Description

Technical Field

[0001] The present invention relates to the technical field of medical examination beds, and in particular to an intelligently controlled foldable endoscopic examination bed. Background Art

[0002] Gastroenteroscopy is mainly used to detect diseases of the human digestive tract. It is an effective technical means to detect gastrointestinal diseases in the human body. Gastroenteroscopy uses a 1 cm thick hose with a micro-electronic camera with a cold light source at the end to go deep into the esophagus and stomach from the mouth for esophageal examination, while colonoscopy enters the rectum, colon and cecum from the anus. Doctors can use the display device to check whether there are lesions, and finally take out living tissue cells for testing and relevant treatment according to the condition. During the examination and after the completion of the gastroenteroscopy, it is inconvenient for some elderly, weak and anesthetized patients to move independently. During the examination, they need to be helped up and down the examination bed by several family members and medical staff. After the examination, they need to be pushed onto the bed in a wheelchair. The operation is time-consuming and laborious, which reduces medical efficiency and brings great inconvenience to medical work. In addition, a single patient occupies both the examination bed and the wheelchair. When there are too many patients in the hospital, there will be insufficient equipment.

[0003] The present invention, whose application publication number is CN112220641A, discloses a gynecological examination bed, comprising a leg support plate, a hip support plate and a back support plate, wherein the hip support plate is rotatably connected between the leg support plate and the back support plate through a linkage mechanism, wherein the linkage mechanism comprises two extension components, a lifting component and a translation component, wherein the two extension components are connected to the bottoms of both sides of the hip support plate, the leg support plate and the back support plate are respectively connected to the two ends of the two extension components, the lifting component is connected between the two extension components, the translation component is cooperatively connected with the lifting component, the translation component is used for converting the translation motion into the lifting motion of the lifting component, the lifting component is used for converting the lifting motion into the extension motion of the two extension components, the two extension components are used for realizing the extension motion among the leg support plate, the hip support plate and the back support plate, the structure is very simplified, and the examination bed can be folded when not in use, occupying a small space.

[0047] When the examination is completed, the universal wheel 6 is locked, and the medical staff or family members stand at the position of the pulling rod 11, pull the pulling rod 11 toward the side of the body and push the first support plate 101 upward. At this time, the first support plate and the third support plate 103 adjust the angle at the same time and gradually turn into a push chair. At this time, the pull rope 17 is straightened, and the pull rope 17 pulls the block 1605, and the tooth block on the block 1605 is separated from the rack 1603. The connecting rod 19 pulls the sliding block 1602 to move outward. When the examination bed is adjusted to a suitable angle, the pulling rod 11 is released, and the tooth block on the block 1605 is engaged with the rack 1603.
