Abstract

Amortiguador para un dispositivo de administración de medicamentos, comprendiendo el dispositivo - un recipiente (12) que contiene medicamento, - un tapón (14) dispuesto en dicho recipiente y móvil para expulsar dicho medicamento a través de un medio (16) de administración de dosis, - un vástago (18) de émbolo que actúa sobre dicho tapón, y medios de fuerza que pueden ejercer una fuerza sobre dicho vástago de émbolo, en el que dicho amortiguador comprende - un manguito tubular que tiene los extremos proximal y distal opuestos; dicho manguito comprende un compartimento (22) formado por una pared de extremo cerrada en el extremo proximal del manguito y el extremo proximal del vástago de émbolo que está situado en un extremo abierto en el extremo distal del manguito; - un fluido dispuesto dentro de dicho compartimento (22); - al menos un paso (26) formado entre dicho compartimento y un espacio (32) anular entre dicho manguito y la pared interior de dicho recipiente (12); caracterizado porque - dicho fluido tiene una viscosidad alta; - una almohadilla elástica y hermética, que comprende una superficie (29) impermeable dispuesta contra dicho fluido, estando situada la almohadilla en dicho compartimento y dispuesta y diseñada para cubrir dicho al menos un paso cuando dicha almohadilla elástica está en una posición liberada, mediante lo cual, cuando se activan dichos medios de fuerza para ejercer una fuerza aplicada sobre dicho compartimento mediante dicho vástago de émbolo para expulsar medicamentos, dicha almohadilla elástica se comprime de manera que se libera dicho al menos un paso, expulsando dicho fluido en un espacio (32) anular entre dicho vástago (18) de émbolo y la pared interior de dicho recipiente (12), creando de ese modo una fuerza de amortiguamiento, y en el que al menos una ranura (30) que tiene una longitud predeterminada se extiende axialmente sobre la superficie de circunferencia exterior del vástago de émbolo formando al menos un paso entre la superficie circunferencial interior distal del manguito y la superficie circunferencial exterior proximal del vástago de émbolo para guiar cualquier aire atrapado dentro del compartimento.
