Embodiment 1

[0023] Embodiment 1. Device for preventing and treating spatial bone loss

[0024]Referring to Fig. 1, the device of the present invention includes a limit block 1, a guide rail 2, a fastening knob 3, a sliding plate 4, a shoulder fixator 5, a waist fixer 6, a knee joint fixator 7, an elastic drawstring 8, a vibrating table 9. Pull cord 10, pulley 11, torque motor 12, bracket 13 and drawstring fixing frame 14, guide rail 2, fastening knob 3, sliding plate 4, vibrating table 9, pulley 11, torque motor 12, support 13 and drawstring The fixed frame 14 is all made of aluminum-magnesium alloy, and the limit block 1, the shoulder fixator 5, the waist fixer 6, and the knee joint fixer 7 are made of carbon / carbon composite material. Limiting baffles 1 are fixed at both ends of the guide rail 2, and a fastening knob 3 for braking or fixing the sliding plate is arranged at the front end of the sliding plate 4. The shoulder fixer 5 is inserted into the fixing groove of the sliding plate...

Embodiment 2

[0027] Embodiment 2. A device for preventing and treating bone loss caused by weightlessness in ground-based simulated space

[0028] Referring to Fig. 2, the core components of the device of the present invention are the same as the device for preventing and treating bone loss due to space gravity, except that the device for foundation simulation includes a support platform 15, and the sliding plate 4 can move along the support platform 15 within the range allowed by the guide rail. Sliding freely on the length direction of the support table 15 and the slide plate 4 through the guide rail 2 combination. The torque motor 12 is positioned at the rear of the slide plate 4, and is fixed on the support table 15 by a bracket 13, so that the direction of vibration of the table top 16 is horizontal, that is, consistent with the sliding direction of the slide plate. When the human body receives the vibration stimulation, it lies flat on the sliding plate 4, and the specific connection...

Abstract

The invention relates to a device for preventing and treating space weight loss bone loss, wherein two ends of track are fixed with limit blocks; the sliding plate is mounted on track, whose front has fixing button; the sliding plate is mounted with should fixer, waist fixer, and knee fixer; the vibrator is along the extending line of track, to connect fixing surface via support; one end of drawing line is fixed on sliding plate, bypassing the block of fixing face, while another end is connected to the rotation wheel of torque motor; the torque motor via drawing line draws sliding plate to pressurize the vibrator, to function the vibration on the human body. The invention can reduce side effect with high safety.

Description

technical field [0001] The present invention relates to a medical mechanical device, in particular to a device for stimulating the skeletal system by mechanical stress. Background technique [0002] One of the most important factors affecting the health of astronauts in space flight is weightlessness. In a weightless environment, the load on bones and muscles decreases, leading to bone loss and muscle atrophy in astronauts. Spaceflight, even a short-term flight, can cause bone loss, and the resulting decline in bone density recovers very slowly after returning to Earth, which in turn causes osteoporosis and fractures and other motor system injuries. In addition, bone loss increases the risk of cardiovascular or soft tissue calcification and urinary calculi. Bone loss in a weightless environment is mainly due to the disappearance of the load on the bones when they are on the ground, and the bones cannot feel the impact of loads generated by movement on the ground, resulting ...
