<p>Adevicefortestingtheefficiencyofautociavesofthetype used in hospitals for steam sterilising porous loads such as surgical dressings, and particularly for detecting the presence of air in such a system, comprising first and second porous masses (10,11) of a substantially man-made material such as spun bonded polypropylene, superimposed so as to sandwich therebetween an indicator sheet (12) and a pair of porous and absorbent sheets (12a). This assembly is heldfirmlytoge- therwithin a perforated stainless steel box (13) having a closable lid (14). Forthe test the whole device is placed in a steam steriliser under normal working conditions. Subsequently, the test device is removed and the indicator sheet (12) inspected, any colour variation across the sheet providing an indication of incomplete sterilising conditions.</p> |
