Patent number: 5104663Abstract: In a tissue irrigating solution of the type containing the combination of glutathione, bicarbonate, and Ringer solution (GBR), the chloride salts (Ringer solution) are packaged and stored in solution and the bicarbonate and glutathione are freeze-dried and packaged and separately stored in powder form until immediately preceeding the operation, at which time the bicarbonate and glutathione are dissolved directly into the solution of chloride salts. The resulting solution is mixed within 24 hours of use.Type: GrantFiled: September 4, 1990Date of Patent: April 14, 1992Assignee: Entravision, Inc.Inventors: Walter A. Newton, Douglas V. Carter

Patent number: 5052558Abstract: A method of filling, sealing and sterilizing a pharmaceutical package including a polypropylene bottle containing a balanced salt solution includes the steps of filling each bottle to maximum capacity to exclude residual air, the introduction of a silicone rubber gasket into the bottle cap to absorb pressure and prevent leakage during a steam sterilization procedure, and the enclosure of the filled bottles in a blister pack before steam sterilizing. The blister packs have Tyvek.TM. lids and are placed blister-side-up during the sterilization process to eliminate deformation of the blister during sterilization. Maximum filling of the bottle with liquid and the substantial elimination of air prevents dimpling of the bottle.Type: GrantFiled: July 27, 1990Date of Patent: October 1, 1991Assignee: Entravision, Inc.Inventor: Douglas V. Carter

Patent number: 4886498Abstract: A linking mechanism for irrigation/aspiration machines which includes a coupling member having a plug that is inserted into an opening in a receptacle on the face of the I/A machine. The plug projection is sealed in air tight relation to the wall surrounding the opening and an auxiliary prong(s) prevent rotation of the plug as well as lock the plug in the receptacle. The receptacle includes an arming switch activated responsive to proper seating of the plug in the receptacle to arm the peristaltic pump that is subsequently operated by a foot switch to generate a vacuum in the aspirant line.Type: GrantFiled: October 19, 1987Date of Patent: December 12, 1989Assignee: Entravision, Inc.Inventor: Walter A. Newton

Patent number: 4805377Abstract: A method of filling, sealing and sterilizing a pharmaceutical package including a polypropylene bottle containing a balanced salt solution includes the steps of filling each bottle to maximum capacity to exclude residual air, the introduction of a silicone rubber gasket into the bottle cap to absorb pressure and prevent leakage during a steam sterilization procedure, and the enclosure of the filled bottles in a blister pack before stream sterilizing. The blister packs have Tyvek.TM. closures and are placed blister-side-up during the sterilization process to eliminate deformation of the blister during sterilization. Maximum filling of the bottle with liquid and the substantial elimination of air prevents dimpling of the bottle.Type: GrantFiled: December 23, 1987Date of Patent: February 21, 1989Assignee: Entravision, Inc.Inventor: Douglas V.
