Abstract: A nozzle assembly for a fan unit includes an inner nozzle having a tapered outer diameter and a flow path radially inward from the tapered outer diameter with respect to a longitudinal axis of the nozzle assembly. The flow path is configured to guide a fluid flow and to expel the fluid flow through an inner outlet of the inner nozzle to a surrounding environment. The nozzle assembly also includes an outer nozzle disposed radially outward from the inner nozzle with respect to the longitudinal axis. The outer nozzle and the tapered outer diameter of the inner nozzle define an annular flow path therebetween. The annular flow path is configured to guide the fluid flow and to expel the fluid flow to the surrounding environment through an outer outlet of the outer nozzle. A cross-sectional area of the outer outlet is adjustable via movement of the inner nozzle, the outer nozzle, or both along the longitudinal axis of the nozzle assembly.

Abstract: A computer-based surgical services management system for communicating between sites of a surgical services facility including a computer workstation located at each site of the facility, a server in network communication with each workstation, and a database resident on the network. The database retains patient-specific data maintained temporarily by the workstation located at a site where a patient is located, the patient-specific data moving from site to site with the patient, and site-specific data, maintained at the site where the site-specific data is produced. The database is distributed to and contained within each workstation for editing by a user. A copy of the database is contained in each workstation and is duplicated on the server. The database is of an object-oriented design containing classes for patients, locations, resources, surgeons and anesthesiologists. Methods are assigned to each of the classes for updating information.
