Abstract
An ergonomic safety vacuum syringe for sampling blood comprises a vacuum, a hollow barrel, a first needle, a second needle, and a press plate. The hollow barrel includes an end surface and a cylindrical side surface, with a trench formed through the end surface. A needle seat is coupled to the trench, and a sliding slit is formed through the end surface and cylindrical side surface. The syringe also comprises a first needle coupled to a reduced inlet disposed on the hollow barrel and the second needle having Z-shaped portion formed between opposing first and second end portions. The first end is received within the reduced inlet, while the second end portion is positioned along a central axis of the hollow barrel. Further, the press plate is positioned within the sliding slit of the hollow barrel.
