Description

Cardiopulmonary resuscitation aid apparatus by using audible and visible signals}

The present invention relates to a cardiopulmonary resuscitation assisting device for generating a sound or generating a visual indication signal to perform chest compressions and ventilation according to a predetermined cycle when performing cardiopulmonary resuscitation (CPR). In patients with endotracheal intubation and patients without endotracheal intubation, auditory or visual assistance signals are provided at different cycles, allowing medical staff to perform chest compressions and ventilation more accurately. CPR assistive device to assist.

Cardiopulmonary resuscitation is a first aid procedure designed to provide oxygen to the heart, brain and other organs when cardiac arrest occurs due to a sudden heart attack or accident.

After cardiac arrest, if the patient's blood circulation does not occur for four to six minutes, the patient's brain begins to be irreversibly damaged.If it does not occur for more than six minutes, the brain and all organs stop working and lose their life. Can be.

Chest compressions must be performed at the correct speed and depth during CPR to provide effective circulation to major organs such as the brain and heart. Excessive ventilation reduces the possibility of spontaneous circulatory recovery. It is important to implement.

Basic CPR includes airway maintenance, chest compressions and ventilation.

Airway maintenance is a way to maintain the patient's airways. In the supine position, the tongue closes the patient's airway, so the head tilt-chin lift method can keep the airway open.

Ventilation is a way of assisting the patient's breathing. Even if the airway is maintained, if there is no spontaneous breathing, the oxygen necessary for the organs is insufficient or disappeared, so oxygen can be supplied through ventilation.

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.

Cardiopulmonary resuscitation is standardized to provide accurate emergency care for cardiac arrest patients.

The standardized 2005 Common CPR Guidelines recommend that 30 chest compressions and 2 ventilations be repeated in a single cycle.

Chest compressions are recommended to be performed at depths of 4 to 5 cm or more at a rate of 100 times per minute, but in practice, chest compressions or depths often drop, and in patients with endotracheal intubation, 8 to 10 ventilations per minute are assisted. Although it is recommended that hyperventilation is often induced, hyperventilation increases intrathoracic pressure, which lowers coronary perfusion pressure and consequently reduces the possibility of spontaneous circulatory recovery.
Therefore, CPR should be performed differently between patients who have undergone endotracheal intubation and patients who have not had endotracheal intubation. At intervals, audiovisual aids were required to ensure accurate implementation.

The technical problem to be solved by the present invention is to provide a cardiopulmonary resuscitation for patients who have undergone endotracheal intubation (hereinafter referred to as 'intubation patient') and patients who do not have endotracheal intubation (hereinafter referred to as 'non-intubation patient'). It is to provide a CPR assisting device to precisely perform chest compression assist and ventilation by providing visual or auditory assistance signals to accurately distinguish CPR.

And performing a step.

Intubation patient assist signal generation step (S112 ~ S121) is a step performed when the CPR assistance mode for the intubation patient is set in the key input unit, as shown in Figure 2, Initializing the counters involved (S112), reading the preset data for the cardiopulmonary resuscitation assist operation of the intubation patient (S114), by operating the chest compression cycle counter (CT1) and ventilation cycle counter (CT2) In order to assist CPR to be performed to the intubation patient while counting the time, each counter value is compared based on a preset chest compression cycle (T1) value and a ventilation cycle (T2) value, respectively, for each corresponding cycle (T1, T2). It consists of the steps (S116 ~ S121) of repeatedly generating the first chest compression auxiliary signal and the first ventilation auxiliary signal of the.

In the intubation patient auxiliary signal generating step, a timer may further set a ventilation count counter to accumulate the number of occurrences of the first ventilation auxiliary signal, and count the number of occurrences of the first ventilation auxiliary signal in this state. While being able to be programmed to repeat the operations (S116 ~ S121) as many times as necessary.

The intubation patient auxiliary signal generation step (S112 ~ S121) is the first chest compression assist signal and the first ventilation by independently counting each predetermined chest compression cycle or ventilation cycle to assist cardiopulmonary resuscitation to be performed to the intubation patient It may be possible to change the program to generate a signal, and the first chest compression assist signal and the first ventilation assist signal generated in the intubation patient assist mode may have two different tones or different visual colors or shapes. It can be divided into display signals.

Non-intubation patient auxiliary signal generation step (S210 ~ S336) is a step performed when the CPR assistance mode for the non-intubation patient is set in the key input unit, as shown in Figure 3 and 4, Initializing counters associated with the CPR assist operation (S210), reading preset data from the memory (S212) to assist CPR to be performed to a non-intubation patient (S212), and a chest compression cycle counter (N_CT1) In order to assist the cardiopulmonary resuscitation that should be performed to the non-intubation patient while counting the time, a first chest compression assist signal is generated for each predetermined chest compression cycle (N_T1), and the occurrence frequency is generated using the chest compression count counter (N_CN1). Repeating the first chest compression auxiliary signal generating operation by a predetermined chest compression number N_N1 while counting (S214 ˜ S222); It is determined whether the last first chest compression auxiliary signal is generated, and at this point of time, generating a second chest compression auxiliary signal different from the first chest compression auxiliary signal (S310), and the first waiting time counter N_CT3. Step (S312, S314) and waiting for the first waiting time (N_T3) by counting the number of times, the number of times and the period of the second ventilation auxiliary signal to the ventilation frequency counter (N_CN2) and the ventilation cycle counter (N_CT2) It consists of the steps (S316 ~ S326) for generating the second ventilation auxiliary signal to be distinguished from the first ventilation auxiliary signal.

This non-intubation patient auxiliary signal generating step is to wait for the second waiting time (N_T4) by counting the time with the second waiting time counter (N_CT4) after the last second ventilation auxiliary signal is generated (S328, S330), the whole Counting the total number of trials with the number of trial counters N_CNT and checking whether the increased count value reaches the preset total trial count value N_CPR (S332, S334); As a result of the check, if the increased total number of trial counts does not reach the preset total number of trials, the chest compression cycle counter (N_CT1), the ventilation cycle counter (N_CT2), and the chest associated with the CPR assist operation of the non-intubated patient Chest compression cycle counter operation step (S214) for non-intubation patients after initializing compression count counter (N_CN1), ventilation count counter (N_CN2), first waiting time counter (N_CT3), and second waiting time counter (N_CT4) Returning to step S336; As a result of the checking, when the total number of trial count value N_CNT reaches the preset total number of trial count value N_CPR, a key input state is checked to determine whether the rescuer mode is 1 or rescuer mode (S338). ; Generating a message instructing to alternate the roles of a rescuer (thoracic compression operator) and a rescuer (ventilator) who perform ventilation within a preset time in the rescuer mode of 2 (S340); Waiting for a preset role change waiting time (for example, 5 seconds) for role switching (S342); It may be configured to further include the steps of returning to the initial step (S200) of the CPR assistance operation of the non-intubation patient to repeatedly execute the CPR assistance operation for the non-intubation patient. On the other hand, as a result of the key input state determination (S338), since the rescuer does not need a single rescuer to immediately return to the chest compression cycle counter operation step (S214) for the non-intubation patient through the counter initialization step (S336) The route can then be set up.

The first chest compression assist signal generated for the chest compression assist of the non-intubation patient and the second chest compression assist signal generated at the end thereof may be divided into two tones having different tones and lengths, respectively. In addition, the first chest compression assist signal for the non-intubation patient may be divided into two tones, each having a different tone depending on the number of occurrences. In addition, the second ventilation auxiliary signal generated for ventilation of the non-intubation patient may be a continuous signal that lasts for a predetermined time. In addition, the first chest compression assistance signal, the second chest compression assistance signal, and the second ventilation assistance signal generated in the non-tubular patient assist signal generation step may be distinguished by visual display signals having different colors or shapes.

The non-intubation patient auxiliary signal generation step is preferably generated by repeating the first chest compression auxiliary signal for the non-intubation patient a total of 30 times in a period of 0.6 seconds, and the second chest compression assistance signal generated last A second tone signal distinguished from the first chest compression auxiliary signals, and a second ventilation signal extending for one second after the first waiting time of two seconds from the end of the occurrence of the second chest compression auxiliary signal is 2 A secondary signal generation operation is performed for a non-tubular patient of one cycle, which is repeatedly generated twice and has a second waiting time of 1.6 seconds in the second half of the time point when the second ventilation auxiliary signal is repeated twice. Preferably, after the whole operation is repeated five times, in the rescuer mode of two, a guide message for changing the role of the rescuer who performs chest compressions and the rescuer who performs ventilation within 5 seconds is generated. In the rescuer mode of 1, the CPR assist operation is continuously performed for the non-intubated patient.

Referring to the effects of the cardiopulmonary resuscitation assisting method according to the present invention configured as described above are as follows.

2 to 4, first, the operation processor 60 determines the key input state of the key input unit 10 to determine whether the CPR assistance mode for intubation patients or CPR assistance mode for non-intubation patients (S110) to specify the operation path.

In the CPR assistance mode for intubation patients, as shown in FIG. 2, the counters associated with the CPR assistance operation of the intubation patient, that is, the chest compression cycle counter CT1 or the ventilation cycle counter CT2 of the timer 50. Initialize them (S112).

Next, data that is preset to assist cardiopulmonary resuscitation to be performed to the intubation patient, ie, chest compression cycle (T1 = 0.6 seconds) or ventilation cycle (6-8 seconds), is read from the memory 40 (S114). Serve

After reading the data from the memory, the chest compression cycle counter CT1 and the ventilation cycle counter CT2 are operated (S116) to count each time while assisting CPR in which an inpatient should be performed in an intubation patient. In order to check whether a predetermined chest compression cycle (T1) or a ventilation cycle (T2) becomes (S118, S119).

When the chest compression cycle counter CT1 becomes the chest compression cycle T1, a first chest compression auxiliary signal is generated at each time, and the chest compression cycle counter CT1 is initialized (S120). Returning to (S116), and when the ventilation period counter (CT2) value becomes the ventilation period (T2) value and generates a first ventilation auxiliary signal at each time and initializes the ventilation period counter (CT2) after (S121) The operation returns to the counter operation step S116 to repeat the operation.

In the CPR assistance mode for the non-intubation patient, as shown in FIGS. 3 and 4, the counters associated with the CPR assistance operation of the intubation patient, that is, the chest compression cycle counter (N_CT1) or ventilation of the timer 50, are shown. The cycle counter N_CT2, chest compression counter N_CN1, ventilation counter N_CN2, first and second waiting time counters N_CT3 and N_CT4, and total number of trial counters N_CNT are initialized (S210).

Next, pre-set data to assist cardiopulmonary resuscitation to be performed in non-intubated patients: chest compression cycle (N_T1 = 0.6 seconds) or ventilation cycle (N_T2 = 1 seconds), chest compressions (N_N1 = 30 times). , The number of ventilation (N_N2 = 2 times), the first waiting time (N_T3 = 2 seconds), the second waiting time (N_T4 = 1.6 seconds), the total number of trials (N_CPR = 5 times) are read from the memory 40 (S212) )

After the data is read from the memory, the chest compression cycle counter N_CT1 is operated (S214) to count the time, and it is checked whether the count value becomes the chest compression cycle value N_T1 read from the memory (S216).

When the chest compression cycle counter N_CT1 becomes the corresponding cycle N_T1, the chest compression count counter N_CN1 is increased (S218), and the increased value is the chest compression count (N_N1) value read from the memory. Check whether it is (S220).

At this time, if the chest compression count counter (N_CN1) does not reach the chest compression count (N_N1) (N branch of S220), the first chest compression auxiliary signal is generated and the chest compression cycle counter (N_CT1) is initialized. (S222) and then returns to the counter operation step (S214) to repeat the operation.

On the contrary, when the chest compression count counter N_CN1 reaches the chest compression recommended number N_N1 read from the memory (Y branch of S220), that is, when the last first chest compression assist signal is generated, the first chest compression assist A second chest compression auxiliary signal distinct from the signal is generated (S310), the time is counted by the first waiting time counter N_CT3 (S312), and the waiting (S314) is performed for the first waiting time (N_T3).

After the first waiting time has elapsed (Y branch of S314), a second ventilation auxiliary signal that lasts for a specified time is generated (S316), and when the end of the signal is confirmed (S318), the ventilation frequency counter (N_CN2) is generated. The number of times is counted (S320) to determine whether the increased counter value is the number of times of ventilation N_N2 read from the memory (S322).

At this time, if the ventilation frequency counter N_CN2 does not reach the ventilation frequency N_N2 (N branch of S322), the ventilation cycle counter N_T2 is read from the memory by counting the time (S324) with the ventilation cycle counter N_CT2. After waiting (S326) for a second time to return to the second ventilation auxiliary signal generation step (S316) it is possible to repeat the operation.

On the contrary, if the result of the check indicates that the ventilation count counter N_CN2 reaches the ventilation count N_N2 (Y branch of S322), the second waiting time N_CT4 counts the time using the second waiting time counter N_CT4 to determine the second waiting time N_T4. Wait for step (S330).

After the second waiting time has elapsed (Q branch of S330), the total number of trial counters (N_CNT) is increased each time, and the number of CPRs performed for non-intubated patients is counted, and the increased count value (N_CNT) is stored in memory. When the total number of trials read (N_CPR) is reached (Y branch in S334), the key input state is checked again to determine whether it is 1 rescuer mode or 2 rescuer mode (S338. Since the role shift is not necessary, immediately return to the chest compression cycle counter operation step (S214) for the non-intubated patient through the counter initialization step (S336). ) And a message to inform the role change of the rescuer (ventilator) performing the ventilation, i.e., to alternate the roles between the two rescuers within a preset role change waiting time (eg 5 seconds). After generating a guide message for guiding (S340) and then waiting for a predetermined waiting time (for example, 5 seconds) for the role shift (S342) to repeat the CPR assistance operation for the non-intubation patient The cardiopulmonary resuscitation assist operation of the non-intubation patient is returned to the initial stage (S200), so that the two performers can switch the role and continue to perform the CPR assist operation. It is repeated until turned off.

On the contrary, when the increased count value N_CNT is smaller than the total number of trials N_CPR read from the memory (N quarter of S334), counters related to CPR assist operation of the non-intubated patient, ie chest compression cycle counter N_CT1 ) Or chest compression counter (N_CT2), chest compression counter (N_CN1), ventilation counter (N_CN2), first waiting counter (N_CT3), second waiting counter (N_CT4) after initializing (S336) chest compression It returns to the cycle counter operation step (S214) to repeat the CPR assist operation for the non-intubation patient.
