[0047] This embodiment provides a multifunctional intelligent nursing bed control system for geriatric neurology, including a pressure monitoring module, a humidity monitoring module, a body temperature monitoring module and an environment monitoring module. The specific implementation method is as follows:

[0048] Implementation of the pressure monitoring module: The pressure sensors 12 are evenly distributed on the surface of the mattress 15, and are used to collect pressure data of different parts of the patient's body in real time. The pressure distribution uniformity index U is calculated by the algorithm built into the control system.

[0049] For example, the system collects pressure data of 10 detection points as P = 10, 12, 11, 9, 10, 12, 11, 10, 9, 11] (unit: kPa), and the average pressure According to the formula:

[0050]

[0051] The system calculates U = 0.0476. When U exceeds a set threshold (eg, 0.05), the system issues an alarm through the display screen 25 to remind the nursing staff to check the patient's bed posture and adjust the pressure distribution.

[0052] Implementation of humidity monitoring module: The humidity sensor 13 is arranged on the surface of the mattress to monitor the humidity level around the patient in real time.

[0053] Assuming that the current humidity value rises from 60% to 85% within 5 minutes, the system calculates the humidity change rate R by the formula:

[0054]

[0055] If R>4% / minute (system preset threshold), the system triggers a humidity alarm and reminds the nursing staff through the display screen 25 to check whether the patient has excrement leakage or other fluid overflow to prevent infection risks.

[0056] Implementation of the body temperature monitoring module: A non-contact infrared body temperature sensor 22 is installed at the top rod 21 on the top of the bed 11 to collect the patient's body temperature data in real time.

[0057] Assuming that the body temperature rises from 36.5°C to 38.0°C within 10 minutes, the system calculates the body temperature change rate using the following formula:

[0058]

[0059] If T rate If the temperature exceeds the system threshold (e.g. 0.1°C / min), the system will issue an abnormal temperature alarm and upload the relevant data to the system log for reference by medical staff.

[0060] Implementation of environmental monitoring module:

[0061]

[0062] The environmental sensor 26 is mounted on the mounting plate 24 and is used to monitor the temperature and humidity data in the ward.

[0063] Assuming the ambient temperature is 75°F (Fahrenheit) and the relative humidity is 70%, the system calculates the comfort index CI by the following formula: If the comfort index CI exceeds the preset range (e.g. 70-76), the control system prompts the nursing staff through the display screen 25 to adjust the air conditioner or humidifier in the ward to optimize the patient's comfort.
