Abstract

The disclosed subject matter includes embodiments of fluid couplings that prevent or discourage misconnection of fluid lines. In embodiments, a coupling device may be configured according to lookup table that defines compatible configurations of connectors. The configurations may be based on the presence and absence of interference members at standardized locations on the respective connectors. The interference members may include posts that mechanically interfere with other posts, but can be inserted into holes when two connectors have a compatible configuration.

First claim

What is claimed is:

1. A method of making a coupling device for establishing a fluid connection between two fluid lines, the method comprising:
providing a kit having at least a first connector with a first set of one or more configurable interference elements and a second connector, wherein the first connector and the second connector are not configured to connect to each other until the first set of one or more configurable interference elements are configured; and
configuring the first set of one or more configurable interference elements in a first configuration that permits the first connector to connect with the second connector, wherein
the one or more configurable interference elements are configured to form multiple interfering element configurations, and
each configuration of the multiple interfering element configurations permits an interference-free connection to at least one second connector and prevents, by mechanical interference, connection to at least a third connector.

2. The method according to claim 1 , wherein
the second connector has a second set of the one or more configurable interference elements, and the method further comprises
configuring the second set of the one or more interference elements into a second configuration which is compatible with the first configuration of the first connector.

3. The method according to claim 2 , further comprising:
connecting the first connector to the second connector and thereby establishing the fluid connection between the two fluid lines.

4. The method according to claim 1 , wherein
the first connector includes a plurality of holes at predetermined locations on the first connector.

5. The method according to claim 4 , wherein
the configuring of the one or more configurable interference elements includes inserting posts into the holes on the first connector.

6. The method according to claim 2 , wherein
the first connector includes a first plurality of holes at predetermined locations on the first connector,
the second connector includes a second plurality of holes at locations corresponding to the predetermined locations on the first connector, and
the configuring the first set of the one or more configurable interference elements of the first connector and the second set of the one or more configurable interference elements of the second connector includes inserting posts into holes on the first connector and into holes on the second connector such that the inserted posts on the first connector do not interfere with the inserted posts on the second connector.

7. A method of making a coupling device for establishing a fluid connection between two fluid lines, the method comprising:
extracting an arrangement of interfering elements from a lookup table that identifies one or more compatible arrangements of the interfering elements on a first connector for every possible arrangement of the interfering elements on a second connector;
providing a kit having at least the first connector with one or more configurable interference elements and a second connector with one or more configurable interference elements; and
configuring the one or more configurable interference elements on the first connector and the second connector according to the arrangement extracted from the lookup table, the arrangement permitting interference-free connection between the first connector and the second connector and preventing, by mechanical interference, connection between the first connector and at least a third connector.

8. A method of making a coupling device, comprising:
providing a kit having a coupling device platform with at least one fluid line connector and at least one configurable interference element that may be modified to form at least two different coupling device arrangements; and
prior to connecting the at least one fluid line connector, modifying the configurable interference element to form one of the at least two different coupling device arrangements, wherein
a first of said two different coupling device arrangements is adapted for connection to a first configuration of external coupling devices,
a second of said two different coupling device arrangements is adapted for connection to a second configuration of external coupling devices, and
the second of said two different coupling device arrangements is adapted to prevent, by interference caused by engagement of said at least one configurable interference element, connection to the first configuration of external coupling devices.

9. The method of claim 8 , wherein the first of said two different coupling device arrangements is adapted to prevent, by interference caused by engagement of said at least one configurable interference element, connection to the second configuration of external coupling devices.
