Appliances for Sterilising Surgical Bandages or the like, and
Maintaining them Sterilised.
•
I, HAROLD IMRAY, of No. 28 Southampton Buildings, Chancery Lane, in the
County of London, Chartered Patent Agent, do hereby declare the nature of this
invention to be as follows:-
This invention relates to means of sterilising textures employed for bandages and
other surgical appliances, and of maintaining these textures in a sterilised condition
until they are required for use.
For this purpose, the pieces of texture required for bandages or other surgical
purposes are packed in tubes made of paper, parchment or like flexible and
impervious material, and these tubes are tied at each end somewhat like sausages,
but not closely, each end having within its tied part a plug of cotton wool or like
material which will allow passage of hot air or steam but will not give passage to
bacteria. The tubes thus charged are put in a chamber where they are exposed to
steam or to air heated above 100° C. whereby such bacteria as may be in the
textures are killed. The ends of the tubes are then tied tightly up over the cotton,
and in these packages the textures can be transported or kept in a sterilised
condition until required for use.
Dated this 20th day of July 1892.

Appliances for Sterilising Surgical Bandages or the like, and
Maintaining them Sterilised.
I, HAROLD, IMRAY, of No. 28 Southampton Buildings, Chaucery Lane, in the
County of London, Chartered Patent Agent, do hereby declare the nature of this
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
This invention relates to means of sterilising textures or fibres employed for
bandages and other surgical appliances, and of maintaining these textures or fibres
in a sterilised condition until they are required for use.
For this purpose, the pieces of texture or fibres required for bandages or other
surgical purposes are packed in tubes made of paper, parchment or like flexible and
impervious material, and these tubes are tied at each end somewhat like sausages,
but not closely, each end having within its tied part a plug of cotton wool or like
material which will allow passage of hot air or steam but will not give passage to
bacteria. The tubes thus charged are put in a chamber where they are exposed to
steam or to air heated above 100° C. whereby such bacteria as may be in the
textures are killed. The ends of the tubes are then tied tightly up over the
cotton, and in these packages the textures can be transported or kept in a
sterilised condition until required for use.

page_text: Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, I declare that what I
claim is :-
For sterilising and maintaining sterilised surgical bandages and the like,
enclosing these in a covering of impermeable material, having one or more
openings closed by a porous substance that will, on the one hand, allow of the
entrance of the sterilising air or other fluid into the casing while on the other
hand it will prevent the subsequent entrance of bacteria, substantially as described.
Dated this 30th day of March 1893.
