Description

CPR Simulator using mannequin

The present invention relates to a CPR simulator. Specifically, it relates to a CPR simulator using a mannequin.

CardioPulmonary Resuscitation (CPR) is an emergency treatment that artificially circulates blood and helps breathing when a heart attack occurs. The basic steps of CPR are the awareness check step to check the patient's condition, the help and report step to call the emergency center by immediately calling for help from nearby people when it is confirmed that the patient is not conscious, and whether breathing is present or not. Respiratory check step to determine the heart rate, pulse check step to check the pulse of the carotid artery, chest compression step to compress the heart of a patient whose heart has stopped, Airway to lift the chin by tilting the head to prevent airway obstruction due to the relaxation of the tongue muscle It proceeds in a repeating stage of chest compressions and artificial respiration, in which the acquisition phase, artificial respiration in which air is blown into the lungs of the patient who has stopped breathing, and then chest compressions and artificial respiration are repeatedly performed until paramedics arrive at the scene. .

Respiratory check is the process of determining the presence or absence of respiration in the reaction check step. If there is no response after confirming the response, the general public should report it to the emergency center and determine whether breathing is present or abnormal according to the guidance of the emergency medical counselor. If breathing is not found or abnormal, chest compressions should be started immediately.

Medical personnel should check the response and determine whether breathing is present or abnormal, and if there is no response and it is judged that breathing is not normal, it should be recognized as cardiac arrest.

Cardiac arrest is an important respiration that requires judgment during abnormal respiration. Cardiac arrest can occur in about 40% of patients in the first minute after cardiac arrest, and recognizing cardiac arrest as a sign of cardiac arrest is a very important factor for promptly performing CPR and increasing the resuscitation success rate.

If there is no reaction but normal breathing occurs, take a recovery position to prevent aspiration of foreign objects in the mouth.

The airway securing stage is the stage before artificial respiration. Put one hand on the cardiac arrest patient's forehead and apply pressure with the palm of the hand to tilt the patient's head back, and pull the lower jaw bone part toward the head with the fingers of the other hand to support the chin. Use the method of tilting the head back, tilting the head and raising the chin.

Artificial respiration is an important element in CPR, and effective artificial respiration is essential for survival of cardiac arrest patients. In the artificial respiration method, artificial respiration is carried out over 1 second, and breathing is performed at a respiration volume of 500 to 600 ml, which is enough to visually confirm chest rise. During chest compressions, be careful not to perform artificial respiration at the same time, and avoid over-ventilating through artificial respiration.

In order to effectively perform CPR in case of an emergency, training using a simulator has become common.

However, in the prior art, there is a problem in that the feedback on whether the operator performing CPR using a mannequin presses at the correct position and pressurizes to the correct depth is insufficient.

c. The environment settings are as follows.

Environment setting is planned in 4 categories. You can select the desired content for each category.

Preferences can be accessed easily by clicking the gear-shaped icon at the top right of the menu.

The following 5 types of background selection are possible, for example.

The screen division is, for example, the following four types are possible.

In addition, the battle can also be implemented as follows.

First, the contents of the CPR manikin-linked cardiac blood flow brain transfer image are as follows (see FIG. 1 ).

1. The concept of priming water during chest compression on a mannequin is designed to depict the delivery of blood from the heart to the brain.

2. CPR manikin linked heart blood flow brain transfer image (animation) was implemented.

Next, the contents of the mannequin-linked CPR battle are as follows (see FIG. 2).

1. A CPR game that moves one space at an appropriate position, speed, and pressure

2. The race must be completed within the designated time, and if there is no pressure response for more than 10 seconds, it will end.

3. For each race, if the race is successfully completed, the record is displayed.

4. Record the highest score.

Next, the contents related to the environment setting are as follows (refer to FIG. 3).

1. You can choose from 5 basic environments.

2. In addition to the default environment, you can change the background by loading an image. This function creates a new environment by uploading an image after selecting a character. This function is a function that can increase the educational effect by creating an environment suitable for various environments and trainees.

Next, the contents of the 10-second stop danger indication are as follows (see FIG. 4).

1. If chest compressions are not performed for more than 10 seconds in the middle of CPR, the patient may be at great risk. (According to the 2019 AHA guidelines in the United States)

2. For this reason, the 10-second danger display (red all lights) function was applied to the CPR program.

Next, the contents of the world's first rib injury simulator function during CPR are as follows (see FIG. 5).

1. The rib damage, which occurs about 40% of the actual first aid situation, is converted into data and applied to the simulator.

2. It is a program that can predict and educate in advance about rib damage caused by excessive chest compression or incorrect compression position.

3. In case of rib damage, real-time damaged rib image display.

4. In the final score, indicate the cause of the damage to the ribs, etc.

Next, the contents of the pressure position zero point function are as follows (see FIG. 6 ).

This is about the result of the compression position in the test, and the result of comparison with the original position is analyzed by creating a pressure distribution diagram.

Next, the contents of the pressure depth result analysis table are as follows (see FIG. 7 ).

The pressure depth result shows the pressure result by time period, the pressure underpressure result, the overpressure result display, and the setting of the training direction.

The recommended extended chest compression depth for adults is a minimum of 2 inches (5 cm) and should not exceed 2.4 inches (6 cm).

While the 2015 Guidelines Update recommends a compression depth of at least 2 inches (5 cm), exceeding the upper limit of compression depth (2.4 inches (6 cm)) can potentially cause adverse effects.

The most common side effect is a chest fracture, accounting for about 40% of all CPR personnel and first aid personnel. However, CPR should be maintained even in situations such as chest fractures. This is because cardiac arrest is certain when chest compressions are stopped.

A chest fracture occurs due to two factors.

1. Depth of compression

2. Compression position

First, it becomes a factor in the case of compression depth (6cm) or more.

Second, the probability of fracture increases even if the compression depth does not reach 6 cm when the compression position is not in the correct position.

In conclusion, in order to simulate the chest fracture phenomenon, when chest compression is performed, the exact compression depth and compression location are checked to inform the chest fracture status, etc., and to help students learn correct CPR skills themselves.

In addition, a flowchart related to CPR is shown in FIG. 8 .
