Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bone density testing technology, specifically relating to a bone density testing instrument. Background Technology
[0002] A bone mineral density (BMD) analyzer is a medical device commonly used to detect bone density. It assesses bone health and helps in the early detection of bone diseases such as osteoporosis. The principle of BMD testing is to detect the mineral content in bones using X-rays. Commonly used equipment includes dual-energy X-ray absorptiometry (DXA or DEXA) and quantitative computed tomography (QCT).
[0003] Currently, bone densitometer X-ray equipment uses lead sheeting for radiation shielding, and then uses a frame to fix the equipment. Because lead sheeting is a flexible material, directly covering the X-ray source before assembly makes it difficult to guarantee the assembly accuracy of the radiation emitting and receiving ends. Furthermore, the lead sheeting requires repeated covering and disassembly during equipment assembly and maintenance, which can easily cause damage and compromise consistency.
[0004] To address the aforementioned issues, this application proposes a bone mineral density testing device. Utility Model Content
[0005] To address the aforementioned problems in the existing technology, this utility model provides a bone density testing device that avoids the impact of disassembling and assembling the X-ray source tube on the lead sheet protection effect.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a bone density testing device, comprising three parts: an image module, a control module, and an interface module. The image module includes a "C"-shaped bracket, which includes two symmetrical first fixed brackets and a bracket connecting plate connecting them. An mounting plate for mounting a radiation source tube is fixed at the upper end between the two first fixed brackets via a second fixed bracket. A radiation receiver is mounted at the bottom of the bracket via a fixed plate. The radiation receiver and the radiation source tube are arranged vertically opposite each other in the bracket. A protective cover is provided on the bracket, located outside the radiation source tube and cooperating with the mounting plate. The protective cover is detachably connected to the mounting plate. A lead sheet is attached to the inner surface of the protective cover to form a protective layer outside the radiation source tube, and the lead sheet does not contact the radiation source tube.
[0007] As a preferred technical solution of this utility model, the protective cover includes a shielding cover connected to the mounting plate and in the shape of a "U" and end caps set at the front and rear ends of the shielding cover. The lead sheet pasted inside the protective cover achieves non-contact protection of the X-ray source tube.
[0008] As a preferred technical solution of this utility model, the control module includes a base that is vertically arranged and fixed to the bracket, and a base is vertically provided at the bottom of the base to form a support at the bottom of the ray receiver.
[0009] As a preferred embodiment of this utility model, the base has an inner cavity for installing the controller on its rear side, a switch is provided on one side of the base, and the interface module is installed at the lower rear end of the base.
[0010] As a preferred embodiment of this utility model, the second fixing bracket is provided with at least two screws that are fixed to the mounting plate to press the X-ray source tube tightly, and the X-ray source tube is arranged horizontally.
[0011] As a preferred embodiment of this utility model, the top of the base is formed with an extension that covers the part of the bottom of the shield that is not connected to the mounting plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] The lead sheet used to protect the X-ray source tube is pasted on the inside of the protective cover. The lead sheet has no direct contact with the X-ray source tube. During equipment assembly and maintenance, it is not necessary to repeatedly cover and remove the lead sheet, which ensures the consistency and integrity of the protective lead sheet. Since the X-ray source tube is assembled with the X-ray receiver as a single unit without lead sheet, the assembly accuracy and integrity are well guaranteed.
[0014] The image module, control module, and interface module of the equipment are assembled and fixed independently and shielded. After being assembled separately, they are combined into a whole machine. This not only ensures the assembly accuracy of each part, but also ensures that the shielding protection is in place and minimizes mutual interference, which greatly improves the flexibility of the overall machine structure assembly and the efficiency of shielding protection.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example: Please refer to Figure 1-4 This utility model provides the following technical solution: A bone density testing device, consisting of three parts: an image module 1, a control module 2, and an interface module 3. The image module 1 includes a "C"-shaped bracket, which includes two symmetrical first fixed brackets 13 and a bracket connecting plate 14 connecting them. An mounting plate 15 is fixed at the upper end between the two first fixed brackets 13, and a radiation source tube 16 is installed through a second fixed bracket 17. A radiation receiver 11 is installed at the bottom of the bracket through a fixed plate 12. The radiation receiver 11 and the radiation source tube 16 are arranged vertically opposite each other in the bracket. A protective cover is provided on the bracket, located outside the radiation source tube 16 and cooperating with the mounting plate 15. The protective cover is detachably connected to the mounting plate 15. A lead sheet is attached to the inner surface of the protective cover to form a protective layer outside the radiation source tube 16. The lead sheet does not contact the radiation source tube 16. The design of the lead sheet not contacting the radiation source tube affects the lead sheet when the radiation source tube 16 is disassembled and assembled, while the lead sheet can also ensure effective protection.
[0023] Specifically, the protective cover includes a U-shaped shielding cover 18 connected to the mounting plate 15 and end caps 19 located at the front and rear ends of the shielding cover 18. The U-shaped structure of the protective cover and the design of the end caps, combined with the protective function of the lead sheet, can effectively prevent radiation leakage from the X-ray source tube 16 to the outside, ensuring the safety of the operators. The lead sheet pasted inside the protective cover provides non-contact protection for the X-ray source tube 16.
[0024] Specifically, the control module 2 includes a vertically arranged base 21 fixed to the bracket, and a base 22 is vertically provided at the bottom of the base 21 to form a support at the bottom of the radiation receiver 11. The base 22 further enhances the structural stability of the radiation receiver 11.
[0025] Specifically, the base 21 has an inner cavity 23 formed on the rear side for mounting the controller 24, and a switch 25 is provided on one side of the base 21. The design of setting the controller 24 and the side switch 25 in the inner cavity 23 on the rear side of the base makes operation more convenient, easier to control and maintain. The interface module 3 is installed at the lower rear side of the base 21. The installation position of the interface module 3 is reasonable, making it easy to connect to external devices and connect to the controller and switch, providing a better user experience and compatibility.
[0026] Specifically, the second fixed bracket 17 has at least two screws that are fixed to the mounting plate 15 to press the X-ray source tube 16 tightly. This stable installation method effectively prevents any displacement of the X-ray source during use, thereby ensuring the accuracy and consistency of the measurement, and is easy to disassemble. The X-ray source tube 16 is set in a horizontal position. The horizontal design of the X-ray source tube makes the equipment more compact, which is conducive to space optimization and equipment stability improvement.
[0027] Specifically, the base 21 has an extension on its top that covers the part of the bottom of the shield 18 that is not connected to the mounting plate 15. In this embodiment, the extension on the top of the base can cover the part of the bottom of the shield that is not connected to the mounting plate, which further improves the radiation protection effect and ensures that the operator is not affected by unnecessary radiation.
[0028] Working principle and usage process of this utility model:
[0029] Image module 1 assembly process: The first fixed bracket 13 and the mounting plate 15 are connected between the two first fixed brackets 13 to form a frame. The X-ray receiver 11 is fixed to the bottom of the assembled frame through the fixed plate 12. The X-ray source tube 16 is fixedly installed on the mounting plate 15 through the second fixed bracket 17. Protective lead sheet is evenly and smoothly pasted on the inside of the shielding cover 18 and the two end caps 19. The shielding cover 18 is fixed on the upper end of the mounting plate 15 to cover the X-ray source tube 16. The end caps 19 are fixed at both ends so that the pasted lead sheet wraps around the X-ray source tube 16.
[0030] Assembly process of control module 2: The base 21 and the base 22 are combined to form a bracket, the rear end of the bracket forms an inner cavity 23, the controller 24 is installed inside the inner cavity 23, and the switch 25 is installed on the side of the bracket.
[0031] Final assembly: Image module 1, control module 2, and interface module 3 are assembled together with bolts as shown in the attached diagram.
[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
