Claims3
A flow-control device for medicinal products, characterized in that it comprises two or more tubes associated, in parallel, with a common inlet and a common outlet for their connection to the supply line of a substance to be infused, each of the said tubes having a precision gauging element, one of which has a much smaller flow than the other or others, respective tube-closure devices being associated with the tube or tubes carrying the larger-capacity gauging elements, to permit optional opening or closure thereof.
A method of administering medicinal substances, characterized in that, in a single administration device provided with two or more separate tubes for respective gauging elements of different capacities, the passage of the main tube or tubes are closed, permitting the supply of the product in accordance with the smaller-volume gauging element, which can administer a quantity of medicinal substance that is sufficient to observe the possible appearance of adverse effects in the patient, the remaining gauging elements subsequently being opened, if there are no adverse effects, and providing the precise total quantity for the treatment, jointly with the pilot gauging element.
