Embodiment Construction

[0049] The present invention will be further described through specific embodiments below in conjunction with the accompanying drawings.

[0050] The hydraulically driven bone density increaser has a length, width, and height of 40 cm, 30 cm, and 30 cm, respectively. Base plate 5 is a steel plate with a thickness of 4 millimeters, and base plate 5 is placed on the top of the lower rubber damping pad 6, which is a rubber plate with a thickness of 2 mm. Column 3. The vibrating plate 2 is a steel plate with a thickness of 2 millimeters, and the column 3 is provided with linear bearings up and down, and a hydraulic oil pump 9, a hydraulic oil cylinder 4 and a controller 7 are arranged on the base plate 5. The hydraulic cylinder 4 is connected to the vibrating plate 2, and the vibrating plate 2 is connected to the upper rubber damping pad 1. Upper rubber damping pad 1 is a 2 mm thick rubber plate. A controller 7 is arranged in the bone density increaser, and a 2D electro-hydraul...

Abstract

The invention belongs to equipment for increasing human bone density, and is a hydraulically driven bone density increaser. The disadvantages of the prior art are that the drug treatment for improving bone density is expensive, has side effects, and has no obvious effect. The bottom plate (5) of the present invention is placed on the upper part of the lower rubber shock absorber (6), and columns (3) are respectively connected on both sides between the vibration plate (2) and the bottom plate (5); An oil pump (9), a hydraulic oil cylinder (4) and a controller (7); the controller (7) is provided with a 2D electro-hydraulic control valve (8). The advantages of the present invention are: small size, light weight; stable and automatic frequency adjustment; easy direction change, which can conveniently realize the conversion of linear reciprocating motion; oil is used as the working medium, and the relative moving surfaces of the components can be self-lubricated and wear-resistant. Small size, long service life; easy operation and control, high degree of automation; no drugs, no side effects.

Description

technical field [0001] The invention belongs to equipment for increasing human bone density, in particular to a hydraulically driven bone density increaser. Background technique [0002] Bone density, short for "bone mineral density", is a major indicator of bone strength. Osteoporosis is caused by the reduction of bone density and the thinning and brittle bone structure, which makes people unable to bear the weight of the body and the impact of external force, resulting in pain and fractures. Osteoporosis is a common chronic disease in the world, especially in the elderly, and the occurrence time may be as long as several decades. For example, women lose 1-2% of bone mass every year. Because bone loss occurs unconsciously, it is not easy to detect, and it is only discovered when a fall, fracture or pain occurs. Fractures caused by osteoporosis in the elderly lead to long-term bed rest, disability, and other serious complications, such as pulmonary embolism, decubitus ulce...
