Embodiment 1

[0020] like figure 1 As shown, the constant current drive circuit 104 outputs a constant current signal of 500 Hz to 500 kHz and is connected to the electrode 102 on the surface of the computer keyboard. When the finger of the user 101 touches the electrode 102, the impedance signal (voltage) obtained by the electrode 102 passes through the impedance The signal amplifier 103 amplifies, and then transmits to the analog-to-digital conversion 106 through the isolation circuit 105, after being converted into a digital signal, the CPU microcontroller 108 transmits it to the PC computer 111 through the communication interface 1110, and then displays the composition on the screen of the computer 111, according to the The measured tissue components provide medical and health care suggestions to the measured person, or send the tissue components to doctors or hospitals through the network according to the operator's wishes. The DC / DC power supply 107 supplies power to the circuit befor...

Embodiment 2

[0024] like figure 2 As shown, the constant current drive circuit 104 outputs a constant current signal of 500 Hz to 500 kHz to the electrode 102 installed on the surface of the computer keyboard. When the finger of the user 101 touches the electrode 102, the impedance signal (voltage) obtained by the electrode 102 passes through Impedance signal amplifier 103 amplifies, transmits to analog-to-digital conversion 106, and then transmits to CPU microcontroller 108 through isolation circuit 105 after being converted into a digital signal, and then transmits to PC computer 111 through communication interface 110, and then displays the organization on the screen of computer 111 According to the measured tissue components, medical and health care suggestions are given to the subjects, or the tissue components are sent to doctors or hospitals through the network according to the operator's wishes. The DC / DC power supply 107 supplies power to the circuit before the isolation circuit,...

Embodiment 3

[0028] like image 3 As shown, the constant current drive circuit 104 outputs a constant current signal of 500 Hz to 500 kHz to the electrode 102 installed on the surface of the computer keyboard. When the finger of the user 101 touches the electrode 102, the impedance signal (voltage) obtained by the electrode 102 passes through Impedance signal amplifier 103 amplifies, transmits to analog-to-digital conversion 106, and then transmits to CPU microcontroller 108 after being transformed into a digital signal, and then transmits to PC computer 111 through isolation circuit 105 and communication interface 110 in turn, and then displays the organization on the screen of computer 111 According to the measured tissue components, medical and health care suggestions are given to the subjects, or the tissue components are sent to doctors or hospitals through the network according to the operator's wishes. The DC / DC power supply 107 supplies power to the circuit before the isolation cir...

Abstract

Wherein, it arranges two electrode piece on keyboard surface and an amplifier and data acquisition system in keyboard. During application, the product can measure and display issue component on computer screen, and presents medical and health advice, or by user wish sends data to hospital or doctor. This invention is benefit to people using computer frequently.

Description

technical field [0001] The invention relates to a peripheral device of a computer, in particular to a computer keyboard capable of measuring human tissue components. Background technique [0002] Modern life and work make more and more people in a sub-health state, manifested in obesity or abnormal weight loss, calcium deficiency or mineral loss, and electrolyte disorders, but due to various reasons, it is difficult for people to go to the hospital for regular checkups Physically, cardiovascular patients tend to ignore their physical condition before they have obvious symptoms. At present, with the rapid development of computer and network technology, computers and the Internet have increasingly become indispensable equipment in people's work, study and life. The computer has a powerful data processing function. After being connected to the Internet network, the computer can be used to detect the physiological signals of the operator, so that the tissue components can be de...
