Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a CPR device employing an electromagnet and a stretcher including the CPR device,

Embodiments of the present invention relate to an apparatus for CPR using an electromagnet and a stretcher including the same.

Recently, when CPR is performed in a hospital, it is a tendency to compress or relax the chest by borrowing the power of the machine rather than by the force of the human being.

Currently used devices are not able to cover all patients according to the size of the patient's chest, and the development of the technique of relaxation operation is not improved compared with the compression operation.

In addition, in the case of pediatric infants or adults, the mechanical devices (LUCAS, AUTOPULSE, X-CPR) for current chest compressions can not be applied when the chest size is small. There are many products that can be adjusted up and down in China, but this is also inconvenient to use.

For example, cardiac arrest patients need to adjust their height before giving immediate chest compressions. If the size of the chest is small, or if it is a child or infant, it must be performed with a difference in compression force. It is difficult to do.

Therefore, it is necessary to develop a technique that can adjust the depth of chest compressions that could not be properly controlled by mechanical methods, regardless of the size, age, etc. of the patient.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing an apparatus 100 for CPR using an electromagnet according to an embodiment of the present invention.

Referring to FIG. 1, a CPR apparatus 100 using an electromagnet according to an embodiment of the present invention includes an electromagnet pad unit 110 and a permanent magnet pad unit 120.

The electromagnet pad unit 110 is fixed on the back surface of the patient.

At this time, the electromagnet pad unit 110 is formed in a flat shape so that the patient does not feel inconvenience, so that the electromagnet pad unit 110 can be stably positioned on the back of the patient.

The electromagnet pad unit 110 includes an electromagnet 10 whose polarity is determined according to the direction of a current applied thereto.

The electromagnet 10 may affect the permanent magnets 20 provided in the permanent magnet pad unit 120, which will be described later, by using the magnetism possessed by the current supplied from the outside.

That is, when the electromagnet 10 is magnetized and a magnetic field is formed around the electromagnet 10, the CPR can be performed through the interaction between the electromagnet 10 and the permanent magnet 20 according to the polarity.

The permanent magnet pad portion 120 is positioned on the upper part of the sternum of the patient so as to face the electromagnet pad portion 110.

In other words, the permanent magnet pad unit 120 may be positioned above the sternum of the patient, and may face the electromagnet pad unit 110. Accordingly, the permanent magnet pad unit 120 can receive the influence of the magnetic field formed around the electromagnet pad unit 110 more effectively.

The permanent magnet pad unit 120 includes a permanent magnet 20 for pressing or relaxing the sternum of a patient.

The permanent magnet 20 can move up and down according to the polarity of the electromagnet 10 to press or relax the patient's sternum.

2, when the permanent magnets 20 face each other with different polarities from the electromagnet 10, as the attraction with the electromagnet 10 occurs, the electromagnet 10 is brought close to the electromagnet 10 Direction to compress the sternum.

For example, when the lower polarity of the permanent magnet 20 is N pole and the upper polarity of the electromagnet 10 is the S pole, a pulling force is generated between the permanent magnet 20 and the electromagnet 10, This can be stressed.

3, when the permanent magnet 20 faces the electromagnet 10 with the same polarity, when the repulsive force with the electromagnet 10 is generated, the permanent magnet 20 moves in a direction away from the electromagnet 10 To the sternum.

For example, when both the lower polarity of the permanent magnet 20 and the upper polarity of the electromagnet 10 are N poles, a pushing force is generated between the permanent magnet 20 and the electromagnet 10 to relax the sternum have.

In the present embodiment, the sternal relaxation operation is performed not by simply pressing and releasing the magnet but by moving the permanent magnet 20 upward by the magnetic force between the permanent magnet 20 and the electromagnet 10, Corresponds to the operation.

Thus, if the sternum is compressed with active relaxation, the cerebral blood flow is maintained, and if the sternum is actively relaxed, the coronary blood flow that can benefit the heart can be maintained.

Hereinafter, a process of CPR using the electromagnet pad unit 110 and the permanent magnet pad unit 120 will be described in detail with reference to FIGS. 4 and 5. FIG.

4 is a diagram illustrating an electromagnet pad having an input unit 112, an output unit 114, and a control unit 116 according to an embodiment of the present invention. In this example, the input unit 112 and the output unit 114 are illustrated.

As shown in FIG. 4, the electromagnet pad unit 110 may include an input unit 112, an output unit 114, and a control unit 116.

The input unit 112 may set at least one of the compression depth information of the sternum, the number of pressing times per minute of the sternum, the age-related information of the patient, the compression depth information of the sternum predetermined for each patient's age range, and the power on-off.

To this end, the input unit 112 is implemented in the form of a button or a switch, and may set at least one of the above-described information according to a button pressing operation or a pressing or tilting operation of a switch. In addition, the input unit 112 is implemented in the form of a touch pad or a touch screen, and can directly input at least one of the above-described information by directly inputting information desired by the user.

In this embodiment, as shown in FIG. 5, the input unit 112 is embodied as a button. For reference, the input unit 112 is implemented together with the output unit 114 in a single display device as shown in the figure, but the present invention is not limited thereto and may be implemented in a separate configuration.

Specifically, the first button is a button for setting the power on / off, and the power of the display device can be set. The second and third buttons are buttons for setting the compression depth of the sternum, The fourth and fifth buttons are buttons for setting the number of pressing times per minute of the sternum and can be set so as to reduce or increase the number of pressing times. The sixth button is a button for setting the age range of the patient. The age range of the patient can be set to one of the preset age ranges.

The electromagnet pad unit 110 and the permanent magnet pad unit 120 may each include a sensor 101 for measuring a distance between the electromagnet pad unit 110 and the permanent magnet pad unit 120.

At this time, the pressure depth information of the thorax can be obtained based on the distance between the electromagnet pad portion 110 and the permanent magnet pad portion 120 measured from the sensor 101. [

The output unit 114 may be configured to output the pressure depth information of the sternum, the number of pressing times per minute of the sternum, the age-related information of the patient, At least one of the compression depth information of the sternum can be output.

More specifically, the output unit 114 receives data on the distance between the electromagnet pad unit 110 and the permanent magnet pad unit 120 measured from the sensor 101, and determines the pressure of the sternum The depth information can be output to the screen of the display device.

For reference, the compression depth information of the sternum is information indicating the actual compression depth of the sternum, and the output unit 114 can output a pressing depth that changes as the compression progresses.

Also, before performing the CPR, the age-related information of the patient can be set from the input unit 112. Thus, the output unit 114 outputs the age-related information of the patient and the age- It is possible to output the pressure depth information of the sternum to the screen of the display device.

Thus, when the CPR is performed, the compression depth of the sternum can be adjusted by comparing the compression depth information of the sternum with the compression depth information of the sternum that is preset according to the age range of the patient and the compression depth information of the sternum indicating the compression depth of the actual sternus.

Further, the number of pressing times per minute of the sternum about how many times the sternum is to be pressed from the input unit 112 may be set, and the output unit 114 may output information on the number of pressing times per minute of the sternum And output it to the screen of the display device.

Here, the output unit 114 may further output, in real time, the number of pressing times that changes as the pressing progresses, in addition to the pressing frequency information of the set sternum.

The output unit 114 may further output operation time information or battery remaining amount information in addition to the above-described information. Here, the operation time information is information related to a time when a current is applied to the electromagnet pad unit 110 and the sternum is compressed or relaxed along with the permanent magnet 20, Time information.

The control unit 116 may control at least one of a resistance value applied to the electromagnet 10 and a direction of a current applied to the electromagnet 10 based on the setting through the input unit 112. [

For this purpose, the control unit 116 may be provided in the form of a control circuit in the electromagnet pad unit 110.

Hereinafter, a process of controlling the resistance value applied to the electromagnet 10 by the controller 116 to control the depth of compression of the sternum will be described in detail.

First, when the sternum is pressed, the pushing depth may be set by the input unit 112 based on the sternum compression depth information previously set for each patient's age group, and the control unit 116 controls the electromagnet 10 can be controlled.

For example, suppose the age range of the patient is set to Adult and the compression depth of the sternum corresponding to the adult is 5.5 cm and the compression depth of the sternum is 4.5 cm. At this time, the input unit 112 may preferably be set to deepen the sternal compression depth by a predetermined compression depth by using the third button of FIG.

Accordingly, the control unit 116 can control the resistance value applied to the electromagnet 10 to be lower. This is because the strength of the electromagnet 10 is increased as the resistance value applied to the electromagnet 10 is lowered The depth of compression can become deeper and deeper.

Next, when the sternum is relaxed, the pushing depth can be set by the input unit 112 on the basis of the sternum compression depth information previously set for each patient's age group, and the control unit 116 controls the electromagnet It is possible to control the resistance value applied to the semiconductor device 10.

For example, suppose that the age range of the patient is Child, the compression depth of the sternum corresponding to Child is 3.5 cm, and the compression depth of the sternum is 4.5 cm. At this time, the input unit 112 can be set so that the compression depth of the sternum becomes shallower by a predetermined compression depth by using the second button of FIG.

Accordingly, the control unit 116 can control the resistance value applied to the electromagnet 10 to be higher. This is because the strength of the electromagnet 10 decreases as the resistance value applied to the electromagnet 10 increases The compression depth may become shallower.

As a result, it can be seen that the moving distance of the permanent magnet pad portion 120 in the vertical direction is variable by controlling the intensity of the electromagnet 10 according to the resistance value applied to the electromagnet 10.

For reference, the controller 116 can control the resistance value in a state where the initial value of the resistance value applied to the electromagnet 10 is the maximum.

Accordingly, when the sternal compression starts, sudden increase in the strength of the electromagnet 10 can be prevented, thereby providing an environment for more securely compressing the sternum of the patient.

Meanwhile, the control unit 116 may control the direction of the current applied to the electromagnet 10 to control the number of times the sternum is pressed.

In order for the sternum to be pressed, the polarity of the electromagnet 10 must be continuously changed so as to move the permanent magnet 20 in the vertical direction. The controller 116 controls the current flow so that the polarity of the electromagnet 10 is changed .

In other words, the control unit 116 can control the direction of the current applied to the electromagnet 10 so that the polarity of the electromagnet 10 is changed.

The protruding portion 122a may protrude in a direction in which a trough portion having a predetermined size of the sternum of the patient is located.

That is, since the lower surface of the elastic portion 122 is formed to conform to the sternal shape of the patient, the pressing force applied to the sternum of the patient can be accurately determined.

Referring to FIG. 8, the elastic part 122 may include a display part 122b for guiding the permanent magnet pad part 120 to be positioned above the sternum. 8 corresponds to a top view of the elastic portion 122. As shown in Fig.
