DESCRIZIONE DESCRIPTION
Campo di applicazione Field of application
La presente invenzione si riferisce al campo tecnico degli apparati medicali, e riguarda in particolare un metodo per la realizzazione di una interfaccia per la ventilazione meccanica a partire da una maschera per sport acquatici o da lavoro, nonch? una interfaccia cos? realizzata e un apparato di ventilazione meccanica che comprende tale maschera o casco respiratore. The present invention relates to the technical field of medical devices, and in particular relates to a method for making an interface for mechanical ventilation starting from a water sports or work mask, as well as a method for making an interface for mechanical ventilation. an interface cos? realized and a mechanical ventilation apparatus which includes such mask or respirator helmet.
Stato della Tecnica State of the art
E? noto che per sottoporre un paziente a ventilazione meccanica occorre un apparato che include un compressione atto ad erogare aria e/o ossigeno in pressione, un tubo per il trasporto di quest?ultimo ed un?interfaccia da porre sul viso del paziente, generalmente una maschera o un casco. AND? It is known that to subject a patient to mechanical ventilation, an apparatus is required that includes a compression capable of delivering pressurized air and / or oxygen, a tube for transporting the latter and an interface to be placed on the patient's face, generally a mask or a helmet.
La ventilazione meccanica a pressione positiva continua (C-PAP), impiegata ad esempio per curare forti polmoniti, prevede un?interfaccia avente un ingresso collegabile al tubo di cui sopra ed un?uscita fluidicamente collegata con una valvola atta a creare perdite di carico lungo la linea. In tal modo, la pressione nella camera di lavoro che si crea fra interfaccia e utente ? sempre positiva, il che consente agli alveoli polmonari di non svuotarsi mai completamente. Continuous positive pressure mechanical ventilation (C-PAP), used for example to treat severe pneumonia, provides an interface having an inlet that can be connected to the aforementioned tube and an outlet that is fluidically connected to a valve capable of creating long pressure drops. the line. In this way, the pressure in the working chamber that is created between the interface and the user? always positive, which allows the pulmonary alveoli to never empty completely.
Generalmente, l?interfaccia ? costituita da maschere o caschi respiratori. Generally, the interface? consisting of breathing masks or helmets.
La maschera non risulta particolarmente confortevole per il paziente, sia in fase di posizionamento sul viso che durante la ventilazione meccanica vera e propria. Per questo motivo, si preferisce usare il casco respiratore, che tuttavia presenta degli ingombri maggiori. The mask is not particularly comfortable for the patient, both in the positioning phase on the face and during the actual mechanical ventilation. For this reason, it is preferred to use the respirator helmet, which however has larger dimensions.
In situazione di emergenza, come ad esempio quella che si sta vivendo oggi in Italia, le interfacce spesso mancano. La cosa, nei casi estremi, pu? portare a gravi danni per il paziente, o addirittura alla sua morte. In an emergency situation, such as the one we are experiencing today in Italy, interfaces are often missing. The thing, in extreme cases, can? lead to serious harm to the patient, or even to his death.
Presentazione dell?invenzione Presentation of the invention
Scopo della presente invenzione ? quello di ovviare agli inconvenienti sopra illustrati, mettendo a disposizione un metodo per la realizzazione di un?interfaccia per la ventilazione meccanica a partire da una maschera per sport acquatici, ad esempio pesca subacquea o snorkeling, o da lavoro, ad esempio per lavori in ambito agricolo. Purpose of the present invention? that of obviating the drawbacks illustrated above, by providing a method for creating an interface for mechanical ventilation starting from a mask for water sports, for example underwater fishing or snorkeling, or for work, for example for work in the field agricultural.
Tale scopo, nonch? altri che saranno pi? chiari in seguito, ? raggiunto dal metodo, dall?interfaccia e dall?apparato in accordo con quanto qui descritto, illustrato e/o rivendicato. This purpose, as well as? others who will be more? clear later,? achieved by the method, by the interface and by the apparatus in accordance with what is described, illustrated and / or claimed herein.

Descrizione dettagliata di alcuni esempi di realizzazione preferiti Detailed description of some preferred embodiments
Facendo riferimento alle figure citate, si descrive un metodo per la realizzazione di un?interfaccia 1 per la ventilazione meccanica di un paziente. With reference to the cited figures, a method is described for the realization of an interface 1 for the mechanical ventilation of a patient.
Si potr? predisporre una maschera facciale 10, preferibilmente anche se non esclusivamente per sport acquatici, come illustrato in FIG.1. Will it be possible? prepare a face mask 10, preferably although not exclusively for water sports, as illustrated in FIG. 1.
In particolare, tale maschera 10 per sport acquatici potr? essere realizzata secondo gli insegnamenti della domanda di brevetto europeo EP3140186 oppure della domanda francese FR2720050. In particular, such a mask 10 for water sports will be able to? be made according to the teachings of the European patent application EP3140186 or of the French application FR2720050.
Anche se nel prosieguo ci si riferir? ad una maschera per sport acquatici, si comprende che potr? essere impiegata una maschera facciale da lavoro, ad esempio per lavori in ambito agricolo. Even if in the following we will refer? to a mask for water sports, it is understood that it can? a work face mask be used, for example for agricultural work.
La maschera 10 includer? un visore 15? otticamente trasparente, ad esempio uno schermo in materiale polimerico o vetro e una guarnizione 16 sostanzialmente anulare accoppiata lo stesso visore 15?. Mask 10 will include? a viewer 15? optically transparent, for example a screen made of polymeric material or glass and a substantially annular gasket 16 coupled to the same visor 15 ?.
Opportunamente, visore 15? e guarnizione 16 coopereranno reciprocamente in modo che una volta che la guarnizione 16 viene posta sul viso del paziente definisca con lo stesso una camera di lavoro 17 sostanzialmente a tenuta che copre occhi, naso e bocca del paziente, come ad esempio illustrato in FIG.6. Appropriately, viewer 15? and seal 16 will mutually cooperate so that once the seal 16 is placed on the patient's face it defines with it a substantially sealed working chamber 17 which covers the patient's eyes, nose and mouth, as illustrated for example in FIG. .
La maschera 10 potr? inoltre comprendere una apertura 11 e aperture 12, 12? per collegare reciprocamente la camera di lavoro 17 e l?ambiente esterno. The mask 10 will be able to? further comprise an opening 11 and openings 12, 12? to reciprocally connect the work chamber 17 and the external environment.
L?apertura 11 potr? essere collegata con il tubo P1, di tipo in s? noto, il quale a sua volta potr? essere collegato in modo in s? noto con mezzi di adduzione di un fluido di lavoro, ad esempio una macchina che eroga ossigeno e aria in pressione. The opening 11 will be able to? be connected with the tube P1, type in s? known, which in turn can? be connected so in s? known with means for supplying a working fluid, for example a machine that delivers oxygen and air under pressure.
Le aperture 12, 12? potranno essere collegate con mezzi per la creazione di perdite di carico, ad esempio una valvola 25 di tipo in s? noto. Tale collegamento potr? essere diretto come illustrato nelle FIGG. 16 e 17, oppure previo inserimento di un tubo P2, in s? noto, come illustrato nelle FIGG.14 e 15. The openings 12, 12? can they be connected with means for the creation of pressure drops, for example a valve 25 of the type in s? known. This link will be able? be directed as illustrated in FIGS. 16 and 17, or after inserting a pipe P2, in s? known, as illustrated in FIGS. 14 and 15.
Nell?esempio di realizzazione non esclusivo qui illustrato, il collegamento di cui sopra avverr? previa rimozione dalla maschera 10 del boccaglio B, come illustrato nelle FIGG.1 e 2. Tale operazione scoprir? il collettore 18, il quale comprende le aperture 11, 12, 12?. In the non-exclusive implementation example illustrated here, the above connection will occur. after removing the mouthpiece B from the mask 10, as illustrated in FIGS. 1 and 2. This operation will reveal? the manifold 18, which includes the openings 11, 12, 12 ?.
A tale collettore 18 potr? essere accoppiato un raccordo 20 avente una prima linea di collegamento fluidico 21? con una porta 21 a cui viene collegato il tubo P1 e una seconda linea di collegamento fluidico 22? con una porta 22 a cui vengono collegati i mezzi di creazione delle perdite di carico 25 ed eventualmente il tubo P2. To such collector 18 will be able? be coupled to a fitting 20 having a first fluidic connection line 21? with a port 21 to which the tube P1 is connected and a second fluidic connection line 22? with a door 22 to which the means for creating the pressure drops 25 and possibly the pipe P2 are connected.
Opportunamente, il raccordo 20 e il collettore 18 potranno comprendere mezzi di accoppiamento reciproco del tipo a maschio e femmina, ad esempio un accoppiamento di forma come illustrato in FIG.4. Conveniently, the fitting 20 and the manifold 18 may comprise mutual coupling means of the male and female type, for example a shape coupling as illustrated in FIG.4.
Vantaggiosamente, la maschera 10 potr? comprendere una valvola a membrana antisoffocamento 15, la quale potr? comprendere la membrana 15?? e la sezione di passaggio 15?. Advantageously, the mask 10 will be able to comprise an anti-suffocation diaphragm valve 15, which can? understand the membrane 15 ?? and the passage section 15 ?.
Nell?esempio di cui sopra, tale valvola potr? essere ottenuta capovolgendo la valvola esistente, atta ad espellere l?aria e/o l?acqua una volta sott?acqua senza che l?acqua entri nella maschera. In the above example, this valve will be able to be obtained by overturning the existing valve, designed to expel the air and / or water once underwater without the water entering the mask.
Grazie a quanto sopra, ? possibile realizzare un apparato per la ventilazione meccanica di un paziente anche in assenza di caschi o maschere respiratori dello stato della tecnica. Thanks to the above,? It is possible to realize an apparatus for the mechanical ventilation of a patient even in the absence of helmets or respiratory masks of the state of the art.
La maschera 10, infatti, potr? essere collegata ai mezzi di adduzione di un fluido di lavoro mediante il tubo P1 e ai mezzi per la creazione di perdite di carico 25 direttamente o mediante il tubo P2. In uso, sar? sufficiente porre sul viso del paziente la maschera 10, fare i collegamenti di cui sopra e poi accendere i mezzi di adduzione del fluido di lavoro. The mask 10, in fact, can? be connected to the means for supplying a working fluid by means of the pipe P1 and to the means for creating pressure drops 25 directly or by means of the pipe P2. In use, sar? it is sufficient to place the mask 10 on the patient's face, make the above connections and then switch on the means for supplying the working fluid.
Si comprende che i mezzi di adduzione del fluido di lavoro, il tubo P1, i mezzi per la creazione di perdite di carico 25 e qualora presente il tubo P2 potranno essere di tipo in s? noto, in modo da definire ad esempio con la maschera 10 un apparato per la ventilazione meccanica a pressione positiva continua (C-PAP). It is understood that the means for supplying the working fluid, the pipe P1, the means for creating pressure drops 25 and, if present, the pipe P2 may be of the type in s? known, so as to define for example with the mask 10 an apparatus for continuous positive pressure mechanical ventilation (C-PAP).
Da quanto sopra descritto si comprende che l?invenzione raggiunge gli scopi prefissatisi. From what has been described above it can be understood that the invention achieves the intended aims.
L?invenzione ? suscettibile di numerose modifiche e varianti, tutte rientranti nelle rivendicazioni allegate.
