Abstract
An arrangement for administering a medication to a patient. The arrangement is provided with a dual output element having first and second outputs, and an input for receiving the medication. A first catheter is coupled to the first output of the dual output element for delivering the medication intravenously, the first catheter being provided with a pressure valve that opens at a pressure P1. A second catheter is coupled to the second output of the dual output element for delivering the medication subcutaneously upon failure of the first catheter to deliver the medication intravenously, the second catheter being provided with a pressure valve that opens at a pressure P2, where P1>P2. A monitored radiopaque disk valve arrangement changes its status at a pressure P3 when a catheter occlusion is present, and is also used to obviate the need for two different types of catheters.
