[0025] refer to Figure 1 .

[0026] In this specific embodiment, a movable CT bed protective curtain is provided, comprising a base 1, an intermediate layer 2 and a movable curtain 3;

[0027] The base 1 is configured to be embedded in the CT bed; the middle layer 2 is in a rectangular shape, mounted on the base 1 and connected thereto, and the middle layer 2 is provided with an active channel 21 that runs through the width direction of the middle layer 2; the movable curtain 3 is passed through the active channel 21, and the width of the active channel 21 is greater than the width of the movable curtain 3, so that the movable curtain 3 can move along the length direction of the middle layer 1 in the active channel 21, and the two ends of the movable curtain 3 are detachably connected to form a 360-degree surrounding coverage for the person being tested. In specific implementation, the base 1 and the middle layer 2 can be correspondingly set to a humanoid contour shape based on a rectangle, and the bottom of the base 1 is set to be arc-shaped to adapt to the upper surface of the CT bed, so that the base 1 can be easily embedded in the CT bed, and the upper surface of the base 1 is set to be a plane to facilitate the installation of the middle layer 2 on the base 1, and the acrylic sheet can be selected as the specific material to make the base 1 and / or the middle layer 2.

[0028] In one specific embodiment, it also includes a plurality of pairs of Velcro connectors (not shown) and Velcro joints (not shown); each pair of Velcro connectors / Velcro joints are evenly spaced and cover the entire engaging surface of the base 1 and the CT bed, each Velcro connector is arranged on the CT bed and fixedly connected thereto, and each Velcro joint is arranged on the bottom of the base 1 and fixedly connected thereto; when the base 1 and the CT bed are engaged together, each Velcro connector is adhered to its corresponding Velcro joint; when the base 1 is removed from the CT bed, each Velcro connector is detached from its corresponding Velcro joint. Since the base 1 is embedded in the external CT bed, the subject may grasp it incorrectly or be pulled by the body when lying on the middle layer 2 or getting up from the middle layer 2, and the base 1 may be dislocated or dislocated due to the force. Therefore, in this specific embodiment, a pair of connecting members and joining members are provided, and the connecting members are used to connect the external CT bed, and the joining members are used to connect the base 1. When the base 1 is embedded in the CT bed, the connecting members and the joining members are assembled and connected to form a whole, thereby strengthening the connection strength between the base 1 and the CT bed, so as to avoid dislocation or misalignment of the base due to misoperation of the subject as much as possible.

[0029] In other specific implementations, various mutually adaptable connectors and joints such as slot / snap-on type, glue-coated and adhesive type can be selected and applied.

[0030] In this specific embodiment, the movable channel 21 is opened on the bottom surface of the middle layer 2, and the middle layer 2 is fixedly connected to the base 1; the upper part of the middle layer 2 is provided with a lying plane for the person being tested to lie down. Specifically, it is a sunken through groove opened on the bottom surface of the middle layer 1. After the middle layer 2 is placed on the base 1, the sunken through groove will be enclosed with the upper surface of the base 1 to form a through movable channel, and the movable curtain 2 can pass through the through channel. A sponge cushion is laid on the lying plane of the middle layer 2 to provide a more comfortable lying experience for the person being tested. Compared with directly opening a through movable channel 21 in the middle layer 2, the process of opening a lower sunken through groove on the bottom surface of the middle layer 2 and enclosing it with the upper surface of the base 1 to form a through movable channel 21 is simpler and more efficient. After the person being tested lies down on the lying plane at the upper part of the middle layer 2, the movable channel 21 opened perpendicular to the width direction of the middle layer 2 provides a movable space for the movable curtain 3. The movable curtain 31 can fully wrap the non-irradiated part of the person being tested from the bottom to the top of the person being tested's lying position through the movable channel 21, providing 360-degree radiation protection for the person being tested.

[0031] In this specific embodiment, it also includes a slide rail 4, which is laid in the movable channel 21 along the length direction of the middle layer 2, and the slide rail 4 is fixedly connected to the base 1. The movable curtain 4 includes a leaded curtain body 31 and at least one slider 32, the slider 32 is arranged below the leaded curtain body 31, the slider 32 is fixedly connected to the leaded curtain body 31, the leaded curtain body 31 is passed through the movable channel 21, and the slider 32 is embedded in the slide rail 4 and reciprocates along the slide rail 4.

[0032] In this specific embodiment, the length of the lead curtain 31 is greater than twice the width of the CT bed. In specific settings, the length of the lead curtain 31 can be appropriately extended to wrap subjects of different body shapes as much as possible. If the width of the lead curtain 31 is set to be smaller than the width of the active channel 21, the lead curtain 31 can easily slide in the active channel 21 and constantly change its position to cover the designated part of the subject. If the length of the lead curtain 31 is set to be greater than twice the width of the external CT bed, the operator can use the lead curtain 31 to easily wrap the non-irradiated part of the subject, providing comprehensive radiation protection for the subject.

[0033] In one specific embodiment, the lead-containing curtain 31 is relatively long. After the subject lies on the middle layer 2, the operator cross-overs and overlaps the two ends of the lead-containing curtain 31 to cover the non-irradiated part of the subject.

[0034] In another specific embodiment, the length of the lead curtain body 31 is shorter, and the movable curtain 3 also includes a closing piece (not shown) and a locking piece (not shown) arranged in pairs, the closing piece is arranged at one end of the lead curtain body 31 and fixedly connected thereto, the locking piece is arranged at the other end of the lead curtain body 31 and fixedly connected thereto, and the closing piece and the locking piece are detachably connected so that the two ends of the lead curtain body 31 can be joined or disassembled. After the person being tested lies on the middle layer 2, the operator aligns the two ends of the lead curtain body 31, and correspondingly engages the closing piece and the locking piece to connect the two ends of the lead curtain body 31. After the test is completed, the operator disassembles the closing piece and the locking piece, and the person being tested can get up and leave. In specific real time, specific pulling and closing tools such as zippers, buttons, and cables can be selected and applied therein.

[0035] In this specific embodiment, the movable curtain 3 further includes a hard support plate (not shown), which is arranged between the slider 32 and the lead-containing curtain body 31 to support the lead-containing curtain body 31, and the hard support plate is fixedly connected to the slider 32. The lead-containing curtain body 31 has a large mass, and the hard support plate is arranged on the slider 32. On the one hand, it can support the large mass of the lead-containing curtain body 31 to prevent the lead-containing curtain body 31 from being deformed and drooping due to gravity. On the other hand, the hard support plate is not easy to deform. After being fixedly connected to the slider 32, it moves back and forth on the slide rail 4 together with the slider 32. The operator can easily drag the lead-containing curtain body 31 by pulling the part of the lead-containing curtain body 31 extending from the movable channel 21, and drive the hard support plate and the slider 32 to move back and forth along the slide rail 4, so as to facilitate the change of the specific position of the lead-containing curtain body 31 to cover different non-irradiated parts of the subject.

[0036] In this specific embodiment, the slide rail 4 includes a first slide rail 41 and a second slide rail 42. The first slide rail 42 is laid in the movable channel 21 along the length direction of the middle layer 2 and is fixedly connected to the base 1. The second slide rail 42 is laid on one side of the first slide rail 41 along a direction parallel to the first slide rail 41 and is fixedly connected to the base 1; the slider 32 includes three first sliders 321 and three second sliders 322, each first slider 321 is fixedly connected to the lead-containing curtain body 31, and each first slider 321 is embedded in the first slide rail 41; each second slider 322 is fixedly connected to the lead-containing curtain body 31, and each second slider 322 is embedded in the second slide rail 42.

[0037] In this specific embodiment, both side edges of the hard support plate are fixedly connected to the first slider 321 and the second slider 322 respectively.

[0038] When in use, the operator can first open the movable curtain 3 and guide the subject to lie on the middle layer 2. After the subject lies stably, the operator pulls the movable curtain 3 along the movable channel 21 according to the position of the non-irradiated part of the subject that needs to be covered, and overlaps or closes the two ends of the movable curtain 3 and covers the subject to complete the operation. At this time, the movable curtain can not only cover the side of the subject's body facing the CT device, but also cover the side and back of the subject in all directions, and wrap the non-irradiated part of the subject in 360 degrees in all directions, providing a safe, secure and comprehensive protection for the subject. After the CT scan is completed, the operator only needs to lift the movable curtain 3 or disassemble the movable curtain 3 that was originally closed, and the subject can easily get up and leave from the middle layer 2. The whole operation process is simple and convenient, with low operating difficulty, and the work efficiency of the operator can be greatly improved. The subject is wrapped by the movable curtain 3, and the back, side and front of the non-irradiated part of the subject are also protected 360 degrees, which can minimize the impact of the radiation of the CT device on the non-irradiated part of the subject.

[0039] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
