Russell Emergency Chest Seal – First Aid Dressing – New Sealed, Expiry Date 2022



Here we have a new, unopened Russell chest seal from Prometheus Medical Ltd with a 2022 expiry date.
The Russell Chest Seal is a hydrogel-based dressing with an integral low-profile valve.  Its purpose is to cover penetrating chest wounds to allow air to escape from the pleural cavity without being drawn back in.  The aim is to minimise lung collapse associated with this injury and to facilitate lung re-inflation.
It is constructed from a thin but tough material which makes it very compliant. This allows it to open and close with very small changes in pressure. The valve is quite transparent so the dressing can be positioned accurately over the wound. A large base aperture gives some latitude for inaccurate placement in high stress environments. Four peripheral apertures are large enough (36Fr) to allow blood to escape if necessary without blocking the valve. The four apertures provide substantial redundancy: if up to three of the four holes become obstructed the valve will still remain fully operational.
The Russell Chest Seal is one of the largest chest seals currently available.
