Description

SISTEMA REGULADOR DE PRESIÓN NEGATIVA EN LA EXTRACCIÓN DE SANGREREGULATORY SYSTEM OF NEGATIVE PRESSURE IN BLOOD EXTRACTION
OBJ ETO DE LA INVENCIÓN OBJECT OF THE INVENTION
Uno de los sistemas que más se utiliza en la actualidad en la extracción de sangre es el sistema de tubos de ensayos con presión negativa. Esta presión negativa puede provocar la saturación y/o obstrucción de la vena, con consecuencias negativas para el paciente; como puede ser la imposibilidad de extracción de sangre o rotura de la vena como consecuencia de dicha presión. One of the most commonly used systems in blood collection is the test tube system with negative pressure. This negative pressure can cause saturation and / or obstruction of the vein, with negative consequences for the patient; such as the impossibility of blood collection or rupture of the vein as a result of said pressure.
Para evitar esta problemática, que es provocada por la presión negativa continua, se debe de regular dicha presión de forma que esta no sea tan negativa y que en definitiva se consiga la extracción de sangre, atendiendo especialmente a la salud del paciente. To avoid this problem, which is caused by continuous negative pressure, this pressure must be regulated so that it is not so negative and that the blood draw is ultimately achieved, paying special attention to the patient's health.
El objeto de esta invención regula dicha presión negativa, a través de un reductor o sistema regulador, que dependiendo de la necesidad del paciente o usuario, el profesional sanitario puede abrir o cerrar dejando pasar el flujo necesario. De esta forma conseguimos dos ventajas importantes; primero que no pase toda la presión negativa directamente a la vena y segundo nos aseguramos de la eliminación de la obstrucción en la vena o en el peor de los casos rotura de la misma. The object of this invention regulates said negative pressure, through a reducer or regulating system, which depending on the need of the patient or user, the healthcare professional can open or close by allowing the necessary flow to pass. In this way we get two important advantages; First, do not pass all the negative pressure directly to the vein, and second, we ensure the removal of the obstruction in the vein or, in the worst case, rupture of the vein.
ANTECEDENTE DE LA INVENCIÓN Los sistemas de extracción actuales se componen principalmente de jeringa y un sistema de tubos de ensayos de presión negativa. BACKGROUND OF THE INVENTION Current extraction systems are mainly composed of syringes and a negative pressure test tube system.
El primer dispositivo para la extracción fue la jeringa; dentro de sus múltiples formas, tamaños y capacidades, donde la aplicación de la presión negativa es irregular, debido que dicha presión negativa se realiza a través del propio personal sanitario y se realiza adecuadamente en función de la experiencia o profesional i dad. En el caso del sistema del tubo de ensayo con presión negativa provoca una presión negativa continúa y esta no es regulable. Si lo que estamos buscando es una extracción de sangre de manera más segura, las ventajas e inconvenientes de ambos sistemas podría ser paliados si en ambos métodos de extracción fuese de una presión continua negativa regulable y/o controlable, que hasta ahora no ha existe. The first device for extraction was the syringe; within its multiple forms, sizes and capacities, where the application of negative pressure is irregular, because said negative pressure is carried out by the health personnel themselves and is properly carried out based on experience or professionalism. In the case of the test tube system with negative pressure it causes a continuous negative pressure and this is not adjustable. If what we are looking for is a safer blood collection, the advantages and disadvantages of both systems could be mitigated if in both methods of extraction it was a continuous negative pressure adjustable and / or controllable, which until now does not exist.
LO novedoso de esta patente es que el sistema de tubos de ensayos con presión negativa continua se puede controlar con este sistema regulador de tal forma, que la presión negativa sea regulable y/o controlable. The novelty of this patent is that the test tube system with continuous negative pressure can be controlled with this regulator system in such a way that the negative pressure is adjustable and / or controllable.
DESCRIPCIÓN DETALLADA DE UN EJEMPLO DE EJECUCIÓN DE LA INVENCIÓN DETAILED DESCRIPTION OF AN EXECUTION EXECUTION OF THE INVENTION
Este sistema regulador de presión negativa debe ser colocado en el sistema de tubos de ensayos de presión negativa o vacío 13 , entre el tubo flexible conductor del fluido sanguíneo que conecta el tubo de ensayo con presión negativa 14 y la aguja biselada que es lo que se conecta a la vena 12 . er Figura 1. This negative pressure regulator system must be placed in the negative or vacuum pressure test tube system 13, between the conductive flexible tube of the blood fluid that connects the test tube with negative pressure 14 and the beveled needle which is what is connect to vein 12. Figure 1.
Este nuevo sistema regula la presión de la siguiente forma: una vez conectada la vena con la aguja biselada 12 se conecta el tubo de ensayo con la presión negativa 14 , pasando toda la presión negativa por aguja a la vena. Esta presión negativa puede producir una obstrucción por presión negativa y/o en el peor de los casos rotura de la vena. This new system regulates the pressure in the following way: once the vein is connected with the beveled needle 12, the test tube is connected with the negative pressure 14, passing all the negative pressure through the needle to the vein. This negative pressure can produce a negative pressure obstruction and / or in the worst case vein rupture.
Entre la aguja 12 y el tubo con presión negativa 14 se coloca este sistema de regulación de presión negativa 13 , que estará conectado a través de los tubos 15 y 16. El objeto de esta regulación es evitar que la presión negativa entre directamente en vena y se controle para facilitar la extracción sanguínea. Between the needle 12 and the negative pressure tube 14, this negative pressure regulation system 13 is placed, which will be connected through the tubes 15 and 16. The purpose of this regulation is to prevent the negative pressure from directly entering the vein and It is controlled to facilitate blood collection.
El sistema regulador de la presión negativa deberá de estar en posición cero, es decir la apertura de la membrana 5 no deberá de coincidir con los agujeros de la membrana 4 , no dejando pasar ninguna fluido. Según la necesidad del profesional y fisiología del paciente, se procederá a abrir con las pestañas 8 y 9 que deben ser girados en sentido opuestos para proceder a la apertura de las membranas 4 y 5 dejando pasar la presión negativa o fluido necesario. Este giro provoca que la apertura de la membrana 4 que coincide con los distintos agujeros de la membrana 5 de forma que a mayor presión coincida con la mayor apertura de la ventana con los orificio. La entrada de fluido sanguíneo entra a través de la aguja biselada 12 que al recorrer por el tubo 15 pasa a la pieza 1 por la entrada 10 del s stema regulador, una vez que entra el fluido contacta con la membrana 4 que dependiendo si la apertura de la ventana o puerta coinciden con los orificios de la membrana 5, este deja pasar fluido o no. Para una mayor o menor presión negativa se procede a la apertura o cierre de la membrana 4. The negative pressure regulating system must be in the zero position, that is, the opening of the membrane 5 must not coincide with the holes in the membrane 4, not allowing any fluid to pass through. According to the need of the professional and physiology of the patient, it will proceed to open with tabs 8 and 9 that must be turned in opposite directions to proceed to the opening of membranes 4 and 5 allowing the necessary negative pressure or fluid to pass. This rotation causes the opening of the membrane 4 that coincides with the different holes of the membrane 5 so that at higher pressure it coincides with the greater opening of the window with the holes. The blood fluid inlet enters through the beveled needle 12 which, as it travels through the tube 15, passes to the piece 1 through the inlet 10 of the regulating system, once the fluid enters it contacts the membrane 4 which depending on whether the opening of the window or door coincide with the holes of the membrane 5, this allows fluid to pass or not. For a greater or lesser negative pressure, the membrane is opened or closed 4.
Una vez que ha pasado por el /los orificios de la membrana 5 este pasa por el cuerpo 7 y la salida 11 que conecta con el tubo 16 que se acopla con el tubo de ensayo de presión negativa 14. Once it has passed through the hole (s) of the membrane 5, it passes through the body 7 and the outlet 11 that connects with the tube 16 that is coupled with the negative pressure test tube 14.
Todo el sistema está diseñado para que sea estanco y pueda unirse gracias al elemento 2, 3, 4, 5, 6 y las piezas 1 y 7 formando un cuerpo único. The entire system is designed to be tight and can be joined thanks to element 2, 3, 4, 5, 6 and parts 1 and 7 forming a unique body.
