[0024] In order to make the skilled in the art better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

[0025] Please refer to Figures 1-7 The adjustable CT detection auxiliary fixing device provided by the embodiment of the present application comprises a bed body 1, and further comprises a fixing unit arranged on each side of the bed body 1, each fixing unit comprises a sliding rod 2, a clamping member 3 and a locking member 4, the sliding rod 2 is horizontally and slidingly connected to the bed body 1; the clamping member 3 is horizontally and slidingly connected to the sliding rod 2, and the clamping member 3 is used for clamping and fixing an arm; the locking member 4 is used for relatively locking and fixing the sliding rod 2 and the bed body 1, specifically, the clamping member 3 comprises a bearing block 31, a bidirectional screw 32 and two clamping plates 33, the bearing block 31 is axially and slidingly connected to the sliding rod 2; the bidirectional screw 32 is rotationally connected to the bearing block 31, and the bidirectional screw 32 comprises a first threaded section 321 and a second threaded section 322; the two clamping plates 33 are slidingly connected to the bearing block 31, and the two clamping plates 33 are respectively threadedly connected to the first threaded section 321 and the second threaded section 322 of the bidirectional screw 32; the locking member 4 comprises a locking bolt, the locking bolt is threadedly connected to the sliding rod 2, and the locking bolt abuts against the bed body 1.

[0026] The medical staff first needs to push the slide bar 2 according to the body type of the to-be-detected person so that the slide bar 2 moves, and the to-be-detected person lies on the bed body 1 with the arms falling between the two clamping plates 33, and then when the slide bar 2 slides to the required position, the locking bolt is rotated to abut against the bed body 1, so that the slide bar 2 cannot slide relative to the bed body 1 again, and then the medical staff slides the bearing block 31 according to the specific position of the arm of the to-be-detected person required to be detected, and the bearing block 31 slides relative to the slide bar 2 (the sliding between the bearing block 31 and the slide bar 2 is damped to prevent the bearing block 31 from sliding relative to the slide bar 2 again during detection), and when the bearing block 31 slides to the required position (for example, the required position is close to the wound of the to-be-detected person but does not contact the wound), the sliding is stopped, and then the medical staff rotates the two-way screw rod 32 to rotate the two-way screw rod 32 relative to the bearing block 31 (a knob can be arranged at the end of the two-way screw rod 32 away from the bed body 1 to facilitate the rotation of the medical staff), and since the two clamping plates 33 are matched with the two-way screw rod 32 through the first threaded segment 321 and the second threaded segment 322, the rotation of the two-way screw rod 32 causes the two clamping plates 33 to approach each other, thereby clamping and fixing the arm, and the upper surface of the bearing block 31 is flush with the upper surface of the bed body 1, which can make the arm placed on the bearing block 31 more comfortable, and the inner sides of the two clamping plates 33 are provided with soft pads, so that the clamping of the clamping plates 33 on the arm is more comfortable, and then the to-be-detected person can be irradiated, and after the to-be-detected person finishes the irradiation work, the medical staff rotates the two-way screw rod 32 again to make the two clamping plates 33 away from each other, and rotates the locking bolt to make the slide bar 2 slide relative to the bed body 1 again, so that the clamping plates 33 are reset and the slide bar 2 is also reset, and the sliding direction of the slide bar 2 relative to the bed body 1 is perpendicular to the sliding direction of the bearing block 31 relative to the slide bar 2, so that the clamping plates 33 on the bearing block 31 can better adjust the position; if the next to-be-detected person with different body type needs to be detected by CT, the medical staff needs to adjust according to the body type of the to-be-detected person, so that each to-be-detected person can be in a more comfortable clamping position during detection.

[0027] In the above technical solution, the present application provides an adjustable CT detection auxiliary fixing device, the medical staff selects the fixing unit according to the required detection position of the to-be-detected person, selects the fixing unit, and then the to-be-detected person first sits on the bed body 1, and then the worker pushes the slide bar 2 to move according to the body type of the to-be-detected person, so that the to-be-detected person lies down and the arms can fall between the clamping pieces 3, and then the slide bar 2 is locked relative to the bed body 1 by the locking piece 4 after moving, and then the clamping piece 3 is slid to clamp and fix the arm, so that the position of the fixing assembly is adjusted to make the to-be-detected person more comfortable during detection.

[0028] The support block 31 is horizontally slidably connected with the support plate 5, the support plate 5 is slidably connected with the bed body 1, the sliding direction of the support block 31 on the support plate 5 is perpendicular to the sliding direction of the support plate 5 on the bed body 1, in the sliding process of the slide rod 2 relative to the bed body 1, the support block 31 can drive the support plate 5 to move, the support plate 5 is used to support the person to be detected, and the situation that the person to be detected is suspended on the bed body 1 is avoided, and in addition, the support block 31 can slide on the support plate 5, so that the position of the clamping piece 3 is not affected by the support plate 5, and the use effect of the device is better.

[0029] The clamping plate 33 close to the bed body 1 is provided with a bandage 331, the other clamping plate 33 is provided with a through hole, the bandage 331 can penetrate through the through hole, and the support block 31 is further provided with a wire locker 311, the clamping piece 3 can clamp and fix the two sides of the arm, however, the clamping piece 3 still has a gap during clamping and fixing the arm, which can cause the movement of the arm, and then residual image occurs during CT irradiation, and the cooperation of the bandage 331 and the wire locker 311 can further tighten the arm, the bandage 331 only needs to limit the arm and does not need to be excessively tightened, and the working principle of the wire locker 311 is that a spherical or similar shaped clamping block is arranged in the wire locker 311, when the rope penetrates through the wire locker 311, the clamping block is clamped on the rope under the action of a spring or other elastic device, when the rope needs to be loosened, the clamping block is retracted by pressing or pulling a specific part, and the locking of the rope is released.
