ABSTRACT:
An intravenous infusion system is provided comprising (a) a mechanical clamp for expelling intravenous infusion liquids from a bag containing liquids; (b) a hollow tube connected to the mechanical clamp; and (c) a hollow needle connected to the hollow tube capable of being inserted into the vein of a patient requiring an intravenous infusion. The mechanical clamp comprises a pair of superposed members hingedly connected at one end thereof, each of the members normally being curved outwardly from the one end and diverging therefrom when in the normally opened position, the members having cooperating locking portions at the distal end, the members being formed of a rigid but resiliently deformable material, each of the members being divided into a plurality of sections by longitudinally extending slit portions, whereby when the bag is enclosed within the clamp and the locking portions are cooperatively engaged, the curvature of the members is reversed and a positive pressure is applied thereto to thereby expel the liquid from the bag.
