Detailed description

[0017] Before turning to the accompanying drawings, which illustrate exemplary embodiments in detail, it should be understood that this application is not limited to the details or methods set forth in the description or shown in the drawings. It should also be understood that terminology is used for descriptive purposes only. The same reference numerals in the drawings may denote and refer to the same or similar elements, features, or functions.

[0018] This article details systems and methods for improving nutrient savings in fluid containment and distribution systems. Collecting, containing, and distributing liquids such as emulsified nutrients (e.g., human milk) presents numerous technical challenges and can be difficult and arduous. For example, the nutritional composition of human breast milk consists of several beneficial macromolecules, including lipids, proteins, and carbohydrates. Of these, lipids hold the greatest potential for ensuring nutrient uptake from HBM. Although lipids comprise only 5% of breast milk volume, they account for 50% of an infant's daily energy intake. Preterm infants can absorb 95% of human milk fat; however, on average, only 5% of HBM is fat and fat-soluble components, including many vitamins. These fats and fat-soluble components constitute the majority of calories in HBM, thus maximizing lipid (i.e., fat) delivery is desirable.

[0019] Studies have shown that, due to its molecular properties, the fats in HBM tend to adhere to the blood vessels through which it passes during collection, preparation, processing, and delivery. Furthermore, many newborns with HBM cannot be directly breastfed due to factors such as underdeveloped digestive systems, the presence of a ventilator, or general lack of strength. In some cases, providing nutrition through enteral feeding may be necessary. Ensuring adequate nutrition for the patient allows for normal growth and organ development and helps overcome preterm health conditions. Generally, HBM is particularly well-suited to the nutritional needs of infants and is an active substance with unparalleled immunological and anti-inflammatory properties, protecting both mother and infant from a variety of diseases and illnesses.

[0020] The nutrient-saving container systems and methods described herein provide solutions to these and other technical problems through improved equipment (e.g., collection containers and / or accessories used therewith) to improve nutrient (e.g., HBM nutrients) savings during feeding processes such as enteral feeding. For example, the collection container and plunger rod provide the user with the flexibility to selectively scrape and aspirate one or more containers that can be used in the collection, preparation, storage, and / or delivery of liquid nutrients. Advantageously, the systems and methods described herein offer improved nutrient savings and ergonomics.

[0021] Now for reference Figures 1-4 and Figures 12-17According to some embodiments, the nutrient collection system 10 includes a collection container 100, such as a collection bottle, having a variable capacity. The collection container 100 may have an elongated body 112 extending along a longitudinal axis 111 between a first end 114 (e.g., the bottom end) and a second end 116 (e.g., the top end), defining an internal volume 118 between the first end 114 and the second end 116. For example, the elongated body 112 may be a cylindrical body with an internal bore. In some embodiments, the sidewall 120 of the elongated body 112 has an inward-facing surface shown as an inner surface 122 and an outward-facing surface shown as an outer surface 124. One of the first end 114 and the second end 116 (e.g., the second end 116) is an open end configured to receive a cap 130 to seal the collection container 100 and / or connect to a lactation pump head 132 of a breast milk collection device 134, such as a funnel or breast pump shield 136 connected to a pump 138. In some embodiments, the first end 114 of the collection container 100 may be coupled to an adapter to allow the attachment of collection containers 100 of different sizes (e.g., larger collection containers) to the lactation pump head 132 / milk shield 136. The attachment to the adapter allows the user to customize the size of the nutrient collection system 100 and / or the lactation pump head 132 to suit their needs. In some embodiments, the open end 116 may include engagement features 140, such as threaded portions (e.g., male threads), configured to engage corresponding engagement portions 142, such as the cap 130 of the breast milk collection device 134 and / or the corresponding threaded portions (e.g., female threads) of the lactation pump head 132. The other of the first end 114 and the second end 116 (e.g., the first end 114) may have a base plate 152 (e.g., a piston) that forms an opposing end containing a volume 150 within the internal volume 118 of the elongated body 112. In some embodiments, the collection container 100 has graduations and / or the sidewalls 120 include a plurality of markings 156 indicating the position of the volume of the internal volume 150 of the collection container 100 relative to the base plate 152 along the longitudinal axis 111.

[0022] In some embodiments, the movable base plate 16 has a shape substantially the same as the cross-sectional shape of the elongated body 12, such that the movable base plate 152 can seal the end of the elongated body 112. In some embodiments, the movable base plate 152 is slidably mounted within the inner bore of the elongated body 112.

[0023] In some embodiments, the movable base plate 152 may have a sealing portion 160 configured to maintain a sealing contact between the base plates 152. For example, the sealing portion 160 may include a gasket 162 surrounding its outer peripheral edge (shown as outer edge 302) (see example...). Figures 29 to 46In some embodiments, gasket 162 may be inserted into channel 164 (e.g., groove, compression ring groove, O-ring groove, etc.) around the periphery of movable base plate 152. In some embodiments, gasket 162 is provided by a sealing material coupled to and / or integrally formed with movable base plate 152. For example, gasket 162 may include a sealing material (e.g., silicone) overmolded onto movable base plate 152. Gasket 162 may form a liquid-tight seal between movable base plate 152 and elongated body 112. For example, when movable base plate 152 translates within internal volume 118 along longitudinal axis 111, the outer diameter of gasket 162 may maintain sealing contact with inner surface 122 of sidewall 120. In some embodiments, movable base plate 152 may include one or more gaskets 162, e.g., two or more gaskets 162, e.g., axially spaced apart. See, for example Figures 33-38 The gasket 162 may have different functions, such as a gasket 162 for sealing and a gasket 162 for redundancy or stability of the movable base plate 152 within the elongated body 112. In some embodiments, the inner diameter of the gasket 162 is approximately equal to or slightly smaller than the diameter of the channel 164 of the sealing portion 160, thereby providing a firm retention of the gasket 162 on the sealing portion 164. When installed on the sealing portion 160 in a tensioned state, the outer diameter of the gasket 162 is slightly larger than the inner diameter (e.g., the bore diameter) of the elongated body 112, such that bending and compression of the gasket 162 allows the base plate 152 to slide smoothly along the length of the elongated body 112 in a continuous sealing contact. In some embodiments, the movable base plate 152 does not include a separate gasket 162. Instead, the function of the gasket 162 is provided by the structure of the movable base plate 152. For example, the movable base plate 152 may include a wiper or other interference feature for providing a seal between the movable base plate 152 and the elongated body 112.

[0024] In some embodiments, a gasket 162 closer to the top surface 168 of the base plate 152 may be provided to scrape nutrients upward along the side of the elongated body 112. For example, as the base plate 152 slides along the longitudinal axis 111, the gasket 162 may detach solids and semi-solids (e.g., cream) from the inner surface 122 and transport and / or slide the detached solids and semi-solids toward the open end 116. In some embodiments, the solids and semi-solids may be or include cream, formulated foods, crumbs, or combinations thereof. In some embodiments, the plurality of gaskets 152 may have different cross-sectional shapes. The gasket 152 closer to the inclined surface 168 may have a generally flat profile on its upper surface to prevent liquid from pooling at the top of the gasket 152 between the inclined surface 168 and the elongated body 112. In some aspects, the gasket 152 closer to the recess 153 may include a vent (e.g., between gasket 18 and channel 19) to prevent a vacuum from forming between the two gaskets 18.

[0025] refer to Figures 1-2 and Figure 9 During the nutrient collection process (e.g., milk collection process), a movable base plate 152 can be positioned at the first end 114 of the elongated body 112. For example, a mother or other mammal can transfer or express nutrients (e.g., milk) into the collection container 100 via, for example, a collection device 134. Referring now... Figures 3-4 According to some embodiments, the collection container 100 can be coupled to a syringe 186 (e.g., an enteral feeding syringe) or other transfer device to transfer collected nutrients (e.g., human breast milk (HBM)) from the containing volume 150 of the collection container 100. For example, the cap 130 may provide a connector 183 configured to fluidly connect the syringe body 190 to the containing volume 150 of the collection container 100. Reference Figure 4 When the syringe plunger 192 is withdrawn (e.g., in direction 194) to create a vacuum within the syringe body 190 to transfer HBM from container 100 into the syringe body 190, the suction pressure of the syringe 186 further induces sufficient suction to move the movable base plate 152 of container 100 upward toward a first end of elongated body 12 (e.g., in direction 196). In doing so, gasket 162 is able to scrape the inner wall of elongated body 112 to push any nutrients adhering to the inner surface 122 of the inner wall in direction 196 (e.g., upward, toward cap 130 and into connector 183). Advantageously, according to some embodiments, nutrient saving can be improved by scraping the inner wall with sealing portion 160 as the movable base plate 152 moves upward by suction, since little or no nutrients can adhere to the inner wall of elongated body 112 below the current position of movable base plate 152.

[0026] refer to Figures 5 to 6 According to some embodiments, the nutrient collection system 10 includes a second variable-volume container 300. The second variable-volume container 300 may include some or all of the features and functions of the collection container 100. For example, the second variable-volume container 300 may include a base plate 352 slidably mounted within the internal volume 318 of a second elongated member 312. In some embodiments, the second variable-volume container 300 is a storage device configured to have a volume greater than that of the collection container 100. For example, the second variable-volume container 300 may store nutrients from multiple milking processes. In some embodiments, the base plate 352 of the second variable-volume container 300 may initially be located near the open end 316. (See reference...) Figure 6 When the syringe 186 is connected to the cap 330 of the second variable volume container 300 and the plunger 192 is actuated (e.g., pushed in a direction 198 opposite to direction 194) to force the contents of the syringe body 190 into the receiving volume 350 of the second variable volume container 300, the second base plate 352 is pushed against the first end 314 of the second elongated body 312.

[0027] refer to Figures 7 to 9 The syringe 186 can be connected to a second variable-volume container and draw a certain amount of nutrients from the second variable-volume container 300. In some embodiments, the nutrients are compared with a reference... Figure 4 The nutrients are drawn into syringe 186 in a manner similar to that described above. In some embodiments, syringe 186 containing the collected nutrients is configured to be coupled to an enteral feeding pump, and the collected nutrients are ejected from syringe 186 into an enteral feeding tube. In some embodiments, nutrient collection system 10 may include a plurality of collection containers 100. Collection containers 100 may deposit liquid nutrients directly into a second variable-volume container 300. In some embodiments, base plate 152 is initially located near the first end 114. A plunger rod 170 may be inserted into the internal volume 118 and engage base plate 152, allowing base plate 152 to slide in a direction 171 toward cap 130. In some embodiments, direction 171 is parallel to longitudinal axis 111.

[0028] See Figures 10-11The container 100 may be located on a supporting surface (e.g., a table, countertop, flat surface, floor, etc.). A user can grasp the syringe body 190 of the syringe 186 and pull the syringe plunger 192 in a direction away from the containing volume 150, thereby drawing the contents of the storage volume 150 into the syringe body 190. In some embodiments, the collection container 100 may be positioned such that the cap 130 is raised above the containing volume 150 under gravity. In some embodiments, the plunger rod 170 may slide the base plate 152 toward the cap 130, allowing the collection container to expel gas trapped within the containing volume 150 through the fluid port 131 of the cap 130.

[0029] refer to Figures 16-18 The plunger rod 170 is configured to engage the base plate 152 and allow the base plate 152 to slide in a direction 171 toward the cover 130. The plunger rod 170 includes a body 172 spanning between a distal end 173 and a proximal end 174. The distal end 173 may mate with a receiving portion 153 (e.g., a recess, cavity, blind hole, threaded hole, etc.) disposed on the base plate 152. In some embodiments, the proximal end 174 includes a handle or knob 175 that can be gripped by a user. The body 172 may include a hollow portion (e.g., a hollow cylindrical portion) spanning at least a portion of the length of the body 172. In some embodiments, the proximal end 174 has a first opening 176, and the distal end 173 has a second opening 177. In some embodiments, the first opening 176 and the second opening 177 are in fluid communication. In some embodiments, the body 172 includes a plurality of thumb grip portions 178 (e.g., recesses, depressions, flanges, etc.) providing a surface on which a user can apply force in direction 171 to push the plunger rod and slide the base plate 152 along the longitudinal axis 111 of the elongated member 112. In some embodiments, the body 172 has a plurality of holes 179 circumferentially spaced around the longitudinal axis of the plunger rod 170. In some embodiments, the plurality of holes are in fluid communication with a first opening 176 and / or a second opening 177.

[0030] In some embodiments, a plunger rod 170 may be provided for use with the collection container 100. The plunger rod 170 may be adapted to engage with the outward-facing surface of the movable base plate 152, for example, to push the movable base plate 152 toward the cover 130 without using the suction force described above. For example, the plunger rod 170 may have a contact surface at its distal end 173 adapted to engage with the movable base plate 152. The movable base plate 152 may have a recess 153 or opening on its outward-facing surface, which is configured to receive the contact surface of the plunger rod 170. When the distal end 173 of the plunger 170 is inserted into the recess 153, a user may push the plunger rod 170 toward the second end 166 of the elongated body 112, causing the movable base plate 152 to move toward the second end 116. In some embodiments, the diameter of the contact surface of the distal end 173 may be slightly smaller than the diameter of the movable base plate 16, for example, about 50% to about 100% of the diameter of the movable base plate 152.

[0031] In some embodiments, the plunger rod 170 can be easily inserted into the recess 153 and can provide enhanced stability to the movable base plate 152 when pushed through the elongated body 112, for example, by uniformly pushing the movable base plate 152 along the longitudinal axis 111 rather than unevenly pushing one radial side of the movable base plate 152 forward; this can also be referred to as "tilting" of the movable base plate 152. Furthermore, having a contact surface at the distal end 173 that is approximately the same size as the movable base plate 152 can also prevent tilting by preventing the plunger rod 170 from moving left or right. The inventors have found that tilting of the movable base plate 152 can increase fluid leakage from the container 100 between the elongated body 112 and the movable base plate 152. Furthermore, tilting of the movable base plate 152 can lead to increased friction when the movable base plate 152 is pushed toward the cap 130, increasing the difficulty of user operation and potentially causing user frustration and misuse.

[0032] refer to Figures 20-21 The user can grasp the flange or lip 115 located at the first end 114 of the elongated body 112 and apply a clamping force or gripping force between the lip 115 and the first pair of thumb grips 178 (shown as thumb grips 178A). Reference Figure 21 The base plate 165 has already moved (e.g., slid) within the internal volume 118, and the user can apply a pinching or clamping force between the lip 115 and the second pair of thumb grips 178B. The pair of thumb grips 178B can be located at similar points along the length of the plunger rod 170 on opposite sides of the plunger rod 170. In some embodiments, the user can apply a clamping or holding force between the lip 115 and the knob 175 to allow the base plate 152 to slide along the longitudinal axis 111 and contact the cover 130. Referring now... Figures 19-21The plunger rod 270 includes a knob 175 having an outer diameter and a recess 272 extending circumferentially along the peripheral edge of the knob 175. The plunger rod 270 may include some or all of the features and functions of the plunger rod 170. Similarly, the plunger rod 270 may include some or all of the features and functions of the plunger rod 170. In some embodiments, the knob includes defining a plurality of recesses 272 having a radius of curvature smaller than the total outer diameter of the knob 175.

[0033] refer to Figure 15 and 23 -4, the cover 130 may have an inclined profile 135, which slopes downward or at an angle from the fluid port 131 and the connector 183 to the elongated body connector 142. Figure 17 A cross-sectional view of the cover 130 and a side view of the elongated body 112 are shown, wherein a movable base plate 152 is pulled to its first end 114. In some embodiments, the cover 130 provides a fluid port 131 and a cap 133 configured to selectively seal the fluid port 131. The fluid port 131 may be or include a connector portion 183. For example, the connector portion 183 may be a reverse Luer lock (e.g., ENfit). TM A lock or slip-lock coupling facilitates fluid connection between the containing volume 150 and the syringe 186. In some embodiments, the cap 130 may have a sloped surface 135 and may provide a top plate for the containing volume 150. In some embodiments, the sloped surface 135 may be conical in shape. In some embodiments, a fluid port 131 may provide a flow path between the internal volume 118 and the exterior of the container 100, and allow the contents of the elongated body 112 to flow through the cap 130.

[0034] refer to Figures 15-17 The movable base plate 152 may have an inwardly facing surface 168 disposed within the elongated body 112, which defines the base plate containing the volume 150. The inwardly facing surface 168 may have a convex profile (see...). Figure 27 and Figure 31This reduces or eliminates the "dead zone" between the inward-facing surface 168 and the inclined surface 135 of the cap 130. For example, the angle or pitch of the inward-facing surface 168 can be approximately equal to the angle or pitch of the inclined surface 135, i.e., equal to the angle of the inclined surface 135 or within about 1-2 degrees of the angle of the inclined surface 135. Similarly, any surface profile features of the inclined surface 135 can be complementaryly matched to the inward-facing surface 168 to further reduce the dead zone. The inventors have found that by matching or substantially matching the spacing between the inward-facing surface 168 and the inclined surface 135, the amount of HBM lost during transfer from the elongated body 112 to the syringe 186 or other container can be minimized or almost eliminated, thereby improving the efficiency of HBM transfer to increase the amount of HBM that can be supplied to the patient. The angles of the inclined surface 135 and the inward-facing surface 168 can range from about 1 degree to about 5 degrees, for example from about 2 degrees to about 4 degrees, for example about 3 degrees. In some embodiments, the angle of the inward-facing surface 168 is greater than 5 degrees. The inventors have discovered that an angle of approximately 3 degrees can result in a significant reduction in the volume of fluid remaining in the container (e.g., breast milk, a fluid having both water and lipid properties). Comparative data between prototype bottles with inclines of 3, 5, and 7 degrees on both the inward-facing surface 168 and the inclined surface 135 are shown in Table 1 below.

[0035]

[0036] Table 1 - Comparison data between containers with various tilt angles In some aspects of the invention, the inclined surface 135 of the cap 130 may have a smooth surface finish to reduce lipid adhesion to the surface of the syringe. For example, an A2 polished surface finish may be used. Similarly, the inclined surface 62 of the movable base plate 16 may be provided with a surface finish configured to reduce lipid adhesion, such as an A2 polished surface finish.

[0037] The inventors have discovered that, compared to other surface finishes, the A2 polished surface finish exhibits reduced nutrient loss and adhesion between nutrients and the inclined surface 62. Table 2 below shows the test data and average nutrient loss for various surface finishes, in grams. The following surface finishes on polypropylene were tested: A2, A3, B2, B3, T1, and T2. The nutrients sampled were latex. Each sample was tested ten times.

[0038]

[0039] Table 2 - Comparative data of containers with various surface finishes In another example, where a container with both the inward-facing surface 168 and the inclined surface 135 having a 3-degree inclination was used for testing, the volume remaining in the container for ten samples was measured, as shown in Table 3. The average volume remaining in the container for the ten samples was 0.45 mL.

[0040]

[0041] Table 3 – Comparison of Remaining Volume Container 100 was further compared with competing containers using a syringe to transfer nutrient solution from the container. Container 100 has a sloping surface 168 at approximately 3 degrees and a movable base 152 with two gaskets 164. Competing containers consist of 8-ounce polypropylene bottles with flat-head nuts. Ten test samples were performed for each of containers 100 and the competing containers. The results are shown in... Figure 60 middle.

[0042] Overall, comparative tests showed that the average volume remaining in container 100 was 0.23 mL, while the average volume remaining in competing containers was approximately 0.78 mL. In other words, the competing containers retained three times the amount of nutrients compared to the container of the present invention. In other words, the container of the present invention demonstrates a 200% improvement in reducing the amount of nutrients remaining in the container.

[0043] refer to Figures 25 to 26 , Figures 48 to 55 According to some embodiments, the base plate 152 includes a sealing portion 160 having a wiper 141 (e.g., wiper lip, wiper flange, wiper blade, etc.) extending circumferentially around one side of the base plate 152. In some embodiments, the wiper 141 is forward-facing as the base plate slides from a first end 114 to a second end 116 of the elongated body 112. For example, the furthest portion of the wiper 141 may extend radially outward and toward the surface 168. In some embodiments, the base plate 152 is a single body.

[0044] refer to Figures 25-27 , Figures 29-32 and Figures 39-55According to some embodiments, the base plate 152 includes a skirt 180. In some embodiments, the skirt 180 has axial ribs 155. The axial ribs 155 can project radially from the outer peripheral surface 157 of the skirt 180 and extend in an axial direction. The skirt 180 may also include a plurality of legs 159. The legs 159 may be annular. For example, the plurality of legs 159 may define an inner diameter and an outer diameter. In some embodiments, the plurality of legs 159 may be circumferentially spaced around a central axis 161 of the base plate 152. In some embodiments, the skirt 180 provides a thrust surface for centering and / or aligning the base plate 152 within the internal volume 118 when an axial force is applied to the receiving portion 153 via the plunger rod 170. This helps prevent torsional or pivoting movement of the base plate 152 within the internal volume 118 relative to the longitudinal axis 111 of the container 100. In some embodiments, the skirt 180 includes a plurality of cutouts 238 between the legs 159. In some embodiments, the bottom edge 232 of the leg 159 defines the bottommost edge of the skirt 80. In some embodiments, at least a portion of the inner and outer surfaces of the leg 159 are aligned with the outer surface of the skirt 80. In some embodiments, the leg 159 includes a foot 240.

[0045] refer to Figures 23-24 The inner surface 122 of the opening 202 at the second end 116 has a chamfer or bevel 137. The cover 130 may include a boss 139 projecting from the beveled surface 135. In some embodiments, the boss 139 may extend into the opening at the second end 116 of the elongated member 112. In some embodiments, when the base plate 152 contacts the cover 130, the boss 139 may occupy a space 117 defined between the base plate 152 and the inner wall 122. In some embodiments, when the cover 130 is attached to the second end 116 of the elongated member 112, the boss 139 may cover the bevel 137.

[0046] refer to Figure 28The first end 116 of the elongated body 212 may include a flange or lip 115 extending circumferentially from the underside of the elongated body 112. The flange or lip 115 may be generally flat, for example, to provide a surface for placement or resting and / or to provide an ergonomic surface for engagement of one or more fingers when the plunger 170 is pressed. The flange or lip 115 may be generally circular or annular, having a flat portion 119 to prevent the container 100 from rolling when tipped over. In some aspects, more than one flat segment 119 may be provided around the circumference of the flange or lip 115. In some embodiments, the profile of the flange or lip 115 is polygonal (e.g., hexagonal, octagonal, pentagonal, etc.). In some embodiments, a groove 121 may be provided along the bottom surface 123 of the flange or lip 115, for example, on a surface on which the elongated body 112 may be placed. The groove 121 can serve as a vent to prevent the formation of a vacuum or suction between the flange or lip 115 and the surface where the elongated body 112 is located. The groove 121 can be provided at any point in the radial direction surrounding the flange 115, for example, along a portion of the flat section 119, such as... Figure 28 As shown. Reference Figure 17 In some embodiments, a lip 115 extends radially inward from the inner surface of the elongated body 112 and into the internal volume 118. An inner edge 206 of the lip 115 may define an opening 214. A portion 210 of the inner edge 206 of the lip 115 extends axially into the internal volume 118, forming a shoulder 212, such that a recess 216 is formed between the shoulder 212 and the inner surface 122 of the elongated body 112. The recess 216 may extend circumferentially around the elongated body 112. In some embodiments, when the base plate 152 is in its lowest position, a portion of the bottom surface 230 and / or edge 232 of the base plate 152 is received within the recess 216.

[0047] refer to Figures 33-35The gasket 162 may have an undulating side profile. For example, the gasket 162 may be an X-shaped gasket with a double-ridged side profile having an upper convex portion and a lower convex portion or "ridge" and a recess therebetween. However, it should be understood that the gasket 162 may have any geometry, such as a surface profile, that provides a seal between the movable base plate 152 and the elongated body 112 and scrapes nutrients along the elongated body 112 while minimizing frictional interference between the movable base plate 152 and the elongated body 112. Each gasket 162 may be formed of an elastic material configured to be compressed between the movable base plate 152 and the elongated body 112. In this way, any nutrients adhering or stuck along the elongated body 112 can be scraped off the side of the container and towards the fluid port 131 and the connector 183 by the gasket 162 and the movable base plate 152. By providing a plurality of washers 162 spaced axially along the movable base plate 152, for example, Figures 33-35 The two washers shown provide an increased contact surface area between the elongated body 112 and the movable base plate 152 to enhance upward sweeping of nutrients toward the cap 130 and connector 183 when the plunger rod 170 is compressed, and to allow the movable base plate 152 to move smoothly in the direction of the longitudinal axis 111 of the elongated body 112.

[0048] Reference Figures 34 to 38 The recess 153 of the movable base plate 152 may have an alignment feature 163 extending from the recess 153. Furthermore, the distal end 173 of the plunger rod 370 may have a complementary alignment feature 165. For example, the alignment feature 163 may include a protruding structure, such as a stud, projecting from the recess 153. The protruding structure may be substantially centered on the central axis 161 of the movable base plate 152. The complementary alignment feature 165 of the plunger rod 370 may be a recess or other concave structure in the contact surface of the distal end 173, configured to receive the protruding structure. The complementary alignment feature 165 of the plunger rod 370 may be substantially centered around the central axis 161 of the plunger rod 370. In this way, when the distal end 173 of the plunger rod 370 is inserted into the recess 153 of the movable base plate 152, alignment features 163 and 165 can improve the axial alignment of the movable base plate 352 and the plunger rod 370 along a common longitudinal axis.

[0049] refer to Figures 36 to 38The plunger rod 370 may have an elongated plunger body 172 with ergonomic surface features. For example, one or more concave recesses 181 may be formed around the circumference of the elongated plunger body 172. The concave recesses 181 may have curved surfaces configured to receive a user's fingers, such as a user's thumb. The elongated plunger body 80 may have a plurality of concave recesses 181 around the circumference of the plunger body 80. For example, in some aspects, four concave recesses 181 may be provided around the circumference of the elongated plunger body 172. Additionally or alternatively, the elongated plunger body 172 may include a plurality of concave recesses 181 along the length of the plunger body 172. For example, at least two concave recesses 181 may be arranged adjacent to each other along the length of the elongated body 172. The curved concave recesses 181 may enhance the ergonomics of a user pressing the plunger 370 into the elongated body 112 of the container 100. Furthermore, by providing a plurality of curved concave recesses 181 around the circumference and / or length of the plunger body 172, the user can ergonomically position their fingers in the most comfortable and ergonomic position around the circumference and length of the plunger body 172.

[0050] like Figure 22 As shown, cap 130 may include connector 183. In some embodiments, connector 183 is an intestinal connector configured to engage with a complementary adapter for fluid transfer. The connector may optionally include a convex connection feature extending upward from the cap. In some embodiments, cap 133 is configured to seal the adapter when not in use. Cap 133 may be hingedly engaged with cap 130 and may have a snap-fit ​​engagement to close and seal connector 183. However, it should be understood that any suitable connection arrangement may be used.

[0051] refer to Figure 56 According to some embodiments, a process 5600 for preparing nutrients and providing nutrients to a recipient is shown. According to some embodiments, process 5600 can be performed using a nutrient collection and distribution system 10. In some embodiments, process 5600 begins at step 5602.

[0052] In step 5602, according to some embodiments, process 5600 includes extruding nutrients into a collection container. For example, a mammal may express a certain amount of milk into the containing volume 150 of container 100. In some embodiments, the mammal may pump HBM directly or otherwise provide it into the containing volume 150. In some embodiments, the extruded nutrients are extracted or received by a lactation pump head 132 coupled to the containing volume 150. In some embodiments, the extruded nutrients may be provided through a cylinder 500 having a filter 520 between the lactation pump head 132 and the containing volume 150 of collection container 100. In some embodiments, process 5600 continues to step 5604.

[0053] In step 5604, according to some embodiments, process 5600 may include attaching a cap to the collection container. For example, a user may attach the cap 130 to a second end 116 of the collection container 100. In some embodiments, the user may first remove the lactation pump head 132 from the second end 116 and then attach the cap to the second end 116 of the collection container. In some embodiments, process 5600 continues with step 5604.

[0054] In step 5606, according to some embodiments, process 5600 may include attaching a transfer syringe to a cap. For example, a user may attach syringe 186 to cap 130 of receiving system 100. In some embodiments, syringe 186 is configured to be coupled to an enteral supply pump or injection pump. In some embodiments, the syringe may draw some or all of the nutrients from the containing volume 150 of collection container 100. In some embodiments, movable base plate 152 may move from a first end 114 to a second end 116 within internal volume 118. In some embodiments, process 5600 proceeds to step 5608.

[0055] In step 5608, according to some embodiments, process 5600 may include transferring nutrients from the transfer syringe to a second container. For example, a user may transfer nutrients from the transfer syringe 186 to a second variable-volume container 300. In some embodiments, the nutrients may be stored within the second variable-volume container 300. In some embodiments, process 5600 continues to step 5610.

[0056] In step 5610, according to some embodiments, process 5600 may include dispensing nutrients into one or more transfer syringes. For example, a user may draw nutrients from a second container 300 into one or more syringes 186.

[0057] In step 5612, according to some embodiments, process 5600 may include administering nutrients to the patient. For example, the user may administer nutrients directly (e.g., by spraying the nutrients directly into the patient's mouth or other orifice) or via an enteral feeding device or apparatus. In some embodiments, nutrients are administered to the patient.

[0058] refer to Figure 57 According to some embodiments, a process 5700 for preparing nutrients and providing nutrients to a recipient is shown. According to some embodiments, process 5700 can be performed using a nutrient collection and distribution system 10. In some embodiments, process 5700 begins at step 5702.

[0059] In step 5702, according to some embodiments, process 5700 includes removing the cap from the dispensing container and / or opening the cap on the collection container. For example, a user may remove the cap 330 from the second variable volume container 300 and unseal the fluid port 131. For example, a user may remove the cap 133 to expose the fluid port 131. In some embodiments, process 5700 proceeds to step 5702.

[0060] In step 5704, according to some embodiments, process 5700 includes attaching a plunger rod to a movable base plate and pushing the milk into the dispensing container. For example, a user can insert the plunger rod 170 into the receiving portion 153 and apply pressure to one or more of the plurality of concave recesses 181, thumb grips 178, and knobs 175. In some embodiments, the user can engage pairs of thumb grips 178A and / or 178B and move the base plate 152 in a direction 171 toward the cap 130. See, for example... Figures 20-21 In some implementations, process 5700 proceeds to step 5706.

[0061] In step 5706, according to some embodiments, process 5700 includes fortifying nutrients. In some embodiments, process 5700 continues by reattaching the cap, closing the fluid port, and agitating the container (step 5708), aspirating gas from the container via a plunger tool (step 5710), drawing a certain amount of nutrients into a syringe (step 5712), placing the syringe in an enteral delivery pump (step 5714), and / or administering the nutrients to the recipient (5716).

[0062] refer to Figure 58According to some embodiments, a process 5800 for preparing nutrients and providing nutrients to a recipient is shown. According to some embodiments, process 5800 can be performed using a nutrient collection and dispensing system 10. In some embodiments, process 5800 includes opening the cap (step 5802), holding the container on a flat surface (step 5804), drawing the container with a syringe (step 5806), drawing the desired amount of nutrients (step 5808), replacing the cap (step 5810), and / or administering the contents of the syringe (step 5812).

[0063] refer to Figure 59 According to some embodiments, a process 5900 for preparing and distributing nutrients to a recipient is shown. According to some embodiments, process 5900 can be performed using a nutrient collection and dispensing system 10. In some embodiments, process 5900 begins with the mother pumping breast milk into a bottle (step 5902), transporting the bottle to the hospital according to hospital protocols (step 5904), attaching a plunger tool to the bottom of a base plate and pushing it upwards to actuate the movable base plate and remove gas (e.g., air) from the container (step 5906), and determining whether to dispense the fluid into a dispensing container (step 5908). If the result is "yes" in step 5918, process 5900 can continue, opening the cap and attaching a syringe (step 5918), drawing the desired amount of nutrients into the syringe (step 5920), and / or administering the syringe contents (step 5922). In some embodiments, if no in step 5918, process 5900 continues to remove the cap from the dispensing container and open the cap on the collection chamber (step 5910), push the milk from the collection container into the dispensing container using a plunger tool (step 5912), fortify the nutrients by mixing in a certain amount of fortifier (e.g., formula milk powder) (step 5914), and / or aspirate the dispensing container by opening the tip and using a syringe to draw air out through the fluid port in the cap, or by attaching the plunger tool to the bottom of the movable base plate and pushing the movable base plate against the cap to expel gas from the container's containing volume (step 5916), all according to some embodiments.

[0064] Figures 61 to 67 Another exemplary nutrient collection system 10 is provided. As described in more detail herein, the example nutrient collection system 10 utilizes a scraping tool for releasing liquids and solids from the inner surface of the collection container. Figures 67 to 67 The nutrient collection system 10 is similar to the one referenced in this article. Figures 1 to 60 and Figures 68 to 79 Other collection systems are shown. Therefore, refer to... Figures 61-67 The implementation methods provided herein are used for Figures 1-60 and Figures 68-79The reference numerals used in the embodiments shown are similar to those used in the accompanying drawings. Features in any other embodiments disclosed herein are contemplated to be included. Figures 61-67 The implementation method disclosed herein.

[0065] Figure 61 and Figure 62 A side view of an exemplary collection container 400 is provided. Similar to the collection containers described herein, the collection container 400 includes an elongated body 412 extending between a first end 414 (bottom) and a second end 416 (top). Figure 61 and Figure 62 As provided, the first end 414 of the collection container 400 may be an open end or an openable end of the collection container 400 to allow transfer of nutrients contained within the internal volume 418 of the collection container 400. In some embodiments, the first end 414 is configured to receive a cap or lid to seal or otherwise close the collection container 400. In some embodiments, the first end 414 of the collection container 400 includes a coupling feature for coupling the first end 414 of the collection container 400 to a lid or nutrient collection device (e.g., a breast milk collection device). For example, in some embodiments, the first end 414 of the collection container 400 may be configured to couple to a breast flange that couples to a breast pump for collecting human breast milk. The coupling feature may include a threaded surface, a snap-fit, a press-fit, a lock, a clamp, or other features for coupling the first end 414 to a lid and / or a nutrient collection device.

[0066] like Figure 61 and Figure 62 As provided herein, the collection container 400 includes an inner wall 420 defining an internal containing volume 418 of the collection container 400. As described herein, in some embodiments, the internal containing volume 418 is configured to retain nutrients (e.g., HBM).

[0067] Figure 61 A side view of a collection container 400 is provided, in which a certain volume of nutrients is contained within an internal volume 418. (See attached image.) Figure 62 As provided herein, and as described herein, in some embodiments, when the contained nutrients are dispensed from the collection container 400, both liquid and solid portions of the nutrients may adhere to the inner wall 420 of the collection container 400. It is important that these residual portions of the nutrients be collected as much as possible, because nutrient solids (e.g., lipids contained in human breast milk) will adhere to the inner wall of the collection container 400. As described herein, a scraping device such as a scraper 450 can be used to remove the adhered portions of the nutrients from the inner wall 420 of the container 400, thereby helping to ensure that as much nutrition as possible (including the typically most nutrient-rich nutrient solids) is removed from the container and provided to the patient.

[0068] Figure 63 A side perspective view of an exemplary scraper 450 is provided. The scraper 450 is sized and configured to be received within and movable within the internal volume 418 of the collection container 400. Figure 63 As described herein, the scraper 450 includes an elongated body 452 having a central inner cavity 454 extending therethrough. The scraper 450 includes wings 480 extending radially from the elongated body 452 for wiping or scraping the inner wall 420 of the collection container 400 to remove adhering nutrients.

[0069] In some embodiments, the rotation and / or longitudinal movement of the scraper 450 within the internal volume 418 of the collection container 400 causes the wings 480 to contact the inner wall 420 and detach nutrient contents (both fluid and solid) adhering to the inner wall 420 of the collection container 400. As a result, nutrients in the collection container 400, including the detached nutrients, can be collected from the collection container 400. This minimizes nutrient loss because little or no nutrients can adhere to the inner wall 420 of the collection container 400 and can be successfully removed.

[0070] like Figure 63 As provided, the elongated body 452 of the scraper 450 extends between a proximal end 456 and a distal end 458. In some embodiments, such as Figure 63 As shown, the wing 480 is located near the distal end 458 of the elongated body 452. It is conceivable that the wing 480 can be positioned anywhere along and around the elongated body 452 to facilitate the removal of nutrients from the inner wall 420 of the collection container 400.

[0071] like Figure 63 As described above, in some embodiments, the scraper 450 includes two wings 480 extending radially from the elongated body 452. For example... Figure 63 Provided herein, each of the wings 480 extends from opposite sides of the elongated body 452. In some embodiments, the scraper 450 may include more than two wings 480 extending radially from the elongated body 452 of the scraper 450 and circumferentially spaced around the elongated body 452. In some embodiments, the scraper 450 includes a plurality of wings 480 symmetrically spaced around the elongated body 452. In some embodiments, the scraper 450 includes a plurality of wings 480 asymmetrically spaced around the elongated body 452. In some embodiments, the wings 480 are arranged around the elongated body 452 with complementary opposite wings 480. In some embodiments, such as Figure 63 As provided, the wing 480 is longitudinally aligned along the elongated body 452. In other embodiments, the wing 480 may be offset or longitudinally spaced from adjacent wing 480s along the elongated body 452.

[0072] like Figure 63 As shown, in some embodiments, each wing 480 has a corresponding size and shape. In other embodiments, the size, shape, and position of the wing 480 may vary around and along the elongated body 452. In some embodiments, when the scraper 450 includes more than one wing 480, the elongated body 452 is centered within the internal volume 418 of the collection container 400 when the scraper 450 is received within the internal volume 418 of the collection container 400.

[0073] like Figure 63 As shown, the wing 480 includes a side edge 482, wherein the distance (D1) between the side edge 482 of the wing 480 and the elongated body 452 (e.g., the outer surface of the elongated body 452) corresponds to the distance between the elongated body 452 (e.g., the outer surface of the elongated body 452) and the inner wall 420 of the collection container 400 when the scraper 450 is received within the internal volume 418 of the collection container 400. In some embodiments, the distance (D1) between the side edge 482 of the wing 480 and the elongated body 452 is greater than the distance between the elongated body 452 and the inner wall 420 of the collection container 400. As a result, when the scraper 450 is received within the internal volume 418, the wing 480 is pressed against the inner wall 420 of the collection container 400. When the wing 480 presses against the inner wall 420 of the collection container 400, the interference between the side edge 482 of the wing 480 and the inner wall 420 causes any nutrients, including solids, adhering to the inner wall 420 of the collection container 400 to detach. In some embodiments, the interference between the wing 480 and the inner wall 420 causes the wing 480 to bend / flex, such that the front surface 490 and / or the opposing rear surface 492 of the wing 480 contact the inner wall 420. As a result, the front surface 490 and the opposing rear surface 492 of the wing also serve to detach nutrients adhering to the inner wall 420 of the collection container 400.

[0074] like Figure 63 As shown, the wing 480 includes a bottom edge 484 extending between the outer surface of the elongated body 452 and the side edges 482. In some embodiments, the bottom edge 484 extends at an acute angle toward the proximal end 456 of the scraper 450 relative to the outer surface of the elongated body 452. In some embodiments, the bottom edge 484 has a shape corresponding to the shape of the bottom inner wall 420 of the collection container 400. Therefore, the bottom edge 484 of the wing 480 is capable of detaching any nutrients adhering to the bottom inner wall 420 of the collection container 400. Figure 63 As provided, the bottom edge 484 is aligned with the bottom surface 460 of the elongated body 452. This allows the entire bottom edge / surface of the scraper 450 to align with the bottom inner wall 420 of the collection container 400, thereby maximizing the discharge of nutrients.

[0075] In some embodiments, the wing 480 includes a top edge 486 that extends from / between the side edge 482 of the wing 480 and the outer surface of the elongated portion 452. In some embodiments, the top edge 486 extends at an acute angle toward the distal end 458 of the scraper 450 relative to the outer surface of the elongated body 452. In some embodiments, such as Figure 63 As explained, the axial length of the top edge 486 (measured along the longitudinal axis of the elongated body 452 / scraper 450) is greater than the axial length of the bottom edge 484. Alternatively, the axial length of the bottom edge 484 may be greater than the axial length of the top edge 48.

[0076] like Figure 63 As provided, the wing 480 includes an end surface 488 defining an edge of the wing 480. The end surface 488 may define an axial and / or outer periphery or surface of the wing 480. In some embodiments, when the scraper 450 is positioned within the collection container 400, at least a portion of the end surface 488 abuts against the inner wall 420 of the receiving collection container 400. In some embodiments, the end surface 488 of the wing 480 extends perpendicular to the front surface 490 and / or the opposing rear surface 492 of the wing 480. In some embodiments, the end surface 488 of the wing 480 extends at an angle relative to the front surface 490 and the opposing rear surface 492 of the wing 480.

[0077] In some embodiments, the end face 488 of the wing 480 includes a groove or other surface treatment that provides a contact surface that increases friction between the wing 480 and the inner wall 420 of the collection container 400 as the scraper 450 moves within the collection container 400. This groove or surface treatment facilitates the removal of the contents of the collection container 400 from the inner wall 420.

[0078] In some embodiments, the wings 480 and / or the elongated body 452 of the scraper 450 are formed of a material capable of undergoing sterilization procedures. For example, the wings 480 may be formed of silicone or any other suitable material capable of being sterilized. For example, in some embodiments, the scraper 450 may be sterilized to come into contact with HBM and to prevent HBM contamination before feeding a newborn.

[0079] In some embodiments, the scraper 450 includes a connecting mechanism 455 at the proximal end 456 of the elongated body 452, such as Figure 64 and Figure 66As shown in the diagram. The coupling mechanism 455 is configured to removably couple the scraper 450 to the collection device. The coupling mechanism 455 may include a threaded connection, snap-fit, press-fit, Luer connection, or any other connection known in the art for forming a liquid-tight seal / connection between the scraper 450 and the collection device to remove nutrients from the collection container 400 via the scraper 450. As described herein, the collection device is adapted to extract / aspirate contents from the collection container 400 via the scraper 450. In some embodiments, such as Figure 64 and Figure 66 As shown, the collection device includes a syringe 20. The syringe 20 can be removably coupled to a coupling mechanism 455 and is used to aspirate the contents of the collection container 400, including nutrients (e.g., HBM and corresponding lipids) detached from the inner wall 420 of the collection container 400, and enter the barrel 22 of the syringe 20. For example, when the plunger 24 of the syringe 20 is withdrawn within the syringe 20, a vacuum is created within the barrel 22, thereby drawing nutrients from the collection container 400 through the central cavity 454 of the scraper 450 and into the barrel 22 of the syringe 20. In some embodiments, such as Figure 65 As shown, nutrients can also be poured out through the opening 414 of the collection container 400.

[0080] refer to Figure 67 A method (4000) is provided for removing contents from the interior of a collection container 400 using a scraper 450. A collection container 400 is provided comprising contents (e.g., nutrients). For example, in some embodiments, HBM is pumped directly into the collection container 400 (step 4002). A lid may be attached to a coupling mechanism disposed at a first end 414 of the collection container 400 to secure the contents of the collection container 400 for transport and / or to prevent contamination (step 4004). When a user is ready to dispense nutrients from the collection container 400, the lid is removed, thereby providing an open first end 414 of the collection container 400 (step 4006).

[0081] The scraper 450 is then inserted into the open first end 414 of the collection container 400 containing nutrients (step 4008). In some embodiments, if the scraper 450 and / or is near the open first end 414 of the collection container 400, a shroud is provided around the elongated body 452 to prevent accidental spillage or contamination of the nutrients contained in the internal volume 418.

[0082] The scraper 450 then moves rotatably and / or axially within the internal volume 418 of the collection container 400, such that the wings 480 contact the inner wall 420 of the collection container 400 (step 4010). The interference between the wings 480 and the inner wall 420 of the collection container 400 causes any nutrients and / or contents adhering to the inner wall 420 of the collection container 400 to detach. In some embodiments, the scraper 450 rotates less than 360° within the internal volume 418 of the collection container 400. In some embodiments, the scraper 450 rotates more than 360° within the internal volume 418 of the collection container 400. In some embodiments, the scraper 450 rotates in only one direction. In some embodiments, the scraper 450 rotates in both clockwise and counterclockwise directions.

[0083] The nutrients, including any detached components, are then removed from the collection container 400 (step 4012). In some embodiments, the nutrients are extracted by pouring them out of the open first end 414 of the collection container 400, such as... Figure 65 As shown. In some embodiments, nutrients may alternatively or additionally be extracted through the central cavity 454 of the scraper 450. For example, a collection device (e.g., syringe 20) is coupled to a coupling mechanism 455 located at the proximal end 456 of the elongated body 452 of the scraper 450. Suction or vacuum is then applied to the central cavity 454 of the scraper 450 via the coupling mechanism 455, causing the contents of the collection container 400 (including any contents detached from the inner wall 420) to be drawn through the central cavity 454 of the scraper 450 and into the collection device. It is conceivable that nutrients can be removed from the collection container 400 by pouring from the first end 414 of the opening and by suction through the central cavity 454 of the scraper 450; and either of these removal methods may be performed first and / or repeated.

[0084] The nutrients are then provided to a feeding device used to provide nutrition to the patient (step 4014). In some embodiments, the collection device also functions as a feeding device. The nutrients are then provided to the patient (step 4016).

[0085] refer to Figures 68-77 The nutrient containment and dispensing system 50 may also include collection and / or transfer devices, such as collection bottles or syringes, which are capable of separating or filtering lipids (i.e. fats) from the remaining fluid in human breast milk in order to concentrate the lipid content for feeding newborns.

[0086] refer to Figures 68-77 The nutrient containment and distribution system 50 may include a cylinder 500 that spans between a first end 502 and a second end 504 and defines an internal volume 506 therebetween. The cylinder 500 may have a first opening 508 at the first end 504 and a second opening 510 at the second end 504.

[0087] In some embodiments, the movable filter 520 is slidably mounted within the internal volume 506 of the cylinder 500. For example, the movable filter 520 can slide along the longitudinal axis of the internal volume 506. In some embodiments, the filter 520 divides the internal volume 506 into a first chamber 522 and a second chamber 524.

[0088] refer to Figure 69 The filter 520 may include a sealing portion 160 configured to maintain a seal with respect to the inner wall of the housing 500. For example, the sealing portion 160 may include a gasket 162. In some embodiments, the filter 520 includes a filter medium 526 configured to prevent the passage of solids and semi-solids. For example, the filter medium 526 may be a lipid filter. In some implementations, a filter plunger rod 530 is configured to engage the filter 520 and move the filter 520 within an internal volume 506, thereby adjusting the volume of the first chamber 522 and the volume of the second chamber 524.

[0089] refer to Figure 68 and Figures 70 to 71 The collection container 100 may be coupled to a second end 504 of the cylinder 500. For example, the collection container 100 may include a cap configured to fluidly connect the internal volume 506 of the cylinder 500 to a receiving volume 150 of the collection container 100. In some embodiments, the collection container 100 also includes a lactation pump head 132 coupled to a first end of the cylinder 500. (See reference...) Figure 70 Nutrient flow 542 can be guided in the direction of arrow 544. Filtered fluid 546 (e.g., filtered milk) can be collected in collection container 100.

[0090] refer to Figures 70 to 71 The cylinder 100 can receive and at least partially transfer fluid between the first opening 508 and the second opening 510. For example, when a nutrient stream (e.g., nutrients, HBM, milk, emulsified nutrients, etc.) is guided through the first opening 508 of the cylinder 500, the movable filter 520 can prevent solids and semi-solids within the nutrient stream from flowing through and entering the second chamber 524. In some embodiments, when an emulsified nutrient stream is guided through the first opening 508 of the cylinder 40, the filter 520 prevents lipids from flowing into the second chamber 524, causing lipids contained in the emulsified nutrient stream to accumulate in the first chamber 522. For example, solids and semi-solids can be or include lipids. In operation, a certain amount of lipids can accumulate in the first chamber 522, as shown by the accumulation 540. The accumulation 540 can occupy at least a portion of the volume of the first chamber 524.

[0091] refer to Figures 73-76The nutrient containment and dispensing system 50 may include a plunger rod 530. In some embodiments, the plunger rod 530 is configured to be received by a second opening 510. For example, the distal end 524 of the plunger rod 530 may pass through the opening 510 and engage a filter 520. In some embodiments, the plunger rod 530 is configured to engage the filter 520 such that the filter 520 is movable toward a first end 502 of the housing 500. In one embodiment, the plunger rod 530 includes a thumb rest 532 on the proximal end 534 of the plunger rod 530.

[0092] refer to Figures 73 to 74 and Figure 76 The nutrient containment and distribution system 50 may include a nipple attachment 536 connected to a first end 504 of the cylinder 500. In some embodiments, when the plunger rod 530 slides the filter 520 within the cylinder 500 toward the first end 508, the contents of the first chamber 522 are discharged from the cylinder 500 and enter the nipple attachment 536 or the enteral feeding tube 538 connected to the first end 502 of the cylinder 500.

[0093] refer to Figure 78 According to some embodiments, a process 7800 for preparing nutrients and providing nutrients to a recipient is shown. In some embodiments, process 7800 includes providing a nutrient stream through a filter (e.g., a lipid filter) slidably mounted within the inner bore of a cylinder (step 7802), accumulating lipids of the nutrient stream in a first chamber of the cylinder (step 7804), collecting liquid nutrients (e.g., filtered milk) of the nutrient stream in a container connected to a second end of the cylinder (step 7806), fortifying the collected liquid nutrients (step 7808), draining the accumulated lipids from the first volume by sliding the lipid filter within the cylinder (step 7810), draining the accumulated lipids into an enteral feeding tube or nipple attachment (step 7812), providing the accumulated lipids to the recipient (step 7814), and / or providing liquid nutrients to the recipient (step 7816).

[0094] refer to Figure 79 According to some embodiments, a process 7900 for preparing nutrients and providing nutrients to a recipient is shown. In some embodiments, process 7800 includes directly connecting a cylinder with an internal filter to a breast pump shield to collect fat and filter milk into a collection bottle (step 7902), feeding the fat orally or into a feeding tube when inserting a plunger (step 7904), and / or administering the liquid nutrients collected in the bottle to the recipient (step 7906).

[0095] In some embodiments, a method for preparing and providing nutrients to a recipient (e.g., method 7800) may include: providing an emulsified nutrient stream through a cylinder including a lipid filter slidably mounted within an inner bore of the cylinder; accumulating lipids contained within the emulsified nutrient stream within a first volume of the inner bore of the cylinder; and / or providing the accumulated lipids to the recipient. In some embodiments, the method includes collecting the liquid nutrient stream in a container coupled to a second end of the cylinder. In some embodiments, the method includes fortifying the liquid nutrient stream and providing the fortified liquid nutrient stream to the recipient.

[0096] For example, the syringe body or barrel 500 may have an open first end and an open second end. Between the first and second ends, a filter 42 may be disposed within the syringe body 40. The filter is configured to separate lipids in human breast milk from the rest of the fluid, such that the lipids do not pass through the filter. In this arrangement, lipids can be collected and contained within the syringe body 500, while the remaining fluid of the human breast milk passes through the filter 520. In this way, lipids can be concentrated and collected for direct feeding of newborns, thus ensuring high-calorie nutritional feeding. The syringe body 500 may be sized to contain and collect a fluid volume of up to 5 mL or 10 mL between the first end and the filter 520. However, the syringe body 500 can be formed to any desired size to collect larger or smaller volumes of lipids from human breast milk.

[0097] The filter 520 may be a filter disc whose outer peripheral shape approximately matches the cross-sectional shape of the syringe body 500, such that the filter disc is completely housed within the syringe body 500. The filter 520 can separate lipids from the remaining liquid in the HBM, for example, through microfiltration or any other suitable method. For instance, the filter 520 can separate particles by size, whereby larger lipid molecules (also known as fat globules) cannot pass through the pores of the filter and are thus contained within the syringe body 500 between the first end of the syringe body 500 and the filter 520.

[0098] exist Figures 68 to 71 In one configuration described herein, the syringe body 500 may be coupled at a first end to a breast milk collection device 134, such as the flange of a pump, and at a second end to a collection container (e.g., a bottle) 100, such that breast milk can pass through the syringe body 500 during the breast milk collection process. In another configuration, the syringe plunger 530 may be coupled to the second end of the syringe body 500, and the first end of the syringe body 500 may be coupled to an enteral feeding system 538, a bottle nipple 536 for direct feeding of newborns, or other feeding connectors. For example, Figures 74 to 75 Each shows a syringe body 500 connected to a syringe plunger 530 at the second end 502. Figure 76 A bottle nipple 136 is shown attached to the first end 502 of the syringe body 40 for direct feeding of newborns. Figure 75 A syringe body 40 connected to an enteral feeding extension kit is shown to provide nutrition to the newborn via enteral feeding from the syringe body 40.

[0099] The collection container, such as collection container 100 described above, is intended to contain any suitable volume. For example, container 10 could be a bottle configured to hold 1 ounce, 2 ounces, 4 ounces, 8 ounces, or any other suitable volume. For example, when measuring using the metric system, Figure 1 A- Figure 1 E illustrates an embodiment of a container 10 having a measuring volume of up to about 60 mL or 120 mL.

[0100] By using any one or more of the disclosed embodiments to collect and deliver HBM to newborns, fat loss in HBM can be minimized, allowing up to or more than about 96% of the fat (lipids) in the HBM collected in the collection container to be successfully transferred to the newborn. In contrast, when using conventional systems that require transferring HBM from the collection container to a syringe, and possibly including transferring the HBM to a measuring cup before transferring it to the syringe, only about 70% of the fat (lipids) in the HBM collected in the collection container is successfully transferred to the newborn. Not bound by theory, the inventors believe that the reduction in the number of containers in which HBM is transferred during feeding, and the ability to scrape lipids or fat globules from the inner wall of the collection container using the embodiments disclosed herein, could result in a significant increase in the fat (lipid) content delivered to newborns using the system of the present invention (an increase of more than 25% in fat (lipids) delivered to newborns). Furthermore, the reduction in the number of containers required for enteral feeding using the system of the present invention directly improves ease of use for nurses, breast milk processing technicians, and other care providers during enteral feeding.

[0101] As used herein with respect to numerical ranges, the terms “about,” “approximately,” “substantially,” and similar terms generally mean + / - 10% of the disclosed value. When the terms “about,” “approximately,” “substantially,” and similar terms are applied to structural features (e.g., to describe their shape, size, orientation, direction, etc.), these terms are intended to cover minor variations in the structure that may result from, for example, manufacturing or assembly processes, and are intended to have a broad meaning consistent with common and accepted usage by one of ordinary skill in the art to which the subject matter of this disclosure pertains. Therefore, these terms should be interpreted as indicating that non-substantial or insignificant modifications or alterations to the described and claimed subject matter are considered to be within the scope of this disclosure as set forth in the appended claims.

[0102] It should be noted that the term “exemplary” and its variations, as used herein to describe various implementations, are intended to indicate possible examples, representations or illustrations of possible implementations (and such terms are not intended to imply that such implementations must be unusual or the best example).

[0103] As used herein, the term "connection" and its variations refer to a direct or indirect link between two components. Such a connection can be static (e.g., permanent or fixed) or movable (e.g., removable or releasable). This connection can be achieved by directly linking two components together, or by linking two components together using a single intervening component and any additional intermediate component. If "connection" or its variations are modified by an additional term (e.g., direct connection), the general definition of "connection" provided above is modified by the simple linguistic meaning of the additional term (e.g., "direct connection" refers to the linking of two components without any separate intermediate component), resulting in a narrower definition than the general definition of "connection" provided above. Such a connection can be mechanical, electrical, or fluid.

[0104] References to the positions of elements herein (e.g., “top,” “bottom,” “up,” “down”) are used only to describe the orientation of the various elements in the accompanying drawings. It should be noted that, according to other exemplary embodiments, the orientation of different elements may be different, and such variations are intended to be covered by this disclosure.

[0105] Although the accompanying drawings and descriptions may illustrate a specific order of method steps, the order of these steps may differ from that depicted and described, unless otherwise specified above. Furthermore, two or more steps may be performed simultaneously or partially simultaneously, unless otherwise stated above.
