Connector and tubing assembly for use with a syringe
First Claim
Patent Images
1. A syringe assembly comprising:
- a syringe comprising a distal end terminating in a tip, and an externally-threaded portion;
a tubing comprising an end portion with an end flange; and
a connector defining a bore with an internally-threaded portion for cooperating with the externally-threaded portion of the syringe, and comprising a retaining member forming an end of the connector and defining a first opening, and an abutment wall spaced from the retaining member and defining a second opening connecting to the bore, the retaining member and abutment wall defining a slot therebetween for receiving the end flange;
wherein the bore is adapted to receive the syringe distal end such that the syringe tip passes through the second opening before the internally-threaded portion of the bore engages the externally-threaded portion of the syringe.

Abstract
An assembly and a method for connecting a syringe to an injector and a catheter includes a connector adapted to be releasably attached to the syringe. The assembly further includes tubing connected to the connector such that the tubing is in sealed fluid connection with the syringe when the connector is attached to the syringe. The tubing is connected to the connector in a manner to prevent disconnection thereof before and during connection of the connector to the syringe.

10. A method of associating tubing with a syringe comprising:
-
providing a syringe comprising a distal end terminating in a tip and an externally-threaded portion, a tubing comprising an end portion with an end flange, and a connector defining a bore with an internally-threaded portion and comprising a retaining member forming an end of the connector and defining a first opening and an abutment wall spaced from the retaining member and defining a second opening connecting to the bore, the retaining member and abutment wall defining a slot therebetween; and
inserting the syringe distal end into the bore such that the syringe tip passes through the second opening before the internally-threaded portion of the bore engages the externally-threaded portion of the syringe. - View Dependent Claims (11, 12, 13, 14)

15. A method of manufacturing a connector and tubing assembly comprising:
-
molding a connector defining a bore from a first polymeric material having a first melting point;
cooling the connector;
molding an end portion adapted for connection to a tubing at least partially within the connector bore from a second polymeric material having a second melting point that is less than the first melting point; and
cooling the end portion, such that the portion of the end portion molded within the connector bore shrinks from contact with the connector such that the end portion is rotatable relative to the connector. - View Dependent Claims (16, 17, 18, 19, 20)
