A moving unit includes a housing, a rotary unit to which a rod part is attached, a spring that generates a torque when the rod part is tilted down or tilted up about a rotation axis on the side on which a base portion of the rod part is located, and a torque adjustment unit that is capable of adjusting a torque by deforming the spring. The torque adjustment unit includes a spring deforming portion that deforms the spring in a direction in which the spring is wound up and a spring fixing portion that keeps a torque constant by coming into contact with the spring deforming portion and fixing the spring deforming portion in place.

A dental chair assembly comprises a base, a support, a first pivot mount and a second pivot mount. The support is configured to support a chair seat defined to extend in a forward direction and a chair back positioned rearward of the chair seat. The support has a forward side, an opposite rearward side and a longitudinal axis extending through the forward and rearward sides. The first pivot mount is positioned along the longitudinal axis forward of the rear side of the support and configured to support at least one movable arm. The first pivot mount defines a first upright pivot axis. The second pivot mount is positioned along the longitudinal axis and spaced forwardly from the first pivot mount. The second pivot mount is configured to support at least one movable arm and defines a second upright pivot axis parallel to the first upright pivot axis.

An instrument hose support device includes a rod that supports an instrument hose at a position higher than an instrument that is held by a holder, a pulley support portion that is supported by a distal end of the rod, a pulley that is supported by the pulley support portion and over which the instrument hose is looped. The distal end has a groove in which a taper is formed. A first member of the pulley support portion has a shaft protrusion, and a gap is formed between the shaft protrusion and the groove. The gap serves as the range of motion of the pulley support portion, and the pulley support portion follows the movement of the instrument hose and, relative to the rod, swings freely toward the front and the back and toward the sides and rotates freely with a movable axis (X) as an axis.

An integrated dental care system is provided. The integrated dental care system comprises a dental recliner chair. The dental recliner chair includes a folding frame. The folding frame includes a U-shaped rear leg frame pivotally coupled to a U-shaped front leg frame. The dental recliner chair also includes two side arms. The dental recliner chair also includes a chair frame. The integrated dental care system also includes a dental treatment unit. The dental treatment unit includes a central body. The dental treatment unit also includes of an integrated compressor and suction unit. The dental treatment unit also includes a plurality of tubes. The dental treatment unit also includes a detachable tool box. The detachable tool box is configured to store a plurality of equipment. The dental treatment unit also includes an adjustable handle and a plurality of wheels. Present disclosure provides a low cost, dependable and portable dental clinic.

A restraint chair includes a supporting frame with a seat and a desk. A wrist capture bar is associated with the desk and is displaceable between a retracted position and an extended position. An ankle capture bar is associated with the desk pedestal and is displaceable between a disengaged position and an engaged position. Control levers positioned behind the seat are coupled with the wrist capture bar and the ankle capture bar via a link assembly. Translation of the control levers effects respective displacement of the wrist capture bar between the retracted position and the extended position and of the ankle capture bar between the disengaged position and the engaged position.

An ultrasound diagnostic apparatus in accordance with one aspect of the disclosure includes: a table configured to mount at least one probe; a first sensor configured to detect a type information of the probe and a mounting state of the probe; a driver configured to generate a driving force for moving the table; a second sensor configured to detect a position of the table; and a controller configured to control the driver based on detection results of the first sensor and the second sensor.

An embodiment of the present disclosure a dental chair a chair assembly configured to support a patient. The dental chair also includes a traverse motion assembly coupled to the chair assembly that move the chair assembly in a forward-backward direction. The dental chair also includes a sensor assembly having a rod rotatably fixed to the traverse motion assembly. The rod defines a first end, a second end opposite the first end, and a rod cross-sectional shape. The dental chair also includes a sensor assembly is configured to obtain data indicative a distance of linear movement of the chair assembly along the forward-backward direction between.
