ABSTRACT:
An antidisconnect device is provided to prevent the inadvertent separation of medical fittings or connectors normally provided on the external end of a patient connected medical device such as an endotracheal or tracheostomy tube. The antidisconnect device basically comprises an annular ring having an internal diameter adapted to slip in close engagement over the normal outside diameter of the medical tubing. When assembled, the medical tubing is forced onto the tapered endotracheal tube connector thus distorting and enlarging the outside diameter of the medical tubing to a diameter larger than the internal diameter of the antidisconnect device. The antidisconnect device can then be moved toward the endotracheal tube tapered connector and can be forcefully held in position against the expanded diameter of the medical tubing. A strap extends from the annular ring to encircle any fitting or connector extending from the medical tubing to the patient and the distal end of the strap is affixed to the annular ring. Thus, any connector or fitting is encircled by the strap and disengagement by loosening of the tapered connections is prevented.
