A miniature syringe pump for continuous administration of drugs and hormones: The Mill Hill infuser.

A miniature syringe pump has been developed for intravenous or subcutaneous infusion of the many drugs and hormones which produce better therapeutic responses when continuously delivered at a controlled rate than by repeated separate injections. The infuser uses disposable plastic syringes and is designed for precise tamper-proof delivery of 2 ml/24 h or 2 ml/8 h with quartz-crystal control, unaffected bt the dose-rate can be precisely determined by prescribing solutions of appropriate strength.
