[0024] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0025] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0026] Figure 1 This is a flowchart illustrating a method for placing chest leads according to an embodiment of the present invention. The method can be performed by a chest lead placement device, which can be implemented in hardware and / or software. Figure 1 As shown, the method includes:

[0027] like Figure 1 As shown, the method in this embodiment may specifically include:

[0028] S110: Acquire first pressure data collected by at least two first pressure sensors.

[0029] The first pressure sensor is disposed on the surface of the examination bed, and the first pressure data is used to represent the pressure level between the target user and the examination bed. The first pressure sensors can be arranged in a matrix on the surface of the examination bed to synchronously collect the first pressure data between the target user and the examination bed at high frequency; alternatively, they can be arranged in a circular, triangular, or any irregular shape. During arrangement, the first pressure sensors can be arranged at equal intervals or at random intervals; for example, for the chest and abdomen positions on the examination bed, the distance between the first pressure sensors is smaller to more accurately determine the pressure at various locations on the target user's chest and abdomen.

[0030] Furthermore, when two or more first pressure sensors are set, different sensor identifiers can be set for different first pressure sensors. While acquiring the first pressure data collected by the first pressure sensor, the sensor identifier of the first sensor that collected the first pressure data is identified, facilitating differentiation during subsequent data processing.

[0031] S120. Based on the first pressure data, construct a three-dimensional image model corresponding to the target user.

[0032] The three-dimensional image model is an image model that contains the correspondence between the respiratory cycle phases of the target user and the shape of the chest and abdomen contour.

[0033] It should be noted that respiration refers to the process of gas exchange between the body and the external environment. Respiratory movements are divided into thoracic breathing and abdominal breathing. Thoracic breathing mainly involves the movement of the intercostal muscles, with relatively weak diaphragmatic activity, and is a type of breathing movement in which the rib cage expands significantly during respiration. In abdominal breathing, the diaphragm descends during inhalation, pushing the organs downwards, thus causing the abdomen to expand.

[0034] As can be seen, the contour shape of the target user's chest and abdomen varies depending on the respiratory state of the target user. For example, the contour expands when the target user inhales and shrinks when the target user exhales. When the contour expands, the initial pressure data between the target user and the examination bed increases accordingly; when the contour shrinks, the initial pressure data between the target user and the examination bed decreases accordingly. Therefore, the shape of the target user's chest and abdomen can be reflected through the initial pressure data, thus constructing a three-dimensional image model of the target user.

[0035] In specific implementation, based on the first pressure data, a three-dimensional image model corresponding to the target user is constructed, including: determining the pressure distribution corresponding to the target user based on the first pressure data collected at each time; determining the target pressure data corresponding to the target area of ​​the target user based on the pressure distribution corresponding to each collection time and the placement position of each first pressure sensor; establishing a pressure distribution image model based on the target pressure data; and constructing the three-dimensional image model based on virtual human technology and the pressure distribution image model.

[0036] The pressure distribution image module is a model that includes the correspondence between the respiratory cycle phases of the target user and the first pressure data.

[0037] Specifically, based on the first pressure data collected at each time point from the first pressure sensor, the pressure conditions at different locations of the target user can be determined to form a pressure distribution pattern. The target pressure data corresponding to the first pressure sensor placed in the target area is determined, and a pressure distribution image model is established based on each target pressure data point.

[0038] Optionally, the target pressure data corresponding to the target area of ​​the target user is determined, including: determining the lumbar pressure data corresponding to the lumbar region of the target user; wherein, the lumbar region is the area below the lower edge of the twelfth rib and above the upper edge of the iliac crest of the target user.

[0039] Specifically, breathing causes changes in the shape of the target user's chest and abdomen. Since the target user lies flat on the examination bed during ECG testing, the chest and abdomen do not directly contact the bed. Therefore, the target area can be set as the lumbar region, and the changes in the shape of the chest and abdomen can be reflected by the lumbar pressure data corresponding to the lumbar region.

[0040] In this embodiment, a pressure distribution image model is established based on the target pressure data, including: determining the respiratory cycle phase corresponding to each acquisition time for the target pressure data at each acquisition time, so as to establish a mapping relationship between the respiratory cycle phase and the target pressure data; and establishing a pressure distribution image model based on the mapping relationship and the first pressure data.

[0041] The respiratory cycle phase includes the expiratory phase and the inspiratory phase. Those skilled in the art will know that the respiratory cycle phase corresponding to each acquisition time can be determined by comparing the magnitudes of target pressure data at adjacent acquisition times.

[0042] Based on the determined respiratory cycle phases corresponding to each acquisition time, a mapping relationship between the respiratory cycle phases and the target pressure data can be established. Based on the mapping relationship and each first pressure data, a pressure distribution image model can be established.

[0043] In practice, the respiratory cycle phase corresponding to each acquisition time is determined as follows: if the target pressure data at the current acquisition time is greater than the target pressure data at the previous acquisition time, then the current acquisition time is determined to be the inspiratory phase of the expiratory cycle; if the target pressure data at the current acquisition time is less than the target pressure data at the previous acquisition time, then the current acquisition time is determined to be the expiratory phase of the expiratory cycle.

[0044] Furthermore, when there are two or more first pressure sensors, the respiratory cycle phase corresponding to each acquisition time can be determined by comparing the sum of the target pressure data at two adjacent acquisition times and the average value between the target pressure data.

[0045] For example, the area below the lower edge of the twelfth rib and above the upper edge of the iliac crest is defined as the lumbar region. The sum of lumbar pressure data collected by each first pressure sensor corresponding to the lumbar region is calculated. The sum of lumbar pressure data at adjacent collection times is compared. If the sum of lumbar pressure data at the current collection time is greater than the sum of lumbar pressure data at the previous collection time, then the current collection time is the inspiratory phase; conversely, if the sum of lumbar pressure data at the current collection time is less than the sum of lumbar pressure data at the previous collection time, then the current collection time is the expiratory phase.

[0046] By determining the respiratory cycle phase corresponding to each acquisition time, a mapping relationship between the respiratory cycle phase and the target pressure data is established; based on the mapping relationship and the first pressure data, a pressure distribution image model is established.

[0047] As those skilled in the art will understand, virtual human technology refers to a three-dimensional model synthesized by simulating real human organs using digital technology. A virtual human not only possesses the physical appearance of a human body and the features of organs such as the liver, heart, and kidneys, but also exhibits the metabolic functions of these organs, realistically displaying the normal physiological state and various changes that occur in the human body. In this embodiment, based on virtual human technology and first pressure data, the chest and abdominal contour shape of the target user can be constructed; based on the pressure distribution image model, establishing the correspondence between the respiratory cycle phases and the chest and abdominal contour shape allows for the construction of a three-dimensional image model.

[0048] S130. Based on the three-dimensional image model, determine the current placement coordinates of the chest leads on the target user's chest and abdomen, and control the placement of each chest lead according to the current placement coordinates.

[0049] In this embodiment, the method for determining the current placement coordinates of the chest leads on the chest and abdomen of the target user based on the three-dimensional image model can be as follows: based on the three-dimensional image model, determine the coordinate path of each chest lead corresponding to the respiratory cycle; based on the coordinate path, determine the current placement coordinates of the chest leads on the chest and abdomen of the target user, and control the placement of each chest lead according to the current placement coordinates.

[0050] The coordinate path is a path composed of the placement coordinates of the chest leads corresponding to each breathing phase, where the placement coordinates are the coordinate positions of the chest leads on the chest and abdominal contour.

[0051] In practice, the method for determining the coordinate paths of each chest lead corresponding to the respiratory cycle can be as follows: Based on the three-dimensional image model, determine the stable chest and abdominal contour shape of the target user and the corresponding stable respiratory phase in a stable state; based on the chest lead placement requirements and the stable chest and abdominal contour shape, determine the stable placement coordinates of each chest lead in a stable state; based on the correspondence between the stable placement coordinates and the stable respiratory phase, determine the coordinate path.

[0052] The stable state can be the state in which the target user's chest and abdominal contour shape remains stable; optionally, the stable state can be the state when the inspiratory volume is 1 / 2 tidal volume, which can determine the stable chest and abdominal contour shape and stable breathing phase corresponding to the target user's inspiratory volume of 1 / 2 tidal volume.

[0053] It should be noted that at the end of inhalation, the sum of the volumes of the thoracic cavity and the abdomen is at its maximum. Based on the three-dimensional image model, the shape of the thoracic and abdominal contours at the end of inhalation can be determined. At the end of exhalation, the sum of the volumes of the thoracic cavity and the abdomen is at its minimum. Based on the three-dimensional image model, the shape of the thoracic and abdominal contours at the end of exhalation can be determined.

[0054] Those skilled in the art will know that tidal volume can be set as: (chest volume at the end of inspiration + abdominal volume at the end of inspiration) - (chest volume at the end of expiration + abdominal volume at the end of expiration). It should be noted that the degree of volume change in lung tissue and intra-abdominal tissue differs under the same pressure change. Inspiratory volume can be set as: (chest volume + abdominal volume) - (chest volume at the end of expiration + abdominal volume at the end of expiration). Therefore, the respiratory phase can be determined when the inspiratory volume is 1 / 2 tidal volume. When the steady state is when the inspiratory volume is 1 / 2 tidal volume, the corresponding respiratory phase is the stable respiratory phase, and based on a three-dimensional image model, the stable chest and abdominal contour shape corresponding to stable breathing is determined.

[0055] Furthermore, before determining the stable placement coordinates of each chest lead in a stable state, the placement requirements for the chest leads need to be determined. For example, there can be six chest leads, labeled with red, yellow, green, brown, black, and purple, and numbered V1, V2, V3, V4, V5, and V6 respectively. The placement requirements for the chest leads can be as follows: V1 lead - right sternal border, 4th intercostal space; V2 lead - left sternal border, 4th intercostal space; V3 lead - midpoint of the line connecting V2 and V4; V4 lead - left midclavicular line, 5th intercostal space; V5 lead - left anterior axillary line, at the same level as V4; V6 lead - midaxillary line, at the same level as V4.

[0056] Specifically, based on the placement requirements of the chest leads and the stable shape of the chest and abdomen, the stable placement coordinates of each chest lead in a stable state can be determined. The correspondence between the stable placement coordinates and the stable respiratory phase is used as a reference standard to determine the coordinate path. For example, based on the three-dimensional image model, the correspondence between the stable placement coordinates and the stable respiratory phase, the three-dimensional coordinates of the contact points between each chest lead and the thoracic cage in each respiratory phase are determined, and the three-dimensional coordinates of the contact points between each chest lead and the thoracic cage during deep inspiration and deep expiration are calculated. For each chest lead, the three-dimensional coordinates of the contact points between the chest leads and the thoracic cage in each respiratory phase are connected to form the respiratory cycle phase-chest lead path, i.e., the coordinate path.

[0057] In this embodiment, the specific implementation of determining the current placement coordinates of the chest leads on the chest and abdomen of the target user based on the coordinate path can be as follows: the respiratory phase of the target user's respiratory cycle corresponding to the current moment can be determined; and the placement coordinates corresponding to the respiratory phase can be determined based on the coordinate path, and the placement coordinates can be determined as the current placement coordinates corresponding to the current moment, so that the placement of each chest lead can be controlled according to the current placement coordinates.

[0058] The technical solution of this invention involves acquiring first pressure data collected by at least two first pressure sensors, wherein the first pressure sensors are disposed on the surface of the examination bed, and the first pressure data is used to represent the pressure level between the target user and the examination bed; constructing a three-dimensional image model corresponding to the target user based on the first pressure data; wherein the three-dimensional image model is an image model containing the correspondence between the respiratory cycle phases of the target user and the chest and abdominal contour shapes; determining the current placement coordinates of the chest leads on the target user's chest and abdomen based on the three-dimensional image model, thereby taking into account the corresponding chest and abdominal contour shapes during each breath of the target user's respiratory cycle, determining the current placement coordinates, and controlling the placement of each chest lead according to the current placement coordinates. This solves the problems of chest lead position adjustment and excessively high or low pressure applied to the target user during ECG testing in the prior art, and achieves the effects of improving the accuracy of chest lead placement, ECG signal acquisition quality, and user comfort during ECG examination.

[0059] In this embodiment, after controlling the placement of each chest lead according to the current placement coordinates, the method further includes: acquiring second pressure data collected by the second pressure sensor corresponding to the current placement coordinates of each chest lead; wherein the second pressure sensor is set between the robotic arm and the chest lead; based on the second pressure data, determining the target placement coordinates of each chest lead, and controlling the movement of the robotic arm to drive each chest lead to be placed according to the target placement coordinates.

[0060] Specifically, the second pressure sensor is positioned between the robotic arm and the chest leads, enabling high-frequency acquisition of second pressure data between them. Since both the robotic arm and the chest leads are made of inelastic materials, the second pressure data between the chest leads and the robotic arm represents the second pressure data between the chest leads and the target user's current placement coordinates on the chest and abdomen. The second pressure data corresponding to the current placement coordinates of the chest leads, collected by the pressure sensor at each respiratory phase, can be acquired to understand the force exerted on the target user during ECG monitoring.

[0061] In practical implementation, the target placement coordinates can be determined based on the negative feedback control principle and the second pressure data. Optionally, if the second pressure data exceeds a preset pressure range, the excess value corresponding to the second pressure data and the magnitude relationship between the second pressure data and the pressure range are determined; based on the excess value, the magnitude relationship, and the current placement coordinates, the target placement coordinates of each chest lead are determined.

[0062] The preset pressure range can be a range of pressure values ​​that ensures the accuracy of ECG data while preventing the target user from feeling pressure. Those skilled in the art can set the pressure range according to actual application conditions; this embodiment does not limit this.

[0063] This invention uses a second pressure sensor positioned between the robotic arm and the chest leads to determine the pressure experienced by the target user during ECG detection. Based on the principle of negative feedback, the pressure data is used to determine the target placement coordinates of the chest leads. This ensures that the pressure data experienced by the target user is within a reasonable range after the chest leads are placed according to the target coordinates, and prevents them from falling off, thus enabling accurate detection of the target user's ECG data.
