Definitions

  • the present invention relates to orthopaedics and more particularly to an improved method of manufacturing custom-made arch supports and anatomic insoles.
  • the known methods of manufacturing arch supports provide for taking the footprint by plastic pastes (plasticine), foams and/or plaster casts.
  • the positive form, on which the arch support will be moulded, is made in such cases by casting plaster or rigid polyurethane foams into the negative footprints.
  • One problem of the known art is given by that such methods necessarily make use of disposable materials which increase the cost.
  • a long processing time is requested in order for the plaster or the plastic material to be allowed to set completely as well as the moulds and the moulding tools stained with plaster to be cleaned.
  • a method filed by the same Applicant which consists of taking the footprint and manufacturing the positive moulds which are suitable for moulding custom-made arch supports without using disposable materials. Such a method has the drawback of necessarily using different devices for the several manufacturing steps.
  • a first object of the invention is therefore to overcome all of the problems of the known art by providing a method of taking a negative footprint and manufacturing positive moulds by which custom-made arch supports can be moulded in a particularly easy fashion.
  • a second object of the invention is to provide means that puts the above method in practice and are of simple construction and easy usability.
  • a third object of the invention is to provide means for putting in practice the above method which can be used both for taking negative footprints and manufacturing positive moulds.
  • the method to be described provides two means 5, one for taking negative footprint 1 of the patient and one for manufacturing positive mould 2 on which the moulding of the custom-made arch supports has to be made, and sealing means 7 to be put temporarily between the first two means for obtaining positive footprint 2 after having taken negative footprint 1.
  • a first peculiar characteristic of said means 5 is that they are exactly the same even if they can be used from time to time for taking negative footprints 1 and moulding positive moulds 2, which reduces advantageously the production costs.
  • a second peculiar characteristic of the invention is that each means 5 has a very simple construction. In fact such means consists essentially of a sealed bag, preferably of latex or other material, which can be easily deformed and that contains granular material 6 such as sand and is capable of taking the patient's footprint.
  • Such a bag 5 is closed by a gas sealing tap 4 which is can be connected to a vacuum pump.
  • a deformable bag 5 which is used as a means for taking footprints RI
  • the shape that it takes because of the weight borne by the patient's foot which has been put thereon is kept and made stable and sturdy enough by the fact that tap 4 communicating with the inside of the bag is connected to a vacuum pump which sucks in all of the air from the inside of bag 5.
  • granular material 6 inside bag 5 is compacted and keeps the same shape that it had previously taken.
  • Upper bag 5 is capable of being deformed so as to develop positive mould 2 corresponding to negative footprint 1 in lower bag 5.
  • said sealing member 7 consists essentially of a ring of a very soft elastic material which is capable of fitting in and sealing tightly the contour of both overlapped bags 5.
  • Such a sealing function is very important in order to allow all of the air between the two overlapped bags 5 to be sucked in, thus causing the upper bag to become deformed and to take on a "positive" shape 2 corresponding to negative footprint 1 of lower bag 5.
  • sealing ring 7 is provided with an intake pipe connected to a quick-coupling connector 4B outside the ring and provided with an open end 9 projecting inside the ring.
  • a weight 3 has a flat lower face so that upper bag 5 used as moulder of positive moulds FP has no depressions or protrusions which could hinder the manufacturing of the arch supports that follows.
  • the method herein described includes essentially the following steps:
