Description

ARTIFICIAL BREASTFEEDING SYSTEM

Field of the invention

The present invention relates to the field of childcare, and more particularly the field of breastfeeding children from 0 to 6 years. The present invention more particularly relates to an artificial feeding system. The present invention therefore relates to a bottle, comprising a nipple and a reservoir on which the nipple can be adjusted by means of a retaining ring, and a reservoir holder comprising a strap adapted to support the bottle of the bottle, the combination of these two objects forming the artificial feeding system according to the invention.

The pacifier according to the invention is particularly designed to be adapted to the anatomy of children, and allows the natural muscular work of breastfeeding.

The Applicant has investigated the causes of maxillofacial development disorders, the frequency of which increases in modern society. Studies have shown the direct link between these disorders and two elements: breastfeeding and modern nutrition (Nutrition and physical degeneration, 6th Ed, Keats Publishing, 1997).

Breastfeeding is a natural and essential stimulus, both psychological and muscular, for the child during his first year of life. For example, in its first year, the child absorbs about 300 liters of milk and performs more than 3 million feedings, thus more than 3 million cranio-facial development stimuli, in addition to the stimuli of non-feeding. nutritious. It is known that breastfeeding promotes normal bone growth in the facial area, and does not lead to malocclusions (Evidence of long-term effects of breastfeeding, WHO 2007, The importance of breastfeeding as it relates to total health, Dr. Brian Palmer 2002, breastfeeding file No. 42, lllfrance.org). However, artificial feeding is predominant today and has become a social reality. However, American and Australian studies (Labbok & Hendershot 1987, Davis & Bell 1991) show that the use of current nipples leads to a 32.5% malocclusion rate at 3 years of age and 89% for malocclusions. children aged 12 to 17, showing that pacifiers currently marketed are a drag on growth normal newborn. In 1999, the additional health expenditure (outpatient care and hospitalization) related to artificial feeding with unsuitable teats of the prior art is estimated at 170 million euros in France (according to Bail & Wright studies). , 1999). Good breastfeeding has become a public health issue.

State of the art

In the state of the art, it is proposed some artificial feeding devices designed to prevent the development of maxillofacial disorders. There may be mentioned for example WO2004 / 026219, which describes a pacifier intended to maintain a normal dentition and a normal development of the jaw in a child. This pacifier comprises a bulb, an isthmus less thick than the thickness of the anterior teats, and a skirt. WO2004 / 026219 specifies that, since the isthmus extends from the outer skirt to the bulb, this pacifier prevents the child from developing malocclusions (see WO2004 / 026219 page 4 line 35-page 5 line 3).

Some devices attempt to replicate or mimic breastfeeding: for example, US 6,645,228 and US 6,745,912. In US 6,645,228, the upper part of the pacifier, namely the areola and the nipple, can be moved under the action of the baby's sucking, because the lower part has a thinned region which behaves like a spring. In US 6,745,912, it is grooves formed on the inner part of the nipple that allow a stretching of the nipple.

However, in these two devices, the movements of the areola and the extremity do not really imitate the movement of natural breastfeeding. US 3,082,770 describes an asymmetric pacifier comprising a constricted isthmus, and a concave areola in its lower part and convex in its upper part, requiring pressure work on the part of the child during feeding. Nevertheless, this specific conformation of the pacifier does not make it possible to faithfully reproduce the natural work of breast feeding. Indeed, the movement of the tongue induced by the nipple of US 3,082,770 is a piston movement against the palate, with a tongue in the posterior position, which generates a deformation of the palate. On the contrary, the natural movement of the tongue during feeding is a peristaltic movement. In addition, the posterior position of the language induced by the nipple of US 3,082,770 prevents proper posterior closure of the oral cavity, which generates otitis and false-road phenomena.

WO 2004/010921 discloses an asymmetric teat, allowing thanks to the material of which it is formed, and the presence of specific means, including air inlets, on the nipple, to reduce the effort of the feed, including eliminating breathing difficulties for the child. However, the technical means implemented by this pacifier are totally different from those of the present invention. In addition, pacifiers and lollipops sold commercially, and which have the name "orthodontic" or "physiological" do not have any medical validation to support these names. Studies have shown that there is no significant difference between so-called physiological pacifiers and lollipops and conventional pacifiers (Evaluation of the effects of orthodontic pacifiers on the lacteal dentition of children aged 24 to 59 months, Adair & Milano & Dushku).

Currently none of the teats on the market allows the natural muscle function of feeding: the baby performs on these pacifiers classic pressure of the tongue to the palate with a piston movement and significant intra-oral depression related to an abnormal effort of musculature cheek. The disruption of the natural function has repercussions in the medium term on the growth of the child and ultimately on the general health: on the physical health, in the first place (defect of growth of the jaws, the solid mass, the mouth breathing, articular disorders postural) and also on the mental and psychological health (Impact of breastfeeding on the cognitive development of the child, dependent dose effect: santeallaitementmternel.com). WHO states that "mental health is a state of complete physical, mental and social well-being and not just the absence of disease".

The invention aims to reproduce all the functions performed by breastfeeding, both physically and psychologically. In view of the devices currently marketed, there is clearly a need for a pacifier that reproduces the muscular work produced by the child during breastfeeding, especially the lips, cheeks, and more generally the facial muscles, tongue and masticatory muscles, to respect the oral anatomy of the child and thereby avoid the occurrence of maxillofacial development disorders and disorders of relationships between the dental arches and improve the general health of individuals .

In particular, the invention seeks to reproduce the natural peristaltic movement of the tongue. The natural peristaltic movement of the tongue creates a wave at the center of the gutter formed by the child's tongue, bent around the nipple when it is in a position to suckle.

Psychologically, the Applicant seeks to meet the basic need of physical contact of the child by reducing the distance between the mother and the child often increased during artificial feeding, which preserves olfactory stimulation, hearing , visual and natural dermal breastfeeding.

Some studies have shown that prolonged contact time between the mother and the child significantly enhances the bond of attachment between the mother and the child and the cognitive development of the child. Observation of the mother and the child during breastfeeding, maternal or artificial, shows that the postural adjustment of some mothers leads to clumsiness and discomfort, for the mother as for the child. The present invention therefore also seeks to optimize postural adjustment mother-child.

Short description

Thus, the invention relates to a pacifier intended to be placed in the mouth of a child, characterized in that it comprises at least three integral parts, which are a stud comprising at its end at least one perforation for the passage a liquid, an areola, an isthmus joining the nipple to the areola, and optionally a skirt, nipple in which: the nipple comprises an upper part or palatal part and a lower part or lingual part which are asymmetrical; the palatal portion of the nipple comprises means for ensuring the correct positioning of the nipple against the child's palate; the lingual portion of the nipple is of generally convex shape in the center with two lateral concavities allowing the gutter of the tongue of the child to be in its natural position in the gutter, in contact with the pacifier; these technical characteristics thus ensure the natural positioning of the child's tongue and the natural peristaltic movement,

- the isthmus junction between the nipple and the areola, this junction being narrowed for a good placement of the upper and lower jaws, the isthmus further comprising means for ensuring the controlled expulsion and the flow of milk out the pacifier under the muscular action of the child on the pacifier;

- The areola has a very slightly concave shape and has a wide neck so as to ensure a child-pacifier contact of the chin to the nose.

Advantageously, the pacifier according to the invention comprises means making it possible to ensure the correct positioning of the nipple against the child's palate, said means being surface states contributing to the function of the feeding, namely salient elements and / or or rough on the palatal part.

According to a preferred embodiment of the invention, the salient and / or rough elements on the palatal part and the smooth surface state of the lingual part favor the correct function of the suckling.

According to a first embodiment, the means for ensuring the correct positioning of the nipple against the child's palate are protruding elements molded on the surface of the upper part bringing to the surface of the upper part a roughness which holds it against the child's palace. According to another embodiment, the palatal portion of the nipple has a thickness of 1 to 5 mm and the lingual portion of the nipple has a thickness of 0.1 to 2 mm and has a smooth surface to avoid any irritation of the tongue . In another embodiment, the pacifier is molded in one piece. The molding can be done by injection-molding or molding-compression.

According to the invention, the nipple is provided at its end or on its most extreme upper surface with at least three perforations, for example 3, 4, 5, 6, 7, 8 or 9 perforations. According to a preferred embodiment of the invention, the stud is provided with 3 to 7 perforations, preferably 5 perforations. Said perforations preferably have a diameter of 0.3 to 0.6 mm, preferably about 0.4 mm.

Advantageously, the means present in the isthmus allow (1) to ensure the flow of milk from the areola to the nipple under the action of the child's masticatory muscles which compress the valve, (2) to facilitate the expulsion of the milk outside the pacifier through the perforations mentioned above, under the effect of the peristaltic movement of the tongue, limiting the reflux of milk to the areola. These means are a valve, a bevel opening, a flap, a diaphragm or a biconcave lens, preferably a valve consisting of a vertical slot of 3 to 8 mm, preferably 4 to 6 mm, more preferably 5 mm. The flow of the milk is favored by a minimum of vertical pressure of the mandible on said means, therefore by the minimum muscular effort of propulsion necessary for the growth of the mandible. The effort of the masticatory muscles (masseter, pterygoid and temporal) also makes it possible to pull the larynx in the upper position and thus to ensure the seal between the oral cavity and the upper airways, thus limiting the phenomena of false-road and otitis. According to a preferred embodiment of the invention, these means allow a minimum flow of liquid in the absence of pressure through the valve. However, because of the fineness of the perforations and the size and shape of the valve, the pacifier does not allow any unwanted flow of liquid under the simple effect of gravity. In particular, said means make it possible to limit, or even to completely avoid, the reflux of milk in the reservoir (the valve being closed because not compressed by the mandible at this time of feeding).

According to a preferred embodiment, the nipple has a length, from the end of the nipple to the opposite end of the nipple, between 2.5 and 5.5 centimeters, preferably between 3 and 5 centimeters, very preferably 4 to 4.5 centimeters.

Advantageously, the teat according to the invention is made of thermoplastic elastomer, latex or silicone, preferably silicone having a hardness Shore 30 to 45, preferably 35 to 40, more preferably about 35 degrees Shore.

Advantageously, the pacifier according to the invention has a thickness of about 1 mm, with the exception of the palatal and lingual zones of the nipple as explained above, and a texture close to that of the dermis. Advantageously, the texture of the pacifier is provided by its surface condition, which is rough at the palatal zone and smooth at the lingual level. Advantageously, the surface condition of the nipple results from work on the surface condition of the mold.

The pacifier according to the invention may comprise a skirt for fixing to a reservoir; in this embodiment, the teat is preferably food.

According to another embodiment, the pacifier according to the invention is non-food (lollipop); in this embodiment, the pacifier is preferably provided with a screen avoiding the absorption of air by the child, and is preferably attached to a gripping means.

The invention also relates to a feeding bottle comprising a teat according to the invention, a reservoir and a teat retention ring on the reservoir, said reservoir having an angulation of between 60 to 110 °, preferably about 90 °. According to a preferred embodiment of the invention, the reservoir has at its end opposite the nipple an opening, preferably closed by a silicone stopper that can be removed during lactation to ensure the replacement of the liquid consumed by air. Said stopper preferably has a Y shape. The capacity of the reservoir is preferably from 200 to 250 ml. The invention also relates to a nursing system comprising a bottle according to the invention comprising a reservoir, and a reservoir holder comprising a strap, wherein said reservoir comprises means for fixing the reservoir door to the reservoir. The combination of the angulation of the reservoir and the reservoir-holder makes it possible to preserve the mother-child natural position; with skin-to-skin contact and the preservation of sensory stimuli. detailed description

Figure 8 shows a front view of the pacifier, representing a means for example a line, locating that verifies the proper placement of the asymmetrical pacifier in the child's mouth.

Figure 9 shows a perspective view of the bottle according to the invention.

Figure 1 shows a side view of the nipple 1 comprising four integral parts, an end nipple 2, an areola 4, an isthmus 3 joining the nipple to the areola, the palatal 6 and lingual 7 of the nipple 2, the perforations 8 and optionally a fastening skirt 5. In particular, Figure 1 shows a side view of the stud 2 which illustrates the asymmetry of the stud 2, and in particular the curved shape of the palatal portion 6. FIG. 2 represents a side view of the nipple 1 comprising an areola 4, an isthmus 3 joining the nipple 2 to the areola 4, the palatal part 6 seen from the front, and the perforations 8.

The nipple 2 (shown in Figure 7 as being endobuccal) has a morphology adapted to the anatomy of the child. It has an elliptical or oval shape. The reduced size, as well as the elliptical shape of the pacifier according to the invention compared to conventional teats is intended not to cause deformities of the maxillary and palate.

The nipple 2 is asymmetrical. The upper or palatal 6 of the nipple 2 has a shape close to a half-bubble, which is a shape adapted to the child's palate and allows the stimulation of the zone which is at the origin of a suction reflex . Advantageously, the half-bubble has a radius of 4 to 8 mm, preferably about 6 mm. On the surface of this half-bubble are means for ensuring the proper positioning of the nipple 2 against the child's palate: these means are roughness or salient elements (not shown) molded with the nipple; these roughness or salient elements as well as the thickness of the material (shown in FIG. 4) make it possible to facilitate the stabilization of the teat by the palatal scrubs and thus to retain the lug 2 against the child's palate. According to a preferred embodiment of the invention, the palatal portion 6 of the stud 2 is of a thickness of 1 to 5 mm.

The lower or lingual portion 7 of the nipple 2 has a very slightly convex shape in the center with two lateral concavities 12, shown in Figure 3, which allow a correct placement of the tongue (which forms a gutter during feeding). Advantageously, the palatal portion 6 of the nipple 2 is thicker than the lingual portion of the nipple 2, which is 0.1 to 2 mm thick, preferably 0.5 to 1 mm thick. At the lingual part of the nipple, the thickness of the material is thus low (see Figure 4) to have great flexibility and allow the peristaltic movement of the tongue that causes the milk to come out of the nipple. The surface of this area is perfectly smooth for easy sliding of the tongue. This particular conformation of the nipple 2 furthermore makes it possible to prevent the piston movement of the tongue against the palate, leading to a deepening of the palate to the detriment of the nasal cavities and to reducing the significant suction force limiting the transverse growth of the maxillae with the current pacifiers.

To avoid palatal deformity, the nipple 2 is wider than it is high except at the level of the "palatal bubble". In any case, the upper part or palatal part 6 and the lower or lingual face 7 of the nipple 2 are different from each other.

Preferably, the stud 2 is provided, at its end or on its most extreme upper surface, with at least three perforations, preferably 3 to 7 perforations, even more preferably 5 perforations 8, intended for the passage of a liquid, whose diameter is smaller than the perforation of traditional bottles, preferably a diameter of 0.3 to 0.6 mm, preferably about 0.4 mm, which makes it possible to limit an excessive flow of liquid related to weightlessness and to obtain a flow natural liquid, watering type.

The isthmus 3 (shown in Figure 7 as being endobuccal) is the part that joins between the nipple 2 and the areola 4, this junction being narrowed for a good placement of the upper and lower jaws. The isthmus 3 further comprises means 13 (an embodiment of which is shown in FIG. 5) of ensuring the controlled expulsion of the milk under the muscular action of the child on the pacifier. Preferably, the means 13 to ensure the flow of milk under the muscular action of the child on the pacifier are: a valve, a bevel opening, a flap that opens to let the liquid, for example milk or water, when the isthmus is compressed, a diaphragm, a biconcave lens or any other suitable means. This means 13 may be molded together with the teat, or independently. According to a preferred embodiment of the invention, this means 13 is a valve integrated in this zone of the isthmus. This valve makes it possible to regulate the flow of milk in the nipple, but is, according to a preferred embodiment of the invention, never completely closed and the opening of the valve is increased only under the muscular action of the new -need (stimulation of the pterygoid muscles lateral, temporal, and masseter). Preferably, the valve consists of a vertical slot of 3 to 8 mm, preferably of about 4 to 6 mm, more preferably 5 mm which under the effect of pressure forms a square section conduit (see FIG. 5). The flow of the milk is favored by a minimum of vertical pressure of the mandible on the valve, therefore by the minimal muscular effort of propulsion necessary for the growth of the mandible. The effort of the masticatory muscles (masseter, pterygoid and temporal) also makes it possible to pull the larynx in the upper position and thus to ensure the seal between the oral cavity and the upper airways, thus limiting the phenomena of false-road and otitis.

The areola 4 (shown in Figure 7 as exobuccal) reproduces the shape of the breast when the head of the child is supported. She is very slightly shaped concave, the child's lips coming to bear on the half of the areola opposed to the nipple. The areola is sufficiently large in diameter, or has a sufficiently wide neck, to ensure a child-teat contact of the chin to the nose. Advantageously, the neck of the areola has a diameter of 40 to 50 mm. Advantageously, in its longitudinal section, the areola has a rounder shape, less triangular (closer to the shape of the breast) than conventional teats ensuring child teat contact of the chin to the nose. In its longitudinal section, the round shape of the areola ensures a child-teat contact of the chin to the nose. The contact areas of the child with the pacifier of the invention are shown in FIG. 7. The presence of the valve, the fineness of the material on the lingual surface, the fineness of the perforations 8 for the evacuation of the milk, as well as the shape of the areola participate in a physiological work of the orofacial musculature and in the correction of the natural distosition of the mandible of the newborn. Advantageously, the color of the pacifier reproduces the color of the aerole and the maternal nipple, namely a brown or brown color. Preferably, the pacifier has a surface state close to that of the maternal breast.

As shown in FIG. 1, the teat according to the invention is modeled according to 6 zones:

ZONE 1: Zone allowing the correct anteroposterior placement of the child's face with contact of the nose to the chin: concave shape; the zone 1 of the nipple has the function of providing anteroposterior elasticity of 3 to 7 mm, preferably of 4 to 6 mm, more preferably of approximately 5 mm, allowing a displacement of the nipple from front to back in the child's mouth. This function is made possible because the zone 1 has a bellows shape of one or more folds (not shown) allowing the deformation under the action of the child, and the return to the rest position.

ZONE 2: Zone allowing the placement of the lips of the newborn and a good crimping of these around the pacifier (work of the musculature jugale and labial): convex form.

ZONE 3: Upper and lower jaw placement area with upper and lower concavities for precise nipple placement in the child's mouth. In the inner part of zone 3, is the valve whose opening will be increased under pressure of the mandible, thus allowing the work of the musculature related to the temporomandibular joint (masseter, pterygoid and temporal muscles). This muscular action is essential for the correction of natural neonatal retromandibulia and allows a complete closure of the bucco-laryngeal isthmus so as to avoid regurgitation of milk in the upper aero-digestive tract of the child, as well as otitis resulting.

ZONE 4: Zone 4 includes an upper part and a lower part.

The upper part is a curved area allowing the perfect teat of the pacifier at the level of the palate. The lower part is an area receiving the tip of the tongue just above and behind the mandible. In a superior view, the zone 4 forms a U favoring a normal development of the dental arches.

ZONE 5: Zone 5 comprises an upper part and a lower part.

The upper part is a zone of contact with the palatal ruga, the thickness of which is greater and the texture is more irregular for a maximum maintenance of the nipple (corresponding palatal mucosa thicker and more resistant). The lower part of zone 5 is a lingual work area with a shape adapted to the lingual form, and minimal thickness with very smooth surface condition to allow lingual peristaltic movements.

ZONE 6: Zone 6 is the end portion of the nipple, the end of which is at the level of the hard palate / soft palate junction; this zone 6 comprises at least three perforations, preferably from 3 to 7 perforations, even more preferably 5 perforations 8, for a natural flow of milk.

Figure 6 shows a sectional view of the nipple according to the invention, on which measurement marks have been marked. Thus, at the marks A, B, C, D of Figure 6, corresponding to the zone 1 shown in Figure 1, the teat of the invention has a height between 45 and 55 mm.

Preferably, at reference A, the teat has a height of 40-50 mm, preferably 42 to 45 mm, very preferably approximately 43.5 mm.

Preferably, at reference B, the teat has a height of 40-50 mm, preferably 42 to 48 mm, very preferably approximately 45 mm.

Preferably, at reference C, the teat has a height of 45-55 mm, preferably 50 to 54 mm, very preferably approximately 53.5 mm.

Preferably, at reference D, the teat has a height of 40-50 mm, preferably 42 to 48 mm, very preferably approximately 45 mm. Preferably, at the E mark, the teat has a height of 40-50 mm, preferably 42 to 45 mm, very preferably approximately 43.5 mm.

Preferably, at the F mark, the teat has a height of 35-45 mm, preferably 36 to 40 mm, very preferably approximately 38.5 mm.

Preferably, at the mark G, the teat has a height of 15-55 mm, preferably 18 to 23 mm, very preferably about 21.5 mm.

At the level of the isthmus 3, H marks to J, the teat has a height of 5 to 10 mm, preferably 6 to 9 mm.

Preferably, at the H mark, the teat has a height of 5-10 mm, preferably 6 to 8 mm, very preferably about 7 mm.

Preferably, at reference I, the teat has a height of 5-10 mm, preferably 6 to 7 mm, very preferably approximately 6.5 mm.

Preferably, at the mark J, the teat has a height of 5-10 mm, preferably 6 to 9 mm, very preferably approximately 7.5 mm.

At the level of the palatal half-bubble of the nipple 2 (K mark), the nipple has a height of 8-12 mm, preferably 9 to 11 mm, very preferably approximately 10.5 mm.

According to a preferred embodiment of the invention, the nursing system according to the invention is designed so that the reservoir 9 rests on the upper part of the bust of the woman in the central or lateral position to find the "face to face Natural mother - child. According to a preferred embodiment of the invention, the reservoir 9 has a traditional round section. Advantageously, the reservoir 9 comprises means of being attached to a strap that can be passed around the neck of the woman to form the artificial feeding system according to the invention. In this system, the reservoir 9 can advantageously rotate left or right in order to facilitate the placement of the child.

Advantageously, the bottle (an embodiment of which is shown in FIG. 9) comprises a reservoir 9 capable of having an angulation 11, a ring 10 and a teat 1, said ring 10 or said teat 1 comprising means, for example a line, locating that verifies the proper placement of the asymmetrical pacifier 1 in the mouth of the child: the locating means must be placed next to the columella of the child. According to a preferred embodiment, shown in Figure 8, the mark is placed on the pacifier 1. According to another embodiment, not shown, the mark is placed on the ring 10.

Unlike traditional bottles, both hands of the mother can participate in the maintenance of the child, whose head is against or between the breasts of his mother. The distance between the child and his mother is thus reduced. The child thus benefits from olfactory, visual, auditory, tactile and thermal stimulation.

Thanks to the angulation 11 of the reservoir, the child is breastfed in a more vertical position compared to traditional systems, which limits the rise of milk in the upper airways and therefore ear infections. According to a preferred embodiment of the invention, the main part of the reservoir 9 has an angulation 11 of 60 to 110 °, preferably 70 to 100 °, more preferably close to 90 ° with the zone of attachment of the nipple 1 allowing a good placement of the child for breastfeeding. The reservoir 9 has at its end opposite the nipple 1 an opening receiving a silicone plug, preferably Y-shaped, which will be removed during lactation to ensure the replacement of the liquid consumed, for example milk or water by air, thus making it possible to improve the preservation of the qualities of the liquid, to ensure its flow and to prevent too much work of the juvenile musculature limiting the transverse growth of the maxillary and the mandible.

According to a preferred embodiment of the invention, the reservoir 9 is made of glass.

According to a particular embodiment of the invention, the feeding bottle further comprises a sieve of the form of a disc placed at the level of the reservoir junction 9-teat 1 before the skirt 5 of the nipple 1. This sieve has as its function to prevent the passage of lumps in the nipple 1, especially if, for example, substitute milk is used.

The device according to the invention, which is more respectful of the development of children than the devices of the prior art, furthermore has the advantage of reinforcing the mother-child relationship by stimulating the different senses of the child, by approaching as far as possible breastfeeding, which brings short-, medium- and long-term medical interest to the child's growth.
