Description

Descrizione dell' invenzione industriale dal titolo: "Nebulizzatore, duplice di anestetici locali e/o farmaci per indurre e mantenere l' anestesia, topica laringo-tracheale in corso di intubazione endotracheale, che termina con un duplice manicotto cribrato: uno prima della cuffia del tubo e l' altro immediatamente dopo di essa; che consente così di indurre e mantenere l' anestesia topica laringo- tracheale nel corso di intubazioni endotracheali" Description of the industrial invention entitled: "Nebulizer, dual of local anesthetics and / or drugs to induce and maintain anesthesia, topical laryngeal-tracheal during endotracheal intubation, which ends with a double crystallized sleeve: one before the cuff of the tube and the other one immediately after it; thus allowing the induction and maintenance of topical laryngotracheal anesthesia during endotracheal intubations "

RIASSUNTO SUMMARY

La presente invenzione industriale riguarda un dispositivo costituito da un tubo endotracheale modificato per poter consentire oltre ad una normale intubazione endotracheale una contemporanea nebulizzazione periodica e ripetibile, o continua di farmaci sulla laringe e sulla trachea nel corso di ventilazione artificiale per anestesie generali o per trattamenti intensivo-rianimatori . The present industrial invention relates to a device consisting of an endotracheal tube modified to allow, in addition to normal endotracheal intubation, a simultaneous periodic and repeatable or continuous nebulization of drugs on the larynx and trachea during artificial ventilation for general anesthesia or for intensive treatments. - resuscitators.

E' caratteristico del ritrovato un duplice dispositivo per la irrigazione di farmaci, anestetici locali ed altri, inserito in un normale tubo endotracheale, che termina, per la sua parte superiore, immediatamente prima dell’ inizio della cuffia con.una porzione distale a manicotto, indovata sempre nello spessore della parete del tubo e cribrata all’ esterno che consente una diffusione omogenea deifarmaci; La sua parte inferiore indipendente dalla prima, termina anch' essa con un manicotto distale cribrato situato oltre la cuffia endotracheale, alloggiato anch' esso nello spessore della parete del tubo. A double device for the irrigation of drugs, local anesthetics and others is characteristic of the invention, inserted in a normal endotracheal tube, which ends, for its upper part, immediately before the start of the cuff with a distal sleeve portion, always found in the thickness of the wall of the tube and crusted on the outside which allows a homogeneous diffusion of the drugs; Its lower part, independent from the first, also ends with a distal crystallized sleeve located beyond the endotracheal cuff, also housed in the thickness of the tube wall.

Somministrando un anestetico locale tr amite il dispositivo si determina una pronta anestesia topica laringo tracheale. Detta anestesia topica è riproducibile nelle sue stesse modalità al venir meno dell' effetto farmacologico indotto dalla precedente somministrazione con una dose suppletiva di farmaco. Altr imenti l’ anestesia topica laringo-tracheale può essere mantenuta in modo inalterato e continuo con la perfusione di una soluzione anestetica mediante una pompa-siringa programmata. By administering a local anesthetic through the device, a prompt topical laryngeal tracheal anesthesia is determined. Said topical anesthesia is reproducible in its own modalities in the absence of the pharmacological effect induced by the previous administration with a supplementary dose of the drug. Otherwise, topical laryngotracheal anesthesia can be maintained unaltered and continuously with the perfusion of an anesthetic solution using a programmed syringe pump.

E' quindi un ritrovato di comoda applicazione e facilità d’impiego che consente di raggiungere con un’ unica manovra il duplice effetto dell' intubazione e dell' anestesia topica laringo tracheale. It is therefore an invention of convenient application and ease of use that allows you to achieve the dual effect of intubation and topical laryngeal tracheal anesthesia with a single maneuver.

Permette di mantenere queste due coesistenti condizioni somministrando la quantità necessaria di farmaco tramite l' apposito raccordo mediante una somministrazione periodica di anestetico locale con una normale siringa o tramite una perfusione continua del dispositivo con una pompa siringa. It allows to maintain these two coexisting conditions by administering the necessary quantity of drug through the special fitting by means of a periodic administration of local anesthetic with a normal syringe or through a continuous perfusion of the device with a syringe pump.

Questo duplice apparato inoltre per le sue modalità costruttive, non interferisce minimamente con la necessaria distensione della cuffia del tubo endotracheale. Moreover, this double apparatus, due to its construction methods, does not interfere in the least with the necessary distension of the cuff of the endotracheal tube.

E quindi un dispositivo che consente l' uso di metodiche di facile esecuzione, ripetibili e non invasive per il paziente. It is therefore a device that allows the use of methods that are easy to perform, repeatable and non-invasive for the patient.

è rappresentata l' invenzione industriale nella sua prospettiva laterale; sonoinoltreraffiguratetre sezioni trasverse di esse. the industrial invention is represented in its lateral perspective; three transverse sections of them are also depicted.

L' invenzione industriale,è costituita da un duplice tubicino (12),analogo a quello (5) utilizzato per il riempimento con aria della cuffia (8) del tubo endotracheale (1). Il duplice tubicino converge nella sua estremità prossimale in un unico raccordo (17) a dispositivo valvolare, per una normale stringa o per una pompa siringa, attraverso le quali si iniettano i farmaci. Il suo primo duplice tratto (12) è esterno al tubo endotracheaie e non adeso ad esso. Nel suo secondo tratto il duplice dispositivo (13, 18) decorre nello spessore delle pareti superiore ed inferiore del tubo endotracheale e termina: quello The industrial invention consists of a double tube (12), similar to that (5) used for filling the cuff (8) of the endotracheal tube (1) with air. The double tube converges at its proximal end into a single fitting (17) with a valve device, for a normal string or for a syringe pump, through which the drugs are injected. Its first double section (12) is external to the endotracheal tube and not attached to it. In its second section, the double device (13, 18) runs through the thickness of the upper and lower walls of the endotracheal tube and ends: that

superiore con una porzione a manicotto circolare di circa 4 cm. immediatamente prima della cuffia con superficie esterna cribrata (19); quello inferiore upper with a circular sleeve portion of about 4 cm. immediately before the cuff with a crystallized outer surface (19); the lower one

(18) termina distalmente alla cuffia endotracheale anch ' esso con una porzione circolare esterna cribrata di un cm. circa, a forma di manicotto (10). I forellini di questi manicotti consentono la irrigazione (18) ends distal to the endotracheal cuff also with an external circular portion of 1 cm. approximately, in the form of a sleeve (10). The holes in these sleeves allow irrigation
