COLLISON INHALER, 1940

The Collison Inhaler is for the administration of measured quantities of drugs to the lungs using Oxygen from bottles. It consists of two phials for the medication a face mask and rubber tubing a chromed assembly of two valves and the input points for the phials, also are two controls, one marked ‘'Both phials, White phial, Amber phial and Only oxygen’’. The other control is marked, ‘’Off, Weak, Medium, and Full’’; an indicator is also fitted to measure the level of oxygen left in the cylinder, but the plastic is fogged and the inside can barely be read.
Also with the system is an envelope containing spare washers for the Phials and filter, an open-ended spanner for connecting the unit to a cylinder, and a key for the oxygen cylinder valve, and a strap to secure the cylinder to the wheeled sack truck used for moving gas cylinders. The chromed unit with the controls and fitted phials is fixed to the top of the cylinder when in use. There is a receipt for the purchase of the equipment from the Inhalation Institute dated 27th September 1940 for £1.8s.6d. To C. Tyler Esq., Queens Drive West. Peterborough, in the original envelope.
