Description

NUEVO ESPACIADOR-APLICADOR ADAPTABLE A PULVERIZADORES DE USO MEDICO O FARMACÉUTICO. NEW SPACER-APPLICATOR ADAPTABLE TO MEDICAL OR PHARMACEUTICAL SPRAYERS.

La presente invención se refiere a un nuevo espaciador-aplicador adaptable a pulverizadores de uso médico o farmacéutico, el cual presenta como principal característica, su reducido volumen, lo que le hace idóneo para ser portado por enfermos que tengan una dependencia permanente a este tipo de dispositivos, como es por ejemplo el caso de los enfermos asmáticos.The present invention relates to a new spacer-applicator adaptable to sprayers for medical or pharmaceutical use, which has as its main characteristic, its small volume, which makes it suitable for being carried by patients who have a permanent dependence on this type of devices, such as the case of asthmatic patients.

Son conocidos actualmente diversos tipos de aplicadores, los cuales preferentemente consisten en un tubo alargado que se conecta por uno de sus extremos al pulverizador, y que el otro se dirige a la cavidad bucal del paciente, o bien en mecanismos más complejos con los que el paciente tiene que soplar previamente, lo que determina que ese aire por él intro- ducido empuje a una válvula hacía el interior del mecanismo facilitando así la entrada de las partículas de la sustancia medicinal.Various types of applicators are currently known, which preferably consist of an elongated tube that connects at one end to the sprayer, and the other is directed to the patient's oral cavity, or in more complex mechanisms with which the The patient has to blow beforehand, which determines that the air introduced by him pushes a valve into the mechanism, thus facilitating the entry of the particles of the medicinal substance.

Ahora bien, el inconveniente de estos mecanismos radica en un elevado coste, en un tamaño que lo hace molesto para su transporte, y en la imposibilidad de ser utilizado en determina¬ dos pacientes, caso de los recien nacidos, al tener que soplar - previamente para hacer funcionar el aparato y posibilitar la entrada de la sustancia médica.However, the disadvantage of these mechanisms lies in a high cost, in a size that makes it annoying for transport, and in the impossibility of being used in certain patients, in the case of newborns, when having to blow - previously to operate the device and enable the entry of the medical substance.

La presente invención que mejora notablemente los modelos conocidos, consiste en un espaciador-aplicador apto para ser utilizado sobre los distintos tipos de pulverizadores de uso farmacéutico o médico existentes en el mercado, siendo de utilidad preferente en aquellos enfermos de vias respiratorias graves que necesiten una correcta exactitud en las dosis receta- das por el médico, en los asmáticos y en los recien nacidos,The present invention, which significantly improves the known models, consists of a spacer-applicator suitable for use on the different types of pharmaceutical or medical sprayers available on the market, being of preferential utility in those patients with severe respiratory tract who need a correct accuracy in the doses prescribed by the doctor, in asthmatics and in newborns,

Básicamente el espaciador-aplicador constituido en un material adecuado estará dotado de una serie de compartimentos suscepti¬ bles de ser inflados por el usuario o paciente, configurándose un cuerpo cónico en el que su extremo de mayor diámetro se adaptará a la zona buco-nasal del paciente, y el extremo de menor diámetro recibirá la aplicación del pulverizador corres¬ pondiente.Basically the spacer-applicator constituted in a suitable material will be provided with a series of compartments that can be inflated by the user or patient, configuring a conical body in which its larger diameter end will adapt to the buc-nasal area of the patient, and the smaller diameter end will receive the corresponding spray application.

Para la debida coπrarensión de este objeto, se adjunta a la presente memoria descriptiva una hoja de planos en la que a título de ejemplo queda representado:For the proper co-tension of this object, a sheet of drawings is attached to the present specification in which, by way of example, it is represented:

FIGURA PRIMERA.- Muestra una perspectiva del espaciador-aplicador hinchado.FIRST FIGURE.- Shows a perspective of the swollen spacer-applicator.

FIGURA SEGUNDA.- Es un detalle de utilización del espaciador- -aplicador y el pulverizador por parte del usuario.SECOND FIGURE.- It is a detail of the use of the spacer-applicator and the sprayer by the user.

En estas figuras aparecen referenciadas las siguientes partes princioales:The following main parts are referenced in these figures:

El espaciador-aplicador -1- estará constituido en -un material adecuado, que permita su plegado y su posterior inflado, Drefe- rentemente un material plástico, presentando forma anular cerrada de una sola pieza y con sus extremos abiertos. Toda su superficie o solo parte de la misma estará cubierta por una serie de compartimentos -2- susceptibles de ser hinchados a través de una válvula externa -3-. Mediante el insuflado de aire por el paciente a través de la válvula -3-, se consigue el inflamado y armado del espaciador- -aplicador, constituyéndose un cuerpo tronco-cónico en el que su extremo de mayor diámetro -4- estará conformado de manera que se adaote anatómicamente a la zona buco-nasal del paciente, mientras que su extremo menor -5- será el encargadoThe spacer-applicator -1- will be constituted in -a suitable material, which allows its folding and subsequent inflation, mainly a plastic material, presenting a closed annular shape in one piece and with its open ends. All its surface or only part of it will be covered by a series of compartments -2- capable of being swollen through an external valve -3-. Through the insufflation of air by the patient through the valve -3-, the inflamed and armed spacer- -applicator is achieved, constituting a trunk-conical body in which its end of greater diameter -4- will be shaped so that is anatomically adapted to the patient's buco-nasal area, while its lower end -5- will be in charge

1 HOJA SUSTITU I DA de recibir en forma de encaje al correspondiente pulverizador -6-.1 SUBSTITUTE SHEET I DA to receive the corresponding sprayer -6- in the form of a socket.

Operativamente, el espaciador-aplicador una vez hinchado a través de la válvula -3- y adaptado oor su extremo -4- en la cara del paciente y una vez que se encuentre montado el pulverizador -6-, no habrá más que actuar sobre este último para que las partículas medicinales -7- canalizads en el cono -1- se dirijan hacia la boca y nariz del paciente que así podrá aspirarlas en cantidad suficiente.Operationally, the spacer-applicator once swollen through the valve -3- and adapted by its end -4- on the patient's face and once the sprayer -6- is mounted, there will be nothing more to act on this last so that the medicinal particles -7- canalizads in the cone -1- are directed towards the mouth and nose of the patient so that they can aspirate them in sufficient quantity.

Las ventajas de este nuevo espaciador-aplicador radican en que deshinchado, el cuerpo físico que ocupa es mínimo con lo cual es apto para ser transportado y utilizado en cualquier lugar y momento, mejorándose además la cantidad de partículas de sustancia medicinal que penetran en el enfermo consiguiéndose en cada pulverización una correcta toma de las dosis recetadas por el médico.The advantages of this new spacer-applicator lie in that deflated, the physical body it occupies is minimal with which it is suitable to be transported and used at any place and time, also improving the amount of particles of medicinal substance that penetrate the patient getting in each spray a correct take of the doses prescribed by the doctor.

Descrita suficientemente la naturaleza de la invención, se hace constar expresamente que cualquier modificación de detalle que se introduzca en la misma se consideraran incluidas dentro de esta protección, en tanto que no altere o modifique esencial- mente su finalidad característica.Describing sufficiently the nature of the invention, it is expressly stated that any modification of detail that is introduced therein will be considered included in this protection, as long as it does not alter or essentially modify its characteristic purpose.
