Abstract: A sensor holder for retaining a dental radiation sensing device includes an elongated support member, at least one pair of retention guides attached to the support member, and at least one bite block attached to the support member. The retention guides are capable of holding an associated dental radiation sensing device. The bite block has a leading edge which is first inserted into a mouth of a patient and a trailing edge. The leading edge defining a recess into which structure within the mouth of the patient can seat. At least one of the retention guides may be moveable relative to the other retention guide.

Abstract: A tube holder secures to the rotating processing chamber of a centrifuge tubing that conveys fluid to or from the chamber. The tube holder is part of a carrier that is connected by a pin to a support on the processing chamber. The support has walls defining an enclosure. The carrier swings about the pin on the support between an opened position free of the enclosure and a closed position captured within the enclosure. In the opened position, the tube holder is exposed for receiving tubing. In the closed position, the tubing is retained within the enclosure in the tube holder. The tube holder allows straightforward attachment and removal of the tubing, always in a prescribed manner and with a single hand. The tube holder securely retains the tubing during use in a closed, protected environment, safeguarding it against inadvertent dislodgement, removal, or damage.
