Description
Technical field
The present invention relates to circadian rhythm disorder therapeutic instrument, particularly a kind of manufacture method of utilizing therapeutic instrument He this instrument of monochromatic light therapy circadian rhythm disorder.
Background technology
Recently a great discovery is arranged in field of biology, exactly in retina except rod cell that everybody was familiar with experience the cone cell of red, green, blue, also have a kind of photoreceptor cell to come judgement time, can adjust people's circadian rhythm (circadian rhythm) by their response by light.The main sensitive wave length of these found new photoreceptor cells is between 420-500nm, and this wave band that is to say that in the aeruginous spectral region these cells are very responsive to high colour temperature.At noon the time-division, the colour temperature of natural light will reach 6000-20000K, and time-division between the lights, colour temperature is reduced to about 2000K.The cyclically-varying of natural light colour temperature and people's circadian rhythm are synchronous.The evolution in millions of years of human process has formed circadian system, and it is coordinating the running of health each several part, makes it neat as one, with the biochemical function operation in an orderly manner on time of guaranteeing health.
But the circadian rhythm system that this natural light forms in human body in the industrial society of today, is changed regularly, and the mankind have been formed many adverse influences.In nowadays nearly all industry, round-the-clock running has become standard, people more are the irradiation that receives dull artificial light source daytimes, add the break tour at night and stride time zone flight travelling, these all affect the normal operation of the rhythm and pace of moving things system of human body, make it phase shift, even various biorhythies get muddled in the body.Regular circadian rhythm variation has brought huge physical and psychological pressure, is having a strong impact on people's health, activity in production, jeopardizes people's life sometimes or causes great accident.Therefore develop that a kind of effectively to regulate the circadian brand-new lighting source of human body very necessary, the circadian position phase that it can change the people both economical, easily reduces the resistance of position phase shift, works at night and strides time zone flight travelling thereby adapt to rapidly; Simultaneously, the best performance time that it can also adjustment movement person's competitiveness, adapt to the needs of match; Regulate patient's biorhythm, adapt to needs of medical treatment or the like.
Visible light therapy is meant the method for using the luminous ray treatment disease that can cause the retina light sensation with suitable intensity and time, and it can influence the time and the length of sleep, improves the emotion and the physiological situation of depressive illness.Up to the present, the used instrument of treatment has developed the three generations.The light source of first generation instrument is full gloss spectrum or the fluorescent lamp that produces cold white light, and about 2500lx illumination is provided; Second generation instrument is through improving, and has advantages such as miniaturization, portable, aesthetic in appearance, easy operating, and it has filtered out ultraviolet and blue light fully, and about 10000lx illumination can be provided.About 1 foot away from eyes of patient be of the fluorescent screen of this light source reaches work surface from top to bottom, and the light of a not too dazzling undertint is provided, and generally can both tolerate; The instrument of the third generation and dazzling rayed relatively, with outdoor morning of computer simulation spring and summer and dusk progressive dim light, the situation in the time can sleeping according to the patient after the dark adaptation provides the rayed of dim relatively dynamic change.Use strong illumination, energy antidepressant, correction is drowsiness, change is slept cycle and pattern.
During treatment, be divided into daystart, noon, treatment at night by the time for the treatment of.The time that daystart generally begins serial therapy can be arranged in clear-headedly carries out after 10 minutes morning, all should be in the Most patients treatment early than the recovery time on basis, the benefit of daystart treatment is to make the 24 hours period rhythm and pace of moving things in advance, and the change of this available mensuration melatonin at night secretion time confirms; The situation that the quality of antidepressant effect can shift to an earlier date according to the cycle and deciding, after waking up, custom carries out 10000lx, 30 minutes treatment, antidepressant effect and melatonin secretion and treatment time are remarkable negative correlation, in order to improve therapeutic effect as far as possible, the clinicist can measure the melatonin in patient's saliva or measure the method for hypothermia period and infer the excretory time of its melatonin.Noon treatment, effect be not as good as daystart and night, but can be used for the adjustment of the 24 hours period rhythm and pace of moving things.Night, treatment generally was arranged in 9:00～10:00 in evening, the precontract of promptly sleeping 2 hours.Treat used light source and be divided into high light, weak (secretly) light according to the size of illuminance.The high light treatment refers to illuminance 〉=2500lx; Weak (secretly) light treatment refers to illuminance≤500lx.In addition, the length according to treatment time is divided into long time and treatment in short-term.Long time refers to treatment time 〉=2 hour; Refer to treatment time≤1 hour in short-term, in general illuminance is big more, and used light application time is short more, and vice versa.
Long-time high-intensity white light will be brought nearly 42 kinds side effect, the most important thing is, nearest theoretical research shows, in traditional white light phototherapy, the existence of spectrum opposition effect (spectral opponency) make white light to circadian draw far below monochromatic light, and the circadian rhythm draw with blue light (420-500nm) is the strongest in the monochromatic light.It is calculated that, under the equal-wattage, the 2-5 that the draw of blue light is about reddish yellow light doubly, 185 times of white light.On the other hand, when 100 times of the light intensity decreasings of blue light, its traction effect to the rhythm and pace of moving things just reduces half, thus use at present monochromatic light particularly blue light to change the research of biorhythm a lot.
Usually adopt LED as blue light source.LED is that semiconductor electronic, hole-recombination are luminous, realizes that than being easier to monochromatic light light source, traditional light source obtain the monochromatic light light source and then must can cause higher optical energy loss but use electric filament lamp to add optical filter by professional equipments such as monochromators.Along with the development of GaN sill and device technology, the monochromatic light LED of the long-life blue light-green glow of high efficiency is very easy to obtain.
The someone has applied for the patent that some utilize led light source change human body circadian rhythm (or biological clock) at present.As the United States Patent (USP) (US 6350275) in June, 1998, its used light source is the blue green light LED of 420-575nm, and paster (SMD) LED is installed on the interior embodiment as it of spectacle frame.This patent has also been used the application-specific IC system that transfers bundle, regulates wavelength and regulate brightness, and LED drives by rechargeable battery.The difficult point of this patent is the design of integrated circuit, and weak point is, the one, because the luminescent spectrum width of LED is in 20nm in the market, if wavelength-tunable, then the number of devices of SMD LED will be very many, be unfavorable for the installation in mirror holder, and the 2nd, angular adjustment is in fact also quite difficult, need be installed in the LED of diverse location, different encapsulation angles in a large number, this will increase cost in light source and mirror holder design.Crucial a bit is, the method that this patent provides can't weaken the axial light intensity of led light source, and this may cause local damage to retina, causes very big risk thereby it is promoted the use of.
