La presente invention se refiere en general a instrumental auxiliar de cateterizacion para la insertion de un cateter en un vaso sangumeo.The present invention relates generally to auxiliary catheterization instruments for insertion of a catheter into a blood vessel.

De manera mas concreta, la invencion se refiere a un dispositivo aplicador de cateteres para la insercion de un cateter en un vaso sangumeo, que tiene por objeto minimizar los riesgos de infeccion por flebitis o bacteriemia en asociada a la infeccion de cateteres, especialmente en cateteres venosos perifericos.More specifically, the invention relates to a catheter applicator device for insertion of a catheter into a blood vessel, which aims to minimize the risks of infection by phlebitis or bacteremia associated with catheter infection, especially in catheters. peripheral veins.

La invencion tambien se refiere a un cateter que integra dicho dispositivo aplicador. ANTECEDENTES DE LA INVENCIONThe invention also relates to a catheter that integrates said applicator device. BACKGROUND OF THE INVENTION

Las recomendaciones sobre insercion de un cateter son de aplicacion universal con independencia del personal de enfermeria o medico que inserte el cateter y con independencia del lugar donde se realiza el procedimiento. Actualmente, con el instrumental de cateterizacion existente, es necesario que el personal sanitario toque con sus dedos la zona proximal del cateter en el momento de realization de la tecnica de insercion, pudiendo contaminar de ese modo el cuerpo del cateter.The recommendations on insertion of a catheter are universally applicable regardless of the nursing or medical staff that inserts the catheter and regardless of where the procedure is performed. Currently, with the existing catheterization instruments, it is necessary for the healthcare personnel to touch the proximal catheter with their fingers at the time of insertion technique, thus being able to contaminate the catheter's body.

La bacteriemia asociada a cateter es una de las causas mas frecuentes de infection adquirida en el ambito hospitalario. La incidencia de bacteriemias asociadas a cateter por cada 1000 dias de ingreso oscila entre 0,30 y 0,50 segun diversas series publicadas. Un numero no despreciable de esas bacteriemias se relacionan con cateteres venosos insertados en venas perifericas.Catheter-associated bacteraemia is one of the most frequent causes of infection acquired in the hospital setting. The incidence of bacteremia associated with catheter per 1000 days of admission ranges between 0.30 and 0.50 according to various published series. A non-negligible number of these bacteremia are related to venous catheters inserted in peripheral veins.

En el estado de la tecnica son conocidos dispositivos auxiliares de canalization de cateter venoso periferico, destinados a la proteccion del personal sanitario, y otros que ayudan a optimizar el procedimiento mediante sistemas de fijacion y estabilizacion de cateter sobre el paciente.Auxiliary peripheral venous catheter channeling devices are known in the state of the art, intended for the protection of health personnel, and others that help optimize the procedure by means of catheter fixation and stabilization systems on the patient.

Sin embargo, no se conoce ningun sistema disenado especialmente para disminuir la incidencia de bacteriemia y las infecciones asociadas a cateteres perifericos.However, no system specially designed to reduce the incidence of bacteraemia and infections associated with peripheral catheters is known.

DESCRIPCION DE LA INVENCIONDESCRIPTION OF THE INVENTION

La presente invention soluciona las carencias anteriormente comentadas del estado de la tecnica, proporcionando un aplicador para cateteres que permite llevar a cabo la tecnica de insertion del cateter en un paciente, sin que sea necesario que los dedos del personal sanitario contacten en ningun momento con el cateter.The present invention solves the previously mentioned shortcomings of the state of the art, providing an applicator for catheters that allows the catheter insertion technique to be carried out in a patient, without it being necessary for the fingers of the healthcare staff to contact at any time with the catheter.

Para ello, un primer aspecto de la invencion se refiere a un aplicador de cateteres que comprende dos partes, una parte destinada a fijarse o acoplarse de forma fija a la base de un cateter generico, y una segunda parte con una forma adecuada para que sea sujetada por los dedos de un usuario como personal de enfermeria o medico. Estas dos partes estan unidas entre si mediante una union desprendible, preferentemente dimensionada para que sea rompible o fracturable mediante action manual, ya sea por torsion, flexion y/o traction entre las dos partes del aplicador.For this, a first aspect of the invention relates to a catheter applicator comprising two parts, a part intended to be fixed or fixedly attached to the base of a generic catheter, and a second part with a suitable shape to be held by the fingers of a user as nurses or doctor. These two parts are joined together by a removable joint, preferably sized to be breakable or fractured by manual action, either by twisting, bending and / or traction between the two parts of the applicator.

De este modo, para insertar un cateter en un vaso sangumeo, el usuario sostiene con sus dedos el aplicador por la parte de agarre manual, y lo acopla a la parte proximal (o base) de un cateter convencional mediante la parte de fijacion, por ejemplo mediante un acoplamiento a presion quedando ambas partes fijadas de forma estable, y sin que para ello sea necesario tocar el cateter en ningun momento.Thus, to insert a catheter into a blood vessel, the user holds with his fingers the applicator by the hand-grip part, and attaches it to the proximal part (or base) of a conventional catheter by means of the fixation part, by for example, by means of a pressure coupling, both parts being stably fixed, and without it being necessary to touch the catheter at any time.

Una vez acoplado el aplicador al cateter, se procede a la insercion del mismo en un vaso sangumeo sosteniendo el conjunto solo por la parte de agarre, para lo cual la zona de union esta dimensionada para realizar la insercion manteniendo el conjunto estable.Once the applicator is attached to the catheter, it is inserted into a blood vessel holding the assembly only by the grip part, for which the joint area is sized to perform the insertion keeping the assembly stable.

Tras la correcta insercion del cateter y su conexion a un tapon, un conector sin aguja o a un sistema de infusion, el usuario procede a retirar la parte de agarre de manera manual rompiendo la zona de union, simplemente flexionando, torsionando o traccionando la parte de agarre respecto a la parte de fijacion, hasta producir la ruptura del material de la zona de union. La parte de fijacion permanece unida a la base del cateter, sin que ello suponga una molestia para el paciente o inconveniente en el posterior uso del mismo.After the correct insertion of the catheter and its connection to a plug, a needleless connector or an infusion system, the user proceeds to remove the grip part manually by breaking the joint area, simply by flexing, twisting or pulling the part of grip with respect to the fixing part, until the material in the joining area ruptures. The fixation part remains attached to the base of the catheter, without this causing discomfort to the patient or inconvenience in the subsequent use of the same.

Preferentemente, estas dos partes estan unidas entre si mediante una union dimensionadaPreferably, these two parts are joined together by a dimensioned joint
