A method may include providing a syringe device having (a) a single needle, (b) a first syringe comprising saline with microbubbles, (c) a second syringe comprising a therapeutic compound, and (d) a connector coupling the single needle to the first syringe and to the second syringe. The method may further include guiding the single needle to an injection site of a patient; injecting, with the first syringe, a quantity of saline with microbubbles; confirming a desired position of the single needle, with ultrasound imaging, by identifying the microbubbles in the quantity of saline relative to a tip of the single needle and further relative to one or more anatomical landmarks visible with the ultrasound imaging; and injecting, with the second syringe, the therapeutic compound at the injection site. |
