| 摘要 |
The invention relates to a device for an examination bed which is adjustable in hight, used particularly for a tomography by scintigraphy. The object of the invention is to enable a large amplitude displacement of the bed along the vertical. It allows to situate the bed, at the maximum position, at a hight with respect to the ground more than twice higher than the low position. An intermediary carriage (14) is intercalated between the patient support (13) and the pedestal (15) of the device. The carriage (14) and the patient support (13) move simultaneously and along the vertical with respect to the pedestal (15) of the device. By using a chain (20) whose extremities (26, 27) are fixed to the pedestal (15) and to the patient support (13), and which passes on top of a pulley (19) fixed to the intermediary carriage (14), the patient support (13) is raised by lifting the intermediary carriage (14).
