Description

TECHNICAL FIELD

[0001] The utility model relates to the field of drug photodegradation research, especially relates to a drug photodegradation device. BACKGROUND

[0002] In the field of drug photodegradation research, the traditional photodegradation experimental device has many shortcomings. On the one hand, the sealing of the traditional device is poor, and it cannot provide a stable experimental environment for the drug solution. External factors can easily interfere with the experimental results. Moreover, it is difficult to effectively observe the drug solution during the experiment, and the experimental progress cannot be monitored in real time.

[0003] In terms of light source setting, the traditional device often has a single light source, which cannot meet the needs of different drugs for multiple light sources and different illuminance. There is a lack of precise control means for the light source, and the parameters such as the illuminance of cold light and the wavelength of ultraviolet light cannot be flexibly adjusted, making it difficult to adapt to photodegradation research under different experimental conditions.

[0004] For light uniformity, the traditional device usually cannot make the drug solution receive uniform light. There is no effective measure to improve the light irradiation surface, resulting in too strong or too weak light in some areas of the drug solution, affecting the accuracy and reliability of the experiment. At the same time, the control of the light time of the traditional device is not accurate enough, and it cannot meet the strict experimental requirements.

[0005] In terms of heat dissipation, most traditional photodegradation experimental devices do not have effective heat dissipation measures. The heat generated by electrical equipment during operation is easily accumulated in the experimental box, which has an adverse effect on the drug solution and thus interferes with the experimental results.

[0006] In addition, the traditional device has shortcomings in improving experimental accuracy. It cannot fully mix and evenly distribute the drug solution, resulting in inconsistent photodegradation in different areas of the solution. Moreover, the fixation method of the test tube is not stable enough, and it is easy to slip off during the experiment, affecting the smooth progress of the experiment.

[0007] In summary, in order to overcome the shortcomings of the traditional drug photodegradation experimental device, a new type of drug photodegradation device is urgently needed to improve the sealing of the experiment, the diversity and controllability of the light source, the uniformity of the light, the heat dissipation effect, and the accuracy of the experiment.
