OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION

La presente invención se refiere a una sonda que ha sido especialmente concebida para el sondaje vesical, pero que es igualmente aplicable al sondaje de otras cavidades, tanto en seres humanos como en animales.The present invention relates to a probe that has been specially designed for bladder catheterization, but which is equally applicable to catheterization of other cavities, both in humans and animals.

El objeto de la invención es conseguir una sonda monopieza, dotada de medios limitadores de penetración adecuados a la utilización práctica prevista para la misma, evitando lesiones accidentales en la cavidad a drenar, sonda utilizable tanto en operaciones de drenaje como de toma de muestras, que permite obtener unos óptimos resultados incluso cuando es manipulada por personas inexpertas.The object of the invention is to achieve a single piece probe, equipped with penetration limiting means suitable for the practical use provided therein, avoiding accidental injuries in the drainage cavity, a probe that can be used both in drainage and sampling operations, which It allows to obtain optimal results even when it is manipulated by inexperienced people.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

Como es sabido, las sondas para cateterismo están constituidas mediante un cuerpo tubular de calibre o diámetro apropiado, a base de plástico, látex u otros materiales asimismo apropiados, que en el caso concreto de sondaje vesical son acordes al diámetro y longitud de la uretra, y cuyos parámetros varían en función de a qué tipo de cavidad corporal se pretende acceder. Específicamente la cota longitudinal está debidamente sobredimensionada para permitir la manipulación de la sonda en su fase terminal de implantación de la misma, lo que supone que la manipulación de la sonda deba ser efectuada por personas expertas para evitar una penetración insuficiente de la misma en la cavidad a drenar o a sondar, o una penetración excesiva que pudiera dar lugar a lesiones accidentales en dicha cavidad, riesgos que se mantienen, aunque debidamente minimizados, incluso cuando su manipulación se lleva a cabo por una persona experta.As it is known, catheterization probes are constituted by a tubular body of appropriate caliber or diameter, based on plastic, latex or other equally appropriate materials, which in the specific case of bladder catheterization are consistent with the diameter and length of the urethra, and whose parameters vary depending on what type of body cavity is intended to be accessed. Specifically, the longitudinal dimension is duly oversized to allow manipulation of the probe in its terminal phase of implantation, which means that the manipulation of the probe must be carried out by experts to avoid insufficient penetration of the probe into the cavity. to drain or probe, or excessive penetration that could lead to accidental injuries in said cavity, risks that are maintained, although duly minimized, even when their manipulation is carried out by an expert person.

DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION

La sonda que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, de manera que utilizando en cada caso una sonda de características especificas al respecto, la penetración de la sonda en la cavidad a drenar es la exacta, sin que se produzcan variaciones accidentales en dicha cota ni en sentido positivo ni en sentido negativo, incluso ante una total inexperiencia de la persona que la está manipulando, y eso en base a que dicha sonda incorpora una expansión intermedia a modo de globo, también hueco al igual que el resto de la sonda, que por un lado actúa como tope limitador de penetración para la misma, asegurando que dicha penetración es la correcta sin riesgo de lesiones accidentales en la cavidad de que se trate, que por otro lado constituye el medio de soporte y manejo de la sonda, que facilita la manipulación de la misma evitando la manipulación de extremo de dicha sonda que ha de ser introducido en la cavidad biológica, que consecuentemente facilita la manipulación de la sonda hacia delante o hacia atrás y los movimientos de rotación de la misma, incluso con una sola mano, y que finalmente constituye una cavidad en dicha sonda que permite que la misma pueda ser utilizada para recogida de muestras. Obviamente las dimensiones del tubo constitutivo de la sonda serán similares a las de cualquier sonda convencional, de acuerdo con la utilización específica prevista para la misma, el distanciamiento del globo intermedio con respecto al extremo distal de la sonda será variable en función del tipo de cavidad a evacuar y la distancia del conducto biológico a sondar, y por lo demás la sonda podrá estar lubricada o no lubricada, podrá ser coloreada en su material para una identificación más sencilla de su aplicación específica, y su punta será roma, con orificio terminal y/o con orificios laterales.The probe proposed by the invention solves in a fully satisfactory manner the above-mentioned problem, so that using in each case a probe with specific characteristics in this regard, the penetration of the probe into the drainage cavity is the exact one, without variations occurring. accidental in said dimension neither in a positive nor in a negative sense, even before a total inexperience of the person who is manipulating it, and that on the basis that said probe incorporates an intermediate expansion like a balloon, also hollow like the rest of the probe, which on the one hand acts as a penetration limit stop for it, ensuring that said penetration is correct without risk of accidental injury to the cavity in question, which on the other hand constitutes the support and handling means of the probe, which facilitates the manipulation thereof avoiding the end manipulation of said probe to be introduced into the biological cavity a, which consequently facilitates the manipulation of the probe forwards or backwards and the rotational movements thereof, even with only one hand, and which finally constitutes a cavity in said probe that allows it to be used for collecting samples. Obviously the dimensions of the tube constituting the probe will be similar to those of any conventional probe, according to the specific use provided for it, the distance between the intermediate balloon and the distal end of the probe will vary depending on the type of cavity to be evacuated and the distance of the biological conduit to be probed, and otherwise the probe may be lubricated or not lubricated, it may be colored in its material for a simpler identification of its specific application, and its tip will be blunt, with terminal hole and / or with side holes.
