Problems solved by technology

However, the above-mentioned monitoring devices all need to use contact devices such as electrodes or sensors to pick up respiratory signals, which will greatly restrain the baby during long-term monitoring, and easily block the baby's breathing passage.

Embodiment Construction

[0026] Such as figure 1 As shown, a wireless monitoring device for infant apnea, including a respiratory signal detection module that emits microwave signals to detect the infant's respiratory status, compares the detected respiratory signal and performs frequency conversion with the apnea detection module and compares it with the set threshold And trigger the sound and light alarm module of the alarm.

[0027] Among them, the respiratory signal detection module includes a microwave sensor. The microwave sensor directional transmits a microwave signal with a frequency of 24 GHz to the baby's chest wall, and receives the microwave signal reflected by the baby's chest wall, and outputs it to the signal amplifier. After the signal amplifier amplifies the breathing signal, it outputs it to the Apnea detection module. The microwave signal emitted by the microwave sensor directly irradiates or penetrates the clothes to irradiate the baby's chest wall. The micro-movement of the baby...

Abstract

The invention discloses a wireless monitoring device for infant apnea, which comprises a respiratory signal detection module for emitting microwave signals to detect infant respiratory conditions, an apnea detection module for comparing detected respiratory signals and converting frequency and a sound and light alarm module for comparing with a preset threshold and triggering an alarm. The wireless monitoring device for infant apnea wirelessly detects infant respiratory signals and then converts the signals to respiratory frequency signals and voltage signals. After the signals are compared with the preset threshold, when frequency is found to be too low so that apnea is caused, the alarm signals are triggered. By means of the sound and light alarm, guardians are informed and correct sleep positions of infants timely or do other treatments to ensure normal respiration of the infants.

Description

technical field [0001] The invention relates to a human breathing monitoring device, in particular to a device for monitoring infant apnea. Background technique [0002] Infant apnea refers to premature infants who stop breathing for more than 20 seconds, and full-term infants who stop breathing for more than 15 seconds. It is common in infants between 2 weeks and 1 year old during sleep. Apnea is a serious phenomenon, which is mainly caused by the baby's improper sleeping posture or poor breathing passage. If it is not treated in time, long-term hypoxia can cause brain damage and have a great impact on the baby's intellectual development. Can cause death in infants. [0003] For high-risk infants who are prone to apnea, clinical observation alone is often not enough, and monitoring with a monitor can detect apnea in time. At present, four-channel monitoring is usually used, that is, ECG, respiratory monitoring plus pulse oxygen saturation and thermal sensors under the ext...
