A humidification system can include a heater base, a humidification chamber, and a breathing circuit. A cartridge can be removably coupled to the heater base. The cartridge can include various sensors, probes, sensor wire connectors, heater wire connectors, and/or other features. The cartridge can include features configured to mate with corresponding features on the humidification chamber and the heater base. The cartridge includes a memory, such as an EEPROM, or other suitable storage device. When the cartridge is installed on the heater base, the memory is electrically connected to a processor and/or memory of the heater base. Various models of cartridges can be produced for use with different humidification chambers, breathing circuits, and/or therapies. A connector can be configured to couple an inspiratory conduit to an outlet port of the humidification chamber. The connector can provide a pneumatic connection to the outlet port and an electrical connection to the cartridge.

A humidifier has a supply of water suspended on a pole above a patient which supplies water through a removable drop counter of magnetically actuated ball valve to a microporous tube mounted in but mechanically separated from a ventilating line between a ventilator and the patient. The water is heated in the microporous tube to create a vapor pressure sufficient to cause water vapor but substantially no liquid water to pass through the tube into the ventilating line. Electrically energized controls are provided to obviate maloperation and to maintain safe operating conditions including maintaining safe temperature conditions, and prevention of excess water entering the ventilation line by counting the drops of water passing through the bold valve, and closing the ball valve if the count rate is outside desired count rates and power or the monitoring equipment fails.
