Shortage of Vacuum Bottles????

We use evac bottles or vacuum bottles on a daily basis for our thora/para patients. We are now OUT of them as a hospital. We are being told that there is a medical glass shortage and that this is affecting everyone. We have some paracentesis patients that are taking 2 hours to drain 6 L. This would normally take us 30-45 minutes. We are having to use the drainage bags instead of the bottles.

Is anyone else having problems getting bottles?
Does anyone have any alternative ideas???

Any help would be greatly appreciated.

Thanks,
