1. Field of the Application
The invention relates generally to breastpumps. More particularly, the present invention relates a system for adhesively supporting a breast shield, as well as related breast pump equipment, on a woman's breast, and a method of using the same.
2. Description of the Related Art
Breastpumps for the purpose of extracting breastmilk from a nursing mother are well-known and generally comprise: a breastshield (also known as a hood) that is typically funnel-shaped and fits over the breast; a pressure source, typically vacuum, connected to the breastshield for generating an intermittent vacuum within the breastshield such that milk is expressed from the breast; and a conduit structure for communicating milk from the breastshield to a receptacle for the expressed milk, as well as for communicating pressure variations (such as the foregoing vacuum) to the breastshield. There are occasions when mothers cannot conveniently plug a breastpump into an external vacuum source or an electrical outlet is not available. In those instances, battery-powered or manual breastpumps may be used to express milk.
Manually-operated breastpumps typically must be operated by two hands: one to hold the breastshield in place and the other to drive the pump (e.g., a piston cylinder). A number of the pumps do provide for one-handed use, but still plainly require the use of a mother's hand(s) to operate or support the pump—such as when double-pumping using a motor-driven pressure source—thus limiting the mother's activities, and in some instances preventing the mother from accomplishing any other task while she is expressing milk.
U.S. Pat. No. 5,514,166 to Silver et al. describes one attempt at breast shield support, such as a garment, for supporting a breastshield of a breast pump upon a woman's breast in a “hands-free” manner. While useful in freeing up the mother's hands for other activity, these and similar “hands-free” arrangements generally require a separate garment, special bra, or other accessories and accoutrements to keep the breastpump assembly in place, especially if also supporting the milk container.
Thus, it would be advantageous to provide a mother with something that could be simply and readily used to permit her to use a breastpump, while also allowing her the free use of her hands to perform other tasks, yet does not require any extra or special garment. It would likewise be useful to provide such a solution that is reusable, or alternatively inexpensive enough to be disposable.
The present invention variously meets these foregoing objectives, and more, by providing a breastshield that may be adhesively secured to a mother's breast for use in a breastpumping system. The adhesive is sufficiently strong so as to independently support the breastshield in position throughout a breastpumping session, including supporting the milk container, thereby enabling the mother to participate in other activities during the pumping session. The adhesive is advantageously of a type that is readily removed from the breast with the breastshield, and most preferably without leaving any significant residue.
In one embodiment, the breastshield is provided with a separate adhesive pad that has a layer of adhesive on one side covered by release paper. The pad is placed on the breastshield, as on the back (outward facing) side. A portion of the pad extends beyond the breastshield, and attaches to the breast, thereby adhering the breastshield in place. Alternatively, a double-sticky pad can be provided, which would have one side adhered to the front (inboard) side of the breastshield, and the other side adhered to the breast.
In another embodiment, a yoke-like device is provided with a center ring from which extend arms ending in adhesive tabs. The center ring releasably fits about the nipple tunnel of the breastshield, with the arms extending outwardly therefrom. The tabs are used to secure the breastshield to the breast (or chest).
In yet another embodiment, a sling-like support strap is provided with adhesive pads at each end. Once the breastshield is placed on the breast, one of the pads is affixed to the breast or chest. The support strap then is directed in a downwardly direction, passed under the nipple tunnel of the breastshield, and then directed in an upwardly direction. The remaining pad is then affixed to the breast or chest, thereby supporting the breastshield assembly and retaining the breastshield in place.
In still another embodiment, a sleeve designed to conform to the outside of the breastshield has a ring of adhesive about its circumference that is to be placed over a breastshield. The sleeve fits over the breastshield and is pressed against the breast for the adhesive to adhere the assembly to the breast.
In a further embodiment, the breastshield is provided with a separate mounting ring having a flange preferably constructed of a soft pliable material positioned along the ring's inner circumference. Adhesive is provided along one side of the ring. With the ring adhered to the mother's breast/chest, the outer perimeter of the breastshield is then slid (wedged) behind the flange, thus retaining the breastshield in place. Alternatively, an interior annular channel can be provided in the ring, within which the perimeter edge of the breastshield is received to mount the breastpump assembly.
While the invention can be used for a single breastpump assembly, in general, all of these embodiments yield a system providing for hands-free simultaneous expression of milk from both breasts. Two breastpump assemblies are connected via a neck strap that is intended to be worn around a mother's neck. Each breastshield is then further provided with a support strap that performs much like a tether having adhesive pads at each end for positioning the shield on the breast. With the breastshields in place, the neck strap is placed about a mother's neck. The tether straps are positioned over the top of the respective nipple tunnels, with the ends of the straps then secured in place below the height of the breastshield on either side, for a secure positioning of the breastpump assemblies.

The present invention is described herein largely with respect to embodiments that use a conventional breastpump assembly. The standard breastpump assembly components are therefore largely unaltered, and need not be adapted to implement this invention. This embraces the utility of the invention, since specialty breastshields or related componentry need not be made or adapted to use the invention. Some embodiments nonetheless are shown with breastshields somewhat adapted for use of the invention, but presenting further useful advantages. Other adaptations can be made with breastshield changes to further enhance the interface and ease of use and reuse, such as in instances discussed herein. For general details, the breastpump assembly comprises: a breastshield that is typically funnel-shaped and fits over the breast; a vacuum source connected to the breastshield for generating an intermittent pressure within the breastshield such that milk is expressed from the breast; and a conduit structure for communicating milk from the breastshield to a receptacle for the expressed milk, as well as for communicating pressure variations (such as a vacuum) to the breastshield. Reference can be made to U.S. Pat. Nos. 5,776,098 and 6,676,631 for general details of a breastpump assembly and its operation.
Referring to
This embodiment further includes a separate adhesive pad 14 in the general shape of an ellipse-like structure. The pad 14 can be made of a non-woven, thin plastic, polyethylene or rubber material, just to name a few possibilities, and has a layer of adhesive 15 on one side, the adhesive being covered by a release paper. The exact nature of the pad 14 is non-limiting, being a stock item in the art. The material is much like the variety that is used with standard adhesive bandages. Referring to
In use, release paper part 17 is removed and the pad 14 is placed over the top portion of the breastshield 10. The adhesive on the lower portion of the pad adheres the pad 14 to the breastshield 10. The breastshield 10 is then positioned on the breast. If the area of the pad 14 covered by release paper part 17 extends beyond the perimeter of the shield, that portion can be pressed lightly so that the adhesive on the lower portion of the pad holds it in position. Thus, the pad 14 positions a portion of the breastshield between the adhesive pad and the breast. With the breastshield 10 in place, release paper part 16 is removed (
a) and (b) depict another embodiment of the present invention. A breastshield 20 is shown in conjunction with an attachment device having a center ring 21 with a number of tabs 22. The embodiment is depicted with three tabs; alternately, a different number of tabs may be used to secure the breastshield to the breast without departing from the scope of the invention.
The center ring 21 fits about the nipple tunnel 24 of the breastshield 20 and the tabs 22 extend radially outwardly from the center ring 21. The center ring 21 may be an integral piece that is slid over the nipple tunnel 24, or alternately may be provided with a separation that allows the ring to fit around the tunnel 24. The ring parts (ends thereof) could attach to each other, for example, or snap fit around the tunnel. The center ring 21 may be made of any number of suitable materials, such as thermoplastic elastomers, other plastics, silicone, and the like, and tabs 22 are preferably constructed of like material as desired. Each tab 22 is provided at its distal end with an adhesive portion 25. Once the breastshield 20 is positioned on the breast, the release paper 26 is removed from each tab 22, and the tabs 22 are adhered to the skin, in a three-point mounting arrangement.
a) and (b) depict yet another embodiment of the present invention. To secure the breastshield 30 to a mother's breast, a support strap 32 is provided with pads 34 at each end. The support strap and pad are preferably constructed of fabric, plastic or any number of other materials ordinarily used to make lightweight straps. Each pad 34 is provided with a layer of adhesive 35 on one side and a release paper 36. Once the breastshield 30 placed on the breast, the release paper 36 from one of the adhesive pads 34 is removed and that pad is affixed to the breast. The support strap 32 then is directed in a downwardly direction, passed under the nipple tunnel 38, and then directed in an upwardly direction. The release paper 36 from the remaining pad 34 is then removed, and the remaining pad 34 is affixed to the breast. The pads need not be positioned in any specific location on the breast or upper torso, other than being located generally above the nipple tunnel of the breastshield so as to form a sling-like support. Note that a cross-over arrangement of the strap ends may be advantageous.

This
It will further be noted that when this and various other embodiments are referred to as being attached to the breast with the adhesive, that attachment may often extend beyond the breast to the adjacent chest region (indeed there may be no adhesive fixation directly to the breast at all in some instances).
In the embodiment of
In use, the release paper 56 is removed from the ring 52, and the ring 52 is positioned around the mother's breast and secured thereto with the adhesive, as shown in
Alternately, the flange 54 may be provided with an annular lip 59 into which the perimeter of the breastshield 50 fits, as shown in
As still another variation on the foregoing, the adhesive ring 52 could be placed (in whole or in part) not on a mounting ring but directly on/around the breast. For example, a ring (or partial ring) of double-sticky tape or the like could be provided. This tape ring is then put in place on the breast/torso, and the release paper on the now-outboard side removed to attach the breastshield. The tape ring could conceivably be left in place, with the release paper re-covering the tape ring between uses.
The embodiment of
a) represents a further embodiment of the present invention that provides a system 80 for hands free simultaneous expression of milk from both breasts. Two breastpump assemblies 82 (similar to that of
Each breastpump assembly 82 has a shield 98, shown best in
In use, the shields 98 are placed on the breast. The neck strap 86 is placed about a mother's neck. The support strap 100 is, in this embodiment, draped over the nipple tunnel 108 of the shield insert 98, and the pads 102 affixed to the breast below the level of the nipple tunnel upon removal of the release paper 106. The pads need not be positioned in any specific location on the breast other than generally being located below the nipple tunnel of the breastshield so as to provide this three-point fixation. The support strap 100 and the adhesive pads 102 keep each shield 98 in the desired place.
The present invention does not require the use of a specific type of adhesive to be used. Rather, the adhesive must be strong enough to support the weight of the breastshield, a collection bottle, and 5 ounces of milk in those versions not using some other component for support (such as in
Adhesives considered suitable, but without being limited thereto, would be of the type used for attachable breast forms, such as on the Trulife Harmony “Connect” product, and the adhesive used on the NuBra “Aphrodite” bra product. Wonderful Breast, Inc. provides a roll-on adhesive product called “It Stays,” and double-sided tapes for garment securement. Avery Dennison Medical's MED 5717P product has a non-sensitizing acrylic pressure-sensitive adhesive including Kraft-paper release liner that may be used. 3M provides a foam tape using an acrylate adhesive, such as Foamtape 9973 and 9772L. Coloplast uses a double-layered adhesive for its ostomy products that should be adaptable to use with the present invention. Chen U.S. Pat. No. 6,780,081 can be looked to for pressure-sensitive adhesive materials in the environment of the invention.
