Description

Portable Defibrillator{PORTABLE AUTOMATED EXTERNAL DEFIBRILLATOR}

This disclosure relates to a portable defibrillator.

Recently, the number of patients with high blood pressure is rapidly increasing due to causes such as lack of exercise and work stress, along with the increase in westernized eating habits, and heart disease is on the rise.

If a patient with a chronic or underlying disease suddenly loses consciousness and collapses on the street, check the patient's heartbeat using an automatic external defibrillator provided nearby. If ventricular fibrillation or ventricular tachycardia occurs, the patient's heart rate should be checked. By momentarily applying a strong direct current electric shock of over 2,000V to the heart, a normal heartbeat can be induced again. In this regard, Republic of Korea Patent Publication No. 10-2021-0070082 presents a technology for a defibrillator that is attached to the patient's body and delivers an electric shock.

Meanwhile, the implementation of CPR is very important in that it slows down the decline in the success rate of defibrillation and increases the patient's survival rate by 2-3 times. However, ordinary people without professional training are unskilled in CPR and apply pressure to incorrect areas, causing damage to the body. There were concerns that pressure efficiency would decrease. For example, if the patient's solar plexus (xiphoid process) is incorrectly pressed during chest compressions, there is a possibility that organ damage within the abdominal cavity may occur.

In addition, the CPR operator must apply pressure to the center of the lower half of the patient's breastbone, but since it is not easy for an ordinary person who is not skilled in CPR to find the exact compression point, the center point of the imaginary line connecting both nipples of the patient is used. There were times when there was pressure.

However, the central point selected based on both nipples of the patient may not necessarily match the point that compresses the heart depending on the patient's age and body type, so even beginners can accurately identify the heart compression area and perform chest compressions to There is a need for the development of new technologies that can increase survival rates.

The technical idea of the present disclosure is to solve the above-mentioned problems, and its purpose is to provide a technology that not only allows non-experts to effectively perform CPR, but also increases the survival rate of patients using a defibrillator.

In addition, another purpose is to provide a technique that allows even beginners to accurately identify the heart compression site and perform chest compressions to prevent damage to organs within the abdominal cavity.

The problem to be solved by the present invention is not limited to the above-mentioned problem, and other technical problems not mentioned will be clearly understood by those skilled in the art from the contents described later.

In order to achieve this purpose, in one embodiment of the present invention, a portable defibrillator monitors the depth of chest compression and the speed of chest compression to determine the quality of chest compression of the operator when performing CPR by compressing the patient's chest. Resuscitation feedback device; A defibrillator that delivers an electric shock to the patient's body; A control unit that controls the operation of the defibrillator; and a battery that supplies power for driving the CPR feedback device and the defibrillator.

In addition, the CPR feedback device includes a housing having a certain area to be compressed while placed on the patient's chest; and It is installed inside the housing and may include a sensor unit that measures the chest compression depth and chest compression speed.

In addition, the defibrillator includes a pair of electrode pads provided to be attached to the patient's body, and the control unit analyzes the electrocardiogram of the patient to which the pair of electrode pads are attached and when ventricular fibrillation or ventricular tachycardia is confirmed, the battery The pair of electrode pads can be controlled to apply an electric shock to the patient using the power source.

The means for solving the above problems are merely illustrative and should not be construed as intended to limit the present invention. In addition to the exemplary embodiments described above, there may be additional embodiments described in the drawings and detailed description of the invention.

As described above, according to various embodiments of the present invention, when the operator compresses the patient's chest, the CPR feedback device monitors the quality of chest compressions in real time, so even non-experts can effectively perform CPR and defibrillation. By using the treatment in parallel, the patient's survival rate can be increased.

In addition, according to various embodiments of the present invention, the driving power of the CPR feedback device and the defibrillator is supplied by the same battery, which has the advantage of improving portability by miniaturizing the product.

In addition, according to various embodiments of the present invention, the exact chest compression area can be derived based on the patient's collarbone and solar plexus, which are areas that are relatively easy to check with the naked eye, so even a beginner can easily identify the compression area and perform chest compression. It can prevent damage to internal organs in the abdominal cavity due to incorrect pressure on the area.

Effects according to various embodiments of the present invention are not limited to the effects mentioned above, and other effects not mentioned may be clearly understood by those skilled in the art from the description of the claims.

Meanwhile, the portable defibrillator 10 according to one embodiment may further include memory (not shown). In one embodiment, location information for each pressure sensor (for example, the distance value between each pressure sensor and the clavicle attachment pad) may be pre-stored in the memory. In one embodiment, the control unit 300 selects a point (for example, the second point (P2)) with a larger distance value among the first point (P1) and the second point (P2) and selects the point and the third point (P2). The fourth point (P4), which is 1/2 of the virtual straight line connecting P3), can be derived.

In one embodiment, a series of processes for using the portable defibrillator 10 in the event of an emergency patient are described as follows.

Afterwards, the control unit 300 calculates the distance between the first point (P1) where the first pressure sensor 610 is located and the second point (P2) where the second pressure sensor 620 is located, and the first point (P1) ) and the second point (P2), the third point (P3) is derived, which is 1/2 of the virtual straight line connecting the second point (P2), and the clavicle attachment pad 500 is placed among the first point (P1) and the second point (P2). The fourth point (P4), which is 1/2 of an imaginary straight line connecting the second point (P2), which is further away from the point, with the third point (P3), is derived, and is a certain distance from the fourth point (P4). When the fifth light emitting unit 680 and the sixth light emitting unit 690 are controlled, the fifth light emitting unit 680 and the sixth light emitting unit 690 light up in red.

When the fifth light emitting unit 680 and the sixth light emitting unit 690 light up in red, the operator places the housing of the CPR feedback device 100 between the fifth light emitting unit 680 and the sixth light emitting unit 690. Attach (110) and press the housing (110) by hand to compress the patient's chest for 2 minutes. After 2 minutes, while CPR is temporarily suspended, the control unit 300 analyzes the patient's electrocardiogram, and if ventricular fibrillation or ventricular tachycardia is confirmed, the control unit 300 uses the first electrode pad 211 and the second electrode pad 212 Apply electric shock to the patient. The operator alternately performs CPR and defibrillation every two minutes until an ambulance arrives on the scene or the patient recovers and wakes up.

As described above, according to various embodiments of the present invention, when the operator compresses the patient's chest, the CPR feedback device 100 monitors the quality of chest compressions in real time, so even non-experts can effectively perform CPR. , the patient's survival rate can be increased by using the defibrillator 200 in parallel.

In addition, according to various embodiments of the present invention, the driving power of the CPR feedback device 100 and the defibrillator 200 is supplied by the same battery 400, so the product has the advantage of miniaturizing the product and improving portability. there is.
