ROZIER, Betty, American. The co-inventor (with VALLINO) of an aid for use in intravenous injections. Betty was co-opted by her daughter Lisa who had decided to create an improved way of performing intravenous injections. They developed a smooth cradle that taped easily onto the arm. The needle then rests firmly on the support, it is much safer than other procedures and makes the process easy for patients and staff. Their patent was granted in 1993. Many hospitals have seen fit to use their system routinely. They have awards for both invention and innovation.
