Product Description

Chronic obstructive pulmonary disease (COPD) is a common chronic respiratory disease with high morbidity and mortality, which seriously threatens human health. Establishing an animal model consistent with the development and pathological changes of clinical patients is the basis for studying the pathogenesis and treatment of COPD.

The animal smoking modeling system is an automatic closed COPD modeling device, which can automatically generate cigarette smoke so that animals can continuously inhale it. It is suitable for establishing COPD models of mice, rats and guinea pigs. The frequency of smoking and the amount of smoke can be controlled, and the amount of smoke and environmental indicators in the fumigation chamber can be monitored in real time. The system has a high degree of automation and reliable performance, and can complete models with better consistency in one stop.

Features

· Preloaded cigarettes: A large number of cigarettes can be preloaded at one time, reducing frequent manual operations

· Burn one cigarette at a time, automatic continuous smoking

· Strong cigarette butt, using aviation thermal insulation material, stable and reliable

· It has the function of separating mainstream flue gas and side flow flue gas

· Maximum burning time per cigarette: 60 seconds

· With a flue gas flow meter, the flow rate of the incoming flue gas can be adjusted, and the flow range is 0-5L/min

· Automate smoking and establish standard smoking patterns

· With manual cigarette lighting mode and automatic mode. In manual mode, cigarette lighting can be triggered by on-screen buttons, and the cigarette position can be manually controlled. Automatic mode can realize fully automatic cigarette loading and lighting process

· The modeling process is completed automatically without supervision, automatic smoke intake - automatic smoke lighting - automatic smoke input into the fumigation cabin - real-time monitoring of the environment in the cabin - exhaust gas adsorption and exhaust. After clicking one, the next one will be loaded automatically

· Controlled by 10-inch touch screen, with dynamic curve of environment and smoke indicators.

· The fumigation exposure chamber is made of transparent material for easy observation

· Distributed porous smoke intake, with fans on each floor, so that the smoke is evenly distributed in the fumigation chamber

· Sensor chamber monitors chamber temperature, humidity, oxygen, carbon dioxide, carbon monoxide, pressure. Optional installation of smoke concentration detector

· Large-capacity cigarette butt canister, easy to dismantle and easily isolate the smoke inlet chamber and the combustion chamber, to prevent the pollution of the experimental environment due to the escape of flue gas

· Unique design structure, ease the clogging of e-liquid, easy to clean
