Abstract:
OBJECTIVE To investigate the terminal bacterial pollution of hospital central oxygen supply system and the sanitizing effect of MX-1 disinfector. METHODS Timing many spot samples of terminal oxygen supply equipment (oxygen flowmeter, humid bottle, oxygen pipe) were quantified and cultivated through 24 hours continue supply. RESULTS Five cases of timing many spot samples testified that there were no bacteria oxygen pollution in the pipe oxygen supply in the Department of Respiratory Disease, the Second Affiliated Hospital of Dalian Medical University, and that there were no bacteria pollution in the terminal oxygen supply equipments if they were sterilized strictly, but there would be severe bacteria pollution if they were not sterilized strictly. This test found that lid of humid bottle and lapis were the main source of bacteria pollution. Connection with MX-1 disinfector in the terminal can avoid bacteria pollution. CONCLUSIONS Severe bacteria pollution will happen if the oxygen supply equipments aren't sterilized strictly; connection with MX-1 disinfector in the terminal can avoid bacteria pollution and ensure oxygen for cleanliness and safety.
