Description
Technical field
The present invention relates to medical instruments field, in particular, relate to a kind of weightlessness of space spacefarer skeletal muscle function maintenance instrument.
Background technology
The bone loss that weightlessness causes and amyotrophy are the important restriction factors of implementing long-term space flight task.Therefore, for medium-term and long-term space flight, attach most importance to skeleton and musculature, development of new be to solve spacefarer's skeleton that long-term space flight causes and the key of muscle degeneration or the medical problems such as ground crowd's skeleton and musculature disease in rail skeleton and muscle integrated protection counterdevice.
Research in recent years finds that Mechanical vibration stimulation as a kind of Noninvasive physical factor, all proves the formation that can promote to a certain extent newborn skeleton in the zoopery of having carried out and human experimentation, prevents useless generation with the property bone loss.
The state Rubin of university in USA New York and partner thereof find the mechanical vibration of certain frequency, short arc can promoting bone growing speed, increase the bone amount, effectively prevent bone loss.Tail-suspension simulated weightlessness rat is accepted the mechanical vibration (90Hz of low amplitude every day, 0.25g) 10 minutes, after 28 days, the bone formation speed of simulated weightlessness rat distal tibia is compared matched group and zero difference, and simulated weightlessness makes bone formation speed reduce 92%, illustrates that mechanical vibration can effectively suppress the bone loss that weightlessness causes.Rubin etc. apply 30Hz to the sheep hind leg, 0.3g Mechanical vibration stimulation, 20min/d, 5d/week, found afterwards that mechanical stimulus made the bone density of distal femoral spongy bone increase by 34.2% in 1 year, bone formation speed and mineralizing surface integration have not increased by 2.1 times and 2.4 times.The complex vibration that the mice ulna is applied sinusoidal wave and random vibration signal that studies show that of Alesha BC etc. can obviously improve bone formation speed.Jeremy ML etc. studies have shown that the certain sky of insertion in the vibration processes have a rest the time (intermittently carrying out again the vibration of next circulation after the sustained vibration of 1s behind the 10s) compare the average bone formation speed that sustained vibration more can promote skeleton periosteum surface.
For the amyotrophy in the space travel, it has been observed that the physical exercise mode may have certain effect.On the international space station, the device that much muscle is performed physical exercise is arranged, these devices comprise: treadmill (maintaining the physiological function of oxygen metabolism), bicycle ergometer (maintenance aerobic capacity), resistant exercise device (keeping muscle strength and bone mineral content), and pinch meter (the hand strength when keeping extravehicular activity).Practice shows that carrying out a large amount of for a long time exercises can resist the minimizing of muscle aspect weight and muscular strength, but can not play completely protective effect.The at present Chinese scholars impact of electricity irritation on muscle that begun one's study, research is found, the skin mechanoceptor is carried out the massage of electricity irritation and muscle all can reduce hind leg go the to load amyotrophy of rat, but the compound mode of the frequency of electricity irritation, voltage, electric current is also indefinite, and not yet development is fit to the muscle massage machine that use in the space.
