Abstract
A urinary drainage bag incorporating a handle, inlet and outlet tubes, and a vent is formed from twosheets of flexible plastic material joined together along their peripheries. The arrangement of parts is such that assembly is accomplished using a two-cycle sealing operation which can be done at one or a plurality of sealing stations. An inlet tube section and an outlet tube portion are disposed between the upper and lower margins of the sheets and are in axial alignment. Steps in the preferred method of manufacture include positioning the inlet tube section, a portion of the outlet tube, and the handle on a common mandrel prior to sealing. This assembly is then placed between the sheets and a sealing operation performed to produce all required seals. A segment of the seal is shaped to provide a labyrinth passageway vent.
