Abstract

A pressure support system that comprises a patient circuit, a docking assembly, and a tank. The patient circuit delivers a pressurized flow of breathable gas to a patient. The docking assembly has an inlet and an outlet that is adapted to receive the pressurized flow of breathable gas, and is also adapted to be connected with the patient circuit. The tank is constructed and arranged to be removably connected with the docking assembly, and enables the pressurized flow of breathable gas to pass therethrough. The tank is also adapted to contain a liquid such that a humidity level of the pressurized flow of breathable gas is elevated as the pressurized flow of breathable gas passes therethrough.

Claims

1. An electronic modular accessory that selectively interfaces with a gas flow generating system that generates a pressurized flow of breathable gas for delivery to a patient, the modular accessory comprising:

a delivery system interface disposed at a first end of the modular accessory that removably connects to an accessory interface of the gas flow generating system to place the modular accessory in electronic communication with the gas flow generating system such that if the delivery system interface is connected to the accessory interface, information can be transferred electronically from the modular accessory to a control unit of the gas flow generating system and from the control unit of the gas flow generating system to the modular accessory;

a communication unit that is configured to output the information transferred electronically from the control unit of the gas flow generating system to the modular accessory, wherein the gas flow generating system and modular accessory are configured to be in electronic communication with a humidifier control interface configured to cause elevation of a humidity level of the pressurized flow of breathable gas, wherein the information transferred electronically from the gas flow generating system to the modular accessory includes the humidity level, and wherein the information electronically output from the communication unit of the modular accessory includes the humidity level; and

a modular accessory housing including at least one stop surface disposed at a second end of the modular accessory, the second end opposite the first end, the at least one stop surface configured to prevent the modular accessory from being inserted into a modular accessory port more than a predetermined distance.

2. The modular accessory of claim 1, wherein the communication unit comprises a connection to a network, and information transferred from the gas flow generating system to the modular accessory is output from the communication unit to the network.

3. The modular accessory of claim 1, wherein the communication unit comprises a wireless transmitter, and information transferred from the gas flow generating system to the modular accessory is output from the communication unit by wireless transmission.

4. The modular accessory of claim 1, wherein the communication unit comprises a writeable electronic media drive, and information transferred from the gas flow generating system of the modular accessory is output from the communication unit by writing the information to a writeable electronic media.

5. The modular accessory of claim 1, wherein the information transmitted from the modular accessory to the gas flow generating system comprises information related to a communication unit type of the communication unit.

6. The modular accessory of claim 1, wherein the communication unit enables information to be input to the modular accessory from a source other than the gas flow generating system, and the communication unit transmits the information to the gas flow generating system.

7. The modular accessory of claim 1, wherein the information output to the communication unit includes malfunction indicating information obtained by control unit of the gas flow generation system.

8. The modular accessory of claim 1, wherein the at least one stop surface comprises a first overhang formed at a first side of the modular accessory and a second overhang formed at a second side, opposite the first side.
