Description
Technical field
This utility model relates to a kind of therapeutic equipments, especially a kind of antibacterial photosensitive therapeutic instrument.
Background technology
Generally, after experience natural disaster or serious disaster (such as fire, earthquake, war etc.), a large amount of large area skin wounds patient often occurs. And in serious large area skin wounds patient, have considerable patient to die from the destroyed antibacterial caused of the natural cover for defense resisting microorganism invasion as human body due to skin and invade and infect (patient of 50% to 70% dies from infection in serious Patients with Big Area Burn). Antibacterial and anti-inoculation technique currently for large area skin wounds patient skin surface is also only limited to use antibiosis usually to realize prevention and control. And this mode is due to deep burn, local vascular blocks, and whole body application antibiotic is difficult to reach the vegetative effect of Partial controll wound surface, and it is poor to depend merely on intravenous applications curative effect. Meanwhile, there is also the risk producing superbacteria because of abuse of antibiotics. Systemic application is antibacterial in wound early stage or biocide preparation is that realization early stage is antibacterial, it is prevented that the effective means that antibacterial attacks further. In recent years, the infection therapy that photodynamic effect kills multi-drug resistant bacteria is adopted to have been considered to the New Policy of a kind of very promising intractable bacterial infection disease for the treatment of. At present, existing considerable achievement in research confirm that various drug-resistant bacteria Mycodermas carry out by photodynamic therapy external and there is good effect in body sterilization. But, there is certain defect and weak point in the therapeutic equipment that current photodynamic therapy adopts, it is impossible to meets the demand of large area antibacterial bacteriostatic. It is in particular in: at present, the light source that the laser instrument of the different wave length of existence employing clinically and LED treat as light power antibacterial bacteriostatic. Owing to the directivity of conventional laser is better, the angle of divergence is less, therefore can only be irradiated in smaller scope. And in order to prevent hot injury patient caused because laser power density is too high, therefore the power of adopted laser instrument also reduces accordingly. This Photodynamic therapy is suitable only for the treatment of little area pathological changes: such as tumor, nevus flammeus etc. And in the treatment of large area skin wounds patient, this light source is only capable of sweeping the mode of photograph to solve the problem of irradiated area by doctor, so not only extends treatment time, significantly reduces therapeutic efficiency, and easily there is lighting dead angle, cause sterilization not thorough. And adopt the LED mode being irradiated bigger due to the angle of divergence of LED, and photo-thermal conversion efficiency is relatively low, although can solve the problem that the problem that irradiated area is less, but the homogeneity of irradiation area power density can not be ensured, again it cannot be guaranteed that irradiation area power density reaches the dosage of sterilizing at the appointed time. Owing to needed for total irradiation, power consumption is excessive, the demand of refrigeration system is also higher, therefore not yet go out to be now able to carry out the antibacterial LED of whole body light power at present and treat light source.
