[0002] The chest is one of the most important parts of the human body, containing several vital organs, including the heart. For injuries affecting the internal organs of the chest, open surgery is often chosen when necessary. For example, in a cardiac surgery ICU, patients undergoing open-chest surgery experience significant trauma and severe postoperative pain. After open-chest surgery, patients need to avoid strenuous upper limb movements, especially large-amplitude movements such as chest expansion exercises. In emergency situations such as on-site first aid, the emergency room, or in an ambulance, it is necessary to stabilize the patient's chest wall (sternum, ribs), reduce pain, prevent secondary injury, and improve breathing. Therefore, patients often require immobilization devices to reduce subsequent secondary injuries.

[0003] However, the existing fixation devices are not very flexible and cannot adjust the support effect on the torso and chest as needed. They are also prone to fitting too tightly to the chest, which can lead to displacement, affecting the user experience and the fixation and protection effect.

Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.

[0038] To keep the drawings concise, each drawing only schematically shows the parts relevant to the application; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0041] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0042] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0043] In this embodiment, a fixation device for chest trauma is described. Through the cooperation of the device body, the installation and fixation mechanism and the adjustment mechanism, the fixation device can be stably worn on the user, while also effectively improving the comfort of wearing it and reducing the possibility of secondary injury to the user.

[0044] For details, please refer to the instruction manual appendix. Figures 1 to 3 A fixation device for chest trauma includes a device body, an installation and fixation mechanism, and an adjustment mechanism. The device body allows it to wrap around and conform to the outside of the chest of the human torso, forming a closed fixation structure. This allows the device body to be worn openably on the user, thus providing fixation to the user's chest.

[0045] Correspondingly, the adjustment mechanism, located on the main body of the device, consists of an inflatable airbag assembly and a support assembly. The support assembly is detachably mounted on the main body, allowing it to be easily installed or removed as needed to support the device and adjust its support effect on the patient's torso and chest. The inflatable airbag assembly adjusts the fit between the device and the user by inflating and deflating the airbag. Additionally, the mounting and fixing mechanism, located on the main body, stably secures the device to the outside of the patient's torso and chest, ensuring it does not shift or loosen during use, thus providing reliable fixation and support for patients with chest trauma.

[0046] Understandably, in existing technologies, immobilization devices are typically required for patients after open-chest surgery, or those in ambulances or emergency rooms, to reduce the possibility of secondary injuries during movement. However, existing immobilization devices are often made of flexible or rigid materials, making it difficult to adjust them to meet different patient support needs. This can lead to displacement, affecting the immobilization and protection effect and resulting in a poor user experience. In this embodiment, the installation and immobilization mechanism improves the stability of the device when worn. Furthermore, the inflatable airbag assembly and support assembly further enhance the flexibility of the immobilization device, allowing for adjustments to the support effect of the device on the torso and chest when worn. This further improves stability and comfort during use, significantly reducing the possibility of secondary injuries to the user.

[0047] Further, see the appendix to the instruction manual. Figure 1 The main body of the device consists of a back-wearing component 1 and a chest-wrapping component 2. One end of the chest-wrapping component 2 is connected and fixed to one end of the back-wearing component 1, while the end of the chest-wrapping component 2 away from the back-wearing component 1 is adapted to be connected to the other end of the back-wearing component 1, thereby forming a receiving space for wearing the main body of the device on the outside of the torso and chest.

[0048] In one embodiment, see the appendix to the specification. Figure 1 and Figure 2 This embodiment further describes the back-wearing assembly 1 and the chest-wrapping assembly 2. The back-wearing assembly 1 includes a back substrate 11 and sliding sleeves 12, while the chest-wrapping assembly 2 includes a chest substrate 21. Specifically, the back substrate 11 has a corresponding first end 111 and a second end 112. One end of the chest substrate 21 is fixedly connected to the first end 111, while the other end of the chest substrate 21 is detachably connected to the second end 112. Thus, after the back substrate 11 and the chest substrate 21 are connected, the device is fixedly worn on the outer side of the torso and chest. The two sliding sleeves 12 are respectively disposed on the first end 111 and the second end 112.

[0049] It should be noted that both the back substrate 11 and the chest substrate 21 are made of materials that are not visible under X-rays. Of course, in actual production applications, other materials can also be used, which will not be described in detail here, and all are within the protection scope of this utility model.

[0050] Furthermore, the mounting and fixing mechanism includes a chest strap fixing assembly 6 and a shoulder strap fixing assembly 5. The shoulder strap fixing assembly 5 includes two shoulder straps 51. One end of each shoulder strap 51 is connected and fixed to the top of the back base plate 11, while the other end of the shoulder strap 51 is adapted to connect to the top of the chest base plate 21 of the chest-wrap wearing assembly 2. This allows the shoulder straps 51 to fix the main body of the device to the outside of the torso chest along the user's shoulder blades, preventing the device from shifting as a whole and losing its effective fixing function.

[0051] Preferably, to further improve the comfort and fit of the fixation device when worn, a second airbag 52 is provided on each shoulder strap 51, and each second airbag 52 is provided with a second inflation valve 53. An air pump inflates the second airbag 52 through the second inflation valve 53 to adjust the tightness of the shoulder strap 51. Furthermore, when the end of the shoulder strap 51 away from the back base 11 is connected to the chest base 21, the second airbag 52 is positioned corresponding to the scapula to restrict scapular movement and provide pressure fixation to the upper chest.

[0052] Furthermore, the other end of the back substrate 11 and the end of the chest substrate 21 furthest from the back substrate 11 are connected by Velcro 7. The back substrate 11 has a portion of the Velcro 7 with a stiffer hook, while the chest substrate 21 has a portion of the Velcro 7 with soft fibers. The stiffer hook portion engages with the soft fiber portion, allowing the back substrate 11 and the chest substrate 21 to be detachably connected. Correspondingly, the shoulder strap 51 has a portion of the Velcro 7 with a stiffer hook, while the chest substrate 21 has a portion of the Velcro 7 with soft fibers.

[0053] The end of the shoulder strap 51 furthest from the back base 11 can also be configured as a hook, and a hanging loop that cooperates with the hook is provided on the chest base 21. The connection between the shoulder strap 51 and the chest base 21 is achieved by the hook and the hanging loop engaging. Of course, in actual production applications, there are various ways to connect the back base 11 and the chest base 21, and the shoulder strap 51 and the chest base 21, which will not be described in detail here, but are all within the protection scope of this utility model.

[0054] In one embodiment, the inflatable airbag assembly is further described. The inflatable airbag assembly includes a plurality of uniformly arranged first airbags 31, each first airbag 31 being provided with a first inflation valve 32, which is adapted to inflate the first airbag 31 by means of an air pump.

[0055] Specifically, three first airbags 31 are respectively provided on the back substrate 11 and the chest substrate 21, so that they fully contact the user's anterior and lateral chest walls to achieve limiting and local pressure fixation of the anterior and lateral chest walls. Preferably, the width of the first airbag 31 located on the chest substrate 21 is greater than the width of the first airbag 31 on the back substrate 11.

[0056] Furthermore, the support assembly includes several elastic support strips 4. Both the back substrate 11 and the chest substrate 21 have openings that match the elastic support strips 4, and openings communicating with these openings are provided on both the back substrate 11 and the chest substrate 21, allowing the elastic support strips 4 to be detachably inserted into the openings along the extension direction of the patient's torso and chest. Generally, the back substrate 11 has two elastic support strips 4, which are respectively and correspondingly positioned on the back substrate, while the chest substrate 21 has six elastic support strips 4.

[0057] Understandably, the elastic support strip 4 possesses a certain degree of elasticity, providing elastic support and achieving axial fixation of the anterior and lateral chest walls. In practical applications, medical staff can selectively insert the elastic support strip 4 into the opening slot according to the needs of the patient's chest wound site, adjusting the main body of the device in that area from flexible to rigid. For example, when the patient's anterior chest requires support, the elastic support strip 4 is inserted into the opening slot of the chest substrate 21; correspondingly, the elastic support strip 4 is inserted into the opening slot of the back substrate to provide support for the back, offering greater selectivity and flexibility.

[0058] In one embodiment, see the appendix to the specification. Figures 1 to 3 This embodiment further describes the chest strap fixing assembly 6 of the mounting and fixing mechanism. The chest strap fixing assembly 6 includes a locking member, a first chest strap group 61 and a second chest strap group 62, which are respectively connected to two sliding sleeves 12.

[0059] Accordingly, the ends of the first chest strap assembly 61 and the second chest strap assembly 62 furthest from the sliding sleeve 12 are adapted to be connected by a locking member. The first chest strap assembly 61 is disposed on the outer side of the chest base 21. When the end of the chest base 21 furthest from the back base 11 is fixed to the other end of the back base 11 by Velcro 7, the first chest strap assembly 61 and the second chest strap assembly 62 can surround the outer side of the chest base 21 and be connected by the locking member to strengthen the fixation of the chest wall. In addition, for patients with arm injuries, the patient's arm can be placed close to the outer side of the device body, and the arm can be limited by the chest strap fixing assembly 6, thereby restricting its movement and protecting the arm.

[0060] It should be noted that both the first chest strap group 61 and the second chest strap group 62 consist of several chest straps 63. Preferably, one end of each chest strap 63 is movably fitted onto the outside of the sliding sleeve 12, allowing the user to adjust the specific position of the chest strap 63 according to actual needs. Generally, both the chest strap 63 and the shoulder strap 51 can be configured as strip-like mesh structures, possessing a certain degree of elasticity and extensibility, to adapt to the body shapes of wounded patients with different chest sizes.

[0061] Additionally, see the instruction manual appendix. Figure 1 Three chest straps 63 are respectively provided on both sides of the back base plate 11. The locking components include hooks 65 and hexagonal buckles 64. The buckles 64 are located at one end of one chest strap 63 of the first chest strap group 61. Correspondingly, the hooks 65 are located at the ends of the other chest straps 63 away from the sliding sleeve 12. The buckles 64 are provided with snap-fit ​​holes corresponding to the hooks 65. Each snap-fit ​​hole is provided with a rocker plate. The hooks 65 are adapted to nest and engage with the rocker plates in the buckles 64 through the snap-fit ​​holes. A pressing groove is provided in the middle of the buckles 64. A button 66 is movably disposed in the pressing groove. A return spring is fixedly disposed below the button 66. One end of the rocker plate is disposed below the button 66. The return spring supports the button 66.

[0062] Understandably, please refer to the instruction manual for guidance during use. Figure 3 The hook 65 is inserted into the buckle 64 through the corresponding locking hole, causing the corresponding rocker to rotate. This moves the hook 65 below the rocker and engages with it under the action of the return spring, thus connecting the chest strap 63 to the buckle 64. To release the connection, simply press the button 66 to rotate the rocker, releasing the hook 65 from its limiting engagement.

[0063] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
