Estimating the term…
A syringe interface includes a top opening into which a syringe can be loaded, a first retaining member positioned on one side of the opening and a second retaining member positioned on a second side of the opening. The first retaining member and the second retaining member abut a forward facing abutment surface of a syringe flange on the syringe generally symmetrically. The syringe interface further includes a cradle, at least one engagement member to abut a forward facing abutment surface of a syringe flange, and a carriage slidably disposed within the cradle. The carriage includes a connector to form a releasable connection with a plunger or plunger extension of the syringe and a drive member of the injector. The connector includes a plurality of flexing capture members that flex radially outward to connect to a flange on the rear of the plunger or plunger extension of the syringe when the carriage is moved forward within the syringe interface. The syringe interface may further include a connector on a rear portion thereof to connect to the injector.
A syringe interface for connecting a syringe comprising a flange with a forward facing abutment surface and a plunger movably disposed therein to an injector comprising a drive member, the syringe interface comprising:
A syringe interface for connecting a syringe comprising a flange with a forward facing abutment surface and a plunger movably disposed therein to an injector comprising a drive member, the syringe interface comprising:
A syringe adapter for use with a syringe, the syringe including a radially extending flange with a forward facing abutment surface, the adapter including a top opening into which the syringe can be loaded, a first retaining member positioned on one side of the opening and a second retaining member positioned on a second side of the opening, the first retaining member and the second retaining member abutting the forward facing abutment surface of the syringe flange generally symmetrically.
An injector system comprising a powered injector, the powered injector including at least a first drive member for pressurizing a fluid within a first syringe, a cradle extending forward of a first opening in the injector through which the drive member communicates with the interior of the first syringe, at least a first syringe adapter retention mechanism on a forward end of the cradle, and a first adapter for attaching the first syringe to the injector, the first adapter including a releasable attachment mechanism for releasably attaching the first adapter to the first adapter retention mechanism, the first adapter further including a top opening into which the first syringe can be loaded, a first retaining member positioned on one side of the opening and a second retaining member positioned on a second side of the opening, the first retaining member and the second retaining member abutting the forward facing abutment surface generally symmetrically, each of the first retaining member and the second retaining member includes a flexible, radially inward extending member that flexes radially outward when contacted by the first syringe during loading of the first syringe into the adapter and returns to a radially inward position once the first syringe is loaded within the adapter.
An injector system comprising a powered injector including at least a first drive member for pressurizing a fluid within a first syringe and a second drive member for pressurizing fluid within a second syringe, a cradle extending forward of a first opening in the injector through which the first drive member communicates with the interior of the first syringe and a second opening in the injector through which the second drive member communicates with the interior of the second syringe, a first syringe adapter retention mechanism on a forward end of the cradle, a second syringe adapter retention mechanism on a forward end of the cradle, the injector system further including a first adapter for attaching the first syringe to the injector, and a second adapter for attaching the second syringe to the injector, at least the first adapter including a releasable attachment mechanism for releasably attaching the first adapter to the first adapter retention mechanism, the first adapter including a top opening into which the syringe can be loaded, a first retaining member being positioned on one side of the opening and a second retaining member being positioned on a second side of the opening, the first retaining member and the second retaining member abutting the forward facing abutment surface on the first syringe generally symmetrically, each of the first retaining member and the second retaining member includes a flexible, radially inward extending member that flexes radially outward when contacted by the first syringe during loading of the first syringe into the adapter and returns to a radially inward position once the first syringe is loaded within the adapter.
