Abstract

The invention provides a patient monitor having entertainment functions and a control method thereof. If a user initiates the entertainment functions of the patient monitor having entertainment functions, a system thereof sends an entertainment signal to an entertainment signal processing unit, the entertainment signal is then processed to display an image on an entertainment specific display apparatus, and sound playing is achieved via an entertainment specific loudspeaker; the system sends a parameter signal to a parameter signal processing unit in real time, the parameter signal is then processed to display real-time measurement values and waveforms of parameters on a monitor specific display apparatus, and playing of various sounds is achieved via a monitor specific loudspeaker; an alarm processing unit detects, in real-time, whether the physiological characteristics of patient meet the alarm condition, and once the condition is met, alarm is triggered immediately; with the patient monitor of the invention, patients can enjoy some entertainment activities for mental relaxation while lying on the bed without having an impact on normal real-time monitor for patients.
