The invention relates to a treatment chair (1) comprising a headrest (2), connected to the chair (1) with a headrest arm (4), and a position adjustment member (3) for the headrest (2). The position adjustment member (3) comprises at least one ratchet mechanism (5) to lock the headrest (2) in a wanted position.

A foldable massage chair, including a face pillow assembly for supporting a user's head, a chest pillow assembly for supporting the chest, a handrail assembly for supporting wrists, a front support piece, a seat cushion assembly, a main supporting frame, a kneeboard assembly, and back and a front supporting leg assemblies. When using this chair, it is placed in an expanded or use position, so a user may sit on the seat cushion and lean on the massage chair, completely exposing his back, waist, and hips for a masseur to massage. When the chair needs to be put away, it is possible to fold the chair into a collapsed position by folding the seat cushion assembly, front support piece, chest pillow assembly, and handrail assembly. Also, the front and back supporting leg assemblies are folded underneath and towards the main supporting frame. Consequently, the size of the entire chair decreases.

A cushion member that is secured to a massage table or massage chair and contains a video or virtual reality headset within a substantially central opening or cutout of the cushion member to allow an individual to view video, virtual reality scenes, or other text, graphics or indicia while receiving a massage. A retaining shelf can also be secured to the cushion member to provide support for the video or virtual reality headset. Speakers can also be embedded in the cushion member or a headphone jack or port can be provided with the headset to also allow the individual to listen to any audio associated with the displayed material on the headset.

A medical robotic work station includes a frame and a robotic manipulator mounted on the frame for performing a treatment procedure on a patient seated in a chair adjacent the frame. The patient is in a seating posture and support locations are provided on the frame for resting bony members of the patient. Sensors track movement and position of the body members of the patient during performance of the treatment procedure by the robotic manipulator. The robotic manipulator is adapted to perform at least one of a medical, a dental, an ophthalmic and an orthopedic treatment procedure. A physician sits at a display monitor of a physician's work station for programming, monitoring and verifying a robot program for controlling the robotic manipulator to perform the treatment procedure.

An epidural patient positioning system for providing a mobile support platform which is adjustable for a wide range of patient sizes and configurations of treatment tables. The epidural patient positioning system includes a base assembly having a plurality of casters, a vertical assembly extending upwardly from the base assembly, a pair of adjustable foot supports positioned on either side of the vertical assembly, and pair of adjustable arm supports positioned on either side of the vertical assembly, a torso support member positionable both vertically and laterally rom the vertical assembly, and a motor and control assembly.

A headrest device may include a first plate, a second plate, and a locking mechanism, where the second plate is free to shift in any direction along a surface of the first plate while the locking mechanism is in an unlocked state, and where the second plate is prevented from shifting along the surface of the first plate when the locking mechanism is in a locked state. A method may include forming a first plate, forming a second plate, and attaching a locking mechanism to the second plate, where the second plate is free to shift in any direction along a surface of the first plate while the locking mechanism is in an unlocked state, and where the second plate is prevented from shifting along the surface of the first plate when the locking mechanism is in a locked state.

The present disclosure provides a treatment assistance apparatus, comprising: a base; a first joint of which one side is coupled to the base to relatively move; a first arm of which one end is rotatably coupled to the other side of the first joint; a second joint of which one side is rotatably coupled to the other end of the first arm; an adapter arm of which one end is coupled to a first adapter to relatively move, and the first adapter is rotatably coupled to the other side of the second joint; a first driving part disposed in the first joint and configured to rotate the first arm; a second driving part disposed in the second joint and configured to rotate the adapter arm; a pressure part configured to stop a relative motion of the first adapter; and a controller configured to control the first driving part, the second driving part and the pressure part.

A non-restraining collar can include a unitary pillow having extending from a collar body first and second collar straps that extend opposite one another and terminate in respective distal ends separated by a space having a first distance in a relaxed state. The non-restraining collar can also include an elastically deformable spring member embedded in the unitary pillow, the elastically deformable spring member having portions extending into both of the first and second collar straps. The elastically deformable spring member can be deformed such that the first distance is increased to a second distance.

A jaw support device for supporting a patient's jaw during dental procedures. More specifically, a jaw support device comprising a headrest mount assembly, a split sphere assembly having a first locking mechanism, a ball joint assembly having a second locking mechanism, and a jaw rest assembly. The headrest mount assembly may attach to a dental chair headrest. The split sphere assembly may have a split sphere ball and an arm extension and may attach to the headrest mount assembly. Further, the split sphere assembly's first locking mechanism may lock the arm extension in place. The ball joint assembly may have a ball joint ball and may connect to the arm extension of the split sphere assembly. The jaw rest assembly may attach to the ball joint assembly and may be locked in place when the second locking mechanism is activated.

An electric adjustment device for sofa headrest includes a first fixing member, a second fixing member, and a drive device having an output end that linearly reciprocates. One end of the second fixing member is pivotally connected to the first fixing member, and the drive device is pivotally connected to the first fixing member and arranged flush with the first fixing member. A sliding direction of the output end is perpendicular to a pivotal axis about which the second fixing member is pivotable to the first fixing member. Specifically, the second fixing member is extended downward to form a fixed end for fixing to a backrest support frame. The electric adjustment device is installed in the headrest support frame instead of the backrest support frame, so that other functional parts are installed inside internal space of the backrest support frame which improves the function of the sofa.
