## Background
TECHNICAL FIELD
This disclosure relates generally to breast pumps. More particularly, the disclosure made herein relates to a human breast pump shield that can be easy to use, comfortable to use, and can be formed as a disposable article for purposes of convenience, sanitation, and/or other reasons.
BACKGROUND
Unless otherwise indicated herein, the details in this section are not prior art to the claims in this application and are not admitted to be prior art by inclusion in this section.
Until the middle of the twentieth century, almost all children were breastfed by their mothers (or a substitute such as a wet nurse). From around the 1940's through the 1990's, the popularity and prevalence of breastfeeding decreased in the United States. In the late part of the twentieth century and over the past ten to fifteen years, breastfeeding has experienced somewhat of a revival in the United States, with medical experts encouraging mothers to breastfeed children based upon a large body of scientific evidence that breastfeeding encourages healthy growth and development of children.
In modern American society, however, many mothers work outside the home or are busy with various activities that often require them to leave their homes. For many mothers, this time away from the home can be disruptive to breastfeeding schedules. Some mothers employ breast pumps to pump or express breast milk at home, at the office, or elsewhere.
Because breast milk is consumed primarily by young children, first and foremost infants of zero to six months of age and secondarily children up to about two to four years of age, some experts encourage sterilization and frequent cleaning of breast pump components. When away from the home, mothers may experience difficulty in finding a suitable place and/or equipment to thoroughly clean the breast pump components. As such, breast pumping outside the home can be difficult for mothers.
Furthermore, some women experience pain during or after breast pumping. In particular, some women experience pain as the nipples enlarge during pumping and/or from rubbing that can occur during use of a breast pump. Various approaches are used in an attempt to reduce this pain. For example, some mothers use a low setting for a breast pump at the beginning of pumping and later, after the nipple has extended and/or enlarged, the suction and/or speed of the breast pump can be increased without causing pain to the mother.
Because some breast pumps do not have variable settings, and because many mothers want to complete breast pumping as quickly as possible when away from the home, some mothers are unable to address the pain that may occur during pumping. Because of this, some mothers are discouraged from breastfeeding their children or may cease breastfeeding at the earliest opportunity.
SUMMARY
Concepts and technologies are disclosed herein for a breast pump shield. As used herein, a “breast” is used to refer only to a breast of a human female and specifically excludes breasts of other living organisms. In some embodiments, a breast pump shield can be formed from a plastic or other material. The breast pump shield can include a body portion and one or more covers. The cover can include multiple layers. According to various embodiments, the cover includes three layers, a lubricant layer, a support layer, and a wiping layer.

The following detailed description is directed to a breast pump shield. In some embodiments a breast pump shield can be formed from a plastic or other material. The breast pump shield can include a body portion and one or more covers. At least one of the one or more covers can include multiple layers. According to various embodiments, at least one of the covers includes three layers, namely a lubricant layer, a support layer, and a wiping layer. A layer of lubricant (“lubricant layer”) also can be located within the body portion of the breast pump shield.
The lubricant layer can be included to reduce irritation associated with using the breast pump shield by lubricating surfaces that come into contact with the breasts of the user and/or portions of the breasts of the user. The lubricant can be formulated in a manner that prevents thinning and/or degradation of the lubricant in high heat environments. Furthermore, the cover can include a lubricant layer so that a user need not apply lubricant to the breasts and/or the breast pump shield prior to use, or so that the user can have extra lubricant if needed or desired. In some embodiments, the lubricant layer is included as a packet of lubricant attached to the cover, wherein a user can squeeze the cover after removing the cover from the breast pump shield, thereby ejecting the lubricant from the lubricant layer for placement on the breast, areola, nipple, shield, or other structure or body part.
The support layer can be provided to support the adhesive layer and the wiping layer, as well as to provide a hermetic seal for the breast pump shield. By providing a hermetic seal for the breast pump shield, the cover can ensure that the breast pump shield remains sterile, as well as preventing leakage of, oxidation of, and/or degradation of the lubricant layer located within the body portion. The wiping layer can be included to provide a wipe or cleaner for the user. The wiping layer can be removed from the other layers, in some embodiments, and can be used to clean up before, during, or after pumping.
According to some embodiments, the breast pump shield and/or components thereof can be formed from a rigid material such as an epoxy resin or other resins, plastics, thermoplastics, acrylics, rubber, synthetic rubber, other polymers or copolymers, combinations thereof, or the like. In some other embodiments, the breast pump shield and/or components thereof can be formed from semi-rigid and/or soft materials such as rubber, plastic films, latex, or the like. The soft material can be located within a frame or other support structures to provide rigidity for the breast pump shield. These and other embodiments of the concepts and technologies described herein will be illustrated and described herein. These and other aspects of the concepts and technologies described herein will be described herein in further detail.
In the following detailed description, references are made to the accompanying drawings that form a part hereof, and in which are shown by way of illustration specific embodiments or examples. It must be understood that the disclosed embodiments are merely illustrative of the concepts and technologies disclosed herein. The concepts and technologies disclosed herein may be embodied in various and alternative forms, and/or in various combinations of the embodiments disclosed herein. The word “illustrative,” as used in the specification, is used expansively to refer to embodiments that serve as an illustration, specimen, model or pattern.
Additionally, it should be understood that the drawings are not necessarily to scale, and that some features may be exaggerated or minimized to show details of particular components. In other instances, well-known components, systems, materials or methods have not been described in detail in order to avoid obscuring the present disclosure. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure. Referring now to the drawings, in which like numerals represent like elements throughout the several figures, aspects of breast pump shields will be presented.
Referring first to FIG. 1, aspects of a breast pump shield 100 according to various embodiments of the concepts and technologies described herein will be described in detail. In particular, FIG. 1 illustrates one illustrative embodiment of a breast pump shield 100. It should be understood that the illustrated and described illustrative embodiment of the breast pump shield 100 shown in FIG. 1 is one illustrative embodiment of the concepts and technologies described herein, and therefore should not be construed as being limiting in any way of the concepts and technologies described herein.
In some embodiments, as shown in FIG. 1, a breast pump shield 100 can include a breast pump shield main body portion (“body portion”) 102 and a cover 104. The body portion 102 can be configured to engage a breast during lactation. The body portion 102 also can be configured to support other components of the breast pump shield 100. As will be illustrated and described in more detail below, the body portion 102 can have various configurations and/or features. As such, the illustrated and described example embodiment shown in FIG. 1 is merely illustrative of the concepts and technologies described herein and should not be construed as being limiting in any way.
The body portion 102 can include various components. In some embodiments, the body portion 102 can include a breast engagement portion 106. The breast engagement portion 106 can be configured to receive and/or engage an outer surface of a breast of a user. The breast engagement portion 106 also can be configured to center a nipple of the breast within the breast engagement portion 106 during lactation/suction and/or to encourage the nipple of the breast to enter a suction and/or stimulation chamber, as will be explained in more detail below.
According to various embodiments, a breast or a portion thereof can be inserted into the breast engagement portion 106 via an open end 108. The open end 108 can be defined, in some embodiments, by a ring 110 of material located at the open end 108. The ring 110 can engage the breast or chest of the user and the breast or areola of the user can be engaged within the breast engagement portion 106, or a portion thereof. The nipple of the breast can pass through the breast engagement portion 106 and into a stimulation and/or suction chamber or region. In the illustrated embodiment, the stimulation chamber or region is provided by a throat portion 112 of the body portion 102. It should be understood that this example is illustrative and therefore should not be construed as being limiting in any way.
The throat portion 112 can be configured to accommodate and/or engage the nipple during lactation. In various embodiments, the throat portion 112 can be configured as a cylindrical passageway. The throat portion 112 can be tapered, in some embodiments, though this is not necessarily the case. During pumping, the nipple can extend to or even into the throat portion 112.
According to various embodiments, the extension of the nipple into, through, or within the throat portion 112 can occur repeatedly with the application of suction to the throat portion. The movement and/or extension of the nipple within the throat portion 102 can encourage and/or stimulate milk flow, as generally is understood. The body portion 102 also can include a suction chamber, structure, or region (“suction chamber”) 114. Air pressure within the suction chamber 114 can be controlled and/or regulated by a breast pump (not visible in FIG. 1), which can be connected to the suction chamber 114 via a hose, connector, or other structure. The hose, connector, or other structure can be connected to or inserted into the suction chamber 114 via an inlet 116. Thus, the breast pump or other device can control air pressure within the suction chamber 114, the throat portion 112, and/or the breast engagement portion 106 via connection through the inlet 116. It should be understood that this example is illustrative and therefore should not be construed as being limiting in any way.
According to various embodiments, the body portion 102 and/or one or more portions thereof can include a lubricant layer (not visible in FIG. 1). In the illustrated embodiment, at least portions of the breast engagement portion 106 and the throat portion 112 include the lubricant layer. In some embodiments, the suction chamber 114, the inlet 116, other portions of the breast pump shield 100 and/or portions thereof can include the lubricant layer. The lubricant layer will be illustrated and described in more detail below, particularly with reference to FIGS. 3-4B. Additionally, the cover 104 will be illustrated and described in more detail below.
Components of the breast pump shield 100 can be formed from various materials. According to various embodiments, the body portion 102 of the breast pump shield 100 and/or components of the body portion 102 such as the breast engagement portion 106, the ring 110, the throat portion 112, and/or the suction chamber 114 can be formed from one or more plastics, one or more thermoplastics, one or more acrylics, one or more resins, one or more polymers or copolymers, other (non-plastic and non-polymer) materials, and/or combinations thereof. According to some embodiments, the body portion 102 of the breast pump shield 100 can be formed using various manufacturing processes such as injection molding processes, three dimensional printing processes, machining processes, forging processes, combinations thereof, or the like. Because other materials and/or processes can be used to form the body portion 102 and/or other components of the breast pump shield 100, it should be understood that these examples are illustrative and therefore should not be construed as being limiting in any way.
In some embodiments, as can be seen in FIG. 1, the cover 104 can include a finger grip, tab, protrusion, or other structure (“tab”) 118. The tab 118 can be used to provide a grip for a user to grasp the cover 104. Using the tab 118, the user can detach the cover 104 from the breast pump shield 100. It can be appreciated that in various embodiments, the cover 104 can be attached to the breast pump shield 100 using an adhesive. Thus, the cover 104 can be peeled away from the breast pump shield 100, in some embodiments, as generally is understood. Because the tab 118 can be optional and/or can be replaced by additional and/or alternative structures or devices, the tab 118 is not shown in the other FIGURES. It should be understood that the tab 118 or other structures or devices can be included in some, all, or none of the illustrated embodiments, and as such, the illustrated embodiments that omit the tab 118 are merely illustrative and should not be construed as being limiting in any way.
In some embodiments, the cover 104 can be configured such that the cover can enwrap the entire breast pump shield 100 or a component thereof. For example, in some embodiments, the cover 104 can enwrap the entire breast pump shield 100, the entire body portion 102, the entire throat portion 112, and/or other components of the breast pump shield 100. In some embodiments, the components of the breast pump shield 100 can be enwrapped or enclosed by the cover 104 and/or multiple covers 104, so a user can unwrap the components and assembly the sterile and lubricated components together. In some other embodiments, the entire breast pump shield 100 can be unwrapped, and then can be used as a sterile and lubricated breast pump shield. Thus, the embodiments shown in the FIGURES, wherein the cover 104 covers only a portion of the breast pump shield 100 should be understood as being illustrative of some contemplated embodiments and should not be construed as being limiting in any way.
The breast pump shield 100 shown in FIG. 1 has been described as including one cover 104, one breast engagement portion 106, one throat portion 112, one suction chamber 114, and one inlet 116. It should be understood, however, that some embodiments of the breast pump shield 100 can include zero, one, or more than one cover 104, zero, one, or more than one breast engagement portion 106, zero, one, or more than one throat portion 112, zero, one, or more than one suction chamber 114, and/or zero, one, or more than one inlet 116. In one contemplated embodiment, for example, the breast pump shield 100 can include a truncated breast engagement portion or can omit the breast engagement portion 106 altogether, thereby resulting in a short and compact breast pump shield 100 that essentially consists of the throat portion 112 and the suction chamber 114. It should be understood that this example is illustrative and therefore should not be construed as being limiting in any way.
Turning to FIGS. 2A-2B, additional details of the breast pump shield 100 are illustrated and described in detail. In particular, FIGS. 2A-2B are line drawings illustrating top elevation views of a breast pump shield, according to another illustrative embodiment of the concepts and technologies described herein. Because the various components of the breast pump shield 100 can be arranged in various configurations, it should be understood that the views shown in FIGS. 2A-2B could also correspond to side elevation views and/or bottom elevation views instead of, or in addition to, top elevation views.
As shown in FIG. 2A, some embodiments of the breast pump shield 100 can include an expandable and/or collapsible throat portion 112. In various embodiments, the expandable and/or collapsible throat portion 112 can include an expandable and collapsible ridged portion (hereinafter referred to as a “ridged portion”) 200. The ridged portion 200 can be collapsed or expanded based on desires or needs of a user. In the embodiment shown in FIG. 2A, the ridged portion 200 of the throat portion 112 is illustrated as being collapsed, while in FIG. 2B, ridged portion 200 of the throat portion 112 is illustrated as being expanded. It should be understood that these examples are illustrative and therefore should not be construed as being limiting in any way.
In some embodiments, the ridged portion 200 can be included on the breast pump shield 100 to collapse the breast pump shield 100, at least partially, to make the size of the breast pump shield 100 compact. Thus, when the ridged portion 200 is collapsed, the breast pump shield 100 may consume less space in a diaper bag, glove compartment, purse, or other area for convenience. In some embodiments, the ridged portion 200 also can be used to protect the lubricant layer. In particular, the ridges of the ridged portion 200 can be used to hold or retain the lubricant used to provide the lubricant layer at a desired location. It should be understood that this example is illustrative and therefore should not be construed as being limiting in any way.
In some embodiments, an example of which is shown in FIG. 2B, the breast pump shield 100 can include support structures such as the supports 202 and the support rods 204. According to various embodiments, the supports 202 and/or the rods 204 can be formed from plastics, metals, alloys, thermoplastics, acrylics, epoxies and/or resins, wood, glass, and/or other materials. The support structures can be used to hold the breast pump shield 100 in a configuration at which the ridged portion 200 is expanded. It can be appreciated that the suction generated by the breast pump (whether manual or electronic) can be sufficient to collapse the ridged portion 200, which can reduce the realized suction at the nipples of the user. Thus, some embodiments such as the example shown in FIG. 2B include the support structures. In some embodiments, the rods 204 can be removable and/or reusable. As such, the rods 204 can be removed, and the ridged portion 200 can be collapsed, if desired.
Although not visible in the FIGURES, some embodiments of the concepts and technologies described herein include additional supports 202 and rods 204. In particular, supports can be located near the ring 110 and near the bottom of the breast engagement portion 106 (near the beginning of the throat portion 112). Thus, some embodiments of the concepts and technologies described herein can make use of collapsible and/or soft or semi-soft materials for the body portion 102. A collapsible or semi-collapsible body portion 102 can be provided with support by the supports 202 and rods 204. It should be understood that these examples are illustrative and therefore should not be construed as being limiting in any way.
Turning now to FIG. 3, additional aspects of the concepts and technologies described herein for a breast pump shield will be described in detail. In particular, FIG. 3 is a line drawing illustrating cut-away view of the throat portion 112 of the breast pump shield 100 as viewed from the cut-line A-A shown in FIG. 1, according to some illustrative embodiments of the concepts and technologies described herein. It should be understood that this example is illustrative and therefore should not be construed as being limiting in any way.
As can be seen in FIG. 3, the throat portion 112 can include a lubricant layer 300 disposed within the throat portion 112. In some embodiments, the lubricant layer 300 can be located between an inner surface (not labeled in FIG. 3) of the throat portion 112 and a void 302 of the throat portion 112. As mentioned above, it can be appreciated that the void 302 can accommodate a nipple of a lactating mother during pumping and/or use of the breast pump shield 100. As such, in some embodiments the lubricant layer 300 can be included to lubricate the inner surface of the throat portion 112. The lubricant layer 300 can be included to prevent irritation of the nipples, which can result from pumping. Similarly, the lubricant layer 300 can be included to reduce pain, which some women may experience when pumping. Still further, the lubricant layer 300 can be included to allow the nipple to slide up and down along the side wall of the throat portion 112, which can stimulate the nipples and encourage milk flow. It should be understood that these examples are illustrative and therefore should not be construed as being limiting in any way.
The functionality of the lubricant layer 300 can be provided, in some embodiments, by a food grade and/or hypoallergenic lubricant. Thus, the lubricant layer 300 can be safe for use during lactation as any amounts (trace or otherwise) that pass into the expressed or pumped breast milk may not pose a risk to an infant, toddler, or other child or children who consume the milk produced using the breast pump shield 100. According to one contemplated embodiment, the lubricant used to provide the lubricant layer 300 can include a coconut-based lubricant. According to another contemplated embodiment, the lubricant used to provide the lubricant layer 300 can include a palm-based lubricant. According to another embodiment, the lubricant used to provide the lubricant layer 300 can include a fruit-based or vegetable-based lubricant such an olive-oil-based lubricant, a vegetable-oil-based lubricant (e.g., canola oil, soy oil, peanut oil, corn oil, avocado oil, safflower oil, sunflower oil, etc.), nut oils (e.g., almond oil, walnut oil), other oils (e.g., cottonseed oil, sunflower oil, etc.) combinations thereof, or the like. According to other embodiments, the lubricant used to provide the lubricant layer 300 can include other oils and/or lubricants such as petroleum based and/or mineral-based lubricants. According to still other embodiments, the lubricant used to provide the lubricant layer 300 can include flax oil or fish oil, which can be high in Omega-3 fatty acids that are known to encourage healthy brain development of infants. Thus, oil that leaks into the milk can actually be beneficial for the infant, in some embodiments. Because other oils and/or lubricants can be used, it should be understood that the above examples are illustrative and therefore should not be construed as being limiting in any way.
According to various embodiments, the lubricant layer 300 can be provided by a thick heat-resistant lubricant. As such, during shipping and/or other transportation of the breast pump shield 100, the lubricant layer 300 may not move or run. This functionality can be particularly useful when shipping the breast pump shield 100 in a high heat environment, or the like. As such, the breast pump shield 100 can be ready for use without applying lubricant to the breast pump shield 100, a component thereof, and/or a nipple or breast of the lactating mother. In some embodiments, the lubricant or oil used to provide the lubricant layer 300 can be thickened using various processes to prevent running and/or melting of the lubricant. It should be understood that this example is illustrative and therefore should not be construed as being limiting in any way.
Referring now to FIGS. 4A-4B, additional aspects of the concepts and technologies described herein for a breast pump shield 100 will be described in detail. In particular, FIG. 4A illustrates a cross section of the cover 104, viewed along the cut/view line B-B shown in FIG. 2B. It can be appreciated that a cross section view of any portion of the cover 104 can be substantially similar to the view shown in FIG. 4A. Additionally, FIG. 4B illustrates an assembly drawing of the cover 104. Collective reference will be made to FIGS. 4A-4B to describe the cover 104 and/or the components thereof.
As shown in FIGS. 4A-4B, the cover 104 can include multiple layers. According to various embodiments of the concepts and technologies described herein, the cover 104 can include two or more layers. According to some other embodiments, the cover 104 can include three or more layers. In the illustrated embodiment, the cover 104 includes three layers. Based upon the foregoing, it can be appreciated that the illustrated embodiment is illustrative and therefore should not be construed as being limiting in any way.
The cover 104 shown in FIGS. 4A-4B includes a wiping layer 400, a support layer 402, and a lubricant layer 404.
