The invention discloses a wireless multi-bed electrocardio monitoring device which comprises a center monitoring end, an upper computer and n bed monitoring terminals. The bed monitoring terminals are connected with the center monitoring end through a wireless transmission module, the center monitoring end is connected with the upper computer, the upper computer is used for receiving electrocardio information sent by the center monitoring end and monitors whether the electrocardio information of the bed monitoring terminals is normal or not, and if not, a buzzer gives out an alarm signal automatically. According to the wireless multi-bed electrocardio monitoring device, the upper computer, the center monitoring end and the wireless communication module are arranged, the multiple bed monitoring terminals are controlled to acquire electrocardio signals of different patients on different beds, a doctor or a nurse can remotely read the electrocardio information of multiple different patients so that the illness states of the patients can be known timely, intelligent monitoring and managing of electrocardio data of multiple sickbeds are achieved, the intelligent degree is high, and operability is high; work intensity of medical staff is greatly lowered, and it is beneficial to popularization of the wireless multi-bed electrocardio monitoring device.
