Some time ago, because of occasional inadvertent interruption of pleural suction after pulmonary resection, it was decided to construct an apparatus with an alarm system that would instantly indicate a drop in pressure. Since the first model was produced about 18 months ago it has gradually been modified and improved. Moreover, new uses have been discovered. It is now employed not only in chest surgery but also for gastrointestinal suction. Thus, it has been possible to combine in a single unit all the common forms of suction apparatus employed in general and thoracic surgery.
