Description

Technical Field

[0001] The utility model belongs to the technical field of gas chamber, and particularly relates to a placing rack for a static gas chamber. Background Art

[0002] In a laboratory, the gas poisoning methods usually include static gas poisoning and dynamic gas poisoning. Static gas poisoning means placing experimental animals in a closed container with a certain volume, adding a certain amount of volatile liquid test chemical or a certain volume of gaseous test chemical, and forming an air environment containing the required concentration of test chemical in the closed container to poison the animals. Dynamic gas poisoning means placing experimental animals in a gas chamber with air flow. The gas chamber is equipped with a power system for supplementing fresh air and discharging the mixed gas of test chemical, and a gas distribution system for quantitatively supplementing the test chemical at any time. Although dynamic gas poisoning is more in line with the actual situation, the device is complex, expensive, consumes a large amount of test chemical, and is easy to pollute the operation room environment, so it is rarely used in general laboratories. Static gas poisoning equipment is inexpensive, easy to build, convenient to operate, and consumes less test chemical, especially suitable for teaching experiments and general small animal gas poisoning tests.

[0003] Currently, the general static gas poisoning equipment places the test chemical at a fixed position and then sets a fan to blow the test chemical to achieve the diffusion of the poison. However, this method has a slow and uneven diffusion speed of the poison, resulting in a large toxicity in some areas and a small toxicity in some areas, affecting the accuracy of the test results.

Detailed Description of the Embodiments

[0018] Regarding the foregoing and other technical contents, features and effects of the present utility model, they will be clearly presented in the following detailed description in conjunction with the Figures 1-4 embodiments. The structural contents mentioned in the following embodiments are all with reference to the drawings of the specification.

[0019] The following will describe the exemplary embodiments of the present utility model with reference to the drawings.

[0020] Example 1. A rack for a static poisoning cabinet, comprising a cabinet body 1, a closing door 2 is detachably connected to the cabinet body 1, a plurality of groups of drainage pipes 3 are fixedly connected to the cabinet body 1 at intervals along the circumferential direction, exhaust holes 4 are provided on each of the plurality of groups of drainage pipes 3, the plurality of groups of drainage pipes 3 are connected to a suspended box 5 corresponding to the closing door 2, the suspended box 5 is communicated with the drainage pipes 3, a cover plate 6 is provided at the upper end of the suspended box 5, a rack 7 placed in the suspended box 5 is provided at the bottom of the cover plate 6, a placement groove 8 is provided on the rack 7, a medicine pool body 9 is provided in the placement groove 8, a fan 10 corresponding to the medicine pool body 9 is provided on the cover plate 6, and a sewage discharge pipe 11 is provided at the bottom of the cabinet body 1; an installation groove 15 matched with the fan 10 is provided on the cover plate 6, an installation plate 16 is provided on the installation groove 15, and a plurality of groups of ventilation holes 17 are provided at intervals on both the installation groove 15 and the installation plate 16.

[0021] When in use, by opening the closing door 2, the cover plate 6, the rack 7 and the medicine pool body 9 are moved out of the suspended box 5, chemical drugs are put into the medicine pool body 9, the medicine pool body 9 is placed in the placement groove 8 provided on the rack 7, then the cover plate 6, the rack 7 and the medicine pool body 9 are put into the suspended box 5, magnets can be arranged between the suspended box 5 and the cover plate 6 for magnetic attraction to further improve the stability between the suspended box 5 and the cover plate 6.
