Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary device technology, and specifically relates to a flatbed cart with a shielding function. Background Technology

[0002] In the medical field, stretchers are widely used as an important tool for transporting patients. In practice, patients often need to be transferred between different indoor and outdoor environments.

[0003] Currently, traditional stretchers have a relatively simple structure, mainly consisting of a bed board, legs, and casters. When used indoors, this type of stretcher can generally meet the needs of moving patients from one location to another. However, when it comes to outdoor transport, the limitations of traditional stretchers become apparent. In outdoor environments, weather conditions are complex and changeable. Direct sunlight can cause discomfort to the patient's eyes and skin, and may even affect their condition. In rainy weather, rainwater can easily soak the patient's body, leading to complications such as colds, causing additional suffering and increasing the risk of infection.

[0004] To address the aforementioned issues, some existing technologies attempt to add a shielding structure to the medical flatbed. For example, patent application CN202220534202.4, entitled "A Shielding Device Suitable for Medical Flatbeds," describes a shielding device suitable for medical flatbeds, relating to the field of medical auxiliary device technology. It is used for installation on the upper part of a medical flatbed and includes a cover, a fixing plate, and an elastic band. The lower end of the cover is adapted to the size of the medical flatbed. The cover has an elastic frame that supports it, and the two sides of the cover fit snugly against the two sides of the medical flatbed. The fixing plate is located at both ends of the cover, and the lower end of the elastic frame is connected to the fixing plate, which fixes the cover and the elastic frame to the medical flatbed. The elastic band is connected to the elastic frame located at both ends of the cover, and the lower end of the elastic band is connected to the flatbed.

[0005] This existing technology addresses the difficulty of transferring patients under adverse weather or environmental conditions, which can easily affect their condition. It proposes a shielding device for use on medical stretchers that can be quickly and stably installed and removed to block the influence of adverse external environments and ensure the safety and comfort of patients during transfer. However, in actual use, the shield needs to be removed as a whole, which is cumbersome. Patent literature states that the shield can be placed at the bottom of the medical stretcher after removal, but not all medical stretchers have space at the bottom for placing the shield. If there is no space at the bottom of the medical stretcher, medical staff can only store the shield separately and install it when needed. Therefore, this shielding device is cumbersome to use because it needs to be disassembled and reassembled as a whole with the medical stretcher, and it is very inconvenient to store separately when there is no space at the bottom of the stretcher. Utility Model Content

[0006] The present invention aims to provide a flatbed cart with a shielding function, which is mainly used to solve the technical problems of existing shielding devices, such as the need for overall disassembly and assembly of medical flatbed carts, the inconvenience of disassembly and assembly, and the great inconvenience of separate storage when facing flatbed carts with no place to put the bottom.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A flatbed cart with a shielding function includes a bed board with several bed legs installed at the bottom. Universal wheels are installed at the lower ends of the bed legs. A first fixing block and a second fixing block are fixed to both sides of the bed board. Each of the first and second fixing blocks has a mounting groove. A deformable support component is installed in the mounting groove. The first fixing block also has a receiving groove, in which a baffle is placed. The end of the baffle away from the first fixing block is detachably connected to the second fixing block. The support component is positioned below the baffle to support it. A limiting component for restricting the deformation of the support component is installed on the outer wall of the mounting groove.

[0009] In this solution, when a patient needs to be transferred outdoors, the deformation of the support component is limited by the limiting component to form a support. The tarpaulin is then detachably fixed to the second fixing block, passing over the top of the bed board. The tarpaulin, mounted on the deformable frame, forms a shield to prevent the patient from being exposed to sun and rain during outdoor transfers. The bed board is then pushed to transfer the patient. Once the patient is transferred indoors, the tarpaulin is removed from the second fixing block, rolled up, and stored in the receiving slot. The support component is then deformed and stored in the mounting slot, allowing the patient to be transferred from the bed board. Compared to existing technologies, in this solution, both the support component and the tarpaulin are connected to the bed board of the trolley. They do not require separate storage after disassembly. During installation, the support component is simply supported, and the tarpaulin is passed over the support component and connected to the second fixing block. This makes disassembly and storage convenient. In summary, this solution solves the technical problems of existing shielding devices, which require the entire medical trolley to be disassembled and assembled, which is cumbersome. Furthermore, it is inconvenient to store separately when using a trolley with no space at the bottom.

[0010] Preferably, the support assembly includes two support frames that can be deformed and stored in the mounting slot. Each support frame includes four connecting rods hinged end-to-end, with one end of each rod fixedly connected to the inner wall of the mounting slot. In this design, the four connecting rods are hinged end-to-end to form a parallelogram mechanism, and the deformation of three of the connecting rods creates a frame-like support. Alternatively, the deformation can compress the four connecting rods, bringing them closer together and arranging them nearly in a straight line within the mounting slot, facilitating the opening and storage of the support assembly.

[0011] Preferably, the limiting component includes a third fixing block fixed to the outer wall of the receiving groove. A sliding groove is fitted onto the side of the third fixing block near the support frame. A sliding hole is formed at the bottom of the sliding groove. A locking block with its upper and lower surfaces in contact with the inner wall of the sliding groove is slidably connected within the sliding groove. A slider is fixed to one end of the locking block near the sliding groove, passing through the sliding hole and sliding within it. A limiting plate is fixed to the end of the slider at the outer surface of the third fixing block to prevent the slider from retracting into the sliding groove. A spring is fixed to the side wall of the sliding groove, with the end of the spring away from the sliding groove fixed to the surface of the locking block. The end of the locking block away from the third fixing block is bent to form a hook, which can hook a connecting rod, keeping the contacting connecting rod in a vertical state. In this solution, pulling the limiting plate allows the locking block to move against the spring. Then, the connecting rod is rotated into the hook of the locking block. Releasing the force pulling the limiting plate causes the locking block to hook the connecting rod under the push of the spring, keeping the connecting rod in a vertical state. In this design, one limiting component can limit one support frame. Therefore, this device has four limiting components, which limit the four support frames respectively.

[0012] Preferably, the side of the third fixing block near the support frame at the bend is machined into a wedge-shaped surface. The connecting rod contacts and presses against the wedge-shaped surface, causing the locking block to slide in the direction of spring compression. In this solution, when the support frame is transformed into a frame-type support structure, one of the four connecting rods rotates and presses against the wedge-shaped surface, causing the locking block to move in the direction of spring compression until the connecting rod passes over the wedge-shaped surface and engages with the hook of the locking block. The pressure on the spring is released, pushing the locking block back to its original position to lock the connecting rod, keeping the connecting rod vertical. The connecting rod in contact with the locking block and the connecting rod fixed in the mounting groove have a fixed angle, thus fixing the shape of the support frame, forming a frame-type support to support the baffle. When the support frame needs to be deformed and stored, the limiting plate is moved to disengage the locking block from the connecting rod, and then the connecting rod is rotated to disengage from the locking block.

[0013] Preferably, a plurality of fixing rings are fixed to the upper surface of the second fixing block, and a plurality of hooks corresponding one-to-one with the fixing rings are fixed to one end of the baffle cloth near the second fixing block. The hooks can be hooked into the fixing rings. In this solution, the baffle cloth and the second fixing block can be detachably connected by hooking the hooks into the fixing rings.

[0014] Preferably, a baffle is detachably connected to the edge of the cover near the patient's head, and the end of the baffle away from the cover can contact the bed board. In this design, if outdoor rain or sunlight easily shines into the area under the cover from both ends of the bed board, causing discomfort to the patient, the cover can be installed on the baffle to further protect the patient's head.

[0015] Preferably, the bed board is equipped with guardrails on both sides. The guardrails are used to protect the patient from the sides. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will now be described based on its overall structure.

[0030] like Figure 1 As shown, the flatbed cart with shielding function in this embodiment is mainly composed of a bed board 1, bed legs, casters, a first fixing block 21, a second fixing block 22, a support assembly, a baffle 4, and a limiting assembly.

[0031] The bed board 1 serves as the main body for supporting the patient, and several bed legs are installed at its bottom. Universal wheels are installed at the lower ends of the bed legs to allow the flatbed to move flexibly.

[0032] A first fixing block 21 and a second fixing block 22 are fixed to both sides of the bed board 1, providing a foundation for the installation of the support assembly and the cover 4. Both the first fixing block 21 and the second fixing block 22 have mounting grooves, and the first fixing block 21 has a receiving groove. The receiving groove is used to store the cover 4. When transferring a patient outdoors, the cover 4 is removed from the receiving groove, passed over the top of the bed board 1, and its end away from the first fixing block 21 is detachably connected to the second fixing block 22. Simultaneously, a deformable support assembly is installed in the mounting grooves on the first fixing block 21 and the second fixing block 22. This support assembly is located below the cover 4, providing support for the cover 4 and forming a shielding structure to effectively prevent the patient from being exposed to sun and rain during outdoor transfers. After the patient is transferred indoors, the cover 4 can be removed from the second fixing block 22, rolled up into the receiving groove, and the support assembly can be deformed into the mounting groove for storage, facilitating the transfer of the patient from the bed board 1.

[0033] like Figure 3 As shown, the support assembly includes two support frames 3 that can be deformed and stored in the mounting slot. Each support frame 3 consists of four connecting rods 31 hinged end to end, with one end of the connecting rod 31 fixedly connected to the inner wall of the receiving slot. This structure forms a parallelogram mechanism with good deformation characteristics. When the baffle 4 needs support, the support frame 3 is manipulated to deform three of the connecting rods 31, forming a frame-type support structure that provides stable support for the baffle 4. When stored, further deformation can bring the four connecting rods 31 closer together, aligning them almost in a straight line, allowing for easy placement in the mounting slot, thus enabling convenient opening and storage of the support assembly.

[0034] like Figure 3 , 4 As shown in Figures 5 and 6, the limiting components are used to restrict the deformation of the support components, ensuring that the support components maintain a stable supporting state during use. Each limiting component can limit one support frame 3. This device is equipped with four limiting components, which limit the four support frames 3 respectively. The limiting components include a third fixing block 23 fixed to the outer wall of the receiving groove. The third fixing block 23 has a sliding groove on the side near the support frame 3, and a sliding hole 26 is formed at the bottom of the sliding groove.

[0035] A locking block 24 is slidably connected within the slide groove. The upper and lower surfaces of the locking block 24 contact the inner wall of the slide groove, ensuring stable sliding within the groove. A slider 241, passing through a sliding hole 26 and capable of sliding within the sliding hole 26, is fixed to the end of the locking block 24 near the slide groove. A limit plate 242 is fixedly connected to the end of the slider 241 at the outer surface of the third fixing block 23 to prevent the slider 241 from retracting into the slide groove. A spring 25 is fixed to the side wall of the slide groove, with the end of the spring 25 away from the slide groove fixed to the surface of the locking block 24. The end of the locking block 24 away from the third fixing block 23 is bent to form a hook, which can hook onto the connecting rod 31, keeping the contacting connecting rod 31 in a vertical position.

[0036] In actual operation, pulling the limiting plate 242 allows the locking block 24 to move against the elastic force of the spring 25. Then, the connecting rod 31 is rotated into the hook of the locking block 24. After releasing the force of pulling the limiting plate 242, the locking block 24 hooks the connecting rod 31 under the push of the spring 25, keeping the connecting rod 31 in a vertical state. Due to

[0037] Furthermore, the side of the third fixing block 23 near the support frame 3 at the bend is machined into a wedge shape. When the support frame 3 is transformed into a frame-type support structure, one of the four connecting rods 31 rotates and presses against the wedge-shaped surface, causing the locking block 24 to move towards the compression spring 25 until the connecting rod 31 crosses the wedge-shaped surface and engages with the hook of the locking block 24. At this point, the pressure on the spring 25 is released, and the locking block 24 is pushed back to its original position to lock the connecting rod 31, keeping the connecting rod 31 in a vertical state. This fixes the shape of the support frame 3, forming a stable frame-type support to support the baffle 4. When it is necessary to deform and retract the support frame 3, the limiting plate 242 is moved to disengage the locking block 24 from the connecting rod 31, and then the connecting rod 31 is rotated to disengage from the locking block 24.

[0038] To facilitate easier assembly and disassembly of the baffle 4 and the second fixing block 22, several fixing rings 221 are fixed to the upper surface of the second fixing block 22, and several hooks 41 corresponding to the fixing rings 221 are fixed to one end of the baffle 4 near the second fixing block 22. By hooking the hooks 41 into the fixing rings 221, the baffle 4 and the second fixing block 22 are detachably connected. This connection method is simple and convenient, allowing for quick installation and disassembly of the baffle 4 when needed.

[0039] A flap 5 is attached to the edge of the cover 4 near the patient's head via Velcro. The end of the flap 5 away from the cover 4 can contact the bed board 1. In outdoor environments, if rain or sunlight easily shines from both ends of the bed board 1 under the cover 4, causing discomfort to the patient, the flap 5 can be installed to further protect the patient's head and improve the comprehensiveness of the shielding function. When the outdoor environment is relatively harsh, the flap 5 can also be installed at the end of the cover 4 near the patient's feet as needed to provide comprehensive protection for the patient. If the outdoor environment is relatively comfortable, the flap 5 can be left uninstalled at the end near the feet to maintain the breathability of the space formed by the flap 5 and the bed board 1.

[0040] To protect the patient from the sides, guardrails are installed on both sides of the bed board 1. The guardrails can prevent the patient from slipping off the side during the movement of the stretcher, increasing the patient's safety when using the stretcher.

[0041] As can be seen from the above, the technical principle of this utility model is as follows:

[0042] In use, rotating the support frame 3 causes the link 31 closest to the locking block 24 to press against the wedge-shaped surface of the locking block 24 and enter the hook of the locking block 24. Under the push of the spring 25, the hook and the end wall of the mounting groove together limit the link 31, keeping the link 31 upright, thus forming a frame-shaped support structure (e.g., Figure 3 (As shown), then pull the end of the cover 4 to the second fixing block 22, so that the hook 41 hooks the fixing ring 221, and the cover 4 passes over the top of the support frame 3 and is mounted on the support frame 3, to cover and protect the patient on the bed board 1 of the flatbed; when it is necessary to remove the cover 4, first disengage the hook 41 from the fixing ring 221, roll the cover 4 into the receiving groove, and then move the limiting plate 242 to drive the locking block 24 out of the surface of the connecting rod 31, so that the connecting rod 31 can rotate, thereby causing the support frame 3 to deform into a strip and be inserted into the installation groove (as shown). Figure 8 (As shown).

These descriptions are not intended to limit the present invention to the precise forms disclosed, and it is obvious that many changes and variations can be made based on the above teachings.
