Abstract

The invention discloses a photo-thermal and photo-power treatment device which comprises a closed treatment chamber as well as a laser, a heating plate, an optical system, a blood oxygen instrument, a thermal imaging system and an air purifier packaged in the treatment chamber, wherein the laser emits laser to provide a light source to a treated body through the optical system, the optical system is used for controlling the spot size of the laser to control the power density of the light source, the heating plate is used for heating the treatment chamber to maintain the temperature of the treatment body, the blood oxygen instrument is used for monitoring the blood oxygen concentration change of the treatment body, the thermal imaging system is used for detecting the local or overall temperature of the treatment body, the air purifier is used for purifying air in the treatment chamber, and the treatment chamber is further provided with a ventilating hole for inputting oxygen or anesthetics to the treatment chamber. The device disclosed by the invention combines photo-thermal and photo-power treatments, and can realize photo-thermal and / or photo-power treatment for small animals or cells in a culture plate.

Description

technical field [0001] The invention relates to a device for physical therapy, in particular to a photothermal and photodynamic therapy device for treating small animal tumors or cells in culture plates. Background technique [0002] Traditional surgical resection, chemotherapy, radiotherapy or biological therapy have made extraordinary achievements in tumor treatment, but their toxic side effects, multidrug resistance and other problems are still difficult to overcome. In recent years, photothermal and photodynamic therapy of near-infrared light-activated nanomaterials that penetrate the skin have been increasingly favored due to their advantages such as non-invasive, non-toxic, targeted, and efficient. Photothermal therapy refers to using the thermal effect of various heat sources to heat the tumor area or the whole body to an effective temperature for treatment and maintain it for a certain period of time. Using the difference in temperature tolerance between normal tissu...
