運びに不便で、特に最近多く用いられるディスポーザブ
ル品の場合には致命的な欠点となる。Low-pressure continuous suction devices are often used after thoracotomy to drain fluid while maintaining a constant internal pressure. A pressure regulating bottle is used to maintain a constant pressure. In this case, the pressure is set at the height of the water column pressure, so if you try to set the maximum value of the set pressure high in order to widen the application range, the overall height of the device tends to become too tall, making it difficult to handle and carry. This is inconvenient, and is a fatal drawback, especially in the case of disposable products, which are often used these days.
本発明は、現状のこのような問題点に鑑み、従来の低圧

提供する事を目的としたものである。In view of these current problems, the present invention has been developed to provide a system that allows the suction pressure to be set and regulated from very low to relatively high pressure without sacrificing the features of conventional low-pressure suction systems, and that is easy to handle and compact. The purpose of this invention is to provide a medical low-pressure suction device equipped with a simple pressure regulator.

The effects of 1) will be described. First, the suction pump (5)
When the upper space (12) of the first chamber (3) is evacuated to positive pressure, the first chamber (3) and the second tube (11
) into the capillary tube (8) in the first chamber (3) and exits through the lower opening (9) into the upper space (12). As a result, the upper space (12) always has a water column H1+
The suction pressure is kept constant by controlling the F power of H2. Moreover, the inside of the liquid drainage chamber (14) of the liquid collection part (2) connected to the upper space (12) is larger than the inside of the water seal chamber (14) than the inside of the upper space (12).
15) The water column is kept at a pressure H8 higher.
