Abstract
A medico-surgical suction system has a container with an outlet connected to a vacuum pump and an inlet connected to a suction catheter via a dual-lumen tube assembly one end of which is connected to the container and the other end of which is has a suction control and a coupling for the catheter. A valve located in the outlet of the container is connected to the suction control via a minor lumen of the tube. A side lumen enables the vacuum pump to apply reduced pressure to one end of the valve which holds the valve off against the action of a spring. Actuation of the suction control allows air to flow to the valve via the minor lumen so that the effect of the reduced pressure is overcome and the spring opens the valve.
