APPARATUS AND METHOD FOR
CONTROLLING EIUMAN LACTATION
S FIELD OF THE INVENTION
The present invention relates to an appalallls and method for controlling
lactation in human females.
BACKGROUND OF THE INVENTION
In recent years, breast feeding of newborn babies has seen a re~ulgence in
popularity. Breast feeding is becoming more popular for a variety of reasons relative to
both baby and mother. These advantages include increased protection of the infant from
illness through the development of protective antibodies, decreased risk of developing
childhood cancers, avoiding potential allergies to commercial infant form~ c, and
enhanced jaw, teeth, and speech development, among others. Furthermore, it has been
suggested that nursing mothers have a lower risk of developing breast cancer. Breast
feeding has also been suggested to improve the emotional bond between mother and child.
Although breast feeding is enjoying renewed use, it is not without
disadvantages. The outpouring of milk is known as the "let-down" or "milk-ejection"
reflex. A let-down can occur several times during a feeding. It is well known that the
milk-ejection reflex can be triggered at inapplopliate times by various stimuli. A baby's
crying, for example, may cause let-down in a nursing mother. This can result in let-down
at very inopportune times.
This inapplopl;ate let-down can be particularly 35 problematic for working
mothers who are nursing. Solutions designed to alleviate problems associated with
inappropl;ate let-down include absorbent breast pads or breast shields that operate,
essentially, as a well or reservoir to collect leaking milk. These solutions aredisadvantageous because of the limited capacity of both types of devices as well as the
likelihood that milk will leak into clothing despite their use.
It is also known that nursing mothers can apply direct ples~u~e to the
nipples with the heels of their hands or forearms to temporarily halt leakage. However,
this type of solution likewise presents obvious disadvantages for the nursing mother who is

working or otherwise in public. Therefore, there continues to be a need for apparatus that
can effectively conkol inopportune lactation in nursing mothers.
SUMMARY OF THE INVENTION
This invention relates to an al)pa~dlus and method for controlling human
lactation. The al~paldlus compri~es a support having an outer surface and an inner surface
that is shaped to conform subst~nti~lly to a human female breast. The inner surface has a
protrusion which extends away from the support and is positioned to align substantially
with and contact a nipple of a human female breast when the ~pal~lus is placed over the
breast. In this way, the prol~ ion substantially prevents the breast from lactating.
The a~alalus can be used alone or include a brassiere which the support is
either placed into or 30 integrated with (e.g., sewn into). The brassiere can be either a
conventional or nursing brassiere.
The present invention also provides a method for controlling human
lactation which utilizes the present apparatus. The method includes the steps of placing
the apparatus over the breast and applying pressure on the apparatus sufficient to prevent
lactation.
The apparatus and method of the present invention provide a convenient and
effective way to prevent inopportune milk leakage in the nursing mother. The apparatus
can be inexpensively constructed in a variety of shapes from a variety of materials.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is an exploded, perspective view of one embodiment of the a~paldlus
of the present invention and an absorbent breast pad. Apparatus 1 includes support 2
having an inner surface 3 and an outer surface 5. Inner surface 3 has a protrusion 7 which
extends away from support 2. Referring to FIG. 7, which is a cross-sectional side view of
one embodiment of the present appaldlus, including a brassiere, placed over a human
breast, protrusion 7 is positioned to align substantially with and contact nipple N of human
female breast B. Protrusion 7 operates to depress nipple N, whereby breast B is prevented
from lactating.
Support 2 is shaped to conform substantially to a human female breast.
Support 2 can, for example, be substantially circular with a concave/convex shape covering
a relatively small area of breast B as shown in FIG. 7. Support 2 can also take a variety
of other forms, substantially conforming to larger or smaller areas of breast B. Preferably,
support 2 is constructed in a substantially circular, concave/convex form and having a
radius from about 3 to 5 inches for m~xhllulll comfort and to allow use of the appalalus
on breasts of various sizes. Most preferably, support 2 is shaped such that suc;ion is
created between breast B and appaldlus 1 after al~palalus 1 is placed over breast B. The
suction helps to m~int~in the alignment of app~alus 1 with nipple N.
Support 2 can be made from a variety of flexible m~teri~l~ including
moldable plastic or rubber. Preferably, the support is made from a moldable, flexible
plastic material to allow m;-xi",l-", comfort and ease of manufacture. With reference to
FIGS. 4 and 6, perspective views of the inner and outer sllrf~ces, respectivèly, of
support 2, support 2 can be provided with holes 4 to allow air circulation around the
nipple and areolar region of breast B to prevent local irritation which commonly occurs in
nursing mothers.

Protrusion 7 can be produced separately and then attached to inner surface 3
or, preferably, integrated with inner surface 3. This preferred embodiment is shown by
FIG. 5, a cross-sectional side view of FIG. 4 taken along line 5-5. Protrusion 7 can be
integrated with inner surface 3 by molding protrusion 7 and support 2 together from the
same material. Protrusion 7 can be made from a variety of materials, as long as the
material is sufficiently rigid to depress nipple N when nipple N is contacted by protrusion
7. Exemplary materials for forming protrusion 7 include any of the rigid plastics
10 known in the art or sufficiently rigidized rubber.
Protrusion 7 can be any shape, so long as it is capable of depressing nipple
N when apparatus 1 is brought into contact with breast B and, in turn, pl~v~llL~ug lactation.
For example, protrusion 7, can be a flattened, planar surface formed in the center of the
inner surface 3 of support 2, as shown by FIG. 8, a cross-sectional side view of an
alternative embodiment of the inner surface of the support and protrusion of the present
invention. Protrusion 7 is preferably cylindrical, having a size approxim~ting a human
female nipple, as shown in FIG. 7. Most preferably, as illustrated by FIGS. 7 and 9,
nipple-contacting surface 8 of protrusion 7 is concave to make the appaldlus more
comfortable for the wearer and aid in keeping apparatus 1 in place.
Preferably, absorbent pad 9 is placed over inner surface 3 to absorb any
small amount of leakage resulting, for example, from mi~lignment of protrusion 7 and
nipple N. This embodiment is illustrated by FIGS. 1 and 7.
As shown by FIG. 7, the above-described appaldLus can be used by placing
it over breast B and applying pressure to the a~aldlus sufficient to depress and, in turn,
prevent milk release by nipple N of breast B. The amount of pressure need not be great
and can normally be produced by the force provided when appalalus 1 further comprises
brassiere 11. Support 2 can be placed inside the cup of brassiere 11 which is then put on
by the lactating woman, as illustrated by FIG. 7. Support 2 can either be manll~lly placed
into or actually integrated with (e.g., sewn into) the cup of the brassiere. Brassiere 11 can
be a conventional or nursing brassiere commonly worn by nursing mothers.
Although the invention has been described in detail, for the purpose of
illustration, it is understood 10 that such detail is for that purpose and variations can be
made therein by those skilled in the art without departing from the spirit and scope of the
invention which is defined by the following claims.
