Embodiment Construction

[0023] The preferred embodiments of the present invention are specifically described below with reference to the accompanying drawings, wherein the accompanying drawings constitute a part of the present application, and together with the embodiments of the present invention, are used to explain the principles of the present invention, but are not used to limit the scope of the present invention.

[0024] see figure 1 and figure 2 , a gas toxicity test device in this embodiment includes an exposure cavity 100 and a restraint assembly 200. The exposure cavity 100 can provide a breathing environment containing environmentally friendly insulating gas, and the test animals are bound in the restraint assembly 200 and exposed to exposure In the cavity 100, the toxicity of the environmentally friendly insulating gas to the test animals is studied.

[0025] The exposure chamber 100 includes a chamber body 110 containing an environmentally friendly insulating gas and a plurality of ac...

Abstract

The invention discloses a gas toxicity test device, and belongs to the technical field of toxicological research. The exposure cavity comprises a cavity body containing environment-friendly insulating gas and a plurality of access pipes, and one end of each access pipe is fixedly connected with the cavity body and communicated with an inner cavity of the cavity body; the restraining assembly comprises a containing cabin used for containing a test animal, a cabin cover and a push rod, the front end of the containing cabin is gradually shrunk and forms a conical part matched with the head of the test animal, the containing cabin is inserted into the connecting-in pipe, the conical part is communicated with an inner cavity of the cavity body, and the push rod is connected with the cabin cover. The chamber cover is connected with the rear end of the containing chamber in a sealed mode, the push rod is arranged in the containing chamber through the chamber cover, and the push rod can push the mouth and the nose of a test animal to enter the chamber body. The invention can eliminate the influence of the skin on the absorption effect of the test gas.

Description

technical field [0001] The invention relates to the technical field of toxicology research, in particular to a gas toxicity test device. Background technique [0002] New environmentally friendly insulating gases C4F7N, C5F10O, C6F12O, etc. are regarded as insulating media that can replace the traditional insulating gas SF6 because of their low global warming potential (GWP) and good insulating properties. However, there are still few data on the toxicity of new environmentally friendly insulating gases. How to conduct in-depth assessment of the inhalation toxicity of new environmentally friendly insulating gases and propose engineering application suggestions is still a current research hotspot. [0003] Most of the existing environmental protection insulating gas animal experimental devices are exposed to static exposure in the exposure room, and the test animals are completely placed in the exposure room, which cannot exclude the influence of the skin on the absorption of...
