[0022] Examples:
[0023] Before using the multi-point simultaneous exposure rapid phototoxicity test equipment of the present invention, the experimental animal 11 and the test substance should be prepared first, and 18-24 hours before the phototoxicity test according to the relevant standards of skin phototoxicity test, Dehair the skin on both sides of the animal's spine. The test site must be intact and free from damage or abnormality. Prepare 4 depilatory areas on the back of the experimental animal. Each depilatory area is about 2×2cm, and then irradiate area A with light. 22 and light irradiation B area 21 smear the test object, 30 minutes later, cover the light irradiation B area 21 and light irradiation D area 20 with aluminum foil, and place the prepared experimental animal 11 on the light-absorbing surface operating table 12 according to the test animal 11 Height Adjust the height of the light path box 19 up and down by adjusting the knob on the height adjuster 15, adju...
