The founders had previously worked for Coxeter, another manufacturer of anaesthetic equipment and subsequently BOC after BOC took over both Coxeter and A. Charles King. During this time, both men already had their names on a significant number of patents for devices that had advanced anaesthesiology and increased patient safety in the process.
The company's first product was the Cyprane Inhaler - a hand-held Trilene drawover vaporiser for use during childbirth. This was manufactured at Cyprane's first factory - a converted garage - in Oxenhope.
In 1956, Halothane, a potent non-flammable volatile anaesthetic agent was introduced into clinical practice. Cyprane responded to this by introducing the world's first precision temperature-compensated anaesthetic vaporiser - the FluoTEC Mk. 1.
All Mk. 1 vaporisers were recalled, modified, and re-released as Mk. 2 variants in order to correct a critical design flaw which could cause the proportioning valve to stick thus posing a risk of overdosage to the patient.
February 2010 Added the following.
After the hand inhaler came the Tecota which was a more reliable, temperature controlled 'Trilene' vaporizer and was still used by the mid wife.
By the early 1960s there were other vaporizers developed; the 'draw over' used by the military and other field users. Also Mk 11 Halothane and the start of the Tec range that continues to be used to this day. Though not under the Cyprane name.
