Description

[Technical Field]

[0001] The following disclosure relates to a portable cardiopulmonary resuscitation device and applicable components therefor. [Background technology]

[0002] CPR is an essential first aid measure when the heart stops functioning. If not performed promptly, brain damage begins after four minutes and serious damage to other vital organs occurs. Survival rates drop sharply after 10 minutes. While survival rates typically decrease by 7-10% for every minute that defibrillation is delayed, it is known that CPR reduces survival rates by 2.5-5%. Proper CPR significantly improves survival rates. However, even trained personnel often become confused when faced with CPR and are unable to perform it properly.

[0003] In accordance with the latest CPR guidelines, which require maintaining a rate of 100 or more compressions per minute at a depth of at least 5 cm and maintaining adequate cardiac output through sufficient relaxation between compressions, the system is required to explore optimal CPR techniques and develop a system that can provide continuous chest compressions without fatigue.

[0004] Furthermore, with existing chest compression devices, the position of the chest compressor is fixed in the initial installation position, making it difficult to respond quickly to incorrect placement when the patient is unconscious, which can significantly reduce the chances of the patient being resuscitated.

[0005] That is, the chest compression position of the chest compressor is fixed at a specific position on the patient's chest the moment the device is first installed. Therefore, even if the user realizes that the device has been installed incorrectly, they must either move the entire device installed on the patient to correct the position, or, depending on the situation, separate and reattach a portion of the device. In this case, the patient often misses the golden time, which can lead to fatal problems that make resuscitation difficult, and ultimately leads to CPR being performed even though the user knows that the device has been installed in the wrong position.

[0006] Therefore, there is a need to improve the existing cardiopulmonary resuscitation devices so that they can provide appropriate effects to solve these problems. [Prior art documents] [Patent documents]

[0055] FIG. 1 is a schematic diagram showing the structure of a position moving unit of a portable cardiopulmonary resuscitation device including a position moving unit according to one embodiment.

[0056] FIG. 2 is a schematic diagram showing an internal connection structure of a portable cardiopulmonary resuscitation device including a position moving unit according to an embodiment.

[0057] FIG. 3 is a perspective view showing a schematic structure of the distal end of the compression module 10 according to one embodiment.

[0058] According to one embodiment, a portable cardiopulmonary resuscitation device including a position moving unit includes a main body and a compression module connected to the main body for compressing a patient's chest in a first direction toward a lower side of the main body. The main body may include an opening formed therethrough in the first direction, the compression module may be disposed in the opening, and the compression module may be connected to a position moving unit for moving a compression position of the patient's chest with two degrees of freedom on a plane perpendicular to the first direction.

[0059] In an embodiment, the position moving part may include a position moving handle extending in a first direction toward an upper side of the main body.

[0060] The position movement handle is connected to the compression module and can be used as a means for moving the compression module. The position movement handle can be operated manually or automatically.

[0061] In one embodiment, the position movement handle may include a brake release button formed on one side thereof, and when the brake release button is pressed, the position movement handle may be moved on a plane perpendicular to a first direction, and when the position movement handle is moved, the compression module may also move together on the same plane.

[0062] The position moving handle is braked when the cardiopulmonary resuscitation device is not in use, and can be moved by pressing the release button.

[0063] In one embodiment, the brake is electronic and further includes a brake controller electrically connected to the brake release button, and the position movement handle may be manually moved by a user applying an external force.

[0064] In one embodiment, when the brake release button is pressed, the distal end position of the compression module may move by several tens of millimeters in a first direction toward the upper side of the main body.

[0065] When the brake release button is pressed in this manner, the compression module that has been in close contact with the chest moves across a space, allowing the user to easily move their position on a flat surface.

[0066] In one embodiment, the brake is mechanically motorized and the movement of the positioning handle may be electronically movable.

[0067] In this case, the electronic movement may be controlled by inputting the movement distance using a digital button method, as is the method used in electronic surgical devices, or may be controlled by a computer or an external remote control.

[0068] In one embodiment, the position moving unit may include an upper plate of a chest compressor, a chest compression motor located at the center of the upper plate, a first brake gear and a plurality of first link groups located on one side of the chest compression motor on the upper plate; and a second brake gear and a plurality of second link groups located on the other side of the chest compression motor on the upper plate.

[0069] The first link group may be configured to include a 1-1 link and a 1-2 link, and in this case, the 1-2 link may be fixed to a position of the motor housing, and one side of the 1-1 link may be connected to the 1-2 link by a joint and the other side may be connected to the first brake gear.

[0070] The second link group may also be configured to include a 2-1 link and a 2-2 link, and in this case, the 2-2 link may be connected to the motor housing by a bearing, and the 2-1 link may be connected to the 2-2 link by a joint on one side and to the second brake gear on the other side.

[0071] In one embodiment, the device may further include a reinforcing plate located on the top plate between the position moving handle, and the reinforcing plate may prevent impact on components located on the top plate from an external force applied through the handle.

[0072] The reinforcing plate serves to prevent the risk of damage to the links and joints included in the position moving part due to loads being applied in the vertical or horizontal directions when a user grips the handle and pushes it downward, when applying force to the left or right while braking, or when the product is dropped onto the handle.

[0073] In one embodiment, the position moving section may include a five-link structure capable of two degrees of freedom of movement in a plane.

[0074] As described above, Fig. 2 shows a five-link structure that allows the position adjustment handle to move with two degrees of freedom on a plane perpendicular to the first direction according to one embodiment of the present invention. However, the technical concept of the present invention includes any structure that allows the position adjustment handle and compression module to move on a plane, and is not necessarily limited to the structure shown in Fig. 2 as described above.

[0075] According to one embodiment, a portable cardiopulmonary resuscitation device including a position moving unit includes a main body and a compression module connected to the main body for applying pressure to a patient's chest in a first direction toward a lower side of the main body. The main body may include an opening formed therethrough in the first direction, the compression module may be disposed in the opening, and a detachable column-shaped compression extender may be provided at a lower end of the compression module.

[0076] The compression module may be configured to penetrate the main body, so that the end of the compression module can be moved to a position suitable for chest compression for cardiopulmonary resuscitation using a handle located at the top.

[0077] In one embodiment, the compression module may include an extender fastening hook protruding outward from a lower end thereof, and the compression extender may include a stepped portion protruding inward from an upper end thereof, such that the hook and the stepped portion can be hooked together to allow the compression extender to be attached to the end of the compression module.

[0078] The compression extender may be connected to the compression module through various structures. In one example, the compression module has a hook and the compression extension has a stepped portion, allowing for quick fastening in an emergency.

[0079] In one embodiment, the compression module may have a handle at its lower end for attaching and detaching the compression extender, and when a user applies an external force to the handle, the hooks are pushed inward, and the compression module and the compression extender are separated.

[0080] The device may be designed so that a user can push the left and right sides of the handle to push the hooks of the compression module inward and separate the stepped portions of the compression extender. This structure is simple and intuitive, allowing the compression extender to be quickly attached and detached in the most urgent situations. This is particularly useful when cardiopulmonary resuscitation must be performed on multiple patients or when the patient's chest height is different from the expected height, making it necessary to reattach a compression extender that has already been attached.

[0081] The compression module may be designed to be detachable when the user applies a slight external force, such as by turning or pushing a handle.

[0082] FIG. 4 is a schematic diagram showing a portable cardiopulmonary resuscitation device equipped with a compression extender according to an embodiment, in a state where the compression extender is not attached (left view), a state where a short compression extender is attached (middle view), and a state where a high compression extender is attached (right view).

[0083] As shown in FIG. 4, the compression extender can be fastened and attached at any height depending on the patient's body shape, or chest compression can be performed without the compression extender attached depending on the situation.

[0084] In one embodiment, the compression module may include a laser emitter located at the center of the distal end, and the compression extender may include a through-hole in the center, so that the laser emitted from the laser emitter can be transmitted through the compression extender.

[0085] The laser light emitting unit 13 may include a laser pointer lens.

[0086] In one embodiment, the laser light emitting unit may be used to visually indicate on the patient's chest the position to be compressed using the cardiopulmonary resuscitation device.

[0087] The position of the patient's chest being compressed is displayed on the patient's chest through the laser generated by the laser emitting unit, allowing the user to effectively compress the position of the patient's chest.

[0088] The compression extender may also be designed to include a laser pointer lens (not shown) near the central opening, which can effectively indicate the compression position on the patient's chest even when the compression extender is worn.

[0089] In one embodiment, the compression extender may be replaceable with a plurality of different compression extenders of different heights depending on the patient's body type and situation.

[0090] The compression extender may be provided in at least two types depending on the situation, and may be transported to the site and selected and fitted according to the patient's body shape on site.

[0091] In one embodiment, the compression extender may have a height of 30mm to 130mm.

[0092] This is an optimal value designed to be versatile in all conditions and environments, based on statistical data measuring the chest width and height of normal people by age after setting the appropriate chest compression depth according to the AHA guidelines.

[0093] The inventors have compiled data measuring the width and height of the chest through various medical data, and derived the length of the extender depending on the usable chest height and compression depth.

[0094] FIG. 5 is a diagram illustrating a state in which a portable cardiopulmonary resuscitation device according to one embodiment is used.

[0095] Referring to Fig. 5, a portable cardiopulmonary resuscitation device 1 according to one embodiment can be used to perform cardiopulmonary resuscitation (CPR) on a patient P. The portable cardiopulmonary resuscitation device 1 according to one embodiment can change its state depending on whether it is in use or not, so as to have high portability. For example, the portable cardiopulmonary resuscitation device 1 can be used in a use state as shown in Fig. 5 (e.g., the first state in Fig. 6) during use on a patient P, and can change its state to a portable state as shown in Fig. 8 during storage or transportation.

[0096] In one embodiment, in the usage state shown in FIG. 5 , the portable cardiopulmonary resuscitation apparatus 1 can repeatedly perform chest compressions on a patient P lying on the ground at a set depth and frequency. In one embodiment, the portable cardiopulmonary resuscitation apparatus 1 can adjust the chest compression position on the patient P to an optimal position depending on the condition of the patient P (e.g., the body size of the patient P, the position of the heart of the individual patient P, etc.). In one embodiment, the portable cardiopulmonary resuscitation apparatus 1 can change its state during storage or transportation so that it can be easily held by a user (e.g., a user using the cardiopulmonary resuscitation apparatus 1). For example, the portable cardiopulmonary resuscitation apparatus 1 has high portability and ease of use, and can be used to perform quick and accurate cardiopulmonary resuscitation on a patient P in an emergency situation.

[0097] Figure 6 is a perspective view showing a first state of a portable cardiopulmonary resuscitation device 1 according to one embodiment, Figure 7 is a perspective view showing the process of separating the connecting frame in a portable cardiopulmonary resuscitation device 1 according to one embodiment, and Figure 8 is a perspective view showing a second state of a portable cardiopulmonary resuscitation device 1 according to one embodiment.

[0098] 6 to 8, the portable cardiopulmonary resuscitation device 1 according to one embodiment may include a main body 100, a compression module 140, a first connecting frame 110, a second connecting frame 120, and a fixing frame .

[0099] In one embodiment, the main body 100 may be embodied in various forms and may include an input interface (not shown) for receiving input of a user's command. In one embodiment, various components (e.g., compression module 140, battery 170, camera 160, etc.) for performing cardiopulmonary resuscitation on the patient P may be disposed in the main body 100. In one embodiment, the main body 100 may include a display unit (not shown) disposed on a surface thereof for displaying various information including operation information of the portable cardiopulmonary resuscitation device 1, sensing information on the patient P, etc. For example, the display unit may be for displaying visual, audible, etc. information and may include a display or a speaker, etc.

[0100] In one embodiment, the main body 100 may be located at a position spaced apart from the ground based on a first state as shown in Fig. 6. In this case, when the portable cardiopulmonary resuscitation apparatus 1 is used on a patient P as shown in Fig. 5, the main body 100 may be located above the chest of the patient P. In one embodiment, the main body 100 may be located on the ground based on a second state as shown in Fig. 8. For example, the position of the main body 100 within the portable cardiopulmonary resuscitation apparatus 1 may be changed relative to the state of the portable cardiopulmonary resuscitation apparatus 1.

[0101] In one embodiment, the main body 100 may have a shape that extends in one direction (e.g., the X-axis direction). In this case, a first connection frame 110 and a second connection frame 120 may be connected to both sides of the main body 100. The first connection frame 110 and the second connection frame 120 may be connected to the main body 100 so as to be opposite each other. The main body 100 may include a first portion 102 (e.g., a portion of the main body 100 facing the +X direction) to which the first connection frame 110 is connected, and a second portion 101 (e.g., a portion of the main body 100 facing the -X direction) opposite the first portion 102 and to which the second connection frame 120 is connected.

[0102] In one embodiment, the main body 100 may include an opening formed through it in a first direction (e.g., Z-axis direction). The opening may be formed at a central portion based on the extension direction of the main body 100. When the main body 100 is in the first state, the opening may be formed at a portion overlapping with the fixing frame 130 when viewed from the first direction. In one embodiment, the compression module 140 may be disposed in the opening, and other components of the compression module 140 except for some components (e.g., compression member, input handle 1413, etc.) may be covered with other components to prevent them from being exposed to the outside. A description thereof will be omitted.

[0103] In one embodiment, the compression module 140 may be coupled to the main body 100. For example, the compression module 140 may be coupled to the main body 100 so as to be positioned in the opening. In one embodiment, the compression module 140 may apply pressure to the chest of the patient P in a first direction toward the underside of the main body 100, for example, toward the fixed frame 130. The compression module 140 will be described in detail below.

[0104] In one embodiment, the first connection frame 110 and the second connection frame 120 may be rotatably connected to the main body 100, respectively.

[0105] In one embodiment, the first connection frame 110 is connected to the first portion 102 of the main body 100 and can rotate relative to the main body 100 around a first rotation axis A1. In one embodiment, the first connection frame 110 may extend from the first portion 102 of the main body 100 in a first length direction. A first connection portion 111 may be formed at an extended end of the first connection frame 110 (e.g., an end of the first connection frame 110 facing the -Z direction in FIG. 6 ). In one embodiment, the first connection frame 110 may be connected to the fixing frame 130 through the first connection portion 111. For example, a connection rod may be formed in the first connection portion 111, which is inserted and fastened to a first insertion portion of the fixing frame 130, which will be described later.

[0106] In one embodiment, the second connection frame 120 is connected to the second portion 101 of the main body 100 and can rotate relative to the main body 100 around the second rotation axis A2. In one embodiment, the second connection frame 120 may extend from the second portion 101 of the main body 100 in a second length direction. A second connection portion 121 may be formed at an extended end of the second connection frame 120 (e.g., an end of the second connection frame 120 facing the -Z direction in FIG. 6 ). In one embodiment, the second connection frame 120 may be connected to the fixing frame 130 via the second connection portion 121. For example, a connection rod may be formed in the second connection portion 121, which is inserted and fastened to a second insertion portion of the fixing frame 130, which will be described later.

[0107] In one embodiment, the first connecting frame 110 and the second connecting frame 120 can change the state of the portable cardiopulmonary resuscitation device 1 between a first state and a second state by rotating relative to the main body 100. In one embodiment, the first connecting frame 110 and the second connecting frame 120 can rotate relative to the main body 100 to be in the first state (e.g., FIG. 6) in which the first connecting portion 111 and the second connecting portion 121 are located below the main body 100 and can be coupled to the fixing frame 130. In one embodiment, the first connecting frame 110 and the second connecting frame 120 can rotate relative to the main body 100 to be in the second state (e.g., FIG. 8) in which the first connecting portion 111 and the second connecting portion 121 are located above the main body 100.

[0108] In one embodiment, the first connecting frame 110 and the second connecting frame 120 may be connected to the fixing frame 130 in the first state of the portable cardiopulmonary resuscitation apparatus 1. In this case, the main body 100, the first connecting frame 110, the second connecting frame 120, and the fixing frame 130 may form a seating space in which the body of the patient P can be positioned. For example, the portable cardiopulmonary resuscitation apparatus 1 may surround the body of the patient P with the seating space at the center. In one embodiment, before the state of the portable cardiopulmonary resuscitation apparatus 1 is converted from the first state to the second state, the connection state of the fixing frame 130 to the first connecting frame 110 and the second connecting frame 120 may be released, as shown in FIG. 7 . In one embodiment, the first connecting frame 110 and the second connecting frame 120 may be rotated relative to the main body 100 to convert the portable cardiopulmonary resuscitation apparatus 1 to the second state. In this case, the first connecting frame 110 and the second connecting frame 120 can serve as carrying handles to be gripped by the user when the portable cardiopulmonary resuscitation device 1 is in the second state. For example, gripping grooves that can be gripped by the user's hands may be formed at the ends of the first connecting frame 110 and the second connecting frame 120.

[0109] In one embodiment, the distance between the first connection frame 110 and the second connection frame 120 may vary depending on the rotational state of the portable cardiopulmonary resuscitation apparatus 1 relative to the main body 100. In one embodiment, the first rotation axis A1 and the second rotation axis A2 may form an intersection below the main body 100. For example, the first rotation axis A1, about which the first connection frame 110 rotates relative to the main body 100, may be inclined toward the ground (e.g., the XY plane). In this case, the first rotation axis A1 may be inclined upward from the main body 100 toward the first connection frame 110 relative to the ground. The second rotation axis A2, about which the second connection frame 120 rotates relative to the main body 100, may be inclined toward the ground. In this case, the second rotation axis A2 may be inclined upward from the main body 100 toward the second connection frame 120 relative to the ground. In this case, the first connection frame 110 and the second connection frame 120 may be closer to each other when the portable cardiopulmonary resuscitation apparatus 1 is in the second state than when it is in the first state. In one embodiment, the first connection frame 110 and the second connection frame 120 may have a streamlined curved shape along their respective length directions. For example, the first connection frame 110 and the second connection frame 120 may be formed such that the distance between them increases as they move away from the main body 100, based on the first state shown in FIG. 6, and then approach each other at the first connection portion 111 and the second connection portion 121. In this case, the first connection portion 111 and the second connection portion 121 may form a minimum distance in the second state of the portable cardiopulmonary resuscitation apparatus 1. In another embodiment, the first rotation axis A1 and the second rotation axis A2 may be coincident with or parallel to each other. In this case, the first connection frame 110 and the second connection frame 120 may have a curved shape along their length directions so that the portable cardiopulmonary resuscitation apparatus 1 can be easily gripped by a user in the second state.

[0110] In one embodiment, the fixing frame 130 may be detachably coupled to the first connecting frame 110 and the second connecting frame 120. For example, in the first state of the portable cardiopulmonary resuscitation device 1, the fixing frame 130 is placed on the ground, and both ends are fastened to the first connecting portion 111 and the second connecting portion 121, respectively, to support the back of the patient P positioned in the resting space. When fastened to the first connecting portion 111 and the second connecting portion 121, the fixing frame 130 may function as a support base that allows the first connecting frame 110, the second connecting frame 120, and the main body 100 to stand on the ground. A support portion 131 for comfortably supporting the patient P's body may be formed on a surface of the fixing frame 130, for example, on a portion that comes into contact with the patient P's body. The support portion may be formed of a material such as a compressible material, sponge, or rubber. In one embodiment, the fixing frame 130 can be separated from the first connecting frame 110 and the second connecting frame 120 as shown in FIG. 7 during the process of converting the portable cardiopulmonary resuscitation apparatus 1 from the first state to the second state.

[0111] In this way, when the fixing frame 130 is detachably fastened to the first connecting frame 110 and the second connecting frame 120, cardiopulmonary resuscitation on an unconscious patient P can be more easily performed. For example, when the portable cardiopulmonary resuscitation device 1 is used on an unconscious patient P, the fixing frame 130 is first placed on the ground, and the patient P is then positioned on the upper surface, e.g., the support portion, of the fixing frame 130. The first connecting frame 110 and the second connecting frame 120 are then coupled to the fixing frame 130 so that the patient P can be positioned within the seating space. In one embodiment, the fixing frame 130 overlaps with the compression module 140 for chest compression of the patient P when viewed from a first direction (e.g., the Z-axis direction), and therefore the fixing frame 130 can also function as an index for locating the chest region of the patient P for chest compression.

[0112] For example, as shown in Figures 6 to 8, the state of the portable cardiopulmonary resuscitation device 1 can be quickly and easily changed through the rotation of the first connecting frame 110 and the second connecting frame 120 relative to the main body 100 and the fastening of the fixing frame 130 relative to the first connecting frame 110 and the second connecting frame 120.

[0113] FIG. 9 is a diagram showing a compression extender, a battery, and a measuring unit of a portable cardiopulmonary resuscitation device 1 according to an embodiment, and FIG. 10 is a block diagram of the portable cardiopulmonary resuscitation device according to an embodiment.

[0114] 9 and 10 , the portable cardiopulmonary resuscitation device 1 according to one embodiment may further include a compression extender 105, a battery 170, a measuring unit 150, and a processor 190 disposed inside the main body 100. In one embodiment, the compression extender 105, the battery 170, and the measuring unit 150 may be hidden through a cover and selectively exposed to the outside as needed. For example, the measuring unit 150 may be exposed to the outside to detect the condition of the patient P when the portable cardiopulmonary resuscitation device 1 is used. In one embodiment, the processor 190 may be provided inside the main body 100.

[0115] However, the positions of the components shown in the drawings are merely examples and are not limiting.

[0116] In one embodiment, the portable cardiopulmonary resuscitation device 1 may further include a camera C. In one embodiment, the camera C may capture an image of a chest compressor 141 (described later) compressing the chest of a patient P positioned in the resting space. In one embodiment, the image captured by the camera C may be displayed on a display or analyzed by the processor 190. In one embodiment, the camera C may capture an image of the chest of the patient P, thereby providing the processor 190 with information for searching for a chest compression position suitable for the patient P. In one embodiment, the camera C may be an external device, rather than being provided in the portable cardiopulmonary resuscitation device 1.

[0117] In one embodiment, the measurement unit 150 may sense information regarding the chest compression operation performed on the patient P. For example, the measurement unit 150 may include one or more sensors, such as a pressure sensor, a torque sensor, or a load cell, for measuring in real time the force or torque generated when the chest compressor 141, which will be described later, contacts the patient P. In one embodiment, the measurement unit 150 may include one or more sensors for detecting biological information of the patient P. For example, the measurement unit 150 may include one or more sensors for measuring various biological signals of the patient P, such as information on the patient P's cardiac output, blood pressure, electrocardiogram, blood oxygen saturation, etc.

[0118] In one embodiment, the processor 190 may control the operation of the portable cardiopulmonary resuscitation device 1. In one embodiment, the processor 190 may search for optimal compression conditions for the patient P based on information detected through the camera C, the measurement unit 150, etc. For example, the processor 190 may detect an initial chest compression point suitable for the patient P through the camera C and adjust the position of the compression module 140 so that the chest compressor 141 can compress the detected initial chest compression point. In one embodiment, the processor 190 may detect and provide conditions that can provide optimal chest compressions for the patient P based on information detected through the measurement unit 150, such as the cardiac output of the patient P. The processor 190 may determine compression conditions, compression positions, etc. of the chest compressor 141 for the patient P based on the detected information. Setting of the chest compression positions and operation conditions by the processor 190 may be performed according to a preset algorithm, the description of which will be omitted.

[0119] In one embodiment, the battery 170 can provide power for the operation of the portable cardiopulmonary resuscitation device 1. In one embodiment, the battery 170 can be attached to or detached from the main body 100.

[0120] FIG. 11 is a perspective view of a portable cardiopulmonary resuscitation device 1 according to one embodiment, and FIGS. 12 and 13 are views of a compression module 140 according to one embodiment from different directions.

[0121] The compression module shown in FIGS. 11 to 13 is one example, and the end may be designed so that a compression extension can be attached as in the structure shown in FIG.

[0122] 11, 12, and 13, the portable cardiopulmonary resuscitation device 1 can compress a body part of a patient P, such as the chest of the patient P, disposed on the fixed frame 130 through the compression module 140. In one embodiment, the compression module 140 can be disposed within an opening in the main body 100.

[0123] In one embodiment, the compression module 140 can operate when the portable cardiopulmonary resuscitation device 1 is in a first state (e.g., the first state in FIG. 6 ). In one embodiment, the compression module 140 can compress the chest of the patient P in a first direction (e.g., the −Z direction in FIG. 6 ) facing downwards of the main body 100. The compression module 140 can change the compression position for the patient P placed in a fixed position, for example, on the fixed frame 130.

[0124] In one embodiment, the compression module 140 may include a chest compressor 141 that operates to compress the body of the patient P, an input handle 1413, and one or more position adjustment portions and stops 144 for adjusting the position of the chest compressor 141 relative to the main body 100.

[0125] In one embodiment, the chest compressor 141 may be connected to the main body 100 so that its position is adjustable. When the portable cardiopulmonary resuscitation device 1 is in the first state, the horizontal position of the chest compressor 141 may be adjusted on a plane perpendicular to a first direction (e.g., the XY plane in FIG. 6 ) relative to the main body 100. Hereinafter, for ease of explanation, the position of the chest compressor 141 on the plane perpendicular to the first direction will be referred to as the horizontal position. As the horizontal position of the chest compressor 141 relative to the main body 100 changes, the part of the patient P at which the chest compressor 141 compresses may be changed. In one embodiment, the horizontal position of the chest compressor 141 relative to the main body 100 may be adjusted to correspond to the optimal compression part for the patient P detected by the processor 190. In one embodiment, the chest compressor 141 may include a compression member 1411, an actuator 1412, an encoder 1414, and a switch 1415.

[0126] The compression member 1411 may be located at a lower end of the chest compressor 141. The position of the compression member 1411 in a first direction relative to the main body 100 may be changed by the operation of the chest compressor 141. For example, the compression member 1411 may reciprocate in the first direction and the opposite direction to repeatedly compress the chest of the patient P by the operation of the chest compressor 141. In one embodiment, the compression member 1411 may contact the chest of the patient P through its lower end. In another example, a separate contact member for contacting the chest of the patient P may be replaceably connected to the lower end of the compression member 1411.

[0127] In one embodiment, the compression member 1411 can reciprocate along a first direction by operation of the actuator 1412. The actuator 1412 can operate so that the compression member 1411 can compress the chest of the patient P at a set pressure and at a set period set by a signal from the processor 190. In one embodiment, the chest compressor 141 can include an encoder 1414 for detecting a signal generated by operation of the actuator 1412 and a switch 1415 for controlling the operation of the actuator 1412.

[0128] In one embodiment, the input handle 1413 may be coupled to the upper end of the chest compressor 141. The input handle 1413 may, for example, protrude from an upper side of the main body 100. In one embodiment, the input handle 1413 is gripped by a user and receives a force from the user to move horizontally together with the chest compressor 141. In one embodiment, the input handle 1413 may receive an input of a position adjustment signal for the chest compressor 141 from the user. The position adjustment signal may be a force applied to the handle by the user. For example, when a first signal is input by the user (e.g., a signal generated by pushing or pulling the input handle 1413), the input handle 1413 may activate / release a stopper 144 (described below) so that the horizontal position of the chest compressor 141 is adjusted by the position adjustment unit or the horizontal position of the chest compressor 141 is fixed. In one embodiment, when a position adjustment signal is input by the user (for example, a signal by horizontally moving the input handle 1413), the position adjustment unit operates in response to the signal from the input handle 1413, thereby adjusting the horizontal position of the chest compressor 141 relative to the main body 100.

[0129] In one embodiment, one or more position adjusters are coupled to the chest compressor 141 and are operable to change the horizontal position of the chest compressor 141 relative to the main body 100 .

[0130] In one embodiment, the position adjustment unit may include a first position adjustment unit 142 and a second position adjustment unit 143. However, only one of the first position adjustment unit 142 and the second position adjustment unit 143 may be provided.

[0131] In one embodiment, the first position adjustment unit 142 can adjust the horizontal position of the chest compressor 141 relative to a first fixed axis B1 that is fixed in a plane perpendicular to the first direction. In one embodiment, the first fixed axis B1 can be aligned with the first direction (i.e., parallel to the Z-axis). In one embodiment, the first position adjustment unit 142 can be rotatably coupled to the first fixed axis B1 and the chest compressor 141. The first position adjustment unit 142 can adjust the distance between the first fixed axis B1 and the chest compressor 141. In this case, the horizontal position of the chest compressor 141 can be changed by changing the angle and distance of the chest compressor 141 relative to the first fixed axis B1 through operation of the first position adjustment unit 142.

[0132] In one embodiment, the first position adjustment unit 142 may include a first rotating link 1421 rotatably connected to a first fixed shaft B1, and a first connecting link 1422 rotatably connected to the first rotating link 1421 and the chest compressor 141. In one embodiment, the first rotating link 1421 may rotate around the first fixed shaft B1. For example, the first rotating link 1421 may be connected to a gear disposed on the first fixed shaft B1 and may rotate around the first fixed shaft B1 through the operation of the gear. In one embodiment, both ends of the first connecting link 1422 may be rotatably connected to the first rotating link 1421 and a first point on the chest compressor 141, respectively. The first connecting link 1422 is located on the first rotating link 1421 and may rotate around a first connecting axis C1 parallel to the first fixed axis B1. The position of the first connecting axis C1 may be changed by the first rotating link 1421 rotating around the first fixed axis B1. The first connecting link 1422 is located at a first point of the chest compressor 141 and can rotate about a first central axis D1 aligned with the first connecting axis C1. With this structure, the horizontal position of the chest compressor 141 can be adjusted without restriction within the main body 100 by rotating the first rotating link 1421 relative to the first fixed axis B1 and by rotating the first connecting link 1422 relative to the first rotating link 1421.

[0133] In one embodiment, the second position adjustment unit 143 can adjust the horizontal position of the chest compressor 141 relative to a second fixed axis B2 that is fixed in a plane perpendicular to the first direction. In one embodiment, the second fixed axis B2 can be aligned with the first direction (i.e., parallel to the Z-axis). In one embodiment, the second position adjustment unit 143 can be rotatably coupled to the second fixed axis B2 and the chest compressor 141. The second position adjustment unit 143 can adjust the distance between the first fixed axis B1 and the chest compressor 141. Therefore, the horizontal position of the chest compressor 141 can be changed as the angle and distance of the chest compressor 141 relative to the second fixed axis B2 change.

[0134] In one embodiment, the second position adjustment unit 143 may include a second rotation link 1431 rotatably connected to the second fixed shaft B2, and a second connecting link 1432 rotatably connected to the second rotation link 1431 and the chest compressor 141. In one embodiment, the second rotation link 1431 may rotate around the second fixed shaft B2. For example, the second rotation link 1431 may be connected to a gear disposed on the second fixed shaft B2 and may rotate around the second fixed shaft B2 through the operation of the gear. In one embodiment, both ends of the second connecting link 1432 may be rotatably connected to the second rotation link 1431 and a second point on the chest compressor 141, respectively. The second connecting link 1432 is located on the second rotation link 1431 and may rotate around a second connecting shaft C2 parallel to the second fixed shaft B2. The position of the second connecting shaft C2 may be changed by the second rotation link 1431 rotating around the second fixed shaft B2. The second connecting link 1432 is located at a second point of the chest compressor 141 and can rotate about a second central axis D2 aligned with the second connecting axis C2. With this structure, the horizontal position of the chest compressor 141 can be adjusted without restriction within the main body 100 by rotating the second rotating link 1431 relative to the second fixed axis B2 and by rotating the second connecting link 1432 relative to the second rotating link 1431.

[0135] In one embodiment, the first position adjustment unit 142 and the second position adjustment unit 143 support the chest compressor 141 from both sides, thereby enabling more stable adjustment of the horizontal position of the chest compressor 141. In one embodiment, at least one of the first position adjustment unit 142 and the second position adjustment unit 143 is connected to a second actuator (not shown) and can be operated by power provided by the second actuator.

[0136] For example, the first position adjustment unit 142 may change the horizontal position of the chest compressor 141 by operation of the second actuator. In this case, the second position adjustment unit 143 may support the chest compressor 141 and simultaneously operate in response to a change in the position of the chest compressor 141 caused by operation of the first position adjustment unit 142. However, this is merely an example, and the first position adjustment unit 142 and the second position adjustment unit 143 may be operated by a force applied by the user through the input handle 1413. The following description will focus on a case where the first position adjustment unit 142 and the second position adjustment unit 143 are operated by a force applied by the user.

[0137] In one embodiment, the stopper 144 may be connected to at least one of the first position adjustment unit 142 and the second position adjustment unit 143. For example, a pair of stoppers 144 may be connected to the first position adjustment unit 142 and the second position adjustment unit 143, respectively. The stopper 144 may prevent the horizontal position of the chest compressor 141 from being arbitrarily changed by selectively limiting the operation of the first position adjustment unit 142 and the second position adjustment unit 143. In one embodiment, the stopper 144 may be mechanically operated by manual operation, but may alternatively be automatically operated, for example, by an operation signal (e.g., an operation signal from the processor 190 or a user), to limit the operation of the position adjustment unit.

[0138] According to another embodiment, a method for using a portable cardiopulmonary resuscitation device including a position movement unit includes a main body and a compression module connected to the main body for compressing the patient's chest in a first direction toward a lower side of the main body, and the method may include the steps of: putting the portable cardiopulmonary resuscitation device on the patient; pressing a brake release button; gripping a position movement handle to move the compression module to an appropriate chest compression position; releasing the brake release button; and compressing the chest using the compression module.

[0139] In one embodiment, moving the compression module may include moving the compression module with two degrees of freedom in a plane perpendicular to the first direction.

[0140] In one embodiment, the portable cardiopulmonary resuscitation device including the position moving unit may be a portable cardiopulmonary resuscitation device according to one embodiment of the present invention.

[0141] According to another embodiment, a method for using a portable cardiopulmonary resuscitation device including a position moving unit includes a main body and a compression module connected to the main body for compressing a patient's chest in a first direction toward a lower side of the main body, and the method may include the steps of: determining a patient's body type; selecting a compression extender according to the patient's body type and condition; attaching the compression extender to the compression module; and operating the cardiopulmonary resuscitation device while visually checking the position to be compressed using a laser.

[0142] In the step of selecting the compression extender, the compression extender may be provided with two or more different types of compression extenders, and may be selected according to the patient's body type and condition.

[0143] Although the embodiments have been described above with reference to limited drawings, those skilled in the art may apply various technical modifications and variations based on the above. For example, the described techniques may be performed in a different order than described, and / or the components of the described systems, structures, devices, circuits, etc. may be combined or combined in a different manner than described, or may be substituted or replaced by other components or equivalents, and still achieve suitable results.
