Description

Technical Field

[0001] The utility model relates to the technical field related to medical devices, and in particular to a device for assisting hearing detection of newborns. Background Art

[0002] Newborn hearing screening is an examination method designed to detect whether the hearing function of newborns is normal. It evaluates the auditory response of newborns to detect and diagnose possible hearing problems as early as possible and provide support for children's language and cognitive development. Newborn hearing screening is usually performed a few days to weeks after the baby is born. This screening test is safe, painless and non-invasive. Common testing methods include automatic hearing screening devices or brainstem auditory evoked potential (ABR) testing. The automatic hearing screening device plays a series of sound stimuli and then detects the baby's auditory response. The ABR test assesses hearing by placing electrodes on the baby's scalp and recording the baby's auditory nerve's response to sound stimuli.

[0003] At present, in order to facilitate the examination, medical staff need to manually turn the newborn baby sideways during the hearing screening of newborn babies, so that the newborn baby's head is tilted to one side to wear the newborn hearing screening device. Medical staff need to operate the newborn hearing screening device by hand, and also need to hold the newborn baby to keep the newborn baby's head tilted to the side, which is inconvenient and difficult for one person to operate alone. In addition, when keeping the newborn baby's head tilted to the side, the newborn baby's body needs to be turned sideways to a certain extent to avoid twisting the newborn baby's neck, causing discomfort to the newborn baby, or even causing injury.
