Description

Defibrillator for CPR and Its Operation Method

The present invention relates to a defibrillator for cardiopulmonary resuscitation and its operating method, and more particularly, to a defibrillator and a method of operating the same reflecting changes in the surrounding environment.

In general, a defibrillator (Defibrillator) is a device for performing cardiopulmonary resuscitation, the automated defibrillator (Automated Extemal Defibrillator, AED) of the defibrillator is widely used. The AED is designed to automatically assess the patient's heart condition and provide an electric shock.

Because a heart attack stops blood circulation throughout your body, it can lead to death or serious brain damage if you don't take action right away. In particular, the brain can be permanently damaged even if the blood supply is interrupted for 4-5 minutes.

Cardiopulmonary Resuscitation (CPR) is an emergency treatment that artificially circulates blood and helps breathing in the event of a heart attack (cardiopulmonary resuscitation). .

In general, CPR recovers 20% of normal blood flow, while AED can recover 100%, and AED can increase the survival rate of cardiac arrest patients up to 70%.

The human heart has a command system that operates the myocardium in a certain order in order to release blood effectively. That is, the heart supplies blood to the arteries, repeating contraction and expansion in a certain order. If the heart does not move in a certain order, the heart cannot efficiently supply blood to the arteries.

Therefore, cardiopulmonary resuscitation using AED, which supplies blood to the arteries by repeatedly contracting and expanding the heart in a certain order and causes the heart to move according to the order, greatly affects the survival rate after the accident.

Cardiopulmonary resuscitation is a first aid procedure to provide oxygen to the heart, brain, and other organs when cardiac arrest occurs due to a sudden heart attack or accident. Basic CPR includes airway maintenance, ventilation, and chest compressions. .

Chest compressions are a way of assisting the patient's circulation. In cardiac arrest, blood flow to critical organs, including the brain and heart, stops, thereby compressing the patient's chest to maintain some degree of blood circulation. Chest compressions are effective with ventilation.

In an emergency patient who has a cardiac arrest due to a sudden heart attack or accident, the patient's brain begins to be irreversibly damaged if blood circulation does not occur for 4 to 6 minutes after the cardiac arrest occurs. The brain and all organs stop working and lose their lives.

Therefore, it is necessary to manufacture a defibrillator for efficient operation in consideration of the surrounding environment, but the results of research on this are still insufficient.

The disclosed structural and functional features are intended to enable those skilled in the art to specifically practice the various embodiments, and are not intended to limit the scope of the invention. The terms and phrases disclosed are intended to explain various features of the disclosed invention in an easy-to-understand manner, and are not intended to limit the scope of the invention.

In the following description of the present invention, if it is determined that the detailed description of the related known technology may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

Hereinafter, a defibrillator reflecting the surrounding environment and an operation method thereof according to an embodiment of the present invention will be described. In one embodiment, the defibrillator of the present invention may be referred to as an automatic cardiac shock, automatic external defibrillator (AED), low power cardiac shock, educational automatic defibrillator or other names having equivalent technical meanings.

1 is a view showing the functional configuration of a defibrillator according to an embodiment of the present invention. 2 illustrates an example of attaching a defibrillator and an electrode pad according to an embodiment of the present invention.

1 and 2, the defibrillator 100 includes a display 101, a storage unit 103, a shock button 105, a control unit 107, a switch 109, an electrode pad 111, and a speaker ( 113, a power button 115, a pressure sensor 117, a gyro sensor 119, an illuminance sensor 121, a sound sensor 123, and a vibration sensor 125 may be included.

When a patient in need of a heart shock occurs, the defibrillator can be started by pressing the power button 115. The switch 109 can be used to select whether the patient is an adult or a child. The proper power of the defibrillator for cardiopulmonary resuscitation in adults and children is different due to differences in physical conditions between adults and children. Due to such a difference, there is an adult and a child separately, and according to the selection of the switch 109, the electrode pad 111 can apply a voltage suitable for an adult or a child.

The electrode pad 111 may be attached to the chest of a patient requiring CPR, and may be attached to the defibrillator 100 when CPR is not performed. The electrode pad 111 is a flexible electrode pad and may be attached to the chest of the patient, as shown in FIG. 2. Attaching the electrode pad 111 to the patient and pressing the shock button 105 may apply a voltage to the patient, thereby allowing the patient to receive an electrical shock to the heart.

The pressure sensor 117 according to an embodiment of the present invention may measure the pressure intensity of chest compression applied to the chest of the patient during cardiopulmonary resuscitation. In one embodiment, as a surface pressure sensor having a predetermined area, it can be manufactured in a flexible form such as the electrode pad 111 and attached to the chest of the patient to be subjected to cardiopulmonary resuscitation by a rescuer. In addition, the pressure sensor 117 may be a pressure distribution measuring sensor in the form of an array. 2 shows a shape in which the pressure sensor 117 is attached to the chest of the patient. In one embodiment, the pressure sensor 117 may be made of an insulating material such as rubber or may be wrapped with an insulating material. As described above, the pressure sensor 117 may be protected even when the electrode pad is electrically insulated from the electrode by the insulating material. In one embodiment, when the patient is a child, the pressure sensor may be stacked on the electrode pad 111 because the position of the electrode pad 111 is the same as the position at which pressure is applied during CPR.

The gyro sensor 119 may be attached to the pressure sensor 117 to measure the position change of the chest of the patient when the pressure sensor 117 is attached to the chest and the chest is changed due to the pressure applied during CPR. In this case, the change in the position of the chest of the patient may be calculated as the pressure intensity of chest compression applied to the chest of the patient during CPR. The illuminance sensor 121 may measure a peripheral illuminance value of the defibrillator 100, that is, the amount of light. The sound sensor 123 may measure the ambient noise of the defibrillator 100, that is, the sound value. The vibration sensor 125 may measure the ambient vibration value of the defibrillator 100. In an embodiment, the pressure sensor 117, the gyro sensor 119, the illuminance sensor 121, the sound sensor 123, and the vibration sensor 125 may be included in one sensor.

The display 101 may visually display the guide information stored in the storage 103 according to the selected mode. In addition, the speaker 113 may acoustically output the guide information stored in the storage unit 103 according to the selected mode. In addition, the storage unit 103 is stored in advance the pressure range to be applied to the chest of the patient. In one embodiment, the storage unit 103 may be a conventional read only memory (ROM), random access memory (RAM), flash ROM (flash ROM), SD card, etc., but is not limited thereto. .

The display 101 or the speaker 113 may output the result determined by the controller 107 visually or audibly. If the pressure applied to the chest of the patient is outside the pre-stored pressure range, the display 101 or the speaker 113 may output the visual or audio signal. In addition, when the display 101 or the speaker 113 does not apply pressure to the center region of the chest of the patient as a result of the determination by the controller 107, the display 101 or the speaker 113 may output this visually or audibly.

In one embodiment, the defibrillator 100 may include an electrocardiogram analysis means to sense and analyze the ECG state of the patient. In addition, the defibrillator 100 may include a communication means such as Bluetooth, Wi-Fi, etc. can transmit the ECG state of the patient to other devices through communication. In one embodiment, the housing 200 may receive the storage 103 and the control unit 107.

In various embodiments of the present invention, the defibrillator 100 does not have the configurations shown in FIGS. 1 and 2, so that the defibrillator 100 has more or fewer configurations than those shown in FIGS. 1 and 2. It may be implemented as having, and different components may be integrated into one.

3 is a diagram illustrating a method of operating the defibrillator 100 for displaying a screen reflecting the surrounding environment according to an embodiment of the present invention.

Referring to FIG. 3, in step S301, the defibrillator 100 may measure at least one of an external illuminance value, a vibration value, and a sound value of the defibrillator 100. In operation S303, the defibrillator 100 may determine whether at least one of the measured illuminance value, the vibration value, and the sound value is smaller than the threshold value.

If at least one of the measured illuminance value, the vibration value, and the sound value is smaller than the first threshold value, in operation S305, the defibrillator 100 may display a smaller or darker screen than the normal mode screen. Here, the normal mode screen may refer to a screen of a default setting mode in which the size and brightness of the screen are not changed. That is, when the surroundings are dark, the vibration is weak due to vibration, or the noise is less affected by the surrounding environment, the defibrillator 100 may display a dark screen to reduce power consumption.

On the other hand, if at least one of the measured illuminance value, vibration value and sound value is not less than the first threshold value, in step S307, the defibrillator 100 at least one of the illuminance value, vibration value and sound value is the second threshold value. You can determine whether it is greater than the value. In one embodiment, the second threshold may be greater than the first threshold.

If at least one of the illuminance value, the vibration value, and the sound value is greater than the second threshold value, the defibrillator 100 may display a screen that is enlarged or brighter than the normal mode screen. For example, referring to FIG. 4 (b), the defibrillator 100 may enlarge and display a chest portion of a male patient to more clearly indicate a pad attachment position. That is, when the surroundings are bright, vibrations occur due to vibration, or noise is not concentrated, the defibrillator 100 enlarges the screen or displays the brightness brightly, and performs CPR (hereinafter, For convenience, the term "performer" may clearly recognize the displayed guidance screen and proceed with efficient CPR.

On the other hand, when at least one of the illuminance value, the vibration value, and the sound value is not greater than the second threshold value, the defibrillator 100 may display a normal mode screen. For example, referring to FIG. 4A, the defibrillator 100 may display a screen such that both male and female patients with electrode pads appear in a normal mode.

FIG. 5 is a diagram illustrating a method of operating the defibrillator 100 for displaying a compression intensity UI (user interface) corresponding to the pressure intensity of chest compressions according to an embodiment of the present invention.

Referring to FIG. 5, in operation S501, when chest pressure is detected by an operator, the defibrillator 100 may measure the pressure intensity of chest pressure. In one embodiment, the pressure intensity of chest compression may be measured by at least one of the pressure sensor 117 and the gyro sensor 119, but is not limited thereto.

In operation S503, the defibrillator 100 may determine whether the measured pressure intensity is greater than the first threshold value. Here, the first threshold value may mean the minimum intensity of chest compression effectively applied to the patient. In one embodiment, the first threshold may be set differently depending on whether the patient is an adult or a child. The first threshold may be predetermined.

If the measured pressure intensity is not greater than the first threshold value, in operation S505, the defibrillator 100 may output a voice message informing that the chest compression intensity is increased. In one embodiment, the defibrillator 100 may display a screen indicating that the chest compression strength is too weak.

On the other hand, if the measured pressure intensity is greater than the first threshold value, in step S507, the defibrillator 100 may determine whether the measured pressure intensity is less than the second threshold value. Here, the second threshold value may refer to a risk intensity of chest compression that worsens the patient's condition. In one embodiment, the second threshold may be set differently depending on whether the patient is an adult or a child. The second threshold may be predetermined.

If the measured pressure intensity is not less than the second threshold value, in step S509, the defibrillator 100 may output a voice message informing that the chest compression intensity is to be reduced. In one embodiment, the defibrillator 100 may display a screen indicating that the chest compression strength is too strong.

On the other hand, after the measured pressure intensity is smaller than the second threshold value or after performing step S505 or step S509, in step S511, the defibrillator 100 may display a compression intensity UI indicating the pressure strength. Compression strength UI indicating pressure strength is described in detail in FIGS. 6A-6C below.

In some embodiments, each step of FIG. 5 may be performed in the reverse order, or may be performed simultaneously. For example, FIG. 5 illustrates a case where step S507 is performed after step S503 is performed, but this is merely an example for description, and step S503 and step S507 may be performed regardless of the order or at the same time.

6A to 6C, each compression number UI is displayed with a number indicating the number of chest compressions at that time. That is, each compression number UI indicates the number of chest compressions to be performed at the corresponding timing. In addition, each compression number UI continuously moves from left to right on the time axis as time passes while the position of the chest compression reference line is fixed. In this case, the time interval between each compression number UI indicates a chest compression performance time interval to be performed. Through this, the performer can confirm the timing of performing the chest compression intuitively and accurately by performing the chest compression every time the compression number UI passes the chest compression baseline. This allows the attendant to easily set the chest compression rate.

For example, referring to FIG. 6A, the number of compression UI 601 is indicated by the number 1, and may indicate the first chest compression timing after the start of CPR at the moment passing the chest compression baseline along the time axis. For another example, referring to FIG. 6B, the number of compression UI 602 is displayed with the number 2, and may indicate that the second chest compression timing is the moment when the chest compression reference line is crossed along the time axis. For another example, referring to FIG. 6C, the number of compression UI 603 is displayed with the number 3, and may indicate the third chest compression timing at the moment passing the chest compression reference line along the time axis.

In addition, when chest compression is detected by the performer, the compression intensity UI is displayed at the time of performing chest compression on the time axis. In this case, the size of the compression strength UI indicates the pressure strength of the chest compression. Through this, the performer can intuitively check the size of the compression strength UI to easily match the chest compression strength. That is, by weakening the chest compression too much cardiopulmonary resuscitation, the patient dies, or by making the chest compression too strong damage to the patient's internal organs can be reduced. In addition, the position on the time axis of the compression intensity UI indicates the timing of performing chest compression by the performer. The performer can check the position of the compression strength UI in real time to confirm that he is performing chest compressions at the correct speed.

For example, referring to FIG. 6A, at the moment when the compression number UI 601 crosses the chest compression baseline, when the chest pressure pressure intensity greater than the minimum intensity and less than the risk intensity is measured, the compression intensity UI of the corresponding height is corresponding thereto. 611 may be displayed. For another example, referring to FIG. 6B, when the compression frequency UI 602 crosses the chest compression baseline, when the chest compression pressure intensity smaller than the minimum intensity is measured, the compression intensity UI having a height lower than the minimum intensity baseline ( 612 may be displayed. For another example, referring to FIG. 6C, at the moment when the compression number UI 603 crosses the chest compression baseline, if the chest compression pressure intensity greater than the risk intensity is measured, the compression intensity UI having a height higher than the risk intensity baseline is measured. 613 may be displayed.

FIG. 7 is a diagram illustrating a method of operating the defibrillator 100 for outputting a voice message for notifying a person change based on a time interval between chest compressions according to an embodiment of the present invention.

Referring to FIG. 7, in step S701, the defibrillator 100 may measure a time interval between chest compressions. Referring to FIG. 8, the defibrillator 100 may measure a time interval t between the compression intensity UI 813 indicating the 43 th chest compression performance and the compression intensity UI 814 indicating the 44 th chest compression performance. In this case, the defibrillator 100 stores time interval information between all chest compressions performed in the CPR.

In operation S703, the defibrillator 100 may determine the number of times a time interval occurs over a threshold time. Referring to FIG. 8, the threshold time may mean T _th , which is two chest compression intervals. The defibrillator 100 may determine the number of times a time interval greater than or equal to a threshold time T _th is generated for not only the time interval t but also all past chest compression time intervals.

In operation S705, the defibrillator 100 may determine whether the determined number of times is less than a first threshold value. If the determined number is not less than the first threshold value, in step S707, the defibrillator 100 may output a voice message informing the replacement of the performer. That is, when the time interval between chest compressions becomes very long, for example, as shown in FIG. 8, when the timing of chest compressions is missed four times (ie, 44, 45, 46, 47), the performer performs chest compressions. This can indicate a lack of power to perform CPR for the patient more effectively by informing the attendant to be replaced. Thereafter, in step S709, the defibrillator 100 may initialize the number of times.

On the other hand, after the determined number is less than the first threshold or after performing step S709, in step S711, the defibrillator 100 may display the compression intensity UI corresponding to the pressure intensity of chest compressions. In operation S713, the defibrillator 100 may determine whether the current ECG intensity of the patient is less than the second threshold. If the ECG intensity is smaller than the second threshold value, the process may proceed to step S701. On the other hand, if the ECG intensity is greater than the second threshold, the patient is conscious and ends the operation.

In some embodiments, each step of FIG. 7 may be performed in the reverse order, or may be performed simultaneously. For example, FIG. 7 illustrates a case in which step S709 is performed after step S707 is performed, but this is merely an example for description, and steps S707 and S709 may be performed regardless of the order or at the same time.

9 is a diagram illustrating a method of operating the defibrillator 100 for outputting a voice message informing of a person change based on the pressure strength of chest compressions according to an embodiment of the present invention.

Referring to FIG. 9, in step S901, the defibrillator 100 may measure the pressure intensity of each chest compression.

In step S903, the defibrillator 100 may determine the number of chest compressions having a pressure strength of less than or equal to the minimum intensity.

In operation S905, the defibrillator 100 may determine whether the determined number of times is less than the first threshold value. If the determined number is not less than the first threshold value, in step S907, the defibrillator 100 may output a voice message informing the replacement of the performer. That is, when a little chest compression is frequently performed, for example, as shown in FIG. 10, when the heart pressure having a pressure intensity of less than or equal to the minimum intensity is performed four times (that is, 1013, 1014, 1015, and 1016), Since the attendant may indicate that he or she lacks the power to perform chest compressions, CPR can be performed more effectively on the patient by informing the attendant of the replacement. Thereafter, in step S909, the defibrillator 100 may initialize the number of times.

On the other hand, after the determined number is less than the first threshold or after performing the step S909, in step S911, the defibrillator 100 may display the compression intensity UI corresponding to the pressure strength of the chest compressions. In operation S913, the defibrillator 100 may determine whether the current ECG intensity of the patient is less than the second threshold. If the ECG intensity is smaller than the second threshold value, the process may proceed to step S901. On the other hand, if the ECG intensity is greater than the second threshold, the patient is conscious and ends the operation.

In some embodiments, each step of FIG. 9 may be performed in the reverse order, or may be performed simultaneously. For example, FIG. 7 illustrates a case in which step S909 is performed after step S907 is performed, but this is merely an example for description, and steps S907 and S909 may be performed regardless of the order or at the same time.
