1. A cannula fixation device, comprising:
a base, including a platform and having a first end and an opposite second end;
a subject-interface portion having an upper surface and a lower surface, the upper surface coupled to the base and the lower surface configured to be coupled to a subject; and
a clip assembly configured to retain a portion of a cannula, the clip assembly including a first end and an opposite second end, the clip assembly being moveably coupled to the base such that the clip assembly can be selectively positioned in a forwardmost position relative to the base in which the first end of the clip assembly is moved toward the first end of the base or a rearwardmost position relative to the base in which the second end of the clip assembly is moved toward the second end of the base,
wherein the first and second ends of the clip assembly are positioned between the first and second ends of the base when the clip assembly is in the forwardmost position, and
wherein the first and second ends of the clip assembly are positioned between the first and second ends of the base when the clip assembly is in the rearwardmost position;
wherein the clip assembly is configured to receive the portion of a cannula through an opening in an upper surface of the clip assembly and retain the cannula therein while the opening in the upper surface of the clip assembly remains open after receiving the portion of the cannula.
 
12. A cannula fixation device, comprising:
a subject-interface portion having an upper surface and a lower surface, the subject-interface portion being configured to be coupled to a subject;
a base configured to be coupled to the upper surface of the subject-interface portion, the base including a platform and an upper surface, the base including a first end and an opposite second end; and
a clip assembly configured to retain a portion of a cannula through an opening in an upper surface of the clip assembly, the clip assembly being moveably coupled to the base along an axis, the axis extending from the first end of the base to the second end of the base such that the clip assembly can be selectively positioned in a first position relative to the base and a second position relative to the base, the clip assembly comprising a pair of opposite, opposed, wing structures such that, when the wing structures are squeezed toward one another, the clip assembly is able to be slid between the first position and the second position;
wherein the clip assembly includes a first end and an opposite second end, the clip assembly extending along the axis, wherein both the first end of the clip assembly and the second end of the clip assembly are positioned between the first end of the base and the second end of the base in the first position;
wherein the clip assembly is configured to receive the portion of a cannula through an opening in an upper surface of the clip assembly and retain the cannula therein while the opening in the upper surface of the clip assembly remains open after receiving the portion of the cannula.
 
17. A cannula fixation device, comprising:
a subject-interface portion having an upper surface and a lower surface, the subject-interface portion being configured to be coupled to a subject;
a base configured to be coupled to the upper surface of the subject-interface portion, the base including a platform and an upper surface; and
a clip assembly configured to retain a portion of a cannula through an opening in an upper surface of the clip assembly, the clip assembly being moveably coupled to the base such that the clip assembly can be selectively positioned in a first position relative to the base and a second position relative to the base, the clip assembly comprising a pair of opposite, opposed, wing structures such that, when the wing structures are squeezed toward one another, the clip assembly is able to be slid between the first position and the second position;
the clip assembly including:
a lower wall having an upper surface and a lower surface, the lower surface being positioned adjacent to an upper surface of the base; and
the pair of opposite, opposed, wing structures extending from the upper surface of the lower wall, each wing structure of the pair of opposite, opposed wing structures comprising a first section extending upward from the upper surface of the base, wherein the first section of each of the wing structures of the pair of opposite, opposed wing structures and a portion of the upper surface of the lower wall form a cannula-retaining portion of the clip assembly;
wherein the clip assembly is configured to receive the portion of a cannula through an opening in an upper surface of the clip assembly and retain the cannula therein while the opening in the upper surface of the clip assembly remains open after receiving the portion of the cannula; and
wherein each first section includes a curve configured to correspond to an outer surface of the portion of the cannula, and wherein the clip assembly is configured such that, when the portion of the cannula is retained in the cannula-retaining portion, and when the wing structures are pushed downwards, the first sections move away from one another, thereby releasing the portion of the cannula.
