Title: Computer system for processing patient information
Inventor: JONES KEITH TREVOR
IPC: G16H40/20
Filed: 2001-01-03
Abstract: A computer system for processing patient information enables efficient handling of the details and treatment of patients in a hospital, clinic or other healthcare facility. In use, the details and treatment of the patients are held on a first database in the form of large multipurpose database tables. This data, which can also be received from other systems or supplementary databases via a first server, is not aggregated, grouped or treated and consists of all type of patient activity and information. In order to reduce the time taken to search and query all patient activity, the details of each respective patient are extracted from the first database into a second database and the details of each respective patient are modified, using stored procedures, into readily accessible information. These stored procedures may include applying grouping fields to each data record to allow queries to focus quickly on pre-defined data tables, or applying user-defined count fields to each data record to allow quick aggregation of values. As the data is extracted from the first database it may undergo further validation checks and certain field values can be amended where errors are known to have occurred. The readily accessible information may then be accessed by an end user using local application software, which is connected over a public network to the second database. In use, local application software uses an Open Database Connectivity (ODBC) connection to couple to the second databases.

Preferably this chamber is disposed inside the tank and it has a coolant communication port 16 disposed at it's bottom portion. The regulating of the coolant level in this chamber is governed by the compressed gas supplied into the chamber via a liquid level regulating gas duct 20. A controller 13 is used to control the supply path of the compressed gas by operating solenoid control valves V1, V2, V3, V4 disposed in the ducts. The vapour from the vapour portion of the tank is vented off via the solenoid valve V3. Level switches 34a, 34b, 34c, temperature and pressure sensors 25, 26 are used to monitor the coolant and gas supply. A flowmeter 12 is disposed in the return pipe to monitor the rate of coolant returning to tank.
