  • This invention pertains to the field of medical personal protective equipment called PPE.
  • the coronavirus pandemic called COVID 19 has created a major lifestyle modification which warrants certain permanent safety measures that have to be incorporated into our daily routine. This includes total body covering with appropriate vests and using the personal protective equipment to avoid the virus spreading from person to person. The worldwide struggle has triggered an unprecedented wave of innovations to tackle the coronavirus pandemic. In this effort, we have designed an e visor, which is purposed to repel the virus by the electrical charge provided on the surface of the e visor. This concept is applicable to all the other PPEs that are being used worldwide.
  • the visor and other PPE that are being used to protect a person from the virus are available in the prior art. There are several types of visors and PPE. All these are meant to prevent the user from getting infected from other persons and also to avoid infecting others if they are infected. These visors and PPEs help either ways to protect the user and the people around them. Our invention pertains to providing a new scientific concept by making the visor and other PPE with a surface that is electrically charged, which will repel the coronavirus from attaching with the visors and PPE.
  • the existing PPE are all aimed at providing mechanical barrier to the corona virus except one prior art, which tries to kill the virus after using a graphene trap with in the face mask, which kills the virus by allowing an electrical charge, after several hours of carrying the virus with in the mask surface and in the micro groves and pores with in the material.
  • Our concept is much better by way of repelling or killing the corona virus at the first contact.
  • the negatively charged surface that we tend to provide, can repel the virus before getting attached with the mask or visor.
  • the visors and PPE are the basic need of the hour to prevent the spread of coronavirus. So, we have been working to make the visor and the PPE more effective in providing the protection that the PPE must offer to the user. In this effort, we have done a research to prevent the virus from attaching to the surfaces of different materials. There are several studies which tell about the number of hours the virus survives on different surfaces like metal, plastic, linen, floor, water and in the air. According to the available knowledge on this subject, the virus survives the least amount of time on copper metal, which is a very good conductor of electricity. On all other surfaces, the virus appears to survive for longer periods of time, even up to three days on linen and plastic.
  • Covid 19 pandemic has thrown our lives out of gear. We have to harness the nature of the virus to our advantage in tackling it efficiently. Barrier protection methods like visors and masks have helped in cutting the transmission of the virus. Impregnating the visors and masks with anything that can repel the virus based on its characteristics will really add strength to our fight against the virus.
  • coronavirus is negatively charged.
  • Covid 19 is similar to SARS coronavirus and has stated that the virus is detectable for the shortest period of time on copper (4 hrs) in comparison to other materials like cardboard and plastics.
  • copper is a very good conductor of electrons. Electrons being negatively charged will repel negatively charged coronavirus. Therefore the proposal is to impregnate the face visors with solar cells or rechargeable batteries so that the surface of the visor becomes negatively charged which will, in turn, repel the negatively charged coronavirus coming in contact with the mask thereby effectively cutting the transmission. This will significantly augment the effectiveness of face visors in preventing person to person aerosol transmission.
  • any micro organism be it bacteria, virus, fungus , parasites, protozoa, or any electrically charged dust particle, could be repelled by way of providing the same electrical charge on any surface on which we do not want the micro organisms and dust.
  • SARS Severe Acute Respiratory Syndrome
  • the amino acid sequence and domains of the SARS - CoV protein show the clearly charged domains at both the N terminal & C terminal (Schoeman& Fielding, 2019 ).
  • the (National Institute for Health) NIH News Release published on March 17, 2020, on” New Coronavirus Stable for hours on surfaces”, proves that the SARS-CoV is very much similar to the coronavirus family members known earlier in terms of its stability.
  • both the SARS CoV 1 and SARS CoV 2 are similar in the stability study, the scientists are unable to explain why the SARS CoV -2 has become a pandemic.
  • Fig 1 depicts the e VISOR.
  • the Velcro part 1 is like any other headgear to be fixed to the forehead with the help of the threads 9.
  • This hosts a transparent conducting curved glass 2, which is seen on the front aspect. It is meant to provide protection to the entire face from dust, insects, air and any other foreign material affecting the face area.
  • the solar panel 3 which is positioned beneath the transparent conducting curved glass 2, below the level of the eyes 5.
  • the solar panel 3 is optional. This could be a single solar cell or a panel. It need not be present in all the models of the e visor.
  • the transparent conducting curved glass 2 is not provided with the solar panel 3 at the level of the eyes 4 so that it does not block the vision.
  • the wires from the solar panel 7, carry the power generated by the solar panel 3 and stores it in the battery 6.
  • This battery 6 is a rechargeable battery.
  • These wires from the solar panel 7 are connected to the solar panel in the conventional way, which is not shown in the picture, as it could be understood by any common person in this field, which is not the scope of this invention.
  • the battery 6 being a rechargeable one, could retain the power for a longer period depending on its capacity.
  • the entry negative wire 10 carrying the negative charge from the battery 6 is penetrated within the substance of the transparent conducting curved glass 2, and the buried wire is shown as 11.
  • the exit negative wire 12 that exits the transparent conducting curved glass 2 is connected to the LED 14.
  • the exit positive wire 13 runs beneath the top portion of the Velcro 1 and is connected to the LED 14.
  • This LED 14 is used as an indicator and there is no other purpose for this.
  • This indicator is purposed to prove that the electricity passes through the transparent conducting curved glass.
  • the solar panel 3 is exposed through the cut section 8 of transparent conducting curved glass 2 is shown in fig 1 , to make it clear that the solar panel 3 is positioned in such a way that it is covered totally by the transparent conducting curved glass 2. It is also important to note that the solar panel is present only below the eye level 5. The portion of the transparent conducting material at the level of the eye 4, is left undisturbed to provide an undisturbed vision to the user. While the user wears this e visor, the energy produced by the solar panel 3 gets stored in the battery 6 and discharged to the LED 14.
  • the whole transparent conducting curved glass 2 is negatively charged.
  • the wire 11 is void of its plastic non conducting cover. This negative charge is expected to repel the coronavirus, during use, because the coronavirus also contains a negative charge based on the study reports available so far. This concept prevents the spread of the coronavirus from person to person through human contact.
  • the solar panel 3 could be absent entirely, in which case, the power will be discharged from the rechargeable battery 6, which in turn could be charged with the help of any power source.
  • this e visor The ultimate purpose of this e visor is to provide a negatively charged surface on the visor, which will repel the coronavirus. This concept provides safety to the user and to the people around the user. As there is no virus attached to the surface of the e visor, it could be handled safely even while discarding it.
  • the principle could be utilized to charge the linen, furniture, walls and other medical equipment with a negatively charged surface to prevent the coronavirus from attaching itself to these articles. So, the entire ICU or an exclusive medical ward for the coronavirus patients could be kept free of the coronavirus. Thus, person to person cross infections through the PPE and other objects in the hospital could be totally stopped thereby reducing the burden of the coronavirus pandemic.
  • transparent conductive films could be used to be coated over the conventional visors with various transparent plastic materials.
  • the electrical wires will have to pass through this coating in that case.
  • transparent conducting films like indium tin oxide, which is the best conductive film available.
  • polymers, nanotubes and nanowires There are other options like polymers, nanotubes and nanowires.
  • the other possible coatings could be done with doped zinc oxide and fluorine-doped tin oxide. Any transparent conductive material could be the choice to make the transparent conducting curved glass 2.
  • any particular material to pass electricity that is not mentioned in this filing also could be the choice of making the transparent conducting curved glass 2.

Abstract

La présente invention concerne une visière électronique, un EPI, ayant une surface chargée négativement, qui devrait repousser le coronavirus parce que le coronavirus a également une surface chargée négativement. La charge électrique de tout micro-organisme, positif ou négatif, peut être repoussée en lui appliquant la même charge électrique, et le tuer en coagulant la protéine qu'il contient en modifiant la tension et d'autres paramètres électriques. La visière électronique, lorsqu'elle est utilisée, fait appel à la puissance solaire et/ou à une batterie rechargeable pour appliquer cette charge négative sur la surface de la visière. La surface chargée négativement d'une visière, de tout EPI ou de tout autre matériel, instrument et paroi des surfaces qui est exposée au patient infecté par le coronavirus, est exposée au coronavirus. La visière peut également être constituée de matériaux transparents conventionnels et utiliser les pellicules et revêtements conducteurs transparents pour laisser passer l'électricité, pour repousser et tuer le coronavirus.
