Definitions

  • the invention relates essentially to a method and an apparatus for supporting an element to be supported, in particular a body of a patient, allowing support at a controlled depth of penetration.
  • a device for supporting an element to be supported, in particular the body of a patient, generally mainly known as a mattress, is well known.
  • Such a device comprises, in certain cases, at least one closed chamber or with controlled, flexible exhaust, inflatable under a pressure as a function of the maximum driving-in distance authorized in the support of the element to be supported.
  • filling or evacuation means are provided for filling or inflating said chamber until the depression is brought back below the maximum authorized insertion distance.
  • the sensor of this measuring device is based on the principle of the coupled circuit presenting an indirect electromagnetic coupling (of the transformer type) and variable, function of the distance separating the primary and the secondary from the coupled circuit (see figure 5 in appendix).
  • a fixed frequency oscillator delivers constant energy to the primary of a transformer which transfers variable energy to the secondary of this transformer as a function of the distance separating the primary and the secondary from the transformer.
  • This energy collected at the transformer secondary is delivered to an amplifier.
  • the invention also aims to solve the new technical problem set out above, so as to provide a solution which improves the distribution of the weight of the body of a patient to allow a therapeutic application of the support device, so that the pressure local does not prevent blood circulation, to avoid the formation of bedsores.
  • the support device comprises a sensor, the principle of which is based on the variation of the self-induction coefficient of a coil, a fully-fledged element of an oscillator.
  • This variation in the self-induction coefficient is obtained by varying the distance separating a metal sheet located under the element to be supported, such as the body of a patient, and the coil.
  • This variation as a function of the depression of an element to be supported, such as the body of a patient, moves the resonance frequency of the LC circuit away from the tuning frequency of the oscillator and therefore results in a damping of the signal delivered to the amplifier by the oscillator.
  • the present invention provides a method of supporting an element to be supported, in particular the body of a patient, comprising the provision of at least one support device comprising at least one closed or controlled, flexible, inflatable exhaust under an adjustable initial inflation pressure, said chamber having an upper face and a lower face, means for controlling the inflation pressure of said chamber as a function of the insertion distance into the device support for the element to be supported comprising means for filling or evacuating a fluid for filling said chamber under said pressure and means for measuring the distance (D) separating the upper face of the chamber relative to the face lower, characterized in that the initial inflation pressure of said chamber is controlled at a driving distance adapted so that the element to be supported, and in particular the body of a patient, sinks deep into the support device, bringing said upper face of said chamber to a predetermined distance (D c ) of relatively small set point vis-à-vis the underside of said chamber, and in that the upper face is maintained during the support of the element to be supported, in particular the body of

  • the aforementioned measuring means comprise on the one hand a metallic element, advantageously in the form of a thin sheet, placed under the most prominent or heaviest part of the element to be supported, in particular the body of a patient, integral with the upper face of the chamber, cooperating with at least one inductive device forming position detector integral with the underside of said chamber, in particular by being placed under the underside of said chamber.
  • the desired insertion at said set distance from the element to be supported has the consequence of obtaining a pressure of between 4 and 40 mbar.
  • the principle of detection of the depression of the body to be supported is fundamentally different from the principles of the prior art.
  • the distance separating the upper face from the lower face of the chamber is kept essentially constant at said set distance during the duration of the support of an element to bear, especially the body of a patient, and whatever its weight, position, morphology and, more precisely, its morphological profile. This ensures the best possible distribution of the weight on the upper face of the chamber used for the support.
