    Method for checking the correct operation of electrodes in electrostimulation garments and device for carrying out said method.
    The present invention consists of a method by which a verification of the state of electrostimulation garments, such as vests or other body adaptation, is obtained, said garments being used in the so-called global EMS.
    Electro-stimulation consists in the application of electrodes in areas of the body through which a certain electric current is passed continuously or cyclically, normally adjustable in intensity, so that this current produces in the muscles to which more or more contractions are applied less intense depending on the intensity that is passed through said electrodes.
    The global EMS acts on 10 or more muscle groups, where more than 300 muscles are stimulated simultaneously, these electrodes are designed by the manufacturer with different shapes and sizes, these being of great importance for the correct distribution of the current to Apply.
    It is common use that the electrodes are arranged on the inside of garments specifically designed for use, so that the location of said electrodes is made to coincide, after wetting, with the area of the skin suitable for the stimulation of certain muscles.
    The garments or electrodes are provided with a connector and wiring to connect to the generator of the impulses of the electric current.
    Depending on the intensity of the current, the time during which the user is subjected to it, and the contact area of the electrode, injuries may occur in the area of the skin in contact with the electrode, particularly burns. The current density per unit area, therefore, will depend on the state of the electrode. If, for example, half of an electrode has no contact because the conductive filaments have broken, the current density in the other half of the electrode will be double generating an uncontrolled muscle stimulus.
    When the clothes are new, the electrodes are in optimal condition, and the entire surface of said electrodes is conductive, transmitting the current to the skin, and to the corresponding muscle.
    Thus, so that the continuous use of the garments does not cause damage to the user, it is necessary that there is a distribution of the current on the entire surface of the electrode, that is, that the current density per unit area is at acceptable values .
    However, due to the movement made in the garments that includes the folding to be stored, folded for transport, the connection and disconnection of the wiring for sanitation and the movement that the user makes with the garment on, the electrodes deteriorate over time, the conductive surface being modified, and therefore the current density and the expected muscle contraction with respect to a certain intensity.
    In a brief survey on the Internet, comments are found in different forums that critically criticize this means of obtaining a high-efficiency exercise in bodybuilding, and not without justification.
    image2
    The alleged reasons, in many cases, are due to the consequence of a malfunction because some of the electrodes are in a state of deterioration. Deterioration is considered in that electrode that does not distribute the current that constitutes the pulse evenly throughout its contact surface.
    The muscular activity, all of it, the one derived from a sedentary activity as much as that determined by a sports practice, generates an isoenzyme called creatinine phosphokinase which is known as CPK (thus it will be named later) whose excess produces in conditions of voluntary muscular practice (career, climbing and other sports practices), an information that through the blood reaches the brain, which informs of fatigue, and requires the muscles less activity or even stop it. It is a natural stimulus against activity.
    In cases where the muscle is activated by an electrical impulse, there is also a generation of said CPK isoenzyme, and yet the fatigue that can occur in other practices does not imply a reduction in activity, since the electrical impulse causes the muscular activity according to the programming, that is, the reception of electrical impulses, and not of the will of the one who receives said impulse.
    In controlled electromusculation, practiced by means of safety parameters, and stability criteria, more CPK isoenzymes are produced than those that could occur in any of the voluntary activities due to the large number of muscles that are stimulated simultaneously. Therefore, it is especially important that the coach has adequate training and precise control over the stimulus applied, so that a session and his rest do not constitute a particularly damaging event, nor does it pose a health risk.
    The problem arises when the coach applies more intensity than is convenient, or when the electro-stimulation garment, which is provided with electrodes formed by a micro-wire fabric of filaments, deteriorates, that is, that part of the conductive mesh of the fabric of Filament microgrids are disconnected from the circuit, thus increasing the current density in the rest of the electrode mesh.
    In these cases, the programmed setpoint intensity, intended for a certain current density at each electrode, does not vary, because the corresponding control unit "does not know" that there is a deterioration. However, the current density increases locally, even very significantly, so that the area to be electrostimulated has a different surface, with a different current density, and with a different muscle contraction than desired.
    This error can occur, as for the point of application, and can occur as a difference between two symmetric twin electrodes: left and right part in the same garment, so that if one of them has partially deteriorated conductive tissue and the symmetric acting it will correctly produce burns at best, but at worst, a need to raise the setpoint intensity to reach the intended stimulus levels.
    It should be borne in mind that electromusculation electrodes have their performance in two parts of the muscle, usually at the motor point and in the belly of the muscle, hence the shape and size that the manufacturer uses in the design of each electrode. A poor distribution of the active conductive mesh results in a lack of control in the impulse with the aforementioned consequences, since overstimulation arises when the intensity must be raised to generate muscle contraction through the conductivity of the added moisture, and in the part This need does not occur symmetrically, generating a greater contraction and, consequently, a decompensation in muscular work that would increase the CPK levels released by the electrode stimulated muscle that worked properly.

    The present invention consists of a method for checking the correct operation of electrodes in electrostimulation garments, designed to solve the problem described, this part not knowing any known method for capturing by means of a test the correct state of operation of electrostimulation electrodes, beyond mere manual checking (by resting your hand on the electrode to feel the electrical impulse).
    Through this method proposed by this invention, possible transmission defects are detected in electrostimulation electrodes, particularly in electrostimulation garments, determined if they are suitable for use, and if not, warning of the need for repair. or withdrawal from use.
    The present invention allows the identification of the operating conditions of said electrodes, without risk to the users or the electrodes themselves.
    The present invention also consists of a device for carrying out the method indicated above. Prior art
    Different types of garments are provided with electro-stimulation electrodes, particularly vests or elastic suits, but no means have been described by which a malfunction of the electrodes can be identified, nor a possible detection of excess CPK isoenzyme, whose Consequences can affect the brain and kidneys, as it is described in different articles on this isoenzyme.
    There is, in addition to checking with the palm of the hand, a crude practice for checking the condition of the electrodes, which consists in introducing the tips of an electric tester or tester through the protective cloth of the garment, a fabric that insulates direct contact of the electrode mesh. This practice has two adverse consequences, a first one is that the placement of the tips of the tester tends to cause the breakage of filaments and the progressive and irreversible deterioration of the electrodes tested, and a second is the lack of reliability of the result obtained, since that if a satisfactory reading is not obtained, the tendency is to rummage with the tip of the tester in the place that is being measured until the reading is obtained, so that the tester's tip can simultaneously break a filament and bridge it giving a correct reading.
    The operation test of an electrostimulation garment is also currently carried out by means of the test system, in which an expert person places the garment and proceeds to its activation. If at your discretion, obviously subjective, the test is satisfactory, it is delivered for use. This practice is unfortunately very unreliable, and also unfeasible in gyms where they have a few hundred garments, which would require a very long time for verification, economically unfeasible, as well as unfeasible in practice, because a person cannot be continuously activating by electromusculation because it would incur the same problem that is intended to be avoided.
    Nor is this practice possible for different garment sizes, as it would require so many people to test how garment sizes would be available.
    In a simpler way, as indicated above, it can be verified by the hand of the trainer who, after wetting the electrodes, checks if there is reception of the electrical impulse. This practice does not allow to verify if the electrical impulse exists occurs in a single point or is distributed in the entire surface of the electrode.
    image4 Explanation of the invention.
    The present invention consists of a method for checking the correct operation of the electrodes of an electrostimulation garment, by detecting the conductivity of the conductive tissue on its entire surface quickly and effectively.
    The method comprises:
     Establishment of reference values for a type garment, following the steps indicated below; These reference values may be checked periodically by means of a new "reference" test; Y
     Performing the measurement of the values of the tested garment, and its comparison with the reference values.
    The stages that are carried out are the following:
     Connection of an electric pulse generator to the electrode or garment connector;
     Generation of an electric pulse;
    o The electrical pulse is one of the following types (sinusoidal, rectangular, Faradic, triangular, progressive, ...); in particular it is sinusoidal.
    o The maximum voltage of the electric pulse will be the minimum that of a correct reading result; it has been proven that a value of 9V gives a reliable result; however, any value of the electric voltage that meets the object of the invention must be considered within its scope; o Also, it has been proven that a frequency of 100Hz to 500Hz generates values that provide reliability to the reading; also, any value above or below these that meets the intended purpose must be considered within the scope of the invention;
    The use of these parameters, well below the usage parameters, up to 180V, means that no deterioration should be considered due to the tests;
    The voltage and frequency applied under these parameters causes the electrodes to generate a radio field;
     Application of a receiver, provided with a sensor or antenna, either from the front (outside) of the garment, or from the back (the inside surface); in order to avoid the electrical conductivity between the electrode and the sensor or antenna, said sensor or antenna is preferably provided with an insulating coating to the current, but permeable to the radio field, the application of the sensor or antenna must be carried out dry;
    image5
     Measurement of the values of the radioelectric field emitted by the electrode at different points of the surface of said electrode, or continuously along the surface of the electrode, or of all the electrodes of the garment;
    In the test phase, it also includes the step of comparing the test values with the reference values.
    If the values of the radioelectric field obtained in the test are within a predetermined acceptable range in relation to the reference values the garment or electrode will be valid and may be used; on the contrary, if the electrode or at least one of the electrodes of the garment are outside said range, the electrode must be rejected, and the garment, if necessary, repaired or removed.
    The measurement should preferably be performed dry, to avoid the electrical conductivity and the current flow that would alter the measurement and provide erroneous values.
    The electrodes and / or garments will be correctly identified, for example, by means of a control label provided with an identification code or number. This allows to determine the age of the garment or electrode, the amount of uses made, the evolution of the variation of values with respect to those of reference, and ultimately facilitate the decision to make the repair or rejection even when the measured parameters are to the limit of the acceptable range, that is, very close to the unacceptable.
    The invention also relates to a device for testing according to the method described above.
    The device comprises:
     A transmitter or power supply of a pulsating electrical signal.
     A connector of said source to be connected to the connector of an electrode or a garment provided with electrodes;
     A receiver provided with a radio field sensor or antenna reading at different points of the electrode or continuously along the surface of the electrode;
     A field strength meter read by the receiver.
    Preferably, the collector is provided with an insulating coating of the electric current, but permeable to the radio field.
    According to an embodiment of the above method, a hanger or table can be used as a support for the garment, the measurement being carried out manually in the areas provided with the electrodes. And since it is also possible to verify on the external side of the garment, in a timely manner when the user perceives something strange, you can go to measure the stimulus in the corresponding part, being able to discard the garment at that time if the error has arisen or failure so ensured.
    In addition to this manual device, which checks the electrodes independently, it is planned to perform one that allows simultaneous testing, in which the receiver is constituted by a pick-up dummy to which the garment is placed and attached, being in this case the dummy a collector with multiple catchment areas; The dummy may be provided with an insulating coating on all or part of its surface.
    image6
    In particular, the dummy is compressible and / or is provided with expansive means, for example, by means of a core or an inflatable coating, which ensures a correct positioning of the sensors or antennas with respect to the corresponding electrodes, so that when the The surface of the dummy is located at a minimum distance from the electrodes of the garment.
    The fact that the dummy is compressible or expansive allows it to be used for different sizes without altering the measurement values.
    In this way the verification task is simplified and by placing an air circulation device inside it can also be used to accelerate the drying of residual moisture after its use in the athlete, also improving the hygienic conditions of the garment .
    According to one option, the device can be connected to a computer, so that the readings made in each garment are stored over time, allowing to know its history and evolution of its degree of deterioration. Brief description of the drawings
    In order to illustrate the explanation to be followed, we attach to the present specification six sheets of drawings in which eight figures represent, by way of example and without limitation, the essence of the device of the present invention according to an embodiment particular, and in which:

    According to a first aspect of the invention, a method is described that allows to verify the correct operation of electrodes in electrostimulation garments. According to said method, the following operations are performed:
     Connection to the connector or to the garment connectors of an electrical source.
    image7
     Where appropriate, placing the garment on a test stand.
     If the test stand is a compliant dummy is described as a device of the invention, fastened of the garment on said dummy and expansion of the dummy until the sensor elements thereof are in contact with the electrodes of the garment; otherwise, manual placement of the reading device (the antenna) of the invention on each of the electrodes.
     Generation of an electric pulse that transmits current to the connected electrodes, and generates a radio field in the area of each electrode.
    o The maximum voltage of said electric pulse is up to 9V, although the use of another value will remain within the object of the invention as long as it fulfills the intended purpose;
    or the frequency of the electric pulse is up to 500 KHz and more particularly up to 100 Hz; as in the case of tension, the use of a higher value is also within the scope of the invention as long as it fulfills the intended purpose;
     Application on the external surface of the electrodes, either on the front, or on the back of the garment, of a radio frequency sensor or antenna, which reads the signal of the electric field generated by the electrical source.
     Comparison of the reference values;
    o The reference values will be differentiated according to current measurement, and reference measurements made outside the garment (through the tissue that separates the electrode sensor), or according to current measurement and reference measurements;
     Determination of whether the garment is in the correct state, or if it is in the wrong state and must be repaired or if it should be discarded.
    To avoid that the garment and / or the electrodes can acquire different conductivity conditions due to the humidity and to alter the uniformity of the results, it is recommended that the test be carried out with the dry garment.
    Each garment will have a "token" of calibration, and of the acceptable values, be it the reading made from the inside (in contact with the electrode) or from the outside (through the fabric that forms the garment). Thus, the method of the invention comprises a previous general stage of calibration of each type garment, and establishment of the reference values and / or acceptable values, both on the inside and on the outside.
    Also beforehand, each of the items being tested is identified by means of the corresponding control means (RFID, coded textile label, ...).
    Optional, but conveniently includes the method of the invention the registration of the values obtained for the garment to record its traceability, to know not only the current state, but to track that will allow to assess the quality of the piece, its duration, the evolution of its deterioration, etc.
