Description

Technical Field

[0001] The utility model relates to the medical field, in particular to a patient supporting device for CT examination. Background Art

[0002] CT scans a specific layer of thickness within a specific part of the human body using an X-ray beam. The scan requires one or more rotations to obtain all the raw data needed for reconstruction. Conventional CT scans require the patient to lie supine. The CT machine uses the supine image as a reference to mark the left and right sides of the image. Therefore, CT scans are generally performed in conjunction with a patient support couch.

[0003] Conventional CT scanners often come with a separate patient support bed, which requires adjustment to align with the CT mainframe. When relocating the CT scanner, the patient support bed and mainframe must be moved separately and then reinstalled. Both must be repositioned for optimal use, making installation and calibration cumbersome. Furthermore, these separate patient support beds are expensive, heavy, and require significant floor space.

[0050] The mobile support frame 1 is connected and fixed with the bottom of the CT machine through the support frame connecting mechanism 2, and the horizontal movement of the mobile support frame 1 is realized. The support frame connecting mechanism 2 in the present application can be a horizontal movement connecting mechanism, can be a rotary connecting mechanism, and can also be a combination of the horizontal movement connecting mechanism and the rotary connecting mechanism. In the specific embodiment as shown in Figure 4 and Figure 5 In one specific embodiment as shown, the support frame connecting mechanism 2 is a horizontal movement connecting mechanism.

[0051] The shape and material of the bed plate 11 are not specifically limited in the technical solution, and any bed plate 11 that can be applied to CT detection in the prior art can be used.

[0052] Specifically, the number of the lifting mechanism 12 is at least two. The lifting and support of the bed plate 11 are more stable. The number includes but is not limited to 3, 4, etc., which will not be described here, as long as the bed plate 11 can be stably supported.

[0061] In a Figure 5 In the specific embodiment shown, there are two guide mechanism fixing plates 131 for stably fixing the guide shaft 132 .

[0062] Specifically, if Figure 5 As shown, the support frame connection mechanism 2 further specifically includes a linear bearing 25; the guide shaft 132 passes through the linear bearing 25 to further ensure the horizontal linear motion of the guide shaft 132.

[0063] The number of the linear bearings 25 and the guide shafts 132 in the technical solution of the present application is not limited, and the linear bearings 25 can be as follows: Figure 5 As shown in FIG4, the guide shaft 132 can be as follows Figure 5 The two shown can also be one, three, etc. As long as they can provide stable support for the entire patient support device and can drive the bed plate 11 to move horizontally.

The guide mechanism connection member 22 drives the guide shaft 132 to move horizontally synchronously. The guide shaft 132 drives the lifting mechanism 12 to move horizontally synchronously through the guide mechanism fixing plate 131 and the lifting adapter plate 123, thereby achieving horizontal movement of the bed plate 11.

[0072] Specifically, if Figure 3 and Figure 4As shown, in actual use, the movable support frame 1 is first installed and fixed via the support frame connection mechanism 2. After installation, the lifting mechanism 12 is activated to adjust the height of the bed plate 11. The driving member 24 is activated to move the movable member 23 connected to the guide mechanism connection member 22, thereby moving the guide shaft 132 through the guide mechanism connection member 22, thereby driving the bed plate 11 to move synchronously to adjust the bed plate to the appropriate position. If the CT machine needs to be moved later, the patient support device can be moved as a whole with the CT machine because it is integrally connected to the CT machine.

[0073] In summary, the patient support device for CT examination provided by the present invention realizes an integrated connection with the CT machine, avoiding the trouble of installing and calibrating the support bed after the CT machine and the support bed are moved separately in the prior art. In addition, the patient support device of the present invention is small in size, occupies a small area, and has a low manufacturing cost.
