Abstract

A manifold for collecting a tissue sample with a medical waste collection assembly. A base portion of a housing is removably engaged with a manifold receiver to provide a suction path from an inlet fitting receiving a suction line. A tray may be removably positioned within an accessory sleeve. Locating features facilitate defining a gap between a base portion of the tray and a lower barrier of the accessory sleeve. The tray may include a control surface to move the manifold between a sealing configuration, and a bleed configuration in which a second suction path is provided through the gap and below the tray. A backflow prevention valve may be disposed within the suction path between the tray and a filter element. Methods for collecting the tissue sample are also disclosed.

First claim

The invention claimed is:

1. A manifold for collecting a tissue sample through a suction line, the manifold comprising:
a housing defining a manifold volume, and an outlet opening in fluid communication with the manifold volume, wherein the housing comprises an accessory sleeve in fluid communication with the manifold volume, and an inlet fitting coupled to the accessory sleeve and configured to be removably coupled with the suction line, wherein the accessory sleeve comprises plateaus defining a trough therebetween; and
a tray configured to be removably positioned with the accessory sleeve and comprising a base portion defining porous features configured to collect the tissue sample, wherein the tray is configured to be supported by the plateaus to provide a gap between the trough and the base portion of the tray, and wherein the tray further comprises a control surface, and a sealing surface coupled to the control surface,
wherein the control surface is configured to receive an input from a user to cause a lower portion of the sealing surface to flex away from a lower aspect of the accessory sleeve to provide a suction path through the trough and into the manifold volume in a bleed configuration.

2. The manifold of claim 1 , wherein an upper aspect of the sealing surface remains engaged with an upper aspect of the accessory sleeve in the bleed configuration.

3. The manifold of claim 1 , wherein the housing further defines a bore having a first end opening into the trough and a second end opening into the manifold volume.

4. The manifold of claim 3 , wherein the inlet fitting extends upwardly from the accessory sleeve at a position proximal to where the first end of the bore opens into the trough.

5. The manifold of claim 1 , wherein the manifold comprises a body portion defining the outlet opening, and a cap portion removably coupled to the body portion and comprising the accessory sleeve.

6. The manifold of claim 5 , further comprising a filter element disposed within the body portion and configured to be accessed via decoupling the cap portion from the body portion.

7. The manifold of claim 6 , wherein the cap portion and the body portion comprise complementary couplers configured to facilitate the decoupling by relative rotation between the cap portion and the body portion.

8. The manifold of claim 7 , wherein the complementary couplers are keys comprising a barb, and keyways with at least a portion of the keyways sized to be less than a thickness of the barbs.

9. The manifold of claim 1 , wherein the tray further comprises a foot extending from the base portion, wherein the foot is configured to engage the plateaus with the tray removably positioned with the accessory sleeve.

10. The manifold of claim 9 , wherein the foot is U-shaped and bounds the porous features within the base portion.

11. The manifold of claim 10 , wherein the U-shaped foot is configured to bound the trough with the tray removably positioned within the accessory sleeve.

12. The manifold of claim 1 , wherein the control surface is on a grip comprising a first portion and a second portion extending from the sealing surface with the first and second portions configured to be pinched by the user to move the manifold to the bleed configuration.

13. A manifold for collecting a tissue sample through a suction line, the manifold comprising:
a housing defining a manifold volume, and an outlet opening in fluid communication with the manifold volume, wherein the housing comprises an accessory sleeve in fluid communication with the manifold volume, and an inlet fitting coupled to the accessory sleeve and configured to be removably coupled with the suction line, wherein the accessory sleeve comprises plateaus defining a trough therebetween, and a bore extending between the trough and the manifold volume; and
a tray configured to be removably positioned with the accessory sleeve and comprising a base portion defining porous features configured to collect the tissue sample, and a foot extending from the base portion, wherein the tray further comprises a control surface, and a sealing surface coupled to the control surface, wherein the foot is configured to be supported by upper surfaces of the plateaus with the tray removably positioned with the accessory sleeve for the base portion to be positioned above the trough,
wherein the control surface is configured to receive an input from a user to cause a portion of the sealing surface to move away from a lower portion of an accessory opening into the accessory sleeve to provide a suction path through the trough and into the manifold volume in a bleed configuration.

14. The manifold of claim 13 , wherein the foot is U-shaped and bounds the porous features within the base portion.

15. The manifold of claim 14 , wherein the U-shaped foot is configured to bound the bore in communication with the manifold volume with the tray removably positioned within the accessory sleeve.

16. The manifold of claim 13 , further comprising a filter element disposed within the manifold volume, wherein the housing is configured to permit access to the filter element for retrieval of the tissue sample.
