Reciprocating Medical Devices - a Study of a New Safety Device

The study design is a randomized study to directly compare the performance and the outcome of syringe and needle procedures with a standard syringe or the new reciprocating procedure device (RDP), which is a type of safety syringe. Over a 5 year period, 820 subjects who require and assent to a syringe and needle procedure for their usual and customary care will be randomized to either a conventional syringe or the RPD with one arm with and without ultrasound guidance. The RPD is designed to be safer, faster, less painful, and more effective for the patient, and the mechanics of the RPD are intended to provide the physician with better needle control, resulting in less needle trauma to patient tissues, and thus, reduced bleeding and pain for the patient. This clinical trial will address whether the RPD is indeed superior to the conventional syringe for shots, injections, and needle procedures, and whether it is a safer, less painful syringe.
