Abstract: A case and tray for holding at least one high recording density disc. The case comprises a base (14), a cover (11) and a tray (12) for carrying at least one disc is disposed within the case. The tray (12) has a generally rectangular shape and is adapted to fit in the base (10). A cylindrical hub (50, 60) having a locking side and a spring side is unitarily formed and centrally located on the tray. Lips (51, 61) extend from the locking side of the hub (50, 60) and the underside of the lips (57, 67) are spaced from the tray (12) at a distance not less than the thickness of the disc. The portion of hub between the tray (12) and the lips (57, 67) is rigid. Springs (53, 63) are disposed on the spring sides of the hub (50, 60). The springs (53, 63) are adapted to move inwardly when engaged by the center hole of the disc as it is forced over the lips (57, 67) and onto the hub (50, 60) to hold the disc on the hub between the lip (57, 67) and the tray (12).

Abstract: A method of destroying and storing a cannula adapted to contact bodily fluids. According to the method, a cannula having at least one sharp point is disposed in an operative relationship with a reel which is fitted in a housing, A portion of the cannula extends exteriorly of the housing and is slidably disposed within an aperture in the housing. A portion of the cannula that is disposed within the housing engages the reel when it is turned and bends the cannula to destroy it and simultaneously commences drawing the cannula into the housing through the aperture to store it. The turning is continued until the point is fully withdrawn into the housing. When fully withdrawn, the point(s) of the cannula snap against the inside of the housing and provide a sensory indication that they are fully withdrawn.

Abstract: A disposable device for the use, destruction and storage of a cannula useful for placement in blood vessels. The device includes a housing for the cannula with apertures through which the cannula extends and is slidably disposed. The cannula is fixedly disposed through a reel that is fitted in a cavity in the housing. The reel has an axis of rotation at right angles to the cannula and turning the reel wraps the cannula around the reel to deform, destroy and store it. The points of the cannula will be withdrawn into the housing through the apertures. When the points are fully withdrawn they will snap against the inside of the housing to provide sensory indications that the device can be handled safely.

Abstract: A hypodermic syringe having a cannula with a point that can be safely destroyed and stored. A portion of the cannula is disposed within a hollow housing that has a reel fitted therein and a portion extends externally therefrom through an aperture in which it is slidably received. A portion of the cannula is disposed in the reel whereby to enable a user to turn the reel, wrap the cannula around the reel to destroy and store it. When the point is fully retracted into the housing, the point can snap against the inside of the housing and provides sensory indications that it is fully withdrawn. The axis of rotation of the reel is at right angles to the cannula.
