Medical device for administering a solution
First Claim
1. A medical device for administering a solution, said device comprising:
- a pump that is not inside a patient,a reservoir that is not inside the patient, anda communication structure for connecting said reservoir and said pump, wherein said communication structure is not inside the patient, anda line for connecting the medical device to the patient,a sensor for measuring an exposure of the solution, which is contained in the reservoir, to temperature, to humidity, or to pressure of the solution, or ageing or permeability of the reservoir, over the course of time,wherein the medical device uses a mathematical model in order to determine at any moment physical or chemical characteristics of the solution, which is contained in the reservoir, wherein the mathematical model takes account of a modification of the solution in the reservoir over the course of time as a function of an exposure to temperature, to humidity, or to pressure of the solution, or ageing or permeability of the reservoir; and
wherein the medical device informs the patient about refilling the solution or changing the reservoir depending on the modification of the characteristics of the solution.
