Definitions

  • the present invention relates to a fixing system for a biomedical electrode. More precisely, it relates to a fixing system for a biomedical electrode comprising elastic snap-on fixing means.
  • the electrode consists of a flexible element of planar shape comprising an adhesive face, intended to ensure the fixing of the electrode to the skin of a person, and a face provided with a male conducting element.
  • Each electrode is associated with a cable provided at one of its ends with a female element intended to receive the aforementioned male element.
  • the present invention aims to improve the connection between the male element and the female element, this in particular in order to obtain better mechanical strength, better conduction between the electrode and the cable as well as to facilitate the positioning of the element.
  • female on the male element during their fixing aims to improve the connection between the male element and the female element, this in particular in order to obtain better mechanical strength, better conduction between the electrode and the cable as well as to facilitate the positioning of the element.
  • an assembly comprising a biomedical electrode, a cable and elastic snap fastening means intended for fixing said electrode to said cable, said fastening means comprising a male element and a female element, characterized in that the male element has an orifice and the female element has a protuberance, the latter being shaped to be housed in said orifice when the two elements are fixed.
  • the male element is disposed on the electrode while the female element is located on one end of the cable.
  • the fixing system is identical to those of the state of the art described above. It differs, however, in that the male element has an orifice on its upper face and in that the female element has in its cavity a protuberance intended to be housed in the orifice of the male element once the two elements are attached to each other.
  • a fixing system is preferably chosen, characterized in that the male element comprises a first portion of substantially frustoconical shape, located on the side of the female element, disposed on a second portion of substantially frustoconical shape, inverted relative to the first portion.
  • the angle formed by the side wall of the first portion is less than the angle formed by the side wall of the second portion.
  • the angle formed by the side wall of the first portion is between 5 ° and 15 ° and that the angle formed by the side wall of the second portion is between 30 ° and 50 ° .
  • a particularly advantageous configuration is obtained when the angle formed by the side wall of the first portion is substantially equal to 8 ° and when the angle formed by the side wall of the second portion is substantially equal to 40 °.
  • the invention also relates to an electrode as described above as well as a cable provided with a female plug as described above.
  • Figure 1 illustrates an assembly comprising an electrode, a cable and fixing means.
  • Figure 2 shows a section of the male element and the female element separated from each other.
  • Figure 3 shows a section of the male element and the female element fixed to each other.
  • a flexible electrode 1 of planar shape is provided on its upper face with a male element 3.
  • the latter (see also Figure 2) consists mainly of a first part 6 of form frustoconical and a second part 7 also frustoconical in shape but inverted relative to the first part.
  • An orifice 5 is arranged on the upper face of the male element.
  • the female element 4 comprises a cavity 8 intended to surround the male element 3.
  • the interior of the cavity 8 comprises a stud 9, preferably constructed of a conductive material.
  • the stud 9 is in close contact with the walls of the orifice 5 of the male element 3.
  • the angle a defined between the vertical and the side wall of the upper portion 6 of the male element 3 is less than the angle ⁇ defined between the vertical and the side wall of the lower portion of the male element 3.
  • the invention is not limited to a particular form of electrode.
  • the choice of materials and the geometry of the different elements is not limited to what has been described in the example discussed above.
  • the invention is also not limited to a particular field of use. Preferably, it targets the field of muscle electrostimulation but it can also find an application elsewhere, for example for the establishment of an electrocardiogram.
