Apparatus for infusion of liquids
First Claim
1. A device for infusion of liquids into human or animal bodies comprising:
- a reservoir means for infusion liquids isolated from a body being treated with such infusion liquid;
a delivery-dosing means operationally coupled to said reservoir means and to an outflow catheter adapted to be connected to a body being treated with the infusion liquid; and
a reduced-pressure generating means operationally engaged with said reservoir means which maintains a defined reference pressure value at the interconnection between said reservoir means and said delivery-dosing means which is lower than the pressure prevailing at an outflow opening of said outflow catheter.

Abstract
An apparatus for infusion of liquids into human or animal bodies which comprises a liquid reservoir having a reduced-pressure generating means associated therewith and an active delivery-dosing means, such as a roller pump, operationally coupled with the reservoir and with an outflow catheter having outflow opening within the body being infused. The reduced-pressure generating means, such as a volatile fluid, for example, a halogenated hydrocarbon, maintains a pressure at the point of connection between the reservoir and the active delivery-dosing means at a reference value which is lower than the pressure prevailing at the outflow opening of the outflow catheter.
