摘要:

A review of noninvasive techniques for the evaluation of peripheral and cerebral circulation is given. The various methods are discussed in the context of the role of the Clinical Engineer in the Vascular Laboratory. The methods employed clinically and two of the most promising techniques being developed at the Medical College of Wisconsin, nuclear magnetic resonance (NMR) and transcutaneous electromagnetic flowmetry (TEMF), are described.

摘要:

An evaluation of strain gauge and LVDT pressure transducers was performed in an attempt to isolate some easily detectable parameter which might foretell the condition of the unit before each use. An analysis of STATHAM-GOULD P23Db strain gauge and HEWLETT PACKARD 1280C LVDT pressure transducers indicated a relationship between zero offset and major changes in calibration factor (sensitivity). The number of units with major changes in calibration factor increased as the offset exceed one hundred millimeters of mercury. A simple and practical method of checking zero offset is indicated.

摘要:

The escalating cost of energy is of concern to the hospital industry, and this cost has led to increasing interest by hospital administrators in energy conservation programs as part of their cost-containment efforts. An effective and comprehensive program should be based on an energy management approach which includes the careful analysis of the activities of the entire hospital staff. The clinical engineer has significant opportunities to contribute to this effort through his own department's activities and in other areas where his engineering training can be effectively utilized.

摘要:

The Clinical Engineering Center of the Northern New England/University of New Hampshire has developed a seminar on electrical safety for members of the nursing profession. This program provides an understanding of basic circuit theory, grounding problems, wiring systems, and electrical safety. Examples are drawn from actual clinical situations. Portions of the seminar are devoted to equipment demonstrations and to a panel discussion which provides the participants with an opportunity to ask questions. Through this experience, the nurses begin to view the function of a Clinical Engineer in a different light, their awareness of the role of the Clinical Engineering Center is expanded, and they become a second line of defense for electrical safety in the hospital.

摘要:

Biomedical equipment maintenance and repair activities involve an increasing amount of paperwork and report generation. A computer system is described that collects the necessary data on-line for accuracy and efficiency. The system can generate various reports relating to repair history, spare parts usage and preventive maintenance scheduling. It is implemented on a time-sharing minicomputer, and can reduce substantially the time spent by biomedical engineers in documenting their activities.

摘要:

A low-cost Medical Data Handling System (MDHS) has been developed on a Digital Equipment Corporation PDP 11V03 computer system with dual floppy discs using BASIC in a time-shared configuration. The MDHS can be called up by one or more users to collect, update, or store patient data on floppy discs. Various analysis options are available to generate reports for patient management or administrative purposes. All software is written in BASIC to facilitate changes or expansion, and to reduce the costs in transferring the software system to other low-cost microprocessor systems currently available. The MDHS can be used in a variety of hospital departments for data management by simple customization of the 1/0 software to take advantage of the general purpose routines. The system is currently in use for generating daily patient -summary clinical laboratory reports for ICU and CCU patients. (This is the second and concluding part of this article.)

摘要:

Hospitals use vast quantities of glass ampules, and opening these ampules may cause glass fragments to enter the contents. Aspiration of the ampule contents and injection hypodermically can allow fragments to enter patients, and the sterility of the contents cannot be assured. There is a need for further investigation to determine the clinical effects, and an immediate need for labelling to alert medical personnel. Syringe filters are not effective answers to the problem.
