The present invention relates to an article and dressing for improved healing, and in particular for an article for improved healing creating a virtual scaffold.
Wounds can occur in a multitude of ways, an injury, or through surgery, for example, with damage through layers of connective tissue. One or more of these connective tissues, skin, ligaments, tendons, cartilage or even bone, can be damaged and the body will immediately start to try to heal. Medical treatment will be sought for the injury, and the wound evaluated and cleaned. During this initial stage the person may be in some pain or discomfort due to the injury.
Once the nature of the wound has been established, usually the next step is to stitch the wound, to hold the edges of the wound together during the healing process. Local anaesthetic is often used to numb the area before stitching but the administration of local anaesthetic is painful in itself. Children, already in pain and somewhat upset by their injury, are further traumatised by the use of local anaesthetic and stitching with a metal needle and thread. Therefore, this is a traumatic experience not only for the young patient but for their parents, who are often required to restrain their child during treatment, and for the health practitioner.
The stitches need to remain in place long enough for the layers of the skin to reconnect without the risk of the wound reopening. For most wounds stitches will need to remain in place between 10 to 14 days before being carefully removed by a health professional. During this period the stitches may be knocked or become damaged as 10 to 14 days is a long time to carefully protect the injury. Or during this time the wound may simply open up. In either case the wound should be restitched to close the damaged area and avoid excess scarring. However, often the restitching may not occur and where the edges of the wound are not being held together during the healing period, the wound will still try to heal but the tissues will not be in the desired position, leading to scarring. Such scarring is usually permanent, unless the wound is reopened, the scarring removed and then stitched and allowed to heal over again. In this case some additional scarring is still likely as the new wound will be larger than the original wound.
Scarring is very common, even in well managed stitched wounds. Scarring occurs when the connective tissue within the damaged area aligns differently to the healthy tissues during the healing process. Connective tissue primarily consists of an extracellular matrix formed by the alignment of collagen and proteoglycan molecules, and it is this matrix that gives structure and strength to the connective tissue. In healthy, intact, tissue new collagen and proteoglycan molecules flow into the extracellular matrix and align with the existing molecular structure. Collagen molecules align linearly with one another to form collagen fibrils. The fibrils combine to form fibres, which in turn align linearly to one another. The proteoglycans align perpendicular to the collagen fibres forming the “matrix”. These molecules align in this way due to the magnetic properties of the molecules. Collagen being diamagnetic aligns perpendicular to a magnetic field and proteoglycans align parallel to a magnetic field, perpendicular to the collagen fibres. During healthy regeneration the new collagen and proteoglycan molecules align with the existing matrix due to the magnetic properties of these molecules.
However, when connective tissue is damaged the extracellular matrix is disrupted and the collagen and proteoglycan molecules flowing into the wound are unable to align properly. Some collagen molecules align in one direction while others align in a different direction. Some proteoglycans can attach to these collagen clusters but, in the absence of the extracellular matrix, these clusters will be small and weak relative to heathy tissue. Over time there will be healing but it may take weeks for sufficient tissue to repair to heal the wound. More than 4000 collagen molecules must align properly to span just 1 millimetre of damaged tissue, a factor in why connective tissue injuries are slow to heal and can lead to significant scarring.
The subject invention has developed a surprising, clever new way of using a magnetic field to create a virtual scaffold for wound healing that significantly reduces wound healing time from 10 to 14 days to less than 24 or 48 hours. Through use of the inventive device including a one-sided flux magnet (Halbach array), a virtual molecular scaffold is projected into the wound or area to be healed so that the collagen and proteoglycan molecules flowing into the wound can correctly align within the magnetic field and start to immediately repair the damage. Instead of aligning in clumps and clusters, the created multiple orthogonal magnetic fields mimics the magnetic signature of healthy tissue to promote rapid healing, with minimal scarring. As the collagen and proteoglycans align as they would in healthy tissue, the scarring due to misaligned repair is very little or in some cases may be almost nil. After a wound starts to heal, there is relief for the patient, and the pain will diminish, but unsightly scarring can cause long term distress; minimisation of scarring is an important advantage to the subject invention.
The subject invention is a painless and non-invasive device and method, enabling easy application and use. The device can be used in the field or at remote locations with minimal equipment or training, to align the device and start use immediately the wound is treated. In emergency situations the invention can be readily applied by the patient themselves or anyone else present, if there will be delay before professional health care can be sought. Remote health can easily talk through the use of the invention with advice from a health professional in a city-based hospital or clinic, for example.
Production costs can be kept low to produce a very useful article for treatment of wounds that can be made widely available. It is envisaged that the article will become a staple product in hospitals and medical centres, but also will be available direct to patients so that they can, in an emergency, apply the device to a wound themselves. The great many very useful applications of the invention are too numerous to list. A particularly useful application of the invention is healing surgical incision wounds or healing excision wounds where a potentially cancerous lesion or mole has been removed. A larger excision may be required if the initial excision is found to be cancerous. These large wounds can take a very long time to heal, and can lead to a significant and unsightly scar, which is clearly an undesirable result of necessary surgery. With use of the invention, the healing time will be dramatically reduced, even for large wounds, and the resultant scarring minimised, which will be very pleasing to the patient. It is envisaged that most patients, given a choice, would choose not to be stitched and to use the subject inventive device with minimised chance of scarring over conventional methods, which is a strong support for the high merits of this important invention.
In hospitals or medical centres, use of the invention will enable a rapid application of inventive wound dressings, with minimal discomfort to the patient, so that the patient including children can be attended to quickly and with minimum additional pain or trauma. With the wound rapidly dressed and comfortable, the patient will be able to leave the health centre quickly with the knowledge that the wound is healing properly and rapidly, due to the application of the virtual scaffold.
For those caring for animals, the same difficulties arise when treating wounds, and for animals there is no way to communicate to them about what is happening. For some animals it will be necessary to sedate them to treat the wound, and for older animals this is undesirable as there is increased risk of complications. Use of the subject invention, such as for neutering operations for cats, as an example, will enable a ready application of the wound dressing, and rapid healing, so that the cat can be back to normal activities as quickly as possible. This compares to the need to be stitched, protect the stitches from damage or investigation by the cat themselves, and then 10 to 14 days later returning to the vet to have the stitches removed. The absence of stitches by using the invention removes the need to return to the medical or veterinary centre to the have the stitches removed, a further practical and economic advantage over conventional wound healing.
It is envisaged that the product will be universally adopted, once known about, and is likely to develop several important product lines over the coming years. This important new invention has a plethora of new uses and applications in development and is likely to be found very useful in a very wide range of applications for people and animals alike.
The following describes various non-limiting examples of the invention being used with reference to wound healing of the skin of a person, and in deeper tissues such as in the ligaments of the knee or the bones of the arm, for example. The invention has a great many applications and it is not intended that the wounds treated be limited in any way to the given examples; any suitable wound may be treated through use of the invention. Further, the examples given are of wound treatment of a person but the invention is equally useful for wound healing in animals. It is not intended to limit the wound healing to people, or animals, other than as defined in the claims. Further the invention is useful where there is no wound, but for treatment of skin that would benefit from improved alignment in regeneration through use of the projected virtual molecular scaffold. Therefore, the invention is not intended to be limited to wounds, per se.
The invention for wounds, makes use of layers of items, to close the wound, apply the one-sided flux magnet, and then maintain the magnet in place. Clearly, there are numerous variants to these layers and to the way these are arranged and it is not intended to limit the arrangement to as shown in the examples, other than as defined in the claims.
For clarity, any prior art referred to herein, does not constitute an admission that the prior art forms part of the common general knowledge, in Australia or elsewhere.

It is envisaged that the invention can be used in medical treatment by professionals to treat wounds, or if a person is away from professional medical treatment, they may treat themselves. It is an advantage of the invention that use of the invention is so much easier to apply than stitches, and can be applied by anyone, without the need for professional training. With the increased use of “tele-health”, where a professional can see and advise a person through a video link, straightforward dressings are useful as a person can be talked through the steps to apply. The professional can advise the person at the other end to the proper application of the invention for successful wound dressing, which would be much more difficult, or impossible for stitches. In a remote or emergency situation, a person may become injured and may be many hours or days from medical treatment. In this case a satellite phone may be used to seek help, and advice, and if the person is carryings the inventive dressing and magnetic device with them, they can apply this in an emergency. The invention is very useful for these emergency situations since it can be readily used without the need for professional training, with simple instructions, but leading to a dramatically improved healing outcome, and significantly accelerated healing.
In the given example, wound 10 is a deep accidental cut in arm 1, that has been presented to a doctor for treatment. Wound 10 and surrounding skin 12 has been cleaned of dirt and debris, and is ready to be dressed. The next step after cleaning is the closing of wound 10 with surgical tape 14. There are a number of self-adhesive surgical tapes and paper stitch products available and any suitable means can be used to close the wound. As illustrated, a suitable length of HYPAFIX (Trade Mark) self-adhesive woven surgical tape 14 is cut and applied along one side of wound 10 on cleaned skin 12. The strip of HYPAFIX (Trade Mark) 14 is then pulled over to tightly close wound 10, and adhered in place on the other side of wound 10, on a section of clean skin 12. Lower surface 16 of surgical tape 14, has a self-adhesive suitable for application on skin so that it adheres tightly, while the upper surface 18, is lightly textured. In
Once wound 10 is suitably cleaned and closed with HYPAFIX (Trade Mark) strip 14 or similar, magnetic device 20 is applied as shown in
The cleaned, closed wound 10, with magnetic device 20 applied is then held in place by application of further surgical tape 22, applied by the health professional to secure magnetic device 20 to HYPAFIX (Trade Mark) strip 14 and surrounding skin so that the HYPAFIX (Trade Mark) 14, and magnetic device 20 are fully covered and protected from disturbance while the patient is healing. Surgical tape 22 is shown as being the same as strip 14, but any suitable surgical tape, paper bandage of the like may be used for securing. Depending on the type of wound, and the other injuries of the person, further tape, dressings or bandages may be applied if desired for the comfort of the patient or for further protection of wound 10. In this way the dressing is applied to wound 10 to close the wound, HYPERFIX (Trade Mark) strip 14, and magnetic device 20, to project the magnetic field to create a virtual scaffold for healing as described below, and sealed and secured in place by surgical tape strip 22.
The dressing as described in
With reference to
Layer b) is magnetic device 20, suitable to act on the underlying tissues. As shown a one-sided flux magnet, a Halbach array, in a silicone medium which provides a specific arrangement of magnetic fields. The silicone medium is safe for the patient, and can be readily produced and used. The thickness as shown of 1.0 millimetre is useful for magnetic device 20, including the Halbach array and silicone medium for typical cuts and wounds. Other useful thicknesses include 0.5 millimetres, 2.0 millimetres, and other useful thicknesses as desired by the user. The specific arrangement of magnetic field is useful for creating and projecting a virtual scaffold to enable the healing of the underlying tissues to conform to a desired alignment.

At the core of the invention is the mechanism for alignment of collagen and proteoglycan molecules in healing tissue. Where the molecules align, as in undamaged tissue, healing is rapid and the scarring is minimal. However, where the alignment is different to the usual structure healing is slow and scarring occurs. Although scarring may fade somewhat over time, thick scarring such as keloid scars are usually permanent and extremely unsightly.
To avoid scarring, it is desirable to hold the wound edges closely together for healing, such as with stitches. But this has been found to be insufficient, and often stitched wounds still lead to scarring, and this can be compounded if the stitches come apart during the 10 to 14 days required for healing. In the present invention, the action of magnetic device 20 provides a virtual scaffold to the healing tissues, to dramatically shorten the time required for the molecules to align correctly and rapidly heal wound 10 so that additional closing of the wound in no longer required.
As described elsewhere, connective tissue contains an extracellular matrix made of collagen and proteoglycans (with other molecules), and it is this matrix that gives structure and strength to healthy connective tissue. Equally, as a wound attempts to heal the collagen and proteoglycan molecules attempt to align to give structure and strength to the healing wound. It is the multiple orthogonal magnetic fields created by the device and aligned with the length of the wound that enables improved wound healing. As the collagen and proteoglycan molecules are encouraged to correctly align by the virtual molecular scaffold created, the healing is accelerated, and aligned as the healthy tissue before the damage.

Where the subject invention is used instead, as shown in
A strong advantage of the virtual scaffold created by use of the invention is the precise realignment of the molecules reducing the healing time to a minimum. In standard healing there is a random alignment until the collagen fibres can form in a suitable structure for healing. In use of the subject invention, from the application of magnetic device 20, the virtual scaffold guides the structure of the skin healing, such that the healing occurs as quick as the molecules can align and repair the deficit. No time is wasted forming scar tissue but is instead used to heal the wound. This significant invention therefore can heal a wound in a matter of hours rather than weeks, as only the necessary healing is carried out by the body.
For the patient, a pain free application of the inventive dressing and with layers a), b) and c) is a non-invasive means to treat wound 10. The result is that the wound will very quickly heal, in some examples less than 24 hours rather than 10 to 14 days as the molecules do not waste time in misalignment but are fully aligned within the virtual scaffold from the start. The result is a quicker healing wound, with less scarring and without the trauma of being stitched or the removal of the stitches. This clever invention has a multitude of potential applications and uses.

Magnetic device 120, is a Halbach array which works as described for the first embodiment in a silicone medium, which can be used with or without dressing. Dressing 126 contacts on skin 128 and magnetic device 120 positioned over dressing 126. The arrangement is fixed in place to leg 101, by an outer wound dressing knee support 138, fixed over the other layers for the comfort and support of the knee and to ensure the magnetic device 120 remains in place.
As for the first embodiment magnetic device 120 creates a virtual molecular scaffold to guide the aligned healing of the connective tissues. The invention may be used to heal many kinds of connective tissue damage, which may be the result of an injury or surgery. In either case the virtual scaffold projected by magnetic device 120 facilitates correct alignment of the molecular structure reducing the time needed to heal the injury and reduce scarring. It is highly desirable to reduce deep tissue scarring, as scarring in deep tissues, including ligaments and tendons, can increase the chance of similar damage to the same tissues in the future as the scar tissue is not as strong as healthy, undamaged tissue. Reduced scarring in these deep tissues is therefore of benefit in the short term and in the long term to resist future injury. Again, the application of the subject invention provides a highly beneficial non-invasive treatment, leads to rapid healing with minimal scarring in the skin or deep tissues, a highly desirable result for the patient.

For all the embodiments the invention provides a clever, easy to use, non-invasive treatment, which should be considered a significant advance over the prior art. The product itself is something that can be used by both health professionals and individuals. The shelf life is estimated to be 5 years, but some forms may have a longer shelf life. The product is supplied as a roll to be cut to size suitable for the wound in a cardboard dispenser. It is anticipated that widths of 20 or 50 millimetres may be useful. In other forms suitable size strips can be administered as individual pieces ready-cut for use, for use with or without surgical tape. In other forms a suitable size pieces may be cut from sheets to treat larger and less regular wounds. The application will be varied to suit the wound or tissues to be dressed. The invention has many potential applications, for people and animals for rapid wound healing with minimal lasting scarring, a significant improvement over the art.
