Abstract
A medical drainage collection device of the disposable liner type wherein the problems of connecting and disconnecting the liner from the canister of a device is simplified by providing a resilient locking device on a canister cover which receives a snap-in tube connector fixed to the disposable liner. Pressure applied to the locking device resiliently releases the connector from the cover. The liner can be provided with a hydrophobic filter which filters air before reaching the vacuum system to prevent system contamination, and when covered by drainage liquid closes off further gas or air flow through the filter to also provide a maximum-fill shut-off thereby preventing overfilling.
