Abstract
An improved tissue specimen trapping device for collecting and separating solid particles and materials from body fluids has a porous separator that rests on a shelf-like annular ledge between upper and lower portions of the tissue collection container. At least one tissue collection basket removably disposed in the tissue collection container above the separator shelf has a porous bottom surface to filter tissue specimens from body fluids and has downward projections to the tissue collection basket above the separator shelf to create a space therebetween.
Claims19
A tissue collection container comprising:
- a housing having side walls and a base, wherein the housing defines an internal volume;
- a removable cover adapted to fit onto the side walls of the housing and form a top of the housing;
- a first port for receiving a first tube, wherein the first port is positioned in said cover;
- an indentation positioned on the side wall, wherein said indentation forms a ledge extending into the internal volume and defines a separation between an upper volume and a lower volume;
- a second port for receiving a second tube, wherein said second port is positioned in said cover and is in fluid communication with the upper volume;
- a separator shelf comprising a planar surface adapted to fit horizontally within said internal volume and be positioned atop the indentation, wherein the planar surface further comprises a first plurality of pores;
- a conduit connected to the first port and extending downward into the lower volume through said separator shelf;
- and
- a plurality of baskets, wherein each of said plurality of baskets is configured to be positioned on top of the separator shelf and wherein a base of each of said plurality of baskets comprises a second plurality of pores.
A tissue collection container comprising:
- a cylindrical housing having side walls and a base, said cylindrical housing defining an internal volume, wherein the cylindrical housing is divided into an upper portion, with a first diameter, and a lower portion, with a second diameter, and wherein the first diameter is larger than the second diameter;
- a removable cover adapted to fit onto the side walls of the cylindrical housing and form a top of the cylindrical housing;
- a first port for receiving a first tube, wherein the first port is positioned in said cover;
- a second port for receiving a second tube, wherein said second port is positioned in said cover and is in fluid communication with the upper portion;
- a separator shelf comprising a planar surface adapted to fit horizontally within said internal volume and be positioned between the upper portion and lower portion, wherein the planar surface further comprises a first plurality of pores;
- a conduit connected to the first port and extending downward into the lower volume through said separator shelf;
- and
- a plurality of baskets, wherein each of said plurality of baskets is configured to be positioned on top of the separator shelf and wherein a base of each of said plurality of baskets comprises a second plurality of pores.
