ABSTRACT:
A system is provided for the administration of a medicament, such as insulin, to a patient in small, controlled doses over an extended period in response to a continuously generated force. The force may be maintained continuously on a reservoir of the medicament in intermittent communication with a site in the body of the patient through a flexible and compressible tube. A constrictor about the tube keeps it normally closed except when a separate force is exerted to open the constrictor and permit the medicament to flow through the tube for a predetermined period. Alternatively, the continuously generated force may be applied intermittently to the medicament reservoir through the action of an escapement mechanism.
