Abstract: Disclosed is a wheelchair for transporting a patient. The wheelchair comprises a support frame having a front, a rear, and opposing sides with the front and rear facing in respective forward and aft directions and the opposing sides facing in opposing lateral directions. The wheelchair further comprises at least two main wheels mounted on the support frame and a seat base disposed upon the support frame between the main wheels. The seat base is configured for selectively raising and lowering the patient between a first level and a second level with the aid of at least one security beam disposed adjacent one of the main wheels. The security beam may have a substantially vertical orientation and may be configured as a hand hold for steadying the patient when transferring onto and off of the seat base.

Abstract: Disclosed is a wheelchair for a patient comprising a support frame, at least two main wheels mounted on sides of the support frame and a seat base disposed upon the support frame. Alternatively, a stretcher topping may be mounted upon a laterally slidable storage compartment that may be affixed to the support frame. The stretcher topping includes a seat base assembly having a removable seat panel stacked upon a potty panel with an aperture formed therethrough and opening into the storage compartment. The potty panel allows for evacuation of the patient while resting in the wheelchair. The seat base and the stretcher topping are configured for selectively raising and lowering the patient between first and second levels. At least one security beam is disposed on the wheelchair and may be configured as a hand hold for steadying the patient when transferring onto and off of the seat base.

Abstract: A drill motor control for periodically varying the rotational speed of a drill to increase the cutting efficiency of the drill bit is disclosed. The speed of the drill is made to vary according to a predetermined cycle such that the drill bit is permitted to bite into the material being drilled at lower speeds, and then the speed is increased to a point where maximum cutting efficiency is achieved. The drill motor control may either be a stand alone apparatus into which a conventional drill is plugged or alternatively may be incorporated into the drill itself. A closed loop control system which senses drill motor current may be utilized to cause the drill motor to slow down as current to the motor decreases when the drill bit ceases its cutting action such as when glazing occurs or when the drill bit has cut completely through the material being drilled. The drill motor control is also useful when the drill is being used as an electric screwdriver.

Abstract: A linear motor apparatus capable of delivery of single or multiple impacts to the body so as to provide massage or other treatment. Frequency, duration and force of impact are operator controlled variables. Resonances may be set up in body tissue material so as to result in standing waves in said body material.

Abstract: An electroacupuncture method in which positive and negative voltages are alternately applied to a selected spot on the skin of the patient, each application of negative voltage serving to condition the skin so that it is more responsive to the subsequently applied positive voltage.

Abstract: An electroacupuncture instrument is powered by self-contained batteries and is of sufficiently small size to be held in the hand of a user. A probe terminating in a moist wad of cotton is the active electrode which applies an electrical pulse to a selected portion of the skin. The instrument case is the other electrode towards which current flows in a return path through the hand that is holding the instrument.
