Detailed Description

For a more clear understanding of the technical features, objects, and effects of the present disclosure, embodiments of the present disclosure will now be described with reference to the accompanying drawings, in which like reference numerals refer to like parts throughout.

"exemplary" means "serving as an example, instance, or illustration" herein, and any illustration, embodiment, or steps described as "exemplary" herein should not be construed as a preferred or advantageous alternative.

For the sake of simplicity, only the parts relevant to the present disclosure are schematically shown in the drawings, and they do not represent the actual structure as a product. In addition, in order to make the drawings concise and understandable, components having the same structure or function in some of the drawings are only schematically illustrated or only labeled.

In this document, "one" means not only "only one" but also a case of "more than one". In this document, "first", "second", and the like are used only for distinguishing one from another, and do not indicate the degree of importance and order thereof, and the premise that each other exists, and the like.

In the conventional scanning table for medical imaging, as shown in fig. 1, a gap between a scanning table 50 applied to CT or MR and a guide rail 22 guiding the scanning table to move on a bed 20 needs to be greater than 25mm or less than 4 mm. During the movement of the scanning table 50 on the guide rails 22, there is a risk of the patient being pinched if he or she carelessly places his or her hand on the end surface of the scanning table 20, since a scissor-like shearing movement is created between the scanning table and the guide rails.

Other scanning bed boards usually use detachable anti-pinch components, which are easily lost or damaged when falling off. For this purpose, a fixed anti-pinch component may also be used for the scanning table 70, as shown in fig. 2a and 2b, for example, the current fixed anti-pinch component 72 is relatively rigidly fixed to the scanning table 70. Therefore, when the scanning table 70 moves on the guide rail 22 or moves to a guide rail close to a body coil, since the weight of a part of the object to be inspected acts on the scanning table 70, and the scanning bed is heavy, the scanning table 70 is deformed to a certain extent in the vertical direction of the scanning table 70 due to the action of gravity, and the fixed hand-pinching preventing member 72 collides with the guide rail 22, thereby damaging the scanning table.

In the following, the scanning bed board provided by the present disclosure is described in detail with reference to the accompanying drawings and specific embodiments, in consideration of the fact that the anti-hand-clipping anti-collision block can move backwards under the action of the reset component when the scanning bed board bears a load, so as to prevent the anti-hand-clipping anti-collision block from directly colliding with the guide rail on the bed body, thereby simultaneously performing the anti-collision and anti-hand-clipping functions.

Fig. 3 is a partial schematic view of a scanning couch board according to an exemplary embodiment of the present disclosure.

As shown in fig. 3, the scanning table 10 is configured to support an inspection object, and includes: a sliding member (not shown) configured to be disposed corresponding to and slidably engaged with the guide rail 22 of a bed 20, the scanning bed 10 being slidably displaced along the guide rail 22 by means of the sliding member, the scanning bed 10 further comprising: at least one anti-pinch anti-collision block 12 can be arranged opposite to the guide rail 22, and the anti-pinch anti-collision block 12 is arranged at the position of one end part of the scanning bed board 10 and shields the area between the guide rail 22 and the scanning bed board 10, so that the scanning bed board 10 slides and displaces towards the anti-pinch anti-collision block 12 in the sliding fit process with the guide rail 22, and here, the anti-pinch anti-collision block 12 keeps a clearance smaller than 4.0mm (millimeter) with the guide rail 22 when the scanning bed board does not bear load, for example, so as to accord with the effect of preventing pinching; the cavity 16 is correspondingly arranged at the position of the hand-clamping-preventing anti-collision block 12, the cavity 16 comprises an opening, and the hand-clamping-preventing anti-collision block 12 moves into the cavity 16 through the opening; and a restoring member 14 configured to act on the hand-clamping prevention bump 12, so that when the scanning bed board 10 is guided for sliding displacement on the guide rail 22, for example, in the moving direction F, the scanning table 10 is coupled with the guide rail 22 to be guided to perform a sliding movement thereon, the anti-pinch anti-collision block 12 moves into the chamber 16 under the interaction force with the guide rail 22 to press the restoring member 14 to deform, for example, the scanning table 10 deforms downward under the load, namely, the force of the load vertically acts on the scanning bed plate 10 to make the anti-pinch anti-collision block 12 move downwards, taking the MR scanning bed body as an example, after the scanning bed 10 enters the body coil, it may contact and collide with the guide rail 22 of the body coil, that is, the force of the guide rail 22 on the scanning bed plate 10 will immediately conduct to the anti-hand-pinching anti-collision block 12, so as to trigger the reset component to be compressed or squeezed, and the anti-hand-pinching anti-collision block 12 will move backward to avoid the collision with the guide rail 22. Here, the return member 14 includes a return spring.

In addition, for example, after the scanning bed plate 10 enters a body coil, for example, when the sliding part moves to couple with the guide rail 22 for sliding displacement, the force between the anti-pinch collision block 12 and the guide rail 22 is small, i.e., the anti-pinch collision block is separated from the contact with the guide rail 22 and is reset under the reset action of the reset part 14, e.g., a reset spring, i.e., the anti-pinch collision block 12 returns to the original position and maintains a gap of less than 4.0mm, for example, between the bed body 20 (including the guide rail 22) to perform the anti-pinch function.

According to an illustrated embodiment, the anti-pinch anti-collision block 12 of the scanning bed board 10 includes a first contact surface 122 configured to contact the guide rail 22, a second contact surface 124 configured to slidably contact a first surface 162 of the chamber 16, and a first limiting portion 161 disposed on the first surface 162 and limiting the second contact surface 124, so that the anti-pinch anti-collision block 12 can only move towards the inside of the chamber 16; the restoring element 14 is designed to act between the hand-protection impact protection 12 and a second surface 164 of the chamber 16, for example, the second surface 164 can be designed as a vertical surface and can be pressed or compressed in the direction of the forced movement of the hand-protection impact protection 12 into the chamber 16, for which purpose it can be designed with a certain inclination.

According to another embodiment, the anti-hand-clipping and anti-collision block can be configured in different shapes and the reset component can also be configured in different positions to provide elastic force and reset force for the stressed anti-hand-clipping and anti-collision block, for this reason, as shown in fig. 4a-4c, another embodiment of the scanning bed board 30 is shown, the side surfaces of the anti-hand-clipping and anti-collision block 32 of the scanning bed board 30, i.e. the side surfaces facing the guide rail 20 relative to the anti-hand-clipping and anti-collision block 32 can be respectively configured with a limit component 31 for limiting with the chamber 36, the reset component 34 is arranged along the limit component 31, for example, sleeved on the limit component 31 through a reset spring, and is accommodated in the second limit portion 361 arranged opposite to the chamber 36 for limiting, so that the anti-hand-clipping and anti-collision block 32 moves down and deforms under the mutual acting force between the guide rail 22 of the bed body 20, for example, the scanning bed board 30 bears a certain load force, after the anti-hand-clipping anti-collision block 32 contacts with the guide rail 22, the anti-hand-clipping anti-collision block 32 can rotate along the limiting component 31 to move towards the cavity 36 and press the reset component 34, for example, the reset spring is deformed, so that the anti-hand-clipping anti-collision block 32 moves towards the cavity 36, and the anti-hand-clipping anti-collision block 32 is prevented from colliding with the guide rail 22 to damage the guide rail 22. Here, the stopper member 31 may be provided as a cylinder.

According to the illustrated embodiment, the anti-pinch block 32 may be configured to include a first contact surface 322 configured to rotate under an external force on the anti-pinch block 32 and then contact the guide rail 22, and a second contact surface 324 configured to face the cavity 36 and configured as a convex arc surface to rotate the anti-pinch block 32 after being forced to be received in the cavity 36.
