The present application pertains generally the field of medical devices. More specifically, the present application pertains to devices, systems and methods for collecting colostrum from a breast and dispensing the colostrum to a newborn baby.
Colostrum is fluid produced by the mammary glands of mammals in late stage of pregnancy, such as just prior to giving birth, and sometimes even after pregnancy. Colostrum is the first nutritional liquid that comes out of the breast during lactation. Colostrum has higher protein content than ordinary milk, and contains antibodies to protect the newborn against disease. This highly nutritional liquid is packed with antibodies and other immune enhancing substances and is thus very important for healthy new born development. Colostrum is essentially newborn's first food, and helps the newborn transition to consumption of mature milk. Thus, it is important that colostrum be fed to newborns after birth.
Colostrum is produced at a very slow rate of several milliliters per hour and generally requires some form of pumping and or hand expression to cause it to exit the breast. In the first few days after birth, it is extremely important to breastfeed a newborn at least 8-12 times each 24 hours, and more often is even better. This allows the baby to get all the benefits of the colostrum and also stimulates production of a plentiful supply of mature milk.
Collection of colostrum is difficult, due to the small amount of volume produced, and existing breast milk pumps are not designed for the higher viscosity colostrum and/or the small volumes of colostrum produced and expressed from the breast. Besides pumps for breast milk, the generally accepted practice is to use whatever container is available to collect the colostrum. This could be a spoon, small cup, or small vial. Usually all of these containers require transfer to another container for administering (such as a syringe). This transfer of material leads to loss of colostrum when every precious drop counts.
Various techniques may be used to provide colostrum to newborn. For example, a medicine cup or a plastic spoon may be used to collect the colostrum from the mother's breast(s). In some cases, the collected colostrum is then transferred to a syringe, which is then used to administer the colostrum to the newborn. In other cases, the colostrum is administered to the baby directly from the cup or spoon.
In the case of humans, in certain situations, the newborn may be separated from the mother immediately after birth. For example, the newborn may need to be treated right after birth, such as due to premature birth, infection, or other medical conditions. In such cases, the mother would not be able to directly feed the newborn from her breasts. Other cases, such as maternal pain, newborn inability to effectively suck, etc., often prevent direct breast feeding in the early postpartum stage. Also, a mother may choose not to directly breastfeed the newborn, and may elect, instead, to use a device for administering the colostrum to the newborn.
Generally, the currently used techniques and devices for collecting and administering colostrum have a number of drawbacks. First, the current techniques involve expressing the colostrum into a first container, and then using a second, separate device, such as a syringe, to remove the colostrum from the first container and dispense it to the newborn. This process exposes the colostrum to air and thus possible germ contact, is inconvenient for mothers, and typically wastes at least some amount of colostrum in the transfer process. Second, the current techniques generally involve expressing colostrum into a relatively large container, such as a plastic cup or breast pump bottle. Colostrum is naturally produced in very small volumes, but mothers trying to express colostrum may often get discouraged when the colostrum appears to be incredibly small-volume relative to a large container. In summary, the current techniques do not work well for many nursing mothers and often cause a woman to give up on breast feeding during the first few days of a newborn's life.
Therefore, it would be desirable to provide methods, devices and systems for collecting colostrum from a breast and storing and/or dispensing the colostrum. Ideally, these methods, devices and systems would be easy to use and not intimidating to mothers. The methods, devices and systems would also ideally transfer colostrum from breast to newborn in an efficient way, so that very little colostrum is lost in the process.
The embodiments described herein relate to methods, systems and devices for collecting and dispensing colostrum. Although the embodiments will be described for use in collecting and dispensing colostrum, some or all embodiments may also be used for collecting and dispensing breast milk. Certain words will be used in this application to describe various embodiments, and these words should not be interpreted overly narrowly. For example, the term “system” or the phrase “connected system” may be used to describe a colostrum collection/administration system with multiple parts, at least some of which attach together during at least some portion of a collection/administration method. In various embodiments, these systems may include fewer or additional components, some of which attach and others of which may not attach. Similarly, the terms “dispensing” and “administering” may be used interchangeably, as may any other suitable synonym or similar word describing an action of feeding colostrum (and/or milk, in some embodiments) to a newborn.
One of the primary advantages of the methods, systems and devices described herein, which will be further explained below, is that they involve collecting colostrum in a device or connected system that is then conveniently used to administer the colostrum to the newborn. In other words, there is no need for transferring the colostrum from a first, collection vessel to a second, administration vessel. Although most if not all embodiments involve some kind of interface device for helping collect the colostrum, the interface device is connected, either directly or indirectly, to a colostrum administration device, such as a syringe or other suction-generating member. The syringe or other suction member can be actuated to draw the colostrum into a collection portion of the syringe or suction member, and then it can be removed from the interface and used to deliver the colostrum to the newborn.
In one embodiment, an interface device may be a colostrum collection device that is used to collect manually expressed colostrum and help direct it into a syringe or other containment/delivery device. In another embodiment, an interface device may be a breast pump shield adapter that is connected between a breast pump shield and a syringe or other containment/delivery device to direct colostrum from the breast shield into the containment/delivery device. In yet another embodiment, an interface device may be a combination colostrum collection device for use in manual expression and an adapter for use with a breast shield. Such a device may thus be used for both manual expression and breast pump expression of colostrum.
In one aspect, a method of using a system to collect colostrum from a breast of a human and using at least part of the system to dispense the colostrum to an newborn may involve: coupling an interface member with a suction member to form at least part of the system; positioning the interface member in contact with or near the breast; expressing colostrum from the breast, into the interface member; applying suction force to the interface member, using the suction member, to draw the colostrum into the suction member; detaching the interface member from the suction member; and dispensing the colostrum to the newborn from the suction member. In various alternative embodiments, the interface member may include, but is not limited to, a funnel, a suction cup, a bulb, a dome, a breast shield, a breast pump suction cup, a breast pump flange or an adapter.
In some embodiments, coupling the interface member with the suction member involves directly attaching the interface member to the suction member. In some of these embodiments, the suction member may be a syringe, one end of the interface member may include at least one thread on an outer surface, and attaching the interface member to the syringe may involve threading the at least one thread into at least one complementary thread on the syringe.
In some alternative embodiments, coupling the interface member with the suction member may involve coupling a first end of an adapter with the suction member, where the adapter is part of the system, and coupling a second end of the adapter with the interface member. In some of these embodiments, the suction member may be a syringe, the first end of the adapter may include at least one thread on an outer surface, and attaching the first end to the syringe may involve threading the thread into at least one complementary thread on the syringe. In some embodiments, the method may also include, before coupling the adapter with the suction member, selecting an adapter from a container holding at least three adapters, where each of the at least three adapters is configured to be used for one day of colostrum collection. In some embodiments, the interface member may be a breast pump shield, and the method may further include activating the breast pump to help pump colostrum from the breast.
In some embodiments, colostrum may be expressed, at least in part, via manual expression. In some embodiments, the step of positioning the interface member in contact with or near the breast may involve forming a seal between the interface member and a surface of the breast. In various alternative embodiments, the suction member may include, but is not limited to, a syringe, a bulb suction device, a cartridge or a vial. In embodiments where the suction member is a syringe, for example, dispensing the colostrum may involve positioning a distal end of the syringe in the newborn's mouth and pushing a plunger of the syringe to advance the colostrum out of the distal end of the syringe and into the newborn's mouth or nose. Alternatively, the method may further involve attaching a flexible tube to the syringe, after detaching the interface member, advancing a free end of the flexible tube into the newborn's mouth or nose and dispensing the colostrum to the newborn through the flexible tube.
In some embodiments, the interface member may be gripped using at least one ergonomic feature of the interface member. For example, such an ergonomic feature may include, but is not limited to, an overall shape, grooves, vertical protrusions, horizontal protrusions, diagonal protrusions and/or bumps. In various embodiments, the method may optionally include, before the coupling step, selecting the interface member from a package containing any suitable number of interface members.
Optionally, in some embodiments, the method may further involve using the system to collect breast milk from the breast and dispense the breast milk to the newborn. Also optionally, the method may involve storing the colostrum in the suction member before dispensing it to the newborn. In some embodiments, coupling the interface member with the suction member may involve engaging a locking member on the interface member with a complementary locking member on the suction member. In some embodiments, coupling the interface member with the suction member may form a seal between the interface member and the suction member. Optionally, some embodiments may include a step of coupling the interface member with a breast pump device before, during or after any step of the method.
In another aspect, a method of collecting colostrum from a breast of a human and dispensing the colostrum to a newborn may involve: coupling a first end of an adapter with a syringe; positioning a second end of the adapter in contact with or near the breast; manually expressing colostrum from the breast into the second end of the adapter; coupling the second end of the adapter with a breast pump shield; expressing colostrum from the breast, using the breast pump shield and a breast pump system attached to the breast pump shield; retracting a plunger of the syringe to cause the colostrum to move into the syringe from the adapter; detaching the adapter from the first end of the syringe; and dispensing the colostrum to the newborn from the syringe.
In some embodiments, coupling the first end of the adapter with the syringe may involve engaging threads on the adapter with complementary threads on the syringe. Alternatively, coupling the first end of the adapter with the syringe may involve press fitting a tapered distal end of the syringe into a tapered inner surface of the first end of the adapter. In some embodiments, coupling the second end of the adapter with the breast pump shield may involve engaging threads on the adapter with complementary threads on the breast pump shield.
In some embodiments, the step of manually expressing colostrum may precede the steps of coupling the steps of coupling the second end of the adapter with the breast pump shield and expressing colostrum from the breast, using the breast pump shield. Alternatively, the steps of coupling the second end of the adapter with the breast pump shield and expressing colostrum from the breast, using the breast pump shield, may precede the step of manually expressing colostrum, and wherein the method further includes detaching the breast pump shield from the adapter before the manual expression step.
In some embodiments, the method may further involve, after manually expressing the colostrum but before coupling the adapter with the breast pump shield, retracting the plunger of the syringe to cause the colostrum to move into the syringe from the adapter, wherein the retracting step is performed again after expressing colostrum from the breast, using the breast pump shield. In some embodiments, the method may further involve, before coupling the adapter with the syringe, selecting an adapter from a kit containing multiple adapters configured to attach to multiple different types of syringes. In some embodiments, dispensing the colostrum may involve positioning a distal end of the syringe in the newborn's mouth and pushing a plunger of the syringe to advance the colostrum out of the distal end of the syringe and into the newborn's mouth.
In another aspect, a combination collection/adapter device for facilitating the collection and administration of colostrum from a breast of a human to a newborn may include: a large-diameter end for collecting manually expressed colostrum and for attaching to a breast pump shield; at least one breast pump shield thread at or near the large-diameter end for coupling with one or more complementary threads on the breast pump shield; a small-diameter end for attaching to a syringe; at least one syringe thread on an external surface of the device at or near the small-diameter end for coupling with one or more complementary threads on a first type of syringe; a tapered inner surface of the small-diameter end, configured to mate with a distal end of a second type of syringe via press fit; and a tapered outer surface extending from the large-diameter end to the small-diameter end and configured to facilitate holding the device with one hand. Optionally, the device may further include at least one ergonomic feature disposed along the tapered surface for facilitating holding of the device. For example, the ergonomic feature may include, but is not limited to, an overall shape, grooves, vertical protrusions, horizontal protrusions, a textured surface, diagonal protrusions and/or bumps.
In another aspect, a device for collecting and administering fluid from a breast includes a container having a first end with a first opening for collecting fluid from the breast, and a second end with a second opening for administering the collected fluid, the second opening being smaller than the first opening, and a coupler for detachably coupling to the first end of the container, wherein the coupler comprises threads on an exterior surface for detachably coupling to a pump connector.
In another aspect, a device for collecting and administering fluid from a breast includes a container having a first end with a first opening for collecting fluid from the breast, and a second end with a second opening for administering the collected fluid, the second opening being smaller than the first opening, and a plunger configured to detachably couple to the first end of the container, wherein the container comprises a lip at the first end that circumferentially surrounds the first opening.
In another aspect, a method for collecting and administering fluid from a breast includes detachably coupling a pump connector to a container, the pump connector being a component of a pump system, wherein the container has a first end with a first opening, and a second end with a second opening, using the pump system to collect fluid from the breast, and using the container to receive the fluid through the first opening at the first end.
In another aspect, a kit for collecting and administering fluid from breast may include multiple units or parts of units of any of the devices described herein. For example, in one embodiment, a plastic bag may contain 20 parts and one instructions-for-use pamphlet. The 20 parts may include multiple funnels and adapters throughout a 2-day hospital stay. Each funnel and each adapter may be packaged individually to retain sterility. In another embodiment, a carton box may contain 20 “kit bags” and one instructions-for-use pamphlet. Each kit bag may contain a sterile funnel and sterile adapter. This kit bag may be adequate for a 4-6 hour period, for example. Any kit embodiment may also optionally include one or more feeding syringes. In some embodiments, for example the interfaces of the system/kit may be made by one manufacturer and packaged by that manufacturer with syringe(s) made by another manufacturer. Any of these kit embodiments may be advantageous for some hospitals, physicians, nurses and/or patients, for enhancing ease of use. Another optional feature of any of the kit embodiments may be an app or youtube link that shows a video of a mother using a device from the kit to further help the mother and nurse understand usage. A web link or app name could be printed on the instructions-for-use pamphlet, for example.

In the illustrated embodiments, the second end 26 of the container 12 has a protrusion 32 that defines the second opening 28. During use, when the container 12 is used to collect colostrum from a breast, the blocker 21 may be detachably coupled to the protrusion 32 that that it covers the second opening 28. For example, the blocker 21 may be configured (e.g., sized and/or shaped) to be inserted into the second opening 28 so that the blocker 21 is frictionally engaged with an interior surface of the protrusion 32. Alternatively, the blocker 21 may be configured (e.g., sized and/or shaped) to be placed around the protrusion 32 so that the blocker 21 frictionally engages with an exterior surface of the protrusion 32. When the blocker 21 is detachably coupled to the second end 26 of the container 12, it prevents fluid in the container 12 from exiting through the second opening 28 at the second end 26 of the container 12. It should be noted that the manner in which the blocker 21 is detachably coupled to the container 12 is not limited to the example discussed previously and that blocker 21 may be detachably coupled to the container 12 in other configurations. For example, in other embodiments, the blocker 21 may include a connector for detachably coupling to the second end 26 of the container 12. For example, the connector may include threads that are configured to threadingly engage with corresponding threads at the protrusion 32 (either at an exterior surface of the protrusion 32, or an interior surface of the protrusion 32) of the container 12. Furthermore, in other embodiments, the protrusion 32 is optional, and the container 12 may not include the protrusion 32. In such cases, the blocker 21 may be coupled to the container 12 by inserting the blocker 21 into the second opening 28 at a bottom surface of the container 12. Also, in other embodiments, the device 10 may further include a member (not shown) that connects the blocker 21 to the container 12. The member may have one end connected to the blocker 21, and another end connected to the container. The member prevents the blocker 21 from being separated from the container 12 even when the blocker 21 is not inserted into the second opening 28, thereby preventing the blocker 21 from getting lost.
After fluid has been collected inside the container 12, the blocker 21 may be removed from the container 12, and a first end 40 of the tube 20 may be detachably coupled to the second end 26 of the container 12 by inserting the first end 40 of the tube 20 into the second opening 28, so that the tube 20 is detachably coupled to the container 12 using friction. When the tube 20 is coupled to the container 12, a lumen in the tube 20 is in fluid communication with the second opening 28. A second end 42 of the tube 20 may be placed into a mouth of the subject. The tube 20 then functions as a feeding tube for delivering colostrum from the container 12 to the subject. In some embodiments, the tube 20 may be a 5 French feeding tube. In other embodiments, the tube 20 may have other dimensions.
In other embodiments, the tube 20 is optional, and the device 10 may not include the tube 20. In such cases, the protrusion 32 at the second end 26 of the container 12 may be placed directly into a mouth of the subject for administering the colostrum to the subject. It should be noted that the manner in which the tube 20 is detachably coupled to the container 12 is not limited to the example discussed previously, and that tube 20 may be detachably coupled to the container 12 in other configurations. For example, in other embodiments, the tube 20 may be configured (e.g., sized and/or shaped) so that it is placed around the protrusion 32 at the second end 26 of the container 12, and is detachably secured to the container using friction. Also, in other embodiments, the first end 40 of the tube 20 may include a connector for detachably coupling to the second end 26 of the container 12. For example, the connector may include threads that are configured to threadingly engage with corresponding threads at the protrusion 32 (either at an exterior surface of the protrusion 32, or an interior surface of the protrusion 32) of the container 12. Furthermore, in other embodiments, the protrusion 32 is optional, and the container 12 may not include the protrusion 32. In such cases, the first end 40 of the tube 20 may be coupled to the container 12 by inserting the first end 40 into the second opening 28 at the bottom surface of the container 12.

In the illustrated embodiments, the coupler 16 has a ring configuration, and includes threads 60 at an exterior surface 62 of the coupler 16. The coupler 16 is configured to detachably couple to the first end 22 of the container 12 during use. As shown in the illustrated embodiments, the coupler 16 has a latch that extends circumferentially around the coupler 16, which allows the coupler 16 to detachably couple to the lip 31 of the container by a snap-fit connection. When the coupler 16 is coupled to the container 12, the coupler 16 may be used to detachably couple to a pump connector of a pump system, so that the pump system may be used to collect fluid (e.g., colostrum, milk) from a breast, and deliver the fluid into the container 12.
As shown in
In other embodiments, instead of providing the tabs 220 for turning the coupler 200, the plunger 18 may have other mechanisms for turning the coupler 200. For example, in other embodiments, the shaft 202 of the plunger 18 may have a groove that slidingly mates with a protrusion at an interior surface of the coupler 200. Such configuration allows the shaft 202 to slidingly move relative to the coupler 200 along a longitudinal axis of the shaft 202, while also allowing the coupler 200 to be turned about the longitudinal axis of the shaft 202 by turning the actuator 204 about the longitudinal axis of the shaft 202.
During use, the plunger 18 may be detachably coupled to the container 12. In particular, the coupler 16 may be used to couple the plunger 18 to the container 12 by detachably securing the lip 31 of the container 12 to the circumferential latch of the coupler 16 via the snap-fit connection, and by detachably securing the plunger 18 to the top portion of the coupler 16 using the threads 208 and 64 (i.e., by turning the coupler 200 of the plunger 18 relative to the coupler 16 using the tabs 220). The actuator 204 may then be used to advance the plunger head 206 inside the compartment 30 of the container 12 to push fluid out of the second opening 28 at the second end 26 of the container 12.
It should be noted that the manner in which the plunger 18 is coupled to the container 12 is not limited to the embodiments described. In other embodiments, the plunger 18 may be directly or indirectly coupled to the container 12 using other mechanisms. For example, in other embodiments, the coupler 200 of the plunger 18 may be screwed into the container 12, having corresponding threads at an interior surface of the container 12 at the first end 22. In further embodiments, the coupler 200 of the plunger 18 may not have threads 60. Instead, the coupler 200 of the plunger 18 may be configured to secure itself directly to the container 12 using a snap-fit connection, a frictional engagement, or any of other types of connection. In still further embodiments, the coupler 200 of the plunger 18 may be configured to secure itself directly to the coupler 16 (and indirectly to the container 12) using a snap-fit connection, a frictional engagement, or other types of connection.

In any of the embodiments described herein, the container 12 may include one or more markings for indicating target fluid level(s).
In the above embodiments, the markings 500a-500c represent different respective ranges of target volume. In other embodiments, the markings 500a-500c may represent different target volume levels (i.e., instead of ranges of levels). Also, in the above embodiments, the markings 500a-500c indicate different respective ranges of fluid volume desired to be collected in different days after childbirth. In other embodiments, instead of “day(s)” after childbirth, the markings 500a-500c may correspond with different hour(s) after birth, number of meals, or other units that correspond with passage of time. In further embodiments, instead of three markings 500a-500c, the container 12 may include less than three markings or more than three markings. Also, in other embodiments, instead of, or in addition to, the configuration shown, the markings 500a-500c may include numerical information on the container 12, such as volume levels (e.g., in unit of ml, cc, etc.), “1” in the region for marking 500a, “2” in the region for marking 500b, and “3” in the region for marking 500c.
In any of the embodiments described herein, any of the components of the device 10 may be made from a suitable polymer, plastic, silicone, other materials, or combination thereof. In some cases, any components of the device 10 (e.g., the container 12, plunger 18, lid 300) that may potentially come into contact with breast fluid may be made from a BPA-free material.
Also, in any of the embodiments, the container 12 may have a size that is smaller than a size of a baby bottle. For example, in any of the embodiments described herein, the container 12 may have a total height that is anywhere between 0.5 inch and 3 inches, and more preferably, between 1 inch and 2 inches (e.g., 1.5 inch). Also, in some embodiments, the container 12 may be configured to hold at most 40 ml of fluid, and more preferably, at most 30 ml of fluid, or less. Such size feature is advantageous, because the amount of colostrum produced by a mother may not be significant, and if a large container (e.g., a baby bottle) is used to collect the colostrum, a mother may be discouraged from breastfeeding when she sees that there is very little colostrum relative to the size of the container. Thus, providing a container 12 that is smaller than a size of a baby bottle has functional reasons, and is not a matter of design choice.
A method of using the device 10 in accordance with some embodiments will now be described. First, to set up the device 10 for collecting breast fluid (e.g., colostrum, milk), the plunger 18 is separated from the container 12 by turning the coupler 200 of the plunger 18 relative to the coupler 16 (e.g., using the tabs 220) until the threads 208 and 64 are decoupled from each other. The coupler 16 is detachably coupled to the first end 22 of the container 12 by snap-fitting the edge of the coupler 16 against the lip 31 of the container 12, and the suction cup 400 of a pump system is detachably coupled to the coupler 16 by screwing the coupler 16 relative to the connector 402 of the suction cup 400. Thus, the suction cup 400 is secured to the container 12 through the coupler 16. The blocker 21 is then used to cover the second opening 28 at the second end 26 of the container 12. The suction cup 400 is placed over the breast, and the pump system is then activated to create suction at the suction cup 400, thereby expressing or extracting breast fluid out of the holes in the nipple at the breast. The collected breast fluid enters the container 12 through the first opening 24 at the first end 22 of the container 12, and is contained in the compartment 30 of the container 12.
In other embodiments, instead of using a pump system to collect the colostrum/milk, hand expression may be employed to collect the colostrum/milk. In such cases, the coupler 16 may be removed from the container 12 (
After the breast fluid has been collected, the suction cup 400 is detached from the coupler 16. If hand expression was used to collect the breast fluid, the coupler 16 is then detachably coupled to the container 12. The plunger 18 is then detachably coupled to the first end 22 of the container 12 through the coupler 16. In particular, the plunger 18 is inserted into the top portion of the coupler 16, and is turned using the tabs 220 to threadingly engage the threads 208 at the plunger 18 against the threads 64 at the interior surface 66 of the coupler 16. After the plunger 18 is mounted, the plunger head 206 functions as a seal to prevent the collected breast fluid in the container 12 from leaking out of the first opening 24 of the container 12. With both the first and second openings 24, 28 covered and sealed, the container 12 may then be used to transport the collected breast fluid from the mother to a subject.
Alternatively, instead of using the plunger 18 to seal the first end 22 of the container 12, the lid 300 may be used to cover the first opening 24 at the first end 22 of the container 12. In such cases, the coupler 16 is not coupled to the container. Instead, the lid 300 is snap-fit against the lip 31 of the container 12 to thereby seal the first opening 24 at the container 12 (
In some cases, when a nurse or a personnel at a hospital is not ready to transport the collected breast fluid, or when the mother wishes to collect more breast fluid before the container 12 is delivered to the subject, the second end 26 of the container 12 may be placed into the recess 50 of the base 14, and the container 12 may be vertically supported by the base 14.
Once delivered to the subject, the container 12 with the breast fluid may then be used to feed the subject. If the plunger 18 is already coupled to the container 12, the container 12 may then be turned upside down, and the blocker 21 is then removed from the second end 26 of the container 12. On the other hand, if the plunger 18 is not already coupled to the container 12 (i.e., if the lid 300 is on the container), the lid 300 may first be removed from the container 12, and then the coupler 16 and the plunger 18 may be coupled to the container 12.
In some embodiments, the protrusion 32 at the second end 26 of the container 12 may be placed into the subject's mouth. The user of the device 10 may then advance the plunger head 206 inside the container 12 by pressing on the actuator 204 of the plunger 18, thereby pushing the breast fluid out of the second opening 28 and into the subject's mouth. In other embodiments, the first end 40 of the feeding tube 20 may be detachably coupled to the second end 26 of the container 12, and the second end 42 of the feeding tube 20 may be placed inside the subject's mouth. The user of the device 10 may then advance the plunger head 206 inside the container 12 by pressing on the actuator 204 of the plunger 18, thereby pushing the breast fluid out of the second opening 28, into the feeding tube 20, and into the subject's mouth.
When the feeding is completed, or if the person feeding the subject wishes to temporarily stop the feeding, the second opening 28 of the container 12 may be closed by using the blocker 21, and the container 12 may be vertically supported by the base 14. In some embodiments, the device 10 includes one base 14, in which cases, when the container 12 is being delivered from the mother to the subject, the base 14 may also be delivered together with the container 12 so that the person feeding the subject may use the base 14 to support the container 12 if desired. In other embodiments, the device 10 may include two bases 14. In such cases, one base 14 may stay with the mother so that she can use the base 14 to support the container 12, and the other base 14 may stay with personnel at the hospital so that the personnel feeding the subject can use the base 14 to support the container 12.
In some embodiments, all of the components of the device 10 are for a single use. In other embodiments, any one or more of the components (such as the base 14) of the device 10 may be for multiple use.
As illustrated in the above embodiments, the device 10 is advantageous because the same device 10 may be used for collecting colostrum/milk, storing the colostrum/milk, transporting the colostrum/milk, and administering the colostrum/milk to a subject. Thus, the device 10 obviates the need to transfer colostrum/milk from a medicine cup, spoon, pump bottle, or other containers, to another container for administering the fluid to the subject. The device 10 is also advantageous, because it provides two modes of breast fluid collection, wherein in the first mode, the device 10 is detachably coupled to a pump system to receive breast fluid from the pump system, and in the second mode, the device 10 is not detachably coupled to any pump system, but is placed directly next to a breast for collecting breast fluid resulted from hand expression. The device 10 promotes feeding the newborn with human colostrum/milk, which in turn may result in lower health care costs, and many other benefits.
Although embodiments of the device 10 have been described with reference to the device 10 having the coupler 16, in other embodiments, the coupler 16 is optional, and the device 10 may not include the coupler 16. In such cases, instead of using a pump system to collect colostrum/milk into the container 12, the colostrum/milk may be collected into the container 12 manually by using hand expression. After the breast fluid has been collected into the container 12, the plunger 18 may then be inserted into the compartment 30 of the container 12 to push the fluid out of the second opening 28 of the container 12.
In still further embodiments, the device 10 may include the coupler 16, but the coupler does not include the threads 60 or any other mechanism for coupling to a pump connector. In such cases, instead of using a pump system to collect colostrum/milk into the container 12, the colostrum/milk may be collected into the container 12 manually by using hand expression. After the breast fluid has been collected into the container 12, the coupler 16 may then be used to detachably couple the plunger 18 to the first end 22 of the container, as similarly discussed. The plunger 18 may then be used to push the fluid out of the second opening 28 of the container 12.
In the above embodiments, the second opening 28 has been illustrated as being at the bottom surface of the container 12. In other embodiments, the second opening 28 may be implemented at other locations on the container 12. For example, in other embodiments, the second opening 28 may be implemented at a side of the container 12 (
Also, in further embodiments, the plunger 18 may be at other locations. For example in other embodiments, the container 12 may include a side opening at the side wall of the container 12 that is configured to allow an insertion of the plunger 18. In such cases, while the first opening 24 of the container 12 is being used to collect colostrum/milk, the plunger 18 may remain coupled to the side of the container 12. After the colostrum/milk is collected into the container 12, the lid 300 may be used to cover the first opening 24, or the top of the coupler 16 (if the coupler 16 is already coupled to the container 12). The blocker 21 is then removed from the second opening 28 of the container 12. The plunger 18 at the side of the container 12 may then be actuated to push the collected colostrum/milk out of the second opening 28, either directly from the second opening 28 into a subject's mouth, or from the second opening 28 into a feeding tube.

In any given embodiment, the system 100 may include a smaller subset of the components shown in
In use, the adapter 102 attaches at a first end 108 to an end 112, 114 of one of the syringes 104, 105 and at an opposite, second end 110 to an end of the interface 116. Once the system is coupled together, the user may then contact the interface 106 with the breast and apply suction force via the syringe 104, 105, a breast pump connected to the interface 106, or both. Typically, using the system 100 as illustrated in
One important feature of the system 100 is that colostrum is collected into a predominantly closed receptacle (i.e., one of the syringes 104, 105 in the embodiment of
Another likely advantage of the system 100 and other system embodiments described herein is that they are designed to be less intimidating to the women who use them. For example, the current method of expressing colostrum into a cup, bottle or similar container typically involves the use of a large collection container. The amount of colostrum expressed at one time, however, is almost always very small—just a few milliliters. Women may often become intimidated and discouraged, because the amount of colostrum they express, which is likely a very normal amount, will typically look like almost nothing when housed in a large collection vessel. By contrast, the system 100 uses relatively small-volume syringes 104, 105 (or other small-volume suction members in other embodiments). In the example shown in
In various embodiments, the interface 106 may allow suction force, mechanical force, oscillation force, electric stimulation, other force(s) or combinations thereof to be transmitted to the breast. The interface 106 also simultaneously serves as a conduit for colostrum collection. The interface 106 may have a shape of a funnel, bulb, dome, or any other suitable shape, and is sufficiently flexible to allow for maximal apposition or partial apposition with breast tissue to reduce dead volume and thus minimize colostrum loss. The interface may cover all or part of the nipple, areola or breast, and may or may not allow for manual expression or other colostrum expression techniques to be applied simultaneously. In some embodiments, ridges, grooves, bumps, regions of hydrophobic and hydrophilic coatings to guide material, electro-responsive strips, and/or other structures may be added to the internal surface of the interface 106 to serve as flow channels for colostrum. The internal volume of the interface 106 is configured to minimize wasted colostrum during the collection process.
The interface 106 connects to the collection/suction vessel 104, 105 in a detachable manner. This detachable interface 106 may include one or more components that are flexible, such as a tube or ridged such as a L shape bend, T connector, or other connection configuration such that the colostrum may flow from the collection area into a container such as a syringe, vial, cartridge, or other containment vessel for the colostrum. Such detachable connection may be achieved in a screw-on manner, through a Luer connection, click connector, pin connector, cone and socket, magnetic link, stopcock valve connector, squishing valve, or other standard or unique connection mechanism. In addition, the sizing of the connector may be such that standard interfaces may be used with the collection/suction vessel 104, 105, or the interface 106 may be used with standard collection vessels and suction mechanisms. The connector mechanism may be an independent component with one or multiple connection ports, or may be achieved through design features of the interface and collection/suction member 104, 105. This may be achieved, for example, by the interface 106 having threading at the base of its interior surface, and the collection/suction member 104, 105. Any embodiment of a valve may be included, in various embodiments, to facilitate temporary or long term separation of the collection/suction member 104, 105 and the interface 106. Multi-directional valves may also be contemplated, to allow for colostrum diversion to alternate collection vessels or to provide additional suction force or any mechanism to otherwise alter pressure, volume or contents of the collection/suction member 104, 105 or interface 106.
In some embodiments, such as the one illustrated in
The collection/suction vessel 104, 105 (syringe or other embodiment) may optionally include one of a number of suitable coatings to reduce adherence and/or facilitate collection of colostrum, milk, and or its components, such as but not limited to antibodies. The syringe 104, 105 may be constructed with antibacterial properties and may be constructed of a material that allows for the colostrum to undergo processes such as pasteurization. The syringe plunger may have a locking mechanism to maintain the plunger in such a position to generate a sustained suction force. Additionally, the syringe 104, 105 may have a locking mechanism composed of venting gas, a rotating counterweight, an oscillating spring, and/or other mechanism that oscillates, such that the suction force could be dynamic at least for a period of time. When detached from the interface 106, the collection/suction vessel 104, 105 may be used to dispense the colostrum directly into the mouth, hold the material for storage, or transfer to another vessel. The collection/suction vessel 104, 105 may have a cap to cover the orifice to facilitate storage, reduce potential contamination or spillage concerns and/or facilitate transport once detached from the interface 106. The collection/suction vessel 104, 105 may also optionally include an additional add-on component, such as a nipple piece that may be screwed on to facilitate feeding once the collection/suction vessel 104, 105 has been detached from the interface 106. The collection/suction vessel 104, 105 may also optionally include a component capable of applying cyclic suction force by way of moving the plunger in a repetitive motion and manipulation of a valve, which may or may not be connected to an additional reservoir. Such an effect may be achieved by an electric motor, an oscillating weight that is set at least partially off center to provide a swinging counter weight, a pre-stressed or elastic or spring mechanism designed to release energy in a cyclic fashion once an initial loading force is applied, or other suitable mechanism.
Any of the abovementioned components may be composed of any combination of coated or uncoated paper, plastics, polymer, glass, rubber, biodegradable substances, wax or gels. Any component may be foldable or otherwise pre-stressed, to facilitate storage for transport. Any component may be disposable or reusable. Any component may be composed of a substance that would tolerate traditional sterilization mechanisms, including but not limited to autoclaving, gamma irradiation or ethylene oxide.

In various embodiments, the breast pump shield thread(s) 404 may be compatible with any known or yet-to-be-invented breast pump shield. In some embodiments, the thread(s) 404 of one combination device 400 may be compatible with one or more complementary threads of multiple different breast shields. Alternatively, each device 400 may be compatible with one or more breast shields but not all breast shields, and multiple different devices 400, each having different breast shield threads 404, may be available for compatibility with different breast pump systems. Similarly, in various embodiments, the syringe thread(s) 408 may be compatible with any known or yet-to-be-invented syringe. Alternatively, if a colostrum collection device other than a syringe is used, the syringe thread(s) 408 may be designed to be compatible with such device(s). In some embodiments, the syringe thread(s) 408 of one combination collection/adapter device 400 may be compatible with one or more complementary threads of multiple different syringes. Alternatively, each device 400 may be compatible with one or more syringes but not all syringes, and multiple different devices 400, each having different syringe threads 408, may be available for compatibility with different breast pump systems.
In the embodiment shown in
In various embodiments, the combination device 400 may have any suitable size, shape, contour and overall design, as long as the collection end 402 is compatible with a breast pump shield and the syringe end 406 is compatible with a syringe or other colostrum collection device. In the embodiment shown, the surface of the device 400 contours/tapers gradually from the collection end 402 to the syringe end 406, and this shape may provide ergonomic advantages, in that it is likely easy for a user to hold in one hand. The optional grip members 412 may also facilitate holding the device 400 in one hand and may help prevent the device 400 from slipping out of the hand. In various alternative embodiments, the grip members 412 may be replaced with other types/shapes of grip members, a textured surface and/or the like. As with all the embodiments described thus far, the device 400 may be made of any suitable material, such as but not limited to plastic. The device 400 is typically disposable but may alternatively be made of a material that can be sterilized after use and reused.
