ABSTRACT:
A surgical pleural drainage apparatus for draining fluids from the body of a patient is disclosed. The apparatus includes a container with a collection chamber. A suction outlet is provided on the container which is connected to a source of negative pressure and a fluid passageway connects the suction outlet to the collection chamber. A non-liquid one-way valve is provided in the fluid passageway for allowing fluid flow only from the collection chamber to the suction outlet. An air leak indicator is also provided in the passageway to indicate a flow of gases through the passageway and optionally the qualitative quantity of that flow. Preferably, the air leak indicator includes a visible liquid trap through which any gases flow and form bubbles which are visible. The liquid trap is prefilled with glycerine or a like liquid. The amount of negative pressure applied to the collection chamber is controlled by a suction control device. An excess negative pressure relief device and a positive pressure relief device are also provided for the collection chamber. Preferably, a pressure measuring device is provided for measuring the negative pressure in the passageway and a dynamic pressure measuring device is provided for measuring the pressure changes in the collecting chamber during respiration.
