Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a stretcher that facilitates the transfer of bedridden patients. Background Technology
[0002] In medical settings, transferring patients from beds to stretchers is a common procedure. Currently, with the increasing demand for healthcare services, the requirements for the safety, efficiency, and comfort of the transfer process are constantly rising. However, traditional transfer methods often require significant physical exertion from medical staff, and improper handling during the transfer may cause discomfort or even secondary injury to the patient. Therefore, developing a stretcher that facilitates the transfer of bedridden patients is of great importance, aiming to provide medical staff with a more convenient transfer tool while ensuring the safety and comfort of patients during the transfer process.
[0003] Existing patient transport stretchers have significant drawbacks. Transferring a patient from the bed to the stretcher often requires at least 4-5 people working together, with the method involving multiple people holding the bed sheet and lifting the patient. This method not only consumes a large amount of manpower but can also delay patient transport in emergencies due to untimely manpower allocation. Furthermore, during multi-person collaboration, the varying degrees of force applied by different individuals can easily lead to swaying and jolting of the patient during transport, increasing discomfort and the risk of injury, especially for patients with severe injuries, fractures, or post-operative conditions, potentially causing secondary injuries due to improper handling. Moreover, this method of relying on bed sheets lacks stability and reliability; the sheets are prone to slipping or shifting, further compromising transport safety. In addition, existing stretchers may have design flaws in terms of storage and carrying, such as difficulty in folding and large space requirements, causing considerable inconvenience to medical staff in their daily work. Therefore, we propose a stretcher that facilitates the transport of bedridden patients to address the aforementioned problems. Utility Model Content

[0025] The following is in conjunction with the appendix Figure 1-8 The present invention will be described in further detail below.
[0026] Example 1, refer to Figure 1-8 In this embodiment, the present invention addresses the significant drawbacks of existing patient transport stretchers. Transferring a patient from the bed to the stretcher often requires the combined efforts of at least 4-5 people, with the patient being lifted by holding the bed sheet. This method is not only labor-intensive but can also delay patient transport in emergencies due to insufficient manpower allocation. Furthermore, the inconsistent force exerted by different individuals during the transfer can cause the patient to sway and bounce, increasing discomfort and the risk of injury, especially for patients with severe injuries, fractures, or post-operative conditions, potentially leading to secondary injuries from improper handling. Moreover, this method of lifting with the bed sheet lacks stability and reliability; the sheet is prone to slipping or shifting, further compromising transport safety. Additionally, existing stretchers may have design flaws in terms of storage and carrying, such as difficulty in folding and large space requirements, causing inconvenience to medical staff. Therefore, this invention discloses a stretcher that facilitates the transport of bedridden patients.
[0027] The stretcher includes a left stretcher unit 1 and a right stretcher unit 2, which are mirror-symmetrical. The upper and lower surfaces of the left stretcher unit 1 are provided with several linearly arrayed strip-shaped slots 3. The stretcher also has three devices for secure fixation: a first fastening module 4, a second fastening module 5, and a third fastening module 6. The first fastening module 4 includes a lower clamping member 7 and an upper clamping member 8 pivotally connected above the lower clamping member 7. The first fastening module 4 has several slots 3 embedded within it. The magnetically attracted magnet 9, along with the mirror-symmetrical left stretcher unit 1 and right stretcher unit 2, and the linearly arrayed strip slots 3 on the upper and lower surfaces of the left stretcher unit 1, and equipped with a first fastening module 4, a second fastening module 5 and a third fastening module 6, achieves the goal of efficient and stable transfer of patients in hospital beds. It also allows for flexible selection of fastening modules and strip slots 3 for fixation during the transfer process, greatly improving the stability and comfort of patient transfer and reducing the risk of secondary injury.
[0028] The second fastening module 5 includes a lower gripping component 10, with a magnet 9 fixed at its front end that is magnetically compatible with the lower strip slot 3. The third fastening module 6 includes a lower support component 11, with several guide grooves 12 at its bottom. An upper support component 13 with an arc-shaped profile and a curvature center aligned with the left stretcher unit 1 is slidably installed in the guide grooves 12. By installing the second fastening module 5, which includes a lower gripping component 10 with a magnet 9 magnetically compatible with the strip slot 3 at its front end, and the third fastening module 6, which has guide grooves 12 at its bottom and an upper support component 13 with an arc-shaped profile and a curvature center aligned with the left stretcher unit 1, the purpose of enhancing the stretcher's ability to fix and support patients and related items is achieved. This provides more stable and reliable support and fixation during patient transport, reduces shaking and displacement, and improves transport safety and comfort.
[0029] The left stretcher unit 1 has a "[" shaped frame structure, and the right stretcher unit 2 has a "]" shaped frame structure. The right side of the left stretcher unit 1 is fixed with a first detachable connecting component 14, and the left side of the right stretcher unit 2 is fixed with a second detachable connecting component 15. By installing the left stretcher unit 1 with a "[" shaped frame structure and the right stretcher unit 2 with a "]" shaped frame structure, and the first detachable connecting component 14 and the second detachable connecting component 15 fixed on the right side of the left stretcher unit 1 and the left side of the right stretcher unit 2 respectively, the purpose of facilitating the assembly, disassembly and storage of the stretcher is achieved, thereby improving the flexibility and convenience of stretcher use and facilitating rapid deployment and storage in different scenarios.
[0030] The second detachable connecting component 15 has a wedge-shaped protrusion 16 on its left side, the surface of which is sloped. A first limiting groove 17 is provided on the top of the second detachable connecting component 15. The first detachable connecting component 14 has a limiting groove 18 on its right side that matches the shape of the wedge-shaped protrusion 16. A limiting locking member 19 is pivotally mounted on the top of the first detachable connecting component 14. A first limiting protrusion 20 on the right side of the limiting locking member 19 engages with the first limiting groove 17. The first detachable connecting component 14 is equipped with a limiting protrusion 18 on its left side. The second detachable connecting component 15 (with a sloping surface) and a first limiting slot 17 at the top, and the first detachable connecting component 14 (with a limiting groove 18 that fits with the wedge-shaped protrusion 16 on the right side and a limiting locking piece 19 with a first limiting protrusion 20 mounted on the top via a pivot) achieve the purpose of making the left stretcher unit 1 and the right stretcher unit 2 stably connected and easy to disassemble. It realizes the effect of quick positioning and tight fit when connecting, and simple operation when disassembling, thus improving the efficiency and stability of stretcher assembly and disassembly.
[0031] A first pre-tension spring 21 is elastically connected below the limiting locking member 19. The first pre-tension spring 21 always applies an elastic pre-tension force to the limiting locking member 19, keeping the first limiting protrusion 20 on the limiting locking member 19 locked in the first limiting slot 17. By installing the first pre-tension spring 21 elastically connected below the limiting locking member 19, and by having the spring always apply an elastic pre-tension force to the limiting locking member 19, the purpose of ensuring that the first limiting protrusion 20 on the limiting locking member 19 is stably locked in the first limiting slot 17 is achieved. This enhances the reliability and stability of the connection between the left and right stretcher units 2, avoids loosening of the connection due to accidental vibration or collision during stretcher use, and ensures the safety of patient transport.
[0032] The left stretcher unit 1 and the right stretcher unit 2 are provided with a movable hinge assembly 22 that can be bent 180° in the middle. The movable hinge assembly 22 includes an upper hinge block 23 and a lower hinge block 24. A hinge shaft 25 passes through the middle of the upper hinge block 23. By installing the movable hinge assembly 22, which is composed of an upper hinge block 23 and a lower hinge block 24 and has a hinge shaft 25 passing through the middle of the upper hinge block 23, the left stretcher unit 1 and the right stretcher unit 2 can be bent 180°. This reduces the space occupied by the stretcher when it is stored and makes it easier to carry and store.
[0033] The lower hinge block 24 has an unlocking lever 26 mounted on its top via a pivot. A return spring 27 is elastically connected below the unlocking lever 26. The upper hinge block 23 has a positioning groove 28 on its rear side for cooperating with the unlocking lever 26 to achieve a limit position. In actual use, four fastening modules are required, one each at the front and rear of the hinge assembly of the left stretcher unit 1 and the right stretcher unit 2. By using the unlocking lever 26 mounted on the top of the lower hinge block 24 via a pivot, the return spring 27 elastically connected below it, and the positioning groove 28 on the rear side of the upper hinge block 23, and by equipping the left stretcher unit 1 and the right stretcher unit 2 with a fastening module at the front and rear of the hinge assembly, the bending and locking of the left stretcher unit 1 can be flexibly controlled, and the overall stability of the stretcher can be enhanced. This achieves the effect of being able to conveniently adjust the shape of the stretcher according to actual needs, and ensuring reliable fixation of the stretcher during transport, thus ensuring the safe and stable transport of the patient.
[0034] Operating Method of a Novel Portable Bed-Trolley Patient Transfer Stretcher Based on Symmetrical Structure and Spring-Magnetic Locking: The novel symmetrical portable bed-trolley patient transfer stretcher is simple and efficient to operate, requiring only two people to safely transfer the patient from the bed to the trolley. First, take out two stretcher units that are identical in structure and mirror-symmetrical in their stored state. The operator holds the stretcher unit's hinge block at any position in front of or behind it with both hands and brings the two parts together upwards. During this process, the return spring 27 continuously applies an upward force to the rear of the unlocking lever 26, which is pivotally mounted on the top of the lower hinge block 24, causing a continuous downward force to the front of the unlocking lever 26. When the lower hinge block 24 and the upper hinge block 23 are brought together to a horizontal angle, the slope in front guides the lower hinge block 24 to smoothly engage with the positioning groove 28 on the rear side of the upper hinge block 23, achieving a stable lock on the movable hinge assembly 22. Next, connect the two stretcher units. A first detachable connecting component 14, fixed to the right side of one stretcher unit, is precisely aligned with a second detachable connecting component 15, fixed to the left side of the other stretcher unit. This allows the wedge-shaped protrusion 16, sloping on the left surface of the second detachable connecting component 15, to slide smoothly into the limiting groove 18 on the right side of the first detachable connecting component 14. During this process, the wedge-shaped protrusion 16 pushes the top of the first detachable connecting component 14 upwards via a pivot-mounted limiting lock 19. Once the wedge-shaped protrusion 16 has fully slid into the limiting groove 18, the limiting lock 19 quickly resets under the elastic preload of the first preload spring 21, and its first limiting protrusion 20 precisely engages with the first limiting slot 17 on the top of the second detachable connecting component 15, completing the reliable connection of the two stretcher units. Afterwards, the patient's sheet is tidied and laid flat on the connected stretcher. Based on actual needs and operating habits, one of three devices for secure fixation is selected, with four of each type prepared. If the first fastening module 4 is selected, the lower clamping component 7 is placed under the bed sheet. The upper clamping component 8, which is connected to the lower clamping component 7 via a pivot, cooperates with the internally embedded magnet 9, which magnetically attracts the strip slot 3 on the stretcher unit, achieving a stable fixation. If the second fastening module 5 is used, the magnet 9 fixed at the front end of the lower gripping component 10 is aligned with the strip slot 3 below the stretcher unit for adsorption and fixation. If the third fastening module 6 is used, the lower support component 11 is first placed in a suitable position, and then the position of the upper support component 13 is adjusted by the guide groove 12 at the bottom of the lower support component 11, so that its arc contour fits tightly against the stretcher unit, completing the fixation operation. Finally, two operators each hold the two fixed fastening modules with both hands, and by maintaining smooth and coordinated movements, slowly and evenly lift the stretcher, safely and smoothly transferring the patient to the trolley, completing the entire transfer process.
[0035] The specific working principle is as follows: By installing an integrated stretcher device with structures including strip-shaped slots 3, multiple fastening modules, detachable connecting components, and movable hinge components 22, the manpower required to transfer patients from their beds to trolleys is reduced. This allows for convenient and efficient transfer operations with only two people, significantly saving labor costs and avoiding the risk of patient swaying and secondary injury caused by uneven force application during multi-person operations, greatly improving the safety and convenience of the transfer process. Through the synergistic effect of the above-mentioned structures—including the secure fixing modules for the patient and related items, the detachable connecting components ensuring reliable stretcher assembly, and the movable hinge components 22 allowing for flexible adjustment of the stretcher's shape—the patient transfer process is optimized. It enables precise control of the stretcher's movement and placement even with two operators, reducing transfer time, improving the work efficiency of medical staff, securing more timely treatment for patients, and improving the patient's experience during transfer.
[0036] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
