Phototoxicity exposure experimental animal fixing and protecting device

Abstract

The invention provides a phototoxicity exposure experimental animal fixing and protecting device. The phototoxicity exposure experimental animal fixing and protecting device comprises a circular fixing frame which is arranged on a plane-shaped bottom plate and can fix experimental animals. An adjustable covering device and a side ejecting device are arranged on the circular fixing frame. A fixing shackle is arranged on the front side of the circular fixing frame and can clamp experimental animals. A top covering plate connected with the upper end of a front vertical plate at the front end of the bottom plate protects heads of experimental animals against phototoxic damage when conducting downward covering. A belly ejecting device is arranged at the bottom of the circular fixing frame and ejects back exposed epidermis of experimental animals so that the back exposed epidermis can not move when receiving phototoxicity exposure experiments. An excrement leakage opening located at excretory pores of experimental animals is located in the rear portion of the bottom plate. An excrement collector special for collecting excrement excreted by experimental animals is arranged below the excrement leakage opening. Four supporting leg frames are arranged at the four corners of the bottom plate and can adjust the height and the flatness. The phototoxicity exposure experimental animal fixing and protecting device has the advantages that the device which can conveniently, rapidly and safely complete experimental animal fixation and protection when phototoxicity exposure experiments are conducted is developed, and problems on this aspect are solved.

Description

technical field [0001] The invention relates to a fixed protection device for phototoxic exposure experimental animals. Background technique [0002] At present, in the fields of daily chemicals, new drug development, food and drug safety testing, skin pathology and other fields, the special needs of light allergy and disease-causing scientific research are increasingly paid attention to, especially some special light environments such as long-term work in ultraviolet radiation and strong light What kind of damage will be caused to the skin of personnel in the irradiated environment, as well as the protection method and effect research, etc. need to be proved by scientific experiments. At present, the common way to fix small animals in phototoxicity exposure experiments is to use ropes to fix the limbs of small animals.

[0002] At present, in the fields of daily chemicals, new drug development, food and drug safety testing, skin pathology and other fields, the special needs of light allergy and disease-causing scientific research are increasingly paid attention to, especially some special light environments such as long-term work in ultraviolet radiation and strong light What kind of damage will be caused to the skin of personnel in the irradiated environment, as well as the protection method and effect research, etc. need to be proved by scientific experiments. At present, the common way to fix small animals in phototoxicity exposure experiments is to use ropes to fix the limbs of small animals. Fix it on a flat plate, expose an area on the back and directly irradiate it with a specific exposure light, cover the unirradiated part with adhesive tape, then measure it with a light intensity measuring instrument and observe the effect of the experiment with the naked eye. One foot, it is both troublesome and not firm to operate, the small animal often breaks free in the middle of the experiment, causing the irradiated part to move and the experiment fails. The damage caused by phototoxicity affects the accuracy of the test results; and the small animals have to excrete at any time during the experiment. Without the collection device, the experimental environment will be polluted and the operator will also be harmed; therefore, a phototoxic exposure experiment was developed. Immobilization and protection of experimental animals can be completed conveniently, quickly and safely, and small animal excrement can be collected at any time without causing environmental pollution. The immobilization and protection device for experimental animals with phototoxic exposure has become an urgent need at present.
