A compact, patient controlled fluid dispenser for use in controllably dispensing fluid medicament at a selected uniform rate. The device is of an all mechanical construction and is ideally suited for the reliable patient administration of pain killing drugs in the home care environment. To positively regulate the patient administration of the medicament, the intervals at which a selected medicament can be administered, as well as the volume of the dose of the medicament to be administered, is preset by the treating physician and, once set, cannot be altered by the patient. More particularly, the device setting can only be operated by a small physician's key that remains in the possession and control of the treating physician or health care worker.
