Abstract:
An infusion device lateral to the ventilation duct for administering toxic fluid comprising:an insertion portion for connecting via a proximal end thereof to an infusion bag when in an installed condition, said insertion portion having a flow duct connectable to said infusion bag when in an installed condition via a free, proximal outlet end of the flow duct, and a separate ventilation duct connectable to said infusion bag when in an installed condition via a free, proximal inlet end of the ventilation duct, the insertion portion being structured to provide that both the free end of the flow duct and the free end of the ventilation duct, when in an installed condition, are in fluid contact with an interior of the infusion bag simultaneously and independently of each other, the ventilation duct and the flow duct being permanently fixed in relation to each other; the flow duct having an outlet at an opposite, distal end thereof; and, the ventilating duct being constructed to provide, when in the installed condition, fluid communication between the infusion bag and an exterior of said infusion device, an opposite, distal end of the ventilation duct opening to a connection arranged on a side of said infusion device for supplying said toxic fluid, wherein said connection is provided with at least one airtight, self-sealing membrane that is penetrable by an injection needle, which membrane automatically reseals upon withdrawal of the injection needle therefrom.
