Medical Equipment Shipment

DataNet System Monitors Medical Equipment Shipment Conditions for
Medtronic, Singapore
For 40 years Medtronic have been pioneering medical technologies that save and extend thousands of lives and relieve suffering of patients all over the world. In the production of medical equipment for surgical procedures, Medtronic must carefully monitor the incubator storage and global shipment conditions and ensure a constant temperature is maintained in transport between countries. The application has a particular challenge in that the incubator walls are made of metal, the DataNet system was able to overcome this particular challenge by leveraging the new SRR mode. An additional DataNet is placed inside the incubator's room and is set to SRR mode. The unit measures room temperature and communicates with the additional DataNet units inside the incubators, By applying the SRR short range repeater for DNL910 and DNL920, the technicians are able to overcome any RF barriers. Data loggers in SRR mode must be connected to AC at all times, as with all DNR900 units. The SRR units can connect to 24 data loggers and 16 Repeaters (Repeaters can be DNR900, DNL920 & DNL910 in SRR mode). The Medtronic application loggers now also operate as ZigBee repeaters for short range (SRR) which reduce costs and increase network robustness. So far the initial implementation has proved very successful, the company have found the units to improve efficiency and reliability of procedures and they plan to extend the system with more units in the short term.

Malaysian Hospital Uses Wireless System to Overcome Microbial Infestation Obstacles

A recent application for the Government of Malaysia's Ministry of Health was to provide a solution for a leading hospital that faced a severe problem of microbial infestation. The situation had deteriorated to such an extent that the entire 10 storey 1 million sq ft building had been forced to shut down.

As part of government's inquiry into the source of the problem the fourtec wireless system was installed. Data loggers were placed at various locations throughout the hospital's wards to determine the humidity in the supplied air, returned air, fresh air and the occupied spaces. The aim being to establish at what point the humidity spike occurs, since this enabled the microbial infestation to proliferate. The humidity activity was monitored over a period of a week to ensure that it did not exceed 75%.

The hospital covers a large area and so the solution chosen had to provide a single system that could monitor the entire zone, until a clear humidity trend could be identified and so the problem diagnosed. The system had to be reliable since the readings of the data loggers were essential in determining the high humidity areas, before treatment to resolve the issue could begin.
