[0026] Figure 1is a flowchart of a method for determining a chest lead placement position according to an embodiment of the present application. The method can be performed by a device for determining a chest lead placement position, which can be implemented in the form of hardware and / or software.

[0027] As shown in Figure 1 , the method of the present embodiment can specifically include:

[0028] S110, acquiring vibration data collected by at least two vibration sensors.

[0029] The vibration sensors are arranged on the surface of the examination bed, and the vibration data is used to represent the displacement degree at the contact position between the target user and the vibration sensors.

[0030] For example, the vibration sensors can be arranged on the surface of the examination bed in the form of a matrix array; or arranged on the surface of the examination bed in the form of a circle, a triangle, or any irregular shape. When arranged, the vibration sensors can be arranged at equal intervals, or arranged at random intervals; for example, the distance between the vibration sensors arranged at the chest and abdominal positions corresponding to the examination bed is small, so as to more accurately determine the vibration of each position of the chest and abdomen of the target user. By acquiring the identification information of the vibration sensors and the collected vibration data, the vibration data of each vibration sensor is determined.

[0031] In the present embodiment, after acquiring the vibration data collected by the at least two vibration sensors, the method further includes: for the vibration data collected by each vibration sensor, determining whether the vibration data exceeds a preset vibration data range; if it exceeds, controlling the vibration sensor to re-collect the vibration data, and updating the acquired vibration data.

[0032] Specifically, in order to ensure that the acquired vibration data is valid data, the preset vibration data range can be determined in advance. Those skilled in the art can determine the specific value of the preset vibration data range according to the actual application. When the determined vibration data exceeds the preset vibration data range, it indicates that the currently collected vibration data is incorrect. In order to ensure the correctness of the subsequent determination of the chest lead placement position, the vibration data needs to be deleted for re-collection, and the original vibration data is updated based on the re-acquired vibration data; when the determined vibration data does not exceed the preset vibration data range, it indicates that the currently collected vibration data is normal and can be used in the subsequent process of determining the chest lead placement position. By determining whether the vibration data exceeds the preset vibration data range, the effectiveness and correctness of the collected vibration data are ensured.

[0033] S120, constructing a target vibration model corresponding to the target user based on the vibration data corresponding to each collection time.

[0034] The target vibration model is used to reflect a first mapping relationship between a breathing cycle phase of the target user and vibration information.

[0035] It should be noted that the collected vibration data has different characteristics according to different transmission media of the vibration, different breathing phases of the target user, different airway diameters, and different airflow speeds. Therefore, according to the data characteristics of the vibration data obtained at different collection moments, the first mapping relationship between the breathing cycle phase of the target user and the vibration information can be determined, that is, the target vibration model is determined. The vibration information includes vibration frequency information and vibration intensity information, and can also include vibration amplitude information.

[0036] Optionally, based on the vibration data corresponding to each collection moment, a target vibration model corresponding to the target user is constructed, including: based on the vibration data, vibration information corresponding to each contact position is determined; for the vibration data corresponding to each collection moment, a second mapping relationship between the collection moment and the breathing cycle phase of the target user is determined; and based on the second mapping relationship and the vibration information, the target vibration model corresponding to the target user is constructed.

[0037] The breathing cycle phase includes an exhalation phase and an inhalation phase. Those skilled in the art can know that the breathing cycle phase corresponding to each collection moment can be determined by comparing the relationships of the vibration amplitudes, vibration frequencies, vibration intensities, and the like of the collected vibration data at different collection moments.

[0038] Specifically, the vibration information of each contact position can be determined according to the vibration data; for example, for the contact positions of the skeleton and the soft tissue, the vibration frequency and the vibration intensity are not the same. Moreover, based on the second mapping relationship between the different collection moments and the breathing cycle phase in which the target user is located, the first mapping relationship between the vibration information and the breathing cycle phase can be determined, so as to determine the target vibration model.

[0039] S130, based on the target vibration model, a corresponding relationship between the breathing cycle phase of the target user and the chest and abdominal contour shape is determined, and based on the corresponding relationship, a current placement coordinate of the chest lead on the chest and abdomen of the target user is determined.

[0040] It should be noted that respiration refers to the process of gas exchange between the body and the external environment. Respiratory movement is divided into chest breathing and abdominal breathing. Chest breathing is mainly based on the movement of intercostal muscles, the diaphragm is weak, and the chest is obviously expanded during breathing. When inhaling, the diaphragm will descend, pushing the organs to the lower part, so the abdomen will expand. It can be seen that with different breathing states of the target user in the breathing cycle, the contour shape of the chest and abdomen of the target user is also different. For example, when the target user inhales, the contour of the chest and abdomen expands; when the target user exhales, the contour of the chest and abdomen decreases.

[0041] Optionally, the correspondence between the respiratory cycle phase of the target user and the chest and abdominal contour shape is determined based on the target vibration model, including: determining the correspondence between the respiratory cycle phase of the target user and the chest and abdominal contour shape based on virtual human technology and the target vibration model.

[0042] As known to those skilled in the art, virtual human technology refers to a three-dimensional model synthesized by simulating real human organs through digital technology. The virtual human not only has the appearance of the human body and various organs such as liver, heart, and kidney, but also has the metabolic function of each organ, and can more realistically show the normal physiological state of the human body and various changes. In this embodiment, based on virtual human technology and vibration data at different contact positions, the chest and abdominal contour shape of the target user can be constructed; and based on the target vibration model, the correspondence between the respiratory cycle phase of the target user and the chest and abdominal contour shape is established.

[0043] In a specific implementation, the current placement coordinates of the chest leads on the chest and abdomen of the target user are determined based on the correspondence, including: determining the coordinate path of each chest lead in the respiratory cycle of the target user based on the correspondence and the chest lead placement requirement; and determining the current placement coordinates of the chest leads on the chest and abdomen of the target user at the current time based on the coordinate path.

[0044] The coordinate path is a path composed of the placement coordinates of the chest leads corresponding to each respiratory phase, and the placement coordinates are the coordinate positions of the chest leads placed on the chest and abdominal contour.

[0045] For example, the number of chest leads can be six, and the identification colors of the chest leads are red, yellow, green, brown, black, and purple, respectively, numbered as V1, V2, V3, V4, V5, and V6. The chest lead placement requirement can be: V1 lead-4th intercostal space of right sternal border; V2 lead-4th intercostal space of left sternal border; V3 lead-midpoint of the line connecting V2 and V4. V4 lead-at the intersection of the left clavicular midline and the 5th intercostal space; V5 lead-at the same horizontal position as V4 on the left anterior axillary line; and V6 lead-at the same horizontal position as V4 on the midaxillary line.

[0046] In this embodiment, based on the correspondence and the chest lead placement requirement, the placement coordinates of each chest lead on the chest and abdominal contour at each respiratory cycle phase can be determined; and based on the time sequence of the respiratory cycle phases, the contact positions can be connected into a coordinate path. In determining the current placement coordinates, the corresponding respiratory cycle phase at the current time can be determined to determine the placement coordinates of the corresponding respiratory cycle phase as the current placement coordinates.

[0047] Optionally, based on the correspondence and the chest lead placement requirement, the coordinate path of each chest lead in the respiration cycle of the target user is determined, including: based on the correspondence, a stable chest and abdomen contour shape and a corresponding stable respiration phase of the target user in a stable state are determined; based on the chest lead placement requirement and the stable chest and abdomen contour shape, stable placement coordinates of each chest lead in the stable state are determined; based on the correspondence between the stable placement coordinates and the stable respiration phase, the coordinate path is determined.

[0048] The stable state can be a state in which the chest and abdomen contour shape of the target user remains stable. Optionally, the stable state can be a state in which the inhalation volume is 1 / 2 of the tidal volume, and the stable chest and abdomen contour shape and the stable respiration phase corresponding to the state in which the inhalation volume of the target user is 1 / 2 of the tidal volume can be determined.

[0049] It should be noted that the volume sum of the thoracic volume and the abdominal volume is the largest at the end of inspiration, and the corresponding chest and abdomen contour shape can be determined according to the correspondence between the respiration phase and the chest and abdomen contour shape of the target user. The volume sum of the thoracic volume and the abdominal volume is the smallest at the end of expiration, and the corresponding chest and abdomen contour shape can be determined according to the correspondence between the respiration phase and the chest and abdomen contour shape of the target user.

[0050] As known by those skilled in the art, the tidal volume can be set as (thoracic volume at the end of inspiration + abdominal volume at the end of inspiration) - (thoracic volume at the end of expiration + abdominal volume at the end of expiration), and the inhalation volume can be set as (thoracic volume + abdominal volume) - (thoracic volume at the end of expiration + abdominal volume at the end of expiration). Thus, the respiration phase in which the inhalation volume of the human body is set to be 1 / 2 of the tidal volume can be determined. When the stable state is that the inhalation volume is 1 / 2 of the tidal volume, the corresponding respiration phase is the stable respiration phase, and the stable chest and abdomen contour shape corresponding to the stable respiration phase can be determined based on the correspondence between the respiration phase and the chest and abdomen contour shape of the target user.

[0051] Specifically, the stable placement coordinates of each chest lead in the stable state can be determined according to the chest lead placement requirement and the stable chest and abdomen contour shape. The correspondence between the stable placement coordinates and the stable respiration phase is taken as a reference standard to determine the coordinate path. For example, according to the correspondence between the respiration phase and the chest and abdomen contour shape of the target user and the correspondence between the stable placement coordinates and the stable respiration phase, the three-dimensional coordinates of the contact points between each chest lead and the thorax in each respiration phase are determined, and the three-dimensional coordinates of the contact points between each chest lead and the thorax in the case of deep inspiration and deep expiration are calculated. For each chest lead, the three-dimensional coordinates of the contact points between the chest lead and the thorax in each respiration phase are connected to form a respiration phase-chest lead path, i.e., the coordinate path.

[0052] In the embodiment, after determining the current placement coordinates of the chest leads on the chest and abdomen of the target user based on the correspondence, the method further comprises: controlling the placement of the chest leads according to the current placement coordinates; acquiring pressure data corresponding to the current placement coordinates of the chest leads collected by the pressure sensor; wherein the pressure sensor is arranged between the mechanical arm and the chest leads; determining the target placement coordinates of the chest leads based on the pressure data, and controlling the movement of the mechanical arm to drive the chest leads to be placed according to the target placement coordinates.

[0053] Specifically, the pressure sensor is arranged between the mechanical arm and the chest leads, and can collect high-frequency pressure data between the mechanical arm and the chest leads. Since the mechanical arm and the chest leads are both made of inelastic materials, the pressure data between the chest leads and the mechanical arm can be determined as the pressure data between the chest leads and the current placement coordinates of the chest and abdomen of the target user. The current placement coordinates of the chest leads corresponding to the pressure data collected by the pressure sensor at each respiratory phase can be acquired to understand the stress condition of the target user in the electrocardiogram detection.

[0054] In specific implementation, the target placement coordinates can be determined according to the negative feedback control principle and the pressure data. Optionally, if the pressure data exceeds the preset pressure range, the exceeding value corresponding to the pressure data and the size relationship between the pressure data and the pressure range are determined; and the target placement coordinates of the chest leads are determined based on the exceeding value, the size relationship and the current placement coordinates. The placement operation of the chest leads is completed by controlling the movement of the mechanical arm to drive the chest leads to be placed according to the target placement coordinates.

[0055] The preset pressure range can be a range of pressure values that can ensure the accuracy of electrocardiogram detection data and make the target user not feel squeezed. Those skilled in the art can set the pressure range according to actual application, which is not limited in the embodiment.

[0056] The technical scheme of the embodiment of the application comprises: acquiring vibration data collected by at least two vibration sensors; wherein the vibration sensors are arranged on the surface of the examination bed, and the vibration data is used to represent the displacement degree of the contact position between the target user and the vibration sensors; constructing a target vibration model corresponding to the target user based on the vibration data corresponding to each collection time; wherein the target vibration model is used to reflect the first mapping relationship between the respiratory cycle phase of the target user and the vibration information; determining the correspondence between the respiratory cycle phase of the target user and the contour shape of the chest and abdomen based on the target vibration model, and determining the current placement coordinates of the chest leads on the chest and abdomen of the target user based on the correspondence, thereby solving the problem of detection position error, and achieving the effects of improving the placement accuracy of the chest leads, the quality of electrocardiogram signal collection and the comfort of the user in the electrocardiogram examination.
