Abstract

There is here provided a wing-like needle protector which can surely prevent mistaken sticking, and can safely cap a hollow needle. The wing-like needle protector for housing a wing-like needle 1 which comprises a hollow needle 2, a holding cylinder 3 for holding a rear end of the hollow needle 2, and a pair of wing pieces 4, 4 formed integrally with the holding cylinder 3 so as to freely coalesce with each other. The protector comprises a gutter-shaped member 7 for housing the hollow needle 2, the holding cylinder 3 and the coalesced wing pieces 4, 4, and a gripper 8 protruded outward from a bottom surface of the gutter-shaped member 7. The gutter-shaped member 7 has a closed tip 9a of a portion 9 for housing the hollow needle 2, an opened rear end 10a of a portion 10 for housing the holding cylinder 3, and a narrowed area 7a where the holding cylinder 3 is fitted in a bottom portion, and the holding cylinder 3 is engaged with the narrowed area 7a. The narrowed area 7a may be partially provided on the bottom portion of the gutter-shaped member 7. The wing pieces 4, 4 of the gutter-shaped member 7 may be housed in and engaged with a portion 11 for housing the wing pieces 4, 4.

Claims

1. A wing-like needle protector for housing a wing-like needle which comprises a hollow needle, a holding cylinder for holding a rear end of the hollow needle, and a pair of wing pieces formed integrally with the holding cylinder so as to freely coalesce with each other, comprising:

a gutter-shaped member including a portion for housing the hollow needle a portion for housing the holding cylinder and a portion for housing the coalesced wing pieces extended upward of the portion for housing the holding cylinder; and

a gripper protruded outward from a bottom surface of the gutter-shaped member;

wherein the gutter-shaped member has a closed tip of the portion for housing the hollow needle, an opened rear end of the portion for housing the holding cylinder, and a narrowed area where a space between side walls of the gutter-shaped member is narrow so as to fit the holding cylinder in a bottom portion;

the holding cylinder is engaged with the narrowed area; and

the housed wing pieces are replusively engaged with the portion for housing the wing pieces.

2. The wing-like needle protector according to claim 1, wherein the narrowed area is partially provided on the bottom portion of the gutter-shaped member.

3. The wing-like needle protector according to claim 1 or 2, wherein the portion for housing the hollow needle is inclined from the portion for housing the holding cylinder toward the gripper.

4. The wing-like needle protector according to any one of claims 1 to 3, wherein a width of the gripper is narrower than a width of the bottom surface of the gutter-shaped member.
