A medical infusion apparatus includes a container for a liquid to be infused, tubing leading from the container to the subject to receive an infusion, a pump for pumping the infusion liquid via the tubing to the subject, and a safety valve connected in the tubing between the pump and the subject. The safety valve is normally closed to prevent free flow of the liquid from the container, but is automatically opened when a predetermined minimum pressure is applied to the liquid by the pump. The safety valve is also manually deformable to open the valve and to permit priming the apparatus.

Appareil pour perfusions comportant un récipient (3) recevant le liquide de perfusion, un tube (4) reliant le récipient au patient perfusé, une pompe (6) transférant le liquide de perfusion vers le patient via le tube et une soupape de sûreté (10) placée dans le tube entre la pompe et le patient. Ladite soupape de sûreté, normalement fermée pour empêcher le liquide de s'écouler du récipient, s'ouvre automatiquement quand une pression prédéterminée est appliquée au liquide par la pompe. La soupape de sûreté est également déformable à la main pour permettre l'amorçage de l'appareil.
