Medicine delivery system

摘要

MEDICINE DELIVERY SYSTEM An injection assembly (10) for injecting medicine. The assembly (10) includes a selectively collapsible elastomeric bulb (12) having a hollow interior and an outlet (20). The bulb (12) is collapsible from an expanded configuration in which the hollow interior has an expanded volume to a collapsed configuration in which the hollow interior has a collapsed volume that is smaller than the expanded volume. The assembly (10) includes a tube (14) having a proximal end (22) connected to bulb (12), a distal end (24), and an interior passage (26) in fluid communication with the outlet (20) of the bulb (12). The assembly (10) includes a needle (16) connected to the distal end (24) of the tube (14) having a sharp distal end. The needle (16) has an interior passage in fluid communication with the interior passage (26) of the tube (14) for delivering medicine from the hollow interior of the bulb (12) when the bulb (12) is compressed and drawing fluid through the needle (16) toward the bulb (12) when the bulb (12) expands. 6175690 1:LKM ':1-4 0o - U '-4D
