Description

Technical Field

[0001] This utility model relates to the field of ultrasonic testing technology, specifically to a bone density ultrasonic testing device. Background Technology

[0002] Ultrasonic bone densitometers are used to diagnose osteoporosis, a condition characterized by low bone density. Ultrasound waves travel through the body at a speed corresponding to the bone mineral content. Therefore, by measuring the speed of ultrasound propagation within the body, the amount of bone mineral in the sample can be determined. Ultrasonic bone densitometers utilize this principle, measuring the speed of ultrasound propagation within the bone to quantitatively determine bone density. Currently, to improve the accuracy of ultrasound propagation speed measurements, the calcaneus, a bone rich in cancellous bone, is often used for ultrasound bone density testing.

[0003] When using a dual-energy X-ray calcaneal bone densitometer for examination, after evenly applying an appropriate amount of coupling agent to the foot examination area, the examinee needs to place their lower leg against the leg support plate and keep their foot firmly against the plate. However, due to differences in leg length and leg extension angle among examinees, the examinee can only exert force to keep their foot firmly against the support plate, making it difficult to securely fix the leg on the leg support plate. This causes the calcaneal examination position to easily shift, affecting the examination results.

[0004] Therefore, it is necessary to propose a bone density ultrasound testing device that is easy to use, provides stable foot placement, and delivers accurate results. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a bone density ultrasound detection device that is easy to use, provides stable foot placement, and provides accurate detection results.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0007] A bone density ultrasound testing device includes an adjustment seat fixed to a base plate and a calcaneal bone densitometer that can slide left and right on the base plate. The adjustment seat is provided with a seat, which can be adjusted along the tilt direction of the leg placement plate in the calcaneal bone densitometer. The front end of the seat extends towards the calcaneal bone densitometer with a support plate, and the support plate is parallel and aligned with the leg placement plate.

[0008] In one embodiment of this utility model, the bottom of the seat surface is provided with multiple chair legs at the same angle as the support plate, and the adjustment seat is provided with multiple guide holes corresponding to the chair legs at the same angle as the support plate, and an electric screw is provided at the bottom of the guide hole.

[0009] In one embodiment of this utility model, a T-shaped guide block is provided at the bottom of the calcaneal bone densitometer along the left-right direction, and a guide groove corresponding to the guide block is provided on the upper surface of the base plate along the left-right direction.

[0010] In one embodiment of this utility model, an installation groove is provided on the upper surface of the base plate along the left and right direction, and a transverse movement mechanism is provided in the installation groove. The transverse movement mechanism is connected to the bottom of the calcaneal bone densitometer.

[0011] In one embodiment of this utility model, the transverse movement mechanism is a reciprocating screw, and the moving block of the reciprocating screw is connected to the bottom of the calcaneal bone densitometer.

[0012] In one embodiment of this utility model, a backrest is provided at the rear of the seat surface, and mounting plates are fixed on the left and right sides of the seat surface. Multiple rollers are evenly arranged between the two mounting plates along the front-back direction of the seat surface. A seat plate is provided above the rollers, and both ends of the seat plate are connected to both ends of the same protective cover. The protective cover passes around the bottom of the two outermost rollers.

[0013] As one embodiment of this utility model, an inverted U-shaped limiting plate is fixedly provided on the inner side of the mounting plate to limit the seat plate and prevent the seat plate from detaching from the seat surface.

[0014] In one embodiment of this utility model, a handrail is provided on the top of the mounting plate.

[0015] In one embodiment of this utility model, a transmission box is provided on the outer side of one of the mounting plates. The rotating shaft of the roller passes through the mounting plate and is fixedly connected to a sprocket located in the transmission box. Multiple sprockets in the transmission box are connected together by a chain, and one of the sprockets is connected to a servo motor located on the side wall of the transmission box.

[0016] The beneficial effects of adopting the above technical solution are as follows:

[0017] The bone density ultrasound testing device provided by this utility model is easy to use. After the examinee sits on the seat, by adjusting the examinee's fore-and-aft position on the seat, the knees are positioned at the front of the seat, and the lower legs naturally rest against the support plate. Since the support plate is aligned with the leg placement plate on the calcaneal bone densitometer, adjusting the seat height allows the examinee's feet to rest firmly on the foot placement plate, thus ensuring a stable foot placement and avoiding inaccurate test results due to improper force exertion or incorrect foot placement. The roller and seat plate, combined with armrests, facilitate the examinee's adjustment of the fore-and-aft position on the seat. By incorporating guide grooves and guide blocks between the base plate and the calcaneal bone densitometer, the lateral position of the calcaneal bone densitometer is easily adjusted when testing the examinee's left and right feet.

[0028] like Figure 1 The illustrated bone mineral density ultrasound testing device includes an adjustment seat 21 fixed on a base plate 1 and a calcaneal bone densitometer 13 slidably mounted on the base plate 1. The calcaneal bone densitometer 13 is equipped with a leg placement plate 14 and a foot placement plate 15. A seat is mounted on the adjustment seat 21, and the seat's height is adjustable along the tilt direction of the leg placement plate 14 within the calcaneal bone densitometer 13. A support plate 4 extends from the front end of the seat surface 2 towards the calcaneal bone densitometer 13, and the support plate 4 is parallel and aligned with the leg placement plate 14. The front plane of the support plate 4 is on the same plane as the placement plane of the leg placement plate 14.

[0029] The bone density ultrasound testing device is easy to use. After the examinee sits on the seat 2 of the chair, by adjusting the examinee's position on the seat 2, the knee is positioned at the front of the seat 2. At this time, the lower leg is naturally pressed against the support plate 4. Since the support plate 4 is aligned with the leg placement plate 14 on the calcaneal bone densitometer 13, by adjusting the height of the chair, the examinee's foot can be pressed against the foot placement plate 14, thereby achieving a stable placement of the examinee's foot and avoiding inaccurate test results due to improper force exertion or incorrect foot placement by the examinee.

[0030] As shown in the figure Figure 4 and Figure 5 As shown, the bottom of the seat 2 is provided with multiple chair legs 20 at the same angle as the support plate 4. The adjusting seat 21 is provided with multiple guide holes 22 corresponding to the chair legs 20 at the same angle as the support plate 4. An electric screw 23 is provided at the bottom of the guide hole 22. The electric screw 23 is connected to the lower end of the chair leg 20 and is used to adjust the height of the seat.

[0031] like Figure 3 As shown, a T-shaped guide block 17 is provided at the bottom of the calcaneal bone densitometer 13 along the left-right direction. A guide groove 16 corresponding to the guide block 17 is formed on the upper surface of the base plate 1 along the left-right direction, and the guide block 17 is engaged inside the guide groove 16. By providing the guide groove 16 and the guide block 17 between the base plate 1 and the calcaneal bone densitometer 13, it is convenient to adjust the left-right position of the calcaneal bone densitometer 13 when testing the left and right feet of the test subject.

[0032] As a further optimization, such as Figure 8 As shown, a mounting groove 18 is formed on the upper surface of the base plate 1 along the left-right direction.

The protective cover 9 passes around the bottom of the two outermost rollers 7. When the protective cover 9 passes around the bottom of the rollers 7, it is located between the rollers 7 and the seat surface 2. The protective cover 8 is made of soft and wear-resistant materials such as cloth and rubber. By setting up the rollers 7 and the seat plate 8, combined with the armrests 10, it is convenient for the tester to adjust the front-back position on the seat surface 2.

[0034] like Figure 2 As shown, an inverted U-shaped limiting plate 6 is fixedly provided on the inner side of the mounting plate 5 to limit the seat plate 8 and prevent the seat plate 8 from detaching from the seat surface 2. The two vertical parts of the limiting plate 6 are located at both ends of the mounting plate 5 and are used to limit the seat plate 8 when it moves back and forth; the horizontal part of the limiting plate 6 is flush with the top of the mounting plate 5 and restricts the seat plate 8 below the horizontal part.

[0035] The mounting plate 5 is provided with an armrest 10 on its top. When the tester adjusts the fore-and-aft position on the seat, holding the armrest 10 makes it easier to exert force.

[0036] like Figure 8 As shown, as a further optimization, a transmission box 11 is provided on the outer side of one of the mounting plates 5. The rotating shaft of the roller 7 passes through the mounting plate 5 and is fixedly connected to a sprocket located in the transmission box 11. Multiple sprockets in the transmission box 11 are connected together by a chain, and one of the sprockets is connected to a servo motor 12 located on the side wall of the transmission box 11. An automatic adjustment button marked with forward and backward arrows is provided on the seat.
