US 4,307,903 A · Antidisconnect harness for medical connections

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.

Dependent claims

An antidisconnect device to prevent the disconnection between various tapered fitting connectors adapted to be forced into a medical tubing creating a circumferentially continuous end of increased diameter thereof and a device administering gas to a patient through the tubing, said device comprising:

a semi-flexible annular ring of predetermined inside diameter, said inside diameter being approximately the same dimension as the outside diameter of said tubing, such that said annular ring slides tightly over said tubing and which inside diameter is smaller than the increased diameter end of said tubing, said annular ring being sufficiently flexible to flex and distort as it is slid against the increased diameter end of said tubing to form a gas tight fit between said tubing and the tapered fitting connector;
strap means having one end integrally molded to said ring and being of predetermined length to encircle the connectors joined to said tubing;
and
securing means to secure the other end of said strap means to said annular ring, said securing means adapted to secure said strap at a plurality of positions along said strap wherein said strap can tightly encircle said connectors and hold said connectors from moving away from said annular ring, thus preventing disconnection thereof.
