These teachings relate generally to enteral feeding practices.
Enteral feeding practices are known in the art. Enteral feeding refers to introducing food (and/or beverages) directly into the digestive system (i.e., the stomach or small intestine) of the consumer. Such content is typically placed in the digestive system via a feeding tube. The feeding tube itself may be introduced into the digestive system via the consumer's throat or through an opening in their abdomen.
By one approach the feeding tube connects to an open-top funnel or the like. An attendant then pours the food/beverage into that open-top mechanism and gravity directs the food/beverage through the feeding tube and directly into the consumer's digestive system. By another approach a relatively large bag, bottle, or other container (containing, for example, about 1,000 milliliters) of the desired food/beverage is hung on an IV pole and a tube provides the contents of that bag to an electric pump that then delivers a metered flow of the food/beverage directly into the consumer's digestive system via a delivery tube. Alternately, the tube could provide the product by means of gravity flow in the absence of a pump.
The foregoing approaches are generally suitable for the stated function of delivering digestible materials directly to a consumer's digestive tract. That said, however, existing approaches do not suit all needs and wishes of all users and all application settings. As one general example in these regards, existing approaches have a very institutional look-and-feel regardless of whether these materials are employed in a hospital, home, school setting, and so forth. Prior art approaches also tend to emphasize, at every turn and opportunity, that the person receiving this food is partaking of a “meal” via anything other than an ordinary dining experience.
The foregoing approaches may also be very inconvenient to the user, especially in a mobile or ambulatory setting. Such approaches also typically require a portable electric pump and/or tubing mechanisms that are inconvenient to carry and which can further serve to draw unwanted and undo attention to the user's condition.
The above needs are at least partially met through provision of the method and apparatus for a squeezable food container having a direct feeding tube connector described in the following detailed description, particularly when studied in conjunction with the drawings, wherein:
Elements in the figures are illustrated for simplicity and clarity and have not necessarily been drawn to scale. For example, the dimensions and/or relative positioning of some of the elements in the figures may be exaggerated relative to other elements to help to improve understanding of various embodiments of the present teachings. Also, common but well-understood elements that are useful or necessary in a commercially feasible embodiment are often not depicted in order to facilitate a less obstructed view of these various embodiments of the present teachings. Certain actions and/or steps may be described or depicted in a particular order of occurrence while those skilled in the art will understand that such specificity with respect to sequence is not actually required. The terms and expressions used herein have the ordinary technical meaning as is accorded to such terms and expressions by persons skilled in the technical field as set forth above except where different specific meanings have otherwise been set forth herein.
Generally speaking, pursuant to these various embodiments, a sealed and squeezable container of pre-filled squeezable food that is sized no larger than a single meal serves as a prepackaged, one-time-use, meal-appropriate enteral food dispenser. By one approach the squeezable container has a dispensing port comprising a direct feeding tube connector.
So configured, the pre-filled container contains a considerably smaller amount of food than typical prior art pre-filled containers. This sizing, however, well serves the purpose of providing single-meal servings and hence better accommodating at least some of the actions, behaviors, and accoutrements of partaking of an ordinary dining experience rather than merely being impersonally-infused with biological fuel. By one approach, if desired, the pre-filled container contains less than a full-sized single meal. For example, the container may be sized no larger than about one half of a single meal.
As noted above, this enteral food dispenser is squeezable and the food contained therein is squeezable as well. So configured the consumer (or their guardian, aide, or the like) squeezes the container to remove the food from the container and thereby introduce the food via a feeding tube into the consumer's digestive tract. This approach, too, differs greatly from typical prior art practice but again offers an approach that can better accord with more ordinary eating practices than those prior art behaviors. In many cases, then, it can be acceptable or even useful for the squeezable container to lack a hanging interface as the delivery approach eschews the need to hang the container from, for example, an IV pole.
The aforementioned direct feeding tube connector can assume any of a variety of form factors. Examples in these regards include but are not limited to threaded interfaces, friction-fit interfaces, snap-fit interfaces, and so forth (though needles and the like are excluded). By one approach the direct feeding tube connector observes the technical requirements of an available standard (legal or voluntarily-observed) that specifies the size, shape, and connection for feeding tube connectors to the exclusion of connectors for other kinds of tubes to thereby help assure that the direct feeding tube connector compatibly connects to nothing but a feeding tube.
By one approach a flow limiter serves to limit a flow rate of the squeezable food from the squeezable container through the direct feeding tube connector. Such a flow limiter can also serve, for example, to prevent the food from spilling from or otherwise exiting the container when inadvertently tipped or the like.
By another approach, in lieu of the foregoing or in combination therewith, a one-way valve can be disposed to prevent material (such as gas or other contents of the consumer's digestive system) from entering the squeezable container via the direct feeding tube connector. Such a one-way value may also serve in part as the aforementioned flow limiter to thereby also prevent the food from spilling from or otherwise exiting the container when inadvertently tipped or the like by requiring a degree of pressure within the container to open the valve in the desired direction of flow.
Such a squeezable container can better serve an application setting that more closely accords with the behaviors, preparations, and appearances of an ordinary meal. By one approach the exterior surface of the container can include graphic content that furthers this impression/experience. That graphic content can comprise, for example, one or more illustrations of recognizable food items that comprise the squeezable food (such as raw or prepared vegetables, fruits, grain and meat products, dairy products, and so forth) and/or textual description of such food items. Such information can better inform the selection of particular containers/foods for a given meal in contravention of more ordinary practices in these regards. This kind of visual cue can also help many consumers better achieve a sense of consuming a more traditional meal than typical prior art practices.
These and other benefits may become clearer upon making a thorough review and study of the following detailed description. Referring now to the drawings, and in particular to
At block 101 this process 100 provides a container 201 (see
This container 201 is comprised of a readily-deformable material. So configured the container 201 can be readily squeezed (when filled) by the average human adult or minor (at least over the age of, say, three years old) to thereby cause the contents of the container 201 to be displaced therefrom in an orderly manner. A variety of materials will serve in these regards including various plastic films and metallic foils. These teachings will also readily accommodate any of a variety of laminates as well.
Generally speaking the interior surfaces of the container 201 should be well suited to the purpose of longer-term safe contact with food without tainting such food with any materials-based taste or scent. Such materials and their corresponding manner of use in these regards comprises a well-understood area of endeavor and accordingly no further description will be provided here for the sake of brevity.
For many purposes it will suffice for the container 201 to have a bag-like form factor. In particular, the periphery of the container 201 can comprise a hermetically-sealed periphery save for an opening 202 through which food can be introduced into the interior 203 of the container 201. Such a seal can be created in any of a variety of ways including but not limited to the use of adhesives, applied heat, sonic welding, and so forth. These teachings will accommodate other form factors, such as a syringe-like form factor, if desired.
By one approach the exterior of the container 201 can include graphic content 204 (schematically represented here by a star presented in phantom lines). This graphic content can include, for example, one or more illustrations of at least one food item contained by the container 201 and/or a textual description of such a food item. Such an illustration can vary as desired and might comprise, for example, a photographic image or an artist's rendition of an actual food item (either in a raw or prepared state or as part of a serving suggestion). Similarly, the content of the text can vary as desired. To the extent that the container 201 includes text the text can present information in as many languages as may be desired.
Referring momentarily to
By one approach this dispensing port 300 includes a flow limiter to limit a flow rate of the squeezable food from the squeezable container. Various approaches are known in the art in these regards and include but are not limited to reduced-diameter orifices, membranes, and so forth. By one approach, this flow limiter is configured to require at least some threshold level of pressure being applied to the squeezable food in order to open and permit the food to pass through the flow limiter.
By another approach, in lieu of the foregoing or in combination therewith, this dispensing port 300 can include a one-way valve disposed to prevent material from entering the squeezable container via the dispensing port 300. During use, for example, such a one-way valve can prevent a backflow of the consumer's digestive fluids and solids, gases, and so forth. Again, various known one-way valves can be so employed as desired.
In this illustrative example the dispensing port 300 includes a short tube 301 of flexible food-safe material (such as but not limited to silicon) (from perhaps 1 centimeter to about 10 centimeters in length) that terminates in a direct feeding tube connector 302. (These teachings will readily accommodate other approaches in these regards. For example, dispensing port 300 may lack the short tube 301.) Being a “direct feeding tube connector,” this connector is configured, shaped, and sized to connect securely (albeit removably and temporarily) to a feeding tube with a water-tight seal.
“Feeding tubes” are known in the art and constitute a flexible tube (often comprised of silicon) that is designed, packaged, and distributed for exclusive use in enteral feeding by having one end of the tube placed directly within the consumer's digestive tract (i.e., the stomach or the small intestine) via that person's nose or mouth (by one approach) or via an opening formed in and through the user's skin (by another approach).
Referring to
In some cases the technical specifications for such a connection may be stipulated by a legal, industrial, or de facto standard. Such a standard may specify, for example, a connector that is to be exclusively used for feeding tube connections to thereby avoid the possibility of inadvertently connecting a source of enteral feeding content to anything other than a feeding tube. The present teachings will accommodate a variety of approaches in these regards including direct feeding tube connectors employing one or more of a threaded interface, a friction-fit interface, a snap-fit interface, a hooks-and-loops interface, and/or a magnetic interface to compatibly engage the connector with a feeding tube.
Referring momentarily to
Referring again to
As used herein the word “squeezable” as applied to food will be understood to refer to food that is in a liquid or slurry form ranging from the consistency of water to non-chunky applesauce or the like. Accordingly, “squeezable food” includes liquids such as water or other beverages, liquefied food solids, and formula. As used herein, “liquefied” refers to a state where the food is sufficiently liquid to pass unimpeded through a feeding tube.
Forming squeezable food products and introducing such material in containers comprises a generally well understood area of prior art endeavor and therefore requires no further description here.
At block 103 this process 100 provides for sealing the container 203 (for example, by placing and sealing-in-place the dispensing port 300) to provide a sealed, filled container that can be distributed through at least one channel of commerce to thereby provide the sealed, filled container to a consumer of the food contained therein. As indicated earlier this seal can comprise a hermetic seal as accords with prior art food-handling techniques and methodologies.
Referring to
Per these teachings this enteral food dispenser holds no more than enough food than is appropriate to a single meal (and may contain less if desired). Squeezing the food to remove the food from the dispenser, in turn, anticipates and prompts a feeding behavior that is different than that contemplated and prompted by typical prior art practice in these regards. In particular, these teachings help to prompt a behavior that can encourage self-feeding (even by young consumers) using hand machinations that suggest or even mimic some ordinary food-consumption practices.
These teachings are highly flexible in practice and will accommodate a range of modifications. As but one example in these regards, and referring to
Those skilled in the art will recognize that a wide variety of modifications, alterations, and combinations can be made with respect to the above described embodiments without departing from the scope of the invention, and that such modifications, alterations, and combinations are to be viewed as being within the ambit of the inventive concept.
