Abstract

A hub component for a vented connector including a generally elongate cylindrical body having a first end and a second end. The first end of the hub component includes one or more fingers or clips for engagement with one or more vents of the vented connector. The second end of the hub component can be configured for compatible engagement with a carbon dioxide detector.

First claim

What is claimed is:

1. A hub component comprising:
an elongate body comprising a first end and a second end defining a length therebetween, and a lumen extending through the body from the first end to the second end;
a coupling portion formed at the first end, the coupling portion comprising a coupling portion receiver;
one or more elongate fingers formed at the second end, each of the one or more elongate fingers each having an inner surface; and
a receiver defined within a portion of the elongate body between the first and second ends, wherein the receiver comprises an inner surface, the receiver inner surface having a diameter that is tapered from a largest diameter adjacent to the inner surface of each of the one or more elongate fingers to a smallest diameter adjacent to the coupling portion receiver, wherein the receiver is configured for engagement with a connector-receiving portion of a connector,
wherein the hub component is formed from one piece,
wherein the connector-receiving portion comprises a male hub and further comprises an outer cylindrical collar surrounding the male hub and defining an annular space therebetween, the outer cylindrical collar comprising an endwall defining one or more vents, wherein the one or more fingers are configured for extension through the one or more vents when the receiver is connected with the male hub.

2. The hub component of claim 1 , wherein an outer surface of the one or more fingers comprises at least one engagement member formed thereon.

3. The hub component of claim 1 , wherein the male hub comprises a male ISO 80369-3 compatible coupling and the receiver comprises a female ISO 80369-3 compatible coupling.

4. The hub component of claim 1 , wherein an outer surface of the one or more fingers comprises an engagement member configured for engagement with the endwall of the collar when the male hub is connected with the receiver of the elongate body.

5. The hub component of claim 1 , wherein the one or more fingers comprise a pair of opposing fingers defining a pair of elongate channels therebetween.

6. The hub component of claim 1 , wherein the one or more fingers comprise a circular array of four space-apart fingers, wherein at least one of the four fingers comprises an engagement member extending from an outer surface thereof.

7. The hub component of claim 6 , comprising a first pair of fingers and a second pair of fingers, the first pair of fingers comprising at least one engagement member formed on an outer surface thereof at a first height and the second pair of fingers comprising at least one engagement member formed on an outer surface thereof at a second height, wherein the first height is not identical to the second height.

8. The hub component of claim 1 , wherein the length of the elongate body is between about 5-200 millimeters.

9. The hub component of claim 1 , further comprising a lumen extension tip formed with the receiver.

10. The hub component of claim 1 , wherein the coupling portion is configured for connection with a sensor or detector.

11. The hub component of claim 10 , wherein the sensor or detector can be a carbon dioxide detector, a pH indicator or other sensor or detector so as to ensure proper gastric placement of a feeding tube.

12. A component for coupling engagement with nutritional or medicinal fluid transfer systems or components, the component comprising: an elongate body extending between a first end and a second end and defining a lumen extending therethrough, the first end comprising a coupling portion, the second end comprising one or more fingers, and a receiver formed in the elongate body between the first and second ends, the receiver comprising an inner surface for compatible engagement with a male hub, wherein the inner surface has a diameter that is tapered from a largest diameter adjacent to the one or more fingers to a smallest diameter adjacent to the coupling portion, wherein the receiver is configured for engagement with a connector-receiving portion of a connector, wherein the component is formed from one piece,
wherein the connector-receiving portion comprises a male hub and further comprises an outer cylindrical collar surrounding the male hub and defining an annular space therebetween, the outer cylindrical collar comprising an endwall defining one or more vents, wherein the one or more fingers are configured for extension through the one or more vents when the receiver is connected with the male hub.

13. The component of claim 12 , wherein the coupling portion of the first end is configured for coupling engagement with another medical device, component, vessel, detector or sensor.

14. The component of claim 13 , wherein the detector is capable of determining the presence of carbon dioxide and/or measuring the acidity of a fluid.
