breathing tube is fixedly installed on the top of the humidifier in a communicating mode, the outer surface of the
tail end of the
breathing tube is sleeved with a heat preservation wrapping pad, and a circulating heat preservation tube is fixedly arranged in the heat preservation wrapping pad. According to the breathing
machine for the breathing and critical
disease medicine department, an additional detachable constant-temperature heating wrapping pad is additionally arranged on existing breathing machine equipment, the
tail end of a
breathing tube can be wrapped, gas about to be inhaled by a patient is subjected to secondary heating constant temperature, the temperature of the
breathing gas is fully ensured, and the comfort of the breathing machine in the using process is improved; and the condition that the gas temperature is reduced due to the length of the
breathing tube is effectively avoided.
