Devices, systems, and methods for cleaning, disinfecting, rinsing, and priming blood separation devices and associated fluid lines
View Patent ↗Systems and methods for providing for the automatic instrument-based rapid reprocessing of an intact extracorporeal circuit for use in hemodialysis. The system includes a manifold with connectors for engaging a dialyzer as well as venous and arterial blood lines. The manifold is adapted to be moved from a dialysis machine to a reuse instrument without removing the dialyzer and associated blood lines. The system allows for reprocessing of the extracorporeal circuit wherein prior to the next treatment, there is no residual chemical disinfectant requiring testing, the extracorporeal circuit is pre-primed, the levels in the bubble traps are set, and all of the required quality assurance tests are performed and recorded.
1. A method comprising:
Providing a dialysis machine;
Providing a reuse machine;
Providing at least two patient dialysis sets, each of said patient dialysis sets including at least a blood separation device, a blood inlet line, and a blood outlet line;
Coupling a first patient dialysis set of the at least two patient dialysis sets to the dialysis machine;
Providing dialysis treatment to a first patient;
Configuring the dialysis set to provide a closed blood circuit within the first dialysis set;
Removing the first patient dialysis set from the dialysis machine;
Coupling the first patient dialysis set to the reuse machine; and
Reprocessing the first patient dialysis set for reuse, wherein the dialysis set further includes a manifold, wherein the manifold is attached to the blood separation device, and wherein the configuring step includes coupling a patient end of the inlet blood line and a patient end of the outlet blood line to the manifold.
2. The method of claim 1 further comprising coupling the second patient dialysis set to the dialysis machine; and providing dialysis treatment to a second patient.
3. The method of claim 2 further comprising removing the first patient dialysis set from the reuse instrument; storing the first patient dialysis set; removing the second patient dialysis set from the dialysis machine; and coupling the second patient dialysis set to the reuse instrument.
4. A method comprising:
providing a dialysis machine coupled to a blood separation device, a blood outlet line having a device end and a patient end, a blood inlet line having a device end and a patient end, and a manifold, the manifold attached to the blood separation device and having a plurality of connectors, the connectors being sized and configured for engagement with the patient ends of the blood inlet line and the blood outlet line;
coupling the patient ends of the blood inlet line and blood outlet line to the manifold connectors;
removing the blood separation device, the blood outlet line, the blood inlet line and the manifold as a single unit from the dialysis machine;
coupling the manifold to a reuse instrument for cleaning; and
cleaning the blood separation device, blood outline line, blood inlet line, and manifold.
5. The method of claim 4 further comprising disinfecting the blood inlet line, blood outlet line, blood separation device, and manifold.
6. The method of claim 4 further comprising priming the blood inlet line, blood outlet line, blood separation device, and manifold.
7. The method of claim 4 further comprising testing the blood inlet line, blood outlet line, blood separation device and manifold for leaks.
