Place the steps for reprocessing (reusing) a dialyzer in correct order.

The process of reprocessing a dialyzer involves several critical steps that ensure the device is adequately cleaned and safe for reuse. The first step typically involves flushing the dialyzer to remove most of the blood, which is essential because it reduces the risk of contamination and prepares the dialyzer for the subsequent cleaning processes.

Once the flushing is completed, the next step is to disinfect the dialyzer using either a chemical or heat method. This step is crucial for killing any remaining pathogens and ensuring that the dialyzer is sanitized for future use.

After disinfection, the dialyzer needs to be cleansed with chemicals and through reverse ultrafiltration. This step helps to further remove any residual contaminants and blood remnants, ensuring comprehensive cleaning of the dialyzer.

Finally, testing the dialyzer is performed to verify that the membrane is intact. This is a critical safety measure; if there is any damage to the membrane, the dialyzer should not be reused.

The sequence of reprocessing is vital to ensure that each step effectively prepares the dialyzer for safe reuse while adhering to safety and health standards in medical practice.
