Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a protective box. Background Technology

[0002] Existing protective cases can be used to store medical equipment for transportation, reducing damage during transport. However, in some situations, medical equipment is easily damaged inside protective cases, affecting transportation. Summary of the Invention

[0003] This application provides a protective case designed to improve the problem of easy damage to medical equipment inside the case.

[0004] To achieve the above-mentioned technical effects, one technical solution adopted in this application is: to provide a protective box for placing medical equipment, the protective box comprising:

[0005] The enclosure includes a bottom wall, a top wall, and a side wall located between the bottom wall and the top wall. The side wall includes a door and multiple side panels. The top wall and the bottom wall are respectively connected to the side panels. The door is located between the top wall and the bottom wall and is movably connected to the side panels. The top wall, the bottom wall, the door, and the multiple side panels enclose and form an accommodating cavity.

[0006] A fixing component is provided in the accommodating cavity. The fixing component is provided at one end of the side plate near the bottom wall. The distance between the fixing component on the side plate and the bottom wall is not less than the height of the roller of the medical device.

[0007] The fixing components include:

[0008] The fixed base is connected to the side plate via a connector; and

[0009] A buffer element is connected to a fixed base, and the buffer element protrudes at least partially from the side of the fixed base facing the receiving cavity.

[0010] The fixed base has a groove and an opening that connects to the groove. The buffer part is embedded in the groove and partially protrudes out of the opening.

[0011] The fixed base has a connecting wall that is positioned opposite the opening, and the connecting wall is connected to the side plate via a connector.

[0012] The fixed base is made of wood, steel plate or alloy material, and / or the buffer is made of ethylene-vinyl acetate copolymer or polyurethane or polyethylene foam.

[0013] The device includes multiple fixing components. Fixing components are installed on the side panels on both sides of the door. The fixing components are positioned corresponding to the base of the medical device and are used to fit into the base of the medical device.

[0014] The number of fixing components is multiple, with at least two fixing components spaced apart along the height direction of the side plate.

[0015] The enclosure also includes a protective padding layer, which is located in the accommodating cavity. At least one of the top wall, bottom wall, and side wall is provided with a protective padding layer.

[0016] The cabinet also includes a ramp plate that is movably connected to the bottom wall or side panel between the storage position and the open position. When the ramp plate is in the storage position, it is located inside the accommodating cavity. When the ramp plate is in the open position, it is set on the same side as the cabinet door. One end of the ramp plate is connected to the bottom wall or side panel, and the other end is located on the outside of the cabinet and extends towards the bottom wall away from the top wall.

[0017] The ramp plate is hinged to the bottom wall or side plate. When the ramp plate is in the storage position, it is set at an angle to the bottom wall.

[0018] The enclosure also includes a first limiting member and a second limiting member. The first limiting member is connected to the ramp plate, and the second limiting member is connected to the side plate and extends outward from the side plate. The second limiting member is used to connect to the first limiting member when the ramp plate is in the retracted position to restrict the ramp plate from moving to the open position.

[0019] The above solution, by setting fixed components inside the enclosure, can, on the one hand, guide the medical equipment during its insertion or removal, thereby reducing collisions between the medical equipment and the enclosure; on the other hand, by restricting the position of the medical equipment inside the enclosure, it can reduce the shaking of the medical equipment relative to the enclosure, thus reducing wear and tear; furthermore, by positioning the medical equipment within the enclosure, it can reduce the eccentricity of the medical equipment relative to the enclosure, thus helping to improve the stability of the enclosure.

Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0041] Protective cases for medical equipment are typically rectangular in shape, with an internal cavity creating a hollow structure. The medical equipment can be placed inside this cavity, reducing the risk of impact and damage during transport. These cases are usually made of hollow wooden boards and are equipped with casters at the bottom for easy movement.

[0042] Please see Figures 1 to 7 This application proposes an example of a protective case for placing medical equipment. The protective case includes a case body 10 and a fixing component 40. The case body 10 includes a bottom wall 11, a top wall 13, and a side wall 12 disposed between the bottom wall 11 and the top wall 13. The side wall 12 includes a door 122 and a plurality of side panels 121. The top wall 13 and the bottom wall 11 are respectively connected to the side panels 121. The door 122 is disposed between the top wall 13 and the bottom wall 11 and is movably connected to the side panels 121. The top wall 13, the bottom wall 11, the door 122, and the plurality of side panels 121 enclose a receiving cavity 15. The fixing component 40 is disposed in the receiving cavity 15. The fixing component 40 is provided at one end of the side panel 121 near the bottom wall 11. The distance between the fixing component 40 on the side panel 121 and the bottom wall 11 is not less than the height of the rollers of the medical equipment.

[0043] Please refer to the following: Figure 4 , Figure 5 and Figure 6The enclosure 10 serves as the main structure of the protective enclosure. At least partially, the enclosure 10 is hollow, forming a cavity 15 within it. In this example, the cavity 15 is used to house medical equipment, and its volume is larger than that of the medical equipment. The enclosure 10 includes a top wall 13, a bottom wall 11, and side walls 12 disposed between the top wall 13 and the bottom wall 11. In this example, the top wall 13 and the bottom wall 11 can be positioned opposite each other. The bottom wall 11 and the top wall 13 are respectively connected to the side walls 12, so that the top wall 13, the bottom wall 11, and the side walls 12 enclose the cavity 15. To improve space utilization, the enclosure 10 is generally a cuboid structure. In this example, there can be multiple side walls 12, so that the top wall 13, the bottom wall 11, and the multiple side walls 12 enclose the cuboid-shaped cavity 15. The housing 10 has an opening, through which medical devices can be placed into the housing 10. In this example, the opening of the housing 10 can be provided on the top wall 13, bottom wall 11 or side wall 12 of the housing 10 to facilitate the placement of medical devices into the housing 10.

[0044] Multiple side panels 121 can be enclosed to form a generally rectangular frame structure. This frame structure has an opening, which serves as an opening for the housing 10 to input and output medical equipment. A door 122 is used to close the opening. In this example, the door 122 can be connected to the side panel 121 via a hinge 18. Optionally, the door 122 can also be slidably connected to the side panel 121. In this example, the door 122 can be part of the side wall 12. By forming an opening on the side of the housing 10, it facilitates the input and output of medical equipment from the side, reducing the difficulty of inputting and outputting medical equipment and improving the convenience of transporting medical equipment.

[0045] Please see Figure 7 The fixing component 40 is located in the receiving cavity 15, meaning that the fixing component 40 is located inside the receiving cavity 15. The fixing component 40 is used to limit the movement of the medical device within the housing 10. The limiting includes restricting the movement of the medical device within the housing 10 in at least one of the directions of height, length, or width of the housing 10.

[0046] Please refer to the following: Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 In this example, the position of the fixing component 40 can correspond to the shape of the medical device. Optionally, there can be multiple fixing components 40. Optionally, adjacent fixing components 40 can be separately arranged or connected to each other. In this example, multiple fixing components 40 can be arranged along the height direction of the housing 10, or multiple fixing components 40 can be arranged along the width or length direction of the housing 10.

[0047] In this example, by setting a fixing component 40, when the medical device fixing component 40 is moved into or out of the housing 10, the fixing component 40 can be used to limit the movement trajectory of the medical device, so that the medical device can move along a preset trajectory, thereby improving the directionality of the medical device's movement. On the one hand, this can reduce wear and collisions caused by the shaking of the medical device, and on the other hand, it can reduce the problem of the medical device getting stuck between the medical device and the housing 10. After the medical device is placed in the receiving cavity 15 of the housing 10, the fixing component 40 can be used to block the movement between the side plate 121 and the medical device. The fixing component 40 can prevent the medical device from moving relative to the housing 10, keeping the medical device in a preset position within the receiving cavity 15, so that the center of gravity of the medical device can remain stable. On the one hand, this can reduce the problem of the protective box tipping over due to the relative movement of the medical device within the housing 10, and on the other hand, it can reduce the instability during the transportation of the protective box, thereby improving the safety of the protective box transportation.

[0048] In this example, the distance between the fixing component 40 on the side panel 121 and the bottom wall 11 refers to the distance between the surface of the fixing component 40 on the side panel 121 facing the bottom wall 11 and the bottom wall 11. Since medical devices are typically equipped with casters, the direction of movement of the casters is difficult to control when moving the medical device into the housing 10, especially during the process of pushing the medical device into the housing 10, where the casters are prone to rotation and jamming. In this example, by making the fixing component 40 higher than the height of the medical device's rollers, the fixing component 40 and the medical device's rollers are misaligned in the height direction of the housing 10. This reduces mutual interference between the fixing component 40 and the medical device's rollers during movement, thereby reducing the risk of injury to the medical device. On the one hand, the fixed component 40 can guide the rollers of the medical device, eliminating the need for an additional structure on the bottom wall 11 to guide the rollers. This simplifies the structure of the bottom wall 11, saves materials, and avoids the problem of low transfer efficiency caused by misalignment between the rollers and the guide structure. On the other hand, since there is no need for an additional structure on the bottom wall 11 of the housing 10 to limit the rollers of the medical device, the problem of jamming between the rollers of the medical device and the bottom wall of the housing 10 can be reduced.

[0049] In some examples, the enclosure also includes a crash ring 30 and multiple casters 20, which are respectively connected to the enclosure 10. The casters 20 are located on the side of the bottom wall 11 away from the top wall 13. The crash ring 30 is connected to the enclosure 10 and is annular, surrounding the outer surface of the side wall 12.

[0050] Casters 20 are connected to the bottom wall 11 or the side wall 12. Casters 20 can be located at the bottom of the housing 10 for moving the housing 10 when needed. In this example, casters 20 can be connected to at least one of the bottom wall 11 and the side wall 12. Of the multiple casters 20, all casters 20 can be connected to the bottom wall 11, or some casters 20 can be connected to the bottom wall and some casters can be connected to the side wall.

[0051] The anti-collision ring 30 is connected to the housing 10, meaning that the anti-collision ring 30 is installed on the housing 10. In this example, the anti-collision ring 30 is annular and surrounds the outer surface of the side wall 12, so that the anti-collision ring 30 forms a local thickening structure on the outside of the side wall 12 of the housing 10. The anti-collision ring 30 can be used to increase the space occupied on the outside of the housing 10. In related technologies, to distribute the force on the enclosure 10 and prevent it from tilting during movement, the casters 20 at the bottom of the enclosure 10 are generally located at the edge of the enclosure 10. When the enclosure 10 and casters 20 are projected onto a horizontal plane, some casters 20 will protrude slightly from the outside of the enclosure 10. During the movement of the enclosure 10, if there are walls or other foreign objects outside the enclosure 10, especially when the protective enclosure collides with a vertical wall, the casters 20 at the bottom of the enclosure 10 will be the first to be impacted by the external force, which can easily lead to damage to the casters 20. When the casters 20 are damaged, the enclosure 10 will tilt, causing the internal medical equipment to be impacted, and may even directly render the enclosure 10 unusable. In this example, by setting an annular anti-collision ring 30 on the outside of the side wall 12 of the enclosure 10, when the enclosure 10 and casters 20 are projected onto a horizontal plane, the anti-collision ring 30 will form a blocking structure on the outside of the side wall 12 of the enclosure 10, thereby reducing the direct impact of external walls and other structures on the casters 20. Because the anti-collision ring 30 forms a ring structure on the outer side of the side wall 12, it does not cover the entire surface of the side wall 12 of the box 10, thus having a relatively lower impact on the overall weight of the box 10. In this example, the anti-collision ring 30 surrounds the side wall 12 on the outer surface of the box 10, increasing the connection area between the anti-collision ring 30 and the side wall 12. This makes it less likely for the anti-collision ring 30 to fall off. On the one hand, this reduces the problem of damage to the casters 20 caused by the anti-collision ring 30 falling off during transportation. On the other hand, during the transportation of multiple boxes 10, the gaps between the boxes 10 are relatively fixed. By increasing the connection area between the anti-collision ring 30 and the box 10, the problem of sudden changes in the distance between adjacent boxes 10 caused by the anti-collision ring 30 falling off can be reduced, thereby reducing displacement and collisions during the transportation of the protective boxes. Furthermore, when adjacent protective boxes are arranged irregularly, collisions between adjacent protective boxes 10 are less likely, thus reducing mutual damage between adjacent protective boxes. In this example, the installation position of the anti-collision ring 30 can be determined according to the height of the box 10. The number of anti-collision rings 30 can be one or more.

[0052] In this example, the top wall 13, bottom wall 11, and side wall 12 of the housing 10 can be made of wood or other boards. Taking wood as an example, the wood boards of the bottom wall 11, top wall 13, and side wall 12 can be connected and fixed to each other by edge strips 16. The edge strips 16 can be metal strip structures, and the corresponding wood boards can be connected and fixed to the edge strips 16 by rivets or other structures. To facilitate the movement of the housing 10, handles 17 can also be provided on the housing 10. In some examples, in order to reduce the damage of the housing 10 to the medical equipment, a protective padding layer 14 is provided on the surface of at least one of the top wall 13, bottom wall 11, and side wall 12 facing the accommodating cavity 15. The protective padding layer 14 can be at least one of EVA (ethylene-vinyl acetate copolymer), PU (polyurethane) sponge, and EPE (expanded polyethylene foam), or other materials that can provide cushioning and protection. The protective padding layer 14 can be multiple layers, and the materials of the multiple protective padding layers 14 can be the same or different. In this application example, the protective padding layer 14 in different locations can be made of the same or different materials. In some examples, a protective padding layer 14 is provided on the top wall 13. The protective padding layer 14 on the top wall 13 can be a sheet structure or composite layer structure formed of at least one material selected from EVA, PU foam, and EPE. The protective padding layer 14 on the top wall 13 can be used to protect and dampen components such as the display of the medical device, and can also be used to protect the top surface of the medical device. In some examples, a protective padding layer 14 is provided on the bottom wall 11. The protective padding layer 14 on the bottom wall 11 can be made of EVA material, and the EVA material can be high-density EVA material. In this example, when the medical device is placed inside the housing 10, the protective padding layer 14 on the bottom wall 11 can be used to cushion the lower end of the medical device, improve the shock absorption performance of the bottom wall 11, and reduce the possibility of deformation of the bottom wall 11.In some examples, a protective padding layer 14 is provided on the side wall 12. The protective padding layer 14 on the side wall 12 can be a sheet structure or a composite layer structure made of EVA or EPE material. In this example, there can be multiple side walls 12, which are respectively connected between the top wall 13 and the bottom wall 11. The materials of the multiple side walls 12 can be the same or different. Optionally, one of the side walls 12 of the housing 10 can form a door 122. The door 122 can be used to close the accommodating cavity 15, and the user can move the medical device in or out from the door 122. A protective padding layer 14 can be provided on the door 122. In this example, the thickness of the protective padding layer 14 on the door 122 can be 10-20 mm. In some examples, the thickness of the protective padding layer 14 on the door 122 can be 15 mm. Optionally, the thickness of the side wall 12 opposite to the door 122 can be close to or the same as the thickness of the door 122.

[0053] In some examples, in the projection of the bumper ring 30 and multiple casters 20 onto the horizontal plane, the multiple casters 20 are located inside the bumper ring 30.

[0054] In this example, the horizontal plane is used as a reference plane, and the anti-collision ring 30 and multiple casters 20 are projected onto the horizontal plane. Within the projection plane, the multiple casters 20 are located within the outer contour of the anti-collision ring 30. The housing 10 has a height direction, and the multiple casters 20 are located below the housing 10. Since the anti-collision ring 30 can increase the space occupied by the exterior of the housing 10, when the protective housing collides with the wall, the anti-collision ring 30 forms a partition between the outer surface of the housing 10 and the wall, thereby reducing the direct collision between the wall and the casters 20 and thus reducing the possibility of damage to the casters 20. During the transportation of the protective case, due to the high structural strength of the case body 10, the connection between the casters 20 and the case body 10 is usually relatively weak when the case body 10 collides with a wall. This is especially true when transporting large medical equipment, which is heavy and therefore highly susceptible to damage to the casters 20. In this example, a crash ring 30 is installed on the case body 10 to form a protective area above the casters 20, protecting them without affecting their installation and use. In this example, the crash ring 30 and multiple casters 20 are projected onto a horizontal plane. Within this projection, the thickness of the crash ring 30 corresponds to the weight of the medical equipment to be stored inside the protective case; the thickness of the crash ring 30 is positively correlated with the weight of the medical equipment. In some examples, the rated load of the protective case is positively correlated with the weight of the medical equipment; therefore, the thickness of the crash ring 30 is also positively correlated with the rated load of the protective case.

[0055] In some examples, the caster 20 includes a movable caster 21, which includes a rotating assembly 211 and a roller 212. The rotating assembly 211 is rotatably connected to the bottom wall 11 or the side wall 12, and the roller 212 is connected to the rotating assembly 211. The rotating assembly 211 can serve as an intermediate connector between the housing 10 and the roller 212, allowing the direction of movement of the housing 10 to be changed by adjusting the direction of the roller 212. In this example, a caster fixing plate 113 can be provided on the bottom wall 11 of the housing 10. The caster fixing plate 113 can be a plate on the side of the bottom wall 11 facing away from the top wall 13. The caster fixing plate 113 can be integrally formed with the bottom wall 11, or it can be separately formed from the bottom wall 11 and connected to each other. The caster fixing plate 113 can be used to increase the installation space on the side of the bottom wall 11 facing away from the top wall 13, thereby improving the reliability of the caster 20. The caster 20 in this example may also include a directional caster 22, which may be a caster 20 that can only move in one fixed direction.

[0056] In some examples, in the projection of the anti-collision ring 30 and the roller 212 onto the horizontal plane, the outermost edge of the maximum rotation of the roller 212 is located inside the anti-collision ring 30. When the housing 10, the roller 212, and the rotating assembly 211 are projected onto the horizontal plane, the outermost edge of the maximum rotation of the roller 212 refers to the maximum distance between the outer edge of the roller 212 and the axis of the rotating assembly 211 when the rotating assembly 211 rotates. Since the axis of the roller 212 may be spaced apart from the axis of the rotating assembly 211, the outermost edge of the maximum rotation of the roller 212's rotation trajectory may extend beyond the outer side of the housing 10. In this example, in the projection plane, the outermost edge of the maximum rotation of the roller 212 is located inside the anti-collision ring 30, so that the roller 212 is within the protection range of the anti-collision ring 30, reducing the problem of protection failure caused by the relative movement of the movable caster 21 when the protective housing is moved.

[0057] In some examples, there are multiple movable casters 21, with at least two movable casters 21 located on the same side of the housing 10. In this example, by setting multiple movable casters 21, the direction of movement of the housing 10 can be easily controlled; "at least two movable casters 21 located on the same side of the housing 10" means that at least two movable casters 21 are located on the same side in the length or width direction below the housing 10.

[0058] In some examples, the side wall 12 of the box 10 may include a front wall and a rear wall. During the movement of the box 10, the operator can push the box 10 from the front wall side. When the box 10 has the aforementioned door 122, the door 122 can be the front wall of the box 10, and the side wall 12 opposite to the door 122 can be the rear wall. A movable caster 21 is provided on the side near the front wall of the box 10, and a directional caster 22 is provided on the side near the rear wall of the box 10. During the movement of the box 10, the directional caster 22 of the box 10 can rotate in a direction so that the rear wall side of the box 10 can maintain a stable direction of movement, reducing the degree of freedom of the caster 20 on the rear wall side of the box 10, thereby reducing the possibility of shaking during the movement of the box 10. The operator can control the direction of the movable caster 21 on the front wall side of the box 10 to control the direction of movement of the box 10. In this example, the number of directional casters 22 on the rear wall side of the housing 10 can be one or more. Taking two directional casters 22 on the rear wall side of the housing 10 as an example, the two directional casters 22 can be respectively located near the top corner of the edge of the housing 10. In this example, the number of movable casters 21 on the front wall side of the housing 10 can be one or more. When multiple movable casters 21 are provided, movable casters 21 can be respectively located near the top corner of the edge of the front wall of the housing 10. Optionally, the housing 10 has the aforementioned door 122, and movable casters 21 can also be provided at the lower end of the door 122.

[0059] In some examples, at least some of the casters 20 may be equipped with braking devices, which can be used to limit the rotation and movement of the corresponding casters 20 to reduce the movement of the corresponding casters relative to the housing 10. Optionally, the casters 20 include the aforementioned fixed casters 22 and movable casters 21, wherein the fixed casters 22 may not be equipped with braking devices, while at least some of the movable casters 21 are equipped with braking devices. In some examples, the aforementioned movable casters 21 are provided on the housing door 122 of the housing 10, and the movable casters 21 on the housing door 122 may not be equipped with braking devices.

[0060] In this example, the installation position and number of anti-collision rings 30 can be determined based on the width of the anti-collision rings 30 along the height direction of the housing 10. When the width of the anti-collision rings 30 is small, multiple anti-collision rings 30 can be set along the height direction of the housing 10.

[0061] In some examples, the thickness of the anti-collision ring 30 can be determined based on the weight of the housing 10 and the weight of the medical equipment to be housed within it. The thickness of the anti-collision ring 30 affects the area of ​​its projected outer contour in the horizontal plane. In this example, when the anti-collision ring 30, housing 10, and casters 20 are projected in the horizontal plane, the greater the thickness of the anti-collision ring 30, the larger the area of ​​its outer contour, and the larger the area of ​​the blocking region formed by the anti-collision ring 30. Consequently, the protection range of the anti-collision ring 30 for the casters 20 will also be expanded.

[0062] In some examples, there are multiple anti-collision rings 30, which are spaced apart along the height of the housing 10. In this example, each anti-collision ring 30 forms a ring-shaped protective structure on the outer side of the side wall 12. By setting multiple anti-collision rings 30, multiple protective structures can be formed at different heights of the housing 10 to reduce damage to the housing 10 and the casters 20.

[0063] Please continue reading. Figure 2 Please continue reading Figure 2 In this example, the anti-collision ring 30 adjacent to the top wall 13 can extend to the top wall 13. Optionally, the anti-collision ring 30 adjacent to the top wall 13 may not extend to the top wall 13 to facilitate operator handling. In some examples, the distance between the top wall 13 and the bottom wall 11 is a first distance H; the distance h1 between the side end face of the anti-collision ring 30 adjacent to the top wall 13 and the top wall 13 is not less than one-quarter of the first distance H. In this example, the anti-collision ring 30 protects the side wall 12 near the top wall 13 in the height direction to reduce the tilting of the top of the housing 10. The side end face of the anti-collision ring 30 adjacent to the top wall 13 can be its lower surface, and the distance between the lower surface of the anti-collision ring 30 and the top wall 13 is not less than one-quarter of the first distance to reduce the problem of the middle position of the housing 10 being hit due to excessive height of the anti-collision ring 30 adjacent to the top wall 13 in the height direction.

[0064] Please continue reading. Figure 2In this example, the anti-collision ring 30 adjacent to the bottom wall 11 can extend to the bottom wall 11; alternatively, the anti-collision ring 30 adjacent to the bottom wall 11 may not extend to the bottom wall 11 to reduce interference with the casters. In some examples, the distance between the top wall 13 and the bottom wall 11 is a first distance H; the distance h2 between the side end face of the anti-collision ring 30 adjacent to the bottom wall 11 and the bottom wall 11 is not less than one-quarter of the first distance H. In this example, the anti-collision ring 30 protects the side wall 12 near the bottom wall 11 in the height direction to reduce the collision generated by the housing 10 near the casters 20, thereby better protecting the casters 20. The side face of the anti-collision ring 30 adjacent to the bottom wall 11 facing away from the bottom wall 11 can be its upper surface. The distance h2 between the upper surface of the anti-collision ring 30 and the bottom wall 11 is not less than one-quarter of the first distance H. On the one hand, this can reduce the impact on the middle position of the box 10 in the height direction caused by the anti-collision ring 30 adjacent to the bottom wall 11 being too low. On the other hand, it can reduce the interference of the anti-collision ring 30 on the caster 20.

[0065] In some examples, the anti-collision ring 30 includes a first part 31 and a second part 32. The first part 31 is disposed around the periphery of a plurality of side panels 121, and the second part 32 is disposed on the outside of the door 122. When the door 122 is closed, the first part 31 and the second part 32 enclose and form an annular area.

[0066] In this example, multiple side panels 121 enclose a generally rectangular frame structure. This frame structure has an opening, which serves as an opening for the housing 10 to input and output medical equipment. A door 122 is used to close or open this opening. In this example, the door 122 can be connected to the side panels 121 via hinges 18. The door 122 in this example can also function as part of the side wall 12. By forming an opening on the side of the housing 10, it facilitates the input and output of medical equipment from the side, reducing the difficulty of inputting and outputting medical equipment and improving the convenience of transporting medical equipment.

[0067] The anti-collision ring 30 includes a first part 31, which and a second part 32 enclose each other to form a ring structure. The first part 31 is connected to the side plate 121 and surrounds the periphery of multiple side plates 121 to form a semi-open structure surrounding the multiple side plates 121. The second part 32 is located on the periphery of the door 122. When the door 122 is closed, the first part 31 and the second part 32 form a ring-shaped whole to form a ring surrounding the periphery of the side wall 12. In this example, the first part 31 can be generally U-shaped and can be connected to at least one side plate 121 so that the first part 31 is fixed to the side plate 121. The second part 32 can be generally U-shaped or elongated. When the door 122 is closed, the first part 31 and the second part 32 can engage with each other, and there can also be a gap between the first part 31 and the second part 32.

[0068] In some examples, the fixing component 40 includes a fixing base 41 and a buffer 42. The fixing base 41 is connected to the side plate 121 via a connector (not shown in the figure); the buffer 42 is connected to the fixing base 41 and at least partially protrudes from the side of the fixing base 41 facing the receiving cavity 15.

[0069] The fixed base 41 is used to connect and fix to the side plate 121 so that the fixing component 40 can be in a preset position. In this example, the fixed base 41 is connected to the side plate 121 through a connector, which can be a metal part such as a rivet, so that the fixed base 41 is restricted to a preset position within the housing 10, thereby reducing the possibility of the fixing component 40 falling off or becoming misaligned.

[0070] The fixed base 41 can be used to guide the medical device to define the movement trajectory of the medical device when it is moved in or out, so that the medical device can move along the trajectory formed by the fixed base 41.

[0071] In this example, the fixing base 41 can be made of a rigid material, such as wood or rigid plastic, to improve its structural strength and reduce the risk of connection failure between the fixing base 41 and the side wall 12 during installation. Alternatively, the fixing base 41 can be made of wood, steel, or alloy to further enhance its structural strength.

[0072] The buffer 42 is connected to the fixed base 41. The buffer 42 serves to cushion the area between the fixed base 41 and the medical device, reducing wear and tear on the medical device. In this example, the buffer 42 can be at least one of EVA, EPE, and PU, or other materials capable of providing cushioning and protection. The buffer 42 protrudes at least partially from the side of the fixed base 41 facing the receiving cavity 15. The buffer 42 can be located between the outer surface of the medical device and the fixed base 41. The buffer 42 can also block the area between the side of the medical device and the side plate 121, and between the upper and lower surfaces of a local structure of the medical device and the fixed base, reducing direct contact between the fixed base 41 and the outer surface of the medical device, thereby reducing wear and tear on the outer surface of the medical device. In this example, the buffer 42 can be directly installed on the outer surface of the fixed base 41, or it can be partially snapped onto the fixed base 41. In some examples, the buffer 42 is connected to the fixed base 41. In this example, the buffer 42 can be embedded in the fixed base 41, or it can be bonded to the fixed base 41 with adhesive. Alternatively, the buffer 42 can be connected to the fixed base 41 by heat fusion or inserts. In this example, by connecting the buffer 42 to the fixed base 41, the buffer 42 can be kept in a preset position within the housing 10, reducing the possibility of displacement of the buffer 42 within the housing 10. Since relative forces are generated between the medical equipment and the fixed component 40 during the insertion, removal, and transport of the medical equipment and the protective housing, this example reduces the possibility of the buffer 42 falling off, allowing the buffer 42 to better fit the medical equipment and improve the safety of medical equipment transportation.

[0073] In some examples, a fixing component 40 may also be provided on the door 122. The distance between the surface of the fixing component 40 facing the bottom wall 11 and the bottom wall 11 may not be less than the height of the rollers of the medical device. When fixing components 40 are provided on the side panel 121 and the door 122 respectively, the heights of the fixing components 40 on the side panel 121 and the door 122 may be the same or different along the height direction of the housing 10. Optionally, the shapes of the fixing components 40 on the side panel 121 and the door 122 may be the same. Optionally, the shapes of the fixing components 40 on the side panel 121 and the door 122 may be different. The difference in shape refers to at least one of the shape, size, or relative position of the fixing base 41 or the buffer 42 of the fixing component 40 being different.

[0074] Please see Figure 12In some examples, the fixed base 41 has a groove (not shown in the figure), the fixed base 41 has an opening 412 communicating with the groove, the buffer 42 is partially embedded in the groove and partially protrudes out of the outside of the opening 412.

[0075] The groove is a recess formed on the fixed base 41. Optionally, the fixed base 41 can be a hollow box, and the groove is the area formed by the hollow part inside the fixed base 41. The fixed base 41 is provided with an opening 412 communicating with the groove, so that the buffer member 42 can be inserted into the groove through the opening 412. The buffer member 42 can partially extend out of the groove, so that the buffer member 42 partially protrudes from the outside of the opening 412. In this example, the buffer member 42 can be directly snapped into the groove, the buffer member 42 can be fixedly connected to the fixed base 41, and the buffer member 42 can also be bonded to the inner wall of the groove.

[0076] In some examples, the fixed base 41 has a connecting wall 411 disposed opposite to the opening 412. The connecting wall 411 is a wall surface on the fixed base 41 that is parallel to the side plate 121, and the connecting wall is connected to the side plate 121 by a connector. The connecting wall 411 is the wall surface of the fixed base 41 adjacent to the side plate 121. In this example, by providing a groove on the fixed base 41, the connector between the fixed base 41 and the side plate 121 can be placed in the groove. The connector passing through the connecting wall 411 is connected and fixed to the side plate 121, thereby reducing the exposure of the connector inside the housing 10 and thus reducing the possibility of wear and tear on the medical device. In this example, the opening 412 on the fixed base 41 can be set on the wall surface of the fixed base 41 that is parallel to the connecting wall 411. The buffer 42 protrudes in the direction away from the connecting wall 411 so as to cooperate with the side plate 121 of the medical device, thereby reducing wear on the surface of the medical device facing the side plate 121. The opening 412 on the fixed base 41 can also be on the wall surface of the fixed base 41 that is adjacent to the connecting wall 411 so as to cooperate with any upper or lower surface of the medical device, thereby reducing wear on any upper or lower surface of the medical device.

[0077] In some examples, multiple fixing components 40 may be provided on the side plate 121, and the multiple fixing components 40 may be spaced apart along the height direction of the side plate 121.

[0078] In some examples, multiple side plates 121 may be provided with fixing components 40 respectively. The fixing components 40 on the multiple side plates 121 may correspond to different parts of the medical device. The heights of the fixing components 40 on the multiple side plates 121 may be the same or different.

[0079] In some examples, the housing 10 also includes a protective padding layer 14, which is disposed in the accommodating cavity 15. At least one of the top wall 13, bottom wall 11, door 122 and side panel 121 is provided with the protective padding layer 14. In this example, the material and thickness of the protective padding layer 14 on the top wall 13, bottom wall 11, door 122 and side panel 121 may be the same or different.

[0080] In some examples, there are multiple fixing parts 40. The fixing parts 40 are respectively provided on the side plates 121 on both sides of the door 122. The fixing parts 40 correspond to the position of the base of the medical device and are used to fit into the base of the medical device.

[0081] The side panels on both sides of the door 122 can be the two sides of the door 122 along its width direction. The door 122 can be hinged to one of the side panels 121 via a hinge 18. The door 122 can also be slidably connected to the side panel 121 or connected in other ways, so that the door 122 can close the receiving cavity 15 of the housing 10. The medical device has a base, and the rollers of the medical device can be installed under its base. Fixing components 40 are respectively provided on the side panels 121 on both sides of the door 122. When the medical device is put into the receiving cavity, the movement trajectory of the base of the medical device can be restricted by the side panels 121 on both sides of the door 122, thereby guiding the base of the medical device so that the medical device can move along a preset direction. After the medical device enters the receiving cavity, the fixing components 40 on the side panels 121 on both sides of the door 122 can be used to restrict the movement of the base of the medical device in the receiving cavity, thereby reducing the shaking of the medical device in the housing 10. In some examples, the fixing component 40 includes the fixing base 41 and the buffer 42 described above. The fixing base 41 can be made of wood, steel plate or alloy material. The rigid fixing base 41 can facilitate the connection between the fixing component 40 and the housing 10, thereby reducing the possibility of the fixing base 40 falling off. The buffer 42 is made of ethylene-vinyl acetate copolymer or polyurethane or polyethylene foam. When the base of the medical device is attached to the fixing component 40, the buffer 42 can reduce the friction between the base of the medical device and the fixing base 41, and can also provide a certain cushioning for the base of the medical device, thereby reducing the possibility of rigid contact between the base of the medical device and the housing 10.

[0082] Optionally, the fixing component 40 is also provided on the door 122. When the door 122 is closed, the fixing component 40 on the door 122 can be used to block the door 122 and the medical device to reduce wear between the door 122 and the medical device.

[0083] In some examples, at least part of the fixing component 40 is located on the side panels 121 on both sides of the door 122 near the bottom wall 11. In this example, the fixing component 40 near the bottom wall 11 can be used to limit and guide the base of the medical device or the position of the medical device near the base. In this example, the height of the fixing component 40 near the bottom wall 11 can correspond to the position of the base of the medical device, so that when the medical device is in the receiving cavity, the base of the medical device can fit against the fixing component 40, thereby reducing displacement of the base of the medical device.

[0084] Please refer to the following: Figure 15 and Figure 16 In some examples, the housing 10 also includes a ramp 112 movably connected to the bottom wall 11 or side panel 121 between a stowed position and an open position. When the ramp 112 is in the stowed position, it is located within the accommodating cavity 15. When the ramp 112 is in the open position, it is located on the same side as the door 122. One end of the ramp 112 is connected to the bottom wall 11 or side panel 121, and the other end is located on the outside of the housing 10 and extends toward the bottom wall 11 away from the top wall 13.

[0085] In this example, the door 122 is connected to at least one side panel 121 to form an opening for inputting and outputting medical devices on one side of the door 122.

[0086] The ramp 112 is designed to open when needed, forming an inclined surface on the outside of the housing 10. One end is connected to the housing 10, and the other end can contact the ground. Users can input or output medical devices along the inclined surface formed by the ramp 112. The ramp 112 has an open position and a retracted position. When the ramp 112 is in the retracted position, it can be stored in the receiving cavity 15. At this time, the ramp 112 can be suspended in the receiving cavity 15. The ramp 112 can also abut against the side panel 121 or the door 122 of the housing 10, or it can be stacked on the bottom wall 11. In this example, the ramp plate 112 is movably connected to the bottom wall 11 or the side plate 121, meaning that the ramp plate 112 can be interconnected with the bottom wall 11 or the side plate 121 and can move relative to the bottom wall 11 or the side plate 121, so that the ramp plate 112 can switch between a retracted position and an open position. Optionally, the ramp plate 112 is hinged to the bottom wall 11 or the side plate 121. In some examples, the ramp plate 112 is rotatably connected to the bottom wall 11, the bottom wall 11 including a pallet 111 and a hinge plate 114 connected to the pallet 111, the ramp plate 112 is rotatably connected to the hinge plate 114, and the caster 20 can be connected to the pallet 111. Optionally, the caster fixing plate 113 described in the above example can be provided on the end face of the pallet 111 facing away from the top wall 13 to improve the installation performance of the caster 20. In some examples, when the ramp 112 is in the retracted position, it forms an angle with the bottom wall 11. When the ramp 112 moves between the open and retracted positions, it is less susceptible to interference from the fixing components. In this example, when the ramp 112 is in the retracted position, it can fit snugly against the door 122. In some examples, a protective padding layer 14 is provided on the side of the pallet 111 facing the receiving cavity 15. In this example, the protective padding layer 14 can be made of EVA material, specifically a high-density EVA material, to improve the cushioning and shock absorption performance between the pallet 111 and the medical device. Optionally, the thickness of the protective padding layer 14 in this example can be close to or the same as the thickness of the hinge plate 114, so that when the medical device moves along the hinge plate 114 towards the inside of the housing 10, it is less likely to sway due to drastic changes in height, thus improving the stability of the medical device and reducing damage caused by vibration.

[0087] When the ramp 112 is in the open position, a portion of the ramp 112 extends outside the box 10 and towards the ground, so that the ramp 112 forms an inclined surface outside the box 10. In this example, the hinge plate 114 can be provided at the end of the pallet 111 near the box door 122, so that the connection between the ramp 112 and the hinge plate 114 is as close as possible to the edge of the bottom wall 11.

[0088] In some examples, the housing 10 also includes a first limiting member 1121 and a second limiting member 50. The first limiting member 1121 is connected to the ramp plate 112, and the second limiting member 50 is connected to the side plate 121 and extends outward from the side plate 121. The second limiting member 50 is used to connect to the first limiting member 1121 when the ramp plate 112 is in the retracted position to restrict the ramp plate 112 from moving to the open position.

[0089] The first limiting member 1121 and the second limiting member 50 can be connected to each other. When the first limiting member 1121 and the second limiting member 50 are connected to each other, the ramp 112 is limited to a preset position in the box 10. In this example, the first limiting member 1121 and the second limiting member 50 can be a buckle, screw, magnetic component, Velcro, or other components that can be used to limit the ramp 112 to the storage position of the box 10. Taking a magnetic component as an example, in this example, one of the first limiting member 1121 and the second limiting member 50 can be at least partially a magnet, and the other can be a magnetically attractive structure, so that when the ramp plate 112 is in the retracted position, the first limiting member 1121 and the second limiting member 50 can attract each other to restrict the movement of the ramp plate 112; taking the second limiting member 50 as at least partially a magnet as an example, the second limiting member 50 can be at least partially a magnet connected to the surface of the side plate 121, and the second limiting member 50 can be provided to protrude from the surface of the side plate 121. When the ramp plate 112 is in the retracted position, the first limiting member 1121 can be provided opposite to the side plate 121 so that the second limiting member 50 can attract each other to the first limiting member 1121.

[0090] The second limiting member 50 is connected to the side plate 121, meaning that the second limiting member 50 is fixedly or detachably connected to the side plate 121. The second limiting member 50 extends outward from the side plate 121, meaning that the second limiting member 50 can partially protrude beyond the outer side of the side plate 121. The portion of the second limiting member 50 protruding beyond the side plate 121 can be used to connect with the first limiting member 1121 to prevent the first limiting member 1121 from moving to the open position. In this example, the second limiting member 50 is a long strip structure. One end of the second limiting member 50 in the length direction can be connected to the side plate 121. When the ramp plate 112 is in the retracted position, the second limiting member 50 can be connected to the first limiting member 1121, so that the first limiting member 1121 and the second limiting member 50 block the ramp plate 112 on the side away from the receiving cavity 15, thereby generating a force on the ramp plate 112 towards the receiving cavity 15 to prevent the ramp plate 112 from moving to the open position. In this example, by setting the first limiting member 1121 and the second limiting member 50 in combination, the ramp plate 112 can be limited so that the ramp plate 112 can be kept in the storage position. On the one hand, it can reduce the swaying of the ramp plate 112 relative to the box 10; on the other hand, when the staff opens the box door 122, it can reduce the risk of the ramp plate 112 shifting to the open position and causing injury to personnel.

[0091] In some examples, the side panel 121 is provided with the fixing component 40 described in any of the above examples, and the side panels 121 on both sides of the door 122 are provided with fixing components 40, wherein at least some of the fixing components 40 are provided close to the bottom wall 11. When the ramp 112 is in the storage position, the fixing component 40 can block the inside of the ramp 112 to limit the tilt angle of the ramp 112 toward the inside of the receiving cavity 15. Optionally, when the ramp 112 is in the retracted position, the ramp 112 can be perpendicular to the bottom wall. The fixing component 40 can prevent the ramp 112 from tilting inward toward the receiving cavity 15, thereby reducing the possibility of the ramp 112 causing damage to the medical device. In this example, the fixing component 40 can also exert a force on the ramp 112 to move in the open position. When the first limiting member 1121 is connected to the second limiting member 50, the first limiting member 1121 and the second limiting member 50 prevent the ramp 112 from tilting outward toward the box 10, thereby limiting the ramp 112 from both the inner and outer sides to reduce unnecessary shaking of the ramp 112, keep the ramp 112 upright, and improve the stability of the ramp 112.

[0092] In some examples, the first limiting member 1121 and the second limiting member 50 are both Velcro. In this example, one of the first limiting member 1121 and the second limiting member 50 can be a fleece structure in Velcro, and the other can be a hook-and-loop structure in Velcro, which limits the ramp plate 112 through the cooperation of the Velcro. Optionally, the first limiting member 1121 can be provided on the side surface of the ramp plate 112 facing the receiving cavity 15 when it is in the storage position, and the first limiting member 1121 can also be provided on the side surface of the ramp plate 112 facing away from the receiving cavity 15 when it is in the storage position.

[0093] Please refer to the following: Figure 13 and Figure 14 In some examples, the protective case also includes an accessory module 60, which is movably disposed within the receiving cavity 15. In this example, the accessory module 60 can be placed within the gaps between different parts of the medical device. The accessory module 60 can prevent vibrations from the medical device and can also store accessories for the medical device. The accessory module 60 in this example can be packaged using at least one of EVA and PU foam, or other materials that provide cushioning and protection.

[0094] In some examples, the housing 10 also includes the ramp 112 described in any of the above examples. An accessory module 60 can be provided inside the housing 10 at a position corresponding to the ramp 112. The accessory module 60 can block the medical device from tilting inwards towards the housing 10, thus preventing damage to the medical device. In some examples, fixing components 40 are provided on the side panels 121 on both sides of the door 122. At least some of the fixing components 40 are located near the bottom wall 11. When the ramp 112 is in the retracted position, the accessory module 60 is positioned between the fixing components 40 and the ramp 112. The accessory module 60 can block the ramp 112 from tilting inwards, reducing damage to the medical device and fixing components 40. Furthermore, the accessory module 60 can exert an outward force on the ramp 112, keeping it upright.

[0095] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
