Technical Field

[0001] The utility model relates to the technical field of bone densitometers, in particular to a shielding door component of a bone densitometer. Background Art

[0002] Bone densitometer is an instrument for measuring the mineral density of human bones. It plays an important role in judging and studying bone physiology, pathology and the degree of human aging, as well as diagnosing various diseases throughout the body. Currently, the international gold standard for measuring bone density is through X-ray measurement.

[0003] X-rays measure bone density with good imaging effects and high accuracy, but excessive exposure to ionizing radiation can harm human health. In order to ensure the accuracy of the results, X-ray bone densitometers need to be regularly exposed and calibrated in combination with phantoms. During exposure, X-rays are output, exposing medical staff to unnecessary radiation. In order to reduce the impact of radiation on medical staff, bone densitometers can only be calibrated in a shielded room, which is cumbersome and limited in space. Utility Model Content

[0025] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model is further described in detail below in conjunction with the accompanying drawings:

[0027] A shielding door assembly 7 of a bone densitometer, such as Figure 1-Figure 4 , including a revolving door 76 and an outer door frame 71 , wherein the revolving door 76 is rotatably mounted on one side of the outer door frame 71 .

[0028] like Figure 2 During the detection, the revolving door is rotated to expose the opening on the outer door frame 71; Figure 1 When the device is stopped or the calibration process is stopped, the opening on the outer door frame 71 is closed by rotating the revolving door in the opposite direction. The operation is simple and convenient, and the medical staff are less exposed to additional X-ray radiation, and the bone densitometer needs to be moved to a shielded room during the calibration process.

[0029] The outer door frame 71 is installed on the first opening 65 of the outer box 6 of the bone densitometer.
