ABSTRACT:
The disposable filter device of the invention has a housing with a fluid inlet chamber and fluid outlet chamber separated by a hydrophobic filter and having a hydrophilic filter on the inlet chamber side of the hydrophobic filter. In the liquid aspirating system, the disposable filter device is connected between the liquid collection container and the inlet to the aspirator, the hydrophobic filter functioning to prevent the passage of any liquid to the aspirator and the hydrophilic filter functioning to prevent a large accumulation of liquid on the inlet chamber of the filter device and to better assure against any spillage of liquid in the inlet chamber during replacement of the device.
