Referring to FIG. 1, the bioimpedance measuring apparatus 100 according to an embodiment includes a body portion 110 and a plurality of electrodes 121 to 124.

The body portion 110 accommodates the measurement circuit and includes a grip that can be gripped by hand. For example, the body portion 110 may be gripped by an examinee corresponding to a measurement object or an examiner performing bio impedance measurement of the examinee. The measurement circuit is connected to the plurality of electrodes 121 to 124 to measure the bioimpedance of the measurement object. Also, the measurement circuit may determine the body composition (eg, body fat amount) of the measurement object based on the measured bioimpedance.

The plurality of electrodes 121 to 124 may include one or more pairs of current applying electrodes and one or more pairs of voltage measurement electrodes. The bioimpedance measuring apparatus 100 applies a predetermined current using electrodes for applying current among the electrodes 121 to 124 that are in contact with the measurement object, and uses the voltage measuring electrodes to determine a potential difference in a path through which the current flows. By measuring, the bioimpedance of the measurement object can be measured. For example, the bio-impedance measuring apparatus 100 may apply a high-frequency current generated by a built-in current source from one point of a measurement object to another point, and the applied current (current flowing through the body) and current The bioimpedance of a measurement object may be measured based on measuring a potential difference between two points in a flowing path.

The plurality of electrodes 121 to 124 may rotate the first axis 131 or the second axis 132 for stable contact with the measurement object. The first shaft 131 or the second shaft 132 may be provided on one axis of the body portion 110 and have different positions. The first shaft 131 and the second shaft 132 may include an elastic body therein. The first electrode 121 and the third electrode 123 that orbit the first axis 131 and the second axis 132 may be closed at a predetermined angle when the measurement object is not approached and contacted by the elastic body included therein. You can keep it. The elastic body may use a general spring, but is not limited thereto, and if the measurement object approaches and does not come into contact, the first electrode 121 and the third electrode 123 can be maintained at a predetermined angle, and any material is used. Can also be used.

The first electrode 121 and the second electrode 122 may rotate the first axis 131, and the third electrode 123 and the fourth electrode 124 may rotate the second axis 132. Although described in detail below, the first electrode 121 and the third electrode 123 may be opened or collected according to the circumference of the measurement object when the measurement object approaches and contacts. For example, when a measurement object having a circumference greater than a reference value approaches and contacts, the first electrode 121 and the third electrode 123 may be opened. Conversely, when a measurement object having a circumference smaller than the reference value approaches and contacts, the first electrode 121 and the third electrode 123 may be collected.

When the measurement object approaches and contacts the second electrode 122 and the fourth electrode 124, it is pressed by the measurement object and pivots toward the grip, so that the measurement object touches the second electrode 122 and the fourth electrode 124 The depth measurement object can be accommodated more than when starting. Further, the second electrode 122 and the fourth electrode 124 may be supported by the elastic body to restore the position to be measured before the turning of the object to be measured. At this time, the degree to which each of the second electrode 122 and the fourth electrode 124 pivots toward the grip may be the same or different from each other depending on the shape of the measurement object.

In addition, the measurement circuit is the degree to which the second electrode 122 turns toward the grip, the degree to which the fourth electrode 124 turns toward the grip, and the degree to which the first electrode 121 is opened or collected while the measurement object approaches and contacts And the third electrode 123 may be estimated by using at least one of the extent of the opening or gathering. The bio-impedance measuring apparatus 100 may determine the body composition of the measured object without a separate device based on the measured bio-impedance of the measured object and the estimated circumference of the measured object. However, the bioimpedance measurement device may be interlocked with other devices to further increase the precision and accuracy of body composition measurement.

At least one of the bioimpedance, body composition, and body composition of the measurement object determined by the bioimpedance measurement device 100 may be displayed on the display 130.

In addition, according to an embodiment, a pressure sensor may be further provided in the bioimpedance measuring apparatus 100. For example, at least one of the plurality of electrodes 121 to 124 may include a pressure sensor on one side of the electrode. However, the position of the pressure sensor is not limited to this, and any position suitable for measuring the pressure applied to the corresponding electrode as it is in close contact with the examinee is possible without limitation.

For example, a pressure sensor may be included in the second electrode 122 and the fourth electrode 124 positioned at the center. When the second electrode 122 and the fourth electrode 124 contact the examinee, the second electrode 122 and the fourth electrode 124 may be drawn inward, and at this time, the second electrode 122 and the fourth electrode As the pressure sensor disposed on one side of the electrode 124 is pressurized, it is possible to determine whether the test subject is in contact with the electrode and whether the electrode presses the test subject at a pressure required to accurately measure impedance. The second electrode 122 and the fourth electrode 124 may include an elastic material on one side or inside. With the elastic material, when the subject is pressed in close contact, the corresponding electrode is drawn inward, pressure is transmitted to a pressure sensor disposed on one side of the electrode, measured, and after the pressure measurement and impedance measurement are finished, the subject is removed from the electrode. Inside, the pressure sensor can be restored to its initial state before being pressed.

The pressure measured by the pressure sensor can be provided to the subject. For example, the measured pressure can be displayed on the display 130. Alternatively, the measured pressure may be indicated by a pressure gauge or LED light. If the proper pressure is not applied to the impedance measurement, a message may be displayed to inform the testee that the contact was not made properly. For example, if the measurement value of the pressure sensor is smaller than the predetermined first threshold pressure, a message may be provided to the testee that pressure needs to be applied with a greater intensity. Alternatively, if the measured value of the pressure sensor is greater than a predetermined second threshold pressure, a message may be provided to the testee that pressure needs to be applied with a smaller intensity.

The bioimpedance measuring apparatus 100 may be configured to automatically measure the impedance of the test subject when it is determined that an appropriate level of pressure is applied based on the measured value of the pressure sensor. For example, the bioimpedance measuring apparatus 100 may determine that an appropriate level of pressure is applied when the measured value of the pressure sensor is equal to or greater than a predetermined threshold pressure. Alternatively, the bioimpedance measuring apparatus 100 may determine that an appropriate level of pressure is applied when the measured value of the pressure sensor falls within a predetermined threshold range.

For convenience of description, in FIG. 1, four electrodes are exemplarily illustrated, but in addition, various electrodes may be applied to the bioimpedance measuring apparatus 100 without limitation.

Referring to FIG. 2, the display 130 according to an embodiment may include a first button 210, a second button 220, a liquid crystal unit 230, and an LED lamp 240.

The first button 210 may be a zero point button that initializes existing measurement data. By clicking the first button 210 before performing a new measurement, the existing data can be initialized.

The second button 220 may be a mode conversion button capable of mode conversion between a plurality of modes including a first mode for measuring the bioimpedance of the measurement object and a second mode for measuring the circumference or length of the measurement object. have. However, according to an embodiment, when the measurement object approaches and contacts a plurality of electrodes, the bioimpedance and circumference of the measurement object may be determined at one time without mode conversion, and in this case, the mode conversion function may not be used.

The functions of the first button 210 and the second button 220 are not limited to the above-described embodiment, and may be used without limitation as a button for executing various functions required in the bioimpedance measuring device.

The liquid crystal unit 230 may display whether the measurement object is correctly contacted with a plurality of electrodes, the bio impedance of the measurement object, the circumference, body composition, and body composition. In addition, various information that can be displayed on the bioimpedance measurement device can be displayed without limitation on the liquid crystal unit 230.

The LED lamp 240 may display information about a state in which at least one of the bio impedance and the circumference of the measurement object is measured. For example, whether the plurality of electrodes are contacted while applying the correct pressure to the measurement object may be displayed on the LED lamp 240. In addition, various information may be displayed on the LED lamp 240 without limitation.

Referring to FIG. 3, a charging/communication terminal 310 and a magnetic body 320 may be provided on a rear surface of a body part according to an embodiment. The charging/communication terminal 310 may electrically connect an external power supply and a bioimpedance measurement device when charging the bioimpedance measurement device, and connect communication between the external device and the bioimpedance measurement device when communicating with an external device. I can do it. The magnetic body 320 may be for preventing the bioimpedance measurement device from being easily separated when mounted in a separate charger.

Referring to FIG. 4, an exemplary situation is shown when the measurement object 410 approaches and contacts the plurality of electrodes 121 to 124. In FIG. 4, it is assumed that the circumference of the measurement object 410 is greater than a reference value.

When the measurement object 410 approaches and contacts the plurality of electrodes 121 to 124, the second electrode 122 is pressed by the measurement object 410 and pivoted toward the grip so that the measurement object 410 is the second electrode The depth measurement object 410 may be accommodated more than when it starts to reach the 122. The fourth electrode 124 is adjacent to the second electrode 122 and is pressed toward the grip by being pressed by the measurement object 410, and measures more depth than when the measurement object 410 starts to contact the fourth electrode 124 The object 410 may be accommodated.

In order to measure the bioimpedance of the measurement object with high accuracy, it is necessary for the plurality of electrodes 121 to 124 to contact the measurement object with an appropriate pressure. Therefore, it is necessary to determine whether or not at least one of the second electrode 122 and the fourth electrode 124 is pushed by turning to the limit toward the grip, and the bioimpedance measurement result is invalid if it is pressed by turning to the limit. It can be judged as.

Further, the second electrode 122 and the fourth electrode 124 are independent electrodes, and the degree to which the fourth electrode 124 turns toward the grip may be different from the degree to which the second electrode 122 turns toward the grip. have. However, when considering the shape of the measurement object to which the bioimpedance is measured, the bioimpedance when the difference between the degree to which the second electrode 122 turns toward the grip and the degree to which the fourth electrode 124 turns toward the grip is equal to or less than a predetermined threshold. The measurement result can be judged effectively. For example, if the difference between the degree to which the second electrode 122 turns toward the grip and the degree to which the fourth electrode 124 turns toward the grip does not normally contact the measured object 410, the living body It is determined that the impedance measurement result is not valid, and a message indicating re-contact may be output. Thus, it is possible to effectively prevent occurrence of deflection pressure that is too biased to one side due to wrong contact.

5 shows an example of measuring the bioimpedance at the waist portion 510 of the measurement object according to one embodiment, and FIG. 6 is an example of measuring the bioimpedance at the arm portion 610 of the measurement object according to one embodiment. 7 is shown, an example of measuring the bioimpedance in the thigh portion 710 of the measurement object according to an embodiment is illustrated.

According to one embodiment, the measurement circuit provided in the bio-impedance measuring apparatus 100 is the degree to which the second electrode turns toward the grip while the measurement object approaches and contacts the plurality of electrodes, and the fourth electrode turns toward the grip It is possible to estimate which part of the measurement object is being touched using at least one of the degree to be performed, the degree to which the first electrode is opened or collected, and the degree to which the third electrode is opened or collected.

For example, in the case of FIG. 5 in which the bioimpedance is measured at the waist portion 510 of the measurement object, the upper portion of the waist portion 510 of the measurement object is doubled when the back portion is generally flat while the belly portion is convex. The part may be represented, and the lower part may represent the back part. When the bioimpedance is measured at the waist portion 510 of the measurement object as shown in FIG. 5, the difference between the degree of the gap between the electrodes located on the belly side of the measurement object and the degree of the gap between the electrodes located on the back side of the measurement object among the first and third electrodes Is generated, and based on the difference, the measurement circuit can be estimated to be touching the waist portion of the measurement object.

At this time, the estimating apparatus may compare the degree to which the first electrode is opened and the degree to which the third electrode is opened to determine which part of the right side and left side of the measurement object is touching. For example, if the degree to which the first electrode is opened is greater than the degree to which the third electrode is opened, the measurement circuit may determine that it is touching the left flank of the measurement object. Conversely, if the degree to which the third electrode is opened is greater than the degree to which the first electrode is opened, it can be determined that the measurement circuit is touching the right flank of the measurement object.

In addition, in the case of FIG. 5, a difference may occur between the degree to which the electrode located on the ship side of the measurement object turns toward the grip and the degree of the electrode located on the back side of the measurement object turns toward the grip among the second and fourth electrodes. Based on the difference, it can be estimated that the measurement circuit is touching the waist portion of the measurement object. In addition, the estimation apparatus may compare the degree to which the second electrode turns toward the grip and the degree to which the fourth electrode turns toward the grip to determine which part of the right side and left side of the measurement object is touching. For example, if the degree of rotation of the fourth electrode is greater than the degree of rotation of the second electrode, the measurement circuit may determine that it is touching the left flank of the measurement object. Conversely, if the degree of rotation of the second electrode is greater than the degree of rotation of the fourth electrode, the measurement circuit may determine that it is touching the right side of the measurement object.

That is, according to this, the accuracy and accuracy of the impedance measurement can be improved because it is in contact with the subject at a constant pressure by the spring regardless of the shape or thickness of the subject and the measurement part.

The angle adjustment unit 10 may be applied to be connected to the sample unit 1100a according to the first embodiment and the sample unit 1100b according to the second embodiment, but is not limited thereto. It is also applied to be connected to the sample portion of the embodiment to adjust the angle of each segment member or each electrode, the angle of the sample member, or the radius of curvature by the angle adjusting unit 10.

The angle adjusting part 10 is only one embodiment of the adjusting means for adjusting the angle between each segmented member of the sample part 1100, and the sample without the angle adjusting part 10 according to each embodiment of the sample part 1100 as described above The angle of each segment member or electrode of the sub 1100, the angle of the sample member, or the radius of curvature may be adjusted.

14A and 14B, it can be seen that an angle formed between each segmented member of the specimen 1100 varies according to a body shape or a measurement part.

Referring to FIG. 14A, as the body shape or the measurement part is relatively thin, the first segment member 1110 and the second segment member 1120 of the measuring device according to an embodiment of the present disclosure have a first angle (

1) can be achieved.

Referring to FIG. 14B, as compared to FIG. 14A, the body shape or the measurement area is thicker, and a second angle formed by the first segment member 1110 and the second segment member 1120 of the measuring device according to an embodiment of the present disclosure (

2) is the first angle (

It can be seen that it is increased compared to 1).

The rotation coupling part 1050 coupled with the sample part 1100 may further include an angle sensor.

The angle value between each segmented member that is rotated by the angle sensor included in the rotation coupling unit 1050 can be measured, and through this angle value, the circumference, length, or size of the measurement site can be grasped. The shape of the measurement site can be grasped.

15A, the length measurement unit 1200 may serve to measure the circumference or length of the subject. The length measuring unit 1200 may be rotatably coupled to the other end of the body 1000. The length measurement unit 1200 may rotate around a rotation axis passing through the other end of the body 1000. At this time, the rotating shaft may penetrate the other end of the body 1000 vertically or horizontally, but the through direction is not limited to this, and the rotating shaft may penetrate the other end of the body 1000 in any direction, and the length measuring unit ( 1200) may rotate around this axis of rotation.

Referring to FIG. 15B, the length measurement unit 1200 may include a central portion 1210 and an outer portion 1220.

The central portion 1210 may have a hollow disc shape, but is not limited thereto, and may have any shape, for example, a square plate or a hexagonal plate. The material of the central portion 1210 may be made of PC ABS or POM, but is not limited thereto, and any known material may be used.

The outer portion 1220 may have a protrusion formed on the outer surface. The outer portion 1220 may have a donut shape and may be fitted with the central portion 1210. The outer portion 1220 may directly contact the subject to measure the circumference or length of the measurement portion. The material of the outer portion 1220 may be made of silicon, but is not limited thereto, and any known material may be used as long as the length measuring unit 1200 provides sufficient friction with the subject so that it does not slide and slide on the surface of the subject. It is also possible.

The length measuring unit 1200 may perform rolling operation on a part of the surface of the subject. The length measurement unit 1200 may measure the circumference or length of the subject based on the number of revolutions measured by including an encoder therein. For example, if the length measuring unit 1200 is rolled by the circumference or length of 1/2 of the measuring unit, twice the circumference or the length value calculated based on the number of revolutions of the length measuring unit 1200 is the total of the measuring unit. It can be circumferential or length. However, referring to FIG. 16, when the subject is not a rigid body when measuring the circumference or length of the subject by the length measuring unit 1200, the subject is pressed by the elasticity of the subject. Simply applying double does not yield an exact circumference or length. Therefore, it is possible to more accurately measure the total circumference or length of the subject by multiplying the appropriate correlation coefficient obtained by the experiment according to the total circumference or the elasticity of the subject according to the length and the amount of fat.
