Detailed Description

Referring to fig. 2, the multifunctional sleep nursing and monitoring device based on Zigbee (Zigbee) of the present invention includes one or more PDAs or mobile phones supporting Zigbee protocols, one or more sleep monitoring nodes; PDA or mobile phone devices and between the PDA or mobile phone devices and the sleep monitoring node are communicated through Zigbee/802.15.4, and the effective communication range is about 100 meters. The PDA or the mobile phone device communicates with the remote monitoring center through a telecommunication network or the Internet.

Any existing monitoring equipment supporting the Zigbee protocol can be conveniently added into a network formed by the multifunctional sleep nursing and monitoring device. Meanwhile, each measuring electrode and each probe can be plugged and pulled at any time, so that various monitoring requirements can be met conveniently. The invention can be properly adjusted according to different use purposes, and has certain flexibility. For example, in the case of monitoring a baby, the sensor electrodes or probes can be placed centrally on the foot; for monitoring general patients, the monitoring device can be intensively placed at the hand part; for long-term patients or patients with serious diseases, the device can be respectively placed on the chest and the hands. The hardware configuration in the above example is substantially the same, except that the required ECG leads may be different.

According to different conditions and monitoring purposes of sleepers, the device disclosed by the invention divides sleep monitoring into two modes: one is a home monitoring mode and the other is a remote monitoring mode. The home mode is mainly suitable for monitoring babies, children or general users, monitoring data and pictures are mainly displayed through a PDA or a mobile phone, the remote monitoring mode is mainly aimed at patients, and the mode needs professional observation and is generally executed by professional medical care personnel in hospitals.

The invention provides a reminding or alarming service for the condition which can occur in the monitoring or monitoring. The threshold for achieving a reminder or alarm condition may be set by software. The alarm modes in the household monitoring mode include sound alarm, automatic dialing alarm, light flashing alarm and the like of a PDA or a mobile phone; in the remote monitoring mode, besides the above mode, a more professional alarm mode can be determined by the remote monitoring center so as to be convenient for timely processing.
