Definitions

  • the invention relates to a suction nipple according to the preamble of patent claim 1.
  • an infant drinks from the mother's breast.
  • attempts have been made to develop nipples for baby bottles, which allow the infant as possible a nature-inspired sucking.
  • the infant should be able to switch back and forth between mother's breast and feeding bottle without any confusion.
  • emphasis is placed on the fact that the infant can not interrupt the flow of milk unintentionally by pressing the mouthpiece of the teat too tightly.
  • teat nipples was also in the foreground that the teat does not cause permanent damage in baby mouth.
  • US 1 590 152 to replace the previously used long nipple teat with a nipple, which can hardly be extended by the infant.
  • teat nipples are known, which have a hollow nipple, wherein the mouthpiece is provided with a thicker wall, so that it does not completely collapse when sucking.
  • US 1 605 427 discloses a teat, the mouthpiece with a hollow cylindrical Insert part is reinforced. The insert has radial ribs on its inside. This insert is intended to prevent the mouthpiece from being pressed together so that milk can no longer flow.
  • U.S. 4,586,621 shows a teat with a semi-rigid inner membrane and a thin elastic outer membrane. This outer membrane is filled with milk when sucking over the opening in the semi-rigid membrane and therefore swells.
  • US 5,101,991 shows a teat, the mouthpiece is double-walled.
  • the inner wall forms a hollow cylinder, which runs concentrically to the central axis of the mouthpiece and hangs down freely. Downwards, against the suction bottle, this hollow cylinder is formed closed except for a small passage opening.
  • JP 2002011076 Ultrasound images were used to examine how the natural sucking behavior of an infant looks effectively. It is proposed to provide a suction nipple whose mouthpiece has zones of increased extensibility. This nipple thus gets deeper into the palate area of the child, similar to the nipple in the natural breastfeeding of the infant.
  • the mouthpiece is provided in addition to these zones of increased extensibility with axially extending ribs, which allow a milk flow even with squeezed nipple.
  • an inner hollow cylinder projecting in the direction of the milk bottle is formed.
  • US Pat. No. 6,966,904 discloses a teat with a milk channel running in the teat, which is formed by a separate tube.
  • a variant is disclosed in which the inner milk channel is formed integrally with the teat. Both teat cups have a valve to regulate the flow of milk.
  • GB 7179 and GB 934 534 disclose teat cups with an outer and inner wall, between which two walls a hollow, self-contained Chamber is formed.
  • the nipple and the chamber change their shape during sucking. These nipples are to avoid later deformities of the child's teeth or convey the same elasticity as the mother's breast.
  • the inventive nipple takes into account the natural interaction of the palate, tongue and nipple. Since the teat has an air space or a chamber which inflates cyclically during suction, the teat similar to the nipple of the mother can follow the tongue and / or palate movement of the infant and optimally fill the mouth similar to the nipple of the mother.
  • the air space does not only inflate in the direction perpendicular to the longitudinal axis of the suction nipple. Thanks to its three-dimensional enlargement, the mouthpiece of the teat is extended and extends to the soft palate of the child.
  • the inventive teat nipple allows a lifelike reproduction, so that Saugverwirrung can be avoided when changing from teat to the natural mother's breast.
  • the teat according to the invention has a main body with an inlet opening and a mouthpiece with a suction opening and with at least one suction channel extending from the inlet opening to the suction opening.
  • the mouthpiece has at least one expandable zone, which runs separately from the at least one suction channel and which lies in use between the palate and the tongue of an infant.
  • This zone is designed so that it expands, in particular inflates, at a negative pressure which is produced by the infant during its sucking in its mouth.
  • This expansion is preferably reversible, so that the zone expands cyclically during suction and in accordance with the suction rhythm and reduces its volume again.
  • the mouthpiece in particular the suction channel, formed bendable soft.
  • the suction channel is approximately as soft as or even softer than the outer wall of the mouthpiece.
  • the mouthpiece in use, has an upper side facing an infant's palate and a lower side facing a tongue of the infant, having at least one double walled wall on its upper side and at least one zone between them two walls is arranged.
  • This zone is preferably a chamber which is open or closed with respect to the main body or a space which is filled with air, a gas, a liquid or a foam. If the chamber is filled with foam, then it is either itself expandable under reduced pressure or it has gas, in particular air, filled chambers which expand under reduced pressure.
  • the inventive suction nipple has a base body, a mouthpiece with a suction opening and at least one extending from the base body to the suction opening suction or milk channel.
  • the mouthpiece has an outer wall closed in the circumference and an inner wall adjoining the outer wall in the region of the suction opening and closed on the circumference, wherein the inner wall forms the at least one milk channel on its inner side directed towards its longitudinal center axis.
  • the at least one air space extends separately from the at least one suction channel, wherein it has spacers.
  • the inventive nipple takes into account the interaction of the palate, tongue and teat.
  • it allows the teat to lie fully against the infant's palate during its sucking phase, in which the posterior region of the tongue is lowered, with virtually its entire upper surface.
  • the teat nipple abuts virtually the entire lower surface of the tongue of the infant.
  • Ultrasound scans of a breast-fed baby have shown that the baby is cyclically switching back and forth between two sucking phases.
  • a phase A the back of the baby's tongue is raised and presses against the hard palate.
  • a phase B this rear tongue area is lowered.
  • the ultrasound images have also shown that the nipple is stretched to just before the transition from the hard to the soft palate.
  • the infant creates a negative pressure in the mouth by moving its tongue downwards in phase B in phase B.
  • the upper lip on the one hand and either the tongue and / or the lower lip on the other hand form a sealing closure against the outside.
  • the soft palate of the baby helps to maintain the negative pressure during sucking.
  • the soft palate forms a throat-side seal to maintain the vacuum in the oral cavity.
  • the nipple In phase A, the nipple has a coronal cross-section in the shape of an ellipse, with the major half-axis aligned. In phase B, the nipple is preloaded by the maximum vacuum and has an approximately round cross-section. The cyclic movement of the tongue up and down thus changes the diameter of the nipple in the same cycle. The coronal cross section cyclically changes its shape, the cross-sectional area in phase B being rather reduced compared to phase A. This effect forms the inventive Teat now after.
  • the at least one air chamber of the suction nipple which preferably has atmospheric pressure, inflates at an external negative pressure. This enlarges the outer diameter like the nipple.
  • the air chamber changes its volume in the same cycle as the baby raises and lowers the tongue. If at least the upper side of the teat is provided with such an air chamber, it is ensured that the teat during phase B rests like the nipple on the hard palate of the baby.
  • the air space may be formed open to the main body.
  • This embodiment is simple and therefore inexpensive to produce.
  • at least one or all of these air chambers may also be formed closed relative to the main body. This embodiment ensures that in any case the balloon effect is fully achieved, i. the chamber inflates.
  • the at least one air space extends annularly around a longitudinal central axis of the mouthpiece and is therefore also located on the lower, the tongue of the baby facing side of the teat.
  • the air space may extend only over part of the length of the mouthpiece. Preferably, however, it extends over the entire length. It is also possible that several air spaces are distributed over the length of the mouthpiece arranged one above the other, these air spaces are completely separated from each other and do not allow mutual exchange of air. However, they can also be designed so that an air exchange is possible.
  • milk channels there may be several milk channels. Preferably, however, there is a single milk channel which runs coaxially along the longitudinal central axis of the mouthpiece.
  • spacers for example ribs, are arranged in the air space, which retain this air space in a reduced form when the mouthpiece is compressed. This prevents the walls of the mouthpiece from sticking to one another and the air space from being unable to inflate during the next cycle.
  • the spacers are projections which are arranged on at least one of the walls of the mouthpiece and directed towards the air space. But it can also be grooves.
  • the projections can run at a constant height.
  • its longitudinal direction extends in the axial direction. In a preferred embodiment, they extend over approximately the entire length of the air space.
  • the inventive, easy to manufacture and easy-to-clean embodiment has an outer wall closed in the periphery, one in the region of the suction opening to the outer wall subsequent, circumferentially closed inner wall and a subsequent to the free end of the inner wall flange.
  • the inner wall forms on its side directed towards its longitudinal central axis inside the at least one milk channel.
  • the flange is directed radially outwardly away from the inner wall. He is, for example, sealingly suspended in an opening of a receiving head of a Saugnippelvenez to form the at least one separate air space between the outer wall and inner wall.
  • FIG. 1 shows a schematic representation of the sucking behavior of a baby.
  • the reference numeral 9 denotes the mouth of the baby, 90 shows his upper lip.
  • 91 denotes its hard palate and 92 its soft palate.
  • the baby's tongue is labeled 93.
  • a mouthpiece 12 of a teat 1 according to the invention is located in the mouth 9 of the baby.
  • the front part of the tongue 93 and / or the lower lip on the one hand and the upper lip on the other hand surround the teat 1 sealingly against the outside.
  • the mouthpiece 12 protrudes almost into the mouth 9 until the transition of the hard palate 91 into the soft palate 92.
  • the front part of the tongue 93 presses from below against the mouthpiece 12, wherein the rear part of the tongue 93 is lowered. It creates a cavity 94 in the rear, whereby a negative pressure in the mouth 9 is generated.
  • This zone 14 is preferably a chamber filled with a fluid or an air space.
  • the following is spoken of airspace instead of zone.
  • Other types of zones are equally feasible.
  • the space instead of being filled with air, the space may be filled with another gas, with a liquid or with a foam.
  • the air space 14 is located on the hard palate 91 substantially over its entire length. In the example shown here, since the air chamber 14 extends substantially over the entire length of the mouthpiece 12, the mouthpiece 12 lies on the hard palate 91 over its entire length.
  • the lower portion of the double-walled mouthpiece 12 is compressed, wherein Here, too, a front airspace 15 is present. However, this does not necessarily have to be present. As in FIG. 1 can be seen, the bottom of the mouthpiece 12 preferably hugs the tongue 93.
  • a running in the mouthpiece 12 milk channel 18 is shown here almost completely closed. This does not necessarily have to be the case. However, the milk flow is largely interrupted in this situation.
  • a suction opening of the suction nipple 1 is provided with the reference numeral 13.
  • FIGS. 3a and 3b Now the situation is shown in which the tongue 93 is raised back.
  • the lower air space 15 is reduced or disappears depending on the design of the mouthpiece 12 completely.
  • the pressure on the lip-side part of the mouthpiece is slightly reduced.
  • the upper air space 14 is compressed, but still exists with reduced volume.
  • Reason for this are spacers, which are arranged in the air space 14. These spacers will be described later in the text.
  • the upper air chamber 14 and the upper part of the mouthpiece 12 are still on the hard palate 91 at. The same applies to the lower part of the mouthpiece 12, which also bears against the tongue, not shown.
  • At least on the top of the mouthpiece 12 at least one upper air space 14 is present.
  • On both sides also several air spaces can be present.
  • the upper and lower air spaces 14, 15 may be connected to each other or even formed by the same space, so that the mouthpiece 12 is rotationally symmetrical.
  • the air spaces 14, 15 preferably have atmospheric pressure. They may be open and thus communicate with the outside of the teat 1. As in the FIGS. 1 and 2 can be seen, the lip 90, the hard palate 91 and the tongue 93 closes off the air spaces 14, 15 preferably to the outside.
  • the air spaces 14, 15 may also be formed closed. In this case they may also have an overpressure relative to the atmospheric pressure or a negative pressure as long as this underpressure is substantially smaller (i.e., closer to atmospheric pressure) than the negative pressure generated in the baby's mouth.

Due to the axial displaceability of the base part 3, the flange 11 is released and the teat 1 can be removed from the receiving head 2. Subsequently, the plug connection between receiving head 2 and base part 3 can be released. The three parts can now be cleaned as individual parts and sterilized if necessary.
  • the teat according to the invention makes possible an interaction of the palate, tongue and teat which is modeled on natural breastfeeding.
