Rotating disc type animal phototoxicity rapid tester

Abstract

The invention provides a turntable type animal phototoxicity rapid test apparatus, which includes a light cabin and a rotating disc installed on a fixed platform equipped with a movable support assembly, and there are several springs on the rotating disc whose speed is controlled by a stepping motor The bracket can fix the tested rat cage with experimental animals. When the tested rat cage moves to the light cabin, it can automatically open and close the cabin entry valve and the cabin exit valve. The UV light source component in the light cabin emits 365nm light with a single wavelength The UVA light source is used to conduct phototoxicity irradiation experiments on experimental animals. Soft curtains are installed around the bottom of the light cabin to ensure the purity of UVA light source and the accuracy of light intensity during the experiment. In the experiment, a computer controller controls and records the process and results of various tests, etc. Parameters or output to the printer to print the experiment report. The beneficial effect of the invention is that the phototoxicity irradiation experiment of small animals can be quickly and automatically completed. It can automatically control the light intensity and irradiation time required by this type of test, the stray light interference is small, the experimental efficiency is improved, and the experimental data is accurate and reliable.

Description

technical field [0001] The invention relates to a turntable type rapid tester for phototoxicity of animals. Background technique [0002] People are exposed to various chemical substances in their lives, especially daily chemicals or additives in articles. These chemical substances have the possibility of causing harm to the human body under the condition of sunlight exposure, which is manifested as erythema and edema followed by pigmentation and peeling of the skin within minutes or hours after exposure to sunlight, which requires the inspection of such chemicals Phototoxicity test detection: observe whether the skin of the tested animals has thick, red, swollen, macule, blisters and other adverse reactions after being irradiated with a certain dose of UVA light, and compare and determine whether the tested substance is phototoxic to animals according to the relevant regulations. It is deduced whether it may cause phototoxicity damage to humans; the previous phototoxicity ...
