Therapeutic device
Abstract
A handheld device includes a casing having a cylinder presenting
an opening for placement upon a user's skin. A motor is housed
within the casing. A piston driven by the motor oscillates within
the cylinder toward and away from the skin of a user to cause a
pressure fluctuation thereagainst.

Claims
1. A handheld device, comprising: a casing having a cylinder
presenting an opening for placement upon a user's skin, a motor
housed within the casing, a piston driven by the motor to oscillate
within the cylinder toward and away from the skin of a user.
2. The device of claim 1, further comprising a wheel driven by the
motor, the wheel comprising an eccentric pin, the piston having
extending therefrom a follower against which the pin bears to cause
linear oscillation of the piston.
3. The device of claim 1, further comprising a battery located
within the casing and a switch connected electrically between the
battery and the motor.
Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to a therapeutic device for
application to/through the skin of a user to body fat therebeneath.
More particularly, although not exclusively, the invention relates
to a handheld, battery operated device for applying a physical
pressure oscillation through the skin of a user. Such devices might
be said to provide some slimming effect.
OBJECTS OF THE INVENTION
[0002] It is an object of the present invention to provide an
improved handheld therapeutic device for providing an oscillating
pressure to the skin.
DISCLOSURE OF THE INVENTION
[0003] There is disclosed herein a handheld device, comprising:
[0004] a casing having a cylinder presenting an opening for
placement upon a user's skin,
[0005] a motor housed within the casing,
[0006] a piston driven by the motor to oscillate within the
cylinder toward and away from the skin of a user.
[0007] Preferably, the device further comprises a wheel driven by
the motor, the wheel comprising an eccentric pin, the piston having
extending therefrom a follower against which the pin bears to cause
linear oscillation of the piston.
[0008] Preferably, the device further comprises all a battery
located within the casing and a switch connected electrically
between the battery and the motor.
BRIEF DESCRIPTION OF THE DRAWINGS
[0009] A preferred form of the present invention will now be
described by way of example with reference to the accompanying
drawings, wherein:
[0010] FIG. 1 is a schematic cross-sectional side elevation of a
handheld therapeutic device,
[0011] FIG. 2 is a schematic cross-sectional front elevation of the
device of FIG. 1, and
[0012] FIG. 3 is another schematic cross-sectional front elevation
of the device of FIG. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENT
[0013] In the accompanying drawings there is depicted schematically
a handheld therapeutic device 10. The device 10 includes a casing
11 typically formed as a moulded plastics enclosure of one or more
parts. The casing 11 houses a motor 12 and one or more batteries
13. The motor 12 is connected electrically with the batteries 13
via an externally activated switch 14 presenting at the surface of
the casing.
[0014] Extending from the casing 11 is a cylinder 15. Mounted
within the cylinder to oscillate linearly as indicated by the
straight arrow in FIG. 1 is a piston 16. The piston is sealed
against the internal cylindrical wall of the cylinder 15.
[0015] Coupled directly to the output shaft of the motor 12 is a
wheel 19 having an eccentric pin 18 extending therefrom. The pin 18
is eccentric from the output shaft of the motor 12.
[0016] Attached to or formed integrally with the piston 16 is a pin
follower 17 which comprises a lateral slot into which the pin 18 is
received. Rotation of the pin 18 as indicated by the curved arrow
in FIG. 1 causes oscillation of the piston 16 due to its being
captured within the slot.
[0017] In use, the opening of cylinder 15 is placed in sealing
contact against the user's skin--typically at an area of underlying
fat. Depression of switch 14 activates motor 12 to cause
reciprocation of piston 16 toward and away from the user's skin to
cause a pressure oscillation between the piston 16 and the skin.
This will apply a suction action through the skin to the underlying
fat.
[0018] It should be appreciated that modifications and alterations
obvious to those skilled in the art are not to be considered as
beyond the scope of the present invention. For example, rather than
providing a wheel 19 with an eccentric pin 18, those two components
could be replaced by a cam. A cam follower might present a simple
bearing surface against the cam. In this case a return spring would
be needed for the piston 16. Furthermore, rather than being powered
by internal batteries, power could be provided from an external AC
or DC source.
