Summary
A basic Model M Boyle anaesthetic machine was modified to improve mobility and adaptability to different needs. The main changes from the commercial model (Canox) are the attachment of a wall rail system (British Oxygen Company) to the sides of the table top and above the flowmeters and the use of retractable reels for the storage of excess pressure tubing below the table top. This modification allows the easy placement of a variety of detachable anaesthetic and monitoring equipment and allows the machine to be used with the same convenience irrespective of the location of outlets for compressed gases. A special bracket was designed, attachable to the rail system, for the use with a modified Mapleson D system (Bain breathing circuit).
