Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to a multi-functional transport vehicle for critically ill patients. Background Technology

[0002] In the field of medical equipment, the transport of critically ill patients is a crucial link, especially in scenarios such as emergency care, operating room transfers, and ward relocation. While traditional transport vehicles can meet basic transportation needs, they still have many shortcomings in practical use. Existing transport vehicles are often single-function and difficult to adapt to complex and changing medical environments. For example, they lack effective support and fixation for the patient's position during transport, which can easily lead to secondary injuries due to bumps or displacement. In addition, existing transport vehicles are cumbersome to operate when docking with hospital beds or other medical equipment, and the connection is not secure enough, which may lead to safety hazards for patients during transport. At the same time, existing equipment often fails to fully consider the ease of operation for medical staff, such as the lack of convenient power interfaces and storage space design, which increases the workload of medical staff. More importantly, existing transport vehicles are significantly lacking in flexibility and adaptability when dealing with special medical needs, such as the need to quickly adjust the structure of the transport vehicle to adapt to patients of different body sizes or special treatment equipment. These problems not only affect the safety and comfort of critically ill patient transport but also limit the improvement of medical efficiency. Therefore, developing a multifunctional transport vehicle that can solve the above problems has important clinical significance and application value. Utility Model Content

[0003] This invention addresses the problems of limited functionality, inconvenient operation, and insufficient connection stability in existing critical care patient transport equipment. It proposes a multi-functional transport vehicle for critically ill patients that is structurally sound, versatile in function, and safe and reliable. To this end, this invention adopts the following technical solution.

[0004] This utility model provides a multi-functional transport vehicle for critically ill patients, including a frame, a top plate, a bottom plate, casters, a power strip, a docking block, a connecting rod, a bed board, and a locking mechanism. The frame serves as the core support of the overall structure, with the top plate fixed to its top and the bottom plate fixed to its bottom. Three [unclear - possibly referring to a specific type of support structure] are installed at the bottom of the bottom plate.

[0005] The omnidirectional wheels are arranged in a triangular pattern. The design of these wheels, with three-point support, achieves both flexibility and stability during movement of the transport vehicle, while avoiding the risk of tipping over due to a shift in the center of gravity. Furthermore, a support rod is welded to the top plate, and the support rod has an integrated hook for hanging infusion bags or other medical equipment. In addition, a power strip is also provided on the top plate to provide stable power support for the medical equipment.

[0006] Furthermore, a docking block is fixed to one side of the bracket, and the docking block has a docking hole for quick installation and disassembly of the connecting rod. One end of the connecting rod has a threaded portion corresponding to the docking hole, and the other end is welded to a connecting plate. A plug and symmetrically arranged magnetic blocks are fixed to one side of the connecting plate, and integrally formed positioning blocks are provided on both sides of the plug. Specifically, a side plate and symmetrically arranged magnetic blocks are fixed to one side of the bed board, and the side plate has slots, positioning grooves, and locking grooves corresponding to the plugs. Through the above design, the connection relationship between the bed board and the connecting plate is clearly defined, providing a basis for the subsequent locking mechanism.

[0007] The locking and unlocking mechanism is one of the core innovations of this invention. The connecting plate and the insert block share a common, interconnected rectangular slot and inner groove. A locking block is slidably connected within the inner groove, and a spring is installed between the locking block and the side wall of the inner groove. When the insert block is inserted into the slot of the side plate, the positioning block and the positioning groove cooperate to achieve initial positioning. Under the action of the spring, the locking block automatically pops out and engages with the slot on the side plate, thus completing the locking. Specifically, a straight rod is welded to the locking block, and a toggle plate is fixed to the top of the rod. Unlocking is achieved by manually moving the toggle plate to retract the locking block into the inner groove. This design not only simplifies the operation process but also ensures the reliability of locking and unlocking.

[0008] Furthermore, the mutual attraction between magnetic block one and magnetic block two enhances the stability between the connecting plate and the bed board. Specifically, magnetic block one and magnetic block two are attracted by magnetic force, preventing loosening caused by external vibration or impact. This magnetic fixing method, combined with the mechanical locking mechanism, forms a double guarantee, significantly improving the safety of the connection between the bed board and the transport vehicle.

[0009] Specifically, this utility model also includes additional functional designs to meet practical usage needs. A placement frame is provided below the base plate for storing emergency medicines or other medical supplies. The design of the placement frame achieves classified storage of items through a reasonable spatial layout, facilitating quick access by medical personnel. Furthermore, the dimensions and structure of the support, top plate, base plate, and other components have been optimized to ensure a compact overall structure of the transport vehicle. And it has all the necessary functions.

[0010] The technical advantages of this utility model are mainly reflected in the following aspects: By integrating functional components such as power strips, hooks, and placement frames, the transport cart can meet various needs during the transport of critically ill patients; the design of connecting rods, docking blocks, insertion blocks, and locking blocks enables quick assembly and disassembly of the bed board and the transport cart, improving efficiency; the combination of magnetic blocks and locking mechanisms ensures a firm connection between the bed board and the transport cart, avoiding safety hazards caused by accidental detachment; the combination design of locking blocks and springs makes locking and unlocking operations simple and reliable, suitable for quick operation by medical staff; and the design of universal wheels allows the transport cart to move flexibly and adapt to the needs of use in different environments.

[0011] In summary, the multi-functional transport vehicle for critically ill patients provided by this utility model has the characteristics of reasonable structure, diverse functions, convenient operation and safety and reliability. It is suitable for the transport of critically ill patients and has broad application prospects. Attached Figure Description

[0014] This utility model provides a multi-functional transport vehicle for critically ill patients, the specific implementation of which is described in conjunction with the appendix. Figure 1 To be continued Figure 4 Please provide a detailed explanation. For example... Figure 1As shown, the overall structure of the transport vehicle consists of a support frame 1 as the core supporting component. A top plate 4 is fixed to the top of the support frame 1, and a bottom plate 2 is fixed to the bottom of the support frame 1. Three triangularly distributed casters 3 are installed at the bottom of the bottom plate 2. This three-point support design achieves both flexibility and stability during movement, while avoiding the risk of tipping over due to a shift in the center of gravity.

[0015] Further integration Figure 2 and Figure 3 A connecting block 6 is fixed to one side of the bracket 1. The connecting block 6 has a connecting hole 61 for quick installation and removal of the connecting rod 7. One end of the connecting rod 7 has a threaded part corresponding to the connecting hole 61, and the other end is welded to a connecting plate 11. A plug 17 and symmetrically arranged magnetic blocks 13 are fixed to one side of the connecting plate 11. The plug 17 has integrally formed positioning blocks 19 on both sides. A side plate 21 and symmetrically arranged magnetic blocks 20 are fixed to one side of the bed board 12. The side plate 21 has a slot corresponding to the plug 17. The inner wall of the slot has positioning grooves 22 that match the positioning blocks 19 on both sides. The side plate 21 also has symmetrically arranged slots 23. The above design clarifies the connection relationship between the bed board 12 and the connecting plate 11 and provides a basis for the subsequent locking mechanism.

[0016] A placement frame 8 is provided below the base plate 2, and a mobile power supply is placed on the placement frame 8. The placement frame 8 is fixedly connected to the base plate 2 by bolts. The placement frame 8 has a partition inside for classifying and storing items. The inner wall of the docking hole 61 of the docking block 6 is provided with internal threads. The threaded part of the connecting rod 7 matches the internal thread of the docking hole 61. Magnetic block 13 and magnetic block 20 are both permanent magnets, and their magnetic field directions are set opposite to each other to achieve mutual attraction.

[0017] like Figure 4 As shown, the connecting plate 11 and the insert block 17 share a common, interconnected rectangular slot 16 and inner groove 25. A locking block 18 is slidably connected within the inner groove 25, and a spring 26 is provided between the locking block 18 and the side wall of the inner groove 25. When the insert block 17 is inserted into the slot of the side plate 21, the positioning block 19 cooperates with the positioning groove 22 to achieve initial positioning. Under the action of the spring 26, the locking block 18 automatically pops out and locks into the locking groove 23 on the side plate 21, thus completing the locking. In particular, a straight rod 24 is welded onto the locking block 18, and a toggle plate 15 is fixed to the top of the straight rod 24. Unlocking is achieved by manually moving the toggle plate 15 to retract the locking block 18 into the inner groove 25. This design simplifies the operation process and ensures the reliability of locking and unlocking.

[0018] The mutual attraction between magnetic block 13 and magnetic block 20 enhances the stability between the connecting plate 11 and the bed board 12. Magnetic block 13 and magnetic block 20 are attracted by magnetic force, preventing loosening caused by external vibration or impact. This magnetic fixing method, combined with a mechanical locking mechanism, forms... This dual protection significantly enhances the safety of the connection between the bed board 12 and the transport vehicle.

In addition, the dimensions and structure of the bracket 1, top plate 4, base plate 2, and other components have been optimized to ensure that the overall structure of the transport vehicle is compact and fully functional.

[0020] The specific operating principle of this utility model is as follows: In actual use, firstly, the threaded part of the connecting rod 7 is screwed into the mating hole 61 of the mating block 6 to complete the quick installation of the connecting rod 7. Then, the bed board 12 is inserted into the slot of the side plate 21 through the insert block 17. The positioning block 19 and the positioning groove 22 cooperate to achieve initial positioning. At this time, the locking block 18 automatically pops out under the action of the spring 26 and locks into the locking groove 23, completing the locking of the bed board 12 and the connecting plate 11. During this process, the magnetic block 13 and the magnetic block 20 are attracted by the magnetic field, further enhancing the stability of the connection. When unlocking is required, medical staff only need to manually move the actuating plate 15 to retract the locking block 18 into the inner groove 25, easily separating the bed board 12 and the connecting plate 11. This design not only simplifies the operation process but also ensures the reliability of locking and unlocking.
