Definitions

  • This invention relates to an infant feeding device and, in particular, to the kind for use with liquid feed, a kit for feeding an infant and a feed reservoir for use in such a kit.
  • infants do not possess either the dexterity or the strength to hold and feed from a bottle or cup. Nevertheless, at this point of development, although unable to independently hold and feed from a bottle or cup, an infant possesses a strong grip. However, the current infant feeding methods do not adequately take advantage of the pronounced grip skills infants are endowed with from birth.
  • the most common infant feeder is of the bottle type for liquid feed where there is generally a reservoir bottle for containing the liquid feed and a mouthpiece mounted on the opening of the reservoir.
  • the reservoir is usually made of a stiff plastic material and the mouthpiece is usually made of moulded silicone.
  • the feed runs under gravity from the reservoir into the teat where the infant feeds by sucking and stripping the teat with its tongue.
  • This type of mouthpiece usually has several small holes or other apertures such as slits in the moulding to allow the egress of feed into the infant's mouth.
  • the flowrate for this type of feeder is determined by the apertures in the mouthpiece and cannot be varied.
  • several teats with varying flowrates are required as the infant grows up to keep pace with their feeding requirements.
  • a teat with a smaller flowrate is required for younger infants to prevent the infant from ingesting too much feed at once and choking.
  • the same teat would not be ideally suited for older infants.
  • Another factor against the suitability of these feeders for infants of all ages is the fact that there is usually no valve mechanism to prevent the feed from flowing out of the teat when there is no suction being provided by the infant.
  • baby feeding bottles of this kind are inverted, a steady amount of fluid will leave the teat.
  • a teat with a smaller flowrate to be used initially, and replaced later on with a teat with a larger flowrate.
  • feeders are further not ideally suited for use by infants in that they are generally too big for an infant to grasp comfortably. Moreover, such feeders are not designed to take advantage of the considerable gripping skills inherent in infants nor do they further develop these skills.
  • Feeding bottles which have a rigid spout, usually made from a plastics material, with apertures in the spout for letting out feed.
  • This type of feeding device is intended for an older infant with a view to training the infant to use a cup, which has a hard rim.
  • Such products effectively comprise a tumbler, with one or more handles, provided with a lid and a rigid spout.
  • Many different types are available with different sized handles, different shaped spouts and different sized cup bodies to encourage the infant to learn to grip the cup by the handle and drink from it .
  • These devices are designed to be as leakproof as possible so that, when the infant drops or knocks the cup over whilst getting used to gripping handles, very little liquid feed is spilled.
  • an infant feeding device comprising a mouthpiece adapted to deliver liquid feed to an infant, a grip member shaped to be easily grasped by an infant and means for connecting the mouthpiece to a feed reservoir.
  • feed includes liquid food, drinks, paediatric medicines, and mixtures thereof.
  • the mouthpiece is adapted to regulate the flow of liquid feed to the infant. This may be achieved in a variety of ways. For instance, the number and/or size of feeding apertures in the mouthpiece can be varied. Furthermore, some or all of the apertures may be constructed so that they only allow fluid flow through them when the infant provides a force against the mouthpiece, perpendicular to the main axis of the mouthpiece and concurrent with the forces present when an infant is stripping or biting the mouthpiece.
  • the mouthpiece is a flexible teat, such as a silicone teat or a rigid spout, preferably made of a plastics material.
  • other types of mouthpiece may be readily envisaged.
  • the grip member may be of any shape provided it can be easily grasped by an infant. However, it is preferred that the grip member comprises at least one generally elongate element preferably having a cross- section which is sufficiently small for an infant's hand to be able to grasp it. In one preferred embodiment, the grip member comprises at least one closed loop of a size which allows it to be easily grasped by an infant. Alternatively, the grip member could comprise one or more rods or tapering rods, which are preferably curved to fit the hand of an infant better.
  • the grip member comprises one or more wings or tabs of generally planar construction. These wings or tabs may be moulded to include grooves corresponding to the shape of an infant's fingers to facilitate grasping of the wings or tabs.
  • the infant feeding device of the present invention may be formed in a single piece, preferably of a suitable plastics or silicone rubber material. However, it is preferred that the individual components are detachable from one another to facilitate cleaning of the device and replacement of the mouthpiece by another mouthpiece having different characteristics, such as different flowrate, degree of softness etc..
  • the device further includes a tubular adaptor which is capable of receiving the mouthpiece.
  • the tubular adaptor is also capable of engaging the reservoir connection means.
  • the device may be provided with a tubular connector which is capable of engaging both the tubular adaptor and the reservoir connection means .
  • the tubular adaptor may comprise a collar having a flange at one end which is perpendicular to the axis of the collar and has an aperture in the flange of a size such that a mouthpiece having a corresponding flange may be fitted in a manner so that the mouthpiece projects through the aperture in the flange of the collar and the corresponding flange of the mouthpiece abuts the reverse side of the flange of the collar thereby holding the mouthpiece in position within the collar.
  • the collar may also be screwthreaded at the unflanged end so that it can be secured to the reservoir connection means by means of a corresponding screw thread on the reservoir connection means.
  • the collar may be secured to a tubular connector by means of a corresponding screw thread and the tubular connector may be secured to the reservoir connection means, for instance, by appropriately corresponding screw threads.
  • the grip member may be attached to any part of the device. However, it is preferred that the grip member is attached to the reservoir connection means, the mouthpiece, the tubular adaptor or the tubular connector.
  • the grip member may be formed as an integral part of the reservoir connection means, the mouthpiece, the tubular adaptor or the tubular connector.
  • the means of attachment is a temporary one to facilitate cleaning.
  • the grip member may be attached to an annulus which is adapted to engage the mouthpiece, reservoir connection means, tubular adaptor or tubular connector, for instance, by fitting over a suitable projection on any of these elements.
  • the feeding device contains a liquid flow control device to prevent backflow of feed and thus prevent the ingress of air into the mouthpiece. Consequently, the liquid flow control device allows the infant to ingest less air when feeding from a feeding device according to this invention.
  • the liquid flow control device can also serve to regulate the flow of liquid feed to the mouthpiece.
  • the liquid flow control device comprises a valve. In embodiments where a rigid spout is utilised, a valve can also be incorporated in the spout itself.
  • any suitable valve may be utilised in the device of the invention provided that there is little or no leakage from the mouthpiece when in an inverted position, that is, with the tip of the mouthpiece pointing downwards.
  • the valve comprises a mushroom valve. It is further preferred that the mushroom valve is mounted in an insert which is adapted for mounting in the feeding device.
  • the periphery of the mushroom valve rises above the surface on which it rests and creates a channel through which feed can flow.
  • suction is removed and the pressure drop recedes below a predetermined level, the periphery of the mushroom valve regains its original position and closes the channel .
  • the valve comprises a slit valve.
  • the slit is in the form of a cross. It is further preferred that the slit valve is mounted in an insert which is adapted for mounting in the feeding device. It is also preferred that the slit valve is inwardly domed, that is, domed in a direction against the direction of flow of the feed when the feeding device is in use.
  • the slit opens and o allows feed to flow.
  • suction is removed and the pressure drop recedes below a predetermined level, the slit closes again preventing further feed from flowing.
  • the reservoir connection means could be attached to the valve insert.
  • the mouthpiece may be attached to the valve insert and the reservoir connection means may also be attached to the valve insert on the opposite side of the insert to the mouthpiece.
  • the means for attachment on both sides of the insert is the same.
  • the connecting means may take the form of a screw thread or a push fit arrangement .
  • the valve insert could be used in either orientation, that is, it is effectively reversible.
  • the valve utilised in this embodiment is integral with the insert .
  • valve insert may have two modes of use and may allow the feeding device to be suitable for a growing infant over a longer period when compared to previous feeders.
  • the mouthpiece in this embodiment could be attached to the valve insert by means of a collar.
  • the grip member is integral with or attached to an annulus which is secured between the valve insert and a threaded component, or it may be integral with or attached to the valve insert itself.
  • the device further includes means for reducing or preventing air from entering the mouthpiece to ensure that suction is unimpeded.
  • This may comprise an insert which serves to compress the mouthpiece against the tubular adaptor. However, this function may also be performed by a valve insert as described above.
  • the reservoir connection means comprises a tubular spigot to which a feed tube may be connected to provide feed from a feed reservoir.
  • the feed tube fits with the spigot by an interference fit, tightly enough to prevent an infant from disconnecting the tube, but easily enough for an adult to dissemble the two parts for cleaning.
  • the spigot is provided with a ridge to assist in securing the tube.
  • the fit provided should be strong enough to prevent an infant from dislodging the feed tube from the tubular connector, but should still allow the tube and spigot to be easily dissembled by an adult for cleaning purposes.
  • the feeding device may be provided with means for attaching a strap of a size such that it can be worn comfortably around an infant's neck. This allows the feeding device always to be readily at hand for the infant to resume feeding after an interruption or if the feeding device has fallen from the infant's mouth.
  • a kit for feeding an infant which comprises a mouthpiece adapted to deliver liquid feed to an infant, a feed reservoir, means for connecting the mouthpiece to the feed reservoir, a tube which communicates with both the reservoir connection means and the feed reservoir and a grip member shaped to be easily grasped by an infant .
  • the grip member could be attached to the mouthpiece, the feed reservoir, the reservoir connection means or the tube or could be formed as an integral part of any of these elements. If the grip member is to be attached to the tube, it is preferred that the grip member be attached to a portion of the tube which is close to or adjacent the mouthpiece or reservoir connection means. Ideally, the tube or the portion of the tube to which the grip member is to be attached is formed from a relatively rigid type of plastic in such an arrangement. The grip member may be as previously described.
  • kits for feeding an infant which comprises an infant feeding device as described above, a feed reservoir and a tube which communicates with both the reservoir connection means and the feed reservoir.
  • the reservoir comprises a receptacle for liquid feed which is provided with a closure means which includes a port through which liquid feed may pass.
  • the kit may be used in two main configurations that is, a gravity driven set up where the reservoir points downwards, and a suction setup where the infant sucks the feed from the reservoir through the feed tube.
  • a gravity driven set up where the reservoir points downwards
  • a suction setup where the infant sucks the feed from the reservoir through the feed tube.
  • the tube When the reservoir is in a gravity driven downward pointing orientation, the tube may be connected to the port in such a way that feed can flow from the reservoir through the tube to the infant feeding device.
  • a first end of the tube is connected to the reservoir connection means and a second end of the tube is connected to the port.
  • the means for connecting the port to the tube at the reservoir end of the tube is a similar spigot to that described above in relation to the reservoir connection means.
  • the spigot on the feed reservoir is formed integrally with a connector insert that is fitted in the reservoir opening.
  • the connector insert is held in the reservoir opening by means of a collar that secures it in place between the collar and the reservoir. It is yet further preferred that the collar is attached to the reservoir opening by means of a screw thread.
  • the length of feed tube can be shorter than in other uses. This is to prevent the infant from getting tangled in the tubing and potentially being hurt. Also, losses in pressure caused by narrow tubing mean that, for the gravity fed application, the tubing has to be sufficiently short to produce a meaningful flowrate of feed when the pressure head is not large.
  • the feed tube extends to the base of the reservoir so that all the feed in the reservoir can be consumed while the reservoir is in an upright position.
  • the preferred arrangement for a gravity driven set up may be converted to a suction set up by connecting a second tube, which extends to the base of the reservoir, to the port.
  • This may be conveniently achieved by using a connector insert for the reservoir which is provided with two spigots on opposite sides of the insert which define the port and fitting the tube to one spigot projecting away from the reservoir and fitting the second tube to the second spigot which projects into the reservoir.
  • the feed reservoir may be provided with means to allow air to enter the feed reservoir.
  • Such means may take the form of grooves at the opening of the reservoir such that when the reservoir is closed air can still get into the reservoir but feed cannot get out .
  • Another option is to provide a pressure relief valve in the feed reservoir. It is preferable to locate the relief valve in the lid of reservoir as the reservoir will usually be in an upright position and there is therefore less chance of fluid surrounding the valve and escaping when the valve is in operation. Consequently, the valve may be located in the connector insert, adjacent to the feed tube spigot.
  • the relief valve may comprise an aperture open to the external atmosphere and a slit valve beneath the aperture. It is preferable for the slit valve to be domed inwardly towards the interior of the reservoir and against the flow of fluid.
  • the operation of the relief valve is similar to that of the valve employed in the feeding device so that, when there is a sufficient pressure difference across the valve in a favourable direction, the valve will let air into the reservoir to equalise the pressure drop caused by the removal of feed.
  • the main valve could be located in the feed reservoir instead of in the feeding device .
  • the feeding device and/or the reservoir could be shaped in such a way that the feeding device could be located on the reservoir when not in use.
  • means could be provided for attaching the feeding device to the reservoir in such a way that feed could still flow from the reservoir to the feeding device.
  • the tube could be designed to push into the resevoir and the screw thread on the reservoir opening could be made to correspond to that of the tubular adaptor of the feeding device.
  • the mouthpiece may be directly attached to the reservoir by securing with the tubular adaptor.
  • the mouthpiece may be attached directly to the reservoir.
  • the grip member may be formed as part of a ring which fits around the thread of the reservoir opening and be held in place by either the mouthpiece or tubular adaptor when fitted on the reservoir opening.
  • the reservoir or its lid could be provided with a flange on which the feeding device may be located.
  • a hook or some form of attachment strap preferably made of velcro, be provided on the feed tube so that, when longer lengths of tubing are used, the weight of the tube is partially supported by securing the hook or strap to another fixture .
  • the reservoir may be formed with one or more tunnels in the body of the reservoir, preferably aligned in a direction generally perpendicular to the major axis of the reservoir so that the parts of the reservoir that form the surround of the tunnel can be utilised as handles.
  • the tunnels may be offset to one side of the centreline and the handles formed may be of a size such that they can be gripped by an infant.
  • the parts of the reservoir that form the handle may be hollow and joined to the central portion, hollow and empty and separated from the central portion or hollow and separated from the central portion and filled with a decorative filling such as pieces of glitter suspended in a coloured solution. Alternatively, they may be solid.
  • the handles which are separated from the central portion provide an insulated holding means.
  • Providing handles larger than the grip member of the feeding device for infants to grip the reservoir can be used as a further step in the training of an infant to use a normal cup .
  • the kit further includes means for mounting the feed reservoir on a suitable support.
  • a strap or harness may be provided which is adapted to secure the reservoir to the body of an adult, thereby releasing both hands of the adult to look after the infant while the infant feeds.
  • Another preferred feature is to provide a band that can be removably attached to the reservoir, preferably by passing the band through one or more tunnels in the reservoir as described above, there being a hook attached to the band to allow the reservoir to be hung from a suitable support.
  • the hook be rotatably attached to the band so that the bottle can be secured in any desired orientation.
  • the rotation means is biased to allow the hook to maintain an orientation that allows the reservoir to be held in a vertically down attitude or a vertically upright attitude .
  • the feed reservoir may be provided with a plurality of feeding devices so that more than one infant may feed at the same time from a single reservoir. It is envisaged that this could be particularly useful in the case of multiple births where a parent has to feed more than one infant or in the maternity ward of a hospital.

  • the reversible valve insert could be formed as part of a disc that could be inserted within the feeding device.
  • tubular connector 61 could have a tubular spigot on the base obviating the need for threads 72 and collar 85.
  • Figure 11 shows one face of the reversible valve insert 67. Valves 68, 69 only allow fluid to pass in a direction out of the page and valve 70 only allows fluid to pass in the opposite direction. These valves are shown here to be of a similar size, although they may differ in volume flowrate and activation pressure.
  • Figure 12 shows the other opposite face of the reversible valve insert 67 shown in Figure 11.
  • the maximum flowrate of fluid into the mouthpiece is reduced when compared to the orientation shown in Figure 11.
  • FIG 13 shows an embodiment of the invention in which a kit comprising a feeding device, connecting tube and reservoir is converted into a conventional training cup.
  • Grip members 77 are attached to an annulus which can fit around an externally screw threaded portion of the opening of reservoir 78.
  • a tubular adaptor in the form of internally screw threaded collar 75 which contains mouthpiece 76 is screwed onto the externally threaded portion of reservoir 78 to form a trainer cup and the connecting tube is made to slide into the body of the reservoir 78.
  • a valve insert (not shown) is also included in the feeding device.
  • a trainer cup could also be formed from the elements of Figure 10 in conjunction with a suitable reservoir. It is envisaged that this would be the penultimate stage in the training of an infant to adapt to the use of a normal cup. The final stage would be the removal of the valve insert .
  • Figure 14 shows another embodiment of a feed reservoir 79 which is provided with an alternative method of equalising the pressure inside the reservoir with atmospheric pressure when feed is being taken.
  • insert 80 is held in place at the top of the reservoir 79 by collar 81.
  • An aperture 82 is formed in insert 80 and a slit valve 83 is provided underneath the aperture 82.
  • the slit valve shown in this embodiment is domed inwardly, that is, convex in the direction of the interior for maximum prevention of leakage.
  • a flat slit valve could be used when leakage from the slit valve is of less importance.
  • the slit valve is made of a similar material to the mushroom valve and can be glued onto the underneath surface of insert 80 by a suitable non-toxic adhesive or heat welded to the insert 80.
  • the slit valve When the atmospheric pressure is above the interior pressure by a predetermined amount, the slit valve opens to equalise the pressure difference.
  • the fluid inside is prevented from escaping through the valve by the domed shape which forces the material to first compress, and thus offer more reluctance to opening, before opening to the atmosphere .
  • the materials chosen in making all parts and embodiments of this invention need to be resilient to autoclaving and chemical attack by disinfectants used in repeated sterilisation procedures. Furthermore, they need to be non-toxic and capable of use delivering paediatric medicines that can be mixed with infant feed or soft drinks. Suitable materials typically include plastics materials and silicone rubber.
  • the invention has been described in detail herein by way of example only, and many variations are possible without departing from the spirit of the invention. Particularly, it should be appreciated that features described with reference to one embodiment may be used in others.
