Description

Technical Field

[0001] The present application relates to the field of medical devices, and particularly to a cardiac arrest treatment device based on ultrasonic Doppler feedback technology. Background Art

[0002] Cardiac arrest refers to a life-threatening state in which the mechanical activity of the heart's pumping function suddenly stops directly due to arrhythmia and / or the disappearance of effective cardiac contractions, resulting in the interruption of systemic blood circulation, the cessation of breathing, and the loss of consciousness. Cardiopulmonary resuscitation is the cornerstone of saving the lives of patients with cardiac arrest. For most of the time of cardiac arrest, sufficient blood flow must be generated through effective external chest compressions to deliver oxygen and metabolic substrates to critical organs and tissues.

[0003] Clinical big data has confirmed that only high-quality cardiac arrest treatment measures can improve the success rate of treatment. For example, high-quality external chest compressions can improve the resuscitation success rate of patients with cardiac arrest. Therefore, current international guidelines all require strict control of the quality of external chest compressions and put forward specific indicators for various quality parameters of external chest compressions. However, studies have shown that manual compressions rarely meet the requirements of the guidelines, even for trained individuals.

[0004] Therefore, there is an urgent need for a device that is easy to use, non-invasive, and accurately measures life information such as blood flow during cardiac arrest to evaluate the quality of treatment, and can manually or automatically adjust the operation of the treatment device through feedback parameters to improve the treatment rate and achieve better treatment effects.

[0074] Embodiment 1

[0075] An embodiment of the present application provides a cardiac arrest treatment device 10 (hereinafter referred to as the treatment device) based on ultrasonic Doppler feedback technology. The device includes:

[0076] A first monitoring module 11 for monitoring the blood flow condition of the blood vessels in the neck of a target organism;

[0077] And / or, a second monitoring module 12 for monitoring the blood oxygen condition of the blood vessels in the neck of the target organism;

[0078] An acquisition module 13 for acquiring the blood supply and / or oxygen supply of the target organism according to the blood flow condition and the blood oxygen condition;

[0079] A cardiopulmonary resuscitation compression module 14, and / or a ventilation module 15, and / or a defibrillation module 16, wherein:

[0080] The cardiopulmonary resuscitation compression module 14 is used to adjust the compression depth or compression frequency according to the blood supply and / or the oxygen supply;

[0081] The ventilation module 15 is used to adjust the ventilation frequency during cardiopulmonary resuscitation compression according to the blood supply and / or the oxygen supply;

[0082] The defibrillation module 16 is used to perform a defibrillation operation in the case of a defibrillable rhythm.

[0083] It can be understood that the target organism can be a human being. Hereinafter, the human being is mainly taken as an example for introduction. It can be understood that the technical solution of the present application can also be used for other organisms, which will not be elaborated.

[0084] It can be understood that the first monitoring module 11 can be provided by an ultrasonic Doppler blood flow monitoring device 71, and the second monitoring module 12 can be provided by a multi-parameter monitor 72. It can be understood that this is not limited thereto.

[0085] It can be understood that the cardiopulmonary resuscitation compression module 14 can be provided by a mechanical resuscitation compressor 73, the defibrillation module 16 can be provided by a defibrillator 74, and the ventilation module 15 can be provided by a ventilator 75. It can be understood that this is not limited thereto.

[0086] It can be understood that the defibrillation module 16 is also used to acquire the heart rhythm of the target organism to perform a defibrillation operation in the case of a defibrillable rhythm.

[0087] It can be understood that the first monitoring module 11, the second monitoring module 12, the acquisition module 13, the cardiopulmonary resuscitation compression module 14, the defibrillation module 16 and the ventilation module 15 can be communicatively connected in whole or in part.

[0088] In the embodiments of the present application, by setting the first monitoring module 11, the second monitoring module 12, and the acquisition module 13, the blood flow condition and blood oxygen condition of the blood vessels in the neck of the target organism are monitored, and physiological parameters such as the blood supply and / or oxygen supply of the target organism are acquired according to the blood flow condition and the blood oxygen condition; the cardiopulmonary resuscitation pressing module 14, and / or the defibrillation module 16, and / or the ventilation module 15 are also set, and according to the acquired physiological parameters, the operations of the cardiopulmonary resuscitation pressing module 14, and / or the defibrillation module 16, and / or the ventilation module 15 are adjusted, which can improve the rescue rate and the quality of treating cardiac arrest.

[0089] In some embodiments of the present application, the first monitoring module 11 is specifically used for:

[0090] Acquire the ultrasonic signals collected by the ultrasonic Doppler probe;

[0091] After performing envelope processing on the ultrasonic signals, obtain the blood flow condition.

[0092] It can be understood that after envelope processing, a more accurate blood flow condition can be obtained.

[0093] In some embodiments of the present application, the parameter of the blood supply is the velocity time integral (VTI), and the oxygen supply is the pulse oxygen saturation (SpO2); the cardiopulmonary resuscitation pressing module 14 is further used for:

[0094] If the VTI is lower than 20 cm, increase the pressing depth or the pressing frequency; or, if the VTI is lower than 25 cm and the SpO2 is lower than 85%, increase the pressing depth or the pressing frequency.

[0095] The velocity time integral (VTI) can better reflect the blood flow condition and can also be conveniently obtained, for example, it can be obtained non-invasively.

[0096] The pulse oxygen saturation (SpO2) is measured non-invasively and is commonly used in clinical evaluation of the oxygenation status. Compared with invasive arterial blood gas analysis (SaO2), SpO2 has the characteristics of non-invasiveness, rapidity, and continuous monitoring, and is suitable for surgery, ICU, and daily health management.

[0097] It can be understood that the VTI of normal adults can be 20 cm - 40 cm. Therefore, if the VTI is lower than 20 cm, without considering other factors, increase the pressing depth or the pressing frequency.

[0098] In the case where the VTI is less than 25 cm, since the situation is not very serious, the SpO2 also needs to be considered. For example, when the SpO2 is simultaneously less than 85%, increase the pressing depth or the pressing frequency.

[0099] In some embodiments of the present application, the cardiopulmonary resuscitation pressing module 14 is further configured to:

[0100] Obtain the age of the input target organism. If the age is between the first age threshold and the second age threshold, then:

[0101] If the VTI is less than 15 cm, increase the pressing depth or the pressing frequency; or, if the VTI is less than 18 cm and the SpO2 is less than 90%, increase the pressing depth or the pressing frequency.

[0102] Specifically, according to medical knowledge, the first age threshold can be 1 year old, and the second age threshold can be 8 years old. For children older than eight years old, their corresponding blood flow conditions or blood oxygen conditions are close to those of adults. Therefore, they are not judged separately.

[0103] The normal value of the VTI for children aged 1 - 8 years old can be 15 cm - 25 cm. Therefore, for the same reason as above, if the VTI is less than 15 cm, there is no need to consider other factors, and increase the pressing depth or the pressing frequency.

[0104] In the case where the VTI is less than 18 cm, since the situation is not very serious, the SpO2 also needs to be considered. For example, when the SpO2 is simultaneously less than 90%, increase the pressing depth or the pressing frequency.

[0105] It should be noted that for children, their blood flow conditions or blood oxygen conditions are not as stable as those of adults. More clinical doctors need to judge according to the specific situation. The cardiac arrest treatment device 10 in the embodiments of the present application is only for reference, and the reference significance is less than that of adults.

[0106] In some embodiments of the present application, the parameter of blood supply is the blood flow pulsation frequency, and the cardiopulmonary resuscitation pressing module 14 is further configured to:

[0107] If the blood flow pulsation frequency is less than 90, increase the pressing frequency;

[0108] Or, if the blood flow pulsation frequency is less than 100 and the SpO2 is less than 85%, increase the pressing frequency.

[0109] It can be understood that in some cases, the parameter of blood supply can also be the blood flow pulsation frequency. For the same reason as above, if the blood flow pulsation frequency is less than 90, there is no need to consider other factors, and increase the pressing depth or the pressing frequency.

[0110] If the blood flow pulsation frequency is lower than 100, since the situation is not very serious, SpO2 also needs to be considered. For example, if the SpO2 is lower than 85% at the same time, increase the compression depth or compression frequency.

[0111] It can be understood that the blood flow pulsation frequency and the VTI can be combined for comprehensive judgment to obtain a more accurate judgment result.

[0112] In some embodiments of the present application, the parameter of the blood supply is the carotid artery peak velocity, and the cardiopulmonary resuscitation compression module 14 is further configured to:

[0113] If the carotid artery peak velocity is lower than 80 cm / s, increase the compression depth;

[0114] Or, if the carotid artery peak velocity is lower than 90 cm / s and the SpO2 is lower than 85%, increase the compression depth.

[0115] It can be understood that in some cases, the parameter of the blood supply can also be the carotid artery peak velocity. For the same reason as above, if the carotid artery peak velocity is lower than 80 cm / s, other factors need not be considered, and the compression depth or compression frequency is increased.

[0116] If the carotid artery peak velocity is lower than 90 cm / s, since the situation is not very serious, SpO2 also needs to be considered. For example, if the SpO2 is lower than 85% at the same time, increase the compression depth or compression frequency.

[0117] It can be understood that the carotid artery peak velocity and the VTI can be combined for comprehensive judgment to obtain a more accurate judgment result.

[0118] In some embodiments of the present application, the cardiopulmonary resuscitation compression module 14 is further configured to:

[0119] Obtain the age of the input target organism. If the age is between the first age threshold and the second age threshold, then:

[0120] If the carotid artery peak velocity is lower than 50 cm / s, increase the compression depth or compression frequency; or, if the carotid artery peak velocity is lower than 62 cm / s and the SpO2 is lower than 90%, increase the compression depth or compression frequency.

[0121] Similarly, the first age threshold can be 1 year old, and the second age threshold can be 8 years old.

[0122] The normal value of the carotid artery peak velocity of children aged 1 to 8 years can be 50 cm / s to 100 cm / s. Therefore, for the same reason as above, if the carotid artery peak velocity is lower than 50 cm / s, other factors need not be considered, and the compression depth or compression frequency is increased.

[0123] When the peak carotid artery blood flow velocity is lower than 62 cm / s, since the situation is not very serious, SpO2 also needs to be considered. For example, when the SpO2 is lower than 90% at the same time, the pressing depth or pressing frequency is increased.

[0124] It should be noted that for children, their blood flow or blood oxygen conditions are not as stable as those of adults. More often, clinicians need to judge according to specific conditions. The cardiac arrest rescue device 10 of the embodiments of the present application is only for reference, and the reference significance is less than that of adults.

[0125] In some embodiments of the present application, the ventilation module 15 is further configured to:

[0126] If the SpO2 is lower than 80%, the ventilation frequency during cardiopulmonary resuscitation is increased; or, if the SpO2 is lower than 85% and meets any of the following, the ventilation frequency during cardiopulmonary resuscitation is increased:

[0127] The VTI is lower than 25 cm;

[0128] The blood flow pulsation frequency is lower than 100;

[0129] The peak carotid artery blood flow velocity is lower than 90 cm / s.

[0130] It can be understood that the correlation between SpO2 and ventilation is greater. Therefore, when SpO2 is abnormal, it is mainly adjusted by increasing the ventilation frequency.

[0131] Same as VTI, if the SpO2 is lower than 80%, other factors need not be considered and the ventilation frequency is increased. When the SpO2 is lower than 85%, since the situation is not very serious, other situations also need to be considered. For example, when the VTI, blood flow pulsation frequency, and peak carotid artery blood flow velocity are abnormal at the same time, the ventilation frequency is increased.

[0132] In some embodiments of the present application, the device further includes:

[0133] A third monitoring module for monitoring the cerebral oxygen of the target organism;

[0134] The ventilation module 15 is further configured to:

[0135] If the cerebral oxygen is lower than 65%, the ventilation frequency during cardiopulmonary resuscitation is increased;

[0136] Or, if the cerebral oxygen is lower than 70% and meets any of the following, the ventilation frequency during cardiopulmonary resuscitation is increased:

[0137] The VTI is lower than 25 cm;

[0138] The blood flow pulsation frequency is lower than 100;

[0139] The peak carotid artery blood flow velocity is lower than 90 cm / s.

[0140] Understandably, the cerebral oxygen of the target organism is also highly related to cardiopulmonary resuscitation. Therefore, adding a third monitoring module is beneficial for better performing cardiopulmonary resuscitation.

[0141] Similar to VTI, if the cerebral oxygen is lower than 65%, regardless of other factors, increase the ventilation frequency. And in the case where the cerebral oxygen is lower than 70%, since the situation is not very serious, other situations need to be considered, such as the abnormal situations of VTI, blood flow pulsation frequency, and peak carotid artery blood flow velocity occurring simultaneously, and increase the ventilation frequency.

[0142] In some embodiments of the present application, the device further includes:

[0143] A fourth monitoring module for monitoring the end-tidal carbon dioxide of the target organism;

[0144] The ventilation module 15 is further configured to:

[0145] If the end-tidal carbon dioxide is lower than 10 mmHg, increase the ventilation frequency during cardiopulmonary resuscitation compression;

[0146] Or, if the end-tidal carbon dioxide is lower than 12 mmHg and meets any of the following, increase the ventilation frequency during cardiopulmonary resuscitation compression:

[0147] The VTI is lower than 25 cm;

[0148] The blood flow pulsation frequency is lower than 100;

[0149] The peak carotid artery blood flow velocity is lower than 90 cm / s.

[0150] Understandably, the end-tidal carbon dioxide of the target organism is also highly related to cardiopulmonary resuscitation. Therefore, adding a fourth monitoring module is beneficial for better performing cardiopulmonary resuscitation.

[0151] Similar to VTI, if the end-tidal carbon dioxide is lower than 10 mmHg, regardless of other factors, increase the ventilation frequency. And in the case where the end-tidal carbon dioxide is lower than 12 mmHg, since the situation is not very serious, other situations need to be considered, such as the abnormal situations of VTI, blood flow pulsation frequency, and peak carotid artery blood flow velocity occurring simultaneously, and increase the ventilation frequency.

[0152] In some embodiments of the present application, the defibrillation module is further configured to:

[0153] When the ECG signal obtained by the defibrillation module is a ventricular fibrillation signal or a pulseless ventricular tachycardia signal, the defibrillation operation is performed.

[0154] It can be understood that the defibrillable rhythms mainly refer to ventricular fibrillation (VF) and pulseless ventricular tachycardia (VT), and their identification relies on the following core methods:

[0155] ECG analysis: Ventricular fibrillation: manifested as irregular and disordered waveforms, without clear QRS waves or T waves; Pulseless ventricular tachycardia: wide QRS waves (>120 ms), frequency > 100 beats per minute, and no effective pulse.

[0156] The automated external defibrillator (AED) analyzes the ECG signal in real time through a built-in algorithm and automatically triggers a defibrillation recommendation.

[0157] In this embodiment, the ECG analysis can be provided by the ultrasonic Doppler blood flow monitoring device 71 or the multi-parameter monitor 72.

[0158] In some embodiments of the present application, the defibrillation module is further configured to:

[0159] In any of the following situations, the defibrillation operation is suspended:

[0160] The ECG signal obtained by the defibrillation module is a non-ventricular fibrillation signal or a non-pulseless ventricular tachycardia signal;

[0161] The waveform of the blood flow in the neck vessels is a normal waveform.

[0162] At this time, in order to avoid misjudgment, sometimes, simply judging and directly defibrillating based on having a defibrillable rhythm, such as an automated external defibrillator, may misjudge an ordinary patient as having cardiac arrest and perform defibrillation, harming the patient. And the waveform of the blood flow in the neck vessels is a good auxiliary judgment means, which can reduce misjudgment.

[0163] To more clearly understand the cardiac arrest treatment device 10 based on ultrasonic Doppler feedback technology provided by the embodiments of the present application, the execution process of the cardiac arrest treatment device 10 based on ultrasonic Doppler feedback technology provided by the embodiments of the present application will be introduced below. Figure 2 It is a schematic flowchart of the execution process of the cardiac arrest treatment device 10 based on ultrasonic Doppler feedback technology provided by the embodiments of the present application.

[0166] Step 203: Adjust the compression depth or compression frequency according to the blood supply and / or the oxygen supply; and / or, adjust the ventilation frequency during cardiopulmonary resuscitation compression according to the blood supply and / or the oxygen supply.

[0167] Step 204: Perform defibrillation operation in case of a shockable rhythm.

[0168] Figure 3 The figure is a detailed flowchart of the execution process of the cardiac arrest treatment device 10 based on the ultrasonic Doppler feedback technology provided by the embodiments of the present application. Refer to Figure 3 As shown, the execution process may include:
