Abstract

Dispositivo dosificador para inyección de cementos óseos, que comprende un émbolo (1), un resorte (2) cónico compresible y un cuerpo de jeringuilla (3) donde se aloja el resorte (2) y el cemento. El deslizamiento longitudinal del émbolo (1) provoca la compresión del resorte cónico (2) y el acercamiento progresivo de sus espiras facilitando la inyectabilidad y el empuje del cemento óseo a lo largo del interior del cuerpo de la jeringuilla (3). La compresión del resorte cónico (2) facilita el mezclado homogéneo del cemento en el interior del cuerpo (3) por el efecto de cizalla que producen sus espiras al acercarse entre sí durante la compresión, la cual se extiende hasta que todas las espiras adquieren la misma mínima altura y se encuentran en un mismo plano. De este modo, se mantiene una agitación continua del producto a inyectar, garantizando su homogeneidad y evitando los problemas de filtrado por presión.
