Each set of sliding assemblies includes a sliding rod 116 and a limiting block 117. Each set of mounting assemblies includes an L-shaped plate 118 and two bolts 119. The aforementioned solution solves the problem in the prior art where, when the patient's head is fixed on the headrest for examination, their neck is in a suspended state, which easily leads to neck pain.

[0021] In this specific embodiment, two clamping pads 102 are symmetrically arranged inside the support platform 101, and each clamping pad 102 is provided with a cavity 103. Two pieces of sound-insulating cotton 104 are respectively disposed in the corresponding cavities 103. The lead screw 105 passes through the support platform 101 and is threadedly engaged with the support platform 101. One end of the lead screw 105 is rotatably connected to the head cover 107, and the other end of the lead screw 105 is fixedly connected to the round button 106. The buffer pad 108 is connected to the head cover 107. The head cover 107 is fixedly connected and located inside the head cover 107. The lifting assembly is disposed on one side of the support platform 101, the lifting plate 109 is disposed above the lifting assembly, the neck pillow 111 is disposed on the upper surface of the lifting plate 109, two sets of sliding assemblies are symmetrically disposed on the lower surface of the neck pillow 111, and two sets of mounting assemblies are symmetrically disposed on the bottom surface of the support platform 101. In actual use, the support platform 101 is fixed to the CT examination table by the two sets of mounting assemblies. Then, the patient's head is placed on the upper surface of the support platform 101. The knob 106 is then rotated, which drives the lead screw 105 to rotate. The lead screw 105 moves the head cover 107 until it touches the top of the patient's head. The cushioning pad 108 reduces the pressure of the head cover 107 on the patient. Then, two hydraulic cylinders 120 drive two clamping pads 102 to move relative to each other, thereby clamping the sides of the patient's head and placing the patient's ears in the cavity 103. The sound insulation cotton 104 reduces noise. Then, the neck pillow 111 is pulled, which drives two sets of sliding components to move on the lifting plate 109, thereby moving the neck pillow 111 to the middle position of the patient's neck. Then, the lifting components drive the lifting plate 109 to move upward, which in turn drives the neck pillow 111 to move upward until the neck pillow 111 fits against the patient's neck, thereby supporting the patient's neck.

[0022] The movable component is located on one side of the support platform 101. Two movable plates 112 are threadedly engaged with the movable component. One end of each of the two connecting rods 113 is hinged to one of the two movable plates 112, and the other end of each of the two connecting rods 113 is hinged to the lifting plate 109. In actual use, the movable component drives the two movable plates 112 to move relative to each other. The two movable plates 112 drive one end of each of the two connecting rods 113 to move relative to each other, and the other end of each of the two connecting rods 113 drives the lifting plate 109 to move upward.

[0023] Secondly, the frame 114 is fixedly connected to the support platform 101 and is located on one side of the support platform 101. The bidirectional threaded rod 115 passes through the two movable plates 112 respectively and is threadedly engaged with the two movable plates 112 respectively. The two ends of the bidirectional threaded rod 115 are rotatably connected to the frame 114 respectively. In actual use, the motor 121 drives the bidirectional threaded rod 115 to rotate, so that the two movable plates 112 move relative to each other.

[0024] Meanwhile, the lifting plate 109 has a rectangular groove 110, and the slide rod 116 passes through the rectangular groove 110 and is slidably connected to the lifting plate 109. One end of the slide rod 116 is fixedly connected to the neck pillow 111, and the other end of the slide rod 116 is fixedly connected to the limiting block 117. In actual use, pulling the neck pillow 111 causes the neck pillow 111 to slide the slide rod 116 in the rectangular groove 110, thereby adjusting the position of the neck pillow 111. The limiting block 117 limits the slide rod 116.

[0025] In addition, the L-shaped plate 118 is fixedly connected to the support table 101 and is located on the bottom surface of the support table 101. Two bolts 119 pass through the L-shaped plate 118 respectively. In actual use, the L-shaped plate 118 is fixed to the CT examination bed by the bolts 119, thereby installing the support table 101.

[0026] In this embodiment of the CT examination headrest, during actual use, the L-shaped plate 118 is fixed to the CT examination bed by the bolt 119, thereby installing the support platform 101. The patient's head is then placed on the upper surface of the support platform 101. The knob 106 is then rotated, causing the lead screw 105 to rotate. The lead screw 105 moves the head cover 107 until it abuts against the top of the patient's head. The cushioning pad 108 reduces the pressure of the head cover 107 on the patient. Two hydraulic cylinders 120 then move the two clamping pads 102 relative to each other, clamping the sides of the patient's head and positioning the patient's ears within the cavity 103. The sound-absorbing cotton 104 reduces noise. Then, the neck... The neck pillow 111 drives the slide rod 116 to slide within the rectangular groove 110, thereby moving the neck pillow 111 to the middle position of the patient's neck. Then, the motor 121 drives the bidirectional threaded rod 115 to rotate, causing the two moving plates 112 to move relative to each other. The two moving plates 112 respectively drive one end of the two connecting rods 113 to move relative to each other, and the other end of the two connecting rods 113 respectively drive the lifting plate 109 to move upward. The lifting plate 109 drives the neck pillow 111 to move upward until the neck pillow 111 fits against the patient's neck, thereby supporting the patient's neck. This method can effectively solve the problem in the prior art where the patient's neck is suspended in the air when the patient's head is fixed on the headrest for examination, which easily leads to neck pain.
