Abstract
A device for safely relieving pain in a human or animal includes a pair of pads for placing against a body at spaced apart locations, e.g. on the front and back of an abdomen for treating back pain. One of the pads has an electrically conductive layer, e.g. aluminum foil for placing against the body where treatment is required, and the other pad includes an electrically conductive core sandwiched between insulating layers. The electrically conductive layer and the core are connected to the electrodes of a dry cell or other source of direct current, whereby a direct current is caused to flow between the body and the electrically conducting layer.
Description
PAIN RELIEF DEVICE
This invention relates to a device for safely relieving pain and speeding recovery, and in particular, to a device safely utilizing direct current electricity for relieving pain and speeding recovery in a human or animal.
A need exists for a safe affective device or apparatus for relieving pain, which also accelerates recovery. There is a need for a safe device for relieving pain and speeding recovery that can be adapted to treat any part of the body There is a need for a safe device for relieving pain and speeding recovery that can be worn on the body allowing full mobility, including walking or sleeping, during use.
The object of the present invention is to meet the above-defined needs by providing a relatively simple device for relieving pain that speeds the recovery process on a human or animal body, which is both safe and effective.
Accordingly, the invention relates a device for relieving pain that speeds healing in a human or animal body comprising:
a first flexible conducting pad including a thin, flexible electrically conductive layer for placing against an area of a body experiencing pain;
a second flexible insulated pad for placing against another area of a body spaced apart from said one area, said second pad including a thin, flexible electrically conductive core sandwiched between flexible insulating layers, whereby the core is completely surrounded by said insulating layers;
a direct current electrical power source having positive (+) and negative (-)electrodes; and electrical conductors connecting said conductive layer of said first pad to the positive (+) electrode and said core to the negative (-) electrode, whereby direct current is caused to flow through the area of a body experiencing pain as a result of the electric field created in the body by the core. In references to positive (+) and negative (-) the convention governing the name on the pole as labeled on conventional A, AA, AAA, batteries is employed.
The invention is described below in greater detail with reference to the accompanying drawings, which illustrate a preferred embodiment of the invention, and wherein:
Figure 1 is an isometric view of a device for relieving pain in accordance with the present invention;
Figure 2 is an isometric view of the device of Fig. I in a partially delaminated condition;
Figure 3 is an isometric view of the device of Fig. 1 showing the location of a core in an insulated pad;
Figure 3A is a cross section taken generally along line 3A-3A of Fig. 3;
Figure 3B is a cross section taken generally along line 3B-3B of Fig. 3;
Figure 4 is a front view of a belt incorporating a device in accordance with the present invention; and Figures 5 to 7 are schematic side, back and front views, respectively of a person wearing the belt of Fig. 4.
With reference to Figs. 1 and 2 of the drawings, the basic elements of a pain relieving device include first conducting pad and a second insulated pad indicated generally at 1 and 2 respectively, and a low voltage DC source of power in the form of a dry cell 3, which provides a constant direct current voltage. Suitable sources of power are provided by batteries, including ordinary A, AA and AAA dry cells. While the device illustrated in the drawings is always "on"
and delivers a constant voltage when in use, the voltage can be varied.
The positive electrode 4 of the dry cell 3 is connected by an insulated wire 5, which is copper or another electically conductive material, to a thin, flexible electrically conductive layer or sheet 7, which is bonded to a flexible backing 8 to form the conducting pad 1. As described hereinafter in greater detail, the conducting pad 1 is adapted to be placed against a part of a human or animal body with the sheet 7 in contact with the body at the site of the injury. The sheet 7 is preferably formed of aluminum foil, which is a good electrical conductor, but it can be a foil or mesh formed of another flexible conductive material, e.g. copper, silver, gold, and platinum, an alloy, or any other substance, which will conduct electricity and conform to a part of a body, e.g. a shoulder or a knee. The backing 8 is intended to provide support for the thin conductive sheet 7, and, for such purpose, is formed of a flexible, non-conductive material such as vinyl. The conducting pad 1 should be constructed to be sufficient in area to cover the entire injury to be treated.
A second insulated wire 9 connects the negative electrode 10 of the dry cell 3 to a second thin, conductive sheet (Fig. 2) defining a core 12 in the insulated pad 2. The core 12, which is also preferably formed of aluminum foil, but can also be formed of a foil or mesh formed of another flexible conductive material, such as but not limited to copper, silver, gold, platinum or any other conductive material or alloy thereof, is part of a laminate, i.e.
the core 12 is sandwiched between thin flexible layers 13 and 14 of insulating material. The layers 13 and 14 can be formed of any suitable flexible non-conductive material such as various plastics, latex, duct tape, fabric, cloth, leather or paper. It is merely necessary that the core 12 is completely electrically insulated. The insulated pad 2 should ideally be at least as large in surface area as the conducting pad 1. When the pads 1 and 2 are placed against a human or animal body at spaced apart locations to treat an area experiencing pain or injury, current will be caused to flow between the body and the sheet 7 of the conducting pad 1 which is placed over the area experiencing pain.
The device allows current to flow exclusively between the body and the conducting pad 1 as the insulated pad 2 is a completely insulated core 12, preventing the flow of current between the body and the pad 2. In this respect, no current flows through the body as would occur if the core 12 of the pad 2 were not insulated. The current flow at the site of the conducting pad 1 in contact with the body is caused as a result of interaction between the positively charged sheet 7 and the negatively charged body when the negatively charged core 12 of the insulated pad 2 is also on the body. Indeed, there will be a similar flow of current between any alternate positively charged electrode and the body when a negatively charged insulated core 12 is also on the body. The current flow will be restricted to the contact points made between the alternate positively charged electrode and the skin.
Referring to Fig. 4 the device of the present invention can be incorporated in belt 15 to be placed around the waist of a person 16 (Figs. 5 to 7) for treatment of lower back pain. The belt 15 includes a first pad 1 with the conductive sheet 7, a second pad 2 containing a conductive core 12 and a DC power source 3, in this case a 3-volt battery pack attached to the belt 15. The battery pack 3 is attached to the pad 1 and 2 in the manner described above.
The belt 15 keeps the pad 1 and 2 firmly in position during treatment, and can be worn for long periods of time even when the person is moving. The pad 1 is large enough to cover an injured area, and the core 12 in the pad 2 should be at least as large as the conductive sheet 7 of the pad 1.
When using the invention shown in Figs. 5 to 7 for back therapy, the pad 1 is held against the back of a person 16 with the conductive sheet 7 in maximum contact with the skin of the person and the insulated pad 2 is held against the person's abdomen. While it is preferred, it is neither necessary that the pads 1 and 2 be the same size nor that they be exactly opposite each other on the person. The 3-volt battery pack 1 is connected to the pads 1 and 2 in the manner described above.
Other embodiments of the invention utilize a conducting pad 1 and an insulated pad 2 of appropriate size, depending on the application, for placing on any area of the body experiencing pain. If tape or some form of harness is used the device can be worn allowing full mobility.
In yet another embodiment of the invention, the insulated pad 2 can be placed on the body as described above and a point electrode be used in place of a conducting pad 1 to relieve pain in a very localized area. This will concentrate the current flow to the location experiencing pain safely.
Another embodiment of this invention can use an insulated pad 2 with an alternate electrode in place of a conducting pad 1.
Another embodiment of the invention utilizes an insulated pad 2 used as above and the appropriate electrode to treat any ailment of the body of humans and animals that can be treated using electrical methods of therapy.
Another embodiment of the invention uses a single insulated pad 2 and several conducting pads 1 or alternate electrodes wired to the same power source in order to treat more than one injury on the body simultaneously.
