Description

Technical Field

[0001] The present invention relates to the technical field of cardiology, and specifically to a recovery device for postoperative care in cardiology. Background Art

[0002] With the acceleration of the urbanization process, the amount of urban garbage generated increases year by year. The traditional manual garbage classification method is inefficient (daily processing volume < 2 tons / person), and relies on the experience of sorting personnel, with problems such as low classification accuracy (average about 65%) and high labor intensity. Existing automated sorting equipment is mostly based on infrared spectroscopy or mechanical screening technology, with defects such as high equipment cost (single set > 500,000 yuan) and complex maintenance.

[0096] The following is an introduction in conjunction with specific embodiments:

[0097] Embodiment 1:

[0098] The device startup process is as follows:

[0099] Hardware self-test:

[0100] The self-test unit scans the status of each module through the JTAG interface. If the SPI communication of the heart rate monitoring unit is abnormal, the "Sensor Calibration" prompt will be displayed on the touch screen;

[0101] The energy management module automatically switches to external power and distributes 70% of the power to the monitoring and control module.

[0102] Medical staff set patient information (age, medical history) through the interactive module, and the adaptive algorithm unit generates an initial rehabilitation strategy based on it (such as the initial value of the body position angle is 15°);

[0103] The environmental conditioning unit presets target parameters: temperature 22°C ± 1°C, humidity 50% ± 5%.

[0104] The communication module connects to the hospital HIS system via Wi-Fi, retrieves the patient's preoperative electrocardiogram data, and the storage unit establishes a personalized baseline model.

[0105] Example 2: Dynamic rehabilitation strategy adjustment

[0106] When the patient's blood oxygen saturation fluctuated on the third day after surgery (SpO2 dropped from 98% to 92%):

[0107] The data analysis unit identified the downward trend of SpO2, and the adaptive algorithm unit determined it to be moderate hypoxia (secondary abnormality);

[0108] The control module generates instructions: the frequency of pneumatic massage is increased to 45 times / minute, and the bed is adjusted to a head-high, feet-low position (20°).

[0109] Execution module response:

[0110] The pneumatic massage unit drives the air pump through a PWM signal, with an air pressure fluctuation range of 0.2-0.5MPa and lasts for 10 minutes;

[0111] The body position adjustment unit controls the electric push rod via the CAN bus and completes the angle adjustment within 5 seconds.

[0112] After 10 minutes, the blood oxygen saturation recovered to 95%, the control module adjusted the massage frequency back to 30 times / minute, and recorded a recovery report.

[0113] Example 3: Exception handling in complex environments

[0115] The energy management module seamlessly switches to battery power, giving priority to ensuring the operation of the monitoring and alarm modules;

[0116] The environmental monitoring unit detects PM2.5 concentration up to 200μg / m 3 , the control module triggers the secondary alarm, and the remote notification unit sends an early warning to the nurse station.

[0117] The environmental conditioning unit activates the backup battery-powered portable air purifier, reducing PM2.5 to 50μg / m within 30 minutes 3 ;
