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.
Abstract: An enzymatic intralenticular cataract treatment for removal of nuclear cortical and subcapsular regions of the cataractous lens through enzymatic digestion thereof which comprises introduction of a concentrated solution of a trypsin enzyme into the nuclear and cortical regions of a cataractous lens, and after enzymatic digestion removing the liquefied cataractous material. The procedure allows subsequent removal of the nuclear, cortical and subcapsular portions of a cataractous lens through a very tiny incision in the eye and lens capsule, leaving all other structures within the eye intact. Bovine and porcine trypsins are preferred.
Abstract: A medical-surgical method and apparatus for facilitating the replacement of ostomy appliances. A hollow cylinder, filled with sterile absorbant material is used to center the sealing ring prior to the replacement of the ostomy appliance.
