Description

[0001] AUTOMATIC EXTERNAL DEFIBRILLATOR

[0002] TECHNICAL FIELD

[0003]

[0001] The following descriptive report for the invention refers to the development of an automated external defibrillator (AED), equipped with a single multi-purpose button with three functions: on / off and defibrillation, in order to reduce the time required to operate the AED, saving valuable time in this type of operation. STATE OF THE ART

[0004]

[0002] The AED (Automated External Defibrillator), I.ON family of models, is a product capable of performing the necessary defibrillation (a high-voltage shock of up to 2500 Volts and high current) on the heart, capable of reversing cardiac arrest. This occurs because the heart is an "electromechanical machine" where electrical synchronization problems can occur. The shock in this case "resets" the cardiac electrical synchronization, in the expectation that it will return correctly.

[0005]

[0003] Cardiovascular diseases, heart attacks, high blood pressure, and diabetes have extreme consequences for the heart, leading to cardiac arrest. In medical literature, cardiac arrest is known as "Ventricular Fibrillation".

[0006]

[0004] In a cardiac arrest situation, the heart is in a state of trembling, not compressing. Because it is not compressing, it also does not generate blood flow, which leads to a lack of oxygen flow, causing cell death, primarily of brain cells (which are more sensitive).

[0007]

[0005] AED-type defibrillators are positioned in strategic locations with high traffic of people, such as shopping centers, airports, condominiums, and football stadiums, where the probability of cardiac arrest is higher.

[0008]

[0006] AEDs are designed to be used by people with little training and experience in first aid. The device itself already has voice and visual commands that assist the user in assisting the victim. The user only needs access to the device, to turn it on, and to know how to interpret the commands.

[0009]

[0007] Until the arrival / access of a defibrillator, it is highly recommended to begin chest compressions. Chest compressions aim to extend the patient's survival, as chest compression generates cardiac compression, potentially reaching up to 30% of blood flow. This is sufficient to maintain a portion of oxygen necessary to keep cells and neurons alive.

[0010]

[0008] There is an international operating guide created by the AHA (American Heart Association), which regulates worldwide the main first aid actions and the use of defibrillation, also providing guidance on the use of AEDs. In this guide, which regulates the use of AEDs, it is explained that compression is fundamental and is used in conjunction with the use of the AED, alternating defibrillation and compressions.

[0011]

[0009] The DEA works as follows:

[0012] - Turn on the device by pressing the ON button (number 1);

[0013] - Connect the adhesive pads / electrodes to the patient's chest. The device will provide audio and visual commands for the user to follow the steps;

[0014] - Wait for the AED to analyze the biological signal (electrocardiogram) and determine if it is a SHOCKABLE or NON-SHOCKABLE signal. A patient may actually be in CARDIAC ARREST or be unconscious due to low blood pressure, for example. At this stage, the user MUST NOT TOUCH THE PATIENT;

[0015] - If the AED identifies a SHOCKABLE rhythm, it will instruct the user to press the SHOCK button (number 3). At this stage, the user MUST NOT TOUCH THE PATIENT, as the AED is delivering an electric shock to the patient's chest;

[0016] - From this point, follow the rhythm identified by the AED to perform chest compressions. After 2 minutes, the AED will perform another heart rhythm analysis.

[0017]

[0010] If the user is using an adult adhesive pad and wants to use it on a child patient, the user can press the appropriate button to change the patient mode, as the device has the following energy limits: adult, 360 Joules, or child, 50 Joules. TECHNICAL PROBLEMS

[0018]

[0011] Defibrillators existing in the state of the art, with respect to their mode of activation, can be of two types:

[0019] - Contain an on / off button and another button to activate the device or defibrillate the device, or

[0020] Turn it on when you open the lid.

[0021]

[0012] The use of two separate buttons can confuse the user, reducing usability and potentially wasting their time. Remember that this type of device was created so that people without medical training can use it. Any time wasted reading instructions on how to use the AED can be the difference between life and death for a person experiencing cardiac arrest.

[0022] PROPOSED SOLUTION

[0013] Thus, due to the considerations pertinent to the problems of the technique previously discussed, it is one of the objectives of the present invention to develop an AED that has only a single on / off button and to defibrillate the device.

[0023]

[0014] Another objective of the present invention is that the single activation button provides the user with speed in service and increased usability, since the device can function completely with just one button.

[0024]

[0015] This also achieves the goal of simplifying the use of the device as much as possible for people who are not trained, in order to allow for the fastest and most correct intervention in an individual who is experiencing cardiac arrest.
