Coupling of H1 to a central laboratory computer, automated evaluation of instrument alarms.

Everyone who has worked with an H1 from Technicon knows that it pours out a vast number of asterisks and error flags and that the same information is hidden in different places. After comparing a great number of samples from H1 with manual methods, we found that we could reduce the number of alarms of medical significance to about 20. So we built a microcomputer which sends the test results, the asterisks and 20 user defined alarm flags to the host computer where the verification takes place. The verification program automatically approves of tests where no alarms, asterisks or high or low values occur. Tests with any kind of alarm or asterisk are displayed. Doubtful results are automatically deleted following specified rules, the meaning of the asterisks can be studied on a switch-screen like on H1, and the technician can take the appropriate action, microscopy, rerun or checking H1.

[Modularization by the open standard. (I)].

We are proceeding with the project called "Open LA21 Project" in the course of the clinical laboratory automation toward the 21st century. With the modular system that realizes integration, downsizing, a reasonable price, and is the future course in the clinical testing automation system as well, we aim to establish common standards among manufacturers as the only way to create user friendly market environments where the proper competition exists among the manufacturers. The common standards which are in preparation by the participating companies as "Open module system standards" are the standards which are going to be made public. They are intended to guarantee connection, compatibility of the products in conformity with the standards. In this project, we intend to realize the modular system that integrates each field, such as chemistry, hematology, coagulation/fibrinolysis, immunology, urinalysis in an early stage, and contribute positively to restructuring and upgrading the "raison d'etre" of the 21st century clinical testing.

The development of an automated vascular laboratory.

Conventional vascular laboratory investigations such as Doppler ultrasound and photoplethysmography refilling tests produce results which require tedious cutting of chart recorder paper and calculation with the aid of ruler and pocket calculator. We have connected vascular lab equipment to a microcomputer which is able to record the data, generate reports and analyse the curves.
