Abstract

Disclosed is an infiltration syringe that allows an aspiration movement to be performed before infiltrating, without needing to hold the syringe with the other hand. This is made possible because the syringe has first flaps (6) that act as a support during injection, and second flaps (7) used during aspiration, both sets of flaps being parallel to each other. The syringe also comprises large flanges (9) disposed at one end of a plunger (1).

Description

DESCRIPCIÓN DESCRIPTION
Jeringa de infiltraciones SECTOR DE LA TÉCNICA Infiltration syringe TECHNICAL SECTOR
La presente invención se refiere a una jeringa de infiltraciones, especialmente adaptada para realizar fácilmente una aspiración antes de la infiltración. Es de aplicación en el campo médico y veterinario. The present invention relates to an infiltration syringe, specially adapted to easily carry out an aspiration before infiltration. It is applicable in the medical and veterinary field.
ESTADO DE LA TÉCNICA STATE OF THE ART
Cuando se realiza una infiltración, facial o corporal, es conveniente realizar una pequeña aspiración antes de inyectar para confirmar que no se vaya a realizar dentro de un vaso sanguíneo. Hay que considerar que si el producto se inyecta en el torrente sanguíneo se distribuye por todo el cuerpo y deja de hacer efecto. En algunos casos, incluso puede producir algún efecto secundario indeseado. When an infiltration is carried out, facial or corporal, it is advisable to carry out a small aspiration before injecting to confirm that it is not going to be carried out into a blood vessel. It must be borne in mind that if the product is injected into the bloodstream, it is distributed throughout the body and stops working. In some cases, it can even produce some unwanted side effect.
El solicitante no conoce ninguna solución a estos problemas igual de eficaz que la reivindicada. The applicant does not know of any solution to these problems as effective as the one claimed.
BREVE EXPLICACIÓN DE LA INVENCIÓN BRIEF EXPLANATION OF THE INVENTION
La invención consiste en una jeringa según la reivindicación independiente. The invention consists of a syringe according to the independent claim.
Su principal ventaja es que permite realizar un movimiento de aspiración antes de infiltrar el producto sin necesidad de ayudarse o mantener la jeringa con la otra mano. Por lo tanto, el médico o técnico sanitario puede utilizar la otra para otras tareas, como disponer un algodón con producto antiséptico para aplicar en el punto de punción. Además, facilita la maniobra de aspiración previa a la infiltración y evita el balanceo de la aguja en el interior del paciente aportando seguridad, no sólo al médico, sino a la persona a la que se le aplica el tratamiento. Its main advantage is that it allows an aspiration movement before infiltrating the product without the need to help or hold the syringe with the other hand. Therefore, the doctor or health technician can use the other for other tasks, such as placing a cotton ball with an antiseptic product to apply to the puncture site. In addition, it facilitates the aspiration maneuver prior to infiltration and avoids the rocking of the needle inside the patient, providing security, not only for the doctor, but also for the person to whom the treatment is applied.
La jeringa de infiltraciones es del tipo que comprende un émbolo con un asa (2) y una carcasa tubular por la que desliza el émbolo. La carcasa está rematada en una conexión para aguja. El émbolo se introduce en la carcasa por una boca de ésta. La carcasa posee unas primeras solapas próximas a la boca (generalmente alineadas con éste), Además comprende unas segundas solapas más distantes a la boca que las primeras solapas. The infiltration syringe is of the type that comprises a plunger with a handle (2) and a tubular casing through which the plunger slides. The housing is finished with a needle connection. The plunger is inserted into the housing through a mouth of the latter. The carcass has first flaps close to the mouth (generally aligned with it), It also comprises second flaps more distant from the mouth than the first flaps.
Preferiblemente, las solapas están en un mismo plano longitudinal a la carcasa. Así es posible apoyar la jeringa sobre una superficie plana sin que ocupe demasiado volumen.Preferably, the flaps are in the same longitudinal plane to the carcass. This makes it possible to rest the syringe on a flat surface without taking up too much volume.
Más preferiblemente, las solapas están integradas en un único cuerpo fijado a la carcasa o fabricado íntegro con ésta. More preferably, the flaps are integrated into a single body fixed to or integrally manufactured therewith.
Por su parte, se prefiere que el asa está formada por alerones de al menos 3 cm de longitud total (1,5 cm a cada lado), preferiblemente 4,2 cm. For its part, it is preferred that the handle is formed by flaps of at least 3 cm in total length (1.5 cm on each side), preferably 4.2 cm.
Como ejemplo, las primeras solapas serán de un tamaño similar a los alerones, las segunda solapas serán algo menores y la distancia entre solapas será de, por ejemplo, 1 ,5 cm. As an example, the first flaps will be of a similar size to the ailerons, the second flaps will be somewhat smaller and the distance between flaps will be, for example, 1.5 cm.
Otras soluciones particulares se incluyen en las reivindicaciones dependientes y se describen en detalle más adelante. Other particular solutions are included in the dependent claims and are described in detail below.

MODOS DE REALIZACIÓN DE LA INVENCIÓN MODES OF EMBODIMENT OF THE INVENTION
A continuación, se pasa a describir de manera breve un modo de realización de la invención, como ejemplo ilustrativo y no limitativo de ésta. An embodiment of the invention will be briefly described below, as an illustrative and non-limiting example thereof.
La realización de la figura 1 corresponde a un ejemplo de jeringa del tipo aplicado para infiltrar ácido hialurónico. El producto exacto que se infiltre es irrelevante, al igual que las dimensiones o materiales de la jeringa. The embodiment of figure 1 corresponds to an example of a syringe of the type applied to infiltrate hyaluronic acid. The exact product that is infiltrated is irrelevant, as is the dimensions or materials of the syringe.
La jeringa comprende un émbolo (1) rematado en un asa (2) y una carcasa (3) rematada en una conexión para una aguja (no representada), preferiblemente del tipo “luerlock”. La conexión para la aguja puede comprender un tapón (4), generalmente de material elástico como silicona, látex o caucho. La carcasa (3) posee en la boca (5) de entrada del émbolo (1) unas primeras solapasThe syringe comprises a plunger (1) finished in a handle (2) and a housing (3) finished in a connection for a needle (not shown), preferably of the "luerlock" type. The connection for the needle can comprise a plug (4), generally made of elastic material such as silicone, latex or rubber. The casing (3) has first flaps in the inlet (5) of the plunger (1)
(6) que sirven de apoyo durante la inyección. Además posee unas segundas solapas(6) that serve as support during the injection. It also has second flaps
(7), más distantes de la boca (5) que las primeras solapas (6). Las segundas solapas (7) son utilizadas durante la aspiración y pueden ser más cortas que las primeras solapas (6). Generalmente las segundas solapas (7) son paralelas y en el mismo “plano” que las primeras solapas (6), como se ha representado. Sin embargo, también pueden tener otra orientación aunque es menos preferido. (7), more distant from the mouth (5) than the first flaps (6). The second flaps (7) are used during aspiration and can be shorter than the first flaps (6). Generally, the second flaps (7) are parallel and in the same "plane" as the first flaps (6), as shown. However, they can also have another orientation although it is less preferred.
Las solapas (6,7) pueden estar integradas en un mismo cuerpo (8) de forma que el ensamblado sea sencillo. El cuerpo (8) se fija a la carcasa (3) en una única operación, manteniendo la posición relativa de todos los elementos. The flaps (6,7) can be integrated into the same body (8) so that the assembly is simple. The body (8) is fixed to the casing (3) in a single operation, maintaining the relative position of all the elements.
Por su parte, el asa (2) del émbolo (1) posee alerones (9) que son de gran tamaño, similar a las primeras solapas (6) de la boca (5). Por ejemplo, los alerones (9) de una realización preferida tendrán una dimensión de 2 cm en cada dirección (4 cm total) y con forma arqueada o cóncava. Esta dimensión mayor asiste al movimiento retrógrado o de aspiración del émbolo (1), al favorecer el apoyo con la cara dorsal o ungueal del dedo pulgar. Los alerones (9) serán preferiblemente ergonómicos para incrementar la comodidad de uso, que influye en su fiabilidad. Igualmente tendrán una cara o las dos acolchadas, preferiblemente al menos la cara interior por donde se realiza el movimiento de aspiración. Igualmente las solapas (6,7) pueden acolcharse por sus lados enfrentados. For its part, the handle (2) of the plunger (1) has flaps (9) that are large, similar to the first flaps (6) of the mouth (5). For example, the ailerons (9) of a preferred embodiment will have a dimension of 2 cm in each direction (4 cm total) and have an arcuate or concave shape. This larger dimension assists in the retrograde or aspiration movement of the plunger (1), by favoring support with the dorsal or nail aspect of the thumb. The ailerons (9) will preferably be ergonomic to increase the comfort of use, which influences their reliability. They will also have one or both padded faces, preferably at least the inner face where the suction movement is carried out. Likewise, the flaps (6,7) can be padded on their opposite sides.
