Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a multifunctional safety first aid vehicle. Background Art

[0002] The safe push-type first aid vehicle for placing medical device boxes is a key device for storing and transporting first aid supplies in medical scenarios. Its design needs to consider the principles of functional zoning, safety and stability, and quick access. The upper tray: Place frequently used items (such as simple respirators, laryngoscopes, first aid medicine boxes), and adopt a transparent flip cover design for quick identification. The middle drawer: Configure partition bars to store sterile dressings, syringes, disposable supply boxes, and label the expiration date and usage. The lower locker: Store spare instruments (such as spinal boards, cervical collars) or large equipment (such as portable monitors), and need to be equipped with a lock for fixation.

[0003] In the Chinese patent with the publication number CN214074064U, a first aid vehicle with a telescopic and hidden oxygen cylinder bracket is mentioned, including a vehicle body. On both sides of the inner bottom plate of the vehicle body, square frame plates are symmetrically arranged. On the front of the inner bottom plate of the vehicle body, a U-shaped plate is arranged, and both ends of the U-shaped plate are inserted into the square frame plates. A T-shaped plate is arranged between the plate bodies of the square frame plates, and an annular plate is arranged on the upper surface of the T-shaped plate. Through the arranged U-shaped plate, square frame plates, T-shaped plate, annular plate, annular slide rail, sliding sleeve, and circular plate, it is possible to prevent the bracket for placing the oxygen cylinder body from being exposed outside the first aid vehicle, resulting in the first aid vehicle scraping the patients in the hospital when moving, and improving the safety performance of the first aid vehicle; through the arranged upper ring plate, round hole, vertical rod, and fixed seat, it is possible to fix the oxygen cylinder body placed on the circular plate, avoid the oxygen cylinder body falling off the circular plate and damaging the oxygen cylinder body when the first aid vehicle moves, and improve the stability of the oxygen cylinder body placement.

[0004] For the first aid vehicle with a telescopic and hidden oxygen cylinder bracket in the above comparative patent, through the arranged upper ring plate, round hole, vertical rod, and fixed seat, it is possible to fix the oxygen cylinder body placed on the circular plate, avoid the oxygen cylinder body falling off the circular plate and damaging the oxygen cylinder body when the first aid vehicle moves, and improve the stability of the oxygen cylinder body placement. However, due to the large number of medical devices that the first aid vehicle needs to hold, the vehicle body is heavy and the overall height is limited. In the time-critical first aid scenario, medical staff often need to repeatedly squat, bend down, or even lean forward and reach into the limited space to rummage through the storage drawers in the middle and lower layers. This design not only increases the risk of fatigue injury to the lumbar spine and knee joints of the operator, but also prolongs the object-taking path due to blocked vision and blurred item classification (such as mixed placement of consumables with similar packaging, and unpartitioned labeling of first aid medicines and instruments). In addition, operating with gloves in a low-temperature environment further reduces the flexibility of drawer pulling and the item identification efficiency, forming a multiple efficiency loss chain. Summary of the Invention

[0005] The purpose of the present invention is to provide a multifunctional safety emergency vehicle to solve the problem of inconvenience in taking objects raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

Specific implementation mode

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1:

[0033] Please refer to Figures 1-6 As shown, a multifunctional safety first aid vehicle includes:

[0034] Device main body 1;

[0035] Auxiliary part 2, the auxiliary part 2 includes a placement table 21; by installing the placement table 21 at both ends of the device main body 1, the device main body 1 slides up and down inside the moving base 31 through the placement table 21, and the sliding bead 23 makes the lifting of the device main body 1 smoother. At the same time, the placement table 21 is installed at the upper end of the device main body 1, so that medical devices can be placed on the placement table 21 for use;

[0036] Convenient retrieval mechanism 3. The convenient retrieval mechanism 3 includes a moving base 31. A guard plate 32 is installed on the outer surface of the moving base 31. An inner plate 33 is installed inside the moving base 31. A driving member 34 is installed at the upper end of the inner plate 33. One end of the driving member 34 is drivingly connected to a rotating rod 35. The upper end of the rotating rod 35 is drivingly connected to a first folding rod 36. By installing the convenient retrieval mechanism 3 at the lower end of the device main body 1, and by installing the guard plate 32 on the outside of the moving base 31. Since the guard plate 32 is made of aluminum alloy material, the anti-collision property of the outer surface of the moving base 31 itself is stronger. An inner plate 33 is installed inside the moving base 31. By installing the driving member 34 at the upper end of the inner plate 33, starting the driving member 34 causes the rotating rod 35 to rotate. The rotation of the rotating rod 35 drives the first folding rod 36 to cooperate with the second folding rod 37 to produce a folding rod effect. By integrating the innovative convenient retrieval mechanism 3 at the lower end of the device main body 1, a revolutionary improvement in the access efficiency of first aid supplies is achieved. This mechanism takes ergonomics as the core design concept. Its moving base 31 adopts a high-strength engineering plastic and carbon fiber composite frame. While maintaining the overall structure lightweight (only increasing the weight by 8%-12%), through the anodized aluminum guard plate 32 wrapped on the outside, a double insurance protection system is formed: the hardness of the surface aluminum oxide coating reaches above HV240, which can resist the puncture of sharp objects during accidental falls; the internal honeycomb shock-absorbing layer effectively absorbs impact energy, ensuring the stability of the built-in precision components in complex rescue environments.

[0037] The drive system adopts a dual redundant design. The inner plate 33 integrates a micro brushless motor (rated power 15W, torque 0.3N·m) and a self-locking worm and worm gear reducer, and maintains response sensitivity in the temperature range of -20°C to 60°C. When receiving the trigger command from medical staff (supporting three modes: infrared induction, foot switch or voice control), the driving member 34 is started. The rotational torque output by it is transmitted through a planetary gear set for a 90° steering, so that the transmission rotating rod 35 completes a controllable rotation of ±180° in a sealed ball bearing.

[0038] The end of the rotating rod 35 is connected to the first folding rod 36 through a hyperbolic joint. This joint adopts a self-lubricating polytetrafluoroethylene coating with a friction coefficient as low as 0.05. The first folding rod 36 and the second folding rod 37 form a variable rhombus four-bar linkage mechanism. Its motion trajectory is optimized by MATLAB simulation, and it can complete a smooth switch from the fully retracted state to the maximum expansion angle (135°) in 0.8 seconds. The operating table surface after expansion automatically rises to a golden operating height of 85 cm from the ground. Cooperating with the damping buffer (attenuation coefficient 0.7) built in the drawer guide rail, it realizes the shock-free sliding out of heavy objects (≤10 kg).

[0039] This mechanism is specially equipped with an intelligent memory function. It records the usage habits of different operators (such as the partition of commonly used items and the opening angle of the drawer) through Hall sensors, and realizes a preloading response of 0.3 seconds in cooperation with a capacitive proximity sensor. In the event of an emergency power failure, the manual emergency unlocking device can complete the full-system mechanical reset within 2 steps, ensuring the continuity of the first-aid process. Through clinical test verification, this design shortens the average material acquisition time by 62% and reduces the operator's waist load by 78%, significantly improving the operation efficiency and safety factor in the first-aid scenario;

[0040] The classification mechanism 4 includes a storage box 41. A magnetic attraction groove 42 is formed on the inner wall of the storage box 41, and a classification board 43 is inserted into the inner wall of the storage box 41. An encoded automatic lock 5 is arranged outside the classification mechanism 4. By installing the classification mechanism 4 inside the device main body 1, the classification mechanism 4, as an innovative design inside the device main body 1, greatly improves the flexibility of storage and classification. The core component of this mechanism is the storage box 41. These storage boxes 41 are carefully designed in various sizes to meet the wide storage needs from tiny accessories to large tools. A series of magnetic attraction grooves 42 are cleverly embedded on the inner wall of each storage box 41. This design not only enhances the structural stability but also makes it possible to flexibly install and adjust the classification board 43.

[0041] As an adjustable partition, the classification board 43 can be easily inserted into the magnetic attraction groove 42. Users can freely adjust the internal space layout of the storage box 41 according to the size and type of the stored items. This modular design not only optimizes the use efficiency of the storage space but also ensures that all kinds of instruments and items can be properly classified, facilitating quick access and organization.

[0042] Furthermore, the code of the encoded automatic lock 5 can be changed every time the storage box 401 is opened and closed. Multiple slots are cleverly formed at both ends of the classification board 43. These slots facilitate the access of the horizontal splicing board 44. By adjusting the position and quantity of the horizontal splicing board 44, users can precisely control the distance between two groups of classification boards 43, thereby realizing a more detailed and personalized partition storage solution. Whether it is necessary to isolate large instruments separately or to closely arrange small parts, this design can easily handle it, greatly enhancing the flexibility and practicality of the storage system.

[0043] In summary, the classification mechanism 4 not only meets the storage needs of different items but also ensures the orderly and convenient separation and placement of instruments through a flexible adjustment mechanism, bringing great convenience to the daily work and life of users.

[0044] Specifically, sliders 22 are installed at both ends of the device body 1, and the sliders 22 are internally movably connected to sliding balls 23. By installing a placement table 21 at both ends of the device body 1, the placement table 21 slides up and down and is lifted and lowered inside the movable base 31, and the sliding balls 23 make the device body 1 rise and fall more smoothly.

[0045] As can be seen from the above, one end of the first folding rod 36 is rotatably connected to the second folding rod 37, and a top plate 38 is set at the upper end of the second folding rod 37. The rotation of the rotating rod 35 drives the first folding rod 36 to cooperate with the second folding rod 37 to produce a folding rod effect, so that the second folding rod 37 pulls the top plate 38 up and down to move up and down, and a pillar 39 is installed at the upper end of the top plate 38, so that the pillar 39 is connected to the bottom of the device body 1.

[0046] refer to Figure 5 As shown, the upper end of the top plate 38 is fixedly connected to the pillar 39, and the upper end of the pillar 39 fits with the bottom groove of the device body 1. The positioning column 308 is inserted inside the top plate 38. The pillar 39 is installed at the upper end of the top plate 38, so that the pillar 39 is connected to the bottom of the device body 1. The pillar 39 and the device body 1 can be disassembled. The positioning column 308 is inserted inside the top plate 38, so that the top plate 38 is supported and guided by the positioning column 308 when it is raised and lowered to prevent deviation. The top plate 38 is the key supporting structure of the entire device, and its design details reflect the dual pursuit of stability and flexibility. The upper end of the top plate 38 is firmly connected to the pillar 39. This connection is not only stable, but also easy to install and maintain. The upper end of the pillar 39 is cleverly matched with the groove at the bottom of the device body 1, forming a connection method that is both tight and easy to disassemble. This design allows the user to easily separate the device body 1 from the top plate 38 and the pillar 39 when necessary, which is convenient for transportation, storage or internal maintenance.

[0047] The top plate 38 is cleverly designed with a slot for the positioning column 308. The positioning column 308, as a precise guiding element, not only enhances the stability of the top plate 38 during the lifting process, but also ensures its precise movement in the vertical direction. When the top plate 38 is lifted up and down, the positioning column 308 acts as a precise guide rail to guide and support the movement of the top plate 38, effectively preventing any possible deviation or shaking. This design not only improves the stability of the overall structure, but also ensures the accuracy and reliability of the device during long-term use.

[0048] In addition, the use of the positioning posts 308 provides additional convenience for the user. When adjusting the height of the top plate 38 to adapt to different working environments or storage requirements, the user can simply adjust the position or number of the positioning posts 308 to optimize the support structure and ensure that the top plate 38 always remains in the ideal position. This flexibility and adjustability makes the entire device more adaptable to a variety of application scenarios, further enhancing its practical value.

[0049] Specifically, four groups of positioning columns 308 are installed. The outer surface of the positioning column 308 is in sliding fit with the inner wall of the top plate 38. Two groups of the first folding rod 36 and the second folding rod 37 are installed. The lower end of the first folding rod 36 is matched with the rotating rod 35. An inner plate 33 is installed inside the moving base 31. A driving member 34 is installed at the upper end of the inner plate 33. When the driving member 34 is started, the rotating rod 35 is driven to rotate, and the rotation of the rotating rod 35 drives the first folding rod 36 to cooperate with the second folding rod 37 to produce a folding rod effect.

[0050] Embodiment 2:

[0051] Reference Figures 1-6 As shown, the two ends of the classification plate 43 are inserted with horizontal splicing plates 44. The lower end of the moving base 31 is connected to the bottom sliding plate 45. The lower end of the bottom sliding plate 45 is movably connected to the folding wheel 46. The two ends of the classification plate 43 are attached to the magnetic attraction grooves 42. Multiple groups of slots are opened at the two ends of the classification plate 43. The two ends of the horizontal splicing plate 44 are attached to the slots on the outer surface of the classification plate 43. The upper end of the folding wheel 46 is in rotational fit with the bottom sliding plate 45. By installing a classification mechanism 4 inside the device main body 1, and installing multiple groups of storage boxes 41 inside the device main body 1, and the sizes of the storage boxes 41 are different, different-sized items can be placed. Multiple groups of magnetic attraction grooves 42 are opened inside the storage boxes 41, and the classification plate 43 can be inserted into the magnetic attraction grooves 42 to adjust the space inside the storage boxes 41. At the same time, multiple groups of slots are opened at the two ends of the classification plate 43, so that by adjusting the horizontal splicing plate 44, the interval between the two classification plates 43 can be controlled, and the instruments can be separated and placed, which is convenient for classification and taking, and improves the efficiency of taking and placing. By installing the bottom sliding plate 45 at the lower end of the moving base 31, the folding wheel 46 can be rotatably folded into the bottom sliding plate 45.

[0052] As can be seen from the above, the lower end of the first folding rod 36 of the screen is matched with the upper end of the roller top plate 38. Four groups of roller top plates 38 are installed. Four groups of roller top plates 38 are installed at the lower end of the first folding rod 36 of the screen, making the screening action of the first folding rod 36 of the screen smoother. The device main body 1 can be disassembled from the support column 39. After disassembly, the folding wheel 46 is folded through the bottom sliding plate 45 to save the placement space.

[0053] Embodiment 3:

[0054] Reference Figures 1-6As shown, the guard plate 32 is made of aluminum alloy. The inner wall of the guard plate 32 fits against the outer surface of the moving base 31. By installing the convenient removal mechanism 3 at the lower end of the device body 1 and installing the guard plate 32 on the outside of the moving base 31, since the guard plate 32 is made of aluminum alloy, the protection and anti-collision property of the outer surface of the moving base 31 itself is stronger. By carefully installing the guard plate 32 on the outside of the moving base 31, this design not only enhances the overall aesthetics of the device, but also takes an important step in practicality. The guard plate 32 is made of high-quality aluminum alloy. Aluminum alloy, with its excellent strength, light weight and good corrosion resistance, becomes an ideal material to protect the moving base 31 from external damage.

[0055] The addition of the aluminum alloy guard plate 32 significantly improves the protection ability of the outer surface of the moving base 31. In daily use, whether it is accidental collision, friction or other forms of physical impact, the guard plate 32 can effectively absorb and disperse these forces, thus protecting the moving base 31 from damage. This protective effect not only extends the service life of the device, but also ensures its stable operation in various complex environments.

[0056] In addition, the aluminum alloy guard plate 32 also gives the moving base 31 stronger anti-collision property. When handling, moving or adjusting the position of the device, even if an accidental collision occurs, the guard plate 32 can effectively reduce or avoid the damage to the moving base 31 by virtue of its solid texture and excellent impact resistance. This design not only improves the safety of the device.
