Abstract: A reusable and versatile device/system for mixing liquid drugs or solutions, before their administration into the human body. Mixing is carried out inside an entirely closed circuit, avoiding any contacts between the phases to be mixed and the external atmosphere. Closure of the circuit is realized partly by integral and indissoluble (permanent) connections and partly by reversible connections, such as vascular accesses, unidirectional or bidirectional check valves (NRV), or any other device which allows the creation of a closed circuit even after use, both to the system and the connected accessories, thus minimizing the risks of possible contaminations and/or infections to the patients.

Abstract: Object of the present invention is an entirely closed circuit apparatus for the administration of anesthetics, and/or other liquids into the human body during operation sessions. Such apparatus allows dosing an accurate amount of drug during each operation session and to each single patient without drug wastage and without using syringes with needles.

Abstract: An object of the present invention is an apparatus for administering liquids into the human body characterized in that it has at least one main loading channel provided with at least one main administration point able to be connected to at least one container holding the liquid and at least one secondary loading channel, separated from the first by a membrane, provided with at least one container holding the liquid. Such apparatus allows the independent and simultaneous administration of liquids incompatible with each other, into the human body.
