OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La presente invención se refiere en general a instrumental auxiliar de cateterización para la inserción de un catéter en un vaso sanguíneo. The present invention relates generally to auxiliary catheterization instruments for inserting a catheter into a blood vessel.
De manera más concreta, la invención se refiere a un dispositivo aplicador de catéteres para la inserción de un catéter en un vaso sanguíneo, que tiene por objeto minimizar los riesgos de infección por flebitis o bacteriemia en asociada a la infección de catéteres, especialmente en catéteres venosos periféricos. More specifically, the invention relates to a catheter applicator device for inserting a catheter into a blood vessel, which aims to minimize the risks of infection by phlebitis or bacteremia associated with catheter infection, especially catheters. peripheral veins.
La invención también se refiere a un catéter que integra dicho dispositivo aplicador. ANTECEDENTES DE LA INVENCIÓN The invention also relates to a catheter that integrates said applicator device. BACKGROUND OF THE INVENTION
Las recomendaciones sobre inserción de un catéter son de aplicación universal con independencia del personal de enfermería o médico que inserte el catéter y con independencia del lugar donde se realiza el procedimiento. Actualmente, con el instrumental de cateterización existente, es necesario que el personal sanitario toque con sus dedos la zona proximal del catéter en el momento de realización de la técnica de inserción, pudiendo contaminar de ese modo el cuerpo del catéter. Recommendations on the insertion of a catheter are universally applicable regardless of the nursing staff or doctor who inserts the catheter and regardless of where the procedure is performed. Currently, with the existing catheterization instruments, it is necessary for the healthcare staff to touch the proximal catheter with their fingers at the time of the insertion technique, thereby contaminating the catheter body.
La bacteriemia asociada a catéter es una de las causas más frecuentes de infección adquirida en el ámbito hospitalario. La incidencia de bacteriemias asociadas a catéter por cada 1000 días de ingreso oscila entre 0,30 y 0,50 según diversas series publicadas. Un número no despreciable de esas bacteriemias se relacionan con catéteres venosos insertados en venas periféricas. Catheter-associated bacteraemia is one of the most frequent causes of infection acquired in the hospital setting. The incidence of catheter-associated bacteraemias per 1000 days of admission ranges between 0.30 and 0.50 according to various published series. A non-negligible number of these bacteraemias are related to venous catheters inserted in peripheral veins.
En el estado de la técnica son conocidos dispositivos auxiliares de canalización de catéter venoso periférico, destinados a la protección del personal sanitario, y otros que ayudan a optimizar el procedimiento mediante sistemas de fijación y estabilización de catéter 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 They help to optimize the procedure through catheter fixation and stabilization systems on the patient.
Sin embargo, no se conoce ningún sistema diseñado especialmente para disminuir la incidencia de bacteriemia y las infecciones asociadas a catéteres periféricos. However, no system specially designed to reduce the incidence of bacteraemia and infections associated with peripheral catheters is known.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
La presente invención soluciona las carencias anteriormente comentadas del estado de la técnica, proporcionando un aplicador para catéteres que permite llevar a cabo la técnica de inserción del catéter en un paciente, sin que sea necesario que los dedos del personal sanitario contacten en ningún momento con el catéter. The present invention solves the previously mentioned shortcomings of the state of the art, providing a catheter applicator that allows the technique of catheter insertion 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 invención se refiere a un aplicador de catéteres que comprende dos partes, una parte destinada a fijarse o acoplarse de forma fija a la base de un catéter genérico, y una segunda parte con una forma adecuada para que sea sujetada por los dedos de un usuario como personal de enfermería o médico. Estas dos partes están unidas entre sí mediante una unión desprendible, preferentemente dimensionada para que sea rompible o fracturable mediante acción manual, ya sea por torsión, flexión y/o tracción 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 such as nurses or doctors. 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 catéter en un vaso sanguíneo, 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 catéter convencional mediante la parte de fijación, por ejemplo mediante un acoplamiento a presión quedando ambas partes fijadas de forma estable, y sin que para ello sea necesario tocar el catéter en ningún momento. Thus, to insert a catheter into a blood vessel, the user holds with his fingers the applicator by the hand-grip part, and couples 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 catéter, se procede a la inserción del mismo en un vaso sanguíneo sosteniendo el conjunto solo por la parte de agarre, para lo cual la zona de unión está dimensionada para realizar la inserción 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 inserción del catéter y su conexión a un tapón, un conector sin aguja o a un sistema de infusión, el usuario procede a retirar la parte de agarre de manera manual rompiendo la zona de unión, simplemente flexionando, torsionando o traccionando la parte de agarre respecto a la parte de fijación, hasta producir la ruptura del material de la zona de unión. La parte de fijación permanece unida a la base del catéter, 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 cap, a needleless connector or an infusion system, the user proceeds to remove the grip part so manual breaking the joint area, simply by flexing, twisting or pulling the grip part with respect to the fixing part, until the material in the bonding zone 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 thereof.
Preferentemente, estas dos partes están unidas entre sí mediante una unión dimensionada para que sea rompible o fracturable mediante acción manual, ya sea por torsión, flexión y/o tracción entre las dos partes del aplicador. Preferably, these two parts are joined together by a joint sized to be breakable or fractured by manual action, either by twisting, bending and / or traction between the two parts of the applicator.
No obstante, la zona de unión entre la parte de fijación y la parte de agarre manual, se puede implementar de cualquier otra forma que permita la fácil separación entre ambas partes de forma manual. Otro aspecto de la invención se refiere a un catéter dotado convencionalmente de una base de catéter y una aguja insertada por uno de sus extremos en dicha base. El catéter de la invención se caracteriza porque además comprende un elemento aplicador que incluye una parte de agarre manual adecuada para ser sujetada por los dedos de un usuario, la cual está unida mediante una unión desprendible con la base del catéter, donde preferentemente dicha unión es rompible o fracturable mediante acción manual. However, the joining area between the fixing part and the manual gripping part can be implemented in any other way that allows easy separation between both parts manually. Another aspect of the invention relates to a catheter conventionally provided with a catheter base and a needle inserted by one of its ends in said base. The catheter of the invention is characterized in that it further comprises an applicator element that includes a hand grip part suitable for being held by the fingers of a user, which is joined by a removable joint with the base of the catheter, where preferably said joint is breakable or fractured by manual action.
