[0002] Dual-energy bone densitometer is a dual-function instrument that can measure bone density and bone age. The conventional dual-energy bone densitometer box structure cannot be used for measuring adults or children at the same time, and it is not convenient to observe from the outside whether the arm is in place inside the box. Therefore, it is necessary to design a dual-energy bone densitometer box structure to solve the above problems. Summary of the invention

[0003] The utility model aims to solve the above problems in the prior art and proposes a dual-energy bone densitometer box structure.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a dual-energy bone densitometer box structure, including an upper box and a lower box, the upper box is provided with a screen, a high-voltage generator, a radiation leakage prevention device and a controller, the lower box is provided with a computer host and a flat-panel detector, and the high-voltage generator, the radiation leakage prevention device and the flat-panel detector are arranged in sequence from top to bottom, characterized in that the lower box is detachably connected with an additional filtering device, the additional filtering device is located between the radiation leakage prevention device and the flat-panel detector, and the side of the lower box is also connected with a lead cuff.

[0005] The lower box body is also provided with lead glass and a camera.

[0006] The lower part of the lower box body is also connected with a base.

[0007] A bottom cover is installed at the lower part of the base, and a lead cover is arranged at the upper part of the high voltage generator.

[0008] Compared with the prior art, the box structure of the dual-energy bone densitometer has the following advantages:

[0009] The additional filtering device in the utility model realizes the dose differentiation between adults and children. The device is simple to install and easy to disassemble. The camera and lead glass can observe from the outside whether the arm is in place inside the box, which is convenient for the operator to take pictures. The lead sleeve has a better protection effect, and the cuff cross-section is close to the arm. When used by children, it can also minimize radiation leakage, and it will not get people's arms stuck like a lead curtain, so it can meet the needs of adults and children at the same time.

[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0013] like Figure 1 As shown, the housing structure of the dual-energy bone densitometer includes an upper housing and a lower housing. The upper housing is provided with a screen 2, a high-voltage generator 3, a radiation-leakage-proof device 5 and a controller 7. The lower housing is provided with a computer host 12 and a flat-panel detector 4. The high-voltage generator 3, the radiation-leakage-proof device 5 and the flat-panel detector 4 are arranged in sequence from top to bottom. In this embodiment, the above structures all adopt the prior art, and the circuit and other connections thereof also adopt the prior art. The lower housing is detachably connected with an additional filtering device 9, which is a piece of pure aluminum that can be conveniently disassembled. Plate, that is, a pure aluminum plate that can be quickly disassembled is added between the radiation source and the flat-panel detector 4, which can conveniently add filtering or not use filtering, and is convenient for adjusting the dosage, so that one device can be used by adults and children at the same time; the additional filtering device 9 is between the anti-leakage radiation device 5 and the flat-panel detector 4, and a lead cuff 11 is also connected to the side of the lower box body. Specifically: the lead cuff 11 is arranged downwardly at an angle, that is, the lead cuff 11 is at a certain angle to the horizontal, so that the lead cuff 11 can naturally droop during use, better contact with the arm, and reduce X-ray leakage.

[0014] Lead glass 10 and a camera 8 are also provided at the lower box body.

[0015] The lower part of the lower box body is also connected to a base 6; a bottom cover 13 is installed at the lower part of the base 6, and a fan is also provided at the lower part of the base 6, and internal cooling and radiation absorption are achieved through the fan and the bottom cover 13; a lead cover 1 is provided on the upper part of the high-voltage generator 3, and the lead cover 1 is used to block the X-rays generated by the high-voltage generator 3 and leaking from the side. At the same time, a fan is also installed there to dissipate heat by the fan; in practice, the box body can be placed as a whole on a configuration trolley or a flat operating table, which is practical, stable and reliable, and occupies a small space.

[0016] In the utility model: the X-rays generated by the high-voltage generator 3 pass through the anti-leakage ray device 5, and then pass through the additional filtering device 9 to be irradiated onto the flat-panel detector 4 for imaging. The examiner extends his arm into the box through the lead cuff 11 to achieve the measurement of bone age and bone density; the operator operates the function through the screen 2, and through the cooperation of the lead glass 10 and the camera 8, it is convenient to observe whether the examiner's arm is in place.
