Description

Descrizione Description

L’utilità dell’applicazione della pressione positiva espiratoria (PEP) nella ginnastica respiratoria è un dato non recente e convalidato da centinaia di lavori scientifici sia italiani che stranieri. The usefulness of the application of positive expiratory pressure (PEP) in respiratory gymnastics is not recent and has been validated by hundreds of Italian and foreign scientific works.

La più semplice metodica capace di sviluppare la PEP è quella ottenibile mediante la espirazione a labbra socchiuse. Successivamente sono stati proposti altri sistemi meccanici quali: il resistore ad orifizio di diametro predeterminato (Pep Mask), la valvola ad acqua, la biglia d’acciaio (Flutter), la valvola a molla (Threshold), la valvola magnetica (Acapella). In soggetti sani che vogliano aumentare la forza dei muscoli respiratori, ma anche in pazienti convalescenti da malattie debilitanti, può essere consigliato un resistore inspiratorio. The simplest method capable of developing PEP is the one obtainable through the exhalation with parted lips. Subsequently other mechanical systems were proposed such as: the resistor with a predetermined diameter orifice (Pep Mask), the water valve, the steel ball (Flutter), the spring valve (Threshold), the magnetic valve (Acapella). In healthy subjects who want to increase the strength of the respiratory muscles, but also in patients recovering from debilitating diseases, an inspiratory resistor may be recommended.

La caratteristica del Purdev Plus rispetto agli altri dispositivi presenti in commercio è rappresentata dalla multifunzionalità pur essendo un attrezzo di uso estremamente facile e di ridotte dimensioni (lunghezza cm 8, larghezza cm 4, peso g 30). The feature of Purdev Plus compared to other devices on the market is represented by its multifunctionality despite being an extremely easy-to-use and small-sized tool (length 8 cm, width 4 cm, weight 30 g).

In modalità espiratoria , l’inspirazione attraverso il boccaglio è libera e non provoca resistenze significative, mentre l’espirazione sviluppa mediante un sistema a molla, una pressione positiva nelle vie aeree la cui entità dipende in parte dal flusso espiratorio del soggetto utilizzatore, in parte dalla regolazione della tensione della molla tarata. La regolazione è resa possibile dall’ avvitamento del tappo presente nel cilindro piccolo. In expiratory mode, the inhalation through the mouthpiece is free and does not cause significant resistance, while the exhalation develops, through a spring system, a positive pressure in the airways whose extent depends in part on the expiratory flow of the user subject, in part by adjusting the tension of the calibrated spring. The adjustment is made possible by screwing the cap in the small cylinder.

La pressione sviluppata durante l’esercizio è compresa fra 8 e 15 cm di acqua se il paziente respira ad un volume di poco superiore a quello corrente ed espira attivamente contro la resistenza senza forzare possibilmente fino a Capacità di Riserva Espiratoria, provocando un caratteristico scatto. I valori di pressione possono essere letti, respiro per respiro, mediante un manometro collegabile all’apparecchiatura. The pressure developed during exercise is between 8 and 15 cm of water if the patient breathes at a volume slightly higher than the current one and actively exhales against resistance without forcing possibly up to the Expiratory Reserve Capacity, causing a characteristic snap. The pressure values can be read, breath by breath, using a pressure gauge that can be connected to the equipment.

Inoltre l’utilizzatore può intercalare all’esercizio delle inspirazioni profonde sia lente che veloci. Tale manovra corrisponde a quella effettuata mediante la spirometria incentivata sia di volume che, rispettivamente, di flusso. In addition, the user can alternate both slow and fast deep inhalations with the exercise. This maneuver corresponds to that carried out by means of incentivized spirometry both of volume and, respectively, of flow.

In modalità inspiratori a. il boccaglio è collegato dalla parte del cilindro piccolo: inspirazione attraverso il Purdev plus sviluppa una pressione negativa valutabile, se richiesto, respiro per respiro mediante un manometro collegato, Lia pressione sviluppata è in parte dipendente dal flusso inspiratorio, in parte in parte dalla resistenza della molla tarata la cui resistenza è regolabile attraverso le vite contenuta nel cilindro piccolo. In inspiratory mode a. the mouthpiece is connected on the side of the small cylinder: inspiration through the Purdev plus develops a negative pressure which can be evaluated, if required, breath by breath using a connected manometer, The pressure developed is partly dependent on the inspiratory flow, partly partly on the resistance of the calibrated spring whose resistance is adjustable through the screw contained in the small cylinder.

L’apparecchio consente, se collegato ad un manometro la misura ed il monitoraggio della pressione espiratoria ed inspiratoria sviluppata durante l’esercizio nonché la determinazione della Massima Pressione in ed espiratoria (MIP e MEP). Il dispositivo è collegabile al cannello dell’ossigeno. The device allows, if connected to a pressure gauge, the measurement and monitoring of the expiratory and inspiratory pressure developed during exercise as well as the determination of the Maximum in and expiratory pressure (MIP and MEP). The device can be connected to the oxygen torch.

Parte integrante del Purdev Plus è un distanziatore che consente di erogare lo spruzzo di un qualunque spray predosato, mentre il paziente respira attraverso il Purdev in modalità espiratoria, favorendo in tal modo l’inalazione delle particelle dello spray nelle vie aeree più periferiche ed aumentandone l’azione farmacologica broncodilatatrice. An integral part of the Purdev Plus is a spacer that allows the spray of any pre-dosed spray to be delivered, while the patient breathes through the Purdev in expiratory mode, thus favoring the inhalation of the spray particles in the more peripheral airways and increasing the bronchodilator pharmacological action.

Infine il Purdev Plus può essere collegato ad un boccaglio in silicone utile quando il paziente richieda delle sedute di ginnastica respiratoria più lunghe o quando queste vengano effettuate durante il movimento. Finally, the Purdev Plus can be connected to a silicone mouthpiece useful when the patient requires longer respiratory gymnastics sessions or when these are performed during movement.

Purdev Plus è un dispositivo tascabile, in materiale plastico (polipropilene), atossico, sterilizzabile a freddo, costituito da due cilindri sovrapposti ed avente le seguenti dimensioni: diametro di base mm 27 Purdev Plus is a pocket device, in plastic material (polypropylene), non-toxic, cold sterilizable, consisting of two overlapping cylinders and having the following dimensions: base diameter 27 mm

diametro di vertice mm 13 vertex diameter 13 mm

lunghezza mm 63 length mm 63

peso g 15 weight 15 g

Boccaglio per connessione alle labbra mm 55 Mouthpiece for connection to the lips mm 55

Boccaglio per connessione alla bocca ed ai denti mm 60 Mouthpiece for connection to the mouth and teeth mm 60

L’apparecchio contiene una molla in acciaio inox tarata per sviluppare una resistenza di g 4/mm di accorciamento. The device contains a stainless steel spring calibrated to develop a shortening resistance of g 4 / mm.

La molla è inserita in un pistoncino cavo che scorre all’interno del cilindro piccolo che sormonta il cilindro principale del dispositivo. The spring is inserted in a hollow piston that slides inside the small cylinder that surmounts the main cylinder of the device.

Il pistoncino tenuto in sede dalla molla chiude le fessure situate alla base del canale attraverso cui viene consentita la fuoriuscita dell’aria espirata quando il dispositivo viene utilizzato in modalità espiratoria e l’ingresso dell’aria inspirata quando esso viene impiegato in modalità inspiratoria. The piston held in place by the spring closes the slots located at the base of the channel through which the expired air is allowed to escape when the device is used in expiratory mode and the inhaled air to enter when it is used in inspiratory mode.

Un pistone cavo, dotato di un ampio forame centrale, scorre all’interno del cilindro principale ed ha lo scopo, in modalità espiratoria, di chiudere le fessure situate in corrispondenza della parte anteriore del cilindro grande consentendo il passaggio dell’aria esclusivamente dalle fessure situate alla base del cilindro piccolo accorciando la molla in esso contenuta in conseguenza dello sforzo espiratorio e sviluppando una pressione positiva che si trasmette lungo tutto l’albero respiratoria determinando gli effetti fisiopatologici cui sopra abbiamo accennato. A hollow piston, equipped with a large central hole, slides inside the main cylinder and has the purpose, in expiratory mode, to close the slits located at the front of the large cylinder allowing the passage of air exclusively from the slots located at the base of the small cylinder by shortening the spring contained in it as a consequence of the expiratory effort and developing a positive pressure that is transmitted along the entire respiratory shaft, determining the pathophysiological effects mentioned above.

Lo stesso pistone cavo, in modalità inspiratoria, chiude le fessure situate in corrispondenza della faccia anteriore del cilindro grande, consentendo l’ingresso dell’aria inspirata esclusivamente dalle fessure situate alla base del cilindro piccolo e che vengono aperte in seguito all’accorciamento della molla, determinato dallo sforzo dei muscoli inspiratori. La lunghezza della molla può essere regolata mediante il cilindretto cavo posto all’estremità libera del cilindro piccolo in cui è contenuta la molla stessa. La pressione positiva sviluppata dal dispositivo dipende in parte dalla velocità del flusso espiratorio ed in parte dalla tensione della molla. In condizioni basali la regolazione non consente di superare i 20 cm di H20 di pressione anche per flussi espiratori molto elevati. The same hollow piston, in inspiratory mode, closes the slits located at the front face of the large cylinder, allowing the inhaled air to enter exclusively from the slots located at the base of the small cylinder and which are opened following the shortening of the spring , determined by the effort of the inspiratory muscles. The length of the spring can be adjusted by means of the hollow cylinder placed at the free end of the small cylinder in which the spring itself is contained. The positive pressure developed by the device depends partly on the speed of the expiratory flow and partly on the tension of the spring. In basal conditions the regulation does not allow to exceed 20 cm of H20 pressure even for very high expiratory flows.

In modalità espiratoria, il flusso inspiratoria avviene attraverso le fissurazioni anteriori non più chiuse dal pistone cavo che scorre nel cilindro principale e che, essendo sufficientemente larghe offrono una resistenza trascurabile. In expiratory mode, the inspiratory flow occurs through the anterior fissures which are no longer closed by the hollow piston which runs in the main cylinder and which, being sufficiently large, offer negligible resistance.

Il paziente una volta connesso attraverso il boccaglio del dispositivo o attraverso il boccaglio da sub, viene sollecitato ad inspirare spontaneamente dalla bocca o dal naso ed espirare profondamente senza forzare. The patient, once connected through the mouthpiece of the device or through the diving mouthpiece, is prompted to inhale spontaneously from the mouth or nose and exhale deeply without forcing.

In modalità inspiratoria il flusso espiratorio avviene attraverso le fissurazioni anteriori non più chiuse dal pistone cavo e quindi senza sviluppare resistenza. Il flusso inspiratorio avviene attraverso le fessure situate alla base del cilindro piccolo che si aprono progressivamente per lo scorrere del cilindretto cavo contenente la molla, determinando la formazione della resistenza inspiratoria. In inspiratory mode, the expiratory flow occurs through the anterior fissures no longer closed by the hollow piston and therefore without developing resistance. The inspiratory flow occurs through the slits located at the base of the small cylinder which open progressively for the flow of the hollow cylinder containing the spring, determining the formation of inspiratory resistance.
