Description

Technical Field

[0001] This utility model relates to the field of medical equipment, and in particular to a lifting device for a medical examination bed and a medical examination bed including the device. Background Technology

[0002] Currently, most medical scanning equipment on the market, such as CT and MRI machines, uses parallelogram or scissor-fork structures to achieve their lifting functions. However, these structures are not only complex, but the required thrust changes constantly during the lifting process, making it impossible for the examination bed to rise and fall smoothly.

[0003] While the direct lifting structure requires a constant thrust, it does require a large thrust. Furthermore, because the examination bed moves in a straight up-and-down motion, its horizontal travel is very limited, which restricts the horizontal scanning range of the medical scanning equipment. Utility Model Content

[0004] The purpose of this invention is to provide a lifting device for a medical examination bed, which requires a constant thrust and can increase the scanning stroke of the medical scanning equipment in the horizontal direction.

[0005] Another objective of this invention is to provide a medical examination bed that includes the aforementioned lifting device, which requires a constant thrust and can increase the scanning stroke of the medical scanning equipment in the horizontal direction.

[0006] The lifting device for the medical examination bed provided by this utility model includes a base and a support member. The medical examination bed also includes a bed body. The support member is used to support the bed body and is movably connected to the base in a direction at an angle to the height direction, so as to lift the bed body in the height direction and its opposite direction.

[0007] By configuring the support members to be movably connected to the base in a direction at an angle to the height direction to raise and lower the bed, the lifting device requires a constant thrust during the raising and lowering of the bed, while the bed also displaces horizontally during the raising process, thereby increasing the scanning stroke of the medical scanning equipment in the horizontal direction.

[0008] In another illustrative embodiment of the lifting device for a medical examination bed, the base includes a support beam inclined relative to the height direction. A support member is movably connected to the support beam along its length and in the opposite direction. This facilitates the installation of the support member.

[0009] In another illustrative embodiment of the lifting device for the medical examination bed, a drive unit is also included. The drive unit is mounted on the base and has a thrust output section. A support member is fixedly connected to the thrust output section. The drive unit can apply a thrust along the length direction to the support member through the thrust output section. This allows the bed body to be raised or lowered by applying a thrust along the length direction to the support member.

[0010] In another illustrative embodiment of the lifting device for a medical examination bed, the drive unit includes a ball screw. The thrust output is a flange nut of the ball screw, and both ends of the ball screw are rotatably connected to the base. This structure is simple and easy to install.

[0011] In another illustrative embodiment of the lifting device for a medical examination bed, the base includes two parallel support beams. The lifting device also includes two pairs of guide rails. The support member is movably connected to the two support beams via the two pairs of guide rails. Each support beam is provided with a guide rail, and each slider is fixedly connected to the support member. This facilitates the improvement of the stability of the support member's movement, and the structure is simple and easy to install.

[0012] In another illustrative embodiment of the lifting device for a medical examination bed, the base also includes a seat. Each support beam is fixedly connected to the seat via its lower surface perpendicular to its length. A guide rail is provided on the upper surface of each support beam perpendicular to its length. This improves the overall stability of the lifting device and facilitates installation.

[0013] In another illustrative embodiment of the lifting device for a medical examination bed, at least one support beam is provided with two stops. The two stops are spaced apart on the support beam along the movement trajectory of the thrust output section to limit the travel of the support member. This facilitates limiting the travel of the support member.

[0014] In another illustrative embodiment of the lifting device for the medical examination bed, a cover plate is also included. The support member further includes a drive connection portion and a base connection portion. The drive connection portion is fixedly connected to the thrust output portion, and the base connection portion is fixedly connected to the drive connection portion and the slider. A gap is provided between the base connection portion and the drive connection portion in a direction perpendicular to the length direction. The cover plate is inserted into the gap along the length direction and its two ends are fixedly connected to the base to cover the space below the two support beams in the height direction. This prevents droplets and dust from entering the space below the two support beams in the height direction.

[0015] In another illustrative embodiment of the lifting device for the medical examination bed, a cable chain is also included. One end of the cable chain is connected to a support beam. The other end of the cable chain is connected to a drive connector to move relative to the base in a direction parallel to its length. This prevents the cable from becoming tangled.

[0016] This invention also provides a medical examination bed, which includes a bed body and the aforementioned lifting device in sequence along the height direction. The lifting device is fixedly connected to the bed body and configured to lift the bed body in the height direction and its opposite direction. The medical examination bed requires a constant thrust and can increase the scanning stroke of the medical scanning equipment in the horizontal direction. Attached Figure Description

[0046] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, specific embodiments of the present utility model are now described with reference to the accompanying drawings, in which the same reference numerals denote the same parts.

[0047] In this document, “illustrative” means “serving as an example, illustration or description”, and any illustration or implementation described herein as “illustrative” should not be construed as a more preferred or advantageous technical solution.

[0048] In this document, terms such as "first" and "second" do not indicate their importance or order, but are only used to distinguish them to facilitate the description of the document.

[0049] In this article, terms such as "upper," "lower," "inner," and "outer" are used only to indicate the relative positional relationship between related parts, rather than to define the absolute position of these related parts.

[0050] To keep the drawings simple, each drawing only schematically shows the parts related to this utility model, and they do not represent the actual structure of the product.

[0051] Figure 1 This is a schematic diagram illustrating one embodiment of a medical examination bed. The medical examination bed is, for example, a CT scan bed, but it is not limited to this; it can also be an examination bed for other medical scanning devices, or a hospital bed, operating table, etc. See also Figure 1 In the illustrative embodiment, the lifting device of the medical examination bed includes a base 10 and a support member 20. The medical examination bed also includes a bed body 90. The support member 20 is used to support the bed body 90, and the support member 20 forms an inclination angle (inclination angle) with respect to the height direction H. Figure 1 The bed 90 is movably connected to the base 10 in the direction not shown in the diagram, so as to raise and lower the bed 90 along the height direction H and its opposite direction.

[0052] By configuring the support members to be movably connected to the base in a direction at an angle to the height direction to raise and lower the bed, the lifting device requires a constant thrust during the raising and lowering of the bed, while the bed also displaces horizontally during the raising process, thereby increasing the scanning stroke of the medical scanning equipment in the horizontal direction.

[0053] Specifically, medical examination beds can be used through methods such as Figure 2 The lifting device shown is used to lift the bed body 90. Wherein, Figure 2 For illustrative purposes Figure 1 A schematic diagram of one embodiment of the lifting device for the medical examination bed shown.

[0054] See Figure 2 The base 10 includes two parallel support beams 11 that are inclined relative to their height direction H. The direction of inclination with respect to the height direction H is the length direction L of the support beam 11 and the opposite direction of the length direction L. The base 10 also includes a seat 14. The support beams 11 pass through their lower surfaces perpendicular to the length direction L (i.e., Figure 2 The lower surface of the middle support beam 11 is fixedly connected to the base 14. The upper surface of each support beam 11 perpendicular to the length direction L (i.e., Figure 2 A guide rail 41 is provided on the outer surface of the upper side wall of the central support beam 11. Two sliders 42 cooperate with one guide rail 41 to form a guide rail pair 40. Figure 2 (Only one is schematically shown in the diagram), and the two sliders 42 are fixedly connected to the support member 20. The support member 20 is movably connected to the support beam 11 along the length direction L and the opposite direction. The support member 20 is mounted on the two support beams 11, which helps to improve the overall stability of the lifting device and facilitates installation. The number of support beams 11 can also be only one.

[0055] Figure 3 For explanation Figure 2 The connection relationship between the support components and the drive unit in the lifting device shown. (See also...) Figure 3 In this illustrative embodiment, the lifting device further includes a drive unit 30. The drive unit 30 is, for example, a ball screw motor including a motor and a ball screw. The drive unit 30 has a thrust output section 31. The thrust output section 31 is, for example, a flange nut of the ball screw. The base 10 also includes a first support 12 and a second support 13. The first support 12 and the second support 13 are respectively located at both ends of the base body 14 along the length direction L. One end of the ball screw is connected by a bolt (with its axis parallel to the length direction L). Figure 4(Only one is schematically shown) The first support 12 is rotatably connected, and the other end of the ball screw is rotatably connected to the second support 13 by a bolt whose axis is perpendicular to the length direction L. The motor is fixedly connected to the second support 13 by a bolt whose axis is perpendicular to the length direction L. Thus, the ball screw motor is mounted on the base 10 along the length direction L.

[0056] The support member 20 also includes a drive connection part 21, through which the thrust output part 31 is fixedly connected. The drive connection part 21 is connected by bolts whose axis is parallel to the length direction L. Figure 4 Only one schematic diagram shows a fixedly connected thrust output unit 31. The drive unit 30 can apply a thrust along the length direction L to the support member 20 through the thrust output unit 31 to raise and lower the bed 90. This structure is simple and easy to install. However, it is not limited to this. In other illustrative embodiments, the drive unit 30 can also be other power mechanisms, and the support member 20 can also be connected to the thrust output unit 31 through other structures.

[0057] The support member 20 also includes two base connecting parts 22. Each base connecting part 22 and the drive connecting part 21 are connected sequentially along a direction perpendicular to the length direction L. Each base connecting part 22 is connected to two sliders 42 at both ends perpendicular to the length direction L, and each base connecting part 22 is fixedly connected to the upper surface of the two sliders 42 along the direction perpendicular to the length direction L (i.e., Figure 2 (Upper surface of slider 42). In other illustrative embodiments, the number of base connecting parts 22 can be adjusted as needed, and the number of sliders 42 in a guide rail pair 41 can also be flexibly adjusted according to the actual application scenario.

[0058] The support component 20 also includes a bed connecting part 23 and a support body 24. The bed connecting part 23, the support body 24, the base connecting part 22, and the drive connecting part 21 are connected sequentially along the height direction H. The bed connecting part 23 is used to connect the bed 90. This structure is simple and easy to install.

[0059] Figure 4 for Figure 2 A partial sectional view along IV-IV. See also... Figure 4 It clearly shows the connection and positional relationships between the various structures of the lifting device. Combined with... Figure 3 and Figure 4In this illustrative embodiment, the support beam 11 is a square tube, but it is not limited to this; the support beam 11 can also be other mechanical structures. The lifting device also includes a cover plate 50. A gap S is provided between the base connecting part 22 and the drive connecting part 21 along the length direction L. The cover plate 50 is inserted into the gap S along the length direction L and its two ends are fixedly connected to the base 10 to cover the space below the two support beams 11 along the height direction H. This prevents droplets and dust from entering the space below the two support beams 11 along the height direction H.

[0060] Figure 5 For illustrative purposes Figure 2 A partial structural diagram of the lifting device is shown. See also... Figure 5 In this illustrative embodiment, two block-shaped stops 111 are spaced apart along the length direction L on a support beam 11 near the drive unit 30 of the lifting device. Of course, the shape of the stops 111 can also be other shapes. Each stop 111 is arranged on the support beam 11 along the movement trajectory of the thrust output part 31, so as to limit the movement stroke of the thrust output part 31 between the two stops 111, thereby limiting the movement stroke of the support member 20. Figure 5 As shown, the thrust output section 31 is compared to Figure 3 At that time, the position had moved in the opposite direction of the length direction L to the lower end of the travel along the height direction H.

[0061] The lifting device also includes a cable drag chain 60. In this illustrative embodiment, as... Figure 5 As shown, one end of the cable drag chain 60 is connected to the support beam 11. The other end of the cable drag chain 60 is connected to the drive connection part 21 to move relative to the base 10 in a direction parallel to the length direction L. This prevents the cable 60 from getting tangled during movement with the thrust output part 31. This invention also provides a medical examination bed, which includes a bed body 90 and the aforementioned lifting device in sequence along the height direction H. The lifting device is fixedly connected to the bed body 90 and configured to lift the bed body 90 along the height direction H and its opposite direction.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
