[0002] Cardiac arrest occurs frequently in modern society, but according to statistics, the success rate of cardiopulmonary resuscitation in China is about 1.3%, which is still far behind developed countries in Europe and the United States. The survival chain proposed by the International Cardiopulmonary Resuscitation Guidelines mainly consists of four steps: chest compression-open airway-breathing-electric defibrillation. Chest compression can be replaced by a cardiopulmonary resuscitation machine. If the chest compression time is long and the person is still not resuscitated, it is best to quickly establish an advanced airway and perform mechanical ventilation through a ventilator. However, in the existing technical means, the workflow conversion between the ventilator and the cardiopulmonary resuscitation machine requires a switching time.

[0046] The main solution of the present invention is: the ventilator receives a cardiopulmonary resuscitation control signal; determines a first time period corresponding to a compression cycle and a second time period corresponding to a release cycle according to the cardiopulmonary resuscitation control signal; and controls the ventilator to perform ventilation action within the first time period or the second time period.

[0047] Since the ventilator can receive the CPR control signal sent by the CPR machine and can split the received signal into two time periods, ventilation is performed in one time period to send gas into the human lungs. After switching to another time period, the ventilator stops supplying gas, opens the exhalation valve, and discharges the gas in the human lungs. Through the cooperation of the two, the ventilator can ventilate without interruption during the compression process of the CPR machine, completely simulating normal human breathing, and the ventilator has no alarm during the whole process, and no human intervention is required, which improves the success rate of CPR.

[0048] As a way to achieve this, the ventilator can be Figure 1 .

[0049] The embodiment of the present invention relates to a ventilator, which includes: a processor 101, such as a CPU, a memory 102, and a communication bus 103. The communication bus 103 is used to realize connection and communication between these components.

[0050] The memory 102 may be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory. Figure 1 , the memory 103 as a readable storage medium may include a detection program; and the processor 101 may be used to call the detection program stored in the memory 102 and perform the following operations:

[0051] Receive cardiopulmonary resuscitation control signals;

[0052] Determine a first time period corresponding to a compression cycle and a second time period corresponding to a release cycle according to the cardiopulmonary resuscitation control signal;

[0053] The ventilation action is controlled during the second time period, wherein the ventilation action is in a stopped state during the first time period.

[0055] Get the response time of the ventilator ratio threshold;

[0056] Determining the start time and the stop time of the ventilation action according to the duration corresponding to the ventilation period in the second time period and the response duration, wherein the start time and the stop time are in the second time period;

[0057] The ventilation action is started at the start time, and the ventilation action is stopped at the stop time.

[0058] In one embodiment, the processor 101 may be used to call the detection program stored in the memory 102 and perform the following operations:

[0059] Get the preset ventilation duration;

[0060] The step of determining the start time and the stop time of the ventilation action according to the corresponding duration in the second time period and the response duration comprises:

[0061] When the sum of the ventilation duration and the response duration is less than the corresponding duration in the second time period, determining the target ventilation duration according to the corresponding duration in the second time period and the response duration;

[0062] The start time and the stop time of the ventilation action are determined according to the target ventilation duration.

[0063] In one embodiment, the processor 101 may be used to call the detection program stored in the memory 102 and perform the following operations:

[0064] When the sum of the ventilation duration and the response duration is less than the corresponding duration in the second time period, obtaining the difference between the second time period and the reserved duration and the response duration;

[0065] The difference is used as the target ventilation duration.

[0066] In the technical solution of this embodiment, the ventilator receives a cardiopulmonary resuscitation control signal; determines a first time period corresponding to a compression cycle and a second time period corresponding to a release cycle according to the cardiopulmonary resuscitation control signal; and controls the ventilator to perform ventilation actions in the first time period or the second time period. Since the ventilator can receive the cardiopulmonary resuscitation control signal sent by the cardiopulmonary resuscitation machine, and can split the received signal into two time periods, ventilation operations are performed in one of the time periods to deliver gas into the human lungs. After switching to another time period, the ventilator stops supplying gas, opens the exhalation valve, and discharges the gas in the human lungs. Through the cooperation of the two, during the compression process of the cardiopulmonary resuscitation machine, the ventilator can ventilate without interruption, completely simulating normal human breathing, and the ventilator has no alarms during the entire process, and no human intervention is required, thereby improving the success rate of cardiopulmonary resuscitation.

[0067] As a way of implementing this, a cardiopulmonary resuscitation machine can be Figure 2 .

[0068] The embodiment of the present invention relates to a cardiopulmonary resuscitation machine, which includes: a processor 201, such as a CPU, a memory 202, and a communication bus 203. The communication bus 203 is used to realize connection and communication between these components.

[0069] The memory 202 may be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory. Figure 1 , the memory 203 as a readable storage medium may include a detection program; and the processor 201 may be used to call the detection program stored in the memory 202 and perform the following operations:

[0070] receiving a breathing control signal;

[0071] Determine a third time period corresponding to the ventilation cycle and a fourth time period corresponding to the deflation cycle according to the breathing control signal;

[0072] The squeezing action is controlled during the third time period, wherein the squeezing action is in a stopped state during the fourth time period.

[0073] In one embodiment, the processor 201 may be used to call the detection program stored in the memory 202 and perform the following operations:

[0074] Get the response time of the cardiopulmonary resuscitation machine motor;

[0075] Determine the start time and the stop time of the squeezing action according to the corresponding duration in the third time period and the response duration, the start time and the stop time being in the third time period;

[0076] The squeezing action is started at the start time, and the squeezing operation is stopped at the stop time.

[0077] In one embodiment, the processor 201 may be used to call the detection program stored in the memory 202 and perform the following operations:

[0078] Get the preset extrusion duration;

[0079] The step of determining the start time and the stop time of the squeezing action according to the corresponding duration in the third time period and the response duration comprises:

[0080] When the sum of the squeezing duration and the response duration is less than the duration corresponding to the third time period, determining a target squeezing duration according to the duration corresponding to the third time period and the response duration;

[0081] The start time and the stop time of the squeezing action are determined according to the target squeezing time.

[0082] In the technical solution of this embodiment, the cardiopulmonary resuscitation machine receives a breathing control signal; determines a third time period corresponding to a ventilation cycle and a fourth time period corresponding to a deflation cycle according to the breathing control signal; controls the squeezing action in the third time period, wherein the squeezing action is in a stopped state in the fourth time period. Since the cardiopulmonary resuscitation machine can receive the breathing control signal sent by the ventilator, and can split the received signal into two time periods, and perform the squeezing operation in one of the time periods. After being converted to another time period, the cardiopulmonary resuscitation machine stops squeezing. Through the cooperation of the two, during the compression process of the cardiopulmonary resuscitation machine, the ventilator can ventilate without interruption, completely simulating normal human breathing, and the ventilator has no alarm during the whole process, and no human intervention is required, thereby improving the success rate of cardiopulmonary resuscitation.

[0083] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0084] Reference Figure 3 , Figure 3 The first embodiment of the emergency equipment control method of the present invention comprises the following steps:

[0085] Step S101, receiving a cardiopulmonary resuscitation control signal.

[0086] In this embodiment, the cardiopulmonary resuscitation control signal is sent by the cardiopulmonary resuscitation machine and received by the ventilator, wherein the cardiopulmonary resuscitation machine and the ventilator are communicatively connected. Specifically, the ventilator receives the cardiopulmonary resuscitation control signal from the cardiopulmonary resuscitation machine via communication means such as Bluetooth or WIFI.

[0087] Optionally, when the cardiopulmonary resuscitation machine is not connected or the cardiopulmonary resuscitation machine is disconnected, the ventilation duration is adjusted to 200ms. Wherein, if the conditions are met, the ventilation duration is controlled at 200ms, which is a suitable value. When it is disconnected from the cardiopulmonary resuscitation machine, the value associated with the cardiopulmonary resuscitation machine can be adjusted back to a suitable value, so that when the ventilator is used independently, there is no need to adjust back and forth.

[0088] Step S102, determining a first time period corresponding to a compression cycle and a second time period corresponding to a release cycle according to the cardiopulmonary resuscitation control signal.

[0089] In this embodiment, when a cardiopulmonary resuscitation control signal is received, the signal can be analyzed to obtain a compression cycle and a release cycle, thereby determining the first time period and the second time period.

[0090] Step S103, controlling the ventilation action during the second time period, wherein the ventilation action is in a stopped state during the first time period.

[0091] In this embodiment, the cardiopulmonary resuscitation control signal is used as the working trigger signal of the ventilator to achieve the coordination of the two. The new ventilation mode of the ventilator (ACSV) can be based on the pressure control mode or the pressure support mode, and the triggering mode is changed from the conventional pressure trigger to the cardiopulmonary resuscitation signal trigger.

[0092] Optionally, since the compression frequency is recommended to be 100-120 times / min according to the guidelines, and each compression is divided into two equally divided time periods: compression and release, ventilation can be selected at either stage of compression or release. The ventilation time is generally less than 300ms. Considering the response time of the ventilator proportional valve, the actual ventilation time is about 200ms. At this stage, a high-flow airflow is used to quickly overcome the airway pressure and deliver the gas into the human lungs. After switching to another stage, the ventilator stops supplying air, opens the exhalation valve, and discharges the gas in the human lungs.

[0093] In the technical solution of this embodiment, since the ventilator can receive the cardiopulmonary resuscitation control signal sent by the cardiopulmonary resuscitation machine, and can split the received signal into two time periods, ventilation operation is performed in one time period to send gas into the human lungs. After switching to another time period, the ventilator stops supplying gas, opens the exhalation valve, and discharges the gas in the human lungs. Through the cooperation of the two, during the compression process of the cardiopulmonary resuscitation machine, the ventilator can ventilate without interruption, completely simulating normal human breathing, and the ventilator has no alarm during the whole process, and no human intervention is required, thereby improving the success rate of cardiopulmonary resuscitation.

[0094] Reference Figure 4 , Figure 4 This is a second embodiment of the emergency equipment control method of the present invention. Based on the first embodiment, step S103 includes:

[0095] Step S1031, obtaining the response time of the ventilator ratio threshold.

[0096] In this embodiment, the ventilator ratio threshold refers to the start-up time required for the ventilator to respond to ventilation operations.

[0097] Step S1032, determining the start time and stop time of the ventilation action according to the duration corresponding to the ventilation period in the second time period and the response duration, the start time and the stop time being in the second time period.

[0098] In this embodiment, the ventilation duration is determined in combination with the ventilator ratio threshold, which can reduce the error of the ventilation time period and effectively prevent the emergency treatment effect from failing to meet expectations.

[0099] Step S1033, starting the ventilation action at the start time, and stopping the ventilation operation at the stop time.

[0100] In the technical solution of this embodiment, by selecting the ventilation time period, the ventilator can realize periodic ventilation of compression and release and stop ventilation, which can achieve: solving the problem of linkage between each compression of the cardiopulmonary resuscitation machine and the ventilator, without interrupting the rescue process, and improving the success rate of rescue; ventilation is performed for each compression, because a small amount of oxygen directly enters the lungs each time, it can increase the oxygen partial pressure in the human blood gas index, which is beneficial to the human blood oxygenation and ensures the oxygen demand after cardiac arrest. Ventilation is performed for each compression, which can effectively transport the oxygen entering the human body to various parts of the human body during the compression process, especially the brain, to ensure the oxygen supply to the brain, improve the success rate of rescue and prognosis, and improve the qualitative safety of cardiopulmonary resuscitation.

[0101] Reference Figure 5 , Figure 5 The third embodiment of the emergency equipment control method of the present invention is based on any one of the first to second embodiments, and before step S1032, it includes:

[0102] Step S1034, obtaining a preset ventilation duration;

[0103] In this embodiment, the preset ventilation duration is a ventilation duration pre-defined by the user.

[0104] Step S1032 includes:

[0105] Step S10321, when the sum of the ventilation duration and the response duration is less than the corresponding duration in the second time period, determine the target ventilation duration according to the corresponding duration in the second time period and the response duration.

[0106] In this embodiment, when the sum of the ventilation duration and the response duration is determined to be less than the duration corresponding to the ventilation period, it is determined that the preset ventilation duration can be used as the time condition for starting the ventilation operation. The target ventilation duration can be further determined based on the preset ventilation duration. For example: when the preset ventilation duration is 300ms and the response time is 100ms, when the ventilation duration of 300ms is determined to be a reasonable ventilation duration, it can be adjusted to the optimal target ventilation duration of 400ms based on the preset ventilation duration of 300ms, wherein 100ms of ventilation duration is included in 400ms.

[0107] Optionally, when the sum of the ventilation duration and the response duration is less than the duration corresponding to the ventilation period, the difference between the ventilation period and the reserved duration and the response duration is obtained; the difference is used as the target ventilation duration. The existence of the reserved duration can prevent the linkage between the ventilator and the cardiopulmonary resuscitation machine from being too tight, thereby improving the stability of cardiopulmonary resuscitation.

[0108] Step S10322, determining the start time and stop time of the ventilation action according to the target ventilation duration.

[0109] In the technical solution of this embodiment, when the ventilation period is determined, the difference between the ventilation period and the response time is used as the ventilation period. When the ventilation period is determined, the start time and stop time of the ventilator corresponding to the ventilation period can be determined within the ventilation period. This method can maximize the ventilation period.

[0110] Reference Figure 6 , Figure 6 The fourth embodiment of the emergency equipment control method of the present invention is based on any one of the first to third embodiments, and before step S101, includes:

[0111] Step S104, when a ventilation duration update request is received, determining the ventilation duration to be updated according to the update request.

[0112] In this embodiment, the update request is input by the user.

[0113] Step S105, obtaining a response time, and determining the sum of the response time and the ventilation time to be updated.

[0114] Step S106, obtaining the preset compression cycle and preset release cycle of the cardiopulmonary resuscitation machine, determining whether the sum of the time periods to be updated is less than or equal to the preset compression cycle, and determining whether the sum of the time periods to be updated is less than or equal to the preset release cycle.

[0115] Optionally, if the sum of the time periods to be updated is greater than the preset compression cycle, and / or the sum of the time periods to be updated is greater than the preset release cycle, a prompt message indicating that the ventilation request change amplitude is too large is output.

[0116] Step S107: If the sum of the to-be-updated time periods is less than or equal to the preset compression cycle, and the sum of the to-be-updated time periods is less than or equal to the preset release cycle, the to-be-updated ventilation time period is used as the ventilation time period.

[0117] In the technical solution of this embodiment, before performing cardiopulmonary resuscitation, the user can flexibly update the parameters of the ventilator and determine whether the ventilation duration to be updated is consistent with the connected cardiopulmonary resuscitation machine. If it is not consistent, it can be discovered in advance, thereby reducing the need to repeatedly confirm the adjustments you want to make during the emergency treatment process.

[0118] Reference Figure 7 , Figure 7 The fifth embodiment of the emergency equipment control method of the present invention is based on any one of the first to fourth embodiments, and before step S101, includes:

[0119] Step S108, when it is detected that the cardiopulmonary resuscitation machine is successfully connected, a preset compression cycle and a preset release cycle of the cardiopulmonary resuscitation machine are obtained.

[0120] Step S109, obtaining the ventilation duration and the response duration, determining whether the sum of the preset ventilation duration and the response duration is greater than the preset compression cycle, and / or determining whether the sum of the ventilation duration and the response duration is greater than the preset compression cycle.

[0121] Step S110: When the sum of the durations is greater than the preset compression cycle, and / or the sum of the durations is greater than the preset compression cycle, outputting a prompt message for adjusting the ventilation duration.

[0122] Optionally, when the sum of the durations is less than or equal to the preset compression cycle, and / or the sum of the durations is less than or equal to the preset compression cycle, a prompt message is outputted indicating that the current ventilation duration is adaptable to a cardiopulmonary resuscitation machine.

[0123] In the technical solution of this embodiment, when it is detected that the cardiopulmonary resuscitation machine is successfully connected, the cardiopulmonary resuscitation machine can be automatically adapted, specifically, it is ensured that the sum of the ventilation time and the response time is less than or equal to the preset compression cycle and the preset release cycle of the cardiopulmonary resuscitation machine, and the subsequent use can realize the coordinated cooperation between the cardiopulmonary resuscitation machine and the ventilator.

[0124] Reference Figure 8 , the figure shows a sixth embodiment of the emergency equipment control method of the present invention, which is applied to a cardiopulmonary resuscitation machine, based on any one of the first to fifth embodiments, including:

[0125] Step S201, receiving a breathing control signal.

[0126] In this embodiment, the breathing control signal is sent by the ventilator and received by the cardiopulmonary resuscitation machine, wherein the cardiopulmonary resuscitation machine is communicatively connected with the ventilator. Specifically, the ventilator receives the breathing control signal from the ventilator via communication means such as Bluetooth or WIFI.

[0127] Step S202, determining a third time period corresponding to a ventilation cycle and a fourth time period corresponding to a deflation cycle according to the breathing control signal.

[0128] In this embodiment, when a breathing control signal is received, the signal can be analyzed to obtain a ventilation cycle and a stop ventilation cycle, thereby determining the third time period and the fourth time period.

[0129] Step S203, controlling the squeezing action within the third time period, wherein the squeezing action is in a stopped state within the fourth time period.

[0130] In this embodiment, the breathing control signal is used as a working trigger signal of the cardiopulmonary resuscitation machine to achieve coordination between the two.

[0131] Optionally, the response time of the cardiopulmonary resuscitation machine motor is obtained; according to the corresponding time in the third time period and the response time, the start time and the stop time of the squeezing action are determined, and the start time and the stop time are in the third time period; the squeezing action is started at the start time, and the squeezing operation is stopped at the stop time. Among them, by selecting the ventilation time period, the ventilator can realize the periodic ventilation of squeezing and releasing and stop ventilation, which can achieve: solving the problem of linkage between each compression of the cardiopulmonary resuscitation machine and the ventilator, without interrupting the rescue process, and improving the success rate of rescue; ventilation is performed for each compression, because a small amount of oxygen directly enters the lungs each time, it can increase the oxygen partial pressure in the human blood gas index, which is beneficial to the human blood oxygenation and ensures the human demand for oxygen after cardiac arrest. Ventilation is performed for each compression, which can effectively transport the oxygen entering the human body to various parts of the human body during the compression process, especially the brain, to ensure the oxygen supply to the brain, improve the success rate of rescue and prognosis, and improve the qualitative safety of cardiopulmonary resuscitation.

[0132] Optionally, a preset squeezing duration is obtained; the step of determining the start and stop times of the squeezing action according to the corresponding duration in the third time period and the response duration includes: when the sum of the squeezing duration and the response duration is less than the duration corresponding to the third time period, determining the target squeezing duration according to the duration corresponding to the third time period and the response duration; and determining the start and stop times of the squeezing action according to the target squeezing duration. Wherein, when the squeezing time period is determined, the difference between the squeezing time period and the response duration is taken as the squeezing time. When the squeezing time period is determined, the start and stop times of the cardiopulmonary resuscitation machine corresponding to the squeezing time period can be determined within the squeezing time period. This method can maximize the squeezing time.

[0133] In the technical solution of this embodiment, the cardiopulmonary resuscitation machine receives a breathing control signal; determines a third time period corresponding to a ventilation cycle and a fourth time period corresponding to a deflation cycle according to the breathing control signal; controls the squeezing action in the third time period, wherein the squeezing action is in a stopped state in the fourth time period. Since the cardiopulmonary resuscitation machine can receive the breathing control signal sent by the ventilator, and can split the received signal into two time periods, and perform the squeezing operation in one of the time periods. After being converted to another time period, the cardiopulmonary resuscitation machine stops squeezing. Through the cooperation of the two, during the compression process of the cardiopulmonary resuscitation machine, the ventilator can ventilate without interruption, completely simulating normal human breathing, and the ventilator has no alarm during the whole process, and no human intervention is required, thereby improving the success rate of cardiopulmonary resuscitation.
