Cassette infusion system
First Claim
1. A modular cassette infusion system for multiple infusions with a special suitability for intensive care comprising at least the following modules:
- a) an infusion pump cassette comprising at least one pump chamber with an inlet duct, an inlet valve, an outlet duct and an outlet valve,b) an infusion distributor cassette, which has two or more connections for infusion lines with associated inlet valves and following liquid distribution ducts, which open into one or more outlet connections,c) a disposable medicament administration cassette comprising a plurality of medicament containers respectively connectable to one another and to an outlet connection of the medicament administration cassette,wherein the outlet connections of the infusion distributor cassetter are connected to the inlet valve of the at least one infusion pump cassette via a connection hose,the outlet connection of the medicament administration cassette is connected to an inlet valve of a further pump chamber via a further connection hose, the further pump chamber further comprising an outlet valve, an inlet duct and an outlet duct,and the outlet ducts of the respective pump chambers are connectable to one another via their respective outlet valves.

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.
