Technical Field

[0001] The present application relates to the technical field of bone densitometers, and in particular to a sliding support structure of a dual-energy X-ray bone densitometer. Background Art

[0002] A bone densitometer is a medical testing instrument that measures human bone minerals and obtains various related data. The test results of a bone densitometer are mainly T-values, but also include Z-values, bone density, bone mass and other data. The results of a bone densitometer using dual-energy X-rays are more accurate and are the gold standard for bone density adopted by the World Health Organization. In the early 21st century, the mainstream bone densitometers on the market were divided into two categories: dual-energy X-ray bone densitometers and ultrasonic bone densitometers. In addition, there are X-ray bone densitometers, but they are not dual-energy technology, and there are single-photon bone densitometers. This article mainly introduces the two mainstream bone densitometers on the market.

[0003] X-ray bone densitometer is a medical device, mainly composed of a bone density scanner host, application software and accessories. Most of the existing dual-energy X-ray bone densitometers detect specific positions of the ulna and radius of the forearm. Bone density, the full name of which is bone mineral density, is an important indicator of bone quality, reflecting the degree of osteoporosis and an important basis for predicting the risk of fractures.

[0004] However, existing bone densitometers are often equipped with a support platform of a fixed size, so that the patient lies directly on the platform, which is not convenient for adjustment according to the patient's body shape, and there is room for improvement. Summary of the invention

[0005] In order to facilitate adjustment of the length of the support platform according to the patient's body shape, the present application provides a sliding support structure of a dual-energy X-ray bone densitometer.

[0014] By adopting the above technical solution, with the help of the mutual cooperation between the blocking rod and the socket, the support plate can be fully fixed after the angle is adjusted, which helps to reduce the occurrence of the support plate detaching.

[0015] Optionally, a fixing rod for auxiliary fixation is threadedly penetrated through the other end of the outer surface of the guide plate, a fixing hole adapted to the fixing rod is opened on the inner wall of the guide groove, and one end of the fixing rod passes through the guide plate and is plugged into the inner wall of the fixing hole.

[0017] By adopting the above technical solution, a hydraulic rod is used to push the pallet, thereby improving the convenience of moving the pallet.

[0018] Optionally, the support seat, the support plate and the top of the pad are fixedly connected with Velcro hook surfaces for sticking and fixing below the protective pad, and the bottom of the protective pad is fixedly connected with Velcro fur surfaces that match the Velcro hook surfaces.

[0019] By adopting the above technical solution, the Velcro hook surface and the Velcro fleece surface are detachably fixedly connected, so the protective pad can be easily replaced and fixed.

[0020] Optionally, a positioning groove is provided on the top of the pad, a motor for driving is fixedly mounted on the inner bottom wall of the positioning groove, an output end of the motor is connected to a cam via a key, and an outer surface of the cam is pressed against the bottom of the headrest.

[0021] By adopting the above technical solution, the contact surface of the cam with the head support can be changed by rotating the output end of the motor and driving the cam to move, thereby changing the supporting angle of the head support.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1.

[0024] 2. Through the coordinated setting of the pad and the head support, different degrees of adjustment can be made according to the angle required by the patient's head, so that the head support can stably support the patient's head, thereby improving the practicality of the device;

[0025] 3. Through the setting of the protective pad, it can be directly laid on the top of the support seat, the support plate and the pad, thereby avoiding direct contact between the device and the patient. The detachable design of the protective pad allows the protective pad to be directly removed after use, which is more convenient for the staff to replace it, and it is easy to clean and also allows the device to be recycled for multiple times.

[0033] The present application embodiment discloses a sliding support structure of a dual-energy X-ray bone densitometer, referring to Figure 1 , including a support base 1, and four support legs 2 are arranged at the bottom of the support base 1. The four support legs 2 are fixedly installed at the four corners of the bottom of the support base 1, and are in contact with the ground at the bottom of the support base 1, so as to support the support base 1. The bottom of the support base 1 is fixedly connected with an anti-skid pad, which is arranged between the support legs 2 and the ground, and increases the friction between the support legs 2 and the ground, thereby ensuring the stability of the support base 1 during work, thereby improving the overall support stability of the device, and ensuring the stability of the device even when subjected to a certain thrust.

[0034] Guide grooves 3 for assisting sliding are provided on both sides of the outer surface of the support seat 1, and guide plates 4 for support are inserted into the inner walls of the guide grooves 3. The two guide grooves 3 are connected to the guide plates 4, and the ends of the guide plates 4 are connected to the ends of the support plates 7 through the rotating shafts, so that the guide plates 4 slide in the guide grooves 3, pushing the support plates 7 to slide in the direction of the guide grooves 3, and the support plates 7 rotate around the guide plates 4 with the help of the rotating shaft, so that the angle of the support plates 7 can be adjusted.

[0035] Slide blocks 5 are fixedly connected to the top and bottom of the guide plate 4, and slide grooves 6 are opened on the inner top wall and inner bottom wall of the guide groove 3.

[0037] In order to facilitate the position adjustment of the support plate 7 during operation, two mounting grooves 12 are provided at the end of the support seat 1, and hydraulic rods 13 are fixedly installed on the inner walls of the two mounting grooves 12. The ends of the two hydraulic rods 13 overlap with the ends of the support plate 7, and when the hydraulic rods 13 extend outward, the support plate 7 can be slid outward for adjustment, providing power for the sliding of the support plate 7, and the support plate 7 can be retracted in time when it is pushed, so as to avoid the hydraulic rods 13 from contaminating the patient's clothing.

[0038] The adjusted guide plate 4 and guide groove 3 are fixed with the help of fixing rods 10 and fixing holes 11 to ensure the stability of the support plate 7. After the fixing rods 10 and fixing holes 11 are disassembled, the support plate 7 can be pushed outward with the help of hydraulic rods 13, which makes it more convenient to adjust the device according to the needs of users.

[0039] In order to improve the convenience of adjusting the support angle during the operation of the pad 17, a positioning groove 18 is provided on the top of the pad 17, and the inner wall of the positioning groove 18 is connected to the head support 21 through a rotating shaft. A motor 19 is fixedly installed on the inner bottom wall of the positioning groove 18, and the output end of the motor 19 is connected to a cam 20 through a key, so that the motor 19 can drive the cam 20 to rotate, so that the outer surface of the cam 20 contacts the bottom of the head support 21, and then the rotation of the cam 20 changes the support angle of the head support 21, driving the head support 21 to rotate. With the setting of the positioning groove 18, the motor 19, the cam 20 and the head support 21 can be installed and fixed, and then the contact surface of the cam 20 with the head support 21 can be changed by driving the cam 20 by the motor 19, so as to change the support angle of the head support 21, thereby improving the practicality of the device.
