DESCRIZIONE DEL MODELLO DI UTILITA’ dal titolo “Catetere per la somministrazionediunsurfattantepolmonare” DESCRIPTION OF THE UTILITY MODEL entitled "Catheter for the administration of a pulmonary surfactant"
Il presente trovato riguarda un catetere per la somministrazione di un surfattantepolmonare inneonatipreterminesofferentie/oa rischiodisindrome dadistress respiratorio. The present invention relates to a catheter for administering a pulmonary surfactant in preterms suffering and / or at risk of respiratory distress syndrome.
Piùspecificamente,ilpresentetrovatoriguardauncatetereperl’instillazionedi unsurfattantepolmonareinneonaticherespirinospontaneamenteemantenutiin pressione respiratoria positiva continua nasale (CPAP – continuous positive airwayspressure). More specifically, the present retrovator concerns a catheter for the instillation of a pulmonary surfactant in neonates with spontaneous breaths and maintained in continuous positive airways pressure (CPAP).
Neiduedecenni scorsi la terapiadi somministrazionedi surfattantipolmonari esogenièstatafondamentaleneltrattamentodineonatipretermine ocometerapia disoccorsoinneonatiaffettidadisturbidellamembranaialina,comeperesempio la sindromeda distress respiratorio. Con l’evoluzionee ilmiglioramentodimolti altriaspettidicuradeineonatipretermineècambiatoanchel’utilizzodellaterapia deisurfattantipolmonari. Over the past two decades, the administration of exogenous pulmonary surfactants has been fundamental in the treatment of newborn preterm or rescue comotherapy in infants affected by membrane disturbances, such as respiratory distress syndrome. With the evolution and improvement of many other safety aspects of these new terms, the use of lung surfactant therapy has also changed.
In particolare, nell’ultimo decennio si è verificato un significativo aumento dell’impiego dellapressionerespiratoriapositivacontinuanasalecomestrumento principale di supporto respiratorio, così da evitare in molti casi l’intubazione endotracheale. In particular, in the last decade there has been a significant increase in the use of continuous positive respiratory pressure in the body as the main respiratory support tool, so as to avoid endotracheal intubation in many cases.
Tuttavia, riconoscendo i meriti dei surfattanti polmonari, in particolarequando somministratiprecocemente,inalcunicasisipuòdeciderediintubareineonatiper consentire la somministrazione di surfattanti polmonari e successivamente immediatamente estubarli al fine di procedere con l’applicazione della pressione respiratoria positiva continua nasale. Questo approccio riduce il rischio di una successivaventilazionemeccanicae ilrischioassociatodipneumotorace. However, recognizing the merits of pulmonary surfactants, particularly when administered early, in some cases it can be decided to intubate infants to allow the administration of pulmonary surfactants and subsequently immediately extubate them in order to proceed with the application of continuous nasal positive respiratory pressure. This approach reduces the risk of subsequent mechanical ventilation and the associated risk of pneumothorax.
L’intubazione della trachea per il solo scopo della somministrazione di surfattanti polmonari nonè tuttaviaprivadi pericoliperchépuòesserecomplicata da numerosi tentativi richiesti e da un rischio di ipossia durante la procedura. Inoltre, l’intubazione viene quasi sempre eseguita con una pre-medicazione con narcoticie rilassanti deimuscoli,equestoporta a unritardo nell’estubazione dopo cheilsurfattantepolmonare èstatosomministrato. However, intubation of the trachea for the sole purpose of administering pulmonary surfactants is not without danger because it can be complicated by numerous attempts required and by a risk of hypoxia during the procedure. In addition, intubation is almost always performed with a pre-medication with narcotic and relaxing muscles, leading to a delay in extubation after the pulmonary surfactant has been administered.
Alla luce delle difficoltà associate con l’intubazione legata unicamente alla somministrazione di surfattanti polmonari, sonostati ideati metodi alternativi per lalorosomministrazione notiinletteraturecometerapiasurfattante minimamente invasiva (MIST – minimally invasive surfactant therapy) o eliminazione della ventilazionemeccanica(AMV– avoidmechanicalventilation). In light of the difficulties associated with intubation linked solely to the administration of pulmonary surfactants, alternative methods have been devised for their administration of well-known literature therapy and minimally invasive surfactant therapy (MIST - minimally invasive surfactant therapy) or elimination of mechanical ventilation (AMV - avoid mechanical ventilation).
Tali metodi prevedono una tecnica di intubazione tracheale meno invasiva utilizzando cateteri più piccoli oppure tubi (naso)-gastrici. L’uso del tubo di alimentazione altamente flessibile che deve però essere spinto nella trachea tramitelapinzadiMagillnonèconsigliabile perun’applicazionesulargascala. Scopodelpresentetrovato èdunquequellodiproporreunnuovocatetereperla somministrazione di un surfattante polmonare che possa essere facilmente utilizzatosulargascalaechesiamigliorativoperlacompliance dei neonati. These methods involve a less invasive tracheal intubation technique using smaller catheters or (nose) -gastric tubes. The use of the highly flexible feeding tube, which must however be pushed into the trachea by the Magill forceps, is not recommended for an application on a scale. The aim of the present finding is therefore to propose a new catheter for the administration of a pulmonary surfactant that can be easily used in the lungs and is better for compliance with infants.

Modi particolari di realizzazione formano oggetto delle rivendicazioni dipendenti, il cui contenuto è da intendersi come parte integrante della presente descrizione. Particular embodiments form the subject of the dependent claims, the content of which is to be understood as an integral part of the present description.
Ulteriori caratteristiche e vantaggi del trovato appariranno dalla descrizione dettagliata che segue, effettuata a puro titolo di esempio non limitativo, con riferimentoaidisegniallegati,neiquali: Further characteristics and advantages of the invention will appear from the following detailed description, carried out purely by way of non-limiting example, with reference to the accompanying drawings, in which:

In figura 1 è illustrato un catetere 1 secondo il presente trovato. Il catetere 1 comprende un tubo 2 di materiale flessibile, preferibimente un polimero di propileneetilenefluorinato,aventesiaunarigidezzasufficienteperpermetternela guidaversoe oltre lecordevocali siaunaelasticitàeunamorbidezzasufficientida evitaredanniallecordevocalioaltrestrutturevitalidurantel’intubazione. Figure 1 illustrates a catheter 1 according to the present invention. The catheter 1 comprises a tube 2 of flexible material, preferably a propylene-ethylene-fluorinated polymer, having sufficient stiffness to allow it to be guided through and beyond the evocative cords, both an elasticity and a softness sufficient to avoid damage to the cords and other vital structures during intubation.
Il tubo 2 può essere spinto sotto diretto controllo visivo utilizzando un laringoscopio e il surfattante polmonare viene somministrato preferibilmente in unoodueboli. The tube 2 can be pushed under direct visual control using a laryngoscope and the pulmonary surfactant is preferably administered in an oooduebole.
Il tubo è preferibilmente di colore blu. Può avere una lunghezza compresa tra 100 e 300 mm, preferibilmente 300 mm oppure 135 mm o ancora più preferibilmente 130 mm, e ha un diametro esterno compreso tra 5 French (1,65 mm)e3,5French (1,155mm),preferibilmenteparia 5French. The tube is preferably blue in color. It can have a length comprised between 100 and 300 mm, preferably 300 mm or 135 mm or even more preferably 130 mm, and has an external diameter comprised between 5 French (1.65 mm) and 3.5French (1.155mm), preferably several 5French.
Il catetere 1 comprende inoltre un corpo di supporto 4 fissato a un’estremità prossimale 2a al tubo 2 e predisposto per essere accoppiato, a un’altra sua estremità 6, a una siringa non mostrata in figura e contenente il surfattante polmonare dasomministrare. The catheter 1 also comprises a support body 4 fixed at a proximal end 2a to the tube 2 and designed to be coupled, at its other end 6, to a syringe not shown in the figure and containing the pulmonary surfactant to be administered.
Il tubo2èprovvistodiunapluralitàdi tacche8,prefebilmentebianche,attea segnalareuna lunghezzaprogressivadel tubo2 rispetto aun’estremitàdistale2b deltubo2. L’estremitàdistale2brappresentalapuntadelcatetereed èarrotondata eliscia. Pipe2 is provided with a plurality of notches8, preferably white, to indicate a progressive length of pipe2 with respect to a distal end2b of pipe2. The distal end 2 is at the tip of the catheter and is rounded and smooth.

La peculiarità dei numeri romani uno, due e tre è che corrispondono rispettivamenteaunataccalinearesingola(ilnumerounocheinnumeriromaniè scritto“I”),aunataccalinearedoppia(ilnumeroduecheinnumeriromanièscritto “II”)eaunataccalinearetripla(ilnumerotrecheinnumeriromanièscritto“III”). In una forma di realizzazione più generale, la prima, seconda e terza tacca, non devono necessariamente rappresentare numeri romani, ma possono semplicementeincludereunasingola,doppiaotriplataccalineare:soloperfareun esempio, il sistema di tacche progressive può essere realizzato mediante linee continuechiusea formareanelli intornoal tubo.Talecaratteristica fondamentale del presente modello di utilità offre il vantaggio di essere immediatamente e facilmente“leggibile”ancheincondizioniavversedivisibilità,comeperesempiole condizionioperative descritte sopra. L’utente (peresempiounMedico)nondeve necessariamente “leggere” il numero,mapuò ricevereunapercezione immediata dalla taccasingola,doppiaotripla.E’unapercezioneintuitivadelsistemaditacche progressivechepuòaiutarequandosioperainsituazioniambientalidifficili. In a particular form of realization, a first notch 8a is represented by the Roman number one, i.e. I, a second notch 8b is represented by the Roman number two, i.e. II, a third notch8c is represented by the Roman number three, i.e. III. The peculiarity of the Roman numerals one, two and three is that they correspond respectively to a single block (the number one, which number of Romans is written "I"), to a double line (the number of two numbers in the Romans is written "II") and to a triple line (the number three in number of Romans is written "III"). In a more general embodiment, the first, second, and third notches do not necessarily have to represent Roman numerals, but can simply include a single, double or triple linear line: for example only, the system of progressive notches can be made by continuous lines which can form rings around the tube. this utility model offers the advantage of being immediately and easily "readable" even in conditions of adverse visibility, as for example the operating conditions described above. The user (for example a doctor) does not necessarily have to "read" the number, but can receive an immediate perception from the single, double or triple notebook.
Ogni tacca è posta a una distanza predeterminata D, preferibilmente 1cm, da quellaprecedente. Each notch is placed at a predetermined distance D, preferably 1cm, from the previous one.

Le prime tre tacche 8a, 8b e 8c non hanno i numeri arabi perché essi non sarebbero facilmente visibili durante le fase iniziali dell’intubazione, a causa della posizionedellaboccadelneonato. There are then 2 other notches 8e on the tube, each placed at the distance D with respect to the previous notch and being represented by a line section accompanied by progressive numbers, preferably six (6) anove (9). In a preferred form of embodiment, Roman numerals are present on two opposite sides of the tube 2 (front and back), at a distance of 180 °, in order to allow easy reading in any position within the tube 2 with respect to the operator. The first three notches 8a, 8b and 8c do not have Arabic numbers because they would not be easily visible during the initial phase of intubation, due to the position of the baby's mouth.
In figura 2 è mostrato frontalmente il catetere di figura 1 in modo da poter vedereinmanierapiùchiaraletaccheprogressive8. Figure 2 shows the catheter of figure 1 from the front so as to be able to see more clearly of the progressive patches8.
