[0002] Gastroenterology is a tertiary clinical discipline that mainly studies diseases of the esophagus, stomach, small intestine, large intestine, liver, gallbladder and pancreas. Gastroenterology has a wide variety of diseases, a broad range of medical knowledge, and complex and delicate operations. Currently, the main instrument used for gastroenterology examinations is the CT scanner. However, CT scanners generate radiation during the scanning process. While these radiation sources bring convenience to disease diagnosis and treatment, they also pose potential radiation hazards to medical staff, patients and the surrounding environment.

The rotation of the second rotating wheel 210 will drive the first threaded rod 211 to rotate, thereby driving the protective block 212 to move along the first threaded rod 211 toward the third gear 207.

[0021] Specifically, the device has special protection components for different organs of the human body, such as esophagus protection component, right lung protection component, left lung protection component, liver protection component, stomach protection component and intestinal protection component. When performing CT detection, it can accurately expose the corresponding detection cavity according to the specific detection part of the patient, and place other undetected parts in the protection device, which greatly reduces the radiation range of the patient's organs.

[0024] Specifically, by controlling the pull rod 222 to be pulled outward, the fourth gear 213 in the left lung protection component 203 is controlled to separate from the first rack 105, thereby exposing the right lung detection cavity 108, and then the patient's right lung is detected. If the fourth gear 213 in the right lung protection component 202 is controlled to be separated from the first rack 105, the left lung detection cavity 108 is exposed, and the patient's left lung is detected. In this way, the patient's right lung or left lung can be detected by pulling the pull rod 222 outward and the undetected part is placed in the protection device, thereby reducing the radiation range of the patient's organs and reducing the impact of radiation on the patient.

[0025] See also Fig. 9 The liver protection component 204 includes a push-pull rod 224, and one end of the push-pull rod 224 close to the detection chamber 108 is connected to a fourth rack 225, and one end of the fourth rack 225 is connected to a second protection component 226, and the components of the second protection component 226 are the same as the components of the esophageal protection component 201, and the initial position of the fourth rack 225 is separated from the third gear 207 in the second protection component 226, and the third gear 207 in the stomach protection component 205 is staggered with the third gear 207 in the esophageal protection component 201, the fourth gear 213 in the right lung protection component 202, and the fourth gear 213 in the left lung protection component 203, and the components of the stomach protection component 205 are the same as the components of the liver protection component 204.

[0026] Specifically, by pushing the push-pull rod 224 inward, the fourth rack 225 is meshed with the third gear 207 in the second protection component 226, and then the first drive motor is started. In the process of separating the first rack 105 from the third gear 207, the third gear 207 is rotated along the fourth rack 225 and the first rack 105, so that the protection block 212 in the liver protection component 204 completely exposes the patient's liver, and then the protection block in the stomach protection component 205 exposes two-thirds of the patient's stomach. Similarly, if the patient undergoes a stomach test, the same operation as the liver protection component 204 is performed, so that the third gear 207 can be driven to rotate by the first rack 105, so that one-third of the patient's stomach or liver is outside the radiation range, thereby reducing the radiation range of the patient's organs and reducing the impact of radiation on the patient.

[0027] See also Fig.10 The intestinal protection component 206 includes a U-shaped protection block 227, and the end of the U-shaped protection block 227 facing the first rectangular fixed block 106 is connected to the fifth rack 228, the lower end of the fifth rack 228 is meshed with the fifth gear 229, and the end of the fifth gear 229 away from the U-shaped protection block 227 is connected to the first separation component 230, and the end of the U-shaped protection block 227 away from the stomach protection component 205 is connected to the small intestine protection block 231, the lower end of the small intestine protection block 231 is connected to the sixth rack 232, the lower end of the sixth rack 232 is meshed with the sixth gear 233, the end of the sixth gear 233 away from the fifth gear 229 is connected to the rotating group 234, the end of the rotating group 234 away from the fifth gear 229 is connected to the second separation component 235, and the rotating group 234 is composed of three conical gears, so that the rotation direction of the sixth gear 233 is opposite to the rotation direction of the fifth gear 229.

[0028] See also Fig.11 The first separation component 230 includes a seventh gear 236, one end of the seventh gear 236 is connected to the fifth rotating wheel 237, the outer surface of the fifth rotating wheel 237 is connected to the third rotating belt 238, the end of the third rotating belt 238 away from the fifth rotating wheel 237 is sleeved with the sixth rotating wheel 239, the inner cavity of the sixth rotating wheel 239 is connected to the second connecting block 240, the end of the second connecting block 240 away from the sixth rack 232 is connected to the circular pull rod 241, and the components of the second separation component 235 are the same as the components of the first separation component 230, the inner cavity of the fifth rotating wheel 237 is provided with a second connecting groove, the second connecting groove is matched with the second connecting block 240, the center point of the seventh gear 236 in the second separation component 235 and the center point of the seventh gear 236 in the first separation component 230 are on the same straight line, and the circular pull rod 241 is located outside by passing through the U-shaped protective frame 107.

[0029] Specifically, when the patient's large intestine is tested, the circular pull rod 241 in the second separation component 235 is pulled outward, so that the second connecting block 240 in the second separation component 235 is separated from the sixth rotating wheel 239. In this way, when the first rack 105 drives the seventh gear 236 in the first separation component 230 to rotate, it will drive the U-shaped protective block 227 to move toward the CT detector 3 until the patient's large intestine is completely exposed. Then the patient's large intestine is tested. If the patient is tested for the small intestine, the circular pull rod 241 in the first separation component 230 and the circular pull rod 241 in the second separation component 235 are kept in place, so that the first rack 105 drives the seventh gear 236 in the first separation component 230 and the seventh gear 236 in the second separation component 235 to rotate, thereby exposing the patient's small intestine. This can reduce the radiation range of the patient's organs and reduce the impact of radiation on the patient.

[0030] Working principle: first determine which test the patient is to undergo, then let the patient lie on the upper surface of the movable frame 103, and rotate the U-shaped protective frame 107 so that one end of the U-shaped protective frame 107 contacts one end of the movable frame 103. At this time, the circular connecting rod 111 coincides with the fixing groove provided on the surface of one end of the first rectangular fixing block 106, and the circular connecting rod 111 provided in the inner cavity at the other end of the U-shaped protective frame 107 is fixed to the upper surface of the base 101 by magnetic attraction, so that the U-shaped protective frame 107 and the movable frame 103 form a rectangular radiation protection frame; When the U-shaped protection frame 107 and the movable frame 103 form a rectangular radiation protection frame, the first driving motor is started and the fifth rotating belt is driven to rotate, thereby driving a plurality of first circular rotating rods to rotate, thereby driving a plurality of rolling wheels 102 connected to both sides of the upper end of the base 101 to rotate, and then driving the movable frame 103 to move toward the CT detector 3, and the protection component 2, the movable frame 103, the U-shaped protection frame 107, the first rectangular slide groove 104 and the second rectangular slide groove 109 are moved toward the CT detector 3, and the protection component 2 will first contact the first rack 105 during the movement toward the CT detector 3; When the third gear 207 in the esophagus protection component 201 contacts the first rack 105 and rotates along the first rack 105, it drives the first rotating wheel 208 to rotate, thereby driving the first rotating belt 209 to rotate, and then driving the second rotating wheel 210 to rotate. The rotation of the second rotating wheel 210 drives the first threaded rod 211 to rotate, thereby driving the protection block 212 to move along the first threaded rod 211 toward the third gear 207. When the first rack 105 is separated from the third gear 207, the patient's esophagus is located at the CT detector 3. The detection part is set, and the protection block 212 exposes the esophageal detection cavity 108. At this time, if the esophageal detection operation is performed on the patient, the first driving motor is stopped, and the CT detector 3 is started, and then the CT detector 3 is allowed to detect the esophagus of the patient. If the esophageal detection operation is not performed, the first driving motor continues to drive the moving frame 103 to move forward. When the third gear 207 is separated from the first rack 105, the third gear 207 is meshed with the second rack 110, so that the esophageal protection component 201 is reset and then continues to move forward; If the patient's right lung is tested, before starting the first drive motor, the pull rod 222 in the left lung protection component 203 is pulled outward, thereby driving the rectangular magnetic isolation block 221 to move outward until the rectangular magnetic isolation block 221 is separated from the magnetic block 223. At this time, the magnetic block 223 performs a magnetic attraction operation on the first connecting block 214, thereby allowing the first connecting block 214 to move upward along the rectangular sliding groove, thereby driving the fourth gear 213 to move upward until the first connecting block 214 contacts the rectangular blocking block 220, and allowing the first connecting block 214 to separate from the first connecting groove of the third rotating wheel 215. When the first rack 105 is meshed with the fourth gear 213 in the right lung protection component 202, the fourth gear 213 in the left lung protection component 203 is separated from the first rack 105. At this time, as the first rack 105 continues to move forward, the second protection block 219 moves along the second threaded rod 218 toward the outside of the U-shaped protection frame 107, thereby gradually exposing the right lung detection cavity 108. When the first rack 105 is separated from the fourth gear 213, the right lung detection cavity 108 is completely exposed. At this time, the first drive motor is turned off, and the CT detector 3 is started to perform a detection operation on the patient's right lung; If the patient's left lung is tested, the pull rod 222 in the right lung protection component 202 is pulled outward to separate the fourth gear 213 from the first rack 105 in the right lung protection component 202. If the patient's lung is tested, the pull rod 222 remains unchanged, so that the esophagus protection component 201 is operated accordingly and the patient's lung is tested. If the patient undergoes liver detection, before starting the first drive motor, the push-pull rod 224 in the liver protection component 204 is pushed toward the direction of the U-shaped protection frame 107, so that the fourth rack 225 is meshed with the third gear 207 in the second protection component 226, and then the first drive motor is started. In this way, during the separation of the first rack 105 and the third gear 207, the third gear 207 is rotated along the fourth rack 225 and the first rack 105, so that the protection block 212 in the liver protection component 204 completely exposes the patient's liver, and then the protection block in the stomach protection component 205 exposes two-thirds of the patient's stomach. Similarly, if the patient undergoes stomach detection, the same operation as the liver protection component 204 is performed, so that the third gear 207 can be driven to rotate by the first rack 105, so that one-third of the patient's stomach or liver is outside the radiation range, thereby reducing the radiation range of the patient's organs, and then reducing the impact of radiation on the patient; If the patient is undergoing colon examination, before starting the first driving motor, the circular pull rod 241 in the second separation component 235 is pulled outwards, so that the second connection block 240 in the second separation component 235 is separated from the sixth rotating wheel 239. In this way, when the first rack 105 drives the seventh gear 236 in the first separation component 230 to rotate, it will drive the fifth rotating wheel 237 to rotate, thereby driving the third rotating belt 238 to rotate, and then driving the sixth rotating wheel 239 to rotate. As the sixth rotating wheel 239 rotates, it will drive the fifth gear 229 to rotate, thereby driving the fifth rack 228 to move toward the CT detector 3, and then driving the U-shaped protective block 227 to move toward the CT detector 3 until the patient's colon is completely exposed, and then the first driving motor is stopped, and the CT detector 3 is started to detect the patient's colon. If the patient is undergoing small intestine detection, the circular pull rod 241 in the first separation component 230 and the circular pull rod 241 in the second separation component 235 remain in place, so that the first rack 105 drives the seventh gear 236 in the first separation component 230 and the seventh gear 236 in the second separation component 235 to rotate, thereby driving the fifth gear 229 to rotate, and driving the sixth gear 233 to rotate in the opposite direction, and then driving the U-shaped protection block to move toward the CT detector 3, and driving the small intestine protection block 231 to move toward the end away from the CT detector 3, and allowing the patient's small intestine to be completely exposed, then stop the first drive motor, and start the CT detector 3 to detect the patient's small intestine. When the patient's detection is completed, return to the original position, and all operations are ended.
