Description

Technical Field

[0001] The present disclosure relates to a portable cardiopulmonary resuscitation device and components applicable thereto.Background Art

[0002] Cardiopulmonary resuscitation (CPR) is an essential emergency procedure when cardiac function has ceased or stopped. If prompt action is not taken, brain damage begins after 4 minutes, and severe damage is caused to other vital organs; after 10 minutes, the survival rate drops sharply. Generally, the survival rate decreases by 7-10% for each minute of delay in defibrillation; however, if CPR is performed, the decrease is known to be 2.5-5%. Properly performed CPR significantly improves the survival rate. Nevertheless, even those who have received training may panic when faced with an actual CPR situation, often rendering them unable to properly perform CPR.

[0003] According to the latest cardiopulmonary resuscitation (CPR) guidelines, it is necessary to maintain a compression depth of at least 5 cm at a rate of more than 100 times per minute, and to ensure sufficient recoil between compressions in order to maintain an adequate cardiac output, thereby improving coronary perfusion pressure and increasing the likelihood of return of spontaneous circulation (ROSC), while reducing damage to vital organs such as the brain and lungs. Accordingly, there has been a need for a system capable of providing optimal CPR and continuously delivering chest compressions without fatigue.

[0004] In addition, in conventional chest compression devices, the position of the chest compressor is fixed at the initially installed location, which makes it difficult to quickly respond to installation errors when the patient is unconscious. This often leads to a significant decrease in the patient's chances of survival. That is, the compression position of the chest compressor becomes fixed to a specific location on the patient's chest at the moment the device is initially installed. Therefore, even if the user recognizes that the device has been improperly positioned, it becomes necessary to move the entire device installed on the patient or, depending on the situation, to detach and reattach part of the installed structure, in order to correct the position. In such cases, the patient often exceeds the golden time, making resuscitation difficult, which can result in a critical situation. Consequently, CPR is sometimes performed even while knowing the device is installed in the wrong position.

[0005] Accordingly, there has been a need to improve conventional cardiopulmonary resuscitation devices so as to generate appropriate effects and solve the above-mentioned problems.Prior Patent

[0055] FIG. 1 is a schematic view illustrating the structure of a position change unit of a portable cardiopulmonary resuscitation device including a position change unit according to one embodiment.

[0056] FIG. 2 is a schematic view illustrating the internal connection structure of a portable cardiopulmonary resuscitation device including a position change unit according to one embodiment.

[0057] FIG. 3 is a perspective view schematically illustrating the structure of a distal end of a compression module (10) according to one embodiment.

[0058] A portable cardiopulmonary resuscitation device including a position change unit according to one embodiment comprises a main body and a compression module connected to the main body and configured to press the chest of a patient in a first direction toward a lower side of the main body, wherein the main body includes an opening formed to penetrate in the first direction, the compression module is disposed in the opening, and the compression module may be connected to a position change unit for moving the chest compression position of the patient with two degrees of freedom in a plane perpendicular to the first direction.

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

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

[0061] In one embodiment, the position change handle may include a brake release button formed on one side, and when the brake release button is pressed, the position change handle becomes movable in a plane perpendicular to the first direction, and the compression module may also move in the same plane during movement of the position change handle.

[0062] The position change handle may be locked by the brake when the cardiopulmonary resuscitation device is not in use, and the position may become movable when the release button is pressed.

[0063] In one embodiment, the brake may be electronic, and may further include a brake controller electrically connected to the brake release button, and the movement of the position change handle may be performed manually by an external force applied by the user.

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

[0065] In this way, when the brake release button is pressed, the compression module that had been in close contact with the chest becomes lifted and movable, enabling the user to easily move the module in the plane.

[0066] In one embodiment, the brake may be a mechanical motor type, and the movement of the position change handle may be performed electronically.

[0067] In this case, the electronic movement may be controlled by a digital button system, as used in electronic surgical instruments, where the movement distance is input and controlled, or it may be controlled by a computer or an external remote controller.

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

[0069] The first link group may include a first-1 link and a first-2 link, wherein the first-2 link is fixed to the position of the motor housing, and the first-1 link is connected at one end to the first-2 link via a joint and at the other end to the first brake gear.

[0070] The second link group may also include a second-1 link and a second-2 link, wherein the second-2 link may be connected to the motor housing via a bearing, and the second-1 link is connected at one end to the second-2 link via a joint and at the other end to the second brake gear.

[0071] In one embodiment, a reinforcement plate may be further included between the upper plate and the position change handle, and the reinforcement plate may protect components located on the upper plate from impact caused by external force applied through the handle.

[0072] The reinforcement plate serves to prevent damage to the link or joint parts included in the position change unit when the user grips the handle and pushes it downward, applies lateral force while the brake is engaged, or in the event the product is dropped by the handle, thus preventing vertical or lateral load.

[0073] In one embodiment, the position change unit may include a five-bar linkage structure capable of planar movement with two degrees of freedom.

[0074] As described above, FIG. 2 illustrates a five-bar linkage structure according to one embodiment of the present invention, enabling the position change handle to move with two degrees of freedom in a plane perpendicular to the first direction. However, the technical idea of the present invention includes all structural configurations enabling the position change handle and the compression module to move on a plane and is not limited to the structure shown in FIG. 2.

[0075] A portable cardiopulmonary resuscitation device including a position change unit according to one embodiment comprises a main body and a compression module connected to the main body and configured to press the chest of a patient in a first direction toward a lower side of the main body, wherein the main body includes an opening formed to penetrate in the first direction, the compression module is disposed in the opening, and a column-shaped, detachable compression extension rod is provided at a lower distal end of the compression module.

[0076] The compression module may be formed to pass through the main body, and the distal end of the compression module may be moved to an appropriate chest compression position for resuscitation by using the handle located on the upper side.

[0077] In one embodiment, the compression module may include an extension rod fastening hook formed to protrude outward from the lower distal end, and the compression extension rod may include a stepped portion formed to protrude inward at its upper end, such that the hook and the stepped portion engage with each other to allow the compression extension rod to be mounted to the distal end of the compression module.

[0078] Although the compression extension rod may be mounted to the compression module using various structures, in one example, the compression module includes the hook and the compression extension rod includes the stepped portion, allowing quick attachment and fastening in emergency situations.

[0079] In one embodiment, the compression module may include a handle at the lower distal end for detaching the compression extension rod, and when the user applies an external force to the handle, the hook may retract inward, allowing the compression module and the compression extension rod to be separated.

[0080] The user may press both sides of the handle, causing the hook of the compression module to retract inward and allowing the stepped portion of the compression extension rod to be disengaged. Such a structure may be designed to be simple and intuitive, enabling rapid attachment and detachment of the compression extension rod in urgent situations. This may be particularly useful in cases where CPR must be performed on multiple patients or when the actual chest height of the patient differs from the initially expected value, requiring the replacement of the compression extension rod after it has already been attached once.

[0081] The detachment of the compression extension rod from the compression module may be configured such that the user can apply a light external force, for example by rotating or pressing the handle, to separate it.

[0082] FIG. 4 is a schematic diagram showing a portable cardiopulmonary resuscitation device to which a compression extension rod is mounted, where the left figure shows a state in which no compression extension rod is mounted, the center figure shows a state in which a short compression extension rod is mounted, and the right figure shows a state in which a tall compression extension rod is mounted.

[0083] As shown in FIG. 4, the compression extension rod can be mounted at different heights according to the patient's body type or, depending on the situation, chest compressions may be performed without the compression extension rod being mounted.

[0084] In one embodiment, the compression module may include a laser emission unit located at the center of the distal end, and the compression extension rod may include a through-hole at its center such that the laser emitted from the laser emission unit passes through the compression extension rod.

[0085] The laser emission unit may include a laser pointer lens.

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

[0087] The laser generated from the laser emission unit indicates the compression location on the patient's chest, allowing the user to effectively perform chest compressions at the proper position.

[0088] Additionally, the compression extension rod may also be designed to include a laser pointer lens (not shown) near the central opening. Through this configuration, even when the compression extension rod is mounted, the compression position can still be effectively indicated on the patient's chest.

[0089] In one embodiment, the compression extension rod may be replaceable with various types of extension rods having different heights depending on the patient's body type and situation.

[0090] The compression extension rods may be provided in at least two or more types and transported to the site, where a suitable rod is selected and mounted based on the patient's physique.

[0091] In one embodiment, the compression extension rod may have a height ranging from 30 mm to 130 mm.

[0092] This is an optimal value designed to ensure universality under all conditions, based on setting an appropriate chest compression depth according to the AHA guidelines and referencing statistical data measuring chest width and height by age.

[0093] The inventors have compiled measurement data on chest width and height from various medical datasets and derived the lengths of compression extension rods corresponding to usable chest heights and required compression depths.

[0094] FIG. 5 is a view illustrating a usage state of the portable cardiopulmonary resuscitation device according to one embodiment.

[0095] Referring to FIG. 5, the portable cardiopulmonary resuscitation device (1) according to one embodiment may be used to perform cardiopulmonary resuscitation (CPR) on a patient (P). The device (1) may change its state depending on whether it is in use, in order to maintain high portability. For example, during use on the patient (P), the device (1) may be in a usage state as shown in FIG. 5 (e.g., the first state of FIG. 6), and during storage or transport, it may be in a portable state as shown in FIG. 8.

[0096] In the usage state shown in FIG. 5, the portable cardiopulmonary resuscitation device (1) may perform repetitive chest compressions on the patient (P), who is lying on the ground, at a predetermined depth and cycle. The device (1) may adjust the chest compression position to an optimal location based on the condition of the patient (P), such as the patient's body size or individual heart position. The device (1) may also change its state to allow easy gripping by the user (e.g., the user operating the device (1)) during storage or transport. For example, due to its high portability and ease of use, the device (1) may be used to perform rapid and accurate cardiopulmonary resuscitation on a patient (P) in an emergency situation.

[0097] FIG. 6 is a perspective view illustrating a first state of the portable cardiopulmonary resuscitation device (1) according to one embodiment.

[0098] FIG. 7 is a perspective view illustrating a process in which the connection frame is detached in the portable cardiopulmonary resuscitation device (1) according to one embodiment.

[0099] FIG. 8 is a perspective view illustrating a second state of the portable cardiopulmonary resuscitation device (1) according to one embodiment.

[0100] Referring to FIGS. 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 connection frame (110), a second connection frame (120), and a fixing frame (130).

[0101] In one embodiment, the main body (100) may be implemented in various forms and may include an input interface (not shown) for receiving user commands. Various components for performing resuscitation on the patient (P)-such as the compression module (140), battery (170), and camera (160)-may be disposed in the main body (100). The main body (100) may also include a display unit (not shown) disposed on its surface, which displays various information such as operational data of the portable cardiopulmonary resuscitation device (1) and sensing data related to the patient (P). For example, the display unit may include a display or speaker for providing visual or auditory output.

[0102] In one embodiment, the main body (100), in the first state shown in FIG. 6, may be positioned above the ground. In this state, as shown in FIG. 5, when the portable cardiopulmonary resuscitation device (1) is used on the patient (P), the main body (100) may be positioned above the patient's chest. In the second state, as shown in FIG. 8, the main body (100) may rest directly on the ground. Accordingly, depending on the state of the portable cardiopulmonary resuscitation device (1), the relative position of the main body (100) within the device (1) may change.

[0103] In one embodiment, the main body (100) may have a form extending 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 opposite 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) in opposite directions. The main body (100) may include a first portion (102) to which the first connection frame (110) is connected (e.g., the portion of the main body facing the +X direction), and a second portion (101) opposite the first portion (102), to which the second connection frame (120) is connected (e.g., the portion of the main body facing the -X direction).

[0104] In one embodiment, the main body (100) may include an opening formed to penetrate in a first direction (e.g., the Z-axis direction). The opening may be formed in the central region along the longitudinal direction of the main body (100). When the main body (100) is in the first state, the opening may be formed in an area that overlaps with the fixing frame (130) when viewed in the first direction. The compression module (140) may be disposed in the opening, and components of the compression module (140) other than certain parts (e.g., the compression member, input handle (1413), etc.) may be covered by other parts to prevent exposure. Detailed description thereof is omitted.

[0105] In one embodiment, the compression module (140) may be connected to the main body (100). For example, the compression module (140) may be connected to the main body (100) so as to be positioned within the opening. The compression module (140) may press the chest of the patient (P) in the first direction, for example, toward the fixing frame (130), from the lower side of the main body (100). A detailed description of the compression module (140) will be provided later.

[0106] In one embodiment, the first connection frame (110) and the second connection frame (120) may be rotatably connected to the main body (100).

[0107] In one embodiment, the first connection frame (110) may be connected to the first portion (102) of the main body (100) and may be rotatable about a first rotation axis (A1) with respect to the main body (100). The first connection frame (110) may extend in a first longitudinal direction from the first portion (102) of the main body (100). A first connection part (111) may be formed at the extended end of the first connection frame (110) (e.g., the end of the first connection frame facing the -Z direction in FIG. 6). The first connection frame (110) may be connected to the fixing frame (130) via the first connection part (111). For example, the first connection part (111) may be provided with a connection rod configured to be inserted and fastened into a first insertion part of the fixing frame (130), which will be described later.

[0108] In one embodiment, the second connection frame (120) may be connected to the second portion (101) of the main body (100) and may be rotatable about a second rotation axis (A2) with respect to the main body (100). The second connection frame (120) may extend in a second longitudinal direction from the second portion (101) of the main body (100). A second connection part (121) may be formed at the extended end of the second connection frame (120) (e.g., the end facing the -Z direction in FIG. 6). The second connection frame (120) may be connected to the fixing frame (130) via the second connection part (121). For example, a connection rod may be formed at the second connection part (121) for insertion and fastening into a second insertion part of the fixing frame (130), which will be described later.

[0109] In one embodiment, each of the first connection frame (110) and the second connection frame (120) may rotate relative to the main body (100) to change the state of the portable cardiopulmonary resuscitation device (1) to either the first state or the second state. The first and second connection frames (110, 120) may rotate such that the first and second connection parts (111, 121) are positioned below the main body (100) and are engageable with the fixing frame (130), forming the first state (e.g., FIG. 6). The connection frames may also rotate so that the connection parts (111, 121) are positioned above the main body (100), forming the second state (e.g., FIG. 8).

[0110] In one embodiment, in the first state of the portable cardiopulmonary resuscitation device (1), the first and second connection frames (110, 120) may be connected to the fixing frame (130). In this case, the main body (100), the first connection frame (110), the second connection frame (120), and the fixing frame (130) may form an accommodation space where the body of the patient (P) can be placed. For example, the device (1) may surround the patient (P)'s body with the accommodation space at the center. Before transitioning from the first state to the second state, as shown in FIG. 7, the fixing frame (130) may be disconnected from the first and second connection frames (110, 120). By rotating the connection frames relative to the main body (100), the device (1) may be transitioned into the second state. In the second state, the first and second connection frames (110, 120) may serve as carrying handles that can be gripped by the user. For example, gripping grooves may be formed at the ends of the connection frames (110, 120) to allow the user to securely hold them by hand.

[0111] In one embodiment, the distance between the first connection frame (110) and the second connection frame (120) may vary depending on their rotational positions relative to the main body (100). The first rotation axis (A1) and the second rotation axis (A2) may intersect at a point beneath 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 with respect to the ground (e.g., the XY-plane). In this case, the first rotation axis (A1) may incline upward from the main body (100) toward the first connection frame (110). Likewise, the second rotation axis (A2), about which the second connection frame (120) rotates, may also incline upward from the main body (100) toward the second connection frame (120). Under these conditions, the distance between the first and second connection frames (110, 120) in the second state may be smaller than in the first state.

[0112] In one embodiment, the first and second connection frames (110, 120) may be streamlined and curved along their longitudinal directions. For example, based on the first state shown in FIG. 6, the distance between the frames may initially increase as they extend away from the main body (100), then narrow at the connection parts (111, 121). In such a configuration, the connection parts (111, 121) may define a minimum spacing in the second state of the portable cardiopulmonary resuscitation device (1).

[0113] In another embodiment, the first and second rotation axes (A1, A2) may coincide or run parallel to each other. In this case, the connection frames (110, 120) may be shaped in a curved manner along their lengths to allow the user to easily grip them in the second state of the device (1).

[0114] In one embodiment, the fixing frame (130) may be detachably coupled to the first and second connection frames (110, 120). For example, in the first state of the portable cardiopulmonary resuscitation device (1), the fixing frame (130) may be placed on the ground, and its ends may be fastened to the first and second connection parts (111, 121), thereby supporting the patient's (P) back in the accommodation space.

[0115] In the connected state, the fixing frame (130) may serve as a support base that enables the first connection frame (110), the second connection frame (120), and the main body (100) to be stably erected on the ground. A support section (131) may be formed on the surface of the fixing frame (130), particularly on the side that contacts the patient's body, to provide comfortable support. The support section may be made of a compressible material such as sponge or rubber.

[0116] In one embodiment, during the transition from the first state to the second state of the portable cardiopulmonary resuscitation device (1), the fixing frame (130) may be separated from the connection frames (110, 120), as illustrated in FIG. 7.

[0117] In this way, when the fixing frame (130) is detachably coupled to the first connection frame (110) and the second connection 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) may first be placed on the ground, and the patient (P) may be positioned on the upper surface of the fixing frame (130), such as the support section. Then, the first connection frame (110) and the second connection frame (120) may be coupled to the fixing frame (130), thereby allowing the patient (P) to be located within the accommodation space. In one embodiment, when viewed in the first direction (e.g., the Z-axis direction), the fixing frame (130) overlaps with the compression module (140) used for chest compression of the patient (P), and thus the fixing frame (130) may also function as a reference for positioning the patient's chest for compression.

[0118] For example, as shown in FIGS. 6 to 8, the state of the portable cardiopulmonary resuscitation device (1) can be changed quickly and easily through rotational movement of the first and second connection frames (110, 120) relative to the main body (100), and coupling of the fixing frame (130) to the connection frames (110, 120).

[0119] FIG. 9 is a diagram illustrating the compression module extension, battery, and sensing unit of the portable cardiopulmonary resuscitation device (1) according to one embodiment.

[0120] FIG. 10 is a block diagram of the portable cardiopulmonary resuscitation device according to one embodiment.

[0121] Referring to FIGS. 9 and 10, the portable cardiopulmonary resuscitation device (1) according to one embodiment may further include a compression module extension (105), a battery (170), a sensing unit (150), and a processor (190), all of which may be disposed inside the main body (100). In one embodiment, the compression module extension (105), battery (170), and sensing unit (150) may be covered by an exterior cover and selectively exposed as needed. For example, the sensing unit (150) may be exposed externally when the device (1) is in use, to detect the condition of the patient (P). The processor (190) may be housed inside the main body (100).

[0122] The positions of the respective components shown in the drawings are exemplary and are not limited thereto.

[0123] In one embodiment, the portable cardiopulmonary resuscitation device (1) may further include a camera (C). The camera (C) may capture video of the chest of the patient (P), who is positioned in the accommodation space and receiving compressions from a chest compressor (141) to be described later. The captured video may be displayed on a display or analyzed by the processor (190). By imaging the patient's chest, the camera (C) may provide the processor (190) with information useful for identifying the appropriate chest compression position for the patient (P). The camera (C) may be built into the device (1) or implemented as an external device.

[0124] The sensing unit (150) may sense information related to the chest compression being performed on the patient (P). For example, the sensing unit (150) may include one or more sensors such as pressure sensors, torque sensors, or load cells, for real-time measurement of force or torque generated when the chest compressor (141) contacts the patient (P). The sensing unit (150) may also include one or more sensors for detecting the patient's biometric information. For example, the sensing unit (150) may include sensors for measuring various physiological signals of the patient (P), such as cardiac output, blood pressure, electrocardiogram (ECG), and blood oxygen saturation (SpO 2 ).

[0125] The processor (190) may control the operation of the portable cardiopulmonary resuscitation device (1). Based on information detected via the camera (C), sensing unit (150), and other components, the processor (190) may determine optimal compression conditions for the patient (P). For example, the processor (190) may identify an initial chest compression point suitable for the patient (P) via the camera (C), and control the position of the compression module (140) so that the chest compressor (141) can compress the detected point.

[0126] The processor (190) may also use information detected by the sensing unit (150), such as the patient's cardiac output, to determine and apply optimal chest compression conditions. Based on the detected information, the processor (190) may determine the compression conditions and compression position for the chest compressor (141) with respect to the patient (P). Setting the chest compression position and operation conditions by the processor (190) may be performed according to a predefined algorithm. Detailed description thereof is omitted.

[0127] In one embodiment, the battery (170) may supply electrical power for operating the portable cardiopulmonary resuscitation device (1). The battery (170) may be attachable to and detachable from the main body (100).

[0128] FIG. 11 is a perspective view of the portable cardiopulmonary resuscitation device (1) according to one embodiment, and FIGS. 12 and 13 are views showing the compression module (140) from different directions.

[0129] The compression module shown in FIGS. 11 to 13 is merely an example, and the end portion may also be configured to allow attachment of a compression extension, such as the one illustrated in FIG. 3.

[0130] Referring to FIGS. 11, 12, and 13, the portable cardiopulmonary resuscitation device (1) may compress the chest or another part of the patient's body (P), positioned on the fixed frame (130), via the compression module (140). In one embodiment, the compression module (140) may be disposed within an opening in the main body (100).

[0131] In one embodiment, the compression module (140) may operate when the portable cardiopulmonary resuscitation device (1) is in a first state (e.g., the first state shown in FIG. 2a). The compression module (140) may press down on the patient's (P) chest in a first direction facing the lower side of the main body (100) (e.g., the -Z direction in FIG. 6). The compression module (140) may allow adjustment of the compression location with respect to a fixed position, such as a patient (P) laid on the fixed frame (130).

[0132] In one embodiment, the compression module (140) may include a chest compressor (141) configured to compress the patient's (P) body, an input handle (1413), one or more position adjustment units for adjusting the position of the chest compressor (141) relative to the main body (100), and a stopper (144).

[0133] In one embodiment, the chest compressor (141) may be adjustably connected to the main body (100). When the portable cardiopulmonary resuscitation device (1) is in the first state, the horizontal position of the chest compressor (141) on a plane perpendicular to the first direction (e.g., the XY plane in FIG. 6) may be adjusted relative to the main body (100). Hereinafter, for convenience, 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) changes, the area of the patient (P) being compressed may also change. The horizontal position of the chest compressor (141) may be adjusted to correspond to the optimal compression area detected by the processor (190). The chest compressor (141) may include a compression member (1411), an actuator (1412), an encoder (1414), and a switch (1415).

[0134] The compression member (1411) may be located at the lower end of the chest compressor (141). Depending on the operation of the chest compressor (141), the compression member (1411) may be displaced in the first direction relative to the main body (100). For example, the compression member (1411) may reciprocate along the first and opposite directions to repeatedly compress the patient's (P) chest. The compression member (1411) may contact the patient's (P) chest through its lower end. In another example, a separate contact member may be replaceably connected to the lower end of the compression member (1411) for contact with the patient's (P) chest.

[0135] In one embodiment, the compression member (1411) may reciprocate in the first direction according to the operation of the actuator (1412). The actuator (1412), under signals from the processor (190), may operate the compression member (1411) to apply pressure to the patient's (P) chest at a set cycle and pressure. The chest compressor (141) may include an encoder (1414) for detecting signals related to the actuator's (1412) operation and a switch (1415) for controlling the actuator's (1412) operation.

[0136] In one embodiment, the input handle (1413) may be connected to the upper part of the chest compressor (141) and may protrude upward from the main body (100). The input handle (1413) may be gripped by the user and moved horizontally together with the chest compressor (141) under user-applied force. The input handle (1413) may receive a position adjustment signal from the user, such as force applied to the handle. For example, upon receiving a first signal (e.g., a push or pull motion), the input handle (1413) may activate or release the stopper (144), thereby allowing the position adjustment unit to adjust or fix the horizontal position of the chest compressor (141). Alternatively, the input handle (1413) may cause the position adjustment unit to operate in response to the signal and adjust the horizontal position of the chest compressor (141) relative to the main body (100).

[0137] In one embodiment, the one or more position adjustment units may be connected to the chest compressor (141) and operate to change its horizontal position relative to the main body (100).

[0138] 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) or the second position adjustment unit (143) may be provided.

[0139] In one embodiment, the first position adjustment unit (142) may adjust the horizontal position of the chest compressor (141) relative to a first fixed shaft (B1) located at a fixed position on a plane perpendicular to the first direction. The first fixed shaft (B1) may be aligned with the first direction (i.e., parallel to the Z-axis). The first position adjustment unit (142) may be rotatably connected to both the first fixed shaft (B1) and the chest compressor (141), and may adjust the distance between them. Accordingly, rotation of the first position adjustment unit (142) may change both the angle and distance of the chest compressor (141) relative to the first fixed shaft (B1), thereby adjusting its horizontal position.

[0140] In one embodiment, the first position adjustment unit (142) may include a first rotary link (1421) rotatably connected to the first fixed shaft (B1), and a first connecting link (1422) rotatably connected to both the first rotary link (1421) and a first point of the chest compressor (141). The first rotary link (1421) may rotate about the first fixed shaft (B1), for example by being connected to a gear arranged on the shaft and driven thereby. The first connecting link (1422) may be located on the first rotary link (1421) and rotate about a first connecting axis (C1) parallel to the first fixed shaft (B1). Rotation of the first rotary link (1421) about the first fixed shaft (B1) may change the position of the first connecting axis (C1). The first connecting link (1422), located at a first point of the chest compressor (141), may rotate about a first center axis (D1) parallel to the first connecting axis (C1). This structure allows unrestricted adjustment of the horizontal position of the chest compressor (141) within the main body (100).

[0141] In one embodiment, the second position adjustment unit (143) may adjust the horizontal position of the chest compressor (141) relative to a second fixed shaft (B2) located at a fixed position on a plane perpendicular to the first direction. The second fixed shaft (B2) may be aligned with the first direction (i.e., parallel to the Z-axis). The second position adjustment unit (143) may be rotatably connected to both the second fixed shaft (B2) and the chest compressor (141), and may adjust the distance between them. Thus, the angle and distance of the chest compressor (141) relative to the second fixed shaft (B2) may change, adjusting its horizontal position.

[0142] In one embodiment, the second position adjustment unit (143) may include a second rotary link (1431) rotatably connected to the second fixed shaft (B2), and a second connecting link (1432) rotatably connected to both the second rotary link (1431) and a second point of the chest compressor (141). The second rotary link (1431) may rotate about the second fixed shaft (B2), for example, by being connected to a gear installed on the shaft and driven accordingly. The second connecting link (1432), located on the second rotary link (1431), may rotate about a second connecting axis (C2) parallel to the second fixed shaft (B2). As the second rotary link (1431) rotates about the second fixed shaft (B2), the position of the second connecting axis (C2) may change. The second connecting link (1432), located at a second point of the chest compressor (141), may rotate about a second center axis (D2) parallel to the second connecting axis (C2). This structure enables unrestricted adjustment of the horizontal position of the chest compressor (141) within the main body (100) by the rotation of the second rotary link (1431) and the second connecting link (1432).

[0143] In one embodiment, the first position adjustment unit (142) and the second position adjustment unit (143) support the chest compressor (141) from both sides, enabling more stable horizontal position adjustment. At least one of the first or second position adjustment units (142, 143) may be connected to a second actuator (not shown) and may be driven by power supplied by the actuator.

[0144] In one embodiment, 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 accordance with the position change caused by the operation of the first position adjustment unit (142). However, this is only an example, and the first position adjustment unit (142) and the second position adjustment unit (143) may be operated by a force applied by a user via the input handle (1413). The following description will focus on the case in which the first and second position adjustment units are operated by a user-applied force.

[0145] 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 respectively connected to the first and second position adjustment units (142, 143). The stopper (144) may selectively restrict the operation of the first and second position adjustment units (142, 143) to prevent unintended horizontal movement of the chest compressor (141). In one embodiment, the stopper (144) may be mechanically actuated by manual operation. Alternatively, the stopper may be automatically actuated in response to a control signal (e.g., from the processor (190) or a user input), thereby restricting the operation of the position adjustment unit.

[0146] According to another embodiment, a method of using a portable cardiopulmonary resuscitation device including a position movement unit includes: mounting the portable CPR device, which comprises a main body and a compression module connected to the main body and pressing a patient's chest in a first downward direction, on the patient; pressing a brake release button; grasping a position movement handle and moving the compression module to an appropriate chest compression position; releasing the brake release button; and compressing the chest using the compression module.

[0147] In one embodiment, the step of moving the compression module may include moving the compression module with two degrees of freedom on a plane perpendicular to the first direction. The portable CPR device including the position movement unit may be the device described in the embodiments of the present invention.

[0148] According to still another embodiment, a method of using a portable CPR device including a position movement unit includes: identifying the patient's body type; selecting a compression extender based on the patient's body and situation; mounting the compression extender on the compression module; and driving the CPR device while visually confirming the compression position through a laser. In the step of selecting the compression extender, two or more different types of compression extenders may be prepared in advance and selected according to the patient's body type and situation.

[0149] Although the embodiments above have been described with reference to limited drawings, it will be understood by those skilled in the art that various modifications and changes may be made based on the above without departing from the spirit of the invention. For example, the described techniques may be performed in a different order or the described system, structure, apparatus, or circuit components may be combined or replaced with other elements or equivalents to achieve suitable results.
