Description
Technical field
This utility model relates to medical apparatus and instruments, particularly relates to wound therapeutic apparatus.Suitable in paralytic, the skin ulcer of diabetes patient and various common burn, scald, wound, wound clinical rehabilitation treatment.
Background technology
Biological wound-surface ulcer healing is an extremely complex process, including inflammatory phase, proliferative phase and 3 stages of reparation phase, each stage overlaps each other, interacts, and the cell related to includes platelet, inflammatory cell, vascular endothelial cell, fibroblast, epithelial cell etc..Often due to treatment and nursing is improper during healing, wound strength reduces, angiogenesis reduces, poor wound healing, aphtha causes that the thing of deeper ulcer happens occasionally, and even also can cause complication further, so, not only result in the course of disease to extend, expend huge, also can face amputation to cut off the danger of fundamental tissue and the bone infected.The wound being difficult to heal has a strong impact on the quality of life of individual, it is also possible to cause EI.Skin wound is relatively common in adult.The incidence rate of wound seems the growth along with population life expectancy and increases.This kind of sufferer is in rising trend in mid-aged population in recent years.How to promote wound surface quickly-healing, reduce its disability rate and medical expense, be one of the problem of medical domain research.
Managing important aid as wound, the naturopathy such as ultrasonic therapy and electrotherapy is cited equally in clinic.These therapies seem to be advantageous for, but they have limitation, can not always achieve satisfactory results.Phototherapy at the method Medium and low intensity treating these pathological changes is a significant therapy approach.
This therapy mainly have employed low-energy laser (LASER) or light emitting diode (LED) as light device, selects suitable wavelength, the light of suitable dosage irradiates biological tissue, upon laser irradiation, can make Ca in cell2+Concentration increases, and then the synthesis of active cell internal protein.Different cells (leukocyte, fibroblast, keratinocyte etc.) can produce different physiological effect (bactericidal activity, synthetic protein and cytokine, hyperplasia) after being activated, reaches the clinical therapeutic efficacy of different aspect.Simultaneously laser irradiates nitrosyl radical haemoglobin complexes (NO-hemoglobin and cytochrome C-NO) and it can be made to discharge free NO, NO can distend the blood vessels, increase blood flow, improve blood circulation, and this is also beneficial to the healing of wound.
At present, dispute is there is also about low-intensity laser irradiation application in wound healing etc., on the one hand because of its action effect unstability, strong depend-ence optical parametric is relevant with itself for this, including different wavelength, power density, energy density, irradiation frequency (continuous wave or impulse wave), exposure time and treatment number of times clinically, treatment interval etc., it is likely to and the optical property of living organism self, Functional Characteristics etc. are relevant, or there is relation with these two aspects, and it is directed to the different conditions of different living organism or body, how different symptoms selects suitable radiation parameters, then need to study the biological agent mechanism of LOIHT and rule further.On the other hand also because present laser remains high, impact is universal.
Utility model content
In general, the more long penetration capacity of optical wavelength is more strong, and different wavelength can penetrate skin histology and arrive different positions, is absorbed by color bases different in tissue simultaneously.
Research shows, 150nm～380nm (ultraviolet) penetration range is less than 0.1mm, 390～470nm (bluish violet to navy blue) penetration range is about 0.3mm, 475～545nm (blue to green) penetration range is about 0.3mm～0.5mm, 545～600nm (yellow is to orange) penetration range is about 0.5mm～1mm, 600～650nm (redness) penetration range is about 1mm～2mm, 650～950nm (dark red-near infrared ray) penetration range is about 2mm～3mm, and 950～1200nm (near infrared ray) penetration range is about 1mm.
The absorption of light depends primarily on the chromophore (hemoglobin and melanin) of wavelength and Main Tissues.Red light is absorbed by line grain cylinder cell pigment C oxidase, and infrared wavelength is the cell membrane by specific protein directly absorbs, and two kinds of approach cause identical optical-biological reaction.Absorbing wavelength is less than 600nm.Because the spectrum of these reasons, HONGGUANG and near infrared light has a treatment window.When 580～860nm spectrum is analyzed, it was found that four active SPECTRAL REGION, 2 redness (613.5～623.5nm, 667.5～683.7nm) and 2 near-infrareds (peak from 750.7～772.3nm, 812.5～846nm).It is that infrared ray is minimum that light near these wave bands is absorbed by the hemoglobin of tissue, and the penetration into tissue of light is strong.The organization internal that gos deep into of these light maximizings plays therapeutical effect, and accelerating wound healing has positive effect, and wavelength 730 and 980nm then affect less, and different wavelengths of light can be had different absorption characteristics with chromophore and explain by this.They are commonly used for the skin texture for the treatment of deep layer clinically, for instance sebaceous gland.
Experimentation shows, removes wound secretion, normal saline cleaning wound surface, then adjusts optical parametric and selects the hot spot of diameter 4cm to irradiate wound surface in continuous wave mode to carry out low light level treatment.Irradiating according to wound surface size subregion, each hot spot irradiates 5 minutes, irradiates complete with aseptic dressing wrapping wound surface.Treat every day 1 time, within 10th, be a course for the treatment of, 5 days, interval between the course for the treatment of.Result of study confirms, power density ranges for 3.5mW/cm2～(5mW/cm2～12.38mW/cm2～) 20mW/cm2, energy density ranges for 2.1J/cm2～(3J/cm2～7.43J/cm2～) 12J/cm2Wavelength selects 633nm/635nm/688nm/810nm/833nm to irradiate wound respectively can improve the microcirculation of wound granulation tissue, granulation tissue blood flow and blood capillary length and area density is made to increase, these all make angiogenesis factor secretory volume increase, thus promoting the growth of wound surface new vessels and the healing of wound.And with 10mW/cm2, 2.1～2.4J/cm2Effect is best.Additionally experiments show that, irradiate number of times and present parabola effect with therapeutic effect, namely after irradiation number of times reaches maximum, being further continued for increasing number of times, stimulation weakens on the contrary, even becomes inhibitory action.
Diabetic wounds is because blood flow declines, and wound infection is a subject matter.Studying discovery recently, blue light irradiates can also interfere significantly on biosystem, and blue light is used for treating the skin lesion being positioned at epidermis in photodynamic therapy (PDT).Wavelength blue-violet 410nm has removing infectious effect, prevention and treatment wound infection and alleviating pain.Blue light wavelength main peak 425nm～475nm, so far the light source that phototherapy is best is remained, wavelength 450～460nm light can be able to be fully absorbed by bilirubin, and 470nm wavelength light substantially reduces methicillin-resistant staphylococcus aureus mean (MRSA), has suppression antibacterial effect.
When treating infected wound, it is proposed that adopting multiple coloured light combined illumination mode to improve curative effect, 400～490nm blue light sterilizes, remove and infect；600～690nm red light carries out shallow layer tissue's reparation, accelerates tissue healing process；780～970nm near infrared light carries out deep tissues reparation.
Owing to photostimulation effect is main relevant with wavelength, exposure dose and radiation modality, and the condition of coherent light is not necessarily.So in coherence, light intensity, wavelength, practicality and price etc., LED, with its inherent advantages, is entirely possible to and progressively substitutes current low-yield quasiconductor LASER phototherapy in following field of biology.
