Abstract

A connector assembly may include a body and a fluid fitting, the fluid fitting configured for releasably engaging a syringe nozzle, at least one deflectable locking arm connected to the body and radially deflectable relative to the distal end, the proximal end of the at least one deflectable locking arm configured for deflecting in a radial direction relative to the distal end to releasably engage the syringe nozzle, and at least one locking element disposed on the at least one deflectable locking arm, the at least one locking element movable with movement of the at least one deflectable locking arm between a first position where the at least one locking element is released from an engagement portion of the syringe nozzle and a second position where the at least one locking element is engaged with the engagement portion of the syringe nozzle.

First claim

1 . A connector assembly comprising:
a body having a proximal end and a distal end spaced apart along a longitudinal axis and a fluid fitting at the proximal end of the body, wherein the fluid fitting is configured for releasably engaging a syringe nozzle; a passageway defined by and extending through the body and the fluid fitting; at least one deflectable locking arm having a distal end connected to the body and a proximal end, wherein the proximal end of the at least one deflectable locking arm is configured for deflecting in a radial direction relative to the distal end to releasably engage an engagement portion of the syringe nozzle; and at least one locking element disposed on at least a portion of the at least one deflectable locking arm, the at least one locking element movable with movement of the at least one deflectable locking arm between a first position where the at least one locking element is disengaged from the engagement portion of the syringe nozzle and a second position where the at least one locking element is engaged with the engagement portion of the syringe nozzle and the passageway is in fluid communication with the syringe nozzle.

2 . The connector assembly of claim 1 , further comprising at least one releasing tab provided on the at least one deflectable locking arm to assist in deflecting the proximal end of the at least one deflectable locking arm in the radial direction relative to the distal end of the at least one deflectable locking arm.

3 . The connector assembly of claim 1 , further comprising at least one gripping tab on the body for gripping the connector assembly.

4 . The connector assembly of claim 1 , wherein the at least one deflectable locking arm comprises two deflectable locking arms provided on opposing sides of the longitudinal axis of the body, and
wherein the proximal end of each of the two deflectable locking arms are movable apart from one another to move the at least one locking element of each of the two deflectable locking arms radially outward relative to the longitudinal axis of the body.

5 . The connector assembly of claim 1 , further comprising a protective skirt provided at the proximal end of the at least one deflectable locking arm,
wherein the protective skirt is shaped to surround at least a portion of the syringe nozzle when the connector assembly is engaged with the syringe nozzle.

6 . The connector assembly of claim 1 , further comprising an opposing fitting provided at the distal end of the body for connecting to tubing of a tube set.

7 . The connector assembly of claim 1 , wherein the at least one deflectable locking arm is deflected radially outward by a lip on the engagement portion of the syringe nozzle upon pressing the connector assembly against the lip.

8 . The connector assembly of claim 1 , further comprising a piercing member extending from a distal end of the body and in fluid communication with the passageway.

9 . The connector assembly of claim 1 , further comprising a tubing manifold provided on a distal end of the connector assembly.

10 . The connector assembly of claim 1 , wherein the at least one deflectable locking arm disengages the engagement portion of the syringe nozzle by rotation of the connector assembly about the longitudinal axis of the syringe.

11 . A syringe and connector system for use in a medical injection procedure, the syringe and connector system comprising:
a syringe having a proximal end and a distal end with a syringe nozzle on the distal end; and a connector assembly configured for releasably engaging the syringe nozzle, the connector assembly comprising:
a body having a proximal end and a distal end spaced apparat along a longitudinal axis and a fluid fitting at the proximal end of the body, wherein the fluid fitting is configured for releasably engaging the syringe nozzle;
a passageway defined by and extending through the body and the fluid fitting;
at least one deflectable locking arm having a distal end connected to the body and a proximal end, wherein the proximal end of the at least one deflectable locking arm is configured for deflecting in a radial direction relative to the distal end to releasably engage an engagement portion of the syringe nozzle; and
at least one locking element disposed on at least a portion of the at least one deflectable locking arm, the at least one locking element movable with movement of the at least one deflectable locking arm between a first position where the at least one locking element is disengaged from the engagement portion of the syringe nozzle and a second position where the at least one locking element is engaged with the engagement portion of the syringe nozzle and the passageway is in fluid communication with the syringe nozzle.

12 . The syringe and connector system of claim 11 , further comprising at least one releasing tab provided on the at least one deflectable locking arm to assist in deflecting the proximal end of the at least one deflectable locking arm in the radial direction relative to the distal end.

13 . The syringe and connector system of claim 11 , further comprising at least one gripping tab on the body for gripping the connector assembly.

14 . The syringe and connector system of claim 11 , wherein the at least one deflectable locking arm comprises two deflectable locking arms provided on opposing sides of the longitudinal axis of the body, and
wherein the proximal end of each of the two deflectable locking arms are movable apart from one another to move the at least one locking element of each of the two deflectable locking arms radially outward relative to the longitudinal axis of the body.

15 . The syringe and connector system of claim 11 , further comprising a protective skirt provided on at the proximal end of the at least one deflectable locking arm,
wherein the protective skirt is shaped to surround at least a portion of the syringe nozzle when the connector assembly is engaged with the syringe nozzle.

16 . The syringe and connector system of claim 11 , further comprising an opposing fitting provided at the distal end of the body for connecting to tubing of a tube set.

17 . The syringe and connector system of claim 11 , wherein the at least one deflectable locking arm is deflected radially outward by a lip on the engagement portion of the syringe nozzle upon pressing the connector assembly against the lip.

18 . The syringe and connector system of claim 11 , wherein the syringe nozzle comprises:
an inner member having a fluid channel in fluid communication with an interior of the syringe; an outer annular skirt spaced apart from the inner member by an annular space; and wherein the engagement portion of the syringe nozzle is located on a radially outer surface of the outer annular skirt.

19 . The syringe and connector system of claim 11 , further comprising a tubing manifold provided on a distal end of the connector assembly.

20 . The syringe and connector system of claim 11 , wherein the at least one deflectable locking arm disengages the engagement portion of the syringe nozzle by rotation of the connector assembly about the longitudinal axis of the syringe.
