System
Developed at the Thoraxcentrum of the Medical Faculty of Erasmus IJniversity, Rotterdam, the new OM -series Intensive Care Patient Monitoring System from Oxford Medical Systems will be on show for the first time at the IJK Hospital Physicists Association in Sheffield on April 18th, 1979.
Radiometer’s Qualichecks is a new, ready-to-usequality control system for all blood-gas analyzers. The system includes three levels of control liquid for pH, pCO., and PO,, a unique dispenser to ensure correct and anaerobic transfer of the liquid to the analyzer, a logbook for a full year’s plotting of measured values along with a ‘ITsers Handbook’.
It is claimed that the new system overcomes the widely-recognised problem that the proliferation of monitoring instrumentation around the beds of critically ill or post-operative patients was obscuring the importance of human observation - and in fact reducing personal contact of hospital staff with the patient. The multi-discipline team assembled by Erasmus University to design the new system decided that a modular design was needed which allowed all necessary monitoring and processing functions to be handled by a single unit alongside thepatient without taking up an excessive amount of bedside space. At the same time, the operation of the unit should be so simple that medical and nursing staff would be free to concentrate on the patient and his or her treatment. The single bedside monitor and analysis unit displays a wide range of physiological signals, is linked to electrodes, transducers, miniature thermisters and catheters to show ECG’s, blood pressure, central and peripheral temperatures, respiration and cardiac output determined by the thermodilution method.
The system offers significant advantages over other blood gas control products. The dispenser for anaerobic transfer assures greater consistency, reliability and confidence in sample injection. It greatly reduces dissimilarities of inter-personnel techniques. As all control products are affected by room temperature, a copyrighted template is provided to eliminate errors caused by varying room temperature and/or the water bath. Qualicheck2not only tells whether or not the analyzer is functioning well but also affords a complete evaluation of the analysers condition, giving fair warning when maintenance is required and spotting service problems before serious faults occur. Qualicheck@can be used with any blood-gas analyzer, and the amount of check solution in the glass ampoules is sufficient for both flushing and measurement.

553: Dual site EMC for
neuro-muscular
re-education
Cyborg Corporation has introduced the 553 Dual EMG - a portable biofeedback instrument which can monitor two muscle sites simultaneously. Designed specifically for neuro-muscular reeducation, the duel site 553 is particularly useful where cocontractions, substitution patterns, or opponens spasticity make single site feedback ineffective. The 553 shows the patient’s EMG activity from one or two muscle sites, on an easy-to-read display of LED’s which can be presented as single or dual channel absolute EMG or as a ratio of the EMG activity from the two sites. The unit also features two audio feedback modes, a calibrated threshold control for setting precise training goals, and an automatic battery check. Three ranges, encompassing 0.5 to 1000 microvolts, make this unit suitable for a wide variety of muscle re-education and relaxation applications.

Being modular, the Oxford OM-2 system allows all units, modules and transducers to be interchanged between beds. They can also be linked to a central nursing station. Oxford Medical Systems Limited Nuffield Way Abingdon Oxon OX14 1BZ
