Description

Technical Field

[0001] This utility model relates to the field of photodynamic therapy devices, specifically an adjustable photodynamic therapy device. Background Technology

[0002] Photodynamic therapy (PDT) is a new technology that utilizes the photodynamic effect for disease diagnosis and treatment. Its mechanism of action is based on the photodynamic effect itself. It is a photosensitization reaction involving oxygen molecules and accompanying biological effects. The treatment process utilizes laser irradiation of a specific wavelength to excite the photosensitizer absorbed by the tissue. The excited photosensitizer then transfers energy to the surrounding oxygen, generating highly reactive singlet oxygen. This singlet oxygen reacts with adjacent biomolecules, producing cytotoxic effects that lead to cell damage and even death. Currently, there is an adjustable PDT device, such as... Figure 1 As shown, the device includes a base 1, with universal wheels 11 at the bottom of the base 1 having a limiting function. A main unit 2 is fixed on the base 1. A control panel 21 is located on the right side of the main unit 2. A crossbeam 3 extending to the left is located on the top of the main unit 2. A vertical sleeve 4 is located on the lower side of the left end of the crossbeam 3. An n-shaped frame 5 with an adjustable angle is located in the sleeve 4. A treatment head 6 with an adjustable angle is located inside the n-shaped frame 5.

[0003] The aforementioned adjustable photodynamic therapy device can treat affected areas. However, a defect was discovered during use: the treatment head 6 is located relatively far outward at the left end of the crossbeam 3, making it susceptible to damage from pedestrians when not in use. Furthermore, the adjustable photodynamic therapy device lacks a protective structure to accommodate the treatment head 6. Utility Model Content
