Description

PROTECTIVE GEAR FOR INDIVIDUALS WITH IMPLANTED ELECTRONIC DEVICES AND OTHERS EXPOSED TO HAZARDOUS ELECTROMAGNETIC
RADIATION
FIELD OF THE INVENTION
The present invention relates to protection of individuals from electromagnetic radiation, and particularly to a shielding garment for protecting individuals with implanted electronic devices and other individuals exposed to potentially hazardous electromagnetic radiation.
BACKGROUND OF THE INVENTION
With the increasing use of electronic devices and higher powered distribution systems used in densely populated areas, individuals are often exposed to environmental electromagnetic radiation or fields. With the increasing environmental electromagnetic radiation or fields and the increasing exposure of individuals, there is a risk of harm. There is some evidence that exposure to high doses of electromagnetic radiation or fields originating from such sources as high voltage lines, cellular phones, electric blankets, kitchen appliances, and other electrical devices is potentially dangerous. Environmental electromagnetic fields are particularly dangerous to those individuals having implanted electronic medical devices, such as cardiac pacemakers and defibrillators ; spinal cord stimulators and epidural pumps, used for chronic pain and spasticity management; vagal nerve stimulators, used for seizure control; deep brain stimulators, used for control of movement disorders; insulin pumps, used for diabetes control; and other implantable electronic medical devices. Many of these implanted medical devices are susceptible to electromagnetic radiation or electromagnetic fields produced by electronic devices such as anti-theft surveillance devices, which are widely used in stores, libraries and other locations. Several studies have reported life threatening conditions in individuals having implanted electronic medical devices, due to exposure of theft deterrent devices generating electromagnetic fields. Additionally, many jobs require individuals to be near and around electrically operated equipment generating large amounts of electromagnetic radiation and fields. These 30b locations generally exceed electromagnetic radiation or field exposure levels indicated as allowable by different organizations.
There have been prior efforts to form an electromagnetic shielding garment. For example, U.S. Patent 5,578,359 entitled "Magnetic Shielding Garment For Electro-Biologic Measurements" issuing to Forbes et al on November 26, 1996. Therein disclosed is an electromagnetic shielding garment comprised of amorphous alloy strips or strands woven together. The garment is used to shield a patient from extraneous electromagnetic radiation to allow sensitive medical measurements to be taken with minimal interference. While this garment is effective for shielding extraneous electromagnetic radiation during sensitive medical measurements, it is not suitable or practical and could not be worn comfortably everyday by an individual as a shield for environmental electromagnetic radiation or fields. Therefore, there is a need for individuals to protect themselves from environmental electromagnetic radiation and electromagnetic radiation fields that may adversely affect their health or that may interfere with the proper operation of an implanted or other electronic device increasingly used in the treatment of medical conditions.
SUMMARY OF THE PRESENT INVENTION
The present invention is a garment for everyday wear made of a material or fabric that provides protection from environmental electromagnetic radiation or fields.

In one embodiment, the electromagnetic radiation shielding material is layered between a top layer and a bottom layer of fabric. In another embodiment, strands of electromagnetic radiation shielding material are covered by a fiber material and weaved into a garment. In another embodiment, electromagnetic field shielding strands are weaved alternately with fiber strands to form a fabric. Yet another embodiment is a strand made of a composite material containing electromagnetic field shielding material which is weaved into a garment.
Accordingly, it is an object of the present invention to provide a garment that can easily be worn every day by an individual, protecting the individual from environmental electromagnetic radiation and environmental electromagnetic fields .
It is a further object of the present invention to protect individuals having implanted electronic devices from environmental electromagnetic radiation or fields. It is an advantage of the present invention that the garment is flexible and light and can be worn for everyday use .
It is a further advantage of the present invention that the material can be made into a variety of garments including shirts, pants, gloves, socks, hats, blankets, bedding, or any other clothing or garment worn or placed over an individual.
It is a feature of the present invention that a high magnetic permeability or ferromagnetic material is used in combination with a fiber material.
It is another feature of the present invention that electromagnetic radiation or field shielding materials are blended with fabric materials .

The shirt 12 and pants 14 are made from a fabric or material providing electromagnetic radiation or field shielding. The garment provides protection to the wearer from environmental electromagnetic fields. The environmental electromagnetic fields may be generated from a variety of sources such as electrical equipment, electronic anti-theft surveillance devices, high voltage lines, cellular phones, electric blankets, kitchen appliances, motors, and generators, among numerous other sources using electrical energy or magnetic devices. Tne electromagnetic field shielding garments of the present invention are particularly applicable to individuals having implanted electronic medιca_ devices, for example a cardiac pacemaker or defibrillator 16 or spinal cord stimulator 18. As the use of implanted electronic devices grows and as the implanted electronic devices use less power and therefore become more sensitive tc currents induced by electromagnetic fields, their shielding becomes particularly important. Even relatively low electromagnetic fields may adversely effect and cause improper operation of many implanted electronic devices. Such malfunctions may be life-threatening for many individuals. Accordingly, electromagnetic field shielding garments, to be effectively utilized, must be flexible, lightweight and easily worn for long periods of time. Various materials having a magnetic permeability may be incorporateα into electromagnetic field shielding garments utilizing the Faraday cage principal. For example, aluminum and stainless steel may be used, as well as other ferromagnetic compounds. Carbon fibers may also be used with other composite type materials such as fiberglass and plastic. Stainless steel containing fabrics are commercially available in different proportions of stainless steel to fabric, with different weaving, knitting or braiding techniques. The present invention, by utilizing a combination of various fabrics traditionally used in the clothing industry with various other high magnetic permeability materials or substances, can be designed and manufactured into normally appearing wearable garments that can be used day to day. The electromagnetic field shielding garments of the present invention can be utilized not only for protecting patients with implanted electronic devices or individuals subject to environmental exposure of electromagnetic fields, but also for protecting patients undergoing chemotherapy, radiation therapy or other immunosuppressive treatments, that might be more prone to the potential hazardous effects of electromagnetic fields. Additionally, the present invention may be used by military, police, and security forces as a defense against potential use of high electromagnetic fields as weapons against human staff and their equipment.
