DETAILED DESCRIPTION
Overview
[0005] The present description relates to hand-operable vacuum
devices. In some cases, hand-operable vacuum devices can be
manipulated by a user to draw material (e.g., solid, liquid, gas)
into the device and/or expel material from the device. In some
cases, hand-operable vacuum devices can be used to create a vacuum
force or suction without necessarily drawing material into the
device, and/or to pressurize gases or liquids within the device.
The hand-operable vacuum device can be constructed such that a user
can squeeze and deform the device and then the device is
resiliently biased to return to an original configuration. The
construction of the hand-operable vacuum device can include
generally longitudinally arranged resilient outwardly-biasing
structures that bias the device back to its original configuration
more effectively than existing technologies. This effective bias
can create relatively strong vacuum forces for drawing material
into the hand-operable vacuum device.
Examples
[0006] FIGS. 1-11 collectively show an example of a hand-operable
vacuum device 100. FIGS. 1, 3, and 5 show the hand-operable vacuum
device 100 in a first configuration. FIGS. 2, 4, and 6 show the
hand-operable vacuum device 100 manipulated into a second
configuration by a human user. FIGS. 7-11 collectively show how the
construction of the hand-operable vacuum device 100 promotes
returning to the first configuration of FIGS. 1, 3, and 5 when the
user stops manipulating the device. Briefly, the hand-operable
vacuum device 100 can be resiliently biased to assume and/or return
to the first configuration after user manipulation.
[0007] FIGS. 1 and 2 show perspective views of the hand-operable
vacuum device. FIGS. 3-4 show sectional views of the hand-operable
vacuum device taken along section AA indicated in FIG. 1. Section
AA is transverse to the x-reference axis and parallel to the
yz-reference plane. FIGS. 5-6 show a component of the hand-operable
vacuum device taken parallel to the xz-reference plane as indicated
along section BB.
[0008] In some cases, the hand-operable vacuum device 100 can be
thought of as having a deformable portion 102 and an interface
portion 104 that can include a nozzle 105. The deformable portion
102 can extend along a long axis that runs parallel to the
x-reference axis. The deformable portion can be generally
elongated, spherical, or other shape. The deformable portion can
include one or more resilient outwardly-biasing structures 106. In
some implementations the resilient outwardly-biasing structures can
be longitudinally oriented (i.e., parallel to the long axis). In
this case, the hand-operable vacuum device includes a pair of
resilient outwardly-biasing structures 106(1) and 106(2).
[0009] The deformable portion 102 can be manipulated or squeezed by
a user as indicated by arrows 402 and 404 to deform or squish the
deformable portion. The squishing can bend the resilient
outwardly-biasing structures as can be seen by comparing FIGS. 5
and 6 which show resilient outwardly-biasing structure 106(1). FIG.
5 shows the resilient outwardly-biasing structure in a resting or
biased configuration. FIG. 6 shows a bowed configuration of the
resilient outwardly-biasing structure produced by user
manipulation.
[0010] FIGS. 7-11 show how the resilient outwardly-biasing
structures 106(1) and 106(2) can return the deformable portion 102
to the resting configuration when the user stops applying pressure.
Specifically, upward arrows 702(1) and 702(2) indicate the outward
bias exerted by resilient outwardly-biasing structures 106(1) and
106(2), respectively. The outward bias returns the resilient
outwardly-biasing structures from the bowed configuration of FIG. 8
to the more linear configuration of FIG. 9. (In another
implementation, the resilient outwardly-biasing structures could be
outwardly bowed at rest such that user manipulation causes them to
be less bowed.) The outward bias exerted by resilient
outwardly-biasing structures 106(1) and 106(2) facilitates
returning the deformable portion from the manipulated configuration
of FIG. 10 to the resting configuration of FIG. 11. Returning the
deformable portion to the resting configuration can increase the
volume thereof and can thereby create a very strong vacuum that can
be utilized to draw material into the interface portion 104 via
nozzle 105.
[0011] FIG. 12 illustrates an example of how the resilient
outwardly-biasing structures 106(1) and 106(2) can extend from a
perimeter 1202 of the deformable portion 102. In various
implementations the resilient outwardly-biasing structures can
extend from the perimeter at an angle .alpha. that is oblique or a
right angle relative to the perimeter proximate to the
outwardly-biasing structure. In some implementations, the angle
.alpha. can be in a range from about 90 degrees to about 135
degrees. Other implementations may be outside this range.
[0012] The example implementations above include a pair of
outwardly-biasing structures 106(1) and 106(2). FIGS. 13-14
illustrate some alternative implementations of hand-operable vacuum
devices.
[0013] FIG. 13 shows first and second pairs of outwardly-biasing
structures 1302(1), 1302(2) and 1304(1), 1304(2) on deformable
portion 1306. In this example the first and second pairs are
generally opposing one another, but such need not be the case.
However, the present example can be useful in facilitating the
user's grip.
[0014] FIG. 14 shows an alternative implementation that includes
three outwardly-biasing structures 1402(1), 1402(2), and 1402(3) on
deformable portion 1404. In this case the outwardly-biasing
structures extend outwardly from perimeter 1406 rather than
inwardly as illustrated in the example implementations of FIGS.
1-13.
[0015] FIG. 15 offers another implementation with two
outwardly-biasing structures 1502(1) and 1502(2) on deformable
portion 1504. In this case, the outwardly-biasing structures are
generally elliptical rather than linear when viewed in
cross-section. Other shapes and/or configurations can alternatively
or additionally be utilized.
[0016] FIG. 16 shows an example hand-operated vacuum device 1600
that can be employed as a specimen collector, among other uses.
[0017] FIG. 17 shows an example hand-operated vacuum device 1700
that can be employed as a throat aspirator, among other uses.
[0018] FIG. 18 shows an example hand-operated vacuum device 1800
that can be employed as a dental squirt pick, among others.
[0019] FIG. 19 shows an example hand-operated vacuum device 1900
that can be employed as a nose aspirator, among others.
[0020] FIGS. 20-21 collectively show another example of a
hand-operated vacuum device 2000 that can be employed to various
uses. In this case, the hand-operated vacuum device 2000 includes
deformable portion 2002 and interface portion 2004. The deformable
portion 2002 includes resilient outwardly-biasing structures
2006(1) and 2006(2). The interface portion 2004 includes a
removable cap 2008 that covers a nozzle 2010.
[0021] FIG. 20 shows the removable cap 2008 in place on the
interface portion 2004. FIG. 21 shows the hand-operated vacuum
device 2000 with the cap removed to expose nozzle 2010. The
removable cap 2008 can be formed during manufacture of the
hand-operated vacuum device 2000 and/or added to the hand-operated
vacuum device. For instance, the removable cap can be formed as
part of the hand-operated vacuum device to help maintain internal
conditions of the hand-operated vacuum device. For instance, the
removable cap could be utilized to maintain sterile conditions in
the hand-operated vacuum device until the cap is removed at the
time of use. The user can remove the removable cap, such as by
twisting. The user can then squeeze the deformable portion and
place the nozzle 2010 near a sample to be collected. The user can
reduce and/or release the pressure on the deformable portion to
create a vacuum that draws the sample into the hand-operated vacuum
device. In some implementations, the removable cap 2008 can be
re-installed to maintain the sample and avoid
cross-contamination.
[0022] In other configurations, the hand-operated vacuum device
2000 can be manufactured and filled with a liquid, such as a wound
cleansing antiseptic solution or a mouthwash. The removable cap can
then be added to maintain the integrity of the liquid until use. A
user can remove the removable cap and propel the liquid from the
nozzle by squeezing the deformable portion 2002.
[0023] FIGS. 22-25 collectively show an example hand-operated
vacuum device 2200 that can be employed as a vacuum pump, among
other uses. For example, hand-operated vacuum device 2200 can be
employed as a penis pump and/or vacuum constriction device, such as
used with respect to erectile dysfunction. In this example, the
hand-operated vacuum device 2200 can be employed to create
relatively strong vacuum forces, but not necessarily to draw
material into the hand-operable vacuum device. In this case, the
hand-operated vacuum device 2200 includes deformable portion 2202
and interface portion 2204. The deformable portion 2202 includes
resilient outwardly-biasing structures 2206(1) and 2206(2). The
hand-operated vacuum device 2200 can also include a nozzle 2210, a
vent 2212, ridges 2214, and a constriction ring 2216 (not all
ridges 2214 are labeled to avoid clutter on the drawing page).
[0024] FIG. 24 shows a sectional view of hand-operable vacuum
device 2200 taken along section CC indicated in FIG. 22. Section CC
is transverse to the x-reference axis and parallel to the
yz-reference plane. At least part of the interface portion 2204 of
hand-operated vacuum device 2200 can have a generally circular
cross-sectional shape, as shown in FIG. 24, for example. The
deformable portion 2202 of hand-operated vacuum device 2200 can
have a cross-sectional shape similar to the deformable portion of
hand-operated vacuum device 100 shown in FIG. 3.
[0025] In some implementations, the vent 2212 can be an alternative
opening to the nozzle 2210 for air to flow in and out of the
hand-operated vacuum device 2200. The vent 2212 can be
ergonomically positioned on the hand-operated vacuum device 2200
such that a user can place their thumb or finger over the vent
2212. The ridges 2214 can provide friction to make the
hand-operated vacuum device 2200 easier to grasp by the user. The
constriction ring 2216 can be a separate part. The constriction
ring can be designed with a size and shape such that the
constriction ring lies flush against an outer end of the nozzle
while the hand-operated vacuum device 2200 is being used. Other
shapes and/or configurations of vents, ridges, and/or constriction
rings can alternatively or additionally be utilized.
[0026] The hand-operated vacuum device 2200 can be made in a
variety of sizes. For example, the hand-operated vacuum device 2200
could be offered in relatively "small," "medium," and "large"
sizes. The sizing of the hand-operated vacuum device 2200 can
correspond to a diameter of the nozzle 2210 and/or the constriction
ring 2216. For instance, an outer diameter of the constriction ring
can range from approximately 13/8 inches to 15/8 inches for the
various sizes, while an inner diameter of the constriction ring can
range from 13/16 inches to 11/8 inches. An overall length of the
hand-operated vacuum device 2200 can also vary accordingly. Other
dimensions and/or sizing options are contemplated for the various
hand-operated vacuum devices.
[0027] FIGS. 26-28 collectively show an example hand-operated
vacuum device 2600 that can be employed as a dental squirt pick,
among other uses. In this case, the hand-operated vacuum device
2600 includes deformable portion 2602 and interface portion 2604.
The hand-operated vacuum device 2600 can also include a nozzle
2610. In this example, the deformable portion 2602 can have a
transition section 2618. Hand-operated vacuum device 2600 can also
include and a transition interface 2620. The transition interface
2620 will be described below relative to the example implementation
shown in FIG. 29.
[0028] In some implementations, when employed as a dental squirt
pick intended for use by an adult, an overall length of
hand-operated vacuum device 2600 can be approximately 6 inches from
an end of the deformable portion 2602 to a far end of the nozzle
2610. Where the hand-operated vacuum device is intended for use a
dental squirt pick by a child, the overall length could be less
than that intended for use by the adult, such as eighty percent
less, or approximately 5 inches. Other lengths and/or other
dimensions are contemplated.
[0029] FIG. 29 shows an example hand-operated vacuum device 2600(A)
that includes elements that are similar to hand-operated vacuum
device 2600. Hand-operated vacuum device 2600(A) can be
manufactured as multiple pieces. For example, interface portion
2604(A) can be removably secured to deformable portion 2602(A)
using transition interface 2620(A). In this case, the interface
portion 2604(A) can include a rim 2922 and an insert portion 2924.
The insert portion 2924 of the interface portion 2604(A) can slide
into a top end of the transition section 2618(A) of the deformable
portion 2602(A). The rim 2918 can seat against a top face of the
transition section 2618(A) and thereby limit how far the interface
portion 2604(A) extends into the deformable portion 2602(A). The
transition interface 2620(A) can be placed down over the interface
portion 2604(A). An exterior of the transition section 2618(A) can
include threading (shown but not designated) that coordinates with
threading on an interior of the transition interface 2620(A) to
secure the interface portion 2604(A) to the deformable portion
2602(A) using the transition interface 2620(A). Other shapes and/or
configurations of nozzle interfaces and/or attachment methods can
alternatively or additionally be utilized.
[0030] FIGS. 30-32 collectively show an example hand-operated
vacuum device 3000 that can be employed as an extractor, among
other uses. For instance, the extractor could be used to extract
blackheads, pimples, ticks, and/or splinters. In this case, the
hand-operated vacuum device 3000 includes interface portion 3004,
nozzle 3010, and transition interface 3020. In this example, the
interface portion 3004 is angled such that nozzle 3010 extends away
from a central long axis of the hand-operated vacuum device that is
parallel to the x-reference axis and passes through a center of the
transition interface 3020. In this instance, the nozzle 3010
extends further from the central long axis than an outwardly-facing
edge (e.g., outer circumference, outer diameter) of the transition
interface 3020. Additionally, in this example, the nozzle 3010 is
angled away from the x-reference axis in a direction that is
parallel to the y-reference axis. Other directions that the nozzle
is angled and/or other amounts that the nozzle is extended from the
central long axis can alternatively be utilized.
[0031] FIGS. 33-35 collectively show an example hand-operated
vacuum device 3300 that can be employed as a cell collector, such
as for Pap smears, among other uses. In this case, the
hand-operated vacuum device 3300 includes interface portion
3304.
[0032] FIGS. 36-38 collectively show an example hand-operated
vacuum device 3600 that can be employed as a cell collector, such
as for Pap smears, among other uses. In this case, the
hand-operated vacuum device 3600 includes interface portion 3604.
In this example, the interface portion 3604 is shorter than the
interface portion 3304 of hand-operated vacuum device 3300 shown in
FIGS. 33-35. Different lengths for interface portions of
hand-operated vacuum devices are contemplated. Additionally,
hand-operated vacuum devices can be offered in a variety of sizes
that correspond to varying interface portion lengths. Note that in
some cases, the length of the interface portion can vary amongst
different size options while dimensions of other portions of the
hand-operated vacuum devices remain the same.
[0033] FIGS. 39-41 collectively show an example hand-operated
vacuum device 3900 that can be employed as a nose aspirator, among
other uses.
[0034] FIGS. 42-44 collectively show an example hand-operated
vacuum device 4200 that can be employed as a portable bidet, among
other uses.
[0035] FIGS. 45-47 collectively show an example hand-operated
vacuum device 4500 that can be employed as a breast pump or a
travel breast pump, among other uses. The hand-operated vacuum
device 4500 includes a deformable portion 4502, an interface
portion 4504, a vent 4512, a transition section 4518, and a
transition interface 4520. In this example, the transition section
4518 and the transition interface 4520 can have threading (shown
but not designated). The threading and transition interface 4520
can be used to secure the deformable portion 4502 to the interface
portion 4504 similar to the example hand-operated vacuum device
2600A shown in FIG. 29.
[0036] FIGS. 48-50 collectively show an example hand-operated
vacuum device 4800 that can be employed as a throat aspirator,
among other uses. Hand-operated vacuum device 4800 can include a
vent 4812. In this example, a vent cap 4814 can also be
included.
[0037] Hand-operated vacuum devices can be manufactured utilizing
various techniques and/or materials. For instance, in some
implementations the hand-operated vacuum devices can be formed via
a molding process, such as injection molding or blow molding.
Various materials can be utilized including but not limited to
various polymers. In some cases, a portion of a hand-operated
vacuum device can be made from a different material than another
portion. For instance, the interface portion can be made from a
hard plastic. In another instance, referring to hand-operated
vacuum device 4500 shown in FIGS. 45-47, all or part of the
interface portion 4504, including the transition interface 4520,
can be made from silicone, while the deformable portion, including
the transition section 4518, can be made from a polymer, for
example. In still another instance, referring to hand-operated
vacuum device 2200 shown in FIGS. 22-25, the constriction ring 2216
can be made from rubber, for example.
[0038] In some cases the hand-operated vacuum devices can be
manufactured as a single piece, yet the interface portion can be
thicker than the deformable portion so that the interface portion
is relatively rigid while the deformable portion is readily
deformed by a user. For instance, such a configuration can be
achieved by blow molding where the polymer is introduced at the
interface end of the hand-operated vacuum device. In one such
example, the deformable portion can have an average thickness of
0.1-0.3 millimeters while the interface portion has an average
thickness of 0.3-0.6 millimeters. In other examples, the
hand-operated vacuum devices can be manufactured as multiple
pieces.
[0039] In summary, hand-operable vacuum devices are described that
can allow great vacuum (and/or expulsion) forces to be created by a
user. The hand-operable vacuum devices can be inexpensively
manufactured and can be disposable and/or reusable. In some
instances, the hand-operable vacuum devices can be manufactured
and/or packaged so that the devices are sterile until the packaging
is opened. Further, the hand-operable vacuum devices lend
themselves to construction from materials that can be transparent
so that the user can see the contents (if any).
Conclusion

be understood that the subject matter defined in the appended
claims is not intended to be limited to the specific features
described. Rather, the specific features are disclosed as exemplary
forms of implementing the claimed statutory classes of subject
