Title: Apparatus, device, and method for infant gavage feeding

Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application is a PCT of U.S. application Ser. No. 16/430,634, filed Jun. 4, 2019, titled “APPARATUS, DEVICE, AND METHOD FOR INFANT GAVAGE FEEDING,” which is incorporated herein by reference in its entirety. 
    
    
     BACKGROUND 
     1. Field of Invention 
     The present disclosure relates generally to the field of infant gavage feeding and, more particularly, to an apparatus, a device, and methods to allow a standard infant feeding bottle to readily to convert into a gavage feeding device for facilitating the delivery of oral fluids such as milk to an infant. 
     2. Description of the Prior Art 
     Many babies struggle to breast or bottle feed, whether due to underdeveloped sucking and swallowing reflexes from being born prematurely or being otherwise too small or weak; due to coordination difficulties; as a result of throat, esophagus, or bowel issues; or from lung or heart problems, any of which may make standard breast or bottle feeding difficult, or in some cases impossible. Without the ability to breast or bottle feed, these babies are at risk of malnourishment absent other methods of feeding. Gavage feedings, using enteral feeding tubes, are often relied upon to supplement or replace breast or bottle feeding. 
     In some cases, babies may initially be bottle fed, but may require gavage feeding after a certain amount of milk or formula has been consumed orally. The process of switching from standard bottle feeding via a nipple to gavage feeding can be cumbersome, however, and can interrupt the flow and bonding of a feeding session. Currently, to achieve this difficult transition, any milk or formula remaining in the bottle is typically transferred from the original, standard bottle to another bottle and drawn up by a syringe from the secondary bottle, after which the syringe is attached to enteral tubing to deliver the milk directly to the baby&#39;s stomach. This process is unwieldy, and often necessitates putting the baby down or enlisting the help of a second person, thereby disrupting the baby&#39;s feeding experience. 
     Milk may also be wasted in the process, as a complete transfer of the remaining milk from the original bottle to the gavage feeding device is unlikely. This milk loss is wasteful and may create difficulties in tracking the exact volume of milk consumed by the baby. When gavage feeding, for example, there is a chance that when pouring the milk to gavage there might be spillage, resulting in loss of breast milk of unknown volume, particularly when a sole nurse or caregiver attempts to hold a wriggling baby during the bottle-to-gavage transfer process. To counteract this inevitable loss, many neonatal intensive care unit (NICU) facilities prepare more milk than needed, in order to compensate for breast milk that is wasted in the enteral tubing. Some mothers produce very small amounts of milk, such that any excess milk that is being made or wasted is likely detracting from the mother and baby&#39;s supply, or such that more donor milk is used than is necessary. 
     NICU facilities must also take into account that syringes, bottles, and pumps often do not have consistent and corresponding measurements. In some cases, if not measured correctly, any milk remaining in the enteral feeding tube at the completion of gavage feeding might be kept from the baby because, per the pump fluid measurements, the feeding may appear to be completed. As a result of this measuring inconsistency, the baby may have lost a portion of milk that was needed to meet total fluid nutritional requirements. With eight feeds per day, these repeated under-measurements could deprive the baby of substantial portions of necessary fluids and caloric needs. 
     SUMMARY 
     Applicant has recognized the difficulties noted above and that there is an unmet need for an apparatus, device, and method to efficiently convert a standard infant feeding bottle from nipple-delivered milk or formula feeding to gavage feeding, while avoiding the clumsiness and waste of typical transition methods.

The infant gavage feeding apparatus  100  can include an infant feeding bottle  105 , a gavage milk delivery component  115 , a retaining ring  160 , and a cord component  125 , according to an embodiment. The infant feeding bottle  105 , for example, can be a standard or universal infant feeding bottle, which may be compatible with a variety of infant feeding nipples, depending on individual infant ages and other physiological needs. As further illustrated in the embodiment of  FIG. 1 , the nipple  120  of the infant feeding bottle  105  may be secured to the top portion  170  of the infant feeding bottle  105  in order to facilitate nipple feeding. 
       FIG. 2  illustrates a perspective view of an infant gavage feeding apparatus  100 . As illustrated in  FIG. 2 , the nipple  120  of the infant feeding bottle  105  has been removed from the top portion  170  of the infant feeding bottle  105  in order to allow attachment of the gavage milk delivery component  115  and the retaining ring  160  to the top portion  170  of the infant feeding bottle  105 . 
     As illustrated in  FIG. 4 , the gavage milk delivery component  115  can include a frustoconical portion  155  having an elongate tube portion  150  connected to and extending outwardly and distally from the frustoconical portion  155 . The elongate tube portion  150  can be positioned to connect with an enteral feeding tube  165  when positioned adjacent thereto, in order to facilitate gavage feeding, for example as further illustrated in  FIG. 4 . 
     In various embodiments, the enteral feeding tube  165  can be selected from any of a nasogastric (NG) tube, an orogastric (OG) tube, a nasoduodenal (ND) tube, a nasojejunal (NJ) tube, a gastric or gastrostomy (G) tube, a gastrojejunal (GJ) tube, a transjejunal tube, and a jejunal (J) tube, or any other enteral feeding tube as will be readily understood by one having ordinary skill in the art. In addition, in various embodiments the elongate tube portion  150  of the milk delivery component  115  can connect or connect to the enteral feeding tube  165  by any means understood and utilized in the art, such as by a threaded or snap connection, or by simple male-to-female insertion, among others, as will be readily understood by one having ordinary skill in the art. 
     In some embodiments, for example, the frustoconical portion  155  and elongate tube portion  150  of the gavage milk delivery component  115  can be formed of molded plastic having varying diameters for each portion formed in a stepwise sequence, as illustrated. In other embodiments, the frustoconical portion  155  and elongate tube portion  150  of the gavage milk delivery component  115  can be formed such that the transition between each segment is gradual or continuous. In other embodiments, the frustoconical portion  155  and elongate tube portion  150  can be formed as a single, continuous component, formed of the same molded plastic, rubber, silicone, or other appropriate material, as will be readily understood by one of ordinary skill in the art. 
     In some other embodiments, for example, the frustoconical portion  155  and elongate tube portion  150  of the milk delivery component  115  can be formed of plastic or some other suitable solid or semi-solid material to facilitate flow of milk or formula from the infant feeding bottle  105  to the enteral feeding tube  165 , and to allow for secure coupling between the elongate tube portion  150  and the enteral feeding tube  165 . In some embodiments, the milk delivery component  115  and/or the infant gavage feeding device  150  may be formed of bisphenol-a (BPA)-free plastic. Appropriate materials for formation of the milk delivery component  115  and the infant gavage feeding device  150  will be readily understood by one of ordinary skill in the art. 
     Returning to  FIG. 1 , the infant gavage feeding apparatus  100  can include a retaining ring  160  to secure a base of the frustoconical portion  155  of the gavage milk delivery component  115  to the top portion  170  of the infant feeding bottle  105 . In some embodiments, for example, the retaining ring  160  can include a threaded component on an inner surface thereof for connecting the retaining ring  160  to the infant feeding bottle  105  in order to form a liquid-tight seal. In some other embodiments, various other attachment means between the retaining ring  160  and the top portion  170  of the infant feeding bottle  105  can be utilized, such as a snap fitting or the like, as will be readily understood by one of ordinary skill in the art. 
     As further illustrated in  FIG. 2 , the infant gavage feeding apparatus  100  can additionally include a cord component  125  to releasably connect the gavage milk delivery component  115  to the infant feeding bottle  105  in order to transition the infant feeding bottle  105  from nipple feeding to gavage feeding. 
     According to an embodiment of the present disclosure, the nipple  120  of the infant feeding bottle  105  may be removed from the top portion  170  of the infant feeding bottle  105  in order to allow attachment of the retaining ring  160  to the infant feeding bottle  105 , as illustrated in  FIG. 2  for example. 
     In some embodiments, for example, the cord component  125  may be positioned to releasably connect the gavage milk delivery component  115  to the infant feeding bottle  105  when the gavage milk delivery component  115  is not in use. In addition, the cord component  125  may be detachable from the gavage milk delivery component  115  when the retaining ring  160  is secured to the top portion  170  of the infant feeding bottle  105 . In some embodiments, the cord component  125  may be made of plastic or like materials. In some embodiments, the cord component  125  may be designed to be reusable and for multiple uses. In various embodiments, the cord component  125  may include a breaking point positioned thereon at an appropriate location. The breaking point can allow the cord component  125  to disconnect into two separate components when sufficient force is applied on the cord component  125  to allow the cord component  125  to be detached from the gavage milk delivery component  115 . The separated portions of the cord component  125  may be connected at the breaking point by any means understood and utilized in the art, such as by a magnetic, snap on, or male-to-female insertion, among others, as will be readily understood by one having ordinary skill in the art. In other embodiments, the breaking point can include a thinner portion of the material from which the cord component  125  is formed, such that the strength of the breaking point is weaker than that of the remainder of the cord component  125 . As pressure is applied to the cord component  125 , the weaker breaking point can detach. 
     In the embodiment illustrated in  FIG. 4 , for example, the cord component  125  may include a clip  130  positioned thereon to secure the infant gavage feeding apparatus  100  in an inverted orientation, for example to a caregiver, to an intravenous pole, to a piece of furniture, or the like, in order to allow hands-free feeding when the cord component  125  has been detached from the gavage milk delivery component  115 . 
     As further illustrated in  FIG. 4 , the cord component  125  can further include a grip component  135  positioned at a proximal end of the cord component  125  in order to removably attach the cord component  125  to the infant feeding bottle  105 . In an embodiment, the grip component  135  of the cord component can  125  be positioned to slidably move along a longitudinal axis of the infant feeding bottle  105  after the cord component  125  is detached from the gavage milk delivery component  115  in order to allow the infant gavage apparatus  100  to be stably supported when the infant gavage apparatus  100  is in an inverted orientation, as illustrated in  FIG. 5 . The grip component  135  can include one or more ring structures to partially or fully encircle and removably secure the gavage milk delivery component  115  to the infant feeding bottle  105 . In other embodiments, various other removable grip component means are contemplated, as will be readily understood by one of ordinary skill in the art. 
     In some embodiments, for example as illustrated in  FIG. 2 , the infant gavage feeding apparatus  100  can further include a releasable seal  140  positioned at a bottom of the retaining ring  160 . In an embodiment, a perimeter of the releasable seal  140  is attached to a perimeter of the bottom of the retaining ring  160  thereby sealing the bottom of the retaining ring  160  in order to prevent contamination of an interior of the gavage milk delivery component  115  when the gavage milk delivery component  115  is not in use. The releasable seal  140  can be made from polymer materials such as polystyrene or polyethylene, among others, or can be a plastic or foil cover, as will be readily understood by one having ordinary skill in the art. The resealable seal  140  can be positioned to create a durable seal for repeat use in some examples, or can be disposable after a single use in other examples, and can be ergonomically easy to lift and peel away from the bottom of the retaining ring  160 . 
     As illustrated in  FIG. 4 , the infant gavage feeding apparatus  100  can further include a removable protective cap  145  positioned to cover the gavage milk delivery component  115  when the protective cap  145  is affixed to the retaining ring  160 , in order to prevent contamination of the elongate tube portion  150  of the gavage milk delivery component  115  when the gavage milk delivery component  115  is not in use. By way of example, the removable protective cap  145  can include a hemispherical dome cap or a cylindrical cap, among others, as will be readily understood by one having ordinary skill in the art. The removable protective cap  145  can be formed of opaque, translucent, or transparent medical-grade material. The removable protective cap  145  can connect to the retaining ring  160  by means of a snap-fitting connection, by a threaded connection, or by any other means as will be readily understood by one of ordinary skill in the art. 
     In some embodiments, the gavage milk delivery component  115  can further include a shoulder portion connected to and positioned between the base of the frustoconical portion  155  and the retaining ring  160 . The shoulder portion can be positioned and angled so as to allow a flow of milk from the infant feeding bottle  105  into the enteral feeding tube  165  via the gavage milk delivery component  115 . The angle at which the shoulder portion transitions between the base of the frustoconical portion  155  and the retaining ring  160  can help to prevent backup of the flow of milk from the infant feeding bottle  105  into the enteral feeding tube  165 , as will be readily understood by one of ordinary skill in the art. 
     The present disclosure is also directed to an infant milk dual-delivery device  200  to transform an infant feeding bottle  105  to an alternate nipple feeding and gavage feeding apparatus. In some embodiments, the infant milk dual-delivery device  200  can be disposable after a single use. In other embodiments, infant the milk dual-delivery device  200  can be cleaned and sterilized between uses for reuse. The device  200 , for example, can be fabricated from a variety of materials, including, but not limited to, common non-toxic and resilient polymeric materials, such as polyethylene or polyterephthalate, which are the preferred materials for infant feeding. In addition, the device  200  may be formed of medical-grade, lightweight, and highly durable thermal shock-resistant borosilicate glass, among others, as will be readily understood by one having ordinary skill in the art. The device  200  can also include other sturdy materials that are potentially easy to clean and sterilize. 
     In one or more embodiments, for example as illustrated in  FIGS. 6 and 7 , the device can include a nipple receiving component  220 , a gavage milk delivery component  215 , and a retaining ring  260 . In some embodiments, the nipple receiving component  220  can be positioned to allow the nipple  110  to be removably connected to the infant milk dual-delivery device  200  in order to facilitate nipple feeding. In various embodiments, the nipple receiving component  220  can include a threaded component along an outer perimeter thereof for connecting the nipple  110  to the nipple receiving component  220  in order to form a liquid-tight seal. In other embodiments, various other attachment means between the nipple  110  and the nipple receiving component  220  may be utilized, such as a snap fitting or the like, as will be readily understood by one of ordinary skill in the art. 
     According to an embodiment of the present disclosure, the gavage milk delivery component  215  can include a frustoconical portion  155  and an elongate tube portion  150  connected to and extending outwardly and distally from the frustoconical portion  155 . The elongate tube portion  150  can be positioned to connect with an enteral feeding tube  165  when positioned adjacent thereto in order to facilitate gavage feeding. 
     As illustrated in  FIG. 7 , the retaining ring  260  can be positioned to secure a base of the gavage milk delivery component  215  to a top portion  170  of an infant feeding bottle  105 . The nipple  120  of the infant feeding bottle  105  is removable from the top portion  170  of the infant feeding bottle  105  in order to allow attachment of the retaining ring  260  to the infant feeding bottle  105 . 
     In various embodiments, the base of the gavage milk delivery component  215  can be secured to the top portion  170  of the infant feeding bottle  105  via various attachment means such as a snap fitting. In another embodiment, the retaining ring  261  can include a threaded component encircling an outer portion thereof for connecting the retaining ring  261  to the top portion  170  of the infant feeding bottle  105 . In other embodiments, various other attachment means between the retaining ring  260  and the top portion  170  of the infant feeding bottle  105  may be utilized, such as a snap fitting or the like, as will be readily understood by one of ordinary skill in the art. 
     The nipple receiving component  220  may be substantially cylindrical and tubular in shape to fit into the bottom of an existing and commercially available nipple receiving portion  120 . In this way, a standard infant feeding bottle  105  and a standard nipple  110  can be utilized with the infant milk dual-delivery device  200  so as to convert a standard nipple-feeding bottle to a dual-delivery bottle capable of alternate nipple and gavage feedings, without requiring removal of the nipple when transitioning to gavage feeding. This configuration allows for seamless transitions between nipple and gavage feeding, so as to limit any interruption or unsettling of the baby&#39;s feeding process. 
     In the embodiments as illustrated in  FIGS. 6 and 7 , for example, the gavage milk delivery component  215  and the nipple receiving component  220  may be positioned in a branched configuration. The infant milk dual-delivery device  200  can be positioned in a first position, in which the nipple  110  is pointed downward and the gavage milk delivery component  215  is positioned upward, so as to enable nipple feeding via the nipple  110 . In the first position, milk in the infant feeding bottle  105  will be allowed to flow by gravity into the nipple  110 , without entering the elevated gavage milk delivery component  215 . The infant milk dual-delivery device  200  may also be rotated to be positioned in a second position, in which the gavage milk delivery component  215  is positioned to point downward while the nipple  110  is pointed upward, so as to enable gavage feeding via the gavage milk delivery component  215 . In the second position, milk in the infant feeding bottle  105  will be allowed to flow by gravity into the gavage milk delivery component  215 , without entering the elevated nipple  110 . In this way, a seamless transition between nipple and gavage feeding can be achieved. 
     In another embodiment, the infant milk dual-delivery device  205  can also include a flow closure component  225  and a controller  230 . The flow closure component  225  can be positioned in order to divide a milk flow path from the infant feeding bottle  105  into a first channel and a second channel. The first channel can include the milk flow path from the infant feeding bottle  105  to the  110  nipple, and the second channel may include the milk flow path from the infant feeding bottle  105  to the gavage milk delivery component  215 . The first channel may facilitate nipple feeding and the second channel may facilitate gavage feeding. In some embodiments, the flow closure component  225 , for example, can be a cap, flap, tab, or the like, made of an impermeable material and appropriate dimension to complement the dimension of the interstitial space formed between the outer surfaces of the nipple receiving component  220  and the gavage milk delivery component  215  of the infant milk dual-delivery device  200 , or any other suitable component positioned to block the first channel and prevent liquid, such as milk, from flowing into the first channel to facilitate nipple feeding. 
     In some embodiments, the controller  230  can be positioned to transition the flow closure component  225  between a first position to facilitate nipple feeding via the first channel and a second position to facilitate gavage feeding via the second channel. In some embodiments, the controller can include any controlling means to transition the flow closure component between a first position and a second position, such as a knob, a button, a handle, or a crown, among others, as will be readily understood by one having ordinary skill in the art. The controller  230  can be ergonomically designed and varied in size, shape, and materials. The controller  230 , for example, can also be externally threaded or grooved for ease of grip while operating the controller, as will be readily understood by one having ordinary skill in the art. The controller  230  can be actuated by exerting sufficient force, such as by a rotation, sliding, or the like, to cause the flow closure component  225  to open the first channel and allow milk to flow from the infant feeding bottle  105  into the nipple  110 . Similarly, the controller  230  can be actuated by exerting sufficient force, such as by a rotation, sliding, or the like, to cause the flow closure component  225  to open the second channel and allow milk to flow from the infant feeding bottle  105  into the gavage milk delivery component  215 . 
     In another embodiment of the infant milk dual-delivery device  300  as illustrated in  FIG. 8 , the gavage milk delivery component  315  and the nipple receiving component  320  can be positioned in series, in a stacked configuration in order to allow milk to flow through the gavage milk delivery component  315  and the nipple  110  when nipple feeding. Similarly, the stacked configuration can allow milk to flow through the gavage milk delivery component  315  when the nipple  110  is removed from the nipple receiving component  320  in order to facilitate gavage feeding. According to an embodiment, the gavage milk delivery component  315  and the nipple receiving component  320 , for example, can be formed as a single and lightweight structure in that they are inseparable portions of an integrally formed structure, as will be readily understood by one of ordinary skill in the art. 
     In some embodiments, the upper portion of the nipple receiving component  320  may include a threaded component positioned on an outer surface thereof for receiving and connecting the nipple  120  to the nipple receiving component  320  in order to form a liquid-tight seal. In various embodiments, the nipple  120  can be connected to the nipple receiving component  320  by any means understood and utilized in the art, such as by a threaded or snap connection. 
     As illustrated in  FIG. 9 , for example, the infant milk dual-delivery device  300  can further include a funnel  365 . The apex  345  of the funnel  365  can include an elongated portion that is complementary to and insertable into a distal end of the elongate tube portion  150  of the gavage milk delivery component  315 . In an embodiment, the base  350  of the funnel  365  can be positioned to circumvent a base of the nipple  110  when positioned thereon in order to allow milk in the nipple  110  to flow back into the infant feeding bottle  105  through the elongate tube portion  150  of the gavage milk delivery component  315  when the infant feeding bottle  105  is positioned in an upright position in order to avoid loss of milk. For example, milk may flow through the gavage milk delivery component  315  into the nipple  110  when the infant feeding bottle  110  is in an inverted position. When the infant feeding bottle  110  is rotated to an upright position, any milk remaining in the nipple  110  that has not been drained from the nipple by the baby will flow back downward toward the gavage milk delivery component  315 . In the absence of the funnel  365 , the milk may be trapped around the interstitial space formed between the elongate tube portion of the gavage milk delivery component  315  and the nipple receiving component  320 . With the presence of the funnel  365 , however, the milk may be directed to flow back through the gavage milk delivery component  315  and into the infant feeding bottle  105 . In this way, loss of milk can be avoided. The funnel  365 , for example, can be formed of medical-grade and non-toxic sheet or film plastic, such as polyethylene or the like, as will be readily understood by one having ordinary skill in the art. 
     In some embodiments, the enteral feeding tube  165  can be inserted into a distal end of the elongate tube portion  150  of the gavage milk delivery component  315  when the funnel  365  is removed from the gavage milk delivery component  315  in order to facilitate gavage feeding, as illustrated in  FIG. 9 , for example. 
     As illustrated in  FIG. 12 , the infant milk dual-delivery device  300  can further include a flow closure component  330  positioned to divide a milk flow path from the infant feeding bottle  105  into a first channel and a second channel. The first channel can include the milk flow path from the infant feeding bottle  105  through an area circumventing an opening  340  in the base of the gavage milk delivery component  315  and into the nipple  110 . The second channel can include the milk flow path from the infant feeding bottle  105  through the opening  310  in the base of the gavage milk delivery component  315 . The gavage milk delivery component  315  can be attached to the retaining ring  360  by a plurality of supporting components  335  positioned around an outer perimeter of the gavage milk delivery component  315  in order to secure the gavage milk delivery component  315  to the retaining ring  360 , while still allowing milk to flow along the first channel in the through an area circumventing an opening  340  in the base of the gavage milk delivery component  315  and into the nipple  110 . 
     In some embodiments, the flow closure component  330  can include a plurality of moveable overlapping covers that fit together in a circular arrangement. As illustrated in  FIG. 13 , milk flows from the infant feeding bottle  105  through the gavage milk delivery component  315  when the flow closure component covers an area  340  circumventing an opening  310  in the base of the gavage milk delivery component  315  and exposes the opening  310  in the base of the gavage milk delivery component  315 . 
     In another embodiment, milk flows from the infant feeding bottle  105  through an area  340  circumventing an opening  310  in the base of the gavage milk delivery component  315  and into the nipple  110  when the flow closure component covers the opening  310  in the base of the gavage milk delivery component  315  and exposes the area  340  circumventing an opening  310  in the base of the gavage milk delivery component  315 . In other embodiments, various other means of alternately covering the base of the gavage milk delivery component  315  and exposing the area  340  circumventing the opening  310  in the base of the gavage milk delivery component  315 , and uncovering the base of the gavage milk delivery component  315  while covering the area  340  circumventing the opening  310  in the base of the gavage milk delivery component  315  may be used, such as rotating or sliding covers, flaps, or closures, as will be readily understood by one of ordinary skill in the art. 
     In the embodiments illustrated in  FIGS. 12 and 13 , the infant milk dual-delivery device  300  can further include a removable protective cap  370  positioned to cover the gavage milk delivery component  315  when the flow closure component  330  is positioned in order to divert milk along the first channel. The removable protective cap  370  can also be positioned to prevent contamination of the elongate tube portion  150  of the gavage milk delivery component  315  when the gavage milk delivery component  315  is not in use. 
     Additionally, the removable protective cap  370 , for example, can be connected to the flow closure component  330  in order to cause the movement of the plurality of moveable overlapping covers and thereby control the diversion of milk flow between the first and second channel. For example, rotating the removable protective cap  370  may cause the flow closure component  330  to rotate, causing the individual flaps or components of the flow closure component  330  to either dilate or fan out, or constrict or fold inward, depending on the directionality of the rotation. In other embodiments, other methods of transitioning the flow closure component  330  are contemplated, as will be readily understood by one of ordinary skill in the art. 
     The present disclosure is also directed to a method to operate an infant gavage feeding apparatus  100 . In some embodiments, for example, the method can include attaching a gavage milk delivery component  115  to an infant feeding bottle  105  as illustrated in  FIG. 1 . The cord component  125  is positioned to releasably connect the gavage milk delivery component  115  to the infant feeding bottle  105  when the gavage milk delivery component  115  is not in use. 
     In some embodiments as illustrated in  FIG. 4 , the gavage milk delivery component  115  can include a frustoconical portion  155  and an elongate tube portion  150  connected to and extending outwardly and distally from the frustoconical portion  155 . The elongate tube portion  150  can be positioned to connect with an enteral feeding tube  165  when positioned adjacent thereto in order to facilitate gavage feeding. 
     As illustrated in  FIG. 2 , the method to operate an infant gavage feeding apparatus  100  can also include removing a nipple  120  from a top portion  170  of the infant feeding bottle  105 . The nipple  120  can be a standard baby nipple of any appropriate size, shape, or material as required for the needed purpose. As further illustrated in  FIG. 2 , the nipple  120  can be secured to the top portion  170  of the infant feeding bottle  105  via various attachment means such as snap fitting or screw fitting. In some embodiments, removing the nipple portion  120  can include, for example, rotating the nipple portion  120  on a threaded portion of the top portion  170  of the infant feeding bottle  105 . In other embodiments, the nipple portion  120  can be removed from the infant feeding bottle  105  by any other acceptable means, such as by unsnapping or the like, as will be readily understood by one of ordinary skill in the art. 
     According to an embodiment of the present disclosure and illustrated in  FIG. 2 , the nipple  120  is removable from the top portion  170  of the infant feeding bottle  105  in order to allow attachment of a retaining ring  160  to the infant feeding bottle  105 . In an embodiment, for example, the retaining ring  160  can be positioned to secure a base of the frustoconical portion  155  of the gavage milk delivery component  115  to the top portion  170  of the infant feeding bottle  105 . 
     In some embodiments, for example, the method can further include replacing the removed nipple  120  with the gavage milk delivery component  115  as illustrated in  FIG. 3 . The gavage milk delivery component  115  can be secured to the top portion  170  of the infant feeding bottle  105  by a screw, snap, or other suitable connection, as will be readily understood by one of ordinary skill in the art. 
     As further illustrated in  FIG. 3 , the attachment of the retaining ring  160  to the infant feeding bottle  105  may be positioned such that tightening the retaining ring  160  to the top portion  170  of the infant feeding bottle  105  breaks the cord component  125  in order to disconnect the gavage milk delivery component  115  from the grip component  135 . As the retaining ring  160  is rotated on the top portion  170  of the infant feeding bottle  105 , the cord component  125  may be stretched and extended such that the weakest point of the cord component  125  is caused to break, thereby separating the gavage milk delivery component  115  from the infant feeding bottle  105 . 
     As illustrated in  FIG. 4 , the method can also include fluidly connecting a distal end of the elongate tube portion  150  of the gavage milk delivery component  115  to a proximal end of the enteral feeding tube  165  and inverting the infant feeding bottle  105  to initiate a flow of milk from the infant feeding bottle  105  into the enteral feeding tube  165  via the gavage milk delivery component  115  in order to facilitate gavage feeding. 
     In some embodiments, for example, the method can further include attaching a retaining ring  160  to the infant feeding bottle  105 , the retaining ring  160  securing a base of the frustoconical portion  155  of the gavage milk delivery component  115  to the top portion  170  of the infant feeding bottle  105 . As illustrated in  FIG. 2 , prior to replacing the removed nipple  112  with the gavage milk delivery component  115 , the method can further include removing a releasable seal  140  from a bottom of the retaining ring  160  to expose the base of the frustoconical portion  155  of the gavage milk delivery component  115  in order to allow the gavage milk delivery component  115  to be fluidly connected to the infant feeding bottle  105 . The releasable seal  140  can be positioned at the bottom of the retaining ring  160  and a perimeter of the releasable seal  140  can be attached to a perimeter of the bottom of the retaining ring  160  thereby sealing the bottom of the retaining ring  160  in order to prevent contamination of an interior of the gavage milk delivery component  115 . 
     In some embodiments as illustrated in  FIG. 3 , prior to replacing the removed nipple  112  with the gavage milk delivery component  115 , the method can also include removing a removable protective cap  145  from the retaining ring  160  to expose the elongate tube portion  150  of the gavage milk delivery component  115  in order to allow coupling of the elongate tube portion  150  of the gavage milk delivery component  115  to the enteral feeding tube  165  when the removable protective cap  145  is removed. The removable protective cap  145  can be positioned to cover the gavage milk delivery component  115  when the removable protective cap  145  is affixed to the retaining ring  160  in order to prevent contamination of the elongate tube portion  150 . 
     In some embodiments, for example, the method can also include attaching a grip component  135  to the infant feeding bottle  105 . A proximal end of the cord component can secure the gavage milk delivery component  115  to the infant feeding bottle  105 . The grip component  135  may be positioned at a distal end of the cord component  125 , so as to connect the gavage milk delivery component  115  to the infant feeding bottle  105 . The grip component  135  can include a stiff or flexible component that partially or wholly encircles the outer diameter of the infant feeding bottle  105 . Additionally, the method can include attaching the retaining ring  160  to the infant feeding bottle  105 , thereby breaking the cord component  125  when the retaining ring  160  is attached to the infant feeding bottle  105  in order to disconnect the gavage milk delivery component  115  from the grip component  135 . The method can further include sliding the grip component  135  of the cord component  125  downwardly along a longitudinal axis of the infant feeding bottle  105  after the cord component  125  is detached from the gavage milk delivery component  115  in order to allow the infant gavage feeding apparatus  100  to be stably supported when the infant gavage feeding apparatus  100  is in an inverted position, as illustrated in  FIG. 4 . 
     As illustrated in  FIG. 5 , the method can further include attaching a clip  130  positioned on the cord component to a user  560  to secure the infant gavage feeding apparatus  100  in an inverted orientation in order to allow hands-free feeding.

     The present disclosure is also directed to a method to operate an alternate nipple feeding and gavage feeding apparatus in which a gavage milk delivery component and a nipple receiving component are arranged in a branched configuration. 
     In some embodiments, for example, the method can include removing a nipple  120  from a top portion  170  of the infant feeding bottle  105 . The nipple  120  is removable from the top portion  170  of the infant feeding bottle  105  in order to allow attachment of an infant milk dual-delivery device  200  to the top portion  170  of the infant feeding bottle  105 . The method can also include attaching the infant milk dual-delivery device  200  to the top portion  170  of the infant feeding bottle  105 . 
     The infant milk dual-delivery device  200  can include a gavage milk delivery component  215 . The gavage milk delivery component  215  can include a frustoconical portion  155  and an elongate tube portion  150  connected to and extending outwardly and distally from the frustoconical portion  155 . The elongate tube portion  150 , for example, can be positioned to connect with an enteral feeding tube  165  when positioned adjacent thereto in order to facilitate gavage feeding. The infant milk dual-delivery device  200  can also include a retaining ring  260  to secure a base of the gavage milk delivery component  215  to the top portion  170  of the infant feeding bottle  105 . The infant milk dual-delivery device  200  can further include a nipple receiving component positioned to allow the nipple  110  to be removably connected to the infant milk dual-delivery device  200  in order to facilitate nipple feeding. In some embodiments, the gavage milk delivery component  215  and the nipple receiving component  220  can be positioned in a branched configuration in order to alternately facilitate nipple feeding and gavage feeding. 
     The method can also include connecting the nipple  112  to the nipple receiving component  220  in order to facilitate nipple feeding and inverting the infant feeding bottle  105  to initiate a flow of milk from the infant feeding bottle  105  alternately into the nipple  112  in order to facilitate nipple feeding and into the gavage milk delivery component  215  in order to facilitate gavage feeding. For example, the infant feeding bottle  105  may be inverted and positioned such that the nipple  112  is positioned downward, while the gavage milk delivery component  215  is positioned upward, such that milk is allowed to flow by gravity from the infant feeding bottle  105  into the nipple  112 , without escaping through the gavage milk delivery component  215 . Alternately, the infant feeding bottle  105  may be inverted and positioned such that the gavage milk delivery component  215  is positioned downward, while the nipple  112  is positioned upward, such that milk is allowed to flow by gravity form the infant feeding bottle  105  into the gavage milk delivery component  215 , without escaping through the nipple  112 . 
     In some embodiments, for example, the method can further include positioning a flow closure component  225  in a first position in order to facilitate nipple feeding. The flow closure component  225  can be positioned in order to divide a milk flow path from the infant feeding bottle  105  into a first channel and a second channel.

The second position may open the second channel forming the milk flow path from the infant feeding bottle  105  to the gavage milk delivery component  215 . A controller  230  may be positioned to transition the flow closure component  225  between the first position and the second position. Such transition can include any of rotation, sliding, switching, or the like, as will be readily understood by one of ordinary skill in the art. 
     The present disclosure is also directed to a method to operate an alternate nipple feeding and gavage feeding apparatus whereby a gavage milk delivery component and a nipple receiving component are arranged in series, in a stacked configuration. 
     In one or more embodiments, the method an include removing a nipple  112  from a top portion  170  of the infant feeding bottle  105 . The nipple  120  is removable from the top portion  170  of the infant feeding bottle  105  in order to allow attachment of an infant milk dual-delivery device  300  to the infant feeding bottle  105 . The method can further include attaching the infant milk dual-delivery device  300  to the top portion  170  of the infant feeding bottle  105 . 
     According to an embodiment of the present disclosure, the infant milk dual-delivery device  300  can include a gavage milk delivery component  315 . The gavage milk delivery component  315  can include a frustoconical portion  155  and an elongate tube portion  150  connected to and extending outwardly and distally from the frustoconical portion  155 . The elongate tube portion  150  can be positioned to connect with an enteral feeding tube  165  when positioned adjacent thereto in order to facilitate gavage feeding. In some embodiments, for example, the infant milk dual-delivery device  300  can include a retaining ring  360  to secure a base  325  of the gavage milk delivery component  315  to the top portion  170  of the infant feeding bottle. The infant milk dual-delivery device  300  can further include a nipple receiving component  320  positioned to allow the nipple  110  to be removably connected to the infant milk dual-delivery device  300  in order to facilitate nipple feeding. In an embodiment, the gavage milk delivery component  315  and the nipple receiving component  320  can be positioned in a stacked configuration in order to alternately facilitate nipple feeding and gavage feeding. 
     In some embodiments, for example, the method can further include inserting the apex of a funnel  345  into a distal end of the elongate tube portion  150  of the gavage milk delivery component  315 . As illustrated in  FIG. 8 , for example, the base  350  of the funnel  365  can be positioned to circumvent a base of the nipple  110  when positioned thereon in order to allow milk in the nipple  110  to flow back into the infant feeding bottle  105  through the elongate tube portion  150  of the gavage milk delivery component  315  when the infant feeding bottle  105  is positioned in an upright position in order to avoid loss of milk. As illustrated in  FIG. 10 , the method can also include connecting the nipple  110  to the nipple receiving component  320  in order to facilitate nipple feeding. The method can further include inverting the infant feeding bottle  105  to initiate a flow of milk from the infant feeding bottle  105  into the nipple  110  in order to facilitate nipple feeding. 
     In the embodiment illustrated in  FIG. 9 , for example, the method can further include disconnecting the nipple  110  from the nipple receiving component  320 . As further illustrated in  FIG. 9 , the method an also include removing the funnel  365  from the gavage milk delivery component  315  and fluidly connecting the distal end of the elongate tube portion  150  of the gavage milk delivery component  315  to a proximal end of the enteral feeding tube  165 . The method can additionally include inverting the infant feeding bottle  105  to initiate a flow of milk from the infant feeding bottle  105  into the enteral feeding tube  165  in order to facilitate gavage feeding, for example as illustrated in  FIG. 5 . 
     In some embodiments, the method can further include connecting the nipple  110  to the nipple receiving component  320  in order to facilitate nipple feeding, as illustrated in  FIG. 12 . The method can also include positioning a flow closure component  330  in a first position to open a first channel in order to allow the milk to flow from the infant feeding bottle  105  through an area circumventing an opening  340  in the base  325  of the gavage milk delivery component  315  and into the nipple  110 . In addition, the method can include inverting the infant feeding bottle  105  to initiate the flow of milk from the infant feeding bottle  105  into the nipple  110  in order to facilitate nipple feeding. As illustrated in  FIG. 14 , for example, the method can additionally include disconnecting the nipple  110  from the nipple receiving component  320  and fluidly connecting a distal end of the elongate tube portion  150  of the gavage milk delivery component  315  to a proximal end of the enteral feeding tube  165 . In some embodiments, the method can also include positioning the flow closure component  330  in the second position to open the second channel in order to allow milk to flow from the infant feeding bottle  105  through the opening  310  in the base  325  of the gavage milk delivery component  315 , as illustrated in  FIG. 13 .
