As individuals age or develop certain medical conditions, incontinence may result. Thus, some individuals may choose to wear an undergarment specifically designed to hold urine or feces when incontinence is an issue. Of course, the smart undergarment may be well designed to prevent any urine or feces from escaping from a chamber within the smart undergarment, however, the urine or feces will remain in contact with the skin of the wearer until the undergarment can be changed. In some situations this may be a matter of hours or even up to a day. Thus, the skin of the wearer may develop maladies, such as rash or sores or others as a result of the urine of feces remaining in contact with the skin for greater lengths of time.
Urine and feces often contain bacterium or viruses that can interact and multiply when in contact with the skin. Further, sub-layers of skin may also become infected with these bacterium or viruses and when interacting with additional substances, such as air and moisture, multiplication leads to stronger odor, more skin irritation, rashes, and sores. Stopping, preventing, or otherwise killing these bacterium and viruses are a goal of any smart undergarment suited for this purpose.
For healthy adults with occasional bladder leaks, or prostate leaks or other medical biological leaks; this novel fail-safe smart undergarment anti-microbial design may be useful to hold or even prevent the outward egression of either urine or other bodily excretion.
In an embodiment, a garment, such as an adult pull-up, includes at least one outer section and a midsection attached to the outer section. The midsection includes a first antimicrobial layer configured to contact a wearer's body, a second antimicrobial layer disposed adjacent to the first antimicrobial layer, and an air gap disposed between the first and second antimicrobial layers. The first and second antimicrobial layers each are formed from respective balanced warp tows and fill tows in a plain-weave pattern, and each layer include copper micro filaments or fibers disposed in a plurality of the tows, each of the copper micro filaments or fibers including at least Cu+ ions. Such a smart pull-up undergarment may be suitable for a healthy adult, or children or an adult who cannot use the toilet, and, therefore, may urinate and defecate himself/herself.
In an embodiment, the unique design of the pull-up wicks away a significant amount of excrement and other excretions (e.g., sweat) from the pull-up wearer's skin while resisting tearing that may otherwise occur in response to the stresses and strain caused by defecation and movement of the wearer, and the antimicrobial properties of the pull-up fight infection, rash, bed sores, and other skin irritations that may otherwise occur in response to any un-wicked excrement contacting the pull-up wearer's skin. The midsection of the pull-up, which is configured for covering the genital and anal areas of the wearer, includes first and second antimicrobial membrane layers with an air gap in between the layers. When the wearer urinates or defecates, at least some of the excrement passes through the first membrane layer closest to the wearer's skin into the gap, which effectively holds the excrement away from the wearer's skin. The first layer includes micro copper strands or filaments with Cu+, Cu++, Cu+++ ions that penetrate the wearer's skin to prevent infection, rash, bed sores, and other maladies that may be caused by excrement contacting the wearer's skin for an extended period of time, e.g., between the bio-under garment changes. The second membrane layer also includes micro copper filaments with Cu+, Cu++, Cu+++ to sterilize the excrement in the air gap. Furthermore, the big tow weave pattern of the midsection provides tensile strength & durability to the smart pull-up design even under the stresses and strains caused by defecation and movement of the wearer.
In yet another embodiment, the pull-up includes one or more embedded multi-functional nano-copper sensors that can sense excrement, can indicate the presence of excrement, and can indicate when excrement has been present for more than a threshold period of time. For example, the sensor can indicate the presence of excrement by changing color, and can indicate when excrement has been present for more than a threshold period of time by changing to another color.
The use of transitional metals, such as copper (Cu) and its alloys, as antimicrobial (e.g., antibacterial, antifungal, and antiviral) agents is known, and the literature describes such metals as being used in clothing to prevent odor (by killing odor-causing bacteria), to prevent rashes (e.g., in a garment), etc. For example, U.S. Pat. No. 6,124,221, and U.S. Patent Publication 2004/0167483, both to Gabbay, disclose garments that have Cu++ copper (copper with Cu++ ions) plated onto the garment material. But Gabbay's garment has significant problems. For example, it is theorized that Cu++ ions are more toxic in plated form than other Cu ions such as Cu+ and Cu++, and Cu+++ combined at either the atomic or ionic state.
Furthermore, substances, other than Cu++, (e.g., palladium, zinc) generated during Gabbay's plating process may remain on Gabbay's heavy garment material after the plating process is completed, and may constitute 3%-10% of the combined weight of the plated substances. Unfortunately, these other substances may be toxic, even carcinogenic, to humans. For example, such other substances may cause tissue damage to the skin, and neural degradation of nerves in or near the skin. Moreover, these other substances may diminish the efficacy of Gabbay's Cu++ ions in killing bacteria, viruses, and other microbes and microorganisms.
In addition, Gabbay's garment cannot indicate the presence of excrement so that a caregiver can more easily determine when it is time to remove the soiled garment, clean the garment wearer, and replace the soiled garment with a clean garment. Therefore, a wearer of Gabbay's garment may be in a soiled garment for a relatively long period of time, particularly when the caregiver is busy with other patients and does not have time to physically check the wearer's garment for signs of soiling. Described below are embodiments of an adult or child pull-up that does not suffer from one or more of these problems, and that may have additional advantages, with novel design.
In an embodiment, an adult pull-up includes micro copper filaments with Cu+, Cu++, Cu+++ ions. The use of filaments instead of plating eliminates, from the pull-up, other substances that are possibly toxic and that may reduce the antimicrobial efficacy of the Cu+ ions. And it is theorized that combined Cu+, Cu++, Cu+++ ions are more effective, adaptive, and less toxic than Cu++ ions alone in killing and preventing microbes in and on human skin. More specifically, it is theorized that Cu+, Cu++, Cu+++ ions enter the cell membrane DNA of a bacterium/virus, and change the electrical potential of the cell membrane by binding with an enzyme in the bacterium/virus membrane. This local bio-chemical hyper polarized network results in creating an inhibitory protein molecular structure that damages or degrades the microbe's cell membrane anatomy—and reduces the biological energy-producing ability of the microbe cell, thus “suffocating” the cell so that cell cannot multiply in or on human skin anatomy. The micro copper filaments may also include Cu+++ ions, which are also theorized to be more effective, adaptive, and less toxic than Cu++ ions in killing (99%), reducing, and preventing microbes in and on human skin. By killing, reducing and preventing microbes in and on human skin, the Cu+ and Cu+++ ions can prevent, and mitigate the intensity of, skin irritations such as skin infections, rashes, sores, and other maladies of the skin, that may lead to more complex medical attention.
In another embodiment, the adult pull-up also includes one or more nano-copper sensors that are configured to sense excrement (e.g., feces, urine) and to generate a notification that excrement is present in the pull-up. For example, such a nano-copper sensor may be configured to sense the stresses and strains (i.e., an abuse load) imparted to the pull-up by solid feces, and to change color in response to sensing this load or strain. Furthermore, such a nano-copper sensor may also be configured to sense a liquid, such as urine or liquid present in loose feces, and to change color in response to sensing the liquid. The color that the sensor changes to in response to sensing a load or strain may be the same, or may be different, than the color that the sensor changes into in response to sensing a liquid. And if the sensor senses both a load and a liquid, it may change into yet a different color than the colors for sensing only load or only a liquid. Moreover, after sensing a load, liquid, or both a load and liquid, for a threshold period of time, the sensor may change into yet another color to indicate that excrement has been present in the pull-up for at least the threshold period of time. Such an indication can inform a caregiver that the wearer urgently needs a pull-up change.
The adult pull-up 10 includes a midsection 12, which is configured to cover the anal and genital regions of a wearer (not shown in
The midsection 12, which is further described below, is configured to cover the anal and genital regions of a wearer's body (not shown in
The outer section 14a, which is further described below, includes adhesive, double-split flaperons 22a-22d, and the outer section 14b includes non-adhesive, double-split flaperons 24a-24d.
The flaperons 22 and 24, which are described in more detail below, allow one to configure the pull-up 10 into a wearable form that comfortably fits around the legs, gluteus, genitals, and lower abdomen of the wearer. That is, the flaperons 22 and 24 allow one to conform the pull-up to the body contours of the wearer, and to adjust, and, if necessary, to readjust, the configuration of the pull-up, for a “custom fit.” In one embodiment, the flaperons may secured to a counterpart flaperon, such as 22a to 24a, 22d to 24d, etc. In other embodiments, the flaperons 22 and 24 adhere to the wearer skin without reaching full around to come into contact with a counterpart flaperon.
Once the flaperons 22 are secured to the respective flaperons 24 to form the bio-engineered antimicrobial smart pull-up, the wearer, or the wearer's caregiver, can take the pull-up off of the wearer, and can put the pull-up back onto the wearer, like a pair of shorts or underwear. The bio-engineered antimicrobial smart pull-up's rugged construction (described further below) allows the pull-up to be taken off and re-worn multiple times, at least as long as the wearer does not excrete excrement or other excretions into the pull-up. The bio-engineered antimicrobial smart pull-up could also be disposed of when configured in a less superior material form (e.g., paper or other materials)
In
The first layer 30, which is further described below, is the layer that is closest to, and contacts, the wearer's skin, and is formed from a biodegradable, anti-allergenic, super-absorbent, fluid semi-permeable material that is rugged enough to enable the pull-up 10 to be worn multiple times, and to resist ripping and tearing upon exposure to the liquids present in urine and feces, and upon bearing a load caused by solid feces.
The first layer 30 also includes micro copper filaments (not shown in
And the first layer 30 may also include one or more nano-copper sensors that are configured to sense the presence of excrement contacting the first layer, and to indicate the presence of excrement by, e.g., changing color. As described below, the nano-copper sensors may actually be embedded in the first layer 30, or may be attached to the first layer. Furthermore, as also described below, the micro copper filaments that provide the antimicrobial copper ions may form part of at least one of the nano-copper sensors.
The air gap 32 acts as a repository, or reservoir, for urine, feces, and other excretions (e.g., sweat) that pass through the first layer 30; that is, the air gap holds excrement away from the wearer's skin to help prevent, or to mitigate the intensity of, infection, rash, bed sores, and other skin irritations. Another way to describe the operation of the first layer 30 and the air gap 32 is to say that the air gap allows the first layer to wick away, from the wearer's skin, urine, liquid from feces, and other liquids (e.g., sweat), and to deposit these liquids into the air gap. Furthermore, copper ions released from the micro copper filaments in the first layer 30 may also migrate into the gap 32, and, therefore, may effectively sterilize the excrement in the gap by killing microbes therein. Moreover, the air gap 32 may also serve as a percolating gap that starves bacteria of the oxygen that the bacteria need to multiply, and this starvation, which is in addition to the antimicrobial action of the copper ions, may aid in preventing odor, and preventing/mitigation infection/irritation of the wearer's skin. In addition, the air gap 32 may include one or more nano-copper sensors configured to sense excrement, to indicate the presence of excrement, and to indicate the persistence of the excrement.

The optional third layer 36 is made from a liquid-impermeable material, such as cotton padding or paper, to prevent liquid excrement from leaking out from the pull-up 10. The third layer 36 may be attached to the second layer 34 according to any suitable technique such as with stitching or with an adhesive. The outer section 14a includes a fourth layer 40, which is formed from a biodegradable, anti-allergenic, super-absorbent, fluid-impermeable material that is rugged enough to enable the pull-up 10 to be worn multiple times or disposed of, and to resist ripping and tearing upon exposure to the liquids present in urine and feces, and upon bearing a load caused by solid feces. Although it is contemplated that the midsection 12 will contain the bulk of the urine and feces excreted by the wearer of the pull-up 10 (
Therefore, the fourth layer 40 may include micro copper filaments (not shown in
The fourth layer 40 extends between the ends of the first and second layers 30 and 34, and is secured to the first and second layers by the seam 18a, which may be formed by any conventional technique such as stitching, gluing, or matting. And the third layer 36 extends from the midsection 12 over the fourth layer 40 to prevent liquid excrement from leaking out from the pull-up 10. The third layer 36 may be attached to the fourth layer 40 in any suitable manner, such as with an adhesive. Furthermore, although the seam 18a is described as going through the third layer 36, the seam 18a may not go through the third layer.
Further, the first layer 30 may include two outer sublayer and a center sublayer. The outer sublayers may be attached to the sublayer in any suitable manner such as by gluing. Alternatively, the two outer sublayers may be formed over the sublayer as a coating. The two outer sublayers are formed from a micro foam, such as a cellulose honeycomb core foam, that is natural, super absorbent, biodegradable, and non-allergenic. This foam absorbs and holds urine, liquid from feces, and other liquids (e.g., sweat). When the foam becomes saturated, the excess liquid passes into the gap 32 as described above. In this way, the two outer sublayer act to wick moisture away from the wearer's skin and into the gap 32. The center sublayer, embodiments of which are described below, includes the copper filaments (not shown in
Alternate embodiments of the pull-up 10 are contemplated. For example, the pull-up 10 may include a single flaperon per side of the outer sections 14a and 14b, or may include more than two flaperons per side or no flaperon but a seam (
The embodiment of
As bacteria and microbes are allowed to remain and grow, the maladies may penetrate through the basal lamina 53 of the epidermis layer and through to the dermis layer 56 such that blood capillaries 57 are affected. In turn, the bacteria may further penetrate to the hypodermis layer 58 such that adipose fat tissue 59 is also affected by the malady. It is theorized that Cu+/Cu+++ ions can penetrate all the way to the adipose fat tissue 59 such that the bio-chemical process and biological process of bacteria growth can be interrupted or deterred. That is, the Cu+/Cu+++ ions may be suited to kill or reduce the bacteria or virus all the way into the skin as deep as 0.004 inches (e.g., at least as far as the adipose fat tissue 59 in the hypodermal layer 58.
Furthermore, the warp tows 62 and fill tows 64 can be made from the same natural fabric or superior material (e.g., paper) and have the same cross-sectional dimensions (e.g., diameter), or they can be made from different materials, and have different cross-sectional dimensions. For example, the fabric from which the warp tows 62 and fill tows 64 are made may be any suitable fabric that is one or more of the following: natural, super-absorbent, non-allergenic, and biodegradable. Moreover, each warp tow 62 and each fill tow 64 may have a diameter in the range of approximately 0.015-0.020 (big tow) or 0.00015 to 0.0020 (thin tow) inches. In addition, the warp tows 62 and fill tows 64 may have cross-sections with shapes other than a round microstructural-tow shape, such as flat cross-sections (see, e.g., http://www.easycomposites.co.uk/products/carbon-fibre-cloth-fabric/carbon-fibre-spread-tow-15mm-large-pattern-22-Twill.aspx, which is incorporated by reference).
The above-described weave structure and configuration of the material 60 provides balanced tension and compression in response to an abuse load to mitigate the stresses and strains caused by such a load or strain. That is, the weave structure and configuration of the material 60 allows the first and second layers 30 and 34 of the midsection 12 to distribute the abuse load or strain relatively uniformly so that the pull-up 10 feels more comfortable to the wearer and is less likely to rip or tear. For example, such an abuse load may be caused by movements of the wearer, or by solid excrement that is lodged between the wearer and the pull-up 10.
Furthermore, the above-described weave structure and configuration of the material 60 allows excrement to pass into and through the first layer 30 of the midsection 12 and into the air gap 32, but impedes excrement from leaking out of the air gap and back through the first layer to the wearer's skin. Each warp tow 62 and fill tow 64 includes at least one micro-copper filament 66, which provides the pull-up 10 (
By including micro-copper filaments 66 instead of, e.g., plated copper, the material 60 provides the antimicrobial properties of copper without residues or other byproducts that may be toxic to the wearer of the pull-up 10. Furthermore, the process used to manufacture the pull-up 10 may be less complex because no copper-adding plating step need be performed.

In another embodiment, the material 60 may also include at least one nano-copper sensor 72 configured to sense excrement and to generate an indication of the sensed excrement. In more detail, the material 60 may have warp tows 62 or fill tows 64 that include filaments 74 of nano-copper sensor material instead of the standalone micro-copper filaments 66, and the combination of the nano-filaments 74 and copper filaments 66 form one or more nano-copper sensors 72. For example, the nanomaterial filaments 74 may be nanofibers. For purposes of example, the material 60 is described with the warp tows 62 including the micro-copper filaments 66 and the fill tows 64 including the nanomaterial fibers 74, it being understood that the description of the material 60 is similar with the warp tows including the nanomaterial fibers and the fill tows including the copper micro filaments. Further for purposes of example, the material 60 is described as including only one nano-copper sensor 72.
The micro-copper filaments 66 and nanomaterial fiber 74 form nodes of the nano-copper sensor 72 where the copper filaments cross over the nanomaterial fibers. It is noted, however, that at a node, the corresponding micro-copper filament is integrated with the corresponding nanomaterial fibers. As described below, the presence of liquid excrement, or the presence of a load caused by solid excrement, causes a reaction at the nodes that cause the nano-copper sensor 72 to change color at the nodes where an electro-chemical reaction oxidation is initiated; because the nodes are relatively close together, this color change spreads into non-nodal portions of the nano-copper sensor and thus resulting in the color difference.
In more detail, there exists an electric potential interaction between a copper ions/atoms 66 and a nano-fiber material filament 74 at a specific node. In the presence of a liquid, such as liquid from urine or loose feces, this electric potential causes, at a node 76 (shown in
Furthermore, the nano-copper sensor 72 can be configured to change color after excrement has been present for at least a threshold period of time. For example, the corresponding nanofilament 74 may include ions that migrate to the copper ions more slowly than other ions. So the first ions to interact with the copper ions produce a first color (e.g., green), and then at some time later, the slower ions interact with copper ions to product another color (e.g., red) to indicate that the excrement has been present, i.e., has persisted, for at least a threshold period of time (e.g., 30 minutes). Or the slower nanomaterial ions may interact with the already interacted faster nanomaterial ions and copper ions to form a second substance that has a different color from the first substance formed by the interaction of the faster nanomaterial ions and copper ions. Alternatively, the substance formed by the interaction of the migrating copper ions and nanomaterial ions may change naturally from a first color (e.g., green) to a second color (e.g., blue or red) over a predictable period of time (e.g., 30 minutes).
As described above, the material 60 may be configured to form multiple nano-copper sensors 72. For example, there may be breaks in either the copper filaments 66 or nanomaterial filaments 74, and these breaks define the boundaries between one nano-copper sensor 72 and another nano-copper sensor. Where the material has multiple nano-copper sensors 72, each nano-copper sensor may be configured to generate the same color(s) as the other nano-copper sensor, or to generate different color(s) relative to the other nano-copper sensors.
The following is a more detailed description of the structure and operation of the one or more nano-copper sensors 72 formed by the material 60, including the antimicrobial action of the copper ions provided by the copper filaments 66.
The one or more nano-copper sensors 72 may be formed from nanostructure/copper material that is formed by, e.g., 3D, 4D or 5D printing, at the various nodes of the fabric 60. In the presence of excrement or other excretions, the nanomaterial interacts with the copper ions to change color, where, as described above, the color may increase or decrease in intensity as time goes on to indicate a length of time that the excretion has been present. The nanomaterial in the filaments 74 can be designed to change from any first color (e.g., white or clear) to any second color (e.g., green, blue). The nanomaterials will change the micro structure of the copper ions to make color sensors. Embedding the copper into a conductive nano-tube takes the conductive electrical property of copper interspersed with conductive nanoparticles to form a very complex bio-inspired color sensor 72, which can indicate the presence of human excrement and other excretions. Moreover, such nano-copper sensors 72 can sense both a load and fluid. The novel integrated hybridized multi-walled conductive nanofiber/complex copper ions sensor (anti-microbial design technology) combines and integrates both the unique piezoelectric potential, ionic chemistry, and physical properties of both elements (nanomaterial and copper atoms). This integrated hybridized new sensor-antimicrobial design system acts both as a special type of autonomous or self-regulating sensor to detect both liquids and excrement-induced strains or load on the human skin, when wearing the smart wearable device pull-up undergarment 10 (

Next, at a step 104, the layers 40 of the outer sections 14a and 14b of the pull-up 10 are cut from a sheet that includes the material 60 of
Next, at a step 108, the cut-out first layer 30 is positioned over the second layer 34. If one or more nano-copper sensors 72 are to be disposed in the gap 32, then these one or more nano-copper sensors are positioned on the second layer 34 before the first layer 30 is positioned over the second layer 34.
Then, at a step 110, the seams 18a and 18b are formed (e.g., by “welding,” by gluing, or by stitching) to secure the outer sections 14a and 14b to the respective ends 16a and 16b of the midsection 12 and to form the air gap 32. Next, if the flaperons 22 and 24 are not integral with the layers 40 of the outer sections 14a and 14b, then at a step 112, the flaperons are attached to the outer sections by, e.g., “welding,” gluing, or stitching or other manufacturing techniques. Then at a step 114, the completed pull-up 10 is pressed flat in its open position (the position shown in
