First Claim
1. In a needle protection device having an elongated housing pivotal to enclose a needle, the housing including a longitudinal slot for receiving a needle therethrough as the housing is pivoted to enclose the needle, the improvement comprising at least one elongated door member hingedly attached to the housing and extending across the longitudinal slot over substantially the entire length of the longitudinal slot, the door member being biased to close the longitudinal slot after a needle has entered the housing through the longitudinal slot.

Abstract
A needle protection device is disclosed having an elongate housing with a longitudinal needle entrance portion defined between two housing side walls. At least one hinged door member is provided extending across the entrance portion to enclose the needle within the housing. In one embodiment the housing has a trap door attached by a resilient living hinge to one side wall and extending across the entrance portion to engage a door stop on the opposite side wall, so that the door is able to rotate about the hinge toward the first side wall to allow the needle to enter the housing, but is limited by the door stop in the degree of rotation away from the first side wall, thereby preventing a needle within the housing from exiting through the entrance portion. In alternative embodiments the door may extend less than the entire length of the housing and/or a needle engaging member, such as a needle engaging hook, may be provided to engage and retain the needle within the housing.

29. A method of reducing the likelihood of contact with a needle or matter thereon, comprising:
-
providing a needle protection device having an elongated housing pivotal to enclose a needle, the housing including a longitudinal slot to receive the needle therethrough and at least one elongate door member extending over substantially the entire length of the slot hingedly attached to the housing and biased to close the slot; rotating the housing into alignment with the needle so that the needle enters the housing through the longitudinal slot past the door member, the door member resiliently closing the slot to contain the needle within the housing after the needle has passed the door member.
