[0002] Computed tomography (CT) of the chest and abdomen is a common and important method in medical diagnosis and treatment. This examination can provide detailed internal images to help doctors make accurate diagnoses.

[0003] However, during a CT scan, when the target scanning area is the abdomen and pelvis, the arms are usually placed on both sides of the legs; when the target scanning area is the chest (especially the lungs), the patient is usually required to put the backs of both hands under the head. In existing CT scanning equipment, there is often a lack of corresponding limb positioning structures. Especially for patients who are rushed to the hospital in an emergency, their physical condition may not be ideal and it is difficult for them to maintain a certain posture for a long time. This requires medical staff to spend more energy to coordinate and adjust the patient's posture, increasing their work pressure. When the patient cannot maintain a stable limb position, it will affect the quality and accuracy of the scan, and thus affect the doctor's diagnosis results. Utility Model Content

[0004] The utility model aims to solve one of the technical problems in the related art at least to a certain extent.

[0027] The head placement seat 2 is installed on the supporting base plate 1 , and the rotating rod 3 is symmetrically rotatably connected to the bottom of both ends of the head placement seat 2 .

[0028] It should be noted that a mounting groove is provided below the end of the support base plate 1 described in this embodiment, and both the head placement seat 2 and the extended edge of the support base plate 1 are arc-shaped structures to avoid scratches on the body.

[0029] As a possible situation, through grooves are provided at the bottom of both sides of the head placement seat 2, and the patient's hands can be inserted into the through grooves, so that the patient's hands can be placed under the head, which is conducive to CT scanning of the chest and lungs.

[0030] It should be understood that the top of the head rest seat 2 is installed with soft materials, such as foam materials and memory foam.

[0031] The end of the rotating arm 4 is rotatably connected to the rotating rod 3 , and the guide groove 5 is opened on the rotating arm 4 .

[0032] Furthermore, if Figure 1 As shown, a damping pad is installed at the junction of the end of the rotating arm 4 and the rotating rod 3.

[0033] As a possible situation, a plurality of limit holes are provided in a circle around the rotating rod 3 at the end of the rotating arm 4, which are not marked in the figure, and a positioning bolt is installed on the upper surface of the supporting base plate 1, which is not marked in the figure. Through the positioning bolt and the plurality of limit holes, the rotating angle of the rotating arm 4 can be conveniently adjusted to adapt to different patient postures.

[0034] The limb positioning mechanism 6 may include a guide rod 61 , a sliding base plate 62 , a fixed sleeve plate 63 and a positioning assembly 64 .

[0035] The guide rod 61 is slidably installed in the guide groove 5 , and the sliding base plate 62 is slidably installed on the rotating arm 4 by being fixedly connected to the guide rod 61 .

[0036] It should be noted that the outer wall of the guide rod 61 described in this embodiment is symmetrically fixedly connected with a guide block, and the inner walls of the guide groove 5 are provided with snap-in grooves matching the guide blocks, thereby ensuring that the sliding of the guide rod 61 in the guide groove 5 is more stable.

[0037] The fixed sleeve plate 63 is fixedly connected to the sliding bottom plate 62 , and the positioning assembly 64 is installed on the fixed sleeve plate 63 .

[0038] Furthermore, if Figure 1 As shown, limiting bolts 631 are symmetrically installed at both ends of the outer wall of the fixed sleeve plate 63 , and limiting grooves matching the limiting bolts 631 are symmetrically opened on the upper surface of the rotating arm 4 .

[0039] It should be noted that the fixed sleeve 63 described in this embodiment is a U-shaped structure as a whole, with protrusions provided at both ends of the fixed sleeve 63, the middle end of the fixed sleeve 63 is an arc-shaped structure, and an anti-slip pad is installed on the inner bottom of the limiting groove. When the end of the limiting bolt 631 contacts the anti-slip pad, the friction force increases to ensure that the sliding base plate 62 is not easy to move.

[0040] The auxiliary assembly 7 is mounted on the end of the rotating arm 4 .

[0041] It should be noted that the auxiliary component 7 described in this embodiment is installed on the rotating arm 4 and is away from one end of the rotating rod 3 .

[0042] Specifically, when a patient needs to undergo a CT scan in the radiology department, the patient must first be placed on the bed, and then the arm must be placed in a corresponding position according to the body position that the patient needs to scan. When taking chest and lung images, through grooves are provided at the bottom of both sides of the head placement seat 2, so that the patient's hands can be inserted into the through grooves, thereby allowing the patient's hands to be placed under the head, which is beneficial for CT scanning of the chest and lungs. When performing abdominal and pelvic scans, the rotation angle of the rotating arm 4 can be adjusted to adapt to the body shapes of different patients, and then the sliding base plate 62 is adjusted to a suitable position on the rotating arm 4 through the limiting bolt 631, and then the patient's arm is passed through the fixed sleeve 63. After passing through, the position of the arm can be fixed by the positioning assembly 64. Therefore, for patients whose physical condition is not ideal and who find it difficult to maintain a certain posture for a long time, medical staff do not need to spend more energy to coordinate and adjust the patient's posture, thereby reducing their work pressure.

[0043] At the same time, after the upper limb positioning is completed, the auxiliary component 7 can be used to assist in fixing the position of the leg, thereby further improving the quality and accuracy of the CT scan.

[0044] In one embodiment of the present invention, Figure 1-Figure 4 As shown, the positioning assembly 64 may include an adjusting screw 641, a lower pressure sleeve 642 and a lower pressure pad 643, wherein the adjusting screw 641 passes through the upper surface of the fixed sleeve plate 63 and is rotatably connected to the outer wall of the lower pressure sleeve 642; the lower pressure pad 643 is installed on the inner wall of the lower pressure sleeve 642.

[0045] It should be noted that the lower pressure sleeve 642 and the lower pressure pad 643 described in this embodiment are both arc-shaped structures, and the lower pressure sleeve 642 is an elastic structure.

[0046] Specifically, after the arm passes through the fixed sleeve 63, since the adjusting screw rod 641 passes through the upper surface of the fixed sleeve 63 and is rotatably connected to the outer wall of the lower pressure sleeve 642, the lower pressure pad 643 is installed on the inner wall of the lower pressure sleeve 642. Therefore, by rotating the adjusting screw rod 641, the lower pressure sleeve 642 can be driven to be pressed down, and then the position of the arm is fixed by the lower pressure pad 643. Since the lower pressure pad 643 is a soft structure, the comfort of the patient can be guaranteed.

[0047] In one embodiment of the present invention, Figure 1-Figure 4 As shown, the auxiliary component 7 may include a positioning screw 71 and a positioning sleeve 72, wherein the end of the positioning screw 71 passes through the rotating arm 4 and is rotatably connected to the outer wall of the positioning sleeve 72; and a soft rubber pad is installed on the inner wall of the positioning sleeve 72.

[0048] It should be noted that the positioning sleeve 72 described in this embodiment is an arc-shaped structure, which can ensure that the inner wall of the positioning sleeve 72 fits the patient's legs better.

[0049] Specifically, after the upper limb positioning is completed, because the end of the positioning screw rod 71 passes through the rotating arm 4 and is rotatably connected to the outer wall of the positioning sleeve plate 72; the inner wall of the positioning sleeve plate 72 is installed with a soft rubber pad, so by rotating the positioning screw rod 71, the positioning sleeve plate 72 can be driven to limit the patient's legs, thereby preventing the patient's legs from moving during the CT scan and affecting the accuracy of the scan.

[0050] In summary, the CT examination positioning auxiliary device of the embodiment of the utility model, when performing chest and lung imaging, because through grooves are provided on the bottom of both sides of the head placement seat, the patient's hands can be placed under the head. When performing abdominal and pelvic scanning, the position of the arms can be fixed by the positioning component. Therefore, for patients whose physical conditions are not ideal and who have difficulty maintaining a certain posture for a long time, medical staff do not need to spend more energy to coordinate and adjust the patient's posture, thereby reducing their work pressure.
