[The current situation of i-STAT (portable clinical analyzer) and its future view]

The i-STAT analyzer sold by Fuso Pharmaceutical. Industries Ltd. is a portable blood analyzer which analyzes blood gas, electrolytes and chemistry in whole blood using nine kinds of disposable cartridges. A biosensor and calibrant solution are built into the cartridge. Analysis is started by inserting the cartridge filled with 2-3 drops of fresh whole blood. The measurement result is displayed on the screen within 3 minutes after cartridge insertion. It is possible to take the i-STAT analyzer into the home medical treatment environment and to run a blood test next to the patient, since the i-STAT analyzer has the features of portability and a battery. The cartridge can be chosen and tested according to the clinical condition and symptoms of the patient. By bringing the i-STAT analyzer, cartridges and a portable printer into the home medical treatment environment, we can carry out examinations on the spot. The measurement result printed by the portable printer can be used as explanatory material for the patient and its family. The data can be managed using the Central Data Station (CDS), which is a management system for exclusive use of the i-STAT analyzer. If a network is established among patients, and the CDS is installed in a central medical institution, a local area medical information network can be set up. Using a satellite, communication with isolated islands or correspondence for telemedicine is expected.
