13.Discussion
Clogging of the chest tube can contribute to retained hemothorax, pleural effusion, empyema, pneumothorax, and subcutaneous emphysema
Clinicians often employ large-diameter tubes, however, such large-diameter tubes are associated with increased pain
Internal active tube clearance system to keep the tube from clogging
Acute hemothorax model and device insertion
A 32 Fr chest tube was inserted into pleural cavities of five pigs.
On the left, a tube was connected to the chest canister, and on the right, the new system was inserted between the chest tube and chest canister.
Acute bleeding was mimicked by periodic infusion of blood.
The amount of blood drained from each chest cavity was recorded every 15 min for 2 h without tube manipulations.
After completion of the procedure, all residual blood and clots in each chest cavity were assessed
Significantly improved drainage compared to a standard chest tube of the same size.
Ease of use
There is one limitation in the material used in chest tubes. We used silicone for PleuraFlow because this material is considered more flexible and less painful to patients.
However, we used polyvinyl chloride for the standard chest tubes because a majority of chest tubes in contemporary practice are polyvinyl chloride tubes.
