摘要： Improvements are provided for a dental air abrasive system of the type which utilizes a compressed gas or air which creates a gas stream. Abrasive particles are introduced into the gas stream and expelled out through one end of a nozzle whereupon the abrasive laden gas stream impinges upon the target, i.e. tooth amalgam, composites, stain and/or tooth dental filling materials. The improvements include the use of two or more hoppers each containing different sized abrasive particles, which are selectively fed, either together or independently of each other, into the gas stream. Different sized abrasive particles are provided in each hopper for cutting different types of tooth structures. Other improvements include the use of fluorescent and/or colored abrasive particles to facilitate the aiming process, a laser beam, strobe, white light or other illuminating means for aiming the abrasive stream and/or illuminating the target area as well as a disposable nozzle for hygienic reasons. Other improvements include the use of a vacuum evacuation system to minimize dusting of the abrasive particles, as well as a dam removably positioned within the patient's mouth which reflects the abrasive particles back towards the evacuation system. Still other improvements include the use of a microvalve adjacent the nozzle which, when closed, terminates gas flow through the fluid passageway in order to further minimize dusting of the abrasive particles.

摘要： An apparatus is disclosed for stretching tendons, muscles and associated soft tissues of human joints. The apparatus includes a generality planar frame having two sides, two ends, a lower surface adapted to be supported by a ground support surface and an upper surface. An elongated upright support has a first end which is secured to the frame so that the second end of the upright support extends generally vertically upwardly from the frame. At least one pulley is secured adjacent the upper end of the upright support. Thereafter, an elongated cord has one end adapted to be secured to the limb of a human user and this cord extends through the pulley. The human user, by pulling on the cord, stretches the limb of the human user in the desired fashion. By attaching the cord to different limbs and assuming different positions, the human user can stretch his or her tendons, muscles and associated soft tissues of numerous joints and a numerous stretching positions.

摘要： A combination air abrasive system and laser system are provided for dental applications. The air abrasive system creates an abrasive material laden gas flow and then directs this gas flow towards a target site in the patient's mouth. The air abrasive system also includes a vacuum system which creates an air flow to remove the abrasive material after impingement on the target site. The abrasive material is filtered from the air flow and the resulting clean air is then used to create a positive pressure within the housing for the dental laser system to prevent the entry of debris and other contaminants within the laser system. Additionally, the clean air flow is used to clean the lens system for the laser. Also, the air abrasive system and laser system include a common control system and may also utilize a common aiming and illumination mechanism. Further, the combination unit has a common light source that not only illuminates the target area, but can be used as a curing light for dental materials, which light source may or may not be a laser. Further, the combination unit has a single common footswitch that allows the performance of more than one task.

摘要： A handpiece assembly is disclosed for use with a dental laser assembly of the type having a laser and an elongated optical fiber assembly. The optical fiber assembly has a proximal end which receives radiation from the laser and a distal end which delivers the laser radiation to a target site. The handpiece assembly includes an elongated handpiece which is dimensioned to be held in a human hand. A longitudinal throughbore is formed in the handpiece and is dimensioned to slidably receive the optical fiber assembly so that the distal end of the optical fiber assembly extends outwardly from one end of the handpiece. A locking assembly removably locks the other end of the handpiece against longitudinal movement to the optical fiber assembly. Furthermore, the entire handpiece assembly is discarded after use on a single patient to prevent disease transmission by the handpiece.

摘要： A safe is provided for use with a wall having an air duct and an opening to the wall which connects the air duct with a room. The safe includes a housing having an interior dimensioned to fit within the air duct so that the housing is recessed in the wall and in alignment with the wall opening. A grille dimensioned to cover the wall opening is pivotally mounted to the housing so that the grille is movable between a closed position in which the grille overlies and covers the wall opening and an open position in which the opening interior is accessible from the room. A valuable container is mounted within the housing or, alternatively, on the rear side of the grille. Additionally, air passage holes are formed through the housing for enabling air flow through the housing, grille and air duct. Alternatively, the grille is magnetically attached to the housing.

摘要： The present invention discloses a method for preparing tooth structure, such as dentin and enamel, for bonding with a composite material. The method includes the steps of creating a fluid stream laden with an abrasive material, such as aluminum oxide. The fluid stream is directed towards the tooth structure so that the abrasive material laden fluid stream impinges upon the tooth structure and roughens it for enhanced bonding with composite material.
