MEMORIA DESCRIPTIVA OBJETO DE LA INVENCIÓN DESCRIPTIVE MEMORY OBJECT OF THE INVENTION
La presente solicitud de Modelo de Utilidad tiene por objeto el registro de un dosificador portátil que incorpora notables innovaciones y ventajas. Más concretamente, la invención propone el desarrollo de un dosificador portátil para el llenado o recarga de jeringas de gran volumen de una forma simple y práctica en cualquier lugar.

More specifically, the invention proposes the development of a portable dispenser for filling or refilling large volume syringes in a simple and practical way anywhere.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
En la actualidad una gran mayoría de las operaciones de manipulación de fármacos citostáticos se realizan de forma manual, es decir, el enfermero o persona encargada de ello realiza la carga de jeringas de gran volumen (se entiende por gran volumen aquellas con una capacidad de 50ml o 60ml aproximadamente) de forma manual estirando con fuerza el émbolo de la jeringa hasta la dosis necesaria de llenado. Posteriormente, para realizar el vaciado del contenido o fármaco de la jeringa, el operario debe aplicar una mayor fuerza de presión para empujar el émbolo hacia dentro del recipiente. Esta fuerza aplicada para rellenar y vaciar puntualmente no implica ningún problema relevante, sin embargo, si esta operación debe ser realiza de una forma periódica y con una frecuencia considerable puede provocar lesiones en la región de la mano, tal como tendinitis. At present, a large majority of cytostatic drug handling operations are performed manually, that is, the nurse or person in charge of it performs the loading of large-volume syringes (large volume means those with a 50ml capacity or approximately 60ml) manually by forcefully stretching the syringe plunger to the necessary filling dose. Subsequently, to empty the contents or drug of the syringe, the operator must apply a greater pressure force to push the plunger into the container. This force applied to fill and empty punctually does not imply any relevant problem, however, if this operation must be performed periodically and with considerable frequency it can cause injuries in the region of the hand, such as tendinitis.
Con la finalidad de solventar el problema anteriormente planteado, se han desarrollado máquinas de gran tamaño para la recarga de jeringas de una forma automática, así como el empleo de unos medios de manipulación, tal como pinzas de agarre, las cuales deben ubicarse de una forma fijada dentro de un área de trabajo cerrada, en particular dentro de una campana de flujo laminar, por lo que no existe posibilidad de llevar a cabo la manipulación de la jeringa fuera de dicha zona de trabajo. Otro inconveniente detectado en estas máquinas conocidas es la necesidad de utilizar un material fungible o equipo de perfusión adicional para el correcto funcionamiento de estas máquinas, por lo que los costes de inversión y mantenimiento se incrementan. DESCRIPCIÓN DE LA INVENCIÓN In order to solve the problem outlined above, large machines have been developed for refilling syringes automatically, as well as the use of handling means, such as grippers, which must be located in a way fixed within a closed work area, in particular within a laminar flow hood, so there is no possibility of carrying out the syringe manipulation outside said work zone. Another drawback detected in these known machines is the need to use a fungible material or additional perfusion equipment for the correct operation of these machines, whereby the investment and maintenance costs are increased.
