Syringe adapter with a driver for agitation of the syringe content
First Claim
1. An adapter connectable with an automatic syringe pump for a hand-held syringe and a hand-held syringe, the syringe including an elongate syringe body containing contents to be dispensed, said adapter comprisinga syringe driver for rotating the syringe body;
- an adapter body receivable by the syringe pump;
a syringe retainer for retaining a hand-held syringe;
an elongate guide piston, wherein said adapter body defines a guide piston opening andan elongate guide piston passageway in communication with said guide piston opening for slideably receiving said guide piston moving between a first and a second position;
an extension arm supported by said guide piston, said extension arm including a free end in movable spaced registry with said syringe retainer;
a dispense rod supported by said extension arm, said dispense rod engaging a dispensing member of the hand-held syringe so as to cause the contents to be dispensed as said dispense rod is moved relative to said syringe retainer, wherein said dispense rod is rotateably mounted to said extension arm so as to enable said dispense rod to rotate with the hand-held syringe.

Abstract
Administration by injection or infusion to patients of an injectable liquid for diagnostic or therapeutic purposes is provided by a syringe adapter connectable with an automatic syringe pump and a syringe containing contents to be dispensed. The syringe adapter includes an adapter body receivable by the syringe pump, a syringe retainer for retaining the syringe, and a syringe driver for agitating the contents of the syringe. More particularly the invention relates to an adapter connectable with a syringe pump and methods for delivery of an injectable liquid using such adapter. By connecting an adapter according to the invention to a syringe and a syringe pump, rotation of the syringe is achieved and homogeneity of the injectable is preserved. Particularly, the injectable liquid is an ultrasound contrast agent comprising an aqueous dispersion of gas-filled microbubbles or of particulate matter.
