Abstract
In an intravenous needle and needle holder assembly, the needle is attached to an inner case, through which intravenous fluid is supplied, by a length of flexible tubing. An outer case is provided which surrounds the tubing during insertion of the needle into a patient's vein, so as to rigidify the needle during such insertion. After insertion, the outer case can be removed from at least a part of the flexible tubing so that the tubing provides a flexible connection between the inner case and the needle useful during administration of intravenous fluid.
