Definitions

  • the present invention relates to a suction nipple for milk bottles, i. Milk bottles for babies.
  • breastfeeding is the most natural and best way to feed a baby.
  • a large number of scientific studies prove that breast milk is of great importance for the baby's development.
  • the immune system is stronger, and the baby is stronger.
  • the mechanical effect of sucking on the chest has a significant effect on the development of the palate and the muscles.
  • breastfeeding is not always or only partially possible: e.g. if the mother goes back to work or is absent for breastfeeding, in case of illnesses, in case of sore nipples, or if the mother has too little milk and the baby additionally needs a substitute food.
  • the milk is pumped out and given to the baby with a bottle, a spoon, a cup or with a fingerfeeding.
  • today's teat nipples have negative effects on breastfeeding.
  • the problem is that the baby has to learn to drink at the breast. When it gets used to it and then has to drink from the bottle, it sucks for the first moment as on the chest. The baby then realizes that the nipple resp. the ratio vacuum / milk flow behaves differently.
  • the peristaltic tongue movement can not be performed to the same extent.
  • many conventional teat nipples the baby has to stop the milk flow with his tongue instead of the vacuum.
  • teat nipples are hollow inside and have holes or slits at the exit. However, the hole diameters at the outlet rarely have the optimal diameter: either the passages are too large or too small. In addition, teat nipples, which are hollow inside, do not have the correct elasticity. They are often too soft or too hard. Another weakness in today's teat cups is that there is virtually no longitudinal expansion of the mouthpiece during the suction phase.
  • WO 03/013419 discloses a suction nipple for a milk bottle with an inner and outer part, both parts being designed as flexible membranes which form a chamber between them.
  • the inner part is provided with a valve which controls the flow of milk from the bottle into the chamber.
  • the outer part has at its top an opening through which the baby can suck the milk out of the chamber.
  • the two parts are shaped so that when squeezed or sucked on the outer part of the valve is closed and when unloading the outer part of the valve is opened.
  • WO 02/22073 shows a two-piece teat for a drinking cup, in which case the inner part acts as a valve. At rest, the inner part presses spring-loaded up against the opening of the outer part, so that the teat is tight. If pressure is exerted, the inner part sinks down and releases the opening of the outer part. Now, when the outer part is compressed, it lies close to the side walls of the inner part, in the unloaded state, however, it releases through channels to the cup.
  • BE 381523 describes a suction bottle with a teat and an intermediate plate to be arranged between the bottle and nipple.
  • This intermediate plate has capillaries to regulate the flow of milk.
  • GB 2 370 787 discloses a suction bottle with a valve arranged in the suction nipple, which is intended to regulate the flow of milk.
  • the inventive suction nipple for milk bottles has a receiving head made of a dimensionally stable material and an absorbent body made of a rubber-elastic material, wherein the receiving head is formed as the core of the teat and the absorbent body is slipped over the receiving head, wherein the absorbent body a mouthpiece and an outlet channel extending therein Milk, so that when the negative pressure generated in the mouthpiece milk from the milk bottle can get into the outlet, the absorbent body in a basic position with an inner surface sealingly bears against at least a portion of an outer surface of the receiving head.
  • This teat nipple is characterized by capillary milk channels which are present in this contact area of the absorbent body with the receiving head and which lead in the direction of the outlet channel extending in the mouthpiece, so that when generated in the mouthpiece negative pressure milk from the milk bottle through the milk channels flow into the outlet channel can, with no negative pressure of the absorbent body is moved back to its normal position and the milk flow is interrupted.
  • an inlet channel leading to the interior of the bottle and at least one channel emerging from it to the outer surface of the receiving head are provided in the receiving head.
  • the milk channels communicate with the at least one channel of the pickup head.
  • the milk channels are arranged in the inner surface of the absorbent body and / or in the outer surface of the receiving head, wherein they are each open to the other surface
  • the milk channels are designed as capillaries. Under capillaries narrow channels are understood in which surface forces are effective, so that no milk flows without generated vacuum.
  • an inlet channel leading to the interior of the bottle is provided in the receiving head.
  • This teat is characterized by at least one channel which is provided in the receiving head and which exits from the inlet channel to the outer surface of the receiving head in the contact area of the absorbent body, so that when the negative pressure generated in the mouthpiece milk from the milk bottle can flow through the milk channels in the outlet channel, the absorbent body is moved back into its normal position and the milk flow is interrupted without negative pressure ,
  • the functionality is essentially the same as the typical breastfeeding on the human breast.
  • a vacuum is created and milk from the bottle between the outer surface of the Receiving head and the inner wall of the absorbent carried through to the exit.
  • the natural sucking consists essentially of the functions or the parameters: suction strength, sucking rhythm, tongue movement, supporting the lips and pressure on the nipple, and areola.
  • the teat according to the invention now makes possible an overall system which simulates all essential still functions or parameters. For example, if no vacuum and no pressure is produced by the baby (by means of lips or tongue), no milk is released. If the nipple is compressed without creating a vacuum, there will be no milk delivery. Only when vacuum and pressure are generated on the nipple, the milk flows. The amount of milk can thus be controlled by the vacuum level, suction rhythm and by the pressure of the tongue and lips.
  • the nipple feels soft and flexible. It is preferably made of a resilient solid material, which expands in the longitudinal direction under vacuum - similar to the nipple.
  • the lip support is adaptable and elastic.
  • the vacuum / milk flow behavior is comparable to the milk flow of the human breast.
  • the inventive teat is also inexpensive to produce and it can be optimally cleaned.
  • the mouthpiece By sucking on the mouthpiece and the peristaltic tongue movement, a vacuum is created.
  • the mouthpiece In vacuum construction and by the tongue movement, the mouthpiece is deformed and extended axially.
  • the lip support deforms, so that the nipple in baby's mouth is sucked far towards the palate.
  • the absorbent body lifts off from the receiving head in the region of the milk channel closure wall and opens the passage to the outlet channel.
  • the milk flows from the bottle through any milk channels and through any milk chambers to the outlet channel.
  • the milk channels are lying between the outer surface of the receiving head and the inner wall of the absorbent body.
  • the task of the milk channels is to dispense the milk from the bottle in proportion to the sucking behavior of the baby.
  • the capillary cross-sections and capillary lengths determine the milk flow in relation to the vacuum level.
  • the milk chambers are used by the mother to visually monitor whether there is no air in the system to prevent the baby from swallowing air while drinking.
  • the milk chambers are thus optional.
  • the actual absorbent body consists in a preferred embodiment of a soft elastic silicone outer part and a harder silicone inner part, which are preferably prepared by multi-component injection molding and are permanently connected to each other.
  • the outer soft part of the absorbent body can preferably be felt and deformed similar to the nipple and the areola.
  • the inner harder part of the 2-component silicone absorbent body gives the absorbent the necessary stability.
  • the inner part of the absorbent body is used in addition to the stabilization especially the protection against a possible biting through in the region of the elastic mouthpiece.
  • the inner part is shown in the region of the mouthpiece as a cylindrical tube.
  • through-bite protection other geometric shapes or materials such as e.g. a spiral or a tissue insert in question.
  • the flow speed depends on the vacuum. With a small vacuum little milk flows, at higher vacuum accordingly more. No matter which vacuum suction curve the baby pretends, the system adapts. For example, a baby can keep the vacuum at a high level for a long time, and the milk flows constantly. As soon as the vacuum is reduced, the milk flow is reduced. If no vacuum is exerted on the nipple between the suction phases, the absorbent body rests on the milk channel closure wall and closes the outlet. Thus, the suction nipple system adapts to the suckling behavior of the baby at any stage, no matter how long the baby keeps the vacuum upright. The milk is delivered according to the suction behavior.
  • the natural breastfeeding can be further promoted because the baby is not confused by the teat and thus no longer the risk that the breastfeeding is terminated early.
  • the invention described below relates to a teat for milk bottles or a hydration system for infant feeding.
  • the system consists of a suction body 1 made of rubber-elastic material, such as silicone, and a form a receptacle for the absorbent body 1 forming dimensionally stable or rigid Distributor head or receiving head 2, here with an integrated threaded flange or threaded ring 203 for releasably screwing the receiving head 2 on a milk bottle 3.
  • the receiving head 2 is preferably made of a rigid plastic by injection molding. For example, it is made of hard plastic.
