Abstract

Drop by drop delivery of a liq. into the human or animal body is effected by means of a peristaltic pump in which the delivery tube is pinched, through a protecting medium, between rollers mounted on a motor-driven wheel and a slightly elastic bearing piece having a circular profile. A photocell detector surrounds the drip chamber of the delivery tube and a signal is sent, at the passage of each drop, to the electronic control of the motor driving the pump to give the desired delivery rate. Device is mainly of use in the medical field for all slow injections and can be adapted to all commercial drip feeds.
