In circumstances of possible contamination, the safety of cell salvage may be increased by using a double suction setup. One suction line is connected to the cell salvage reservoir for suctioning blood, while the other is connected to regular wall suction for aspiration of contaminants.

To increase safety in cell salvage, a double suction setup is used, minimizing the risk of contamination. A vacuum trap is imperative to prevent back-suction, ensuring the integrity of the collected material and water supply. This system is critical for proper separation during procedures such as crystallization.

Explanation:

Cell salvage techniques involve collecting and reusing blood that a patient loses during surgery. To increase the safety of cell salvage, especially in scenarios with potential contamination, a double suction setup may be employed. This setup utilizes one suction line connected to the cell salvage reservoir for suctioning blood, while the second is connected to regular wall suction to aspirate potential contaminants.

A vacuum trap is crucial when connecting apparatuses to a vacuum source, such as a water aspirator, to prevent back-suction. This anti-back-suction mechanism is essential to maintain the sterility and integrity of both the suctioned substances and the water supply.

Overall, using a vacuum trap with a suction filtration system offers numerous benefits, including faster separation compared to gravity filtration and a drier, purer solid end-product which is essential in processes like crystallization.
