Abstract

An apparatus is provided. The apparatus includes: a humidification component configured for holding a water volume, the humidification component comprised entirely of a non-metallic material. The non-metallic material conducts heat to the water volume, the heat being received from a heating element.

Claims

1. An apparatus comprising:

a humidification component configured for retaining a water volume, said humidification component having a base portion comprising a non-metallic material transmissive to electromagnetic radiation, and a reflective surface within a portion of said humidification component; and

a base unit comprising a heating element, the heating element configured to transmit electromagnetic radiation to the humidification component using received electrical energy, and a transmissive sensor and a reflective sensor external to the humidification component;

wherein the humidification component is coupled to the base unit such that (i) the heating element transmits electromagnetic radiation from the base unit, through the non-metallic material of the base portion, and directly to the water volume, and (ii) said reflective surface directs transmitted electromagnetic radiation to the water volume, wherein the water volume is heated by absorbing the electromagnetic radiation, and

wherein said transmissive sensor detects the amount of electromagnetic radiation directed through said humidification component, and said reflective sensor detects the amount of electromagnetic radiation, directed by said reflective surface, within said humidification component.

2. The apparatus of claim 1, wherein said humidification component and said heating element are independent of each other.

3. The apparatus of claim 1, wherein said humidification component is comprised entirely of a polymer material.

4. The apparatus of claim 3, wherein said polymer material comprises cross-linked polyethylene.

5. The apparatus of claim 3, wherein said polymer material comprises polyphenylene sulfide.

6. The apparatus of claim 3, wherein said polymer material comprises polysulfone.

7. The apparatus of claim 3, wherein said polymer material comprises polycarbonate.

8. The apparatus of claim 3, wherein said polymer material comprises a thermally conductive polymer.

9. The apparatus of claim 1, wherein said humidification component is a blow molded humidification component.

10. The apparatus of claim 9, wherein said blow molded humidification component lacks joints and seals.

11. The apparatus of claim 1, wherein said humidification component is an injection molded humidification component.

12. The apparatus of claim 1, wherein said humidification component is disposable.

13. The apparatus of claim 1, wherein said humidification component is configured for transmitting light from an optical transmitter.

14. The apparatus of claim 1, wherein said humidification component is pre-filled with water prior to a first time use by a user.

15. A method for providing humidification in a respiratory system, said method comprising:

emitting electromagnetic radiation to a humidification component from a heating element disposed in a base unit, said base unit having a transmissive sensor and a reflective sensor external to the humidification component;

receiving, at a base portion of the humidification component comprising a non-metallic material transmissive to electromagnetic radiation, electromagnetic radiation transmitted from the heating element, said humidification component configured for retaining a water volume;

transmitting, through said non-metallic material of the base portion, electromagnetic radiation received at said humidification component into said water volume wherein said electromagnetic radiation is transferred directly from the heating element to the water volume such that the water volume is heated by absorbing the electromagnetic radiation;

directing, by a reflective surface within a portion of the humidification component, electromagnetic radiation to the water volume; and

detecting said electromagnetic radiation (i) directed through the humidification component by the transmissive sensor, and (ii) directed by the reflective surface within the humidification component by the reflective sensor.

16. The method of claim 15, wherein said humidification component and said heating element are independent of each other.

17. The method of claim 15, wherein said transmitting, comprises transferring said received electromagnetic radiation to said water volume by conduction of said received electromagnetic radiation through at least one wall of said humidification component.

18. The method of claim 15, wherein said transmitting, comprises conducting, by said non-metallic material, said received electromagnetic radiation through said humidification component into said water volume, wherein said water volume of said humidification component is pre-filled with water prior to a first time use by a user.
