Description

Technical Field

[0001] The present application relates to the technical field of bone density detection, and in particular to a belt transmission structure of an axial bone dual-energy X-ray 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] Dual-energy X-ray bone densitometer obtains two kinds of energy, namely low-energy and high-energy photon peaks, through the X-ray tube ball passing through a certain device. After this photon peak penetrates the body, the scanning system sends the received signal to the computer for data processing to obtain the bone mineral content. The instrument can measure the bone mass in any part of the body with high accuracy and little harm to the human body. The radiation dose of detecting one part is equivalent to 1 / 30 of a chest X-ray and 1% of QCT. There is no problem of radiation source decay. It has been gradually carried out in major cities in my country and has a promising future.

[0004] However, the detection mechanism of existing bone densitometers is often in a fixed position. When patients need to lie on the instrument, they often need to lower their heads and bend over to prevent bumps. In addition, during the detection process, the position of the detection mechanism also needs to be frequently adjusted, so the overall practicality is not high. Summary of the invention

[0013] Optionally, one side of the top of the support plate is rotatably connected to a drive shaft, and one end of the drive shaft that penetrates into the support plate is connected to a drive gear via a key.

[0014] By adopting the above technical solution, the stability of the connection between the drive shaft and the drive gear is improved.

[0015] Optionally, a slot matching the driving gear is formed on the outer surface of the driving rod, and an inner wall of the slot is meshed with the outer surface of the driving gear.

[0036] The end of the support plate 8 is fixedly mounted with a bracket 14, which slides on the guide rod 6 and the driving rod 7 and drives the bracket 14 to slide inside the support seat 1 in a direction parallel to the guide rod 6. The inner wall of the bracket 14 is fixedly connected with a support plate 15, and two motors 16 are provided inside the bracket 14 to provide power for the rotation of the driving gear 10.
