The present invention related to a joint positioning device for positioning a joint and methods for using such devices. The joint positioning device may comprise a patient support comprising a substantially flat surface, the patient support configured to be positioned proximate to a chair; a shoulder pole mounted to the patient support, the shoulder pole oriented substantially perpendicular to a substantially flat surface of the patient support; and a cylindrical shoulder pad mounted to the shoulder pole, the shoulder pad oriented substantially perpendicular to the shoulder pole. The joint positioning device may further comprise a vertical pillar, the vertical pillar oriented substantially perpendicular to the substantially flat surface of the patient support.

A birthing chair for facilitating labor and delivery of an infant. The birthing chair comprises a seat having a seat base and a detachable seat cushion. The seat base forms an aperture for delivery of an infant therethrough. Leg extensions may be attachable to the seat base for supporting the legs of the mother. The seat base may comprise a joint that opens and moves the seat base and leg extensions laterally and expands the size of the aperture in the seat base. The birthing chair may further comprise a suspension system that enables the mother to operate the chair to adjust her position and height at will. The suspension system allows the mother to move in any direction while seated in the birthing chair and still remain supported in the birthing chair. The suspension system may be adjustable. The birthing chair may further comprise a back, headrest, stirrups and handles.

An aerosol containment device is designed for use in containing aerosols discharged during a dental procedure. In some embodiments, the aerosol containment device includes a vacuum source, a vacuum hose connected to the vacuum source, a manifold connected to the vacuum hose, and a clear plastic shield connected to the manifold. The manifold includes a front inlet, a rear discharge connected to the vacuum hose, and a plenum extending between the front inlet and the rear discharge.

A furniture electrical system includes an electrical power unit including a housing that is mountable to a furniture article and that defines an interior cavity, with a low voltage DC electrical outlet positioned in the interior cavity. An electrical power cord is in electrical communication with the electrical outlet and exits the housing, the power cord extending to a higher voltage DC power supply associated with an electric motor for raising and lowering a furniture article. An electrical power converter in the housing reduces the voltage from the higher voltage DC power supply to the low voltage DC electrical outlet. Optionally, an indicia lamp associated with each outlet illuminates at a first luminous intensity when the outlet is energized, and illuminates at a different second luminous intensity when the outlet is energized and supplying power to an electrical power consumer.
