Abstract: A needle protector device includes a mount, to which a needle subassembly is fixed, and a protective cover for the needle telescopically coupled to the mount against the biassing of a compression spring. The protective cover is coupled to the mount by a pair of protruding lugs which engage a pair of channels in the mount. The channels each include an entrance portion adjacent the lower end of the mount and an elongated portion extending at an angle toward the upper end of the mount. When the lug is in the entrance portion, the cover is in a locked needle protection position in which the needle tip is covered. To operate the device, the device is placed against a needle-receiving surface and the mount is simultaneously pushed toward the surface and rotated with respect to the cover, causing the lug to move out of the entrance portion to unlock the cover and travel along the elongated portion of the channel. Upon removal of the needle, the compression spring biases to move the cover back over the needle.

Abstract: A needle protector device including a mount having a needle subassembly attached to an upper end, an open lower end, and an aperture in the side of the mount. The aperture includes an entrance position adjacent to the lower end of the mount and an armed position radially spaced from the entrance position by an angled portion of the mount. A protective cover is coupled to the mount and has a protruding lug which engages the mount aperture. The cover is adapted for being a needle protection position in which the needle tip is covered and the cover is not retractable, an armed position in which the needle tip is covered and the cover is retractable, and a retracted position in which the needle tip extends through an open lower end of the cover. A spring having a pair of axial extensions is coupled between the mount and the cover. The spring is biased in rotation and compression during assembly of the device, causing the cover to be automatically urged to the needle protection position.
