Abstract

A medical device for use in connection with a connector of an indwelling line for cleansing a surface of a septum of the connector is provided. The medical device includes a housing including a proximal portion defining a cavity containing a quantity of microbial reducing agent, a distal portion defining a cavity for selective coupling with the connector of the indwelling line, and a partition separating the proximal and distal cavities, wherein the proximal and distal cavities are in fluid communication with one another; and a deformable member overlying an end of the proximal portion for maintaining the microbial reducing agent within the proximal cavity thereof. The microbial reducing agent being dispensable into the distal cavity, at least when the medical device is connected to the connector of the indwelling line, to awash a surface of the connector of the indwelling line and reduce microbes present thereon.

Claims

1. A medical device for use with a connector of an indwelling line, the medical device comprising:

a housing including a proximal portion and a distal portion separated from one another by a transversely extending partition that functions as a dividing wall, the partition having at least one opening defined therein, wherein each of the proximal portion and the distal portion defines a respective proximal cavity and a distal cavity, and wherein the proximal and distal cavities are in fluid communication with one another through the at least one opening in the partition, and wherein the distal cavity comprises a first coupling member configured to receive a portion of a second coupling member of the connector of the indwelling line within the distal cavity of the housing in a mating relationship;

a microbial reducing agent disposed within the proximal cavity of the proximal portion; and

a deformable member enclosing an end of the proximal portion for maintaining the microbial reducing agent within the proximal cavity of the proximal portion, the deformable member being collapsible into the proximal cavity to force the microbial reducing agent from the proximal cavity into the distal cavity.

2. The medical device according to claim 1, further comprising a valve member supported by the partition for enabling selective fluid communication between the proximal cavity and the distal cavity.

3. The medical device according to claim 2, further comprising an absorbent member disposed within the distal cavity.

4. The medical device according to claim 3, wherein the absorbent member is dimensioned to contact the connector of the indwelling line when the medical device is connected thereto.

5. The medical device according to claim 3, wherein the absorbent member is in contact with the partition.

6. The medical device according to claim 3, wherein the absorbent member is axially slidably disposed within the distal cavity.

7. The medical device according to claim 6, further comprising a biasing member interposed between the partition and the absorbent member, wherein the biasing member maintains the absorbent member at a distal-most location.

8. The medical device according to claim 7, further comprising a backing member supporting the absorbent member.

9. The medical device according to claim 8, wherein the backing member is at least one of porous and permeable.

10. The medical device according to claim 3, wherein the absorbent member is resilient.

11. The medical device according to claim 3, wherein the absorbent member contacts an outer surface of the connector of the indwelling line when the medical device is connected to the connector of the indwelling line.

12. The medical device according to claim 11, wherein the absorbent member exerts a mechanical cleansing action on at least a portion of the outer surface of the connector of the indwelling line upon a disconnection of the medical device from the connector of the indwelling line.

13. The medical device according to claim 3, wherein the microbial reducing agent is transferable to the absorbent member at least one of:

prior to an attachment of the medical device to the connector of the indwelling line; and

after an attachment of the medical device to the connector of the indwelling line;

whereby the absorbent member exerts a chemical/biological and a mechanical cleansing action on an outer surface of the connector of the indwelling line upon at least one of connection and disconnection of the medical device to and from the connector of the indwelling line.

14. The medical device according to claim 2, wherein the valve member is a duck-bill valve.

15. The medical device according to claim 1, wherein the microbial reducing agent is transferable from the proximal cavity to the distal cavity upon exertion of a sufficient force on the deformable member.

16. The medical device according to claim 15, wherein the microbial reducing agent is transferred through the opening in the partition.

17. The medical device according to claim 16, wherein the microbial reducing agent is transferred through a valve member.
