DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-3 As shown, a chair-type oral CT comprises a chair body 1, a damping adjustment arm 2 is installed at the rear of the chair body 1, a scanner 3 is movably installed at the top of the damping adjustment arm 2, and an adjustment component 4 is arranged at the top of the chair body 1;

[0024] The adjustment component 4 includes two support rods 5, and a movable frame 6 is slidably installed on the outer ring of the two support rods 5. A movable groove is opened inside the movable frame 6, and two limit plates 8 are movably installed on the movable frame 6 through the movable groove. An adjusting threaded rod 7 is threadedly connected to the lower positions on both sides of the two limit plates 8. An airbag cushion 9 is fixedly installed at the center position of the front end of the movable frame 6 through a mounting plate. A memory foam pad 10 is arranged at the front end of the airbag cushion 9, and a protective cloth 11 is connected to the front end of the memory foam pad 10 through Velcro.

[0025] In this embodiment, the outer ring of one of the support rods 5 close to the side of the seat body 1 is provided with an external thread, and the support rod 5 is threadedly connected to two adjusting nuts through the external thread, and the upper and lower opposite surfaces of the two adjusting nuts are respectively fitted with the upper and lower ends of the movable frame 6. By turning the adjusting nuts in turn, the airbag cushion 9 can be adjusted to a position that fits the patient's head.

[0026] In this embodiment, the outer ring of the adjusting threaded rod 7 is provided with two sections of threads of the same length but opposite directions, and an adjusting knob is fixedly connected to one side of the adjusting threaded rod 7. By turning the adjusting threaded rod 7, the two limiting plates 8 can be brought closer to each other, so that the airbag cushion 12 can be brought closer to each other to limit the two sides of the patient's head.

[0027] In this embodiment, the lower inner sides of the two limiting plates 8 are fixedly connected to an airbag cushion 12 via a mounting plate 2, a memory foam pad 13 is provided on the side of the airbag cushion 12 away from the limiting plate 8, and a protective cloth 14 is also connected to the side of the memory foam pad 13 away from the airbag cushion 12 via Velcro. The protective cloth 11 and the protective cloth 14 can be isolated to prevent a large amount of dust or sweat on the patient's head from sticking to the memory foam pad 10 and the airbag cushion 12, and at the same time, it is convenient for replacement to prevent odor after long-term use.

[0028] In this embodiment, inflation valves are provided at the top of airbag cushion 1 9 and airbag cushion 2 12, and anti-pressure grooves are opened at the upper positions on both sides of the memory foam cushion 2 13. After fixation, the patient's ears are in the anti-pressure grooves of the memory foam cushion 2 13, which can prevent pressure on the patient's ears and facilitate improving the comfort of fixation.

[0029] In this embodiment, a strap 15 is connected to the upper front end of the memory foam pad 13 on one side of the seat body 1, and a fixing rod matching the strap 15 is provided on the upper front end of the memory foam pad 13 on the other side of the seat body 1. The strap 15 passes through the fixing rod. By pulling the strap 15, it is convenient to tie the patient's forehead to prevent the head of the patient with poor body control ability from moving forward.

[0030] In this embodiment, a Velcro hook surface is provided at one side of the front end of the strap 15, and a Velcro velvet surface matching the Velcro hook surface is provided at the center of the front end of the strap 15. The Velcro hook surface and the Velcro velvet surface are provided to facilitate tightening and fixing.

[0031] It should be noted that the utility model is a chair-type oral CT. When in use, first, the patient can sit on the chair body 1 and make his back close to the backrest of the chair body 1. When the patient's head is fixed, the height of the airbag cushion 9 can be adjusted in advance according to the height of the patient's head. Because the airbag cushion 9 is installed on the movable frame 6, and the movable frame 6 is slidably installed on the outer ring of the support rod 5 and fixed by the adjusting nut, the height of the movable frame 6 can be adjusted by screwing the adjusting nut in turn. The airbag cushion 9 is moved by the movement of the movable frame 6 to adjust the height, and it can be adjusted to a position that fits the patient's head.

[0032] At the same time, the two limit plates 8 are threadedly mounted on the outer ring of the adjusting threaded rod 7, and the outer ring of the adjusting threaded rod 7 is provided with two sections of external threads of the same length and opposite directions, so that the two limit plates 8 can be brought closer to each other by twisting the adjusting threaded rod 7, thereby driving the two airbag cushions 12 to approach each other to limit the two sides of the patient's head. After adjustment through the above steps, the patient's head can be prevented from rotating during scanning, and then the patient's head can be scanned according to the existing steps. Since the patient's head has been fixed, it is prevented from shaking during CT scan, reducing the impact caused by the shaking of the head;

[0033] When the patient's head is fixed, the strap 15 can be pulled to tie the patient's head according to actual needs to prevent the head of the patient with poor body control ability from moving forward and causing separation. The airbag cushion 1 9 and the airbag cushion 2 12 are inflatable cushions. At the same time, the side of the airbag cushion 1 9 and the airbag cushion 2 12 that contacts the patient's head is provided with a memory foam cushion 2 13 and a memory foam cushion 1 10. After the airbag cushion 1 9 and the airbag cushion 2 12 are inflated, the memory foam cushion 1 10 and the memory foam cushion 2 13 can be pushed to a position that fits the patient's head, and the memory foam cushion 1 10 and the memory foam cushion 2 13 can be deformed to further reduce the gap caused by the fixation, thereby reducing the probability of head shaking.

[0034] At the same time, the memory foam pad 10 and the airbag pad 2 12 are connected with a protective cloth 11 and a protective cloth 2 14 by Velcro. The protective cloth 11 and the protective cloth 2 14 play an isolating role, so that the memory foam pad 10 and the airbag pad 2 12 do not directly contact the patient's head, thereby preventing a large amount of dust or sweat on the patient's head from adhering to the memory foam pad 10 and the airbag pad 2 12. At the same time, it is convenient to replace the protective cloth 11 and the protective cloth 2 14 after use, prevent the generation of odor after long-term use, and improve the hygiene of use.

[0035] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
