Abstract

An improved connection apparatus is structured to extend between a mask ( 8 ) and a headgear ( 12 ). The headgear has a first strap ( 16 ) and a second strap ( 20 ) structured to overlie the patient's head. The connection apparatus can be generally stated as including a clip apparatus ( 24 ) and a face plate. The clip apparatus can be generally stated as including a clip ( 32 A,B) having a first mount ( 44 ) that is structured to be connected with the first strap and a second mount ( 48 ) that is structured to be connected with the second strap. The face plate is structured to overlie at least a portion of the mask. The face plate ( 28 ) can be generally stated as including an attachment apparatus having a connection upon which the clip is structured to be disposed. At least a portion of the clip is removable from at least a portion of the connection.

First claim

1 . A connection apparatus that is structured to extend between a mask and a headgear, the mask being structured to provide a flow of breathing gas to a patient, the headgear having a first strap and a second strap, at least a portion of the first strap being structured to overlie a region of the patient's head, at least a portion of the second strap being structured to overlie at least one other region of the patient's head, the connection apparatus comprising:
a clip apparatus comprising a having a first mount that is structured to be connected with the first strap and a second mount that is structured to be connected with the second strap; and a face plate that is structured to overlie at least a portion of the mask, the face plate comprising an attachment apparatus having a connection upon which the clip is structured to be disposed, the connection comprising a first connection element and a second connection element, one of the first and second connection elements being a pivotable connection element that extends between the face plate and the clip and that is structured to enable the clip to be pivotable with respect to the face plate, at least a portion of the clip being removable from at least a portion of the connection.

2 . (canceled)

3 . The connection apparatus of claim 1 , wherein the pivotable connection element is removable from at least one of the face plate and the clip and is structured to permit the face plate and the clip to be separated.

4 . The connection apparatus of claim 1 , wherein the other of the first and second connection elements is a fixed connection element that is structured to be movable between a first condition extending between the face plate and the clip and a second condition disconnected from at least one of the face plate and the clip, the fixed connection element in the first condition being structured to resist pivoting of the clip with respect to the face plate.

5 . The connection apparatus of claim 1 , wherein at least one of the face plate and the clip has a slot formed therein within which the pivotable connection element is slidably disposed.

6 . The connection apparatus of claim 5 , wherein the other of the first and second connection elements is a fixed connection element that is structured to be movable between a first condition extending between the face plate and the clip and a second condition disconnected from at least one of the face plate and the clip, the fixed connection element in the first condition being structured to resist pivoting of the clip with respect to the face plate; and wherein the slot comprises a seat that is structured to receive the pivotable connection element in the first condition of the fixed connection element.

7 . The connection apparatus of claim 1 , wherein the connection comprises a seat that is structured to removably receive at least a portion of the clip.

8 . The connection apparatus of claim 7 , wherein the first and second mounts are situated at alternate sides of the seat when the clip is received on the seat.

9 . The connection apparatus of claim 8 , wherein the clip comprises a finger grip situated anterior of the seat and the first and second mounts when the clip is received on the seat and the mask is situated on the patient.

10 . The connection apparatus of claim 7 , wherein the face plate comprises a resilient leg, the seat being situated at a free end of the leg, the leg being movable between a free state wherein the at least portion of the clip is removed from the seat and a deflected state wherein the at least portion of the clip is received in the seat, the seat in the free state of the leg being structured to be in a position situated anterior to the position of the seat in the deflected state with the mask situated on the patient.

11 . The connection apparatus of claim 10 , wherein the at least portion of the clip received in the seat is pivotably disposed in the seat.

12 . The connection apparatus of claim 10 , wherein the clip comprises a base that is structured to be received in the seat and a lug that is structured to extend in a direction posterior to the seat when the base that is received in the seat, the first and second mounts being situated on the lug at a location distal to the base.

13 . The connection apparatus of claim 1 , wherein the clip comprises a base that is structured to be disposed on the connection and a lug that is structured to extend in a direction posterior to the connection when the base is disposed on the connection and the mask is situated on the patient, at least one of the first mount and the second mount being situated on the lug at a location distal to the base.

14 . The connection apparatus of claim 13 , wherein the at least one of the first mount and the second mount is the one of the first mount and the second mount with which is connected the one of the first strap and the second strap that is disposed superior to the other of the first strap and the second strap when mask is situated on the patient.

15 . The connection apparatus of claim 13 , wherein the at least one of the first mount and the second mount is the one of the first mount and the second mount with which is connected the one of the first strap and the second strap that is disposed inferior to the other of the first strap and the second strap when mask is situated on the patient, and wherein the clip further comprises a flexible brace situated on the lug at a location distal to the base, the brace engaging the other of the first strap and the second strap and being structured to resist movement of the other of the first strap and the second strap in a direction toward the eye of the patient.

16 . The connection apparatus of claim 15 , wherein the other of the first strap and the second strap is longitudinally slidable with respect to the brace.
