CUSTOM-MADE ARTIFICIAL NIPPLE
An artificial nipple is formed of an elastomeric polymer by use of 3D printing after imaging of a mother's breast in an active state of lactation. The artificial nipple used as an attachment to a baby bottle or as the nipple component of a pacifier. Use of an artificial nipple formed in this manner mitigates a problem with nipple confusion, as may otherwise manifest in newborn offspring.
This application s claims benefit of priority to U.S. provisional patent Application Nos. 62/330,367 and 62/330,634 filed May 2, 2016, each of which are incorporated by reference as though fully replicated herein.
BACKGROUND Field of the InventionThe present disclosure pertains to the field of three dimensional printing (3D printing) of anatomy. More particularly, 3D printing is used to replicate a nursing mother's nipple.
Description of the Related ArtBreastfeeding is associated with many advantages for both mother and baby. Some studies suggest an association between breastfeeding and; (1) lower risk of asthma or allergies; (2) fewer ear infections, respiratory illnesses and bouts of diarrhea; (3) higher IQ scores for the baby later in childhood; and (4) improved weight for both mother and baby. Many breastfed infants are also fed using conventional baby bottles. Nipple confusion sometimes arises where a bottle-fed baby “forgets” how to nurse on mother's nipple. This happens because breastfeeding requires far more vigorous mouth and tongue motions and greater muscle coordination than does bottle-feeding. Thus, a newborn who is exposed to conventional bottle nipples or even conventional pacifiers can cease to nurse properly. The art provides no known solution to this problem, other than to let the baby rediscover how to nurse.
3D printing, which is sometimes called additive manufacturing, is a well-known process for producing three dimensional objects. Conventionally, robotic processing utilizes inkjet-like printer heads to deposit successive layers of material into the shape of a three dimensional article. Deposition methods, among others, include such extrusion technologies as fused deposition modeling and, fused filament fabrication of thermoplastics. See, for example, Chee Kai Chua; Kah Fai Leong; Chu Sing Lim (2003). Rapid Prototyping. World Scientific. p. 124. ISBN 978-981-238-117-0. Powder bed deposition technologies include selective heat sintering and selective laser of thermoplastic powder. Powder bed and inkjet head printing may be used to deposit most metal alloys, plaster and powdered polymers. See for example, U.S. Pat. No. 4,247,508 to Housholder for “Molding Process” issued to Hiemenz; and “Rapid prototypes move to metal components, EE Times, Mar. 9, 2007. 3D printing processes may be utilized to make 3D articles utilizing polymers, metals, and ceramics. By way of example, U.S. Pat. No. 7,569,273 issued to Bredt et al., describes the use of powder deposition technology to deposit thermoplastic silicone materials.
3D articles may be printed utilizing a computer-aided design package, a scanner, an ordinary camera, or a 3D specific camera to feed data to photogrammetry software. Commercially available software for this purpose includes, for example, ContextCapture, Pix4Dmapper, Photoscan, 123D Catch, Bundler toolkit, PIXDIM, and Photosketch. 3D Printing has been utilized to make human prosthetic devices. For example, U.S. Pat. No. 5,370,692 to Fink et al. describes the rapid manufacture of bone prosthesis by use of medical computer aided imaging to make a replica of original bone that is deposited using laser-bonded layers of ceramic particles. U.S. Pat. No. 8,454,362 describes the use of a 3D camera to capture data that may be used in making a dental prosthesis, such as a crown.
U.S. Pat. No. 9,044,380 to Sabree et al. describes a process of impression-molding a mother's breast to make a mold from which may be cast either a nipple for a baby bottle or a pacifier. This is problematic in the sense that, practically speaking, the time required for the impression-forming process precludes making a mold of the breast in an active state of lactation, as described below. Moreover, the resins utilized in casting custom nipples from this impression are of questionable safety when used in combination with baby products. Lastly, the impression-forming process physically distorts the nipple area of the breast, which defeats the purpose of forming a custom nipple that closely resembles that of a mother's breast.
Some attempts have been made to make artificial nipples by use of 3D printing, but without good success. WO2017/019401 to Dretzaka-Kaye et al describes a vacuum chamber that retains a breast in position for a laser scanning operation that creates a digital imaging file. The nipple region of the breast may be reproduced as an artificial nipple by use of 3D printing, stereo lithography or molding processes. Here the vacuum problematically distorts the mother's nipple to a non-natural state other than that which would be presented to an infant. Similarly, WO2016/154681 to Mobbs shows imaging of a breast that may be reproduced by use of 3D printing; however, the breast is not placed in an active state of lactation as would normally presented to an infant.
SUMMARYThe presently disclosed instrumentalities advance the art and overcome the problems outlined above by mitigating the problem of nipple confusion. This is done by the use of 3D printing technology to provide an artificial nipple or pacifier that closely resembles the naturally occurring nipple of a child's mother or wet nurse in a state of active lactation. As used herein a “child” may be a human child or a non-human mammalian child.
In one aspect, an elastomeric artificial nipple structure is formed for use as a substitute nipple or pacifier for a nursing child. The artificial nipple structure is custom-made to provide a nipple portion that closely resembles an actual nipple in an active state of lactation that is normally presented to the child when nursing. Generally speaking, the nipple portion described above reproduces the areola and nipple region of a breast and may also transition into an area of the breast posterior of the areola. The actual nipple may be, for example a human nipple. As used herein, the term “closely resembles” means that the reproduced region of areola and/or nipple of a mother's breast is exactly reproduced within a dimensional tolerance that externally deviates less than about 4 or 5% from the original in terms of external length, height and width, or another suitable tolerance that is achievable by 3D printing processes. This variance is preferably less than 3% and more preferably less than 1%. The reproduced region of areola and nipple may be provided with surface texturing features corresponding to those of the actual breast, or else artificial texturing may be provided within the range of dimensional tolerance as an aid to simulate such texture and facilitate suckling.
In another aspect, the artificial nipple may be formed as a component of a baby bottle or a pacifier.
In one aspect, the artificial nipple structure may be cast from a mold to which a synthetic resin may be added to form elastomeric artificial nipples.
A process for making the elastomeric artificial nipple includes converting a breast into an active state of lactation and imaging the breast to obtain 3D image data including a nipple component of the breast. The 3D image data is then processed to provide a print data file, which is submitted to a 3D printer for printing of the artificial nipple structure based upon the print data file to provide an artificial nipple structure with a component that closely resembles a nipple region of the breast.
The female breast is ordinarily divided into 15-25 lobes that are separated by connective and adipose tissue. These lobes radiate out from the nipple and are subdivided into lobules. Each lobe drains into a lactiferous duct and each duct has a dilation called a lactiferous sinus behind the nipple for milk storage. As is well known, the ducts branch and grow when activated by estrogen and progesterone stimulation during pregnancy. These stimulated glandular units form alveoli which are secretory units lined by simple cuboidal epithelium, surrounded by a basement membrane and wrapped in myoepithelial cells which surround the entire alveolus. The developing alveoli replace much of the adipose tissue.
As shown in
For embodiments utilizing only one camera, a preferred aspect is to use a 3D scanning technology, such as Microsoft's MobileFusion™ application, which turns an iPhone® into a 3D scanner. This is a class of device that obtains a plurality of pictures from a single imager and is able to use depth of scale in rendering a 3D image that is readily convertible into print image data 308 for use in 3D printing applications.

By way of example,
The artificial nipple structure 404 is alternatively a pacifier 700 closely resembling the actual nipple structure of a mother or wet-nurse. This is shown, for example, in
The grip ring 714 may be integrally formed with the cylindrical base 712 in a single printing operation. Alternatively, the grip ring 712 may be formed with barbs, such as barb 722 at opposed ends, the barbs being insertable through an orifice 724 in the cylindrical base 712 communicating with the hollow interior 716 such that the barb 722 expands in the interior 716 to preclude removal of the barb from the orifice.
An internal structure 910 is formed integral to the second part 904, fitting within the recess formed by margins 908. The internal structure 910 has complementary dimensions with respect to the margins 908, such that a space 912 is provided therebetween. As shown in
The liquid polymer 916 is formulated to cure, for example, into a PVC plastic, latex or silicone based material, and is preferably silicone or a copolymer of silicone in a variety that has regulatory approval for use in the nipples of baby bottles or pacifiers as the case may be. The material may be, for example, a medical grade silicone. The material is preferably free of bisphenol-A (BPA) and nitrosamines.

Although a human nipple is depicted in the drawings, it will be appreciated that the instrumentalities described herein are not limited to human nipples and may be extended to other mammalian nipples, such as those of other primates, livestock, or mammals constituting endangered species.
Those of ordinary skill in the art will understand that the foregoing discussion teaches by way of example and not be limitation. Accordingly, what is shown and described may be subjected to insubstantial change without departing from the scope and spirit of invention. The inventors hereby state their intention to rely upon the Doctrine of Equivalents, if needed, in protecting their full rights in the invention.
