Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an infant care device configured to facilitate a smooth transition of an infant from the womb to full awareness of the natural world. The infant care device consists of a hammock-like seat and a sound device that generates sounds and vibrations similar to heartbeats. It raises fundamental questions about the care of infants and makes significant advances in such care.

In recent years, various studies have shown that the way infants are treated in the first few days or months after birth, and the environment in which they are raised, can have a significant psychological impact on the infant after it grows up. This has been revealed from psychological research. In the womb, the fetus has a close symbiotic relationship with its mother, and as it grows, it gradually becomes aware of various sensory stimuli, especially sound, touch,
Becomes aware of movement and the air surrounding the fetus.

This cozy environment within the uterus provides the fetus with a feeling of protection and considerable palpable myokinesthetic stimulation.

From birth Iζ, the comfortable environment inside the womb suddenly changes into a completely new sensory world. The range of stimulation given to the fetus before birth suddenly increases. Recent research shows that the applied myokinesthetic stimuli such as touch and movement, spatial definition, holding and rocking create impulses in the infant's nervous system that are transmitted to the cerebellum. stimulates the development of the cerebellum. This is a process that occurs during the first two years of a child's life. The cerebellum is the only part of the brain where brain cell proliferation continues for a long time after birth, so stimulation of the cerebellum is extremely important. It has been suggested that receiving such stimulation enables smooth and integrated muscle movements after growth. For example, ballerinas display the highly sophisticated function of the cerebellum, which controls the sashiko muscle with exquisite precision. Therefore, myokinesthetic stimulation of infants is extremely important. However, modern infant care methods often do not provide such stimulation. In fact, many of the products available to parents today are designed to eliminate the need for parents to engage in activities that provide myokinesthetic stimulation to their infants.

Human infant development has been described as consisting of two distinct gestational stages. The first stage is a nine-month period inside the uterus, during which uterogestation occurs.
ation). The second period is the first nine months outside the uterus, and is the first nine months outside the uterus.
rogestation). During ectopic pregnancy, the infant grows to the point where it can crawl.

During both stages, the fetus and infant's primary sensory system (p
Stimulation of the primary 5 sensory system appears to be extremely important. The myo-kino-sensory stimulation provided to infants during ectopic gestation - the senses of light, sound, smell, taste, etc. that constitute the cuddling love that should be the birthright of every child - is a normal, well-adjusted human sensation. It now appears to be of fundamental importance in development. To name a few examples, tactile stimulation appears to initiate all of an infant's innate reflexes. Touch is an infant's best teacher. Touch not only helps infants' emotional stability, but it also appears to actually support the development of their brains and nervous systems.

For these reasons, it is important to hold the infant, talk to the infant, and provide various sensations of touch to the infant. Tactile stimulation has a calming effect on infants and organizes the infant's sensory system - sensory integration.
It seems to help the process called ``integration''. Another example is touching an infant.
Providing infants with kinesthetic stimulation and kinesthetic stimulation appears to be essential for infants' social, emotional, and intellectual growth. Infant Kinesthetic System - Vestibular Sensory System (
vestibular sensory system)
Stimulating the so-called - brings joy and enjoyment to infants. Cuddling improves infant emotional stability (e.g.
motional 5ecurity) develops. Additionally, holding an infant appears to stimulate the thymus gland. The thymus gland is responsible for infant growth and the immune system (immu).
ne system). Placing the infant in an environment that resists the infant's movements but does not stop them allows the infant to stretch and contract muscles and exercise the muscular and skeletal system.

During ectopic pregnancy, that is, for the first nine months after birth, infants placed in covered cradles or cribs provide little stimulation. Because in many families today, both parents work, they are away from their infants for long periods of time, and when they return home tired, they compete with each other for the infant's attention. Many infants suffer from being deprived of essential sensory stimulation for long periods of time. This may cause the infant to cry for a long time, which can lead to serious psychological problems in the infant's life.

Clearly, parents have worked hard for centuries to negate the physiological needs of their children, especially in the first few months after birth. In animals such as kangals or possums, which give birth to young in the uterus, the female is equipped with a pouch that provides the primary sensory stimulus to the infant during ectopic gestation. For centuries, parents have placed infants in covered cradles or cribs to quickly adapt the infant's body's natural rhythms and cycles to suit the parents' needs. Particularly in recent years, infants have been provided with less and less tactile muscle-kinesthetic stimulation due to the convenience of their parents. The major cause of psychological problems is a flaw that is becoming clear.

Therefore, the basic purpose of the infant care device of the present invention is to
The aim is to promote and encourage the normal development of the infant's body, brain and mind by providing tactile myo-kinesthetic stimulation to the infant's primary senses.

Achieving those goals is always the first priority for parents.
It was important. The present invention appears to have made a significant advance in this regard.

The infant care device of the present invention - appears to consist of a hammock that includes a sound device that produces a sound that apparently resembles a heartbeat. As will be apparent from the detailed description of the invention that follows, these two parts work together in a simple but surprisingly effective manner to provide support to the infant during ectopic pregnancy, particularly to the infant's main body. Provide a rich environment of tactile muscle-kinesthetic stimulation. Such an environment is of great benefit in promoting the natural and normal development of infants.

A hammock includes a sheet of flexible material.

The sheet is not only soft, but also flexible, so as to provide tactile stimulation to the infant and conform to and deform into various shapes that allow the infant to move, move, and define the space around it.
Try to make it as woven as possible to give it a rough feel. Support means are provided for holding the sheet in various positions from a relatively flat position to a deeply recessed or hollowed position. Thus, the seat can be positioned to rock and hold the infant tightly, and from a pocket that mimics the environment cradling a fetus in the womb, to an open flat position where the infant is exposed to the surrounding environment. The transition can be made smoothly. Preferably, the support device will allow the seat to rock back and forth in response to the infant's movements, continuing to provide the sensory stimulation of movement that was provided to the fetus during gestation. vestibular sensory stimulation

coordination) is strengthened.

It is convenient to use polygonal, preferably hexagonal, sheets made of stretchable terry cloth panels. Further, in order to enable the seat to be connected to the rails of a frame-equipped infant bed in any desired shape, it is preferable to attach support means made of strings to the corners of the seat.

A thick flash pile can be attached to one side of the sheet to provide another tactile stimulus. Further, it is preferable to provide a receptacle or pocket in the seat for attaching an audio device.

The acoustic device of the present invention generates audible and vibratory impulses that closely resemble the normal, natural beating of the human heart. The audio device is housed inside a case and is powered by batteries. A sound generator is used to make the case containing the sound device beat in a manner similar to the beating of a human heart.
The audio device includes a circuit device for driving the circuit, preferably composed of a solenoid. The audible and vibrational impulses generated by the sound generator striking the case are
The information is transmitted through the seat to the infant wrapped in the seat. A circuit arrangement for producing the output necessary to mimic the beating of a human heart should preferably consist of a series of logic components, each consisting of a pair of closely spaced components. pulses, and after a time sufficiently longer than the pulse interval of the pair of pulses has passed, generate another pair of pulses separated by a narrow interval, and then generate another pair of pulses separated by a narrow interval. The logic components are electrically interconnected to generate a further pair of pulses after a sufficiently long period of time has elapsed after a pair of pulses.

The solenoid's coil is energized by the output of the circuit device to generate a magnetic field. The coil surrounds an armature, and the armature, magnetized by the magnetic field generated by the coil, magnetically attracts nearby magnetizable plates. The structure and physical characteristics of the solenoid are such that the armature attracts the plate or magnetically attracts the plate with a force not so great as to cause the plate to contact the armature. Also, the plate is armature 1
The mass of the plate should be preferably sufficient so that its movement toward and away from the armature will generate vibrations sufficient to produce audible and tactile impulses within the case in which the solenoid is mounted. Enlarge.

The infant care device of the present invention is simple and effective and provides an ideal environment for a wide range of infants, especially during ectopic pregnancy. As explained in detail later,
The components of the infant care device of the present invention work together to provide the newborn with sufficient palpable myokinesthetic stimulation for the newborn's primary senses during the ectopic pregnancy period. The infant's tactile, kinesthetic, spatial and auditory senses are particularly well stimulated by the cooperative function of the parts of the device according to the invention. Sensory integration by infants is fostered by the device of the present invention.

In summary, the device of the present invention provides a uniquely enriched environment for newborn infants, which is important for infant development.

Hereinafter, the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, the infant care device of the present invention has a seat 2
has. The seat 2 is attached to the rails 4 of a canopied infant bed 6 by support means such as strings 3. In order to provide tactile stimulation to the infant, the seat 2 is preferably made of a soft but pliable material that provides a textured feel, such as stretchable terry cloth. By supporting the seat 2 in a hammock-like manner as shown, a pocket or depression is formed in the central portion for receiving the infant. A fur-like deep pile panel 8 that stands up on one side of the sheet 2 is sewn as much as possible in the center part. Terry cloth seats and pile panels provide a range of different sensory and tactile stimuli to the infant. , much different from a cold and relatively smooth surface.

The importance of tactile stimulation in infant development was discussed earlier.

The sound device or sound generator 10 is preferably placed in a pocket 11 sewn into the seat 2. By producing audible and palpable (i.e., vibratory) impulses similar to the beating of a human heart, this acoustic device reproduces the normal, smooth sound pattern that the fetus is constantly exposed to during utero gestation. produce very similar acoustic patterns. Such a sound pattern not only promotes healthy and deep sleep in infants, but also encourages the development of music appreciation skills after adulthood. The acoustic device 10J will be explained in detail later with reference to FIGS. 4 to 6.

The sheet is preferably polygonal in shape, with relatively flat or acutely angled side edges, and supporting means are attached to the corners. The support means includes several adjustable lace connections as shown in FIG.

It is convenient to make the sheet hexagonal, and the strings for supporting the sheet are attached to each corner of the hexagon.

The warp and weft threads of the panel material are the main longitudinal and main transverse axes of the sheet ζ
ζ By cutting the panels so that they are generally parallel and with precise side edges between each corner, the baby's weight tends to create bias in the panels;
In addition, the resistance of the panel to the infant's movements can be increased. By providing a corner in the middle of the sheet in the longitudinal direction,
Long side walls of the hammock are formed at the corners, increasing safety for the infant and increasing the environmental space for the infant bed, facilitating the infant's ability to discern the surrounding space. The middle part between the support strings of the seat does not change much when the baby is placed on the hammock, so the sound device should be placed in that part as much as possible. The pocket lightly receives the acoustic device and transmits vibrations well into and along the seat. Also, finish the edges of the sheet with tape 12 as much as possible. The tape terminates in a loop or string at each corner of the sheet.

FIG. 2 is a perspective view of a portion of the laces 3 illustrating the preferred manner in which the corners of the seat are adjustably attached to the rails of an infant bed. Each connector includes a tape loop portion 13 and a tape lace portion 15. A tape loop 13 is formed at one end of the finished side edge of the sheet and attaches a pair of rings 14 to the corners of the sheet. A tape string 15 is formed at the other end of the finished edge of the sheet. This string part 15
wrap around the rails of the infant bed, then wrap one ring once before passing it under the other ring as shown. The rings combine with the laces and hold the laces to form adjustable loops for attaching the corners of the seat to the infant crib.

This support means is easy to tighten and safe.

Increasing the tension on the lace portion 15 only causes the ring to hold the lace tighter. The tension in the string and loop is distributed along the sheet by the finished side edges of the sheet.

A hammock composed of a seat and a string part is
dimensions of the seat so that it can be adjusted to various positions from a relatively flat, spread-out position as shown in Figure 3b, to a more recessed sleeping position as shown in Figure 3b, or a deep pocket as shown in Figure 3c; Try to select the length of the string part for the baby bed as much as possible. In the deep pocket position of the seat, it is convenient to connect the seat to the infant bed in a criss-cross pattern such that the longitudinal dimension of the sheet extends in the lateral direction of the infant bed. Also, 3rd a

In order to allow the short side of the sheet to be shortened when the sheet is placed in the pocket position as shown in Figure 3c, a ve-Icro (trade name) 17 or snap-like material is attached along the short side of the sheet. It may be convenient to provide other attachment means. By doing this, an infant placed in a hammock attached to an infant bed in a deep pocket position can be securely held in the hammock, and the infant will receive a stronger feeling of being held. be able to. In this way, this hammock is soft and warm.
It can provide a dark, quiet and cozy place for infants.

The hammock resists the infant's movement, but stretches and recesses to allow enough movement for the infant to exercise the infant's muscular and skeletal systems and improve the infant's sense of touch. provides important tactile stimulation.

As the infant grows, the position of the seat and its attachment to the infant crib can be adjusted to gradually open the seat from the position shown in Figure 3C to the position shown in Figure 3a. Recent research results show that holding and sensory stimulation can greatly stimulate infant growth, provide infants with a sense of security, nurture the infant's primary sensory system, and maintain the infant's normal psychological well-being. Strengthen development.

Although the seat is shown mounted between the rails of an infant sleeper, various other support devices,
Of course, the support means are sufficiently simple that the seat can be fitted between the side edges of a portable infant bed, for example. Further, a deep pile panel 8 is preferably provided on only one side of the seat so that the seat can be turned over and the tactile stimulation given to the infant can be changed at any time. Furthermore, the panel 8 and the terry cloth sheet 2 are preferably made of washable materials. Most infant cribs include rails that can be raised and lowered relative to the surface of the pinerest, so that when the hammock is in either of its positions, especially the position shown in Figure 33, the infant will not rest on the pinerest. Jζ, the position of the rail can be adjusted in relation to the manotress lζ so that it can be reached somehow. This puts the infant in a flat stomach sleep position.
ing position), and
By simply placing the infant directly on the manotress 16, as is now common practice, the infant can be moved from the fully cradled position shown in Figure 3c to the position shown in Figure 3a. and then finally to a fully flattened position such as that which can be obtained by flattening the padding sheet over the surface of the pine mattress 16. The result is a gradual and advantageous transition from the uterus to the external world during the ectopic gestation period of infant development.

A preferred acoustic device or generator 10 is shown in FIG. As shown, the components of the acoustic device 1° are preferably housed within a heart-shaped case 20 (other shapes may be used if desired). In FIG. 4, the lid of the case 20 is removed to show the parts of the audio device 10.

Generally, the components of the audio device 10 include a battery 22, a circuit board 24 that supports the main electrical components of the audio device, and a solenoid vibration generator that is attached to the side of the case 20 with screws or adhesive to transmit vibrations to the case 20. machine 26.

A switch 28 is also provided.

A block circuit diagram of a preferred example of the electric circuit device used in the audio device 10 is shown in FIG. This circuit arrangement is a simple syncopated J circuit.

The positive potential of battery 22 is applied to one input terminal of exclusive-OR gates 32 and 34, respectively. Since the other input terminal of gate 32 is at a low voltage state, gate 32 produces a positive output. Its output is applied to the other input terminal of gate 34 to cause gate 34 to have a zero or ground output. The output of gate 32 is connected via series connected resistors 36, 38 to series connected capacitor 4.
0°42 to charge their capacitors. As the series connected capacitors are charged, the voltage across them increases, so that a sufficiently high positive voltage is provided to the other input terminal of gate 32 through resistor 44, so that gate 32 Generates a zero or ground output. Since its zero output is applied to the other input terminal of gate 34, gate 34 produces a positive output. The positive output of gate 34 is applied through resistor 46 to capacitor 48 to charge it and to one input terminal of exclusive-OR gate 52. As the output of gate 34 charges capacitor 48, one input terminal of exclusive-OR gate 54, which is connected to the common junction of resistor 46 and capacitor 48, receives a sufficiently high positive voltage to produce a positive output ( Since the other input terminal of gate 54 is grounded, it is always in the zero state). When the output of gate 54 becomes positive, gate 5
Since positive inputs are given to the two input terminals of gate 52, gate 52 stops generating a positive output.

The output of gate 52 is connected to transistor 6 via resistor 60.
2 to make that transistor conductive, allowing current from the battery to flow through the coil of solenoid 26 to ground. Then, after a short delay of about 2 to 3 milliseconds, the output of gate 52 drops to zero, and transistor 62
becomes non-conducting. Then, the current flowing through the coil of the solenoid 26 disappears. Current flows due to the back emf created in the coil when the current dissipates, but that current is shunted by diode 64 so that no harmful reverse bias voltage is applied to transistor 62. A diode 66 should be placed between the battery and the logic element, since it is very easy to destroy the logic element if an inappropriate current is applied.
be connected in series.

The purpose of this circuit is to work with the solenoid vibration generator to
It is the production of a pounding sound that closely resembles the audible and palpable (concussive) impulses of the human heart. The sound is characterized by a pattern of two pulses followed by a short interval followed by a long time interval or pause, and this pattern repeats. Each pounding sound is generated during a conduction cycle of transistor 62. For example, the first thump is initiated by gate 34 being opened, causing gate 52 to open. Gate 54 is then opened after a short delay. When the output of gate 54 is applied to gate 52 along with the output of gate 34,
Gate 34 is closed. Then after a short delay Gate 32
is opened, and when gate 34 is closed, gate 52 is opened again. When capacitor 48 discharges through resistor 46 and the voltage across capacitor 48 drops to a value sufficient to remove the positive bias applied to the input terminal of gate 54, gate 52 is closed and its gate is closed. The output of is matched to the grounded output of gate 34.

The interval between these two conduction cycles is determined entirely by the rate of discharge of capacitor 40.42, which is discharged through diode 68 and resistor 36, respectively, to the grounded output of gate 32. There is preferably a delay of 0.4 to 0.7 seconds between the two conduction operations of the transistor 62.

Since the two inputs to gate 34 are positive at this point, the outputs of gates 34.52.54 are all zero or ground. The positive output of gate 32 is connected to resistor string 36
．． 38 to charge the capacitor 40.42. The resistance values of these resistors and resistor 38 are determined at the end of the last mentioned conduction cycle of transistor 62 and when applied to the other input terminal of gate 32 via resistor 44. approximately 1.0 to 1.2 between when the positive potential on capacitor 40 reaches a value sufficient to cause gate 32 to close.
Select as much as possible to produce a delay time of seconds. When gate 32 closes, the conduction cycle described above begins again.

The conduction states of the four gates during each stage of operation described above - here stages A, B, and C for convenience.

The solenoid includes a coil 72 wound around a magnetizable armature or core 74 and a magnetic plate 76 . The magnetic plate is attached to a resilient mount consisting of a spring-like exterior panel 78 and a base 80. This mount holds the magnetic plate 76 at a slight distance from the surface of the iron core 74.

A weight or inertial element 82 may be attached to the outer surface of magnetic plate 76 by adhesive or other convenient means.

Next, the operation will be explained. A pulse train generated by the electrical circuit arrangement shown in FIG. 5 is applied to the solenoid coil 72 to magnetize the iron core 74 and cause the magnetic plate 76 to be attracted and then released. The mass or inertia of the inertial element 82 interferes with the magnetic attraction of the magnetic plate to the core, causing the magnetic plate 76 to resonate somewhat with the spring arm 78. The impedance and resonance of the disturbance are controlled by the operating phase, the duration of the pulses applied to the coil, the mechanical properties of the magnetic plate, the weight, and the spring panel. More specifically, the solenoid has unique characteristics, such as the spring constant of the arm 78 and the distance between the opposing surfaces of the magnetic plate 76 and the iron core 74. This electrical circuit arrangement is configured to generate the pulses described above. The characteristics of the solenoid and the characteristics of the electrical circuit device are correlated so that the magnetic plate can move far enough to avoid hitting the iron core in order to produce a series of distinct impulse sounds and vibrations similar to the beating of a human heart. I have to let it happen.

When the magnetic plate hits the iron core, there is simply a clicking sound. The inertia provided by the weight 82 prevents the magnetic plate from hitting the iron core. The characteristics of this acoustic device can be adjusted, for example, by slightly bending element 80 or arm 78 to adjust the spacing between magnetic plate 76 and iron core 74.

By appropriately adjusting their characteristics, vibrations can be created within the case 20 that closely resemble the pounding of a human heart.

It is important to consider the characteristics of the solenoid and the way the circuit applies it to the magnetic plate 76.

Because the preferred circuit uses primarily logic elements, most of the current drawn from battery 22 is current flowing through the coil of solenoid 26, and that coil current remains constant while transistor 62 is in its conducting state. only flows. Each conduction period should preferably be 2 to 3 milliseconds. At a rate of 60 pulses per minute, a typical 9 volt battery can be used continuously for 800 hours. This is a period slightly longer than one month.

As described above, the audio device 10 is placed as far as possible into the pocket 12 provided in the seat 2. The vibrations generated by the acoustic device are transmitted through the seat 2 to the infant sleeping on the seat, and work together with the properties of the seat to provide the infant with an excellent transitional environment. Although the seat cradles the infant, the infant can still roll, kick, and stretch. The acoustic device produces rhythmic sounds and vibrations similar to perhaps the most important sounds in the womb, calming and reassuring the infant.

As explained above, the infant care device of the present invention improves the body, brain, and mind of an infant during ectopic pregnancy by stimulating the main sensory systems of the body, including at least the following basic senses. It encourages and promotes growth.

(1) Touch - This sensation is what initiates all reflexive actions in the infant. Touch develops emotional stability, but actually strengthens the growth of the infant's brain and nervous system. Feel is therefore of fundamental importance. The terry cloth and pile panels of the device of the invention directly and continuously stimulate the infant's sense of touch.

(2) Sounds, especially familiar sounds that provide a sense of security, also appear to be important for infants. The infant emerges from the womb, an environment in which the constant, rhythmic beating of the mother's heart provides constant comfort. To an infant wrapped in a hammock formed by a sheet, the acoustic device provides audible and vibratory impulses that mimic the infant's rhythmic heartbeat. Studies have shown that providing such sound and vibration impulses significantly reduces infant crying and significantly increases body weight. Of course, the acoustic device can be used independently even after the sheet forming the nonmonoque is no longer needed. The sound device continues to provide the infant with a sense of security, as just described.

(3) Kinesthetic sensation is the infant's other major teacher.

Kinesthetic sensation is also important for the development of the infant's brain and nervous system. Due to the rocking made possible by the hammock formed by the seat of this device and stimulated by the movements of the infant, the newborn baby is to some extent be able to move. The curved shape of the hammock allows the infant to move and stretch in a normal natural manner against some resistance and in a manner that can be adjusted by simply adjusting the shape of the hammock provided by the device. can. Particularly in the deep pocket position provided by the hammock, movement of the hammock induces a free and reassuring rocking motion. The rocking has been shown to calm infants and promote quiet, restful sleep. In fact, this vestibular stimulation works in conjunction with an acoustic device,
It has been found to dramatically reduce and almost immediately resolve incessant crying in newborns in some cases.

(4) Perceiving the surrounding space is another major teacher of infants. In the womb, the fetus lived in a comfortable, accommodating, confined space.

After birth, infants naturally feel safe when held in this way, but they even seem to require the continuation of this spatial restriction during the period of extrauterine study. The device's hammock allows the infant to push and stretch against the sides of the hammock, helping the infant to recognize the space around the infant, promoting the infant's relationship to that space, and stabilizing the infant. , integrate.

Additionally, this shape is associated with infant flailing (fl-ail).

ng) and is apparently responsible for tension and tension-induced strain in many infants.

As explained above, the infant care device of the present invention provides a rich environment that continues all the main stimuli during the extrauterine gestation period and provides the basic stimulation needed during the crucial first months after birth. It provides stimulation to infants. The device of the invention facilitates training of the infant's joints and muscular system as well as the brain and nervous system.

The device of the invention aids in the infant's sensory integration and facilitates the infant's relationship to gravity as well. It is a valuable and unique aid in the infant's physical development and in the prevention of several mental disorders that appear to be directly related to the infant's lack of sensory stimulation and integration.
