Breast milk extraction system for nursing mothers

Abstract

A breast milk extraction system is disclosed, which includes a jaw mechanism that can mimic the suckling motion of an infant. The jaw mechanism includes an upper jaw coupled to a lower jaw wherein the coupling mechanism allows the lower jaw to create a thrusting motion such that when applied to a breast the lower jaw massages the breast below a nipple region to effectively engage the mammary glands to produce milk. The system further includes a synthetic tongue that mimics the tongue motion of a breastfeeding infant to further achieve biomimicry.

Description

BREAST MILK EXTRACTION SYSTEM FOR NURSING MOTHERS

[0001] The disclosure generally relates to the extraction of breast milk using a breast pump. More particularly, the disclosure relates to a breast milk extraction system for nursing mothers.

[0002] Breastfeeding provides essential nutrients and antibodies that support infant health and development. However, many mothers face challenges in maintaining a consistent breastfeeding routine due to work commitments, medical conditions, or other personal circumstances. In the case of premature babies, mothers are often suggested to “dry pump” to stimulate milk expression. To address these challenges, breast pumps have become an essential tool, allowing mothers to express and store breast milk for later use.

[0003] Traditional breast pumps, whether manual or electric, help facilitate milk expression, yet they come with certain drawbacks. Many mothers experience discomfort, isolation and discontent due to time-constraints and amount of yield during the process of milk expression. Which leads to psychological and emotional setbacks that impacts the efficacy of pumping.

[0004] Breast pumps have remained nearly the same since their invention in 1854. They utilize a pulsating vacuum to force milk extraction from the nipple milk ducts. However, in many cases this causes damage to the milk ducts in the breast that can cause soreness and potentially damage. This invention utilizes biomimicry to copy the actions of a nursing baby’s mouth to massage and apply zonal pressure to extract milk from a mother’s breast in a natural process like what baby does.

[0005] This section is intended to introduce some aspects of the present disclosure in a simplified manner.

[0006] In one general aspect, device may include a frame having movable portions arranged to simulate a human mouth, the frame may include an upper jaw portion, lower jaw portion, and linkages connecting the upper and lower jaw portions permitting a cyclical undulating movement therebetween. Device may also include a drive unit having an electric motor coupled to the linkages and arranged to drive said cyclical undulating movement, where said movement includes a first path along a distal projection to a maximally opened position, followed by a second path closing the jaw portions to a minimally opened position, followed by a third path along a proximal retraction.

[0007] Implementations may include one or more of the following features. Device where the lower jaw portion is wedged-shaped at its distal end. Device where the upper and lower jaw portions are arch-shaped, with an apex of the arch-shaped jaw portions projecting distally and ends of the arch-shaped jaw portions connecting to the frame proximally. Device where the lower jaw portion and linkages compose a 4-bar linkage arranged to permit said cyclical undulating movement. Device where the lower jaw portion and linkages compose a 3-bar linkage with slider for the lower jaw portion, being arranged to permit said cyclical undulating movement. Device where the lower jaw portion and linkages compose a cam-follower arranged to permit said cyclical undulating movement. Device may include a drive controller arranged to periodically pause the electric motor for a period mimicking a suckling baby. Device where the upper jaw portion is fixed relative to the drive unit. Device where the upper and lower jaw portions are 70-30mm apart in the maximally open position, where the second path closing the jaw portions is 20-30mm, and where the distal projection is 20-30mm. Device may include a collection bag inside the frame with a bag opening located at distal regions of the lower and upper jaw portions, preferably said bag opening having flanges contacting lip portions and / or said jaw portions, preferably where the collection bag is fed through the lower and upper jaw portions into an esophagus region of the frame. Device may include a silicone layer covering distal regions of the upper and lower jaw portions, preferably shaped to simulate lips. Device may include a tongue portion of the frame, connected to and driven by a second drive unit and arranged to move the tongue portion relative to the upper jaw portions, preferably arranged to move in unison with the lower jaw portion, more preferably where the tongue portion moves with peristaltic motion.

[0008] In one general aspect, a method may include contacting a device simulating a human mouth to a woman’s breast, the device having a drive unit and a frame having upper and lower jaw portions. Method may also include operating the drive unit to move upper and lower jaw portions relative to each in a cyclical undulating movement, said movement includes a first path thrusting the lower jaw portion into the breast to a maximally opened position, followed by a second path closing the jaw portions to a minimally opened position, then followed by a third path retracting the lower jaw portion.

[0009] This summary does not necessarily describe the entire scope of all aspects. Other aspects, features, and advantages will be apparent to those of ordinary skill in the art upon review of the following description of specific embodiments.

[0037] In the following description, associated drawings, included claims, and other parts of the document, various details are set forth to provide a detailed understanding of the disclosure and embodiments thereof. It will be apparent, however, that the disclosed embodiments may be practiced without some of these details. Several features described hereafter can each be used independently of one another or in combination with other features.

[0038] Research highlights the unique benefits of milk from mothers of premature babies. This milk contains higher levels of growth factors compared to donor milk, which is often from older babies’ mothers and pasteurized, potentially affecting some of its beneficial properties. While donor milk is still superior to formula, high-dose feeding with maternal milk during the neonatal period has been shown to reduce risks such as enterocolitis, improve growth and neurodevelopment, and minimize other morbidities, as well as reduce costs of Neonatal Intensive Care Units (NICUs).

[0039] The breast pumps in use today have not had any significant design changes since their invention in 1854. They have graduated from manual pumping designs to motorized extraction systems but the principle of milk extraction from the breast has remained the same (i.e.,suction). Breast pumps rely on a vacuum process only to pull the milk from the pores in the nipple of a mother and utilizing a pulsing mode to attempt to force the milk ducts to open and allow milk to transfer into the nipple region between vacuum extraction cycles. The breast is not stimulated further and only a tapered spout (which is very sensitive to measurement of the nipples) is used to fit over the nipple to provide a pressure seal (which needs to be held by hands or a bra) and direct the flow into the storage container portion of the pumping system. This creates stress on the milk ducts, sucks out thinner milk which leads to a gassy baby and fatty material buildup within the milk ducts and can cause injury to the mother’s breast leading to the stoppage of milk production and inflammation making nursing difficult.

[0040] Infants use their tongue and perioral muscles to latch to the breast by forming a seal around the nipple and areola. A baseline vacuum of approximately − 64 mmHg is applied, and inferior tongue movement to the lowest point from the palate coincides with creation of the strongest (peak) vacuum, on average − 145 mmHg, typically resulting in milk flow into the oral cavity. Hospital-grade pumps generally have a vacuum strength of between 300 and 350 mmHg, while personal pumps are typically between 200 to 300 mmHg.

[0041] Suction corresponds to the negative intraoral pressure generated with closure of the nasal passages by the soft palate, lips tightening around breast, and the lowering of the lower jaw. With no air penetration into an increased volume of the oral cavity, milk is drawn into the mouth. Expression corresponds to the compression or stripping of the breast nipple by the tongue against the hard palate to eject milk into the mouth.

[0042] shows, in perspective view, a typical breast pump100with a pulsating vacuum system102applying a periodic suction force on the mother’s breast via a vacuum sealing flange104that contains an opening for the nipple to be inserted and milk to be collected in bottles106. The suction is applied to this collection system via hoses going from the pulsating vacuum system102to the back end of the flange104that can also act as the cap of each collection bottle106.

[0043] shows, in perspective view, another type of known breast pump with similar components asbut is laid out in a more integrated form with the same function being provided to the breast. It contains the nipple in a fixed shaped tube to collect and direct the extracted milk into a container, which in this case is a removable plastic bag. Where the system inis designed to have a single pump with separate collection components for each breast, the system inis comprised of two independent systems with separate but identical components.

[0044] Both systems ofandprovide only a pulsating vacuum suction to the nipple of the breast that causes strain on the milk ducts in the nipple due to the force of the vacuum extracting the milk from the reservoir chambers in the nipple while also causing a low pressure around the nipple. This low pressure expands the nipple and stresses the chambers. These valves are designed to be opened by pressure and relaxation cycles during nursing that are opening the milk pores in the nipple while applying pressure to the breast and nipple base to push the milk out of the nipple into a baby’s mouth. Suction in a baby’s nursing is only one aspect of the milk extraction and is not very strong. For modern breast pumps to rely solely on suction is a testament to the lack of design review of these products and therefore there is a need in the art to improve the design and functionality of breast pumps.

[0045] Successful breastfeeding requires dynamic synchronization between the oscillation of the infant's mandible, rhythmic motility of the tongue, and the breast's milk ejection reflex that drives maternal milk toward the nipple outlets. During suckling, the infant compresses the areola region and the underlying tissue with the tongue interposed between the lower gum and breast. Sub-atmospheric oral pressures are generated via the oscillating mandible and pulsating tongue. The tongue muscle plays a key functional role in the regulation of optimized extraction and swallowing of human milk from the breast.

[0046] The terms “coupled”, “coupling”, “connected”, “attached”, “latched” or “applied” as used herein can have several different meanings depending on the context in which these terms are used. For example, the terms coupled, coupling, or connected can have a mechanical or electrical communication connotation. For example, as used herein, the terms coupled or coupling, can indicate that two parts or devices are directly connected to one another or indirectly coupled to one another through one or more intermediate elements or devices via a mechanical element depending on the particular context. For example, as used herein, the term connected can indicate that two components are directly connected to one another. For example, the terms, latched, attached or applied can have a physical communication connotation. For example, as used herein, the terms latched, attached or applied, can indicate that a device or part of a device are directly connected to a human or indirectly coupled through one or more intermediate elements or devices via a physical element depending on the particular context.

[0047] The terms “distal” or “proximal” are used to describe motion or locations away from or towards the main body, depending whether this describes the perspective of the mother, baby, or breast pump.

[0048] The word “a” or “an” when used in conjunction with the terms “comprise”, “include”, “comprising”, or “including” in the claims or the specification may mean “one”, “one or more”, “at least one”, and “a plurality” unless the content dictates otherwise. Similarly, the word “another” means “additional” or “at least a second” unless the content clearly dictates otherwise.

[0049] In accordance with the present disclosure, the term “jaw” is described as a mandibular structure or maxillofacial component, where the lower / bottom jaw can also be referred to as the mandible and the upper / top jaw can also be referred to as the maxilla. The jaw can be a mechanical structure including upper and lower jaw components and / or a mechanical tongue that mimics a human jaw structure.

[0050] As used herein, the terms “upper jaw” and “top jaw” and the like refer to the same interpretation and may be interchangeably used throughout the specification.

[0051] As used herein, the terms “lower jaw”, “bottom jaw”, “mandible” and the like refer to the same interpretation and may be interchangeably used throughout the specification.

[0052] The present disclosure includes a system for milk extraction from the breast that mimics the jaw motions including mouth, tongue, etc. of a nursing baby. The present system allows for nursing mothers to express breastmilk in the same manner as if it is the baby nursing rather than a pumping system. This allows less vacuum to be utilized since the milk ducts are stimulated to enlarge, allowing better milk flow, applying pressure at various positions and in the cyclic order that a baby’s mouth and tongue perform the milking process, thereby allowing the milk to flow into the enlarged ducts within the nipple and then extract the milk with a combination of applied pressure and light vacuum to produce a natural sucking and milking process that matches the design of the breast and milk ducts.

[0053] The present disclosure therefore improves milk flow, reduces the buildup of fatty material in the milk ducts, and eliminates the strain, inflammation, and potential damage to the mother’s breast. It also increases the commonality of the nursing and milking experience of the breast, thereby improving the amount and quality of the milk being pumped to better match that which the baby receives when nursing.

[0054] Embodiments of the present disclosure relate to a breast milk extraction system for nursing mothers.

[0055] shows, in isometric view, parts of a breast milk extraction system, in accordance with the present disclosure. In some embodiments, additional parts can be included. In another embodiment, some parts can be omitted and yet in another embodiment some parts can be combined. When assembled, the breast milk extraction system can be applied to a breast as shown in, for example,and. The parts of the breast milk extraction system can include upper jaw assembly210, lower jaw assembly230and rotary input240. In some embodiments, rotary input240can be, for example, a crank, a swing mechanism, etc. When assembled, rotary input240couples the upper jaw assembly210to lower jaw assembly230towards a proximal end wherein the proximal end relates to the end that is in close proximity to a nursing infant’s mouth.

[0056] shows, in isometric view, a breast milk extraction system300andshows, in isometric view, the breast milk extraction system300viewed from another angle. In some embodiments, breast milk extraction system300can include a jaw mechanism which mimics the suckling motion of a baby involving jaws, tongue, chin, cheeks, lips, etc. As explained in, breast milk extraction system300can include an upper jaw assembly210, a lower jaw assembly230and a rotary input240coupled together at various locations such that the breast milk extraction system300acts as a 3-bar linkage with slider system.

[0057] Upper jaw assembly210can include upper jaw212which extends from both sides of coupling means214and is curved / free of rough edges. As shown inand, coupling means214can include an outer component216, mid component218(not shown in) and inner component220on either side of coupling means214where the outer component216and inner component220are coupled via the mid component218. In other words, the outer component216, inner component220, mid component218and upper jaw212are interconnected members of the same structure (i.e.upper jaw assembly210). When applied to a breast, upper jaw212can be placed above the nipple region, as shown in, for example,and. Upper jaw assembly210further includes motor222, power supply (not shown) and a plurality of gears224.

[0058] Lower jaw assembly230can include lower jaw232which can be a protruding portion that is curved / free of rough edges. In some embodiments, lower jaw232is designed to extend farther than the upper jaw212such that when applied to a breast, lower jaw232covers a larger surface area of the breast than the upper jaw212. Therefore, when the breast milk extraction system300is applied to a breast, the lower jaw232can be placed below the nipple region, as shown in, for example,and.

[0059] As shown in, rotary input240can be designed such that when assembling lower jaw assembly230is able to receive a portion of rotary input240at hole234. Similarly, upper jaw assembly210is able to receive at least a portion of rotary input240at the corresponding hole(s) (not shown) of upper jaw assembly210such that the upper jaw assembly210and lower jaw assembly230are coupled together via rotary input240towards to proximal end of the breast milk extraction system300.

[0060] ,,,show, in side view, the breast milk extraction system300. As shown in,and, lower jaw assembly230ofcan further include a plurality of slits 536 spanning along a portion of either side of lower jaw assembly 230. In some embodiments, plurality of slits 536 is designed to receive a portion of the mid component 218 ofsuch that the upper jaw assembly 210 is also coupled to the lower jaw assembly 230 on a medial location of the breast milk extraction system 300. The plurality of slits 536 coupled to a portion of the mid component 218 of the upper jaw assembly 210 therefore allows the lower jaw 232 to slide forward and backwards. Furthermore, the rotary input 240 coupled to the lower jaw assembly 230 allows the lower jaw 232 to rotate.

[0061] Typically, the suckling motion of a baby is a rhythmic, cyclic motion including open mouth, extend lower jaw, and retract.,,andshow, in side view, the breast milk extraction system300at different lower jaw232displacements along the plurality of slits536(plurality of slits536is not shown in). The breast milk extraction system300ofmimics the jaw position of a breastfeeding baby when the baby’s mouth is partially open. Similarly, the breast milk extraction system 300 ofmimics the jaw position of the baby when the baby’s mouth is fully open. The breast milk extraction system 300 ofmimics the jaw position of the baby when the baby’s lower jaw is extended and the breast milk extraction system 300 ofmimics the jaw position of the baby when the baby’s bottom jaw is retracted. The repetition of this rhythmic motion allows for biomimicry of a breastfeeding infant which stimulates the mammary glands of a breastfeeding woman to produce milk and directs milk flow from the mammary glands to the nipples.

[0062] The jaw portions and mechanical assemblies are designed to provide a cyclical and undulating movement. The cyclical movement denotes continuous movement to simulate continuous feeding. Undulating is intended to denote a smooth rising and failing relative motion of the jaw portions, typically of the lower jaw relative to the fixed upper jaw portion and remaining frame.

[0063] The movement is intended to be smooth and may be described by a series of connected splines or paths, which generally includes a first path along a distal projection to a maximally opened position, followed by a second path closing the jaw portions to a minimally opened position, followed by a third path along a proximal retraction. The cycle then repeats.

[0064] Similar to a human mouth, the upper and lower jaw portions are arch-shaped, with an apex of the arch-shaped jaw portions projecting distally away from the frame and the base connecting to the rest of the frame proximally. To achieve the prodding signal of a babby, the lower jaw portion is preferably wedged-shaped at its distal end. The arch shape and wedge shape are best shown in parts 212 and 232 ofand.

[0065] Furthermore, the dimensional range of the lower jaw’s232motion can be designed to match that of a baby. The upper and lower jaw portions and mechanical assembly may be sized, such that the distal ends of the jaw portions are between 30 and 70mm apart in the maximally open position in order to mimic large to small mouths. The arrangement of mechanical assembly components preferably provide a closing motion between the upper and lower jaw portions of between 20 and 30mm, which is typically sufficient to express the milk retained in the distal chamber of the breast. The mechanical assembly preferably is arranged to thrust the lower jaw portion in a distal projection of between 20 and 30mm.

[0066] The breast milk extraction system300can thus be a mechanical assembly where the upper jaw assembly210remains stationary, and the lower jaw assembly230which includes lower jaw232is configured to open, extend, and retract through a series of articulated movements. The lower jaw assembly230operably coupled to a pivoting mechanism (e.g.rotary input240of), enables its controlled displacement relative to the upper jaw212. In some embodiments, breast milk extraction system300utilizes at least three interconnected linkage members (e.g.upper jaw assembly210, lower jaw assembly230and rotary input240), each functioning to guide the motion of the lower jaw232with precision. Actuation of the lower jaw assembly230can be achieved via mechanical, hydraulic, or pneumatic means, providing a controlled range of movement.

[0067] In the preferred embodiment, the lower jaw assembly230is driven by motor222, which is controlled by a drive controller to provide precise control over its movement. The plurality of gears224, operably coupled to the motor222, can facilitate regulated motion transmission to the lower jaw assembly230. For example, the motor222rotates gear224a, which in turn rotate gear224b. This motion transmission allows the rotation of rotary input240coupled to the lower jaw assembly230. Rotary input240is responsible for controlling distinct aspects of the lower jaw’s232displacement, including opening, extension, and retraction. The rotational and sliding motion of the lower jaw232achieves the thrusting and massaging of the breasts that helps direct milk to flow from the mammary glands to the nipples of a breastfeeding woman. The breast milk extraction system300is thus able to mimic the repetitive motion of open, extend and close mouth of a breastfeeding infant.

[0068] In some embodiments, the power supply (not shown) is an external power supply. In contrast, in other embodiments, the power supply is on-board power source(s) such as batteries, ultra-capacitors or photovoltaic cells capable of powering motor222and the drive controller.

[0069] In some embodiments, the cyclical motion of the lower jaw232can be adjusted via a feedback loop in the drive controller adjusting the speed / pattern of motion of motor222. This gives the user more control over the breast milk extraction system300according to their needs. The drive controller can add periodic pauses to the motor to mimic a suckling baby, who tend to rest after several swallows.

[0070] Therefore, in some embodiments, the breast milk extraction system300can incorporate sensors or feedback controls to control the jaw movement, enhance operational accuracy and responsiveness. In some other embodiments, the breast milk extraction system300can include a heating element that can dissipate heat to at least a portion of the lower jaw232and upper jaw212. The heating element can be designed with temperature sensors to regulate its temperature to mimic the body heat of a baby (e.g.in the range of 97.9 - 100.4 degrees Fahrenheit).

[0071] Turning towhich shows, in isometric view, a breast milk extraction system600in accordance with the present disclosure.In, at least a portion of the breast milk extraction system300as shown in,,,,andis enclosed by a cover 650. In some embodiments, cover 650 can be designed to function as a baby’s mouth including lips, cheeks, tongue, etc. The cover 650 can include an inlet 652 and an outlet (not shown). The inlet 652 of the cover 650 can formed as flange to provide a wide opening that fits over a woman’s breast, creating a seal around the nipple and areola. The outlet (not shown), on the other hand, is a narrower end located proximal to the simulated infant’s mouth which allows the nipple portion of the breast to extend into the outlet, directing the expressed milk into, for example, a collection container.

[0072] Therefore, cover650applied to the breast milk extraction system300can act as a flange that provides a secure fitting of the breast milk extraction system300over a woman’s breast at inlet650and guides the expressed milk through the outlet (not shown) to a collection container.

[0073] shows, in side view700, the breast milk extraction system300applied to a woman’s breast702.shows, in side view800the breast milk extraction system600applied to a woman’s breast702. As shown inand, upper jaw212is placed above the nipple region. During operation, upper jaw212remains is stationary. The lower jaw232is placed below the nipple region of the breast702. During operation, lower jaw212creates a thrusting and swing motion that massages the breast tissue which achieves biomimicry of a breastfeeding baby. This allows the expressed milk to flow from the breast702to the nipple rather than suction applied at the nipples. As shown in, the cover650provides a secure and comfortable seal over the breast702and helps direct the expressed milk out through the outlet (not shown) of the cover650without spilling or leaking. The enlarged structure of lower jaw232compared to the upper jaw212is able to cover a larger surface area of the breast702below the nipple region which thereby increases yield.

[0074] In some embodiments, cover650can be designed to accommodate a disposable bag (not shown) for milk expression. This allows the disposable bag to act as a direct collection system, eliminating the need for frequent cleaning of the breast milk extraction system600. In such embodiments, the inlet652, which forms a secure seal around the breast702, can be equipped with a mechanism that holds the bag in place, ensuring seamless milk transfer. The outlet (not shown) then directs the expressed milk directly into the bag, preventing contact with the surfaces of breast milk extraction system 600including cover650and minimizing contamination risks.

[0075] In some embodiments, cover650can be designed to accommodate both disposable bags and reusable bottles which offers ultimate flexibility and convenience for milk expression. This hybrid system allows parents to choose between the ease of single-use storage or the sustainability of reusable containers, depending on their needs. The inlet652, which forms a secure seal around the breast702, can support both storage options with an adjustable attachment mechanism (not shown). Meanwhile, the outlet (not shown) seamlessly directs expressed milk either into a disposable bag or a reusable bottle, preventing unnecessary spills and contamination.

[0076] When using a disposable bag, milk flows directly into a pre-sterilized, sealable pouch, eliminating the need to clean cover652after each use. These bags can be securely attached, easily detached, and stored without requiring milk transfer. On the other hand, opting for a reusable bottle provides an eco-friendly alternative that minimizes waste. In some embodiments, the breast milk extraction system600may feature a quick-connect system that allows bottles of varying sizes to securely couple to the breast milk extraction system600, ensuring direct milk collection without any leaks.

[0077] For purposes of illustration, distal end of the breast milk extraction system300may be referred to as the portion of the breast milk extraction system300that is further away from a nursing infant’s mouth. Similarly, the proximal end of the breast milk extraction system300may be referred to as the portion of the breast milk extraction system300that is in close proximity to a nursing infant’s mouth. The same principle can be applied to the breast milk extraction system600.

[0078] In some embodiments, the cover650includes a web of material that holds and seals the breast(s)702during use. It can be flexible yet durable and can be made of a material including silicone, thermoplastic elastomer, rubber, etc. Cover650can be made of a single web of material or a combination of materials. In some embodiments, cover650can have a uniform dimensional thickness. In some other embodiments, cover650can have a differing localized dimensional thickness resulting in differing hardness. For example, a portion of cover652which encloses a portion of the upper jaw212can be made of a softer material such as silicone with a hardness of 10-50 on the Shore A scale.

[0079] while a portion of cover652which encloses a portion of the lower jaw232can be made from a thicker, softer material such as silicone with a hardness of with a range of 10-50 on the Shore 00 scale.

[0080] Cover650therefore provides various advantages, including attachment of the breast milk extraction system300to a breast, convenient milk flow from the nipples to a suitable milk collection system as well as comfort and durability due to the materials used.

[0081] In some embodiments, the lower jaw assembly230as well as some components of the upper jaw assembly210(e.g.upper jaw232, coupling means214) can be made of a lightweight yet durable material to ensure quality, comfort and ease of handling. In some embodiments, a plastic such as medical grade, ABS-blend plastic can be used.

[0082] In some embodiments, the thrusting and swing motion of the lower jaw232can be achieved in several different ways. For example, the lower jaw232can be designed as a protrusion following a cyclical motion. In some embodiments, the cyclical motion can be achieved with the use of four-bar linkage system as shown in, dual servo mechanism as shown in,B,C, or a combination thereof.

[0083] In some embodiments, biomimicry of the suckling motion can also be achieved with a mechanical tongue. In some embodiments, the mechanical tongue can act as the lower mandible. In some other embodiments, the tongue can be used as an additional component of the breast milk extraction system. The addition of the mechanical tongue may enhance the biomimicry aspect of suckling.

[0084] In accordance with the present disclosure, a breast milk extraction system is further described in relation to, at least,,,,,,,,,and.

[0085] includes a plurality of technical diagrams910illustrating aspects of the physiology and interactions of a mouth and a breast. The plurality of technical diagrams910includes a plurality of ultrasound images910Aof a baby’s mouth during nursing on a mother’s breast. See diagram910A1, diagram910A2, and diagram910A3on the left side of plurality of technical diagrams910showing a plurality of body parts at three points during the nursing process.

[0086] As illustrated in plurality of ultrasound images910Athe plurality body parts include an upper pallet900, a nipple901, and a baby’s tongue902. Each of upper pallet900, nipple901, and baby’s tongue902has a pose or position defined by a respective periphery overlaid on plurality of ultrasound images910A. For concreteness a respective periphery is referenced by the associate body part.

[0087] As shown in diagram910A1, nipple901includes full milk ducts at the point where the distance between upper pallet900and the tongue902are at their widest, and as the distance between the tongue and pallet closes the nipple is compressed and the milk has been extracted.

[0088] Comparing the positions of the body parts in diagram910A1, diagram910A2, and diagram910A3the expression of milk is a natural process which involves motions of the jaw (e.g., upper pallet900), and tongue902to transfer the milk from the breast into the nipple901, and then extract the milk (not shown). Applicant believes this natural method is a gentler and more efficient milking process.

[0089] In the central column of, the plots labeled B and C (diagram910Band diagram910C) show various position and movements of pallet900and tongue902. The remainder of the plot in technical diagrams910(such as diagram910D) show the intensity and frequency of these movements. For more information see C.W. Gennaet al. 2021 “Quantitative imaging of tongue kinematics during infant feeding and adult swallowing reveals highly conserved patterns”PhysiolRep.2021 Feb;9(3):e14685. doi: 10.14814 / phy2.14685.

[0090] shows a plurality of tongue902movements, each at a sequential step during the nursing process depicting the various positions of the tongue902and how the front middle and back of the tongue902move. As shown,the tongue902initially is higher toward the front of the mouth and then translates that height toward the back of the mouth drawing the milk out of the nipple and into the baby. Using this information, the applicant has designed a further embodiment of a breast milk extraction system that utilizes biomimicry to improve the efficiency of the pumping system, reducing the physical stress to the breast and psychological stress to the mother that can be caused by the breast pumps available today.

[0091] shows, in side view, a three-dimensional rendition1100depicting the positional relationship of a mother’s breast702, the nipple901and the baby’s tongue902. In some embodiments, a synthetic tongue can be housed in the breast milk extraction system of the present disclosure to mimic the tongue movement of a baby during breastfeeding.

[0092] shows a technical diagram of a synthetic tongue1200, with an insert1206that provides the ability to stiffen and allow direction of the tongue1200when movement is required. In some embodiments, the synthetic tongue1200can include tongue cover1202. Tongue cover1202can be made of silicone or a similar soft and somewhat deformable material. In some embodiments, the insert1206may also be made to have electrical heating elements patterned down its length and thermal sensors to provide feedback control to provide the tongue with the same temperature as a baby’s mouth. In a similar fashion the upper pallet900of, can also be provided with a heating element to create the same thermal environment that the breast and nipple of a mother would experience when nursing a real baby. Flexible points such as a plurality of hinges1204along the length and across the width of the insert1206provide the ability to curve the tongue along its length and to form a depression across its width, thereby allowing the synthetic tongue1200to move and take the shapes that a normal tongue is capable of.

[0093] shows a technical diagram of the synthetic tongue1200including mechanical control of the tongue’s movement by a plurality of anchoring cables1306at plurality of points1305near the tip of the tongue, and directing the cables through a plurality of guides1307to ensure that the plurality of cables1306remain in position during motion. When tension is applied to shorten one of the cables the force will be applied to the stiffener (i.e.insert1206) inside the tongue material and cause it to bend at the flexing points (e.g.plurality of hinges1204), thereby moving the tongue as desired.

[0094] shows a technical diagram of another embodiment of the motion control of a synthetic tongue1400where pressure or release of pressure can be utilized to inflate a plurality of small chambers1408along the synthetic tongue1400thereby providing the motive force to cause the tongue to flex as described previously. In this embodiment either a gas (i.e.air) or a liquid may be used to inflate the plurality of chambers1408which can be directed by an external source from the synthetic tongue1400to the plurality of chambers1408via a plurality of channels1409.

[0095] shows a side view1550of a breast milk extraction system when applied to a woman’s breast, in accordance with parts of the present disclosure. A flange1500for fitting against the breast has an aperture in its center for placement of the nipple. The flange can be one size fits all like a baby’s mouth. A structure of a breast milk extraction system acts as the upper mandible or upper jaw1501of an infant and is connected by an arm or plate1502to a vertical frame1504via a hinge1503or mounted in a fixed format to the vertical frame1504.

[0096] An upper pallet1505may be an extended as part of the flange1500or be a separate piece that is affixed to the flange1500. An anchor1506for a synthetic tongue1510is connected to the vertical frame1504to provide the tongue with positional alignment forming the mouth region of the breast milk extraction system. Hinge1507of the lower mandible or lower jaw1509provides vertical movement for the arm or plate1508and the lower mandible or lower jaw1509.

[0097] The synthetic tongue1510is connected to the lower mandible or lower jaw1509providing a second anchor and ensuring its position in the mouth region of the breast milk extraction system and positioning the tongue to extend past the lower mandible or lower jaw1509as an infant’s tongue does during nursing.

[0098] An inflatable chamber1511is positioned under the synthetic tongue1510and anchored to an arm1508to correctly position it for deflection of the tongue in a vertical manner as it is filled with either a gas, such as air, or a fluid, such as water. Such deflection in an upward direction flexes the synthetic tongue1510in a mid-section causing a stiffener plate (e.g.insert1513) inside the synthetic tongue1510to adjust the position of the synthetic tongue1510from its tip to its back anchor in the normal manner that an infant’s tongue would.

[0099] In some embodiments, a plurality of inflatable chamber such as inflatable chamber1511can be used to cause the synthetic tongue1510to lift higher on the outside edges of the tongue than a central region causing the synthetic tongue1510and its insert1513to shape the form of the tongue into a shallow “V” adding in the direction of the milk expressed from the nipple toward the back of the breast milk extraction system. Similar to an infant’s mouth, the breast milk extraction system of the present disclosure can have an underbite of the mandibles where the lower jaw1509extends slightly forward of the upper jaw1501. This positioning can allow the breast milk extraction system to apply pressure to the breast and nipple during the pumping process in the same manner as a nursing infant.

[0100] The tip1512of the synthetic tongue1510extends slightly from the lower jaw1509again in a biomimicry of an infant aiding the application of pressure from the synthetic tongue1510to the lower side of the nipple region1516during the breast milk expression process. By coordinating these motions into a cycle of compression and expansion, the nipple region1516is drawn toward the central region of the breast milk extraction system and milk is extracted during the compression cycles. A disposable or reusable collection means (e.g.bag1515) is used to line the breast milk extraction system that includes the flange1500that will cover the breast around the nipple region1516where the bag1515slightly narrows around the nipple region1516providing room for the nipple. Furthermore, a collection region1517in the bag1515allows for the collection of expressed milk. The inlet or opening in the collection bag contacts the lips or distal region of the jaw portions. The remainder of the collection bad is fed through the opening formed by the jaws and into the frame.

[0101] shows, in side view1600additional elements of the breast milk extraction system shown in, when applied to a woman’s breast, in accordance with parts of the present disclosure. A plurality of inflatable chambers1618is shown that wraps around the upper and lower mandible components (not shown) and provides a compression force on the region at the bottom of the nipple region1516nearest the breast when the plurality of inflatable chambers1618is expanded. Likewise, when the plurality of inflatable chambers1618is shrunk, by removal of the gas or liquid used to expand it, the pressure on the lower nipple region is removed. In a similar a plurality of inflatable chambers1619can be built into the synthetic tongue (not shown) so that the synthetic tongue can expand at the proper time applying pressure to the nipple where such compression aids in the drawing and expressing of the milk.

[0102] The synthetic tongue preferably is controlled to move in unison with the lower jaw portion to mimic a suckling baby.

[0103] For the plurality of chambers (e.g.plurality of chambers1618, plurality of chambers1619, etc.) their inflation or relaxation material (gas or liquid) is provided via a plurality of tubular channels1620. The filling media provided to control the expansion of the the plurality of chambers (e.g.plurality of chambers1618, plurality of chambers1619, etc.) is controlled by distribution box1621coupled to a pump1622and a reservoir1623of the filling media. Inthere are two of the distribution, pumping and reservoirs, which is done to reduce the complexity of the drawing. However, a single distribution, pumping and reservoir may also be used. In addition, the timing of the pumping process may be mechanically or electronically provided to the structure of the present disclosure. In addition, the surfaces and filling media in the preferred embodiment may utilize electrical heating to produce the feeling on the breast and nipple of the mother that matches that of and infant’s mouth.

[0104] shows, in front perspective view, a mold cast1700for a jaw mechanism, made to replicate the general shape and size of an infant's jaw. Similarly,shows, in side perspective view, the mold cast1700for a jaw mechanism, in accordance with parts of the present disclosure.

[0105] Turning to, which shows, in isometric view, a pivot and cam mechanism1800that can be used to control the motion of jaw mechanism of a breast milk extraction system in accordance with parts of the present disclosure. The pivot and cam mechanism1800features a fixed base and fixed cam path which follows an upward curve shape to allow for the thrusting motion of the lower jaw232. A rigid bar is slotted through the lower jaw and tracks smoothly within the cam track to replicate the biomimetic thrusting motion. The lower jaw assembly230including lower jaw232is also coupled to a fixed base (not shown) at a main pivot point (not shown) and a rear rotary input (not shown) to allow for swinging with a two-bar linkage.

[0106] shows, in isometric view, a four-bar linkage system1900that can be used to control the motion of jaw mechanism of a breast milk extraction system in accordance with parts of the present disclosure.is similar to, however, ina five-bar linkage mechanism is utilized.

[0107] shows, in isometric view, a dual servo mechanism2000that can be used to control the motion of jaw mechanism of a breast milk extraction system in accordance with parts of the present disclosure. The dual servo mechanism2000can allow for a thrusting motion that is driven by an actuating servo motor (not shown) that gives the lower jaw232a back-and-forth horizontal motion, between the retracted configuration ofand the extended configuration of. A swing servo (not shown) is fixed at the base of the design with a two-bar linkage which attaches to the proximal end of the lower jaw230to allow it to swing closed or open, with respect to the upper jaw. The lower jaw assembly230including lower jaw232is also coupled to the base at a main pivot point (not shown) to synchronize the movements of the thrusting servo and swing servo.

[0108] The breast milk extraction system can achieve biomimicry by replicating the natural suckling motion of an infant through a combination of cyclical motions involving thrusting, pulsation, massaging of the breast, etc. Unlike conventional pumps that rely solely on vacuum pressure, this design incorporates synthesized motion including nuzzling of the breasts to mimic the rhythmic latch-and-release behavior observed in breastfeeding. The soft, flexible material(s) used, including the cover and / or tongue, simulate the soft tissue response of a baby’s mouth, ensuring a more natural and comfortable experience for the user. Additionally, integrated feedback loops enhance milk expression by allowing the user to adjust the features of the breast milk extraction system including speed, positions, temperature, etc., further aligning the pump’s function with biological processes.

[0109] In some embodiments, the same / similar principles of biomimetic suckling can be applied to sexual wellness devices, particularly those designed for stimulation and therapeutic massage. By leveraging variable suckling / thrusting and dynamic pressure control, these devices can replicate natural physiological responses, enhancing user comfort and engagement. The soft, flexible materials used in the cover of the breast milk extraction system can be adapted to create ergonomic, body-responsive stimulation surfaces, ensuring a lifelike tactile experience. Furthermore, the integration of smart sensors allows for real-time feedback and customization, enabling users to adjust intensity and rhythm based on personal preference.

[0110] This cross-application of biomimetic engineering underscores the versatility of adaptive suckling and compression technologies, demonstrating their potential in both maternal care and intimate wellness.
