Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a recording device, equipment and storage medium based on a cardiopulmonary resuscitation feedback device. Background Technology

[0002] Cardiac arrest is a near-death state caused by the sudden cessation of the heart's pumping function due to arrhythmia and / or the disappearance of effective cardiac contractions, resulting in interruption of systemic blood circulation, respiratory arrest, and loss of consciousness. Cardiopulmonary resuscitation (CPR) is the cornerstone of saving the lives of cardiac arrest patients. For most of the time after cardiac arrest, effective chest compressions must generate sufficient blood flow to deliver oxygen and metabolic substrates to critical organs and tissues; the restoration of spontaneous circulation depends on the oxygen and blood flow delivered to the myocardium during CPR.

[0003] Clinical big data has confirmed that high-quality chest compressions are essential for improving the resuscitation success rate of cardiac arrest patients. Therefore, current international guidelines require strict control of chest compression quality and specify concrete indicators for various quality parameters. However, studies have shown that manual compressions rarely meet the guidelines, even for trained personnel, because rescuer fatigue can negatively impact compression quality.

[0004] Therefore, existing technologies include chest compression feedback devices that can collect, analyze, and provide feedback on data during manual compressions, thus providing a basis for the evaluation and guidance of chest compressions. However, the data collected and analyzed by existing chest compression feedback devices is not comprehensive enough, lacking both guidance for ordinary users and detailed data for professionals.

[0058] Exemplary embodiments of the present application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be implemented in various forms and should not be limited to the specific embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present application and to fully convey the scope of the disclosure of the present application to those skilled in the art.

[0059] The following description provides numerous specific details to offer a more thorough understanding of this application. However, it will be apparent to those skilled in the art that this application can be practiced without one or more of these details. In other instances, to avoid confusion with this application, some technical features well-known in the art have not been described; that is, not all features of actual embodiments are described herein, nor are well-known functions and structures described in detail.

[0060] To fully understand this application, detailed steps and structures will be presented in the following description to illustrate the technical solution of this application. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other implementation methods.

[0061] To address the technical problems in related technologies, this application provides a recording device based on a cardiopulmonary resuscitation (CPR) feedback device. The recording device can be located within the CPR feedback device, and the structure of the CPR feedback device can be referenced. Figure 1 The usage scenarios for this cardiopulmonary resuscitation feedback device can be referenced. Figure 2 and Figure 3 . refer to Figure 1 The cardiopulmonary resuscitation feedback device 100 may include: a housing 110, a pressure sensor 120, and an acceleration sensor 130.

[0062] like Figure 2 and Figure 3As shown, the person to be rescued should lie supine on a flat surface or have a chest compression board placed under their shoulders and back. The rescuer can use different positions, such as kneeling, to position themselves to one side of the person. The rescuer should place the CPR feedback device 100 above the person's chest and place their hands on the device to begin hands-only CPR. The rescuer should strive to maintain continuous and effective chest compressions, which should be rapid, forceful, and uninterrupted.

[0063] In this application, "the person to be rescued" refers to anyone who may require emergency care due to conditions such as cardiac arrest, respiratory distress, traumatic injury, shock, or other conditions that may require resuscitation; "rescue personnel" refers to caregivers or rescuers who perform manual chest compressions, and is also at least one of the users of the cardiopulmonary resuscitation feedback device 100, and generally directly uses the cardiopulmonary resuscitation feedback device 100; however, users may include not only rescue personnel, but also other persons who indirectly use the cardiopulmonary resuscitation feedback device 100, such as other persons who view the quality parameters fed back by the cardiopulmonary resuscitation feedback device 100.

[0064] like Figure 4 As shown, the recording device 400 based on the cardiopulmonary resuscitation feedback device (hereinafter referred to as the recording device) includes an acquisition module 401, an identification module 402, and a recording module 403, wherein:

[0065] The acquisition module 401 is used to acquire the cardiopulmonary resuscitation situation of the organism and the electrocardiogram signal of the organism.

[0066] For example, the cardiopulmonary resuscitation (CPR) situation of the organism can include whether the organism is performing CPR measures such as chest compressions and lung ventilation. For example, the organism can be a human or other organisms with similar patterns to humans. The electrocardiogram (ECG) signal can be the bioelectrical signal generated by the heart in each cardiac cycle. The preset time can be the duration of multiple cardiac cycles, such as 5-10 cardiac cycles, approximately 4-8 seconds. It is understood that the preset time can also be set longer or shorter as needed. For better observation, the ECG signal can be recorded in a common electrocardiogram (ECG) format, that is, the ECG signal is displayed through waveform changes.

[0067] The identification module 402 is used to identify whether the organism is in a state of being defibrillated based on the acquired electrocardiogram signal.

[0068] For example, when the organism is in a state of being defibrillated, since defibrillation is an external high-value electrical signal, the organism's electrocardiogram signal will be significantly affected, and its electrocardiogram signal will be different from other situations.

[0069] In some embodiments, the identification module 402 is specifically used for:

[0070] Obtain the signal value from the electrocardiogram signal of the organism;

[0071] When the signal value is greater than a preset value, it is determined that the organism is in a state of being defibrillated and feedback is provided.

[0072] For example, generally, because the electrical signal value of defibrillation discharge is very high, it can cause the electrocardiogram (ECG) signal of a living organism to increase accordingly, far exceeding the normal ECG signal value. Therefore, the highest value of the ECG signal can be used to identify whether the living organism is in a defibrillation state. In some other embodiments, the rate of change of the ECG signal can also be used to determine whether the living organism is in a defibrillation state. The ECG used to determine whether the living organism is in a defibrillation state can be as follows: Figure 5 As shown.

[0073] The recording module 403 is used to record the cardiopulmonary resuscitation and defibrillation of the organism.

[0074] For example, when performing defibrillation on a living organism, there is the issue of evaluating its effectiveness, specifically the organism's recovery after defibrillation. Therefore, it is necessary to record the defibrillation process of the organism using the recording module 403. This allows for subsequent big data analysis to assess the quality of the defibrillation procedure and its corresponding effects. Furthermore, since the effectiveness of defibrillation may be related to the procedures performed before defibrillation, it is also necessary to record the details of cardiopulmonary resuscitation (CPR) for combined analysis.

[0075] In some embodiments, the recording module 403 is further configured to:

[0076] If the organism is determined to be in a state of being defibrillated, the time point of the defibrillation discharge and the rescue status before the time point of the defibrillation discharge are recorded.

[0077] For example, there is also a timing issue when performing defibrillation on a living organism, namely, whether defibrillation is performed at an appropriate time. Furthermore, the recovery status of the organism after defibrillation, i.e., the effectiveness, can be correlated with the timing through post-event analysis. For instance, a large amount of data on defibrillation performed on organisms can be collected, including data on other cardiopulmonary resuscitation (CPR) procedures. In this way, big data analysis can be used to determine the correlation between the effectiveness of defibrillation and the timing. Therefore, the recording module 403 records the CPR procedures and defibrillation procedures performed on the organism.

[0078] In some embodiments, the identification module 402 is further configured to:

[0079] Based on the signal data obtained from the measuring component used to acquire the electrocardiogram signal of the organism, the location information of the measuring component is determined and fed back; the location information includes whether the measuring component is on the organism or not.

[0080] For example, the signal data can be an electrocardiogram (ECG) signal, other signals, or even an empty signal. For instance, if the measuring component is placed on a living organism, the signal data can be an ECG signal or body temperature, signals unique to living organisms; otherwise, it may be other signals or an empty signal. Therefore, the identification module 402 can determine whether the measuring component is located on a living organism based on the signal data, thus identifying whether the measuring component is located on or detached from the living organism.

[0081] In some embodiments, the recording module 403 is further configured to:

[0082] The pressure changes and undulations of the thoracic cavity applied to the organism are obtained; the undulations include the bulging and contraction of the thoracic cavity.

[0083] Based on the pressure changes and fluctuations, the cardiopulmonary resuscitation (CPR) status of the organism is determined, recorded, and reported; the CPR status includes chest compression status and lung ventilation status.

[0084] For example, it can be determined whether chest compressions should be performed based on changes in pressure applied to the chest cavity of the organism, and / or based on the rise and fall of the chest cavity of the organism. That is, in general, it is possible to determine whether chest compressions should be performed based solely on changes in pressure or solely on the rise and fall of the chest cavity; combining both can lead to a more accurate determination.

[0085] For example, whether pulmonary ventilation is being performed can be determined based on the rise and fall of the chest cavity on the organism and the pressure changes applied to the chest cavity on the organism. Generally, pulmonary ventilation cannot be performed during chest compressions. Therefore, determining pulmonary ventilation can also combine both the pressure changes and the rise and fall of the chest cavity. For example, a pressure applied to the chest cavity on the organism that is less than a preset value can be used as a necessary condition for confirming pulmonary ventilation. Due to errors or zero-point drift in the pressure sensor 120, the preset value can be a value close to zero, but it is generally set to be greater than zero. For example, after determining the cardiopulmonary resuscitation status of the organism, the status can be recorded and fed back, using the same methods as above, such as indicator lights, speakers, etc. In some embodiments, the recording module 403 acquires the pressure changes applied to the chest cavity on the organism via the pressure sensor 120. The rise and fall of the chest cavity on the organism can be acquired via the accelerometer 130.

[0086] In some embodiments, the recording module 403 is further configured to:

[0087] If the cardiopulmonary resuscitation (CPR) procedure is chest compressions...

[0088] Based on the pressure changes, determine the number of chest compressions to be performed, and record and report the results.

[0089] For example, the number of chest compressions is a key indicator in cardiopulmonary resuscitation (CPR). Typically, chest compressions are performed in a 30:2 ratio, meaning 30 compressions followed by approximately 2 pauses before resuming. Therefore, the recording module 403 needs to record and report the number of chest compressions. For example, during chest compressions, the pressure applied to the chest cavity undergoes a cyclical process of increasing and decreasing, which is definite in relation to the number of compressions. Thus, the recording module 403 can determine the number of chest compressions by observing the changes in chest pressure applied to the body. For example, during chest compressions, the chest cavity deforms due to the applied pressure, and the degree of deformation also undergoes a cyclical process of increasing and decreasing, which is also definite in relation to the number of compressions. Therefore, the recording module 403 can also determine the number of chest compressions by observing the deformation of the chest cavity caused by the applied pressure. For example, the results of both methods can be combined to determine the number of chest compressions, thus providing a more accurate determination of the number of compressions. For example, the deformation of the pleural cavity in the organism can be detected using an accelerometer 130.

[0090] In some embodiments, the recording module 403 is further configured to:

[0091] If the cardiopulmonary resuscitation (CPR) is performed while the lungs are ventilated,

[0092] The timing of lung ventilation is determined, recorded, and reported based on the time of chest cavity bulging and / or chest cavity contraction; the timing includes correct timing and incorrect timing.

[0093] For example, the lung ventilation status data may include the timing of lung ventilation and the quality data of lung ventilation. The lung ventilation status data can be determined by the recording module 403 through the rise and fall of the chest cavity on the organism. For example, after determining that lung ventilation has occurred through the rise and fall and the changes in biological pressure, the lung ventilation status data, i.e., the timing and quality of lung ventilation, can be determined based on the rise and fall of the chest cavity on the organism.

[0094] For example, in cardiopulmonary resuscitation (CPR), ventilation typically begins when chest compressions cease. Therefore, the recording module 403 needs to determine the timing of ventilation to instruct the device's operation and provide feedback to the user. For example, determining the timing of ventilation generally requires only one point in time of chest cavity rise or one point in time of chest cavity contraction. Alternatively, it can combine one point in time of chest cavity rise and one point in time of chest cavity contraction, or multiple points in time of chest cavity rise and multiple points in time of chest cavity contraction. In some embodiments, the chest cavity rise and contraction can be converted into a waveform graph. Specifically, the waveform graph can be plotted with time on the horizontal axis and the height of chest cavity rise on the vertical axis. Figure 6 The waveform representing chest cavity fluctuations acquired by the recording device based on a cardiopulmonary resuscitation feedback device provided in the embodiments of this application is shown in the figure. Figure 6 The waveform illustrates a bulging process and a contraction process. The bulging waveform is an upward-convex shape, referred to as "upward convexity," and the contraction waveform is a downward-concave shape, referred to as "downward concavity." For example, the multiple points of upward convexity or downward concavity in the waveform can be obtained by transforming data detected by the accelerometer. For example, the transformation can be magnification or reduction, or other forms of transformation, the main purpose of which is to make the waveform clearer and more intuitive. That is, the waveform is a curve of acceleration change measured by the accelerometer 130; upward convexity in the waveform represents chest cavity bulging, and downward concavity represents chest cavity contraction.

[0095] In some embodiments, the recording module 403 is further configured to:

[0096] The time interval between the rise and fall of the pleural cavity is obtained, and the duration of a single ventilation of the lungs is determined.

[0097] For example, the time interval between the bulging and contraction of the pleural cavity can be obtained based on a waveform diagram, such as the distance on the horizontal axis between the starting point of the upward bulge and the ending point of the downward bulge on the waveform diagram, which can be the duration of a single ventilation of the lungs.

[0098] The volume changes of the pleural cavity corresponding to the bulging and contraction of the pleural cavity are obtained, and the ventilation rate of the lung ventilation is determined.

[0099] For example, the changes in thoracic cavity volume corresponding to the bulging and contraction of the thoracic cavity can also be obtained based on a waveform diagram. For instance, the area enclosed by the upwardly convex and downwardly concave curves on the waveform diagram can be converted into ventilation volume. For example, the area can be calculated by integration.

[0100] The number of times the chest cavity bulged and contracted was measured to determine the number of ventilations in the lungs.

[0101] For example, the number of times the chest cavity bulges and contracts can also be obtained based on the waveform diagram. For example, one upward bulge and one downward bulge can be considered one ventilation.

[0102] The quality data of lung ventilation are determined, recorded, and fed back based on the duration of each ventilation, the ventilation volume, and the number of ventilations.

[0103] For example, the quality of pulmonary ventilation can be determined by combining the duration of each ventilation cycle, the ventilation volume, and the number of ventilations. The duration of each ventilation cycle and the ventilation volume both have preset ranges; too high or too low a range indicates poor pulmonary ventilation quality. The number of ventilations needs to be judged comprehensively based on the chest compressions. For example, chest compressions and pulmonary ventilation are generally performed in a 30:2 ratio, i.e., 30 compressions followed by 2 ventilations. However, in some cases, continuous chest compressions are required without pulmonary ventilation; in such cases, a lower number of ventilations does not necessarily indicate poor pulmonary ventilation quality.

[0104] Furthermore, determining the quality of the lung ventilation may also include:

[0105] The time elapsed between the first pleural bulge and the last pleural sag during pulmonary ventilation is recorded as the cumulative pulmonary ventilation time.

[0106] Based on the cumulative time of lung ventilation, determine the quality data of lung ventilation and record and provide feedback.

[0107] The cumulative time of pulmonary ventilation is used to determine the quality of pulmonary ventilation, and this method has a similar effect to evaluating it by the number of ventilations. In general, the cumulative time of pulmonary ventilation should not be too long.

[0108] In summary, the status data of pulmonary ventilation can include the timing of pulmonary ventilation and the quality data of pulmonary ventilation.

[0109] In some embodiments, the acquisition module is further configured to:

[0110] Based on the cardiopulmonary resuscitation (CPR) situation of the organism obtained;

[0111] Determine whether to acquire the electrocardiogram signal of the organism.

[0112] Generally, defibrillation is not performed during chest compressions. Therefore, based on the cardiopulmonary resuscitation (CPR) data, it can be determined whether to obtain the patient's electrocardiogram (ECG) signal to assess whether defibrillation was administered.

[0113] Specifically, the acquisition module is also used for:

[0114] If the obtained biological entity's cardiopulmonary resuscitation situation is chest compressions, and the number of compressions reaches the preset number;

[0115] Acquire the electrocardiogram signal of the organism.

[0116] For example, defibrillation is generally not performed during chest compressions on a living organism. This is because chest compressions need to be performed continuously for a preset number of times before they can be interrupted to allow for other life-saving measures. The preset number of compressions is typically 30. Therefore, performing the step of acquiring the organism's electrocardiogram signal only after the preset number of compressions has been reached helps save energy and makes the relevant information recorded by the recording module more meaningful.
