Abstract

A gravity, dpip-feed is claimed for liq. perfusion or injection into a patient's body via a flexible tube from a supply flask above the body. The tube passes through a first valve which normally closes the tube by compressing it between one fixed and one movable jaw, but is periodically opened by releasing the movable jaw. A second valve, between the first valve and the injection point, again has fixed and movable jaws which can at least partly, and pref. completely close the tube by compression. The two valves pref. open simultaneously. The second valve closes the tube completely, but does not start to close until the first valve is completely closed. The movable jaw of the first valve is pref. tapered to a narrow, leading edge, the movable jaw of the second valve pref. has a comparatively large area or jaw face. Both movable jaws are pref. fixed on a single, mobile carrier frame actuated by an electromagnet. The electromagnet is pref. of the twin-pole type and is used to pivot the carrier frame on which the mobile jaws are mounted. Used for controlling the rate of drip feed e.g. in gynaecology and cardiology cases. Combines the precision of the peristaltic pump with the cheapness of gravity drip feed. No air can enter the patient via the needle. The drip base can be precisely and positively controlled, even below 20 drips per minute.
