In the angiocardiographic examination of a patient with cardiovasucular disorders, any technical mistake should never be allowed. So, the apparatus must have full safety and high trustworthiness. The instrumentation required for angiocardiographic exminations is a combined system that consists of many kinds of instruments (A.O.T.Injector, V.T.R., Cine Camera, Spot Camera, M.E.Equipments). For improving the safety and reliability of this instrumentation as a whole system, we investigated many technical problems which might occur during the angiocardiographic procedure, based on our 8 years experiences, and equipped several safety mechanisms, as follows. 1) All control equipments were centralized. 2) Several automatic safety guarded control systems, 3) a switch boad for the aid of confirmation of the procedures, 4) the safety device for injection, (against a meaningless and harmful injection of contrast media without any x-ray filming.) 5) and a remote control switch for the simultaneous recording of the x-ray filmings, injection signal and E.K.G., were all equipped.
