In addition, when any of the pressure sensitive test areas 200b, 200c, 200d, 200e, and 200f detects pressure, the control terminal (50) determines, based on the patient status signal, that the patient is about to fall under the bed or In order to get out of bed, a warning signal is sent to the alarm device, and the patient information is displayed on the LED board of the nursing station; at this time, the alarm device displays a warning message and a beep, indicating that the patient is currently in a dangerous state, nursing After receiving the message, the staff can go to the ward for treatment. Similarly, when the pressure sensitive test area is 200b and 200d, the pressure sensitive test area 200c and 200e, the pressure sensitive test area 200d and 200f, or the pressure sensitive test area 200e and 200f are simultaneously detected. When it comes to stress, it also means that the patient is in danger.

Further, when the caregiver receives the message that the patient is in a dangerous state, if not processed in time, the monitoring alert calling device (50) will send a corresponding warning message to the nursing device holding the alarm device (60) at intervals. Personnel, until the caregiver arrives at the scene for processing, and presses the warning release button disposed on the ward call device, and after completing the action of canceling the warning, the message is returned to the monitoring alert calling device (50), and the monitoring call device is monitored. ) Stop sending a warning message and record the warning release time.

To further illustrate, in order to facilitate the need for a small number of caregivers to care for the majority of patients at the same time, and the caregiver may be on the road or not staying at a fixed point for a long time, etc., the situation that often occurs is extremely low in power consumption in this creation. ZigBee wireless transmission technology will enable the alarm device (60) to be designed as a compact portable device, so that the nursing staff can keep abreast of the patient's condition, go to the inspection immediately, or provide appropriate assistance at the right time.

Moreover, when the nursing staff is responsible for a large area of care, a patient condition signal for receiving the sensing from each of the plurality of beds (10) may be additionally provided, and the signal is received. And then transmitted to one of the alarm devices (60), a relay transceiver (not shown), of course, each of the alarm devices (60) can also be configured to have the function of transmitting and receiving signals, so that each The alarm device (60) also serves as a relay transceiver for other alarm devices (60), thereby expanding the effective application range of the device and avoiding the occurrence of important signal leakage.
