Conveying belt type animal phototoxicity rapid tester

Abstract

The invention provides a conveying belt type animal phototoxicity rapid tester. The conveying belt type animal phototoxicity rapid tester comprises an illumination cabin and a conveying toothed belt which are mounted on a fixed platform provided with a movable supporting assembly, tested mouse cages for experimental animals can be fixedly mounted on a plurality of spring supports on the conveyingtoothed belt of which the rotating speed is controlled by a stepping motor, when the tested mouse cages move to the illumination cabin, an entering valve and an exiting valve can be automatically opened and closed, a UV light source assembly in the illumination cabin emits 365 nm of a UVA light source with single wavelength and proper strength to carry out phototoxicity illumination experiment onthe experimental animals, soft sun blinds are mounted on the periphery of the bottom of the illumination cabin to ensure UVA light source purity and light strength accuracy during experiment, parameters such as processes and results of various tests or experimental reports printed by a printer are controlled and recorded by a computer controller in the experiment. The conveying belt type animal phototoxicity rapid tester has the beneficial effects that a phototoxicity illumination experiment for small animals can be rapidly and automatically finished. Light intensity and irradiation time whichare required for the tests can be controlled automatically, stray light interference is small, the experimental efficiency is improved, and experimental data are accurate and reliable.

Description

technical field [0001] The invention relates to a conveyor belt 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 phototoxic...

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 identification test equipment is relatively simple, and only one or a few test animals can be used for each test. When a large number of phototoxicity tests need to be done, batches are replaced The tested mouse cages with the animals installed need to be replaced batch by batch, which is time-consuming and discontinuous, and the detection efficiency is low. Therefore, a kind of animal phototoxicity detection system can be developed that can place and remove the tested mouse cages at any time, and automatically and continuously detect them. Rapid tester becomes imperative
