Abstract
A method and device for filling a syringe with a chemical solution such as a contrast agent is disclosed. The device has a cylinder holder, a piston holder, a driving mechanism to move the piston holder relative to the cylinder holder, a keyboard to input test conditions, and a computer. Based on the test conditions, the computer calculates the volume of the chemical solution necessary for a patient. The piston holder is allowed to aspirate the precise volume necessary for the patient from a bottle where the chemical solution is stored. Thus the correct and necessary volume of the chemical solution is transferred from the bottle to the syringe, which minimizes the waste of the chemical solution.
