Description

A protective stretcher for emergency treatment of multiple fractures Technical Field

[0001] This application relates to the field of medical device technology, and in particular to an emergency protective stretcher for multiple fractures. Background Technology

[0002] The emergency protective stretcher for multiple fractures is a medical transport device designed specifically for patients with multiple fractures. It has special fixation and protection functions, enabling safe transport without moving the patient and effectively preventing secondary injuries. It is a key medical device for pre-hospital emergency care and in-hospital transport. The main type of stretcher currently in use is the scoop stretcher, which consists of two aluminum alloy or carbon fiber plates on the left and right sides with a clutch device in the middle, which can be separated into two parts and scooped under the body without moving the patient.

[0003] Existing scoop stretchers often employ a fixed-width design in their core structure. The spacing between the two separate stretcher plates is predetermined at the factory, lacking an adjustable fit mechanism. This limits their suitability to patients with standard body types and moderate torso widths. When handling patients with wider torsos, stable and safe transport becomes difficult. Furthermore, the fixed-width load-bearing capacity of these scoop stretchers means that, with obese patients, patients with robust torsos, or patients with wide pelvises and broad shoulders, the load-bearing plates on both sides cannot fully cover the critical stress points of the patient's torso. The patient's shoulders and hips may extend beyond the stretcher's edge, and the back and waist may not fully conform to the stretcher plates, leaving parts of the body suspended and unable to form a uniform support base. This fundamentally undermines the effectiveness of the scoop stretcher design. The inherent stability and load-bearing capacity of scoop stretchers are insufficient to meet the transport adaptation needs of wide-bodied patients. These fixed-width scoop stretchers are mostly used in emergency scenarios requiring strict prevention of secondary injury, such as multiple fractures, spinal injuries, and pelvic injuries. However, wide-bodied patients often have weak body weight-bearing capacity and low tolerance for injuries. Instability and body displacement caused by insufficient stretcher width can directly lead to the shaking and misalignment of fracture ends, easily injuring surrounding muscles, blood vessels, nerves, and internal organs. For patients with spinal injuries, body sliding can cause uneven stress on the spine, leading to cervical and lumbar vertebrae misalignment, increasing the risk of spinal cord injury, exacerbating pain, inducing agitation, and further increasing the emergency risks during transport. This contradicts the core design purpose of scoop stretchers—fixation, protection, and prevention of secondary injury—in emergency care.

[0004] Therefore, it is necessary to propose a protective stretcher for emergency treatment of multiple fractures to solve the above problems. Summary of the Invention

[0005] This application provides an emergency protective stretcher for multiple fractures. In order to improve the technical problem that the spacing of the stretcher boards in the related technology is fixed and fixed, and no width adjustment and adaptation mechanism is set, it is difficult to achieve stable and safe transfer when facing patients with wide torso width, resulting in secondary injury to the patient.

[0006] This application provides an emergency protective stretcher for multiple fractures, including a left stretcher component and a right stretcher component. The left stretcher component and the right stretcher component are two independent parts with completely symmetrical structures. The two stretcher boards are spliced ​​together into a whole by a split buckle. The left stretcher component includes a main support and a torso stretcher board. The torso stretcher board can cover the patient's buttocks and shoulders.

[0007] The torso stretcher board is mounted on the main support. An extension block is also provided on the end of the torso stretcher board away from the right side stretcher board. An adjustment block is provided on the extension block through a first limiting component, which can be telescopically set to accommodate patients of different widths.

[0008] The technical solutions described above in this application embodiment have at least the following technical effects: This stretcher adopts a symmetrical split structure, which can be quickly assembled by disassembly buckles. It can prevent secondary injuries from multiple fractures by transporting the patient without moving or shoveling in. The torso stretcher board supported by the main support accurately covers the core area of ​​the patient's hips and shoulders, avoiding the body from being suspended in the air and ensuring stable support. The extension block, together with the first limiting component, drives the adjustment block to extend and retract, so that the width can be adjusted to adapt to patients of different body types. It has strong versatility and has the advantages of safe transport, convenient operation, and wide adaptability, which greatly improves the quality of emergency transport for multiple fractures.

[0009] In this embodiment, the left stretcher board also includes an extension bracket and a foot stretcher board. The extension bracket is telescopically mounted on the torso stretcher board via a second limiting component, and the foot stretcher board is mounted on the extension bracket to accommodate patients of different heights.

[0010] This technical solution features an extendable support and a foot stretcher board on the left side of the stretcher. The extendable support is telescopically connected to the torso stretcher board via a second limiting component. The foot stretcher board is adapted to the extendable support to achieve adjustable length, accommodating patients of different heights and preventing the feet from being suspended in the air or the torso from being squeezed. The limiting component locks reliably, and the adjustment does not damage the core support. It is easy to operate, prevents secondary injuries caused by transport displacement, and improves the stretcher's adaptability and transport safety.

[0011] In this embodiment, the first limiting component includes a threaded post disposed on the extension block. The adjusting block has an adjusting hole, and the threaded post can pass through the adjusting hole. The distance between the adjusting block and the torso stretcher plate can be adjusted through the adjusting hole and the threaded post. A locking block is threadedly locked on the threaded post to restrict the movement of the adjusting block.

[0012] This technical solution allows the first limiting component to achieve precise width adjustment using a threaded post and an adjustment hole, while the threaded locking block locks and limits the width. The adjustment is flexible and the locking is firm, adapting to patients of different widths, preventing displacement during transport, and is easy to operate without additional tools. It ensures stable and reliable width adaptation, eliminates secondary damage, and improves the safety and accuracy of stretcher use.

[0013] In this embodiment, the second limiting component includes a clamping ring disposed on the torso stretcher plate. The clamping ring has threads on its surface and grooves arranged in an annular array on its surface. A clamping block is disposed on the clamping ring by the threads, so that the clamping ring can abut against the elongation bracket and lock it.

[0014] Through this technical solution, the second limiting component uses a grooved threaded clamping ring and clamping block to achieve locking. The elastic contraction fits tightly, and the locking is firm and resistant to bumps. The threaded operation is convenient and requires no additional tools, which is suitable for emergency needs. It prevents the stretching support from shifting, ensures stable length adjustment, eliminates secondary damage, and improves the safety and reliability of the stretcher's length adaptation.

[0015] In this embodiment, the main support is also provided with a head stretcher board for supporting the patient's head. The head stretcher board is also provided with head pillows on both sides of the patient's head through connectors to facilitate fixing the patient's head.

[0016] This technical solution features a head stretcher board on the main support to support the head and protect the cervical spine. The headrests on both sides are fixed to the head by connectors to prevent shaking and displacement during transport, eliminate secondary injuries to the cervical spine, adapt to different head shapes, provide stability and comfort, and are easy to operate, thus improving the safety and adaptability of the stretcher for head protection.

[0017] In this embodiment, the connector is a hook and loop fastener with a textured surface and a hook and loop fastener with a textured surface located at the bottom of the headrest.

[0018] This technical solution uses hook and loop fasteners on both rough and barbed surfaces for quick and easy headrest installation and adjustment. It requires no tools, fits firmly, adapts to different head shapes, prevents headrest displacement, provides stability and comfort, is easy to operate, ensures reliable head fixation, and prevents secondary damage.

[0019] In this embodiment, the torso stretcher board, foot stretcher board, and head stretcher board are all shovel-type structures, which facilitates the transfer of patients.

[0020] This technical solution uses a shovel-type structure for the torso, feet, and head stretcher boards, enabling shovel-in transport without manual handling, preventing secondary injuries, providing a more stable and secure fit, and offering convenient operation suitable for complex emergency scenarios, thus improving transport safety and efficiency.

[0025] Existing scoop stretchers often employ a fixed-width design in their core structure. The spacing between the two separate stretcher plates is predetermined at the factory, lacking an adjustable fit mechanism. This limits their suitability to patients with standard body types and moderate torso widths. When handling patients with wider torsos, stable and safe transport becomes difficult. Furthermore, the fixed-width load-bearing capacity of these scoop stretchers means that, with obese patients, patients with robust torsos, or patients with wide pelvises and broad shoulders, the load-bearing plates on both sides cannot fully cover the critical stress points of the patient's torso. The patient's shoulders and hips may extend beyond the stretcher's edge, and the back and waist may not fully conform to the stretcher plates, leaving parts of the body suspended and unable to form a uniform support base. This fundamentally undermines the effectiveness of the scoop stretcher design. The inherent stability and load-bearing capacity of scoop stretchers are insufficient to meet the transport adaptation needs of wide-bodied patients. These fixed-width scoop stretchers are mostly used in emergency scenarios requiring strict prevention of secondary injury, such as multiple fractures, spinal injuries, and pelvic injuries. However, wide-bodied patients often have weak body weight-bearing capacity and low tolerance for injuries. Instability and body displacement caused by insufficient stretcher width can directly lead to the shaking and misalignment of fracture ends, easily injuring surrounding muscles, blood vessels, nerves, and internal organs. For patients with spinal injuries, body sliding can cause uneven stress on the spine, leading to cervical and lumbar vertebrae misalignment, increasing the risk of spinal cord injury, exacerbating pain, inducing agitation, and further increasing the emergency risks during transport. This contradicts the core design purpose of scoop stretchers—fixation, protection, and prevention of secondary injury—in emergency care.

[0026] Based on this, in order to improve the technical problem in the related technology that the spacing of the stretcher boards is fixed and not equipped with a width adjustment and adaptation mechanism, making it difficult to achieve stable and safe transfer when facing patients with a wide torso, resulting in secondary injury to the patient, the embodiments of this application provide the following solution.

[0027] Please refer to Figures 1 and 2 together. This application embodiment provides an emergency protective stretcher for multiple fractures. The emergency protective stretcher for multiple fractures includes a left stretcher component 1 and a right stretcher component 2. The left stretcher component 1 and the right stretcher component 2 are two independent parts with completely symmetrical structures. The left and right stretcher boards are spliced ​​into a whole by a split buckle 3. The left stretcher component 1 includes a main support 4 and a torso stretcher board 41. The torso stretcher board 41 can cover the patient's buttocks and shoulders.

[0028] The torso stretcher plate 41 is mounted on the main support 4. An extension block 42 is also provided on the end of the torso stretcher plate 41 away from the right side stretcher plate. An adjustment block 43 is provided on the extension block 42 through the first limiting component 44 to accommodate patients of different widths.

[0029] The emergency protective stretcher for multiple fractures provided in this application embodiment has two independent and symmetrical stretcher components 2 on the left and right sides. They are assembled into a whole by disassembly buckles 3, which allows for scooping and transport without moving the patient. This eliminates secondary injuries such as displacement of fracture ends and spinal misalignment during the transport of patients with multiple fractures. The assembly and unlocking are quick and tool-free, improving emergency rescue efficiency. The symmetrical structure ensures that the stretcher is evenly stressed, preventing tilting during transport and preventing the patient from slipping or falling. It is suitable for confined emergency rescue scenarios and complex transport conditions.

[0030] The left stretcher component 1 is equipped with a main support 4 and a torso stretcher plate 41. The main support 4 provides a stable load-bearing foundation to ensure that the stretcher is resistant to deformation and has reliable load-bearing capacity. The torso stretcher plate 41 precisely covers the core stress areas of the patient's buttocks and shoulders, preventing key parts of the body from being suspended in the air and preventing the pelvis, spine and other frequently injured and vulnerable areas from being aggravated by uneven stress. At the same time, it improves the comfort of transport and relieves the patient's pain and agitation.

[0031] An extension block 42 is provided at the distal end of the torso stretcher plate 41. The extension block 42 is telescopically connected to the adjustment block 43 via the first limiting component 44, so that the stretcher width can be adjusted. This specifically solves the defect of the existing stretcher width being fixed and unable to adapt to patients with wide body types. It can adapt to patients with multiple injuries of different body types and improve versatility. The adjustment process does not damage the core support structure of the torso stretcher plate 41, taking into account both adaptability and support safety. The adjustment is precise and controllable and does not require additional tools, so as not to delay the emergency response and adapt to diverse emergency scenarios.

[0032] In this embodiment, the left stretcher plate also includes an extension bracket 45 and a foot stretcher plate 46. The extension bracket 45 is telescopically mounted on the torso stretcher plate 41 via a second limiting component 47, and the foot stretcher plate 46 is mounted on the extension bracket 45 to accommodate patients of different heights.

[0033] With this configuration, the left stretcher board is equipped with an extension bracket 45 and a foot stretcher board 46. The extension bracket 45 can be telescopically attached to the torso stretcher board 41 via a second limiting component 47, while the foot stretcher board 46 is fixed to the extension bracket 45. This allows for flexible adjustment of the stretcher length, making it suitable for patients with multiple fractures of different heights. It solves the problems of foot suspension and torso bending and compression caused by the fixed length of existing stretchers. The second limiting component 47 can precisely lock the extension stroke, ensuring stable support without slippage after length adjustment and preventing the foot stretcher board 46 from loosening or shifting during transport. The adjustment process does not affect the support performance of the torso stretcher board 41 for the hip and shoulder core area, balancing length adaptability and core support safety. The operation is convenient and tool-free, does not delay emergency response, and further improves the stretcher's adaptability and versatility for patients of different body types, preventing fracture end displacement and torso traction injuries caused by unsuitable length.

[0034] In this embodiment, the first limiting component 44 includes a threaded post 441 disposed on the extension block 42, and an adjustment hole 442 is provided on the adjustment block 43. The threaded post 441 can be inserted into the adjustment hole 442. The distance between the adjustment block 43 and the torso stretcher plate 41 can be adjusted through the adjustment hole 442 and the threaded post 441. A locking block 443 is threadedly locked on the threaded post 441 to limit the movement of the adjustment block 43.

[0035] In this configuration, the first limiting component 44 consists of an extension block 42, a threaded post 441, an adjusting block 43, an adjusting hole 442, and a threaded locking block 443. The threaded post 441 passes through the adjusting hole 442 to allow the adjusting block 43 to slide and adjust the distance, precisely adjusting the stretcher width to fit patients of different body types, thus solving the problem of width fit. The threaded locking block 443 is threaded and locked to limit movement, ensuring a stable and shock-resistant fit, preventing the adjusting block 43 from loosening and shifting during transport, which could lead to width mismatch. The threaded adjustment structure has high precision and can finely adjust the width as needed, ensuring that the patient's torso fits snugly against the stretcher without any gaps. The structure is simple and easy to operate, requiring no auxiliary tools, meeting the needs of efficient emergency care. At the same time, it ensures stable support after width adjustment, preventing secondary injuries caused by loosening, and balancing fit and transport safety.

[0036] In this embodiment, the second limiting component 47 includes a clamping ring 471 disposed on the torso stretcher plate 41. The surface of the clamping ring 471 is provided with threads, and grooves 472 are arranged in an annular array on the clamping ring 471. A clamping block 473 is provided on the clamping ring 471 by threads, so that the clamping ring 471 can abut against the extension bracket 45 to lock it.

[0037] In this configuration, the second limiting component 47 consists of a pressing ring 471 (with threads and annular groove 472) on the torso stretcher plate 41 and a threaded pressing block 473. The threaded drive drives the pressing block 473 to compress the pressing ring 471. With the help of the elastic contraction characteristics of the annular groove 472, the pressing ring 471 tightly abuts against the extension bracket 45 to achieve locking. The locking structure is stable and reliable, resists the impact of transport bumps, and avoids the extension bracket 45 slipping and causing length mismatch. The threaded operation does not require auxiliary tools, and the adjustment and locking are convenient and efficient, which is suitable for the time-sensitive needs of emergency rescue. The locking force can be precisely controlled, taking into account both the locking firmness and the protection of the bracket, ensuring the stability of the support after length adjustment, and preventing the patient's body from being pulled and secondary injured due to the loosening of the bracket. This improves the reliability of the stretcher length matching and the safety of transport.

[0038] In this embodiment, a head stretcher board 5 is also provided on the main support 4 to support the patient's head. A head pillow 51 is also provided on the head stretcher board 5 via a connector 52, which is located on both sides of the patient's head to facilitate the fixation of the patient's head.

[0039] This configuration allows the main support 4 to be equipped with a head stretcher board 5, providing stable support for the patient's head and preventing the head from being suspended, which could lead to cervical spine imbalance and provide targeted protection for the frequently injured and vulnerable cervical spine areas. The head stretcher board 5 is connected to two headrests 51 via connectors 52, which can precisely fit the sides of the head to achieve limited fixation, effectively preventing head rotation and displacement during transport and eliminating secondary injuries such as cervical spine misalignment and spinal cord injury caused by head shaking. The connectors 52 are adjustable to accommodate patients with different head shapes, providing a secure fixation without compressing the soft tissues of the head. This design balances adaptability and comfort, and can be operated without additional tools, meeting the high efficiency requirements of emergency care. In conjunction with the trunk and foot support structures, it provides stable support and protection for the entire body of the patient, improving the safety level of transport.

[0040] In this embodiment, the connector 52 is a hook and loop fastener with a rough surface and a hook and loop fastener with a sharp surface disposed at the bottom of the headrest 51.

[0041] With this design, the connector 52 uses a combination of hook and loop fasteners on the surface of the hook and loop fasteners on the bottom of the headrest 51. This allows for quick and easy attachment and fixation of the headrest 51 without the need for tools, making disassembly and adjustment highly efficient and convenient, perfectly suited for emergency situations where every second counts. The hook and loop fasteners adhere tightly and reliably, resisting the impact of transport and preventing the headrest 51 from shifting or falling off. This ensures effective fixation of the head on both sides, preventing secondary injuries such as cervical spine misalignment caused by head movement. The adhesive structure allows for flexible adjustment of the position and fit of the headrest 51, adapting to patients with different head shapes. It provides soft and pressure-free fixation, balancing stability and comfort. Furthermore, the simple structure makes it easy to maintain, further enhancing the adaptability and safety of the head fixation mechanism.

[0042] In this embodiment, the torso stretcher plate 41, the foot stretcher plate 46, and the head stretcher plate 5 are all shovel-type structures, which facilitate the transfer of patients.

[0043] With this design, the torso, feet, and head stretcher plates 5 all adopt a scoop-like structure, which can be seamlessly scooped in from under the patient's body without lifting the patient throughout the process. This fundamentally avoids secondary injuries caused by moving patients with multiple fractures or cervical spine injuries. The scoop-like structure fits snugly against the patient's torso, head, and feet, providing continuous support for the whole body and preventing stress imbalance caused by local suspension. Combined with the adjustable width and length structure, it can accommodate patients of different body types. The scooping operation is convenient and efficient, requiring no additional tools, and is suitable for complex emergency scenarios such as accident scenes and confined spaces. It shortens the preparation time for transport and improves the safety and efficiency of pre-hospital emergency transport.

[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
