Description

CONECTOR GIRATORIO PARA VÍAS INTRAVENOSAS SWIVEL CONNECTOR FOR INTRAVENOUS LINE
DESCRIPCION DESCRIPTION
SECTOR DE LA TÉCNICA TECHNIQUE SECTOR
La presente invención se refiere a tubos, vías, catéteres y otros dispositivos médicos utilizados en la terapia intravenosa. Más en particular, se refiere a un conector para evitar que las vías giren sobre sí mismas y se enrollen causando una interrupción del flujo medicamentoso o sanguíneo. The present invention relates to tubes, lines, catheters and other medical devices used in intravenous therapy. More particularly, it refers to a connector to prevent the lines from twisting and coiling causing an interruption of drug or blood flow.
ESTADO DE LA TÉCNICA STATE OF THE TECHNIQUE
La terapia intravenosa viene utilizándose desde la década de 1950. Algunos sistemas utilizados para la terapia intravenosa incluyen un catéter corto insertado en la vena de un paciente conectado a un recipiente dispensador estéril a través de un tubo. El fluido se mide a una velocidad específica desde el recipiente dispensador hasta el paciente. A veces, sin embargo, el tubo puede enredarse, especialmente cuando el paciente se mueve para sentirse cómodo después de estar en una posición durante mucho tiempo. Intravenous therapy has been in use since the 1950s. Some systems used for intravenous therapy include a short catheter inserted into a patient's vein connected to a sterile dispensing container via tubing. Fluid is metered at a specific velocity from the dispensing container to the patient. Sometimes, however, the tube can become tangled, especially when the patient moves to get comfortable after being in one position for a long time.
El mismo problema se presenta cuando se extrae sangre de un paciente o donante. The same problem occurs when blood is drawn from a patient or donor.
Es deseable por tanto disponer de un sistema que impida torsión y el enredo de las vías. It is therefore desirable to have a system that prevents twisting and entanglement of the tracks.
RESUMEN DE LA INVENCIÓN SUMMARY OF THE INVENTION
La presente invención resuelve el problema técnico expuesto anteriormente gracias a un conector giratorio para vías de terapia intravenosa que permite un fácil ajuste giratorio de una línea intravenosa para administrar o extraer fluidos de un paciente. The present invention solves the technical problem stated above thanks to a rotary connector for intravenous therapy lines that allows easy rotary adjustment of an intravenous line to administer or withdraw fluids from a patient.
El conector comprende una zona central y un primer y segundo tramos de vía adaptados para conectarse a otros dos tramos preexistentes y que se usaran para introducir medicamentos, suero, plasma, etc. o para extraer sangre del paciente. Cada extremo distal de los dos tramos de vía está provisto de un conector, hembra y macho respectivamente. Conectando ambos tramos de vía, en la zona central del conector, se encuentran dos piezas de unión y un rodamiento o cojinete La primera pieza de unión abraza el primer tramo de vía y va insertada en el hueco interior del cojinete. La segunda pieza de unión va unida al segundo tramo de vía y a la parte externa del cojinete. Los dos tramos de vía dentro de la zona central del conector, pero el segundo tramo solo lo hace por el interior de la segunda pieza de unión, sin llegar a tocar el cojinete o extenderse por su hueco interior. Así, el segundo tramo queda libre para girar alrededor del eje del conector. El conector asegura la estanqueidad y el paso ininterrumpido de los fluidos, además de reducir las probabilidades de que la vía se salga de la vena al eliminar las fuerzas de cizalla presentes cuando hay una torsión. The connector comprises a central area and a first and second sections of track adapted to connect to two other pre-existing sections and that will be used to introduce medications, serum, plasma, etc. or to draw blood from the patient. Each distal end of the two track sections is provided with a connector, female and male respectively. Connecting both sections of track, in the central area of the connector, there are two connecting pieces and a bearing or bearing. The first connecting piece embraces the first section of track and is inserted into the interior cavity of the bearing. The second connecting piece is attached to the second section of track and to the external part of the bearing. The two sections of track are inside the central area of the connector, but the second section only does so inside the second connecting piece, without touching the bearing or extending through its interior gap. Thus, the second section is free to rotate around the axis of the connector. The connector ensures tightness and uninterrupted passage of fluids, in addition to reducing the chances of the line coming out of the vein by eliminating the shear forces present when there is a twist.
BREVE DESCRIPCIÓN DE LAS FIGURAS BRIEF DESCRIPTION OF THE FIGURES
Con objeto de ayudar a una mejor comprensión de las características de la invención y para complementar esta descripción, se acompañan como parte integrante de la misma las siguientes figuras, cuyo carácter es ilustrativo y no limitativo: In order to help a better understanding of the characteristics of the invention and to complement this description, the following figures are attached as an integral part of it, the nature of which is illustrative and not limiting:
La figura 1 muestra un corte transversal del conector según el presente modelo de utilidad. Figure 1 shows a cross section of the connector according to the present utility model.
DESCRIPCIÓN DETALLADA DETAILED DESCRIPTION
La presente invención permite el uso de vías intravenosas sin que éstas se tuerzan, doblen o enreden. The present invention allows the use of intravenous lines without them becoming twisted, bent or tangled.
En referencia a la figura 1, el conector del presente modelo de utilidad comprende un primer 1 y segundo tramo de vía 2 con sendos conectores hembra y macho en cada extremo distal 1a, 2a correspondiente. Ambos tramos de vía son de igual diámetro y se sitúan en el eje principal del conector giratorio de la invención. A cada conector hembra y macho de los extremos se conectan los tramos de una vía preexistente para proporcionar medicamentos, para extraer sangre, etc. Referring to Figure 1, the connector of the present utility model comprises a first 1 and second section of track 2 with female and male connectors at each corresponding distal end 1a, 2a. Both sections of track are of equal diameter and are located on the main axis of the rotating connector of the invention. To each Female and male connector at the ends connect the sections of a pre-existing line to provide medications, to extract blood, etc.
Unidas a ambos tramos se encuentran dos piezas de unión 3, 4 y un rodamiento o cojinete 5 estanco (como entenderá un experto, un rodamiento es un tipo particular de cojinete provisto de esferas, en la figura se muestra una puesta en práctica particular con un rodamiento cuyas esferas están selladas en el interior de los dos anillos). Las piezas de unión y el cojinete forman una zona central del conector giratorio. La primera pieza de unión 3 abraza el primer tramo de vía 1 y va insertada en el hueco interior del cojinete 5a. La segunda pieza de unión va unida al segundo tramo de vía y a la parte externa del cojinete 5b. Los tramos de vía primero y segundo 1 , 2, se extienden pues dentro de la zona central del conector giratorio a lo largo de su eje central, pero el primer tramo 1 solo dentro de la primera pieza de unión 3 y el segundo tramo 2 solo por el interior de la segunda pieza de unión 4, sin extenderse por el hueco interior del cojinete 5a. De esta manera, el segundo tramo de vía queda libre 2 para girar alrededor del eje del conector (o viceversa, el primer tramo 1 queda libre para girar en torno al segundo). El primer tramo de vía 1 se extiende a lo largo del eje de la primera pieza de unión 3 de manera que su extremo queda muy próximo al extremo del segundo tramo de vía 2. Se asegura así la estanqueidad del conector y el paso ininterrumpido de los fluidos. Ambas piezas de unión y los tramos de vía están realizados preferentemente en plástico termoestable de uso médico, siendo las piezas de unión de un plástico rígido y los tramos de vía de un plástico flexible, mientras que el cojinete es preferentemente de acero. Attached to both sections are two connecting pieces 3, 4 and a sealed bearing or bearing 5 (as an expert will understand, a bearing is a particular type of bearing provided with spheres, the figure shows a particular implementation with a bearing whose spheres are sealed inside the two rings). The connecting parts and the bearing form a central area of the rotating connector. The first connecting piece 3 embraces the first section of track 1 and is inserted into the interior cavity of the bearing 5a. The second connecting piece is attached to the second section of track and to the external part of the bearing 5b. The first and second track sections 1, 2 thus extend within the central area of the rotary connector along its central axis, but the first section 1 only within the first connecting piece 3 and the second section 2 only inside the second connecting piece 4, without extending through the interior gap of the bearing 5a. In this way, the second section of track is free 2 to rotate around the axis of the connector (or vice versa, the first section 1 is free to rotate around the second). The first section of track 1 extends along the axis of the first connecting piece 3 so that its end is very close to the end of the second section of track 2. This ensures the tightness of the connector and the uninterrupted passage of the fluids. Both connecting pieces and the track sections are preferably made of thermostable plastic for medical use, the connecting pieces being made of a rigid plastic and the track sections being made of a flexible plastic, while the bearing is preferably made of steel.
La invención es de especial utilidad en pediatría y medicina veterinaria, ya que los pacientes de estas áreas no pueden limitar sus movimientos respecto a la vía. The invention is especially useful in pediatrics and veterinary medicine, since patients in these areas cannot limit their movements with respect to the road.
