Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and particularly to a foldable CT examination bed. Background Art
[0002] A CT scanner (Computed Tomography) is a medical imaging device that uses X-rays and computer technology to perform high-resolution tomographic scans of internal organs of the human body. It can generate detailed cross-sectional or specific-layer images, which is of great significance for doctors to diagnose diseases. The existing CT examination bed generally presents a relatively conventional and fixed design pattern. Specifically, its bed body mainly presents in the form of a flat structure. During actual clinical operations, when a patient needs to be examined, usually by translating the bed body, the patient is smoothly sent into the CT scanner to complete the corresponding scanning work. However, although such a design can meet the examination needs of most patients to a certain extent, it has certain limitations, especially in terms of the applicability to specific patient groups. This design is largely optimized for patients with convenient legs and feet. For such patients, they can relatively easily cooperate with the operations of medical staff, move onto the CT bed by themselves or lie on the bed smoothly with the assistance of medical staff, and then complete the entire examination process. However, when encountering patients who are unable to move conveniently due to various reasons, such as fractures in the legs or feet, the disadvantages of this conventional design become prominent. In addition to fractures, there are some other reasons that may cause patients to be unable to move conveniently, such as severe joint diseases, nervous system injuries, etc. For these patients with inconvenient movement, due to the relatively fixed flat structure of this bed body, it cannot be effectively folded or make other adaptive adjustments, which brings troubles to these patients. When they need to undergo a CT examination, it becomes extremely difficult for them to get onto the CT bed smoothly. During this process, patients often need to overcome great physical pain and also feel many inconveniences. They may need to move their bodies with difficulty under the support of medical staff, thus increasing the physical pain of the patients. In view of this, the present invention proposes a foldable CT examination bed to solve the above technical problems. Summary of the Invention
[0003] In view of the deficiencies of the above-mentioned background art, the present invention provides a technical solution for a foldable CT examination bed. The first electric push rod drives the linkage of the second bed board and the third bed board, so that the first bed board, the second bed board and the third bed board are folded into the shape of a chair. At the same time, the driving motor drives the bed body to rotate 90 degrees. After the rotation is completed, the second electric push rod drives the bed body to lower to a height convenient for the patient to sit down, so as to facilitate the patient to sit down. After that, the driving motor and the second electric push rod drive the bed body to perform height and angle reset. After the reset is completed, the first electric push rod starts to spread out the bed body to form a flat bed body, and the bed body drives the patient to move into the inner cavity of the CT machine for scanning operations. The whole process realizes the multi-functional conversion of the CT examination bed from a flat bed body to the shape of a chair convenient for patients with leg fractures to sit down and then back to a flat bed body, significantly improving the convenience and safety of CT examinations for patients with leg injuries, and enhancing the user experience and operation efficiency.

Embodiment
[0017] Please refer to Figure 1-8As shown in the figure, a foldable CT examination bed includes a CT machine body 1 and a bed body 101. The bed body 101 is composed of a first bed board 2, a second bed board 201 and a third bed board 202. A plurality of connecting blocks 203 are fixedly connected to both sides of the first bed board 2. Connecting shafts 204 are fixedly connected to the inner cavities of the connecting blocks 203. The number of the connecting shafts 204 is two. The second bed board 201 and the third bed board 202 are respectively rotatably connected to the surfaces of the connecting shafts 204. Two gears 205 are fixedly connected to the surface of one of the connecting shafts 204 on one side of the second bed board 201. A rack 206 is slidably connected to the inner cavity of the first bed board 2. A first electric push rod 207 is fixedly connected to the inside of the first bed board 2. One end of the output rod of the first electric push rod 207 is fixedly connected to one side of the rack 206. Two connecting plates 208 are fixedly connected to the surfaces of the two connecting shafts 204. A connecting rod 209 is rotatably connected to the inner cavity of the connecting plate 208. The gear 205 and the rack 206 are meshed. An adjusting assembly is arranged at the bottom of the first bed board 2 for adjusting the height and angle of the bed body 101. The adjusting assembly includes a sliding column 3. The sliding column 3 is arranged at the bottom of the first bed board 2. A bearing 301 is fixed in the inner cavity of the sliding column 3. A rotating shaft 302 is fixedly connected to the inner cavity of the bearing 301. One end of the rotating shaft 302 is fixedly connected to the bottom of the first bed board 2. A first driving motor 303 is fixedly connected to the inside of the sliding column 3. One end of the output shaft of the first driving motor 303 is fixedly connected to a synchronous pulley 304. A synchronous belt 305 is jointly sleeved in the inner cavity of the synchronous pulley 304 and the rotating shaft 302. A support column 306 is slidably connected to the surface of the sliding column 3. Two second electric push rods 307 are fixed to the bottom of the inner cavity of the support column 306. One end of the output rod of the second electric push rod 307 is fixedly connected to the bottom of the sliding column 3. A bottom plate 4 is arranged at the bottom of the support column 306. The front and rear surfaces of the support column 306 are slidably connected to the inner cavity of the bottom plate 4. A second driving motor 401 is fixed to one side of the bottom plate 4. One end of the output shaft of the second driving motor 401 is fixed with a threaded rod 402. The inner cavity of the support column 306 is threadedly connected to the surface of the threaded rod 402. An X-ray source 5 and a detector 501 are respectively fixed to one end of the CT machine body 1. Infrared laser emitters 502 are fixed to the front and rear surfaces of the X-ray source 5. An infrared laser receiver 503 is fixed to one side of the second bed board 201. The positions of the infrared laser emitters 502 and the external laser receiver 503 correspond to each other. When the bed body 101 needs to be moved to the vicinity of the CT machine body 1 for position calibration after the bed body 101 moves, medical staff can turn on the two infrared laser emitters 502. At this time, the two infrared laser emitters 502 will emit infrared laser. Then the medical staff can push the bed body 101 to adjust the position of the bed body 101. When the two infrared laser receivers 503 on one side of the second bed board 201 receive the infrared laser, it means that the calibration is completed at this time. The medical staff can stop moving the bed body 101.Push handles 6 are fixedly connected to the front and rear surfaces of the first bed board 2, the second bed board 201, and the third bed board 202. By providing the push handles 6, the push handles 6 are mainly used to facilitate the user to move the bed body 101. At the same time, when the patient turns over on the mattress 601, medical staff can also install a rope through the push handle 6 to fix the patient and prevent the patient from turning over, which may affect the scanning. The push handles 6 are symmetrically designed. A mattress 601 is jointly provided on the tops of the first bed board 2, the second bed board 201, and the third bed board 202. By providing the mattress 601, the mattress 601 is made of a soft material and can be folded along with the folding of the second bed board 201 and the third bed board 202. At the same time, when the patient lies on the mattress 601, it can also improve the comfort of the patient. Bellows folding covers 7 are fixedly connected to the opposite surfaces of the support columns 306 and the bottom plate 4. By providing the bellows folding covers 7, the bellows folding covers 7 can contract according to the movement of the support columns 306, thereby preventing sundries from entering the inner cavity of the bottom plate 4 and affecting the movement formation of the support columns 306. Limiting grooves 701 are provided on the front and rear surfaces of the inner cavity of the support columns 306. By providing the limiting grooves 701, the limiting grooves 701 mainly play a role in guiding and limiting the sliding columns 3. The surface of the sliding column 3 is slidably connected to the inner cavity of the limiting groove 701. A protective shell 8 is fixed to one side of the bottom plate 4 outside the second drive motor 401. By providing the protective shell 8, the protective shell 8 is mainly used to protect the second drive motor 401 and prevent the second drive motor 401 from being stepped on. Self-locking universal wheels 801 are fixed to the four corners of the bottom of the bottom plate 4. By providing the self-locking universal wheels 801, the self-locking universal wheels 801 can be unlocked, and the bed body 101 can be moved according to requirements.,
[0018] In use, when encountering a patient with limited mobility, the first electric push rod 207 can be activated to drive the rack 206 to extend. Since the gear 205 meshes with the rack 206, the movement of the rack 206 will drive the gear 205 to rotate. The rotation of the gear 205 will drive one of the connecting shafts 204 to rotate. The rotation of one of the connecting shafts 204 will further drive the second bed board 201 and two of the connecting plates 208 to rotate. Since two of the connecting plates 208 are connected to the other two connecting plates 208 by a connecting rod 209, at this time, the connecting rod 209 will drive the other two connecting plates 208 and the other connecting shaft 204 to rotate in the reverse direction, thereby driving the third bed board 202 to rotate and fold, so that the first bed board 2, the second bed board 201 and the third bed board 202 form the shape of a chair. At the same time, the mattress 601 will also fold with the second bed board 201 and the third bed board. After the folding is completed, the first drive motor 303 is activated to drive the synchronous pulley 304 to rotate. The rotation of the synchronous pulley 304 will further drive the synchronous belt 305 to rotate, so that the synchronous belt 305 drives the rotating shaft 302 and the bed body 101 to rotate by 90 degrees. Then the second electric push rod 307 is activated to drive the sliding column 3 and the bed body 101 to lower the height, which is convenient for the patient to sit down. When the patient sits on the bed body 101, the second electric push rod 307 and the first drive motor 303 are activated again to reset the height and angle of the bed body 101. After the reset is completed, the first electric push rod 207 is activated again to drive the rack 206 to contract and drive the gear 205, so that the second bed board 201 and the third bed board 202 are unfolded to form a flat bed body 101. At this time, the second drive motor 401 is activated, and the second drive motor 401 will drive the threaded rod 402 to rotate. The rotation of the threaded rod 402 will drive the support column 306 and the bed body 101 to move into the inner cavity of the CT machine body 1. When the patient enters the inner cavity of the CT machine body 1, the CT machine body 1 is activated to drive the X-ray source 5 and the detector 501 in the inner cavity of the CT machine body 1 to rotate at a high speed, so as to perform a CT scan operation on the patient.
