Abstract: A device for protecting a ventilated patient from the adverse consequences of disconnection within a ventilator circuit can be used within ventilator circuits found in either the bedside vent environment or a surgical setting requiring anesthesia. In a bedside vent environment, this device secures joints in the circuit from the proximal end of the wye to the distal end of the in-line suction catheter tubing. In particular, between these two ends, there might be a series of joints created by gas measurement sensors, heated moisture exchangers, and treatment delivery adapters. The inventive device described herein is capable of securing all these joint combinations as well. In a surgical setting, the device secures joints in the circuit from the proximal end of the wye to the distal end of the “elbow” connected to the artificial airway.
