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.
