| Description Of Item | Bellows for inflating the lungs – either as a separate resuscitator or as part of the EMO draw-over anaesthetic apparatus. A spiral spring in the bellows caused it to automatically refill whenever manual pressure on the bellows was released. Two valves under glass domes ensured unidirectional flow. Provided with a magnet to immobilise the outlet valve if/when an Ambu (non-rebreathing) valve is used. |
