Description

[Technical Field]

[0001] The present invention relates to a cardiopulmonary resuscitation device and automatic cardiac shock device fusion system that combines a cardiopulmonary resuscitation device and an automatic cardiac shock technique, and a control algorithm for the same. [Background technology]

[0002] Cardiopulmonary resuscitation (CPR) is a technique that involves repeating a series of steps, such as chest compressions, maintaining the airway, and artificial respiration. More specifically, when a patient is suspected of cardiac arrest, the first thing to do is to check the safety of the scene, check the person's response and breathing, then request help from those around and notify emergency rescue agencies as soon as possible. Then, with both hands clasped, compress the center of the chest (avoiding the celiac plexus and the center of both nipples) with the thenar muscles and elbows spread apart 30 times, with compressions to a depth of 4 to 6 cm. After chest compressions, the airway is secured, and while checking to see if the chest expands, artificial respiration is performed twice, with each compression taking 1 to 2.5 seconds, and chest compressions and artificial respiration are alternated twice.

[0003] However, for ordinary people, even if they have received CPR training, when a patient experiences cardiac arrest, there are problems such as poor CPR skills, strain on the ribs, and inability to accurately grasp the depth of compressions due to variations in chest height from patient to patient.

[0004] For this reason, there are various types of cardiopulmonary resuscitation (CPR) devices. One such device is powered by compressed air or breathing gas (Jolife AB, Lund, Sweden; Lucas™). The advantage of such CPR devices is their light weight and portability. Another advantage is the elastic nature of compressed air, which makes air-powered CPR devices less traumatic to the patient's chest than devices equipped with rigid compression means. Such devices can be used as first aid equipment in life-saving situations. Furthermore, such devices can be supplied with driving gas from a suitable hospital air supply line for uninterrupted CPR shocks once the patient is admitted to hospital.

[0005] However, the cardiopulmonary resuscitation device does not have a function for analyzing the cardiac rhythm (electrocardiogram, ECG), which makes it difficult to accurately determine whether the patient is experiencing cardiac arrest.

[0006] Meanwhile, there is an automated external defibrillator (AED) that analyzes cardiac rhythm. The AED is a semi-automatic device that eliminates cardiac fibrillation. If it detects sudden cardiac arrest (SCA) through cardiac rhythm analysis, which is a phenomenon in which the heart stops beating, blood flow to various tissues is cut off, and the supply of oxygen and other vital nutrients for vital activity is cut off, it applies an external electric shock to restore the patient's cardiac rhythm to normal.

[0007] However, the automatic cardiac shock device only delivers cardiac shock based on an electric shock, so it cannot be used on critical patients, and there are problems in that it is not versatile and difficult to use on critical patients, making it difficult to restore the heart rate to normal. Summary of the Invention [Problem to be solved by the invention]

[0008] The present invention has been made to solve the above problems, and provides a control algorithm for a cardiopulmonary resuscitation device and an automatic cardiac shock fusion system that analyzes the patient's cardiac rhythm during first aid treatment and performs chest compressions and an electric shock in parallel or only chest compressions depending on the cardiac rhythm analysis result, thereby allowing the patient's cardiac rhythm to return to normal.

[0009] Another object of the present invention is to provide a control algorithm for a cardiopulmonary resuscitation device and an automatic cardiac shock absorber fusion system in which a chest compression unit for compressing a patient's chest is slidable in order to accurately compress the patient's chest.

[0010] However, the object of the present invention is not limited to the above-mentioned object. [Means for solving the problem]

[0011] To achieve the above object, a control algorithm of a cardiopulmonary resuscitation device and an automatic cardiac shock absorber fusion system according to one embodiment of the present invention includes a first step in which a control unit determines whether the cardiopulmonary resuscitation device and the automatic cardiac shock absorber fusion system are set to an automatic cardiac shock mode and / or a chest compression mode; a second step in which the control unit determines whether a plurality of electrodes or pads of an electrocardiogram measuring unit are attached to a patient's chest; and a rhythm determination and shock signal generation unit analyzes the patient's cardiac rhythm through the electrocardiogram measuring unit and determines whether the cardiac rhythm is a shockable rhythm or a nonshockable rhythm. a third step of determining that the patient's cardiac rhythm is a shockable rhythm; a fourth step of lowering a chest compression unit into contact with the patient's chest after analyzing the patient's cardiac rhythm and compressing the patient's chest; a fifth step of determining whether an input signal is to be input to a shock button by the control unit if the rhythm determination and shock signal generation unit determines that the patient's cardiac rhythm is a shockable rhythm; a sixth step of causing an electric shock unit to generate high-voltage energy through the rhythm determination and shock signal generation unit to administer an electric shock to the patient if an input signal is input to the shock button; and a seventh step of controlling the electric shock unit to internally discharge the high-voltage energy if it is determined that an input signal is not input to the shock button by the control unit.

[0012] The first step includes step 1-1 in which a control button of the control unit is input, step 1-2 in which the control unit determines whether an input signal is input to a rhythm analysis button for operating the electrocardiogram measurement unit and the rhythm judgment and shock signal generation unit, and step 1-3 in which the control unit determines whether an input signal is input to the shock button.

[0013] The first step further includes steps 1-4 in which the control unit controls a chest compression therapy method for the patient when it is determined that no input signal is input to the shock button.

[0014] Steps 1-4 include the steps of setting the compression mode of the chest compression unit to a continuous compression mode in which the chest of the patient is continuously compressed, or a 30:2 compression mode in which 30 chest compressions and two artificial respirations are performed in parallel, using a compression mode setting button of the control unit; setting the compression depth of the chest compression unit using a compression depth setting button of the control unit; and setting the compression speed of the chest compression unit using a compression speed setting button of the control unit.

[0015] In the fourth step, the chest compression unit compresses the patient's chest at the compression depth and compression speed set by the compression depth setting button and the compression speed setting button, based on the continuous compression mode or the 30:2 compression mode set by the compression mode setting button.

[0016] The third step includes the steps of: the electrocardiogram measurement unit detecting an electrocardiogram signal from the patient through the plurality of electrodes or pads attached to the patient's chest, amplifying the detected electrocardiogram signal, removing noise from the amplified electrocardiogram signal, and converting the amplified electrocardiogram signal into a digital signal; and the rhythm determination and shock signal generation unit analyzing the patient's cardiac rhythm based on the digital signal received from the electrocardiogram measurement unit.

[0017] The sixth step includes a step in which the electrical shock unit receives from the rhythm determination and shock signal generation unit an electrical shock signal that the rhythm determination and shock signal generation unit generates when it determines that the patient's cardiac rhythm is a shockable rhythm, and a step in which, when an input signal is input to the shock button, the electrical shock unit generates high-voltage energy based on the electrical shock signal and delivers an electrical shock to the patient.

[0018] In the seventh step, when the notification unit outputs a voice guide to notify that no input signal is being input to the shock button, the electric shock unit discharges the high voltage energy internally.

[0019] In the seventh step, when the alarm unit outputs no input signal to the shock button, outputs a voice guide instructing the user to input an input signal to the shock button, and then outputs a voice guide indicating that the automatic cardiac shock mode is canceled, the electric shock unit discharges the high-voltage energy internally.

[0020] The patient is subjected to chest compression and an electric shock depending on the timing of operation of the electric shock unit and the chest compression unit. alternating Or add them at the same time.

[0021] The control unit controls the chest compression unit to stop chest compression just before the rhythm determination shock signal generation unit determines the rhythm and to continue chest compression just after the rhythm determination during the repeated process of measuring the patient's electrocardiogram, determining rhythm, compressing chest, administering electric shock, and discharging high-voltage energy internally.

[0022] According to another aspect of the present invention, there is provided a combined system of a cardiopulmonary resuscitation device and an automatic cardiac shock device, comprising: a support base for supporting a patient's back; a support base having one end connected to each side edge of the support base; and a hood connected to one side of the support base and having a control unit connected to a chest compression unit for compressing the patient's chest and having a shock button. The support base further comprises: an electrocardiogram measurement unit that detects an electrocardiogram signal from the patient, amplifies the signal, removes noise from the amplified electrocardiogram signal, and converts the signal into a digital signal; a rhythm determination and shock signal generation unit that receives the digital signal from the electrocardiogram measurement unit, analyzes the patient's cardiac rhythm using the digital signal, determines whether the patient's cardiac rhythm is a shockable rhythm or a non-shockable rhythm, and generates an electric shock signal if the patient's cardiac rhythm is determined to be the shockable rhythm; and an electric shock unit that receives the electric shock signal from the rhythm determination and shock signal generation unit, and emits voltage energy from electrodes or pads attached to the patient's chest, thereby delivering an electric shock to the patient.

[0023] The control unit controls at least one of the chest compression unit, the electrocardiogram measurement unit, the rhythm determination and shock signal generation unit, and the electric shock unit to be operated.

[0024] The control unit controls the chest compression unit to stop chest compression just before the rhythm determination shock signal generation unit determines the rhythm and to continue chest compression just after the rhythm determination during the repeated process of measuring the patient's electrocardiogram, determining rhythm, compressing chest, administering electric shock, and discharging high-voltage energy internally.

[0025] The patient is subjected to chest compression and an electric shock depending on the timing of operation of the electric shock unit and the chest compression unit. alternating Or add them at the same time. [Effects of the Invention]

[0026] The present invention is highly versatile as it combines a cardiopulmonary resuscitation device and an automated cardiac shock machine to provide chest compressions and electrical shocks to a patient in one system.

[0027] The present invention also allows the sliding movement of the CPR device to accurately compress the patient's chest.

[0028] However, the effects of the present invention are not limited to those described above. [Brief explanation of the drawings]

[0035] FIG. 1 is a perspective view showing a cardiopulmonary resuscitation device and an automatic cardiac shocker fusion system according to one embodiment of the present invention; FIG. 2 is a schematic diagram showing a cardiopulmonary resuscitation device and an automatic cardiac shocker fusion system according to one embodiment of the present invention; and FIG. 3 is a block diagram showing a control unit according to one embodiment of the present invention.

[0036] As shown in FIGS. 1-3, the cardiopulmonary resuscitation device and automatic cardiac shock absorber fusion system of the present invention includes a cradle 100, a support base 200, and a hood 300.

[0037] The cradle 100 is shaped to support the back of a patient (acute cardiac arrest, cardiac fibrillation, etc.).

[0038] The receiving base 100 includes a sliding guide 110 for sliding the support base 200 and the hood 300, which are the cardiopulmonary resuscitation device, and a stopper 120 for fixing the positions of the support base 200 and the hood 300.

[0039] In addition, the cradle 100 has an internal space formed on the side thereof into which the frame 115 provided on the sliding guide 110 can be retracted in order to adjust the height of the chest compression unit 310 .

[0040] The sliding guides 110 are provided on both side edges of the receiving base 100 and are slidably coupled to one end and the other end of the support base 200, allowing the support base 200 to slide forward or backward.

[0041] As shown in FIG. 2(b), which is an enlarged view of area A in FIG. 2(a), the sliding guide 110 is provided with a frame 115 that can be retracted into the cradle 100 or pulled out from the cradle 100, allowing the distance between both ends of the support base 200 to be adjusted, thereby allowing the height of the chest compression unit 310 to be adjusted.

[0042] The height of the chest compression unit 310 can be adjusted to prevent a situation in which the chest compression unit 310 cannot compress the chest of a particular patient, since each patient has a different body shape.

[0043] The stopper 120 is provided on the sliding guide 110 and has a shape that can be fastened to one end and the other end of the support base 200, so that the stopper 120 is fastened to one end and the other end of the support base 200, and by fastening to one end and the other end of the support base 200, the positions of the support base 200 and the hood 300 are fixed.

[0044] The cradle 100 further includes an electrocardiogram measuring unit 130, a rhythm determining and shock signal generating unit 140, and an electric shock unit 150 for providing electric shock therapy to the patient.

[0045] The electrocardiogram measuring unit 130 is connected to the rhythm determination and impulse signal generating unit 140 and the control unit 320 described below. When operated by the control unit 320, the electrocardiogram measuring unit 130 detects an electrocardiogram signal from a patient, amplifies the detected electrocardiogram signal, removes noise from the amplified electrocardiogram signal, converts the amplified electrocardiogram signal into a digital signal, and transmits the digital signal to the rhythm determination and impulse signal generating unit 140.

[0046] The electrocardiogram measurement unit 130 includes an amplifier that amplifies an analog electrocardiogram signal when it is detected, a filter that removes noise from the electrocardiogram signal amplified by the amplifier, and an A / D converter that converts the electrocardiogram signal from which noise has been removed by the filter into a digital signal.

[0047] The electrocardiogram measurement unit 130 comprises a plurality of electrodes built into the support base 100 or pads attached to the patient in order to detect an analog electrocardiogram signal from the patient, thereby detecting an electrocardiogram signal from the patient whose back is supported on the support base 100.

[0048] Here, the process of detecting the patient's electrocardiogram signal using a plurality of electrodes or pads is a conventional process, and therefore a description thereof will be omitted.

[0049] The rhythm determination and shock signal generation unit 140 is built into the cradle 100 and is connected to the electrocardiogram measurement unit 130 so as to be operated together when the electrocardiogram measurement unit 130 is operated by the control unit 320, thereby receiving digital signals from the electrocardiogram measurement unit 130.

[0050] When the rhythm determination and shock signal generation unit 140 receives a digital signal from the electrocardiogram measurement unit 130, it analyzes the patient's cardiac rhythm using the digital signal to determine whether the patient's cardiac rhythm is a shockable rhythm or a non-shockable rhythm. If the patient's cardiac rhythm is determined to be a shockable rhythm, it generates an electric shock signal and sends the electric shock signal to the electric shock unit 150 when the electric shock unit 150 is activated.

[0051] The electrical shock unit 150 is coupled to the rhythm determination and shock signal generation unit 140 and receives an electrical shock signal from the rhythm determination and shock signal generation unit 140 when it is operated by the control unit 320 if the rhythm determination and shock signal generation unit 140 determines that the patient's cardiac rhythm is a shockable rhythm.

[0052] In the following description, it is assumed that the electric shock unit 150 has a plurality of electrodes.

[0053] When the electrical shock unit 150 receives an electrical shock signal from the rhythm determination and shock signal generation unit 140, it generates high-voltage energy and releases it to the first defibrillation electrode 151 and the second defibrillation electrode 152 so that high-voltage electrical shocks occur at each of the first defibrillation electrode 151 and the second defibrillation electrode 152.

[0054] The first defibrillation electrode 151 and the second defibrillation electrode 152 are preferably attached to the patient's chest so that an electric shock can be applied to the patient. For example, the first defibrillation electrode 151 is attached under the patient's right collarbone to apply an electric shock to the patient, and the second defibrillation electrode 152 is attached to the patient's left side, next to the nipple, to apply an electric shock to the patient.

[0055] The first defibrillation electrode 151 and the second defibrillation electrode 152 are provided with a sensor (not shown) that detects whether they are attached to the patient's chest, and the sensor (not shown) transmits data regarding whether they are in contact with the patient's chest to the control unit 320.

[0056] The support base 200 and the hood 300 are provided in the combined system of the cardiopulmonary resuscitation device and automatic cardiac shock absorber of the present invention to operate as a cardiopulmonary resuscitation device for compressing the patient's chest.

[0057] The support base 200 is coupled to a sliding guide 110 so that a chest compression unit 310 (described later) can move to a position where it compresses the patient's chest. In the present invention, the shape for supporting the hood 300 is arched, but is not limited to this.

[0058] The support base 200 has one end and the other end movably connected to a pair of sliding guides 110, so that it can move forward or backward around the sliding guides 110 as an axis, or the distance between the two ends can be adjusted by retracting and pulling out the frame 115.

[0059] Here, it is preferable that the movement of the support base 200 forward and backward and the adjustment of the distance between both ends are performed before the chest compression unit 310 compresses the patient's chest. When the user providing first aid to the patient has moved the chest compression unit 310 to the position where it will compress the patient's chest, one end and the other end are fastened together by a pair of stoppers 120, thereby fixing the chest compression unit 310 in the position where it will compress the patient's chest.

[0060] In addition, the support base 200 has a shape such that one end and the other end can be attached and detached from a pair of sliding guides 110, and is freely detachable from the pair of sliding guides 110. By attaching and detaching, the support base 200 and the hood 300 can be attached and detached from the receiving base 100, allowing for separate use of the cardiopulmonary resuscitation device.

[0061] The hood 300 is attached to one side of the support base 200, more specifically, to the arch crown of the arch-shaped support base 200, and is connected to a chest compression unit 310 for compressing the patient's chest. A control unit 320 is provided to control the operation of the cardiopulmonary resuscitation device and the automatic cardiac shock fusion system.

[0062] Before compressing the patient's chest, the chest compression unit 310 is separated from the patient's chest, and is operated by the control unit 320 to move down to a position where it will compress the patient's chest, and then compresses the patient's chest.

[0063] The chest compression unit 310 provides first aid to the patient by compressing the patient's chest in either a continuous compression mode in which the patient's chest is continuously compressed, or a 30:2 compression mode in which the patient's chest is compressed 30 times and then two artificial respirations are given, thereby compressing the patient's chest and providing first aid based on chest compressions.

[0064] The chest compression unit 310 is connected to the electric shock unit 150. alternating Or they operate simultaneously.

[0065] That is, the cardiopulmonary resuscitation device and automatic cardiac shock device fusion system of the present invention can perform chest compression and electric shock to the patient through one system by operating the electric shock unit 150 and the chest compression unit 310 at the same time. alternating At the same time, it has the effect of being highly versatile.

[0066] The control unit 320 is provided with a plurality of buttons for operating at least one of the chest compression unit 310, the electrocardiogram measurement unit 130, the rhythm determination and shock signal generation unit 140, and the electric shock unit 150.

[0067] The plurality of buttons, for example, include a power button for turning on / off the power of the cardiopulmonary resuscitation device and automatic cardiac shock device fusion system of the present invention, a control button for setting the mode of the cardiopulmonary resuscitation device and automatic cardiac shock device fusion system to the automatic cardiac shock mode or the chest compression mode, a stop button for stopping the operation of the chest compression unit 310, a compression mode setting button for causing the chest compression unit 310 to perform chest compression (CPR) or for setting the chest compression mode of the chest compression unit 310, a compression depth setting button for setting the chest compression depth of the chest compression unit 310, a compression rate setting button for setting the chest compression rate (number of times) of the chest compression unit 310, a rhythm analysis button for operating the electrocardiogram measurement unit 130 and the rhythm determination and shock signal generation unit 140, and a shock button for operating the electric shock unit 150.

[0068] When an input signal is input to the power button and the power of the cardiopulmonary resuscitation device and automatic cardiac shock device fusion system of the present invention is turned on, the control unit 320 initializes the settings and performs a self-test to determine whether the device is operating normally. When the cardiopulmonary resuscitation device and automatic cardiac shock device fusion system of the present invention is turned on, when an input signal is input to the power button, the control unit 320 initializes the settings and turns off the power of the cardiopulmonary resuscitation device and automatic cardiac shock device fusion system of the present invention.

[0069] When the compression mode setting button is in the continuous compression mode, the control unit 320 controls the chest compression unit 310 to compress the patient's chest, and when the continuous compression mode is not in the continuous compression mode, the control unit 320 controls the chest compression unit 310 to perform two artificial respirations after 30 compressions of the patient's chest.

[0070] When an input signal is input to the compression depth setting button, the control unit 320 can control the chest compression unit 310 so that the patient's chest is compressed to at least one depth of 4 cm, 4.5 cm, 5 cm, or 5.5 cm.

[0071] Furthermore, the control unit 320 can control the chest compression unit 310 so that when an input signal is input to the compression depth setting button in the initialization state, the patient's chest is compressed 5 cm, when a signal is input thereafter, the patient's chest is compressed 5.5 cm, when a signal is input again, the patient's chest is compressed 4 cm, and when a signal is input again, the patient's chest is compressed 4.5 cm.

[0072] The control unit 320 can control the chest compression unit 310 so that, when an input signal is input to the compression speed setting button, the patient's chest is compressed at least one of 100 times, 110 times, and 120 times.

[0073] Furthermore, the control unit 320 can control the chest compression unit 310 so that when an input signal is input to the compression speed setting button in the initialization state, the patient's chest is compressed 110 times, when another signal is input, the patient's chest is compressed 120 times, and when a further signal is input, the patient's chest is compressed 100 times.

[0074] FIG. 4 is a diagram showing a control algorithm of a cardiopulmonary resuscitation device and an automatic cardiac shock device fusion system according to an embodiment of the present invention, and FIG. 5 is a diagram showing a chest compression treatment process in the control algorithm of FIG.

[0075] The control algorithms in Figures 4 and 5 are used to control the cardiopulmonary resuscitation device and automatic cardiac shock device fusion system of the present invention. Therefore, even if the following content is omitted, it is preferable to understand that the operational flow process is performed by the cardiopulmonary resuscitation device and automatic cardiac shock device fusion system of the present invention.

[0076] As shown in FIG. 4, in order to provide chest compression therapy and electric shock therapy to a patient, when an input signal is input to the power button and the power is turned on, the control unit 320 initializes the settings of the cardiopulmonary resuscitation device and automatic cardiac shock device fusion system of the present invention and performs a self-test to determine whether the cardiopulmonary resuscitation device and automatic cardiac shock device fusion system of the present invention is operating normally (S1).

[0077] After initialization and self-test, the user presses the control button of the control unit 320 to control the mode of the cardiopulmonary resuscitation device and automatic cardiac shock device fusion system of the present invention in the automatic cardiac shock mode (S2).

[0078] After the control button is input, the control unit 320 can determine whether an input signal is input to the rhythm analysis button (S3).

[0079] Here, if it is determined that the rhythm analysis button is pressed (S3-YES), the control unit 320 operates the electrocardiogram measurement unit 130 and the rhythm determination and shock signal generation unit 140. Conversely, if it is determined that the rhythm analysis button is not pressed (S3-NO), the control unit 320 can determine whether the shock button is pressed by the user (S4).

[0080] At this time, if it is determined that the shock button is pressed (S4-YES), the control unit 320 operates the electric shock unit 150 to provide an electric shock to the patient; on the other hand, if it is determined that the shock button is not pressed (S4-NO), the control unit 320 can control the chest compression therapy method of the cardiopulmonary resuscitation device and automatic cardiac shock device fusion system of the present invention according to the operation flow in FIG. 5.

[0081] Meanwhile, when the initialization and self-test are completed, the notification unit built into the cardiopulmonary resuscitation device and automatic cardiac shock device fusion system of the present invention outputs voice guidance instructing the patient to remove their outer clothing and attach pads to the patient (S5).

[0082] In this case, the voice guidance is not limited to a voice guidance instructing to attach pads. If the electrocardiogram measurement unit 130 comprises multiple electrodes, a voice guidance instructing to attach multiple electrodes is output, but here, the explanation will be based on pads.

[0083] After the voice guidance is output, the user attaches the pad to the patient's chest (S6).

[0084] Here, if the control unit 320 determines that the pads are not attached to the patient's chest, the notification unit outputs a voice guide again to attach the pads to the patient's chest (S7).

[0085] On the other hand, if the control unit 320 determines that the pad has been attached to the patient's chest (S6-YES), the chest compression unit 310 descends to its initial position for compressing the patient's chest (S8), where the lower end of the chest compression unit 310 is 1 cm away from the patient's chest.

[0086] After the chest compression unit 310 is lowered, the notification unit outputs a voice guide to warn the user not to touch the patient during the treatment process (S9).

[0087] After outputting the voice guidance, the rhythm determination and shock signal generation unit 140 analyzes the patient's cardiac rhythm based on the digital signal received from the electrocardiogram measurement unit 130 (S10).

[0088] After analyzing the patient's cardiac rhythm, the chest compression unit 310 lowers into contact with the patient's chest (S11), and the chest compression unit 310 compresses the patient's chest to provide chest compression therapy (S12).

[0089] Meanwhile, once the patient's cardiac rhythm has been analyzed, the rhythm determination and shock signal generation unit 140 determines whether the patient's cardiac rhythm is a shockable rhythm (S13).

[0090] At this time, if it is determined that the patient's cardiac rhythm is one requiring shock (S13-YES), the notification unit outputs a voice guide requesting the patient to press the shock button, indicating that the patient requires electroshock therapy (S14).

[0091] The control unit 320 determines whether the user inputs an input signal to the shock button within a predetermined time (eg, 10 seconds) after the voice guidance is output (S15).

[0092] Here, if it is determined that an input signal is not input to the shock button within a predetermined time (S15-NO), the notification unit outputs a voice guide requesting input of an input signal to the shock button, since no input signal has been input to the shock button.(S17) .

[0093] After outputting the voice guidance, the control unit 320 again determines whether the user inputs an input signal to the shock button within a predetermined time (for example, 10 seconds) (S18).

[0094] At this time, if it is determined that an input signal is not input to the shock button within a predetermined time (S18-NO), the alarm unit outputs a voice guide indicating that an input signal has not been input to the shock button and that the automatic cardiac shock will be canceled.

[0095] At the same time, the control unit 320 controls the electric shock unit 150 so that the voice guidance is output and the high voltage energy generated by the electric shock unit 150 is internally discharged (S20).

[0096] On the other hand, if it is determined that the patient's cardiac rhythm is not a shock-requiring rhythm but a non-shock-requiring rhythm (S13-NO), the notification unit outputs a voice guide instructing the patient to omit the electric shock treatment process, and the control unit 320 controls the electric shock unit 150 so that the high voltage energy generated by the electric shock unit 150 is internally discharged by omitting the electric shock treatment process (S20).

[0097] As shown in FIG. 5, in order to control the chest compression therapy method for a patient, while the cardiopulmonary resuscitation device and automatic cardiac shock absorber fusion system of the present invention is operating, the control unit 320 determines whether an input signal is input to the power button (S100).

[0098] Here, the control unit 320 controls the chest compression unit 310 to stop chest compression just before rhythm determination and continue chest compression just after rhythm determination, except for the period when the rhythm determination and shock signal generation unit 140 performs rhythm determination, during the repeated process of measuring the patient's electrocardiogram, determining rhythm, chest compression, administering electric shock, and internally discharging high-voltage energy.

[0099] At this time, if it is determined that an input signal has been input to the power button (S100-YES), the control unit 320 initializes the automatic cardiac shock mode and the chest compression mode (S101), and terminates the operation of the cardiopulmonary resuscitation device and automatic cardiac shock device fusion system of the present invention.

[0100] On the other hand, if it is determined that no input signal is input to the power button (S100-NO), the control unit 320 can determine whether an input signal is input to the control button and therefore whether the cardiopulmonary resuscitation device and automatic cardiac shock device fusion system of the present invention is set to chest compression mode (S102).

[0101] Here, when the cardiopulmonary resuscitation device and automatic cardiac shock unit fusion system of the present invention is set to the chest compression mode by the control button (S102-YES), the control unit 320 stops the automatic cardiac shock mode in which an electric shock is delivered (S103), and controls the chest compression unit 310 to compress the patient's chest (S104).

[0102] Alternatively, if it is determined that no input signal is input to the control button (S102-NO), the control unit 320 determines whether an input signal is input to the stop button (S105), and if it is determined that an input signal is input to the stop button, the control unit 320 can stop the operation of the chest compression unit 310 (S106).

[0103] Also, if an input signal is not input to the stop button (S105-NO), the control unit 320 can determine whether an input signal is input to the compression mode setting button (S107).

[0104] Here, if it is determined that an input signal has been input to the compression mode setting button (S107-YES), the control unit 320 determines whether the compression mode setting button is set to the continuous compression mode (S108). If it is determined to be set to the continuous compression mode (S108-YES), the control unit 320 controls the chest compression unit 310 to operate in the continuous compression mode, which continuously compresses the patient's chest (S109). Conversely, if the continuous compression mode is not set, the control unit 320 controls the chest compression unit 310 in the 30:2 compression mode, which performs two artificial respirations after 30 compressions of the patient's chest (S110).

[0105] On the other hand, if it is determined that an input signal is not input to the compression mode setting button, the control unit 320 determines whether an input signal is input to the compression depth setting button (S111).

[0106] At this time, if it is determined that an input signal has been input to the compression depth setting button (S111-YES), the control unit 320 controls the chest compression unit 310 so that the patient's chest is compressed to at least one depth of 4 cm, 4.5 cm, 5 cm, or 5.5 cm (S112).

[0107] On the other hand, if it is determined that an input signal is not input to the compression depth setting button (S111-NO), the control unit 320 determines whether an input signal is input to the compression speed setting button (S113).

[0108] Here, if it is determined that an input signal has been input to the compression speed setting button (113-YES), the control unit 320 controls the chest compression unit 310 so that the patient's chest is compressed at least one of 100 times, 110 times, and 120 times (S114).

[0109] On the other hand, if it is determined that no input signal is input to the compression speed setting button (S113-NO), the control unit 320 controls the cardiopulmonary resuscitation device and automatic cardiac shock device fusion system of the present invention to treat the patient according to the operation flow shown in FIG. 4.
