Description

CPR training mannequin capable of simulating rib fractures

[0001] The present invention relates to a cardiopulmonary resuscitation training mannequin, and in particular, to a cardiopulmonary resuscitation training mannequin capable of simulating a rib fracture.

[0002]

[0003] The number of patients with pre-hospital cardiac arrest is on the rise due to the aging of the population and the increase in cardiovascular diseases. According to the Korea Disease Control and Prevention Agency's acute cardiac arrest survey statistics, the incidence of acute cardiac arrest in 2022 was 68.3 per 100,000 people, which is higher than that of thyroid cancer (56.8) and lung cancer (56.4), which are classified as major cancers.

[0004] Furthermore, since the rate of acute cardiac arrest occurring in non-public places such as homes (64.5%) is significantly higher than in public places with many witnesses (16.4%), the performance of cardiopulmonary resuscitation by bystanders is of paramount importance.

[0005] However, as the general public lacks knowledge about cardiac arrest and has limited experience learning and practicing cardiopulmonary resuscitation (CPR), the reality is that high-quality CPR is not being performed when actual cardiac arrest occurs.

[0006] Furthermore, the fear of physical injury to cardiac arrest patients resulting from the performance of CPR, such as rib fractures caused by chest compressions, also acts as a major factor limiting the performance of high-quality CPR.

[0007] The CPR training mannequins currently in use have a problem in that they cannot simulate rib fractures caused by chest compressions, which the general public fears, and thus cannot provide an environment similar to actual CPR execution.

[0051] The configuration and operation according to a preferred embodiment of the present invention will be described in detail below with reference to the attached drawings.

[0052] This is intended to provide a detailed explanation sufficient for a person skilled in the art to easily implement the contents of the present invention, and does not imply that the technical concept and scope of the present invention are limited thereby.

[0053] In addition, it should be noted that when assigning reference numerals to the components of each drawing, identical components are denoted by the same numeral whenever possible, even if they are shown in different drawings; furthermore, terms specifically defined in consideration of the structure and operation of the present invention may vary according to the intent or convention of the user or operator, and the definition of such terms should be determined based on the content throughout this specification.

[0054] Furthermore, throughout the specification, when a part is described as "including" a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components.

[0055] FIG. 1 is a perspective view illustrating a rib module (10) of a cardiopulmonary resuscitation training mannequin (1) capable of simulating a rib fracture according to one embodiment of the present invention, FIG. 2 is a detailed enlarged view of the costal cartilage portion (12) connection part of the rib module (10) of FIG. 1, and FIG. 3 is a side cross-sectional view of the rib module (10) of FIG. 1.

[0056] In addition, FIG. 4 is an exploded perspective view of a cardiopulmonary resuscitation training mannequin (1) capable of simulating a rib fracture according to one embodiment of the present invention.

[0057] First, as illustrated in FIG. 4, a cardiopulmonary resuscitation training mannequin (1) according to one embodiment of the present invention is composed of a rib module (10) capable of simulating a rib fracture, a main elastic body (20), and a mannequin body (30).

[0058] The rib module (10) receives cardiopulmonary resuscitation pressure applied by the trainee during cardiopulmonary resuscitation training, and the cardiopulmonary resuscitation pressure received by the rib module (10) downward is elastically supported by the main elastic body (20). Due to the elastic repulsive force of the main elastic body (20), the rib module (10) that is pressed downward moves upward again, enabling repetitive training.

[0059] Here, "downward" refers to the direction in which the trainee applies pressure during cardiopulmonary resuscitation training, and since the cardiopulmonary resuscitation training mannequin (1) is typically laid on the ground during training, it refers to the direction facing the ground. "Upward" refers to the opposite direction of "downward," and unless otherwise specified, it will be referred to in the same way throughout the detailed description of the invention.

[0060] The rib module (10) and the main elastic body (20) are installed inside the mannequin body (30). The mannequin body (30) has a shape similar to the upper body of a human body and is configured by dividing it into a lower body part (301) corresponding to the back of the upper body and an upper body part (302) corresponding to the belly and chest, and the upper body part (302) can be configured to cover the lower body part (301) from above.

[0061]

[0062] If the mannequin body (30) is configured by dividing it, maintenance and management of the rib module (10) and main elastic body (20) installed inside can be facilitated, and in particular, it is also easy to restore the rib module (10) that simulates a rib fracture—that is, a fractured rib module—to its original state.

[0063] The mannequin body (30), particularly the upper body part (302), can be made of a soft material such as rubber or silicone to enhance the realism of cardiopulmonary resuscitation training, and the pressure applied by the cardiopulmonary resuscitation trainee to the cardiopulmonary resuscitation training mannequin (1) can be directly transmitted to the rib module (10).

[0064] The upper body part (302) may be formed integrally with the rib module (10).

[0065] When the cardiopulmonary resuscitation pressure applied by the trainee to the cardiopulmonary resuscitation training mannequin (1) exceeds the pressure that can maintain the rib module (10) without fracture, the rib module (10) fractures, and the trainee can recognize the rib fracture situation.

[0066] The characteristic configuration of the rib module (10) capable of simulating such a rib fracture situation is illustrated in detail in FIGS. 1 to 3.

[0067] Referring to FIGS. 1 to 3, the rib module (10) is composed of a sternal portion (11), a costal cartilage portion (12), and a rib portion (13). The sternal portion (11) is formed by extending in the longitudinal direction with a predetermined width, and one end of the costal cartilage portion (12) is detachably connected to the side of the sternal portion (11). Multiple costal cartilage portions (12) are installed spaced apart from each other along the longitudinal direction of the sternal portion (11).

[0068] Additionally, the other end of each costal cartilage portion (12) is detachably connected to the rib portion (13). The rib portion (13) is formed by extending in a direction that crosses the longitudinal direction in which the sternal portion (11) extends, and is composed of multiple portions like the costal cartilage portion (12).

[0069] The connection between the sternum (11) and the costochondral portion (12) and the connection between the costochondral portion (12) and the rib portion (13) are all implemented in a separable manner, and when the rib module (10) simulates a fracture situation, at least one of these connections between the sternum (11) and the costochondral portion (12) and between the costochondral portion (12) and the rib portion (13) is separated. When these connections are separated, the sternum (11), the costochondral portion (12), and / or the rib portion (13) constituting the rib module (10) are positioned out of alignment with each other, so that a trainee applying cardiopulmonary resuscitation pressure to the rib module (10) can perceive the rib fracture situation tactilely, audibly, and / or visually. Detailed technical configurations regarding the connection between the sternum (11) and the costal cartilage (12) and the connection between the costal cartilage (12) and the rib (13) will be described later.

[0070] A main elastic body (20) is positioned below the sternum (11) to stably support the cardiopulmonary resuscitation pressure received by the rib module (10) in a downward direction. The main elastic body (20) may use a coil spring having a predetermined height and elastic modulus, but is not limited thereto; it is also possible to use other types of springs, such as leaf springs, or pneumatic or hydraulic actuators.

[0071] The main elastic body (20) can be installed with one end fixed to the lower body portion (301) of the mannequin body (30), but it is also possible to install the main elastic body (20) on a separate support plate (40) and fix the support plate (40) to the lower body portion (301).

[0072] When installing the support plate (40), the end of the rib portion (13) that is not connected to the costal cartilage portion (12) can be fixed to the side of the support plate (40) to install it.

[0073] Referring to Fig. 2, the rib fracture simulation mechanism will be explained in detail.

[0074]

[0075] A cardiopulmonary resuscitation training mannequin (1) capable of simulating a rib fracture according to one embodiment of the present invention is provided with a sternal joint (14) that can separately connect the sternal portion (11) and the costal cartilage portion (12), and when a cardiopulmonary resuscitation pressure greater than a predetermined value is applied to the sternal joint (14), the sternal joint (14) separates, thereby separating the sternal portion (11) and the costal cartilage portion (12).

[0076] The sternal joint (14) is implemented as a ball-socket type joint composed of a sternal socket (141) and a sternal ball (142), and is held in close contact by the geometric shape between the ball and the socket and the bonding force due to friction. Additionally, at least one of the sternal socket (141) and the sternal ball (142) can be made of a soft material such as rubber or silicone to double the bonding force.

[0077] A sternal socket (141) is installed on the side of the sternal portion (11), and a sternal ball (142) having a shape complementary to the sternal socket (141) having a concave groove can be installed at one end of the costal cartilage portion (12).

[0078] In this way, by forming the sternal joint (14), the sternal portion (11) and the costal cartilage portion (12) are separatedly connected, thereby enabling the simulation of a rib fracture.

[0079] Meanwhile, as previously observed, the bonding force of the sternal joint (14) is determined by the friction of the surfaces according to the geometric shape and material of the sternal socket (141) and the sternal ball (142).

[0080] In actual cardiac arrest patients undergoing CPR, the pressure required to cause rib fractures varies depending on gender, age, physique, or body weight; if CPR training mannequins can implement such diverse rib fracture models, it becomes possible to provide an environment similar to actual CPR execution.

[0081] To implement this, a magnet that provides an additional coupling force, such as magnetic force, can be installed on the sternal socket (141) and sternal ball (142) of the sternal joint (14).

[0082] More specifically, a sternal electromagnet (143) capable of adjusting the strength of the magnetic force is installed on the inner side of the sternal socket (141), and when the sternal socket (141) and the sternal ball (142) are combined, a sternal permanent magnet (144) is installed at a position on the sternal ball (142) corresponding to the position of the sternal electromagnet (143) installed in the sternal socket (141), thereby allowing the separation strength of the sternal joint (14) to be adjusted by the magnetic force of the sternal electromagnet (143) and the sternal permanent magnet (144). The separation strength of the sternal joint (14) can be achieved by electrically adjusting the strength of the magnetic force of the sternal electromagnet (143).

[0083] Additionally, a sternal rib fracture sensor (145) for detecting separation may be installed in the sternal joint (14). The sternal rib fracture sensor (145) may be a contact sensor and may be installed in the sternal socket (141) and / or the sternal ball (142) to detect when the sternal joint (14) is separated and the connection between the sternal socket (141) and the sternal ball (142) is released. Although an electrical contact sensor was used as the sternal rib fracture sensor (145), it is understood that various sensors, such as infrared sensors, may be used within the scope of the present invention.

[0084] The separation signal detected by the sternal rib fracture sensor (145) can provide a visual notification to the CPR trainee through a display (not shown).

[0085] In a cardiopulmonary resuscitation training mannequin (1) capable of simulating a rib fracture according to one embodiment of the present invention, in addition to a sternal joint (14) that separately connects the sternum (11) and the costal cartilage (12), a rib joint (15) that separately connects the costal cartilage (12) and the rib (13) is further provided, and when a cardiopulmonary resuscitation pressure greater than a predetermined value is applied to the rib joint (15), the rib joint (15) separates, thereby separating the costal cartilage (12) and the rib (13).

[0086] Similar to the sternal joint (14), the rib joint (15) can be implemented as a ball-socket type joint composed of a rib socket (151) and a rib ball (152), and at least one of the rib socket (151) and the rib ball (152) can be made of a soft material such as rubber or silicone.

[0087] A rib-side socket (151) is installed at one end of the rib portion (13), and a rib-side ball (152) having a shape complementary to the rib-side socket (151) having a concave groove can be installed at one end of the costal cartilage portion (12).

[0088] In this way, by forming the rib-side joint (15), the costal cartilage portion (12) and the rib portion (13) are separatedly joined so as to simulate a rib fracture.

[0089] A magnet can be installed to provide additional coupling force, such as magnetic force, to the rib socket (151) and rib ball (152) of the rib joint (15).

[0090] More specifically, a rib-side electromagnet (153) capable of adjusting the strength of the magnetic force is installed on the inner side of the rib-side socket (151), and when the rib-side socket (151) and the rib-side ball (152) are combined, a rib-side permanent magnet (154) is installed at a position on the rib-side ball (152) corresponding to the position of the rib-side electromagnet (153) installed in the rib-side socket (151), thereby allowing the separation strength of the rib-side joint (15) to be adjusted by the magnetic force of the rib-side electromagnet (153) and the rib, i.e., the permanent magnet (154). The separation strength of the rib-side joint (15) can be achieved by electrically adjusting the strength of the magnetic force of the rib-side electromagnet (153).

[0091] Additionally, a rib fracture sensor (155) can be installed in the rib joint (15) on the rib socket (151) and / or rib ball (152) to detect when the rib joint (15) is separated and the connection between the rib socket (151) and the rib ball (152) is released. Of course, various sensors such as an electrical contact sensor or an infrared sensor similar to the sternal rib fracture sensor (145) can be used as the rib fracture sensor (155).

[0092] A separation signal detected from the rib fracture sensor (155) can also be visually notified to the CPR trainee through a display (not shown).

[0093] During CPR training, trainees apply CPR pressure by focusing on the area near the heart, which is where the 3rd to 5th ribs are located, and fractures of the 3rd to 5th ribs frequently occur during actual CPR.

[0094] Accordingly, the rib module (10) of the cardiopulmonary resuscitation training mannequin (1) capable of simulating a rib fracture according to one embodiment of the present invention is divided into a sternal portion (11), a costal cartilage portion (12), and a rib portion (13) to simulate a rib fracture, but the rib module (10) is not divided into all ribs, and the rib module (10) can be configured with a separate configuration of the sternal portion (11), costal cartilage portion (12), and rib portion (13) to the rib module (10) corresponding to the positions of the 3rd to 5th ribs.

[0095] As can be seen in FIG. 1, the ribs located on the upper and lower sides of the rib module (10) are connected as a fixed rib (16) that is not separated and is connected integrally, and only the three ribs corresponding to the positions of the 3rd to 5th ribs may be configured as a divided structure of the sternal portion (11), costochondral portion (12), and rib portion (13).

[0096] A cardiopulmonary resuscitation training mannequin (1) capable of simulating a rib fracture according to one embodiment of the present invention is equipped with a depth measuring sensor (111) to measure the depth to which the rib module (10) moves downward due to cardiopulmonary resuscitation pressure.

[0097] As illustrated in FIG. 3, the depth measuring sensor (111) may be an infrared sensor or a magnetic flux sensor installed on the side of the longitudinal end of the sternum (11), and can measure the depth to which the sternum (11) has moved downward due to cardiopulmonary resuscitation pressure during cardiopulmonary resuscitation training.

[0098] The depth measured by the depth measuring sensor (111) is displayed on the previously described display (not shown) to increase the training accuracy of the trainee.

[0099] In addition, a cardiopulmonary resuscitation training mannequin (1) capable of simulating a rib fracture according to one embodiment of the present invention may support cardiopulmonary resuscitation pressure by placing an auxiliary elastic body (50) below the costal cartilage portion (12) and / or rib portion (13).

[0100] As illustrated in FIGS. 1 and 3, auxiliary elastic bodies (50) may be installed on each side of the main elastic body (20), and each auxiliary elastic body (50) may be composed of an auxiliary support plate (501) and an auxiliary spring (502) for stably supporting a plurality of costal cartilage portions (12) and / or rib portions (13) by contacting them. In this case, a plurality of auxiliary springs (502) may be placed below the auxiliary support plate (501). The auxiliary elastic body (50) may be fixed to the support plate (40) or installed on the lower body portion (301), just like the main elastic body (20).

[0101] If the elastic modulus of the main elastic body (20) and the auxiliary elastic body (50) are configured to be different from each other, or if the height from the lower fixed position of the main elastic body (20) and the auxiliary elastic body (50) is configured to be different from each other, the pressure applied to the sternum (11), costochondral (12), and rib (13) of the rib module (10) is varied, making it easier to simulate a rib fracture situation.

[0102] As described above, the detailed description of the present invention has explained specific embodiments, but it is understood that various modifications are possible within the scope of the described content. Therefore, the scope of the described content does not need to be limited to the described embodiments, but should be defined by the claims set forth below as well as equivalents thereof.
