Description

Technical Field

[0001] The invention belongs to the technical field of neonatal care, and in particular relates to a head deviation prevention device for neonatal care. Background Art

[0002] The head bones of a newborn are relatively soft and the neck muscles are not fully developed. A bad sleeping posture of the newborn will directly affect the shape of the newborn's head. In order to allow the newborn's head to develop well, it is necessary to use anti-head tilt equipment to adjust the sleeping posture of the newborn's head to prevent the newborn's head from tilting.

[0003] Publication number: CN117338544A, discloses: a head deviation prevention device for neonatal care, which restricts the neonatal head by setting two head air cushions. If the head air cushion deviates and squeezes one of the head air cushions, the head air cushion will be compressed so that the gas squeezes the sliding plate. When the sliding plate moves to squeeze the pressure sensor, the user communication device will issue an alarm, thereby reminding the user to adjust the position of the neonatal head in time. At the same time, the side protection airbags are squeezed by the neonatal body, and the side protection airbags will be compressed. The compressed gas of the side protection airbags will enter the connecting pipe, and the air pressure drives the annular plate to move downward. When the annular plate moves downward and contacts the pressing rod, it will drive the pressing rod to move downward. The downward movement of the pressing rod will drive the driving rod and the guide rod to move downward. The downward movement of the guide rod drives the connecting cap and the threaded rod to move downward. The fourth spring is compressed, and the threaded rod rotates while moving downward. The rotation of the threaded rod will drive the toy attraction part to rotate through the rotating part. The toy attraction part can attract the attention of the neonatal when it rotates.

[0004] The above-mentioned prior art still has the following shortcomings during the specific implementation process:

[0005] During use, when the newborn's head shifts, an alarm needs to be issued to remind the user to adjust the position of the newborn's head. Adaptive adjustment cannot be achieved, and the anti-head deviation effect is poor. At the same time, only when the newborn's body is squeezed into the side protection airbag, the buffer mechanism and the drive component work together to trigger the attraction mechanism to attract the newborn's attention. If the newborn's head only shifts, the attraction mechanism cannot be triggered to achieve the purpose of attracting the newborn's attention, and the use effect is poor.

[0006] To this end, we designed a head tilt prevention device for neonatal care to solve the above problems. Summary of the Invention

[0042] A movable ring 27 is movably embedded between the two fixed rods 24. An annular groove 28 with a T-shaped cross-section is provided on the upper and lower surfaces of the movable ring 27. An arc-shaped clamping block 29 with a T-shaped cross-section is fixed to the end of the two fixed rods 24 that are close to each other. The arc-shaped clamping block 29 is movably matched with the annular groove 28 on the movable ring 27. A plurality of tooth grooves 31 are provided on the outer side of the movable ring 27. A motor 32 is installed on the top of the inner side of the cover 25. A gear 30 is installed on the output shaft of the motor 32. The gear 30 is engaged with the tooth groove 31.

A toy attraction 35 is fixed to the side of the connecting plate 34 facing the head latex pad 6 through a connecting rope. The shapes and styles of the plurality of toy attractions 35 are different.

[0043] A controller 36 is mounted on the outer wall of the upper fixing rod 24 . The first pressure sensor 11 , the second pressure sensor 14 , the cylinder 20 , the display screen 26 and the motor 32 are all electrically connected to the controller 36 .

[0044] Example:

[0045] During use, the head tilt prevention device for neonatal care is first placed on a flat surface, with the bottom of the support frame 1 supported on the flat surface, and then the body of the neonate is placed on the first protective pad 2, and the head is placed on the head latex pad 6;

[0046] When the newborn baby's head rotates and deviates, it squeezes the support plate 7 in the corresponding direction. Under the action of the rotating shaft between the support plate 7 and the vertical plate 5, combined with the sliding cooperation between the arc rod 9 and the fixing frame 8, the corresponding arc rod 9 is driven to move toward the inside of the fixing frame 8, and the first spring 12 is stretched until the disk 10 at the lower end of the arc rod 9 contacts the first pressure sensor 11 at the corresponding position. At this time, the first pressure sensor 11 is squeezed and transmits the squeeze signal to the controller 36.

[0047] The display screen 26 is activated by the controller 36 to play an animation video to attract the attention of the newborn baby, or the motor 32 is activated by the controller 36 to drive the gear 30 to rotate. Under the meshing action of the gear 30 and the tooth groove 31, combined with the sliding cooperation between the arc-shaped block 29 and the annular groove 28, the movable ring 27 is driven to rotate. Under the joint action of the connecting rod 33 and the connecting plate 34, the toy attraction member 35 is driven to rotate to attract the attention of the newborn baby.

[0048] At the same time, the cylinder 20 at the corresponding position is started by the controller 36, and the cylinder 20 is extended to push the push plate 21 downward, and the gas inside the fixed shell 19 is squeezed into the active cavity inside the arc block 15 through the connecting pipe 22. As the gas entering the active cavity inside the arc block 15 increases, the movable plate 16 is squeezed upward and the second spring 23 is stretched. As the movable plate 16 moves, the corresponding squeezing rod 17 is driven to move toward the outside of the active cavity, and then the corresponding squeezing roller 18 is driven to move toward the direction close to the support plate 7 until the squeezing roller 18 contacts the support plate 7 and slowly pushes the squeezed support plate 7 to the initial position until The support plate 7 returns to its initial position, achieving adaptive adjustment of the newborn baby's head. This solves the problem of the prior art that when the newborn's head deviates during use, an alarm needs to be issued to remind the user to adjust the position of the newborn's head, which makes adaptive adjustment impossible and the head deviation prevention effect poor. At the same time, it solves the problem of the prior art that, during specific implementation, the attraction mechanism can only be triggered to attract the newborn's attention when the newborn's body is squeezed against the side protection airbag in combination with the buffer mechanism and the drive assembly. If the newborn's head is only deviated, the attraction mechanism cannot be triggered to achieve the purpose of attracting the newborn's attention, resulting in poor use effect.

[0049] Among them, under the elastic action of the first spring 12, as the support plate 7 moves to the initial position, the arc rod 9 is driven to move synchronously to the position of the initial state. When the support plate 7 returns to the initial position, under the action of the arc rod 9, combined with the limit ring 13, the corresponding second pressure sensor 14 is driven to contact the inner wall of the fixed frame 8. The second pressure sensor 14 receives a pressure signal and transmits the pressure signal to the controller 36, judging that the support plate 7 has returned to the initial state, that is, the adaptive adjustment is completed. The extended cylinder 20 is driven by the controller 36 to retract, driving the push plate 21 to return to the uppermost side, and under the elastic action of the second spring 23, combined with the movable plate 16 and the extrusion rod 17, the extrusion roller 18 is driven to return to the initial position, which is convenient for subsequent adjustment and use.

[0050] It should be further explained that the installation structure, connection method or setting method of each component in the present invention are all common mechanical methods, and they can be implemented as long as they can achieve their beneficial effects. At the same time, the first pressure sensor 11, the second pressure sensor 14, the cylinder 20, the display screen 26, the motor 32 and the controller 36 in the present invention are all purchased on the market, and those skilled in the art can install and use them as required.
