Abstract
Indwelling needle composed of a body having a closed end, a needle forming at the tip a sharp edge, a tubular hub retaining the proximal end of the needle and slidable along the main body, a protective cover slidable along the main body and projecting from the main body, and a spring elastically fitted between the body and the protective cover. When a first projection is lifted by actuating a lever provided on the body and retractable along with the protective cover relative to the body, the first projection is housed in a through hole and presses a second projection of the protective cover engaged with a second engaging portion toward the inner circumference, rendering an operative state. The resultant length of indwelling needle in operative state can be modified, inhibiting injury to patient.
