Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a multifunctional gastrointestinal endoscopy nursing cart. Background Technology

[0002] In modern medicine, gastroscopy and colonoscopy are important diagnostic tools for digestive tract diseases. The accompanying multi-functional nursing carts frequently move between examination rooms and wards, typically storing endoscopy equipment, biopsy instruments, sterilization supplies, and refrigerated medications. Because these carts may tilt during movement due to uneven ground, uneven load distribution, or external impacts, this can lead to items slipping or, in severe cases, equipment damage or medication failure. Therefore, a high degree of stability against tipping is required for these nursing carts.

[0003] Currently, most anti-tipping designs for existing gastrointestinal endoscopy care carts use fixed counterweights or simple mechanical limiting structures. These solutions have significant shortcomings: when the care cart tilts, the fixed counterweights cannot dynamically adjust the center of gravity according to the tilt direction, and the mechanical limiting structures have a delayed response and limited adjustment range, making it difficult to generate an effective reverse stabilizing torque in the early stages of tipping, resulting in poor anti-tipping performance.

[0004] Therefore, a multi-functional gastrointestinal endoscopy nursing vehicle is proposed to address the aforementioned issues. Summary of the Invention

[0005] To overcome the above shortcomings, the present invention provides a multifunctional gastrointestinal endoscopy care cart, which aims to improve the problem that the anti-rollover structure of some care carts in the prior art is difficult to dynamically adjust the center of gravity and has a slow response, resulting in poor anti-rollover effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multifunctional gastrointestinal endoscopy nursing cart includes a frame, the top of which is equipped with a small item storage platform and a disinfection lamp, the middle layer of which is equipped with a refrigerator and partitions, the bottom layer of which is equipped with multiple drawers, and the bottom of the partitions is equipped with an anti-tipping mechanism.

[0008] The anti-rollover mechanism includes a trigger, a locking component, a transmission component, and a balance box. The top of the trigger is located at the bottom of the partition, the locking component is located at the bottom of the partition, the transmission component is located on the inner wall of the bottom of the frame, and the balance box is located at the bottom of the frame.

[0009] The balance box includes a box shell, the top of which is fixedly connected to the bottom of the frame. Slide rails are fixedly connected to both sides of the frame. Multiple sets of ball bearings are provided on the inner side of the slide rails. Counterweight block two is slidably connected to the inner side of the two slide rails. A movable plate is fixedly connected to the top center of counterweight block two.

[0010] As a further description of the above technical solution:

[0011] Multiple return springs are fixedly connected to both sides of the housing, and a push plate is fixedly connected to the other end of each return spring.

[0012] As a further description of the above technical solution:

[0013] The trigger includes two L-shaped fixed platforms, the tops of which are fixedly connected to the bottom of the partition. A counterweight is slidably connected to the top of the L-shaped fixed platforms, and the counterweight is used to sense the tilt state of the nursing cart.

[0014] As a further description of the above technical solution:

[0015] One end of the counterweight is fixedly connected to a constant force spring, and the other end of the constant force spring is fixedly connected to the inside of the L-shaped fixed platform. Two fixed pulleys are fixedly connected to the bottom of the partition. A pull rope is fixedly connected to the top of the counterweight. The outside of the pull rope is sleeved on the outside of the fixed pulley, and the other end of the pull rope is fixedly connected to a sliding rod. A lifting block is fixedly connected to the bottom of the sliding rod.

[0016] As a further description of the above technical solution:

[0017] The locking element includes a slide block and a guide block. The top of the slide block is fixedly connected to the bottom of the partition, the guide block is fixedly connected to the top of the slide block, and the outer side of the sliding rod is slidably connected to the inside of the guide block.

[0018] As a further description of the above technical solution:

[0019] The bottom of the slide block is slidably connected to two sliding plates. Clamping columns are fixedly connected to the bottom of the two sliding plates on the same side. Rotating piles are provided on the same side of the sliding plates. A connecting rod is rotatably connected to the inner side of the rotating pile. The other end of the connecting rod is rotatably connected to the top inner side of the lifting block.

[0020] As a further description of the above technical solution:

[0021] The transmission component includes a fixed post and a sleeve. The bottom of the fixed post is fixedly connected to the bottom inner wall of the frame, and the sleeve is fixedly connected to the adjacent side of the fixed post. A telescopic rod is slidably connected to the inner side of the sleeve.

[0022] As a further description of the above technical solution:

[0023] The telescopic rod has a contact head fixedly connected to one end of each other. The two contact heads are at the same horizontal line as the movable plate. The other end of the telescopic rod is fixedly connected to a starting spring. The other end of the starting spring is fixedly connected to the inner wall of the sleeve. The other end of the telescopic rod is fixedly connected to a start / stop ring. The extended end of the start / stop ring is slidably connected to the outside of the sleeve and contacts the side of the locking pin that is close to it.

[0024] The present invention has the following beneficial effects:

[0025] 1. In this invention, by sliding the counterweight block one in the triggering component, the pull rope, sliding rod and lifting block are driven to move, the locking component locks the transmission component, and the starting spring pushes the telescopic rod to drive the contact head, movable plate and counterweight block two to slide along the slide rail. This realizes that when the nursing cart is tilted, the center of gravity shifts rapidly in the opposite direction, generating a reverse torque to resist the tipping tendency, effectively improving the stability of the nursing cart and avoiding the beneficial effect of tipping.

[0026] 2. In this invention, the constant force spring pushes the counterweight block one to reset, causing the sliding rod, lifting block and sliding plate to move in the opposite direction, so that the clamping column pushes the start-stop ring to retract the telescopic rod. At the same time, the reset spring pushes the push plate and the second counterweight block back to the initial position, so as to realize the precise reset of each structure after the nursing cart is straightened, restore the initial center of gravity distribution, ensure the continuous and stable operation of the anti-rollover mechanism, and improve the reliability of the cyclic operation.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Reference Figures 1 to 8 This invention provides an embodiment of a multifunctional gastrointestinal endoscopy nursing cart, comprising a frame 1. The frame 1 serves as the main support frame of the nursing cart, bearing all functional components of the top, middle, and bottom layers, as well as an anti-tipping mechanism 7, ensuring overall structural stability. The top of the frame 1 is equipped with a small item storage platform 2 and a disinfection lamp 3. The storage platform 2 provides flat space for storing small nursing tools commonly used during gastrointestinal endoscopy examinations, facilitating quick access by medical staff. The disinfection lamp 3 disinfects the surface of the storage platform and the surrounding air by emitting ultraviolet light or light of a specific wavelength, ensuring a hygienic and safe medical operating environment. The middle layer of the frame 1 is equipped with a refrigerator 4 and partitions 6. The refrigerator 4 maintains a low-temperature environment for storing medications, reagents, or biological samples requiring refrigeration during gastrointestinal endoscopy examinations, preventing their deterioration and inactivation.

[0039] The partition 6 is horizontally fixed to the middle layer of the frame 1, dividing the middle space into upper and lower areas. The upper area is used to install the refrigerator box 4, while the lower area provides a mounting base for the trigger 71 and locking element 72 of the anti-rollover mechanism 7, optimizing the space layout. The bottom layer of the frame 1 has multiple drawers 5, which form multiple independent storage spaces through a layered design, allowing for the categorized storage of gastrointestinal endoscope accessories, record forms, etc., facilitating standardized management. The bottom of the partition 6 is equipped with the anti-rollover mechanism 7, which is integrated between the bottom of the partition 6 and the bottom of the frame 1. Through mechanical linkage, it adjusts the center of gravity when the nursing cart tilts.

[0040] The anti-rollover mechanism 7 includes a trigger 71, a locking element 72, a transmission element 73, and a balance box 74. The top of the trigger 71 is located at the bottom of the partition 6, the locking element 72 is located at the bottom of the partition 6, the transmission element 73 is located on the inner wall of the bottom of the frame 1, and the balance box 74 is located at the bottom of the frame 1.

[0041] The balance box 74 includes a box shell 741, which is a closed structure and is fixedly connected to the bottom of the frame 1 at the top. The shell houses components such as slide rails 742, counterweight 744, and return spring 746, providing protection and limiting movement space. Slide rails 742 are fixedly connected to both sides of the frame 1. Multiple sets of ball bearings 743 are arranged inside the slide rails 742, forming a rolling friction pair to reduce the resistance when the counterweight 744 slides, ensuring its responsiveness. The counterweight 744 is slidably connected to the inner side of the two slide rails 742. The counterweight 744 is connected to the contact head 734 of the telescopic rod 733 via a movable plate 745 fixedly connected to the top center. When tilted, it slides in the opposite direction along the slide rails 742 under thrust, increasing the weight distribution in the reverse tilting direction of the nursing cart and adjusting the overall center of gravity. Multiple return springs 746 are fixedly connected to the other two sides of the housing 741. The two ends of the return springs 746 are connected to the housing 741 and the push plate 747 respectively. When the counterweight 744 slides, it compresses the spring to store potential energy. After returning to the center, the spring releases the potential energy and pushes the counterweight 744 back to the initial center position through the push plate 747, preparing for the next anti-rollover.

[0042] The trigger 71 includes two L-shaped fixed platforms 711. The two L-shaped fixed platforms 711 have an L-shaped structure, with their tops fixedly connected to the bottom of the partition 6, their vertical ends fixed to the bottom of the partition 6, and their horizontal ends forming a transverse slide rail 742, providing a guide rail for the counterweight 713 to slide laterally along the frame 1. The counterweight 713 is slidably connected to the top of the L-shaped fixed platform 711. The counterweight 713 has a uniform mass distribution and senses the tilt of the nursing cart through its own weight. When the nursing cart tilts, it slides along the tilt direction to trigger the subsequent mechanism. A constant force spring 712 is fixedly connected to one end of the counterweight 713, and the other end of the constant force spring 712 is fixedly connected to the inside of the L-shaped fixed platform 711, providing a constant pulling force. When horizontal, the counterweight 713 is maintained in its initial position; when tilted, it is overcome by the component of gravity, and after returning to the upright position, the counterweight 713 is pulled back to its original position. Two fixed pulleys 714 are fixedly connected to the bottom of the partition 6. The fixed pulleys 714 change the direction of force on the pull rope 715, converting the lateral sliding displacement of the counterweight 713 into the vertical movement of the sliding rod 716. The top of the counterweight 713 is fixedly connected to the pull rope 715, which is sleeved on the outside of the fixed pulleys 714. The other end of the pull rope 715 is fixedly connected to the sliding rod 716. The displacement is transmitted through the fixed pulleys 714, and the trigger signal is transmitted to the locking member 72. The bottom of the sliding rod 716 is fixedly connected to the lifting block 717. When the sliding rod 716 slides vertically along the guide block 722, the lifting block 717 converts the vertical displacement into lateral thrust through its geometric structure, which is used to drive the sliding plate 723 of the locking member 72.

[0043] The locking element 72 includes a slide block 721 and a guide block 722. The top of the slide block 721 is fixedly connected to the bottom of the partition 6, serving as the mounting base for the locking element 72 and providing a horizontal sliding track to support the reciprocating motion of the sliding plate 723. The guide block 722 is fixedly connected to the top of the slide block 721 and has a through hole inside to provide vertical sliding guidance for the sliding rod 716, ensuring its stable movement trajectory. The outer side of the sliding rod 716 is slidably connected inside the guide block 722. The bottom of the slide block 721 is slidably connected to two sliding plates 723. Clamping posts 724 are fixedly connected to the bottom of the two sliding plates 723 on the same side. The locking and unlocking of the start-stop ring 735 is achieved by the movement of the two clamping posts 724. Rotating posts 725 are provided on the adjacent side of the sliding plates 723. A connecting rod 726 is rotatably connected to the inner side of the rotating post 725. The other end of the connecting rod 726 is rotatably connected to the top inner side of the lifting block 717. The connecting rod 726 converts the vertical movement of the lifting block 717 into the lateral separation or closing action of the sliding plate 723 through the lever principle.

[0044] The transmission component 73 includes a fixed post 731 and a sleeve 732. The bottom of the fixed post 731 is fixedly connected to the bottom inner wall of the frame 1, serving as a support base for the sleeve 732 and ensuring the installation rigidity of the transmission component 73. The sleeve 732 is fixedly connected to the side of the fixed post 731, forming a linear guide rail on its inner side. A telescopic rod 733 is slidably connected to the inner side of the sleeve 732. The telescopic rod 733 slides along the sleeve 732. When the lock is released, it extends towards the movable plate 745 under the action of the starting spring 736 to transmit power. When locked, the telescopic rod 733 retracts into the sleeve 732. A contact head 734 is fixedly connected to the adjacent end of the telescopic rod 733. The two contact heads 734 are on the same horizontal line as the movable plate 745. After contact, they push the movable plate 745 and the counterweight 744 to slide, realizing the power transmission for center of gravity adjustment. A starting spring 736 is fixedly connected to the other end of the telescopic rod 733. The other end of the starting spring 736 is fixedly connected to the inner wall of the sleeve 732. When horizontal, it is compressed and stores elastic potential energy. When the lock is released, it releases energy and pushes the telescopic rod 733 to slide rapidly towards the movable plate 745. A start-stop ring 735 is fixedly connected to the outer side of the other end of the telescopic rod 733. The extended end of the start-stop ring 735 is slidably connected to the outer side of the sleeve 732. Its annular protrusion cooperates with the clamping post 724 of the locking member 72, and the locking and unlocking states of the transmission member 73 are switched through mechanical limiting.

[0045] Working Principle: When the nursing cart is in a horizontal, stationary state, the trigger 71, locking element 72, transmission element 73, and balance box 74 in the anti-rollover mechanism 7 are all in their initial positions. Counterweight 713, under the action of the constant force spring 712, is located at the edge of the L-shaped fixed platform 711, while the sliding rod 716 and lifting block 717 are at their lowest points. The two sliding plates 723 of the locking element 72 remain relatively stationary under the support of the connecting rod 726. The clamping column 724 is in contact with the start / stop ring 735, causing the telescopic rod 733 to be in a retracted state, and the starting spring 736 to be in a compressed, energy-storing state. The contact head 734 maintains a certain distance from the movable plate 745. Counterweight 744 of the balance box 74, under the action of the return spring 746 and the push plate 747, is located in the middle position of the slide rail 742, and the overall center of gravity of the nursing cart is located at its geometric center.

[0046] When the nursing cart tilts due to an external force, the trigger 71 responds first. The counterweight 713 in the tilting direction overcomes the reverse force of the constant force spring 712 under the action of gravity and slides along the L-shaped fixed platform 711 in the tilting direction. For example, when the nursing cart tilts to the left, the counterweight 713 on the left slides to the left, while the counterweight 713 on the right remains relatively stationary due to gravity and the constraint of the constant force spring 712.

[0047] The sliding of counterweight 713 causes the pull rope 715 to move. The pull rope 715 changes direction via the fixed pulley 714, pulling the sliding rod 716 upward along the guide block 722. The lifting block 717 at the bottom of the sliding rod 716 rises accordingly, pushing the two sliding plates 723 to slide in opposite directions via the connecting rod 726, causing the clamping column 724 to disengage from the start / stop ring 735. At this time, the locking member 72 releases its lock on the transmission member 73.

[0048] After the lock is released, the spring 736 releases its elastic potential energy, pushing the telescopic rod 733 to slide along the sleeve 732 towards the movable plate 745. The contact head 734 at the end of the telescopic rod 733 contacts the movable plate 745, pushing the movable plate 745 and the connected counterweight 744 to slide along the slide rail 742. The ball bearings 743 on the inner side of the slide rail 742 reduce sliding friction, ensuring that the counterweight 744 can respond quickly.

[0049] Counterweight 744 slides in the opposite direction of the tilt. For example, when the trolley tilts to the left, counterweight 744 slides to the right, causing the overall center of gravity of the trolley to shift to the right. During this process, the return spring 746 on the other side of the housing 741 is compressed, storing elastic potential energy. The shift in the center of gravity generates a torque opposite to the tilt direction, resisting the tendency to tip over and allowing the trolley to gradually regain balance.

[0050] As the nursing cart gradually returns to its upright position, the gravitational component of the counterweight 713 on the trigger 71 decreases, and the constant force spring 712 pushes the counterweight 713 to slide back to its initial position. The sliding rod 716 and the lifting block 717 descend under gravity, causing the sliding plate 723 to slide in the opposite direction via the connecting rod 726. The clamping column 724 then moves closer to the start-stop ring 735. Once the nursing cart is fully upright, the clamping column 724 applies a pushing force to the start-stop ring 735, causing the telescopic rod 733 to retract to its initial position. Simultaneously, the compressed return spring 746 in the balance box 74 pushes the push plate 747 and the second counterweight 744 back to their initial positions, restoring the nursing cart to its horizontal center of gravity distribution.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
