DETAILED DESCRIPTION OF ILLUSTRATED EMBODIMENTS
[0030] FIGS. 1-3 illustrate a storage system 10 constructed
according to an embodiment of the present invention. The storage
system 10 is structured for use with an apparatus 12 that delivers
a supply of pressurized breathable air to a patient for treatment,
e.g., of Sleep Disordered Breathing (SDB) with CPAP or Non-Invasive
Positive Pressure Ventilation (NIPPV). The apparatus 12 generally
includes a flow generator 14, a power cord 16 for the flow
generator 14, an air delivery conduit 18, and a patient interface
20. As discussed in greater detail below, the storage system 10
includes a container 22 adapted to conveniently store the
components of the apparatus 12. Moreover, the container 22 is
structured to enable operation of the flow generator 14 while it is
stored within the container 22.
Flow Generator
[0031] The flow generator 14 is structured to generate a supply of
pressurized air to be provided to a patient for treatment. The flow
generator 14 includes a housing 24 and a blower supported within
the housing 24. As is known in the art, the blower is operable to
draw a supply of air into the housing 24 through one or more intake
openings and provide a pressurized flow of air at an outlet 26.
[0032] The flow generator 14 includes a power inlet (not shown) to
which a power cord 16 may be selectively engaged for supplying
power to the flow generator 14. The power inlet and the power cord
16 may have any suitable structure for supplying power to the flow
generator 14. However, the flow generator 14 may be powered in any
other suitable manner, e.g., by battery.
[0033] The flow generator 14 also includes a control panel 28 that
is operable to receive input and to control operation of the flow
generator 14 based on the input. The control panel 28 may provide a
display screen and one or more control features, e.g., rotatable
knob, buttons. The control features may be manually selected to
adjust the operating parameters of the flow generator 14.
[0034] The housing 24 of the flow generator 14 includes an upper
wall 30, a lower wall 32, and front and rear side walls 34, 36. In
the illustrated embodiment, the control panel 28 and the outlet 26
of the flow generator 14 are both provided on the front side wall
34 of the housing 24, and the power inlet is provided on the rear
side wall 36 of the housing 24. However, the control panel 28,
outlet 26, and power inlet may be provided on any suitable wall of
the housing 24 and in any suitable arrangement, e.g., common walls,
different walls, etc.
Air Delivery Conduit
[0035] The supply of pressurized air is delivered to the patient
via the air delivery conduit 18 that includes one end 38 coupled to
the outlet 26 of the flow generator 14 and an opposite end 40
coupled to the patient interface 20. The air delivery conduit 18
may have any suitable construction, and may be coupled to the flow
generator 14 and the patient interface 20 in any suitable manner as
is known in the art.
Patient Interface
[0036] The patient interface 20 comfortably engages the patient's
face and provides a seal. The patient interface 20 may have any
suitable configuration as is known in the art, e.g., full-face
mask, nasal mask, oro-nasal mask, mouth mask, nasal prongs, etc.
Also, any suitable headgear arrangement 42 may be utilized to
comfortably support the patient interface 20 in a desired position
on the patient's face.
Storage Container
[0037] The container 22 of the storage system 10 is in the form of
a storage case that provides storage compartments 44, 46 adapted to
conveniently store the flow generator 14 and the patient interface
20. Additionally, the storage case 22 provides a cable management
system 50 structured to conveniently handle the power cord 16 and
the air delivery conduit 18, as discussed in greater detail
below.
[0038] The case 22 includes a first portion 52 and a second portion
54 that are structured to support various components. The first and
second portions 52, 54 may include padded or impact resistant walls
or surfaces to protect the components. In the illustrated
embodiment, the first portion 52 provides the storage compartments
44, 46. The second portion 54 is movably mounted to the first
portion 52, e.g., by hinges, for movement between an open position
(as shown in FIGS. 1 and 2) and a closed position (as shown in FIG.
3). In the open position, the second portion 54 uncovers the
storage compartments 44, 46 to allow access to the storage
compartments 44, 46. In the closed position, the second portion 54
closes the storage compartments 44, 46 to inhibit access to the
storage compartment 44, 46. Thus, the flow generator 14 and patient
interface 20 may be inserted into and removed from respective
storage compartments 44, 46 when the case 22 is in the open
position, and the case 22 encloses the flow generator 14 and the
patient interface 20 to prevent removal therefrom when the case 22
is in the closed position. The case 22 also provides handles 56
that allow one to conveniently carry and transport the case 22 when
in the closed position. Additionally, when the case 22 is in the
closed position, the first and second portions 52, 54 provide a
base structured to maintain the case 22 in a substantially upright
position on a support surface as shown in FIG. 3.
[0039] In an embodiment, the case 22 may be provided with a mobile
mount, e.g., case 22 attaches to a wheel chair to allow patient
mobility and equipment protection. Also, the mobile mount may
assist to contain noise emissions.
[0040] As illustrated, the storage compartments 44, 46 are provided
in the first portion 52 of the case 22. The shape and size of each
storage compartment 44, 46 generally corresponds with the shape and
size of the component to be received therein. For example, the
compartment 44 is suitably sized and shaped to receive the flow
generator 14, and the compartment 46 is suitably sized and shaped
to receive the patient interface 20 including headgear 42. Each
compartment 44, 46 may be formed from a cushioning material that
absorbs impact and stably supports the respective component within
the compartment.
[0041] The first portion 52 also provides an elongated opening 58
that allows access to the compartment 44 and the flow generator 14
supported therein. Specifically, the side wall of the first portion
52 includes an opening 58 that exposes the front side wall 34 of
the flow generator 14 when it is supported within the compartment
44. This allows access to the control panel 28 and the outlet 26 so
that the user can operate and/or adjust the flow generator 14 when
the case 22 is in its closed position. The opening 58 also allows
for the venting/cooling of the flow generator, and for the
introduction of fresh air to be pressurized by the blower of the
flow generator. The bottom wall of the compartment 44 may include
one or more additional openings, or be made at least partially of a
porous material, to allow cooling, venting, and/or entry of fresh
air to the blower inlet.
Cable Management System
[0042] As noted above, the storage case 22 provides a cable
management system 50 to conveniently handle the air delivery
conduit 18 and the power cord 16. The cable management system 50
allows the user to connect the air delivery conduit 18 and the
power cord 16 to the flow generator 14 when the case 22 is in its
open position, and then dispense and retract the connected air
delivery conduit 18 and power cord 16 from the case 22 when the
case 22 is in its closed position. This arrangement, along with the
opening 58 in the first portion 52 that allows access to the
control panel 28 of the flow generator 14, enables convenient
operation of the apparatus 12 when the case 22 is in its closed
position. Therefore, it is not necessary to remove the flow
generator or its power cord and/or the air delivery tube from the
case during operation of the flow generator in a therapy
session.
[0043] In the illustrated embodiment, the cable management system
50 includes a first reel 60 structured to dispense and retract the
air delivery conduit 18, and a second reel 62 structured to
dispense and retract the power cord 16. The first and second reels
60, 62 are rotatably mounted to the second portion 54. In the
illustrated embodiment, each reel 60, 62 includes a handle 64 to
manually rotate the respective reel 60, 62 and thereby control the
dispersal and retraction of the air delivery conduit 18 and the
power cord 16. However, the reels 60, 62 may be rotated in any
other suitable manner, e.g., spring, motor. For example, the reels
60, 62 may be spring loaded to retract and may be locked in any
extended position.
[0044] When the flow generator 14 is mounted within the compartment
44, the front side wall 34 is adjacent the reel 60 to enable one
end 38 of the air delivery conduit 18 to be coupled to the outlet
26 and the opposite end 40 to extend through an opening 66 provided
in the second portion 54. Sufficient space is provided to enable
the air delivery conduit 18 to connect to the outlet 26 while the
flow generator 14 is within the respective storage compartment 44.
Also, structure may be provided to align and maintain the air
delivery conduit 18 in a position adjacent the opening 66. Further,
a movable door 68 may be provided to selectively close the opening
66.
[0045] In an embodiment, the air delivery conduit 18 may be
collapsible to a substantially flat condition in order to
facilitate storage in a compact manner. In use, the air delivery
conduit 18 would expand to allow the passage of air therethrough.
For example, FIGS. 3B and 3C illustrate an air delivery conduit 18
including a spring 506 within the air passage. As illustrated, the
spring 506 includes a Z-shaped cross-sectional configuration. The
spring 506 is biased to maintain the air passage open in use (FIG.
3B), and the spring 506 is collapsible to allow the conduit to
assume a substantially flat condition (FIG. 3C).
[0046] When the flow generator 14 is mounted within the compartment
44, the front side wall 36 is adjacent the reel 62 to enable one
end 15 of the power cord 16 to be coupled to the power inlet and
the opposite end 17 to extend through an opening 70 provided in the
second portion 54. A recess 72 is provided to enable the power cord
16 to connect to the power inlet while the flow generator 14 is
within the respective storage compartment 44. Also, structure may
be provided to align and maintain the power cord 16 in a position
adjacent the opening 70. Further, a movable door 74 may be provided
to selectively close the opening 70.
[0047] Also, a cover may be provided to enclose the reels 60, 62
within the second portion 54 of the case 22. The cover may include
openings to allow access to the reel handles 64 and to allow access
to respective ends of the air delivery conduit 18 and the power
cord 16.
[0048] When the flow generator 14 is mounted within its respective
compartment 44 of the case 22, respective ends of the air delivery
conduit 18 and the power cord 16 may be coupled to the flow
generator 14 as shown in FIG. 2. Alternatively, the air delivery
conduit 18 and the power cord 16 may be coupled to the flow
generator 14 just prior to use.
[0049] When it is desired to operate the apparatus 14, the case 22
is moved into its open position to remove the patient interface 20
from its respective compartment 46, and then the case 22 is moved
back into its closed position. The air delivery conduit 18 and the
power cord 16 are dispensed from the respective openings 66, 70 in
the case 22 by pulling on respective ends until desired lengths are
achieved. Alternatively, the air delivery conduit 18 and the power
cord 16 may be dispensed by rotating respective handles 64 when the
case 22 is in its open position. Once dispensed, the end 40 of the
air delivery conduit 18 is coupled to the patient interface 20, and
the end 17 of the power cord 16 is coupled to a power outlet, as
shown in FIG. 3. The flow generator 14 can then be operated while
inside the case 22 via the control panel 28 that is accessible
through the opening 58 in the case 22.
[0050] When the treatment session is complete, the air delivery
conduit 18 is disconnected from the patient interface 20, and the
power cord 16 is disconnected from the power outlet. The case 22 is
moved to its open position, and the air delivery conduit 18 and the
power cord 16 can be reeled into the case 22 by respective handles
64. Also, the patient interface 20 can be placed into its
respective compartment 46 within the case 22. Then, the case 22 may
be moved into its closed position that allows convenient transport
and storage of the apparatus 12.
[0051] In illustrated embodiment, the opening 58 allows access to
the control panel 28 when the case 22 is in the closed position. It
should be understood that the shape, size, and/or placement of the
opening 58 may vary depending on the configuration of the flow
generator 14. That is, any suitable opening 58 may be provided in
any suitable side wall of the case 22 to allow access to the
control panel 28. Also, the opening 58 may be covered by a
flexible, clear membrane, e.g., polyester film, to allow the
control panel 28 to be adjusted while maintaining a closed
compartment, e.g., to prevent dust ingress.
[0052] Also, it is noted that the cable management system 50 is
optional and additional compartments may be provided within the
case 22 to store the air delivery conduit 18 and the power cord 16.
Moreover, additional openings may be provided through the case 22
to allow access to the power inlet and the outlet 26 of the flow
generator 14 when the case 22 is in the closed position. The
openings may take various forms, and may be configured to
correspond with the shape and/or size of the power inlet and/or
outlet 16. The openings would allow the air delivery conduit 18 and
the power cord 16 to connect to the flow generator 14 while it is
within the case 22, thereby allowing the apparatus 12 to operate
while the flow generator 14 is within the case 22.
[0053] Further, the first portion 52 and/or the second portion 54
may be constructed at least in part of a sound proofing material
adapted to muffle sound generated from the flow generator 14 while
in use.
Storage Nest
[0054] As shown in FIG. 4, the container may be in the form of a
nest 80 that provides storage compartments 82, 84 adapted to
conveniently store the flow generator 14, the patient interface 20,
and the air delivery conduit 18. Specifically, the nest includes a
bottom wall and side walls extending from the bottom wall that
define storage compartments 82, 84 having upwardly facing openings
adapted to receive the flow generator 14, the patient interface 20,
and the air delivery conduit 18. The shape and size of each storage
compartment 82, 84 generally corresponds with the shape and size of
the component to be received therein. For example, the compartment
82 is suitably sized and shaped to receive the flow generator 14,
and the compartment 84 is suitably sized and shaped to receive the
patient interface 20 and air delivery conduit 18. Each compartment
82, 84 may be formed from a cushioning material, e.g., foam
material, that absorbs impact and stably supports the respective
component within the compartment. The material that surrounds the
flow generator may be configured (e.g., mesh-like or porous) to
allow fresh gas to enter the blower. Also, the material may provide
further utility, e.g., sound proofing.
[0055] At least one of the side walls of the nest 80 provides an
opening 86 that allows the air delivery conduit 18 to pass
therethrough when connected to the flow generator 14. Specifically,
the nest 80 includes an opening 86 that aligns with the outlet 26
of the flow generator 14 so that the user can access the outlet 26
and connect the air delivery conduit 18 thereto when the flow
generator 14 is within the nest 80. The opening 86 may also be
utilized to allow a power cord to connect to the power inlet of the
flow generator 14. Alternatively, an additional opening may be
provided through the nest 80 to allow access to the power inlet.
Moreover, an opening may be provided to allow access to the control
panel of the flow generator 14.
[0056] The nest 80 may be suitably sized to allow it to be
removably mounted into a container for storage and/or
transportation purposes. For example, FIG. 5 illustrates the nest
80 mounted within a briefcase 90. As illustrated, the briefcase 90
includes a first portion 92 movably mounted to a second portion 94,
e.g., by hinges, for movement between an open position and a closed
position. In the open position shown in FIG. 5, the nest 80 may be
mounted into and removed from the storage space provided by the
first portion 92. In the closed position, the briefcase 90 encloses
the nest 80 to prevent removal therefrom. The briefcase 90 also
provides a handle 96 that allows one to conveniently handle and
transport the briefcase 90 when in the closed position.
Additionally, the second portion 94 may provide sound proofing
material adapted to muffle sound generated from the flow generator
14 while in use.
[0057] The first portion 92 of the briefcase 90 also provides an
opening 98 that aligns with the opening 86 provided on the nest 80.
This arrangement allows access to the outlet 26 so that the user
can operate the flow generator 14 when the briefcase 90 is in the
closed position. That is, the air delivery conduit 18 (in dashed
lines) can extend from the outlet of the flow generator 14 and
through the aligned openings 86, 98.
[0058] In an alternative embodiment, the nest 80 may be mounted
into a case similar to that shown in FIGS. 1-3. Specifically, the
case 22 may be modified to include a storage space in the first
portion 52 adapted to receive the nest 80.
[0059] As shown in FIG. 6, the nest 80 may be mounted within the
drawer 100 of a cabinet 102, e.g., bedside cabinet. As illustrated,
the drawer 100 is slidably mounted to the cabinet 102 for movement
between an open position and a closed position. In the open
position shown in FIG. 6, the nest 80 may be mounted into and
removed from the storage space provided by the drawer 100. In the
closed position, the cabinet 102 encloses the nest 80 to prevent
removal therefrom. The drawer 100 and/or cabinet 102 may provide
sound proofing material adapted to muffle sound generated from the
flow generator 14 while in use. In an embodiment, the nest 80 may
include top and bottom portions 85, 87 that fully enclose the flow
generator 14 with a cushioning material, e.g., foam, to provide
optimal sound proofing as shown in FIG. 6B.
[0060] The drawer 100 also provides an opening that aligns with the
opening 86 provided on the nest 80. This arrangement allows access
to the outlet 26 so that the user can operate the flow generator 14
when the drawer 100 is in the closed position. That is, the air
delivery conduit 18 (in dashed lines) can extend from the outlet of
the flow generator 14 and through the aligned openings.
[0061] It is noted that the nest 80 may be mounted in any other
suitable storage space. Moreover, the nest 80 may be suitably
modified to include storage compartments of various shapes and
sizes, and one or more openings to allow access to the
compartments.
Slim Flow Generator Design
[0062] The flow generator itself may be structured to facilitate
transport and convenient storage. For example, FIGS. 7-10
illustrate a flow generator 214 having a relatively slim streamline
design (similar to the flow generator 14 illustrated above).
Specifically, the flow generator 214 is structured such that the
housing walls have substantially flat configurations that provide
substantially flat exterior surfaces. Moreover, the flow generator
214 is structured such that the length and width are substantially
longer than the height. Thus, the height is relatively short,
thereby providing a thin configuration. This configuration allows
the flow generator 214 to be placed in tight locations, thereby
concealing its location while still making it convenient for
use.
[0063] In an embodiment, the motor of the flow generator 214 may
have a substantially flat configuration to enable the "slim" flow
generator design. An example of such a flat motor is disclosed in
"Engineering Penn State", The Magazine of the Penn State College of
Engineering, Summer 2003, Vol. 19, No. 3. As shown in FIG. 7B, the
blower 203 may be axially aligned with the flat motor 201.
Alternatively, as shown in FIG. 7C, the blower 203 may be offset
from the flat motor 201, e.g., side by side. Ideally, the
motor/blower configuration is thin enough to prevent mattress bulge
(e.g., see FIG. 9).
[0064] As shown in FIG. 7, the flow generator 214 may be supported
on a bedside table 202 in a horizontal orientation. As noted above,
the upper wall of the housing is substantially flat, which allows
it to support one or more objects (e.g., glass, book, lamp, etc.)
thereon in a stable manner. As shown in FIG. 8, the slim flow
generator design allows the flow generator 214 to positioned in a
vertical orientation in the limited space between a bed 204 and a
bedside table 202. Also, the slim design allows the flow generator
214 to positioned in a horizontal orientation under the mattress of
a bed 204 as shown in FIG. 9.
[0065] In another embodiment, the flow generator 214 may include
structure, e.g., brackets, that allows it to be mounted. For
example, as shown in FIG. 10, the flow generator 214 may be mounted
behind a bed 204, e.g., to headboard of the bed or to the wall
adjacent the bed. In an embodiment, the bracket may be attached to
the bed 204 and the flow generator 214 may be removably attached to
the bracket, e.g., clips on/off the bracket. As shown in FIG. 10B,
a bracket 207 may be attached to the flow generator 214, e.g.,
removably attached, that is adapted to engage the headboard 205 of
the bed 204.
[0066] It is noted that the control panel, outlet, and power inlet
of the flow generator 214 may be provided on any suitable wall of
the housing. Moreover, the location of these features may be
determined at least in part on the desired storage location of the
flow generator.
Flow Generator Stand
[0067] As shown in FIGS. 11-13, a stand 310 may be provided along
with a flow generator 314 to support the flow generator 314 in a
generally vertical orientation. Thus, the stand 310 constitutes a
storage system adapted to conveniently store the flow generator
314. In the illustrated example, the flow generator 314 has a
relatively slim design (e.g., similar to the flow generators 14,
214), and the stand 310 includes spaced apart arms 311 that engage
opposing walls of the flow generator 314 to stably support the flow
generator 314 in the vertical orientation. This arrangement allows
the flow generator 314 to be conveniently and stably positioned in
any suitable location. One or both of the arms can be adjustable
(e.g., via a sliding track arrangement or a pin and groove
arrangement or other conventional adjustment assemblies) to allow
the support of flow generators having various widths. For example,
the stand 310 may accommodate flow generators having a width of
between 2-20 cm.
[0068] In another embodiment, a stand 410 may be structured to
support the flow generator 414 across its length rather than its
width, as shown in FIGS. 14 and 15. Similar to the above, one or
both of the arms of the stand 410 may be adjustable to allow the
support of flow generators having various lengths. The stand and
flow generator may include cooperating structure, e.g., a tongue
and groove arrangement, to prevent the flow generator from rotating
relative to the stand, thereby holding the flow generator
upright.
[0069] While the invention has been described in connection with
what are presently considered to be the most practical and
preferred embodiments, it is to be understood that the invention is
not to be limited to the disclosed embodiments, but on the
contrary, is intended to cover various modifications and equivalent
arrangements included within the spirit and scope of the invention.
In addition, while the invention has particular application to
patients who suffer from OSA, it is to be appreciated that patients
who suffer from other illnesses (e.g., congestive heart failure,
diabetes, morbid obesity, stroke, barriatric surgery, etc.) can
derive benefit from the above teachings. Moreover, the above
teachings have applicability to storage of components in general
for use with patients and non-patients alike.
