La presente invención que se reivindica consiste en un modelo de utilidad, y se refiere a un dispositivo para evitar inoculaciones y punzadas accidentales durante el manejo de agujas hipodérmicas, aumentando por ello la seguridad laboral al reducir el riesgo de accidentes de los operadores sanitarios, veterinarios, analistas de laboratorio y todos aquellos agentes que manejan agujas hipodérmicas.  The present invention that is claimed is a utility model, and refers to a device to prevent inoculations and accidental punctures during the handling of hypodermic needles, thereby increasing occupational safety by reducing the risk of accidents of sanitary operators, veterinarians , laboratory analysts and all those agents that handle hypodermic needles.
Esto es de gran importancia ya que reduce el stress laboral así como los costes sociales y económicos que generan los accidentes.  This is of great importance since it reduces work stress as well as the social and economic costs that accidents generate.
Hoy en día la presión por los objetivos, la vida acelerada, hacen que la fatiga, la saturación, el stress laboral, propicien fallos de atención e incrementen el nivel potencial de riesgo de accidente incluso entre los profesionales más experimentados.  Nowadays the pressure for the objectives, the accelerated life, make fatigue, saturation, work stress, cause attention failures and increase the potential level of accident risk even among the most experienced professionals.
Es objetivo prioritario de la legislación laboral, mediante la prevención de riesgos, mejorar las condiciones de seguridad e higiene en el trabajo, a fin de minimizar la exposición a riesgos de los trabajadores.  It is a priority objective of labor legislation, through risk prevention, to improve the conditions of safety and hygiene at work, in order to minimize exposure to workers' risks.
Desde el punto de vista de operatividad y funcionalidad la invención que se reivindica mejora notablemente el manejo y el uso de las agujas hipodérmicas como ningún sistema hasta ahora lograba.  From the point of view of operability and functionality, the claimed invention greatly improves the handling and use of hypodermic needles as no system hitherto achieved.
La gran simplicidad del mismo, así como su tremenda eficacia y la importancia del problema que resuelve hace que su viabilidad económica e industrial sea plena, pudiéndose llegar a convertirse en un estándar normalizado en su sector. The great simplicity of it, as well as its tremendous effectiveness and the importance of the problem it solves, makes its economic and industrial viability full, being able to reach Become a standardized standard in your sector.
Los protectores de agujas hipodérmicas que se utilizan habitualmente, conllevan un alto riesgo a la hora de colocar la aguja dentro del protector pues presentan un orificio reducido por donde hay que introducir la aguja.  Hypodermic needle protectors that are commonly used, carry a high risk when placing the needle inside the protector because they have a small hole where the needle must be inserted.
Esta característica con lleva un riesgo de accidentes que han sido objeto de propuestas por parte de numerosos inventores, más o menos efectivas o viables como podemos hallar en el estado actual de la técnica.  This feature carries a risk of accidents that have been the subject of proposals by numerous inventors, more or less effective or viable as we can find in the current state of the art.

Por último encontramos el grupo de propuestas , entre otras, que proponen proteger los dedos de la aguja mediante un escudo protector. Unos proponen un anillo circular en la embocadura U 9000213, US 00 D330420S, US 5.092.852, otros diseñan capuchones con peana y una embocadura cónica US 00D353.194 para evitar tener que sujetar el capuchón con la mano.  Finally we find the group of proposals, among others, that propose to protect the fingers of the needle by means of a protective shield. Some propose a circular ring in the mouth U 9000213, US 00 D330420S, US 5,092,852, others design caps with base and a conical mouth US 00D353,194 to avoid having to hold the cap by hand.
Se trata de conseguir un sistema que reduzca los riesgos de pinchazos con agujas, que aumente la seguridad en el manejo y encapuchado y que sea compatible en la mayor medida con los procedimientos sanitarios e industriales vigentes para que no suponga un sobrecoste que impida su implementación y difusión.  It is about achieving a system that reduces the risks of needle sticks, that increases the safety in handling and hooded and that is compatible to the greatest extent with the sanitary and industrial procedures in force so that it does not imply an extra cost that prevents its implementation and diffusion.
De acuerdo con la invención, este objetivo se consigue mediante un protector de aguja de! tipo de cánula transparente que tiene unas dimensiones similares a los actuales pero que se diferencia en su embocadura coloreada y dentada y en un extremo abombado para su asidero alejado de la embocadura con lo cual las manos no quedan enfrentadas a la aguja cuando se reencapucha. Todos estos sistemas aunque son muy distintos tienen entre otros el común inconveniente a la hora de su manejo y es que a la hora de introducir la aguja en el capuchón lo hacen teniendo que "enfrentar ambas manos", siendo en ese instante cuando se pueden producir los accidentes. According to the invention, this objective is achieved by a needle guard of! type of transparent cannula that has similar dimensions to the current ones but that differs in its colored and toothed mouthpiece and at a domed end for its handle away from the mouthpiece whereby the hands do not face the needle when it is re-engaged. All these systems, although they are very different, have among others the common inconvenience at the time of their handling and it is that at the time of introducing the needle into the cap they do so having to "face both hands", being at that moment when they can occur the accidents.
Así mismo pecan de aparatosos, complejos, de difícil o que entorpecen el manejo de la jeringuilla y de la aguja.  Likewise, they sin of appalling, complex, difficult or that hinder the handling of the syringe and the needle.
No implican problemas de viabilidad industrial por sobrecoste ya que solamente hay que realizar un molde con la forma determinada.  They do not imply problems of industrial viability due to cost overruns since only a mold with the determined shape must be made.
Además facilita la localización de agujas y su procesamiento y reciclaje.  It also facilitates the location of needles and their processing and recycling.
El modelo de utilidad reivindicado consiste en un protector de agujas con las siguientes características: The claimed utility model consists of a needle guard with the following characteristics:
Presenta un extremo abierto con una embocadura tronco- piramidal (Fig 1-a), cuyo borde es dentado ( Fig 1-b) por toda la arista de la base mayor, siendo su función la servir de punto de apoyo y bloqueo lateral de la aguja; dicha embocadura está coloreada (Fig 1-c), opaca, en amarillo o naranja (colores de seguridad normalizados) definiendo y delimitando, por un marcado contraste figura-fondo, de manera muy clara, la embocadura del protector, destacando la aguja y el mismo, frente a la mayoría de ios colores de fondo en el ámbito hospitalario.  It has an open end with a trunk-pyramidal mouth (Fig 1-a), whose edge is serrated (Fig 1-b) along the edge of the main base, its function being to serve as a support point and lateral blockade of the needle; said mouthpiece is colored (Fig 1-c), opaque, in yellow or orange (standardized safety colors) defining and delimiting, by a marked contrast figure-bottom, very clearly, the mouthpiece of the protector, highlighting the needle and the same, compared to most of the background colors in the hospital setting.
El vástago o caña, transparente, que sirve de alojamiento a la aguja (Fig 1-d) presenta en su extremo cerrado, distal de la embocadura, un ensanchamiento ovoide (Fig 1-e), orientado longitudinalmente respecto del plano medio del protector, cuya función es servir de asidero y determinar el punto de sujeción del protector alejado de la embocadura , ofreciendo una superficie de agarre amplia.  The transparent rod or rod, which serves as a housing for the needle (Fig 1-d) has at its closed end, distal to the mouth, an ovoid widening (Fig 1-e), oriented longitudinally with respect to the median plane of the protector, whose function is to serve as a handle and determine the point of attachment of the protector away from the mouth, offering a wide grip surface.
La embocadura (Fig 2) presenta las siguientes especificidades: The mouthpiece (Fig 2) has the following specificities:
a) Su forma tronco-piramidal dota de estabilidad al protector cuando se deposita encima de una superficie. Frente a los sistemas que incorporan un escudo redondo, cónicos o de aberturas hexagonales que giran, rotan y se mueven con mucha facilidad al ser transportados en una bandeja esparciéndose y mezclándose con otro instrumental.  a) Its trunk-pyramidal shape provides stability to the protector when deposited on a surface. In front of the systems that incorporate a round shield, conical or of hexagonal openings that rotate, rotate and move very easily when being transported in a tray spreading and mixing with other instruments.
b) Sus dimensiones vienen determinadas en cuanto la altura y la anchura por requisitos específicos de la función que desempeñan, no son arbitrarios. La altura (Fig 2-A /a) será de 1/2 de la base plástica coloreada de la aguja (Fig 2 B) dejándola a la vista, así no se oculta el código de color de la misma. La anchura viene determinada por la longitud del lado del cuadrado de la base piramidal, midiendo 2 veces el diámetro de la base plástica de la aguja en su punto medio.  b) Their dimensions are determined as the height and width by specific requirements of the function they perform, are not arbitrary. The height (Fig 2-A / a) will be 1/2 of the colored plastic base of the needle (Fig 2 B) leaving it in sight, so the color code of the needle is not hidden. The width is determined by the length of the square side of the pyramidal base, measuring twice the diameter of the plastic base of the needle at its midpoint.
c) Está coloreada, opacaA en amarillo o naranja para generar un acusado contraste-fondo con respecto al acero de la aguja, su base de color, el resto del protector, y las superficies sobre las que deposite el mismo. d) La arista de la base mayor, presenta un borde dentado (Fig 2) en sus cuatros lados. Los dientes tendrán una separación y altura equivalente al diámetro de la aguja, con los cantos romos. Su función es la de permitir el apoyo y bloqueo lateral de la aguja posibilitando "el basculamiento del protector sobre la aguja". b) el extremo cerrado del protector incorpora un ensanchamiento ovalado (Fig 1-e) destinado a aumentar la superficie de agarre del protector y a establecer un punto fijo de agarre. Ello mejora y facilita notablemente la ergonomía del agarre evitando la hiperextensión del pulgar, o dedo en patín (patología muy común entre quien realiza sujeciones de objetos de reducido diámetro). Así 3mo ai deierminar un punto de agarre específico impide, a ia práctica habitual en los capuchones tradicionales de sujetarlos por la zona más próxima a la embocadura ya que esta es la más ancha y la que permite una mejor sujeción con io que el riesgo de accidente se vé muy acrecentado por la proximidad de los dedos a la embocadura. " Con el diseño reivindicado esto se evita completamente". c) It is colored, opaque A in yellow or orange to generate a sharp contrast-background with respect to the steel of the needle, its color base, the rest of the protector, and the surfaces on which it deposits. d) The edge of the main base has a serrated edge (Fig 2) on its four sides. The teeth will have a separation and height equivalent to the diameter of the needle, with blunt edges. Its function is to allow the support and lateral blocking of the needle allowing "the swinging of the protector on the needle". b) the closed end of the protector incorporates an oval widening (Fig 1-e) intended to increase the grip surface of the protector and establish a fixed point of grip. This significantly improves and facilitates the ergonomics of the grip avoiding the hyperextension of the thumb, or toe in skate (very common pathology among those who hold fasteners of small diameter objects). Thus, to determine a specific grip point, it prevents the usual practice in traditional caps from holding them by the area closest to the mouth since this is the widest and the one that allows a better grip with it than the risk of accident It is greatly enhanced by the proximity of the fingers to the mouth. "With the claimed design this is completely avoided."
Estas características del diseño y forma del protector son determinantes y esenciales para la función que desempeña, posibilitando que un nuevo manejo, totalmente distinto más sencillo y con apenas riesgo de punciones. These characteristics of the design and shape of the protector are decisive and essential for the function it performs, allowing a new, totally different handling, easier and with little risk of punctures.
