Description
Casco per ventilazione non invasiva Helmet for non-invasive ventilation
La presente invenzione riguarda un casco per ventilazione non invasiva, ed in particolare un casco provvisto di mezzi per migliorare la tenuta del casco nella sua parte di contatto con il collo dell'utente. The present invention relates to a helmet for non-invasive ventilation, and in particular to a helmet provided with means for improving the seal of the helmet in its part in contact with the user's neck.
Un casco noto comprende un involucro gonfiabile provvisto di una parete flessibile atta ad essere disposta intorno al collo dell'utente. La parete flessibile è provvista di un'apertura per il collo e può essere provvista di una cuffia gonfiabile con un diametro molto maggiore di 5 cm, allo scopo di ridurre il volume interno dell'involucro gonfiabile per migliorare la precisione di misura della respirazione dell'utente. Tale cuffia gonfiabile non impedisce tuttavia perdite d'aria tra il collo dell'utente e la parete flessibile, con conseguenti problemi di efficacia e d'uso del casco. A known helmet comprises an inflatable casing provided with a flexible wall adapted to be arranged around the user's neck. The flexible wall is provided with an opening for the neck and can be provided with an inflatable cuff with a diameter much greater than 5 cm, in order to reduce the internal volume of the inflatable envelope to improve the measurement accuracy of the breathing of the user. However, this inflatable cap does not prevent air leaks between the user's neck and the flexible wall, with consequent problems in the effectiveness and use of the helmet.
Scopo della presente invenzione è pertanto quello di fornire un casco esente da tali inconvenienti. Detto scopo viene conseguito con un casco le cui caratteristiche principali sono specificate nella prima rivendicazione, mentre altre caratteristiche sono specificate nelle restanti rivendicazioni. The object of the present invention is therefore to provide a helmet free from such drawbacks. Said object is achieved with a helmet whose main characteristics are specified in the first claim, while other characteristics are specified in the remaining claims.
Grazie al particolare collare gonfiabile, la parete flessibile viene stretta intorno al collo in maniera ottimale e facilmente regolabile attraverso regolazioni della pressione di gas nel collare gonfiabile, così da impedire perdite d'aria senza tuttavia causare fastidio all'utente od altri problemi nell'uso del casco. Thanks to the particular inflatable collar, the flexible wall is tightened around the neck in an optimal and easily adjustable way through gas pressure adjustments in the inflatable collar, so as to prevent air leaks without however causing discomfort to the user or other problems in use. of the helmet.
Inoltre, essendo molto più piccolo della suddetta cuffia gonfiabile del casco noto, il collare gonfiabile del casco secondo la presente invenzione consente di disporre vicino al collo dell'utente dispositivi medico-chirugici, ad esempio cateteri venosi, anche relativamente ingombranti, senza particolari problemi di interferenza, quali lesioni da decubito, occlusione delle infusioni o rottura della stessa cuffia gonfiabile. Moreover, being much smaller than the aforementioned inflatable cuff of the known helmet, the inflatable collar of the helmet according to the present invention allows medical-surgical devices, for example venous catheters, even relatively bulky, to be arranged near the user's neck, even if relatively bulky, without particular problems of interference, such as pressure sores, occlusion of infusions or rupture of the inflatable cuff itself.
Ulteriori vantaggi e caratteristiche del casco secondo la presente invenzione risulteranno evidenti agli esperti del ramo dalla seguente descrizione dettagliata e non limitativa di una sua forma realizzativa con riferimento agli annessi disegni in cui: Further advantages and characteristics of the helmet according to the present invention will become evident to those skilled in the art from the following detailed and non-limiting description of an embodiment thereof with reference to the attached drawings in which:
la figura 1 mostra una vista frontale del casco; e Figure 1 shows a front view of the helmet; And
- la figura 2 mostra una vista parziale in sezione del casco di figura 1. - figure 2 shows a partial sectional view of the helmet of figure 1.
Facendo riferimento alle figure 1 e 2, si vede che il casco secondo la presente invenzione comprende in modo noto un involucro gonfiabile 1, di forma sostanzialmente cilindrica ed almeno parzialmente trasparente, atto ad essere disposto sulla testa 2 di un utente attraverso un'apertura ricavata in una parete flessibile 3 atta ad essere disposta intorno al collo 4 dell'utente. L'involucro gonfiabile 1 è provvisto di almeno un condotto d'ingresso 5 ed almeno un condotto d'uscita 6 per l'aria nell'involucro gonfiabile 1, in modo che la pressione positiva PI dell'aria nell'involucro gonfiabile 1 può essere mantenuto maggiore della pressione esterna, in particolare con una pressione positiva PI compresa tra 4 e 24 cm/H20, ovvero tra circa 400 e 2400 Pa. With reference to Figures 1 and 2, it can be seen that the helmet according to the present invention comprises, in a known way, an inflatable casing 1, substantially cylindrical in shape and at least partially transparent, able to be arranged on the head 2 of a user through an opening obtained in a flexible wall 3 adapted to be arranged around the user's neck 4. The inflatable envelope 1 is provided with at least one inlet duct 5 and at least one outlet duct 6 for the air in the inflatable envelope 1, so that the positive pressure P1 of the air in the inflatable envelope 1 can be maintained greater than the external pressure, in particular with a positive pressure PI between 4 and 24 cm / H20, or between about 400 and 2400 Pa.
La parete flessibile 3 è provvista di almeno un collare gonfiabile 7 che circonda l'apertura per la testa 2 e che presenta un diametro medio D minore di 3 cm, in particolare compreso tra 1,5 e 2,5 cm. Il collare gonfiabile 7 è collegato ad un condotto ausiliario 8 che attraversa la parete flessibile 3 e/o l'involucro gonfiabile 1, in modo da gonfiare nell'uso il collare gonfiabile 7 con un gas pompato da un dispositivo esterno (non mostrato nelle figure) attraverso il condotto ausiliario 8 ad una pressione P2 maggiore della pressione PI nell'involucro gonfiabile 1, in particolare una pressione positiva P2 compresa tra 15 e 28 cm/H20, ovvero tra circa 1500 e 2800 Pa, rispetto alla pressione all'esterno dell'involucro gonfiabile 1. Il collare gonfiabile 7 è preferibilmente fissato alla parete flessibile 3, in particolare realizzato in un solo pezzo con quest'ultima, in modo da migliorare l'uso e l'affidabilità del casco. The flexible wall 3 is provided with at least one inflatable collar 7 which surrounds the opening for the head 2 and which has an average diameter D less than 3 cm, in particular between 1.5 and 2.5 cm. The inflatable collar 7 is connected to an auxiliary duct 8 which crosses the flexible wall 3 and / or the inflatable envelope 1, so as to inflate the inflatable collar 7 in use with a gas pumped by an external device (not shown in the figures ) through the auxiliary duct 8 at a pressure P2 higher than the pressure PI in the inflatable envelope 1, in particular a positive pressure P2 between 15 and 28 cm / H20, i.e. between about 1500 and 2800 Pa, with respect to the pressure outside the inflatable casing 1. The inflatable collar 7 is preferably fixed to the flexible wall 3, in particular made in one piece with the latter, so as to improve the use and reliability of the helmet.
Eventuali varianti e/o aggiunte possono essere apportate dagli esperti del ramo alla forma realizzativa dell'invenzione qui descritta ed illustrata restando nell’ambito delle seguenti rivendicazioni. Any variations and / or additions can be made by those skilled in the art to the embodiment of the invention described and illustrated herein, remaining within the scope of the following claims.
