An infusion set for administering an infusion fluid to a patient. The infusion set includes a fluid container for the infusion fluid, an injection needle for injecting the infusion fluid into the patient's body, a flow regulator having a housing with an inlet, which communicates with the fluid container, and an outlet, which communicates with the injection needle via a fluid duct, at least one fluid chamber in the housing, at least one floater placed in the at least one fluid chamber. Moreover the infusion set comprises an inlet throttle and/or closure valve that includes a valve seat formed on the housing at the inlet and a corresponding inlet valve body connected with the floater at an axial distance from the at least one floater by at least one connector, an air gap formed between the inlet valve body and the floater, and at least one opening in the at least one connector for allowing fluid communication between the inlet throttle and/or closure valve and the housing. The flow regulator automatically regulates, with optimal comfort and safety for the patient, the flow of fluid by means of a simple and inexpensive construction allowing the nurses to watch and evaluate the progress of the infusion process through the window. |
