Improvements in or relating to patient ventilators

The present invention relates to a delivery tube array which is used to connect a patient to a lung ventilator. A problem arising in the use of such ventilators is that exhaled air cannot be exhausted directly to the atmosphere since a normal outlet valve would also serve to exhaust air delivered on the compression stroke of the ventilator. The invention overcomes this problem by the introduction into a delivery tube array of a relief valve 14, a non-return valve 12 and a bleed-pipe 17 which connects the relief valve to a point up-stream of the non-return valve. Such an arrangement ensures that the relief valve opens only when the pressure within the patient's lungs is greater than the pressure upstream of the non-return valve. ...

VALVES AND TUBES INCLUDING VALVES

A valve () for the sealing cuff () of a tracheal tube has a valve member () urged against a valve seal () by an MRI-safe resilient member () of neoprene or nitrile. The valve includes a two-part actuator () by which the valve member is displaced. Before use, during storage, the valve member is in a closed position with the resilient member relatively relaxed. When the valve is opened for the first time by inserting a syringe or the like, the two-part actuator arrangement is moved forwards to unseat the valve member to allow flow. This causes inclined surfaces () and () on the two parts () and () of the actuator to rotate the forward part slightly. When the syringe is removed to allow the valve to close, the forward part of the actuator latches on a surface () of the housing () in an operational position where the valve is closed. 110-.
