1. An apparatus in fluid communication with a first source of pressurized fluid and a second source of pressurized fluid, the apparatus comprising:
- a pressure reduction section;
a unitary body member having a first portion with a first recess sized to receive the pressure reduction section and a second portion extending from the first portion, the second portion including a first threaded surface, the unitary body member having a first fluid conduit which is in fluid communication with an exterior of the second portion of the unitary body member at a fluid inlet and with the first recess in the first portion of the unitary body member at a fluid outlet;
a first coupler having a cylindrical body with a second threaded surface on an exterior of the cylindrical body of the coupler and a third threaded surface provided in a second recess of the coupler, the third threaded surface cooperating with the first threaded surface of the second portion of the unitary body member to couple the first coupler to the unitary body member, the first coupler having a second fluid conduit which is in fluid communication with the first fluid conduit of the second portion of the unitary body member when the first coupler is coupled to the unitary body member, wherein the first source of pressurized fluid is coupled to the first coupler through the second threaded surface on the exterior of the cylindrical body of the first coupler; and
a second coupler coupled to the first portion of the unitary body member at a location spaced apart from the first coupler, the second coupler being in fluid communication with a third fluid conduit of the unitary body member, the third fluid conduit of the unitary body member being in fluid communication with the first fluid conduit of the unitary body member at a first location which is prior to fluid outlet of the first fluid conduit, wherein the second source of pressurized fluid is coupled to the second coupler.

Abstract
Fluid regulators provide a fluid to a cannula for use by a person. Fluid conservers also a fluid to a cannula for use by a person. A fluid conserver may be operational in a continuous flow mode of operation and an intermittent flow mode of operation. The selection of either the continuous flow mode of operation and the intermittent flow mode of operation may be based on a position of a flow selector. A home fill device may operate with a fluid conserver and may include an oxygen concentrator which provides a source of fluid.
