Description

Multifunctional cradle

Technical Field

The utility model relates to a shaking bed or a cradle series, in particular to a shaking bed or a cradle for infants.

Background

Before the infant is born, the fetus is suspended in maternal placental amniotic fluid and grows and develops in a "wobble" as the mother moves. After birth, continuation of this rocking environment is a necessary measure to transition and adapt the child to the new environment. Researchers at state university of ohio have found that shaking seems to be a continuation of the infant's life in the placenta of the mother, and that light shaking stimulates the vestibule of the infant's inner ear, which is beneficial to the infant's development and growth. Therefore, after the baby is born, the mother (caregiver) is required to hold the baby and shake the baby. The advent of bassinets provides this condition for young children. Not only can create comfortable feeling for the infant to promote the sleep of the infant, but also the cradle is an effective tool for helping parents (or nursing personnel) to save labor time and improve working efficiency.

Domestic cradle has only two forms in history, one is rocking to the left and right of the infant, and the mode is proved by medicine to be unfavorable for the infant to develop and is not used for a long time. Another way is to hang the cradle on a rack at its four corners with ropes or straps and push it to swing, causing the cradle to swing back and forth in a "swing" fashion.

In summary, there are five major disadvantages to the cradle or rocking bed on the market today:

1. Not fit for the physiological science of infants and has weak comfortable feeling. Because the baby is affected by the centrifugal force of the center of gravity no matter how the baby swings, the body, mind and brain are pressed. When the cradle does not swing, the head and the feet are at the same height, and when the cradle swings, the head is lower than the body by half of the swing, and the baby always keeps in an overweight and weightless state due to the swing with centrifugal force; when the head is lower than the body, the brain of the infant grows and develops very badly.

2. The support occupies a large space, is inconvenient to move, can be used for a long time, and has safety risk when the cradle is hung up.

3. The function is single. Can only be used as a cradle and has no other purposes.

4. Saves labor, time and labor. One is that manual pushing is still required. Secondly, after the infant sleeps, once the nursing staff leaves the cradle, the sleeping condition of the infant cannot be monitored.

5, most of the cradle has a round bottom and is too soft, so that the protection and growth of the spine of the infant are not favorable for a long time of sleeping.
