Description

Infant head correction cap

Technical Field

The utility model relates to a cap, in particular to a baby head correcting cap.

Background

The sleeping postures of the newborn baby generally include back sleeping, side sleeping and face-lying sleeping. Wherein, it is possible to lead to sudden infant death syndrome to lie prone to sleep, mainly think that lie prone to sleep can cause infant's brain oxygen deficiency because head muscle development and lung muscle development are not perfect, lie prone to sleep in addition, can influence neonate's blood circulation, lead to the brain oxygen deficiency, cause sudden death. If the newborn is put to sleep in a lateral position or in a prone position, the baby is often suffocated in a greatly increased risk due to the posture. Therefore, the newborn is usually in a flat lying position, i.e., in a correct posture for sleeping on the back. When the neonate lies flat and sleeps, children often breathe very smoothly to when the neonate lies flat, the muscle impetus of health back is relatively more even, also helps the comfort level of children's health, and it is also more convenient when the family and neonate carry out the interdynamic.

The head of the infant consists of a skull and a face, and the skull consists of a skull top, a skull base and a skull cavity. All bones of the skull top belong to flat bones, the frontal bone is in front, the occipital bone is in back, the left parietal bone and the right parietal bone are between the frontal bone and the occipital bone, and all bones of the skull top are jointed by cranial sutures. The skull bone is membrane internalized bone in the embryonic development period, is not completely ossified at birth, is not completely closed by the suture of the skull, and still retains membrane structures such as anterior fontanel and posterior fontanel at certain parts. Because the skull is not completely ossified, the bone is soft, the bone suture is not closed, the head of the newborn is large and occupies about 1/4 of the body, and the neck muscle of the newborn has no force to rotate the heavy head, when the bone slice at a certain part bears the pressure of the whole head for a long time, the growing shape of the bone slice is influenced.

Thus, although the shape of the infant's head is largely determined by innate genetic factors, acquired development is also greatly affected. It has been found that up to 30% of normal infants are prone to head deformation, the most prominent cause of which is poor sleeping posture. The head shape of the infant just born is perfectly round, and researchers find that before the age of 1 year, the infant sleeps on the back for a long time to form a flat head and a pancake face through the study on the sleeping posture of the infant; if the side-sleeping time is too long, the head becomes long and narrow and the face becomes slender.

Since the newborn is in a sleeping state from morning to evening and cannot turn over, parents need to pay attention to change and adjust the head orientation of the newborn frequently, generally speaking, adjustment for 1 time every 4 hours is more suitable, and the labor intensity of the parents is greatly increased.

Then, the cap body 1 is worn on the head of the infant, the left airbag 31 and the right airbag 32 are padded on the opposite sides of the back of the head of the infant, and the head of the infant is placed on a soft cushion such as a pillow. When the speed reaches 1:00, the first time controller 51 energizes the first electromagnet 381, under the action of the attraction force of the first electromagnet 381, the valve moves towards the first electromagnet 381 until the baffle 384 is attracted by the first electromagnet 381, at this time, the baffle 384 is blocked between the first air channel 372 and the air inlet channel 371, so that the inflator 39 is prevented from ventilating the first air channel 372, the first sealing block 385 is separated from the first air outlet 374, and the second sealing block 386 seals the second air outlet 375, so that the air entering the second air channel 373 is prevented from being exhausted through the second air outlet 375; when the flow rate reaches 1:00, the inflator 39 operates to ventilate the air inlet channel 371, the air in the air inlet channel 371 enters the right air bag 32 through the second air channel 373 and the second air pipe 34 in sequence to inflate the right air bag 32, and the right end of the back of the baby is gradually lifted in the process of inflating the right air bag 32, so that the head of the baby deflects towards the left by a preset angle; after the right air bag 32 is inflated, the inflator 39 stops operating, so that the head of the infant maintains a leftward deflected posture.

When the speed reaches 5:00, the first time controller 51 de-energizes the first electromagnet 381 and de-energizes the second electromagnet 382, the valve moves towards the second electromagnet 382 under the action of the attraction force of the second electromagnet 382 until the baffle 384 is attracted by the second electromagnet 382, at this time, the baffle 384 is blocked between the second air passage 373 and the air inlet passage 371, so as to prevent the inflator 39 from ventilating the second air passage 373, and the first sealing block 385 seals the first air outlet 374, so as to prevent the air entering the first air passage 372 from being exhausted through the first air outlet 374, the second sealing block 386 is separated from the second air outlet 375, when the speed reaches 5:00, the inflator 39 operates to ventilate the air inlet passage 371, the air in the air inlet passage 371 enters the left air bag 31 through the first air passage 372 and the first air pipe 33 in sequence, so as to inflate the left air bag 31, and during the inflation of the left air bag 31, gradually raising the left end of the back of the baby so as to enable the head of the baby to deflect towards the right by a preset angle; during the deflection of the head of the infant to the right, the head of the infant presses the right air bag 32, and the air in the right air bag 32 enters the second air passage 373 through the second air tube 34 and finally is discharged to the outside from the second air outlet 375 and the air hole 21 of the visor 2, so as to allow the right air bag 32 to return to the uninflated state. After the left air bag 31 is inflated, the inflator 39 stops operating, so that the head of the infant maintains a posture of deflecting to the right. Thus, the left air bag 31 and the right air bag 32 are alternately inflated and deflated, so that the baby whose sleeping posture is difficult to adjust by self-strength can be assisted, and the head of the baby can automatically deflect within a set time.

It is understood that the method of using the infant head correcting cap is not limited to the present embodiment, and for example, for an infant whose head side has a flat phenomenon, the holding times of the left and right deflected sleeping postures may be set to be different to assist in correcting the shape of the infant's head. For example, when the left side of the head of the baby is flat, the baby can keep the head deflected towards the right for a long time to assist in correcting the shape of the head of the baby.

It is understood that the inflator 39, the controller, the three-way valve 36, the first air tube 33 and the second air tube 34 may be disposed outside the cap body 1, and the left air bag 31 and the right air bag 32 may be disposed on the outer surface of the cap body 1 as long as they can be supported below the back of the head of the infant.

The above description is intended to describe in detail the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the claims of the present invention, and all equivalent changes and modifications made within the technical spirit of the present invention should fall within the scope of the claims of the present invention.
