Abstract

Esta unidad posee cámaras -2-2a-2b-2c- de diferente seccion transversal, consecutivamente dispuestas de menor -2- a mayor -2a-2b-2c- a partir del extremo de inyeccion -1a- y en cuyo interior hay sendas sustancias -10a-10b-10c-10d- que se mezclan -10- al quedar comunicadas las cámaras -2-2a-2b-2c- por el retroceso de unos medios separadores -5-5a- y el émbolo -4- arrastradas por el vástago -3-. El movimiento de los medios separados -5-5a- y del émbolo -4- es posible por la compresion y descomprension durante la manipulacion de la unidad mezcladora, de los gases inertes que se encuentran en el interior de cada uno de los compartimientos o cámaras -2-2a-2b-2c- que contienen los inyectables. Estos gases deben ser químicamente inertes para no alterar los inyectables contenidos. Tanto el extremo de inyeccion -1a- como el extremo de comando -1d- disponen de respectivos tapones -9-6- de cierre. En el caso del extremo de comando -1d-, el conducto central del tapon elastomérico está obturado herméticamente por la porcion del vástago -3- que se encuentra en su interior. Tiene las cubiertas -6a-7c- y medios de traba -7-3a- que inmovilizan el vástago -3- hasta que el mismo es activado para su funcionamiento.This unit has chambers -2-2a-2b-2c- of different cross-section, consecutively arranged from smaller -2- to greater -2a-2b-2c- from the injection end -1a- and inside which there are two substances -10a-10b-10c-10d- which are mixed -10- when the chambers -2-2a-2b-2c- are communicated by the withdrawal of separating means -5-5a- and the piston -4- dragged by the stem -3-. The movement of the separated means -5-5a- and the piston -4- is possible by the compression and decompression during the handling of the mixing unit, of the inert gases that are inside each of the compartments or chambers -2-2a-2b-2c- containing injectables. These gases must be chemically inert so as not to alter the injectable contents. Both the injection end -1a- and the command end -1d- have respective stoppers -9-6-. In the case of the command end -1d-, the central duct of the elastomeric plug is hermetically sealed by the portion of the rod -3- which is inside. It has the covers -6a-7c- and locking means -7-3a- that immobilize the rod -3- until it is activated for its operation.
