Definitions

  • the current invention relates to an improvement of a flexible sheet as described in WO 2007060273 for a sheet with valve-controlled pressure system that allows mechanically and visually assessing pressures.
  • the invention proposes making subsequent moulds of this flexible sheet and the subsequent use mostly for medical purposes, which can mitigate any risks to the skin of its wearer.
  • the invention also relates to a method for the development of an insole for the sole of the foot, using said flexible pressure sheet obtained from a surface with protrusions and valleys that record the plantar pressure after walking.
  • the sole of the foot presents alterations, mostly produced by excessive, repetitive pressures in some parts of the said sole.
  • the device of this invention provides, through a fast, simple, mechanical procedure, firstly, a view of how the footfall of a subject under study is created and, after a number of cycles of walking or stepping, in the footstep left, a number of valleys are visible, corresponding to areas of maximum repeated impacts, and a number of high areas are also identifiable, wherein the foot is not supported or hardly is.
  • a qualified technician in the art can obtain, with a quick glance, the view of a good approximation to the average of the dynamic plantar pressures in the different areas of the sole of the foot for each person measured; the sheet being susceptible to being automatically reused later again.
  • a negative cast can easily be obtained, high areas in this negative corresponding to areas of maximum impact and very thin areas corresponding to areas of low or zero support.
  • the material used for the negative cast is normally of low hardness and excellent memory. With methods used frequently in the market (by chiropodists, orthopaedists, prosthetists, etc.), for instance with the use of silicone, this negative cast can be kept in the medical record of the subject under study.
  • this sheet with cavities is, in many cases, the generation of a final insole that the subject will later use to compensate for the excessive pressures.
  • this compound sheet (soft plus hard) can be used in many subjects under study as a final insole and, in some cases, at least do as a final insole for its metatarsal areas.
  • the device of this invention is a sheet 1 provided on its top with a number of cavities 2 adjoined or close to one another and linked together by means of a captive circuit through which a fluid of known density circulates.
  • This hollow and closed circuit with the circulating fluid is usually in the lower portion of the said sheet or the adjoining cavities.
  • the slow transfer of fluid between the cavities occurs in a significant manner: Through the resistance presented by the passageway surface of the holes and ducts, as well as the length of the said ducts, which can be tubes, channels, sieves or any grooves 3 acting as a brake to the viscosity of the fluid.
  • Cavities receive the pressures 6 ( FIG. 1 ) of the sole of the foot from their upper side.
  • a predetermined pressure When, in one of the cavities, a predetermined pressure is exceeded, its fluid is transferred between adjacent cavities, increasing or decreasing the volume of the said cavities in inverse proportion to the pressures experienced by the different cavities from their upper side.
  • the deformation of the volume of the different cavities is mostly in the vertical direction, both upwards and downwards.
  • the fluid is transferred from some cavities to adjacent ones; when the foot sways again, the heights and the volume of the cavities become stable; that way, cavities that have received strong pressures have had their volume reduced, and the height of adjacent cavities wherein the pressure has been smaller or become zero will be increased, since they have received a part of the transferred fluid.
  • the cavities with the holes, channels, sieves, tubes or grooves are occupied in captive form by a fluid, which contacts and occupies all that volume and from which some volume has previously been subtracted after drawing in the air and part of the fluid, achieving this thanks to the flexibility of the cavities; this allows any chamber that barely receives pressure to rise more than in its original situation of equilibrium, so the areas that did not support or press get closer to the sole of the foot, thereby giving stability and support to the insole to be developed later.
  • the objective is to obtain a plantar footstep assessable to the naked eye that is the average of the pressures produced by the footfall of a person's foot, after walking with the flexible sheet for some time, and then to be able to reuse it automatically on another person.
  • the mould or negative cast can be obtained directly from the said footprint produced by each person. For instance, we add liquid silicone and wait for its quick setting. We separate the generated soft foil from the flexible sheet, with which we have the negative cast, which we can keep in the patient's medical record.
  • FIG. 1 A perspective view of a flexible sheet of contiguous or adjoining hexagonal cavities, seeing their upper surface, wherein it receives the different plantar pressures or impacts 6 .
  • the cavities have hexagonal shape and they are joined together by their base.
  • FIG. 2 Layer 1 , situated under the hexagonal cavities it supports, this support being fostered by the circular groove 4 found on the upper side of said layer 1 . Holes 5 connecting the ducts 3 below this sheet with the inlet to the upper cavities. Ducts 3 link adjacent holes and carry a fluid.
  • FIG. 3 A longitudinal sectional view of a tube 3 communicating two contiguous cavities 2 that forms a valve device, supported on a basal layer 1 , here with an elastomeric spring 10 and a number of caps 7 located at both ends of each tube with a number of channels 11 in its inner wall.
  • FIG. 4 A longitudinal sectional view of a tube communicating two contiguous cavities that forms a valve device, here with an elastomeric spring contracted 10 by the action of the internal pressure 9 of the fluid 12 filling it, in one of the directions, by increasing the pressure in one of the adjacent cavities.
  • FIG. 5 A longitudinal sectional view of a tube 3 communicating two contiguous cavities that forms a valve device 13 , here with a metal spring 10 with its spring rod 8 and a spring limit 14 closing with its outside boundary, in contact with the internal boundary of the tube; the flow of the fluid is normally shut off until, due to the intensity of the pressure, this spring limit surpasses the channels.
  • FIG. 6 A longitudinal sectional view of a tube communicating two contiguous cavities that forms a valve device, here with a contracted metal spring 10 with its rod 8 seated on its cap 7 .
  • FIG. 7 A top view of a flexible sheet of contiguous or adjoining hexagonal cavities 2 .
  • five entire ones are partially deployed so they can be better seen, with a central hexagonal cavity with denser cords, and two upper and lower half cavities; from top to bottom, there is the hexagonal cavity, then, below, the sheet with grouped holes 16 in an area and, further the sheet with cords 15
  • the device of this invention is a flexible sheet formed by cavities, sheets, tubes and a captive fluid.
  • Cavities 2 adjoined to one another are supported on a sheet 1 with grooves 4 on its upper side and holes 5 , the latter linking the upper cavities with the ducts arranged under the sheet 4 .
  • the cavities and the channels 3 linking them are occupied by a captive fluid of known viscosity.
  • These cavities receive the pressures 6 of the sole of the foot on their upper side.
  • the deformation of the volume of the different cavities is mostly in the vertical direction, both upwards and downwards.
  • the ducts are generally located under the cavities, their endpoints coinciding under the inlet hole 5 of said cavities.
  • the ducts are located on a laminated polymer or a sole 7 , below.
  • the ducts are made of a material with sufficient strength to withstand intracavity pressures, generally of polymeric materials.
  • Each duct links a cavity 2 with a contiguous cavity 2 , several ducts 3 coming together under one and the same inlet hole to each cavity and they are usually separated within the hollow of the inlet.
  • the flexible sheet With the repetition of this succession of pressures a sufficient number of steps, the flexible sheet will provide a good approximation to the average of pressures in each of the areas; for example, of the sole of a foot after walking, since not always, under similar conditions, is the footprint the same for one person.
  • the objective is to obtain a plantar footstep assessable to the naked eye that is the average of the pressures produced by the footfall of a person's foot, after walking with the flexible sheet for some time, and then to be able to reuse it automatically on another person.
  • a mould or negative cast can be obtained directly from the said footprint produced; the entire insole can even be developed directly from the said mould; on other occasions, the final insole at least of the metatarsal area is obtainable, with subsequent adaptations in the area of the heel, the toes and the plantar arches.
  • the cavities 2 with the holes 5 and ducts 3 are occupied in captive form by a fluid, which contacts and occupies all that volume and from which some volume has previously been subtracted after drawing in the air and part of the fluid, achieving it thanks to the flexibility of the cavities; this allows any chamber that barely receives pressure to rise more than in its original situation of equilibrium, so the areas that did not support or press get closer to the sole of the foot, thereby giving stability and support to the insole to be developed later.
