Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to explain the application, but should not be understood as a limitation to the application.

Please refer to Figure 1. This application provides an electrocardiogram drawing method. include:

S10: Receive monitoring data sent by monitoring equipment;

S20: Process monitoring data to generate level data; and

S30: Use the level data to draw a medically significant electrocardiogram on the mobile terminal using the Bezier curve according to a predetermined rule.

Referring to FIG. 2, an embodiment of the present application provides a mobile terminal. The mobile terminal includes a processor. The processor is used for receiving the monitoring data sent by the monitoring device, and for processing the monitoring data to generate level data, and using the level data to draw an electrocardiogram with medical significance on the mobile terminal using a Bezier curve according to a predetermined rule. The mobile terminal can be a consumer electronic device such as a mobile phone and a tablet computer, which is not limited here. The monitoring device may be a wearable smart treatment device, such as a smart bracelet, a smart watch, a smart ring, a smart ECG sticker, and the like.

The embodiment of the present application also provides an electrocardiogram drawing device 110, and the electrocardiogram drawing method of the embodiment of the present application can be implemented by the electrocardiogram drawing device 110 of the embodiment of the present application.

Specifically, the electrocardiogram drawing device 110 includes a communication module 112, a processing module 114, and a drawing module 116. S10 may be implemented by the communication module 112, S20 may be implemented by the processing module 114, and S30 may be implemented by the drawing module 116. In other words, the communication module 112 is used to receive the monitoring data sent by the monitoring device. The processing module 114 is used to process the monitoring data to generate level data. The drawing module 116 is configured to draw an electrocardiogram with medical significance on the mobile terminal using the Bezier curve using the level data according to a predetermined rule.

In the electrocardiogram drawing method, the electrocardiogram drawing device and the mobile terminal of the embodiments of the present application, the monitoring device communicates with the mobile terminal, and the mobile terminal processes the received detection data to obtain data that can be used for drawing patterns, and the data is drawn according to predetermined rules It is an electrocardiogram, which has clinical medical significance and can be provided to medical workers or diagnostic equipment for direct diagnosis of heart health.

Specifically, with the widespread application of electronic technology in the medical field, users can monitor body parameters including heart rate, respiration, blood oxygen, etc. by wearing related electronic devices, and draw patterns or charts to users, and even give abnormal prompts. , In order to facilitate users to seek medical treatment in time when they find abnormalities. Among them, the electrocardiogram can be used to guide the health of the heart, and the consumer electronic equipment used by the user often cannot draw the electrocardiogram. It requires the user to go to the hospital or use more professional medical equipment to perform the electrocardiogram diagnosis, which is not convenient enough, and can be imaged. The drawn equipment does not have a unified standard, so the drawn drawings often do not have medical clinical reference significance.

In this embodiment, the monitoring device communicates with the mobile terminal through a Bluetooth connection, and the mobile terminal can receive the heartbeat monitoring data sent by the monitoring device in real time. In terms of Bluetooth communication, the Bluetooth software development kit or tool library of a third-party supplier is not used, but the mobile terminal directly interacts with the monitoring device for data processing. In this way, the accuracy of the received data and the real-time performance of data reception can be ensured, the monitoring data will not be lost, and the true heart rate can be reflected. The received data can be processed by filtering and packet sticking to obtain level data for pattern drawing. It can be understood that the unprocessed raw monitoring data is usually some digital codes, which are not user-readable, and the processed data is drawn with medical significance, so that medical diagnosis can be made through the drawn pattern.

The predetermined rules refer to the drawing rules of the electrocardiogram in accordance with the medical meaning, for example, including how to set the electrocardiogram drawing, and how to use the level data to draw the electrocardiogram on the drawing.

The Bezier curve is widely used in drawing operations in industry and other fields. In this embodiment, the current heart rate can be accurately drawn by using the Bezier curve.

Referring to FIG. 3, in some embodiments, S20 includes:

S21: Perform filtering processing and/or packet sticking processing on the monitoring data to obtain level data.

In some embodiments, S21 can be implemented by the processing module 114. In other words, the processing module 114 is configured to perform filtering processing and/or packet sticking processing on the monitoring data to obtain level data.

In some embodiments, the processor is used to perform filtering processing and/or packet sticking processing on the monitoring data to obtain level data.

Specifically, the monitoring data sent by the monitoring device is a hexadecimal number, which has no medical significance, while the clinical electrocardiogram records the curve of voltage change over time. Therefore, the monitoring data needs to be processed, so that the monitoring data can become data that can be drawn and has medical significance after processing.

During the processing, the received monitoring data passes through a filter function to filter out dirty data that has no practical meaning, and then the millivolt level data can be obtained. At the same time, due to the high-speed communication between the monitoring device and the mobile terminal, there may be a problem of monitoring data packet sticking. Therefore, data sticking packet processing is required for the data sticking problem that may occur. For example, a complete set of messages starting with aa, ending with 5a and including other data in the middle: aa 00 01 02 03 04 5a, however, during the communication process, the mobile terminal may not receive a complete message, such as It may be a half message: aa 00 01 02 03 04 5a a 01 02. In this case, the message needs to be processed into a complete message information, namely: aa 00 01 02 03 04 5a.

In this way, the accuracy of the monitoring data can be ensured and packet loss will not occur.

Referring to Figure 4, in some embodiments, S30 includes:

S31: Draw a background image with a set size.

In some embodiments, S31 may be implemented by the drawing module 116, that is, the drawing module 116 is used to draw a background image in a set size.

In some embodiments, the processor is used to draw the background image in a set size.

Please refer to Figure 5. Specifically, in clinical practice, the electrocardiogram is recorded on graph paper, which is composed of small grids with a width of 1 mm and a height of 1 mm. The abscissa represents time, and the ordinate represents voltage. Generally, 25mm/s paper speed is used for recording, and 1 small division=1mm=0.04 seconds. The ordinate voltage is 1 small division = 1mm = 0.1mv.

Therefore, in order to make the pattern drawn by the mobile terminal have clinical significance, it is necessary to draw the background image according to the specifications of the medical electrocardiogram coordinate values.

In this embodiment, the background image includes a plurality of square grids with a side length of 5 mm, and each square grid includes 5 sub-grids, that is, each sub-grid is a square grid of 1 mm*1 mm. The frequency at which the monitoring equipment sends monitoring data is 250 data per second, which is a recording speed of 25mm/s. 50 monitoring data are drawn in each square grid, and 10 monitoring data are drawn in each sub-grid. Each millivolt level data height corresponds to the side length of 2 square grids, that is, the ordinate direction is 1mv=10mm, and each small grid is 1mm=0.1mv.

In this way, the background image is drawn in accordance with the clinically used ECG graph paper, so that both the background image and the level data drawn on it have medical significance.

Referring to FIG. 6, in some embodiments, S30 includes:

S32: According to the resolution of the display device of the mobile terminal, determine the correspondence between the sub-cells and the pixels of the display device;

S33: Draw an electrocardiogram on the background image according to a predetermined rule system and level data.

In some embodiments, the processor is used to determine the correspondence between the sub-cells and the pixels of the display device according to the resolution of the display device of the mobile terminal, and to draw an electrocardiogram on the background image according to predetermined rules and level data.

Specifically, for different models of mobile terminal products, the resolution of the display device is generally different. In order to make the electrocardiogram drawn by mobile terminals of different resolutions have a unified medical significance, in this embodiment, the engineering quantity of 1 mm is converted into The number of pixels of the current display device, that is, the length of 1mm that determines how many pixels of the current display device can display, respectively record its coordinate points, and draw.

In one example, the following method can be used to convert the length of the sub-grid to pixels to obtain the width of the display area of the display device and the number of pixels in the width direction, and further calculate the ratio of the two to get the number of 1mm Pixels. In this way, according to the conversion ratio, the level data can be drawn at the corresponding pixel point. In addition, although mobile terminals of different resolutions have different drawing scales, they have the same medical reference significance if they have the same amount of engineering.

Referring to FIG. 7, in some embodiments, S30 includes:

S34: Draw with 50 level data as a group;

S35: Draw a pattern of a set of level data in a square grid at a time;

S36: Drawing patterns from left to right on the display device to obtain an electrocardiogram.

In some embodiments, S34-S36 may be implemented by the rendering module 116. In other words, the drawing module 116 is used for drawing with 50 level data as a group, and for drawing a pattern of a group of level data in a square at a time, and for drawing from left to left on the display device. Draw patterns on the right to get an electrocardiogram.

In some embodiments, the processor is used to draw a set of 50 level data, and used to draw a pattern of a set of level data in a square at a time, and used to display data from the display device. Draw patterns from left to right to get an electrocardiogram.

Specifically, in this embodiment, every 50 level data is a group, and one refresh is triggered. One refresh is the drawing of a segment of the electrocardiogram, and the 50 level data corresponds to one square grid, that is, 5 sub grids. The patterns of each square grid are spliced to obtain an electrocardiogram. In this way, the effect of dynamically refreshing and displaying the electrocardiogram on the current screen can be realized.

Draw from left to right, in line with the medical electrocardiogram drawing method, and also in line with the reading habits of users and diagnosis.

Please refer to FIG. 8. In some embodiments, S35 further includes:

S351: Set multiple level data to a transparent state to obtain a transparent point interval;

S352: Drawing the first sub-pattern of the transparent point interval and the second sub-pattern outside the transparent point interval in a set of level data with the transparent point interval as the boundary;

S353: Display the first sub-pattern in a transparent state and display the second sub-pattern in a physical state.

In some embodiments, S351-S353 may be implemented by the rendering module 116. In other words, the drawing module 116 is used to set a plurality of level data in a transparent state to obtain the transparent point interval, and to draw the first sub-pattern and the first sub-pattern of the transparent point interval in a set of level data with the transparent point interval as the boundary. The second sub-pattern outside the transparent point interval is used to display the first sub-pattern in a transparent state and the second sub-pattern in a physical state.

In some embodiments, the processor is used to set a plurality of level data in a transparent state to obtain the transparent point interval, and to draw the first sub-point of the transparent point interval in a set of level data with the transparent point interval as the boundary. The pattern and the second sub-pattern outside the transparent dot interval are used to display the first sub-pattern in a transparent state and the second sub-pattern in a physical state.

Please refer to Figure 9. Specifically, in actual drawing, in order to identify the current drawing progress and make the user know the current drawing position, set multiple of a set of 50 level data to a transparent state to form a transparent point interval. That is, if the sub-pattern drawn by these points is displayed in a transparent state or not displayed, the user can know the position of the square grid currently drawn.

Taking the transparent point interval as the boundary, the current refreshed set of level data is divided into two parts, the transparent state and the non-transparent state. The sub-patterns of the two are drawn respectively, and the first sub-pattern is displayed in the transparent state, and the second sub-pattern is displayed in the physical state. Sub-pattern. The first sub-pattern and the second sub-pattern are joined together to form the square electrocardiogram pattern.

The number of level data set to the transparent state can be set at the factory, for example, set to 20, that is to say, 20 of the 50 data refreshed each time are in the transparent state, for example, each The first 20 data of the second refresh are set to the transparent state, that is, one square grid is updated each time, and the first two small grids are 40% transparent and the transparent refreshing visual experience is better. Of course, in order to show where to refresh, the number of data in the transparent state can also be set to 25 or 30. There is no restriction here, as long as the user can know the location of the refresh.

From the overall perspective of the ECG, the transparency point interval divides the ECG into three segments, the front, middle and back, and the front segment is an ECG pattern drawn based on all level data before the transparent interval refreshes the position. The middle section is the first sub-pattern drawn by the level data that is currently refreshed to the transparent state. The latter part is the second sub-pattern drawn by the non-transparent state level data among the 50 level data refreshed this time and the pattern existing in the previous cycle.

In this way, through the setting of the transparent interval, firstly, the user can know the current drawing position, and secondly, a new effect similar to dynamic refresh can be achieved, and the user experience is better.

Please refer to FIG. 10. In some embodiments, S36 further includes:

S361: Determine whether the drawing position of the current set of level data exceeds the display range of the display device;

S362: If the drawing position exceeds the display range, draw the level data beyond the display range from the initial position of the electrocardiogram drawing and cover the existing pattern.

In some embodiments, S361 and S362 can be implemented by the drawing module 116. In other words, the drawing module 116 is used to determine whether the drawing position of the current set of level data exceeds the display range of the display device, and when the drawing position exceeds the display range, draw the level beyond the display range from the initial position of the electrocardiogram drawing. Data and overwrite existing patterns.

In some embodiments, the processor is used to determine whether the drawing position of the current set of level data exceeds the display range of the display device, and when the drawing position exceeds the display range, draw the initial position of the electrocardiogram drawing that exceeds the display range. Level data and overwrite existing patterns.

Specifically, in this embodiment, a single-screen drawing instead of scrolling is used, that is, after the current screen has been drawn, the pattern will not be moved forward to leave the last position for the current refreshed level data Draw, but redraw from the initial position of drawing, and overwrite the previous pattern. In order to enable the display device to display multiple squares, when drawing the background image, the display range of the electrocardiogram in a single screen can be set according to the width of the display device.

The storage of the level data of the whole screen is recorded by the array. After every 50 level data refreshes, the level data at the corresponding position of the array is replaced and the pattern is updated. The current refresh location is recorded by the index, and the index is increased by 50 after each refresh. When the index exceeds the display range, the index starts from 0 to record again. In this way, the effect of a single ECG screen without scrolling and dynamic refreshing of new radio waves is achieved.

It should be noted that although due to the limitation of the display range, in the process of drawing the electrocardiogram, the later pattern will cover the previous pattern, but the recording of the level data will not be overwritten, but the electricity refreshed every time. The level data is saved in order, and all the information of the current heart rate monitoring will be saved in the local storage space. After diagnosis, the current monitoring data can be uploaded to the cloud and recorded according to time for future reference.
