Method of injecting fluids from a dual syringe injector system
First Claim
1. A method of injecting fluids into a patient to a region of interest within the patient, the method comprising:
- providing an injector system comprising a first syringe mounted thereon for injecting a first fluid, a second syringe mounted thereon for injecting a second fluid, and a controller for controlling the first syringe and the second syringe;
coupling the first syringe to a first injection site on the patient such that the first syringe is configured to deliver the first fluid to the first injection site;
coupling the second syringe to a second injection site on the patient such that the second syringe is configured to deliver the second fluid to the second injection site;
injecting the first fluid into the first injection site on the patient suitable to transport the first fluid to the region of interest; and
injecting the second fluid into the second injection site on the patient suitable to transport the second fluid to the region of interest.

Abstract
Embodiments of an injector, syringe, syringe interface, syringe adapter, and piston/plunger assembly for an injector (of contrast medium, for example) are described. Preferably, the syringe is adapted to engage a syringe interface mechanism such that the syringe may be connected to an injector without regard to any particular orientation of the syringe to the injector or to the piston/plunger assembly. The injector piston or drive member includes a sensing pin positioned at a forward end thereof to sense contact with the syringe plunger during advancement of the piston or drive member to contact the plunger. The piston can be advanced automatically upon connection of, for example, the syringe to the injector, or piston advance can be automated to occur after operator initiation. The injector may include or be adapted to accommodate two syringes, which for example provide for simultaneous injection of fluid into separate injection sites on a patient.

12. A method of injecting fluids into a patient to a region of interest within the patient, the method comprising:
-
providing an injector system comprising a first syringe mounted thereon for injecting a first fluid, a second syringe mounted thereon for injecting a second fluid, and a controller for controlling the first syringe and the second syringe; selecting one of at least three modes of operation of the injector system using the controller, wherein the at least three modes of operation comprise (a) sequential injection of the first fluid from the first syringe and of the second fluid from the second syringe into a single injection site;
(b) simultaneous injection of the first fluid from the first syringe and the second fluid from the second syringe into a single injection site; and
(c) simultaneous injection of the first fluid from the first syringe and the second fluid from the second syringe into two different injection sites; andperforming an injection procedure based on the selection. - View Dependent Claims (13, 14, 15, 16, 17)
