Medical needle guard
First Claim
1. A needle guard comprising:
- a base having a needle well;
a handle attached to the base by a connector; and
a needle holder capable of securing a medical needle having a pointed end, wherein the extent to which the base can be moved away from the handle is limited by the connector, and the walls of the needle well completely surrounds the needle point when the handle is distally extended away from the base, and wherein the connector is structured so that the handle is capable of being pushed towards the base such that the needle is guided beyond the needle well.

Abstract
The present invention provides a needle guard comprising a base having a needle well to guide the point of a needle into the patient and, at the same time, for confining the pointed end of a needle within the walls of the needle well until the needle is inserted into a patient. The base is connected by at least a connector to a handle. The connector is constructed to allow the needle to be pushed beyond the needle well thereby exposing the needle. The connector also limits the extent to which the needle can be retracted. This prevents the needle from being pulled past the needle well as the needle is extracted from the patient. As a consequence of the construction, the point of the needle is substantially maintained within the needle well, except when the needle is inserted into the patient. The present invention also provides a method and an assembly for safely handling a medical needle by keeping the needle point confined within the needle well prior to insertion into a patient, and after retraction from the patient.

20. A method of using a medical needle having a pointed end comprising:
-
providing a needle guard having a base comprising a needle well, a handle attached to the base by a connector, a locking means that, when locked, is capable of keeping the handle and the base at distal ends of the connector, a needle holder securing the needle to the guard, wherein the handle is initially extended away from the base, such that a pointed end of the needle is surrounded by the walls of the needle well;
placing the needle guard substantially against a patient so that the needle well is above an area for the needle to be inserted;
pressing the handle towards the base to insert the needle into the patient;
pulling the handle away from the base to retract the needle from the patient, such that the connectors directs the pointed end back within the needle well; and
locking the locking means.
