An administration set which is suitable for giving an infusion of liquid to a patient by gravity flow from a container of liquid through the set and to the patient is described. The administration set comprises a fluid reservoir (30), a flow regulator (40) and a barostat device (31) which compensates for changes in fluid pressure during the infusion. The fluid reservoir (30) is positioned upstream of the flow regulator (40) and the barostat device (31) is downstream of the flow regulator (40). In a preferred embodiment a piercing needle (35) connects with a closable tube (48) and injection site (36) which enter the main body of the reservoir (30) by a secure seal. A drip-chamber (42) may be placed in the infusion tube (43). |
