DESCRIZIONE DESCRIPTION

DESCRIZIONE dell’invenzione avente per TITOLO: “SIRINGA CON INCAPPUCCIAMENTO FACILITATO DELL’AGO CHE LIMITA I RISCHI DI PUNTURA ACCIDENTALE DA PARTE DELL’OPERATORE”. DESCRIPTION of the invention with TITLE: "SYRINGE WITH FACILITATED NEEDLE ENCLOSURE THAT LIMITS THE RISKS OF ACCIDENTAL PUNCTURE BY THE OPERATOR".

Le siringhe tradizionali, una volta usate, vengono chiuse tramite un semplice tappo cilindrico che viene calzato sull’ago. Durante l’applicazione del tappo di chiusura, l’ago non ha alcuna protezione e, in caso di non adeguata attenzione, può andare a pungere le dita dell’operatore con rischio di contagi e contaminazioni. Traditional syringes, once used, are closed with a simple cylindrical cap that is fitted onto the needle. During the application of the closure cap, the needle has no protection and, in case of inadequate attention, it can puncture the operator's fingers with the risk of contagion and contamination.

Nella siringa che ho ideato questa funzione di chiusura è delegata ad un sistema fatto da 2 elementi: un guscio di sicurezza più un tappo. Il tappo viene applicato solo dopo aver messo in sicurezza l’ago. In the syringe I designed this closure function is delegated to a system made up of 2 elements: a safety shell plus a cap. The cap is applied only after having secured the needle.

Le parti essenziali della siringa ideata sono: un pistone, un cilindro, un ago, un guscio di sicurezza ed un tappo. Inoltre per facilitare l’assemblaggio ho previsto anche un anello che viene inserito sul guscio di sicurezza dopo che è stato accoppiato con il cilindro. L’anello impedisce al cilindro di uscire dal guscio di sicurezza che può solo traslare vincolato alle guide realizzate nel guscio di sicurezza stesso. Il pistone ed il cilindro sono deputati a creare una depressione per il prelievo del liquido o una leggera sovrapressione per l’iniezione. The essential parts of the designed syringe are: a piston, a cylinder, a needle, a safety shell and a cap. In addition, to facilitate assembly, I have also provided a ring that is inserted on the safety shell after it has been coupled with the cylinder. The ring prevents the cylinder from exiting the safety shell which can only translate bound to the guides made in the safety shell itself. The piston and the cylinder are designed to create a depression for the withdrawal of the liquid or a slight overpressure for the injection.

E’ stata ideata per il pistone un impugnatura ad anello vuoto a centro, che può accogliere al suo interno il dito pollice, il quale spostandosi determina Γ aspirazione (quando il pollice fa estendere il cilindro) o iniezione (quando il pollice comprime il cilindro) della siringa, Tutto il dispositivo può essere retto tra le dita indice e medio»mentre con il pollice si aziona il pompaggio (iniezione o prelievo); è pertanto possibile effettuare un iniezione o prelievo anche con una sola mano, addirittura anche solo con 3 dita. For the piston, a handle with a hollow ring in the center has been devised, which can accommodate the thumb finger inside it, which when moving determines Γ suction (when the thumb extends the cylinder) or injection (when the thumb compresses the cylinder) of the syringe, the whole device can be held between the index and middle fingers "while the thumb is pumping (injection or sampling); it is therefore possible to make an injection or withdrawal even with one hand, even with only 3 fingers.

Il guscio di sicurezza e il cilindro (che a sua volta porta dentro di se il pistone), possono bloccarsi tra loro in due posizioni (TAVOLA 1 “complessivo siringa”, oltre che le TAVOLE 2, 3, 4, 5): The safety shell and the cylinder (which in turn carries the piston inside itself), can lock together in two positions (TABLE 1 "syringe assembly", as well as TABLES 2, 3, 4, 5):

• Posizione “siringa aperta” in cui il guscio è retratto, l'ago fuoriesce interamente, ed è possibile effettuare un prelievo o iniettare. • “Syringe open” position in which the shell is retracted, the needle comes out entirely, and it is possible to take a sample or inject.

a _ Posizione “siringa chiusa” in CUI il guscio protegge la punta dell'ago contenendolo dentro il suo volume. a _ “Syringe closed” position in which the shell protects the tip of the needle containing it within its volume.

Dopo che Pago è messo in sicurezza dentro il guscio, è previsto anche un tappo da applicare come ulteriore protezione (TAVOLA 1 “complessivo siringa” particolare n°5). After Pago is secured inside the shell, a cap is also provided to be applied as an additional protection (TABLE 1 “syringe assembly” detail n ° 5).

Il bloccaggio nelle 2 posizioni è ottenuto da una leggera interferenza dei 2 traversi del cilindro (vedere i 2 tratti cilindrici quotati con diametro 5mm nel disegno “cilindro”) all’ interno dei vani dì bloccaggio (disegno “complessivo siringa”). Locking in the 2 positions is obtained by a slight interference of the 2 cylinder crosspieces (see the 2 cylindrical sections with a diameter of 5mm in the "cylinder" drawing) inside the locking compartments ("syringe assembly" drawing).

Inoltre, sia per isolare ermeticamente il volume attorno la punta della siringa, sia per bloccare ulteriormente la siringa quando si trova in posizione chiusa, è previsto un secondo sistema di incastro tramite una leggera interferenza, come evidenziato anche nella TAVOLA 1 “complessivo siringa” in particolare nella sez. “MM” e dettaglio “S” Quando si deve effettuare il prelievo, si rimuove il tappo, si sblocca il guscio, lo si fa retrarre e si blocca nella nuova posizione, Dopo il prelievo si sblocca nuovamente il guscio, lo si fa scorrere in avanti coprendo la punta e lo si blocca. Furthermore, both to hermetically isolate the volume around the tip of the syringe and to further block the syringe when it is in the closed position, a second interlocking system is provided by means of a slight interference, as also shown in TABLE 1 "syringe assembly" in particular in section "MM" and detail "S" When you need to take the sample, remove the cap, unlock the shell, retract it and lock it in the new position. forward by covering the tip and locking it.

In questa posizione, con l'ago della siringa ormai protetto alTintemo del guscio, si può completare la chiusura applicando (avvitando o incastrando) un tappo sul guscio stesso senza rischio di pungersi. In this position, with the syringe needle now protected inside the shell, the closure can be completed by applying (screwing or fitting) a cap on the shell itself without risk of pricking.

Claims (5)

RIVENDICAZIONI 1. Dispositivi per il prelievo di sangue, ed in generale di liquidi, che hanno un sistema di protezione dell’ago per mezzo di un guscio, che in fase di prelievo è solidale e perfettamente integrato nel dispositivo stesso (in quanto incastrato o avvitato), e che a prelievo avvenuto viene sbloccato e sfilato fino a coprire tutto l’ago, inglobandolo e limitando in tal modo i rischi di puntura accidentale. CLAIMS 1. Devices for blood sampling, and liquids in general, which have a needle protection system by means of a shell, which during the sampling phase is integral and perfectly integrated in the device itself (as it is stuck or screwed) , and that once the drawing has taken place it is unlocked and removed until the whole needle is covered, incorporating it and thus limiting the risks of accidental puncture. 2. Dispositivi per l’iniezione di liquidi, che hanno un sistema di protezione dell’ago per mezzo di un guscio, che in fase di iniezione è solidale e perfettamente integrato nel dispositivo stesso (in quanto incastrato o avvitato), e che a iniezione avvenuta viene sbloccato e sfilato fino a coprire tutto l’ago, inglobandolo e limitando in tal modo i rischi di puntura accidentale. 2.
