Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to a bone density detection auxiliary device. Background Art

[0002] Bone density measurement is a method of indirectly reflecting bone density by calculating the value through the amount of X-ray absorption by bone. Dual-energy X-ray bone density measurement is commonly used in clinical practice. Bone density measurement can be divided into three categories: qualitative, semi-quantitative and quantitative. Among them, qualitative and semi-quantitative cannot be used as sensitive indicators for observing early changes in bone density, so quantitative bone density examination is still an important means today. Bone density measurement is of great significance in medicine, and is of great significance for the occurrence, diagnosis, treatment, prognosis and follow-up observation of osteoporosis, osteomalacia, osteitis fibrosa and other diseases that affect calcium and phosphorus metabolism.

[0003] Announcement No. CN203898354U discloses a bone density detection device. The detection slot can detect hands and feet. When detecting feet, the baffle is against the soles of the tester's feet, and the support plate supports the tester's calves. When detecting hands, it is only necessary to put the hands on the support plate. At the same time, in order to ensure the hygiene of the instrument, disinfection pads are provided on the support plate and the baffle. In addition, for reliable limiting, finger grooves can be provided on the disinfection pad of the support plate, and sole grooves can be provided on the disinfection pad of the baffle. In order to further enrich the functions of this device, we have also integrated a touch control screen and a printer, which can directly realize the printing of the test results on the device without connecting to the outside world. However, the patent still has the following problems in actual use:

[0004] Although the bone density detection device can detect the patient's legs and arms, it cannot fix the legs and arms during the detection, resulting in the detection instrument shaking due to the patient's movement during the detection, thereby affecting the accuracy of the detection result. At the same time, the detection device cannot be adjusted accordingly and cannot adapt to patients of different body shapes.

[0005] Therefore, a bone density detection auxiliary device is proposed to solve the above-mentioned problems. Summary of the invention

During the test, the patient's body can be supported by the positioning support bracket 110 to improve the comfort of the patient's test, thereby reducing the probability of the patient moving around during the test and improving the accuracy of the patient's bone density test. By rotating the adjustment knob 117, the adjusting bidirectional threaded rod 118 is driven to rotate, so that the two adjusting threaded sleeves 119 move relative to each other and the adjusting rotating rod 120 is driven to rotate, so as to adjust the height of the adjusting support plate 121.

At the same time, the sliding connection between the positioning sliding rod 104 and the positioning sliding sleeve 105 inside the positioning bracket 103 is used. When the patient's body is pressed on the positioning support bracket 110, the positioning support bracket 110 drives the positioning lifting plate 108 to descend. Under the action of the positioning rotating rod 107, the positioning sliding sleeve 105 drives the clamping bracket 111 to move relatively, and the patient's body is fixed by the variable clamping arm 114 at the end of the clamping threaded rod 112.
