Description

Technical Field [0001] The present invention relates to an automatic defibrillator and an automatic defibrillator,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic defibrillator and a driving method thereof, and more particularly, to an automatic defibrillator and a driving method thereof that perform quick and accurate defibrillation treatment in the event of an emergency.

The automatic defibrillator is a medical device that allows anyone to easily treat a patient in the event of a heart-related emergency in a place where the doctor can not immediately get help, such as in an outdoor activity space. That is, when the user attaches the electrode pad to the patient's heart and operates the automatic defibrillator, the built-in sensor of the automatic defibrillator automatically measures the heart rate, and if the abnormal heart rate is detected, the appropriate defibrillation treatment is performed to restore the heart rate to normal .

In emergency situations related to the heart, delays in treatment can lead to catastrophic conditions such as cardiac arrest, brain damage due to respiratory arrest, and the like. Therefore, the automatic defibrillator should quickly detect abnormal heartbeat and perform defibrillation processing.

However, in the conventional automatic defibrillator, when the power is supplied by the user, the heartbeat of the patient is sensed to determine whether the abnormal heartbeat has occurred, and then electric charge is started. Therefore, the conventional automatic defibrillator has a problem in that it takes a long time until the defibrillation treatment is performed on the patient, and it is difficult to cope with the defibrillation.

Prior Art 1: Korean Patent No. 10-1029511 (Name: Automatic Defibrillator and its Operation Method)

In the drawings, the same reference numerals are used to designate the same or similar components throughout the drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

Hereinafter, an automatic defibrillator according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. 1 is a block diagram for explaining an automatic defibrillator according to an embodiment of the present invention. 2 to 5 are views for explaining the blocking portion of FIG.

1, the automatic defibrillator 100 includes a power button 110, a controller 120, a bio-signal measuring unit 130, a determining unit 140, a charging unit 150, a blocking unit 160, A shock button 170, and an output unit 180.

The power button 110 is provided in the housing 210 to switch on / off the driving power to the automatic defibrillator 100. That is, when the user presses the power button 110, the driving power of the automatic defibrillator 100 is supplied.

The control unit 120 outputs a detection signal to the bio-signal measuring unit 130 for controlling the heartbeat state of the patient when the driving power is supplied by the power button 110. [ At the same time, the control unit 120 transmits to the charging unit 150 a charging signal for controlling the charging of the capacitor for the patient's defibrillation treatment.

The bio-signal measuring unit 130 senses the heartbeat of the patient on the basis of the detection signal from the controller 120. That is, the bio-signal measuring unit 130 receives a detection signal from the sensors attached to the heart of the patient. The bio-signal measuring unit 130 senses the heartbeat of the patient based on the detection signal. The bio-signal measurement unit 130 transmits the sensed heartbeat to the determination unit 140.

The determination unit 140 determines whether a defibrillation operation is performed based on the heartbeat received from the bio-signal measuring unit 130 and the reference value. That is, the determination unit 140 determines that the defibrillation operation is performed if the heartbeat of the patient is below the reference value. The determination unit 140 determines that the defibrillation operation is not performed if the heartbeat of the patient exceeds the reference value. The determination unit 140 transmits the determination result of the defibrillation operation to the blocking unit 160. [

The charging unit 150 charges the power source based on the charging signal from the control unit 120. [ That is, the charging unit 150 includes a capacitor (not shown). When the charging unit 150 receives the charging signal from the controller 120, the charging unit 150 charges the power source to the capacitor. The charging unit 150 transmits the charging status information to the blocking unit 160. [

When the determination unit 140 determines that the defective operation is not performed, the charging unit 150 discharges the charging source power. That is, when the determination unit 140 determines that the defective operation is not performed, the charging unit 150 discharges the power charged in the condenser (not shown).

The blocking unit 160 blocks the shock button 170 based on the determination result of the defibrillation operation received from the determination unit 140 and the charging status information from the charging unit 150. That is, the determination unit 140 determines the defibrillation unit 160 as a defibrillation operation, and when the charging unit 150 receives the charging status information corresponding to the completion of the charging, the shock button 170 is opened. When the determining unit 140 determines that the blocking unit 160 is not operated for defibrillation or receives the corresponding charging state information during charging in the charging unit 150, the shock button 170 is blocked.

At this time. 2, the blocking portion 160 includes a motor (not shown) and a blocking cover 162 installed on the housing 210 to slide left and right (or up and down). The blocking unit 160 drives the motor to change the blocking cover 162 to an open state (i.e., Fig. 3) when the defibrillation operation and the charging completion state are satisfied, so that the shock button 170 installed on the circuit board 220 is exposed . The blocking unit 160 maintains the closed state of the blocking cover 162 to prevent the user from pressing the shock button 170 when the defibrillation unit 160 is in the non-defibrillation or charging state.

4, the blocking portion 160 may include a blocking cover 162 installed in a hinge structure on the housing 210, a locking portion 162 that slides to the left and right (or up and down) to block the rotation of the blocking cover 162, Means 164 and a motor (not shown). When the defibrillation operation and the charging completion state are completed, the blocking section 160 slides the locking means 164 to change the blocking cover 162 to the open state in which the blocking cover 162 can be rotated, and then drives the motor to rotate the blocking cover 162, (I.e., FIG. 5) so that the shock button 170 is exposed to the outside. The blocking unit 160 maintains the closed state of the locking means 164 and the blocking cover 162 to prevent the user from pressing the shock button 170 when the defibrillation unit 160 is in the non-defibrillation or charging state.

The blocking unit 160 may include an electric circuit such as a switching circuit and may block the electrical connection between the charging unit 150 and the output unit 180. For example, the blocking unit 160 electrically connects the charging unit 150 and the output unit 180 when the defibrillation operation and the charging completion state are established. When the user presses the shock button 170, the power of the charging unit 150 is output to the output unit 180). The blocking unit 160 cuts off the electrical connection between the charging unit 150 and the output unit 180 when the defective operation is not being performed or the charging is in progress so that the power of the charging unit 150 can be output to the output unit 150 even if the user presses the shock button 170 180).

The shock button 170 is operated by the user, and when the user presses a button, the charging unit 150 is supplied with power charged to the output unit 180.

When the shock button 170 is pressed and power is supplied from the charger 150, the output unit 180 outputs power and applies an electric shock to the patient. At this time, the output unit 180 is composed of a plurality of devices, and may be operated by receiving power from the charging unit 150 through a power line.

Hereinafter, a method of driving an automatic defibrillator according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. 6 is a flowchart illustrating a method of driving an automatic defibrillator according to an embodiment of the present invention.

When an emergency occurs, the user attaches a sensor for detecting the heartbeat to the patient, and then drives the defibrillator 100 by pressing the power button 110 of the defibrillator 100. [ When the defibrillator 100 is driven (S100; Yes), the controller 120 transmits a detection signal to the bio-signal measuring unit 130 for controlling the heartbeat state of the speaker to be sensed. Accordingly, the bio-signal measuring unit 130 senses the heartbeat of the patient (S200). That is, the bio-signal measuring unit 130 receives a detection signal from the sensors attached to the heart of the patient. The bio-signal measuring unit 130 senses the heartbeat of the patient based on the detection signal. The bio-signal measurement unit 130 transmits the sensed heartbeat to the determination unit 140.

The determination unit 140 determines whether the defibrillator 100 operates based on the heartbeat of the patient sensed by the bio-signal measuring unit 130 (S300). At this time, the determination unit 140 determines whether a defibrillation operation is performed based on the heartbeat received from the bio-signal measuring unit 130 and the reference value. That is, the determination unit 140 determines that the defibrillation operation is performed if the heartbeat of the patient is below the reference value. The determination unit 140 determines that the defibrillation operation is not performed if the heartbeat of the patient exceeds the reference value. The determination unit 140 transmits the determination result of the defibrillation operation to the blocking unit 160. [

The control unit 120 transmits a detection signal to the bio-signal measuring unit 130 and a charging signal for controlling the charging of the capacitor for the patient's defibrillation treatment to the charging unit 150. [ Accordingly, the charger 150 charges the built-in capacitor with power (S400).

The charging unit 150 monitors the power charging state of the capacitor (S500). That is, the charger 150 starts charging according to the control signal of the controller 120, and then monitors the charging state of the capacitor and transmits it to the blocking unit 160.

If the determination unit 140 determines that the defibrillator 100 is in operation and the charging unit 150 is fully charged (S600; YES), the blocking unit 160 releases the blocking of the shock button 170 (S700) . That is, the blocking unit 160 drives the motor to slide the blocking cover 162 provided at the housing 210 of the defibrillator 100 to one side to change the blocking cover 162 to the open state. The blocking unit 160 may also be configured to release the locking means 164 by driving the motor and to rotate the blocking cover 162 upward to slide the blocking cover 162 to open the blocking cover 162. As a result, the shock button 170 is exposed to the outside and the user can operate the shock button 170. The blocking unit 160 may be an electric circuit such as a switching circuit incorporated in place of the blocking cover 162. The blocking unit 160 may electrically connect the charging unit 150 and the output unit 180 when defibrillation operation and charging are completed .

The output unit 180 outputs the power charged in the charger 150 to the patient to perform the defibrillator 100 operation (S800). That is, when the shock button 170 is changed to the open state by the blocking unit 160, the user controls the operation of the defibrillator 100 by pressing the shock button 170 exposed to the outside. Accordingly, the charging unit 150 supplies the charged power to the output unit 180. The output unit 180 outputs power supplied from the charging unit 150 to apply an electric shock to the patient.

Meanwhile, when the determining unit 140 determines that the defibrillator 100 is not operated, the charging unit 150 discharges the charged power (S850). In other words,

At the same time, the blocking unit 160 maintains the blocking state of the shock button 170 (S900). That is, when the determining unit 140 determines that the blocking unit 160 is not deflected or receives the charging state information during charging in the charging unit 150, the blocking state of the blocking cover 162 is maintained, The shock button 170 is cut off so that the button 170 can not be pressed. Of course, the blocking unit 160 may be formed of an electric circuit such as a built-in switching circuit in place of the blocking cover 162 to block the electrical connection between the charging unit 150 and the output unit 180. Thus, even if the user presses the shock button 170, power is not applied to the output unit 180, thereby preventing the patient from being subjected to electric shock.

As described above, the automatic defibrillator and the driving method thereof perform the defibrillation treatment within approximately 5 seconds by performing the charging at the same time as the analysis of the heartbeat, so that the defibrillator can quickly cope with the emergency related to the patient's heart.

In addition, since the automatic defibrillator and the driving method thereof can drive the shock button only when the heart of the patient is abnormal, it is possible to safely perform the defibrillation treatment even for an infrequent user of the automatic defibrillator.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but many variations and modifications may be made without departing from the scope of the present invention. It will be understood that the invention may be practiced.
