Fluid connector assembly with neutral fluid displacement that limits connector damage
Fluid connectors assemblies that provide neutral fluid displacement without overlapping connectors are disclosed. A fluid connector assembly may include a housing and a pair of connectors (e.g., luers) coupled with the housing. A compressible member (e.g., bellow) is located within the housing. The first connector and the second connector each include a post with an opening. The compressible member can seal off the opening of the first connector from fluid entry. However, when the post of the second connector is inserted into the housing, the post of the second connector displaces the compressible member, causing the compressible member to uncover the opening, and further causes the compressible member to open in another location and receive fluid. Further, the compressible member seals each of the first connector and the second connector and forms a fluid path through the posts and the compressible member, with the seals regulating fluid flow.
1 . A fluid connector assembly, comprising:
a housing, comprising:
a first end,
a second end, and
an internal volume fluidly connected to the first end and the second end, and
a compressible member disposed in the internal volume, the compressible member comprising a bellows shape and forming a cavity;
a first connector secured with the housing at the first end, the first connector comprising:
a post having a distal-most end located in the cavity, the distal-most end of the post comprising a continuous surface, and
an opening formed in the post;
a septum forming a seal between the post and the compressible member; and
a second connector, when secured with the housing at the second end, displaces the compressible member and forms a first seal between the second connector and the compressible member such that a fluid can move between the second connector and the opening of the post.
2 . The fluid connector assembly of claim 1 , wherein a second seal is formed between the compressible member and the post.
3 . The fluid connector assembly of claim 2 , wherein the compressible member comprises a slit that is in an open position when the second connector is secured with the housing opens.
4 . The fluid connector assembly of claim 2 , wherein:
the housing comprises an inner surface, and
the first seal and the second seal prevent the fluid from contacting the inner surface.
5 . The fluid connector assembly of claim 1 , wherein:
the post comprises a first post disposed in the housing,
the second connector comprises a second post, and
the first post does not overlap the second post.
6 . The fluid connector assembly of claim 5 , wherein the compressible member is positioned between the first post and the second post.
7 . The fluid connector assembly of claim 1 , wherein the second connector compresses the compressible member from a first dimension to a second dimension less than the first dimension.
8 . A fluid connector assembly, comprising:
a housing comprising an internal volume;
a compressible member disposed in the internal volume, the compressible member comprising a bellows shape and an inner wall and a cavity defined by the inner wall;
a first connector secured with the housing, the first connector comprising:
a post having a distal-most end located in the cavity, the distal-most end of the post comprising a continuous surface, and
an opening formed in the post, the opening covered by the inner wall; and
a second connector; and
a septum forming a seal between the post and the compressible member,
wherein a first position of the compressible member comprises the inner wall covering the opening, and a second position of the compressible member comprises the inner wall uncovering the opening based upon the second connector.
9 . The fluid connector assembly of claim 8 , wherein:
the post comprises a first post disposed in the housing,
the second connector comprises a second post, and
the first post does not overlap the second post.
10 . The fluid connector assembly of claim 9 , wherein the first post and the second post are separated by a gap.
11 . The fluid connector assembly of claim 10 , wherein the compressible member comprises a slit located in the gap.
12 . The fluid connector assembly of claim 8 , wherein
a first seal is formed between the second connector and the compressible member, and
a second seal is formed between the compressible member and the post.
13 . The fluid connector assembly of claim 12 , wherein:
the inner wall comprises a first inner wall,
the housing comprises a second inner wall that defines the internal volume, and
a fluid entering the second connector is prevented from contacting the second inner wall based on the first seal and the second seal.
14 . The fluid connector assembly of claim 12 , wherein at least a portion of a fluid path between the first connector and the second connector, and through the opening of the post, is formed by the first seal and the second seal.
15 . A method for regulating an intravenous fluid, the method comprising, by a fluid connector assembly:
providing a housing, the housing comprising an internal volume;
receiving, at the housing, a compressible member in the internal volume, the compressible member comprising a bellows shape;
receiving, at a first end of the housing, a first connector, the first connector comprising a post having a distal-most end with a continuous surface and an opening formed in the post between the distal-most end and a proximal end of the post, such that the distal-most end of the post is positioned within a cavity of the compressible member;
providing a septum forming a seal between the post and the compressible member;
receiving, at a second end of the housing, a second connector;
displacing, based on receiving the second connector in a direction toward the post, the compressible member; and
forming, based on the displacing of the compressible member, a seal between the second connector and the compressible member such that that the intravenous fluid can move between the second connector and the opening of the post.
16 . The method of claim 15 , wherein forming the seal comprises forming a first seal, and wherein the method further comprises:
forming, by the second connector and the compressible member, a second seal.
17 . The method of claim 16 , further comprising directing, based on the first seal and the second seal, the intravenous fluid though the compressible member such that the intravenous fluid does not contact an inner surface of the housing.
18 . The method of claim 15 , wherein:
the post comprises a first post,
the second connector comprises a second post, and
receiving the first connector and the second connector comprises maintaining a gap between the distal-most end of the first post and the second post.
19 . The method of claim 18 , wherein maintaining the gap comprises positioning the second post in a non-overlapping manner with the first post.
