The invention relates to a self-adaption 
continuous infusion apparatus. The self-adaption 
continuous infusion apparatus comprises an upper half part and a 
lower half part, and is characterized in that the upper half part is provided with a 
bottle plug puncture device (2) and a 
bottle plug puncture device protection cover, the upper end of the 
bottle plug puncture device (2) is used for 
puncturing through a bottle plug of a to-be-infused bottle, and the bottle plug puncture device protection cover is fixedly arranged on the bottle plug puncture device (2) to protect the bottle plug puncture device (2). In the self-adaption 
continuous infusion apparatus, the situations are avoided that infusion is automatically stopped after infusion is completed, the blood return phenomenon is caused when nurses do not attend on patients timely and the liquid level drops to a too low level, more seriously, gas enters the 
human body, which results in bad results like aeroembolism, or when multiple infusion bottles are infused continuously, if the liquid level is lower than the lower part of a Murphy's dropper, air exhaust needs to be conducted again or intravenous injection needs to be conducted again; meanwhile, to prevent the situation that the liquid level is lower than the Murphy's dropper, the nurses, patients and relatives need to conduct 
nursing in real time, which results in unnecessary tension and psychological burdens of the three parties, therefore, the psychological burden in seeking medical service can be sharply lowered through automatic stopping of infusion, and thus the comfort in seeking medical service is improved.
