Description
BACKGROUND OF THE INVENTION
This invention relates to medical instruments and more particularly
to a throat irrigator for fluid connection to a source of pulsating
pressurized fluid to provide fluid for discharge from the irrigator
to wash tonsils and adjacent areas of the throat.
Until recently, the standard treatment for inflamed tonsils
(commonly called tonsillitis or, more accurately, acute follicular
tonsillitis, epidemic streptococcic tonsillitis and chronic
tonsillitis) was to remove the tonsils surgically by performing a
tonsillectomy. Recently, the advisability of tonsillectomies in
many cases of inflamed tonsils has been questioned, and other
methods of treating inflamed tonsils are now being used. One method
currently being used is to treat the inflamed tonsil with
antibiotics. However, this method is not always totally effective
because some of the bacteria which cause tonsillitis have developed
a resistance to these antibiotics. Additionally, the use of
antibiotics for the treatment of relatively minor ailments such as
tonsillitis is discouraged because there is evidence that the
widespread use of antibiotics to treat minor ailments develops
bacteria which are immune to antibiotics, making the antibiotics
less effective when needed for treating more serious ailments.
The bacteria that cause tonsillitis are not only in the tonsil
tissue, but are located on the surface of the tonsils as well. The
surface of a typical tonsil is composed of from 12 to 20 crypts or
openings which are many times, and quite normally, plugged with
visible debris or pus. It is in these openings or crypts that the
bacteria lodge to inflame the tonsils, and cause tonsillitis. Any
bacteria in the tonsil crypts may be removed therefrom simply by
washing the tonsil.
A common method of treatment of tonsillitis before the availability
of antibiotics and anesthetics made tonsillectomies customary
prescribed washing of the inflamed tonsils. Generally the washing
method of treating tonsillitis included the steps of filling a
suitable container such as a douche bag with a saline solution,
inserting a hose from the bag into the mouth, holding the bag over
the head, and directing the stream of the saline solution onto the
inflamed tonsil to wash the debris, pus and bacteria from the
crypts. In order to prevent the saline solution from choking the
patient or from being swallowed, the head of the patient was
usually positioned horizontally over a basin, allowing the solution
and the debris or pus and bacteria to drain downwardly through the
open mouth into the basin. This method of treatment has been fairly
effective, but the supply of saline solution held in a suitable
container such as a douche bag was limited, and the steady stream
of solution against the inflamed tonsil wasted much of the
solution. Many times the washing had to be repeated several times a
day to clean out all of the debris and pus from all of the
crypts.
More recently, units have been developed for delivering pulsating
pressurized water to the mouth for cleaning particles of food, etc.
from between the teeth and from the gums. These units, marketed
under the trademark "Water Pik" and other trademarks, have become
readily available to the general public. These units have a supply
of water which is plusatingly pressurized and is fed through a hose
to a hand held nozzle which directs the discharge of the
interrupted stream of water onto the teeth, to clean them. I have
found that such a unit is a very effective source of fluid or
saline solution for washing the tonsils and adjacent areas of the
throat. However, for washing tonsils, a suitable throat irrigator
must be provided, as the nozzle supplied with such unit is not
suitable for delivering the pulsating fluid stream to areas of the
throat, such as the tonsils.
BRIEF DESCRIPTION OF THE INVENTION
Therefore it is the primary object of this invention to provide a
novel throat irrigator for fluid connection to a source of
pulsating pressurized fluid, and for insertion into the mouth to
wash a tonsil and adjacent areas of the throat.
Other and additional objects of this invention are to provide such
a throat irrigator which is equally adapted for washing either
tonsil, to provide such a throat irrigator which rests on the
tongue to depress it, while providing a pivot for directing the
nozzle thereof across the tonsil, to provide such a throat
irrigator which seats the thumb to guide the pivoting of the
irrigator, to provide such a throat irrigator which is manually
graspable and rotatable to move the nozzle end of the throat
irrigator for moving the discharging fluid stream over desired
areas of the throat, to provide such a throat irrigator which is
effective to wash the debris, pus and bacteria from the crypts of
inflamed tonsils, and to provide such a throat irrigator which is
economical to manufacture, easy to install on a flexible tube from
a commercially available source of pulsating pressurized fluid,
easy to use, and effective to clean the crypts of the tonsils and
adjacent areas of the throat.
Generally, the throat irrigator according to this invention
includes conduit means for carrying pulsating fluid into the mouth
and to the throat, with the inner end thereof discharging the fluid
towards the throat, means on the outer end for fluidly connecting
the conduit means to a flexible tube, tongue depressor means on the
conduit means for the depressing of the tongue upon insertion of
the conduit means into the mouth, and control or guide means on the
conduit means for facilitating the manual movement of the conduit
means to direct the discharge of water towards the desired areas of
the throat. The throat irrigator may include a nozzle on the inner
end of the conduit means, upper and lower curved surfaces of
longitudinally bowed plates or a block, acting alternatively, as
tongue depressor means or manual moving means, and an enlarged
collar or sleeve fixed to the conduit means to further facilitate
manual grasping and rotating of the throat irrigator.
The present invention also contemplates a method for washing areas
of the throat, such as for treating tonsillitis by flushing the
crypts of the tonsils. Such method generally includes the steps of
fluidly connecting a throat irrigator to a source of pulsating
pressurized fluid, grasping the irrigator with a thumb on the thumb
seat, inserting the irrigator into the mouth, resting the tongue
depressor on the tongue to position the inner end of the nozzle
towards the tonsil, downwardly orienting the open mouth, energizing
the source of pulsating pressurized fluid, and moving the irrigator
to direct the flow of pulsating water into the crypts of a tonsil
to wash them. The method may include the steps of rotating the
irrigator, replacing the thumb or a finger on the thumb seat,
repositioning the tongue depressor on the tongue, and moving the
irrigator to direct the flow of water into the crypts of the other
tonsil.

DETAILED DESCRIPTION
Referring now to the drawings and particularly to FIG. 1, a typical
bathroom scene is shown. Such a bathroom scene normally includes a
conventional basin 10 extending from the bathroom wall 11, and also
extending from the wall 11 is a shelf 12. A source 13 of pulsating
pressurized fluid, which is commercially sold as a unit under a
number of trademarks, for example "Water Pik," is on shelf 12. An
electrical cord 14 runs from the unit 13 to an electrical outlet
(not shown) to provide power to the unit 13. A flexible hose 15 has
one end fluidly connected to the unit 13 and the other end attached
to a throat irrigator indicated generally at 20.
Referring now to FIG. 4, the throat irrigator 20 is in fluid
connection with the end of hose 15, and is inserted into the user's
mouth 21 past the lips 22 to rest on the tongue 23. Upon energizing
of the unit 13, the throat irrigator 20 will provide a pulsating
stream or jet of fluid to areas of the throat 24, such as a tonsil
25. The pulsations of the stream will wash the crypts or openings
26 in the surface of the tonsil 25. The throat irrigator 20
according to this invention may also supply the pulsating stream of
fluid to adjacent areas of the throat, such as for example the
adenoids 27 or the pharynx 28.
As best seen in FIG. 2, the throat irrigator 20 includes conduit
means indicated generally at 30 for carrying pulsating fluid into
the mouth 21 and to the throat 24, fluid connecting means indicated
generally at 40 on the outer end of the conduit means 30 for
fluidly connecting the conduit means 30 to the flexible hose 15,
tongue depressor means indicated generally at 50 on the conduit
means 40 for resting on and depressing the tongue 23 upon insertion
of the conduit means 30 into the mouth 21, and control or guide
means indicated generally at 60 on the conduit means 30 for
facilitating the manual movement of the conduit means 30 to assist
in controlling the discharge of the pulsating stream of fluid
across the area of the throat to be washed. The control or guide
means 60 may include grasping and rotating means 61 in the form of
an enlarged collar or sleeve against which the user's little or
ring finger may rest as the user grasps and manipulates the
device.
The conduit means 30 for carrying the pulsating fluid from the tube
15 into the user's mouth includes an outer end 31, a central
tubular portion 32 and an inner end 33 terminating in a discharge
nozzle 34 at an axis substantially perpendicular to the axis of
conduit 30. A central passage 35 extends from the outer end 31,
through the central tubular portion 32 to the inner end 33, to open
at the nozzle 34 for conducting the fluid through the conduit means
30.
The connecting means 40 for fluidly connecting the conduit 30 to
the open end of the flexible hose 15 is also best seen in FIG. 2,
and includes the provision of a chamfer 41 on the outer end 31 of
the conduit means 30; a circumferential groove 42 around the
conduit means 30, adjacent the chamfer; and a shank portion 43
around which the hose 15 extends. The open end of hose 15 slides
over the chamfer 41 and over the shank portion 43. The natural
resilience of the hose 15 depresses a portion of it into the
circumferential groove 42 to secure the hose 15 to the conduit
means 30 despite the pressure of the pulsating fluid on the
juncture therebetween.
Tongue depressor means 50 previously mentioned provides a pair of
outwardly concave curved surfaces symmetrically disposed about a
central plane which desirably includes the axis of conduit 30 and
the axis of nozzle 34. In FIG. 3a such means 50 are shown as
including a pair of longitudinally bowed plates 51, 52 having
outwardly concave surfaces 53, 54. Plates 51, 52 are fixed to
conduit 30 by suitable means such as an adhesive or by being molded
integrally with the conduit means 30 when the entire structure is
formed of one of many plastic materials, as is preferred.
Depending upon whether the right or left tonsil is being treated in
accordance with the present invention, one of the plates, such as
51, serves as a rest or seat for the finger or thumb of the user,
and the other plate then serves as a tongue depressor proper. In
treating the other tonsil, the user merely rotates irrigator 20
through 180.degree. about its own axis, whereupon the functions of
the plates 51, 52 and their outwardly concave curved surfaces 53,
54 are reversed, as will be readily understood.
Another form of the tongue depressor is shown in FIG. 3b, where
parts of the depressor are indicated by reference characters 100
greater than corresponding parts of FIG. 3a. Thus the tongue
depressor indicated generally at 150 in FIG. 3b includes a solid
block 156 desirably of plastic material fixed to conduit 30 by
suitable adhesive means or by being molded integrally therewith.
Block 156 has upper and lower portions 151, 152, each presenting
outwardly concave curved surfaces 153, 154 respectively. As in the
form shown in FIG. 3a, the curved surfaces are symmetrically
disposed about a central plane which includes the axis of conduit
30 and the axis of nozzle 34. Block 156 may have gently concaved
side walls 157, 158 merging smoothly with the upper and lower
concave surfaces 153, 154. Under certain conditions the form of the
invention shown in FIG. 3b may be desired, since its construction
facilitates cleaning of the device, and minimizes the possibility
that foreign matter might adhere to recessed portions of the
device.
Use of the irrigator in accordance with the present invention will
be now described with reference to FIGS. 1, 4 and 5. Thus the user
grasps the irrigator with either his thumb or index finger (the
thumb may be considered to be one of the fingers for present
purposes) resting on one of the surfaces 51, 52, and his little or
ring finger resting against collar 61, his remaining finger or
fingers curled around the central portion of the irrigator. He then
inserts the nozzle end of the irrigator into his mouth with the
other of the surfaces 51, 52 resting on and depressing the crown of
the tongue, and with the outlet opening of nozzle 34 directed to
one of the tonsils. He then bends over a basin or other receptacle
for used water or other washing solution, actuates the source unit
13, and adjusts the direction of jetting fluid from the nozzle as
desired. Typically the user oscillates the device slightly, both
longitudinally and rotationally, in order to direct the jetting
discharge from the nozzle to the entire exposed surface of the
tonsil and adjacent areas of the throat to be washed.
Treatment of the opposite tonsil and adjacent areas of the throat
is readily accomplished by the user's rotating of the irrigator
through 180.degree. about its own axis, repositioning the lower of
the curved surfaces 53, 54 laterally in the mouth, and then
adjusting the position and direction of the nozzle axis as
previously described.
An important advantage of the throat irrigator 20 according to this
invention is that it may be used by the patient in his home, thus
freeing space in hospitals and doctors' offices for the treatment
of more serious health problems. Simlarly an advantage of using the
throat irrigator according to this invention is that a person can
treat himself at the first signs of tonsillitis, thereby halting
the condition, and effectuating a rapid recovery. If a person so
desires, he can periodically wash his tonsils in accordance with
the present invention, much as he periodically brushes his teeth,
to prevent tonsillitis.
Thus the throat irrigator according to this invention is ideally
suited for washing desired areas of the throat such as the tonsils
and may be used for treating inflamed tonsils or tonsillitis by
flushing the tonsil crypts of debris, pus and the tonsillitis
causing bacteria. By using the throat irrigator according to this
invention according to the method explained herebefore, inflamed
tonsils may be treated without the use of surgery or
antibiotics.
In conditions of inflamed throat including pharyngitis the warm
pulsating stream provides a gentle warm massage to the inflamed
throat, thereby bringing quick relief. This again reduces the need
for doctor visits or the need to take antibiotics because fresh
blood carrying the natural body defenses is flushed though the
diseased tissue. In addition, the surface bacteria are removed.
This throat irrigator which delivers a directed pulsating warm
liquid is advantageous also in that it will relieve and reverse a
common painful condition known as post-pharyngeal lymphoid
hyperplasia. In this condition lymphoid tissue similar to tonsil
tissue grows in the back and side of the throat. This disease
responds poorly to antibiotics, medicine, and surgery. On the other
hand, the warm gentle massage delivered by the present throat
irrigator tip is successful in reducing the size and amount of the
lymphoid tissue; and periodic irrigation prevents recurrence of
this tissue. Since the shape of the upper portion of the throat is
substantially semicircular, the pulsating fluid, after impinging on
one of the tonsils as described and illustrated herein, is at least
partially deflected rearwardly or inwardly of the mouth, traverses
the back of the throat laterally, and thence forwardly past the
other tonsil and outwardly of the mouth.
Wide use of the throat irrigation tip should reduce the total
amount of antibiotics being used, thereby reducing the numbers of
bacteria that develop resistance to antibiotics.
