[0023] Specifically, the mobile lifting device 2 includes a support frame 21, a motor 22, a screw 23, a fixing assembly 24 and a lifting plate 26.

[0024] By adopting the above technical solution, the bone densitometer can adjust the height of the dual-energy X-ray bone densitometer assembly 1 and other structures through the cooperation of the motor 22 and the screw rod 23 when necessary, so as to better meet the working needs in different situations.

[0025] Specifically, the mobile lifting device 2 further includes a brake wheel 25 , and a plurality of brake wheels 25 are installed below the support frame 21 .

[0026] By adopting the above technical solution, the staff can move the position of the bone densitometer by means of the brake wheel 25 when necessary, thereby reducing the difficulty of moving the bone densitometer and alleviating the labor burden of the staff.

[0027] Specifically, the fixing assembly 24 includes a movable plate 241, an electric telescopic rod 242 and a suction cup 243. The electric telescopic rod 242 is installed at the bottom of the support frame 21, the movable plate 241 is installed below the electric telescopic rod 242, and a plurality of suction cups 243 are installed below the movable plate 241.

[0028] By adopting the above technical solution, the bone densitometer can be assisted in fixing its position when needed through the cooperation of structures such as the suction cup 243 and the electric telescopic rod 242, thereby reducing the possibility of displacement of the bone densitometer due to external friction and the like.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that the sterilization and disinfection device 7 includes a fixed shaft 71, a rotating box 73, a quartz glass plate 74 and a sterilization lamp 75. The fixed shaft 71 is installed on one side of the support frame 21, and the rotating box 73 is installed on the side of the fixed shaft 71 away from the support frame 21 through a bearing. A plurality of sterilization lamps 75 are installed on the inner side of the rotating box 73, and a quartz glass plate 74 is installed on the rotating box 73 and at a position close to the protective component 6 on the side where the plurality of sterilization lamps 75 are located.

[0032] By adopting the above technical solution, the bone densitometer can sterilize and disinfect the dual-energy X-ray bone densitometer component 1 when necessary through the cooperation of the germicidal lamp 75 and the quartz glass plate 74, so as to better meet the working needs in different situations.

[0033] Specifically, the sterilization and disinfection device 7 further includes a friction rubber ring 72 , and the friction rubber ring 72 is installed on a side of the rotating box 73 close to the support frame 21 and at a position outside the fixed shaft 71 .

[0034] By adopting the above technical solution, the bone densitometer can enhance the friction resistance of the rotating box 73 and other structures when rotating through the friction rubber ring 72, thereby reducing the possibility of accidental rotation of the rotating box 73 and other structures.

[0035] When this embodiment is used, when the dual-energy X-ray bone densitometer assembly 1 needs to be sterilized, the medical staff rotates the rotating box 73 in the sterilization and disinfection device 7 to overcome the resistance of the friction rubber ring 72 and rotate around the fixed axis 71 until each sterilization lamp 75 is aligned with the position requiring sterilization and disinfection, and then starts each sterilization lamp 75. The ultraviolet rays emitted by the sterilization lamp 75 pass through the quartz glass plate 74 and contact the dual-energy X-ray bone densitometer assembly 1, thereby sterilizing the dual-energy X-ray bone densitometer assembly 1.

[0036] The structure and principle of the dual-energy X-ray bone densitometer component 1 composed of a dual-energy X-ray bone densitometer and a bone densitometer table, a laser locator 3, an X-ray emission hole 4, a camera 5, a protective component 6 composed of a lead sheet protective outer cover, a first arm placement arc groove, a snap-in groove, a lead sheet protective inner cover and a second arm placement arc groove, and a touch delay switch 8 have been disclosed in a novel dual-energy X-ray bone densitometer disclosed in Chinese patent application No. 201821825082.3. The working principle of the dual-energy X-ray bone densitometer is that when in use, the hand is observed through a camera arranged on one side of the X-ray emission hole. Whether the arm is placed correctly or not, when using the laser locator on the other side of the X-ray emitting hole, first touch the touch delay switch to provide power to the laser locator. The laser locator emits a laser, and the red dot of the laser will indicate the position of the distal end of the radius and ulna for precise positioning. After thirty seconds (at this time, the wrist has been placed properly), the laser power is automatically turned off and the laser locator does not work. The lead protective outer cover and the lead protective inner cover are an integrated molding structure, which effectively reduces the leakage of X-rays emitted by the X-ray emitting hole on the top of the dual-energy X-ray bone densitometer, thereby facilitating the use of patients and medical staff.

[0037] The structure and principle of the sterilization lamp 75 in the utility model have been disclosed in a power transmission mechanism of an electric laparoscopic stapler disclosed in Chinese patent application No. 202122604755.0. Its working principle is to use a lower mercury vapor pressure to emit two ultraviolet rays that are invisible to the naked eye. Its spectral lines mainly have two, one with a wavelength of 253.7 nanometers and the other with a wavelength of 185 nanometers. After the cells absorb the ultraviolet rays, they act on the genetic material in the cells. Through photochemical action, the energy of the ultraviolet rays can cause the genetic material to mutate, causing the bacteria to die immediately or be unable to reproduce, thereby achieving the purpose of sterilization.

[0038] The working principle and use process of the utility model are as follows: when a bone densitometer is needed to be used for testing a patient, the medical staff moves the position of the bone densitometer by moving the brake wheels 25 in the lifting device 2, and then starts the electric telescopic rod 242 in the fixed assembly 24, thereby driving the moving plate 241 to descend until each suction cup 243 is adsorbed on the resting plane, and starts the motor 22, the motor 22 drives the screw rod 23 to rotate, the screw rod 23 is threadedly connected to the lifting plate 26, and the lifting plate 26 is close to the support frame 21, so the screw rod 23 drives the lifting plate 26 and the dual-energy X-ray bone densitometer assembly 1 to move to the required height, and the patient places his arm on the dual-energy X-ray bone densitometer assembly 1 The corresponding position is then controlled to touch the delay switch 8, and the bone density can be detected through the cooperation of the laser locator 3, the X-ray emission hole 4 and the camera 5. The protective component 6 plays a role in reducing X-ray leakage; when the dual-energy X-ray bone densitometer component 1 needs to be sterilized, the medical staff rotates the rotating box 73 in the sterilization and disinfection device 7 to overcome the resistance of the friction rubber ring 72 and rotate around the fixed axis 71 until each sterilization lamp 75 is aligned with the position that needs to be sterilized, and then starts each sterilization lamp 75. The ultraviolet rays emitted by the sterilization lamp 75 pass through the quartz glass plate 74 and contact the dual-energy X-ray bone densitometer component 1, thereby sterilizing the dual-energy X-ray bone densitometer component 1.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
