VALLINO, Lisa, American nurse. Co-inventor (with her mother ROZIER) of an aid for use when performing intravenous injections. Lisa had decided the current routine procedure was cumbersome, with a high risk of the needle popping out of the vein. She set about designing an improved system involving a plastic cradle for the needle to sit in during the injection. The device taped easily to the arm and had a smooth groove to accommodate the needle. Patients and staff were all more comfortable about the whole process when their device was in use. Since their 1993 patent grant, many hospitals have introduced the technique as standard routine in-house. They have won many awards for invention and entrepreneurship. Their device is called the IV-House.
