The first electrocardio electrode 3 and the second electrocardio electrode 4 can be PET2 electrode plates, silica gel self-adhesive electrode plates or button self-adhesive electrode plates. Wherein the terms first, second, third, etc. are used to denote names, and not to denote any particular order.
For example, when the user uses the writing device, he or she can hold the writing pen 2 with his or her right hand, and when he or she writes with his or her right hand, his or her fingertip contacts the first and second electrocardiograph electrodes 3 and 4 on the writing pen 2, and his or her left hand is placed at the third electrocardiograph electrode 7, and the first, second and third electrocardiograph electrodes 3, 4 and 7 collect electrocardiograph signals of the body surface and transmit the electrocardiograph signals to the electrocardiograph collection module, and the electrocardiograph collection module performs operations such as signal amplification and filtering processing on the received electrocardiograph signals, so as to collect the potential difference of the electrocardiograph signals of the body surface recorded under the writing state of the user.

Further, fig. 5 shows a circuit diagram of a central electrical acquisition module according to some embodiments, and in order to better illustrate the circuit operation principle of the central electrical acquisition module, the address sources of fig. 5 selected in this embodiment are: http:// www.21ic.com/dianlu/med/2015-05-18/625279.Htm, because the first electrocardio electrode 3, the second electrocardio electrode 4 and the third electrocardio electrode 7 collect weak biological signals on the body surface of the human body, a signal collecting circuit needs to be designed to process the collected biological signals to obtain physical signals which can be processed. The signal acquisition circuit is an electrocardio acquisition module in the embodiment. Wherein, electrocardio collection module includes: the pre-amplifier circuit, the filter and the main amplifier circuit, of course, the circuit design can be modified according to actual needs, and this embodiment is only one possible embodiment. The pre-amplifying circuit is used for accurately collecting weak electrocardiosignals from a human body and reducing interference signals, and the pre-amplifying circuit adopts a differential amplifying structure because the electrocardiosignals belong to differential signals. The electrocardiosignals output by the pre-amplifying circuit also contain larger direct current components, electromyographic signals, baseline drift and other interference components, and the useful electrocardiosignals to be acquired need to be controlled within a certain frequency, so that a filter with reasonable design is needed to make the signals within the range fully pass through, and the signals outside the range are attenuated to the maximum extent. The amplitude of the electrocardiosignal is about 0-4 mv, and the electrocardiosignal can be amplified by about 10 times by the pre-amplifying circuit, so that the electrocardiosignal needs to be further amplified for better processing of the electrocardiosignal, and therefore, the electrocardiosignal needs to be amplified by 800-1000 times by the main amplifying circuit. Thus, the amplified accurate electrocardiosignal can be obtained after passing through the electrocardiosignal acquisition module.
In some embodiments, an electrocardiograph processing module electrically connected with the electrocardiograph acquisition module is further arranged on the writing board of the writing device, wherein the electrocardiograph processing module is used for reading electrocardiograph signals from the electrocardiograph acquisition module and performing electrocardiograph signal processing. The electrocardio acquisition module transmits the acquired electrocardio signals to the electrocardio processing module, and the electrocardio processing module receives and reads the electrocardio signals and processes the electrocardio signals to form an electrocardio graph.
Here, the electrocardiograph processing module includes, but is not limited to, a single-chip microcomputer, DSP, PLC, such as Stm32 single-chip microcomputer. For example, in some embodiments, an electrocardiograph processing module of Stm32 is adopted, the electrocardiograph signal of the body surface obtained by processing and recording by the electrocardiograph acquisition module is filtered and amplified to obtain an electrocardiograph signal which can be processed by Stm32, and the electrocardiograph signal which can be processed by Stm32 refers to: the amplitude of the human body surface electrocardiosignal is 0-4V, and the input voltage of the AD converter in the Stm32 is required to be 3.3V, so that the Stm32 singlechip can process the acquired human body surface simulation electrocardiosignal and amplify the acquired human body surface simulation electrocardiosignal by 800-1000 times. Stm32 processes the electrocardiosignals read from the electrocardiosignal acquisition module, sets A/D sampling frequency through a timer, and processes the obtained electrocardiosignals in a mean value filtering mode to obtain connection curve information of potential differences which are traced according to time sequence. For example, the design of processing electrocardiosignals of the chip Stm32 is adopted in http:// www.elecfans.com/dianlutu/187/20151283659. Html.
Of course, those skilled in the art will appreciate that the above described electrocardiographic processing module is merely exemplary, and that other electrocardiographic processing modules that may be present in the present application or in the future are also within the scope of the present application and are incorporated herein by reference.
In some embodiments, the writing device is further provided with a display module connected with the electrocardio processing module, and the display module is used for reading and displaying electrocardio information processed by the electrocardio signals from the electrocardio processing module. For example, a display module connected to an electrocardiograph processing module is provided on a writing tablet or pen of the writing device, and the electrocardiograph information may include, but is not limited to, electrocardiograph waveforms and/or text information, such as some simple text prompt information, for example, a heart rate value. Here, the display module includes, but is not limited to, a liquid crystal display, an LED display screen.
For example, as shown in the display module 5 of fig. 1 and 2, the display module 5 receives the electrocardiographic curve information obtained after being processed by the electrocardiographic processing module and presents the electrocardiographic curve information in the form of an electrocardiographic waveform chart. For example, an electrocardiogram corresponding to the current user is presented on the screen of the writing device.
Of course, those skilled in the art will appreciate that the above display modules are only examples, and that other display modules that may be present in the present application or in the future are applicable and within the scope of the present application and are incorporated herein by reference.
In some embodiments, a power module for supplying power to the electrocardiograph acquisition module is further arranged on the writing board of the writing device. Here, the power module includes, but is not limited to, a dry battery, a button battery, or a USB charging interface. In other embodiments, the power module may also be used to power the display module.

In some embodiments, the writing pen of the writing device is connected to the electrocardiograph acquisition module through two insulated wires, and the two wires respectively realize the electrical connection between the first electrocardiograph electrode, the second electrocardiograph electrode and the electrocardiograph acquisition module. The first electrocardio electrode and the electrocardio acquisition module and the second electrocardio electrode and the electrocardio acquisition module form a circuit through the lead, so that current is transmitted through the circuit, and potential difference signals on the body surface of a human body can be transmitted to the electrocardio acquisition module through the circuit.
For example, as shown in fig. 1,2 and 3, the lead wire 6 connects the first electrocardio electrode 3 and the electrocardio acquisition module and the second electrocardio electrode 4 and the electrocardio acquisition module respectively.
In some embodiments, the connection between the leads on the pen and the electrocardiograph acquisition module is detachable.

In some embodiments, the theme of the writing pad employs an insulating material. The insulating material can play a role in insulating and conducting electricity, and prevents interference of the third electrocardio electrode to collect body surface electric signals due to the conducting effect. For example, insulating materials include, but are not limited to, PC boards, 3240 epoxy boards, silicone boards, and the like.
In some embodiments, the writing board is further provided with a clamp for clamping the paper.
For example, as shown in fig. 1 and 2 for the clamp 8, the clamp 8 may be a coil clamp or a straight plate clamp. The clamp 8 has a fixing function on paper, and can well prevent the paper from moving or falling.
