Abstract
Abstract A connector is provided between an I.V. or syringe supply and a Y-tube for feeding liquid medication to a patient. The connector is an integrally formed tube having a recessed needle which is factory mounted into the distal end of the connector. At its proximal end, the tube wall of the connector defines a slot which, when rotated, will engage and form a secure lock with the sidearm portion of the Y-tube. A sterile septum is mounted within the Y-tube, and the needle penetrates the septum during use, thereby maintaining sterility. Also, since the needle is recessed, asccidental needle sticks will be reduced. In another embodiment, the connector tube wall defines an elongate recess, and a slotted closure cap is mounted at the proximal end of the connector. The connector is fitted over the Y-tube so that the cap slot and recess coincide with the junction of the Y-tube sidearm and the Y-tube. When the cap is turned, the slot will move out of coincidence with the recess and the sidearm, causing the connector and Y-tube to lock.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
164 words
A connector assembly for joining a Y-tube and a luer, the Y-tube including an attached sidearm, the assembly comprising: a. a resilient, molded, tubular body providing an elongate sidewall and distal and proximal ports, the luer being connected to the distal port, and to an I.V. source, syringe, and the like, and the Y-tube being connected into the proximal port of the tubular body; b. a recessed needle mounted within the distal port of the tubular body in liquid connection with the luer; and, c. a cut-out area defined on the sidewall, and extending from the proximal port of the tubular body, the cut-out area including i. an alignment portion along which the tubular body slides as it deformably fits along the Y-tube and engages therewith, and ii. a notch area defined by the cut-out area; whereby, the tubular body and Y-tube are locked together by sliding the Y-tube along the alignment portion, and deforming the sidearm of the Y-tube into the notch area.
Claim 2
Dependent Claim
164 words
A connector assembly for joining a Y-tube and a luer, the Y-tube including an attached sidearm, the assembly comprising: a. a resilient, molded, tubular body providing an elongate sidewall and distal and proximal ports, the luer being connected to the distal port, and to an I.V. source, syringe, and the like, and the Y-tube being connected into the proximal port of the tubular body; b. a recessed needle mounted within the distal port of the tubular body in liquid connection with the luer; and, c. a cut-out area defined on the sidewall, and extending from the proximal port of the tubular body, the cut-out area including i. an alignment portion along which the tubular body slides as it deformably fits along the Y-tube and engages therewith, and ii. a notch area defined by the cut-out area; whereby, the tubular body and Y-tube are locked together by sliding the Y-tube along the alignment portion, and deforming the sidearm of the Y-tube into the notch area.
Claim 3
Dependent Claim
14 words
The connector of claim 1, in which the cut-out area is an alignment slot.
Claim 4
Dependent Claim
14 words
The connector of claim 1, in which the cut-out area is an alignment recess.
Claim 5
Dependent Claim
213 words
A connector assembly for joining a Y-tube and a luer, the Y-tube including an attached sidearm, the assembly comprising: a. a resilient, molded, tubular body providing an elongate sidewall and distal and proximal ports, the luer being connected to the distal port, and to an I.V. source, syringe, and the like, and the Y-tube being connected into the proximal port of the tubular body; b. a recessed needle mounted within the distal port of the tubular body in liquid connection with the luer; and, c. a cut-out area defined on the sidewall, and extending from the proximal port of the tubular body, the cut-out area including i. an alignment slot along which the tubular body slides as it moves along the base of the Y-tube sidearm when the tubular body and Y-tube are fitted together; and, d. a shaped portion being defined on the sidewall adjacent the alignment slot, the shaped portion being adapted to engage and lock with the sidearm of the Y-tube when the tubular body is resiliently deformed and rotated with respect to the Y-tube, and to unlock when the tubular body is resiliently deformed as it is rotated with respect to the Y-tube in a reverse manner, the Y-tube and tubular body then being disengaged by sliding them apart.
Claim 6
Dependent Claim
213 words
A connector assembly for joining a Y-tube and a luer, the Y-tube including an attached sidearm, the assembly comprising: a. a resilient, molded, tubular body providing an elongate sidewall and distal and proximal ports, the luer being connected to the distal port, and to an I.V. source, syringe, and the like, and the Y-tube being connected into the proximal port of the tubular body; b. a recessed needle mounted within the distal port of the tubular body in liquid connection with the luer; and, c. a cut-out area defined on the sidewall, and extending from the proximal port of the tubular body, the cut-out area including i. an alignment slot along which the tubular body slides as it moves along the base of the Y-tube sidearm when the tubular body and Y-tube are fitted together; and, d. a shaped portion being defined on the sidewall adjacent the alignment slot, the shaped portion being adapted to engage and lock with the sidearm of the Y-tube when the tubular body is resiliently deformed and rotated with respect to the Y-tube, and to unlock when the tubular body is resiliently deformed as it is rotated with respect to the Y-tube in a reverse manner, the Y-tube and tubular body then being disengaged by sliding them apart.
