Abstract
Abstract A biopsy specimen collector for use with a vacuum source includes a closed receptacle having an inlet opening and an outlet opening. The outlet opening is adapted to be connected to the vacuum source. A removable cover provides access into the interior of the receptacle. A fluid channel tube inside the receptacle has one end connected to the outlet opening, with its other end being open and being positioned substantially at the geometric centroid of the receptacle to facilitate operation of the collector without regard of its orientation during use.

Total Claims: 7
Claim 1
Independent Claim
298 words
A biopsy specimen collector capable of use in any orientation and adapted for use with a vacuum source comprising: a receptacle including a cover portion having a transverse wall and a sidewall projecting from and extending about the periphery of said transverse wall and having an open end; the edge of the sidewall surrounding the open end of the cover portion having a recess for receiving a collection portion; said sidewall further including an inlet opening and an outlet opening therethrough; an inlet tube disposed in said inlet opening and having a first bore extending from its distal end part way through said inlet tube and having a second bore extending from said first bore through said inlet tube to the inside of said cover portion; an outlet tube disposed in said outlet opening and having a first bore extending from its distal end part way through said outlet tube and having a second bore extending from said first bore through said outlet tube into the interior of said cover portion; a curved tube having a first end disposed in said second bore of said outlet tube and having a second end extending in a direction away from said transverse wall of said cover portion; said receptacle including a collection portion having a transverse wall and a sidewall projecting from and extending about the periphery of said collection portion transverse wall and having an open end; the periphery of said collection portion sidewall adapted to mate with the recess on the edge of the cover portion sidewall so that the cover portion and collection portion are tightly engaged together to form a receptacle wherein the interior boundaries of said receptacle define a geometric configuration, the open end of said curved tube being located substantially at said geometric centroid.

A biopsy specimen collector capable of use in any orientation and adapted for use with a vacuum source comprising: a receptacle including a cover portion having a transverse wall and a sidewall projecting from and extending about the periphery of said transverse wall and having an open end; the edge of the sidewall surrounding the open end of the cover portion having a recess for receiving a collection portion; said sidewall further including an inlet opening and an outlet opening therethrough; an inlet tube disposed in said inlet opening and having a first bore extending from its distal end part way through said inlet tube and having a second bore extending from said first bore through said inlet tube to the inside of said cover portion; an outlet tube disposed in said outlet opening and having a first bore extending from its distal end part way through said outlet tube and having a second bore extending from said first bore through said outlet tube into the interior of said cover portion; a curved tube having a first end disposed in said second bore of said outlet tube and having a second end extending in a direction away from said transverse wall of said cover portion; said receptacle including a collection portion having a transverse wall and a sidewall projecting from and extending about the periphery of said collection portion transverse wall and having an open end; the periphery of said collection portion sidewall adapted to mate with the recess on the edge of the cover portion sidewall so that the cover portion and collection portion are tightly engaged together to form a receptacle wherein the interior boundaries of said receptacle define a geometric configuration, the open end of said curved tube being located substantially at said geometric centroid.
Claim 3
Dependent Claim
20 words
The specimen collector of claim 1 further including a curette frictionally disposed in said first bore of said inlet tube.
Claim 4
Dependent Claim
33 words
The specimen collector of claim 1 further including a strainer affixed over the open end of said curved tube which prevents specimens from entering said curved tube when said specimen collector is inverted.
Claim 5
Dependent Claim
23 words
The specimen collector of claim 1 wherein the diameter of said inlet tube second bore is less than that of said first bore.
Claim 6
Dependent Claim
23 words
The specimen collector of claim 1 wherein the diameter of said outlet tube second bore is greater than that of said first bore.
Claim 7
Dependent Claim
23 words
The specimen collector of claim 1 wherein said inlet tube, said outlet tube and said cover portion are formed as a unitary element.
