Title: REACCESSIBLE MEDICAL NEEDLE SAFETY DEVICES AND METHODS
Abstract:
A retractable and extendable medical needle protective shield (50, 560, 707) which provides opportunity for accessing and reaccessing medical needle (40) and associated sharpened needle tip (100) and recovering the needle (40) and tip (100) for safety between accesses. The shield (50, 560, 707) includes a needle guide (330, 600, 600') which assures the needle tip (100) is untouched by any part of the shield (50, 560, 707) as the shield (50, 560, 707) is displaced to cover and uncover the needle (40). A releasible latch (372, 374, 656, 660, 810, 812) is provided to guard against inadvertent removal of the protective shield between accesses. An unreleasible latch (410, 648) is also provided to secure the shield (50, 560, 707) relative to the latch (410, 648) preparatory to final disposal. In combination with the protective shield (50, 560, 707), a plurality of adapters are disclosed which provide examples of passively operated, protected access to membrane pierceable fluid sources such as a 'Y' connection site (950) of an IVset line (952), a drug vial (900), a vacuum sample tube (902'), an umbilical cord holder (960) and a hypodermic sit (930).
