The disclosure relates generally to devices and methods used during breastmilk expression. In particular, the disclosure relates to devices and methods used to more efficiently and effectively collect colostrum during breastmilk expression.
Just prior to giving birth, expecting mothers begin producing colostrum vital to the health, growth, and vitality of a newborn. In particular, colostrum typically includes high amounts of bioactive compounds that aid in the health, growth, and vitality of newborn children when compared to mature milk. For example, colostrum contains antibodies that protect the newborn against disease and infection, immune and growth factors, and other bioactives that help to activate a newborn's immune system, jumpstart gut function, and seed a healthy gut microbiome in the first few days of life. However, colostrum is a highly viscous liquid that sticks or otherwise adheres to surface(s) after contact with the surface(s). As a result, colostrum often contacts and adheres to the surfaces of a device used to express breastmilk during breastmilk expression. Disadvantageously, colostrum may be lost during breastmilk expression as the expressed breastmilk flows through the device used to express breastmilk.

These and other features and advantages of the various examples disclosed herein will be better understood with respect to the following descriptions and drawings, in which:
A colostrum collection container as disclosed herein collects colostrum during breastmilk expression and maintains a continuous, clinical vacuum while allowing fluid to flow therethrough. The colostrum collection device is coupled to a breastshield and permits fluid flow from the breastshield to a connector. So configured, the colostrum collection device comes into contact with the expressed breastmilk and colostrum shortly after expression, which limits the number of surfaces that the colostrum contacts. Advantageously, because of the colostrum's propensity to stick to surfaces due to the high viscosity of the fluid, the configuration increases the likelihood that the greatest amount of colostrum is collected during breastmilk expression.
As illustrated in
The colostrum collection container 108 is configured such that the second fluid passes through the colostrum collection container 108 and into the connector 112, while the first fluid is collected with gravity assistance in the colostrum collection container 108. Such a configuration allows the first fluid to be collected shortly after the expression of the second fluid. Early collection of the first fluid during breastmilk expression advantageously increases the chances that the greatest possible amount of the first fluid is collected because the first fluid is more viscous than the second fluid and has fewer surfaces to interact with before reaching the colostrum collection container 108. Once the colostrum collection container 108 is filled to a maximum capacity with the first fluid, additional quantities of the first fluid expressed with breastmilk flow through the colostrum collection container 108 and into the connector 112. While not illustrated herein, an overflow container may be coupled to the connector 112 that retains the second fluid and additional quantities of the first fluid.

In addition, the connector 212 includes a housing 288, a first opening 288a, a second opening 288b, and a valve mechanism 292 disposed, at least in part, within the housing 288 between the first and second openings 288a, 288b. The valve mechanism 292 can be, for example, any valve mechanism as is known in the art. The second end 288b of the connector 212 may include threads or any suitable mechanism for releasable attachment to the overflow container 296, such as a milk bottle or the like. The connector 212 also includes a channel 300 for conducting expressed breastmilk from the colostrum collection container 208 and into the container 296.
As best illustrated in
The divider 228 is sealingly coupled to the body 224 proximate the first opening 224a and extends from the first opening 224a toward the second opening 224b of the body 224. As illustrated in
Importantly, and as depicted in
The aperture 232 is disposed on the divider 228 such that a fluid flow path 256 (
The aperture 232 and the gap 260 cooperate to selectively permit fluid flow from the first opening 224a of the body 224 of the colostrum collection container 208 to the second opening 224b of the body 224. In particular, the orientation, size, and placement of the aperture 232 and the size and the placement of the gap 260 can be configured such that fluid flows in only one direction. In other words, in this example, fluid flows from the first opening 224a of the body 224 of the colostrum collection container 208 through the aperture 232 and to the second opening 224b of the body 224, but fluid cannot flow from the second opening 224b through the aperture 232 and into the colostrum collection container 208.
As depicted in
As further depicted in
The third visual indicator 264c may also be disposed on either the body 224 or the divider 228 of the colostrum collection container 208 and designates a location of the aperture 232. For example, as illustrated in
The at least one visual indicator 264a, 264b, 264c may designate the location of the aperture 232. This may aid a user in locating the aperture 232 in the event that there is an interruption in fluid flow through the colostrum collection device 208. For example, the aperture 232 can be disposed on the divider 228 such that when the first fluid disposed in the first chamber 242 is below the at least one visual indicator 264a, 264b, 264c, the second fluid flows through the fluid flow path from the first chamber 242 to the second chamber 246. In other examples, the aperture 232 can be disposed on the divider 228 such that when the first fluid disposed in the first chamber 242 is at or above the at least one visual indicator 264a, 264b, 264c, the first and second fluids flow through the fluid flow path from the first chamber 242 to the second chamber 246.
Referring now to
While the colostrum collection container 208 has been discussed as being slidably received by the connector 212, the colostrum collection container 208 may be coupled to the connector 212 in a different manner. For example, the second opening 224b of the colostrum collection container 208 can be threaded and the first opening 288a of the connector 212 can be threaded in a manner complimentary to the threads of the second opening 224b. In such an example, the threaded nature of the colostrum collection container 208 and the connector 212 can reduce the likelihood that the colostrum collection container 208 and the connector 212 disconnect during use. Advantageously, such a configuration could reduce, if not eliminate, spilling the colostrum retained in the colostrum collection container 208.

More specifically and referring now to
In particular, once the vacuum is created in the breastshield 204 thereby expressing breastmilk, the second fluid (e.g., the expressed breastmilk) flows from the breastshield 204 to and through the colostrum collection container 208, and into the connector 212, as depicted by the third set of arrows 312. As the second fluid (e.g., the expressed breastmilk, the air) flows through the breastmilk expression system 200 (the third set of arrows 312), the first fluid (e.g., the colostrum) initially expressed along with the second fluid (e.g., the breastmilk) flows from the breastshield 204, into the colostrum collection container 208, through the aperture 232, and into the connector 212, as depicted by the fourth set of arrows 316.
More specifically, and in this example, when the first fluid (e.g., colostrum) disposed in the receptacle 228 is at or above the at least one visual indicator 264, the first and second fluids flow from the first opening 224a through the aperture 232 and to the second opening 224b of the body 224. In one example, the first fluid may initially flow from the first opening 224a of the body 224 and into the receptacle 228, but then ultimately flows through the aperture 232 and to the second opening 224b, which leads to the connector 212, as explained above.
In view of the foregoing, it is understood that the colostrum collection container 108, 208 used in the breastmilk expression system 100, 200 may employ the following method for collecting colostrum during breastmilk expression. For example, the method can include providing the colostrum collection container 108, 208 that includes the first opening 224a, the second opening 224b, a receptacle 228 disposed between the first and second openings 224a, 224b and having the aperture 232, and the fluid flow path 256 including the first opening 224a, the second opening 224b, and the aperture 232. Once the colostrum collection container 108, 208 is provided, the method includes creating a vacuum in a portion of the fluid flow path 256 and selectively permitting fluid flow from the first opening 224a to the second opening 224b of the colostrum collection container 108, 208 via the aperture 232 and the vacuum. When the vacuum is created, the method then includes collecting the first fluid in the receptacle 228 of the colostrum collection container 108, 208 with gravity assistance and the vacuum while the second fluid continues to flow from the first opening through the aperture 232 and to the second opening 224b of the colostrum collection container 108, 208.
In the example method of collecting colostrum discussed above, providing the colostrum collection container 108, 208 can further include disposing the at least one visual indicator 26a, 264b, 264c on the body 224 such that a visual indicator of the at least one visual indicator 264a, 264b, 264c designates a maximum fluid capacity of the body 224. The example method of collecting colostrum can further include collecting the first fluid in the receptacle 228 when the first fluid in the receptacle 228 is below the at least one visual indicator 264a, 264b, 264c while the second fluid flows through the fluid flow path 256 from the receptacle 228 to the second opening 224b. The example method of collecting colostrum can also include collecting the first fluid in the receptacle 228 until the first fluid in the receptacle 228 is at or above the at least one visual indicator 264a, 264b, 264c, at which time at least one of the first fluid and the second fluid flows through the fluid flow path 256 from the receptacle 228 to the second opening 224b.
The example method of collecting colostrum can further include coupling a cap 272 to the body 224 of the colostrum collection container 104, 204. The cap 272 has the base 276 and the sealing member 280 that extends from the base 276 to at least the aperture 232 when the cap 272 is coupled to the body 224 thereby sealing the aperture 232. In some examples, providing the colostrum collection container 108, 208 can further include disposing the visual indicator 264a, 264b, 264c on the body 224 that is oriented at an angle α relative to a vertical axis 268 of the body 224 such that when the body 224 is canted, the visual indicator 264a, 264b, 264c designates a maximum fluid capacity of the body 224.
In view of the foregoing, it is understood that the colostrum collection container 108, 208 used in the breastmilk expression system 100, 200 may employ the following method for assembling the colostrum collection container 108, 208. For example, the method of assembling the colostrum collection container 108, 208 can include providing the body 224 with the first opening 224a and the second opening 224b; disposing the receptacle 228 within the body 224 and coupling a portion of the receptacle 228 to the body 224, the receptacle 228 including a wall 228a with an aperture 232; and forming the fluid flow path 256 including the first and second openings 224a, 224b and the aperture 232 of the receptacle 228, such that when a vacuum is generated in the fluid flow path 256, the first fluid is permitted to be collected in the receptacle 228 and the second fluid is permitted to flow through the aperture 232 and to the second opening 224b.
The example method of assembling the colostrum collection container 108, 208 discussed above can further include disposing the assembly guide 234 proximate to the first opening 224a of the body 224. In some examples, the method can further comprise coupling a breastshield 104, 204 to the first opening 224a of the body 224 using the assembly guide 234. The example method of assembling the colostrum collection container 108, 208 can further include disposing the at least one visual indicator 264a, 264b, 264c on the body 224 such that a visual indicator of the at least one visual indicator 264a, 264b, 264c designates a maximum fluid capacity of the body 224.
Moreover, forming the fluid flow path 256 described in the example method of assembling the colostrum collection container 108, 208 can further include forming the aperture 232 on the on the receptacle 228 such that when the first fluid in the receptacle 228 is below the at least one visual indicator 264a, 264b, 264c, the second fluid flows from the first opening 224a through the aperture 232 and to the second opening 224b of the fluid flow path 256. In some examples, forming the fluid flow path 256 includes forming the aperture 232 on the receptacle 228 such that when the first fluid in the receptacle 228 is at or above the at least one visual indicator 264a, 264b, 264c, the first and the second fluid flow from the first opening 224a through the aperture 232 and to the second opening 224b of the fluid flow path 256. The method of assembly, in some examples, can further include coupling a cap 272 to the body 224. The cap 272 having a base 276 and a sealing member 280 that extends from the base 276 to at least the aperture 232 when the cap 276 is coupled to the body 224.
In view of the foregoing, it will be understood that the breastmilk expression system 100, 200 and related methods of the present disclosure have several advantages. For example, the aperture 232 of the colostrum collection container 108, 208 forms a fluid flow path 256 from the first opening 224a through the aperture 232 and to the second opening 224b, which can maintain a clinical vacuum and selectively permit fluid flow of a second fluid (e.g., breastmilk, air) through the aperture 232 while retaining the first fluid (e.g., colostrum) in the colostrum collection container 108, 208. As another example, placement of the colostrum collection container 108, 208 within the breastmilk expression system 100, 200 allows the colostrum expressed during breastmilk expression to contact the least amount of surfaces throughout the breastmilk expression system 100, 200, which can increase the amount of colostrum collected. As yet another example, the assembly guide 234 of the colostrum collection container 108, 208 aids in assembly of the breastmilk expression system 100, 200 by selectively permitting the colostrum collection container 108, 208 to receive certain other components of the breastmilk expression system 100, 200. Finally, as another example, the cap 272 that is sealingly coupled to the body 224 of the colostrum collection container 108, 208 can seal the aperture 232 and securely retain the collected colostrum in the colostrum collection container 108, 208 during transportation and storage, providing yet another benefit.
While various examples have been described above, this disclosure is not intended to be limited thereto. Variations can be made to the disclosed examples that are still within the scope of the appended claims.
