CPR assistance device

[0001] Cross-reference regarding related applications

[0002] This application claims the benefit of priority to Korean Patent Application No. 10-2024-0161583 filed on November 14, 2024, the full text of which is incorporated by reference into this specification.

[0003] The present invention relates to a cardiopulmonary resuscitation assistance device.

[0004] Cardiopulmonary resuscitation (CPR) is an emergency procedure used when the heart stops functioning or breathing ceases. In the case of cardiac arrest, failure to take prompt action can lead to death or severe brain damage, so it is crucial for the bystander who first discovers the patient to perform CPR quickly.

[0005] For cardiopulmonary resuscitation, in cases of respiratory failure or respiratory arrest, first check for consciousness and secure the airway, then perform artificial respiration, and to restore heart function, perform cardiac massage. The artificial respiration method is a chest compression cardiac massage method in which blood is ejected by compressing the heart by pressing the sternum 4 to 5 cm downward toward the spine.

[0006] According to the guidelines for cardiopulmonary resuscitation with chest compressions, for chest compression CPR, place the heel of one hand on the lower half of the sternum in the center of the chest and place the other hand on top of it with your fingers interlaced. For adults, the depth of chest compressions should be at least 5 cm and no more than 6 cm, and the rate should be at least 100 and no more than 120 times per minute.

[0007] However, excluding emergency medical personnel, it is common for the general public to lack experience with cardiopulmonary resuscitation (CPR), and in emergency situations, they often fail to perform CPR properly, missing the golden time to save lives.

[0008] On the other hand, when cardiopulmonary resuscitation is not performed correctly, similar to when it is ineffective, death may occur due to secondary injuries such as rib fractures caused by excessive compression at an incorrect location, an incorrect number of repetitions, or an incorrect speed of execution.

[0009] The present invention provides a cardiopulmonary resuscitation assistance device that enables anyone to perform cardiopulmonary resuscitation easily, safely, and accurately.

[0010] A cardiopulmonary resuscitation assistance device according to one embodiment of the present invention comprises a main body that can be folded for storage and unfolded and has a compression position formed at a preset position; a fixing part disposed at the lower part of the compression position and capable of being coupled to a patient; a position indicator chip part disposed at the fixing part; a sensor part disposed at the upper part of the position indicator chip part and connected to the main body and detecting the position of the position indicator chip part; and a control part electrically connected to the position indicator chip part and the sensor part.

[0011] The control unit can generate an alert when the sensor unit moves out of the preset radius of the position indicator chip unit.

[0012] The above cardiopulmonary resuscitation assistance device may further include a coupling part connected to the main body and which fixes the unfolded main body to the patient so as not to move.

[0013] The above cardiopulmonary resuscitation assistance device may further include a circuit part formed along the periphery of the compression location part and connected to the control part, a pressure sensor connected to the circuit part and installed in the compression location part, and a 6-axis inertial sensor connected to the circuit part and positioned adjacent to the pressure sensor.

[0014] The pressure sensor is separated from the 6-axis inertial sensor, and the pressure sensor may be arranged in multiple numbers along the circumferential direction relative to the 6-axis inertial sensor.

[0015] The above cardiopulmonary resuscitation assistance device may further include a display unit positioned on the main body, electrically connected to the control unit, and capable of outputting voice and video information.

[0016] On the surface of the main body, a plurality of folding lines are formed in a spaced-apart intersecting shape, and the armpit position, the compression position, and the cardiopulmonary resuscitation sequence may be diagrammed.

[0017] The above body may be made of any one selected from the group consisting of paper, vinyl, fabric, and combinations thereof.

[0018] The above cardiopulmonary resuscitation assistance device may further include a sheet member that is positioned on the lower surface of the main body, connected to the control unit, and capable of generating heat.

[0019] The above cardiopulmonary resuscitation assistance device may further include a packaging pack having a storage space for containing the main body.

[0020] Inside the above packaging pack, instructions for using the above cardiopulmonary resuscitation assistance device and the sequence of cardiopulmonary resuscitation may be diagrammed.

[0021] According to an embodiment of the present invention, the sensor unit detects the position of the position indicator chip unit in real time to verify whether the compression position is accurate, and generates an alert if the position deviates from a preset radius. This allows the user to continuously maintain the correct compression position, thereby increasing the accuracy of the compression position, which is a key element of cardiopulmonary resuscitation, and has the effect of significantly improving the patient's survival rate.

[0022] According to an embodiment of the present invention, although it may be difficult for beginners or medical non-professionals attempting cardiopulmonary resuscitation for the first time to maintain the correct compression position, the method helps them learn the correct cardiopulmonary resuscitation method by guiding the compression position through real-time notifications, and has the effect of being useful during cardiopulmonary resuscitation training.

[0023] According to an embodiment of the present invention, since an immediate notification occurs when the compression position is misaligned, the CPR practitioner can quickly adjust the position to continue appropriate compressions without interruption, thereby increasing the consistency of CPR execution and enabling effective cardiac compressions, particularly in emergency situations.

[0024] According to an embodiment of the present invention, since compression location detection and notification occur, the CPR practitioner can perform CPR with confidence in the CPR assistance device without the need to constantly worry about the compression location. This provides a sense of psychological stability to the user, particularly in emergency situations where tension may be high, thereby maximizing the effectiveness of CPR.

[0025] According to an embodiment of the present invention, the position of cardiopulmonary resuscitation (CPR) is standardized and accurate CPR can be performed through the detection of the compression position by the control unit and the notification function that occurs when the compression position is deviated. As a result, various users can maintain consistent CPR quality and have the effect of increasing the patient's chances of survival.

[0026] According to an embodiment of the present invention, the neck coupling member is fixed around the neck and the lower coupling member is fixed on both lower sides, thereby preventing the main body from shaking when compressing the CPR subject, thus helping the CPR performer to perform CPR stably and enabling efficient CPR.

[0027] According to the present embodiment, the pressure sensor and the 6-axis inertial sensor detect the intensity, position, and movement of the compression in real time and provide feedback, thereby enabling accurate cardiopulmonary resuscitation.

[0028] According to the present embodiment, a sheet member equipped with a heating function can provide a warm temperature to a CPR subject during CPR. This can prevent a drop in body temperature that the CPR subject may experience during CPR, which is an important effect because a drop in body temperature can pose a life-threatening risk. Maintaining an appropriate body temperature can contribute to increasing the likelihood of recovery for the CPR subject.

[0038] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings so that those skilled in the art can easily implement the present invention. However, the present invention may be embodied in various different forms and is not limited to the embodiments described herein. Throughout the specification, similar parts are denoted by the same reference numerals.

[0039] Then, a cardiopulmonary resuscitation assistance device according to one embodiment of the present invention will be described with reference to FIGS. 1 to 5.

[0040] Referring to FIGS. 1 to 5, the cardiopulmonary resuscitation assistance device (1) according to the present embodiment includes a main body (20), a fixing part (30), a position indicator chip part (41), a sensor part (42), and a control part (50), enabling anyone to perform cardiopulmonary resuscitation easily, safely, and accurately. The cardiopulmonary resuscitation assistance device (1) may further include a packaging pack (10).

[0041] The packaging pack (10) forms the outer shape of the cardiopulmonary resuscitation assist device (1) and has a storage space (not shown) formed inside. The storage space is open to one side. The packaging pack (10) has a structure that allows the cardiopulmonary resuscitation assist device (1) to be mounted at a placement location. Accordingly, a loop groove is formed in the packaging pack (10). Additionally, an attachment member (not shown) that can be attached to the placement location is formed on the outer surface of the packaging pack (10). The attachment member may be an adhesive sheet, Velcro tape, etc.

[0042] The packaging pack (10) has a unfolding structure. Accordingly, the packaging pack (10) can be unfolded as shown in Figure 2. On the inner surface of the packaging pack (10), instructions for use of the cardiopulmonary resuscitation assistance device (1) and the sequence of cardiopulmonary resuscitation are diagrammed. Accordingly, anyone can easily use the cardiopulmonary resuscitation assistance device (1) and perform cardiopulmonary resuscitation by looking at the diagrammed images.

[0043] The packaging pack (10) can be made of paper or the like. However, the packaging pack (10) can also be made of plastic, fabric or the like.

[0044] The main body (20) has a predetermined width and is folded and stored in the storage space of the packaging pack (10). Accordingly, the main body (20) can be protected from external conditions such as dust and moisture by the packaging pack (10). The main body (20) can be pulled out of the packaging pack (10) through the opening of the storage space and unfolded as shown in FIG. 3. The unfolded main body (20) can be placed on the upper body of the cardiopulmonary resuscitation subject.

[0045] A folding line (21) is formed on one side (top surface) of the unfolded main body (20). Multiple folding lines (21) are formed at intervals in the vertical and horizontal directions of the main body (20). The main body (20) can be folded again along the folding lines (21).

[0046] On one side of the main body (20), a compression position portion (24) indicating a compression position during cardiopulmonary resuscitation is formed. Additionally, an armpit position portion (23) is formed on one side of the main body (20) in a direction away from the other side. The armpit position portion (23) is formed between the one side and the compression position portion (24). When the main body (20) is placed on a person requiring cardiopulmonary resuscitation, the armpit position portion (23) is positioned in the armpit area. Then, the compression position portion (24) is positioned at the compression position of the person requiring cardiopulmonary resuscitation. Therefore, the compression position portion (24) can be accurately positioned at the compression position.

[0047] A concave groove (22) is formed on one side of the main body (20). When the armpit positioning portion (23) is located in the armpit area, the concave groove (22) is located in the neck area of ​​the cardiopulmonary resuscitation subject and can wrap around the neck.

[0048] One side of the main body (20) has a diagram of the cardiopulmonary resuscitation sequence. This allows anyone to easily check the diagram of the cardiopulmonary resuscitation sequence and perform cardiopulmonary resuscitation themselves.

[0049] The main body (20) may be made of paper. However, the main body (20) may also be made of vinyl or fabric, etc. The material of the main body (20) may vary depending on the design of the cardiopulmonary resuscitation assistance device (1).

[0050] The fixed part (30) is positioned on the other side (bottom surface) of the main body (20) corresponding to the pressure position part (24). The upper surface of the fixed part (30) is connected to the main body (20). The fixed part (30) and the main body (20) are connected by a cushioning member (P). Accordingly, the upper surface of the fixed part (30) and the other side of the main body (20) can maintain a predetermined distance. However, when the pressure position part (24) is pressed, the cushioning member (P) is compressed, and the other side of the main body (20) can come into contact with the upper surface of the fixed part (30). When the pressure force of the pressure position part (24) is removed, the other side of the main body (20) can be separated from the upper surface of the fixed part (30) by the cushioning force of the cushioning member (P).

[0051] An adhesive layer (31) is formed on the lower surface of the fixing part (30). A release liner (not shown) is attached to the adhesive layer (31). When the release liner is removed, the adhesive layer (31) can be attached and fixed to the cardiopulmonary resuscitation subject.

[0052] With the fixation of the adhesive layer (31), the main body (20) is fixed to the cardiopulmonary resuscitation subject, so that the compression position (24) remains in the correct position without being twisted. Therefore, the cardiopulmonary resuscitation practitioner can accurately compress the compression position.

[0053] The location indicator chip (41) is coupled to the fixed part (30). The location indicator chip (41) can utilize Radio Frequency Identification (RFID) technology. Accordingly, the location indicator chip (41) has an RFID tag structure.

[0054] The sensor part (42) is coupled to the other side of the main body (20) facing the position indicator chip part (41). The sensor part (42) is separated from the position indicator chip part (41) by a cushioning member (P). However, when the pressure position part (24) is pressed, the sensor part (42) can come into contact with the position indicator chip part (41). The sensor part (42) may have an RFID reader structure.

[0055] However, the position indicator chip part (41) may be coupled to the other side of the main body (20), and the sensor part (42) may be coupled to the fixed part (30). The positions of the position indicator chip part (41) and the sensor part (42) may vary depending on the design of the cardiopulmonary resuscitation assistance device (1).

[0056] The control unit (50) is electrically connected to the position indicator chip unit (41) and the sensor unit (42). The control unit (50), the position indicator chip unit (41), and the sensor unit (42) continuously position signals. The control unit (50) sets the recognition range of the sensor unit (42) through software. For example, a radius of 20 mm to 30 mm is set centered on the position indicator chip unit (41). When the position indicator chip unit (41) and the sensor unit (42) are within the radius range, no notification is generated, but when they go outside the range, a notification is generated. The notification (55) may be a warning light made of a light-emitting diode (LED) or a warning sound (guidance message) through a speaker. In the case of the warning light, it may be red or green, and it may be green when within the radius range and red when outside the radius range. When the radius range of the warning sound is exceeded, it indicates that the distance has been exceeded. The warning light and the warning sound may occur simultaneously.

[0057] That is, the control unit (50) does not generate an alert when the location indicator chip unit (41) and the sensor unit (42) are within the radius range while the cardiopulmonary resuscitation practitioner is repeatedly compressing the compression location unit (24). However, when the location indicator chip unit (41) and the sensor unit (42) move out of the radius range, the control unit (50) immediately recognizes this and generates an alert. Afterward, the alert is stopped when they are within the radius. Accordingly, the cardiopulmonary resuscitation practitioner corrects their posture and performs compression again at the compression location unit (24).

[0058] Accordingly, according to the present embodiment, the sensor unit (42) detects the position of the position indicator chip unit (41) in real time to verify whether the compression position is accurate, and generates an alert if the position deviates from a preset radius, so that the user can continuously maintain the correct compression position, thereby increasing the accuracy of the compression position, which is a key element of cardiopulmonary resuscitation, and significantly improving the survival rate of the patient.

[0059] In addition, while it may be difficult for beginners or non-medical professionals attempting CPR for the first time to maintain the correct compression position, real-time notifications guide the compression location, helping them master the proper CPR method, and it can also be usefully applied during CPR training.

[0060] Next, another embodiment of the present invention will be described with reference to FIG. 6.

[0061] Referring to Figure 6, the cardiopulmonary resuscitation assistance device (2) according to the present embodiment has most of the components of the embodiment described with reference to Figures 1 to 5, and further includes a coupling part (60).

[0062] The coupling part (60) according to the present embodiment secures the main body (20) to the cardiopulmonary resuscitation subject so that it does not move. The coupling part (60) includes a neck coupling member (61) and a lower coupling member (62).

[0063] The neck connecting member (61) is formed in the shape of a band. One end of the neck connecting member (61) is connected to one side of the concave groove (22), and the other end is separated. A connecting means (611) is formed at the other end of the neck connecting member (61). The connecting means (611) may be composed of a snap button, a belt, double-sided tape, etc. A target means to which the connecting means (611) of the neck connecting member (61) is connected is arranged at the other side of the concave groove (22).

[0064] Through the neck connecting member (61), one side of the main body (20) is fixed to the neck of the cardiopulmonary resuscitation subject and does not move.

[0065] The lower connecting member (62) is formed on both sides of the other side of the main body (20). The lower connecting member (62) is formed in the shape of a clamp. The lower connecting member (62) is connected to the main body (20) through an elastic band. Through the lower connecting member (62), the other side of the main body (20) is fixed to the cardiopulmonary resuscitation subject and does not move.

[0066] The lower connecting member (62) is formed as a clamp structure, allowing for quick attachment in emergency situations so that cardiopulmonary resuscitation can be performed quickly.

[0067] In this way, the main body (20) is firmly fixed to the cardiopulmonary resuscitation subject through the connecting part (60), so that the compression position part (24) can be continuously maintained in the correct position even under repeated compression.

[0068] Accordingly, according to the present embodiment, the neck connecting member (61) is fixed around the neck and the lower connecting member (62) is fixed on both lower sides, so that the main body (20) does not shake when compressed, thereby helping the CPR practitioner to perform CPR stably and enabling efficient CPR.

[0069] Other configurations may be applied as they are from the embodiments of FIGS. 1 to 5.

[0070] Next, another embodiment of the present invention will be described with reference to FIGS. 7 and FIGS. 8.

[0071] Referring to FIGS. 7 and 8, the cardiopulmonary resuscitation assistance device (3) according to the present embodiment has most of the components of the embodiment described with reference to FIGS. 1 to 6, and further includes a circuit part (51), a pressure sensor (52), a 6-axis inertial sensor (53), and a rear surface (20a).

[0072] The rear surface (20a) is attached to the other side of the main body (20). Here, the rear surface (20a) is formed by attaching a sheet of a shape corresponding to the main body (20) to the other side of the main body (20). However, the rear surface (20a) may be the other side of the main body (20).

[0073] The circuit section (51) is formed on the rear surface (20a) corresponding to the pressure position section (24). The circuit section (51) is electrically connected to the control section (50).

[0074] The pressure sensor (52) is connected to the circuit section (51) and is positioned at the center of the compression position section (24). The pressure sensor (52) can measure the intensity of the pressure applied during the cardiopulmonary resuscitation process. The pressure sensor (52) detects the precise degree of compression and allows for adjustment if the compression intensity is too weak or too strong. This enables the cardiopulmonary resuscitation practitioner to maintain an appropriate compression force.

[0075] A 6-axis inertial sensor (53) is positioned between the pressure sensor (52) and the circuit unit (51). The 6-axis inertial sensor (53) is electrically connected to the circuit unit (51). The 6-axis inertial sensor (53) is arranged along the circumferential direction relative to the pressure sensor (52). The 6-axis inertial sensor (53) is positioned adjacent to the pressure sensor (52) to detect the movements and posture of the person performing cardiopulmonary resuscitation. Through this, not only the applied pressure but also the position and movement of the hand can be tracked. By accurately measuring the depth, direction, and speed of compressions while performing cardiopulmonary resuscitation, it is possible to maintain proper cardiopulmonary resuscitation.

[0076] Accordingly, according to the present embodiment, the pressure sensor (52) and the 6-axis inertial sensor (53) detect the intensity, position, and movement of the compression in real time and provide feedback, thereby enabling accurate cardiopulmonary resuscitation.

[0077] In addition, it enables the precise maintenance of compression intensity and speed, thereby maximizing the effectiveness of cardiopulmonary resuscitation and increasing the chances of saving a life.

[0078] In addition, the control unit and sensors work in conjunction to provide a function that automatically detects, warns of, or adjusts incorrect CPR movements, thereby enabling even non-experts to perform effective CPR.

[0079] Meanwhile, the cardiopulmonary resuscitation assistance device (3) according to the present embodiment may further include a display unit (54).

[0080] The display unit (54) is positioned on one side of the main body (20). The display unit (54) has a flexible structure and can display videos related to cardiopulmonary resuscitation, videos explaining the use of the cardiopulmonary resuscitation assistance device (3), etc. The display unit (54) can be electrically connected to the control unit (50). Video education can be conducted through the display unit (54).

[0081] Other configurations may be applied as they are from the embodiments of FIGS. 1 to 6.

[0082] Next, another embodiment of the present invention will be described with reference to FIG. 9.

[0083] Referring to FIG. 9, the cardiopulmonary resuscitation assistance device (4) according to the present embodiment has most of the components of the embodiment described with reference to FIG. 1 to FIG. 8, and further includes a seat member (70).

[0084] The sheet member (70) is combined with the rear surface (20a). The sheet member (70) can be made of materials such as silver foil or vinyl. That is, the sheet member (70) can be made of a material that can block the flow of air. Accordingly, the sheet member (70) traps the body heat of the person undergoing cardiopulmonary resuscitation so that the body temperature does not drop.

[0085] Additionally, a heating wire (71) is formed in the sheet member (70). The heating wire (71) is electrically connected to the control unit (50). The heating wire (71) can generate heat through the power supply of the control unit (50). Accordingly, a preset amount of heat can be generated in the sheet member (70). The sheet member (70) can achieve a warm state while maintaining the body temperature of the cardiopulmonary resuscitation subject through the heating of the heating wire (71).

[0086] The sheet member (70) can maintain the body temperature of the cardiopulmonary resuscitation subject to provide warmth. Depending on the condition of the cardiopulmonary resuscitation subject, the heating wire adjusts the temperature to provide warmth, thereby allowing cardiopulmonary resuscitation to be performed more effectively.

[0087] Accordingly, according to the present embodiment, a sheet member equipped with a heating function can provide a warm temperature to a CPR subject during CPR. This can prevent a drop in body temperature that the CPR subject may experience during CPR, which is an important effect because a drop in body temperature can pose a life-threatening risk. Maintaining an appropriate body temperature can contribute to increasing the likelihood of recovery for the CPR subject.

[0088] Furthermore, the heating element of the sheet can promote blood circulation by providing a constant temperature. Since patients undergoing cardiopulmonary resuscitation often have poor blood circulation, the vasodilation caused by the heat helps improve blood flow, which can have a positive effect on supplying more oxygen to the heart and other organs.

[0089] Furthermore, since excessively low temperatures can slow the heart rate, the sheet helps the heart function more efficiently by maintaining body temperature at an appropriate level. The heating function of the heating element is effective in providing an optimal environment for the patient during cardiopulmonary resuscitation, thereby facilitating a rapid and normal recovery of the heart.

[0090] Furthermore, patients undergoing cardiopulmonary resuscitation (CPR) may fall into a state of hypothermia, where their body temperature drops rapidly. The heating sheet prevents this and helps to keep the patient's body temperature from falling too quickly during the CPR process. Since hypothermia can hinder recovery, the heating function of the sheet and heating wires can play an important supportive role in treatment.

[0091] Other configurations may be applied as they are from the embodiments of FIGS. 1 to 8.

[0092] Meanwhile, according to another embodiment of the present invention, the control unit (50) may further include a report button, a GPS module for obtaining GPS location information, and a communication module that reports an emergency situation when the report button is pressed.

[0093] When the call button is pressed by the person performing cardiopulmonary resuscitation, the control unit can transmit GPS location information to the emergency situation management center through the communication module. The emergency situation management center receives the GPS location information and dispatches an emergency based on the GPS location information.

[0094] Therefore, it enables a rapid location-based response in the event of an emergency, which can contribute to securing the golden time necessary for saving lives.

[0095] Other configurations may be applied as they are from the embodiments of FIGS. 1 to 9.

[0096] Although preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements by those skilled in the art using the basic concept of the present invention as defined in the following claims also fall within the scope of the present invention.
