Definitions

  • the invention relates to a device and a method for ulcer prophylaxis and for the early detection of neuropathy in the diabetic foot.
  • the motor disorder occurs before the sensitive disorder, because the motor skills of the nerves in the muscular area are more likely to be damaged than in the sensitive area, it is possible to detect the onset of neuropathy in a standing test.
  • the object of the present invention is a
  • a device for ulcer prophylaxis and for early detection of neuropathy in the diabetic foot consisting of a measuring surface, such as a pair of soles or a platform with measuring points, the measuring points being pressure sensors, such as integrated pressure sensors from hydro cells with microsensors arranged underneath, and wherein the analog values detected by the pressure sensors are fed to a computer and evaluated there by a program, the measuring points are connected to the computer via preprocessing interface electronics with an analog-to-digital converter and the data are evaluated online by the program, the data being transferred by the interface electronics to the computer via cable or wireless.
  • At least 3, but preferably 16 measuring points are arranged at the anatomically important points on the measuring surface per foot.
  • an electronic visual medium for example a video device with a screen
  • the test subjects are distracted by a film to such an extent that they do not concentrate on standing.
  • requests to the Subjects are given, such as moving.
  • the measuring points are connected by cable to a measuring box to be carried by the test subject, which contains the analog-to-digital converter, filtering means such as depth pass or trigger and / or measured value correction means.
  • the data obtained is stored on a storage medium, e.g. a hard disk or a CD-ROM.
  • a storage medium e.g. a hard disk or a CD-ROM.
  • the pressure sensors can be piezoresitive, capacitive, inductive or resistive sensors.
  • the method according to the invention for ulcer prophylaxis and for the early detection of neuropathy in the diabetic foot contains the steps:
  • Fig. 3 shows a printout of a measurement result
  • Fig. 4 shows a printout of a measurement result
  • the subject 1 stands on two measuring soles 2, each with 16 measuring points.
  • the measurement results are delivered online via cable 3 and a preprocessing interface electronics 4 to the computer 5, where they are evaluated by a suitable program.
  • the subject 1 looks at the screen of a video terminal 6.
  • the computer 5 is connected to the video terminal 6.
  • the hardware structure can look as shown in FIG. 2.
  • the left sole 7 and the right sole 8 are connected by cable to a measuring box 9, which the
  • Converter card passes from where it is in an interrupt routine 12 in the computer 5 with timer 13 and Main memory 14, read in and evaluated there by the main program 15 and finally written to a hard disk 16.
  • the processing in the measuring box 9 can be influenced via a control line.
  • Fig. 3 and Fig. 4 show the different results in subjects without and with clearly diagnosed neuropathy. These are printouts of raw data.
  • the upper curve 18, 18 ' represents the load values of the right foot and the lower curve 17, 17' represents the load values of the left foot.
  • the larger the spaces 19, 19 'between these curves the more frequent and larger the load change between the two Feet. It is easy to see how much these values differ between the two subjects. While the subject shifted their weight continuously during standing in the 15 minutes of measurement without a clearly diagnosed neuropathy, the pressure values in the subject with clearly diagnosed neuropathy are almost the same for both feet over the entire period.

Abstract

Dispositif pour la prophylaxie de l'ulcère et pour le diagnostic précoce de la neuropathie dans le pied d'un diabétique, comprenant une surface de mesure, telle qu'une paire de semelles ou une plate-forme à points de mesure, dans lequel les points de mesure sont des capteurs de pression intégrés se présentant sous la forme d'hydrocellules à micro-capteurs sous-jacents, et les valeurs analogiques détectées par les capteurs de pression sont transmises à un ordinateur où elles sont évaluées par un programme, et dans lequel, en outre, les points de mesure sont reliés à l'ordinateur par l'intermédiaire d'une interface électronique de pré-traitement, dotée d'un convertisseur analogique/numérique, et les données sont évaluées en ligne par le programme, la transmission des données de l'interface électronique à l'ordinateur s'effectuant en mode câblé ou non câblé.
