Abstract
The present invention relates to a microorganism
attenuating cover that comprises of an electrically
conductive material (105), an array of spaced apart
electrodes (101, 103) mounted on the electrically
conductive material (105), wherein a voltage is applied
to the electrodes (101, 103) for inducing current flow
through the electrically conductive material (105) that
attenuates microorganism(s) around the electrically
conductive material (105).
Description
[0001] The present invention relates to the field of
antibacterial covers. More particularly, the present
invention is directed towards a cover for attenuating
microorganism(s) to limit the flow of microorganism(s)
through the cover and reduce deposition of
microorganism(s) on surface of the cover thereby
ensuring safety and prevention from harmful micro
organisms.
[0002] In medical terms, microorganisms are defined
as an organism which is microscopic which may exist in
single cell form or a colony of the cell. As it is
known that microorganisms are widely spread in nature,
wherein some micro-organisms are beneficial while
others may cause serious harm to a human or animal.
There are several kinds of microorganisms such as
viruses, algae, fungi, bacteria.
[0003] For protection from microorganism many
apparatuses, devices, systems are developed and widely
available in the market. The most common one is the
face mask or commonly known as medical/surgical masks.
These masks are made up of cloth layers which try to
prevent the transfer of microorganisms from the air
present in the environment to mouth or nose while
breathing process.
[0004] As it is known that microorganisms like
bacteria or viruses can be airborne i.e. can travel through air so if any individual sneezes or coughs then the tiny droplets of mucous or water scatter into the air which contains the viruses or bacteria and if these droplets come in contact with other individual and that individual touches his nose or mouth then the microorganism transfers into the body causing and worsening disease, examples of this kind of scenario are pandemic viruses such as Spanish flue and COVID 19.
[00051 Another example of such scenario is
tuberculosis which is considered as one of the diseases
induced by Mycobacterium Tuberculosis that is
responsible for infecting any organs in the human body,
but most prominently in the lungs, from inhalation of
small phlegm particles with bacteria floating in the
air into the lungs.
[00061 The mask generally includes an air-permeable
body having an inner surface, wherein the body is sized
to cover the nose and mouth of a subject when worn by
the subject, an inner seal connected to the inner
surface of the body, wherein the inner seal is sized to
form a perimeter around a wearer's nostrils and mouth,
at least one strap connected to the body for securing
the face mask to the subject's face, and a deflector
layer connected to the inner surface of the body,
wherein the deflector redirects at least a portion of
the exhaled air down into the lower regions of the air
permeable body.
[0007] This exhaled breath can irritate the wearer's
eyes, and if the wearer is also wearing glasses,
significant fogging can occur. While anti-fogging strips are available for placement onto typical surgical masks, they, unfortunately, reduce the surface area for air to exit the mask, driving even more exhaled air out towards the eyes.
[00081 Also, modifications to the masks are been
done such as the addition of a lower portion of sheet
material which conforms to the facial characteristics
of a wearer to cover the mouth and nose and includes an
opening in the region of the eyes having an
anatomically contoured covering made of a transparent
optical grade plastic material and forms a seal along
its periphery to protect the openings of the eye from
the invasive entry of viral infectious fluids and the
like while permitting the wearer to wear spectacles in
the normal manner.
[00091 Another modification is a medical face mask
coated with mangosteen shell extracts with a special
and distinguishable feature in that, a part of its
capacity to filter out dust particles, the middle layer
which is coated with mangosteen shell extracts can
protect against tuberculosis and other germs affecting
the respiratory system.
[0010] The advanced level of masks was not disposal
in nature, so a disposal mask was also invented that
included a mask body covering substantially a nose,
mouth, and chin of a wearer, and an extension provided
with the mask body. The extension is configured to
encircle a back of a wearer's head and to substantially
cover a wearer's cheeks, jaw, and ears. A substantial
portion of the extension is formed from a resilient material treated with a repellent agent to prevent contaminants from entering or exiting such a treated portion of the extension.
[0011] In surveys, it has been observed that the
masks are porous due to which it does not completely
limit the transfer of microorganisms, as the layers are
made of cloth-like material which is generally porous.
Additionally, there is no way to reduce the deposition
of microorganisms on the surface of the cover for
ensuring safety. Due to this limitation respirators
were developed which are an advanced version of
surgical masks.
[0012] The most dangerous particles in the air can
be gradually damage the respiratory system over
decades, ultimately resulting in serious illness in the
long term. The respirators protect against aqueous and
oily aerosols, smoke and fine dust in the workplace.
[0013] The respirators generally comprise of that
comprises a mask body, harness along with a filtering
structure, a plastic support structure, and a nose clip
that is secured to the plastic support structure by
being moulded therein. The inventive filtering face
piece respirator is beneficial in that it eliminates
the need for an adhesive or welding step to secure the
nose clip to the mask body.
[0014] The users of this kind of repertory face a
major drawback such as a comfortable fit is not
provided over a wide range of face sizes. Additionally,
there is no way to reduce the deposition of microorganisms on surface of the cover for ensuring safety.
[0015] To eliminate the aforementioned drawback
respirator mask having a soft, compliant facepiece that
has several stiffening elements integrated therein. The
respirator mask preferably includes an exhalation valve
and a pair of filter cartridges. It also has a yolk
which complements the facepiece and provides for
attachment of a harness to secure the respirator mask
to the user's face.
[0016] The respirator mask is lightweight and
extremely comfortable due to the novel facepiece made
of three stiffening elements which are surrounded by
and bonded to the flexible material. After the
development in the respirators, it was observed that an
individual who wears a respirator mask all the time
tends to feel insecure about their appearance that to
not wear the respirator mask, which may have dire
consequences if the infection spreads to the patient or
general public.
[0017] To solve this issue a decorative cover for a
respirator mask was introduced that included a fabric
panel formed from substantially non-filtering fabric
material. A first fastener is attached to an interior
surface on the fabric panel, and a second fastener is
attached to an exterior surface of the respirator mask.
The first and second fasteners releasably engage with
each other to couple the fabric panel as a result.
Thus, it would be desirable to advance the appearance
of a respirator mask.
[0018] Due to the possibility that masks that use a
rigid insert in conjunction with a soft compliant
component appear to be lighter and more comfortable to
wear, they can still be a little more complicated to
make. Masks that use rigid inserts require several
parts and the additional step of attaching the insert
to the flexible, compliant, face-contacting portion
hermetically. Such additional parts and assembly steps
can be required to add to the manufacturing costs.
[0019] But these respirators have disadvantages like
face irritation, difficulty breathing, moisture build
up and the dreaded foggy glasses. Also, the respirators
did not cost-friendly and required a high level of
maintenance due to which every person could not afford
it. To restrict the transfer of micro-organisms many
other wearables were designed and some are widely
popular and are easily available in the public domain
such as personal protection kit that includes but not
restricted to gloves, eye wears a gown.
[0020] The protective equipment consists of garments
placed to protect the health care workers or any other
persons to get infected. If it is blood or airborne
infections, coverings will include: Face protection and
mask or face shield, gloves, gown or coverall, head
cover, rubber boots.
[0021] CN111359319A disclosed nano metal aerogel
sterilization filter material, a preparation method
thereof and a protective mask, wherein the nano metal

The nano metal aerogel sterilization filter material has the advantages of large specific surface area and strong activity, and a nanowire network in the nano metal aerogel sterilization filter material can directly form a large amount of sterilization metal ions under the action of air and water vapor exhaled by a human body, so that the nano metal aerogel sterilization filter material has excellent sterilization performance; the conductive capability is strong, the power supply can be connected to load a strong electrostatic field or a directional electric field, the adsorption capability and killing effect on micro-nano particles, bacteria and viruses are improved, and the micro-nano particles, bacteria and viruses can be repeatedly utilized; meanwhile, the air purifier has small network gaps and low space density, ensures free circulation of air, slows down blockage of particle pollutants, and prolongs the service life.
[0022] KR20170016728A disclosed mask includes a body
for covering a respirator of a user; a fixing member
coupled to the body and fixing the body to user's body;
and a potential difference forming unit for providing
power to the body to form a potential difference. The
body includes an inner cover in contact with the skin
of the user; an outer cover positioned in front of the
inner cover; a dust collecting member disposed between the inner cover and the outer cover for generating the potential difference by receiving power from the potential difference forming unit and adsorbing suspended matters in the air; and an antibacterial member which is in close contact with the dust collecting member and is antimicrobial-coated to kill bacteria or viruses. The present invention is advantageous in that suspended matters in the air can be easily adsorbed through the dust collecting member having the potential difference and the virus contained in the adsorbed suspended matters can be killed by
Lactobacillus plantarum which is an antibacterial
coating material.
[0023] W02013048343A2 disclosed hand coverings, hand
gear, or handwear configured to enable wearer or user
communication with capacitance-sensitive electronic
devices that provide a user interface capable of
detecting or responding to user touch and/or proximity,
for instance, by way of sensing changes in capacitance
(e.g., capacitive touch screen devices). More
particularly, various embodiments of the present
disclosure are directed to an inner glove that can
reside within an outer mitten. The inner glove carries
electrically conductive material(s) corresponding to
portions of one or more hand digits (e.g., the tips
and/or pads of one or more fingers and/or the thumb);
and the outer mitten includes at least one opening
through which such hand digits can be selectively
exposed to an environment external to the outer mitten.
A wearer can communicate or interact with a touch or
proximity sensitive electronic device (e.g., a capacitance-sensitive electronic device) by way of displacing conductive portions of the inner glove through the outer mitten's opening, and positioning such conductive portions of the inner glove upon or proximate to the device.
[0024] The commonly available personal protective
suit for a wearer included a hood portion located
generally above the wearer's neck and at least
partially enveloping the wearer's nose and mouth, a
body portion located generally below the wearer's neck
and at least partially enveloping the wearer's torso,
an air delivery system that can deliver air to the hood
portion, a vent that can permit gasses to escape from
the body portion, and a partial flow restriction
between the hood portion and body portion of the suit.
[0025] The partial flow restriction permits gasses
to pass from the hood portion to the body portion while
reducing carbon dioxide levels in front of the wearer's
mouth. The suit can be fabricated without requiring a
face piece. Additionally, there is no way to reduce the
deposition of microorganisms on the surface for
ensuring safety.
[0026] The wearer of the suit is therefore not
obliged to wear a mask since it is possible directly to
breathe the air contained in the hood. The airflow rate
is adjusted so that there is sufficient air renewal to
avoid a substantial increase in carbon dioxide within
the hood.
[0027] Also, only one air feed can be used, which
allows simplification of the use of the protective system. In this case, however, should there be pressure be a drop in the air supply network, this will give rise to risks for the wearer being ill-supplied with air. There may a sudden increase in the carbon dioxide level inside the hood volume which, within a few instants, may exceed a critical threshold placing the wearer in danger.
[0028] To resolve this issue another modified
personal protective suit was introduced in the public
domain which included a sealed shell equipped with
connection device intended to be connected to one same
pressurized air source, air distribution device having
an air intake connected to the connection device, and
at least one first and one-second air outlet
respectively intended to supply device for delivering
air to the wearer and device for ventilating the suit,
wherein the air distribution device includes a valve
designed to reduce the airflow rate of the second air
outlet when the air pressure at the air intake is below
a determined value while maintaining the supply of air
to the wearer.
[0029] But also, these are made from porous
materials due to which they are insufficient in
restricting the entrances of microorganism into the
human body. Additionally, the users of this kit also
faced the same issues as face irritation, difficulty
breathing, moisture build-up and the dreaded foggy
glasses.
[0030] Certain personal containment systems are also
present in the public domain that employs a non-powered purifying respirator. Air is drawn into the system through a filter by the user's breathing action. When the user draws a breath, negative pressure is created in the system and the air is drawn in through the filter. When the user expels a breath, spent air leaves the system through a valve. Additionally, there is no way to reduce the deposition of microorganisms on the surface of the cover for ensuring safety.
[0031] Due to aforementioned drawbacks and issue,
there is a need to develop a cover for attenuating
microorganisms that not only aims to prevent various
microorganisms from passing through it but also resolve
the issue of microorganisms being deposited on the
covering, and sometimes passing through the covering.
[0032] The main object of the present invention is
to provide a cover that specially aims for attenuating
microorganism(s).
[0033] Another object of the present invention is to
provide a cover to prevent the passing of various
microorganism(s) through the cover.

that is non-porous.
[0035] Yet another object of the present invention

microorganism(s) being deposited on the covering and
sometimes passing through the covering.
[00361 Yet another object of the present invention
is to provide a cover with electrically conductive
material for attenuating microorganism(s) efficiently.
[0037] Still another object of the present invention
is to provide a cover that has an electrically
conductive coating on all contiguous sides.
[00381 The present invention relates to an
antibacterial cover, more especially to a cover with an
electrically conductive material and an electrically
conductive coating on all contiguous sides for
attenuating microorganism(s) along with this resolve

electrically conductive material, an array of spaced
apart electrodes mounted on the electrically conductive
material, whereby applying a voltage to the electrodes
induces current flow through the electrically
conductive material that is responsible for attenuating

porous material (105) having an array of at least two
or more spaced apart, opposed electrically conductive
electrodes (101, 103). The covering (100) may include
any shape from trapezium to square and rectangular on
the basis of requirement.
[00551 The electrical transport properties of the
conductive porous material (105), typically composed of
a non-conductive solid matrix and conductive brine in
the pore space, have numerous applications in reservoir
engineering and petro physics. The electrically
conductive porous material is generally made from any
one or a combination of, a porous electrically
conductive solid material, a porous electrically
conductive semi-solid material, a porous electrically
conductive woven material, a porous electrically
conductive non-woven material for attenuating
microorganisms.
[00561 Referring to Figure 2, a front and rear view
of the covering (100) is illustrated in which the
conductive electrodes (101, 103) on the sides of the
electrically conductive porous material (105)
electrically conductive electrodes (101, 103) being
electrically isolated from each other, and/or extending
over, and/or through a portion of the material, whereby
applying different polarity voltage electrical
potentials to the electrically conductive electrode
segments that induce current flow through the material
will attenuate microorganisms in contact with the
material and/ or flowing through the material, by an
action of the electrical current flow there through to
thereby rendering the microorganisms ineffective and
result in sterilization on, and/ or around the
electrically conductive porous material (105).
[0057] The electrode is an electrical conductor used
to make contact with a non-metallic part of a circuit
furthermore the electrode may be substance that is a
good conductor of electricity and these substances
usually connect non-metallic parts of a circuit for
example semiconductors, an electrolyte, plasmas, vacuum
or even air.
[00581 Additionally, an electrically conductive
yarn, a yarn with electrically conductive coating, a
yarn with electrically conductive material (105), a
collection of electrically conductive fibres, a
collection of fibres with electrically conductive
coating, a collection of fibres with electrically
conductive material (105), a porous material with
electrically conductive coating on all contiguous sides is also introduced in the present invention to make more efficient that the conventional solutions.
[00591 The electrically conducting yarn is a yarn
that conducts electricity in the circuit more
particularly to dissipate static electricity
incorporated with metal wires or wire meshes into
fabrics. The present invention may sue staple yarns,
which uses spin short strands of regular yarns with
metal yarns that may be made of a central metal strand
with regular yarn woven around it.
[00601 Referring to Figure 4, a top view and bottom
view of the covering (100) is illustrated in which only
the conductive electrodes (101, 103) on the sides of
the electrically conductive porous material (105) is
visible. The electrodes (101, 103) are responsible for
simply provide a conduit for positive and negative
electrons to travel through, from one site to another
in the circuit created in the covering (100). The

on the sides of the electrically conductive porous
material (105) is vertically visible.
[00621 As an alternative embodiment of the present
invention, multi layered fabric electrodes (101, 103)
may be used in the covering (100). Moreover, carbon
coated conductive fabric of 100 pm thick may be used for the material of sensing electrode, driven shield, ground (GND) electrode and GND layer in all configurations. Polyester woven fabric of 80 pm thick may be used for insulators.
[00631 As an alternative embodiment of the present
invention the shape of the electrode in the surface may
have specification like rectangle of 7200 mm2.
Additionally, the ground layer surrounding the sensing
electrode and the driven shield protects the electrode
from turboelectric interference. The driven shield was
expected to reduce leakage from the sensing electrode
to ground layer and to keep the sensing electrode being
in high impedance.
[0064] As another alternative embodiment of the

increase system errors.Furthermore, the covering (100)
has a switch of activation and deactivation. The switch
is provided at any part of the cover (100) to turn off
on of the power supply in the cover (100).
[00661 As another alternative embodiment of the present invention, to ensure that cover is robust
towards artefacts, the electrodes must be placed on the
opposite side of the covering (100), which do not hold
the conductive paths. The circuit board, even while
being flexible, also must be placed on the side of the
cover that does not contain the electrodes, in order to
make sure that user comfort is acceptable.
[0067] As another alternative embodiment of the
present invention, a base polymer coat (such as
Polyamide 6 or Polyester) with metal like silver may be
done on the yarn, whereas it is only possible with the
latter to coat non-Polyamides as well. Furthermore, it
is possible to coat filament yarns with other metals
than silver.

present invention, electrically conductive yarns may be
produced from carbon nanotubes (CNT). Individual CNT
based fibres are spun (wet spinning) into a fibre
directly from a solution. The solution either contains
pre-made dissolved CNTs or the combination of chemicals
required to synthesis CNTs.

present invention are described and illustrated herein,
it will be appreciated that they are merely
illustrative. It will be understood by those skilled in
the art that various modifications in form and detail
may be made therein without departing from or offending
the scope of the invention as defined by the appended
claims.
