Description

[Technical Field]

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

[0002] CPR is an essential first aid measure when the heart stops functioning or has stopped functioning. If not performed promptly, brain damage can begin after four minutes and serious damage can occur to other vital organs. Survival rates drop sharply after 10 minutes. While survival rates typically decrease by 7-10% for every minute of delay in defibrillation, it is known that CPR reduces this by 2.5-5%, meaning that proper CPR significantly improves survival rates. However, even trained personnel often panic when faced with CPR and are unable to perform it properly.

[0003] In accordance with the latest guidelines for cardiopulmonary resuscitation, a system that can provide continuous chest compressions without fatigue and that explores optimal cardiopulmonary resuscitation techniques is required to maintain adequate cardiac output by maintaining a rate of 100 or more compressions per minute at a depth of at least 5 cm and sufficient relaxation between compressions, thereby improving coronary artery pressure, increasing the likelihood of restoration of spontaneous circulation, and reducing damage to vital organs such as the brain and lungs.

[0004] The above-mentioned background art is what the inventors possessed or acquired in the process of deriving the disclosure of the present application, and is not necessarily publicly known information that was disclosed to the general public prior to the filing of this application.

[0033] FIG. 1 is a diagram illustrating a state in which a portable cardiopulmonary resuscitation device according to one embodiment is used.

[0034] Referring to Fig. 1, a portable cardiopulmonary resuscitation device 1 according to one embodiment can be used to perform cardiopulmonary resuscitation (CPR) on a patient P. To ensure high portability, the portable cardiopulmonary resuscitation device 1 according to one embodiment can change its state depending on whether it is in use or not. For example, the portable cardiopulmonary resuscitation device 1 can be used in the state shown in Fig. 1 (e.g., the first state in Fig. 2) when used with a patient P, and can change its state to a portable state shown in Fig. 4 (e.g., the second state in Fig. 4) when stored or transported.

[0035] In one embodiment, in the usage state shown in FIG. 1 , the portable cardiopulmonary resuscitation device 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 device 1 can adjust the position of chest compressions 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 device 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 portable cardiopulmonary resuscitation device 1). For example, the portable cardiopulmonary resuscitation device 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.

[0036] Figure 2 is a perspective view showing a first state of a portable cardiopulmonary resuscitation device 1 according to one embodiment, Figure 3 is a perspective view showing the process of the support frame being separated in a portable cardiopulmonary resuscitation device 1 according to one embodiment, and Figure 4 is a perspective view showing a second state of a portable cardiopulmonary resuscitation device 1 according to one embodiment.

[0037] Referring to FIGS. 2 to 4, a 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 .

[0038] In one embodiment, the main body 100 may be embodied in various forms and may include an input interface (not shown) for inputting user commands. In one embodiment, the main body 100 may be provided with various components (e.g., a compression module 140, a battery 170, a camera 160, etc.) for performing cardiopulmonary resuscitation operations on the patient P. In one embodiment, the main body 100 may include a display (not shown) disposed on its surface 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 is for displaying visual and auditory information and may include a display or a speaker, etc.

[0039] 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. 2. In this case, when the portable cardiopulmonary resuscitation apparatus 1 is used on a patient P as shown in Fig. 1, 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. 4. 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.

[0040] 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 face 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.

[0041] In one embodiment, the main body 100 may include an opening formed through it in a first direction (e.g., the Z-axis direction). The opening may be formed at a central portion based on the direction in which the main body 100 is connected. When the main body 100 is in the first state, the opening may be formed at a portion overlapping 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.

[0042] 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 a vital part of the patient P in a first direction toward the underside of the main body 100, for example, toward the fixed frame 130. A detailed description of the compression module 140 will be provided below.

[0043] In one embodiment, the first connection frame 110 and the second connection frame 120 may each be rotatably connected to the main body 100 .

[0044] 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 can extend from the first portion 102 of the main body 100 in a first length direction. A first connection portion 111 can 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. 2 ). In one embodiment, the first connection frame 110 can be connected to the fixing frame 130 via the first connection portion 111. For example, a connecting rod can be formed in the first connection portion 111 and inserted into a first insertion portion of the fixing frame 130 (described below).

[0045] 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 can extend from the second portion 101 of the main body 100 in a second length direction. A second connection portion 121 can 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. 2 ). In one embodiment, the second connection frame 120 can be connected to the fixing frame 130 via the second connection portion 121. For example, a connecting rod can be formed in the second connection portion 121 and inserted into a second insertion portion of the fixing frame 130 (described below).

[0046] In one embodiment, the first connection frame 110 and the second connection frame 120 can each rotate relative to the main body 100 to change the state of the portable cardiopulmonary resuscitation device 1 between a first state and a second state. In one embodiment, the first connection frame 110 and the second connection frame 120 can rotate relative to the main body 100 to be in the first state (e.g., FIG. 2) in which the first connection portion 111 and the second connection portion 121 are located below the main body 100 and can be coupled to the fixing frame 130. In one embodiment, the first connection frame 110 and the second connection frame 120 can rotate relative to the main body 100 to be in the second state (e.g., FIG. 4) in which the first connection portion 111 and the second connection portion 121 are located above the main body 100.

[0047] 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 patient P's body can be positioned. For example, the portable cardiopulmonary resuscitation apparatus 1 may surround the patient P's body with the seating space at the center. In one embodiment, before the portable cardiopulmonary resuscitation apparatus 1 is converted from the first state to the second state, as shown in FIG. 2 , the fixing frame 130 may be disconnected from the first connecting frame 110 and the second connecting frame 120. In one embodiment, the first connecting frame 110 and the second connecting frame 120 may be rotated relative to the main body 100, so that the portable cardiopulmonary resuscitation apparatus 1 can be converted to the second state. In this case, the first connecting frame 110 and the second connecting frame 120 may 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.

[0048] 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 first connection frame 110 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 relative to the ground from the main body 100 toward the first connection frame 110. 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 relative to the ground from the main body 100 toward the second connection frame 120. 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 shape that curves in a streamlined manner 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 in the first state as shown in FIG. 2, 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 coincide with or be parallel to each other. In this case, the first connection frame 110 and the second connection frame 120 may have a shape that curves in their length directions so that the portable cardiopulmonary resuscitation apparatus 1 can be easily gripped by a user in the second state.

[0049] 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 seating space. When fastened to the first connecting portion 111 and the second connecting portion 121, the fixing frame 130 may serve 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 made 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. 3 during the process of converting the portable cardiopulmonary resuscitation device 1 from the first state to the second state.

[0050] In this manner, when the fixing frame 130 is detachably fastened to the first connecting frame 110 and the second connecting frame 120, cardiopulmonary resuscitation (CPR) on an unconscious patient P can be more easily performed. For example, when the portable CPR 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 placed 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 is positioned within the seating space. In one embodiment, when viewed in a first direction (e.g., the Z-axis direction), the fixing frame 130 overlaps with the compression module 140 for compressing the chest of the patient P, and therefore the fixing frame 130 can also function as an index for locating the chest region of the patient P for chest compression.

[0051] For example, as shown in Figures 2 to 4, the state of the portable cardiopulmonary resuscitation device 1 can be quickly and easily changed due to the rotational movement of the first connecting frame 110 and the second connecting frame 120 relative to the main body 100 and the fastening movement of the fixed frame 130 relative to the first connecting frame 110 and the second connecting frame 120.

[0052] FIG. 5 is a diagram showing the compression extender, battery, and measuring unit of the portable cardiopulmonary resuscitation device 1 according to one embodiment, and FIG. 6 is a block diagram of the portable cardiopulmonary resuscitation device according to one embodiment.

[0053] 5 and 6, the portable cardiopulmonary resuscitation device 1 according to one embodiment may further include a compression extender 160, a battery 170, a measuring unit 150, and a processor 190, which are arranged inside the main body 100. In one embodiment, the compression extender 160, the battery 170, and the measuring unit 150 are hidden by a cover and can be selectively exposed to the outside as needed. For example, the measuring unit 150 can be exposed to the outside to detect the condition of the patient P when the portable cardiopulmonary resuscitation device 1 is in use. In one embodiment, the processor 190 can be provided inside the main body 100.

[0054] However, the positions of the components shown in the drawings are merely examples and are not limiting.

[0055] 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 and provide 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 used as an external device without being provided to the portable cardiopulmonary resuscitation device 1.

[0056] In one embodiment, the measurement unit 150 may sense information related to 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.

[0057] 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 by 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 using 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 via the measurement unit 150, such as information about the cardiac output of the patient P. The processor 190 may determine the compression conditions, compression position, etc. of the chest compressor 141 for the patient P based on the detected information. The processor 190 may set the chest compression position and operation conditions according to a preset algorithm, the description of which will be omitted.

[0058] In one embodiment, the battery 170 may provide power for the operation of the portable cardiopulmonary resuscitation device 1. In one embodiment, the battery 170 may be attached to or detached from the main body 100.

[0059] FIG. 7 is a perspective view of a portable cardiopulmonary resuscitation device 1 according to an embodiment, and FIGS. 8 and 9 are views of a compression module 140 according to an embodiment viewed from different directions.

[0060] 7, 8, and 9, the portable cardiopulmonary resuscitation device 1 can compress a body part of the patient P, such as the chest of the patient P, that is disposed on the fixed frame 130, using the compression module 140. In one embodiment, the compression module 140 can be disposed within an opening in the main body 100.

[0061] 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. 2 ). In one embodiment, the compression module 140 can apply pressure to the chest of the patient P in a first direction toward the bottom of the main body 100 (e.g., the −Z direction in FIG. 7 ). The compression module 140 can change the compression position for the patient P who is placed in a fixed position, for example, on the fixed frame 130.

[0062] 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, one or more position adjustment portions for adjusting the position of the chest compressor 141 relative to the main body 100, and a stopper 144.

[0063] In one embodiment, the chest compressor 141 may be connected to the main body 100 so that its position can be adjusted. When the portable cardiopulmonary resuscitation device 1 is in the first state, the horizontal position of the chest compressor 141 may be adjusted relative to the main body 100 on a plane perpendicular to a first direction (e.g., the XY plane in FIG. 7 ). For convenience 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 below. Changing the horizontal position of the chest compressor 141 relative to the main body 100 may change the part of the patient P at which the chest compressor 141 compresses. 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.

[0064] The compression member 1411 may be located at the 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 along 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 via 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.

[0065] In one embodiment, the compression member 1411 can reciprocate along a first direction by operation of the actuator 1412. The actuator 1412 can operate in response to a signal from the processor 190 so that the compression member 1411 can compress the chest of the patient P at a set pressure for a set period. In one embodiment, the chest compressor 141 can include an encoder 1411 for detecting a signal generated by operation of the actuator 1412 and a switch 1415 for controlling the operation of the actuator 1412.

[0066] In one embodiment, the input handle 1413 may be connected to the upper end of the chest compressor 141. The input handle 1413 may protrude from the upper side of the main body 100, for example. In one embodiment, the input handle 1413 is gripped by a user and may move horizontally together with the chest compressor 141 when it receives a force from the user. In one embodiment, the input handle 1413 may receive 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 the user inputs a first signal (e.g., a signal generated by pushing or pulling the input handle 1413), the input handle 1413 may activate / release a stopper 144, which will be described later, 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 the user inputs an adjustment signal to the input handle 1413 (for example, a signal generated 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 compression device 141 relative to the main body 100.

[0067] In one embodiment, one or more position adjusters are coupled to chest compressor 141 and operable to change the horizontal position of chest compressor 141 relative to main body 100 .

[0068] In one embodiment, the position adjustment portion may include a first position adjustment portion 142 and a second position adjustment portion 143. However, only one of the first position adjustment portion 142 and the second position adjustment portion 143 may be provided.

[0069] In one embodiment, the first position adjustment unit 142 may adjust the horizontal position of the chest compressor 141 relative to a first fixed axis B1, which is at a fixed position on a plane perpendicular to the first direction. In one embodiment, the first fixed axis B1 may be aligned with the first direction (i.e., aligned with the Z-axis). In one embodiment, the first position adjustment unit 142 may be rotatably coupled to the first fixed axis B1 and the chest compressor 141. The first position adjustment unit 142 may adjust the distance between the first fixed axis B1 and the chest compressor 141. In this case, by operating the first position adjustment unit 142, the angle and distance of the chest compressor 141 relative to the first fixed axis B1 may change, thereby changing the horizontal position of the chest compressor 141.

[0070] In one embodiment, the first position adjustment unit 142 may include a first rotation link 1421 rotatably connected to the first fixed axis B1 and a first connecting link 1422 rotatably connected to the first rotation link 1421 and the chest compressor 141. In one embodiment, the first rotation link 1421 may rotate around the first fixed axis B1. For example, the first rotation link 1421 may be connected to a gear disposed on the first fixed axis B1 and may rotate around the first fixed axis 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 rotation link 1421 and a first point on the chest compressor 141, respectively. The first connecting link 1422 is located on the first rotation 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 rotation link 1421 rotating around the first fixed axis B1. The first connecting link 1422 is located at a first point on the chest compressor 141 and can rotate around 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.

[0071] 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., aligned with 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. Thus, 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.

[0072] 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. The second rotation link 1431 may be connected to a gear disposed on the second fixed shaft B2, for example, 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 on the chest compressor 141 and can rotate around 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.

[0073] 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 may be operated by power provided by the second actuator.

[0074] 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 operate in response to a change in the position of the chest compressor 141 due to 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 via the input handle 143. The following description will focus on the case where the first position adjustment unit 142 and the second position adjustment unit 143 are operated by a force applied by the user.

[0075] 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 selectively limit the operation of the first position adjustment unit 142 and the second position adjustment unit 143, thereby preventing the horizontal position of the chest compressor 141 from being arbitrarily changed. 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.

[0076] 10 and 11 are diagrams illustrating a process in which a connection frame according to an embodiment is attached to a support frame.

[0077] 10 and 11, in order to use the portable cardiopulmonary resuscitation device 1, a process of connecting the first connecting frame 110 and the second connecting frame 120 to the fixing frame 130 is required. On the other hand, in order to store or release the portable cardiopulmonary resuscitation device 1, a process of releasing the first connecting frame 110 and the second connecting frame 120 from the fixing frame 130 is required.

[0078] The fixing frame 130 may include insertion portions (e.g., a first insertion portion 132 and a second insertion portion 133) formed at both ends in the length direction. The first connecting portion 111 of the first connecting frame 110 may be inserted into the first insertion portion 132, and the second connecting portion 121 of the second connecting frame 120 may be inserted into the second insertion portion 133.

[0079] The insertion portions 132 and 133 may be recessed into the fixed frame 130 to form insertion spaces. In one embodiment, the fixed frame 130 may include a pair of fixing portions 133 (e.g., a first fixing portion and a second fixing portion) disposed within the pair of insertion portions, respectively. In one embodiment, the fixing portion 133 may include a locking hook 1331 having one side open into which a connecting portion can be inserted, a closing member 1332 that opens and closes the open portion of the locking hook 1331, an elastic body that applies an elastic force so that the closing member 1332 closes the locking hook 1331, and a lever 1333 connected to the closing member 1332 and for operating the closing member 1332. In one embodiment, the lever 1333 is exposed to the outside of the fixed frame 130 and can be operated by a user. When the lever 1333 is operated, the closing member 1332 may move to open the open portion of the locking hook 1331.

[0080] In one embodiment, when the connecting portion 121 of the connecting frame 120 is inserted into the insertion portion 132, the connecting portion 121 may push out the closing member 1332 to open the released portion of the locking hook 1331. When the connecting portion 121 is seated in the locking hook 1331, the closing member 1332 may move to close the locking hook 1331 by the elastic body. Thus, the connecting portion 121 of the connecting frame 120 may be fixed to the fixing frame 130. Meanwhile, in one embodiment, when the lever 1333 is pulled by a user during the process of separating the connecting frame 120 from the fixing frame 130, the closing member 1332 moves to release the locking hook 1331, and the connecting portion 121 of the connecting frame 120 comes out of the locking hook 1331.

[0081] With this structure, the connecting frame can be easily fastened to and detached from the fixed frame 130, and the state of the portable cardiopulmonary resuscitation apparatus 1 can be changed simply and quickly.

[0082] As mentioned above, even if the embodiments are described using limited drawings, a person 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 replaced or substituted by other components or equivalents, and still achieve suitable results.
