DESCRIPTION
RESUSCITATION DEVICE AND
METHOD OF USING THE SAME
Technical Field
The present invention is directed toward a resuscitation device and,
more particularly, to such a device which is adapted to be internally secured within
a victim's mouth to facilitate the formation of an air tight seal. The present
invention also relates to a method of using the resuscitation device.
Background Art
When a person stops breathing, air must be forced into his or her
lungs at regular intervals in order to provide the interchange of air necessary for
respiration. While mechanical respirators have been developed for use in
performing respiration, such devices are inconvenient to carry and, in emergency
situations, are not typically available. Accordingly, mouth-to-mouth resuscitation
must be administered in order to restore respiratory function to the victim.
With the rise of communicable diseases such as acquired immune
deficiency syndrome (AIDS), hepatitis A, B and C, herpes simplex, tuberculosis,
and mononucleosis, individuals have been increasingly reluctant to administer
mouth-to-mouth resuscitation since direct contact between the rescuer and the
victim is required. This is particularly true in cases where the victim is unknown to
the rescuer.
In recognition of the foregoing, various non-mechanical, respiration
devices have been disclosed which are designed to reduce the risks associated with
mouth-to-mouth resuscitation. Such known devices typically include a tube which
is adapted to be inserted into the breathing passage of the victim. A common
drawback associated with many of these known devices is that a substantially
airtight seal cannot established over the victim's mouth. This has an adverse
impact on the efficiency of such devices.
Improvements in resuscitation devices were made with the
development of the "donut mask" which includes an inflatable contact rim which,
when filled, becomes resiliently elastic and can therefore adapt itself to cover the
face of a victim and obtain a relatively effective seal. However, such masks
typically do not create an effective seal with (1) victims who have facial hair; (2)
victims with thin faces, and/or (3) victims who do not have any teeth. Further,
existing donut masks are positioned over the victim's mouth and generally must be
repositioned every time the victim's head is moved. Lastly, many donut masks
obstruct the rescuer's view inside the patient's mouth. Accordingly, the rescuer
cannot readily determine if the victim's breathing passage is blocked with, by way
of example, vomit, blood and/or other matter.
Disclosure of the Invention
The present invention is designed to overcome the deficiencies of
the prior art discussed above. It is an object of the invention to provide a device
which is adapted to be partially inserted into a victim's mouth in order to create an
air tight seal with the same.
It is a further object of the invention to provide a resuscitation
device which allows a rescuer to readily determine whether the victim's breathing
passage is obstructed with vomit, blood or other matter.
In accordance with the illustrative embodiments, demonstrating
features and advantages of the present invention, there is provided a resuscitation
device for permitting effective mouth-to-mouth resuscitation on a victim. The
device comprises a central portion with an opening formed therein, a flange
extending from the perimeter of the central portion, and a tubular member
extending outwardly from the central portion. The central portion includes a front
face and a rear face. The tubular member extends outwardly from the front face of
the central portion. The flange is sized to be partially situated between the gum line
and the lips of the victim.
A method of using the resuscitation device is also provided.
Other objects, features and advantages of the invention will be
readily apparent from the following detailed description of a preferred embodiment
thereof taken in conjunction with the drawings.

For the purpose of illustrating the invention, there is shown in the
accompanying drawings one form which is presently preferred; it being understood
that the invention is not intended to be limited to the precise arrangements and
instrumentalities shown.

present invention;
FIG. 2 is a rear planar view of the resuscitation device of the present
invention;
FIG. 3 is a front planar view of the resuscitation device, and
FIG. 4 is a perspective view of the device shown situated within the
mouth of a victim.
Best Mode of Carrying Out Invention
Referring now to the drawings in detail wherein like reference
numerals have been used throughout the various figures to designate like elements,
there is shown in the figures a resuscitation device constructed in accordance with
the principles of the present invention and designated generally as 10.
The resuscitation device 10 allows a rescuer to provide effective
mouth-to-mouth resuscitation to a victim. The device essentially includes a central
portion 12 having an opening 14 formed therein, a flange 16 extending outwardly
from the perimeter 18 of the central portion, and a tubular member 20.
The central portion 12 has a front face 22 and a rear face 24, and
preferably is elliptically shaped as best shown in FIG. 1. In the preferred
embodiment, the central portion is comprised of a translucent, polymeric material.
It is desirable for the central portion 12 to be comprised of a translucent material to
provide the rescuer with a relatively unobstructed view into the mouth of the
victim to determine if the victim's breathing passage is obstructed with blood,
vomit or other matter. The diameter of the opening 14 is preferably from about 2.0
cm to about 4.0 cm.
The flange (or rim) 16 extends from the perimeter 18 of the central
portion 12 and is tapered downwardly from the center thereof. The flange is
designed to be partially situated between the gum line and the lips of the victim so
that an airtight seal can be formed therebetween. (FIG. 4)
The resuscitation device 10 preferably has a length of about 8 cm to
about 12 cm (measured across the center of the device from opposing ends thereof)
and a height of about 3 cm to about 6 cm (measured from top to bottom along the
center of the device). The size of the device 10 will depend on whether it is to be
used on an adult, a child or an infant patient.
Obviously, a larger device will be selected if it is to be used on an
adult rather than on a child or an infant. It follows that a resuscitation device
which is to be used on a child will be larger than a device which is to be used on an
infant. It is important for the rescuer to select the correct size of the device for the
appropriate victim to ensure that an airtight seal will be formed between the gum
line and lips of the victim as more fully described below.
In the preferred embodiment, the dimensions of an adult sized
resuscitation device 10 are as follows: a length of about 12 cm (measured across
the center of the device from opposing ends thereof) and a height of about 5 cm
(measured from top to bottom along the center of the device). As stated above, the
dimensions of a child sized device are slightly smaller than the adult sized device.
Similarly, the dimensions of an infant sized device are slightly smaller than the
child sized device.
A nose clip 26 is secured to the front face 22 of the central
portion 12 by means of a tether line 28 as shown in FIGs. 1 and 3. Specifically, the
tether line 28 has one end 30 secured to the front face 22 of the mask and an
opposite end 32 secured to the nose clip. The nose clip 26 allows the rescuer to
occlude the victim's nose during resuscitation while allowing the rescuer's
hand to remain free to perform other necessary functions The nose clip is
preferably comprised of a plastic material.
In the preferred embodiment, the tubular member 20 is formed
integrally with the central portion 12 of the device and extends outwardly from the
opening 14 therein. In an alternate embodiment, the tubular member may be
separate from the central portion and secured around the opening by means of an
elastomeric adhesive or the like. The diameter of the tubular member 20
corresponds to the diameter of the opening 14 in the central portion 12.
The tubular member 20 includes a portion which extends outwardly
from the front face 22 of the central portion 12 and which terminates in an end 36
as shown in FIGs. 1 and 3. The portion of the tubular member that extends
outwardly from the front face 22 of the central portion 12 is preferably from
about 1.5 to about 3 cm long.
In order to facilitate an understanding of the principles associated
with the present invention, its operation will now be briefly described. The
resuscitation device 10 is inserted into the victim's mouth so that the tubular
member 20 extends outwardly therefrom. As stated above, the particular size of
the device selected will depend on whether an adult, a child or an infant needs to be
resuscitated. The flange 16 is partially situated between the gum line and the lips
of the victim. The nose clip 26 is then positioned to squeeze the victim's nostril's
shut to avoid air from being misdirected. (FIG. 4)
With the device 10 properly in place, the rescuer forces air through
the tubular member 20 and into the lungs of the victim. Alternately, a mechanical
device can be attached to the end 36 of the tubular member in order to force air into
the victim's lungs. Further, a filter can be secured to the end 36 of the tubular
member 20 in order to create a sanitary barrier between the rescuer and the victim
and prevent the transmission of disease.
Since the device of the present invention is designed to be internally
situated in a victim's mouth in the manner set forth above, the absence of teeth of
the victim or the presence of facial hair on the victim will not prevent an airtight
seal from being formed. Further, the device will not be readily dislodged if the
victim's head is repositioned and external pressure is not required to be applied to
the device in order to maintain it in place.
The present invention may be embodied in other specific forms
without departing from the spirit or essential attributes thereof and accordingly
reference should be made to the appended claims rather than to the foregoing
specification as indicating the scope of the invention.
