Pacifier

Abstract

The present invention relates to a pacifier, by means of which it is possible to detect whether a user has generated a negative pressure in the oral cavity necessary to maintain the tongue in contact with the maxilla, thereby stimulating the expansion of the maxilla to guide the normal growth of associated structures in the face and the mouth-nose respiratory system. Further, the pacifier serves as a guide for initiating the eruption of deciduous teeth exposed from the gums, where the pacifier is thus adapted to companion with users in different growth stages.

Description

Technical Field

[0001] The present invention relates to a type of pacifier for use by infants, wherein the pacifier has a device that allows for the visual display of a vacuum pressure in the infant's mouth (particularly in the espacioDonders) and also maintains said vacuum pressure to indicate and promote normal function of the infant's nose and mouth. Background Technology

[0002] Pacifiers have been used for centuries as a device to satisfy a baby's sucking urges. Therefore, pacifiers are generally considered a common item used by babies.

[0003] Therefore, devices that include the ability to perform stimulating actions on an infant (e.g., reproduce musical sounds or the voice of a parent, or supply substances or medications, etc.) have already been included as complementary uses to pacifiers.

[0004] On the other hand, pacifiers are also related to the development of an infant's sucking ability, which has a special influence on the development of the entire musculoskeletal structure of the face and the associated structures in the oronasal respiratory complex.

[0005] Based on this fact, a review of the scientific literature indicates that the relationship between oral cavity development and nasal breathing efficiency is extensive. Some studies have even suggested that nasal breathing difficulties due to palatal collapse may be a cause of sudden infant death syndrome (SIDS).

[0006] Based on the above, and considering that pacifiers are a commonly used component for infants and are part of their development, it has been proposed that a device be incorporated into pacifiers to allow parents and / or healthcare professionals to verify the normal function of an infant's nose and mouth, whether awake or, more importantly, asleep.

[0007] Given that the normal function of an infant's nose and mouth is to generate and maintain negative pressure in the mouth (in the Dondes space) to keep the tongue in contact with the maxilla, thereby stimulating the expansion of the maxilla to guide the normal growth of the face and the associated structures in the oro-nasal respiratory complex, there is clearly a need to provide a pacifier that promotes the normal function of an infant's nose and mouth. Summary of the Invention

[0008] In response to the identified need, according to a first aspect, the present invention provides a pacifier as disclosed in claim 1, wherein the pacifier can detect whether the user generates negative pressure in the oral cavity required to maintain contact between the tongue and the maxilla, thereby stimulating the expansion of the maxilla to guide the normal growth of associated structures in the facial and oronasal respiratory complex.

[0009] As described above, the proposed pacifier includes a base plate, a cup-shaped component that can be airtightly connected to the base plate, and a nipple head that can be connected to the base plate and / or the cup-shaped component.

[0010] As is well known, the substrate is arranged to act as a stop against the lips and to prevent the user from swallowing the nipple.

[0011] On the other hand, in addition to providing the user with the known function of a sucking element, the nipple also features an orthodontic design that allows a portion of the nipple to be positioned between the tongue and palate, specifically in the Donders' intercostal space, to record negative pressure within this space. Appropriate pressure is crucial for maintaining ideal positioning of tissues within the oral cavity, nose, and pharynx. The recording of appropriate negative pressure in the Donders' intercostal space thus indicates proper sucking by the user, which in turn indicates normal function of the user's nose and oral cavity.

[0012] Based on the above, the nipple is configured to establish fluid communication between the Donders gap in the oral cavity and the cup-shaped component, so that the vacuum pressure in the Donders gap is transmitted to the cup-shaped component.

[0013] In this sense, the cup-shaped piece has an indicator for indicating the pressure transmitted toward it. In a preferred embodiment, this indicator takes the form of a retractable region arranged within the cup-shaped piece, which retracts under the influence of the aforementioned negative pressure, thus visually demonstrating that the negative pressure in the Dondes gap is sufficient and that sucking is appropriate. By transmitting vacuum pressure to the cup-shaped piece, it helps maintain the vacuum pressure, and therefore also helps to keep the tongue in contact with the palate (i.e., the maxilla).

[0014] As described above, the retractable area of ​​the cup-shaped component can be a membrane that conveniently retracts to provide visual feedback to anyone, confirming normal nasal and oral function for the user (especially an infant) using the pacifier of the present invention. The retraction of the retractable area indicates appropriate, relaxed nasal breathing to the user.

[0015] Alternatively, in other alternative embodiments, the indicator for indicating the pressure transmitted to the cup-shaped member may be an LED light, or it may capture the vacuum pressure and transmit the detection to an external device, such as a computer, smartphone, etc., for its subsequent processing.

[0016] Regarding the latter, the pacifier includes an electronic unit connected to a cup-shaped component, wherein the electronic unit is configured to receive an indicator signal indicating the retraction of a retractable region of the cup-shaped component and / or the presence of a vacuum in the Dondes gap, wherein an indicator device or indicator apparatus is connected to the electronic unit to indicate the retraction of the retractable region and / or the presence of a vacuum in the Dondes gap captured by the electronic unit.

[0017] In an alternative embodiment, the electronic unit is arranged on a substrate and includes a sensor configured to detect the retraction of the retractable region and / or the presence of a vacuum in the Donders gap. Preferably, the sensor is a switch activated when the retractable region retracts, such that the activation of the sensor activates an indicator device, as mentioned, which may be a selectively on or off LED light or audible signal, etc. Even more preferably, the indicator device is an LED light arranged in the electronic unit.

[0018] In another embodiment, the pacifier includes a housing designed for accommodating an electronic unit and a flexible tube designed to fluidly connect a cup-shaped component to the housing. The electronic unit, in addition to sensors for detecting the retraction and / or vacuum pressure of the retractable area, also includes processing means for processing the detected data, storage means for storing the data, and communication means for transmitting the data for further processing or analysis, or for downloading the data in an editable format. In a preferred embodiment, the housing takes the form of a clip designed to attach to the user's clothing.

[0019] On the other hand, the nipple includes a proximal end and a distal end, the proximal end being connected to the substrate, and the distal end being designed to be positioned within the Donders gap in the oral cavity. Preferably, the nipple is hollow and includes at least one hole located at the distal end, such that said at least one hole transmits vacuum pressure from the Donders gap to the cup-shaped member, thereby causing the retractable region to retract. It is important to note that the design of the position of the hole (or holes) on the nipple is crucial for measurements to be taken solely and entirely within the Donders gap, unaffected by any other factors, such as positive pressure from the tongue against the palate.

[0020] In this respect, it should be noted that the substrate includes a housing configured for attaching the proximal end of the nipple, and a connection port intended for attaching the cup-shaped component, wherein the housing and the connection port are arranged on the substrate, thereby enabling fluid communication between the nipple and the cup-shaped component. Furthermore, both the housing and the connection port are configured to seal the nipple and the cup-shaped component to the substrate, such that vacuum pressure is fully transmitted to the cup-shaped component to visually indicate its presence.

[0021] In addition to the above, pacifiers also include an intraoral shield, which is configured to be inserted between the outside of the teeth and the inside of the lips and cheeks. This intraoral shield is designed to act as a guide for the emergence of primary teeth from the gums without causing malocclusion, thus allowing the newborn's toothless mouth to transition from a liquid diet (breast milk / formula) to a solid diet, thereby supporting weaning.

[0022] Like the rest of the pacifier components, the screen is made of hypoallergenic material and can be adjusted to fit each user’s oral cavity morphology, which is defined as the space between the teeth and the lips and cheeks.

[0023] In a second embodiment, the present invention provides a pacifier comprising a base plate and a cup-shaped member having a retractable region that is hermetically attachable to the base plate, as in a previous embodiment. Compared to the previous embodiment, the pacifier includes an intraoral screen attachable to the base plate and / or the cup-shaped member, wherein the intraoral screen is in fluid communication with the cup-shaped member and is configured to be inserted between the exterior of the teeth and the interior of the lips and cheeks, serving as a guide for the eruption of primary teeth beginning to emerge from the gums, wherein vacuum pressure from the oral cavity is transmitted to the cup-shaped member, causing the retractable region to retract.

[0024] In this second embodiment, due to the use of, for example, a pacifier as in the first embodiment, a suitable vacuum is created in the Donders gap by the user. Thus, sucking is appropriate, and the pacifier is removed after normal development and after promoting tissue and bone growth and the eruption of deciduous teeth. Thus, under the influence of the vacuum pressure in the oral cavity, the retractable area of ​​the cup-shaped member will contract, visibly demonstrating the appropriate sucking. By transmitting the vacuum pressure to the cup-shaped member, it helps maintain the vacuum pressure, and therefore it also helps to keep the tongue in contact with the palate (i.e., the maxilla).

[0025] The intraoral shield includes a tube projecting from it, having an open end to define a channel through which fluid communication with a cup-shaped member is established. In this sense, when the intraoral shield is located in the oral cavity and occupies the Frankel space, one open end is oriented toward the interior of the oral cavity, while the other end is oriented toward the cup-shaped member, which is hermetically connected at said end.

[0026] Alternatively, in this second embodiment, a nipple that can be coupled to an intraoral screen can be provided, the nipple being configured to establish fluid communication between the Donders gap in the oral cavity and the cup-shaped member, such that vacuum pressure in the Donders gap causes the retractable area of ​​the cup-shaped member to retract.

[0027] This implementation is possible because the user may need a nipple at some point during the weaning process.

[0028] Therefore, the nipple includes a proximal end and a distal end, with the proximal end connected to the substrate and the distal end designed to be positioned in the Donders gap of the oral cavity.

[0029] Preferably, the nipple is hollow and includes at least one hole disposed at the distal end, such that the at least one hole transmits vacuum pressure from the Donders gap to the cup-shaped member, thereby causing the retractable area to retract. Attached Figure Description

[0040] In the following detailed description, numerous specific details are illustrated with examples to provide a thorough understanding of the teachings. However, it will be apparent to those skilled in the art that these teachings can be implemented without these details.

[0041] like Figures 1 to 4As shown, in a preferred embodiment of the first embodiment, the present invention discloses a pacifier 1 intended for use by an infant, the pacifier 1 comprising a substrate 2, a cup-shaped member 4, and a nipple 3.

[0042] Within the scope of this detailed description, and considering that its use is primarily intended for infants between 0 and 18 months of age, the terms “user,” “infant,” or “toddler” will be used interchangeably to refer to the user to whom the pacifier 1 is intended.

[0043] The substrate 2 includes a connection port 2A intended for connecting the cup-shaped member 4, wherein in this embodiment, the connection is performed in a sealing manner by a snap-fit ​​connection, allowing the cup-shaped member 4 to be released from the connection port 2A, such as... Figure 7 As shown.

[0044] The substrate 2 also includes a housing 2B in the form of a through hole designed for a sealing connection of the nipple 3, wherein the housing 2B coincides with the connection port 2A to enable fluid communication between the nipple 3 and the cup-shaped member 4.

[0045] Similarly, the nipple 3 is hollow and orthodontically designed, providing not only a sucking function but also positioning it between the infant's tongue and palate. It includes a proximal end 3B, through which the nipple 3 is hermetically connected to the substrate 2, particularly the housing 2B. The proximal end 3B has a protrusion 3D that prevents accidental disconnection of the nipple 3 once it is connected to the housing 2B. The nipple 3 also includes a distal end 3A, positioned between the infant's tongue and palate, particularly in the Donders gap of the oral cavity. Multiple holes 3C are arranged at the distal end 3A, such that, considering the hollow configuration of the nipple 3, the holes 3C transmit vacuum pressure from the Donders gap to the cup-shaped member 4, causing the retractable region 4A of the cup-shaped member 4 to retract.

[0046] As can be seen, in this preferred embodiment, the cup-shaped member 4 has a tubular cylindrical shape, with its closed end serving as a cap, wherein a retractable region 4A is arranged within the cap. The stiffness of the cap will be selected so that its retractable region 4A can easily retract under the influence of vacuum pressure. Preferably, the retractable region 4A is the entire cap and is composed of a flexible membrane, which is prepared to retract under the influence of vacuum pressure and return to its original state when the vacuum pressure is released. Therefore, the material for manufacturing the cup-shaped member 4 (especially the retractable region 4A) will be selected so that when the retractable region 4A retracts, the retraction can be visually observed by a person (e.g., a medical professional or the parents of an infant).

[0047] Therefore, when an infant uses the pacifier 1, the distal end 3A of the nipple 3 is placed in the Donders gap, capturing its vacuum and revealing the vacuum through the retraction of the retractable region 4A of the cup-shaped member 4.

[0048] like Figure 8 As shown, in a preferred embodiment of this first embodiment, the pacifier 1 includes a sleeve 2C protruding from a substrate 2, wherein a connection port 2A is arranged opposite to the substrate 2, and wherein a housing 2B is at least partially disposed within the sleeve 2C. An electronic unit 6 is configured to be disposed within the sleeve 2C, wherein the electronic unit 6 is configured to be connected to a cup-shaped member 4 such that it receives the retraction of a retractable region 4A of the cup-shaped member 4. In the illustrated embodiment, the electronic unit 6 includes a sensor 7 in the form of a switch, which is actuated by the retraction of the retractable region 4A in the presence of vacuum pressure in the oral cavity. In addition to indicating the presence of a vacuum through the retractable region 4A, the electronic unit 6 also includes an LED (not shown) connected to the sensor 7 (i.e., connected to the switch), and an accumulator 8 in the form of a battery to power and energize the LED when the switch is activated. In this way, the presence of a vacuum in the Donders gap is indicated to the user by the retraction of the cup-shaped member 4 and also by the illumination of the LED.

[0049] exist Figure 9 In another illustrated alternative embodiment, the electronic unit 6 is arranged in a housing 9, which is fluidly connected to the cup-shaped member 4 via a flexible tube 9A. In addition to the sensor 7 for detecting the retraction and / or vacuum pressure of the retractable region, the electronic unit 6 also has a processing device (not illustrated) for processing detection data from the sensor 7, a storage device (not illustrated) for storing the data, and a communication device (not illustrated) for transmitting the data for further processing or analysis, or for downloading the data in an editable format. Figure 9 As shown, preferably, the housing 9 takes the form of a clip designed to attach to the user's clothing. In this sense, the clip has an opening 9B for attaching to the clothing.

[0050] In addition to the above, membrane 8A (preferably Goretex® type membrane 8A) is arranged inside sleeve 2C and configured to prevent fluid from the user's mouth from contacting control unit 6.

[0051] Similarly, alternatively, the connection between the cup-shaped member 4 and the substrate 2 via the connection port 2A can be threaded.

[0052] In a variation of this first embodiment, such as Figure 3 and Figure 4 As shown, the pacifier 1 includes an intraoral screen 5 which is connectable to the nipple head 3, particularly in the region near the proximal end 3A. The intraoral screen 5 is intended to be inserted between the outside of the teeth in the so-called Frankel's gap and the inside of the lips and cheeks, and is configured to serve as a guide for the eruption of deciduous teeth that begin to emerge from the gums.

[0053] The intraoral shield 5 is made of a soft-touch polymer material (such as soft silicone) that can be cut and adapted to the size of an infant's mouth. As described above, the intraoral shield is designed to occupy the Frankel space, which serves as the labial vestibule. This space is the area between the outer surface of the teeth (or the intended location of the teeth upon entry) and the interior of the lips and cheeks. The implementation of the intraoral shield 5 in the pacifier 1 allows for proper tooth eruption and development without resulting in malocclusion.

[0054] The inner screen 5 can be optionally connected to the nipple 3, or it can be a single piece with the nipple 3.

[0055] On the other hand, Figure 5 and Figure 6 The illustration shows a second embodiment of the invention, illustrating a pacifier 10 for a more advanced developmental stage, intended for weaning and thus requiring the removal of the nipple. In this manner, the pacifier 10 in this second embodiment includes a base plate 20, a cup-shaped member 40 hermetically attachable to the base plate 20, and an intraoral shield 50 attachable to the base plate 20, the cup-shaped member 40 including a retractable region 40A, wherein the intraoral shield 50 is in fluid communication with the cup-shaped member 40 via a channel 52 connecting the two elements. The intraoral shield 50 is configured to be inserted between the exterior of the teeth and the interior of the lips and cheeks, occupying the Frankel space, and serving as a guide for the eruption of primary teeth beginning to emerge from the gums and preventing malocclusion, such that vacuum pressure from the oral cavity is transmitted to the cup-shaped member 40, causing the retractable region 40A to retract.

[0056] The vacuum indicated by the retraction of the retractable region 40A of the cup-shaped member 40 is generated by the infant's sucking in the mouth, wherein the maintenance of this vacuum is an indication of the normal functioning of the airway and the normal development of all associated morphological structures (i.e., the tissues in the mouth, nose and pharynx, and the growth of the mandible).

[0057] like Figure 7 As shown, the intraoral screen 50 includes a tube 51 protruding therefrom, the tube 51 having an open end to define a channel 52, in Figure 5 and Figure 6 It was observed that fluid communication with the cup-shaped component 40 was established through this channel.

[0058] It is important to note that the substrate 20 and cup-shaped member 40 of this second embodiment have the same shape and function as described for their corresponding analogues in the first embodiment. Therefore, the description of these elements in the first embodiment of the invention is extended to these elements.

[0059] Optionally, in the pacifier 10, a nipple head 30 that can be connected to the intraoral screen 50 may be incorporated. The nipple head 30 is configured to establish fluid communication between the Donders gap in the oral cavity and the cup-shaped member 40, such that the vacuum pressure in the Donders gap will cause the retractable area 40A of the cup-shaped member 40 to retract, thereby making the vacuum visually apparent.

[0060] The nipple 30 includes a proximal end 30B and a distal end 30A. The nipple 30 is connected to the intraoral screen 50 via the proximal end 30B, particularly at the entrance of the channel 52, and the distal end 30A is designed to be positioned in the Dondes gap.

[0061] Furthermore, the nipple 30 is hollow and includes a plurality of holes 30C arranged at the distal end 30A, such that the holes 30C transmit vacuum pressure from the Donders gap to the cup-shaped member 40 through the nipple 30, thereby causing the retractable region 40A to retract.

[0062] Similarly, in this second embodiment, similar to the first embodiment, such as Figure 8 As observed, the pacifier 10 includes a sleeve 20C protruding from a base plate 20, wherein a connection port 20A is arranged opposite to the base plate 20, and wherein a housing 20B is at least partially disposed inside the sleeve 20C. An electronic unit 60 is configured to be disposed inside the sleeve 20C, wherein the electronic unit 60 is configured to be connected to a cup-shaped member 40 such that it receives retraction of a retractable region 40A of the cup-shaped member 40. In the illustrated embodiment, the electronic unit 60 includes a sensor 70 in the form of a switch, which is actuated by the retraction of the retractable region 40A in the presence of vacuum pressure in the oral cavity. In addition to indicating the presence of vacuum through the retractable region 40A, the electronic unit 60 also includes an LED (not shown) connected to the sensor 70 (i.e., connected to the switch), and an accumulator 80 in the form of a battery to power and energize the LED when it is activated by the sensor 70. In this way, the user is shown the presence of a vacuum in the Dondes gap by the retraction of the cup-shaped part 4 and also by the illumination of the LED.

[0063] In another alternative embodiment of the second embodiment, such as Figure 9 As illustrated, the electronic unit 60 is arranged in a housing 90, which is fluidly connected to the cup-shaped member 40 via a flexible tube 90A. In addition to a sensor 70 for detecting the retraction and / or vacuum pressure of the retractable region 40A, the electronic unit 60 also includes a processing device (not illustrated) for processing detection data from the sensor 70, a storage device (not illustrated) for storing the data, and a communication device (not illustrated) for transmitting the data for further processing or analysis, or for downloading the data in an editable format. Figure 9As shown, preferably, the housing 90 takes the form of a clip designed to attach to the user's clothing. In this sense, the clip has an opening 90B for attaching to the clothing.

[0064] In addition to the above, the membrane 80A (preferably a Goretex® type membrane 80A) is arranged inside the sleeve 20C and is configured to prevent fluid from the user's mouth from contacting the control unit 60.

[0065] Similarly, alternatively, the connection between the cup-shaped member 40 and the substrate 20 via the connection port 20A can be threaded.
