Tube connector with security means

Claim 2

Medical fluid connection means for releasably connecting a tracheal tube adapted to be intubated in a patient to a fluid coupling adapter of gas supply equipment having slip-fit connection means comprising a single-piece connector having a bore therethrough and with the distal end thereof connectible with the proximal end of a tracheal tube to connect the tube in fluid communication with said bore, said connector having an integral slip-fit coupler at the proximal end thereof connectible with the slip-fit connection means for connecting the adapter in fluid communication with said bore and the tracheal tube, and radially extending flange means having a pair of diametrically disposed slots extending inwardly from the radially outer periphery thereof, each of said slots having a radially outer entrance portion of less width than an inner portion thereof, and an elastic security member having diametrically opposed free ends and an integral intermediate portion between said opposed free ends, said intermediate portion being capable in use of extending at least partially around a part of an adapter, said intermediate portion including a closed loop portion forming an opening adapted to encircle a portion of an adapter, and a pair of arms integral with and extending diametrically in opposite directions from said loop portion and integrally connected respectively to said free ends, each of said arms having a portion thereof movable into one of said slots and having a width greater than the width of said entrance portion of the slot, each of said free ends having a width greater than the width of said inner portion of each of said slots and the width of said portions of said arms and engageable with said flange means on the distal side thereof to hold the ends of the elastic member in place whereby said elastic member resiliently resists the fluid coupling adapter and said connector from moving apart when in use.

Claim 3

The connection means of claim 1 wherein said closed loop portion and said opening are generally circular for encircling a tubular portion of a fluid coupling adapter when used, and the width of said arms and said loop portion are approximately the same.

Claim 4

A tracheal tube assembly adapted to be connected to a fluid coupling adapter of gas supply equipment having slip-fit connection means comprising a tracheal tube having a distal end adapted to be inserted into a trachea of a patient, a single-piece connector having a bore therethrough and having the distal end thereof connected with the proximal end of said tracheal tube to connect said tube in fluid communication with said bore, a slip-fit coupler at the opposite end of the connector connectable with the slip-fit connection means for connecting the adapter in fluid communication with said bore and said tracheal tube, and radially extending flange means having a pair of diametrically disposed slots extending inwardly from the radially outer periphery thereof, each of said slots having an outer entrance portion of less width than an inner portion thereof, and an elastic security member having diametrically opposed free ends and an integral intermediate portion between said opposed free ends, said intermediate portion being capable in use of engaging and extending at least partially around a part of an adapter, said intermediate portion including a generally central closed loop portion forming an opening adapted to encircle a part of an adapter, and a pair of arms integral with and extending diametrically in opposite directions from said loop portion and integrally connected respectively to said free ends, each of said arms having a portion thereof movable into one of said slots and having a width greater than the width of said entrance portion of the slot, each of said free ends having a width greater than the width of said inner portion of each of said slots and the width of said portions of said arms and engageable with said flange means on the distal side thereof to hold the ends of the elastic member in place whereby said elastic member tends to resiliently urge the adapter and said connector toward each other in use.

Claim 5

A tracheal tube assembly adapted to be connected to a fluid coupling adapter of gas supply equipment having slip-fit connection means comprising a tracheal tube having a distal end adapted to be inserted into a trachea of a patient, a single-piece connector having a bore therethrough and having the distal end thereof connected with the proximal end of said tracheal tube to connect said tube in fluid communication with said bore, a slip-fit coupler at the opposite end of the connector connectable with the slip-fit connection means for connecting the adapter in fluid communication with said bore and said tracheal tube, and radially extending flange means having a pair of diametrically disposed slots extending inwardly from the radially outer periphery thereof, each of said slots having an outer entrance portion of less width than an inner portion thereof, and an elastic security member having diametrically opposed free ends and an integral intermediate portion between said opposed free ends, said intermediate portion being capable in use of engaging and extending at least partially around a part of an adapter, said intermediate portion including a generally central closed loop portion forming an opening adapted to encircle a part of an adapter, and a pair of arms integral with and extending diametrically in opposite directions from said loop portion and integrally connected respectively to said free ends, each of said arms having a portion thereof movable into one of said slots and having a width greater than the width of said entrance portion of the slot, each of said free ends having a width greater than the width of said inner portion of each of said slots and the width of said portions of said arms and engageable with said flange means on the distal side thereof to hold the ends of the elastic member in place whereby said elastic member tends to resiliently urge the adapter and said connector toward each other in use.
