Wireless Sensor Networking for Medical Monitoring

The MeshScape wireless sensor networking platform is flexible and robust enough to meet a broad spectrum of application requirements. It has enabled wireless sensor networking to be embedded in number of medical monitoring applications:
  • Health prevention
  • Home care
  • Elderly care
  • Disease management
  • Clinical trials  

 Unwiring for Improved Patient Monitoring
A leading global manufacturer of automation solutions. 

The healthcare market is a new strategic focus for this company. Their vision was to develop a new generation of medical devices to enable medical devices such as blood pressure monitors, blood glucose meters, thermometers, and body fat scales to transmit data wirelessly to a handheld device, such as a PDA.

The The MeshScape system provides an on-demand data model that supports highly mobile nodes in the network where a gateway device enters the network, automatically binds to that network and gathers data, then leaves the network. With this model, one mobile gateway can bind to multiple networks and multiple mobile gateways can bind to a given network. This is exactly the data model this company needed to develop its next-generation medical monitoring system. With this system, patients in a hospital wear sensors to monitor the various vital signs and doctors access that data via a PDA that is a mobile gateway or a PC via a USB gateway. A doctor enters a room and the mobile PDA automatically binds with the network associated with that patient and downloads vital sensor data. When the doctor enters a second patient’s room, the PDA automatically binds with that network and downloads the second patient’s data.

The benefits of wireless monitoring applications are multifold. Patients’ comfort is improved by removing the encumbrance of wires. Patients can also be continuously monitored even while ambulatory. Medical personnel can retrieve vital signs and other medical data quickly and in real time, enabling them to monitor more patients without reducing quality of care. Patients can be monitored remotely enabling patient care to extend to the home. And since recording of the medical data is automatic, human error is minimized.
