PROCESS FOR EXTRACTING BIOMEDICAL DEVICES. |
摘要 |
<p>A process for treating biomedical devices, especially contact lenses, involves contacting polymeric devices containing extractables with a solvent that dissolves and removes the extractables from the devices. The devices are subjected to at least two treatments with solvent to remove extractables in the devices. One of the treatment steps involves solvent used as a final rinse for a prior batch of devices. The solvent may be circulated through a series of tanks, in which case the devices are first extracted in the downstream tanks, followed by extraction in the first tank containing fresh incoming solvent.</p> |
