Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and more specifically, to a measuring device for detecting the bed moving accuracy of a medical CT machine. Background Art

[0002] The medical CT machine uses a computer to control the bed moving system. Whether the length of the mobile examination bed and the instruction of moving the examination bed given by the computer accurately match or not directly affects the precise positioning of the patient's lesion. The current method for detecting the accuracy of bed moving is to place a ruler with an accuracy of 1mm and a length of not less than 30cm next to the examination bed, ensure that the ruler is parallel to the examination bed, make a pointer on the examination bed that can indicate the ruler scale, and then give a bed moving instruction. For example, a measuring device for detecting the accuracy of medical CT machine bed moving disclosed in the prior art publication number (CN210773787U) uses a scale fixed on the CT machine as the main scale, and a vernier scale is moved to the edge of the scale to align. As the examination bed moves, the vernier scale is displaced relative to the scale. Finally, the final displacement distance is obtained by reading the two scales, which is similar to the principle of a vernier caliper and can improve the accuracy. The measured result is compared with the bed moving instruction to obtain the bed moving accuracy.

[0003] When the above device is in use, it has a simple structure, a wide range of applications, strong versatility, and convenient measurement. It can effectively improve the measurement accuracy of the bed moving accuracy and prevent the influence of subjective factors during manual measurement. However, after the installation is completed, the telescopic rod and the universal joint are prone to shaking when the bed moves, which can easily affect the accuracy of the bed movement measurement.
