Abstract
Abstract A small ball of desired size, to be pressed against the skin of a human patient in an area requiring therapy, is revolubly mounted in an end portion of a carrier which protrudes from a holder, with a portion of the carrier received in the holder for reciprocable sliding travel, therein, and a spring member carried in the holder to urge the carrier in one direction of reciprocable sliding travel, with the holder preferably carried by an elongated handle; the holder, and carrier being electrically conductive, and electrical circuitry carried by the handle and electrically connected to the holder whereby mild electrical current may be employed during therapy.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
155 words
A therapeutic device to apply localized pressure, including, a pressure member, an elongated carrier for said pressure member, a carrier holder elongated on longitudinal axis, a hole formed in said holder elongated on and approximately concentric with said longitudinal axis, said carrier including a piston, said piston being received in said hole to support said carrier for reciprocable sliding travel along said longitudinal axis, said piston having an inner end face, means to resist escape of said piston from said hole, said carrier further including a rod portion slidably protruding through said means to resist escape, said rod portion being a smaller diameter than said piston, said rod portion revolubly and terminally carrying said pressure member exteriorly of said holder for application to the skin of a patient, means carried by said holder effective upon said piston to urge said carrier under variable pressure toward the skin of patient in the use of the device.
Claim 2
Dependent Claim
155 words
A therapeutic device to apply localized pressure, including, a pressure member, an elongated carrier for said pressure member, a carrier holder elongated on longitudinal axis, a hole formed in said holder elongated on and approximately concentric with said longitudinal axis, said carrier including a piston, said piston being received in said hole to support said carrier for reciprocable sliding travel along said longitudinal axis, said piston having an inner end face, means to resist escape of said piston from said hole, said carrier further including a rod portion slidably protruding through said means to resist escape, said rod portion being a smaller diameter than said piston, said rod portion revolubly and terminally carrying said pressure member exteriorly of said holder for application to the skin of a patient, means carried by said holder effective upon said piston to urge said carrier under variable pressure toward the skin of patient in the use of the device.
Claim 3
Dependent Claim
47 words
In a device as set forth in claim 1, said means to urge being a yieldably resistant means housed in said holder to react between said holder and the inner end face of said piston, to afford reciprocable manipulation of the device and variation of said pressure.
Claim 4
Dependent Claim
31 words
In a device as set forth in claim 2, said yieldably resistant means being compression spring reacting between said holder and said piston to urge said carrier outwardly of said holder.
Claim 5
Dependent Claim
30 words
A device as set forth in claim 3, further including a handle, said holder being secured in said handle, whereby the device may be applied by manually gripping said handle.
Claim 6
Dependent Claim
53 words
In a device as set forth in claim 4, said holder having an inner end portion embedded in said handle, and a terminal outer portion, said means to resist escape being said terminal outer portion of said holder, said terminal outer portion being deformed to resist escape of said piston from said holder.
Claim 7
Dependent Claim
82 words
In a device as set forth in claim 5, said handle being of electrically non-conductive material, electrically conductive means carried by said handle for making an electrical connection to a source of current, and electrically communicating with said holder, said holder, said compression spring, said carrier, and said pressure member being of electrically conductive material, and electrically communicating in series, whereby a desired electrical current from a source of said current may be conducted to the skin of a patient receiving therapy.
