path of the rinsing solution from being sealed completely comprises a channel made by thermoforming. 6. The bag according to claim 1, wherein the bag is flexible. 7. The bag according to claim 1, wherein the first compartment and the second compartment are separated by a substantially vertical wall. 8. The bag according to claim 1, wherein the second compartment has a volume of approximately 10 ml. 9. The bag according to claim 1, wherein the height that substantially prevents the rinsing solution from entering the first compartment until after the first compartment is almost emptied of the medication solution is a location above a fill level of the medication solution in the first compartment. 10. A bag for medical use for infusing medication by gravity, comprising: a first compartment configured to contain a first solution, a second compartment configured to contain a second solution, the second compartment being separate from the first compartment, wherein the first compartment and the second compartment are adjacent to one another, a separation portion that separates the first compartment and the second compartment from each other, a communication channel configured to communicate between the first compartment and the second compartment, the communication channel being disposed at a first end of the bag above the second compartment when the bag is suspended vertically, wherein the communication channel has an inlet side and an outlet side, the inlet side in communication with the second compartment and the outlet side in communication with the first compartment, and wherein the outlet side of the communication channel is disposed at a height that substantially prevents the second solution to be outputted from the outlet side from entering the first compartment until after the first compartment is almost emptied of the first solution, an access port for an infusion line disposed at a second end of the bag that is disposed at a bottom portion of the first compartment when the bag is suspended vertically, the infusion line being in communication with the first compartment, a breakable device in communication with the communication channel and being disposed between the first compartment and the second compartment, wherein the breakable device is configured to prevent communication between the first compartment and the second compartment when intact, and the breakable device is configured to allow communication between the first compartment and the second compartment via the communication channel when broken, and wherein, if the breakable device is broken and a pressure in the first compartment becomes negative with respect to a pressure in the second compartment, the communication channel is configured to automatically allow the second solution to flow into the first compartment and the infusion line. 11. A bag for medical use for infusing medication by gravity, comprising: a first compartment configured to contain a first solution, a second compartment configured to contain a second solution, the second compartment being separate from the first compartment, wherein the first compartment and the second compartment are adjacent to one another, a separation portion that separates the first compartment and the second compartment from each other, a communication channel configured to communicate between the first compartment and the second compartment, the communication channel being disposed at a first end of the bag above the second compartment when the bag is suspended vertically, wherein the communication channel has an inlet side and an outlet side, the inlet side in communication with the second compartment and the outlet side in communication with the first compartment, and wherein the outlet side of the communication channel is disposed at a height that is configured such that the second solution to be outputted from the outlet side will enter the first compartment at a height above a fill level of the first solution, an access port for an infusion line disposed at a second end of the bag that is disposed at a bottom portion of the first compartment when the bag is suspended vertically, the infusion line being in communication with the first compartment, a breakable device in communication with the communication channel and being disposed between the first compartment and the second compartment, wherein the breakable device is configured to prevent communication between the first compartment and the second compartment when intact, and the breakable device is configured to allow communication between the first compartment and the second compartment via the communication channel when broken, and wherein, if the breakable device is broken and a pressure in the first compartment becomes negative with respect to a pressure in the second compartment, the communication channel is configured to automatically allow the second solution to flow into the first compartment and the infusion line. 12. The bag according to claim 11, wherein the height of the output side of the communication channel substantially prevents the second solution to be outputted from the outlet side from entering the first compartment until after the first compartment is almost emptied of the first solution.
