发明名称 Drainage device for collecting liquids from a body cavity
摘要 A suction drainage device is provided, particularly for collecting liquids and any solids that may be carried therewith from a cavity of a body. Suction draws air or other gases from a collection chamber, and liquid and entrained particles from the cavity are drawn into a collection chamber. The device also has a water manometer. A liquid seal is also provided through which is drawn air and other gases from the collection chamber. A fluid control valve-like device is provided between various portions, chambers, and conduits of the device, and preferably between the device itself and atmosphere, such control device preferably being a gas permeable, liquid impermeable membrane, but optionally comprising a baffle. A facility is provided for breaking up bubbles of air at the inlet to the water in the manometer. Sampling openings are also provided, as are visual indications in the event of an upset of the device, an optional visual indication for magnifying observation of an air leak, an atmosphere opening on multiple planes to prevent its accidental blocking, an optional connection to a pump for auto-transfusion purposes, further a double collection chamber for simultaneously handling two cavities, and a removable calibrated tape for recording and maintaining a permanent record of patient progress.
