Summary for Patent: 6,074,372

Title:	Dose setting mechanism and an injection syringe having such a dose setting mechanism
Abstract:	A dose setting mechanism for a drug administration device and an injection syringe having such a dose setting mechanism are provided. The injection syringe has a housing accommodating an ampoule (3) containing medicine sufficient for a number of dosed injections, an injection press button (7), a piston rod (13) for co-operation with a piston in the ampoule (3) when injecting, and a dose setting mechanism comprising a rotatable dose setting element (5) interconnected with the press button. The dose setting mechanism further comprises a dose administration wheel (11) connected with the piston rod (13) and a coupling ring (12) connected with the dose setting element (5) and the press button (7). One of the dose administration wheel (11) and the coupling ring (12) at least partly surrounds the other, and the dose administration wheel (11) and the coupling ring (12) are arranged such that rotation of the dose setting element (5) allows the coupling ring (12) to be rotated in either direction in relation to the dose administration wheel (11), while activation of the press button (7), and thereby rotation of the coupling ring (12), causes the dose administration wheel (11) to be rotated.
