Abstract: A bottle or container suitable for the sterile storage of liquid products therein and the administration therefrom of said products dropwise, the sterility being maintained even after first opening the bottle, without the need to include preservatives in the liquid product. The dispenser comprises a container body (1), a capsule (3) and a dropper assembly (2), ending with a rigid dropper nozzle (5) provided with one or more transversal ports communicating with the interior of the container body (1), covered by a resiliency deformable tubular sleeve (9). The dropper nozzle comprises a first portion having a smaller conicity (6) making out the distal end of the dropper and a second portion having grater conicity (7) on which three of such ports are preferably provided. The closure capsule (3) comprises an internal projection (21) which comes into contact, when the capsule is closed, with the tubular sleeve (9) at the position where the second portion having grater conicity (7) of the dropper nozzle is located.

Abstract: A device for cardiocirculatory assistance, also named a ventricular assist device, includes a haematic pump (50) with a pump body (7) having an inner space (21) defined by a rigid structure (51) and a pair of mobile membranes (16, 17) alternately driven in opposite directions by alternately positive pressure and negative pressure gas supplied to recesses (19, 20) surrounding the two membranes by means of an external pneumatic force generating unit (1). This device achieves excellent operation results while maintaining a reduced size and reduced weight.
