This dictionary was begun on the basis of the inventory of medical equipment maintained for Liverpool Health Authority, to provide a brief description of all the items in use. However, the list has been extended with the aid of the reference works listed at the end of the book, and also as a result of comments received from readers of the draft text.

The object has been to provide rudimentary information about equipment which may be found in hospitals, and in medical research and teaching institutions. It is intended to be useful to all those concerned with the use, servicing, or purchasing of medical and scientific equipment.

There are many common terms and trade names which are used for medical equipment. These have only been included where we have found that the terms are frequently used, or, in the case of trade names, that the term is used to refer to a general type of equipment rather than just a single model. The descriptions of equipment are meant as a guide, and are not definitive specifications.

To assist the reader to make best use of the dictionary, Appendix 2 has been created to show entries listed according to subject. For instance, if an item found in a catalogue of medical equipment is not found in the dictionary, other relevant entries may be identified by examining the subject.

It is impossible to cover every item of equipment, and in any case, development, invention, and change in medical practice make it difficult to be truly up to date. However, we believe that all the commonly used items are covered, and that readers will find the information they require, in almost every case. Comments and suggestions, or information about difficulties in identifying equipment, will be gratefully received. The address to write to is The Institute of Medical and Dental Bioengineering, Royal Liverpool Hospital, Liverpool L7 8XP, in the United Kingdom.
