Description

Aguja hipodérmica.Hypodermic needle.

Object of the invention

La presente invención se refiere a una aguja hipodérmica, de las utilizadas para la aplicación de inyecciones intramusculares o intravenosas.The present invention relates to a needle hypodermic, of those used for the application of injections intramuscular or intravenous.

El objeto de la invención es conseguir una aguja "indolora", es decir que no produce dolor o daño sensitivamente apreciable en el usuario al atravesar su piel y otros tejidos que deba atravesar hasta llegar al punto de inyección.The object of the invention is to obtain a needle "painless", that is to say that it does not produce pain or damage sensibly appreciable in the user when crossing his skin and other tissues that must pass through until you reach the point of injection.

Background of the invention

Como es sabido las agujas hipodérmicas consisten en un cuerpo tubular, de reducido diámetro, rematado por uno de los extremos en un cabezal de acoplamiento a la correspondiente y complementaria jeringa, con su extremo libre cortado a bisel, constituyendo una punta de inserción hueca y altamente afilada, de manera que al introducirse en el cuerpo del usuario produce un corte anular, con arrastre de un diminuto cilindro de tejido, que es la causa de que se produzca un fuerte dolor, concretamente debido al rasgado del mismo.As is known hypodermic needles consist in a tubular body, of reduced diameter, topped by one of the ends in a coupling head to the corresponding and complementary syringe, with its free end cut to bevel, constituting a hollow and highly sharp insertion point, of so that when introduced into the user's body produces a annular cut, with drag of a tiny tissue cylinder, which it is the cause of strong pain, specifically due to tear it.

Con independencia de que dicho dolor hace que muchos pacientes tengan aversión a las inyecciones, especialmente individuos de corta edad, el mencionado desgarro de los tejidos trae consigo en muchas ocasiones hematomas molestos y desagradables.Regardless of the fact that such pain causes many patients dislike injections, especially young individuals, the aforementioned tissue tearing it often brings annoying bruising and nasty

Description of the invention

La aguja hipodérmica que la invención propone resuelve de forma plenamente satisfactoria esta problemática, eliminado por completo el dolor debido al "pinchazo", por cuanto que no produce desgarro en los tejidos.The hypodermic needle that the invention proposes solves this problem fully satisfactorily, completely eliminated pain due to "prick", by since it does not produce tear in the tissues.

Para ello y de forma mas concreta la aguja que se preconiza, a partir de un cuerpo tubular similar al de una aguja hipodérmica convencional, centra sus características en el hecho de que su extremidad libre se remata, en lugar de un bisel cortante, en una punta cónica y maciza, de vértice afilado, que por su propia configuración no produce ningún efecto de corte sobre el tejido, como anteriormente se ha dicho, sino una simple deformación elástica del mismo alrededor de un imaginario eje, de fácil recuperación tras la extracción de la aguja.To do this and more specifically the needle that it is recommended, from a tubular body similar to that of a needle Conventional hypodermic, focuses its characteristics on the fact that its free limb is finished off, instead of a sharp bevel, on a conical and solid tip, with a sharp vertex, which by its own configuration does not produce any cutting effect on the tissue, as previously stated, but a simple deformation elastic around an imaginary axis, easy recovery after needle removal.

Como complemento de la estructura descrita y para la necesaria e ineludible salida de líquido, la citada punta cónica incorpora en su zona basal, varios agujeros laterales, de reducidas dimensiones, en comunicación directa con el cuerpo tubular, si bien y como es evidente tales orificios podrían estar igualmente situados en vez de en el citado cuerpo tubular, en las inmediaciones de la punta cónica.As a complement to the structure described and for the necessary and unavoidable liquid outlet, the mentioned tip Conical incorporates in its basal area, several lateral holes, of small dimensions, in direct communication with the body tubular, although and as is evident such holes could be also located instead of in the said tubular body, in the near the conical tip.

Preferred Embodiment of the Invention

A la vista de las figuras reseñadas puede observarse como la aguja que se preconiza está constituida a partir de un cuerpo tubular (1), de longitud y diámetro apropiados, preferentemente de acero, rematado por uno de sus extremos en el clásico cabezal (2) de acoplamiento a la complementaria jeringa, como anteriormente se ha dicho.In view of the figures outlined you can observe how the needle that is recommended is made from of a tubular body (1), of appropriate length and diameter, preferably of steel, topped by one of its ends in the classic head (2) coupling to the complementary syringe, as previously said.

Pues bien, de acuerdo ya con la invención el citado cuerpo tubular (1) incorpora en su extremo (3) opuesto al cabezal, una punta cónica y maciza (4), convenientemente afilada hacia su vértice (5) y con un diámetro en su base o extremidad interna coincidente con el diámetro externo del cuerpo tubular (1), como se observa en la figura 1ª.Well, according to the invention, the said tubular body (1) incorporates at its end (3) opposite the head, a conical and solid tip (4), conveniently sharp towards its vertex (5) and with a diameter at its base or limb internal coinciding with the external diameter of the tubular body (1), as seen in figure 1.

Para la fijación entre ambos elementos, cuerpo tubular (1) y punta cónica y maciza (4), ésta última puede incorporar un pequeño cuello anular (6) enchufable en la extremidad correspondiente del cuerpo tubular (1) y fijable a éste último por cualquier medio.For fixing between both elements, body tubular (1) and conical and solid tip (4), the latter can incorporate a small annular neck (6) pluggable into the limb corresponding to the tubular body (1) and attachable to the latter by any means

La punta cónica (4) presenta, emergiendo de su base (7) y dirigidos hacia su superficie lateral (8), una pluralidad de diminutos orificios pasantes (9), como se observa especialmente en el detalle de la figura 2, de manera que a través de estos orificios el líquido o producto farmacológico de que se trate sale de la aguja hacia la zona de inyección prevista.The conical tip (4) presents, emerging from its base (7) and directed towards its lateral surface (8), a plurality of tiny through holes (9), as noted especially in the detail of figure 2, so that through of these holes the liquid or drug product of which try leaving the needle towards the planned injection zone.

No obstante y como también se ha dicho con anterioridad, es factible que estos micro-orificios (9) en lugar de estar situados en la punta cónica (4), lo estén en la zona del cuerpo tubular (1) próxima a dicha punta.However, as has also been said with previously, it is feasible that these micro-holes (9) instead of being located on the conical tip (4), be in the area of the tubular body (1) next to said tip.

De esta manera se consigue que, frente a la huella (10) definida por una aguja hipodérmica convencional y mostrada en la figura 2, con una configuración anular y de apreciable diámetro, la huella que deja la aguja que se preconiza sea un simple punto (11), tal como es mostrado también en la figura 3, es decir una huella considerablemente mas pequeña y menos lesiva, que se produce en ausencia de dolor.This way you get that, in front of the fingerprint (10) defined by a conventional hypodermic needle and shown in figure 2, with an annular configuration and appreciable diameter, the imprint left by the needle that is recommended be a simple point (11), as also shown in the figure 3, that is to say a considerably smaller footprint and less harmful, which occurs in the absence of pain.
