An apparatus for draining fluids, for example, from a chest or pleural cavity, includes a collection chamber for collecting fluids through an inlet port for entry of the fluids. Also included is a dry or waterless suction control chamber in fluid communication with the collection chamber for regulating the degree of vacuum imposed in the collection chamber. If desired, a seal chamber can also be provided between the dry suction control chamber and the collection chamber so as to prevent any ambient or atmospheric air from passing into the collection chamber. The suction control chamber has a first inlet which is coupled to a suction source and a second inlet communicates with the ambient. A waterless regulator is provided for regulating the degree of suction imposed in the collection chamber at a plurality of predetermined preset levels of suction. This regulator is positioned between the suction inlet and the ambient inlet. The suction control chamber also has at least a visual indicator disposed between the regulator and the suction inlet for providing immediate confirmation of proper operation of suction in the collection chamber. The present invention also includes a device for retaining tubing under compression so as to provide self-sealing capability of the tubing during sampling or injection procedures.

Drainage device

Drainage device for draining bodily fluids from a patient

A drainage device, particularly adapted for use in medical procedures for draining fluids from a body cavity of a patient, incorporating a suction control chamber dimensioned and configured to provide an enhanced air and liquid flow pattern within the chamber. The suction control chamber might also include a baffle plate for air and noise control. The drainage device might further include a seal chamber and an improved high negativity relief valve. The present invention also includes a device, having an integral sampling or injection port, for coupling tubing.

Meterless drainage device with suction control

Apparatus for supporting a housing from a support including a bracket member formed of at least two opposed walls and having a post member extending between the walls, one of the walls capable of being positioned on the housing; and a hook member having one end rotatably secured about the post member for selective rotational movement from a first storage position to a second hanging position, the other end of the hook member being configured for engagement with the support, the one end of the hook member and the bracket being configured and dimensioned so that the hook member remains locked in the hanging position.
