Abstract

A tissue sample collection trap for trapping tissue samples for use with a suction sample collecting device comprising a cylindrical container either translucent or opaque with a suction connector element with a port provided at one end to connect to and cooperate with a suction device and the opposite container end open and adapted to accept a cap, the cap being either solid for continuous suction or provided with a control port through the end and into the container to be manually obstructed for suction by the operator and the diameter of a section of the inside of the container at the suction connector element and reduced forming a ledge adapted to hold a removable tissue trap assembly, and a tissue trap assembly comprising two round discs with a plurality of perforations forming screens and adapted to trap specimens and to slidably engage with and within the container and a hollow tubular handle provided to separate the discs extending axially and through the discs for slidably removing the tissue trap assembly from the container and providing a relief pathway for flow of excessive suction, and a collector connector means with a port provided on the perimeter of the container which is either permanent and molded to the container or is a coupling element adapted to accept various sizes and styles of connectors and is adapted to connect to and cooperate with a suction sample collecting device.

Claims

1. A tissue sample collection trap comprising a cylindrical container with a suction connector means provided at one end of the container with a port into the container and adapted to connect to a suction means and cooperating therewith, the opposite end of the container being open and adapted to accept a removable cap, a removable cap adapted to fit the container at the open end of the container, the diameter of a section of the inside of the container at the suction connector means end being reduced forming a ledge within that section of the container and adapted to hold a removable tissue trap assembly, a removable tissue trap assembly adapted to slidably engage with the container and comprising two round discs with a plurality of perforations on the surface thereby forming screens adapted to slidably engage with the container and to trap collected tissue samples while allowing effluent to flow through the screens and a hollow tubular handle provided to separate the discs and extend axially from the center of the discs and through the discs to provide a relief pathway for excessive suction and to provide for manual slidable removal of the tissue trap from the container, and a collector connector means with a port into the container extending radially on the perimeter of the container at a positon between the open end of the container and the reduced diameter section at the other end of the container and adapted to connect with a tissue sample collecting device and cooperating therewith to allow tissue samples to be drawn through a port in the collector connecting means and into the container from the tissue sample collecting device.

2. The tissue sample collection trap of claim 1 wherein the cap is solid to allow continuous suction within the container.

3. The tissue sample collection trap of claim 2 wherein the container is opaque.

4. The tissue sample collection trap of claim 3 wherein the collector connector means is permanent and is molded to the container.

5. The tissue sample collection trap of claim 3 wherein the collector connecting means comprises a coupling means adapted to accept various sizes and styles of connectors.

6. The tissue sample collection trap of claim 2 wherein the container is translucent to allow the operator to observe the tissue samples being collected.

7. The tissue sample collection trap of claim 6 wherein the collector connector means is permanent and is molded to the container.

8. The tissue sample collection trap of claim 6 wherein the collector connector means comprises a coupling means adapted to accept various sizes and styles of connectors.

9. The tissue sample collection trap of claim 2 wherein the collector connector means is permanent and is molded to the container.

10. The tissue sample collection trap of claim 2 wherein the collector connector means comprises a coupling means adapted to accept various sizes and styles of connectors.

11. The tissue sample collection trap of claim 1 wherein the cap has a control port formed through the end of the cap and into the container and cooperating therewith to allow air to flow through the container to the outside when the control port is not manually obstructed by the operator and to provide suction within the container when the control port is manually obstructed by the operator.

12. The tissue sample collection trap of claim 11 wherein the container is opaque.

13. The tissue sample collection trap of claim 11 wherein the container is translucent to allow the operator to observe the tissue samples being collected.

14. The tissue sample collection trap of claim 4 wherein the collector connector means is permanent and is molded to the container.

15. The tissue sample collection trap of claim 4 wherein the collector connector means comprises a coupling means adapted to accept various sizes and styles of connectors.

16. The tissue sample collection trap of claim 1 wherein the container is translucent to allow the operator to observe the tissue samples being collected.

17. The tissue sample collection trap of claim 1 wherein the collector connector means is permanent and is molded to the container.

18. The tissue sample collection trap of claim 1 wherein the collector connector means comprises a coupling means adapted to accept various sizes and styles of connectors.

19. The tissue sample collection trap of claim 1 wherein the container is opaque.
