Abstract: A medical instrument support mechanism, particularly suitable for ophthalmological instruments, including first and second support arms and a suitable base member in which the first arm is vertically pivotal with respect to the base member and the base member is pivotal with respect to another support member, such as a support pole. The second arm is also pivotally connected to the first arm. A locking mechanism is operatively connected to each of the pivot connections to allow an operator to selectively lock and unlock the pivot connections substantially simultaneously by operating a lever movable in a direction extending along the length of the first support arm. This lever is preferably disposed along a lower side of the first support arm and specifically operates screw locking mechanisms and respective clamp members.

Abstract: The present invention provides a uniquely position adjustable ophthalmic instrument support table for use in conjunction with an examining chair and a lighting system which allows the user to program the desired room lighting independently for each of several inputs such as instrument switches, examination lights or other electrical devices used during an ophthalmic examination. The ophthalmic instrument support table includes a base unit and a table top mounted to the base unit by support structure allowing four degrees of freedom to adjust the location of the table top with respect to both the patient seated in the chair and the doctor examining the patient on the opposite side of the table. The lighting control system allows one or two circuits of room lights to be adjusted in intensity and to have this adjustment automatically recalled to set the programmed room lighting condition upon activation of the input.

Abstract: A medical instrument positioner including a lever arm pivotally secured at a first end to a stationary base, which is preferably the base of a patient support such as an examination chair, and including a pole extending upwardly from a second end as well as a lockable caster secured to the second end for providing rolling but selectively lockable support of the positioner with respect to the base. The patient support provides a heavy, stable object for counteracting the moment created by, for example, a microscope and microscope mounting arm attached to the upper end of the vertical pole. The microscope mounting arm preferably takes the form of a linkage assembly secured to the upper end of the pole. The microscope mounting arm receives the microscope for allowing precise adjustment of the microscope orientation with respect to the patient.

Abstract: An adjustable chair including a control system based around a microprocessor and operated by way of switches preferably located on each side of the seat back. The switches are low voltage flat membrane switches by which the operator moves the chair to a desired position. The switches present a low voltage and sterile environment for both the operator and the patient. The switches can also be easily programmed by the operator to act either in a "momentary" fashion to cause movement of the chair only as long as they are depressed or in a "maintaining" fashion whereby a single depression of a switch causes selected movement of the chair until such movement is stopped by, for example, a limit switch. In addition, one of the switches can also easily be programmed by the operator to alternatively act as either a recline switch or an "auto up" switch. The auto up switch causes the chair to assume a raised and reclined position suitable for performing a specific medical procedure.

Abstract: A hydraulically operated piston apparatus including an outer cylinder having an inner telescopically received piston rod. An elongated slot forms a hydraulic fluid outlet through the wall of the cylinder adjacent the closed end of the cylinder. The piston extends from the open end of the cylinder and, in one aspect of the invention, is rigidly secured to an examination chair to provide for vertical adjustment of the chair. One end of the piston is adapted to gradually block the elongated fluid outlet slot to provide for smooth, linear deceleration of the piston to a stop at the end of its stroke.

Abstract: A medical treatment cabinet having a top work surface and a supply stand extending upwardly from the rear of the top surface. The top drawer of the cabinet has a control panel on its from face for operating various electric examination and treatment equipment. The control panel includes connectors and controls for operating fiber optic instruments and the top drawer contains the control box for the fiber optic instruments and the cabinet power box. One or more electric heating units are mounted above a second drawer for warming instruments contained in the drawer. A lower compartment houses a pneumatic pressure pump and a pneumatic vacuum pump for applying positive pressure and vacuum pressure to the patient during treatment. A vacuum collection container is pivotally mounted within the lower compartment such that it may be pivoted out of the compartment to be easily removed and replaced with a sterile container.
