Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to an ultrasonic bone densitometer with a function of matching the body position of an operator. Background Art

[0002] Ultrasonic bone densitometers use ultrasonic waves to pass through water or a coupling agent and through the tissue being tested to measure a group of bone quality-related parameters, such as SOS (ultrasonic sound velocity), BUA (ultrasonic frequency attenuation), and BQI (bone quality index) of the human calcaneus, hip bone, tibia, and phalanges. They calculate and reflect the human bone mass value, thereby diagnosing the bone condition of the subject. Ultrasonic bone densitometers are easy to detect and do not cause radiation damage. They are currently the only instrument that can be widely used for surveys, reexaminations, dynamic observation of bone density changes, and timely prediction of the risk of complications.

However, in actual use, there are the following deficiencies: when the ultrasonic bone densitometer is used, the height of the ultrasonic bone densitometer is mostly fixed, and the computer monitor is mostly fixed, while the height of the operator is mostly different. The height of the bone densitometer is not easy to match the height of the operator, and the distance between the operator and the computer monitor is not easy to adaptably adjust, which is inconvenient for the operator to use.

[0004] Therefore, an ultrasonic bone densitometer with the function of matching the operator's body position is needed to solve the problems in the prior art that the height of the bone densitometer is not easy to match the operator's height and the distance between the operator and the computer monitor is not easy to adaptably adjust.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] See also Figures 1-4 The present invention provides an ultrasonic bone densitometer with a function of matching the operator's body position, comprising a base 1, a support plate 2 fixedly connected to one end of the top surface of the base 1, a lifting mechanism 3 provided inside the support plate 2, the support plate 2 connected to a placement table 4 via the lifting mechanism 3, an adjustment component 5 provided at one end of the top surface of the placement table 4, and a display screen 6 installed on the placement table 4 via the adjustment component 5;

[0023] The lifting mechanism 3 includes a cavity 31, which is opened inside the support plate 2. Slide grooves 32 are opened on both side walls of the cavity 31. A threaded rod 33 is rotatably connected between the center of the top and bottom surfaces of the cavity 31. A worm gear 34 is tightly sleeved on the outer surface of the bottom of the threaded rod 33. A worm 35 meshing with the worm gear 34 is rotatably connected between the two end walls of the cavity 31. A lifting plate 36 is threadedly connected to the outer surface of the threaded rod 33. Sliders 37 cooperating with the slide grooves 32 are fixedly connected to the outer walls of both sides of the lifting plate 36. Two support columns 38 distributed in parallel are fixedly connected to the top surface of the lifting plate 36. The outer wall of one end of the worm 35 rotates through the outer wall of one end of the support plate 2 and is coaxially fixedly connected to a rotating wheel 39.

[0024] Further as Figure 3 and Figure 4 As shown, it is worth mentioning that the adjustment component 5 includes a round block 51, the bottom end of the round block 51 is fixedly connected to the top surface of the placement table 4, a rotating block 52 is rotatably embedded in the center of the top of the round block 51, and an L-shaped rod 53 is fixedly connected to the top of the rotating block 52. A plurality of threaded holes 54 distributed in a circle are provided on the outer surface of the rotating block 52, and a limiting screw 55 is threadedly inserted into the outer surface of the round block 51, and the limiting screw 55 is threadedly connected to one of the threaded holes 54.

[0025] Further as Figure 1 As shown, it is worth noting that universal wheels 7 are installed at the four corners of the bottom surface of the base 1, and a computer host 8 is placed on the top surface of the base 1.

[0026] Further as Figure 1 As shown, it is worth mentioning that a mouse pad 9 is fixedly connected to the outer wall of one side of the placement platform 4, and a probe hanging ear 10 is fixedly connected to the outer wall of one side of the placement platform 4.

[0027] Further as Figure 2 As shown, it is worth mentioning that the inner wall of the slide groove 32 is slidably connected to the outer wall of the slider 37. Through the cooperation of the slide groove 32 and the slider 37, the lifting plate 36 is more stable when moving inside the cavity 31. The top ends of the two support columns 38 slide through the top surface of the support plate 2 and are fixedly connected to the bottom surface of the placement table 4. The support columns 38 are driven to move by the lifting plate 36 to achieve adjustment of the height of the placement table 4.

[0028] Further as Figure 2 and Figure 4 As shown, it is worth mentioning that the width of the lifting plate 36 is the same as the width of the cavity 31, which maximizes the diameter of the support column 38 and provides a more stable support effect for the placement table 4. The outer wall of one side of the transverse section of the L-shaped rod 53 is rotatably connected to the display screen 6, and the distance between the display screen 6 and the operator is adjusted by controlling the rotation of the L-shaped rod 53.

[0029] In summary: when operating the ultrasonic bone densitometer, the staff first rotates the wheel 39 to drive the worm 35 according to the operator's height. Under the meshing action, the worm 35 drives the worm wheel 34 to rotate, thereby rotating the threaded rod 33. Through the cooperation of the slide groove 32 and the slider 37, and at the same time under the action of the thread, the lifting plate 36 moves upward on the threaded rod 33, thereby driving the support column 38 to move upward, so that the height of the placement table 4 increases, thereby making it easier for operators of different heights to operate the bone densitometer, effectively avoiding the problem that the height of the bone densitometer is difficult to match the height of the operator.

[0030] When the operator uses the display screen 6, he turns the limit screw 55. Under the action of the thread, one end of the limit screw 55 gradually moves away from the threaded hole 54. When one end of the limit screw 55 is completely separated from the threaded hole 54, the limit on the rotating block 52 is released. At this time, the L-shaped rod 53 is rotated to drive the display screen 6 to move, and the distance between the display screen 6 and the operator is adjusted. When the display screen 6 moves to a suitable distance, the limit screw 55 is rotated in the opposite direction to be inserted into one of the corresponding threaded holes 54, and the rotating block 52 is limited again. The operation is simple, and the problem of difficult adaptive adjustment of the distance between the operator and the computer display is effectively avoided.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
