Definitions

  • the invention relates to a teat unit according to the preamble of patent claim 1.
  • EP 1 532 957 discloses a teat with a large suction port and a flow restrictor arranged in the mouthpiece. Also in US 5,101,991 and BE 3 81523 the flow restrictors protrude into the mouthpiece.
  • EP 0 384 394 describes a teat with a first flow restrictor with a large opening and a suction port as a second flow restrictor with a smaller cross-section.
  • WO 2007/137440 In WO 2007/137440 .
  • WO 2007/137436 and WO 2007/137885 are shown relatively stiff, hardly deformable mouthpieces.
  • WO 03/013419 describes a relatively small suction opening and a larger passage opening outside the mouthpiece.
  • the passage opening is provided with a check valve.
  • US 5,791,503 shows a relatively complex teat unit with a check valve.
  • GB 347,368 discloses a teat with a suction port and a flow restrictor with a smaller passage opening.
  • the flow restrictor is located outside the mouthpiece.
  • US 3,207,349 shows a teat with a one-way valve, which closes a passage opening.
  • the suction opening is described as a slot.
  • the inventive teat unit for sucking a liquid from a liquid container has a teat and a flow restrictor with a through hole.
  • the suction nipple has a mouthpiece with a suction opening, from which liquid emerges from the mouthpiece to the outside, and an integrally formed on the mouthpiece, extending towards the mouthpiece body.
  • the flow restrictor determines a maximum flow from the liquid tank through the suction opening flowing liquid.
  • the flow restrictor is arranged outside the mouthpiece, and the suction opening has a larger cross-sectional area than the passage opening of the flow restrictor.
  • the mouthpiece also called nipple
  • the mouthpiece can be deformed well during the suction process and it optimally adapts to the movements of the baby's mouth and tongue.
  • the infant gets a similar sensation in the mouth as if it were sucking on a natural nipple of a mother's breast.
  • the mouthpiece is bendable and, in intended use, preferably does not project any parts stiffening the mouthpiece over a substantial part of its length into it. In the intended use, the mouthpiece is therefore preferably deformable.
  • a milk channel between the suction opening and the flow restrictor which also has at least one diameter of the same diameter as the diameter of the suction opening. If several milk channels are present, then they have at least in common over their entire length a flow opening which is larger than that of the flow restrictor and which preferably corresponds at least to the diameter of the suction opening.
  • the inner diameter of the milk channel over its entire length is approximately the same size as the suction opening. There is no further flow restriction in the area between the flow restrictor and the suction opening, which would limit the flow more or only approximately the same as the first mentioned flow limiter.
  • the mouthpiece is formed as flexible as possible.
  • the total cross-sectional area of the suction opening is many times greater than the entire cross-sectional area of the passage opening of the flow restrictor.
  • Typical diameters for the suction opening are 3 to 8 mm and for the flow restrictor 0.2 to 0.7 mm.
  • the mouthpiece can have the same softness and flexibility over its entire length. In a preferred embodiment, however, it becomes harder and / or stiffer towards the main body. Depending on the embodiment, this is done continuously or stepwise. This change can be done, for example, by increasing the wall thickness.
  • the suction opening and / or the adjacent milk channel may have a round, oval or elliptical cross section. They can be designed rotationally or mirror-symmetrically. However, they can also have an asymmetrical shape. The same applies to the outer shape of the mouthpiece. For example, it can have a round cross-section over its entire length or, in particular, it can have a tooth-like shape (called a dental mold).
  • the flow restrictor may be molded in the teat itself or it may be in another separate part of the teat unit. However, the flow restrictor is located outside the mouthpiece, i. outside of that part which is put into the mouth by the infant in the intended use. As a result, the infant can not influence the flow restrictor by mechanical pressure or tension caused by his lip and mouth movements.
  • a teat unit for sucking a liquid from a liquid container. It has a teat and a flow restrictor with a through hole.
  • the teat has a mouthpiece with a suction opening and a molded on the mouthpiece, widening towards the mouthpiece Body on.
  • the flow restrictor determines a maximum flow of liquid flowing from the liquid container from the suction port.
  • the flow restrictor is arranged outside the mouthpiece and the teat unit has a one-way valve, which is arranged outside the mouthpiece, wherein the flow restrictor is arranged in the one-way valve or in an adjacent area thereto.
  • a large suction opening is also an advantage here, but not absolutely necessary.
  • the mouthpiece in this case, reinforcing elements, such as ribs have.
  • it is formed single-walled and / or unreinforced.
  • suction unit In this suction unit is only atmospheric pressure or negative pressure. There is no overpressure. The milk thus does not splash into the baby's mouth, but flows into the mouth according to the vacuum applied by the baby. The milk flow is approximately proportional to the vacuum applied by the infant.
  • This Saugnippelü allows a suction, which is purely vacuum-controlled and largely independent of the rest, in particular the peristaltic movement of the tongue. If the posterior region of the tongue moves towards the upper palate, no milk should flow. If this rear area moves away from the upper palate, the milk flows.
  • the inventive Saugnippelritt takes into account the knowledge that the baby does not switch back and forth between vacuum and atmospheric pressure when sucking. It rather maintains a base vacuum throughout the suction process.
  • the valve now closes upon reaching this base vacuum. If the absolute value of the applied vacuum rises above this basic vacuum, the valve opens and the milk or liquid can flow. The baby is thus able to take a break despite being able to maintain the basic vacuum, to take a breath or to recover, and to gather new strength, as happens with the mother's breast.
  • the device according to the invention opens even at a low negative pressure of 1 to 90 mmHg, preferably 20 to 70 mmHg. Even more preferred values are between 20 to 30 mmHg and 5 to 30 mmHg. These values are in theirs Absolute amount just above a typical base vacuum of a baby.
  • valve has no further influence on the milk flow during the suction process.
  • the degree of opening and operation of the valve does not affect the flow of milk through the suction port.
  • the check valve covers the passage opening of the flow restrictor. In a preferred embodiment, however, the check valve does not cover the relatively small passage opening of the flow restrictor but a larger opening.
  • This opening is preferably arranged in the flow direction of the liquid in front of the flow restrictor, i. So directed to the liquid container. However, it can also be arranged downstream of the flow restrictor in the direction of flow.
  • the opening of the flow restrictor is in the rigidly formed valve seat, i. here in the base part.
  • this opening can be covered and closed by the valve membrane.
  • it can also be arranged adjacent and lead into the dead volume.
  • the opening of the flow restrictor can be arranged in the valve membrane and closed by sealing support of the membrane on the valve seat.
  • the outflow opening is arranged adjacent to the valve seat and is not closed by the membrane but leads into the dead volume.
  • the outflow opening can be made the same size or larger than the opening of the flow restrictor.
  • the flow restrictor can thus be arranged in, above or below the valve diaphragm be.
  • valve and the flow restrictor or the outlet opening and the valve are arranged adjacent to each other, the dead volume, in which also a vacuum must be generated, minimized.
  • the valve or vacuum works perfectly even at low flow rates.
  • the valve is easy to disassemble and therefore easy to clean the teat unit. If a membrane is used, it can be held by clamping between individual parts.
  • an umbrella valve instead of a clamped membrane with or without a well-defined opening cross-section, an umbrella valve, a beak valve or a slotted membrane can also be used.
  • the suction opening has a larger cross-sectional area than the passage opening of the flow restrictor.
  • the milk channel between the flow restrictor and the suction opening over its entire length has a cross-sectional area which is greater than that of the passage opening and preferably corresponds at least to the size of the cross-sectional area of the suction opening.
  • the suction opening may also have an equal cross-sectional area as the flow restrictor. The same applies to the milk channel.
