Abstract

A tubing assembly for use with a patient interface device includes a manifold portion structured to be coupled to a conduit carrying a flow of breathing gas and a number of tubular portions. Each tubular portion extends from the manifold portion to a distal end which is structured to be coupled to the patient interface device. Each tubular portion is structured to communicate the flow of breathing gas from the manifold portion to the patient interface device. Each tubular portion comprises an adjustment element which provides for a characteristic of the tubular portion to be selectively varied.

First claim

What is claimed is:

1. A tubing assembly for use with a patient interface device in delivering a flow of breathing gas to the airway of a user, the tubing assembly comprising:
a manifold portion structured to be disposed generally at the top of the user's head and adapted to be coupled to a conduit carrying the flow of breathing gas; and
a number of tubular portions, each tubular portion extending from the manifold portion to a distal end which is structured to be coupled to the patient interface device, each tubular portion being structured to communicate the flow of breathing gas from the manifold portion to the patient interface device,
wherein each tubular portion comprises an adjustment element which provides for a length of the tubular portion to be selectively varied,
wherein the adjustment element comprises a number of tubular adjustment members, each comprising:
a body having a predetermined length and defining a hollow passage therethrough;
a protruding portion extending from a first end of the body, which is of similar form as one of the distal end of the tubular portion or an end portion of the patient interface device; and
a receptacle portion extending from an opposite second end of the body which is of similar form as the other one of the distal end of the tubular portion or the end portion of the patient interface device, wherein each protruding portion is structured to be readily snap fit into the receptacle portion of another tubular adjustment member or the other one of the distal end of the tubular portion or the end portion of the patient interface device, and

wherein the body is a unitary member and the protruding portion and the receptacle portion are portions of the unitary member.

2. A respiratory interface system for use in delivering a flow of breathing gas to an airway of a user, the system comprising:
a patient interface device structured to sealingly engage the airway of the user; and
a tubing assembly comprising:
a manifold portion structured to be disposed generally at the top of the user's head and adapted to be coupled to a conduit carrying the flow of breathing gas; and
a number of tubular portions, each tubular portion extending from the manifold portion to a distal end which is structured to be coupled to the patient interface device, each tubular portion being structured to communicate the flow of breathing gas from the manifold portion to the patient interface device,
wherein each tubular portion comprises an adjustment element which provides for a length of the tubular portion to be selectively varied,
wherein the adjustment element comprises a number of tubular adjustment members, each comprising:
a body having a predetermined length and defining a hollow passage therethrough:
a protruding portion extending from a first end of the body, which is of similar form as one of the distal end of the tubular portion or an end portion of the patient interface device; and
a receptacle portion extending from an opposite second end of the body which is of similar form as the other one or the distal end of the tubular portion or the end portion of the patient interlace device wherein each protruding portion is structured to be readily soap fit into the receptacle portion of another tubular adjustment member or the other one of the distal end of the tubular portion or the end portion of the pattern interface device, and

wherein the body is a unitary member and the protruding portion and the receptacle portion are portions of the unitary member.
