Abstract

Various implementations of a fluid collection system having a flexible liner are disclosed. In one exemplary variation, the fluid collection system may include a container having a top opening, a lid configured to close the top opening, and a flexible liner attached to the lid. The liner may be interposed between the lid and the container when the lid closes the top opening. The liner and the lid may define a substantially sealed interior space therebetween. The lid may include an access port through which the interior space receives fluid. The flexible liner may also be configured to controllably collapse as the fluid is removed from the interior space.

Claims

1. A fluid collection container comprising:

a flexible liner; and

a lid attached to the flexible liner such that the lid and flexible liner define a substantially sealed interior space therebetween, the lid including;

an opening configured for communication with at least one suction instrument through which the collection container receives fluid; and

an opening configured for communication with an access port of a suction source,

wherein the flexible liner is configured to extend to a first position and to collapse to a second position;

wherein the fluid collection container is configured to be received into a cavity, the cavity having a piston slidably positioned therein for dividing the cavity into an upper space and a lower space, and

wherein a suction force applied to the lower space draws the piston away from the lid to extend the flexible liner from the collapsed second position to the extended first position.

2. The fluid collection container according to claim 1, further comprising:

a holding mechanism configured to maintain the flexible liner in a substantially collapsed position prior to fluid collection.

4. The fluid collection container according to claim 1, wherein the fluid collection container is configured to be received in a cavity, the fluid collection container further comprising:

a seal configured to be sandwichably in place between the lid and the top of the cavity.

6. The fluid collection container according to claim 1, further comprising:

an opening configured to communicate with an evacuation source.

7. The fluid collection container according to claim 6, further comprising:

a safety mechanism inhibiting fluid from exiting the opening configured to communicate with an evacuation source, unless communication is established with the evacuation source.

8. The fluid collection container according to claim 7, wherein the safety mechanism includes a check valve.

9. The fluid collection container according to claim 6, wherein the opening configured to communicate with the evacuation source further includes a breakable seal.

10. The fluid collection container according to claim 1, wherein the fluid collection container is configured to be received in a cavity, and wherein the lid further comprises:

an opening configured to provide interstitial communication between a suction source and a space located between the exterior of the liner and the interior of the cavity.

11. The fluid collection container according to claim 1, further comprising:

a snap ring attaching the flexible liner to the lid.

12. The fluid collection container according to claim 1, wherein the liner is hot melted to the lid.

13. The fluid collection container according to claim 1, further comprising:

a valve located between the sealed interior space and the opening configured to communicate with the access port of a suction source, wherein the valve is configured to prevent fluid from entering the access port of the suction source once the valve is in contact with liquid.

14. The fluid collection system according to claim 13, wherein the valve is a float ball type valve.

15. The fluid collection system according to claim 13, wherein the valve includes a hydrophilic material.

16. The fluid collection container according to claim 1, further comprising:

a non-drip valve in at least one selected from a group consisting of the opening configured to attach to at least one suction instrument and the opening configured to attach to an vacuum source.

17. The fluid collection container according to claim 1, wherein the flexible liner is substantially collapsed in the second position.

18. The fluid collection container according to claim 1,

wherein the flexible liner is configured to collapse to a substantially collapsed second position, and

wherein a portion of the liner opposite the lid is flexible such that the portion abuttably conforms to an upper surface of a piston when extended in the first position and such that the portion collapses away from the direction of the piston when in the second position.

19. The fluid collection container according to claim 1, wherein the lid is configured to be inserted into a cavity, the lid having a side facing the cavity and a side facing away from the cavity, and

wherein the opening configured for communication with the access port of the suction source is provided on the side of the lid facing the cavity.

20. The fluid collection container according to claim 1, wherein the flexible liner is configured to expand against an inner wall of the cavity.

21. The fluid collection container according to claim 1, wherein the flexible liner is configured to expand in response to suction applied between the exterior of the flexible liner and an interior of the cavity.

3. A fluid collection container comprising:

a flexible liner; and

a lid attached to the flexible liner such that the lid and flexible liner define a substantially sealed interior space therebetween, the lid including;

an opening configured for communication with at least one suction instrument through which the collection container receives fluid;

an opening configured for communication with an access port of a suction source; and

a holding mechanism configured to maintain the flexible liner in a substantially collapsed position prior to fluid collection, wherein the holding mechanism comprises a breakable material,

wherein the flexible liner is configured to extend to a first position and to collapse to a second position;

wherein the fluid collection container is configured to be received into a cavity, the cavity having a piston slidably positioned therein for dividing the cavity into an upper space and a lower space, and

wherein a suction force applied to the lower space draws the piston away from the lid to extend the flexible liner from the collapsed second position to the extended first position.

5. A fluid collection container comprising:

a flexible liner; and

a lid attached to the flexible liner such that the lid and flexible liner define a substantially sealed interior space therebetween, the lid including;

an opening configured for communication with at least one suction instrument through which the collection container receives fluid; and

an opening configured for communication with an access port of a suction source, wherein the opening configured to communicate with at least one suction instrument is located in a section separable from the lid,

wherein the flexible liner is configured to extend to a first position and to collapse to a second position;

wherein the fluid collection container is configured to be received into a cavity, the cavity having a piston slidably positioned therein for dividing the cavity into an upper space and a lower space, and

wherein a suction force applied to the lower space draws the piston away from the lid to extend the flexible liner from the collapsed second position to the extended first position.
