The invention relates to the field of medical instruments, in particular to an intelligent nursing bed. The intelligent nursing bed comprises a bedstead, a bed board fixedly installed on the bedsteadand a detachable mattress installed on the bed board, wherein the mattress comprises a moving board and a nursing board, a nursing hole is formed in the nursing board, a defecation suction base is installed at the lower end of the nursing hole, and the intelligent nursing bed further comprises a nursing hole blind used for opening or closing the nursing hole, a driving device used for driving thenursing hole blind to move, a nursing device used for collecting urine and excrement, a first detecting device used for detecting whether or not a user defecates, a second detecting device used for detecting whether or not defecation of the user is completed, a cleaning device used for cleaning a defecation portion of the user, a control unit which receives a first detection signal of the first detecting device and a second detection signal of the second detecting device and controls the driving device, the nursing device and the cleaning device to work. By means of the intelligent nursing bed, the problem that due to the fact that an existing nursing bed cannot detect defecation of the user in time, the effect of treating urine and excrement of the user is poor can be solved.

The invention provides an ultrasound knife exciting device and an exciting method, and aims to solve the technical problems that a traditional ultrasound knife exciting device adopts more separation elements, electric signals among the elements have poor transmission accuracy, and separation elements have large performance drift after long-time using and cannot generate stable and high-performance sinusoidal signals or generate sinusoidal signals with stable frequency and uniform amplitude to excite the ultrasound knife. The device comprises a main processor, a main power supply, a fixed reference power supply, a user keyboard, an LCD display module, an FPGA unit, a digital-to-analogue conversion unit, an analogue-to-digital conversion unit I, an analogue-to-digital conversion unit II, an adjustable switch power supply, an adjustable reference power supply, a clock unit, an amplification circuit, a signal regulation circuit, a voltage monitor module, a current monitor module and a signal output end. The ultrasound knife exciting device and the exciting method can be widely applied to surgical operation devices.

The embodiment of the present application is applicable to the technical field of medical equipment, and provides a ventilator control method, device, and ventilator. The method includes: collecting the user's current physiological signal, and the physiological signal includes EEG signal and EMG signal. Identify the brain wave type corresponding to the EEG signal, determine the user's current sleep stage according to the EEG type, and the sleep stage includes the sleep stage, the micro-awakening stage or the awake stage; identify the EMG signal corresponding to According to the voltage value, the current physiological state of the user is determined according to the voltage value, and the physiological state includes a tense state or a relaxed state; according to the sleep stage and the physiological state, the working state of the ventilator is controlled. In this embodiment, the degree of muscle tension and sobriety can be judged in real time by collecting the user's physiological signals, and the work of the ventilator can be controlled more accurately according to different stages or states, and the effectiveness of the use of the ventilator can be improved.
