WARPING MEANS FOR THORACIC CAVITY DRAINAGE APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a compact suction drainage apparatus. SOLUTION: This apparatus has a liquid collection vessel 21 and a control module 20 for adjusting the gas flow rate and pressure in the suction drainage apparatus. The liquid collection vessel 21 has an outside wall which delineates the vessel body of a three-dimensional shape and a recess 25 of a three- dimensional shape which is disposed at this vessel body of the three-dimensional shape and faces outward. The recess 25 can accommodate the control module 20. The control module 20 can be telescopically fitted into the recess 25. The control module 20 has the control elements to control the flow rate of the gas flowing in the liquid collection vessel 21 and to control the gaseous pressure in the liquid collection vessel. All the control elements are not supported by the liquid collection vessel 21 but by the control module 20, thus the use of the control module 20 together with the vessels of various shapes is made possible. The control module 20 is telescopically fitted into the recess 25 and at least the main part of the control module 20 has the size and shape to allow the housing thereof into the vessel body of the three-dimensional shape.
