Antibacterial photosensitive therapeutic apparatus

Abstract

The invention provides an antibacterial photosensitive therapeutic apparatus, which comprises a high-power laser light source, a beam expander, a scanning galvanometer, an infrared imaging apparatus, a treatment table, a camera, a monitor and an upper computer, wherein the beam expander, the scanning galvanometer and the infrared imaging apparatus are arranged above the treatment table; the upper computer is respectively in controlled connection to the high-power laser light source, the infrared imaging apparatus, the camera and the monitor by virtue of lines; meanwhile, the upper computer is in controlled connection to the scanning galvanometer by virtue of a line through a scanning galvanometer controller; and the high-power laser light source is connected to the scanning galvanometer by virtue of a line through the beam expander. The therapeutic apparatus is controllable in irradiation area, and the large-area antibacterial photosensitive therapeutic apparatus, which is controllable in output laser energy density and is safe and effective, is capable of completing surface sterilizing and inflammation-diminishing treatment on injured large-area skin within a relatively short time; and the therapeutic apparatus is suitable for the emergency treatment of a great amount of wounded persons in the case of sudden accidents and major disasters.

Description

technical field [0001] The invention relates to a treatment instrument, in particular to an antibacterial photosensitive treatment instrument. Background technique [0002] Generally, after natural disasters or severe disasters (such as fires, earthquakes, wars, etc.), there will often be a large number of patients with large areas of skin damage. In patients with severe large-area skin injuries, a considerable number of patients died of bacterial invasion and infection caused by the destruction of the skin as a natural barrier against microbial invasion (such as 50% to 70% in patients with severe large-area burns) patients died from infection). At present, antibacterial and anti-infection technologies for the skin surface of patients with large-scale skin damage are limited to the use of antibiotics for prevention and control. However, due to deep burns and local vascular occlusion, it is difficult for systemic application of antibiotics to achieve local control of bacter...

AI Technical Summary

Problems solved by technology

Because the traditional laser has good directionality and small divergence angle, it can only be irradiated to a relatively small range.

In order to prevent thermal damage to the patient due to excessive laser power density, the power of the laser used is also reduced accordingly.

This photodynamic therapy is only suitable for the treatment of small-area lesions: such as tumors, port wine stains, etc.

However, in the treatment of patients with large area of ​​skin damage, this light source can only solve the problem of the irradiation area by the way of scanning by doctors, which not only prolongs the treatment time, greatly reduces the treatment efficiency, but also tends to have blind spots in the irradiation, resulting in Incomplete sterilization

However, due to the large divergence angle of the LED and the low photothermal conversion efficiency of the LED, although it can solve the problem of a small irradiation area, it can neither guarantee the uniformity of the power density of the irradiation area nor the irradiation area. The power density reaches the dose of sterilization and disinfection within the specified time

Due to the excessive power consumption required for whole body irradiation and the relatively high demand for refrigeration systems, there is no LED therapeutic light source that can perform whole body photodynamic bacteriostasis.
