Description

Technical Field

[0001] The present invention belongs to the technical field of medical supplies, specifically a neonatal head shape correction pillow. Background Art

[0002] Abnormal neonatal head shape is a common problem during the infant development period, mainly caused by fetal compression, birth canal pressure, or long-term fixed sleeping positions after birth. Research shows that about 20%-30% of infants have varying degrees of skull asymmetry within 3 months after birth. If not intervened in time, it may affect cranial development and facial symmetry. In the early stage, it mainly relies on parents to manually adjust the infant's sleeping position, but it is difficult to continuously monitor in actual operation, and frequent intervention is likely to interfere with the infant's sleep cycle. Some families use cotton soft pillows or towel rolls to assist in fixation, but they lack mechanical support design and cannot evenly disperse the skull pressure. Even worse, it may cause the risk of airway obstruction due to the overly soft material.

[0003] Then, the utility model with the existing patent number CN214387032U discloses an adjustable neonatal head shape correction pillow, including a pillow body and a lateral pillow. A lateral pillow is arranged on the top surface of the pillow body. A pillowcase is arranged inside the lateral pillow. A neck protection and shaping area is provided below the pillowcase. An inflation port is opened at the rear end of the pillowcase. A sliding groove is opened below the inflation port. Adjusting knobs are arranged at both ends of the sliding groove. Filling cotton is arranged inside the pillow body. An airbag is arranged below the filling cotton. A chute is opened below the airbag. An adjusting roller is arranged on the surface of the chute. A positioning rod is arranged inside the adjusting roller. This utility model has the advantages of flexible use, convenient adjustment, improved comfort, reasonable structural design, convenient use, and easy promotion.

[0004] However, during the actual use of this device, only the angle of support is adjusted through the airbag, resulting in poor adaptability of the device and inability to adapt to newborns with overly large head shape differences. Moreover, only the correction of the arc groove cannot ensure effective correction in the longitudinal plane. It is necessary to perform adaptive head shape correction on newborns and improve the correction effect. Summary of the Invention

[0005] To solve the problems raised in the above-mentioned background art, the present invention provides a neonatal head shape correction pillow. By setting a micro motor and a winding drum, the device can put a flexible silicone head ring on the forehead of a neonate. Starting multiple groups of micro motors to drive the winding drum to wind up the elastic band, the traction direction is controlled by the coordinated operation of double motors to achieve vector adjustment in three-dimensional space and accurately act on the skull malformation area, so as to intermittently traction the neonatal head. The intermittent traction force can activate the osteoblast activity of the cranial suture and promote the local bone deposition rate. The contact layer of the flexible silicone head ring is made of medical silicone and coated with an antibacterial silver ion coating to correct the neonatal head shape. And by setting a screw rod and a nut, the device can drive the screw rod to rotate by rotating the nut, and then drive the positioning block to move and adjust its position. The second magnetic position sensor can detect the distance between each other through its own magnetic field. When the neonate moves around and causes the distance from the second magnetic position sensor to increase, the device will issue an alarm to prompt the parents that the position has shifted and remind the parents to correct the position of the neonate.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figures 1 to 8 shown, the present invention provides a neonatal head shape correction pillow, which includes a pillow main body 1. A positioning seat 2 is provided at the top end of the pillow main body 1. A correction airbag 3 is installed inside the positioning seat 2. An air inlet 4 is fixed outside the positioning seat 2. An adaptive mechanism 5 is installed at the bottom end of the positioning seat 2. A traction mechanism 6 is provided inside the positioning seat 2. A measuring mechanism 7 is installed inside the pillow main body 1. There are two groups of positioning seats 2, and the positioning seats 2 are symmetrically distributed about the central axis of the pillow main body 1. The input end of the correction airbag 3 is communicated with the air inlet 4, and the contact surface between the correction airbag 3 and the neonatal head is concave arc-shaped.

[0023] As Figures 1 to 8 shown, the adaptive mechanism 5 includes an extension plate 501 and a return spring 502. The extension plate 501 is fixed at the bottom end of the positioning seat 2. The return spring 502 is fixed outside the extension plate 501. The outer wall of the extension plate 501 is close to the inner wall of the pillow main body 1, and the extension plate 501 is slidably connected to the pillow main body 1. There are two groups of return springs 502, and the return springs 502 are symmetrically distributed about the central axis of the extension plate 501. A support airbag 503 is provided inside the pillow main body 1. The return spring 502 is used to squeeze the extension plate 501 and keep it in a moving trend outward. There are two groups of support airbags 503, and the support airbags 503 are symmetrically distributed about the central axis of the pillow main body 1. When the support airbag 503 expands, it squeezes the extension plate 501 and keeps it in a moving trend inward.

[0024] By adopting the above solution: by inflating the support airbag 503, the support airbag 503 squeezes the extension plate 501, and then adjusts the position of the positioning seat 2 towards the middle to adapt to newborns with different head circumferences.

[0025] As Figures 1 to 8 shown, the traction mechanism 6 includes a micro motor 601, a winding drum 602 and an elastic band 603. The micro motor 601 is installed inside the positioning seat 2. The winding drum 602 is fixed outside the micro motor 601. The elastic band 603 is provided outside the winding drum 602. There are four groups of winding drums 602, and the winding drums 602 are symmetrically distributed about the central axis of the pillow main body 1. The elastic band 603 is wound outside the winding drum 602.

[0026] As Figures 1 to 8As shown in the figure, a support ring 604 is sleeved inside the elastic band 603, and a flexible silicone head ring 605 is fixed outside the support ring 604. There are four groups of micro motors 601, and the micro motors 601 are symmetrically distributed about the central axis of the pillow body 1. There are two groups of support rings 604, and the support rings 604 are symmetrically distributed about the central axis of the flexible silicone head ring 605. The shape of the flexible silicone head ring 605 is circular.

[0027] Adopting the above scheme: By sleeving the flexible silicone head ring 605 on the forehead of the newborn, starting multiple groups of micro motors 601 to drive the winding drum 602 to wind up the elastic band 603, the traction frequency can be set to an intermittent mode or a continuous mode, and the traction direction is controlled by the cooperation of two motors to achieve vector adjustment in three-dimensional space and accurately act on the skull deformity area, so as to intermittently traction the head of the newborn. The intermittent traction force can activate the osteoblast activity of the cranial suture and promote the local bone deposition rate. When the traction direction is aligned with the skull growth axis, it can guide the bone plate to expand along the direction of least resistance, effectively correcting sagittal craniosynostosis or frontal bone asymmetry. The elastic traction band generates a gradual deformation when applying force, and the strain rate < 5% / s, avoiding ischemic necrosis of the skin caused by the rigid compression of the traditional helmet. The contact layer of the flexible silicone head ring 605 is made of medical silicone, the surface is covered with an antibacterial silver ion coating, and the ventilation holes adopt a bionic honeycomb structure, with a ventilation rate of 3000g / m² / 24h, significantly reducing the incidence of eczema.

[0028] As Figures 1 to 8 As shown in the figure, the measuring mechanism 7 includes a screw rod 701, a nut 702 and a positioning block 703. A nut 702 is fixed outside the screw rod 701. The screw rod 701 is rotatably connected to the pillow body 1. A number of anti-slip lines are arranged outside the nut 702, and the anti-slip lines are equally spaced about the central axis of the nut 702. A positioning block 703 is movably connected to the outside of the screw rod 701. An internal thread is provided on the inner wall of the positioning block 703, and the positioning block 703 is threadedly connected to the screw rod 701. The outer wall of the positioning block 703 is close to the inner wall of the pillow body 1, and the positioning block 703 is slidably connected to the pillow body 1. A first magnetic position sensor 704 is fixed to the top end of the positioning block 703, and a second magnetic position sensor 705 is fixed to the bottom end of the flexible silicone head ring 605.

[0029] Adopting the above scheme: By rotating the nut 702 to drive the screw rod 701 to rotate, and then driving the positioning block 703 to move and adjusting the position of the first magnetic position sensor 704. The first magnetic position sensor 704 and the second magnetic position sensor 705 can detect the distance between each other through their own magnetic fields. When the newborn moves around and causes the first magnetic position sensor 704 and the second magnetic position sensor 705 to move away, the device issues an alarm to prompt the parent that the position has shifted, and reminds the parent to correct the position of the newborn.

[0030] Working principle and usage process of the present invention: When the device is in use, the support airbag 503 is inflated, causing the support airbag 503 to squeeze the extension plate 501, thereby adjusting the position of the positioning seat 2 towards the middle to adapt to newborns with different head circumferences. When it needs to be unfolded, the extension plate 501 is deflated. At this time, the return spring 502 squeezes the extension plate 501, thereby moving the two positioning seats 2 away from each other, enabling the device to be used for newborns with different head circumferences, and allowing the heads of newborns to be effectively wrapped by the correction airbag 3. And by putting the flexible silicone head ring 605 on the forehead of the newborn, starting multiple micro-motors 601 to drive the winding drum 602 to wind up the elastic band 603, the traction frequency can be set to an intermittent mode or a continuous mode, and the traction direction is controlled by the cooperation of dual motors to achieve vector adjustment in three-dimensional space and accurately act on the skull deformity area, so as to intermittently traction the head of the newborn. The intermittent traction force can activate the osteoblast activity of the cranial suture and promote the local bone deposition rate increase. When the traction direction is aligned with the skull growth axis, it can guide the bone plate to expand along the direction of the least resistance, effectively correcting sagittal craniosynostosis or frontal bone asymmetry. The elastic traction band generates a gradual deformation when applying force, and the strain rate < 5% / s, avoiding skin ischemic necrosis caused by the rigid compression of traditional helmets. The contact layer of the flexible silicone head ring 605 is made of medical silicone, with an antibacterial silver ion coating on the surface, and the ventilation holes adopt a biomimetic honeycomb structure, and the air permeability reaches 3000g / m² / 24h, significantly reducing the incidence of eczema, thereby correcting the head shape of the newborn. Further, the user can drive the screw rod 701 to rotate by rotating the nut 702, thereby driving the positioning block 703 to move and adjusting the position of the first magnetic position sensor 704. The first magnetic position sensor 704 and the second magnetic position sensor 705 can detect the distance between each other through their own magnetic fields. When the newborn moves around and causes the first magnetic position sensor 704 and the second magnetic position sensor 705 to move away, the device issues an alarm to prompt the parent that the position has shifted, and reminds the parent to correct the position of the newborn to avoid the phenomenon that the position of the newborn moves around and causes the correction efficiency to decrease. In view of the high flexibility characteristics of the skull of premature infants, the device can be set to a low-force mode of 0.05~0.1N, and cooperate with the NICU monitoring system to prevent postural deformities. And when the device is produced, a respiration monitoring module can be set inside the flexible silicone head ring 605, including a fiber Bragg grating sensor: the fiber grid implanted in the pillow pad, with a spacing of 5mm, detects the chest undulation through the wavelength shift Δλ≈1pm corresponding to a displacement of 0.1mm, and cooperates with a microphone array combined with a voiceprint recognition algorithm to distinguish normal breathing from abnormal wheezing, further protecting the safety of the newborn during head shape correction.
