Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] Not applicable.
FIELD OF THE INVENTION
[0002] The present invention generally relates to a snorkel with
small respiratory dead space and method thereof. Although the
invention will be illustrated, explained and exemplified by using
diaphragm check valves, it should be appreciated that the present
invention can also be applied with other designs.
BACKGROUND OF THE INVENTION
[0003] As a popular recreational activity, particularly at tropical
resort locations, snorkeling allows observation of marine life
while swimming on the surface of the water. A snorkeler must
therefore be able to hold the head under water while breathing, and
he/she is typically equipped with a diving mask for viewing, fins,
and a shaped tube called a snorkel for breathing. In cooler waters,
a wetsuit may also be worn. The snorkel is a draw-type snorkel for
use under water that includes means extending to the surface of the
water to allow the user to draw air from the atmosphere with no
means to supply respiratory gas under positive pressure as in scuba
diving. A snorkel includes a tube and a mouthpiece which fits into
the snorkeler's mouth. The mouthpiece is intended to be disposed
below the water level, and the tube's inlet is intended to be
disposed above the water level.
[0004] Ordinary snorkel has only one tube for inhalation and
exhalation. When a snorkeler wears an ordinary snorkel, he/she
always breathes in portion of exhaled CO.sub.2 contaminated air and
not the fresh air. Snorkelers wearing the ordinary snorkel will
acuminate a large amount of CO.sub.2 in the blood after a long
period of snorkeling in one section to lead to hypercapnia.
[0005] Hypercapnia can cause headache, lethargy, drowsiness,
confusion and, if sever, can lead to coma and death. Hypercapnia
may be the cause of death of several snorkelers in Hawaii every
year.
[0006] Therefore, there exists a need to overcome the
aforementioned problems. Advantageously, the present invention
provides a snorkel with small respiratory dead space and method
thereof that allows the snorkeler always breaths in fresh air and
prevents the acumination of CO.sub.2 in the blood to cause
hypercapnia.
SUMMARY OF THE INVENTION
[0007] One aspect of the present invention provides a snorkel 100
comprising (1) a mouthpiece or mask for a snorkeler to breathe air
in and out; (2) a tube comprising an inhalation lumen and an
exhalation lumen; (3) a distal one-way inhalation valve placed
inside the inhalation lumen; and (4) a distal one-way exhalation
valve placed inside the exhalation lumen. The tube has a distal end
that is open to ambient air when the snorkeler is snorkeling and a
proximal end that is connected to the mouthpiece or mask for air to
inhale into the mouthpiece or mask from the inhalation lumen and to
exhale from the mouthpiece or mask to the exhalation lumen 140.
[0008] Another aspect of the invention provides a method for
reducing a volume of a respiratory dead space in a snorkel,
comprising:
[0009] providing a mouthpiece or mask for a snorkeler to breathe
air in and out;
[0010] providing a tube comprising an inhalation lumen and an
exhalation lumen, wherein the tube has a distal end that is open to
ambient air when the snorkeler is snorkeling and a proximal end
that is connected to the mouthpiece or mask for air to inhale into
the mouthpiece or mask from the inhalation lumen and to exhale from
the mouthpiece or mask to the exhalation lumen;
[0011] placing a distal one-way inhalation valve inside the
inhalation lumen;
[0012] placing a distal one-way exhalation valve inside the
exhalation lumen; and
[0013] placing a proximal one-way inhalation valve inside the
inhalation lumen and between the distal one-way inhalation valve
and the mouthpiece or mask, and/or a proximal one-way exhalation
valve inside the exhalation lumen and between the distal one-way
exhalation valve and the mouthpiece or mask.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0027] In the following description, for the purposes of
explanation, numerous specific details are set forth in order to
provide a thorough understanding, of the present invention. It is
apparent, however, to one skilled in the art that the present
invention may be practiced without these specific details or with
an equivalent arrangement.
[0028] Where a numerical range is disclosed herein, unless
otherwise specified, such range is continuous, inclusive of both
the minimum and maximum values of the range as well as every value
between such minimum and maximum values. Still further, where a
range refers to integers, only the integers from the minimum value
to and including the maximum value of such range are included. In
addition, where multiple ranges are provided to describe a feature
or characteristic, such ranges can be combined.
[0029] It is also to be understood that the terminology used herein
is for the purpose of describing particular embodiments only, and
is not intended to limit the scope of the invention. For example,
when an element is referred to as being "on", "connected to", or
"coupled to" another element, it can be directly on, connected or
coupled to the other element or intervening elements may be
present. In contrast, when an element is referred to as being
"directly on", "directly connected to", or "directly coupled to"
another element, there are no intervening elements present.
[0030] With reference to FIG. 1, a snorkel 100 includes a
mouthpiece or mask 110 for a snorkeler to breathe air in and out.
The mouthpiece may be made of natural rubber or silicone rubber. A
tube 120 includes an inhalation lumen 130 and an exhalation lumen
140. The tube 120 has a distal end that is open to ambient air when
the snorkeler is snorkeling and a proximal end that is connected to
the mouthpiece or mask 110 for air to inhale into the mouthpiece or
mask 110 from the inhalation lumen 130 and to exhale from the
mouthpiece or mask 110 to the exhalation lumen 140. As such, the
snorkel 100 may be used for breathing air from above the surface of
water when the wearer's head is facing downwards in the water with
the mouth and the nose submerged. In snorkel 100, a distal one-way
inhalation valve 150 is placed inside the inhalation lumen 130; and
a distal one-way exhalation valve 160 placed inside the exhalation
lumen 140.
[0031] Snorkels will, more or less, constitute respiratory dead
space or volume. When the user takes in a fresh breath, some of the
previously exhaled air which remains in the snorkel is inhaled
again, reducing the amount of fresh air in the inhaled volume, and
increasing the risk of a buildup of carbon dioxide in the blood,
which can result in hypercapnia. Because of valves 150/160, the
respiratory dead space or volume is reduced. With reference to FIG.
2, the snorkel 100 may further comprise a proximal one-way
inhalation valve 170. It may be placed inside the inhalation lumen
130 between the distal one-way inhalation valve 150 and the
mouthpiece or mask 110, for further reducing the volume of
respiratory dead space. With reference to FIG. 3, the snorkel 100
may further comprise a proximal one-way exhalation valve 180. It
may be placed inside the exhalation lumen 140 between the distal
one-way exhalation valve 160 and the mouthpiece or mask 110, for
further reducing the volume of respiratory dead space.
[0032] With reference to FIG. 4, the snorkel 100 may further
comprise both the proximal one-way inhalation valve 170 and the
proximal one-way exhalation valve 180. This design can minimize the
volume of respiratory dead space or volume.
[0033] With reference to FIG. 5, the snorkel 100 may further
include one or more anti-collapse one-way inhalation valves 190. It
or they may be placed inside the inhalation lumen 130 between the
distal one-way inhalation valve 150 and the proximal one-way
inhalation valve 170. Alternatively or in addition, the snorkel 100
may further comprise one or more anti-collapse one-way exhalation
valves 200. It or they may be placed inside the exhalation lumen
140 between the distal one-way exhalation valve 160 and the
proximal one-way exhalation valve 180. With anti-collapse one-way
inhalation valves 190/200, the snorkel of the invention for users
with larger lung capacities can exceed 38 centimeters in length and
230 cubic centimeters in internal volume. For users with smaller
lung capacities, the snorkel of the invention can exceed 35
centimeters in length and 150 cubic centimeters in internal volume.
In some embodiments, the snorkels of the invention can have a total
length greater than 48 cm and to have an inner lumen diameter
greater than 2.3 cm.
[0034] In a preferred embodiment, each of the above one-way valves
(e.g. 150, 160, 170, 180, 190 and/or 200) is a diaphragm check
valve. A diaphragm check valve uses a flexing rubber diaphragm
positioned to create a normally-closed valve. Pressure on the
upstream side must be greater than the pressure on the downstream
side by a certain amount, known as the pressure differential, for
the check valve to open allowing flow. Once positive pressure
stops, the diaphragm automatically flexes back to its original
closed position.
[0035] However, it should appreciated that theses one-way valves
may be any other suitable check valve, clack valve, non-return
valve, reflux valve, or retention valve as long as it allows air to
flow through it in only one direction. In various embodiments,
each, of the above one-way valves (e.g. 150, 160, 170, 180, 190
and/or 200) may be a ball check valve (either spring-loaded or
not), or a similar check valve where the disc is not a ball, but
some other shape, such as a poppet energized by a spring. It may be
a swing check valve or tilting disc check valve in which the disc,
the movable part to block the flow, swings on a hinge or trunnion,
either onto the seat to block reverse flow or off the seat to allow
forward flow. It may also be a flapper valve, a clapper valve, a
backwater valve, a stop-check valve, a lift-check valve, an in-line
check valve, a duckbill valve, and the like.
[0036] In various embodiments, the distal one-way inhalation valve
150 and the distal one-way exhalation valve 160 are paired together
and built as a single valve assembly 300, as shown in FIG. 6. The
single valve assembly 300 may comprise (1) an integrated diaphragm
310 including an inhalation diaphragm portion 311 and an exhalation
diaphragm portion 312; (2) a distal member 320 including a seat 321
for the inhalation diaphragm portion 311 to sit on so as to seal
the inhalation lumen 130, and a gate 322 for receiving the
exhalation diaphragm portion 312 so as to open the exhalation lumen
140; and (3) a proximal member 330 including a gate 331 for
receiving the inhalation diaphragm portion 311 so as to open the
inhalation lumen 130, and a seat 332 for the exhalation diaphragm
portion 312 to sit on so as to seal the exhalation lumen 140. In
typical embodiments, the integrated diaphragm 310, the distal
member 320 and the proximal member 330 are secured together into
one functional part, either inside lumens 130/140 or extending from
lumens 130/140 and capable of communicate air thereto and
therefrom.
[0037] In a similar manner, the proximal one-way inhalation valve
170 and the proximal one-way exhalation valve 180 can be built as a
single valve assembly (not shown). Similarly, the assembly includes
(1) an integrated diaphragm including an inhalation diaphragm
portion and an exhalation diaphragm portion; (2) a distal member
including a seat for the inhalation diaphragm portion to sit on so
as to seal the inhalation lumen, and a gate for receiving the
exhalation diaphragm portion so as to open the exhalation lumen;
and (3) a proximal member including a gate for receiving the
inhalation diaphragm portion so as to open the inhalation lumen,
and a seat for the exhalation diaphragm portion to sit on so as to
seal the exhalation lumen. In typical embodiments, the integrated
diaphragm, the distal member and the proximal member are also
secured together into one functional part, either inside lumens
130/140 or extending from lumens 130/140 and capable of communicate
air thereto and therefrom.
[0038] In a similar manner, the anti-collapse one-way inhalation
valve 190 and the anti-collapse one-way exhalation valve 200 can
also be built as a single valve assembly (not shown). Similarly,
the assembly includes (1) an integrated diaphragm including an
inhalation diaphragm portion and an exhalation diaphragm portion;
(2) a distal member including a seat for the inhalation diaphragm
portion to sit on so as to seal the inhalation lumen, and a gate
for receiving the exhalation diaphragm portion so as to open the
exhalation lumen, and (3) a proximal member including a gate for
receiving the inhalation diaphragm portion so as to open the
inhalation lumen, and a seat for the exhalation diaphragm portion
to sit on so as to seal the exhalation lumen. In typical
embodiments, the integrated diaphragm, the distal member and the
proximal member are secured together into one functional part
inside lumens 130/140.
[0039] In various embodiments, the present invention provides a
method for reducing a volume of a respiratory dead space in a
snorkel. As shown in FIG. 7, the method includes:
[0040] step 701 of providing a mouthpiece or mask 110 for a
snorkeler to breathe air in and out;
[0041] step 702 of providing a tube 120 comprising an inhalation
lumen 130 and an exhalation lumen 140, wherein the tube 120 has a
distal end that is open to ambient air when the snorkeler is
snorkeling and a proximal end that is connected to the mouthpiece
or mask 110 for air to inhale into the mouthpiece or mask 110 from
the inhalation lumen 130 and to exhale from the mouthpiece or mask
110 to the exhalation lumen 140;
[0042] step 703 of placing a distal one-way inhalation valve 150
inside the inhalation lumen 130;
[0043] step 704 of placing a distal one-way exhalation valve 160
inside the exhalation lumen 140, and
[0044] step 705 of placing a proximal one-way inhalation valve 170
inside the inhalation lumen 130 and between the distal one-way
inhalation valve 150 and the mouthpiece or mask 110, and/or a
proximal one-way exhalation valve 180 inside the exhalation lumen
140 and between the distal one-way exhalation valve 160 and the
mouthpiece or mask 110.
[0045] As shown in FIG. 8, the method of the invention may further
include:
[0046] step 706 of preventing the inhalation lumen 130 and/or the
exhalation lumen 140 from collapsing or narrowing air passage due
to water pressure against tube 120 in snorkeling, for example,
placing one or more anti-collapse one-way inhalation valves 190
inside the inhalation lumen 130 and between the distal one-way
inhalation valve 150 and the proximal one-way inhalation valve 170,
and/or one or more anti-collapse one-way exhalation valves 200
inside the exhalation lumen 140 and between the distal one-way
exhalation valve 160 and the proximal one-way exhalation valve
180.
[0047] The snorkel of the invention may be either separate or
integrated into a swimming or diving mask. The integrated version
is only suitable for surface snorkeling, while the separate device
may also be used for underwater activities such as spearfishing,
freediving, fin-swimming, underwater hockey, and underwater rugby;
and for surface breathing with scuba equipment.
[0048] The snorkel of the invention may be bent into a shape often
resembling the letter "L" or "J", fitted with a mouthpiece at the
lower end and constructed of light metal, rubber or plastic. The
snorkel of the invention may come with a rubber loop or a plastic
clip enabling the snorkel to be attached to the outside of the head
strap of the diving mask. The snorkel may also be secured by
tucking the tube between the mask-strap and the head.
[0049] In a specific embodiment as shown in FIGS. 9, 10 and 11, a
snorkel 4 is equipped with a two-lumen breathing tube 5 and a valve
unit 6 (an embodiment of the above single valve assembly 300).
Snorkel 4 includes mouth wing 8, an inhalation breathing tube 9
with canal 27, and an exhalation breathing tube 10 with canal 28.
Valve unit 6 includes top cover 11 (an embodiment of the above
distal member 320), integrated diaphragm 12 (which can be of any
shape, e.g. butterfly-shaped), and proximal member 15.
[0050] Top cover 11 has two windows (25, 26) that one (26) is
larger than the other (25) and a central bridge which has one screw
hole 22 at the center. Integrated diaphragm 12 includes inhalation
diaphragm portion 13 and exhalation diaphragm portion 14, and a
screw hole 23 in between. Integrated diaphragm 12 may be butterfly
shaped and comprise one larger wing 14, one smaller wing 13, and
has a central screw hole 23 at the center. The smaller wing 13 of
butterfly-shaped valve is smaller than the smaller window 25 of top
cover 11, and larger wing 14 is smaller than the larger window 26
of top cover 11.
[0051] Proximal member 15 of valve unit 6 has a bottom view 16 as
shown in FIG. 11. A sectional view 18 of proximal member 15 through
dissection line 17 through the middle of proximal member 15 is also
shown in FIG. 11. Admitting hole 19a of proximal member 15 can
admit snugly breathing tube 9, and another admitting hole 19b of
proximal member 15 can admit snugly breathing tube 10. Inhalation
chamber 20 communicates with admitting hole 19a, and exhalation
chamber 21 communicates with admitting hole 19b.
[0052] Screw hole 22 of top cover 11 allows screw 7 to pass easily,
and screw hole 23 of integrated diaphragm 12 also allows screw 7 to
pass through easily. Screw 7 can pass easily through screw hole 22
and screw hole 23 to screw into threaded cannel 24 to fix top cover
11 and integrated diaphragm 12 onto body of proximal member 15 to
make valve unit 6.
[0053] Window of inhalation 25 is smaller than inhalation diaphragm
portion 13. Inhalation diaphragm portion 13 is smaller than
inhalation chamber 20. Therefore, inhalation diaphragm portion 13
can only bent downward by flush of inhalation breath of the
snorkeler. Exhalation chamber 21 is smaller than exhalation
diaphragm portion 14. Exhalation diaphragm portion 14 is smaller
than window of exhalation 26. Therefore, exhalation diaphragm
portion 14 can only be bent outward by flush of exhalation of the
snorkeler. Therefore, valve unit 6 provides one-way breathing
cycle.
[0054] Partition wall 29 divides proximal member 15 into two
chambers, i.e. chamber 20 and chamber 21. Partition 29 can stop
tube 5 and can prevent it from moving upward. When admitting hole
19a is connected to breathing tube 9 and admitting hole 19b is
connected to breathing tube 10, tube 5 provides one-way breathing
cycle to allow fresh air to be breathed in through window of
inhalation 25 to pass through canal 27 into snorkeler's lung and
the CO.sub.2 polluted air exhaled through canal 28 and window of
exhalation 26 into air. Therefore snorkeler who wears tube 5 always
inhales fresh air to prevent hypercapnia.
[0055] As shown in FIGS. 9 and 10, the J-shaped tube connects valve
unit 6 at its top and has a mouth biting piece built at the
up-turning shaped lower end. The mouth-biting piece may include an
oval-shaped wing 8 and a terminal portion of tubes 9 and 10 at
their proximal end.
[0056] Proximal member 15 comprises two equal chambers (20, 21),
one at the right side and the other at the left side, divided by a
central partition 29. One central threaded canal 24 is located at
the middle of the central partition 29. One figure of eight bottom
hole of proximal member 15 can admit the top of two channels
breathing tube (9, 10). Chamber 20/21 is larger than the smaller
wing 13 but smaller than larger wing 14. Therefore, smaller wing 13
can only bent inward into the chamber 20 and larger wing 14 can
only be bent outward. Screw 7 can pass through central screw hole
