Embodiment 1
[0040] The specific process of this embodiment is as follows:
[0041] A total of 48 female postmenopausal osteoporosis patients, aged 52-64 years old, were measured with a dual-energy X-ray bone densitometer (purchased from Lunar, USA) 2-4 Bone density and bone density are lower than the peak bone density of the corresponding age. The heart, liver, kidney and other endocrine and metabolic status of all patients were normal, and no one took hormone drugs within 3 months.
[0042] Before treatment, all subjects had venous blood drawn on an empty stomach at 9 am, and the serum was collected after centrifugation and stored at -20°C for later use. The enzyme-linked immunoassay measurement kit was used to measure the serum anti-tartrate phosphatase 5b content in the patient's blood. According to age, bone density and serum osteocalcin level, 48 patients were equally divided into vibration treatment group and estrogen treatment group, with 24 patients in each group. Vibration group lin...
Embodiment 2
[0050] The specific process of this embodiment is as follows:
[0051] There are 18 clinical patients with lower limb fractures, 10 males and 8 females, the youngest is 26 years old, and the oldest is 53 years old. They used axial vibration wave stimulation with intensity of 8mN and frequency of 20Hz (waveforms like image 3 Shown), once a day for 1 hour each time for 45 days.
[0052] The evaluation criteria for curative effect are: (1) Significantly effective: joints move freely, functional activities return to normal, local swelling subsides, no tenderness and discomfort. (2) Improvement: The stiffness of the joints has been improved, the range of motion of the joints has increased compared with before treatment, the swelling has subsided, and there is slight discomfort. (3) Ineffective: Vibration therapy for 45 days did not significantly improve the symptoms and signs of fractures.
[0053] The results of the study 45 days later showed that after the vibration treatment, there ...

Abstract
The invention discloses a bone injury/osteoporosis treatment bed based on high-frequency low-intensity vibration. The treatment bed includes a bed body which is provided with a head rest and a pedal at the two ends respectively. The bottom part of the bed body is provided with an angle adjuster. The angle adjuster adjusts the bed body at the side of the head rest to rise for 0-10 degrees. The pedal is subjected to a preloading force applied by the gravity. The pedal contacts a motor. Vibration stimulation is generated through driving of the motor. A control platform controls the linear motor through a feedback control module. The bone injury/osteoporosis treatment bed based on the high-frequency low-intensity vibration adopts vibration-wave stimulation in a horizontal direction and the bed head is adjustable with a raised oblique range of 0-10 degrees. On the one hand, better force bearing of a patient is facilitated and the distance of the head part and the foot part is adjustable according to the height of the patient and on the other hand, the preloading stress of the gravity of the patient body can be borne so that bone absorption rate of the patient of osteoporosis induced by lack of female hormone can be restrained significantly and thus bone loss is restrained.
Description
Technical field [0001] The invention belongs to the technical field of bone injury and osteoporosis treatment, and relates to a bone injury / osteoporosis treatment bed based on high frequency and low intensity vibration. Background technique [0002] Bone injury and osteoporosis are the most common clinical diseases, and their clinical incidence is high, causing a great burden on the patient's body and psychology. The clinical manifestations of osteoporosis are bone loss, increase in bone fragility, and damage to the fine structure of bone tissue, often causing fractures and permanent loss of limb function. According to statistics, there are more than 200 million patients with osteoporosis in the world, and the number of patients in my country is as high as 90 million. my country’s annual medical and economic expenditure for osteoporosis is as high as 108 billion yuan. Osteoporotic fractures The high disability rate and fatality rate is also one of the major clinical problems. As...
