Abstract

A fluid transfer assembly includes one or more fluid conduit and a body portion. The body portion defines a fluid channel within the body portion that is in fluid communication which each of the one or more fluid conduits when the body portion is in an elongated state. The body portion has an elongated stat in which the body portion is configured to elongate in a range of 150 percent to 1500 percent from the unelongated state without breaking to facilitate removal of a mandrel from the fluid conduit.

First claim

The invention claimed is:

1. A fluid transfer assembly comprising:
one or more fluid conduits; and
a body portion engaged with the one or more fluid conduits, the body portion defining a longitudinal axis and a fluid channel within the body portion about the longitudinal axis, the fluid channel in fluid communication with each of the one or more fluid conduits, the body portion having an unelongated state in which the body portion is relaxed and an elongated state in which the body portion is configured to elongate in a range of 150 percent to 1500 percent in a direction perpendicular to the longitudinal axis from the unelongated state without breaking to facilitate removal of a mandrel from the fluid channel, the body portion defining one or more internal recesses that extend through the body portion in a direction perpendicular to the longitudinal axis, the one or more internal recesses each configured to be engaged to transition the body portion from the unelongated state to the elongated state, each of the one or more internal recesses are out of fluid communication with the fluid channel.

2. The assembly according to claim 1 , wherein the body portion defines one or more protrusions extending outwardly from the fluid transfer assembly.

3. The assembly according to claim 2 , wherein the one or more internal recesses are defined by sleeves positioned in a mold, the sleeves define the one or more internal recesses in the body portion upon removal of the fluid transfer assembly from the mold.

4. The assembly according to claim 1 , comprising a housing configured to receive at least a portion of the body portion and at least a portion of the one or more fluid conduits.

5. The assembly according to claim 4 , wherein the housing comprises a rigid material, the assembly comprising one or more fluid control devices configured to be engaged with at least one of the one or more fluid conduits and the body portion, and the housing to control fluid flow within the fluid transfer assembly.

6. The assembly according to claim 1 , wherein the body portion or the one or more fluid conduits comprises a polymeric material.

7. The assembly according to claim 6 , wherein the polymeric material comprises at least one of a thermoplastic conduit, a thermoset conduit, and a silicone elastomer body portion.

8. The assembly according to claim 6 , further comprising a collar attached around an end of at least one of the one or more fluid conduits adjacent to the fluid channel.

9. The assembly according to claim 8 , wherein the polymeric material is configured to at least partially cover the collar.

10. The assembly according to claim 9 , wherein the polymeric material is configured to substantially entirely cover the collar.

11. The assembly according to claim 1 , wherein the one or more fluid conduits is formed of a first material and the body portion is formed of a second material different from the first material, the one or more fluid conduits integrally formed with the body portion.

12. A fluid transfer assembly comprising:
a first fluid conduit;
a second fluid conduit; and
a body portion comprising an open end, the body portion including a fluid channel defined therein and in fluid communication with the open end, the body portion engaged with the first fluid conduit and the second fluid conduit such that the first fluid conduit and the second fluid conduit are secured within the body portion and in fluid communication with the fluid channel, the body portion capable of receiving a mandrel having a first protrusion and a second protrusion extending in a direction away from a longitudinal mandrel axis of the mandrel with the first fluid conduit capable of being received over the first protrusion and the second fluid conduit capable of being received over the second protrusion, the body portion having an elongated state in which the mandrel with the first protrusion and the second protrusion is removable through the open end, the body having an unelongated state in which the open end has a dimension less than the mandrel such that the mandrel is prevented from being removed through the open end, the body portion defining one or more internal recesses that extend through the body portion in a direction perpendicular to a longitudinal axis of the body portion, the one or more internal recesses each configured to be engaged to transition the body portion from the unelongated state to the elongated state, each of the one or more internal recesses are out of fluid communication with the fluid channel.

13. The assembly according to claim 12 , wherein the body portion has an elongation from the unelongated state to break of between about 150% and about 1,500%.

14. The assembly according to claim 12 , further comprising a housing configured to receive a portion of the body portion, a portion of the first fluid conduit, and a portion of the second fluid conduit.

15. The assembly according to claim 14 , wherein the housing is formed of a rigid material, the assembly further comprising a first fluid control device configured to engage the first fluid conduit and a second fluid control device configured to engage the second fluid conduit.

16. The assembly according to claim 12 , further comprising a collar attached around an end of the first fluid conduit adjacent the fluid channel.

17. The assembly according to claim 12 , wherein the body portion is formed of a polymeric material.

18. The assembly according to claim 12 , further comprising a mandrel, the mandrel configured to fill the fluid channel in the unelongated state of the body, the mandrel including a first protrusion and a second protrusion that extend in a direction away from the mandrel longitudinal axis, the first protrusion receiving the first fluid conduit thereabout and the second protrusion receiving the second fluid conduit thereabout when the mandrel is disposed within the fluid channel with the body in the unelongated state, the mandrel removable through the open end in the elongated state of the body.

19. A fluid transfer assembly comprising:
one or more fluid conduits; and
a body portion engaged with the one or more fluid conduits, the body portion defining a longitudinal axis and a fluid channel within the body portion about the longitudinal axis, the fluid channel in fluid communication with each of the one or more fluid conduits, the body portion having an unelongated state in which the body portion is relaxed and an elongated state in which the body portion is deformed from the unelongated state to be elongated in a direction perpendicular to the longitudinal axis, the body portion defining one or more internal recesses that extend through the body portion in a direction perpendicular to the longitudinal axis, the one or more internal recesses each configured to be engaged to deform the body portion from the unelongated state to the elongated state, each of the one or more internal recesses are out of fluid communication with the fluid channel.
