<p>A device that allows for serial (time) use of clean blood filters during the use of a heart lung machine. The device is comprised of a series of filters (10, 11, 12) and a switching mechanism (16, 13, 14, 15) that allows the new filter to be placed in the blood flow pathway while at the same time removing the old (previous) filter. A clean filter is always available, and filters for specific components of blood or those able to bind and remove specific biochemicals can be used.</p> |
