BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to head supports, and more
particularly, to a head support apparatus especially adapted to support a
patient's head when the patient is lying in a prone position.
2. Description of the Prior Art
Head supports are well known in the art. For example, the following U.S.
Pat. Nos. disclose head supports: 4,345,347 of Kantor; 4,821,736 of
Watson; 4,918,774 of Popitz; 4,928,711 of Williams; and Des. 244,336 of
Stein. Yet, none of the patents cited disclose a head support apparatus
that is suitable for supporting a patient's head when the patient is lying
in a prone position, on the patient's stomach, such as during surgery or
during a medical examination.
When a patient is in a prone position during surgery, the patient's head is
most often turned to either the right or left; and the patient's head
rests on its left side or right side, respectively. With the head turned
in this way, the windpipe may be somewhat constricted. Also, with the head
turned in this way, certain neck muscles may be overly stressed resulting
in aching neck muscles for some period of time after surgery or the
examination is over. In this respect, it would be desirable if a head
support were provided in which the head would not be turned and the
windpipe would not be constricted when the patient is lying in a prone
position. Also, it would be desirable if a head support were provided in
which the head is not turned and excessive stress is not applied to neck
muscles when the patient is lying in a prone position.
A conventional pillow may also be used to support a head. When a patient is
in a supine position, lying on the patient's back, and the patient's face
oriented straight up, there is no problem with the patient being
suffocated by the pillow. However, when the patient is in a prone
position, if a patient's face would be placed face down on a pillow, then
the pillow may suffocate the patient. With a pillow, no clearance or open
space is provided to permit the patient to breath through the mouth or
nose when the patient is in a prone position, without turning the
patient's head to the right or left as described above. Thus, it would be
desirable if a head support apparatus were provided which supported a
patient's face in a prone position with a provision for permitting the
patient to breath through the mouth and/or nose.
The head supports mentioned above all use solid materials to provide the
support needed. The solid materials may be of a number of types such as: a
particulate material, such as feathers in a pillow; a foam material such
as foam rubber; or a canvas material, among others. Pillows containing air
are also known. However, such air-containing pillows are not known to be
suitable for supporting a patient in a prone position during surgery or
medical examination without turning the patient's head to the left or
right side.
Thus, while the foregoing body of prior art indicates that it is well known
to use head rests generally, the provision of a simple and cost effective
device for supporting a patient's head while the patient is in a prone
position is not contemplated. Also, the prior art does not provide a head
support with which the head is not turned, and the windpipe is not
constricted. Nor does prior art provide a head support in which the head
is not turned, and excessive stress is not applied to neck muscles when
the patient is lying in a prone position. In addition, the prior art does
not provide a head support which supports a patient's face in a prone
position and also permits the patient to breath through the mouth and/or
nose. Also, the prior art does not provide air-cushioning pillows which
are suitable for supporting a patient in a prone position during surgery
or medical examination. The foregoing disadvantages are overcome by the
unique head support apparatus of the present invention as will be made
apparent from the following description thereof. Other advantages of the
present invention over the prior art also will be rendered evident.
SUMMARY OF THE INVENTION
To achieve the foregoing and other advantages, the present invention,
briefly described, provides a new and improved head support apparatus
which includes a base member and a nonrigid chin rest member, a nonrigid
forehead rest member, and a number of peripheral guide members supported
by the base member. The chin rest member and the forehead rest member
project from the base member a first vertical distance which is longer
than a nose of the person when the chin of the person is resting on the
chin rest member and the forehead of the person is resting on the forehead
rest member. The forehead rest member is spaced from the chin rest member,
on the base member, by a horizontal distance which is greater than a
height of the nose of the person. The peripheral guide members project
from the base member a vertical distance which is longer than the first
vertical distance, and peripheral guide members are spaced from one
another on the base member by a horizontal distance which is sufficient to
permit the person's head to be restrained between the peripheral guide
members when the forehead of the person is resting on the forehead rest
member.
The base member includes air channels for supplying air to the chin rest
member and the forehead rest member. The chin rest member and the forehead
rest member also include glass microspheres. A slidable carriage may
support the peripheral guide members; and a groove in the base member then
supports the slidable carriage. Adjustment screws are provided for locking
the slidable carriage in a selected position with respect to groove. In
addition, an aroma diffuser assembly supported may be present in the base
member.
The above brief description sets forth rather broadly the more important
features of the present invention in order that the detailed description
thereof that follows may be better understood, and in order that the
present contributions to the art may be better appreciated. There are, of
course, additional features of the invention that will be described
hereinafter and which will be for the subject matter of the claims
appended hereto.
In this respect, before explaining at least three preferred embodiments of
the invention in detail, it is understood that the invention is not
limited in its application to the details of the construction and to the
arrangements of the components set forth in the following description or

DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference to the drawings, a new and improved head support apparatus
embodying the principles and concepts of the present invention will be
described.
Turning initially to FIGS. 1-4, there is shown a first exemplary embodiment
of the head support apparatus of the invention generally designated by
reference numeral 10. In its preferred form, head support apparatus 10 is
for a person's head 11 and includes a base member 12, a nonrigid chin rest
member 14 supported by the base member 12 and projecting from the base
member 12 a first vertical distance 16 which is longer than a nose 13 of
the person when a chin 15 of the person is resting on the chin rest member
14.
The head support apparatus 10 of the invention also includes a nonrigid
forehead rest member 18 supported by the base member 12 and projecting
from the base member 12 a second vertical distance 20 which is longer than
the nose 13 of the person when a forehead 17 of the person is resting on
the forehead rest member 18, and wherein the forehead rest member 18 is
spaced from the chin rest member 14, on the base member 12 by a first
horizontal distance 22 which is greater than a height 19 of the nose of
the person.
Two peripheral guide members 24 are supported by the base member 12 and
project from the base member 12 a third vertical distance 26 which is
longer than the first and second vertical distances 16 and 20. The two
peripheral guide members 24 are spaced from one another on the base member
12 by a second horizontal distance 28 which is sufficient to permit the
person's head 11 to be restrained between the peripheral guide members 24
when the forehead 17 of the person is resting on the forehead rest member
18.
A third peripheral guide member 30 is supported by the base member 12 and
projects from the base member 12 by the third vertical distance 26 which
is longer than the first and second vertical distances 16 and 20. The
third peripheral guide member 30 is spaced from the forehead rest member
18 by a third horizontal distance 32 which is sufficient to permit a top
21 of the person's head to be restrained by the third peripheral guide
member 30 when the forehead 17 of the person is resting on the forehead
rest member 18.
The base member 12 includes a first air channel 34 for supplying air to the
chin rest member 14 and a second air channel 36 for supplying air to the
forehead rest member 18. The first air channel 34 and the second air
channel 36 diverge from a common supply tube 38. The common supply tube 38
includes a one-way valve 40. A conventional air pump (not shown) is used
to supply pressurized air to the air channels 34 and 36.
The chin rest member 14 and the forehead rest member 18 include glass
microspheres 23. As shown in FIG. 3, the chin rest member 14 also includes
a rubber bladder 25 which is contained within an outer fabric covering 27.
A fitting 29 is present to connect the interior space of the chin rest
member 14 to the first air channel 34.
In use, when a person's head 11 is positioned on the head support apparatus
10 of the invention, such as during surgery, the person's chin and
forehead are gently cushioned by the chin rest member 14 and the forehead
rest member 18, respectively. The combination of air pressure and
microspheres provides a particularly effective, gentle cushioning action.
At the same time, the person's head 11 is retained in a prone position
without constricting the windpipe. Moreover, a clearance is provided for
the person's nose 13 so that breathing is unimpeded.
Turning to FIGS. 5-6, a second embodiment of the head support apparatus 10
of the invention is shown. Reference numerals are shown that correspond to
like reference numerals that designate like elements shown in the other
figures. In addition, in FIGS. 5-6, an adjusting assembly is provided for
adjusting the third horizontal distance 32. The adjusting assembly
includes a slidable carriage 44 which supports the peripheral guide
members 24 and 30. A groove 46 in the base member 12 supports the slidable
carriage 44. Adjustment screws 48 are provided for locking the slidable
carriage 44 in a selected position with respect to groove 46.
Turning to FIGS. 7-8, a third embodiment of the head support apparatus 10
of the invention is shown. Reference numerals are shown that correspond to
like reference numerals that designate like elements shown in the other
figures. In addition, in FIGS. 7-8, an aroma diffuser assembly 50 is
provided and is supported by the base member 12. The aroma diffuser
assembly 50 includes a well 52 located in the base member 12. A lid 54
includes a plurality of openings 56, and the lid 54 covers the well 52. A
quantity of aroma-bearing material 58 is contained in the well 52.
It is apparent from the above that the present invention accomplishes all
of the objects set forth by providing a new and improved head support
apparatus that is low in cost, relatively simple in design and operation,
and which may advantageously be used for supporting a patient's head when
the patient is lying in a prone position, such as during surgery or during
a medical examination.
With respect to the above description, it should be realized that the
optimum dimensional relationships for the parts of the invention, to
include variations in size, form function and manner of operation,
assembly and use, are deemed readily apparent and obvious to those skilled
in the art, and therefore, all relationships equivalent to those
illustrated in the drawings and described in the specification are
intended to be encompassed only by the scope of appended claims.
While the present invention has been shown in the drawings and fully
described above with particularity and detail in connection with what is
presently deemed to be the most practical and preferred embodiments of the
invention, it will be apparent to those of ordinary skill in the art that
many modifications thereof may be made without departing from the
principles and concepts set forth herein. Hence, the proper scope of the
present invention should be determined only by the broadest interpretation
of the appended claims so as to encompass all such modifications and
equivalents.
