摘要:

This paper was originally commissioned by the UK Department of Health as a contribution to the work of its Biomaterials and Implants Research Advisory Group. This group was set up under the Chairmanship of Professor Sir Colin Berry with the following terms of reference: (i) to identify recent advances in the field of biomaterials; (ii) to consider the future contribution of biomaterials in improving human health; (Hi) to advise the Standing Group on Health Technology in areas where developments and assessment are needed; and (iv) to report to the Director of Research and Development (Professor Sir Michael Peckham) by October 1995. The cardiovascular field was one of several areas in biomaterials/implants considered by the Advisory Group. Amongst other areas considered were orthopaedics, dentistry, urology, wound repair and ophthalmology. Additionally, consideration was also given to such topics as chemical and biochemical sensors, drug release, hydrogels, membranes and artificial organs. The final report of the Advisory Group will be published at the end of this year. However, the Department has agreed that individual working papers such as the present one can be published independently in appropriate scientific journals.

摘要:

Ensemble signal averaging is conventionally used to reduce the noise content o/ECG recordings. One shortcoming of this technique is that it removes the possibility of registering transient signals. As a consequence the simultaneous averaging of spatially related leads has been used. This relies on the recording electrodes receiving correlated signal components for reinforcement together with uncorrelated noise. We have developed a methodology for studying EMG noise reduction by spatial averaging and present results for different electrode spacings which suggest minimum separations for noise rejection.

摘要:

Most of the automated non-invasive blood pressure (NIBP) monitors in clinical use rely on the oscillometric technique for measuring the blood pressures. The functional evaluation of these monitors has relied on comparison with intra-arterial blood pressure measurements or comparison with‘standard’non-invasive blood pressure meters such as the Hawksley random zero sphygmomanometer. The commercial availability of simulated arm test instruments provides the opportunity for developing an alternative evaluation method. We describe the control of an NIBP simulator by a personal computer which is also linked to the NIBP monitor under test. An evaluation protocol is described and the data analysed to present graphically and in tabular form an assessment of the NIBP monitor.
