Abstract: The presently disclosed subject matter is generally directed to a device that is releasably or permanently mountable on at least one blade of a conventional ceiling fan to reduce the number of particulates in the air. Specifically, the device cooperates with a filter to remove a wide variety of impurities from the air, such as dust, pollen, smoke, pet dander, and the like. The disclosed system comprises a device and a filter. The device includes a support that provides a base for the attachment of the filter. The device further includes an adaptor that cooperates with a series of joints to allow the size and shape of the support to be customized for a particular ceiling fan blade. Advantageously, the device can be coupled to a wide variety of ceiling fan blades to enable an associated filter to clean the air as the fan blades rotate, thereby reducing the number of particulates in the air.

Abstract: A fixation device for fastening a medical implant to a patient'3 s bone is provided which includes a fastener with a head member and a shank and a fixation member. The shank has threads along its whole length, and has an outside diameter greater than the width of the head member. The fixation member includes a bore for receiving the fastener. The bore has a diameter intermediate the width of the head member and the outside diameter of the threads of the shank. The head member of the fastener can thus be inserted into the bore such that the uppermost thread abuts against the underside of the fixation member to prevent the fastener from backing out.
