Definitions

  • the system called "BODY IMPEDANCE MEASURING DEVICE” is an innovative' equipment devoted to monitor the impedance in different body areas, which works combined to an electric generator for body treatment, and is useful in medical, aesthetic, sports, fitness and veterinary field.
  • the system is endowed of particular characteristics that grant the maximum comfort for the treated subject and the maximum security for the operator in all the work phases.
  • the proposed device is just implemented in radiofrequency devices such as: • Endothermic
  • the human body can be assimilated to an electric bipolar, endowed of resistive, capacitive, inductive effects.
  • Z V/I, where V and I are the complex representation of applied tension and current.
  • Z it's a complex value, which real part Re(Z) will be dependent on the body resistance, meanwhile the imaginary part Im(Z) is in strict dependence with the capacitive and inductive body effects.
  • the measuring is performed, by the procedures that will be specifically i explained next, both for the real part and for the imaginary about the impedance. Practically the Re(Z) (real part of the complex impedance Z) and Im(Z) (imaginary part of the complex Z) reading.
  • the visualisation is effectuated after an elaboration of these values, and can be related to (see picture n. 1):
  • the measuring is performed quantitatively valuing in the absorbed current by the final stage (picture 3).
  • RF GENERATOR is a device that generates electric signals for therapy to which one associates the equipment "body impedance measuring device";
  • the successive block so as to allow: o
  • the real part visualization o
  • the imaginary part visualization o
  • the module visualization o
  • the phase angle visualization o
  • this block allows to put in a desired (logarithmic, exponential, etc%) scale the signal.
  • DATA LOGGER obtains the impedance value at predefined times passed by the signal conditioning block.
  • Memorise it in a memory with suitable dimension and eventually transmit informations to the user interface; video graphic/ printer,
  • VISUALISATOR PRINTER
  • PC various user interfaces to visualize in real time the body impedance value, or to visualize the impedance variation among the time;
  • TREATMENTS EXIT parts in contact with the patient's/user's body (electrodes, handles, etc.);
  • FEEDBACK gives to the Generator RP the instantaneous value (but not necessarily) instantaneous of body impedance. In this way it can be implement into the RP Generator a system to keep the current or the exit tension (or a combination of this) constant.
  • This system can be realised almost in two forms: o Automatic control microprocessor: the system regulates the generator power in an automatic way. The user formulate some initial parameters, then the microprocessor automatically of the power of the regulation, in the regulation power, to keep constant the chosen value ( current, tension or o something else) .
  • o Powered handle control the system behaves in the same way of the previous, moreover the power regulation handle of the RF generator is enlivened by an electric starter in agreement with the variation power.

Abstract

Dispositif de mesure d'impédance corporelle permettant de déterminer l'impédance de différentes zones du corps, et en particulier les variations d'impédance inhérentes à plusieurs facteurs comme l'utilisation de matériel électromédical radioélectrique. On vise à mesurer, mémoriser et visualiser (par indicateur numérique ou analogique à impression). Le dispositif permet d'améliorer considérablement l'efficacité de traitement, et l'opérateur peut constamment surveiller l'état des tissus traités à travers l'impédance. Enfin, le dispositif procure un confort optimal à la personne traitée et garantit une sécurité maximum à l'opérateur dans toutes les phases de travail.
