Abstract
Abstract A disposable speculum barrel member of circular cross section tapers to provide a larger proximal end and a smaller distal end. The barrel member includes a sleeve means having a concentric flange or window wall at one end which is joined to the proximal end of the barrel with the sleeve portion extending therefrom. An obturator in the barrel member may be withdrawn through the sleeve means. A handle member to which the barrel member is releaseably secured contains lighting means which is positioned around the sleeve means and adjacent the window wall and isolated from the interior of the barrel member.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
190 words
A single use disposable barrel member for use with a proctoscopic device having a light source therein comprising in combination a. a cylindrical cross-section tapered barrel, b. said tapered barrel having a smaller diameter opening at its distal end than at its proximal end, c. a sleeve means in the proximal end of said barrel and extending out of said proximal end, d. said sleeve means having a flange section at one end thereof defining a radially inwardly projecting annular window wall between the proximal end of said barrel and said sleeve means, e. said annular window wall being positioned in said proximal end of said barrel so that the light source of said proctoscopic device is positioned behind said annular window wall to pass light through said annular window wall and directly into the bore of said barrel, f. an obturator assembly in said barrel comprising a tip portion fitting smoothly in said distal end and a stem means attached to said tip portion and extending through said sleeve means, g. said sleeve means being of sufficient size to pass said obturator therethrough and out of said barrel member.
Claim 2
Dependent Claim
190 words
A single use disposable barrel member for use with a proctoscopic device having a light source therein comprising in combination a. a cylindrical cross-section tapered barrel, b. said tapered barrel having a smaller diameter opening at its distal end than at its proximal end, c. a sleeve means in the proximal end of said barrel and extending out of said proximal end, d. said sleeve means having a flange section at one end thereof defining a radially inwardly projecting annular window wall between the proximal end of said barrel and said sleeve means, e. said annular window wall being positioned in said proximal end of said barrel so that the light source of said proctoscopic device is positioned behind said annular window wall to pass light through said annular window wall and directly into the bore of said barrel, f. an obturator assembly in said barrel comprising a tip portion fitting smoothly in said distal end and a stem means attached to said tip portion and extending through said sleeve means, g. said sleeve means being of sufficient size to pass said obturator therethrough and out of said barrel member.
