First Claim
1. A fluid drug dispenser for dispensing fluid from a plurality of fluid containers comprising:
- (a) a frame;
(b) a mounting assembly movably supported relative to the frame for mounting the plurality of containers;
(c) a fluid conduit associated with the frame for receiving fluid from a selected container;
(d) means for moving the mounting assembly to position a selected container in a position for discharging fluid from a container to the conduit and(e) means for forcing liquid from the selected container into the conduit when the selected container is in the discharging position, said forcing means operable to act upon the selected container to discharge fluid with the mounting assembly and other containers remaining in fixed position relative to the frame, said forcing means comprising a forcing member mounted relative to the frame and movable relative to the frame to engage the selected container; and
(f) means for passage to surround the liquid as the liquid moves from the container into the conduit.

Abstract
A liquid dispenser has a transparent frame which houses a rotatable mounting assembly of a plurality of mounted liquid compressible containers having needle discharge outlets having covering caps to block liquid flow. A control unit can be operated so that the mounting assembly is rotated by a motor secured to the frame, and locked in position by a solenoid powered lock pin mounted to the frame which engages the mounting assembly. When the mounting assembly is locked into discharge position, a selected container needle is aligned with a discharge passage in the frame. Then a motor-driven compression drive unit secured to the frame is operated to move a gear rack forward so that a flange secured to the rack engages the end of the liquid container to drive it forward to cause the container needle to puncture its cover cap and also a diaphragm at the frame discharge passage. After the diaphragm is punctured, the flange compresses the liquid in the container through the container needle through the frame discharge passage. A three-way valve is connected to the frame discharge passage to connect the passage to a catheter extending to a needle inserted in the body of a patient. Another catheter connects the valve to a bag of dextrose. A wheel is mounted to the frame with a link engaged to a handle operating the valve so that a drive ramp attached to the rack rotates the wheel to move the valve handle simultaneously with forward rack movement to allow discharge of the liquid from the frame passage through the catheter extending to the patient. A scale associated with the frame and with the compression drive unit indicates to the operator how much liquid has been discharged through the needle extending into the patient'"'"'s body. The rack can be driven rearward so that the wheel can move the valve handle to position the valve to connect the dextrose bag with the needle in the patient.
