Abstract

A safety device for uncapping and recapping a removable protective sheath of a needle includes a cylindrical elongated enclosure. The cylindrical elongated enclosure includes first and second ends and a diameter of sufficient size for receiving and enclosing the sheath. Retaining structure is disposed at the first end of the cylindrical elongated enclosure for grasping and retaining the sheath within the cylindrical elongated enclosure during uncapping and recapping of a needle. Receiving structure communicates with the first end of the cylindrical elongated enclosure for guiding the needle towards the first end of the cylindrical elongated enclosure during recapping and for guiding the sheath toward the first end of the cylindrical elongated enclosure during uncapping.

Claims

1. A one piece safety device for uncapping and receiving a removable protective sheath of a needle comprising:

an elongated cone-like structure having first and second ends, said first end having a diameter greater than the diameter of said second end and further including sidewalls interconnecting said ends;

said sidewalls being selectively yieldable for grasping and retaining the sheath within said elongated cone-like structure during uncapping and recapping of the needle;

a funnel-shaped member having a small-diameter opening and a large-diameter opening interconnected by arcuate sidewalls, said small-diameter opening thereof communicating with said first end of said elongated cone-like structure and said large diameter opening thereof receiving the sheath during uncapping and receiving the needle during recapping and said arcuate sidewalls guiding the needle and sheath toward said first end of said elongated cone-like structure; and

said elongated cone-like structure and said funnel-shaped member are integrally molded from a resilient member.

2. A one piece safety device for uncapping and receiving a removable protective sheath of a needle comprising:

an elongated cone-like structure having first and second ends, said first end having a diameter greater than the diameter of said second end and further including sidewalls interconnecting said ends;

said sidewalls being selectively yieldable for grasping and retaining the sheath within said elongated cone-like structure during uncapping and recapping of the needle;

a funnel-shaped member having a small-diameter opening and a large-diameter opening interconnected by arcuate sidewalls, said large-diameter opening of said funnel-shaped member being circularly shaped, said small-diameter opening thereof communicating with said first end of said elongated cone-like structure and said large diameter opening thereof receiving the sheath during uncapping and receiving the needle during recapping and said arcuate sidewalls guiding the needle and sheath toward said first end of said elongated cone-like structure; and

said elongated cone-like structure and said funnel-shaped member are integrally molded from a resilient member.

3. A one piece safety device for uncapping and receiving a removable protective sheath of a needle comprising:

an elongated cone-like structure having first and second ends, said first end having a diameter greater than the diameter of said second end and further including sidewalls interconnecting said ends;

said sidewalls being selectively yieldable for grasping and retaining the sheath within said elongated cone-like structure during uncapping and recapping of the needle;

a funnel-shaped member having a small-diameter opening and a large-diameter opening interconnected by arcuate sidewalls, said large-diameter opening of said funnel-shaped member being elliptically shaped, said small-diameter opening thereof communicating with said first end of said elongated cone-like structure and said large diameter opening thereof receiving the sheath during uncapping and receiving the needle during recapping and said arcuate sidewalls guiding the needle and sheath toward said first end of said elongated cone-like structure; and

said elongated cone-like structure and said funnel-shaped member are integrally molded from a resilient member.

4. A one piece safety device for uncapping and receiving a removable protective sheath of a needle comprising:

an elongated cone-like structure having first and second ends, said first end having a diameter greater than the diameter of said second end and further including sidewalls interconnecting said ends;

said sidewalls being selectively yieldable for grasping and retaining the sheath within said elongated cone-like structure during uncapping and recapping of the needle;

a funnel-shaped member having a small-diameter opening and a large-diameter opening interconnected by arcuate sidewalls, said small-diameter opening thereof communicating with said first end of said elongated cone-like structure and said large diameter opening thereof receiving the sheath during uncapping and receiving the needle during recapping and said arcuate sidewalls guiding the needle and sheath toward said first end of said elongated cone-like structure;

said elongated cone-like structure and said funnel-shaped member are integrally molded from a resilient member; and

means disposed on said funnel-shaped member adjacent said large-diameter opening for preventing rotation of the safety device when the safety device is positioned on a flat surface.
