Embodiment Construction

[0018] The whole cigarette smoke exposure culture device of the present invention consists of a cigarette full smoke exposure bottle 6 with a smoke outlet 3 on it, and a smoke introduction pipe plug 7 whose lower half is placed in the cigarette full smoke exposure bottle 6 Most of them are composed; wherein: the flue gas introduction pipe plug 7 is composed of a flue gas inlet 1, a mixed air inlet 2, a flue gas and air mixing chamber 4, and a diluted flue gas delivery path 5. The device is blown from glass tubes used in experiments according to traditional techniques, and other components connected to it are purchased from the market.

[0019] The connection and use of the cigarette full smoke exposure device of the present invention and the linear smoking machine are as follows:

[0020] 1. Sterilize the full smoke exposure bottle 6 and the smoke introduction pipe plug 7 in an autoclave for standby;

[0021] 2. Put 10ml of the reaction cell or bacterial culture solution into...

Abstract

The invention relates to a device for exposing cigarette mainstream smoke, and belongs to the technical field of gas exposure culture. The device comprises two parts of a cigarette mainstream smoke exposure bottle (6) provided with a smoke outlet (3), and a smoke guiding tube plug (7) of which the lower half is arranged in the cigarette mainstream smoke exposure bottle (6), wherein the smoke guiding tube plug (7) consists of a smoke inlet (1), a mixed air inlet (2), a smoke and air mixing chamber (4), and a diluted smoke conveying passage (5). Compared with the prior arts, the present device has the advantages of simple structure, convenient operation, reduction of experiment difficulty, low cost, and convenience of connection with a linear type smoking machine for realizing cigarette mainstream smoke exposure of bacteria or cells.

Description

Technical field: [0001] The invention relates to a device for exposing whole cigarette smoke, which belongs to the technical field of gas poisoning culture. Background technique: [0002] Cigarette smoke is an aerosol composed of thousands of chemical substances. These compounds can produce countless qualitative and quantitative changes through chemical reactions in a short period of time when the smoke is produced [1], many of which are harmful to cells or the human body. Has a certain toxic effect. In vitro toxicology research methods evaluate the potential impact of experimental subjects on the human body by measuring the potential harm or damage of toxic substances to cells or DNA in a short period of time [2]. The measurement objects include additives, tobacco extracts, smoke condensate, smoke gas phase and whole smoke. At present, the in vitro toxicology research of cigarette smoke mainly focuses on the genotoxicity and cytotoxicity test of cigarette smoke, and these...
