Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
72 words
In a tracheostomy tube strap having a portion adapted for retention on a patient and an integral, resilient tubular connector having a ferrule on the outer surface thereof for operable engagement with respiratory apparatus, the improvement which comprises a non-resilient annular member contained within the wall of the tubular connector at a position intermediate the ferrule and the distal end of the connector, whereby said annular member prevents removal of the ferrule.
Claim 2
Dependent Claim
72 words
In a tracheostomy tube strap having a portion adapted for retention on a patient and an integral, resilient tubular connector having a ferrule on the outer surface thereof for operable engagement with respiratory apparatus, the improvement which comprises a non-resilient annular member contained within the wall of the tubular connector at a position intermediate the ferrule and the distal end of the connector, whereby said annular member prevents removal of the ferrule.
Claim 3
Dependent Claim
86 words
A tracheostomy tube connector unit comprising a substantially flat strap portion adapted for retention on a patient and having an opening therein, a hollow, resilient, tubular connector joined to said strap over said opening, said tubular connector having a continuous circumferential first groove on the outer surface thereof and a continuous second groove in the distal end thereof, a ferrule positioned within said first groove for operable engagement with respiratory apparatus and a non-resilient annular ring effectively preventing removal of said ferrule during respiratory care operations.
Claim 4
Dependent Claim
86 words
A tracheostomy tube connector unit comprising a substantially flat strap portion adapted for retention on a patient and having an opening therein, a hollow, resilient, tubular connector joined to said strap over said opening, said tubular connector having a continuous circumferential first groove on the outer surface thereof and a continuous second groove in the distal end thereof, a ferrule positioned within said first groove for operable engagement with respiratory apparatus and a non-resilient annular ring effectively preventing removal of said ferrule during respiratory care operations.
Claim 5
Dependent Claim
26 words
A tracheostomy tube connector unit as in claim 2 wherein the depth of said first groove is substantially equal to the wall thickness of said ferrule.
Claim 6
Dependent Claim
26 words
A tracheostomy tube connector unit as in claim 3 wherein the outside diameter of said annular ring is greater than the inside diameter of said ferrule.
