Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, in particular to a posture assisting device for thoracic surgery nursing. Background Art

[0002] The Positioning Assist Device for Thoracic Surgery Nursing is a bed specially designed for thoracic surgery patients, aiming to provide patients with the best nursing experience and rehabilitation support. The design of the bed fully considers the special needs of thoracic surgery patients and provides a variety of position adjustment functions to help patients maintain the correct position during postoperative recovery and effectively reduce the occurrence of complications; this bed has basic lifting and tilting functions. At the same time, the bed adopts an ergonomic design to provide comfortable support and avoid problems such as pressure sores caused by long-term bed rest; in addition, the Positioning Assist Device for Thoracic Surgery Nursing also has good stability and mobility, and is suitable for hospital wards, ICUs and other environments. Its sturdy structure and easy-to-operate adjustment system enable nursing staff to easily adjust the various parameters of the bed to meet the nursing needs of different patients. This bed integrates a variety of modern nursing functions to provide a safe and comfortable rehabilitation environment for patients after thoracic surgery.

[0003] First, in thoracic surgery nursing, the patient's position needs to be adjusted frequently, especially when the position assist device is used for extended use. Traditional equipment often cannot ensure the synchronization of support on both sides. This asynchrony may cause the device to tilt or become unstable during the extension process, which in turn affects the patient's safety and comfort, and may even increase the risk during the nursing process. Therefore, how to achieve synchronous support of the device during expansion has become a technical problem that needs to be solved urgently;

[0004] Secondly, thoracic surgery patients may need mobility assistive devices during the nursing process. During the movement, the equipment may encounter uneven ground or sudden vibration. Traditional nursing devices usually lack effective shock absorption mechanisms. The vibration force is directly transmitted to the equipment and the patient, causing the equipment to be unstable and affecting the patient's comfort. This situation not only affects the nursing effect, but may also aggravate the patient's discomfort. Therefore, how to effectively absorb and alleviate the vibration force is an urgent problem to be solved in the design of the device.

[0005] Finally, in thoracic surgery nursing, different patients have different needs, and the positions of supporting components such as guardrails need to be frequently adjusted according to actual conditions. However, when adjusting these components, traditional nursing devices are complicated to operate and the stability after adjustment is difficult to ensure. This not only increases the difficulty of operation for nursing staff, but may also cause patients to feel uncomfortable or create safety hazards during the adjustment process. Therefore, how to design a system that can easily, quickly and stably switch the position of the guardrail has become the key to solving the flexibility and safety problems of nursing devices. Summary of the invention

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: A posture auxiliary device for thoracic surgery nursing, comprising:

[0008] A bottom frame, with a bed board mounted on the top, an extension mechanism disposed inside the bed board, and a shock absorbing mechanism disposed at the bottom of the extension mechanism;

[0012] Preferably, a fixed plate is fixed at the bottom end of the second connecting rod, a slider 1 slides inside the third docking rod, a slide plate 1 is fixed to the bottom end of the slider 1, the slide plate 1 slides in the fixed plate, a contact plate 1 is provided at the bottom of the fixed plate, and a contact plate 2 is provided at the bottom of the slide plate 1.

[0013] Preferably, a limiting column is arranged between the fixed plate and the contact plate 1, another limiting column is arranged between the slide plate 1 and the contact plate 2, and the outer wall of each limiting column is sleeved with a spring 1, one end of the spring 1 is fixed to the top of the contact plate 1, and the other end of the spring 1 is fixed to the bottom of the fixed plate.

[0014] Preferably, the shock absorbing mechanism comprises a connecting plate, the connecting plate is fixed inside the bed board, a pressure block is fixed on one side of the connecting plate, a limiting position frame is arranged between the pressure blocks, and an air cushion is arranged between the pressure blocks.

[0015] Preferably, the limiting frame 1 is fixed with the limiting frame 2 on both sides, the connecting plate has a connecting rod 3 rotatably provided on one side, and the sliding block 2 is rotatably provided between the connecting rods 3 via a connecting shaft.

[0016] Preferably, the second sliding block slides inside the second limiting frame, a damper is provided on one side of the second limiting frame, and an output end of the damper is fixed inside the second limiting frame.

[0017] Preferably, a connecting hole is provided inside the extension plate, and the extension plate is connected to a guardrail through the connecting hole.

[0018] Preferably, a second spring is provided inside the guardrail, one end of the second spring is fixed inside the guardrail, and a docking block is fixed to the other end of the second spring, and a ball bearing is provided on one side of the docking block.

[0019] Preferably, a magnet 1 is fixed to the outer wall of the docking block, a limiting rod 2 is slidably arranged inside the magnet 1, a magnet 2 is fixed to the middle of the limiting rod 2, the magnet 2 repels the magnet 1, and the limiting rod 2 is fixed in the guardrail.

[0020] Working principle: When it is necessary to expand the use area, the motor can be used to drive gear one to rotate, thereby driving gear two and the two-way threaded column to rotate in the opposite direction, so that the threads of the two-way threaded column can make the extension plates on both sides follow the threads to expand outward and retract inward under the restriction of limit rod one. When the extension plate extends to both sides, the corresponding connecting rod one will move synchronously, thereby driving the inclination angle of docking rod one to change. Because the appearance of connecting rod two is fixed, the direction of the change of the inclination angle of corresponding docking rod one is fixed, and then the inclination angle of docking rod two can be pushed to change with the sliding of connecting rod two, and then Shudie docking rod three is pushed by the docking rod two with the changed angle, and then by pulling The movable slide plate 1 and the contact plate 2 are displaced, and when the connecting rod 2 is displaced downward to push the fixed plate and the contact plate 1 together, the corresponding slide plate 1 and the contact plate 2 can be changed together under the action of the slider 1, so as to expand and open the contact plate 2 synchronously on both sides, thereby stabilizing the equipment after the extended plate is used, and the base frame as a whole can move accordingly. When the base frame encounters vibration during movement, the corresponding vibration force will first be transmitted to the pressure block through the connecting plate, so that the air cushion between the two pressure blocks is slightly squeezed, thereby realizing the first gas buffering. When the position between the pressure blocks changes slightly, the inclination angle of the connecting rod 3 will change, and then the slider 2 will be pushed through the rotating shaft. The damper is used to exert force, thereby performing a second buffering of the vibration force. After the extension plate is expanded and used, when the patient's own thoracic surgery needs to turn sideways, the guardrail can be pulled to disengage it from the connecting hole, and then inserted into a new connecting hole to freely adjust its position. When the guardrail is separated from the connecting hole, the corresponding ball will first be squeezed by force, and then pressure will be applied to spring two through the docking block. At the same time, magnet one will also move closer to magnet two due to the restriction of limit rod two. At this time, the guardrail is successfully detached. The same is true during installation. The ball will still be squeezed first. However, after the ball is aligned with the reserved hole in the corresponding connecting hole, the corresponding spring two will push the docking block to drive the ball to engage with the corresponding hole through the elastic potential energy generated by its own reduction. At the same time, magnet two will further push the docking block to achieve the engagement of the ball through the repulsive force between it and magnet one.

[0021] The present invention provides a posture assisting device for thoracic surgery nursing, which has the following beneficial effects:

[0022] 1. The present invention uses a support mechanism to ensure that both sides are simultaneously unfolded and firmly support the use surface of the equipment when the extension plate is extended and expanded. This synchronous support capability effectively enhances the overall stability of the equipment, prevents structural tilt or instability caused by uneven expansion, thereby ensuring the safety and durability of the equipment.

[0023] 2. The present invention effectively absorbs and reduces the impact of vibration on the equipment through a multi-level buffer system. This shock absorption capability ensures the smooth operation of the equipment in various unstable environments, significantly improves the comfort of patients, and also prolongs the service life of the equipment.

[0024] 3. The present invention allows nursing staff to freely adjust the position of the guardrail according to the needs of the patient, and the adjustment process is simple and quick. The ability to switch positions at will provides great convenience for nursing operations, while also ensuring the stability of the guardrail in different positions, providing patients with flexible and safe nursing support.

[0033] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Please see attached Figure 1 , Attachment Figure 2 and attached Figure 4 The embodiment of the present invention provides a posture assisting device for thoracic surgery nursing, comprising:

[0035] A bottom frame 1, a bed board 2 is mounted on the top thereof, an extension mechanism 3 is arranged inside the bed board 2, and a shock absorbing mechanism 5 is arranged at the bottom of the extension mechanism 3;

[0036] Support mechanism 4, which is installed on both sides of the base frame 1, and is used to adapt to the expansion of the equipment;

[0037] The extension mechanism 3 includes an extension plate 11, a motor 7 is arranged between the extension plates 11, a gear 1 8 is fixed to the output end of the motor 7, a gear 2 10 is arranged on one side of the gear 1 8, a bidirectional threaded column 9 is fixed to the inner wall of the gear 2 10, the bidirectional threaded column 9 is threadedly connected in the extension plate 11, the gear 1 8 is meshed with the gear 2 10, and the extension plates 11 are limited to slide by a limit rod 1 32.

[0038] Specifically, when it is necessary to expand the usable area, the motor 7 is first activated to drive the internally connected gear 8 to start rotating clockwise or counterclockwise. The rotation of gear 18 directly meshes with gear 2 10, driving gear 2 10 to rotate synchronously in the opposite direction; the rotation of gear 2 10 is further transmitted to the connected bidirectional threaded column 9, so that the bidirectional threaded column 9 produces reverse rotation on its axis. The thread structure of the bidirectional threaded column 9 has been precisely designed to give full play to the mechanical properties of the thread during the rotation process and accurately control the movement trajectory of the extension plates 11 on both sides. During this process, the extension plates 11 are driven by the bidirectional threaded column 9 to expand or retract along the set trajectory; in order to ensure the stability and safety of the extension plate 11 during the movement, the device is equipped with a limit rod 32, whose main function is to limit the movement range of the extension plate 11 to prevent excessive movement or derailment during operation. The existence of the limit rod 32 makes the expansion and contraction process of the extension plate 11 smoother and more reliable, effectively avoiding potential risks in the operation of the device.

[0039] Please see attached Figure 3 and attached Figure 5The supporting mechanism 4 includes a connecting rod 12, which is fixed at the bottom of the extension plate 11. The bottom end of the connecting rod 12 is rotatably connected to a docking rod 13. The end of the docking rod 13 away from the connecting rod 12 is connected to a docking rod 2 14 and a connecting rod 2 16 through the same rotating shaft. The end of the docking rod 2 14 away from the docking rod 13 is rotatably connected to a docking rod 3 15. Storage frames are fixed on both sides of the bottom frame 1. The docking rod 3 15 and the connecting rod 2 16 both slide in the storage frames. The bottom end of the connecting rod 2 16 is fixed with a fixing plate 18. The docking rod 3 15 slides inside. There is a slider 17, a slider 19 is fixed to the bottom of the slider 17, the slider 19 slides in the fixed plate 18, a contact plate 20 is provided at the bottom of the fixed plate 18, a contact plate 21 is provided at the bottom of the slider 19, a limiting column 22 is provided between the fixed plate 18 and the contact plate 20, another limiting column 22 is provided between the slider 19 and the contact plate 21, the outer wall of the limiting column 22 is sleeved with a spring 23, one end of a spring 23 is fixed to the top of the contact plate 20, and the other end of a spring 23 is fixed to the bottom of the fixed plate 18.

[0040] Specifically, as the extension plate 11 expands, the corresponding connecting rod 12 will move synchronously. This movement directly drives the inclination angle of the docking rod 13 to change through precise mechanical transmission. This angle change is not random, but under the fixed guidance of the connecting rod 2 16, it ensures that the inclination direction of the docking rod 13 always remains consistent; the existence of the connecting rod 2 16 plays a crucial role. It not only limits the direction of the angle change of the docking rod 13, but also further drives the inclination angle of the docking rod 2 14 to change accordingly through its own sliding process. As the angle of the docking rod 2 14 is adjusted, the docking rod 3 15 connected to it is also forced to change its angle, thereby triggering a subsequent mechanical response; the angle change of the docking rod 3 15 directly acts on the skateboard 19 and the contact plate 2 1, so that it is displaced under the action of traction. At this time, due to the downward displacement of the connecting rod 16, the fixing plate 18, when subjected to downward pressure, moves downward synchronously with the contact plate 1 20, pushing the entire structure to be in closer contact with the ground. Under the guidance of the slider 17, the sliding plate 19 and the contact plate 21 can stably and coordinately change their positions along with the movement of the connecting rod 16. Through this complex and precise mechanical linkage, the expansion of the extension plates 11 on both sides not only realizes the expansion of space, but more importantly, through the synchronous opening of the contact plate 21, the stability of the equipment after the expansion is greatly enhanced. This design ensures that after the extension plates 11 are fully unfolded, the entire device can maintain extremely high stability and load-bearing capacity on the ground, thereby providing a reliable foundation for subsequent use.

[0041] Please see attached Figure 6The shock absorbing mechanism 5 includes a connecting plate 24, which is fixed inside the bed board 2. A pressure block 26 is fixed on one side of the connecting plate 24. A limit frame 1 27 is arranged between the pressure blocks 26. An air cushion 28 is arranged between the pressure blocks 26. A limit frame 29 is fixed on both sides of the limit frame 1 27. A connecting rod 3 25 is rotatable on one side of the connecting plate 24. A slider 2 39 is rotatable between the connecting rods 3 25 through a connecting shaft. The slider 2 39 slides inside the limit frame 29. A damper 30 is arranged on one side of the limit frame 29. The output end of the damper 30 is fixed inside the limit frame 29.

[0042] Specifically, when the chassis 1 encounters vibration during movement, the vibration force will first be transmitted through the connecting plate 24, and this vibration force will be quickly transmitted to the pressing block 26. At this time, the pressing block 26 begins to apply a slight squeezing force to the air cushion 28 located between them, causing the air cushion 28 to deform, thereby realizing the first gas buffering. This primary buffering process effectively absorbs part of the vibration force through the compression and release of the gas, reducing the direct impact on the overall structure of the chassis 1. As the vibration continues, the relative position of the pressing blocks 26 will change slightly, and this change will cause the inclination angle of the connecting rod three 25 to change. The angle adjustment of the connecting rod three 25 is achieved through The precise mechanical transmission structure further promotes the slider 2 39 connected thereto to move along the set track. The movement of the slider 2 39 thereby triggers the damper 30 to function. The damper 30, as the core shock-absorbing element, performs a second buffering of the vibration force through the action of its internal damping medium. This process significantly reduces the vibration intensity transmitted to the base frame 1, making the device more stable and safe during movement. The design of the entire seismic buffering system ensures that when the base frame 1 encounters external vibration, the transmission and impact of the vibration force are effectively weakened through the coordinated work of the multi-stage buffering structure, thereby maximizing the protection of the stability of the equipment and the integrity of the overall structure.

[0043] Please see attached Figure 7 A connecting hole 31 is opened inside the extension plate 11, and the extension plate 11 is connected to the guardrail 6 through the connecting hole 31. A spring 2 33 is arranged inside the guardrail 6. One end of the spring 2 33 is fixed inside the guardrail 6, and a docking block 34 is fixed to the other end of the spring 2 33. A ball 38 is arranged on one side of the docking block 34. A magnet 1 35 is fixed to the outer wall of the docking block 34. A limit rod 2 36 slides inside the magnet 1 35. A magnet 2 37 is fixed to the middle of the limit rod 2 36. The magnet 2 37 and the magnet 1 35 repel each other, and the limit rod 2 36 is fixed in the guardrail 6.

[0044] Specifically, after the extension plate 11 is used, in order to better meet the special needs of patients such as sideways movement in thoracic surgery care, the device is designed with a convenient guardrail 6 position control mechanism. When the position of the guardrail 6 needs to be adjusted, the nursing staff can gently pull the guardrail 6 to disengage it from the original connecting hole 31. In this process, the ball 38 will first be squeezed by an external force, forcing it to move in the channel. As the ball 38 moves, the docking block 34 moves accordingly, thereby applying pressure to the spring 2 33. While compressing the spring 2 33, the magnet 1 35 gradually moves toward the magnet 2 37 under the guidance of the limit rod 2 36. This series of actions eventually makes the guardrail 6 move smoothly. The second spring 33 can restore the original state due to its inherent elastic potential energy, thereby pushing the docking block 34 to drive the ball 38 to re-engage in place. At the same time, the second magnet 37 is further pushed by the repulsive force generated by the first magnet 35 to push the docking block 34, ensuring that the ball 38 is firmly engaged in the new hole position, thereby completing the stable installation of the guardrail 6.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
