Abstract

A medical connector for providing a sterile connection between a multi-use portion and a single-use portion of a fluid delivery system is provided. The medical connector includes a fluid inlet port configured for removable engagement with a connection port of a multi-use disposable set (MUDS) to establish a fluid connection therewith and a waste outlet port configured for removable engagement with a waste inlet port of the MUDS to establish a fluid connection therewith. A patient fluid line is connected, at a first end, to the fluid inlet port and connected, at a second end, to the waste outlet port. Fluid flow through the patient fluid line is unidirectional from the first end to the second end. The patient fluid line is configured for being disconnected from the waste outlet port for delivering fluid to a patient. A multi-fluid delivery system having the medical connector and MUDS is also provided.

First claim

What is claimed is:

1 . A medical connector comprising:
a fluid inlet port configured for removable engagement with a connection port of a multi-use disposable set (MUDS) to establish a fluid connection therewith; a waste outlet port configured for removable engagement with a waste inlet port of the MUDS to establish a fluid connection therewith; and a patient fluid line connected, at a first end, to the fluid inlet port and connected, at a second end, to the waste outlet port, wherein fluid flow through the patient fluid line is unidirectional from the first end to the second end, and wherein the patient fluid line is configured for being disconnected from the waste outlet port for delivering fluid to a patient.

2 . The medical connector of claim 1 , further comprising a locking mechanism for removably securing the medical connector to the MUDS.

3 . The medical connector of claim 2 , wherein the locking mechanism has a flexible tab that is deflectable between an engaged position and a disengaged position by deflecting at least a portion of the flexible tab.

4 . The medical connector of claim 3 , wherein the flexible tab has a pressing surface that, when pressed, deflects the flexible tab from the engaged position to the disengaged position.

5 . The medical connector of claim 1 , wherein the fluid inlet port comprises a shroud surrounding at least a portion of the fluid inlet port.

6 . The medical connector of claim 5 , wherein the shroud has at least one indentation to facilitate handling of the medical connector.

7 . The medical connector of claim 5 , wherein the shroud has one or more ribs protruding from an outer surface of the shroud.

8 . The medical connector of claim 1 , wherein the fluid inlet port is shaped to prevent connection with the waste inlet port of the MUDS and wherein the waste outlet port is shaped to prevent connection with the connection port of the MUDS.

9 . The medical connector of claim 1 , wherein the medical connector has an asymmetrical shape such that the medical connector is connectable with the MUDS in one orientation only.

10 . The medical connector of claim 9 , further comprising at least one fin to prevent erroneous connection of the medical connector with the MUDS.

11 . The medical connector of claim 1 , wherein the second end of the patient fluid line has a connector configured for removable engagement with the waste outlet port while maintaining sterility of the second end.

12 . The medical connector of claim 11 , wherein the connector is in fluid communication with the waste outlet port when engaged with the waste outlet port.

13 . The medical connector of claim 11 , wherein the connector is a luer-lock connector.

14 . The medical connector of claim 1 , further comprising a one-way valve configured for maintaining unidirectional flow through the fluid inlet port into the patient fluid line.

15 . The medical connector of claim 1 , further comprising at least one sensor element configured for interacting with at least one sensor configured for detecting a presence or absence of the at least one sensor element indicating that the medical connector has been properly inserted or installed in the connection port.

16 . The medical connector of claim 15 , wherein the at least one sensor element has one or more reflective surfaces for reflecting visible or infrared light to the at least one sensor.

17 . The medical connector of claim 1 , wherein the fluid inlet port has at least one seal for forming a fluid-tight connection between the fluid inlet port and the connection port.

18 . A single-use disposable set connector, the connector comprising:
a fluid inlet port configured for removable engagement with a connection port of a multi-use disposable set (MUDS) to establish a fluid connection therewith; a waste outlet port configured for removable engagement with a waste inlet port of the MUDS to establish a fluid connection therewith; a spacer separating the fluid inlet port from the fluid outlet port; a locking mechanism configured for removably securing the connector to the MUDS, the locking mechanism having a flexible tab that is deflectable between an engaged position and a disengaged position by deflecting at least a portion of the flexible tab; a patient fluid line connected, at a first end, to the fluid inlet port; and a connector connected to a second end of the patient fluid line, wherein fluid flow through the patient fluid line is unidirectional from the first end to the second end, and wherein the connector is configured for removable fluid connection with the waste outlet port for delivering fluid to a patient.

19 . A method of delivering fluid using a single-use disposable set (SUDS) connector, the method comprising:
fluidly connecting a fluid inlet port of the SUDS connector with a connection port of a multi-use disposable set (MUDS); establishing a fluid communication between a waste outlet port of the SUDS connector and a waste inlet port of the MUDS; priming the SUDS connector by delivering fluid from the fluid inlet port to the waste outlet port through a fluid line; disconnecting the fluid line from the waste outlet port; and delivering fluid from the fluid inlet port to a connector through the fluid line.

20 . The method of claim 19 , further comprising locking the SUDS connector to the MUDS prior to priming the SUDS connector.
