“Gaensler spirometer (Poulton & Son, Barry), 1960s.
This device was obtained from the MRC unit at Llandough Hospital, Wales after its closure in the 1980s. For demonstration purposes the timing device is shown attached to the upright where the counter balance weight would have been in place.”
From “Lung function testing in the doctor’s office”, by Burton M. Cohen, Journal of the Medical Society of New Jersey, Volume 60, No. 10, October 1963, page 485.
Developed by a team headed by Dr. John Cotes in the mid-1960’s. Performed spirometry, helium dilution FRC and single-breath DLCO. Design was acquired by P.K. Morgan and was manufactured and sold in Britain in the early 1970’s. From The Lancet, September 18, 1965, pp. 573-575. Reprinted in Inspire, 2018, Volume 19, No. 1, April as part of a memorial to Dr. Cotes.

From a Collins publicity photo dated 11/8/1962. There are two pairs of different sized spirometers, each intended to work in tandem. The purpose of this arrangement was not explained and this was likely a custom built system.
