Safety Needle Guard
First Claim
1. A needle guard, comprising:
- a binding plate defining a multi-slot aperture, the multi-slot aperture adapted to receive a needle cannula therethrough;
a biasing member biasing the needle cannula within the multi-slot aperture; and
a sensing arm connected to the binding plate adapted to contact a portion of the needle cannula, and positionable for restricting movement of the needle cannula.

Abstract
A needle guard is disclosed. The needle guard includes a binding plate defining a multi-slot aperture adapted to receive a needle cannula therethrough. The needle guard also includes a biasing member for biasing the needle cannula within the multi-slot aperture, and a sensing arm connected to the binding plate. The sensing arm is adapted to contact a portion of the needle cannula, and is positionable for restricting movement of the needle cannula. The multi-slot aperture may include a first region having a first dimension, a second region having a second dimension, and optionally, a third region having a third dimension with the third dimension being smaller than the second dimension and the second dimension being smaller than the first dimension.

11. A needle guard, comprising:
-
a housing, defining an interior, and having a first port and a second port extending therethrough and aligned along an axis of the housing; and a locking mechanism disposed within the interior of the housing, the locking mechanism comprising; a binding plate defining a multi-slot aperture, at least a portion of the multi-slot aperture aligned with the first port and the second port along the axis of the housing, wherein the first port, the second port, and the multi-slot aperture are adapted to receive a needle cannula therethrough, a biasing member for biasing the needle cannula within the aperture, and a sensing arm connected to the binding plate adapted to contact the needle cannula, and positionable for restricting movement of the needle cannula. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A device, comprising:
-
a needle cannula having a cannula tip; a housing disposed about a portion of the needle cannula, defining an interior, and having a first port and a second port extending therethrough and aligned along an axis of the housing; and a locking mechanism disposed within the interior of the housing, the locking mechanism comprising; a binding plate defining a multi-slot aperture, at least a portion of the multi-slot aperture aligned with the first port and the second port along the axis of the housing, wherein the first port, the second port, and the multi-slot aperture are adapted to receive the needle cannula therethrough; a biasing member for biasing the needle cannula within the aperture, the biasing member positionable for restricting movement of the needle cannula in a first direction; and a transverse barrier connected to the binding plate adapted to contact a portion of the needle cannula, and positionable for restricting movement of the needle cannula in a second direction, the second direction being substantially different from the first direction. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)

36. A method of actuating a needle guard, comprising the steps of:
-
providing a needle guard disposed about at least a portion of a needle cannula, the needle guard comprising; a housing, defining an interior, and having a first port and a second port extending therethrough and aligned along an axis of the housing; and a locking mechanism disposed within the interior of the housing, the locking mechanism comprising; a binding plate defining a multi-slot aperture, at least a portion of the multi-slot aperture aligned with the first port and the second port along the axis of the housing, wherein the first port, the second port, and the multi-slot aperture are adapted to receive the needle cannula therethrough; a biasing member for biasing the needle cannula within the aperture; a sensing arm connected to the binding plate and comprising a contact surface, wherein the transverse barrier is adapted to transition from a restrained position in which the contact surface contacts a portion of the needle cannula, to an activated position in which the sensing arm restricts movement of the needle cannula; and at least one biasing element for biasing the binding plate in a distal to proximal direction; and transitioning the sensing arm from the restrained position to the activated position by interrupting contact between the contact surface and the needle cannula.
