Description

TECHNICAL FIELD

The disclosure is directed to obtaining bioelectric measurements using an electrodermal probe in contact with body tissue of a test subject and is particularly directed to methods, systems, and devices for applying and maintaining surface moisture on a test subject to aid in acquiring a consistent ground reference during bio-conductance testing and/or obtaining bioelectric measurements.

BACKGROUND

The electrical conductance of body tissue can be measured and analyzed to gather information about a body's condition and to aid in assessing certain conditions. One form of measuring electrical conductance of body tissue is Electroacupuncture According to Voll (EAV). EAV and other electrical conductance assessment systems measure conductance levels at meridian points of the body. These electrical conductance assessment systems are used by some health practitioners to gain additional insight into a test subject's body make up and condition.

EAV and other electrical conductance assessment systems often utilize an electrodermal probe in contact with the body tissue of a test subject in order to measure and/or test electrical conductance of the test subject's body tissue at meridian points of the body. During measuring or testing of electrical conductance of the test subject's body tissue, EAV and other electrical conductance assessment systems often utilize a grounding device that contacts the test subject to serve as the ground reference in a test circuit formed using the test subject, and the electrodermal probe and grounding device of the electrical conductance assessment system (e.g., EAV).

Meridian points are located under the skin of a test subject which adds to the difficulty in measuring resistance because skin can become dry and act as an insulator instead of a conductor, thereby impeding electrical conductance and compromising accuracy of readings taken of the meridian points of the test subject. To minimize this insulator effect, several methods may be utilized, either alone or in combination including spraying or applying water or other conductive fluid on the portion of the test subjects skin that contacts the grounding device to help increase the conductivity of the test subjects body tissue. Grounding device is the ground or reference in the test circuit.

In light of the foregoing, disclosed herein are systems, methods, and devices for achieving and maintaining surface moisture on the skin of a test subject in order to improve grounding of the test subject's body tissue during electrical conductance assessment testing.

Electroacupuncture According to Voll (EAV) devices may be deployed to measure conductance levels at meridian points in a body. An EAV device is a sensitive ohm meter for measuring resistance in the body. The resistance of a material, tissue, meridian pathway, and so forth can be assessed to calculate the conductivity of the material, tissue, and/or meridian pathway. A material with a lower resistance measurement will have a higher conductivity.

To detect resistance, an ohm meter (such as an EAV device) applies a small direct current flow through a material. Resistance measures the relative difficulty for current to flow through the material. Electrical conductors allow current to flow easily and have a correspondingly low resistance. Electrical insulators restrict current flow through and have a correspondingly high resistance. Ohm's Law applies to materials with a proportional relationship between voltage, current, and resistance according to:

V=IR

where V is voltage (measured in volts), I is current (measured in amps) and R is resistance (measured in ohms). Conductivity is the reciprocal of resistivity, expressed mathematically as 1/R and indicates a degree to which a specified material conducts electricity.

Human tissue generally has a resistance of about 98,000 Ohms between the tissue and ground. Meridian points have a general resistance of about 5,000 Ohms between the meridian point and ground. This means that meridian points throughout the human body are about twenty times more conductive than the tissue surrounding the points. This large differential in conductivity makes it possible to locate meridian points and to be very consistent in verifying the meridian points with an EAV device.

Traditional EAV testing or resistance measuring of meridian points may be done by having a subject grip a metal rod (hand mass or grounding device) in one hand while point measurements are taken on the other hand and the other side of the body with a probe of the EAV device. The metal rod may be placed in the other hand while the points on the other side of the body are read with the EAV device. The point measurements may use an electrically conductive tip to contact the meridian point and the measurements are taken and recorded while pressure is applied to the metal tip against the tissue at that point.

Meridian points are located under the skin which adds to the difficulty of measuring resistance associated with the meridian point because skin can become dry and act as an insulator. To alleviate this insulating effect, spraying a mist of water or other conducting fluid on the hand that grips the hand mass may be done to help increase the conductivity of the tissue that is gripping the hand mass or metal rod. The hand mass acts as a ground or a ground reference in the test circuit of the conductance testing device. Other methods to decrease this insulating effect is to increase the pressure of the tip against the tissue over the Meridian point, to add moisture or water to the tissue where the measurement is taken, and to apply texture to the tip surface that helps penetrate the insulation layer or a cornified layer of the tissue without puncturing.

In some cases, small electrodes similar to those used with EKG machines in the place of the brass rod or hand mass. Additionally, different sized hand masses may be made to fit different sized hands whether they be a small children or large adults. In testing, it was determined that that the grounding or reference surfaces having larger sizes improved the grounding of the test subject and led to more consistent and more accurate measurements.

Metal rods, handles, hand masses, and/or grounding devices are often implemented using brass due to its relatively high conductivity. However, brass may tarnish and become soiled with use by repeated gripping. The tarnishing may be aggravated by continuing to use the same grounding surfaces, hand mass, and testing tips for multiple patients. Continued and repeated use of these metal rods, handles, hand masses, grounding surfaces, grounding devices, etc. may create oxidation and tarnishing and may degrade the conductivity of the grounding surfaces, hand masses, grounding devices, and test tips associated with the system and device. Therefore, the grounding surfaces, hand masses, grounding devices, and test tips may require frequent cleaning to maintain desired conductivity. However, using a non-oxidizing material or a new tip or grounding device for each new patient may help increase patient to patient measurement accuracy and device cleanliness.

Even with clean surfaces or new conductive material, the moistening of the grounding area of the hand or skin portion being grounded may aid in achieving more accurate and more consistent measurements. Moistening of the surface/skin being grounded may be achieved by frequently squirting a mist of water or other conducting fluid on the surface/skin to keep the skin moist. Skilled technicians may identify when measurements from the conductance measuring device seem to be losing accuracy and may then take action remoisten the subject's skin to achieve improved grounding and more consistent measurements during electro-conductance testing of a test subject.

In order to avoid pausing testing to rewet a test subject's skin with a mist or spray, the grounding device described herein may include a moistening media and apertures in a grounding plate that continually moistens the test subjects skin while in contact with the grounding plate. This configuration has an advantage of maintaining moisture on a test subject during electro conductance testing in order to obtain more consistent and reliable conductance measurements without the need to pause a current test.

The following disclosure is a conductive device configured to contact skin of a test subject during bio-conductance testing of the test subject. The conductive device may comprise a first conductive portion that is electrically conductive, one or more apertures formed through the first conductive portion, and moistening media that applies a conductive fluid to the skin of the test subject through the one or more apertures. The conductive device may be a grounding device for grounding the test subject.

As disclosed herein, the conductive device further includes a cover and a base. The cover is configured to alternate between an open position and a closed position relative to the base. The first conductive portion is disposed on the cover. The moistening media is disposed adjacent to the apertures in the first conductive portion of the cover and between the cover and the base. Furthermore, the cover may comprise an openable and closeable compartment for holding the moistening media adjacent to the apertures of the first conductive portion.

The base may comprise one or more second conductive portions. Furthermore, the cover is in electrical communication with the base when the cover is in the closed position and the cover is electrically separated from the base when the cover is in the open position. One or more second conductive portions are disposed on the base such that the one or more second conductive portions contact a palm of a hand of the test subject during the bioelectric testing, and the first conductive portion is disposed on the cover such that the first conductive portion contacts fingers and/or palm of the hand of the test subject during the bioelectric testing. The cover is in electrical communication with the base through a conductive contact on the base that contacts the first conductive portion of the cover. The conductive contact is spring-biased to press against the first conductive portion when the cover is in the closed position.

The base of the conducting device may comprise one or more of a battery to power the conductive device and an electrical connection to receive electricity from an outside power source to power the conductive device.

Part of the disclosure includes a bioelectric testing system for taking bioelectric measurements of a test subject. The bioelectric testing system includes a grounding device for contacting a first portion of a test subject. The grounding device includes a first conductive portion that is electrically conductive and contacts skin of the test subject, one or more apertures formed through the first conductive portion, and moistening media that applies a conductive fluid to the skin of the test subject through the one or more apertures. The system may further include an electrodermal probe for contacting a second portion of the test subject including a probe tip that contacts the second portion of the test subject.

Now referring to the figures, FIG. 1 illustrates a perspective view of a bioelectric measurement system 10, which is an example of an EAV or electrical conductance assessment system. As shown, bioelectric measurement system includes an electrodermal probe 22, grounding device 30 (e.g., a hand mass, or grounding surface), and a bioelectric measurement analyzing device 18 in electrical communication with electrodermal probe 22 and grounding device 30.

Grounding device 30 may include a handheld mass to be held by a test subject undergoing measurements by bioelectric measurement system 10. Grounding device 30 may include a rod made of brass, or any other suitable material for grounding the test subject. Grounding device 30 may include a grounding surface disposed around an exterior of grounding device 30.

Grounding device 30 may be a small electrode similar to those used in conjunction with an electrocardiogram (EKG). Grounding device 30 may be any suitable size or shape and may be formed in an ergonomic size and shape that is easy for a test subject to hold in a palm of the test subject's hand. Grounding surface of grounding device 30 may be of a sufficiently large size to provide ample grounding to take sufficiently consistent and sufficiently accurate measurements from the test subject.

Electrodermal probe 22 is configured to measure the resistance of skin, a meridian pathway in a body, or other materials or tissues. The readings taken by electrodermal probe 22 can be assessed to calculate the conductivity of the skin, the meridian pathway in the body, or other materials or tissues in the body. Electrodermal probe 22 may include a testing end, which may include a probe hood 24 and a probe tip 26 disposed at a distal end, or in other words testing end, of electrodermal probe 22 with respect to the electrical connection with bioelectric measurement analyzing device 18. Probe tip 26 may be placed against the skin of a test subject to enable electrodermal probe 22 to measure the resistance of the skin or meridian pathway in the test subject. The electrodermal probe 22 may take a measurement when probe tip 26 is pressed against tissue. Probe tip 26 may be constructed of any suitably electrically conductive material such as copper, silver, gold, aluminum, zinc, nickel, brass, iron, steel, or other material known to those skilled in the art.

The probe tip 26 may be a single probe tip or the probe tip 26 may include a plurality of individual probe tips. Probe tip 26 may be textured to help penetrate and help electricity flow through the insulation layer or cornified layer of the epithelial tissue without puncturing it. The grounding pads and/or contacts may be integrated with probe hood 24. Electrodermal probe 22 may further include a contact sensor 28 disposed on probe hood 24 to detect proper contact between probe tip 26 and the test subject.

The bioelectric measurement analyzing device 18 may include one or more processors configurable to execute instructions stored in non-transitory computer readable storage media. Bioelectric measurement system 10 may include memory stored locally therein and accessible by bioelectric measurement analyzing device 18. Bioelectric measurement analyzing device 18 is in electrical communication with electrodermal probe 22, grounding device 30, and a display 16. In the illustration shown in FIG. 1, bioelectric measurement analyzing device 18 is in electrical communication with electrodermal probe 22 by way of a sensor connection point 14 and is in electrical communication with grounding device 30 by way of grounding connection point 12. The electrical communication between bioelectric measurement analyzing device 18 and electrodermal probe 22 and/or grounding device 30 can be facilitated by electrically conductive cables 20. Alternatively, the electrical communication may be made wirelessly through a wireless network such as a wireless personal area network (WPAN), a wireless local area network (WLAN), and so forth. Electrically conductive cable 20 may further be connected to a power source such that electrodermal probe 22 and/or grounding device 30 are powered by way of an external power source.

Conductance testing or measuring of meridian points may be done by having a test subject grip a conductive rod or hand mass (grounding device 30) in one hand while point readings are taken on the other hand and or the other side of the body using electrodermal probe 22. Then the conductive rod (grounding device 30) may be placed in the other hand while the point readings are taken on the other side of the test subject's body with electrodermal probe 22. Electrodermal probe 22 may utilize probe tip 26 to contact the meridian points, and the readings may be taken and recorded while pressure is applied against the tissue at that point.

The grounding device 30 shown in FIG. 1 is an example of a grounding device that may be used in conjunction with bioelectric measurement system 10. Several other configurations of grounding devices may be used in conjunction with bioelectric measurement system 10. Multiple embodiments of grounding devices that may be used in place of grounding device 30.

A grounding device 100 is shown and described in FIGS. 1A-1F. Illustrated in FIGS. 1A-1F are top (FIG. 1A), front (FIG. 1B), side (FIG. 1C), bottom (FIG. 1D), perspective (FIG. 1E), and rear/back (FIG. 1F) views of a hinged grounding device 100 in a closed position. As illustrated in FIGS. 1C and 1E, grounding device 100 may include a cover 102 and a base 114. Cover 102 may include a knuckle 104 that engages with a pin 116 on base 114 to form hinge H. With knuckle 104 engaged with pin 116, cover 102 may rotate about pin 116 with knuckle 104 to rotate between an opened and a closed position, which will be described in more detail in the discussion of FIGS. 3A-3C in this disclosure. FIGS. 1A-1F show a configuration of grounding device 100 where cover 102 is in the closed position.

The grounding device 100 may incorporate one or more conductive portions. For example, cover 102 of grounding device 100 may include a grounding plate 108. Grounding plate 108 may have one or more apertures 110 formed therein to allow materials and fluids to permeate through grounding plate 108 of cover 102 to moisten the skin of a human test subject in contact with grounding plate 108. The size and shape of grounding plate 108 is not particularly limited as long as grounding plate 108 is of sufficient size to provide proper grounding for the test subject. For example, grounding plate 108 may be around eight square inches, but may be larger or smaller depending on characteristics of the test subject and/or other circumstances such as, for example, environmental conditions and/or the level of moisture applied to skin of the test subject. Grounding plate 108 may be composed of brass or stainless steel, but it will be appreciated that grounding plate 108 may be composed of any electrically conductive material that allows electricity to flow in one or more direction.

Additionally, grounding plate may further be any mesh screen, perforated metal, porous materials, or any conductive material that allows moisture of a conducting fluid to pass through to a skin surface of a test subject while electrically grounding the test subject.

As shown in various figures of FIGS. 1A-1F, grounding device 100 may include a plurality of conductive portions. One conductive portion may be grounding plate 108 disposed on cover 102. Additionally, one or more additional conductive portions (grounding segments 122A and 122B, which may be collectively referred to as grounding segments 122) may be disposed on base 114. Grounding segments 122 may contact a portion of the palm of the hand such as the heel of the palm. The rest of the hand (e.g., other portions of the palm, and/or fingers) may contact grounding plate 108. The bioelectrical grounding device 100 may include a palm locating rib 120 on the proximal end of a base 114. One or more grounding segments 122 may be disposed distally with respect to a palm locating rib 120. As shown in at least FIGS. 1C, 1E, 3A, and 9, grounding plate 108 and base 114 may be curved to fit a curve of a test subject's hand including the palm and fingers for ergonomic comfort and maintenance of reliable contact between the test subject and the grounding device when testing is carried out.

As shown in at least FIGS. 1A-1F, grounding device 100 may include two conductive portions in addition to grounding plate 108. A conductivity test, which may be separate from the conductance testing done on meridian points, may be performed on the test subject to check conductance levels and/or ground saturation before performing conductance testing on meridian points and/or meridian pathways. The conductivity test may be performed by taking a first measurement between one of the two conductive portions (e.g., grounding segments 122A and 122B) and grounding plate 108. After the first measurement, the other grounding segment 122A or 122B (e.g., the grounding segment not used in the first measurement) of grounding segments 122 may be added in series with the grounding plate 108 to facilitate performing a second measurement. This second measurement may be compared with first measurement to determine a level of ground saturation. If both the first and second measurements are the same, then it may be determined that an adequate ground saturation condition is achieved. If the one of the measurements has a greater conductivity measurement when compared with the other measurement, then adequate ground saturation is not achieved, which could result in inaccurate and inconsistent measurements. This situation may usually be remedied by moistening the grounding hand with more conducting fluid or a mist of conducting fluid sprayed on the grounding hand to help reestablish a ground saturation condition.

Ground Saturation Testing

To better understand and illustrate ground saturation the following test was performed. A large hand mass, which was a brass rod (1 inch diameter×3.4 inches long), was covered with strips of nonconductive tape that wrapped around a diameter or perimeter of the brass rod such that each strip of tape covered five percent (5%) of the brass rod or hand mass. A conductance test was carried out using a test subject gripping the hand mass with a dry hand. With 20 strips of tape on the rod the hand mass was completely covered rendering the entire rod nonconductive. Under these conditions, the system was unable to take a measurement.

Next, a first strip of tape was removed exposing five percent (5%) of the conductive brass rod, which resulted in a successful conductance measurement being taken. The surface area of the brass rod is about ten square inches and each strip of tape covered about 0.5 square inches of surface area on the brass rod. Each strip of tape covering the rod were removed one at a time, thus exposing an additional 0.5 square inches of the brass rod, with a conductance measurement being taken each time a strip of tape was removed. As each strip of tape was removed, the conductivity measurement increased because the ground area increased. At the same time as each successive piece of tape was removed, the successive incremental increase in conductance decreased until the eighth strip of tape was removed and about forty percent (40%) of the conductive area or about four square inches of the brass rod was exposed. With about forty percent (40%) of the conductive area exposed, the conductivity was stable and no longer changing upon testing at the same point. With the conductivity stable, the measurement accuracy then remained the same after this point even as more tape was removed and even until the entire brass was exposed. Accordingly, about forty percent (40%) or about four square inches of the surface area of the brass rod exposed was determined to provide sufficient ground saturation.

Effect of Moisture on Ground Saturation

Additional testing was carried out using the same tape removal test described above. In the additional testing, a test subject gripped the hand mass with a wet hand. The additional testing shows that moisture applied to the skin during conductance testing affected the amount of surface area on the brass rod required to establish sufficient ground saturation. The testing revealed that only about 2.8 square inches of ground area was required to establish ground saturation with a wet hand instead of the about four square inches required for achieving sufficient ground saturation with a dry hand. Accordingly, a lower area was need for ground saturation to be achieved with a wet hand than with a dry hand. A required area for ground saturation may vary from person to person based upon the person's skin conductivity and the other factors, such as age, gender, ethnicity, geography, atmospheric, environmental conditions, and the like.

Accordingly, because adding moisture or a fluid between a hand and a ground provided increased accuracy and ground saturation with a smaller surface contact area, bioelectrical grounding device 100 allows moisture to continually permeate through grounding plate 108 using apertures 110 to moisten the hand throughout the duration of a bioelectric measurement test and conductance testing. The bioelectrical grounding device 100, device 100 may include a brass mesh material as at least part of grounding plate 108 with a moistening media, which may be, for example, a wet sponge applied to grounding plate 108 to supply continual moisture to skin of a test subject through apertures 110 in grounding plate 108 for increasing conductivity and maintaining ground saturation for a duration longer than a typical test period.

Grounding device 100 and or grounding plate 108 may be implemented as a perforated stainless sheet to address bending, forming and cleanliness issues.

Moistening media (shown later) functions to hold water or other conducting fluids to apply continuous moisture to grounded skin of a test subject. The moistening media may be a pad, a sponge, a cloth, towel, rag, or any material suitable for releasing moisture or fluid onto a test subject's skin. Other moistening media may be implemented such as a vaporizer, mister, atomizer, sprayer, dropper, pumps, or other device for dispensing moisture/fluid on to a test subject's skin through grounding plate 108. In testing, the moistening media may be implemented as a compressed type of sponge that is initially 1/16 inch thick. When moistened, the 1/16 inch moistening media expands to approximately ⅜ inch thick, which filled its moistening potential and expanded against apertures 110 in grounding plate 108. Thus, the moistening media expanded through apertures 110 and applied ample moisture to the contacting surface of the hand of the test subject. Many different sizes and types of material may be used to maintain continuous moisture to the skin through apertures 110 and may act as the moistening media. The metal used in testing of grounding plate 108 has a thickness of about 0.024 inch with about 0.08 inch diameter for apertures 110. The open perforation density was about thirty-five percent (35%) leaving about sixty-five (65%) of conductive metal contacting the skin for grounding. It will be appreciated that grounding plate 108 may be made from many electrically conductive materials, having a number of different thicknesses, sizes, and geometric shapes without departing from the scope of the disclosure. Furthermore, apertures 110 may be various sizes, shapes, thicknesses, and perforation density, such that apertures 110 allow sufficient moistening fluid to penetrate grounding plate 108 to moisten the skin of the test subject.

To aid in consistency and cleanliness, moistening media may be a disposable item (e.g., easily removed and replaced by a new moistening media). It is further conceivable that that grounding plate 108 and the moistening media may both be disposable (e.g., one time use items) that are pre-moistened with water or another conducting fluid. The conducting fluid may provide more accurate test results if it is formulated with a suitable PH balance and with a controlled conductivity as to be compatible with human tissue of all types. The conducting fluid may aid in normalizing the tissue conductivity from patient to patient.

The grounding plate 108 may be formed to fit a wide variety of hands comfortably. Grounding plate 108 may also be attached to a cover 102 that may further be attached and detached from the base 114 of bioelectrical grounding device 100. Cover 102 may be made of a rigid structure and may include grounding plate 108 and apertures 110 which allow moisture to be dispersed by the moistening media to the test subject. Cover 102 may be hinged, and attached, to base 114 by at least one knuckle 104, slot 106, and pin 116 (e.g., hinge H). Grounding plate 108 may be implemented with apertures 110 and hinge H on cover 102 such that grounding plate 108 opens in an upward direction to expose moisture compartment (shown in at least FIG. 5A) for easy removal and replacement of the moistening media. In this manner a technician may easily change the moistening media with a new moistening media for each new patient.

The cover 102 may comprise one or more knuckles 104 including a slot 106. Knuckle 104 disposed on cover 102 and slot 106 facilitates removal of cover 102 from base 114. The corresponding base 114 may include a pin 116 that may be secured in position by one or more removal guides 118. As knuckle 104 pivots around pin 116, slot 106 aligns with removal guides 118 and knuckle 104 may slide off pin 116 allowing cover 102 to be separated from base 114 (shown in further detail with respect to FIGS. 3A-3C. Because cover 102 may be removed from bioelectrical grounding device 100, bioelectrical grounding device 100 may still allow moisture to be applied to the moistening media while cover 102 is removed from base 114. Cover 102 may then be placed back onto base 114 in a moistened state to help keep extra unwanted water/conducting fluid from compromising electronics and other integral components.

As illustrated, in step 1102 of method 1100 a test subject's skin (e.g., hand) is placed in contact with grounding plate 108, grounding segment 122A, and grounding segment 122B. As illustrated, in step 1104 of method 1100 a first conductance reading is taken between a first portion (e.g., a left side of a heel of the palm) of the test subject's skin in contact with grounding segment 122A and a second portion (e.g., fingers/upper palm) of test subject's hand in contact with grounding plate 108. As illustrated, in step 1106 of method 1100 a second conductance reading is taken between the first portion (e.g., a left side of a heel of the palm) of the test subject's skin in contact with grounding segment 122A, a second portion (e.g., fingers/upper palm) of test subject's hand in contact with grounding plate 108, and a third portion (e.g., a right side of a heel of the palm) of the test subject's skin in contact with grounding segment 122B which is added in series with grounding plate 108. As illustrated, in step 1108 of method 1100 the first conductance reading is compared with the second conductance reading to determine if the numbers are sufficiently similar or different from each other. As illustrated, in step 1110 of method 1100, if it is determined that the first measurement and the second measurement are different, then that conductivity/ground saturation is insufficient (e.g., not enough moisture is present over the test subject's hand) and the hand or moistening media is remoistened and the conductance testing is repeated. As illustrated, in step 1112 of method 1100 if it is determined that the first measurement and the second measurement are sufficiently similar then it is determined that conductivity/ground saturation is sufficient (e.g., enough moisture is present over the test subject's hand) to carry out further conductance testing on meridian points of the test subject.

Determining whether the first measurement and the second measurement are sufficiently similar may be done by comparing a difference between the first measurement and the second measurement to a predetermined threshold. If the difference is greater than the predetermined threshold then the measurements are different than each other. If the difference is less than the predetermined threshold then the measurements are substantially similar to each other. Any portion of the method illustrated in FIG. 11 and described above may be carried out by one or more processors configurable to execute instructions stored in non-transitory computer readable storage media.

As illustrated, in step 1204 of method 1200 a test subject's skin (e.g., hand) is placed in contact with a grounding plate of grounding device 100 and the moisture on the moistening media. As illustrated, in step 1206, a user takes one or more bioelectric conductance measurements on one or more meridian points of the test subject by contacting the meridian point of the test subject with an electrodermal probe.
