Description

Technical Field

[0001] The present invention relates to the simulation and testing of cardiopulmonary resuscitation (CPR) pressing effects. Specifically, the present invention relates to a human thoracic cavity CPR simulator and a simulation device and a mannequin including the human thoracic cavity CPR simulator. Background Art

[0002] Cardiac arrest refers to the sudden cessation of the heart's ejection function, resulting in the interruption of systemic blood circulation, respiratory arrest, and loss of consciousness. According to relevant statistical data, about 1.8 million people die of sudden death in China every year, and 72%-80% of them are out-of-hospital sudden deaths. Therefore, timely and effective CPR is the first link for patients with sudden heart attacks to survive. The best time for rescue is within 4 minutes after cardiac arrest. If waiting for doctors or rescue personnel to arrive outside the hospital, it is often too late. Traditional CPR mainly uses the method of external chest manual pressing (rarely direct cardiac compression during open chest surgery), but this method is prone to problems such as pressing fatigue, inconsistent pressing force, and irregular pressing rhythm. Especially when long-term pressing is required, it is easy to reduce the success rate of patient rescue, and incorrect operation techniques are likely to cause damage to the patient's sternum. It is urgent to equip electric CPR devices in public places, places with large passenger flows, and places such as hospitals that require first aid means.

[0003] The cardiopulmonary resuscitation machines widely used in the current market can be roughly divided into three categories. The first category of products is based on the heart pump theory mechanism and directly presses on the sternum outside the heart to achieve the effect of pressing the heart at a single point, so as to make the heart pump blood. The application of the first category of products can refer to a device for patient resuscitation disclosed in the patent application document US20120238922A1, which uses a plunger drive device with single-point pressing to press on the human chest cavity. Based on the requirements of the pressing effect, the pressing depth must reach 50 mm, which easily breaks the chest ribs in the human chest cavity. The second category of products is based on the chest pump theory mechanism and squeezes the entire chest of the patient to achieve heart pumping through the internal squeezing of the chest cavity. The application of the second category of products can refer to the automated chest compression device disclosed in the patent application document CN108430427A, whose feature is to squeeze the chest cavity through the contraction of the bandage to achieve better cardiopulmonary resuscitation. In actual application, it is found that there is a risk of easily breaking the ribs on both sides of the chest cavity when using the second category of products. The third category of products combines the heart pump theory mechanism and the chest pump theory mechanism, including both single-point pressing and squeezing of the chest cavity. The application of the second category of products can refer to the chest compression device disclosed in the patent application document US7060041B1. The technical feature of this device is that there is both pressing, and at the same time, the bandage will produce squeezing on the chest cavity during pressing, causing the chest cavity to contract as a whole while the chest cavity is being pressed down as a whole. The effect of chest cavity contraction is better (better blood perfusion effect, coronary perfusion pressure index), and the damage to the human body is small (equivalent to wrapping the human body, from single-point pressing to multi-point wrapping pressure).

[0004] In the field of cardiopulmonary resuscitation, there are three major indicators for detecting the quality of cardiopulmonary resuscitation effects, namely coronary perfusion pressure (CPP), arterial diastolic pressure, and end-tidal carbon dioxide concentration (ETCO2). To achieve these indicators, high-quality cardiopulmonary resuscitation operations need to be performed by a cardiopulmonary resuscitation machine during external chest compressions to increase the chance of the patient's survival. Therefore, how to conduct performance testing and performance research on cardiopulmonary resuscitation machine products is very important. With the development of science and technology and continuous research in the field of cardiopulmonary resuscitation, cardiopulmonary resuscitation machine products are constantly iterating and updating, and the testing equipment for testing and researching cardiopulmonary resuscitation machine products is also constantly updated. Currently, there are a wide variety of cardiopulmonary resuscitation machine products, and the cardiopulmonary resuscitation effects are uneven. A relatively reliable method is needed to conduct performance testing and performance research on cardiopulmonary resuscitation machine products. Most of the current testing equipment for cardiopulmonary resuscitation machine products only tests single-point pressing parameters and cannot meet the testing of diverse cardiopulmonary resuscitation machine products; especially for the research and testing of the above-mentioned third category of products, it is difficult to directly and effectively obtain the cardiopulmonary resuscitation effects of such products by existing technical means.

[0005] In view of this, it is necessary to redesign and develop a tool that can simulate the actual situation of the human chest cavity to cooperate with obtaining test data on the cardiopulmonary resuscitation effect intuitively and effectively. Summary of the Invention

[0006] In a first aspect, the present invention provides a human chest cavity cardiopulmonary resuscitation simulator for observing and detecting the use effect of a cardiopulmonary resuscitator.

[0007] A human chest cavity cardiopulmonary resuscitation simulator, the simulator includes a moving part and an elastic part, wherein:

[0008] The moving part is a structure that moves after receiving an external pressing force or squeezing force, and a plurality of moving parts are arranged around a central area; each moving part can move closer to or away from the central area along its respective moving path when receiving an external pressing force or squeezing force, and the moving paths of all the moving parts are radially arranged around the central area; and each of the moving parts has a cut-off end point at one end of its moving path away from the central area for restricting the moving range of the moving part.

[0009] The elastic part is a structure that provides an elastic force acting away from the central area to the moving part; the elastic part acts elastically on the moving part, and in the initial state, the moving part abuts against the cut-off end point under the elastic force of the elastic part.

[0010] In a second aspect, the present invention provides a simulation device with a simulator, including a cardiopulmonary resuscitator and the human chest cavity cardiopulmonary resuscitation simulator described in the first aspect, and the cardiopulmonary resuscitator includes a machine head and a bandage, and the bandage is wrapped around the outside of the moving and contracting part in a circle.

[0011] In a third aspect, the present invention provides a simulation man, and the human chest cavity cardiopulmonary resuscitation simulator described in the first aspect is provided in the simulation man.

[0012] The further description of the relevant content of the present invention is as follows:

[0013] 1. By implementing the above technical solutions of the present invention, in the simulator of the present invention, through the arrangement of the moving parts, the simulator can provide a contour that can perfectly simulate the human chest cavity. The setting of its moving path and the setting of the moving range limit can accurately and intuitively simulate the changes of the human chest cavity when being pressed and squeezed. The elastic part is used to provide an elastic force acting away from the central area for the moving part, and it is also used to simulate the elasticity of human tissues when the human chest cavity contracts downward and inward when being pressed and squeezed, as well as the acting force and the simulation with an expansion range when the human chest cavity expands when the pressing and squeezing are released. Compared with the existing conventional single-point pressing test equipment, the simulator of the present invention can visually, reliably and effectively display and simulate the multi-directional cardiopulmonary resuscitation pressing effect of the human chest cavity. Through the direct observation of the moving part, the contraction of the human chest cavity can be intuitively reflected, such as the overall contraction amplitude of the chest cavity and the contraction amplitudes at different positions of the chest cavity. Information such as the displacement, acceleration and force of several structures can also be obtained through testing means to form more effective and reliable test parameters.

[0014] 2. In the technical solution of the first aspect above, define the vertical direction of the chest cavity contour when the human body is lying supine as the up and down direction, and define the direction from head to toe when the human body is lying supine as the front and back direction. The simulator is used to simulate the contour of the human chest cavity or to present an annular shape (such as a circle, an ellipse, etc.), and at least includes one moving part located above the top, and at least two moving parts located on both sides below the top. In one case, the moving part located at the top is used to bear the pressing force of the pressing machine, and the moving parts located on both sides are used to bear the squeezing force of the linkage bandage. This setting can form a relatively simple contour of the human chest cavity.

[0015] 3. In the technical solution of the first aspect above, the elastic parts are arranged to act on each moving part separately. One moving part is jointly acted on by multiple elastic parts to provide elastic displacement when it changes between the telescopic state and the unfolded state. For example, one moving part can correspond to two, three or even more elastic parts to provide elastic support.

[0016] 4. In the technical solution of the first aspect above, in the initial state, all the moving parts are distributed around a toroidal surface or a toroidal contour, where:

[0017] When the moving parts are distributed around a toroidal surface, the toroidal surface is an elliptical cylinder, a cylinder or a contour shape simulating the human chest cavity;

[0018] When the moving parts are distributed around a toroidal contour, the toroidal contour is an ellipse, a circle or a contour shape simulating the cross-section of the human chest cavity.

[0019] 5. In the technical solution of the above first aspect, each of the moving parts is provided with a contact surface for bearing an external pressing force or squeezing force, and the component applying the external pressing force or squeezing force fits various shape changes of the contacted part in an adaptive manner with the contact surface of at least one moving part. At least one of the moving parts can rotate about a rotation axis perpendicular to its moving path and substantially parallel to the central region, so as to better simulate different shape changes formed by the human chest cavity when subjected to forces in different directions and magnitudes.

[0020] 6. In the technical solution of the above first aspect, when each of the moving parts bears an external pressing force or squeezing force and moves closer to or away from the central region along its respective moving path, according to the difference in the external pressing force or squeezing force borne or the difference in the elastic acting force of the elastic part, each of the moving parts has a different moving distance.

[0021] 7. In the technical solution of the above first aspect, the simulator further includes a guiding and supporting part, and the guiding and supporting part is a mechanism for restricting the moving path of the moving part. One end of the elastic part acts on the moving part and the other end acts on the guiding and supporting part. In one case, the guiding and supporting part includes a central block located in the central region and guiding columns positioned and installed on the central block and extending in the direction of the moving path; in another case, the guiding and supporting part includes an inner frame surrounding the inside of the moving part, guiding columns are arranged on the periphery of the inner frame, and the elastic part is sleeved on the guiding columns, and the direction of the elastic action applied by the elastic part to the moving part is the direction in which the guiding columns face outwards; in still another case, the guiding and supporting part includes an outer frame surrounding the outside of the moving part, guiding columns facing the inside of the central region are arranged on the inner wall of the outer frame, the elastic part is a tension spring, the elastic part is sleeved on the guiding columns, and the direction of the elastic action applied by the elastic part to the moving part is the direction in which the guiding columns face outwards.

[0022] 8. In the technical solution of the above first aspect, the simulator further includes a data acquisition part, and the data acquisition part is arranged at at least one corresponding position among the moving part, the elastic part, and the guiding and supporting part. The data acquisition part is configured to acquire data information when the moving part moves along the moving path. The data acquisition part includes one or more of a distance measuring sensor, a motion sensor, and a force sensor. The data information acquired by the data acquisition part includes at least one or more of the following data: the displacement data of the moving part, the force data of the moving part, the relative displacement data between the moving part and the guiding and supporting part, and the force data of the elastic part; in one case, the moving part has an observed surface facing forward or backward, the data acquisition part is a visual acquisition unit, and the visual acquisition unit acquires continuous / intermittent image information of the observed surface, and then extracts the image information, or the change situation can also be directly observed by the human eye.

[0023] 9. In the technical solution of the above first aspect, at least two adjacent moving parts are hinged by a shaft, and a sliding connection structure is provided on at least one of the two adjacent moving parts hinged by the shaft, so that at least one of the moving parts hinged by the shaft has a degree of freedom of movement in a direction perpendicular to the moving path of the moving part approaching or departing from the central area; in another way, at least two adjacent moving parts are flexibly connected by a flexible material; in this way, the situation on the side of the human chest cavity can be simulated more realistically.

[0024] 10. In the technical solution of the above first aspect, the elastic coefficients of all elastic parts are the same, and it can be inferred which position receives a greater pressing force when the pressing machine acts on the human body; the elastic coefficients of each elastic part can also be set differently, so that the elastic coefficient of each elastic part corresponds to different parts of the human body; it is also possible to make the elastic coefficient of the elastic part located in the front greater than the elastic coefficient of the elastic part located in the rear to simulate the actual situation that the ribs in the front are lower than the ribs in the rear when the human body is lying on its back.

[0025] 11.

For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium. It can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0026] 12. In the present invention, the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "axial direction", "bottom", "inner", "outer", etc. is the orientation or positional assembly relationship based on the orientation or position shown in the drawings. It is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to this application.

[0027] 13. In addition, terms such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first", "second" may explicitly or implicitly include at least one of the features.

[0028] The present invention provides several advantages over the prior art, and the several advantages include:

[0029] 1. In some embodiments, through the arrangement of the moving part, the simulator can provide a contour that can perfectly simulate the human chest cavity. The setting of its moving path and the setting of the moving range limit can accurately and intuitively simulate the changes of the human chest cavity when it is pressed or squeezed. The elastic part is used to provide an elastic force for the moving part that points away from the central area. It is also used to simulate the elasticity of human tissues when the human chest cavity contracts downward and inward when pressed or squeezed, as well as the acting force and the simulation with an expansion range when the human chest cavity expands when the pressing or squeezing is released. Compared with the existing conventional single-point pressing test equipment, the simulator of the present invention can visually, reliably and effectively display and simulate the multi-directional cardiopulmonary resuscitation pressing effect of the human chest cavity.

[0030] 2. In some embodiments, the simulator in the technical solution of the present invention can directly observe the moving part and can intuitively reflect the contraction of the human chest cavity, such as the overall contraction amplitude of the chest cavity and the contraction amplitudes at different positions of the chest cavity, so as to visually and reliably show the most intuitive contraction of the simulated human chest cavity when it is subjected to pressing force or squeezing force.

[0031] 3. The test tooling of the prior art is used for single-point pressing tests, while the above technical solution of the present invention takes into account that if a pressing machine plus a bandage is used, it will cause multi-directional pressing on the human chest cavity, maximizing the simulation effect of the simulator when the human chest cavity is subjected to multi-point pressing / squeezing, which is stable and reliable.

[0078] To make the above objects, features and advantages of the present application more obvious and understandable, the following detailed description of the specific implementation manners of the present application will be given with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific implementation manners disclosed below.

[0079] The present invention aims to be able to intuitively reflect the contraction situation of the human chest cavity, including the overall contraction amplitude of the chest cavity and the contraction amplitudes at different positions of the chest cavity, as well as other parameters during the cardiopulmonary resuscitation process of the human body, by observing and detecting the changes in parameters such as the displacement of the acting components in the simulator. Thus, the contraction situations of various pressing machines with bandages on the market can be tested.

[0080] An important feature of the present invention is its ability to simulate the contraction amplitudes and other parameters at different positions of the human chest cavity. Essentially, the bandage and the pressing head provide effective pressure to the simulator, thereby obtaining a better and more realistic contraction situation. At the same time, the simulator itself can find the equilibrium position for better contact. This is particularly advantageous when considering the variability of the shape of the human chest cavity tissue and the need for better engagement for more effective and accurate testing. At the same time, the vertical direction of the chest cavity contour when the human body is lying supine is defined as the up and down direction, and the direction from head to foot when the human body is lying supine is defined as the front and back direction.

[0081] A human chest cardiopulmonary resuscitation simulator of the present invention is used for simulating and testing when a cardiopulmonary resuscitation machine or a mannequin applies external pressing force and squeezing force to the simulator, and is particularly applicable to observing and detecting the use effect of a cardiopulmonary resuscitation machine. The simulator includes a moving part 1 and an elastic part 2. The moving part 1 is a structure that moves after bearing external pressing force or squeezing force. A plurality of moving parts 1 are arranged around a central area 101. When each moving part 1 bears external pressing force or squeezing force, it can approach or move away from the central area 101 along its respective moving path. The moving paths of all the moving parts 1 are radially arranged around the central area 101. And each moving part 1 has a cut-off end point at one end of its moving path away from the central area 101 for restricting the moving range of the moving part 1. The elastic part 2 is a structure for providing an elastic force acting away from the central area 101 to the moving part 1. The elastic part 2 elastically acts on the moving part 1. In the initial state, the moving part 1 abuts against the cut-off end point under the elastic force of the elastic part 2.

[0082] In the above technical solution, the external pressing force or squeezing force can be generated by the pressing head 61 and the bandage 62 in the cardiopulmonary resuscitation machine 6. Taking the example that the human chest cardiopulmonary resuscitation simulator includes at least one moving part 1 at the top and at least two moving parts 1 on both sides below the top, the pressing head 61 in the cardiopulmonary resuscitation machine 6 is installed at the moving part at the top, and the bandage 62 is wrapped around the moving parts on both sides or other parts. When the pressing head 61 applies pressing force, the pressing head 61 drives the bandage 62 to apply a certain pressing force and squeezing force to the moving part. It can also be generated by the pressing force or squeezing force received by the mannequin during cardiopulmonary resuscitation operation. The central area 101 can be regarded as an area for simulating the main part in the human chest that bears the actual squeezing effect or the central part of the human chest. The central area 101 is generally located at the internal center of the simulator. The cut-off end point is a limiting point for restricting the moving range of the moving part 1. The cut-off end point can be regarded as the natural relaxation state of human tissues when no cardiopulmonary resuscitation pressing operation is performed, and the human chest naturally supports and expands. The cut-off end point can be limited by a limiting structure 5, and the specific structure can refer to the embodiments disclosed below.

[0083] In each embodiment of the present invention, the simulator has an initial state and a contracted state. The simulator of the present invention will be described below in combination with the two use states of the simulator:

[0084] Initial state

[0085] In the initial state, the simulator is not subject to external pressing force or squeezing force. At this time, the moving part 1 is not subject to external pressing force and / or squeezing force. Under the action of the elastic part 2, the elastic part 2 presses or pulls the moving part 1 to this cut-off end point. The moving part 1 is constrained by the elastic part 2 and the cut-off end point, and presents a position located away from the central region 101 and at the farthest point.

[0086] Contracted state

[0087] In the contracted state, for example, the simulator can be sleeved on a cardiopulmonary resuscitation machine or a mannequin. When an external pressing force and / or squeezing force is applied to the simulator, each moving part 1, under the combined action of the pressing force and / or squeezing force and the elastic force of the elastic part 2, approaches the central region 101 along the moving path. At this time, the moving part 1 is in a contracted state and presents a position located near the proximal end of the central region 101; during the application and release of the pressing force and / or squeezing force, the simulator will have a process of transitioning from the contracted state to the initial state. At this time, the moving part 1 is located at an intermediate position between the cut-off end point and the trend of approaching or departing from the central region 101.

[0088] When the simulator presents the initial state, all the moving parts 1 are distributed around a toroidal surface or a toroidal contour. When the moving part 1 is distributed around a toroidal surface, the toroidal surface is in the shape of an elliptical cylinder, a cylinder, or the contour of a human chest cavity. When the toroidal surface is in the shape of an elliptical cylinder, the elliptical cylinder toroidal surface means that it is divided into an infinite number of elliptical cross-sections along an axial direction, and the infinite number of ellipses form a continuous and smooth toroidal surface along this axis; the cylindrical toroidal surface means that it is divided into an infinite number of circular cross-sections along an axial direction, and the infinite number of circles form a continuous and smooth toroidal surface along this axis; the contour shape of the human chest cavity means that the moving part 1 is arranged in a curved surface shape similar to the contour structure of the human chest cavity according to the shape of the human chest cavity; when the moving part 1 is distributed around a toroidal contour, the toroidal contour is in the shape of an ellipse, a circle, or the contour of a cross-section of a human chest cavity.

[0089] Taking the simulator having a moving part 1, an elastic part 2, a guiding and supporting part 3, and a set of data acquisition parts 4 as an example, as described in the following embodiments, in order to arrange the moving part 1 and the elastic part 2 on the human chest cardiopulmonary resuscitation simulator, various embodiments of the present invention include:

[0095] 6. A device having a plurality of moving parts 1, elastic parts 2, guiding and supporting parts 3 and a set of data acquisition parts 4, with the guiding and supporting located in the outer frame 34;

[0096] 7. And various other possible embodiments.

[0097] Considering the specific embodiments of the present invention, and the first embodiment is shown in Figures 1A to 1G as follows.

[0098] The first embodiment

[0099] Herein, as Figures 1A to 1J shown, the first embodiment is provided. The human chest cavity cardiopulmonary resuscitation simulator in the first embodiment includes a moving part 1, an elastic part 2, and a guiding and supporting part 3 surrounding according to the contour of the human chest cavity. The guiding and supporting part 3 includes a central block 31 located in the central area 101 and a guiding column 32 positioned and installed on the central block 31 and extending in the direction of the moving part 1;

[0100] The moving part 1 is used to closely adhere to the bandage or the pressing head of the cardiopulmonary resuscitation machine and is used to simulate the human chest cavity. The human chest cavity cardiopulmonary resuscitation simulator at least includes one moving part 1 located at the top and at least two moving parts 1 located on both sides below the top. The moving parts 1 are arranged around the contour of the human chest cavity or the central area 101, and the internal position of the contour is defined as the central area 101. The moving parts 1 contract towards the inside of the central area 101. Each of the moving parts 1 has a cut-off end point for restricting the moving range of the moving part 1 at one end of its moving path away from the central area 101. The cut-off end point is a limiting mechanism provided at the top of the guide post 32, and the limiting mechanism restricts the moving range of the moving part 1 moving outwards. The limiting mechanism includes a linear bearing 51 sleeved on the guide post 32 and slidable along the guide post 32 and a fixing nut 52 sleeved and fixed on the top of the guide post 32. The moving part 1 is assembled to the linear bearing 51. The linear bearing 51 has a limiting part for limiting the moving part 1 away from the central area 101, and the fixing nut 52 has a limiting surface for limiting cooperation with the limiting part. However, the present invention is not limited thereto. The limiting direction can be guided by the axial direction of the guide post 32. At the same time, it should be understood that other structures that can realize the movement limit of the moving part 1 are all equivalent replacements of the limiting structure 5.

[0101] The elastic part 2 is configured to provide at least an elastic displacement for the moving part 1 when it changes between the contracted state and the initial state. In one case, the elastic part 2 can also be used to measure the force applied.

[0102] The guiding and supporting part 3 is used to provide guiding and supporting functions for the moving part 1 during contraction and expansion. When contracting, it guides towards the inside of the central area 101, and when expanding, it guides towards the outside of the central area 101.

[0103] The data acquisition unit 4 is arranged at at least one corresponding position of the moving unit 1, the elastic unit 2, and the guiding and supporting unit 3, and the data acquisition unit 4 is configured to acquire various data information when the moving unit 1 moves along the moving path. The data acquisition unit 4 includes one or more of a distance measuring sensor, a motion sensor, and a force sensor; the data information acquired by the data acquisition unit 4 includes at least one or more of the following data: the displacement data of the moving unit 1, the force data of the moving unit 1, the relative displacement data between the moving unit 1 and the guiding and supporting unit 3, and the force data of the elastic unit 2. The data acquisition unit 4 can be installed on the moving unit 1, or can be installed on the elastic unit 2 or the guiding and supporting unit 3. The simulator can directly observe the moving unit, and can intuitively reflect the contraction of the human chest cavity, such as the overall contraction amplitude of the chest cavity and the contraction amplitude at different positions of the chest cavity, so as to intuitively and reliably show the most intuitive contraction of the simulated human chest cavity when subjected to pressing force or squeezing force. Collecting the above various data can quantify the contraction of the simulator during cardiopulmonary resuscitation of the human chest cavity, and is conducive to data processing for further research.
