## Abstract

A hose formed by a plurality of subunits in tandem arrangement particularly useful for use in a breathing apparatus. Each of the subunits comprises a plurality of repeat subunits in tandem arrangement, each of said subunits comprising: a proximal subunit-to-subunit connector member at a proximal end of each subunit; a distal subunit-to-subunit connector member at a distal end of each subunit; at least one interlocking ring; and at least one gas and/or moisture-permeable member disposed intermediate and connected to the at least one interlocking ring and one or both of the proximal and distal subunit-to-subunit connector members. In other embodiments, the member intermediate the interlocking ring and subunit-to-subunit connector members is a non-rigid member, and more particularly has a frusto-conical shape.

## Claims

### Claim 1

A hose for delivering breathing gas, the hose comprising:
at least one non-rigid member providing the hose with multiple degrees of freedom of movement while delivering breathing gas, each said non-rigid member having a frusto-conical shape; and
at least two rigid or semi-rigid member preventing loss of cross-sectional area and at least providing a swivel movement between two of said rigid or semi-rigid members.

### Claim 2 (depends on 1)

A hose according to claim 1, wherein said at least one non-rigid member is a flexible fabric-like member.

### Claim 3 (depends on 2)

A hose according to claim 2, wherein said at least one non-rigid member is a permeable material.

### Claim 4 (depends on 1)

A hose according to claim 1, comprising a plurality of non-rigid members and a plurality of rigid or semi-rigid members, wherein said non-rigid members and said rigid or semi-rigid members are alternately arranged along said hose.

### Claim 5 (depends on 1)

A hose according to claim 1, wherein said rigid or semi-rigid members are connector rings connecting adjacent non-rigid members together.

### Claim 6 (depends on 1)

A hose according to claim 1, wherein said non-rigid members include an axial flange sized to snugly fit on an adjacent rigid or semi-rigid member.

### Claim 7 (depends on 1)

A hose according to claim 1, wherein said hose is gas or liquid permeable.
