PROTECTOR FOR INDWELLING NEEDLE HAVING WINGS

摘要

To provide a protector for a indwelling needle having wings which requires only a simple operation to house a indwelling needle having wings in a protector main body and can house a hollow needle thereof with reliability. In a cylindrical outer sleeve 2 for housing a indwelling needle having wings 5 with wings 6 thereof uncovered, there are formed a pair of slits 7a, 7b for guiding the wings 6 in a housing direction and holding the wings 6 at the proximal end thereof. The slits extend parallel to each other and are longer than a hollow needle 5b. There are provided a pair of projections 8a that are provided across the slits 7a, 7b and can resiliently pivot toward the inside of the outer sleeve 2. One end of each projection 8a which is to abut against the wing 6 moving in the housing direction along the slit 7a, 7b constitutes a slanted edge that obliquely traverses the slit 7a, 7b, and the other end of each projection 8a which is to abut against the wing 6 located at the proximal end of the slit 7a, 7b constitutes an engagement edge that locks the wing 6 and restricts movement thereof in a removal direction.
