[0020] 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.
[0021] like Figure 1-3 As shown, an oral CBCT device includes a scanner body 1 and a driving base 2. The driving base 2 is installed in front of the scanner body 1 through a base. A support table 3 is fixedly installed on the top of the driving base 2. A head support plate 5 is fixedly connected to the rear end of the support table 3.
[0022] The front end of the scanner body 1 is provided with a flat-panel detector 4 that matches the head support plate 5. The top of the head support plate 5 is fixedly connected to a limit plate 6, and a head limit airbag 7 is provided on the inner side of the limit plate 6. The top of the support platform 3 is fixedly connected to slide bars 10 on both sides, and the outer circles of the two groups of slide bars 10 are slidably connected to movable blocks 11 at the front and rear ends, and body limit airbags 12 are provided on the inner sides of several movable blocks 11.
[0023] In this embodiment, an isolation pad 8 is installed at the front position of the top of the support platform 3 through a winding drum. The isolation pad 8 is composed of multiple sections of isolation cloth, and a tear line is provided at the combination. After the isolation pad 8 is laid, it plays a role in isolating the patient and the support platform 3, preventing the patient's sweat or dust on the outer clothes from sticking to the support platform 3, thereby improving the hygiene of use, and the tear line is provided to facilitate tearing.
[0024] In this embodiment, a Velcro surface 9 is provided at the rear position of the top of the support platform 3, and a Velcro hook surface matching the Velcro surface 9 is provided at the bottom end of each isolation pad 8. By pulling out a piece of isolation pad 8 and then fixing the pulled-out isolation pad 8 to the Velcro surface 9, the isolation pad 8 can be simply fixed to prevent it from falling directly.
[0025] In this embodiment, handles are provided at the top of the movable blocks 11, and a locking block is fixedly connected to the lower rear end of the movable block 11. A locking knob 13 is threadedly connected through the upper and lower ends of the locking block. The provided handle makes it easy to push the movable block 11 to slide, and the locking knob 13 makes it easy to fix the position of the movable block 11.
[0026] In this embodiment, the winding drum is movably connected to the support platform 3, and the size of each section of the isolation pad 8 matches the size of the top surface of the support platform 3, so that the position of the winding drum can be adjusted to prevent it from affecting people lying on the support platform 3.
[0027] In this embodiment, the support platform 3 is flush with the top surface of the head support plate 5, and the front end of the flat-panel detector 4 does not contact the support platform 3 and the head support plate 5. Since the front end of the flat-panel detector 4 does not contact the support platform 3 and the head support plate 5, the head support plate 5 and the support platform 3 can be prevented from interfering with the movement of the flat-panel detector 4.
[0028] It should be noted that the utility model is an oral CBCT device. When in use, first, when scanning a patient, because the isolation pad 8 is composed of multiple isolation cloths, and a tear line is provided at the combination, and a Velcro hook surface matching the Velcro velvet surface 9 is provided at the bottom of the isolation pad 8, the medical staff can pull out a piece of isolation pad 8 before scanning, and then fix the pulled isolation pad 8 to the Velcro velvet surface 9;
[0029] After the isolation pad 8 is laid, it plays a role in isolating the patient from the support platform 3, preventing the patient's sweat or dust on the outer clothes from adhering to the support platform 3, and improving the hygiene of use. After that, after the patient lies on the support platform 3, the patient's head can be adjusted to be inside the head limiting airbag 7, and after the patient's head is straightened, the head limiting airbag 7 is inflated to swell, so as to limit the patient's head, thereby preventing the head from turning;
[0030] After the head is fixed, the scanner body 1 can be started as needed, and the flat-panel detector 4 on the scanner body 1 can be rotated to scan the patient's head. After the scanning process is completed, the head limit airbag 7 can be deflated as needed, and the patient can be assisted to stand up. After the patient is away from the support table 3, the used isolation pad 8 can be torn off from the support table 3 as needed, so as to be replaced when another patient is scanned;
[0031] At the same time, during the scanning process, when it is necessary to fix the patient's body, the locking knob 13 can be loosened to release the fixation of the movable block 11. Since the body limiting airbag 12 is installed on the movable block 11, the movable block 11 is slidably installed on both sides of the support platform 3 through the slide rod 10. Therefore, when in use, the movable block 11 can be moved to a suitable position of the patient's body by adjustment, and then the body limiting airbag 12 can be inflated to make it bulge on both sides of the patient's body, so as to fix the unconscious patient's body and prevent the patient's body from swaying back and forth when lying flat.
[0032] 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.
