Description

Technical Field

[0001] This application relates to the field of vibration damping devices, and in particular to a vibration damping device for medical equipment. Background Technology

[0002] Vibration damping devices for medical equipment are critical infrastructure designed to ensure the precise and stable operation of high-end medical equipment such as MRI, CT, and electron microscopes. Their design stems from the high sensitivity of these devices to their operating environment: microsecond-level vibrations from external environments (such as traffic and construction) and building activities (such as personnel movement and equipment start-up and shutdown), even with extremely small amplitudes, can lead to blurred images, distorted measurement data, or equipment calibration deviations, directly affecting the accuracy of clinical diagnosis and the reliability of research data. The core function of vibration damping devices is to actively isolate and dissipate this vibration energy. By integrating high-performance vibration isolators, inertial bases, and other composite technologies, an effective isolation barrier is constructed between the precision equipment and the vibration source, effectively filtering out broadband vibration interference.

[0003] However, existing vibration damping devices for medical equipment still have the following shortcomings: Currently, vibration damping seats are commonly used to support and isolate the equipment vertically. While this type of structure has a certain isolation effect on vertical vibrations, its ability to isolate vibrations transmitted horizontally is limited. In addition, vibration damping seats are usually placed directly on the ground. When the ground is uneven, it can easily lead to the overall imbalance of the vibration damping seat, thereby affecting its stability and balance in supporting the medical equipment. Summary of the Invention

[0004] In order to improve the limited horizontal vibration isolation effect of existing vibration damping devices and their susceptibility to uneven ground, this application provides a vibration damping device for medical equipment.

[0005] The medical equipment shock absorption device provided in this application adopts the following technical solution: A shock absorption device for medical equipment, comprising: Base; A support base, disposed on the base, is used to support the medical equipment; A vertical shock absorption mechanism is disposed between the base and the support. An inclined damping mechanism includes multiple dampers connected between the base and the support, the dampers being inclined and the multiple dampers being evenly distributed along the circumference of the support. An adsorption mechanism, disposed on the support base, is used to adsorb and fix the medical device. A balancing mechanism, mounted on the base, is used to adjust the levelness of the base.

[0006] This application constructs a multi-dimensional vibration isolation system by integrating a vertical damping mechanism and an oblique damping mechanism: the vertical damping mechanism effectively isolates vertical vibrations, and multiple oblique dampers evenly distributed along the circumference can decompose the generated damping force into horizontal and vertical components, improving the limited vibration isolation effect of existing technologies and enhancing the horizontal vibration isolation effect; at the same time, the adsorption mechanism ensures that the medical equipment is firmly connected to the support base, reducing relative slippage of the equipment during vibration reduction; the balancing mechanism can adapt to uneven ground, ensuring that the base is always in a horizontal state, providing a stable and balanced working platform for the equipment.

[0007] Furthermore, the balancing mechanism includes multiple extended legs fixed to the perimeter of the base. The lower end face of each extended leg has a receiving groove. An airbag and an adjusting block fixed to the airbag are disposed in the receiving groove. The airbag is connected to an external air source, and the lower end face of the adjusting block abuts against the ground.

[0008] Multiple airbags are used to adjust the height of each extension leg. When placed on uneven ground, the lower end of the adjustment block is in close contact with the ground. By adjusting the inflation of each airbag through an external air source, the corresponding extension leg is lifted to a suitable height, ensuring that the base is in an ideal horizontal state. This improves the problem of uneven ground affecting the overall balance of the shock absorption device.

[0009] Furthermore, the damper is hinged to two ends, with hinge seat one and hinge seat two respectively. Hinge seat one is fixed to the extension leg, and hinge seat two is detachably connected to the support base.

[0010] Furthermore, a plug plate is fixedly connected to one side of the hinge seat 2, and a plug groove for inserting the plug plate is opened on the side of the support seat. A positioning groove communicating with the plug groove is opened on the upper end face of the support seat. A positioning element is provided in the positioning groove. The positioning element includes a positioning plate and a plug post fixed to the positioning plate. The positioning plate is engaged with the positioning groove. A plug hole for inserting the plug post is opened on the plug plate.

[0011] The damper and the support base are detachably connected, which facilitates on-site assembly and subsequent maintenance or replacement of individual dampers. During installation, simply insert the plug plate of the hinge base into the plug slot of the support base, and then insert the positioning piece into the positioning slot from above, so that the plug pin is inserted into the plug hole of the plug plate to complete the locking; the whole process does not require the use of tools, realizing quick assembly and disassembly.

[0012] Furthermore, the adsorption mechanism includes multiple extended rotating plates that are elastically hinged around the support base, and multiple suction cups are provided on the extended rotating plates for adsorbing the surface of the medical device.

[0013] Furthermore, the suction cup is fixedly connected to a support column, and the extended rotating plate has a blind hole for accommodating the support column, with an elastic element disposed in the blind hole.

[0014] Furthermore, the support base is provided with a storage groove around its perimeter for accommodating the extended rotating plate, and the support base is provided with a limiting component for confining the extended rotating plate within the storage groove.

[0015] With the flexible hinged extension plate, when the extension plate rotates out of the storage slot, the support column and suction cup can bounce upward under the action of the elastic element, so that the suction cup is tightly attached to the bottom of the medical device, improving the stability of the medical device fixation.

[0016] When the adsorption mechanism is not needed or the shock-absorbing device needs to be moved or stored, the extension plate can be rotated and stored in the storage slots around the support base and fixed by the limiting components, making the overall structure of the device compact; the stored state also protects the extension plate and suction cup from accidental collisions when not in operation.

[0017] Furthermore, the vertical damping mechanism includes a damper disposed at the center of the base, and a plurality of positioning sleeves disposed around the damper. The positioning sleeves are elastically connected to telescopic columns, and the upper surfaces of the damper and the telescopic columns abut against the support base.

[0018] The central shock absorber and multiple elastic telescopic columns around it form a structure with the central main load bearing and the surrounding auxiliary support and guidance. The central shock absorber is responsible for bearing the main vertical load and isolating vibration. The telescopic columns around it move vertically under the guidance of the positioning sleeve, which not only enhances the stability of the support seat, but also helps to dissipate vibration energy through their own elastic elements. This multi-point support structure makes the force more uniform and improves the support stiffness of precision medical equipment.

[0019] Furthermore, the lower end face of the support base is provided with a large collar and a small collar, the large collar being used to accommodate the end of the shock absorber, and the small collar being used to accommodate the end of the telescopic column.

[0020] By setting a large collar and a small collar on the lower end face of the support base, which correspond to the ends of the shock absorber and the telescopic column respectively, the support base and the vertical shock absorption mechanism are precisely aligned and quickly installed. The collar structure not only plays a positioning and guiding role, ensuring that the shock absorber and the telescopic column are always subjected to vertical force, but also limits the end of the shock absorber in the horizontal direction to prevent lateral displacement, further improving the stability of the device in the horizontal direction.

[0021] Furthermore, multiple fixing tubes are fixed to the outer periphery of the large collar, and a pin is slidably disposed in the fixing tube. One end of the pin passes radially through the large collar and abuts against the shock absorber, and a pull plate is fixed to the other end of the pin. The pull plate abuts against the end of the fixing tube. An elastic element is disposed in the fixing tube to drive the pin to move toward the center of the large collar.

[0022] Under normal operating conditions, the elastic element drives the pin to press against the side of the shock absorber, maintaining a stable connection between the support and the shock absorber. When maintenance is required, simply pull the pull plate outward to move the pin outward, separating the pin from the upper end of the shock absorber, thus separating the support from the shock absorber.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. This application decomposes the generated damping force into horizontal and vertical components by using multiple tilting dampers, which improves the problem of limited vibration isolation effect in the horizontal direction in the prior art and enhances the horizontal vibration isolation effect; 2. Multiple airbags are used to adjust the height of each extension leg. When placed on uneven ground, the inflation of each airbag can be adjusted by an external air source to ensure that the lower end of all adjustment blocks is in close contact with the ground, while ensuring that the base is in an ideal level state. This improves the problem that uneven ground affects the overall balance of the shock absorption device. 3. With the flexible hinged extension plate, when the extension plate rotates out of the storage slot, the support column and suction cup can spring upward under the action of the elastic element, so that the suction cup is tightly attached to the bottom of the medical device, improving the stability of the medical device. When the suction mechanism is not needed or the shock absorption device needs to be moved or stored, the extension plate can be rotated and stored in the storage slot around the support base, and fixed by the limiting component, making the overall structure of the device compact. The stored state also protects the extension plate and suction cup from accidental collisions when not in use. 4. By setting up a large collar and a quick disassembly and assembly structure, when the shock absorber needs to be repaired, simply pull the pull plate outward to move the pin outward, so that the pin separates from the upper end of the shock absorber, and the support seat can be separated from the shock absorber.

[0026] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0027] This application discloses a shock absorption device for medical equipment. (Refer to...) Figure 1 The medical equipment shock absorption device includes a base 18, a support 1, a vertical shock absorption mechanism, an oblique damping mechanism, an adsorption mechanism, and a balancing mechanism 19.

[0028] Reference Figure 1 The base 18 is placed on the ground, and the balancing mechanism 19 is mounted on the base 18 to adjust its level, providing a stable and balanced working platform for the medical device. The support base 1 is mounted on the base 18 to support the medical device. To improve the stability of the load-bearing structure, the upper surface of the support base 1 is provided with several friction strips 9, which can be made of rubber, to increase the friction between the support base 1 and the medical device. An adsorption mechanism is mounted on the support base 1 to adsorb and fix the medical device, further improving the stability of the medical device's placement. In this embodiment, both the base 18 and the support base 1 are square.

[0029] Reference Figure 2A vertical damping mechanism is installed between the base 18 and the support 1 to isolate vertical vibrations. The vertical damping mechanism includes a damper 22 located at the center of the base 18 and four positioning sleeves 20 located around the damper 22. The positioning sleeves 20 are elastically connected to telescopic columns 21. Specifically, springs are installed inside the positioning sleeves 20 to elastically support the telescopic columns 21.

[0030] Reference Figure 2 and Figure 3 The upper surfaces of the shock absorber 22 and the telescopic column 21 are both abutted against the bottom of the support base 1; the lower surface of the support base 1 is provided with a large collar 24 and a small collar 23. The large collar 24 is used to accommodate the end of the shock absorber 22, and the small collar 23 is used to accommodate the end of the telescopic column 21, so as to achieve precise alignment and quick installation of the support base 1 and the vertical shock absorption mechanism.

[0031] To achieve the connection between support 1 and the vertical damping mechanism, refer to Figure 4 Four fixing tubes 241 are fixed to the outer circumference of the large collar 24. A pin 242 is slidably disposed within each fixing tube 241. One end of the pin 242 radially passes through the large collar 24 and abuts against the shock absorber 22. The other end of the pin 242 is fixed to a pull plate 244, which abuts against the end of the fixing tube 241. To guide the movement of the pin 242, a limit ring 243 is fixedly disposed within the fixing tube 241, and the pin 242 slidably passes through the limit ring 243. An elastic element, a spring, is disposed within the fixing tube 241. One end of the spring is fixed to the pull plate 244, and the other end is fixed to the limit ring 243. The tension of the spring drives the pin 242 to move towards the center of the large collar 24.

[0032] Under normal operating conditions, the elastic element drives the pin 242 to press against the side of the shock absorber 22, keeping the support base 1 and the shock absorber 22 stably connected. When the shock absorber 22 needs maintenance, simply pull the pull plate 244 outward to move the pin 242 outward, separating the pin 242 from the upper end of the shock absorber 22, thus separating the support base 1 from the shock absorber 22.

[0033] Reference Figure 1 and Figure 5 The balancing mechanism 19 includes four extended legs 191 fixed around the base 18. The lower end face of the extended legs 191 is provided with a receiving groove, in which an airbag 194 and an adjusting block 195 fixed to the airbag 194 are arranged. The lower end face of the adjusting block 195 abuts against the ground. The airbag 194 is a multi-layered rubber airbag 194, which is connected to an interface 192 on the extended legs 191 through an air guide tube 193. The interface 192 is connected to an external air compressor.

[0034] Multiple airbags 194 are used to adjust the height of each extension leg 191. When placed on uneven ground, the lower end of the adjusting block 195 is in close contact with the ground. By adjusting the inflation of each airbag 194 through an external air source, the corresponding extension leg 191 is lifted to a suitable height, ensuring that the base 18 is in an ideal horizontal state. This improves the problem that uneven ground affects the overall balance of the shock absorption device.

[0035] Reference Figure 1 and Figure 6 The inclined damping mechanism includes four dampers 10 connected between the base 18 and the support 1. The dampers 10 are inclined and evenly distributed along the circumference of the support 1. The inclined dampers 10 can decompose the generated damping force into horizontal and vertical components, which improves the problem of limited vibration isolation effect in the horizontal direction in the prior art and enhances the horizontal vibration isolation effect.

[0036] Reference Figure 1 , Figure 6 and Figure 7 The damper 10 has a hinge seat 11 and a hinge seat 12 hinged to its two ends respectively. The hinge seat 11 is fixed to the extension leg 191, and the hinge seat 12 is detachably connected to the support seat 1.

[0037] Reference Figure 6 , Figure 7 and Figure 8 A connector plate 13 is fixedly connected to one side of the hinge base 12. A connector groove 17 for inserting the connector plate 13 is provided on the side of the support base 1. A positioning groove 16 communicating with the connector groove 17 is provided on the upper end face of the support base 1. A positioning element is provided in the positioning groove 16, including a positioning plate 14 and a connector post 15 fixed to the positioning plate 14. The positioning plate 14 engages with the positioning groove 16. A insertion hole for inserting the connector post 15 is provided on the connector plate 13. To facilitate removal of the positioning element from the positioning groove 16, arc-shaped grooves are provided at both ends of the positioning groove 16.

[0038] The damper 10 and the support base 1 are detachably connected, which facilitates on-site assembly and subsequent maintenance or replacement of individual dampers 10. During installation, simply insert the plug plate 13 of the hinge base 12 into the plug slot 17 of the support base 1, and then insert the positioning member into the positioning slot 16 from above, so that the plug post 15 is inserted into the plug hole of the plug plate 13 to complete the locking; the whole process does not require tools and achieves quick assembly and disassembly.

[0039] Reference Figure 7 and Figure 9The adsorption mechanism includes multiple extended rotating plates 2 elastically hinged to the support base 1 via a torsion shaft 3. The support base 1 has storage slots around its perimeter for accommodating the extended rotating plates 2. In this embodiment, two extended rotating plates 2 are provided on each side of the support base 1. Multiple suction cups 6 are provided on the extended rotating plates 2 for adsorbing the surface of the medical device.

[0040] Specifically, refer to Figure 9 A support column 5 is fixedly connected to the bottom of the suction cup 6. A blind hole for accommodating the support column 5 is provided on the extension rotating plate 2, and an elastic element is installed in the blind hole. In this embodiment, the elastic element is a telescopic flexible hose 4; in other embodiments, the elastic element can also be a spring. When the extension rotating plate 2 rotates out of the receiving groove, the support column 5 and the suction cup 6 can spring upwards under the action of the elastic element, allowing the suction cup 6 to firmly adhere to the bottom of the medical device, improving the stability of the medical device's fixation.

[0041] Furthermore, the support base 1 is provided with a limiting component for confining the extended rotating plate 2 within the storage slot; specifically, refer to... Figure 7 The limiting components include a spring guide rod 8 and a limiting stop bar 7. The spring guide rod 8 includes a guide rod fixed to the bottom surface of the support base 1 and a spring sleeved on the guide rod. The limiting stop bar 7 is L-shaped, with one end slidably sleeved on the guide rod and abutting against the spring, and the other end slidably disposed on the side of the support base 1.

[0042] When the adsorption mechanism is not needed or the shock-absorbing device needs to be moved or stored, the extension plate 2 can be rotated and stored in the storage groove around the support base 1. At this time, the limiting strip 7 abuts against one side of the extension plate 2, limiting the extension plate 2 in the storage groove. When the adsorption mechanism is needed, the limiting strip 7 is driven downward by external force to release its limitation on the extension plate 2. Under the elastic force of the torsion shaft 3, the extension plate 2 pops out of the storage groove, and the suction cup 6 pops up to adsorb and fix the bottom of the medical device.

[0043] The method of using a shock-absorbing device for medical equipment according to an embodiment of this application is as follows: the support base 1 is connected to the shock absorber 22 and the telescopic column 21 on the base 18, and the support base 1 and the shock absorber 22 are stably connected by the pin 242 on the large collar 24 to complete the installation of the support base 1; the plug plate 13 of the hinge seat 2 12 is inserted into the plug groove 17 of the support base 1, and then the positioning member is embedded into the positioning groove 16 from above, so that the plug post 15 is inserted into the plug hole of the plug plate 13, thereby installing the damper 10 obliquely between the support base 1 and the base 18. The medical device is placed on the support base 1. Vertical vibration isolation is achieved through the shock absorber 22 and the telescopic column 21. The damping force generated is decomposed into horizontal and vertical components by the inclined damper 10, improving the horizontal vibration isolation effect. The limit bar 7 is pulled down to release its restriction on the extension plate 2. The extension plate 2 pops out of the storage slot under the elastic force of the torsion shaft 3, and the suction cup 6 pops up to adsorb and fix the bottom of the medical device. After the medical device is fixed on the support base 1, the inflation of each air bag 194 is adjusted by the external air source to lift the corresponding extension leg 191 to a suitable height, ensuring that the base 18 is in an ideal horizontal state.

[0044] When maintenance is required on the damper 10 and shock absorber 22, first separate the suction cup 6 from the bottom of the medical device, then remove the medical device from the support base 1. Rotate the extension plate 2 into the support base 1 and use the limiting stop 7 to block and limit the extension plate 2. Then remove the positioning part from the positioning groove 16, and then remove the plug plate 13 from the plug groove 17. At this time, the damper 10 is separated from the support base 1, which facilitates maintenance of the damper 10. Pull the pull plate 244 outward to move the pin 242 outward, so that the pin 242 is separated from the upper end of the shock absorber 22, thus separating the support base 1 from the shock absorber 22, which facilitates maintenance of the shock absorber 22.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
