Description: |
| Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. Little is known about this patent. There are no patent drawings available. This patent is in the database for reference only.
“This instrument consists of an exhausting cylinder, and a cup into which it screws. When applied to the breast, the cup is to be of such size as to receive it, when the raising of the piston will produce a vacuum. The rod, or stem, of the piston has a screw cut upon it, its whole length, and it is to be raised by a thumb screw, bearing upon the cap of the cylinder, which operates in the most gentle manner, and retains the piston in its place. The cup is made double; that is, there is one cup within another, there being a small space, say 1/16 of an inch, between them. The inner cup is perforated, all over, with minute holes; the object of this arrangement being to admit of the effect of the exhaustion being felt over the whole surface of the breast. The piston, and indeed the whole instrument, is without a valve.
When a small surface only is to be operated upon, the cup is unscrewed, and the open end of the syringe, with the piston down, is applied over the part.
The claim is to the rod and thumb screw, the double cup, and the application of the open syringe.
