Abstract

1,109,175. Automatic feed control. DECCA Ltd. July 26, 1965 [Aug.5, 1964], No. 31863/64. Heading G3R. The passage of each drip in a drip feed apparatus is detected by a photo-cell the output of which is integrated to produce a signal which is compared with a desired drip rate signal so that any difference is effective to correct the rate of drip. As applied to blood transfusion apparatus on a wheeled stand, a glass bottle of blood having an air vent is supported in an inverted position so that blood passes to a dispenser through a filter, a drip chamber having transparent walls, and a tube which is squeezed by a motor operated clamp. Light is reflected backwards and forwards to cover the cross-section of the drip chamber so that drops of blood, however they fall, produce output pulses from a photo-cell which are amplified, squared, and integrated to produce a direct voltage representative of the rate of drip. This voltage is compared with a manually selected voltage representing a desired rate of drip and any error is effective to control a switch and operate the reversible motor which corrects the rate of drip by adjustment of the clamp in the appropriate sense. A drip counter and rate indicator are provided and an alarm may be operated when drip rate or amount of blood in the bottle fall below predetermined values. Control of water drip in a similar manner is referred to.
