Abstract

The disclosure 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 disclosure, 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.

Claims

1. A patient monitor having entertainment functions, comprising:

a signal acquisition unit for acquiring external input signals, a signal reception unit for receiving the acquired signals, a master control unit for completing the assignment of the received signals, a particular signal processing unit for processing different assigned signals, a storage unit for selectively storing the information of the particular signal processing unit, and an audio and video output unit for outputting the particular signals;

the signal acquisition unit comprising an entertainment signal acquisition unit for acquiring an entertainment signal, and a physiological parameter signal acquisition unit for acquiring physiological characteristics of monitored patients;

wherein the particular signal processing unit comprises an entertainment signal processing unit for processing the signals acquired by the entertainment signal acquisition unit, a parameter signal processing unit for processing the information of the physiological parameters acquired by the physiological parameter signal acquisition unit, and an alarm signal processing unit for judgment according to the processing result of the parameter signal processing unit;

wherein the entertainment signal processing unit comprises an entertainment signal reception unit, an entertainment apparatus initiation unit and a signal judgment unit;

the entertainment signal data is received by the entertainment signal reception unit and is then differentiated by the signal judgment unit in order to determine whether the data is single audio signal data, or single video signal data or the data of both audio and video, and an apparatus initiating signal is input to the corresponding audio and video output unit according to the result of the signal judgment unit;

wherein the audio and video output unit comprises a monitor specific display apparatus and a monitor specific loudspeaker which are connected with a signal output end of the alarm signal processing unit, and an entertainment specific playing display apparatus and an entertainment specific loudspeaker which are connected with the entertainment apparatus initiation unit;
