Abstract
The invention is directed to a method for infusing a fluid from a liquid reservoir to the human body, comprising the steps of establishing a flow path for the fluid from the reservoir to the body, driving the fluid along said trajectory of flow and partially block said flow path downstream of the pump and upstream of the infusion point in the body, to increase the pressure of the fluid in the pump and keep the dissolved gases therein in solution. The invention is also directed to a method for infusing a fluid from a reservoir into the human body, comprising the steps of establishing a flow path for said fluid through a flexible wall vinyl tubing between the reservoir and the body, compressed said tubing by a peristaltic-type pump having at least one presser member arranged to deform the wall of the tubing segment at a first predetermined location thereof for dosing the flow of fluid therethrough, and establishing flow limiting means in a second predetermined location, for increasing the fluid pressure in the pipe between both predetermined first and second points, in order to facilitate the recovery of the shape of the wall of said pipe segment after its deformation by the pressing member.
