Embodiment Construction

[0041] like Figure 1~6 As shown, the outdoor wireless monitoring system for hospital patients is connected to the dual-mode wireless transmission system by the upper computer through Ethernet and GPRS network; the dual-mode wireless transmission system is connected to the ZigBee wireless sensor network through the RS232 serial port. The internal connection relationship of the dual-mode wireless transmission system is: the power supply voltage conversion module is connected with the WLAN module and the GPRS DTU module. The ZigBee wireless sensor network consists of three parts: coordinator node, reference node, patient positioning and physiological parameter collection node; the coordinator node, reference node, patient positioning and physiological parameter collection node are connected to each other through a 2.4GHz wireless network; the coordinator node is responsible for The establishment of ZigBee wireless sensor network and data forwarding between ZigBee wireless sensor...

Abstract

The invention discloses an outdoor wireless monitoring system of a patient in a hospital, consisting of three parts, namely a ZigBee wireless sensor network, a dual-mode wireless transmission system and an upper computer, wherein the ZigBee wireless sensor network comprises a coordinator node, a reference node and a patient positioning and physical parameter collecting node; the dual-mode wireless transmission system can carry out Ethernet transmission and GPRS network transmission; the software of the upper computer is divided into a head nurse station, a resident enrolled nurse station and a nurse duty station. The system collects the physical parameters of electrocardio, blood oxygen, blood pressure, pulse rate, body temperature and the like and outdoor position data of the patient in real time; a true-code and reverse-code calibration method is adopted when in wireless transmission; a fusion method of Manhattan difference value positioning and Location Engine positioning is adopted when in positioning; and the system has the functions of emergency alarm of patients, under-current alarm of batteries, threshold alarm of physical parameters and the like and ensures that the patients in outdoor activities obtain real-time and effective monitoring.

Description

technical field [0001] The invention relates to the technical field of medical monitoring, in particular to an outdoor wireless monitoring system for hospital patients and a patient positioning method thereof. Background technique [0002] The implementation of individual follow-up nursing monitoring for critically ill patients and patients with sudden risk began in the 1930s and 1940s abroad. At that time, it was completely dependent on the direct care of the nursing staff without any equipment. In the 1950s, due to the birth of the transistor, medical instruments were reduced in size and cost, and on-site monitoring instruments for vital sign parameters such as blood pressure, respiration, and body temperature began to appear. In this field, Germany's Siemens (SIEMEMS) has been in the leading position in technology for a long time. In the 1960s, Siemens took the lead in launching the first generation of wired remote medical monitors, which could monitor physiological par...
