Description

Technical Field

[0001] This invention relates to the field of bionic head and neck teaching aids, and more particularly to a bionic head and neck teaching aid. Background Technology

[0002] Opening the airway to maintain a clear airway is the first step in performing artificial respiration. Properly opening the airway is crucial for the successful execution of emergency care in critical moments.

[0003] Currently, there is still a lack of simulated open airway models in medicine. Existing head and neck models for other purposes usually connect the skull and spine via a biaxial connection. This biaxial connection cannot accurately represent head movements or accurately achieve the airway opening angle. The head tilt angle and head tilt angle of these models are too large, which cannot simulate the real airway opening situation. Summary of the Invention

[0004] The main objective of this invention is to provide a bionic head and neck teaching aid that aims to simulate the open airway in actual situations in order to improve teaching effectiveness.

[0005] To achieve the above objectives, this invention proposes a bionic head and neck teaching aid, comprising:

[0006] skull;

[0007] Spine; and

[0008] A linkage assembly, one end of which is connected to the skull via a fastener, and the other end of which is connected to the spine via a frame.

[0009] Optionally, the linkage assembly includes a first linkage and a second linkage, one end of the first linkage is rotatably connected to the fixing member, the other end of the first linkage is rotatably connected to the frame, one end of the second linkage is rotatably connected to the fixing member, and the other end of the second linkage is rotatably connected to the frame.

[0010] Optionally, the frame is provided with a limiting part to limit the rotation range of the second link.

[0011] Optionally, the skull may be tilted back 20° relative to the spine.

[0012] Optionally, the limiting part is a limiting post, which is located in the middle of the frame and below the first connecting rod.

[0013] Optionally, the first link is arranged in an arc shape.

[0014] Optionally, the second link is configured in a V-shape.

[0015] Optionally, the fastener is arranged in a triangular shape; the frame is arranged in a triangular shape.

[0016] Optionally, one end of the first connecting rod is rotatably connected to the fixing member via a first rotating shaft, and the other end of the first connecting rod is rotatably connected to the frame via a second rotating shaft;

[0017] One end of the second connecting rod is rotatably connected to the fixed component via a third rotating shaft, and the other end of the second connecting rod is rotatably connected to the frame via a fourth rotating shaft.

[0018] Optionally, the line connecting the center points of the first rotating shaft and the third rotating shaft is parallel to the side of the fixing member, and the line connecting the center points of the second rotating shaft and the fourth rotating shaft is parallel to the side of the frame.

[0019] In the technical solution of this invention, the bionic head and neck teaching aid includes a skull, a spine, and a connecting rod assembly. One end of the connecting rod assembly is connected to the skull via a fixing member, and the other end of the connecting rod assembly is connected to the spine via a frame. This fills the gap in bionic head and neck teaching aids that simulate the movement trajectory of the head and neck in an open airway, realizes the simulation of an open airway in actual situations, and improves teaching effectiveness.

[0029] This invention proposes a biomimetic head and neck teaching aid.

[0030] refer to Figure 1 and Figure 2 In one embodiment of the present invention, the bionic head and neck teaching aid includes a skull 10, a spine 20 and a connecting rod assembly 30; one end of the connecting rod assembly 30 is connected to the skull 10 through a fixing member 40, and the other end of the connecting rod assembly 30 is connected to the spine 20 through a frame 50.

[0031] In this embodiment, the fastener 40 and the skull 10 can be connected by welding, snap-fitting, threaded connection, hinge or adhesive, and the frame 50 and the spine 20 can also be connected by welding, snap-fitting, threaded connection, hinge or adhesive, etc., without specific limitations.

[0032] In order to enable the skull 10 to tilt backward, in this embodiment, the connecting rod assembly 30 and the fixing member 40 can be connected by means of rotating shaft or hinge, etc. The connecting rod assembly 30 and the frame 50 can also be connected by means of rotating shaft or hinge, etc. The specific connection structure is not limited here.

[0033] It is understood that this invention connects one end of the linkage assembly 30 to the skull 10 via the fixing member 40, and the other end of the linkage assembly 30 to the spine 20 via the frame 50. In this way, it fills the gap in bionic head and neck teaching aids that simulate the movement trajectory of the head and neck in an open airway, realizes the simulation of an open airway in actual situations, and improves teaching effectiveness.

[0034] Analysis of head movements during airway opening revealed that when the head rotates approximately 20 degrees from a natural position to an open airway position, the occipital fulcrum shifts by about 6 cm. This head rotation and fulcrum change indicate that applying downward and backward torque to the forehead is more conducive to airway opening; applying downward force to the head is more conducive to maintaining an open airway. When the airway is open, because the posterior fulcrum of the head and the back are on the same plane, the cervical spine is in a forward flexion position. Applying force from the top of the head towards the soles of the feet at this time is more conducive to opening and maintaining an open airway.

[0035] In response, this invention further improves the bionic head and neck teaching aid to simulate the following when the human head rotates 20 degrees: the top of the head retracts by 2cm, the occipital fulcrum moves downward by 6cm, and the neck flexes forward.

[0036] Please combine Figure 1 and Figure 2 In one embodiment, the linkage assembly 30 may include a first linkage 31 and a second linkage 32 disposed opposite to the first linkage 31. One end of the first linkage 31 is rotatably connected to the fixing member 40, and the other end of the first linkage 31 is rotatably connected to the frame 50. One end of the second linkage 32 is rotatably connected to the fixing member 40, and the other end of the second linkage 32 is rotatably connected to the frame 50. This further enhances the realism of the simulated airway opening, thereby improving the teaching effect.

[0037] In this embodiment, a limiting part 51 may be provided on the frame 50 to limit the rotation range of the second connecting rod 32. The limiting part 51 may be a limiting post or a limiting block, etc., and the limiting part 51 protrudes from the middle of the frame 50 and is located on the lower side of the first connecting rod 31.

[0038] The first connecting rod 31 can be arranged in an arc shape, the second connecting rod 32 can be arranged in a V shape, the fixing component 40 can be arranged in a triangle shape, and the frame 50 can be arranged in a triangle shape. This simplifies the structure of each component of the bionic head and neck teaching aid, making it easier to manufacture.

[0039] Further, mainly refer to Figure 2 One end of the first connecting rod 31 is rotatably connected to the fixing member 40 via the first rotating shaft 301, and the other end of the first connecting rod 31 is rotatably connected to the frame 50 via the second rotating shaft 302; one end of the second connecting rod 32 is rotatably connected to the fixing member 40 via the third rotating shaft 303, and the other end of the second connecting rod 32 is rotatably connected to the frame 50 via the fourth rotating shaft 304.

[0040] In this embodiment, the line connecting the center points of the first rotating shaft 301 and the third rotating shaft 303 is parallel to the side of the fixing member 40 (i.e., Figure 1 The top edge of the fixing member 40 shown is provided, and the line connecting the center points of the second rotating shaft 302 and the fourth rotating shaft 304 is parallel to the side edge of the frame 50 (i.e., Figure 1 The fastener 40 shown is set with its beveled edge.

[0041] When using this bionic head and neck teaching aid, when the head is subjected to a downward force, the first connecting rod 31 rotates around the second rotating shaft 302, and the second connecting rod 32 rotates around the fourth rotating shaft 304. Simultaneously, this causes the fixing member 40 to move upward, tilting the skull 10 backward until the end of the first connecting rod 31 moves to a position contacting the limiting part 51, thus constraining the skull 10 to rotate 20° (i.e., Figure 2 (The included angle α is shown). During this period, the top of the head retracts by 2cm, the occipital fulcrum shifts by 6cm, and the neck flexes forward. Therefore, this bionic head and neck teaching aid simulates the effects of cervical flexion, skull tilting downward and backward, and mandible protrusion when the airway is open, which is completely consistent with the experimental results.

[0042] Furthermore, during the actual process of airway opening, sliding friction occurs due to the relative displacement between the back of the head and the bed surface. The coefficient of friction of human hair is only about 0.016, making it difficult to perceive friction during clinical airway opening procedures.

[0043] To simulate this low-friction effect, a roller structure or a wig can be installed at the bottom of the skull 10 of the bionic head and neck teaching aid where it contacts the bed surface, in order to reduce friction and more realistically reproduce the clinical experience.

[0044] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
