[0001] Vestments in the form of automatic and manual CPR devices [0002]

The present invention is a vest type device to be worn on the front part of the upper part of a subject so that CPR can be performed. The CPR can be performed manually or automatically in CPR It is designed to restore the beating to normal.

In general, cardiopulmonary resuscitation is the maintenance of oxygen supply to tissues in the body through artificial circulation and artificial respiration to prevent irreversible damage to major organs of the body due to cardiac arrest, and ultimately to restore the patient's heart rate, This is a treatment technique that can revive a patient who has stopped. However, the occurrence of cardiac arrest is difficult to predict and 60-80% of cardiac arrest tends to occur outside the home, workplace, street, and other medical facilities. A person who first noticed a heartbeat stop can immediately resume cardiopulmonary resuscitation because the fatal brain damage begins 4 to 6 minutes after the heartbeat stop has occurred. If cardiopulmonary resuscitation is initiated from the onset of cardiac arrest, it may delay the progression of the cardiac arrest to biological mortality, and if cardiopulmonary resuscitation is properly performed by witnesses, the survival rate It is as high as 2 ~ 3 times.

In order to revive a patient with heart palsy, oxygen should be supplied to the tissue by maintaining the breathing and circulating blood as soon as possible after the heartbeat stop has occurred. Cardiopulmonary resuscitation is a therapeutic technique that restores the patient's heartbeat by performing artificial respiration and artificial circulation to maintain oxygen supply to tissues within the body. As such, cardiopulmonary resuscitation has become an important first-aid technique that must be mastered by both professionals and the general public, and CPR has become widespread, and many of the patients suffering from cardiac arrest outside the hospital have survived. Therefore, a person who witnessed a heartbeat-stopping patient informs the emergency medical system of the occurrence of a heartbeat stoppage, and as a first-aid measure for a patient with a heartbeat stoppage, performs artificial respiration and chest compression to maintain the oxygen supply to the body organ Cardiopulmonary resuscitation should be performed. When CPR is performed, the chest compression depth should be more than 5cm and the compression rate should be more than 100 times per minute.

The CPR procedure is to determine if a heart rate arrest patient is first, apnea or abnormal breathing (heart rate stop breathing). Second, call for 119 reporting and automatic defibrillation. Third, to check the pulse, we should look at the artery of the throat and if there is no pulse, press the chest from the outside to artificially circulate blood. Cardiopulmonary resuscitation should be continued without interruption until normal respiration and circulation is restored, and with the assistance of a highly trained medical professional, with cardiopulmonary resuscitation and cardiopulmonary resuscitation in five cycles of 30: 2 ratio.

In such a CPR, chest compressions assist the blood circulation of the patient. In the cardiac arrest state, the blood flow to the important organs including the brain and the heart of the human body is stopped, so that the patient's chest is pressed to maintain a certain degree of blood circulation .

The standardized 2010 CPR Guidelines recommend that chest compressions be performed at a minimum of 100 compressions per minute and compression depths of at least 5 cm (2 inches), but in practice, chest compressions and depths are often lowered , And 8 to 10 ventilations per minute are recommended for patients who have undergone tracheal intubation. However, excessive respiration is often induced, and hyperventilation increases the pressure in the thoracic cavity to lower the coronary perfusion pressure, .

Therefore, an auxiliary device is needed to accurately perform CPR, which is a first aid for restoring normal breathing and circulation when an accident such as a cardiac arrest or a drowning accident occurs.

An apparatus, a method and a system for assisting a rescuer attempting to resuscitate a patient requiring resuscitation are disclosed in, for example, Korean Patent Laid-Open Publication No. 10-2010-0031116 as prior art for solving the above problems The present invention relates to a device configured to be placed in a patient's body in order to provide a command and an indicator for assisting a rescuer in resuscitating a patient and disclosed in Korean Patent Laid-Open Publication No. 10-2012-0062951, A first sensor for measuring a compression acceleration, a second sensor for measuring a second compression acceleration at the lower thoracic part of the patient, and a second sensor for measuring a first compression acceleration and a second compression acceleration based on the measured first compression acceleration and the second compression acceleration, It is possible to monitor the chest compression depth by using two acceleration sensors including a calculation device for estimating the compression depth of the chest, Discloses a system and method for monitoring a patient's chest compaction depth in a CPR that can reduce errors that occur when measuring a chest compression depth using only a sensor. In addition, Korean Patent Registration No. 10-1078911 discloses an apparatus and method for performing a CPR using an audiovisual signal in order to provide a chest compressive assist signal and a ventilation assist signal in visual or auditory sense so that a CPR practitioner can accurately perform chest compressions and ventilation And a resuscitation assist device.

However, the above-mentioned prior arts require a wired or wireless assistance from an external expert when performing cardiopulmonary resuscitation against patients with heart palsy, and the rescuer has no choice but to perform cardiopulmonary resuscitation himself .

In order to solve the above problems, the rescuer can perform cardiopulmonary resuscitation by using the automatic and manual resuscitation apparatus of the present invention, If you are not proficient in cardiopulmonary resuscitation, you can perform CPR with automatic operation, so you can rescue emergency cardiac arrest patients in an emergency.

The present invention is a vest type automatic and manual CP resuscitation apparatus, and is intended to provide a device that can rapidly perform cardiopulmonary resuscitation (CPR) on patients suffering from heart palsy.
