摘要:

Hydrophilic graft copolymers are derived from hydrophobic polymers which have been copolymerized and then grafted by radiation initiation so that they become hydrophilic. Tubes of such material expand in diameter by 60% when wet and become slippery. The first medical application of these materials are described: they have been used as an access conduit for percutaneous renal surgery and endoscopic access to the ureter.

摘要:

A large international co-operative project, sponsored by the European Commission, was launched in 1980 aimed at developing common standards for quantitative electrocardiography. The jrst and main objective of the project was to reduce the wide variation in wave measurements currently obtained by electrocardiographic computer programs. To this end a reference library was developed and a comprehensive reviewing scheme was devised for the visual determination of the onsets and offsets of P, QRS and T. This task was performed by a board of cardiologists on highly amplijed recordings, in an interactive four round Delphi-type analysis. The reference library, so obtained, has become an internationally recognized yardstick for the evaluation and improvement of ECG measurement programs. It has been used to test the performance of 9 VCG and 10 standard 12-lead programs. The library proved to be a weful instrument in the establishment of recommendations for more precise measurement rules and dejnitions. Records with added noise and multi-lead ECGs were subsequentlyy analysed to meet specafc objectives. The project was expanded in 1984 towards testing and improvement of diagnostic criteria and classification programs.

摘要:

Equipment management arrangements in hospitals, including safety and function testing, relating to continuous-flow anaesthetic apparatus have been found wanting following examination of a number of recent incidents. A problem exists with the complexity of the tests required and the number of necessary test instruments. In this article the required tests are examined, and a specially designed test set to make fuller testing a practical proposition for hospital staff and for manufacturers' service technicians is described.

摘要:

There is a growing interest in the potential benefits to be obtained from closed-loop control of drug infusion [1—5]. The most widely available infusion pump which is specifically designed for control by computer is the 929 volumetric infusion pump produced by Imed. The increasing availability of microcomputers suggests that they will be used more frequently to control such pumps. However, difficulties can arise when the attempt is made to establish communication between the computer and the pump [6]and a method employed for this purpose is described in this article. The aim was to provide a simple method of conducting the required communication between the computer and the pump using a high—level language. The commands specified in the high—level Language are passed to a machine—code subroutine which organizes transmission to and receives data from the pump.

摘要:

‘Health Equipment Information’No. 138, published in March 1985 contains evaluation reports on 12 pneumatic tourniquet controllers. The Conn, Hoyles OEC 855 and 960, the Richards Constant Aire, the Schuco AT 401 and the Stille are single cuff models, while the Anetic Aid APT, the Braun SC2, the Holborn SCT2, the Oxylitre 551 and the Thakray A100 are double cuff models. The DHSS understand that the Hoyles Tourniquet and the OED 960 are no longer manufactured, the results are included for purposes of comparison.For full details of the evaluation findings readers should consult HEI 138-the following contains extracts from the report.

摘要:

The 20th Annual Meeting of AAMI (Association for the Advancement of Medical Instrumentation) was held from 1 to 8 May this year at the Boston Marriott (Copley Place) Hotel. The conference's theme‘Transitions in Health—Care Delivery’was chosen to emphasize the changes in health—care over the last 20 years. The meeting's co—chairmen, Drs Michael Neuman (Case Western Reserve University) and John Pearce (University of Texas at Austin) assembled a scientific programme with papers on such new techniques as diagnostic imaging without film and applications of process control to infusion technology; new approaches in such clinical areas as cardiovascular diseases and perinatal medicine, and new experiences in clinical engineering and management.
