The AN-50 Thorovac is a one gallon capacity, disposable, thoracic pump and collection bottle complete with electric motor, vacuum regulator, under water seal and connecting tube sealed into the top.  It creates a simple three bottle chest pump in one bottle that is packaged sterile and ready for immediate use with the addition of only a small amount of sterile water.  It is available in both 110 VAC and 220 VAC models.

The AN-50 Thorovac may be easily emptied by unscrewing the lid rim from the plastic bottle.  All the apparatus stays with the top.  Empty the bottle and then reassemble.
