Abstract
A medical transfer set includes flexible tubing and a swabbable valve operatively coupled to an end of the flexible tubing, the swabbable valve including a body having opposing distal and proximal ends and defining an interior, a flexible plug arranged within the interior and providing an inner flow path extending between opposing distal and proximal ends of the flexible plug, and a universal proximal connector provided at the proximal end of the body and including a stem and a head extending from the stem. The universal proximal connector is configured to be interconnected and used with both a luer nut syringe and a luer lock syringe.
Claims20
A medical transfer set, comprising:
- a piercing spike;
- flexible tubing having opposing first and second ends, the piercing spike being operatively coupled to the first end;
- and
- a swabbable valve operatively coupled to the second end and including:
- a body having opposing distal and proximal ends and defining an interior;
- a flexible plug arranged within the interior and providing an inner flow path extending between opposing distal and proximal ends of the flexible plug;
- and
- a universal proximal connector provided at the proximal end of the body and including a stem and a head extending from the stem;
- wherein the universal proximal connector is configured to be interconnected and used with both:
- a luer nut syringe having a luer nut interface providing a first pin member and a luer nut threadably and rotatably attached to the first pin member, the luer nut defining a connector aperture sized to laterally receive the universal proximal connector, wherein, when the head and the stem are received within the connector aperture, rotating the luer nut draws the swabbable valve toward the first pin member to advance a distal tip of the first pin member into the inner flow path;
- and
- a luer lock syringe having a luer lock interface providing a luer lock and a second pin member extending within and concentric with the luer lock, wherein threading is defined on an inner surface of the luer lock, and the head is sized to be received within the luer lock and engageable with the threading such that rotating the swabbable valve relative to the luer lock syringe advances a distal tip of the second pin member into the inner flow path.

A swabbable valve for a medical transfer set, comprising:
- a body having opposing distal and proximal ends and defining an interior;
- a flexible plug arranged within the interior and providing an inner flow path extending between opposing distal and proximal ends of the flexible plug;
- and
- a universal proximal connector provided at the proximal end of the body and including a stem and a head extending from the stem,
- wherein the universal proximal connector is configured to be interconnected and used with both:
- a luer nut syringe having a luer nut interface providing a first pin member and a luer nut threadably and rotatably attached to the first pin member, the luer nut defining a connector aperture sized to laterally receive the universal proximal connector, wherein, when the head and the stem are received within the connector aperture, rotating the luer nut draws the swabbable valve toward the first pin member to advance a distal tip of the first pin member into the inner flow path;
- and
- a luer lock syringe having a luer lock interface providing a luer lock and a second pin member extending within and concentric with the luer lock, wherein threading is defined on an inner surface of the luer lock, and the head is sized to be received within the luer lock and engageable with the threading such that rotating the swabbable valve relative to the luer lock syringe advances a distal tip of the second pin member into the inner flow path.

A method of transitioning a medical transfer set between syringes, comprising:
- positioning the medical transfer set adjacent a luer nut syringe, the medical transfer set including a swabbable valve operatively coupled to flexible tubing and including:
- a body having opposing distal and proximal ends and defining an interior;
- a flexible plug arranged within the interior and providing an inner flow path extending between opposing distal and proximal ends of the flexible plug;
- and
- a universal proximal connector provided at the proximal end of the body and including a stem and a head extending from the stem;
- operatively coupling the medical transfer set to a luer nut interface of the luer nut syringe, the luer nut interface including a first pin member and a luer nut threadably and rotatably attached to the first pin member, wherein operatively coupling the medical transfer set to the luer nut interface includes:
- laterally receiving the head and the stem within the connector aperture;
- and
- rotating the luer nut and thereby drawing the swabbable valve toward the first pin member and advancing a distal tip of the first pin member into the inner flow path;
- disconnecting the medical transfer set from the luer nut syringe;
- operatively coupling the medical transfer set to a luer lock interface of a luer lock syringe, the luer lock interface providing a luer lock and a second pin member extending within and concentric with the luer lock, wherein operatively coupling the medical transfer set to the luer lock interface includes:
- receiving the head within the luer lock and engaging the head with threading defined on an inner surface of the luer lock;
- and
- rotating the swabbable valve relative to the luer lock syringe and thereby advancing a distal tip of the second pin member into the inner flow path.
