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 one or more reservoirs and a reusable interconnection set, the reusable interconnection set comprising for each reservoir: - a first tubing part for establishing a fluid connection from the reservoir to a corresponding filling chamber of a filling and injection device, each filling chamber being provided for storing an amount of fluid from the corresponding reservoir and comprising a moving part; - a second tubing part for establishing a fluid connection from each of the filling chambers towards the dosing device; - a first particle filter being located downstream of the one or more filling chambers, in the second tubing part of the reusable interconnection set downstream the filling chambers, so that the first particle filter can be reused for several patients; characterized in that: - the first particle filter is for preventing particles of a size larger than 0.5 μm from being injected into the patient; - the fluid dispensing system is capable of withstanding a fluid pressure up to 8 MPa; - each first tubing part comprises a first one way valve oriented in such a way that in use the fluid is allowed to flow from the reservoir to the filling chamber but is prevented to flow in the opposite direction; - each second tubing part comprises a second one way valve oriented in such a way that in use the fluid is allowed to flow from the filling chamber towards the dosing device but is prevented to flow in the opposite direction; - when the moving part in the filling chamber is moved inwards into the chamber, liquid is drawn from the reservoir through the first tubing part and through the first one way valve that is open while the second one way valve is closed; and - when the moving part in the filling chamber is moved outwards of the chamber, liquid in the filling chamber is ejected through the second one way valve into the second tubing part towards the outlet connector, while the first one way valve is closed. - a first tubing part for establishing a fluid connection from the reservoir to a corresponding filling chamber of a filling and injection device, each filling chamber being provided for storing an amount of fluid from the corresponding reservoir and comprising a moving part; - a second tubing part for establishing a fluid connection from each of the filling chambers towards the dosing device; - a first particle filter being located downstream of the one or more filling chambers, in the second tubing part of the reusable interconnection set downstream the filling chambers, so that the first particle filter can be reused for several patients; - the first particle filter is for preventing particles of a size larger than 0.5 μm from being injected into the patient; - the fluid dispensing system is capable of withstanding a fluid pressure up to 8 MPa; - each first tubing part comprises a first one way valve oriented in such a way that in use the fluid is allowed to flow from the reservoir to the filling chamber but is prevented to flow in the opposite direction; - each second tubing part comprises a second one way valve oriented in such a way that in use the fluid is allowed to flow from the filling chamber towards the dosing device but is prevented to flow in the opposite direction; - when the moving part in the filling chamber is moved inwards into the chamber, liquid is drawn from the reservoir through the first tubing part and through the first one way valve that is open while the second one way valve is closed; and - when the moving part in the filling chamber is moved outwards of the chamber, liquid in the filling chamber is ejected through the second one way valve into the second tubing part towards the outlet connector, while the first one way valve is closed.
