GAS DELIVERY CONNECTION ASSEMBLY
BACKGROUND OF THE IN VENTION
This invention relates to improvements in patient gas delivery apparatus of the kind used in the analysis and treattrlent of rcsgiratory disorders. The invention will be described with particular reference to patient gas delivery apparatus used in the treatment of respiratory disorders such as Obstructive Sleep Apnea (OSA) but it is not intended to be limited thereto.
Patient gas delivery apparatus of the kind having a mask worn by a patient and a gas delivery conduit attached to the mask, is commonly used in the analysis and treatment of respiratory disorders. The gas conduit delivers a gas under pressure to the patient.
It is necessary that the gas conduii is detachable from the mask to facilitate cleaning.
Patient gas delivery apparatus typically includes at a minimum, a gas delivery conduit and a nose or full fact mask. In some cases it is a clinical requirement that additional components be included, such as means for C02 washout, for example, vents, anti-asphyxia valves and the like. In some cases, these additional components must be assembled in between the gas delivery conduit and the mask. Problems with prior art assemblies include:
(a) They may be inadvertently assembled without the additional components ' (b) They may be incorrectly assembled, for example, incorrectly aligned (c) During the course of treatment, the patient may inadvertently remove or dismantle the assembly and incorrectly reassemble it.
SITMMA.RY OF THE INVENTION
The present invention is directed towards solving or ameliorating one or more of these problems. The invention will be described with reference to a full face mask and an
2 anti-asphyxia valve, though other forms of mask and additional components may be used.
In one form, the invention resides in a patient gas delivery apparatus including a mask S adapted for communication with a patient's airways, a gas flow generator and gas delivery conduit means, further including an assembly connected in series between the conduit means and the mask, said assembly being formed in at Ieast two parts connected by interengaging connecting means, said assembly further including means for connection to the mask, whereia connection of the assembly to the mask prevents disengagement of the interengaging connecting means such that said at least two pats of the assembly cannot separate whilst the assembly is connected to the mask.
In a further form of the invention, there is provided an assembly for connection in series between a gas delivery conduit means and a patient mask in a patient gas delivery apparatus, the assembly being formed in at least two parts connected by .
interengaging connecting means, said assembly further including means for connection to the mask, wherein connection of the assembly to the mask prevents disengagement of the interengaging connecting means such that said at least two parts of the assembly cannot separate whilst the assembly is connected to the mask.
ZO
Preferably, the means for connection to the mask includes locking means located on the inner side of the mask, that is in the region of the mask that lies adjacent the patient's face, such that the assembly cannot be disconnected from the mask until the mask has been substantially removed from the patient.
Preferably also, the interengaging means connecting the two parts of the assembly includes defeat mesas on a first of the parts which releasably engage a second of the parts, the defeats being held in an engaged position by the mask whilst the assembly is connected to the mask.
Desirably, the mask and conduit are not adapted for direct interconnection without the assembly.

In one preferred form of the invention, the assembly may form a housing for one or more internal components, for example a valve member or a flow sensor.
Further preferred embodiments of the invention will now be described by way of example only with reference to the accompanying drawings in which:
Figure I is a perspective view showing the mask, anti-asphyxia valve housing and conduit connection assembly;
Figure 2 is an exploded view of the anti-asphyxia valve and conduit connection assembly; and Figure 3 is an exploded view of the mask assembly.
In Figure 1 a mask frame is shown generally at 10. The mask is designed to be worn on a patient's face and is secured by means of straps (not shown) received by attachment points 18.
A conduit end assembly is shown generally at 20, including an elbow part 26 having at one end thereof a combined vent/connector piece 28. The elbow and vent/connector piece together form a housing for an anti-asphyxia valve or other internal components (not shown). At the other end of the elbow is a detachable swivel tube 29 for connection of the gas delivery conduit 71 connected to a gas flow generator 70 structured to supply pressurized gas (see Figure 1).
The mask 10 includes a circular aperture 12 sized to receive a mating portion 22 of the vent/connector piece 28. The mating portion 22 has an annular groove 23 formed therein that receives a locking means 30 in the form of a C-shaped clip attached after mating to the mask. The clip 30 has an outside diameter greater than the width of the aperture 12 and an inner diameter adapted to ensure a snug fit within the annular groove 23. The clip 30 is resilient and can expand sufficiently to allow the clip to be fitted into and removed from the groove 23. As shown in Figure. I, the clip 30 is located onto the mating portion 22 on the inside of the mask 10. In this position, the clip 30 is inaccessible while the mask is being worn by a patient. Once the mating portion 22 of the vent/connector piece 28 has been inserted through the aperture 12 and the locking clip placed in the annular groove, the conduit end assembly 20 and the mask 10 cannot be separated without first removing the mask from the patient.
An exploded view of the anti-asphyxia valve and conduit connector assembly is shown in Figure 2.
The end of the elbow 26 adjacent the mask 10 is fitted with an anti-asphyxia valve arrangement that provides an air passage to the patient in the event of failure of the gas flow generator 70, including a valve membrane 27 fitted into the end of elbow 26 and vents 31 in the vent/connector piece 28. During proper operation of the gas flow generator 70, the valve membrane remains in the orientation shown in FIG. 2, closing off the vents 31. In the event of a drop in pressure below a predetermined level, the valve membrane 27 flips to a reverse orientation, opening the vents 31.
Resilient detents 42 on the elbow 26 pass through and engage behind slot-forming formations 44 in the vent/connector piece 28 to provide releasable engagement of the two parts.
The vent/connector piece has a collar 47 that abuts a corresponding surface of the mask 10 to limit the distance that the vent/connector piece can be inserted into the mask aperture 12 (Figure 1). The corresponding surface is an annulus 50 having a protruding rim 51 the outer circumference of which preferably engages the inner surface of the detents 42 on insertion of the mating portion 22 into the aperture 12.
This engagement prevents the detents from being pushed radially inwards suffciently for the detents to disengage from behind the slot-forming formations 44, thus preventing the elbow 26 and vent/connector piece 28 from separating whilst still attached to the mask frame 11, for example during patient treatment. The result of this is that the anti-asphyxia valve arrangement cannot be disassembled without first removing the elbow and vent/connector piece assembly from the mask. However, once disconnected from the mask, the assembly may be readily separated for cleaning and then reassembled.
The other, distal end of elbow 26 has an enlarged diameter portion which receives the 5 swivel tube 29, onto which a flexible gas conduit 71 may be fitted. The swivel tube 29 has a pair of flanges 56 and 57 defining an annular groove 58 therebetween.
The end of swivel tube 29 is inserted into the elbow 26 until the end flange 57 abuts an inner surface (not shown) within elbow 26. In this position the annular groove 58 is at least partially aligned with an annular groove 61 in the exterior of the elbow, which receives a swivel clip 41.
The swivel clip 41 has an inner diameter only slightly greater than the diameter of the groove 61, to ensure a snug fit within the groove. The clip 41 is resilient to permit sufficient expansion for attachment and removal of the clip from the groove.
The groove 61 has slots 59 which receive lugs 62 on the clip. These lugs rotatably engage in the groove 58 between flanges 56 and 57 of the swivel tube. The swivel tube arrangement thus acts as a rotatable coupling between the conduit and the elbow whilst allowing quick attachment and removal of the gas conduit from the elbow regardless of whether the assembly is attached to the mask at the time.
As shown in Figure 3, the mask includes a mask frame 1 l, cushion 13 and cushion clip 14. The cushion is received on a rib 15 extending around the periphery of the mask frame 11. The cushion is held to the rib by the cushion clip 14. The mask frame includes attachment points 18 that receive straps (not shown) for attaching the mask to the patient, an aperture 16 for receiving an air vent 17, and measurement ports 19.
While particular embodiments of this invention have been described, it will be evident to those skilled in the art that the present invention may be embodied in other specific forms without departing from the essential characteristics thereof. The present embodiments and examples are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than the foregoing description, and all changes which come within the meaning and range of equivalency of the claims arc therefore intended to be embraced therein.
