DETAILED DESCRIPTION OF THE INVENTION A portable handheld static-electricity generator for alleviating pain in at least one body portion of a patient is hereby presented in a non-limiting manner. This electro-static field generating medical device is characterized by a movable brush , a polymer assembly which comprising a rubbing-surface portion upon which the brush rubs such that static electricity is generated . The polymer sheet assembly further comprising a discharge portion which is in contact with at least one portion of patient's body

The term "polymer sheet assembly broadly refers hereinafter, in a non-limiting manner to any material which is with a negative charge or positive thereby, is with stronger affinity for negative charge such as silicone rubber, silicon, Teflon, PVC, polyethylene and rubber. Furthermore the term polymer refers to a sheet, beads or pieces of rubber, plastic, glass, pith, and polymer in any form which is made from inert, non-reactive material, for example polydimethylsiloxane or related polysiloxane materials (represented generally by the structure R ₂ -Si-0, where R is a monovalent organic radical, including for example a methyl, ethyl, propyl or phenol group, among others and which may be several thousands of S-O units or more in length and that can build up static electricity on it.

In another embodiment of the present invention the polymer sheet assembly may be a semi conductive material such silicon.

The term "brush assembly" roa.0\y refers hereinafter, in a non-limiting manner to any material which is with a positive charge thereby, is with stronger affinity for positive charge. The brush is composed of a material selected from the group consisting of Polyurethane foam, hair, nylon, Nylatron, glass, paper cotton and any combination thereof.

As used herein the term "aboutX." or "approximately^ refers to a range 25% less than to 25% more than of X (X ± 25%), at times X ± 20%, X ± 15%, X ± 10% and preferably X ± 5%.

According to one embodiment of the invention, the device is characterized by an automatically- operated mechanical unit a brush assembly and a polymer sheet assembly. The polymer sheet assembly comprising a first rubbing-surface portion upon which the static electricity is generated and a second surface portion attached to the patient's body, through which the charge is discharged. The first rubbing-surface portion is the upper surface and the second surface portion is the lowest portion of the assembly, opposite to the first portion. The mechanical unit comprising a DC motor and gear-head thereof, provided in connection with a spur gear by means of a worm gear. The brush assembly comprises a brushing member made of at least one material selected from the group consisting of Polyurethane foam, hair, nylon, Nylatron, glass, paper, cotton, Kevlar, rubber, fabric, leather or any other material having affinity to positive charges. The brush further comprises a brushing material which is in contact with the polymer sheet assembly and a brush body such as a handle or a block which the brushing material is affixed to either parallel- or perpendicular-wise. The brush body is further reversibly or irreversibly attached on the spur gear. The polymer sheet assembly comprises a polymer sheet and base thereof. This sheet is shape in a suitable manner: a planer sheet or 3D designed one (e.g., with a concaved or polygonal structure etc.), smooth or with textured surface etc. This polymer sheet is positioned adjacent to the brushing member, pressed against the polymer sheet inner surface by a spring such that by operating the motor, the spur gear activates or actuates the brush, which is continuously rubbing the polymer sheet for a predefined time period t thereby, generating static electricity upon the sheet, by attaching the electrically-loaded polymer sheet to a patient's body portion, pain is alleviated. The attachment force of the brush to the polymer sheet, which determines the contact surface area and the resultant electrostatic field, can be adjusted by selecting a preferred spring. Furthermore, the effect is greatly enhanced by rubbing the materials, the brush and the polymer sheet assembly together, as they touch and separate many times. For surfaces with differing geometry, rubbing may also lead to heating of protrusions, causing pyroelectric charge separation which may add to the existing contact electrification, or which may oppose the existing polarity. The polarity and strength of the charges produced differ according to the materials, surface roughness, temperature, strain, and other properties.

In another embodiment of the present invention, the static-electricity generator device provides therapeutic treatment of inflammatory and painful disorders and is configured to be held against or supported upon human limbs including fingers, hands, wrists, forearms, elbows, toes, feet or ankles the device is a wearable device having configuration of a belt, a bracelet, a strap, a strip and the like.

In another embodiment of the present invention, the brush may be provided with an Activated Configuration in which moving brush is rubbed against the sheet so as static electricity is generated and a Non-Activated Configuration in which the brush is detached from the sheet and static electricity is not generated and further not discharged due to the detachment. Without wishing to be bound by theory, when two different materials are pressed or rubbed together, the surface of one material will generally 'steal' some electrons from the surface of the other material. The material that steals electrons has the stronger affinity for negative charge of the two materials, and that surface will be negatively charged after the materials are separated. Thereby, when material come into frictive contact, a contact electrification occurs, in which certain materials become electrically charged. The surface of the material is electrically charged, either negatively or positively, any contact with an uncharged conductive object or with an object having substantially different charge may cause an electrical discharge of the built-up static electricity.

The polarity and strength of the charges produced differ according to the materials, surface roughness, temperature, strain, and other properties.

If various insulating materials are pressed or rubbed together and then the amount and polarity of the charge on each surface is separately measured, a very reproducible pattern emerges.

Table 1 below is a Trihoehctricity table which presents materials having positive affinity v.s. negative affinity and how strong the effect will be:

Table 1

The materials mentioned in Table 1 above having negative affinity can be used as a polymer sheet assembly whilst the material having positive affinity may further be used for the brush assembly.

In another embodiment of the present invention, the materials mentioned in Table 1 above having negative affinity can be used as a brush assembly polymer sheet assembly whilst the material having positive affinity may further be used for the polymer sheet assembly.

Reference is now made to Figure 4 which illustrates the polymer sheet assembly 40 comprising a base with a brush lifter unit 41a, a polymer sheet 42 such as silicone, an attachment washer 43 such as Acetal and plurality of stainless steel screws 44.

The brush lifter unit is configured to hold the brush such that the brush is detached from the sheet and static electricity is not discharged thereby, providing the brush in a Non-Activated Configuration.

Reference is now made to Figure 10 which illustrates a graph of the electrostatic field generated from the electrostatic generator device of the present invention vs a time period (t). The charging time of the generator is 10 seconds.

Daily operation of the portable handheld static-electricity generator as defined in the aforesaid embodiment in 6 to 10 sessions per day, of about 15 to about 20 minutes each, alleviates joint pain and improves Wong-Backer Face Scale in one unit after one week.

Daily operation of the portable handheld static-electricity generator as defined and described in aforesaid embodiment in 6 to 10 sessions per day, of about 15 to 20 minutes each (each session comprises introduction of a pulsed electrostatic field, n=10), alleviates muscle pain and improves Wong-Backer Face Scale in one unit after one week of treatment:

EXAMPLE 6

Another object of the present invention is to provide means and methods of a non-invasive treatment for chronic pain relief by utilizing a sheet of occlusive polymer of a thickness between about 2 and 4 mm thickness.

Hence according to an embodiment of the invention, an attached mechanism generates in either a continuous or pulse-wise manner a negative static electrical charge of about 2.5 to about 15 Kilo Volts per inch that is applied to the polymer, providing large amount of negative ions that are being used for treatment.

The continuous charge of ions avoids electrical charge decay due to environmental and patient conditions such as humidity, temperature and perspiration. The negative ions on the polymer repel circulating negatively charged components on the painful area of the body surface over which the device is applied and attract positively charged components, as a result of which a beneficial effect on pain will be accrued.

A pain scale measures a patient's pain intensity or other features. Pain scales are based on self-report, observational (behavioral), or physiological data. Self-report is considered primary and should be obtained if possible (since pain is a quale by definition, and therefore assessment based on any set scale of expected outcomes from similar cases can fail to provide useful clinical data). Wong-Baker FACES pain rating scale, for example, shows a series of faces ranging from a happy face at 0, "No hurt" to a crying face at 10 "Hurts worst".

A set of three different devices are useful for pain relief by reducing Wong-Baker FACES pain rating scale in at least one unit (n=23). In a first device, a negative static electrical field strength of 8.5 kilo Volts per inch of 8.5 kilo Volts (KV) per inch may be applied to the polymer sheet adapted as a barrier in a second system, a negative static electrical field strength of 8.5 kilo Volts per inch of 8.5 KV per inch that is gradually released from a polymer sheet to a Human's skin; and in a third system, a static electricity device that generates about from about 2.5 to about 15 kilo Volts per inch according to a predefined protocol (see e.g., Example 5).

Reference is now made to Figures 15-17 which illustrate the electrostatic generator of the present invention comprising a motor gear, a sheet assembly and a brush having variety of movements.

Figure 15A-C illustrates a semicircle motion brush 151, brush lifter 153, sheet assembly 152 and motor gear 150 thereby, the brush is swung back and forth in a circular bidirectional motion similar to windscreen wiper movement and rubbing the sheet assembly 152 to generate static electricity.
