The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
Referring to fig. 1, the present application provides a method for mapping an electrocardiogram. The method comprises the following steps:
s10: receiving monitoring data sent by monitoring equipment;
s20: processing the monitoring data to generate level data; and
s30: and drawing a medically significant electrocardiogram on the mobile terminal by using the Bezier curve according to a predetermined rule by using the level data.
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 equipment, processing the monitoring data to generate level data, and drawing a medically significant electrocardiogram on the mobile terminal by using a Bezier curve according to a preset rule by adopting the level data. The mobile terminal may be a mobile phone, a tablet computer, or other consumer electronics device, which is not limited herein. The monitoring device may be a wearable intelligent treatment device, such as a smart bracelet, a smart watch, a smart ring, a smart electrocardiogram patch, and the like.
The present embodiment also provides an electrocardiographic drawing device 110, and the electrocardiographic drawing method of the present embodiment can be realized by the electrocardiographic drawing device 110 of the present embodiment.
Specifically, the electrocardiographic rendering device 110 includes a communication module 112, a processing module 114, and a rendering 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 monitoring data sent by the monitoring device. The processing module 114 is used for processing the monitoring data to generate level data. The rendering module 116 is configured to render a medically significant electrocardiogram at the mobile terminal using the bezier curve according to predetermined rules using the level data.
According to the electrocardiogram drawing method, the electrocardiogram drawing device and the mobile terminal, the monitoring device is communicated with the mobile terminal, the mobile terminal processes received detection data to obtain data which can be used for drawing patterns, and the data are drawn into the electrocardiogram according to the preset rule, so that the electrocardiogram has clinical medical significance and can be provided for medical workers or diagnosis equipment to be directly used for diagnosing the heart health condition.
Particularly, with the wide application of electronic technology in the medical field, a user can monitor body parameters including heart rate, respiration, blood oxygen and the like by wearing related electronic equipment, draw a pattern or a chart to the user, and even perform exception prompt so as to facilitate the user to find out exception and seek medical advice in time. The electrocardiogram can be used for guiding the health condition of the heart, consumer electronic equipment used by a user daily cannot draw the electrocardiogram, the user needs to go to a hospital or use professional medical equipment to perform electrocardiogram diagnosis, the convenience is not high, and equipment capable of drawing images does not have the unified standard, so that drawn patterns do not have medical clinical reference significance.
In this embodiment, the monitoring device communicates with the mobile terminal through bluetooth connection, and the mobile terminal can receive monitoring data for heartbeat sent by the monitoring device in real time. In the aspect of Bluetooth communication, a Bluetooth software development kit or a tool library of a third-party supplier is not used, and the mobile terminal directly interacts with the monitoring equipment to process data. Therefore, the accuracy of the received data and the real-time performance of data receiving can be ensured, the monitoring data packet loss can not be caused, and the real condition of the heart rate can be reflected. The received data is processed by filtering, packet sticking and the like to obtain level data for drawing patterns. It will be appreciated that raw monitoring data is typically some digital code and is not user readable, whereas processed data is rendered medically meaningful so that medical diagnosis can be made through the rendered pattern.
The predetermined rule refers to a drawing rule of an electrocardiogram conforming to medical significance, and includes, for example, how to set an electrocardiogram drawing and how to draw an electrocardiogram on the drawing using level data.
Bezier curves are widely used in industrial drawing operations. In the embodiment, the current heart rate condition can be accurately drawn by using the Bezier curve.
Referring to fig. 3, in some embodiments, S20 includes:
s21: and carrying out filtering processing and/or packet sticking processing on the monitoring data to obtain level data.
In some embodiments, S21 may be implemented by processing module 114. That is, the processing module 114 is configured to perform filtering processing and/or packet sticking processing on the monitoring data to obtain the level data.
In some embodiments, the processor is configured to filter and/or glue the monitoring data to obtain the level data.
Specifically, the monitoring data transmitted by the monitoring device is 16-system number, which has no medical significance, and the clinical electrocardiogram records the curve of voltage change along with time. Therefore, the monitoring data needs to be processed, so that the monitoring data can become data which can be mapped and has medical significance after being processed.
In the processing process, the received monitoring data passes through a filter function, dirty data without practical significance are filtered, and then millivolt level data can be obtained. Meanwhile, due to the fact that the monitoring device and the mobile terminal are in high-speed communication, the problem of monitoring data packet sticking may exist, and therefore data packet sticking processing is needed for the problem of data packet sticking which may occur. For example, a complete set of messages consisting of aa beginning and 5a ending with other data in between: aa 00010203045 a, however, during the communication, the mobile terminal may not receive a complete one, such as 1 half message: aa 00010203045 a aa 0102, in which case the message needs to be processed into a complete message information, that is: aa 00010203045 a.
Therefore, the accuracy of the monitoring data can be ensured, and the phenomenon of packet loss can not occur.
Referring to fig. 4, in some embodiments, S30 includes:
s31: the background plot is drawn at a set size.
In some embodiments, S31 may be implemented by the drawing module 116, that is, the drawing module 116 is configured to draw the background map with a set size.
In some embodiments, the processor is configured to render the background map at a set size.
Referring to fig. 5, specifically, in clinical practice, an electrocardiogram is recorded on a graph paper composed of small lattices of 1mm in width and 1mm in height. The abscissa represents time and the ordinate represents voltage. Recording is usually carried out at a paper speed of 25mm/s, 1 ═ 1mm ═ 0.04 seconds. The ordinate voltage 1, small grid 1mm 0.1 mv.
Therefore, in order to make the pattern drawn by the mobile terminal clinically meaningful, it is necessary to draw a background map in accordance with the specification of the coordinate values of the medical electrocardiogram.
In this embodiment, the background map includes a plurality of 5 mm-long square grids, and each square grid includes 5 sub-grids, that is, each sub-grid is a 1mm × 1mm square grid. The monitoring device transmits monitoring data at a frequency of 250 counts/second, i.e. a recording speed of 25 mm/s. 50 monitor data are plotted in each square, and 10 monitor data are plotted in each sub-grid. The height of each millivolt level data corresponds to the side length of 2 square grids, namely, the vertical coordinate direction is 1mv to 10mm, and each small grid is 1mm to 0.1 mv.
In this way, the background map is drawn according to the electrocardiogram coordinate paper used clinically, so that both the background map and the level data drawn thereon have medical significance.
Referring to fig. 6, in some embodiments, S30 includes:
s32: determining the corresponding relation between the sub lattices and the display device pixel points according to the resolution of the display device of the mobile terminal;
s33: an electrocardiogram is drawn on the background map in accordance with a predetermined rule system and the level data.

In some embodiments, the processor is configured to determine correspondence between the sub-lattices and the pixel points of the display device according to a resolution of the display device of the mobile terminal, and to render an electrocardiogram on the background map according to a predetermined rule system and the level data.
Specifically, for mobile terminal products of different models, resolutions of display devices are generally different, and in order to make electrocardiograms drawn by mobile terminals of different resolution have a unified medical meaning, in this embodiment, a 1mm engineering quantity is converted into the number of pixels of a current display device, that is, the length of 1mm that how many pixels of the current display device can display is determined, and coordinate points of the current display device are respectively recorded and drawn.
In one example, the length of the sub-grid and the pixels may be converted by the following method, the width of the display area of the display device and the number of pixels in the width direction are respectively obtained, and the ratio of the two is further calculated, so as to obtain how many pixels correspond to 1 mm. In this manner, according to the conversion ratio, the drawing of the level data can be performed at the corresponding pixel point. And although the drawing proportion of the mobile terminals with different resolutions is different, the mobile terminals with different resolutions have the same engineering quantity and the same medical reference meaning.
Referring to fig. 7, in some embodiments, S30 includes:
s34: drawing by taking 50 level data as a group;
s35: drawing a set of level data patterns in a square grid at a time;
s36: the patterns are drawn on the display device in order from left to right to obtain an electrocardiogram.
In some embodiments, S34-S36 may be implemented by rendering module 116. Alternatively, the drawing module 116 is used for drawing a group of 50 level data, drawing a group of level data patterns in a square at a time, and drawing the patterns sequentially from left to right on the display device to obtain an electrocardiogram.
In some embodiments, the processor is configured to render a set of 50 level data, and to render a pattern of the set of level data in one square at a time, and to render the pattern sequentially from left to right on the display device to obtain an electrocardiogram.
Specifically, in this embodiment, every 50 pieces of level data are grouped, and a refresh is triggered, where a section of pattern in the electrocardiogram is drawn, and 50 pieces of level data correspond to a square grid, that is, 5 sub-grids. And splicing the patterns of the square grids to obtain the electrocardiogram. Therefore, the effect of dynamically refreshing and displaying the electrocardiogram in the current screen can be realized.
Drawing from left to right is in accordance with the drawing mode of electrocardiogram in medicine and the reading habit of users and diagnosis.
Referring to fig. 8, in some embodiments, S35 further includes:
s351: setting a plurality of level data to be in a transparent state to obtain a transparent point interval;
s352: respectively drawing a first sub-pattern of a transparent point interval and a second sub-pattern outside the transparent point interval in a group of level data by taking the transparent point interval as a boundary;
s353: the first sub-pattern is displayed in a transparent state and the second sub-pattern is displayed in a solid state.
In some embodiments, S351-S353 may be implemented by the rendering module 116. Or, the drawing module 116 is configured to set a plurality of level data to be in a transparent state to obtain a transparent point interval, and to draw a first sub-pattern of the transparent point interval and a second sub-pattern outside the transparent point interval in a group of level data, respectively, with the transparent point interval as a boundary, and to display the first sub-pattern in the transparent state and the second sub-pattern in the physical state.
In some embodiments, the processor is configured to set a plurality of level data to be in a transparent state to obtain a transparent dot interval, and to draw a first sub-pattern of the transparent dot interval and a second sub-pattern outside the transparent dot interval in a set of level data, respectively, with the transparent dot interval as a boundary, and to display the first sub-pattern in the transparent state and the second sub-pattern in the physical state.
Referring to fig. 9, specifically, in the actual drawing, in order to identify the current drawing progress and enable the user to clearly determine the current drawing position, a plurality of the set of 50 level data are set to be in a transparent state to form a transparent point interval, that is, a sub-pattern drawn by the points is displayed or not displayed in a transparent state, and the user can know the square position of the current drawing.
And taking the transparent point interval as a boundary, dividing a group of level data which is refreshed currently into two parts, namely a transparent state and a non-transparent state, respectively drawing sub-patterns of the transparent state and the non-transparent state, displaying the first sub-pattern in the transparent state, and displaying the second sub-pattern in the solid state. The first sub-pattern and the second sub-pattern are spliced together to form the square electrocardiogram pattern.
The number of level data set to the transparent state may be set at the time of factory shipment, for example, to 20, that is, 20 of 50 data refreshed at a time are in the transparent state, for example, the first 20 data refreshed at a time are set to the transparent state, that is, one square grid is updated at a time, and the transparent refresh visual experience in which the first two grids are transparent by 40% is better. Of course, the number of data in the transparent state may be set to 25 or 30 in order to indicate where the refresh is to be performed, and is not limited herein as long as the user can know the refresh position.
From the electrocardiogram whole body, the transparent point interval divides the electrocardiogram into front, middle and rear three sections, and the front section is an electrocardiogram pattern drawn according to all level data before the refreshing position of the transparent interval. The middle section is a first sub-pattern drawn by level data which is set to be in a transparent state and is refreshed currently. The latter section is a second sub-pattern drawn by the level data of the non-transparent state among the 50 level data of the current refresh and a pattern existing in the previous period.
Therefore, through the setting of the transparent interval, firstly, the user can know the current drawing position, secondly, a new effect similar to dynamic refreshing can be realized, and the user experience is better.
Referring to fig. 10, in some embodiments, S36 further includes:
s361: judging whether the current group of level data drawing positions exceed the display range of the display device or not;
s362: if the drawing position is out of the display range, the level data out of the display range is drawn from the initial position of electrocardiographic drawing and covers the existing pattern.
In some embodiments, S361, S362 may be implemented by the mapping module 116. Alternatively, the drawing module 116 is configured to determine whether a current set of the drawing positions of the level data exceeds the display range of the display device, and draw the level data exceeding the display range from the initial position of the electrocardiograph drawing and cover the existing pattern if the drawing positions exceed the display range.
In some embodiments, the processor is configured to determine whether a current set of the level data rendering positions is out of a display range of the display device, and to render the level data out of the display range from an initial position of electrocardiographic rendering and to cover an existing pattern in a case where the rendering position is out of the display range.
Specifically, in this embodiment, a single-screen drawing manner is adopted instead of scrolling, that is, after the current screen has been drawn, the pattern is moved forward to leave the last position for drawing the current refreshed level data, but is redrawn from the initial position of drawing, and the previous pattern is covered. In order to enable the display device to display a plurality of complete square grids, when drawing a background picture, the display range of the electrocardiogram under the condition of single screen can be set according to the width size of the display device.
The storage of the level data of the full screen is recorded by the array. And replacing the level data at the corresponding position of the array after every 50 level data are refreshed and updating the pattern. The position of the current refresh is recorded by the index, which is incremented by 50 after each refresh. When the index is out of the display range, the index is re-recorded from 0. Therefore, the effects of not rolling a single electrocardiogram screen and dynamically refreshing new electric waves are realized.
It should be noted that, although the following pattern may cover the preceding pattern during the process of drawing the electrocardiogram due to the limitation of the display range, the recording of the level data is not covered, but the level data refreshed each time is stored in sequence, and all the information monitored when the heart rate is monitored may be stored in a local storage space. After diagnosis, the current monitoring data can be uploaded to the cloud and recorded according to time for later reference.
It can be understood that the data of each heart rate monitoring can not be completely drawn in one screen, and the stored data is more comprehensive and complete, so that more comprehensive diagnosis can be performed. And the stored historical data can be used for tracking the health condition for a period of time.
