Many new mothers use breast pumps post-birth in order to achieve their personal milk feeding and expression goals. Breast pumps systems draw breast milk from a breast of a user and may be used to pump breast milk for later consumption by an infant, to stimulate lactation in users with low milk supply, or to relieve engorgement. Breast pumps may be manually operated, for example by squeezing a handle or operation of a foot pedal. Breast pumps may also be electrically driven by a drive unit.
On average, new mothers feed their infants more than 12 times per day, with newborn infants needing to be fed every two to three hours. Mothers may spend more than four hours each day breastfeeding, on average spending 20 minutes out of every two hours breastfeeding, interrupting work, social, and sleep schedules. The demands of breastfeeding and pumping require mothers to wake up throughout the night drastically decreasing the total hours of sleep per night a mother is able to achieve. Such sleep loss contributes to a number of conditions in women, such as mastitis and postpartum depression.

The present disclosure provides improved breast milk distribution systems, components thereof, and methods of use thereof. The present breast milk distribution systems are particularly advantageous for use in a series of breast pumping sessions without removal of a breast cup and/or without replacement of a reservoir in the breast milk distribution system.
Breast Milk Distribution System
The United States Food and Drug Administration (FDA) advises against mixing freshly expressed breast milk with already cooled or frozen milk as it can rewarm the older stored milk. The FDA also advises against storing milk at room temperature for more than 4 hours. Thus, it is advantageous to have a breast milk distribution system (1) that can provide for multiple breast pumping sessions without the removal of a breast cup (2), as well as divert milk to different reservoirs (3) from a plurality of breast pumping sessions.
The present disclosure provides a milk distribution system, e.g., a breast milk distribution system (1). The breast milk distribution system is advantageous in that it may facilitate repeated breast pumping without the removal of a breast cup (2) from a breast and/or without the replacement of a reservoir (3) from a breast milk distribution system (1). The presently disclosed breast milk distribution system (1) is advantageous in that it may be used with a variety of breast cups and breast pump systems.
In some embodiments, the breast milk distribution system (1) can include a manifold (6) comprising an inlet (8) and a plurality of outlets (13), e.g., as shown in
Alternatively, the manifold (6) can include an inlet (8) and an outlet (13), in which the outlet (13) is configured to provide fluidic communication to a plurality of reservoirs (3). In some embodiments, the milk distribution system (1) includes a manifold (6) configured to be in fluidic communication with a breast cup (2), wherein the manifold (6) includes an inlet (8) and an outlet (13) configured to move from a first position to a second position, e.g., as shown in
In some embodiments, the breast milk distribution system (1) includes a plurality of reservoirs (3), e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20. In some embodiments, the breast milk distribution system (1) can include a manifold (6) comprising an inlet (8) and a plurality of outlets (13), wherein each outlet (13) comprises a valve (24); and a plurality of reservoirs (3), wherein each of the plurality of reservoirs (3) is in fluidic communication with a different outlet (13).
In some embodiments, the breast milk distribution system (1) is configured to distribute milk from a plurality of breast pumping sessions based on a pre-programmed pumping schedule input by a user. In some embodiments, milk from a first pre-programmed breast pumping session of the pre-programmed pumping schedule is transported to a first reservoir (3), and milk from a second pre-programmed breast pumping session of the pre-programmed pumping schedule is transported to a second reservoir (3). Different pumping sessions may be spaced apart by time, e.g., 3-4 hours.
Pumping milk to the milk distribution system may occur by the action of the diaphragm. Other pumping mechanisms may also be employed, including providing positive pressure breast cup, e.g., by forced air or providing negative pressure to a fluid conduit between the breast cup and a reservoir. Negative pressure may be employed by a peristaltic pump or by air being pulled into the fluid conduit. These may also act to flush the conduit after a pumping session or after a set number of pumping session. For example, a flush line may connect to the fluid conduit, with both the flush line and the fluid conduit having one directional valves to prevent back flow. Negative pressure may be applied by reducing pressure in a reservoir, and a vent may be present to release pressure when desired, e.g.,
Breast milk distribution systems may also include a pressure source, a reservoir enclosure, one or more fluid conduits, and/or a breast cup.
The breast milk distribution system may be employed with any suitable breast cup that can be in fluidic communication with the system, e.g., via a fluidic conduit. As is known in the art, breast cups may include a breast shield component that is designed to contact the breast and surround the nipple. Breast cups may also include a housing to surround the breast shield. The breast cup may be actuated manually or by automation, e.g., by pressure cycles from a pump or other pressure source. The system is advantageous for automated pumping as it allows for the breast cup to stay in place for multiple sessions, while allowing milk from separate sessions to be stored separately.
The breast milk distribution system may be configured such that the user may roll during rest and/or sleep. Currently available breast milk distribution systems are not designed to be utilized while resting, reclining, or sleeping.

In some embodiments, pressure applied to the breast cup (2) changes gradually. In some embodiments, pressure applied to the breast cup (2) changes at different rates, e.g., in a first cycle the pressure applied to the breast cup (2) changes over about 0.1 seconds to about 120 seconds (e.g., about 1 second), and in a second cycle the pressure applied to the breast cup (2) changes over about 0.1 seconds to about 120 seconds (e.g., about 5 seconds).
Pressure within the breast cup (2) can provide a pulsating or massaging sensation. In some embodiments, the speed and pressure of the pulsation or massage may be selected by the user. In some embodiments, alternating pressure mimics the action of suckling.
Additional Elements
In some embodiments, the breast milk distribution system (1) includes a pressure outlet. The pressure outlet may or may not include a valve (24). In some embodiments, each pressure outlet includes a valve (24). In some embodiments, the pressure outlet is a breather tube. In some embodiments, the pressure outlet is an orifice, e.g., the reservoir (3) or the lid of the reservoir (3) may include an orifice. In some embodiments, the breast milk distribution system (1) includes a pressure outlet in fluidic communication with each reservoir (3).
In some embodiments, the reservoir (3) includes a pressure indicator, e.g., a flexible membrane. A pressure indicator, e.g., a flexible membrane, may be advantageous in indicating if there is negative or positive pressure within the reservoir (3). Negative pressure may be the result of hot milk being cooled when the reservoir (3) is closed to the ambient atmosphere and/or the breast milk distribution system (1).
In some embodiments, the breast milk distribution system (1) includes a waste reservoir. In some embodiments, following a breast pumping session, the breast milk distribution system (1) may flush the system with a cleaning fluid, wherein the cleaning fluid is transported to a waste reservoir. In some embodiments, the cleaning fluid is water. In some embodiments, the cleaning fluid is air. In some embodiments, the breast milk distribution system (1) is configured to be flushed with a pressure source, e.g., positive pressure source or a negative pressure source, e.g., a vacuum pump.
In some embodiments, the breast milk distribution system (1) may include an anti-bacterial coating, e.g., in the reservoir (3) or the fluid conduits (5).
The breast milk distribution system (1) may include a power source (12). The power source (12) may be a battery and/or an AC power source. The power source (12) may be electrically connected to the control unit and the pumping mechanism.
The breast milk distribution system (1) may include a display. The display may be disposed on the pump housing (7) or reservoir enclosure (4). The display may be a screen. In some embodiments, the screen is a touchscreen.
The breast milk distribution system (1) may include a timer. The drive unit (11) and/or control unit may include the timer. The timer may be disposed in the pump housing (7) or reservoir enclosure (4).
The breast milk distribution system (1) may include an alarm. The alarm may be disposed in the pump housing (7) or reservoir enclosure (4). The alarm may be a light, a vibration element, or a sound element. The alarm may be configured to sound in the event of an error (e.g., the pumping system is improperly assembled), the ending of a pumping session, a temperature increase in the milk in the reservoir (3), a full reservoir (3), and/or the start of an upcoming preprogrammed pumping session.
The breast milk distribution system (1) may include a power switch (14) or button. The power switch (14) or button may enable a user to power on or off the breast milk distribution system (1). The power switch (14) or button may be disposed on the outside of the pump housing (7). Alternatively, or in addition, the power switch (14) or button may be disposed on the reservoir enclosure (4). However, in some embodiments, the user may power on or off the breast milk distribution system (1) remotely, such as through an application on an external computer, e.g., a mobile device.
Breast Milk Distribution System Control
The breast milk distribution system may include controls that are operable by a user to select or modify at least one of: pumping program or mode, frequency of pumping cycle, maximum suction pressure achieved during a pumping cycle, latch suction pressure achieved during the pumping cycle, pumping force, pumping session time, and distribution of milk to reservoirs (3). The controls may be present on the surface of the pump housing (7) or reservoir enclosure (4), e.g., on the display. Alternatively, or in addition, the controls may be present in an application on an external computer, e.g., a mobile device. Alternatively, neither the pump housing (7) or reservoir enclosure (4) includes controls, and the breast milk distribution system (1) is solely controlled through an application on an external computer, e.g., a mobile device. Control of the breast milk distribution system through an application on an external computer is advantageous in that a user may control the device in any position.
In some embodiments, the breast milk distribution system can have a wait time set, e.g., through the display or an application on an external computer, such that the user has time to contact the breast cup (2) to their breast before the system begins pumping.
Control of the breast milk distribution system (1) may be customized. The customized pump functions include modifications to at least one of: maximum suction pressure level, latch suction pressure level, suction pressure waveform over a pumping cycle, phases of extraction or feeding times, rest times, heating temperatures and times, vibration frequency and duration, pumping session time, and distribution of milk to reservoirs (3). The user may input at least one pump program into the breast milk distribution system (1), e.g., through the display or application on an external computer. For example, the user may set the number of minutes that the breast milk distribution system (1) will run before shutting off automatically and/or the user may set a time for the breast milk distribution system (1) to engage during the night. Custom pump programming is advantageous in that user may control how long they pump for so that they may go about their daily activities, resting, or sleeping, without the worry that the pump will continue endlessly. In some embodiments, the pumping frequency may be programmed to slow down gradually during operation, e.g., towards the end of a preprogrammed pumping time.
Wireless
The control unit may be configured to send signals to and receive signals from an external computer, e.g., a mobile device.
The control unit may include a transmission element, e.g., a wireless transmission element, and receiver element for wirelessly sending signal to and receiving signals from the external computer. In some embodiments, the transmission element is a BLUETOOTH® transmission element.
The external computer may include a processor and instructions, which when executed, cause the processor to customize pump functions and send customized pump functions to the control unit. In some embodiments, the custom pump functions are based on the signals received from the control unit, such as measurements taken by sensors. In some embodiments, the user is able to program different custom pump programs, e.g., a daytime program and a nighttime program.
The external computer may include a processor and Instructions, which when executed, cause the processor to calculate volume of milk extracted and track expression efficiency and monitor it over time. In some embodiments, the calculation of milk extracted, and expression efficiency are based on signals received from the control unit, such as measurements taken by the sensors.
The external computer may include a processor and instructions, which when executed, cause the processor to transport milk from a breast pumping session to a reservoir, including transporting milk from a first breast pumping session to a first reservoir, and milk from a second breast pumping session to a second reservoir.
The external computer may include a processor and instructions, which when executed, cause the processor to track of inventory of previous pumping sessions, including tracking at least one of dates of the previous pumping sessions, volumes pumped in the previous pumping sessions, and specific tracking numbers for specific milk collection containers into which milk has been pumped in the previous pumping sessions.
The external computer may include a processor and instructions, which when executed, cause the processor to one or more of monitor remaining battery power of the battery and output a warning when the battery reaches a predetermined low level of charge.
The external computer may include a processor and instructions, which when executed, cause the processor to display in the application screen or on display of the breast milk distribution system (1) the time left in the pumping session, measurements taken by the at least one sensor, and/or one or more photos of the user's choosing on the display.
Methods of Use
The present disclosure provides improved methods of collecting and distributing pumped breast milk.
The present disclosure provides a method of breast milk distribution by: (i) providing a breast milk distribution system of the disclosure; (ii) pumping milk from a human breast using breast cup; and (iii) applying pressure to move milk from the breast cup to the reservoir (3).
In some embodiments, the method includes transporting milk through the first fluid conduit. In some embodiments, the method includes transporting milk through the one directional valve. In some embodiments, the method includes applying pressure to the manifold (6) with a pressure source to transport milk to a reservoir (3). Thus, in some embodiments, the pressure source, or a second pressure source, can be in fluidic communication with the manifold (6). In some embodiments, a positive pressure source is in fluidic communication with the manifold (6) and transports milk to a reservoir (3). In some embodiments, the method includes applying a negative pressure source to the breast cup at the end of the pumping session. In this embodiment, the negative pressure transports any residual milk from the breast cup and fluid conduit (5) into the reservoir (3). In some embodiments, the negative pressure source is a peristaltic pump, e.g., on a first conduit or downstream component connected thereto. Positive pressure may also be introduced into the breast cup, e.g., via a separate inlet, to aid in transport of milk or cleaning. The clearing of milk from the fluid conduit and/or breast cup may occur only once at the end of a breast pumping cycle.
In some embodiments, the method includes providing a cleaning fluid to the breast milk distribution system (1). In some embodiments, the method includes transporting a cleaning fluid from the breast cup (2) to a waste reservoir (3). In some embodiments, the cleaning fluid is transported through the manifold (6). In some embodiments, the cleaning fluid is water. In some embodiments, the method includes pumping milk from the human breast twice, in which there is at least 30 minutes from a first breast pumping session to a second breast pumping session. In some embodiments, the method includes pumping milk from the human breast 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 times. In some embodiments, the method includes pumping milk from the human breast a plurality of times (e.g., from 2 to 3 times, from 2 to 4 times, from 2 to 5 times, from 2 to 6 times, from 2 to 10 times, from 3 to 4 times, from 3 to 5 times, from 3 to 10 times, from 4 to 5 times, from 4 to 6 times, or from 5 to 10 times).
In some embodiments, the time between one breast pumping session and another breast pumping session (e.g., between a first breast pumping session and a second breast pumping session, a second breast pumping session and a third breast pumping session, a third breast pumping session and a fourth breast pumping session, etc.) is from about 30 minutes to about 240 minutes (e.g., about 30 minutes to about 45 minutes, about 30 minutes to about 60 minutes, about 30 minutes to about 90 minutes, about 30 minutes to about 120 minutes, about 30 minutes to about 180 minutes, about 45 minutes to about 60 minutes, about 45 minutes to about 90 minutes, about 45 minutes to about 120 minutes, about 60 minutes to about 90 minutes, about 60 minutes to about 120 minutes, about 50 minutes to about 180 minutes, about 60 minutes to about 210 minutes, about 90 minutes to about 120 minutes, about 90 minutes to about 180 minutes, about 90 minutes to about 210 minutes, about 90 minutes to about 240 minutes, about 120 minutes to about 180 minutes, about 120 minutes to about 210 minutes, about 120 minutes to about 240 minutes, about 180 minutes to about 210 minutes, about 180 minutes to about 240 minutes, about 210 minutes to about 240 minutes, about 30 minutes, about 45 minutes, about 60 minutes, about 85 minutes, about 90 minutes, about 105 minutes, about 120 minutes, about 135 minutes, about 150 minutes, about 165 minutes, about 180 minutes, about 195 minutes, about 210 minutes, about 225 minutes, or about 240 minutes). In some embodiments, the breast milk distribution system (1) may enter a waiting phase between breast pumping sessions where the breast cup (2) and/or manifold (6) is not in fluidic communication with any reservoir (3). In some embodiments, following a breast pumping session, the breast milk distribution system (1) places the breast cup (2) and/or manifold (6) in fluidic communication with a second reservoir (3). The second reservoir (3) may be empty.
In some embodiments, milk from the first breast pumping session is transported to a first reservoir, and milk from the second breast pumping session is transported to a second reservoir. Likewise, milk from a third, fourth, fifth, sixth, seventh, eighth, ninth, or tenth breast pumping session may be transported into a third, fourth, fifth, sixth, seventh, eighth, ninth, or tenth reservoir, respectively. In some embodiments, the method includes removing fluidic communication between the breast cup (2) and all of the reservoirs (3) between breast pumping sessions. In some embodiments, a plurality of valves is closed to remove fluidic communication between the breast cup (2) and all of the reservoirs (3). Once full, a reservoir may be removed and replaced with an empty reservoir.
The breast milk distribution system (1) is advantageous in that the user may be able to breast pump a plurality of times following a one-time assembly. Prior to the first use, the user may secure the breast cup to a breast. Then, in some embodiments, the user does not need to remove the breast cup (2) between a plurality of breast pumping sessions, e.g., two, three, four, five, six, seven, eight, nine, or ten breast pumping sessions. The breast milk distribution system (1) is further advantageous in that the user may be able to breast pump in a reclined position. As the breast milk distribution system (1) may be used for an extended time, e.g., overnight, the user's ability to place the wearable component on one time, yet still use the pump several times without removal of the garment will allow for uninterrupted sleep during at least one breast pumping session. A pre-programmed pumping schedule may initiate the breast milk distribution system (1) at least once, e.g., two, three, four, five, six, seven, eight, nine, ten times, etc. In some embodiments, the breast milk distribution system (1) can distinguish between pumping sessions based on the pre-programmed breast pumping schedule. For example, on the initiation of a new breast pumping session, the breast milk distribution system (1) can divert the milk flow via a manifold (6) to an empty reservoir (3).
In some embodiments, the method includes pumping milk from the human breast to induce milk from a first breast pumping session to flow from a nipple to the manifold via the breast cup (2); providing fluidic communication between the inlet (8) of the manifold (6) and a first reservoir (3) to allow milk from the first breast pumping session to flow into the first reservoir (3); removing fluidic communication between the inlet (8) of the manifold (6) and the first fluid reservoir (3); pumping the human breast to induce milk from a second breast pumping session to flow from the nipple to the manifold (6) via the breast cup (2); and providing fluidic communication between the inlet (8) of the manifold (6) and a second reservoir (3) to allow milk from the second breast pumping session to flow into the second reservoir (3). In some embodiments, the time between first and second pumping sessions is from about 30 minutes to about 240 minutes (e.g., about 30 minutes to about 45 minutes, about 30 minutes to about 60 minutes, about 30 minutes to about 90 minutes, about 30 minutes to about 120 minutes, about 30 minutes to about 180 minutes, about 45 minutes to about 60 minutes, about 45 minutes to about 90 minutes, about 45 minutes to about 120 minutes, about 60 minutes to about 90 minutes, about 60 minutes to about 120 minutes, about 50 minutes to about 180 minutes, about 60 minutes to about 210 minutes, about 90 minutes to about 120 minutes, about 90 minutes to about 180 minutes, about 90 minutes to about 210 minutes, about 90 minutes to about 240 minutes, about 120 minutes to about 180 minutes, about 120 minutes to about 210 minutes, about 120 minutes to about 240 minutes, about 180 minutes to about 210 minutes, about 180 minutes to about 240 minutes, about 210 minutes to about 240 minutes, about 30 minutes, about 45 minutes, about 60 minutes, about 85 minutes, about 90 minutes, about 105 minutes, about 120 minutes, about 135 minutes, about 150 minutes, about 165 minutes, about 180 minutes, about 195 minutes, about 210 minutes, about 225 minutes, or about 240 minutes).
In some embodiments, the method further includes removing fluidic communication between the inlet (8) of the manifold (6) and the second fluid reservoir (3); and providing fluidic communication between the inlet (8) of the manifold (6) and a third reservoir (3); and pumping the human breast to induce milk from a third breast pumping session to flow from the nipple to the manifold (6) via the breast cup (2). In some embodiments, the time between second and third pumping sessions is from 30 minutes to 240 minutes (e.g., about 30 minutes to about 45 minutes, about 30 minutes to about 60 minutes, about minutes to about 90 minutes, about 30 minutes to about 120 minutes, about 30 minutes to about 180 minutes, about 45 minutes to about 60 minutes, about 45 minutes to about 90 minutes, about 45 minutes to about 120 minutes, about 60 minutes to about 90 minutes, about 60 minutes to about 120 minutes, about 50 minutes to about 180 minutes, about 60 minutes to about 210 minutes, about 90 minutes to about 120 minutes, about 90 minutes to about 180 minutes, about 90 minutes to about 210 minutes, about 90 minutes to about 240 minutes, about 120 minutes to about 180 minutes, about 120 minutes to about 210 minutes, about 120 minutes to about 240 minutes, about 180 minutes to about 210 minutes, about 180 minutes to about 240 minutes, about 210 minutes to about 240 minutes, about 30 minutes, about 45 minutes, about 60 minutes, about 85 minutes, about 90 minutes, about 105 minutes, about 120 minutes, about 135 minutes, about 150 minutes, about 165 minutes, about 180 minutes, about 195 minutes, about 210 minutes, about 225 minutes, or about 240 minutes).
In some embodiments, the method further includes providing fluidic communication between (i) the inlet (8) of the manifold (6) and (ii) the first reservoir (3), the second reservoir (3), or the third fluid reservoir (3) by moving, e.g., rotating, the movable, e.g., rotating, member. In some embodiments, the method further includes removing fluidic communication between (i) the inlet of the manifold and (ii) the first reservoir (3), the second reservoir (3), or the third fluid reservoir (3) by moving, e.g., rotating, the movable, e.g., rotating, member. In some embodiments, the movable, e.g., rotating, member moves clockwise with respect to the stationary member. In some embodiments, the movable, e.g., rotating, member moves counterclockwise with respect to the stationary member.
In some embodiments, the method further includes providing fluidic communication between (i) the inlet of the manifold (6) and (ii) the first reservoir (3), the second reservoir (3), or the third fluid reservoir (3) by opening the valve to the inlet of the first reservoir (3), the second reservoir (3), or the third fluid reservoir (3).
