Description

Technical Field

[0001] The present invention relates to the technical field of medical supporting equipment, and in particular to a modular expansion device for a medical transport vehicle. Background Art

[0002] In the field of medical transportation, medical transport vehicles play a vital role. They are responsible for transferring patients from one location to another safely and quickly, and they also need to carry various medical equipment, medicines and first aid supplies to ensure the safety and health of patients during transportation. However, traditional medical transport vehicles have gradually exposed many limitations in practical applications, prompting the demand for new modular expansion devices.

[0003] On the one hand, the storage space layout of traditional medical transport vehicles is often relatively fixed. The vehicle is usually only equipped with simple shelves or small lockers, and its space size and shape are difficult to flexibly adjust according to different medical tasks. For example, when dealing with the transfer of ordinary patients, it may barely meet the placement needs of basic medical supplies; but when facing major accidents or emergency rescue scenarios, it is necessary to carry a large number of large medical equipment such as defibrillators, ECG monitors, oxygen cylinders, and a variety of first aid medicines, there will be a serious shortage of storage space. This not only limits the amount of medical resources that the transport vehicle can carry, but also may affect the medical staff's rapid access to equipment and medicines in emergency situations due to the disorderly placement of items, thereby delaying the patient's treatment.

[0004] To this end, we propose a modular expansion device for a medical transport vehicle to solve the above problems. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. A fixed frame is installed on the fixed truss on the frame of the transfer vehicle, and the telescopic storage rack is connected with a locking plate and a quick-release assembly, thereby realizing modular installation of the storage rack. This enables the device to flexibly adjust the number and position of the storage rack according to actual needs, effectively improving the space utilization rate of the transfer vehicle and meeting the diverse requirements of storage space for different medical tasks.

[0018] 2. The fastening plate and telescopic plate of the telescopic rack are connected by a unique telescopic component, which can easily adjust the size of the rack. It can be retracted to save space when placing small medical items, and can be extended when larger equipment or more items need to be placed. This greatly enhances the adaptability of the rack to items of different sizes, allowing the transfer vehicle to carry more types of medical supplies. When the telescopic rack is not needed or the medical items are placed, the mounting frame and the telescopic rack are moved under the transfer lathe bed through the telescopic cylinder to avoid inconvenience in transportation caused by the overall width of the transfer vehicle being too large.

[0019] 3. The quick-release assembly uses a clever combination of fixed columns, rotating limit rings, arc-shaped limit holes, limit columns and card-mounted frames to achieve rapid connection and separation of the fastening plate and the locking plate. Medical staff only need to operate the connecting column to drive the push frame to move, and they can easily complete the installation or removal of the telescopic rack without the need for complex tools, saving time and energy. Especially in emergency rescue missions, they can respond quickly and improve work efficiency. The principle of the entire installation and removal process is relatively simple, and the operating steps are clear and concise. After simple training, medical staff can master it proficiently. This reduces errors or delays that may be caused by complex operations, and further ensures the timeliness and accuracy of medical transportation.

[0020] 4. The telescopic rack can conveniently place instruments and form simple functional modules, such as vital signs monitoring module and first aid module. This effectively expands the function of the transport vehicle, and can monitor vital signs or provide emergency treatment in real time during the patient transport process, improving the medical security capabilities during the transport process and providing more comprehensive support for the patient's life safety.

[0021] 5. The locking assembly uses a fixed semicircular ring, a rotating clamp and a locking screw to firmly mount the locking plate on the mounting column. It can withstand heavy weight and external force impact, ensuring the stability of the telescopic shelf during use. Even when the transport vehicle is driving at high speed or emergency braking, the shelf will not shake or fall off easily, providing a safe support environment for the medical items and equipment placed on it.

[0022] 6. The synergy between the connecting column, the push frame, the L-shaped rotating frame and the fixing components on the limit frame further enhances the stability of the connection between the fastening plate and the locking plate. This multiple locking mechanism effectively prevents the connection from loosening due to long-term use or severe vibration, ensures the reliability of the entire device during the entire medical transport process, and reduces the safety hazards caused by device failure.

[0023] In summary, the present invention can realize flexible use of space, modular and telescopic design of the storage rack, adapt to various items, convenient installation and disassembly, easy operation of quick-release components, construct functional modules and be shock-resistant, ensure equipment stability, improve the function and reliability of the transfer vehicle, and help medical transfer to be carried out efficiently and safely.

[0039] A connecting column 15 is commonly installed at the upper ends of multiple pushing frames 22 with corresponding positions, and an L-shaped rotating frame 16 is installed on the connecting column 15. The upper end surface of the locking plate 7 is fixedly connected to the limiting frame 8, and the L-shaped rotating frame 16 is fixed to the limiting frame 8 through a fixing component. The fixing component includes a movable plate 10, and the movable plate 10 is installed on the limiting frame 8 through a plurality of locking springs 17. A plurality of fixed through holes and a plurality of fixed grooves 23 are symmetrically provided on the limiting frame 8, and each of the fixed grooves 23 is connected to the fixed through hole with corresponding position, and the L-shaped rotating frame 16 is clamped in one of the fixed grooves 23, a supporting groove is provided on the side wall of the L-shaped rotating frame 16, and a plurality of fixed blocks 24 are symmetrically installed on the side wall of the movable plate 10, and one of the fixed blocks 24 is clamped in the supporting groove.

[0040] The telescopic storage rack includes a symmetrically arranged fastening plate 6 and a telescopic plate 4, the fastening plate 6 is connected to a locking plate 7, a telescopic bearing net 5 is installed between the fastening plate 6 and the telescopic plate 4, two telescopic components are symmetrically installed between the fastening plate 6 and the telescopic plate 4, each telescopic component includes two symmetrically arranged connecting vertical frames 9, and one of the connecting vertical frames 9 is fixedly installed on the side wall of the fastening plate 6, and the other connecting vertical frame 9 is fixedly installed on the side wall of the telescopic plate 4, each end of each connecting vertical frame 9 is rotatably connected to a first telescopic rod 11, and one of the first telescopic rods 11 is fixedly installed on the side wall of the telescopic plate 4. 1 is located at the upper end of the connecting vertical frame 9, and another first telescopic rod 11 is located at the lower end of the connecting vertical frame 9, the two first telescopic rods 11 are centrally symmetrically arranged, the other end of each connecting vertical frame 9 away from the first telescopic rod 11 is rotatably connected to the second telescopic rod 12, and the other end of each second telescopic rod 12 is rotatably connected to the end of the other first telescopic rod 11; each second telescopic rod 12 is rotatably connected to the end of the corresponding connecting vertical frame 9 away from the corresponding position of the connecting vertical frame 9, and each connecting rod 13 is rotatably connected to the middle part of the first telescopic rod 11 at the corresponding position.

[0041] Installation of the telescopic storage rack: multiple locking plates 7 are fixed to the mounting column 3 through the locking assembly. During the specific operation, the fixed semicircular ring 18 is fixed in the mounting buffer groove 20 of the locking plate 7, and the rotating clamping ring 19 is rotatably connected to the fixed semicircular ring 18. After the two are clamped on the mounting column 3, the locking screw 21 is used to lock the fixed semicircular ring 18 and the rotating clamping ring 19, so that the locking plate 7 is stably installed on the mounting column 3.

[0042] Then, the fastening plate 6 of the telescopic storage rack is connected to the locking plate 7 by using a quick-release assembly. When the fastening plate 6 and the locking plate 7 need to be connected or separated, an external force acts on the connecting column 15 to cause it to move in the vertical direction. Since the connecting column 15 is connected to the pushing frame 22, the vertical movement of the connecting column 15 will drive the pushing frame 22 to slide vertically in the vertical groove 25 synchronously. A plurality of groups of first gear teeth are provided on the side wall of the pushing frame 22, and a plurality of second gear teeth are provided on the outer side wall of the rotation limit ring 27, and each group of first gear teeth can mesh with the corresponding second gear teeth on the rotation limit ring 27. The first gear of the push frame 22 interacts with the second gear of the rotation limit ring 27 when the push frame 22 slides up and down, thereby driving the rotation limit ring 27 to rotate around its own axis. A plurality of arc-shaped limit holes 28 are symmetrically provided on the rotation limit ring 27, and a plurality of limit posts 33 are slidably connected on the inner wall of the extension groove 26. Each limit post 33 is slidably connected in the corresponding arc-shaped limit hole 28. When the rotation limit ring 27 rotates, the shape and position changes of the arc-shaped limit hole 28 guide the limit post 33 to perform corresponding sliding movement along the arc trajectory. A clamping frame 29 is installed on the limit post 33, and an annular groove 31 is provided on the outer wall of the fixed post 30. In the initial state or during operation, as the limit post 33 moves driven by the arc-shaped limit hole 28, the clamping frame 29 changes its position accordingly, thereby realizing the clamping or disengagement action with the annular groove 31. When the card frame 29 is inserted into the annular groove 31, the connection operation between the fastening plate 6 and the locking plate 7 is completed, so that the telescopic storage rack can be firmly installed on the locking plate 7; and when the card frame 29 is disengaged from the annular groove 31, the separation of the two is achieved, which facilitates the disassembly and other operations of the telescopic storage rack.

[0043] The upper ends of the plurality of push frames 22 are connected to the L-shaped rotating frame 16. After the connection operation is completed, the L-shaped rotating frame 16 will be located at a specific position of the limiting frame 8. The limiting frame 8 is provided with a movable plate 10 through a plurality of locking springs 17, and the limiting frame 8 itself is provided with a plurality of fixing through holes and a plurality of fixing grooves 23. Each fixing groove 23 is interconnected with a corresponding fixing through hole, and the L-shaped rotating frame 16 will be stuck in one of the fixing grooves 23. At the same time, a plurality of fixing blocks 24 are symmetrically installed on the side wall of the movable plate 10. After the L-shaped rotating frame 16 is stuck in the fixing groove 23, the fixing blocks 24 of the movable plate 10 will be inserted into the abutting grooves on the side wall of the L-shaped rotating frame 16 under the elastic force of the locking springs 17. The mutual engagement of the fixing block 24 and the abutment groove, as well as the continuous elastic force provided by the locking spring 17, can effectively limit the accidental movement of the L-shaped rotating frame 16, thereby ensuring that the pushing frame 22 and other related components remain in the appropriate position, so that the entire connection structure is in a stable state, preventing the connection between the fastening plate 6 and the locking plate 7 from loosening due to factors such as vibration during the travel of the transfer vehicle, thereby ensuring the firmness of the installation of the telescopic storage rack and the safety during use.

[0044] When the space size of the telescopic shelf needs to be adjusted, the telescopic assembly comes into play, the connecting vertical frame 9 connects the fastening plate 6 and the telescopic plate 4 respectively, the first telescopic rod 11 is rotatably connected to the connecting vertical frame 9 and is symmetrically distributed up and down, the second telescopic rod 12 is connected between the two first telescopic rods 11 and the connecting vertical frame 9, and the connecting rod 13 is connected to the middle of the second telescopic rod 12 and the first telescopic rod 11. By changing the relative angle and position relationship between the first telescopic rod 11 and the second telescopic rod 12, under the coordinated action of multiple such telescopic assemblies, the telescopic plate 4 can be made to perform a stable telescopic movement relative to the fastening plate 6, thereby driving the telescopic bearing net 5 to expand or contract to meet the placement requirements of items of different sizes, and realize flexible adjustment of the storage space. During the transportation process, the items are placed on the telescopic bearing net 5, and the entire device provides a convenient and adjustable storage solution for medical transportation, ensuring the orderly storage and transportation of medical supplies during the transportation process.

[0045] When using the telescopic shelf to build a vital signs monitoring module:

[0046] First, vital signs monitoring instruments such as ECG monitors, blood pressure monitors, and blood oxygen saturation monitors are placed on the telescopic bearing net 5. These instruments can be placed in a suitable space on the telescopic bearing net 5 by adjusting the distance between the telescopic plate 4 and the fastening plate 6 according to their own size and shape. Then, inside the vital signs monitoring module, each instrument is fixed with an elastic fixing belt. The elastic fixing belt has a certain elasticity, which can not only tightly bind the instrument, but also buffer vibration to a certain extent. For example, an ECG monitor may be cross-fixed by multiple elastic fixing belts, which pass around the instrument body and are fastened to the corresponding fixing points on the fastening plate 6 or the telescopic plate 4.

[0047] At the same time, buffer pads are laid at the contact points between the instrument and the telescopic bearing net 5 and the surrounding structure. The buffer pads are generally made of materials with good shock absorption properties such as rubber, silicone or high-density foam. For example, a rubber buffer pad of a suitable shape is placed at the bottom of the blood pressure monitor to prevent the bottom of the instrument from being hit hard due to bumps, and buffer pads are also set at the sides of the instrument where they may contact and collide with other components to protect the instrument in all directions.

[0048] When building the first aid module: place the defibrillator, first aid medicine storage box, simple respirator and other first aid equipment on the telescopic shelf. After the defibrillator is placed in the appropriate position, it is also firmly fixed with an elastic fixing belt. The fixing belt passes through the handle of the defibrillator or the fixing ring of the fuselage and is fixed to the corresponding position of the shelf. At the electrode plate of the defibrillator, special attention should be paid to avoid the fixing belt from blocking or affecting its normal use function. At the same time, cushion pads are placed under and around it to prevent damage to the electrode plate. The medicines inside the first aid medicine storage box are prevented from shaking in the box by means of compartments and fixing clips, and the storage box as a whole is fixed to the shelf by an elastic fixing belt. Buffer pads are laid at the bottom and around the storage box to reduce the impact of vibration on the packaging and quality of the medicines. The simple respirator is also fixed to a specific position on the shelf by an elastic fixing belt. Its parts such as the mask that contact the human body are protected by a special protective cover or cushioning material to prevent scratches or damage due to vibration during transportation. At the same time, cushion pads are arranged around the main part of the respirator to ensure that its normal function is not affected by bumps.

[0049] Through these measures, both the vital signs monitoring module and the first aid module, after being installed on the telescopic rack of the medical transport vehicle, can effectively resist bumps during the vehicle's driving, ensure the safety, stability and normal use of the internal equipment at any time, and provide reliable protection for the treatment of patients during medical transport.

[0050] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
