Abstract

The invention relates to a spoon for receiving soft or liquid food. Said spoon has a handle with an attached mouthpiece constructed of soft and flexible material. The aim of the invention is to significantly simplify the manner in which food is received by small children and people with facial paralysis. The spoon has a practical shape in that the mouthpiece is trough-shaped and concave and has a level defining upper edge, whereby the thickness of the mouthpiece in the front and on the lateral side is proportional so that its concave shape can be inverted by the pressure of the tongue (Z) during swallowing and the mouthpiece can adapt to the arched shape of the hard palate (G) in a sagital and transversal direction.

Description

Die Erfindung betrifft einen Eßlöffel zur Aufnahme breiiger oder flüssiger Nahrung mit einem Griff und einem sich daran anschließenden wannenförmigen, konkav ausgebildeten Mundteil aus weichem und flexiblen Material.The invention relates to a tablespoon for intake mushy or liquid food with one handle and one adjoining trough-shaped, concave trained mouth part made of soft and flexible Material.

Aus der US-2 295 847 A ist ein derartiger Löffel bekannt, der an einem stark gebogenen Griff ein wannenförmiges, konkav ausgebildetes Mundteil aus weichem und flexiblen Material trägt, wobei der Griff zur Erhöhung seiner Biegesteifigkeit eine feste Einlage aus Metall benötigt, die den Löffel erheblich verteuert.Such a spoon is known from US Pat. No. 2,295,847 A, which has a tub-shaped, concave mouthpiece made of soft and flexible Material carries, the handle to increase its Bending stiffness requires a fixed insert made of metal, which makes the spoon considerably more expensive.

Mit diesem bekannten Kinderlöffel soll erreicht werden, daß dieser aufgrund des weichen Materials von den Kindern besser angenommen wird, weil sie an den Kontakt mit weichen Gegenständen gewöhnt sind. Außerdem soll erreicht werden, daß dieser bekannte Kinderlöffel der Konformation und den Bewegungen des Kindermundes besser angepaßt wird und daß Verletzungen durch das Mundteil, zum Beispiel durch Stöße auf die Zähne oder die Lippen, verhindert werden.With this well-known children's spoon that this is due to the soft material from the children is better accepted because of the contact with are used to soft objects. It also aims to achieve be that well-known children's spoon of conformation and better adapted to the movements of the child’s mouth and that injuries from the mouthpiece, for example by bumping your teeth or lips become.

Bei diesem bekannten Löffel handelt es sich um eine tiefe Schaufelform, deren Breite etwa dem Doppelten der Tiefe entspricht, das heißt, der Querschnitt in der Mitte des Mundteils stellt einen Halbkreis dar. Ein derart tiefer Löffel kann nicht durch den Druck der Zunge in eine konvexe Form umgestülpt werden, so daß die Nahrung auch nicht auf diese Weise vom Löffel heruntergepreßt werden könnte. Auch kommt die Zunge beim Schluckversuch, solange der Löffel im Mund verbleibt, nicht nahe genug an den Gaumen heran, um den Schluckreflex auszulösen.This known spoon is a deep one Shovel shape, the width of which is approximately twice the depth corresponds, that is, the cross section in the middle of the Mouth part represents a semicircle. Such a deep one Spoon cannot press the tongue into one convex shape can be turned inside out so that the food too not be pressed off the spoon in this way could. The tongue also comes when trying to swallow, as long as the spoon remains in the mouth, not close enough to the Palate to trigger the swallowing reflex.

Um die Nahrung, die sich auf dem Löffel befindet, in der Mundhöhle zurückzuhalten, ist die Wirkung mimischer Muskulatur (Facialis-Muskulatur), hauptsächlich des Musculus orbicularis oris (Ringmuskel um die Mundöffnung), notwendig. Damit wird das Mundteil des Löffels am Übergang zum Handgriff abgedichtet. Gleichzeitig kann der Löffel aus der Mundhöhle gezogen werden, wobei die Nahrung in der Mundhöhle verbleibt. Der Schluckvorgang folgt anschließend.To the food that is on the spoon in the Restraining the oral cavity is more mimic Muscles (facial muscles), mainly the Orbicularis oris muscle (ring muscle around the Mouth opening), necessary. So that the mouth part of the Spoon sealed at the transition to the handle. At the same time, the spoon can be pulled out of the oral cavity with the food remaining in the oral cavity. The Swallowing follows.

Für Personen, deren Facialis-Muskulatur nicht oder nur eingeschränkt funktionsfähig ist, ebenso für solche Personen, die den motorischen Ablauf der Facialis-Muskulatur für die oben beschriebene Nahrungsaufnahme noch nicht erlernt haben bzw. dazu nicht imstande sind, wird die Nahrungsaufnahme mit dem bekannten Löffel, auch bei fremder Hilfestellung, schwierig oder unmöglich.For people whose facial muscles are not or only has limited functionality, as well as for such Individuals who control the motor flow of the facial muscles for the food intake described above have not yet learned or are unable to food intake with the well-known spoon, too with outside help, difficult or impossible.

Zu diesem Personenkreis zählen beispielsweise Säuglinge, die ihre Nahrung bislang nur durch Saugen an der Mutterbrust oder an der Flasche aufgenommen haben, sowie Personen mit Facialis-Lähmung nach einem Unfall oder Schlaganfall oder mit sonstiger, zum Beispiel durch Krankheit bedingter Facialis-Lähmung oder Einschränkung der Facialis-Funktion.This group of people includes, for example, infants, who have so far only been able to suckle their food Mother's breast or on the bottle, as well People with facial paralysis after an accident or Stroke or with other, for example through Facial paralysis or limitation due to disease the facial function.

Der Erfindung liegt die Aufgabe zugrunde, einen Eßlöffel der eingangs erwähnten Art so zu gestalten, daß die Nahrungsaufnahme für den zuvor genannten Personenkreis wesentlich erleichtert bzw. erst praktikabel gestaltet wird, indem seine konkave Form durch den Druck der Zunge in eine konvexe Form umgestülpt und das Mundteil der Bogenform des harten Gaumens in sagittaler und transversaler Richtung angepaßt wird, so daß die Zunge so nahe an den Gaumen herankommt, daß der Schluckreflex ausgelöst werden kann, während der Eßlöffel sich noch im Mund befindet.The invention has for its object a tablespoon of the type mentioned at the outset so that the Food intake for the aforementioned group of people much easier or only designed practically is made by its concave shape due to the pressure of the tongue turned into a convex shape and the mouth part of the Arch form of the hard palate in sagittal and transverse direction is adjusted so that the tongue so that the swallowing reflex comes close to the palate can be triggered while the tablespoon is still in the Mouth.

Diese Aufgabe wird gemäß dem Anspruch 1 dadurch gelöst, daß der Begrenzungsrand des Mundteils und die Längsachse des Griffs in derselben Ebene liegen und daß die größte, mit 24 mm bemessene Breite des Mundteils gleich dem Vierfachen seiner größten Höhe ist, während die Materialstärke des Mundteils in Richtung zur Spitze hin von 2 mm in der Nähe des Griffs auf 1,3 mm in der Mitte und bis auf 1,2 mm im vorderen Drittel abnimmt und daß seine konkave form beim Schluckvorgang durch den Druck des Zunge (Z) in eine konvexe Form umstülpbar ist und das Mundteil der Bogenform des harten Gaumens (G) in sagitales und transversales Richtung anpaßbar ist.This object is achieved according to claim 1 that the boundary edge of the mouthpiece and the longitudinal axis of the handle are in the same plane and that the largest, with a width of 24 mm Mouth part equal to four times its maximum height while the material thickness of the mouthpiece is towards to the tip of 2 mm near the Grips to 1.3 mm in the middle and up to 1.2 mm decreases in the front third and that its concave shape when swallowed by the pressure of the Tongue (Z) can be turned into a convex shape and the mouthpiece the arch shape of the hard palate (G) into sagital and transverse direction is adjustable.

Um eine einfache und kostengünstige Herstellung des Eßlöffels zu ermöglichen, ist nach einer Weiterbildung der Erfindung vorgesehen, daß das Mundteil zusammen mit dem Griff einstückig hergestellt ist. To make the production of the Enabling tablespoons is after further training the invention provided that the mouthpiece together with the handle is made in one piece.
