Description
THE PRIOR ART
In the prior art of douching, the usual practice is to use a manual
syringe. This syringe, consists of a nozzle adapted for insertion
into the vagina. The other end of the nozzle is connected to a
suitable reservoir. The reservoir may comprise a bulb which is
squeezed by the user to discharge the douching fluid out of the
nozzle. In other cases, the nozzle is connected by a hose to a
douche bag which is mounted above the user, and the douching fluid
flows by gravity down the hose and into the nozzle.
Albeit simple and direct, these manual syringes are nevertheless
awkward, tiring, inefficient, and somewhat undesirable from a
cleansing standpoint. Moreover, at times, the manual method of
douching may involve relatively high pressures which are
uncomfortable and potentially dangerous to the user.
The prior art has also disclosed some power-operated vaginal
irrigating devices intended to improve upon the manual methods.
Generally, these devices are large, stationary and somewhat
cumbersome; or else involve several hoses together with a high
voltage electric cord, the latter being undesirable from a safety
standpoint. Hence these power-operated devices are not in current
widespread usage, and have not enjoyed commercial success in the
consumer market.
Moreover, the prior art, whether manual or powered, has habitually
resorted to a generally steady flow of the douching fluid, which is
not entirely satisfactory.
OBJECTS OF THE INVENTION
Accordingly, it is an object of the present invention to alleviate
the deficiencies of the prior art by providing a portable
power-operated douching appliance including oscillatory pumping
means for developing a pulsating flow of variable intensity or
velocity, whereby the douching fluid flows out of the nozzle means
and into the vagina in a series of interconnected fluid pulses,
thereby improving the cleansing efficiency while providing a
refreshing stimulation.
In accordance with the further teachings of the present invention,
the oscillatory pumping means includes a diaphragm which vibrates
at a frequency in the range of approximately 5 to 10 cycles per
second. The diaphragm is driven by an electromagnet, which in turn
is energized by a rechargeable battery mounted within the housing.
The battery and electromagnet are controlled by a switch which is
mounted on the housing, rearwardly of the nozzle, for convenient
manipulation by the user. Preferably, the reservoir comprises a
disposable hygienically sealed plastic bag having a frangible seal
and containing a predetermined amount of water-soluble douching
powder, while the nozzle means comprises a series of
interchangeable nozzle elements selectively mounted on the housing
by quick-disconnect means.
These and other objects of the present invention will become
apparent from a reading of the following specification, taken in
conjunction with the enclosed drawings.

DETAILED DESCRIPTION
With reference to FIG. 1, there is illustrated a portable
power-operated douching appliance 10 which may be conveniently held
in the user's hand. The appliance 10 has a housing 11 which may
comprise a pair of molded plastic, complementary mating halves 11a
and 11b suitably secured together and enclosing the
electromechanical components therebetween. A reservoir 12,
containing a quantity of douching fluid at a desired temperature,
is connected to the housing by means of a hose 13. A nozzle 14 is
mounted on the opposite end of the housing, and is adapted for
direct insertion into the vagina.
With reference to FIGS. 1 and 2, the housing includes an
electromagnet or solenoid comprising a core 15, a winding 16, and a
vibrating armature 17. The winding is energized by means of a
battery 18, which is rechargeable, and is controlled by means of a
switch 19. The wiring, being conventional, is omitted for ease of
illustration. The switch is mounted on the housing, above and
rearwardly of the nozzle, for convenient manipulation by the user
as she grasps the housing, FIG. 1., and inserts the nozzle into her
vagina.
With further reference to FIG. 2, the reservoir communicates with
the nozzle by means of a main fluid passage 20 formed within the
housing. A diaphragm 21, connected to one side of the vibrating
armature, is disposed within the passage and comprises an
oscillatory pumping means for the douching fluid. The diaphragm is
formed of a suitable material such as neoprene, and has its ends 22
and 23 bent (as shown) and hooked about respective lugs 24 and 25.
As hereinafter described, the bent end 23 of the diaphragm
comprises a first one-way check valve between the reservoir and the
passage 20, while the other bent end 22 comprises a second one-way
check valve between the passage and the nozzle.
When the switch 19 is closed, and electrical circuit is completed
from the battery 18 to the winding 16 through the normally closed
contacts 26 and 27 in a manner appreciated by those skilled in the
art. One of the contacts, 26, is stationary while the other contact
27 is mounted on an insulating member 26 for conjoint movement with
the vibrating armature 17. The armature is attracted to the winding
and core 15, compressing the springs 29, and causing a momentary
interruption between contacts 26, 27. During the attraction of the
armature and its attached diaphragm, a fluid pressure differential
is created between opposite sides of the bent end 23, that is, the
pressure within the fluid passage 20 is less than the pressure on
the reservoir side of the bent end 23. As a result, the bent end
23, which constitutes a one-way check valve between the reservoir
and the fluid passage means, flexes (as shown by the dotted lines
in FIG. 2) and douching fluid is admitted to the main fluid passage
20. Then, when the springs 29 are sufficiently compressed, the
spring force moves or repels the armature and diaphragm away from
the electromagnet. Thus, a reverse fluid pressure differential is
created, that is, the pressure in the main fluid passage 20 is
greater than the pressure on the nozzle side of the other bent tab
22, which constitutes a one-way check valve between the main fluid
passage 20 and nozzle. As a result, douching fluid is now
discharged or pumped out of the fluid passage 20, past the bent tab
22 (which flexes as shown by the broken lines in FIG. 2) and into
the nozzle 14 for application to the user. Further, the contacts
26, 27 are again closed, and the cycle is repeated as long as the
switch 19 is maintained in its closed position.
The vibrating diaphragm 21, driven by the electromagnet which in
turn is energized by the self-contained rechargable battery,
comprises an oscillatory pumping means for developing an irregular
or pulsating flow. During each cycle of operation, the douching
fluid flows out of the nozzle into the vagina in the general form
of a fluid pulse. However, since the diaphragm vibrates at a
substantial frequency (the preferred range being approximately 5 to
10 cycles per second) the fluid pulses are interconnected and merge
into one another; and as a result, the flow pulsates, that is, the
flow of douching fluid is characterized by a variable velocity or
intensity as distinguished from the continuous, substantially
uniform flow of a conventional centrifugal pump. As a result, the
cleansing efficiency is improved, and the user is provided with a
refreshing, invigorating stimulation.
With reference to FIGS. 3 and 4, there is illustrated a preferred
embodiment 10a of the portable power-operated douching appliance,
like numbers being used to denote structural elements similar to
those in FIGS. 1 and 2. The housing 11, which is adapted to be
conveniently held in the user's hand, is of the "clam shell" type
and comprises molded-plastic complementary mating halves 11a and
11b. The housing encloses the electromagnet comprising the core 15,
winding 16, and armature 17. The armature has the diaphragm mounted
thereon for conjoint movement therewith. The diaphragm comprises a
relatively thin sheet of flexible material, such as neoprene, which
is trapped between cooperating peripheral portions 30a and 30b
formed, respectively, in the complementary mating halves of the
"clam shell" housing. The material of the diaphragm is chosen for
its inherent flexibility, sealing qualities, and for being
impervious to the conventional douching fluids, that is, the
material of the diaphragm should not contaminate the douching fluid
with foreign particles that may be potentially harmful to the user,
and nor should the diaphragm itself be deteriorated by the douching
fluid and hence lose its desirable characteristics. Moreover, the
diaphragm is formed with slits 31 and 32; these slits, have a
function similar to the bent ends 22 and 23 of the FIG. 2
embodiment, and as hereinafter described in detail, constitute
first and second one-way check valves, respectively, for the
admission of douching fluid into the main fluid passage 20 and its
discharge therefrom into the nozzle.
With further reference to FIG. 4, the switch means 19 includes a
switch-operating lever 33 mounted on a boss 34 for pivotal
movement. The location of the lever 33 at the rearward top portion
of the housing, opposite to the nozzle means 14, allows the
appliance to be easily held in the user's hand and conveniently
manipulated. A first pair of leaf-spring contacts 35, 36 are
cantilever mounted on the housing by means of a screw 37. These
first contacts 35, 36 are normally open, as shown, and comprise the
switch contacts whose closure is effected upon manual actuation of
the switch lever 33. A second pair of leaf-spring contacts 38 and
39 are also cantilever mounted by the screw 37. These second
contacts 38, 39 are normally closed, as shown, with the contact 39
bearing upon the head of a screw 40 carried by the armature 17.
Each contact in the pairs 35, 36 and 38, 39 is insulated from the
other by a pair of shouldered insulating washers 41 and 42
respectively, positioned beneath the head of screw 37. The springs
29 bias the armature 17 away from the electromagnet, in the manner
as previously described with regard to the FIG. 1 embodiment of the
invention. The electromagnet, moreover, is preferably energized by
means of the self-contained rechargeable battery 18. The battery,
electromagnet, and contacts 35, 36, 38, and 39 are all connected in
series with each other; however the specific wiring, being
conventional, is omitted for ease of illustration.
With reference again to FIG. 4, and with further reference to FIG.
6, the hose 13 is slipped over the enlarged end 43 of an inlet tube
44 which is integrally mounted within the housing and projects
rearwardly therefrom. The tube 44 has a series of apertures 45
which communicate with an inlet canal 46 molded within the top half
11a of the "clam shell" housing, the bottom of the inlet canal 46
being sealed by the diaphragm 21.
With reference to FIGS. 4 and 7, the diaphragm 21 is further
supported towards the rearward portion of the housing by means of
first cooperating internal ledges 47 and 48 formed, respectively,
in the complementary mating halves 11a and 11b inwardly of the
peripheral clamping portions 30a and 30b. Between these cooperating
pairs of clamping portions, the diaphragm is apertured by the thin
slit 32, the thickness of which is somewhat exaggerated in the
drawings for ease of illustration. Likewise, the diaphragm is
further supported towards the front of the housing by means of
second cooperating internal ledges 49 and 50, with another slit 31
being formed in the diaphragm forwardly of the ledges 49 and 50.
The main fluid passage 20, see FIG. 4, is integrally molded or
cored within the bottom half 11b of the housing, with the diaphragm
providing the sealing cover therefor.
With reference to FIG. 4 and 8, the top housing half 11a is molded
or formed with an outlet channel 51 disposed above the slit 31, and
the outlet channel 51 communicates with a vertical canal 52 leading
to a recess 53. The recess 53 is counterbored and formed with
internal threads 54 to provide a quick-disconnect coupling with the
threaded end 55 of nozzle means 14.
The operation of the FIG. 4 embodiment of the present invention is
similar to that described herein for the FIG. 1 embodiment. When
the switch lever 33 is depressed, thereby closing the normally open
switch contacts 35 and 36, the winding 16 is energized by the
battery 18, and the armature 17 and its attached diaphragm 21 are
alternately attracted to, and repelled away from, the
electromagnet. The head of screw 40, which is carried by the
armature, repeatedly interrupts the normally closed contacts 38 and
39. The springs 29 return the armature to its original position,
re-establishing closure of the contacts 38 and 39, and the cycle is
repeated as long as the switch lever 33 is maintained in its
depressed position.
With reference to FIG. 5a, when the armature and diaphragm are
attracted towards the electromagnet, a fluid pressure differential
is created, that is, the fluid pressure in the inlet canal 46 is
greater than that in the main fluid passage 20; and the slit 32 in
the diaphragm opens sufficiently to admit douching fluid into the
passage 20 as shown by the small arrows in FIG. 5a. Conversely,
when the armature and diaphragm are repelled by the spring force
away from the electromagnet, the fluid pressure in passage 20 is
greater than that in outlet channel 51, and slit 31 in the
diaphragm opens sufficiently to discharge the douching fluid into
the outlet channel 51 and ultimately into the nozzle means 14, as
shown by the small arrows in FIG. 5b. As shown on the drawings,
each of the slits 31 and 32, when opened by the fluid pressure,
constitutes a flap which opens, away from its ledge 30b and 47,
respectively, and when closed, seats or seals against its
respective ledge.
In operation, douching fluid is discharged out of the nozzle in a
series of interconnected fluid pulses, thereby creating a pulsating
flow of variable velocity or intensity. The discharge pressure of
the douching fluid out of the nozzle is preferably equivalent to
that developed by a conventional douche bag (of the gravity flow
type) which is held approximately 2 feet above the nozzle.
Experience has shown that a higher discharge pressure may be
uncomfortable and possible harmful to the user, particularly if the
douching fluid would be forced up into the uterus. This can often
happen with the prior art douche bag, which the user invariably
hangs on any convenient support without especial regard for the
height above the nozzle. Since the height governs the discharge
pressure, an uncomfortable and perhaps dangerous condition may be
experienced in using the conventional douche bag. On the other
hand, the present invention has the assurance that douching will
not be potentially harmful, while at the same time enjoying the
benefits and comforts derived from a small portable appliance which
is power-operated and convenient to use.
With reference to FIG. 9, the end of the hose 13 is retained within
a molded plastic cap 56. This cap is pushed into a plastic collar
57 which is heat sealed, as at 59, to the reservoir means 12. The
cap 56 and collar 57 are held together by means of respective
cooperating protrusions 58a and 58b, which provide a "snap" fit.
Preferably, the reservoir means comprises a disposable plastic bag
60 of polyolefin (or other suitable material) and is adapted to
receive approximately 1 pint of douching fluid at a desired
temperature. The disposable bag 60 may contain a predetermined
quantity of douching powder, and may be hygienically sealed. The
seal, however, is frangible and may be easily broken, as at 61, by
the irregular edges 62 formed at the bottom of the cap 56.
Otherwise, the seal may be broken by the finger, by the faucet, or
by any suitable instrument. Once the seal is broken, the water may
fill the bag to dissolve the powder, and the appliance is ready for
use.
The battery-operated douching appliance 10 may be conveniently
supplied to the user in kit form together with several bags 60,
each of which contains the proper douching powder, and is
hygienically sealed and folded. The kit may also include a variety
of nozzles, such as the nozzles 63, 64 and 65 shown in FIG. 10.
These nozzles provide a variety of sizes and shapes and may be
formed with a convoluted end, as at 66 for nozzle 65. Each nozzle
has side apertures, as at 67, so that the douching fluid is
suitably sprayed, laterally, for irrigation of the vagina by means
of the pulsating variable-velocity flow of the present
invention.
Moreover, one or more of the nozzles may be made from a plastic
material which, while being sufficiently rigid, may nevertheless be
somewhat pliable and adapted to expand and contract slightly as a
result of the pulsating flow of douching fluid.
Obviously, many modifications may be made without departing from
the basic spirit of the present invention. For example, the
armature could be made of a magnetized material and could be
repelled by electromagnet, while the springs could be arranged to
urge the armature and its diaphragm towards the electromagnet.
Thus, within the scope of the appended claims, the invention may be
practiced other than has been specifically described therein.
