Abstract

A modular cassette infusion system for multiple infusions and the automatic administration of medicament. Sterile disposable cassettes are employed, which possess integral connections for the infusion lines, inlet valves, liquid distribution ducts, pump chambers, outlet valves, venting filters and chambers for the measurement of the infusion pressure. The system renders possible the infusion of 3, 6 or more different infusion solutions and medicaments held in disposable syringes via one or more small-volume pump chambers with outlet valve separately via a plurality thereof in parallel via only one vascular access point to the patient with the correct volume in a pulsating manner or in very small individual quantities substantially continuously in a quick succession one after the other without incompatible medicaments being mixed. After insertion in an universal, electromechanical and pneumatic or only electromechanical or furthermore electrohydraulic valve pump syringe actuating device the cassettes are operated with the aid of pressure surges. Since for control an electronic microprocessor control device is utilized, which can furthermore produce a printed record of an infusion and since a compatibility with other infusion equipment, as for example injection pumps is provided for, fixed programs and manual programming steps may solve the most types of infusion problem and provide for a substantial reduction in the work to be performed by nursing staff with an accompanying substantial reduction in costs. Additionally substantially enhanced improved patient safety is ensured.
