<p>A process for the administration of insulin or similar long-term medicaments utilizing an elastic membrane dividing a reservoir into two chambers, one of which holds the medicament and the other containing a temperature-dependent vapour pressure and the remaining liquid propellant gas. By means of the membrane, the medicament, permanently pressurized by the propellant gas, is injected into the body through an outlet opening. The invention achieves differing ratios of medicament dosage by providing for external raising of the temperature of the propellant and thereby the pressure of the gas, and thus increasing the injected quantity at required time intervals. It is preferred that the dosage be dependent on the level of blood sugar in the body.</p> |
