Abstract: A humidifier having a reservoir, an exhaust opening, and a humidification unit including a motor driven fan with a suction tube attached thereto, a diffusion screen, and an intake opening. Water is drawn from the reservoir through the suction tube and dispersed towards the diffusion screen to cause mist which is combined with air drawn through the intake opening by the fan and expelled through the exhaust opening. An integral latch mechanism removably and replaceably attaches the suction tube to the fan to facilitate cleaning of the tube.

Abstract: A portable electric fan with fixed multiple support structure permitting orientation of the fan in various angular positions with respect to the support surface on which the fan is placed.

Abstract: An applicator is provided for applying a sheet of surgical material, e.g., an adhesion barrier or other surgical fabric, to internal body tissue. The applicator includes an expandable operating tip which is insertable into an endoscopic tube through an incision in a body to enable a surgeon to apply the adhesion barrier or other surgical fabric to tissue inside the body. A preferred embodiment of the applicator includes a set of telescoping tubes comprising an outer delivery tube, a intermediate deployment tube, and a inner irrigation tube. An expandable spreader tip is mounted at the distal end of the irrigation tube and connected to the distal end of the deployment tube. By advancing the deployment tube and irrigation tube relative to the delivery tube, the spreader tip is exposed at the distal end of the delivery tube. The spreader tip is expanded by movement of the deployment tube relative to the irrigation tube to spread the adhesion barrier over the tissue.
