A New or Improved Surgical Dressing.
I, ALFRED SYKES, of Spring Place Mill, Springwood Street, Huddersfield,
in the County of York, Electrical Engineer, do hereby declare the nature of this
invention to be as follows:--
This invention relates to the production of a new or improved dressing for
surgical purposes in treating wounds sores and the like.
The object of my invention is to obtain an animal tissue of a spongy, absorbent
or cellular nature to be used as a dressing for wounds in lieu of the vegetable
tissue now used.
In carrying out my invention I take the bones of animals, principally the knee
and other bones which are of an open or cellular formation, and these I cut into
small pieces and boil for several days or until all the fat is removed.
I then place
the bone in a cold solution of hydrochloric acid of suitable strength and after
allowing it to stand for a day or two to remove the lime I place it in a solution of
soda for the purpose of neutralizing or removing the acid. I then squeeze or
press the softened bone dry and place it in a solution of carbolic acid to disinfect
it, or it may be made up in bottles containing a solution of carbolic acid.
The process above set forth may be varied or the bone may be otherwise treated
to prepare it for use as a dressing.
The animal tissue obtained as described is packed into the wound and spread
over it and is a non irritant dressing; is healthy, is quickly absorbed by the
living tissues, and, at the same time, it stimulates the grannulation tissue and so
accelerates the healing of the wound.
Other animal tissue of a cellular or open nature which may be found to have the
same action, can be added to or substituted for the bone.

A New or improved Surgical Dressing.
I, ALFRED SYKES, of Spring Place Mill, Springwood Street, Huddersfield,
in the County of York, Electrical Engineer, 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 the production of a new or improved dressing for
surgical purposes in treating wounds, sores and the like.

page_text: The object of my said invention is to obtain an animal tissue of a spongy, absorbent
or cellular nature, to be used as a dressing for wounds in lieu of the vegetable
tissue now used, in respect to which it is much superior.
For the purpose of carrying out my invention I take the bones of animals,
principally the knee and other bones which are of an open or cellular formation,
and these cut into small pieces and boil for several days or until all the fat is
removed. I then place the bone tissue in a cold solution of hydrochloric acid of
suitable strength, say, a ten per cent. solution and after allowing it to stand for a
day or two to remove the lime therefrom I place it in a solution of soda for the
purpose of neautralizing or removing the acid. The softened bone is subsequently
squeezed or pressed dry and then placed in a solution of carbolic acid to disinfect
it; or it may be made up in bottles containing a solution of carbolic acid.
The process of preparation above set forth may be varied or the bone may be
otherwise treated to prepare it for use as a dressing.
The animal tissue obtained as described is packed into the wound and spread
over it, and is a non irritant dressing is healthy, and is quickly absorbed by the
living tissues, at the same time stimulating the granulation tissue and so
accelerating the healing of the wound.
Other animal tissue of a cellular or open nature or formation which may be
found to have the same action can be added to or substituted for the bone.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
A surgical dressing composed of animal tissue of a spongy, absorbent or cellular
nature or formation such as the knee and other bones of open or cellular formation,
prepared in the manner and for the purpose substantially as herein set forth.
Dated this 10th day of May 1898.
