Abstract

A male to female coupling for attachment between a connector of an enteral fluid delivery assembly and a connector of a syringe. In example embodiments, the male to female coupling comprises an annular space for collection of unused feeding fluids.

First claim

What is claimed is:

1 . A male to female enteral coupling comprising:
a body extending from a first end to a second end, the first end comprising a male hub surrounded by an outer cylindrical collar, an annular space defined between the male hub and the outer cylindrical collar, and a lumen defined within the male hub, and the second end comprising a female connector comprising a generally cylindrical body, and a receiver defined within the body and in communication with the lumen, the receiver configured for receiving a male connector, wherein the annular space is configured for collecting fluids discharged or overflowing during a post-delivery disconnection or separation of a fluid delivery syringe and an enteral fluid delivery device connector.

2 . The male to female enteral coupling of claim 1 , wherein the male to female coupling is configured for interconnection between the fluid delivery syringe and an enteral fluid delivery device connector.

3 . The male to female enteral coupling of claim 1 , wherein the first end is configured for engagement with a syringe connector of the fluid delivery syringe and the second end is configured for engagement with a male hub of the enteral fluid delivery device connector.

4 . The male to female enteral coupling of claim 1 , wherein the first end comprises a male ISO 80369-3 compatible coupling.

5 . The male to female enteral coupling of claim 1 , wherein the second end comprises a female ISO 80369-3 compatible coupling.

6 . The male to female enteral coupling of claim 1 , further comprising a flange extending from at least a portion of the body.

7 . The male to female enteral coupling of claim 6 , wherein the flange comprises an outwardly-protruding member, and wherein a width defined between the body an outermost portion of the outwardly-protruding member is a minimum of about 1.25 inches.

8 . The male to female enteral coupling of claim 1 , further comprising a tether for maintaining engagement of the body with the enteral fluid delivery device connector.

9 . The male to female enteral coupling of claim 1 , further comprising a lumen extension tip centrally positioned within the receiver of the cylindrical body, the lumen extension tip comprising a conduit defined therein and in communication with the lumen of the male hub of the first end.

10 . The male to female enteral coupling of claim 1 , further comprising a skirt projecting from the body and towards the second end, at least a portion of the skirt surrounding the cylindrical body of the second end.

11 . The male to female enteral coupling of claim 10 , further comprising one or more resilient clips formed with at least a portion of the skirt.

12 . A disposable enteral fluid delivery connector for interconnection between a fluid delivery syringe and a connector of an enteral feeding tube, the disposable enteral fluid delivery connector comprising:
a body extending along a longitudinal axis from a first end to a second end; a hub and an outer cylindrical collar defined at the first end, and an annular space defined between the hub and the outer cylindrical collar, the annular space terminating at an endwall, and the hub being configured for compatible engagement with the fluid delivery syringe; a receiver comprising a cylindrical body at the second end, and a lumen extending through the cylindrical body and hub so as to provide fluid communication through the body, the receiver configured for compatible engagement with the connector of the enteral feeding tube, wherein, with the body interconnected between the fluid delivery syringe and the connector of the enteral feeding tube, the fluid delivery syringe is disconnected from the hub of the first end such that any fluids discharged from the lumen of the hub or from the fluid delivery syringe is collected in the annular space defined at the first end of the body so as to prevent exposure of fluids to the connector of the enteral feeding tube.

13 . The male to female coupling of claim 12 , wherein the first end comprises a male ISO 80369 compatible coupling.

14 . The male to female coupling of claim 12 , wherein the second end comprises a female ISO 80369 compatible coupling.

15 . The male to female coupling of claim 12 , further comprising a flange extending from at least a portion of the body.

16 . The male to female coupling of claim 16 , wherein the flange comprises an outwardly-protruding member, and wherein a width defined between the body and an outermost portion of the outwardly-protruding member is a minimum of about 1.25 inches.

17 . The male to female coupling of claim 12 , further comprising a tether for maintaining engagement of the body with the enteral fluid delivery device connector.

18 . The male to female coupling of claim 12 , further comprising a lumen extension tip centrally positioned within the receiver of the cylindrical body, the lumen extension tip comprising a conduit defined therein and in communication with the lumen of the male hub of the first end.

19 . The male to female coupling of claim 12 , further comprising a skirt projecting from the body and towards the second end, at least a portion of the skirt surrounding the cylindrical body of the second end.

20 . The male to female coupling of claim 19 , further comprising one or more resilient clips formed with at least a portion of the skirt, the one or more resilient clips being configured for removable or permanent engagement with the connector of the enteral feeding tube.

21 . A method of connecting and disconnecting enteral feeding connectors to prevent contamination of components, the method comprising:
providing a fluid delivery device, the fluid delivery device comprising a connector; providing an enteral feeding tube assembly, the assembly comprising an elongate tube comprising at least one connector; providing a male to female coupling, the male to female coupling comprising a body extending along a longitudinal axis from a first end to a second end, a hub and an outer cylindrical collar defined at the first end and a receiver comprising a cylindrical body at the second end, wherein an annular space is defined between the hub and the outer cylindrical collar, the annular space terminating at an endwall and the hub being configured for compatible engagement with the fluid delivery syringe, and wherein a lumen extends through the cylindrical body and hub so as to provide fluid communication through the body, the receiver of the second end configured for compatible engagement with the at least one connector of the enteral feeding tube assembly; connecting the receiver of the male to female coupling with the at least one connector of the enteral feeding tube assembly; and connecting the hub of the male to female coupling with the connector of the fluid delivery device; discharging fluid from the fluid delivery device, through the lumen of the male to female coupling, and through the conduit of the enteral feeding tube assembly; disconnecting or separating the connector of the fluid delivery device from the hub of the male to female connector, wherein any fluids overflowing from the lumen of the hub of the male to female coupling are retained within the annular space; and disconnecting the receiver of the second end of the male to female coupling from the at least one connector of the enteral feeding tube assembly.
