Claim Text:
1. A fluid dispensing system for dispensing one or more fluids from one or more reservoirs towards a dosing device, the dosing device being adapted to dispense the one or more fluids to a patient, the fluid dispensing system comprising a) a reusable interconnection set suited for use with multiple patients, the reusable interconnection set comprising for each reservoir: a first tubing part for establishing a fluid connection from the one or more reservoirs to a corresponding one or more filling chambers of a filling and injection device, each filling chamber being provided for storing an amount of fluid from the corresponding one or more reservoirs; a second tubing part for establishing a fluid connection from each of the filling chambers towards the dosing device; and b) a disposable interconnection line to be renewed with each patient; the disposable interconnection line providing a fluid connection between the reusable interconnection set and the dosing device, and comprising a first and a second tubing part which are releasable connectible to each other in a liquid tight manner, wherein a fluid connection between the first and the second tubing part is established by a one-way valve, wherein each first tubing part of the reusable interconnection set comprises one or more first one-way valves oriented in such a way that in use the amount of fluid is allowed to flow from the one or more reservoirs to the one or more filling chambers but is prevented to flow in the opposite direction; wherein each second tubing part of the reusable interconnection set comprises one or more second one-way valves oriented in such a way that in use the fluid is allowed to flow from the one or more filling chambers towards the dosing device but is prevented to flow in the opposite direction; wherein the fluid dispensing system comprises a first particle filter for preventing particles of a size larger than 0.5 μm from being injected into the patient, the first particle filter being located downstream of the one or more filling chambers within the second tubing part of the reusable interconnection set, and wherein the fluid dispensing system is configured to withstand a fluid pressure up to 2 MPa.
