Description

Sheer Force Negating Plaster

This invention relates to patches and methods of using said patches. More particularly, thisinvention relates to an adhesive plaster type construction that relates to the problem ofblistering and how it can occur to areas of the skin primarily in relation to the foot or areasof the foot that are subject to lateral rubbing of the skin which can cause separation andfluid build up resulting in blistering.

Due to almost all sports or leisure activities that are carried out on hard surfaces wherebecause of lateral movement combined with forced contact to the ground, heat andmoisture and the lateral rubbing affect can quickly result in blistering that not only impedesperformance but can also be very painful during the healing process.

This is an invention that can also be used as a preventative treatment for diabetics whobecause of their illness suffer badly from sores and blisters to their feet that can deteriorateto the point where amputation may be necessary, whereas the sheer force negating plastercan effectively eliminate the extremity of the cause of this problem. '

Existing plasters tend to focus on reducing the possibility of developing blisters by adheringto foot where blistering is likely to occur in hot and moist conditions which tends to result inthe plaster coming away from the vulnerable area leaving the area exposed to blistering.

The sheer force negating plaster is different because it is designed to adhere to the inside ofthe footwear directly to the area the user feels they are likely to be exposed to lateralrubbing which will cause the blistering to develop.

The sheer force negating plaster is also versatile enough so as to be incorporated into otherproducts where blistering is a common problem i.e. gloves, socks or different types of jointprotection.

The sheer force negating plaster is primarily made up in circular form but its shape can varyin size and form in relation to where it is positioned.

If the plaster is positioned in the toe area or the front of the footwear an oblong plasterwith oblong flexible plastic inserts, if the plaster were to be positioned into a curved area onthe side of the shoe an oval shaped plaster with oval flexible plastic inserts.

The top layer of the plaster can incorporate any type of material that would allow a degreeof lateral movement as to allow the two flexible plastic inserts with a gel or similar type oflubricant incorporated between the two flexible plastic inserts to slide laterally, so as tonegate any rub transferring from the footwear to the skin which would cause blistering.

The preferred top layer of material would be a readily available baltex spacer material whichis 2.5mm to 3mm thick but is flexible in its lateral ability which contributes to its maximumeffectiveness of the two flexible plastic inserts incorporating a layer of gel or similar typelubricant in-between the two flexible plastic inserts.

The base layer can be a standard plaster type material or similar type material that wouldallow enough rigidity so as to give the plaster the ability to adhere to the inside of thefootwear but not too thin a material that would allow the plaster to be susceptible to beingforced away from its adhered position due to rubbing against it causing roll up of its edges.

The outside circumference of the plaster would be heat sealed to a width of around 5mm soas to seal the flexible plastic inserts in place so as to allow lateral movement without cuttingand separating the laminated top and bottom layers of the material used to construct thesheer force negating plaster.

This would also act as a tapering of the edge of the plaster so as to seat firmly against thematerial of the footwear so as not to be susceptible to peeling away because of rubbingagainst it by the foot.

The pressure sensitive adhesive base layer applied to the base of the lower later of materialcould vary in strength depending on its various applicable needs, it may not be necessary ifthe plaster was to be incorporated into a glove or a sock but depending on the type offootwear it would probably differ in strength if used in a running shoe as opposed to beused in a leather type football boot due to its effectiveness in negating lateral sheer force insports such as running, football, rugby, tennis, climbing and long distance walking it wouldhave a variety of materials to be considered to which it can be applied.

The invention will now be described by way of example with reference to the accompanyingdrawing in which:

Fig 1 shows a complete sheer force negating plaster.

Fig 2 shows a separated composite makeup of the sheer force negating plaster fig 1 showsthe complete sheer force negating plaster 1, laminated together with a heat sealed 5mm ormore depending on the size of the plaster so as to allow neat firm fixing of the plaster andits peripheral edge so as not to allow rolling up and pulling away.

Fig 2 shows a separated composite make up of the sheer force negating plaster in which thetop layer of material consists of a baltex spacer material 2, which because of its constructionallows a degree of lateral movement so as to compliment the lateral movement of the twoflexible plastic inserts 3,5, although other available materials can also be used so as towiden its variety of applications.

Fig 2 also shows a layer of gel or similar type lubricant 4, in-between the two flexible plasticinserts 3,5, which should be just enough to allow free lateral movement but not too muchso as to allow the plastic inserts to float rather than slide.

The bottom layer of material 6, is a pliable type material which should be stable enough soas to allow a firm adhesion to the inside of the footwear so as to not allow the plaster to rollat the edges and dislodge.

The base is coated with a pressure sensitive layer of adhesive 7, so as to adhere to whatevermaterial the plaster would be applied to.

Claims

1. A shear force negating plaster comprising a patch for contacting a portion of asubject, said patch being a laminate comprising a backing layer having an adhesivecapable of adhering to a substrate and an upper layer for contacting a portion of asubject in use, the patching having at least one moveable member disposed in achamber between the backing layer and upper layer and capable of moving withinthe chamber in response to movement of the portion of a subject in contact with theupper layer, wherein the chamber is fluid filled, wherein the fluid comprises any one or more of the following: water based lubricantgel, oil based lubricant gel or other type of lubricant fluid.

2. A patch as claimed in claim 1 wherein the moveable member comprises any one ofthe following, comprising: circular, square or oblong body.

3. A patch as claimed in any one of the previous claims wherein the moveable memberis resiliently deformable.

4. A patch as claimed in any one of the previous claims comprising two moveablemembers.

5. A patch as claimed in any one of the previous claims wherein the backing layercomprises a woven material.

6. A patch as claimed in any one of the previous claims wherein the substrate is a pieceof footwear.

7. A shoe comprising a patch as claimed in any one of claims 1 to 6.
