Embodiment 1

[0024] Such as figure 1 The ZigBee-based ward wireless monitoring system shown includes a variety of physiological parameter miniaturized modules with built-in ZigBee modules, monitoring base stations including ZigBee modules, and nurse central servers. The physiological parameter miniaturized modules are wirelessly connected to the monitoring base station through ZigBee. Nurses are connected to the central server. A three-layer management structure is adopted, that is, one nurse central server manages multiple monitoring base stations, and each monitoring base station manages multiple miniaturized modules of different types of physiological parameters. The types of physiological parameter miniaturized modules include ECG module, blood oxygen module, breathing module, heart sound module, and body temperature module.

[0025] Each physiological parameter miniaturization module includes a signal preprocessing circuit and a wireless radio frequency circuit, and the wireless radi...

Embodiment 2

[0049] In order to further expand the mobile area of ​​the user in the ward wireless monitoring network system, such as Figure 6 The system uses a tree topology to build a full wireless network in the ward. According to three core stack parameters (stack depth MaxDepth=5, the maximum number of child nodes MaxChildren=17, and the maximum number of routes MaxRoutersPerParent=4), a three-layer tree topology structure is constructed, and a traditional four-layer architecture is adopted. The ZigBee network coordinator builds the network and if the management entity finds a suitable channel, it selects a PAN identifier for the new network. After the network is successfully established, the ZigBee router can be directly connected to the network through the pre-allocated parent device. If the ZigBee router is successfully connected to the network, each wireless physiological parameter miniaturized module can be started to enter the network and start working, and communicate with the...

Abstract

The invention discloses a ward wireless monitoring system based on ZigBee and consists of a plurality of wireless physiological parameter miniaturization modules, a monitoring base station and a nurse central server. The invention also discloses the application of the ward wireless monitoring system based on ZigBee to ward centralized wireless monitoring and patient random movement monitoring. The ward wireless monitoring system can collect a variety of physiological parameters such as electrocardiosignals, heart rate, heart sound, oxygen saturation of blood, body temperature, and the like, and adopt ZigBee technology for wireless transmission of data so as to realize ward centralized wireless monitoring and patient random movement monitoring and facilitate the medical staff monitoring the disease process of patients and taking protection measures. The system of the invention has the advantages of low power consumption, miniaturization, low cost, convenient network formation, capability of detecting a variety of parameters, good extending and interactive ability and high reliability; the system can reflect the physiological status of the body more veritably and can greatly reduce the electric cable connection on critical patients, thus facilitating the wearing of patients as well as the diagnosis and treatment operation of doctors and nurses.

Description

technical field [0001] The invention belongs to the field of medical electronic equipment, in particular to a ZigBee-based wireless monitoring system for a ward that detects, transmits, stores, and monitors various physiological parameters of a human body. Background technique [0002] At present, the traditional monitoring system using wired connection is often bulky and power-consuming, can only be used in a specific area, lacks flexibility, and limits the movement of patients and medical staff; and it is easy to cause discomfort to patients, especially those that require long-term monitoring Patients, it is difficult to realize real-time monitoring of patients' real physiological conditions, which affects the accuracy of detection data. The wireless technology can change the traditional wired monitoring method and provide patients with comfortable and continuous monitoring services of vital sign parameters. It can make the equipment in the medical monitoring system of th...
