Humidification chamber

A humidification system for respiratory or surgical humidification, comprising:

• a humidifier base unit comprising a heater plate;
• a first humidification chamber configured to be engageable with the humidifier base unit in thermal contact with the heater plate;
• and
• a second humidification chamber configured to be engageable with the humidifier base unit in thermal contact with the heater plate;
• wherein the first humidification chamber and the second humidification chamber differ structurally, and a thermal capacity of the second humidification chamber is substantially equivalent to a thermal capacity of the first humidification chamber.

A humidification system for respiratory or surgical humidification, comprising:

• a humidifier base unit comprising a heater plate;
• a first humidification chamber configured to be engageable with the humidifier base unit in thermal contact with the heater plate;
• and
• a second humidification chamber configured to be engageable with the humidifier base unit in thermal contact with the heater plate;
• wherein the first humidification chamber and the second humidification chamber differ structurally, and the second humidification chamber is configured to be substitutable for the first humidification chamber without adjusting a parameter or algorithm of the humidifier base unit.

A humidification chamber for respiratory or surgical humidification, the humidification chamber comprising:

• a hollow body, the hollow body comprising an inlet port and an outlet port;
• a heat conductive body configured to be removably attached to the hollow body, the heat conductive body comprising a contacting wall;
• and
• a surround, the surround integral with, attached to, or attachable with the heat conductive body, and comprising a removal feature;
• wherein the hollow body and the heat conductive body are configured to at least in part define a chamber configured to contain a volume of water, in use.

A humidification chamber for use with a humidifier base unit to humidify a flow of medical gases for respiratory therapy or surgical insufflation, the humidification chamber comprising:

• a hollow body comprising:
• an inlet port for ingress of the flow of medical gases into the humidification chamber, in use;
• and
• an outlet port for egress of the flow of medical gases from the humidification chamber, in use;
• a heat conductive body, the hollow body and the heat conductive body in combination configured to form, at least in part, a chamber configured to receive a volume of liquid with a headspace providing a passage for the flow of medical gases from the inlet port to the outlet port;
• and
• a sealing element configured to provide a seal between the hollow body and the heat conductive body.

A humidifier system configured to humidify a flow of medical gases for respiratory therapy or surgical insufflation, the humidifier system comprising:

• a base unit comprising a heater plate configured to generate heat, in use;
• a disposable humidification chamber configured to be removably received by the base unit in thermal contact with the heater plate;
• and
• a reusable humidification chamber configured to be removably received by the base unit in thermal contact with the heater plate,
• wherein each of the disposable humidification chamber and the reusable humidification chamber comprise a heat conductive body with a thermal capacity between about 16 J/K and 27 J/K, between about 19 J/K and 24 J/K, between about 20 J/K and 22 J/K, or about 21 J/K.
