[0009]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the wristband-type measuring device 100 according to the first embodiment of the present invention is connected to a wristwatch so that a person to be measured can wear it by hand. The arm-band type measuring device 100 includes a main body 10, a first contact portion 20, a second contact portion 30, a central processing unit 40, and a display screen 50.

The main body 10 includes a shell 11 of a wristwatch and a two-band body 12 connected to both sides of the shell 11. The shell 11 has a bottom surface 13 and a top surface 14, a time window 15 indicating time by a numeral at a fixed position on the top surface 14, and a battery (not shown) is provided inside the shell seat 11. The electric power necessary for the measurement of the armband type measuring instrument 100 is supplied.

The first contact portion 20 has a first contact 21 made of an electrode piece, and the first contact 21 is fixedly provided on the bottom surface 13 of the shell seat 11. The first contact point 21 is in direct contact with the skin of the hand when it is carried by the hand (left hand) of the person. The second contact portion 30 also has a second contact point 31 similarly formed of an electrode piece. The second contact point 31 is fixedly provided at a fixed position on the top surface 14 of the shell seat 11, and when the finger of the hand (right hand) of the subject presses the second contact point 31, the arm band type measuring instrument 100 and the second contact point 31 The measurer forms a circuit and the person to be measured is considered a capacitor.

A central processing unit 40 is installed inside the shell seat 11, and the central processing unit 40 is electrically connected to the respective contacts 21 and 31. The central processing unit 40 has a measurement unit 41 composed of many electronic components, a comparison unit 42, and a calculation unit 43. Referring to FIG. 3, a measurement unit 41 is used to sensitively measure input and output signals at the first and second contacts 21 and 31 of the circuit, and collect and organize the input and output signals.

The comparison unit 42 is a built-in program of the central processing unit 40, and can compare and compare with input and output signals and sort it. The calculation unit 43 detunes the above compared signal. A display screen 50 is provided on the top surface 14 of the shell 11, and the display screen 50 is electrically connected to the central processing unit 40. After receiving the signal processed by the central processing unit 40, the measurement result is displayed in a digital system.

[0014] The measurement principle and use of the first embodiment of the present invention will be described by taking body fat content measurement as an example. The human body is composed of muscles, bones, blood and the like, and the tissues contain water. In terms of conductivity, the human body can be considered a capacitor. When the first contact 21 and the second contact 31 simultaneously contact the skin of the hand part (right hand and left hand) of the subject, current flows from the first contact 21 via the conductive tissue of the human body to the second contact 31. And each contact constitutes one capacitive load.

[0015] Electrical resistance occurs in a capacitor during conduction and charge / discharge of a circuit. This electrical resistance is the non-conductive portion of human body tissue (eg, body fat), and the electrical resistance and capacitance values are inversely proportional in the circuit, that is, the higher the body fat content of the human body, the greater the resistance. The charge and discharge time of the capacitor is shorter because the capacitance value is smaller, and conversely, if the body fat content of the human body is smaller, the charge and discharge time of the capacitor is longer because the capacitance value is larger. Become.

In normal times, as shown in FIGS. 4 and 5, the arm-band type measuring instrument 100 having the time window 15 is used as a general wristwatch. When trying to measure the body fat content in the human body at hand, using the above principle, the second contact point 31 is pressed with the finger of the unarmed hand of the arm-band type measuring instrument 100 at the same time. The first contact 21 is in contact with the skin of the hand. At this time, a portion in contact with the first contact 21 and the second contact 31 forms one capacitive load.

Referring to FIG. 6, the central processing unit 40 sends out several signals having different frequencies within a fixed time (several seconds) from the start of measurement, and the measuring unit 41 simultaneously outputs signals of different frequencies at the subject. The input and output signals at the contacts 21 and 31 of the (condenser) and the charge / discharge time are measured. All signals are integrated to obtain an average value, and the integrated signal is compared and compared with the comparison unit 42. Finally, the signal compared and compared by the calculation unit 43 is converted into a number and displayed. When the human body fat content rate is displayed at 50, the measurement operation ends. This has convenience.

As shown in FIGS. 7 and 8, an arm-band type measuring device 200 according to a second embodiment of the present invention is also applied in combination with an arm clock. Since the structure is the same as that of the first embodiment, the structural features of the armband type measuring device 200 and the operating principle thereof will be described here. A two-electrode piece is fixedly provided on the bottom surface 202 of the shell 201 of the wristwatch. Each electrode piece forms a first contact 60. A two-electrode piece is also provided at a predetermined position on the top surface 203 of the shell seat 201, and the second contact 70 is formed. The central processing unit 80 is installed inside the shell 201, and includes a signal amplifier, an analog / digital converter, a voltage stabilizing circuit, a microprocessor, and the like. At the time of measurement, each second contact 70 is simultaneously pressed with two fingers (the index finger and the middle finger) of the same hand of the subject. Since the first contact point 60 is in contact with the skin of the hand, the arm-band type measuring instrument 200 forms one electric circuit with the subject, and the subject is regarded as one electrical resistance.

When a weak and harmless electric current flows through the human body, it passes through non-conductive tissue (eg, body fat) and consumes power. Therefore, a signal sensed from each contact point is output from the central processor. After being transmitted to 80, converted, determined, and calculated, it is finally displayed numerically on the display screen 90 installed on the top surface 203 of the shell 201.

The wristband-type measuring device of the present invention is applicable by being combined with an object (for example, a wristwatch) that can be worn by hand, and maintains its original function (displaying time) as it is, while maintaining human characteristics. It can also be used to measure values (eg, body fat content). It has many functions in use and is convenient for measurement, and certainly has advanced practicality. The embodiments described above are only preferred embodiments of the present invention, and all structural changes having the same effect as the present invention are included in the claims of the present application.
