Claims

1. A smart pressure-reducing mattress system based on multimodal blood perfusion monitoring, characterized in that, include: An array-type airbag layer includes wedge-shaped airbags arranged sequentially along the central axis of the bed length direction. The wedge-shaped airbags are in two groups, left and right, and are connected to the air cylinders through air tubes. The air tubes are equipped with solenoid valves. The multimodal sensor monitoring layer includes a pressure sensor, a temperature sensor, a subcutaneous humidity scanner, a laser Doppler probe, and an ultrasonic probe, all mounted on an array of airbag layers. The multimodal data fusion and clinical decision-making layer includes a multi-channel data acquisition module and a control module. The multi-channel data acquisition module acquires multimodal monitoring data uploaded by the multimodal sensor monitoring layer. The control module performs data fusion processing based on the multimodal monitoring data and establishes an early warning model. Based on the prediction results of the early warning model, the control module issues a risk warning signal and controls the solenoid valve of the array-type airbag layer to perform inflation and deflation operations.

2. The intelligent pressure-reducing mattress system based on multimodal blood perfusion monitoring as described in claim 1, characterized in that, Each set of wedge-shaped airbags can be inflated and deflated simultaneously. With the control of the solenoid valve, both airbags can be deflated at the same time, one side can be significantly inflated, the other side can be deflated, and local inflation and deflation can be achieved to change the pressure of different body parts and assist patients in changing body positions.

3. The intelligent pressure-reducing mattress system based on multimodal blood perfusion monitoring as described in claim 2, characterized in that, The pressure sensor, made of flexible material, is installed on each wedge-shaped airbag to collect local pressure changes at the pressure point in real time. The temperature sensor is evenly distributed on the wedge-shaped airbags according to the human head, chest, abdomen, and limbs, and collects temperature data periodically. The subcutaneous humidity sensor is covered on each wedge-shaped airbag in a grid pattern and periodically scans the subcutaneous humidity to analyze skin texture and edema. The laser Doppler probe is fixed to the surface of the airbag by a flexible bracket to detect key areas of blood circulation.
