摘要：
A syringe for injecting a fluid, such as a contrast medium for radiological diagnostic imaging, is enhanced by hydrophilic treatment of interior surfaces of the syringe, reducing air bubble attachment to the syringe. Air bubbles that do form or that are drawn into the syringe fail to attach to, or readily release from, the interior surface and can be expelled prior to being used on a patient.
