Description
Technical field
The present invention 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 (as fire, earthquake, war etc.), often there is a large amount of large area skin wounds patient.And in serious large area skin wounds patient, have considerable patient die from due to skin as the natural cover for defense that human body resists microorganism invasion be destroyed caused antibacterial invade and infect (as in serious Patients with Big Area Burn 50% to 70% patient die from infection).At present, the antibacterial and anti-inoculation technique for large area skin wounds patient skin surface is also only only limitted 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, also there is the risk producing superbacteria because of abuse of antibiotics.Be realize antibacterial in early days to the antibacterial or biocide preparation of systemic application in early days in wound, prevent the effective means that antibacterial attacks further.In recent years, the infection therapy adopting photodynamic effect to kill multi-drug resistant bacteria has been considered to the New Policy of the intractable bacterial infection disease of a kind of very promising treatment.At present, existing considerable achievement in research confirms that photodynamic therapy is to carry out external of various drug-resistant bacteria Mycoderma with have good effect in body sterilization.But the therapeutic equipment that current photodynamic therapy adopts exists certain defect and weak point, the demand of large area antibacterial bacteriostatic cannot be met.Be in particular in: at present, there is the light source adopting the laser instrument of different wave length and LED to treat as light power antibacterial bacteriostatic clinically.Because 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 because laser power density is too high to the hot injury that patient causes, therefore the power of adopted laser instrument also reduces accordingly.This Photodynamic therapy is only only applicable to the treatment of small size pathological changes: as tumor, nevus flammeus etc.And in the treatment of large area skin wounds patient, the mode that this light source only can sweep photograph by doctor solves the problem of irradiated area, so not only extends treatment time, significantly reduces therapeutic efficiency, and easily there is lighting dead angle, cause sterilization not thorough.And the mode adopting LED to carry out irradiating due to the angle of divergence of LED larger, and photo-thermal conversion efficiency is lower, although the problem that irradiated area is less can be solved, but the homogeneity of irradiation area power density can not be ensured, can not ensure that again irradiation area power density reaches the dosage of sterilizing at the appointed time.Needed for total irradiation, power consumption is excessive, also higher to the demand of refrigeration system, therefore not yet occurs that can carry out the antibacterial LED of whole body light power treats light source at present.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of antibacterial photosensitive therapeutic instrument, can be effective to the surface disinfection antiinflammatory process after large area skin wounds (as fester, burn, scald etc.).
For solving the problems of the technologies described above, technical scheme of the present invention is:

Preferably, above-mentioned antibacterial photosensitive therapeutic instrument, also comprise between optical bracket and isolation, between described isolation, top is fixed with optical bracket, described beam expanding lens, scanning galvanometer, infrared thermoviewer and photographic head are by being fixedly connected with between this optical bracket with isolation, and described therapeutic bed is arranged in isolation.
Preferably, above-mentioned antibacterial photosensitive therapeutic instrument, purposes between described isolation is that the laser preventing from scattering out exposes to medical worker's eyes thus cause unnecessary damage around, both can adopt sliding door type structure between this isolation, tent can be adopted again to form to facilitate medical worker to carry out emergency aid and treatment in the wild.
Preferably, above-mentioned antibacterial photosensitive therapeutic instrument, described therapeutic bed can adopt driven type push-and-pull patient to enter between isolation, also can adopt wheeled stretchers or general surgery bed time urgent.
Above-mentioned antibacterial photosensitive therapeutic instrument carries out the implementation method of the antibacterial photosensitive treatment of large area, average power density is adopted to reach the large area hot spot of optical dynamic therapy demand, photosensitive drug is coordinated to realize damaged skin surface disinfection and promote wound healing, its large area hot spot utilizes scanning galvanometer to scan fast to realize, and concrete steps are as follows:
(1) monitor message that the patient affected part temperature field information that collects of infrared thermoviewer and photographic head transmit uploads on host computer, and display strictly according to the facts on a monitor;
(2) host computer is by setting irradiation area and monitoring, by high power laser light source drive current, Output of laser to beam expanding lens, after beam expanding lens expands, reach scanning galvanometer, by scanning galvanometer, the treatment of hot spot antibacterial bacteriostatic is carried out to patient treatment district;
(3) photographic head is after (to 635nm optical band) filtering, can observe the irradiated situation of patient by watch-dog.
Preferably, above-mentioned antibacterial photosensitive therapeutic instrument carries out the implementation method of the antibacterial photosensitive treatment of large area, host computer is monitored irradiation area and is referred to and raise monitor irradiating the temperature caused in described step (2): when the region of patient local is increased on secure threshold, and host computer is by controlling sweeping to show up and amassing to prevent secondary damage of (635nm) high power laser light source regulating power and gated sweep galvanometer; And when temperature sharply rises or machine there is fault; host computer by control high power laser light source close and on scanning galvanometer over cap close (when accident appears in scanning galvanometer; over cap automatically closes under the effect of electromagnetic valve, prevents from continuing photodamaged human skin).
The invention has the beneficial effects as follows:
Above-mentioned antibacterial photosensitive therapeutic instrument, that irradiated area is controlled, the antibacterial photosensitive therapeutic instrument of large area safely and effectively that Output of laser energy density is controlled, the surface disinfection antiinflammatory process after large area skin wounds (as fester, burn, scald etc.) can be realized within a short period of time, be applicable to the emergency treatment of a large amount of the wounded after burst accident and disaster; And before outputting to scanning galvanometer, have passed through expanding of beam expanding lens due to laser beam, therefore its to irradiate hot spot comparatively large, output power density maximum is lower, and temperature rise speed is relatively slow, and safety promotes greatly.
