Abstract
Abstract A method and a relaed apparatus for disinfecting, for reuse, separation devices for blood (10) is disclosed. Devices which may be disinfected, for reuse, include dialyzers, filters and membrane plasmapheresis devices including their interconnected and associated blood lines and intravenous administration sets. Subsequent aseptic reuse of the separation devices for blood (10) and their connected, associated blood lines and intravenous administration sets is possible.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
210 words
A disinfecting system which comprises: a separation device for blood defining a blood flow path and a second flow path separated from the blood flow path by semi-permeable membrane means, said device having a blood inlet and a blood outlet accessing the blood flow path and port means for accessing the second flow path; a blood inlet line having a device end and a patient end, the device end communicating with the blood inlet on said device; a blood outlet line having a device end and a patient end, the device end communicating with the blood outlet on said device; a manifold defining an interior cavity and an exterior having at least two connectors which communicate with the patient ends of said blood inlet line and said blood outlet line forming a common connection which allows said blood lines to be in interconnected flow relation through their patient ends, wherein said connectors on said manifold have orifices sized to substantially equilibrate resistance to fluid flow through lines intended to be connected thereto whereby each line receives a substantially equal volume of fluid flowing therethrough; and, disinfecting reuse solution carried within said separation device for blood, said blodd inlet line, said blood outlet line and said interior cavity of said manifold.

A disinfecting system which comprises: a separation device for blood defining a blood flow path and a second flow path separated from the blood flow path by semi-permeable membrane means, said device having a blood inlet and a blood outlet accessing the blood flow path and port means for accessing the second flow path; a blood inlet line having a device end and a patient end, the device end communicating with the blood inlet on said device; a blood outlet line having a device end and a patient end, the device end communicating with the blood outlet on said device; a manifold defining an interior cavity and an exterior having at least two connectors which communicate with the patient ends of said blood inlet line and said blood outlet line forming a common connection which allows said blood lines to be in interconnected flow relation through their patient ends, wherein said connectors on said manifold have orifices sized to substantially equilibrate resistance to fluid flow through lines intended to be connected thereto whereby each line receives a substantially equal volume of fluid flowing therethrough; and, disinfecting reuse solution carried within said separation device for blood, said blodd inlet line, said blood outlet line and said interior cavity of said manifold.
Claim 3
Dependent Claim
217 words
A disinfecting system for use with a separation device for blood defining a blood flow path and a second flow path separated from the blood flow path by a semi-permeable membrane means, the device having a blood inlet and a blood outlet accessing the blood flow path and port means for accessing the second flow path, said system comprising: a blood inlet line having a device end and a patient end, said inlet device end communicating with the blood inlet on the device; a blood outlet line having a device end and a patient end, said outlet device end communicating with the blood outlet on the device; a manifold defining an interior cavity and an exterior having at least two connectors which sealingly communicate with the patient ends of said blood inlet line and said blood outlet line forming a common connection with said blood lines and said manifold, wherein said connectors on said manifold have orifices sized to substantially equilibrate resistance to fluid flow through lines intended to be connected thereto whereby each line receives a substantially equal volume of fluid flowing therethrough, and the separation device being in fluid flow communication with disinfecting reuse solution carried within the separation device, said blood inlet line, said blood outlet line and said interior cavity of said manifold.
Claim 4
Dependent Claim
217 words
A disinfecting system for use with a separation device for blood defining a blood flow path and a second flow path separated from the blood flow path by a semi-permeable membrane means, the device having a blood inlet and a blood outlet accessing the blood flow path and port means for accessing the second flow path, said system comprising: a blood inlet line having a device end and a patient end, said inlet device end communicating with the blood inlet on the device; a blood outlet line having a device end and a patient end, said outlet device end communicating with the blood outlet on the device; a manifold defining an interior cavity and an exterior having at least two connectors which sealingly communicate with the patient ends of said blood inlet line and said blood outlet line forming a common connection with said blood lines and said manifold, wherein said connectors on said manifold have orifices sized to substantially equilibrate resistance to fluid flow through lines intended to be connected thereto whereby each line receives a substantially equal volume of fluid flowing therethrough, and the separation device being in fluid flow communication with disinfecting reuse solution carried within the separation device, said blood inlet line, said blood outlet line and said interior cavity of said manifold.
