Abstract
Methods and devices for use and handling of intravenous and/or subcutaneous needles, and, more particularly, to safety devices for shielding needles or other sharp articles or devices that present a safety hazard are disclosed. In an embodiment, a needle protective sheath can include a top wall, a bottom wall, and a pair of side walls joining the top and bottom walls. A finger shield extends from the top wall at a front opening of the sheath and is attached to the top wall by a hinge portion. The finger shield can be rotated about the hinge portion to block the front opening so as to secure a needle within the sheath.
Claims20
A needle protective sheath, comprising:
- a top wall;
- a bottom wall;
- and
- a pair of side walls joining the top wall and the bottom wall, wherein
- the top wall and the bottom wall define a front opening and a rear opening at opposite ends of the needle protective sheath,
- a finger shield extends from the top wall at the front opening,
- the finger shield is attached to the top wall by a hinge portion,
- the finger shield is constructed to rotate about the hinge portion,
- the finger shield is configured to block the front opening when the finger shield is rotated about the hinge portion from an open position to a closed position so as to secure a needle within the needle protective sheath when the finger shield is in the closed position, and
- the finger shield is configured to lock into the closed position once the finger shield has been rotated to the closed position.
A cannulation device, comprising:
- a needle protective sheath, including
- a top wall;
- a bottom wall;
- and
- a pair of side walls joining the top wall and the bottom wall, wherein
- the top wall and the bottom wall define a front opening and a rear opening at opposite ends of the needle protective sheath,
- a finger shield extends from the top wall at the front opening,
- the finger shield is attached to the top wall by a hinge portion,
- the finger shield is constructed to rotate about the hinge portion,
- the finger shield is configured to block the front opening when the finger shield is rotated about the hinge portion from an open position to a closed position so as to secure a needle within the needle protective sheath when the finger shield is in the closed position, and
- the finger shield is configured to lock into the closed position once the finger shield has been rotated to the closed position;
- and
- a needle connected to a tube, the tube passing through the front opening and the rear opening when the finger shield is in the closed position, and the needle being contained within the needle protective sheath when the finger shield is in the closed position.
