Abstract: A chiropractic adjustment tool or tapper comprises a housing, the housing having an open end; a impact assembly disposed within the housing and secured thereto. The impact assembly comprises a reciprocating rod with adjustable travel and impact force. An impelling element such as a solenoid is provided to accelerate the reciprocating rod. Disposed on one end of the reciprocating rod is a coupler to permit multiple impact heads to be attached to the tool. The tool is further improved with the addition of a fan unit on a port in the housing and an exit port located on a distal end of the housing, preferably at a location such that air flow is across the impelling element, and any switch or circuitry to provide cooling and extend tool life.

Abstract: A massage device for creating a massaging action using at least one oscillating device. The massage device may be formed from a handle and a head pivotably coupled to the handle. The head may include a first chamber for containing the oscillating device and a second chamber for containing an impeller for driving the oscillating device. The oscillating device may be fluid driven. The massaging device may also include one or more controls in the handle for controlling the action of the massage device.

Abstract: A massage device to be used pre-operatively, intra-operatively and post-operatively. The device that includes a housing with a base portion and a handle portion, a drive unit contained in the base portion of the housing; and a massage node operably connected to the drive unit by coupling means such that operation of the drive unit causes the massage node to provide a massage effect.

Abstract: A therapeutic vibrator comprising a motor contained in a housing, a diaphragm mounted on said housing, and a reciprocating arm connecting the motor to the diaphragm. The housing is fitted with at least one one-way air valve, and at least one air hole so that in operation, the changing volume in the housing effects the pumping of air across the motor and any circuitry to provide cooling. To improve efficiency, a divider plate with at least one air hole is disposed proximate the reciprocating to limit the volume of the pumping chamber.

Abstract: A chiropractic percussor apparatus includes a main housing adapted to be held by a user, an electric motor mounted in the main housing and having a rotary output shaft extending therefrom, an extension housing attached to an end of the main housing and extending outwardly therefrom and having an outer end defining an opening, an elongated push rod eccentrically mounted at an inner end on the rotary output shaft of the electric motor and extending through the extension housing to an outer end of the push rod having a central hole, a flexible coupler assembly supported by the outer end of the extension housing and coupled to the outer end of the push rod so as to permit the outer end of the push rod to undergo reciprocal lengthwise movement and wobbling side-to-side movement relative to the outer end of the extension housing, and a percussion-applying head assembly only centrally attached to the outer end of the push rod at the central hole therein.

Abstract: A percussive massager is provided having a housing supporting a motor having an output shaft rotatably driven thereby. At least one positioning member is movably connected to a percussion arm which is attached to the housing and operably connected to the motor output shaft. At least two massage nodes are operably connected to the percussion arm, one of which being attached to the positioning member, to form a massage surface and move toward and away from the housing to provide a percussive massage effect. A rotary mechanism is rotatable with respect to the percussion arm and drives the positioning member toward and away from a central region of the housing. An ancillary transmission has an output and an input for operably imparting rotation to the rotary mechanism such that the spacing of the massage nodes progressively increases and decreases.

Abstract: A chiropractic adjustor apparatus having an electromagnetic drive mechanism connected to an actuating means which causes a shaft to reciprocate. The reciprocating shaft is used to apply pressure or force directly to the spinal vertebrae of a body. The improvements of this device include a variable-controlled switch to enable the user to change the frequency of the reciprocation; a thermal cut-off switch that automatically turns off the power to the electromagnetic drive mechanism so that the device will stop reciprocating; and a suite of structures that work together to resist rotation when the device is in use.

Abstract: A massaging apparatus (28) which is designed to be located within the space (26) under a bed (20). The massaging apparatus (28) includes a mounting arm (108) which can be moved from the space (26) under the bed (20) and pivoted to an upright position. When in the upright position an elongated arm (32) is connected to the mounting arm (108) and pivotable in a direction toward and away from the bed (20). The elongated arm (32) includes a massaging device (50) mounted on its outer end thereof. The massaging device (50) is to be capable of being separately driven in a reciprocating manner. The elongated arm (32) is to be appropriately counterbalanced (198) so that the massaging device (50) will apply a slight downward pressure onto the human (22) who is being massaged. The mounting arm (108) is to be moved over a preprogrammed path (48) which will also move the massaging device (50) in the same path on the body of the human (22).

Abstract: A body massager including a casing having a slender elongate handle with a massage head extending generally transversely of the handle at one end. The massage handle has an external massage surface contoured symmetrically about a median plane and is mounted for pivotal rocking movement about an axis in that plane. The handle is arranged so that its longitudinal axis also lies in that plane and the massager is balanced about the plane. The massage head is driven by an electric motor which is suspended from an overhead motor mount bracket. Rocking movement of the massage head is controlled by a pair of resiliently compressible sleeves on opposite side of the pivot axis for the head. The massage surface is provided by hemispherical formations which have removable covers so that internal cushion members can be changed for different massage effects.

Abstract: A treatment and stimulation device provided as a compact, portable unit having an applicator capable of horizontal and vertical movements for manipulation of the skin and underlying tissue under electronic circuit control. In a preferred embodiment, the applicator is provided with reversible rotation directed against the skin to provide horizontal movement having uneven angles of deflection, and vertical up/down movement is supplied by a solenoid. By virtue of the electronic control, these movements are continuously variable, and can be integrated and finely controlled, to produce any desired physical stimulation effect on the skin and tissue, for medical or cosmetic purposes. The different kinds of receptors in the skin and tissue can be selectively activated, since they are frequency dependent and direction-force dependent.
