[0017] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0018] See also Figure 1-7 An adjustable CT detection auxiliary fixing device provided by an embodiment of the present invention includes a bed 1 and fixing units arranged on both sides of the bed 1, each fixing unit includes a slide bar 2, a clamping member 3 and a locking member 4, the slide bar 2 is horizontally slidably connected to the bed 1; the clamping member 3 is horizontally slidably connected to the slide bar 2, the clamping member 3 is used to clamp and fix the arm; the locking member 4 is used to lock and fix the slide bar 2 and the bed 1 relative to each other, specifically, the clamping member 3 includes a bearing block 31, a bidirectional lead screw 32 and Two clamping plates 33 and a bearing block 31 are connected to the slide rod 2 in an axially sliding manner along the slide rod 2; the bidirectional screw is rotatably connected to the bearing block 31, and the bidirectional screw 32 includes a first threaded segment 321 and a second threaded segment 322; the two clamping plates 33 are slidably connected to the bearing block 31, and the two clamping plates 33 are respectively threadedly connected to the first threaded segment 321 and the second threaded segment 322 of the bidirectional screw 32, and the locking member 4 includes a locking bolt, which is threadedly connected to the slide rod 2, and the locking bolt abuts against the bed body 1.

[0019] The medical staff first needs to push the slide bar 2 according to the body shape of the person to be tested so that the slide bar 2 moves. The person to be tested lies flat on the bed 1 so that his arms can fall between the two clamping plates 33. When the slide bar 2 slides to the required position, the locking bolt is rotated so that the locking bolt abuts against the bed 1, so that the slide bar 2 cannot slide relative to the bed 1 again. Then the medical staff slides the bearing block 31 according to the specific position of the arm to be tested, and the bearing block 31 slides relative to the slide bar 2 (the sliding between the bearing block 31 and the slide bar 2 has a resistance). The first threaded section 321 and the second threaded section 322 are used to cooperate with the two-way lead screw 32. The rotation of the two-way screw 32 will make the two clamping plates 33 approach each other, thereby clamping and fixing the arm. 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. The inner sides of the two clamping plates 33 are provided with cushions to make the clamping plates 33 clamp the arm more comfortable. Then the patient can be irradiated. After the patient has finished the irradiation, the medical staff rotates the two-way screw 32 again to make the two clamping plates 33 move away from each other, and rotates the locking bolt to make the slide The rod 2 can slide relative to the bed body 1 again to reset the clamping plate 33 and also reset the slide bar 2. The sliding direction of the slide bar 2 relative to the bed body 1 is perpendicular to the sliding direction of the support block 31 relative to the slide bar 2, so that the clamping plate 33 on the support block 31 can be better adjusted in position; if the next person to be tested with a different body shape needs to undergo CT examination, the medical staff needs to adjust according to the body shape of the person to be tested, so that the fixed components of each person to be tested can be in a more comfortable clamping position (for the person to be tested) during the examination.

[0020] In the above technical scheme, the present invention provides an adjustable CT detection auxiliary fixing device. The medical staff selects the fixing unit according to the required detection part of the person to be detected. After selecting the fixing unit, the person to be detected first sits on the bed 1, and then the worker pushes the slide bar 2 to move according to the body shape of the person to be detected, so that the arms of the person to be detected can fall between the clamps 3 after lying flat. After the slide bar 2 moves and receives, the slide bar 2 is locked relative to the bed 1 through the locking member 4, and then the sliding clamp 3 is enabled to clamp and fix the arm, thereby realizing the position adjustment of the fixing component and making the person to be detected more comfortable.

[0021] Among them, a support plate 5 is horizontally slidably connected to the supporting block 31, and the support plate 5 is slidably connected to the bed body 1. The sliding direction of the supporting block 31 on the support plate 5 is perpendicular to the sliding direction of the support plate 5 on the bed body 1. During the sliding process of the slide bar 2 relative to the bed body 1, the supporting block 31 can drive the support plate 5 to move, and the support for the person to be tested is achieved through the support plate 5, which avoids the situation where the person to be tested lies on the bed body 1 and is suspended. In addition, the supporting block 31 can slide on the support plate 5, so that the support plate 5 does not affect the position change of the clamping member 3, so that the device can be used more effectively.

[0022] Among them, a strap 331 is provided on the clamping plate 33 close to one side of the bed body 1, and a through hole is opened on the other clamping plate 33, and the strap 331 can pass through the through hole. A wire locker 311 is also provided on the supporting block 31, and the clamping member 3 can clamp and fix the two sides of the arm. However, there is still a gap in the process of the clamping member 3 clamping and fixing the arm, which may cause the movement of the arm, and then cause afterimage during CT irradiation. The arm can be further tightened by the cooperation of the strap 331 and the wire locker 311. The strap 331 only needs to limit the arm without excessive tightening. The working principle of the wire locker 311 is as follows: there is a spherical or similar shaped card block inside. When the rope passes through the wire locker 311, the card block will clamp the rope under the action of a spring or other elastic device. When the rope needs to be loosened, the card block is retracted by pressing or pulling a specific component to release the lock on the rope.

[0023] The bidirectional lead screw 32 is made of plastic. If metal or other materials are used within the irradiation range, it is easy to cause a virtual shadow of the CT irradiation and affect the irradiation. However, the plastic material will not affect the irradiation process. The screw or locking bolt is also made of plastic.

[0024] In another embodiment provided by the present invention, the locking member 4 includes a screw rod, which is rotatably connected to the bed body 1, and the screw rod is threadedly connected to the slide rod 2 through a thread. A knob is fixedly connected to the end of the screw rod away from the bed body 1. The medical staff drives the screw to rotate by turning the knob. During the rotation of the screw relative to the bed body 1, the screw rod cooperates with the slide rod 2 through the thread, and the slide rod 2 is slidably connected to the bed body 1. Therefore, the rotating screw rod can make the slide rod 2 move relative to the bed body 1. In addition, if the screw rod is not rotated, the slide rod 2 will be fixed in a certain position and cannot move, achieving a locking effect.

[0025] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
