<p>A disposable safety protection device consists of a hub and a cover. A conduit for guiding fluid is disposed in the center of the hub, various types of medical needles can be secured to the front of the hub. The walls of the dissociative conduit in the center of the hub are thin and exposed. A future is disposed in the outer surface of the walls of the hub, which engages with the ratatable wheel on the cover and the axis of the wheel. A point projecting inwardly from the inner walls of the handhold can penetrate the walls of the conduit so as to disable the hub and the whole needle, when the cover fastens the hub. The seat cover at the end of the cover extends forwardly to form a needle cover. The projections disposed in the lower edges of both sidewalls of the seat cover can fasten the walls of the hub. A cavity formed by the elastic sheets is disposed in the front cavity of the needle cover so as to protect the needlepoint when the cover fastens the hub.</p> |
