Abstract

A plaster may be adhered to the interior of an item of footwear or hosiery, such as a shoe or sock. The plaster may comprise a spacer material layer 2 and a pliable layer 6 which may be coated with and adhesive 7 to allow it to be attached to a shoe. The layers may be laminated together using a heat sealing process and may surround an inner compartment containing gel type lubricant 4 sandwiched between plastic panels 3 and 5. The device may be shaped and sized to allow it to be selectively located in footwear or may be used in clothing such as gloves to prevent blistering.

Description

Sheer Force Negating Plaster

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

Due to almost all sports or leisure activities that are carried out on hard surfaces where because of lateral movement combined with forced contact to the ground, heat and moisture and the lateral rubbing affect can quickly result in blistering that not only impedes performance 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 who because of their illness suffer badly from sores and blisters to their feet that can deteriorate to the point where amputation may be necessary, whereas the sheer force negating plaster can effectively eliminate the extremity of the cause of this problem. ^

Existing plasters tend to focus on reducing the possibility of developing blisters by adhering to foot where blistering is likely to occur in hot and moist conditions which tends to result in the 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 of the footwear directly to the area the user feels they are likely to be exposed to lateral rubbing which will cause the blistering to develop.

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

The sheer force negating plaster is primarily made up in circular form but its shape can vary in 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 plaster with oblong flexible plastic inserts, if the plaster were to be positioned into a curved area on the 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 degree of lateral movement as to allow the two flexible plastic inserts with a gel or similar type of lubricant incorporated between the two flexible plastic inserts to slide laterally, so as to negate 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 which is 2.5mm to 3mm thick but is flexible in its lateral ability which contributes to its maximum effectiveness of the two flexible plastic inserts incorporating a layer of gel or similar type lubricant in-between the two flexible plastic inserts.

The base layer can be a standard plaster type material or similar type material that would allow enough rigidity so as to give the plaster the ability to adhere to the inside of the footwear but not too thin a material that would allow the plaster to be susceptible to being forced 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 so as to seal the flexible plastic inserts in place so as to allow lateral movement without cutting and separating the laminated top and bottom layers of the material used to construct the sheer force negating plaster.

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

The pressure sensitive adhesive base layer applied to the base of the lower later of material could vary in strength depending on its various applicable needs, it may not be necessary if the plaster was to be incorporated into a glove or a sock but depending on the type of footwear it would probably differ in strength if used in a running shoe as opposed to be used in a leather type football boot due to its effectiveness in negating lateral sheer force in sports such as running, football, rugby, tennis, climbing and long distance walking it would have 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 accompanying drawing 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 2 shows the complete sheer force negating plaster 1, laminated together with a heat sealed 5mm or more depending on the size of the plaster so as to allow neat firm fixing of the plaster and its 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 the top layer of material consists of a baltex spacer material 2, which because of its construction allows a degree of lateral movement so as to compliment the lateral movement of the two flexible plastic inserts 3,5, although other available materials can also be used so as to widen its variety of applications.

Fig 2 also shows a layer of gel or similar type lubricant 4, in-between the two flexible plastic inserts 3,5, which should be just enough to allow free lateral movement but not too much so 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 so as to allow a firm adhesion to the inside of the footwear so as to not allow the plaster to roll at the edges and dislodge.

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