Goldman halothane vaporiser
Date of manufacture:
This is a draw-over vaporiser that was originally designed for use in a non-rebreathing, demand system for dental anaesthesia. It is of simple design, having been calibrated to deliver no more than 3% vapour in clinical use. It exhibits low breathing resistance and has been used in closed systems with carbon dioxide absorption. It should be noted that, in this application, concentrations in excess of 3% halothan can be achieved and continuous monitoring of system concentration is therefore desirable. The control extends from OFF to ON through a non calibrated track. The example shown has cage mount (23 mm) tapers with the female taper pointing the direction of flow. The removable glass reservoir accepts a maximum of 30 ml halothane and is held in place by a swivelling yoke which prevents the device from being free standing. A threaded pin on the side of the device permits it to be mounted permanently on the back bar of an aneasthetic machine. It is neither temperature controlled no temperature compensated. Its portability and ease of emptying made it suitable for use by peripatetic anaesthetists.
