Abstract

An improved injection device is operated in a manual mode in which it delivers a liquid drug to a patient at a rate determined all the time by a control member, and a cruise control mode in which the preselected rate is maintained by the controller after the control member is released by a clinician. The control member may be used to select one of two liquid delivery rates, or alternatively a delivery rate may be selected which may have values between an upper and a lower limits. If the device is operated in the cruise control mode, an override switch must be activated to reset the rate.
