Patent Application
20200093701
Colostrum is the first nutritional liquid that comes out of the breast during lactation and is a very important food substance for development of a healthy newborn. This highly nutritional material is also packed with antibodies and other immune enhancing substances. Colostrum is produced at a very slow rate—a few milliliters per hour—and generally requires some form of pumping and/or hand expression to express it from the breast. Additionally, breast milk sometimes is expressed in small volumes, especially towards the beginning and end of the expression time. Thus, although colostrum is critical for early newborn nutrition, it is only produced in very small quantities and can be difficult to collect.
Currently, colostrum is typically collected using a funnel, also called a breast flange or shield, which connects to a large collection container (such as a milk bottle), typically via a one way valve. Alternatively, hand expression is performed on the breast, and colostrum is collected in a spoon, small cup, or small vial. These collection containers (bottle, spoon, etc.) require transfer to another container—typically a small syringe—for administering small volumes of colostrum to the newborn. This transfer of material from collection container to administration container leads to at least some amount of wasted colostrum, despite the fact that the total collected amount is very small to begin with. The inherent difficulty in collecting and administering colostrum leads many nursing mothers to become discouraged and not collect any colostrum at all. This difficulty also sometimes leads to mothers giving up on breast feeding altogether.
Therefore, it would be advantageous to have improved devices, systems and methods for collecting and administering colostrum. Ideally, such devices, systems and methods would also be applicable for collecting and administering breast milk. Also ideally, such devices, systems and methods would be relatively easy to use and would eliminate the step of transferring colostrum and/or breast milk from a collection container to an administration device. The embodiments described below address at least some of these objectives.
The disclosure herein describes an adapter, a system, and a method for collecting colostrum and/or breast milk from a breast of a female human or animal. In some embodiments, the adapter, system and/or method may be used for both collection and administration of colostrum and/or breast milk. Many of the embodiments and features described in this application are designed specifically for collection and delivery of colostrum, and thus many of the descriptions below focus on that use. However, many, if not all, of these embodiments and features may also be used for collection and delivery of breast milk. Although the below description will not always repeat the statement that the various embodiments may be used for colostrum, breast milk or both, the scope of the invention covers any and all such uses.
In general, the adapter is compatible with a funnel, breast flange/shield, and/or funnel with a flange or connector, such that the connector can facilitate capture and dispensing of breast milk and/or colostrum from a syringe or other compatible collection/administration device. The container, catchment device(s), valves, and connectors may optionally be lubricated, to facilitate the movement of breast fluids, such as colostrum and/or breast milk, into a catchment area. The catchment area collects the fluid and allows it to easily be drawn into, or flow into, a syringe via a connector.
The connector may attach to the front or the rear of a cylindrical syringe with a plunger for expelling material post-capture and/or a plunger for moving to suck or pull material into the barrel of the syringe during capture. The container that is coupled with the adapter to collect colostrum and/or milk does not have to be a syringe, but may alternatively be any container that can connect via a connection means to the funnel adapter and then expel the material from the same container. This may include, but is not limited to, an attached bag, a vacuutainer, a bottle, a rectangular or odd shaped catchment container, a compressible container, a rollable container, or any other container that can connect to a capture funnel or comprise a capture funnel that also may serve to deliver the material to the infant. A “container” may also be referred to herein as a “fluid collection device,” which has a synonymous meaning for the purposes of this application. Thus, a fluid collection device may be any of the types of containers listed above or any other suitable container for use with the adapter and/or system described herein for collection of colostrum and/or milk.
Lubricant or frictional material on the surface of the connectors may serve to facilitate connection to the syringe and or the funnel section or they may serve to allow for rapid flow with less adhesion of the breast product on the wall of the container. This lubricant or frictional material may or may not increase or decrease friction as desired in different regions. Additionally, it may be pressure sensitive through shear thickening or shear thinning. It may be silicone, nano-printed with interspaced fluid, or other lubricious or frictionous coating. To increase friction, a sand or imprinted/dimpled area may be used, if desired in connector regions.
The connector for the syringe or other container to the funnel and/or an adapter that fits both a funnel and a container, may comprise a Luer connector, press fit connector, tapered section, screw thread, tube attachment, or other means of attaching a syringe or other container with an adapter or funnel that may serve to capture and dispense colostrum.
The funnel and/or adapter to a funnel may also comprise a catchment reservoir to accumulate droplets of material to or near the connector. The catchment reservoir and surrounding area may optionally be coated with a lubricious material to facilitate movement of material or cause less adhesion to the wall. The catchment area guides the flow of material to the connector when the adapter or the funnel is in the appropriate configuration. Additionally, a block or guide may serve to facilitate flow into the catchment reservoir, while also including an opening to create a suction force. This opening may be in any area of the block, but one ideal location may in the top half of the block, away from the catchment reservoir side.
Additionally, an adapter or a funnel may also comprise a system that has two catchment containers of different sizes. In one such example the front container comprising a syringe may be smaller than a back container comprising a bottle or catchment jar. The syringe in the front container may serve to extract small volumes of material where the catchment jar in the back may serve to capture large volumes of materials. The small volume container may be arranged such that it can catch material stopped by a block, while the large container would be filled via the hole in the block that allows for flow into the larger container. There may or may not be a one way valve that helps prevent reverse flow from the larger container and/or flow into the vacuum port in the attachment area of the larger container. This vacuum port in the larger container also comprises vacuum through the hole in the block that is used as a flow-through area to fill the larger container or not used as a flow-through area when the smaller container is desired to be filled. The funnel may be rotated, or a rotational mechanism within the adapter may be used, if it is desired to keep the funnel stationary if the user wants to switch from extracting small volumes with the syringe to large volumes with the large container. Additionally, the large container could also include attachment means for a syringe or suction port to be used in the catchment area of the funnel or the adapter.
Also disclosed is a method for capture and dispensing of colostrum or other milk product. A funnel with a connector to a small container or an adapter to an existing funnel with a connector is used to capture and dispense milk product to an infant. The mechanism of capture is through a funnel, which allows milk product to flow into a catchment area or catchment reservoir. This catchment area or reservoir may or may not be formed by a depression in the side or by the function of a block in the internal section of the opening of the funnel that, when placed on a side orientation, forms a catchment area to collect fluid or viscous material. The block may also have an opening opposite the catchment area, such that air flow or vacuum may facilitate the movement of material out of a breast/nipple. The catchment of the material also comprises a connector that is attachable to a delivery device such as but not limited to a syringe. This delivery device may actively suck up material from the catchment area or may have an opening large enough such that flow from the catchment area into the delivery device can be accomplished with air venting out one or more openings, not excluding the opening forming the connection with the catchment area. The delivery device, once containing captured material, is used to deliver milk product after detachment from the adapter or funnel with the connector. After detachment, the delivery device is used with a feeding tube or without a feeding tube to administer the milk or colostrum material to the infant or newborn of any species, including but not limited to humans, horses, dogs, cats, hamsters, whales, or any other type of mammal.

In some embodiments, the collection device comprises a syringe, and moving the colostrum from the catchment area into the collection device comprises retracting a plunger of the syringe. In some embodiments, connecting the adapter with a source of suction comprises connecting the second end of the adapter to a breast pump system. Some embodiments may further include collecting milk from the breast through an additional side port in the adapter, into an additional collecting device coupled with the additional side port. Such a method may also further include switching a valve from a first position, for collecting colostrum, to a second position, for collecting milk. The method may also further include preventing the colostrum from passing through the second end of the adapter with a blocking member disposed in the adapter between the side port and the second end.
In another aspect of the disclosure, a method for collecting colostrum from a breast may involve: connecting a small diameter end of a funnel device with a suction source; connecting a collection device with a side port of the funnel device; contacting an large diameter end of the funnel device with the breast; activating the suction source to generate suction force through the funnel device; collecting colostrum in a catchment area of the funnel device; and moving the colostrum from the catchment area into the collection device.
In some embodiments, connecting the funnel device with a source of suction comprises connecting the small diameter end of the funnel device to a breast pump system. Some embodiments may further include collecting milk from the breast through an additional side port in the funnel device or the suction source, into an additional collecting device coupled with the additional side port. Such embodiments may also include switching a valve from a first position, for collecting colostrum, to a second position, for collecting milk. Some embodiments may also include preventing the colostrum from passing through the small diameter end of the funnel device with a blocking member disposed in the funnel device between the side port and the second end.
In another aspect of the disclosure, an adapter for use in a system for collecting colostrum and/or breast milk may include: a body having a predominantly cylindrical shape; a first open end of the body for connecting to a funnel device; a second open end of the body for connecting to a source of suction; a blocking member inside the body, between the first open end and the second open end, for preventing colostrum from passing from the first open end through the second open end; an aperture in the blocking member to allow suction force applied at the second open end to generate suction at the first open end; a reservoir extending off of a side of the body, between the first open end and the blocking member, for containing the colostrum and/or breast milk, wherein the reservoir has a proximal end located at a junction of the reservoir with the side of the body and a distal end; and a port disposed on the distal end of the reservoir for connecting the adapter to a fluid collection device.
In some embodiments, the adaptor may have a one-piece construction. In some embodiments, the first open end and the second open end may have different inner diameters. In some embodiments, the blocking member may be a wall, and the aperture may be a hole through the wall. In some embodiments, the hole is located closer to an opposite side of the body of the adapter than to the side of the adapter off of which the reservoir extends. In some embodiments, the reservoir further includes fluid level markings for measuring an amount of the colostrum and/or breast milk in the reservoir.
In some embodiments, the first open end has an inner diameter sized to fit a narrow end of the funnel device within the first open end, and the second open end has an outer diameter sized to fit a connecting end of the source of suction over the second open end. In some embodiments, the fluid collection device is a syringe, and the port is configured to attached to one end of the syringe. In various embodiments, the funnel device may be any suitable funnel or breast shield.
In another aspect of the disclosure, a method for collecting colostrum from a breast may involve: receiving colostrum expressed from the breast into an open end of a funnel device that is connected at an opposite end to a first end of an adapter; applying a first suction force at a second end of the adapter, using a suction source connector coupled with the second end of the adapter, where the first suction force is transmitted through an aperture in a blocking member inside the adapter to facilitate movement of the colostrum through the funnel and into the adapter; using the wall in the adapter to prevent the colostrum from passing through the second end of the adapter and direct the colostrum into a reservoir extending off of a side of the adapter; allowing the colostrum to collect in the reservoir; applying a second suction force to a port on the reservoir, using a colostrum collection device attached to the port; and allowing the colostrum to pass out of the reservoir and into the colostrum collection device, in response to the second suction force.
In some embodiments, the funnel device is a breast shield, and the method may further include contacting the open end of the breast shield with the breast before applying the first suction force. Some embodiments may further involve measuring a fluid level of the colostrum in the reservoir by viewing the colostrum and a fluid level marker on a side of the reservoir. Some embodiments may further involve removing the collection device from the port, after the colostrum has passed into the collection device, and delivering the colostrum directly to a newborn from the collection device, without passing the colostrum into any additional device. In some embodiments, applying the first suction force involves turning on a breast pump device coupled with the second end of the adapter. In some embodiments, the collection device is a syringe, and applying the second suction force involves retracting a plunger of the syringe.
In another aspect of the disclosure, an adapter system for facilitating collection of colostrum from a breast may include an adapter, a removable reservoir and a hand-expression funnel. The adapter may include a first open end for connecting to a breast shield of a breast pump system, a second open end for connecting to a breast pump connector of the breast pump system, and a third open end, disposed between the first and second open ends, for allowing the colostrum to pass out of the adapter, The removable reservoir may include a wide end for removably attaching to the third open end and a narrow end for attaching to a colostrum delivery device.

The blocking member, for example, may include a wall, and the aperture may include a hole through the wall. In some embodiments, the hole is located closer to a top of the adapter than to a bottom of the adapter. In some embodiments, the first open end has a first inner diameter that is larger than a second inner diameter of the second open end.
The removable reservoir and/or the hand-expression funnel may each optionally include fluid level markings for measuring an amount of the colostrum. In some embodiments, the colostrum delivery device is a syringe. The narrow end of the removable reservoir may optionally include threads on its inner surface for coupling with outer threads on the syringe. The wide end of the removable reservoir may also optionally include threads on its inner surface for coupling with outer threads on the third open end of the adapter. The narrow end of the hand-expression funnel may also include threads on its inner surface for coupling with outer threads on the syringe.
The adapter system may include any number of components. For example, in one embodiment, the system includes a least one additional adapter and at least one additional removable reservoir, to allow a woman to breast pump both breasts simultaneously.
In another aspect of the disclosure, a method for collecting colostrum from a breast and delivering the colostrum to a newborn may involve: attaching an adapter with a removable reservoir to a breast pump shield at one end and a breast pump connector at an opposite end; attaching the removable reservoir with a syringe; expressing colostrum from the breast, into the removable reservoir; drawing the colostrum into the syringe by pulling back a plunger of the syringe; detaching the syringe from the removable reservoir; and delivering the colostrum to the newborn directly from the syringe.

The method may also optionally include measuring a fluid level of the colostrum in the funnel by viewing the colostrum and a fluid level marker on a side of the funnel. In some embodiments, after the detaching step and before the delivering step, the method may involve: attaching the syringe to a funnel; hand-expressing colostrum from the breast into a funnel; drawing the colostrum into the syringe by pulling back the plunger of the syringe; and detaching the syringe from the funnel.
These and other aspects and embodiments are described in further detail below, in relation to the attached drawing figures.
The embodiments described below are generally designed to facilitate collection and delivery of colostrum from a female breast. In some or all embodiments, the systems and devices described herein may also be used to collect and/or deliver breast milk. However, many or all of the embodiments may include features, such as reservoirs, receptacles, funnels, or the like, which are configured primarily for colostrum. For example, these features may be sized in such a way as to be specifically beneficial for the very small volumes of colostrum produced by the breast. In any event, whether a system is referred to as a “colostrum collection system” or a “colostrum and milk collection system,” any or all embodiments may be used, or adapted for use, for facilitating collection and/or delivery of colostrum and/or breast milk.
All figures either depict components in isolation or with breast pump accessory attachments or funnels, for use with a vacuum style breast milk pump that is hand powered or machine powered. The system is operable with suction and attachment to a breast to express the milk or colostrum through a funnel contacted to the breast. Embodiments allow for the capture of colostrum or milk into a collection device, which is then detached from the remainder of the system in order to deliver the milk or colostrum to the newborn, infant, or baby. In various exemplary embodiments, the components of a device or system may be press fit together, glide, screw in, or otherwise attach. In addition, in some embodiments, some components may rotate or glide and experience varying degrees of frictional resistance.
In use, breast milk and/or colostrum is expressed into wide end 101 of funnel 100. Suction force may be applied at narrow end 110 of funnel 100, and such force will pass through aperture 104, to help drawing milk and/or colostrum through wide end 101. Block 102 helps to block the milk and/or colostrum from passing through narrow end 110 and instead directs the milk and/or colostrum into catchment area 107 and thus through port 108. Trough 106 may also assist in directing milk and/or colostrum toward port 108. A syringe or other collection/delivery device (not shown) may then be used to draw the milk and/or colostrum through port 108 into the device, so that it can be delivered to a newborn. Port 108 may have any suitable configuration for connection to a collection/delivery device, such as but not limited to a luer connector, screw/threaded connector, press fit connector, or a combination thereof, to provide multi-connector functionality to work with multiple collection/delivery devices.
In use, colostrum (or alternatively breast milk) may be expressed into wide end 402 of funnel 401. Suction applied through system 400 via suction connection 412 and aperture 305 in adapter 301 (not visible in
In various embodiments, system 400 may be provided as only a subset of the devices depicted in
As illustrated in
Syringe 420 (or “collection/delivery device”) may be used to collect small quantities of liquid and/or more viscous liquid, such as but not limited to colostrum, and/or it may be used to periodically sample small quantities from the flow stream into the larger container. In various embodiments, any suitable size of syringe 420 may be used as a collection/delivery device. Also, as mentioned above, other types of collection/delivery devices may alternatively be used.

In the illustrated embodiment, system 800 includes an adapter 802, a removable reservoir 810 and a hand-expression funnel 816. In some embodiments, system 800 may be provided with two adapters 802, two reservoirs 810 and one funnel 816, to allow the woman to double pump (i.e., express colostrum from both breasts at the same time with two breast pump shields). Alternative embodiments of system 800 may include different numbers and/or combinations of components, different sizes and shapes of adapter 802, reservoir 810 and/or funnel 816, and/or the like. Adapter 802, in this embodiment, is a generally T-shaped adapter 802, with three open ends: a funnel connecting end 804, a breast pump connecting end 806 and a dispensing end 808. The interior portion of adapter 802, which is described in more detail in relation to
Removable reservoir 810 has a wide end 811 for connecting with dispensing end 808 of adapter 802, a narrow end 814 for connecting with syringe 420, and multiple level indicators 812 to help a user determine how much colostrum resides within reservoir 810. Funnel 816 includes a wide end 817 for collecting colostrum that is hand expressed from the breast, narrow end 820 for connecting with syringe 420, and multiple level indicators 816 to help a user determine how much colostrum resides within funnel 816. During use, the user may choose to collect colostrum using a breast pump with adapter 802 and reservoir 810, or using hand expression into funnel 816. The best practice for colostrum collection may often be to alternate between breast pump expression and hand expression. Reservoir 810 and funnel 816 are both designed to connect to syringe 420. As described above, syringe 420 is used to generate suction force to draw colostrum out of reservoir 810 or funnel 816. Once colostrum is pulled into syringe 420, syringe 420 may be detached and positioned in a newborn's mouth to directly deliver the colostrum to the newborn.
According to various embodiments, adapter 802, reservoir 810 and funnel 816 may be made of any suitable material, such as any hard plastic, metal, polymer or the like. In one embodiment, for example, adapter 802, reservoir 810 and funnel 816 are made of a biocompatible, hydrophobic polypropylene. System 800 will typically be disposable, but in some embodiments it may be sterilizable and reusable.
