Vapor 19.3 Halothane: a Reliable Anaesthetic Vaporiser for the Administration of Halothane in Hospitals
The Dräger Vapor 19.3 Halothane is a precision device designed to enrich the fresh gas of an anaesthesia system with liquid halothane. Integrated into the circuit of a continuous flow anaesthesia machine, this model offers precise control of the concentrations administered. Unlike versions 19.1 and 19.2, the 19.3 model is specially equipped to integrate with Interlock 2 locking systems, allowing two vaporisers to be used simultaneously while preventing joint activation, thus eliminating any risk of anaesthetic agents mixing.
The Vapor 19.3 operates on a controlled bypass principle: fresh gas is partially directed into a vaporisation chamber containing halothane, where it becomes saturated with anaesthetic vapour. The remainder of the flow passes through a bypass channel. The combination of these two flows allows the exact concentration to be set using a notched dial. This precision is maintained by an integrated thermal compensation mechanism, which automatically adjusts the flow ratio according to the ambient temperature, while maintaining a strict tolerance range.
One of the major advantages of this model is its indexed filling system, which is specifically designed to prevent filling errors. The use of a dedicated halothane bottle adapter prevents confusion with other agents such as isoflurane or sevoflurane. This device also features an overfill safety feature, with an overflow port preventing the maximum level from being exceeded.
The Vapor 19.3 is calibrated to provide a stable concentration between 0.2 and 4% by volume (typical values for halothane), with reliable performance even under variable pressure or flow conditions. It can be used at atmospheric pressures between 700 and 1100 hPa and can be tilted up to 45° when fixed in place.
Its robust construction, combined with low agent loss in standby mode, ensures a long service life and optimum safety. Designed for exclusive use with halothane in accordance with ISO 5360 and prEN 1280, this vaporiser must be maintained regularly by qualified personnel in accordance with the manufacturer's recommendations.
The Dräger Vapor 19.3 Halothane is a safe and compliant solution for medical facilities seeking optimal and reproducible control of halothane administration, while meeting the most rigorous standards for safety and clinical effectiveness.
