Abstract

A fluid drainage tool and method for utilizing the same is disclosed. The fluid drainage tool includes one or more pairs of vacuum members and a mechanical clamping mechanism. The mechanical clamping mechanism is coupled to the one or more pairs of vacuum members and is adapted to move the one or more pairs of vacuum members between an unclamped configuration and a clamped configuration. In the unclamped configuration, a gap formed by each of the one or more pairs of the vacuum members is larger than an original outer diameter of a pliable tube. In the clamped configuration, the gap is smaller than the original outer diameter of the pliable tube. In the clamped configuration, the one or more pairs of vacuum members compresses the pliable tube and generates a suction force within the pliable tube when translated along the pliable tube.

First claim

What is claimed is:

1. A fluid drainage tool, comprising:
a pair of vacuum members configured to move between an unclamped configuration and a clamped configuration and adapted to receive a pliable tube in a gap formed thereby;
a mechanical clamping mechanism coupled to the pair of vacuum members and adapted to move the pair of vacuum members between the unclamped configuration and the clamped configuration,
wherein, in the unclamped configuration, the gap formed by the pair of vacuum members is larger than an original outer diameter of the pliable tube and, in the clamped configuration, the gap formed by the pair of vacuum members is smaller than the original outer diameter of the pliable tube,
wherein, when the pair of vacuum members is moved from the unclamped configuration to the clamped configuration, the pliable tube is compressed by the pair of vacuum members, and
wherein, in the clamped configuration, the pair of vacuum members is adapted to be translated along a length of the pliable tube, thereby generating a suction force within the pliable tube for initiating a fluid flow through the pliable tube; and
a pair of guide members disposed adjacent to the pair of vacuum members and configured to move between the unclamped configuration and the clamped configuration, wherein, in the clamped configuration, the pair of guide members defines a gap that is partially or wholly larger than the gap defined by the pair of vacuum members.

2. The fluid drainage tool of claim 1 , wherein each of the guide members of the pair of guide members defines an annular groove at an outer surface thereof that is adapted to concentrically receive the pliable tube, and wherein the gap formed by the pair of guide members in the clamped configuration is defined as a distance from a bottom of the annular groove of a first guide member to a bottom of the annular groove of a second, corresponding, guide member.

3. The fluid drainage tool of claim 1 , wherein one or more of the vacuum members and the guide members comprise one or more rotatable wheels.

4. The fluid drainage tool of claim 1 , wherein the mechanical clamping mechanism comprises an over-center linkage coupling the pair of vacuum members, with the over-center linkage in an unlocked configuration while the pair of vacuum members is in the unclamped configuration and in a locked configuration while the pair of vacuum members is in the clamped configuration.

5. The fluid drainage tool of claim 1 , further comprising:
a first housing disposed between the mechanical clamping mechanism and a first vacuum member of the pair of vacuum members, wherein the first vacuum member of the pair of vacuum members is rotationally coupled to the first housing; and
a second housing disposed between the mechanical clamping mechanism and a second vacuum member of the pair of vacuum members, wherein the second vacuum member of the pair of vacuum members is rotationally coupled to the second housing.

6. The fluid drainage tool of claim 5 , further comprising:
a fixing link coupled to each of the first housing and the second housing via revolute joints at a fixed end of the fluid drainage tool, such that each of the first housing and the second housing are translationally fixed and rotatable relative to the fixing link.

7. The fluid drainage tool of claim 6 , wherein the mechanical clamping mechanism further comprises a mechanical linkage comprising a first link coupled to the first housing via a first joint at a movable end of the fluid drainage tool, opposite the fixed end of the fluid drainage tool, and a second link coupled to the second housing via a second joint at the movable end of the fluid drainage tool, wherein the first joint and the second joint are revolute joints.

8. The fluid drainage tool of claim 7 , further comprising a handle fixed to one of the first link and the second link and adapted to be movable by an operator of the fluid drainage tool and act as a lever to actuate the mechanical linkage to move the fluid drainage tool between the unclamped configuration and the clamped configuration.

9. The fluid drainage tool of claim 1 , comprising a first pair of guide members disposed at a fixed end of the fluid drainage tool and a second pair of guide members disposed at a movable end of the fluid drainage tool, wherein each of the pairs of guide members forms a gap that is larger than the gap formed by the pair of vacuum members in the clamped configuration and each of the guide members of the pairs of guide members is adapted to contact an outer surface of the pliable tube, and a first guide member of each of the pairs of guide members is rotationally coupled to a first housing and a second guide member of each of the pairs of guide members is rotationally coupled to a second housing.

10. A method of initiating a fluid flow through a pliable tube, the method comprising:
positioning the pliable tube within a gap formed by a pair of vacuum members disposed in an unclamped configuration;
moving the pair of vacuum members to a clamped configuration via actuation of a mechanical clamping mechanism coupled to the pair of vacuum members,
wherein, in the unclamped configuration, the gap formed by the pair of vacuum members is larger than an original outer diameter of the pliable tube and, in the clamped configuration, the gap formed by the pair of vacuum members is smaller than the original outer diameter of the pliable tube, and
wherein, when the pair of vacuum members is moved from the unclamped configuration to the clamped configuration, the pliable tube is compressed by the pair of vacuum members; and
positioning the pliable tube within a gap formed by a pair of guide members disposed adjacent to the pair of vacuum members and configured to move between the unclamped configuration and the clamped configuration, wherein, in the clamped configuration, the gap formed by the pair of guide members is partially or wholly larger than the gap defined by the pair of vacuum members.

11. The method of claim 10 , further comprising, in the clamped configuration, translating the pair of vacuum members along a length of the pliable tube, thereby generating a suction force within the pliable tube.

12. The method of claim 10 , wherein each of the guide members of the pair of guide members defines an annular groove at an outer surface thereof that is adapted to concentrically receive the pliable tube, and wherein the gap formed by the pair of guide members in the clamped configuration is defined as a distance from a bottom of the annular groove of a first guide member to a bottom of the annular groove of a second, corresponding, guide member.

13. The method of claim 10 , wherein one or more of the vacuum members and the guide members comprise one or more rotatable wheels.

14. The method of claim 10 , wherein the mechanical clamping mechanism comprises an over-center linkage coupling the pair of vacuum members, with the linkage in an unlocked configuration while the pair of vacuum members are in the unclamped configuration and in a locked configuration while the pair of vacuum members are in the clamped configuration.

15. The method of claim 14 , wherein the mechanical clamping mechanism further comprises:
a first housing disposed between the linkage and a first vacuum member of the pair of vacuum members, wherein the first vacuum member of the pair of vacuum members is rotationally coupled to the first housing; and
a second housing disposed between the linkage and a second vacuum member of the pair of vacuum members, wherein the second vacuum member of the pair of vacuum members is rotationally couple
