Rapid phototoxicity experiment cage for small animals

Abstract

The invention provides a rapid phototoxicity experiment cage for small animals. The rapid phototoxicity experiment cage comprises a front vertical plate, a rear vertical plate, a left side vertical plate and a right side vertical plate mounted on a guard bottom plate, wherein fixed grooves locked and fixed with spring brackets on a rapid animal phototoxicity experiment instrument are formed in thefront vertical plate and the rear vertical plate; breathing pores are formed in the lower part of the front vertical plate; a neck fixing clip on the front part of the guard bottom plate is capable of fixedly clamping the neck of a small animal; a protective curtain plate is arranged on the right side vertical plate by virtue of a curtain plate hinge; the protective curtain plate can be locked bythe left side vertical plate provided with a side plate bolt; four rectangular exposure holes are formed in the parts, which are positioned at the back of the small animal, of the protective curtainplate, so that the back partially receives UV exposure irradiation during the phototoxicity experiment, the experimental cage is taken out from the rapid animal phototoxicity experiment instrument after the experiment is completed, and a curtain plate fastener is lifted upwards, and the protective curtain plate is opened to take out the experimental small animal. The rapid phototoxicity experimentcage disclosed by the invention has the beneficial effects that according to the experiment cage, the small animals can be conveniently, rapidly and safely taken and put as well as protected, and necessary conditions are provided for completing the small animal phototoxicity rapid experiment.

Description

technical field [0001] The invention relates to a protective cage for rapid phototoxicity experiments of small animals. Background technique [0002] People are exposed to various chemical substances in their lives, especially daily chemicals or additives in articles. These chemicals have the possibility of causing damage to the human body under the condition of sunlight exposure, which is manifested as erythema and edema followed by pigmentation and desquamation of the skin within minutes or hours after exposure to sunlight. This requires a phototoxicity test for such chemicals; the small animal cages used in the phototoxicity experiments used to be simple in structure, and generally adopt a cylindrical structure with a closed front end, and small animals are taken and placed from the cage. It is not easy to operate and unsafe, and it is easy to injure the operator; and the neck of the small animal is not fixed, it will move independently, so the back part of the small ani...

Problems solved by technology

This requires a phototoxicity test for such chemicals; the small animal cage used in the phototoxicity test was originally constructed with a simple structure, generally a cylindrical structure with a closed front end, and small animals are taken and placed from the cage. It is not easy to operate and unsafe, and it is easy to injure the operator; and the neck of the small animal is not fixed, it will move independently, so the back part of the small animal irradiated by phototoxicity can move , resulting in inaccurate experimental results; open a large window on the upper part of the cage, and then artificially cover the parts that do not need to be exposed during the experiment, which complicates the experimental process and affects the experimental results; in order to expose small animals to ultraviolet light and phototoxicity In the experiment, it is convenient, fast and safe to complete the fixation and protection of experimental animals. It is an inevitable and urgent need to develop a small animal rapid phototoxicity experiment cage.
