Description

[Technical Field]

[0001] The present invention relates to a pacifier and a pacifier system. [Background technology]

[0002] Pacifiers have been used for a long time, and in recent years, research has revealed the following effects: When an infant or young child is nursing, if a nipple or other device is placed in the "sucking cavity," a depression in the upper jaw, a "sucking reflex" is triggered, and the infant or young child begins peristaltic movements of the tongue.

[0003] For this reason, it has become clear that pacifiers have the effect of satisfying the sucking reflex of infants and young children, and this effect promotes mental and physical relaxation for infants and young children. On the other hand, sound and music attract the attention of infants and young children. Patent Document 1 discloses a device that allows infants and young children to feel this music.

[0004] The musical pacifier in Patent Document 1 provides a musical pacifier that transmits sound vibrations directly to the baby's ears through the baby's jaw. Specifically, it includes a pacifier frame, a nipple located on one side of the frame, and a housing located on another side of the frame. The housing contains a music IC and power supply, an insulating housing, and a vibration transducer. The insulating housing, made of a soft material, is used to insulate vibrations. The vibration transducer is used to convert pre-stored music into vibrations. The vibration transducer is located within the housing. The vibration transducer is connected to the music IC. A vibration tongue is used to transmit vibrations generated by the vibration transducer to the baby's jaw. The vibration tongue includes a contact portion of the vibration transducer within the housing and a tongue that protrudes from the housing and extends into the nipple.

DETAILED DESCRIPTION OF THE INVENTION

[0018] Preferred embodiments of the present invention will be described in detail below with reference to the drawings. The embodiments described below are preferred specific examples of the present invention, and therefore various technically preferable limitations are applied. However, the scope of the present invention is not limited to these aspects unless otherwise specified in the following description to the effect that the present invention is specifically limited. Furthermore, in each drawing, similar components are designated by the same reference numerals, and detailed descriptions thereof will be omitted where appropriate.

[0019] <First Embodiment> 1 and 2, the pacifier device 100 of the present invention includes a main body 101 (the pacifier frame) made of hard plastic, a silica gel nipple 102 located on a first side of the main body 101 (the pacifier frame), and a vibration module located on a second side (opposite the first side) of the main body 101 (the pacifier frame). A hole is located in the main body 101 (the pacifier frame). The rear of the silica gel nipple 102 passes through the hole and contacts the second side of the main body 101 (the pacifier frame) via a protrusion 104 at its rear.

[0020] The vibration module is located on the second side of the main body 101, which is the frame of the pacifier, and includes a housing 105 that connects to the main body 101. A locking eye 106 is located on the second side of the main body 101, and a locking tab 107 is located on the housing 105. The locking tab 107 and the locking eye 106 fit together and are removable. If the nipple 102 needs to be cleaned, this can be done by removing the housing 105 from the main body 101. This can avoid shorting or damaging the electronic circuits in the housing 105.

[0021] The first through-hole is located within the locking tab 107 of the housing 105. The relaxing internal body sound generating unit 108 and a housing 109 used to block vibrations are located within the housing 105. The vibration transducer (vibration generating unit) 110 and the jaw vibration transmitting unit 111 are located within the housing 109. The housing 109 is made of a soft material such as rubber or silica gel. The housing 109 covers the vibration transducer 110 and the jaw vibration transmitting unit 111, allowing them to float within the housing 105. This dampens the vibration of these two components and prevents the vibration from being transmitted to the housing 105 and the main body 101, thereby preventing resonance and sound generation.

[0022] As shown in FIG. 2, there is a gap between the housing 109 and the relaxation body sound generating unit 108, and they do not contact each other. The housing 109 has a protrusion 112 that protrudes from a first through-hole in the locking eye 106 of the receiving portion 105. A second through-hole is located in the protrusion 112 of the housing 109. The vibration transducer 110 is located in the receiving portion 105, electrically connected to the relaxation body sound generating unit 108, and converts pre-stored sounds into vibrations. The jaw vibration transmitting unit 111 forms a "T"-shaped cross section. The contact portion contacts the arc vibration surface of the vibration transducer 110. When the vibration transducer 110 vibrates, it transmits the vibration to the jaw vibration transmitting unit 111.

[0023] The pacifier 100 includes a switch button 115 and a USB terminal 116 that connects to the relaxing internal body sound generating unit 108. The switch button 115 extends from the housing 105. When the switch button 115 is pressed, the relaxing internal body sound generating unit 108 is powered on, heart sounds and the like are emitted, and the jaw vibration transmitting unit 111 vibrates. When the switch button 115 is pressed again, the heart sounds and the like stop. The pacifier 100 can be recharged via the USB terminal 116 by connecting the relaxing internal body sound generating unit 108 to an external power source via a USB 120 and a cable 121.

[0024] When a baby sucks on the nipple 102, their teeth or jaws come into contact with the jaw vibration transmission unit 111 via the nipple 102, and pre-stored heart sounds and other sounds are transmitted to the baby's jaw through vibrations, and then to the baby's inner ear. This allows the baby to hear heart sounds, fetal movements, and other sounds. Since the housing 109 is made of a soft material, the vibrations are insulated. This prevents the sound from being transmitted outside by resonance with other parts of the pacifier. Surrounding people cannot hear the sound. As a result, the pacifier 100 is suitable for places where silence is required.

[0025] <Embodiment 2> As shown in Figures 2 and 3, pacifier 100a comprises a main body (plastic) 101 that serves as the seat for nipple 102 (located above chin rest 125, described below; not shown in Figure 2), and an L-shaped chin rest (plastic) 125 that rests on the infant's chin and is connected below main body 101. Nipple 102 is formed with a hardness equivalent to that of a baby bottle nipple, taking into consideration factors such as hardness and thickness. Examples include thermoplastic elastomers such as silicone rubber, isoprene rubber, natural rubber, and polypropylene. This configuration prevents danger even when the infant lies face down.

[0026] The relationship between the chin contact portion 125 and the relaxing internal body sound generating unit 108 will now be described with reference to Figure 2. As shown in Figure 2, the chin contact portion 125 is an integrated unit consisting of an L-shaped portion that fits under the chin and a T-shaped protrusion that fits toward the relaxing internal body sound generating unit 108. A piezoelectric element portion 130 is attached to the surface of this T-shaped protrusion. Therefore, since no transducer (metal diaphragm), coil, or magnet is used, it is small and lightweight.

[0027] The chin rest 125 preferably has a vertical length of 15 mm to 30 mm and a horizontal width of approximately 10 mm to 25 mm (for S, M, and L sizes). Meanwhile, the relaxing internal body sound generator 108 has a computer section 108a provided therein. This computer section 108a and the T-shaped protrusion are covered by a housing section (plastic) 105. Furthermore, the housing section 105 is provided with a switch button 115 for starting or stopping the computer section 108a, a USB connector 136a for attaching a USB cable, and the like. It is preferable to provide an appropriate air hole in the housing section 105.

[0028] Fig. 4 is a schematic diagram of the computer section 108a. The computer section 108a is provided in the relaxing internal body sound generating section 108. As shown in Fig. 3, the computer section 108a is made up of an MPU (microprocessor unit) 131, a memory section 132 that stores relaxing internal body sounds, etc., a charging section 134, a vibration information converting section 133 that converts sound into vibration information, an acquiring section 135 that acquires internal body sounds such as heart sounds and fetal movement sounds, etc., and these are connected to a USB connector 136a.

[0029] The storage unit 132 stores multiple types of maternal heart sounds, fetal movement sounds, etc. For example, heart sounds for morning (6:00 to 7:00 or 8:00), afternoon (12:00 to 13:00), evening (17:00 to 18:00), night (10:00 to 11:00), etc. are stored. Alternatively, instead of heart sounds, fetal movement sounds when the fetus is in the womb may be collected with a stethoscope or the like and stored in multiple numbers as described above. Alternatively, multiple relaxing internal sounds may be stored. These sounds are collectively referred to as relaxing internal sounds in this embodiment.

[0030] Furthermore, this embodiment has a charging unit 134, which charges a rechargeable battery with power from a USB connector 136a. Meanwhile, when switch button 115 is turned on, the program of MPU 131 generates any of the relaxing internal body sounds stored in storage unit 132, converts this generated signal, and outputs it to vibration generating unit (piezoelectric element, etc.) 137.

[0031] The vibration generating unit (piezoelectric element, etc.) 137 vibrates with the power of this generated signal. Therefore, this vibration is transmitted through the T-shaped convex portion (plastic) to the chin contact portion 125 in FIG. 2. This transmission is then transmitted to the chin of the infant, etc. Note that the selection and setting of the relaxing internal body sounds described above is preferably set using a smartphone, which will be described later.

[0032] <Third Embodiment> Fig. 5 is a schematic diagram of a pacifier system 199a according to the third embodiment. The aforementioned relaxing internal body sound selection function is preferably provided as an application for a smartphone 200 (mobile terminal) as shown in Fig. 4. As shown in Fig. 4, this application comprises a relaxing internal body sound generation button 201, a relaxing internal body sound storage button 202, a relaxing internal body sound selection button 203, a relaxing internal body sound on button 204, a relaxing internal body sound off button 205, etc.

[0033] As shown in FIG. 6 , the sound collection microphone 300 is attached near the heart of the mother 400 and connected to the smartphone 200 via the USB cable 301 and the USB terminal 302. The USB terminal 152 and the USB cable 121 are connected to the USB 120 via the USB terminal 152 and the USB cable 121. When the Relaxing Internal Sound Generation button 201 is pressed, the app displays options (not shown) on the screen, such as morning (6:00-7:00 or 8:00), afternoon (12:00-13:00), evening (17:00-18:00), and night (10:00-11:00). The mother selects one of the options, the Relaxing Internal Sound Selection button 203. The collected heart sounds, fetal movement sounds, etc., are associated with the date and time, and the associated options are stored in the storage unit 132 by pressing the Relaxing Internal Sound Storage button 202 on the pacifier device 100.

[0034] The relaxing body sounds may be stored in the smartphone 200 without being connected to the relaxing body sound generating unit 108 of the pacifier device 100, and then stored again after a few hours or at a later date by connecting the smartphone 200 to the relaxing body sound generating unit 108 of the pacifier device 100. Meanwhile, the mother, father, grandmother, grandfather, sibling or other person may connect the smartphone 200 to the relaxing body sound generating unit 108 of the pacifier device 100 with a USB cable 121 and select a suitable relaxing body sound from the screen of the smartphone 200.

[0035] With this selection, the app will display options on the screen (not shown), such as morning (6:00-7:00 or 8:00), afternoon (12:00-13:00), evening (17:00-18:00), or night (10:00-11:00). The selector (mother, father, grandmother, grandfather, sibling, or other person) will look at the infant's condition and select the relaxing internal body music item that they deem appropriate. This selected relaxing internal body sound (data) is transmitted via USB cable 121 and stored in memory unit 132 by MPU 131.

[0036] When the selector presses the switch button 115 on the pacifier device 100, the MPU 131 plays back the relaxing body sounds stored in the memory unit 132 and outputs this playback signal to the vibration generating unit 110 or the piezoelectric element 137. The vibration generating unit 110 or the piezoelectric element 137 vibrates in response to this playback signal. This vibration is then transmitted to the infant's ear via the jaw vibration transmitting unit 111 or the T-shaped protrusion (plastic). This allows the mother, father, grandfather, grandmother, sibling, or even someone else to calm the infant down and put them to sleep. While the above embodiment describes turning the pacifier device 100 on and off with a switch, a relaxing body sound on button 204 and a relaxing body sound off button 205 are displayed on the smartphone screen as shown in FIG. 4, and these buttons may also be used for turning the device on and off.

[0037] <Fourth Embodiment> Fig. 7 is a configuration diagram of the computer unit 108b of the pacifier system 199b according to the fourth embodiment. As shown in Fig. 6, the computer unit 108b has a posture sensor 138 and a Wi-Fi unit 136b (hereinafter referred to as a short-range wireless communication unit). The posture sensor 138 defines an orthogonal coordinate system of X, Y, and Z, and outputs data indicating the directions of the coordinate axes to the MPU 131. The MPU 131 communicates with the smartphone 200 via the short-range wireless communication unit 136b, and sets a mutual identification code and protocol. When a request for posture data is received from the smartphone 200 via the short-range wireless communication unit 136b, the X, Y, and Z values ​​are transmitted to the smartphone 200 as posture data together with the date and time.

[0038] The smartphone 200 app displays a posture confirmation button (not shown) on the screen. When this posture confirmation button is pressed, the app transmits a posture request signal (smartphone identification code, short-range wireless communication unit identification code) and receives posture data from the pacifier device 100. The smartphone app has a standard three-axis coordinate system for the infant, and defines the XYZ of the posture data in this coordinate system. It then analyzes whether the infant is in a sideways position 206, a prone position 207, or a supine (normal) position 208, and displays the analysis result on the screen (see Figure 6). Therefore, even if you are far away, you can check whether the infant is lying on their back, side, or prone, ensuring safety.

[0039] Furthermore, it is also possible to appropriately combine embodiments 1 to 4. In this way, since the baby can continue to hold the pacifier in his / her mouth, it is possible to calm the baby mentally, suppress crying, and reduce physical strain, and it is also possible to maintain or promote the sucking reflex and oral stimulation necessary for oral feeding.
